Unclear Heart Disease Diagnosis? Understand What It Means and Your Next Steps

When a heart disease diagnosis is unclear, you may already know the name of the condition the doctor mentioned but not yet understand how severe it is, which test results support it, or why a particular procedure was recommended. Patients and families alike can experience this kind of confusion, especially when a lot of information is given in a single consultation.

The situation can feel even harder if you live outside Greater Jakarta (Jabodetabek), were not accompanied by family during the consultation, or received an explanation full of unfamiliar medical terms. However, a diagnosis that is not yet understood does not always mean that the diagnosis is wrong.

Doctors generally build a cardiovascular diagnosis by connecting the pattern of symptoms, health history, physical examination, risk factors, and the results of supporting tests. ECG, echocardiography, CT, MRI, and other tests have different functions, so they should not be assessed in isolation.

Therefore, the first step is not to guess on your own or immediately repeat all the tests. Start by identifying which part is unclear, preparing questions, and gathering relevant medical information.

This article helps you understand:

• what an unclear diagnosis means;
• why test results can look different;
• signs that you need further explanation;
• the documents you should prepare;
• when a second opinion may be considered; and
• when a condition should not wait for a scheduled consultation.

This information is educational and does not replace a consultation, examination, or recommendation from a doctor who understands your condition.

01 / Cardiovascular Therapy

What Does an Unclear Diagnosis Mean?

A diagnosis that feels unclear may mean that the diagnosis exists but is not yet understood, is still provisional, involves several possible conditions, or is not yet supported by enough information to answer all the clinical questions.

This distinction matters. A patient who only needs the explanation repeated does not necessarily need new tests. Conversely, the explanation may be incomplete if important medical data are not yet available.

The Diagnosis Exists but Is Not Yet Understood

In this situation, the doctor may have already shared a medical conclusion. However, the patient or family cannot yet explain back:

• what the main condition is;
• which part of the heart is involved;
• how severe or urgent the condition is;
• which test results support the diagnosis; or
• why certain medications, tests, or procedures are recommended.

This can happen because a consultation contains a lot of information at once. The patient may hear explanations about heart anatomy, test results, medications, the benefits of a procedure, and its risks in a single meeting. In addition, nervousness can make information harder to process.

An appropriate first step is to ask for the explanation again in simpler language. Making decisions together (shared decision-making) treats the patient and the doctor as partners in choosing tests, therapies, and a care plan that fit both the medical evidence and the patient’s needs.

You can ask:

• “What is the main diagnosis being treated?”
• “Which parts can already be confirmed?”
• “Which test results most support this diagnosis?”
• “What information is still not available?”
• “What is the next step, and how urgent is it?”

The Diagnosis Is Still Provisional

A provisional diagnosis is an initial conclusion based on the information available at the time. The doctor may use it while:

• waiting for additional test results;
• observing how the symptoms develop;
• comparing several possible causes; or
• assessing how other illnesses affect the heart.

The term “provisional” does not mean the diagnosis was given without a basis. Rather, it indicates that the conclusion can be updated when new information becomes available.

For example, palpitations that come and go may not appear during a brief ECG. In certain conditions, the doctor may consider longer rhythm monitoring. However, that need is still determined by the pattern of symptoms, the clinical findings, and each patient’s condition.

Several Possible Conditions Remain

Chest pain, shortness of breath, tiring easily, dizziness, or palpitations can occur in a variety of conditions. Therefore, doctors sometimes draw up a differential diagnosis, which is a list of several possibilities that still need to be compared.

This process is not only about finding symptoms that fit a particular disease. Doctors also pay attention to:

• findings that do not fit;
• risk factors;
• the physical examination;
• changes in symptoms over time; and
• the results of supporting tests.

A differential diagnosis list should not be used to diagnose yourself. Its purpose is to help the doctor determine what information is still needed to narrow down the possibilities.

Tests Have Not Answered Everything

Each heart test is designed to answer a specific question. For example:

• an ECG assesses electrical activity;
• echocardiography assesses structure and function;
• a Holter monitor records heart rhythm over a longer period;
• CT angiography assesses the anatomy of the coronary arteries; and
• coronary angiography views the blood vessels through a catheter procedure.

Thus, a normal result on one test does not automatically rule out all heart disease. That result still needs to be linked to the symptoms, history, physical examination, and other information.

02 / Cardiovascular Therapy

Why Is a Diagnosis Hard to Understand?

A heart disease diagnosis can feel complicated because the doctor may need to assess electrical activity, structure, valves, pumping function, the coronary arteries, and the influence of other health conditions all at the same time.

Heart Conditions Involve Many Aspects

Two patients with similar symptoms do not necessarily have the same cause or the same testing needs.

To illustrate:

• Palpitations may be related to a rhythm disorder, but medication use, anemia, thyroid function, or other factors may also be relevant.
• Shortness of breath may be related to pumping function, the valves, heart rhythm, the lungs, or conditions outside the heart.
• Chest pain may come from the heart, but it may also have other causes that still require medical assessment.

Therefore, doctors do not just look for a single “positive” or “negative” result. AHA and ACC guidelines recommend structured risk assessment and selecting tests for the patients most likely to benefit, rather than using the same testing approach for everyone.

Medical Terms Are Not Always Easy to Understand

Medical reports are written to document findings precisely. As a result, you may come across terms such as:

• ejection fraction;
• ischemia;
• regurgitation;
• stenosis;
• hypertrophy;
• arrhythmia;
• calcification; or
• coronary lesion.

Looking up these terms one by one on the internet can add to the confusion. A single term does not necessarily have the same impact on every patient. Its meaning needs to be linked to the location, degree, symptoms, heart function, coexisting conditions, and the purpose of the test.

When you come across a term you do not understand, ask three things:

1. What does it mean in simple terms?
2. How does it affect my condition?
3. Does this finding change the care plan?

The Consultation Feels Like Too Much Information

A heart consultation may cover the diagnosis, medication changes, additional tests, activity restrictions, and procedure plans all at once.

To make the information easier to process:

• bring a companion if the patient agrees;
• write down three to five priority questions;
• note the name of the diagnosis and the next steps;
• repeat your understanding back to the doctor; and
• ask for a written summary if available.

For example, you could say, “So what I understand is that this condition does not need to be treated right away, but I need to have additional tests. Is that right?”

Open communication and the patient’s ability to ask for another explanation are important parts of patient-centered cardiovascular care.

Medical Information Is Incomplete

A doctor’s conclusion depends on the information available for review. In a first consultation or a second opinion, the doctor may not yet have received:

• the original test images;
• reports of previous procedures;
• a complete medication list;
• a timeline of changes in symptoms;
• a history of allergies or coexisting conditions; or
• results from other healthcare facilities.

A photo of a one-page report sent through a messaging app does not necessarily replace the original series of images or recordings. Therefore, the doctor may request additional documents or suggest repeating a test if the available information is not sufficient.

Doctors’ Recommendations Can Differ

Different recommendations do not automatically mean that one of the doctors is mistaken. Differences can be influenced by:

• the information reviewed;
• the timing of tests;
• changes in the patient’s condition;
• the doctor’s area of expertise;
• the weighing of benefits and risks;
• coexisting conditions; or
• the existence of more than one clinically reasonable option.

Patient-centered care combines medical evidence, clinical expertise, individual circumstances, and the patient’s values and goals.

03 / Cardiovascular Therapy

Why Do Test Results Differ?

Heart test results can look different because each test assesses a different aspect. The timing of the test, the patient’s condition, image quality, and the clinical question to be answered can also affect the information obtained.

Electrocardiogram or ECG

An electrocardiogram (ECG) records the heart’s electrical activity. This test can show heart rate, rhythm regularity, and certain electrical signal patterns.

However, an ECG only records what is happening during the test. Therefore:

• disturbances that occur only occasionally may not be captured;
• an ECG does not assess every aspect of the heart’s structure;
• a normal result does not rule out all conditions; and
• an abnormal result still needs to be interpreted in a clinical context.

ECG recordings must be assessed by trained medical professionals. Patients are advised not to draw conclusions about a diagnosis based only on the automated text printed by the machine.

Holter Monitor

A Holter monitor records electrical activity over a longer period while the patient goes about daily activities. This test can help link the timing of symptoms with the recorded rhythm.

Patients are usually asked to note:

• when symptoms appear;
• the activity being done at the time;
• the type and duration of symptoms; and
• when medications are taken.

Even so, a Holter is not needed for every symptom. In addition, the disturbance may not appear during the recording period.

Echocardiography

Echocardiography uses sound waves to produce images of the heart. This test can help assess the size of the heart chambers, wall motion, pumping strength, the valves, and some aspects of blood flow.

Echocardiography reports often contain many measurements. A single number should not be interpreted in isolation because the doctor also needs to consider:

• the images as a whole;
• imaging quality;
• the type of test;
• the patient’s symptoms; and
• other clinical conditions.

Coronary CT Angiography

A cardiac CT scan or coronary CT angiography uses CT and an iodine-containing contrast agent to view the coronary arteries and assess whether there is narrowing. The resulting images can be reconstructed into a three-dimensional view.

The choice of test takes into account, among other things:

• the clinical question;
• kidney function;
• any history of contrast allergy;
• heart rhythm and heart rate;
• radiation exposure; and
• the patient’s ability to follow the procedure.

CT angiography is a diagnostic test. Any narrowing found cannot be treated directly through this test.

Coronary Angiography

Coronary angiography uses a catheter, contrast dye, and X-ray imaging to view the coronary arteries. In certain contexts, catheterization can also be used to measure pressure or be followed by a procedure if it is indicated.

Undergoing angiography does not mean the patient will definitely need a stent. The decision to intervene takes into account:

• the location and degree of narrowing;
• symptoms;
• the effect of the narrowing on blood flow;
• the patient’s health condition;
• the benefits and risks of the procedure; and
• other treatment options.

Comparison of Tests

Thus, choosing the right test matters more than doing as many tests as possible. Tests should be chosen to answer specific clinical questions and used when their results may influence decisions.

To understand the testing options more broadly, read also types of heart tests and how they differ.

Signs You Need Further Explanation

You need additional explanation if the unclear diagnosis keeps you from understanding your condition, assessing the urgency, or taking part in care decisions. This does not automatically mean you must change doctors or immediately seek a second opinion.

You Cannot Yet Explain the Diagnosis in Your Own Words

After the consultation, try to answer:

• What is the name of my main condition?
• Which part of the heart is involved?
• Is the diagnosis definite or still provisional?
• How does it affect my health or activities?
• What is the next step?

You do not need to master the technical terms. However, you do need to understand the big picture. If you cannot yet answer these basic questions, ask for the explanation again.

The Basis for Treatment Is Not Yet Understood

Before agreeing to an important test or procedure, make sure you know:

• the purpose of the procedure;
• the benefits that can realistically be expected;
• the risks and limitations;
• other available options;
• the level of urgency; and
• the consequences if the procedure is postponed or not done.

Shared decision-making means the doctor explains the relevant evidence and options, while the patient shares their goals, concerns, preferences, and personal circumstances.

The Results Seem Inconsistent

You may see a normal ECG, yet the echocardiography shows impaired function. In another situation, a CT scan shows narrowing even though the symptoms feel mild.

Findings like these are not necessarily contradictory because the tests assess different aspects. Ask:

• Which finding is most relevant to my symptoms?
• Do the results complement each other?
• Were the tests done at different times or under different conditions?
• Do the original images need to be reviewed?
• What information is still missing?

The Diagnosis Involves Several Conditions

Decisions become more complex when a patient has more than one condition, for example valve disease and coronary disease, a rhythm disorder and reduced pumping function, or heart disease affected by a kidney disorder.

In certain cases, coordination between several areas of expertise can help bring the perspectives together. The ACC/AHA/SCAI guidelines recommend a Heart Team approach when the optimal revascularization strategy is unclear. However, that need is determined by the characteristics of the case and does not automatically apply to every patient.

Not Yet Ready to Make a Decision

Not feeling ready does not mean you are refusing care. There may still be important questions that have not been answered.

Identify the source of your doubts:

• Is the diagnosis not yet understood?
• Are the benefits and risks still unclear?
• Do the doctors’ recommendations differ?
• Does the family need time to talk it over?
• Do costs and travel need to be arranged?
• Is the level of urgency still unknown?

When a heart disease diagnosis is unclear, identifying the source of confusion helps you decide whether the next step is clarification, completing documents, additional tests, or a second opinion.

05 / Cardiovascular Therapy

Steps Before a Second Opinion

Before seeking a second opinion, organize your questions and the medical information you already have. Good preparation helps the doctor understand the context of the case and reduces the chance that the consultation simply repeats the same information.

Ask for Another Explanation

Start with four core questions:

1. What is the main diagnosis being considered?
2. What is already known, and what is still unknown?
3. What are the purpose and urgency of the next step?
4. What are the benefits, risks, and alternatives?

Asking for simpler language is a normal part of medical communication.

Separate What Is Already Known

Divide your notes into two parts.

Already known:

• The diagnosis or main suspected condition
• The pattern and timing of symptoms
• Available test results
• Medications currently being taken
• The plan that has been recommended

Still needs to be understood:

• Severity
• Main cause
• Information that is still incomplete
• The purpose of additional tests
• Benefits, risks, and alternatives
• Level of urgency
• Whether a visit to a referral hospital is needed

This format helps patients, families, and doctors discuss the same issues in a more structured way.

Write Down Priority Questions

Choose three to five questions that most affect the decision, for example:

• Does this procedure need to be done immediately?
• Are there options other than surgery?
• Can the files from previous tests still be used?
• Do I need to see a particular subspecialist?
• Can the initial evaluation be done online?

Gather Medical Documents

Documents that may be needed include:

• consultation or hospitalization summaries;
• laboratory results;
• ECG reports;
• echocardiography reports and image files;
• Holter monitor results;
• CT, MRI, or angiography reports and images;
• reports of previous procedures;
• a list of medications and doses;
• allergy history; and
• a timeline of symptoms.

Not every patient will have all of these documents. However, complete documents that can be opened will help the doctor assess what is already known and what information is still needed.

Do not stop or change your medications to prepare for a second opinion unless the treating doctor has instructed you to do so.

More complete guidance is available in the article on preparing for your first heart consultation and on the Heartology appointment checklist page.

Confirm the Level of Urgency

Before waiting for an appointment with another doctor, ask:

• Can the condition wait for a scheduled consultation?
• Is there a time limit for the test or procedure?
• Which symptoms require immediate help?
• Is long-distance travel safe?
• Should medications be continued while waiting?

There is no single time limit that applies to all heart diseases. The doctor must determine it based on the individual condition.

06 / Cardiovascular Therapy

Benefits of a Cardiac Second Opinion

A second opinion is another doctor’s assessment of a diagnosis, test results, or care plan that has already been given. A second opinion can confirm the initial plan, provide additional explanation, or point out information that still needs to be completed.

The Indonesian Ministry of Health (Kemenkes) explains that patients and families may seek another doctor’s opinion as part of their involvement in decision-making. Patients should bring their medical notes and test results, while the second doctor may request additional evaluation if needed.

Reviewing the Diagnosis and Tests

In a second opinion consultation, the doctor can assess:

• whether the symptoms and history fit the diagnosis;
• how the test results relate to the conclusion;
• how complete the information is;
• whether the timing of the tests is still relevant;
• the possibility of other conditions; and
• the need for a physical examination or additional tests.

A review is not always adequate if it only involves reading the conclusion on the last page. For imaging tests, the original image files can provide information that is not fully written in the report.

Confirming the Initial Plan

A second opinion does not have to produce a different answer to be useful. Confirmation can help the patient understand that the diagnosis or initial plan has been reviewed from another perspective.

A systematic review of patient-initiated second opinions found that second opinions often confirm the initial diagnosis or plan. However, that evidence comes from various medical fields and cannot be used to promise any particular outcome for heart patients.

Understanding Treatment Options

When there is more than one option, the second doctor can help explain:

• the goal of each option;
• the expected benefits;
• the risks and limitations;
• relevant alternatives;
• the consequences of delay;
• the sequence of treatment; and
• how the patient’s condition affects the choice.

The value of a second opinion lies not in finding the answer you like most, but in understanding the medical reasoning behind each option.

Identifying the Information Needed

The second doctor may judge that the available data are not sufficient. The next step may include:

• requesting the original images;
• comparing old and new results;
• updating tests that no longer reflect the current condition;
• doing tests to answer other questions;
• examining the patient in person; or
• involving additional areas of expertise.

Additional tests should be chosen because their results may influence the decision, not simply to repeat the whole process.

Supporting an Informed Decision

Medical decision-making does not only consider what is technically possible. Doctors and patients also need to discuss:

• the patient’s goals;
• coexisting conditions;
• the impact on quality of life;
• readiness to undergo the procedure and recovery;
• family support;
• access to follow-up visits; and
• the patient’s preferences.

This approach is at the core of patient-centered cardiovascular care.

Limits of a Second Opinion

A second opinion does not guarantee:

• a definitive diagnosis in a single consultation;
• a different recommendation;
• that all previous tests can be used right away;
• that no additional tests will be needed;
• that the entire evaluation can be done online;
• a particular treatment outcome; or
• that an emergency is safe to wait.

Understanding these limits helps patients use a second opinion realistically.

07 / Cardiovascular Therapy

Second Opinions and Trust in Your Doctor

Seeking a second opinion does not always mean the patient does not trust the previous doctor. A second opinion can be used to obtain additional explanation, confirm a diagnosis, or understand the options before a major decision.

The first and second doctors do not need to be seen as competing parties. They may see the patient at different times, receive different information, or have different areas of expertise.

To keep the evaluation fair:

• share the previous diagnosis and plan;
• bring the reports and original images;
• explain the medications and procedures you have already had;
• do not hide the first recommendation to “test” the second doctor; and
• ask about the reasons behind any agreement or disagreement.

Open communication helps doctors and patients make decisions based on the same information.

08 / Cardiovascular Therapy

Second Opinions for Patients Outside Greater Jakarta

For patients outside Greater Jakarta, a second opinion often comes with practical questions: whether they need to travel to Jakarta, which documents to bring, and whether tests need to be repeated.

Some of the preparation can start at home. However, remote consultations cannot always replace an in-person evaluation.

Preparation Starts at Home

Before planning a trip, the patient or family can:

• gather reports and images;
• put together a timeline of symptoms;
• note down medications;
• write down priority questions;
• ask about doctors with the appropriate area of expertise;
• confirm which documents can be sent; and
• ask whether an initial online consultation is possible.

The Indonesian Ministry of Health defines telemedicine as remote healthcare delivered through communication technology, which may include evaluating a patient’s condition. This service can help people who live far from healthcare facilities.

What Can Be Discussed Online

Depending on the patient’s condition, the services available, and the quality of the data, an online consultation can help:

• discuss symptoms and health history;
• review the reports that have been sent;
• explain terms or the initial diagnosis;
• identify unanswered questions; and
• plan the next steps.

Heartology lists the evaluation of test results from other facilities and second opinions before procedure decisions as topics that can be discussed through online consultation, with the possibility of planning an in-person examination or follow-up if needed.

When Do You Need to Be Seen in Person?

An in-person visit may be needed when:

• the doctor needs to perform a physical examination;
• symptoms are new or have changed;
• vital data or image files are inadequate;
• additional diagnostic tests are needed;
• a medical procedure is being considered; or
• the patient’s condition is unstable.

Telemedicine can help expand access, but it does not replace every aspect of a clinical examination.

Making the Trip More Purposeful

Before you leave:

• confirm the appointment and the doctor you will see;
• make sure the test files can be opened;
• bring your medications or a medication list;
• ask about test preparation through official instructions;
• decide who will accompany you;
• ask about the administrative steps; and
• set aside enough time in case further evaluation is needed.

The goal is not to make sure the patient does not have to come, but to make sure the trip has a clear medical purpose.

You can also view the Heartology doctors by area of expertise or learn about the services at the Cardiac Diagnostic Center.

09 / Cardiovascular Therapy

Questions to Ask During a Second Opinion

Structured questions help keep the consultation focused. You do not have to ask all of them; choose the ones most relevant to the decision you are facing.

1. What is the main diagnosis being considered?
2. Which parts can already be confirmed?
3. Which parts are still unclear?
4. Which symptoms or tests most support the diagnosis?
5. Are there other conditions that need to be considered?
6. Are the available reports and images sufficient?
7. Are additional tests needed?
8. What question is that test meant to answer?
9. How urgently does this condition need to be treated?
10. What benefits are expected from the care plan?
11. What are its risks and limitations?
12. Are there other relevant options?
13. What could happen if the procedure is postponed?
14. Do I need to be assessed by a particular subspecialist?
15. Is an in-person evaluation or a Heart Team discussion needed?
16. Which symptoms should prompt me to go to the emergency department (ER) right away?

The doctor may identify other issues the patient had not thought of before. Therefore, use this list as a guide, not as a script that must be followed rigidly.

10 / Cardiovascular Therapy

When Doctors’ Opinions Differ

When two doctors give different recommendations, compare the reasoning behind them, rather than simply choosing the conclusion that most closely matches your hopes.

Compare the Reasoning

Ask:

• Which data are considered most important?
• Have all the reports and images been reviewed?
• What is the main goal of the treatment?
• What are the benefits and risks of each option?
• What conditions make one option more suitable?
• How urgent is the decision?
• What are the consequences of choosing the alternative?

Two different recommendations can still both fall within the range of medically justifiable options.

Make Sure the Information Is the Same

Differences can arise when one doctor sees the original images while another only reads the report. The same can happen if one of them does not yet know about the patient’s coexisting conditions or medications.

Make sure both doctors receive:

• the same timeline of symptoms;
• a complete medication list;
• the history of procedures;
• the same reports and images;
• information about changes in the condition; and
• the patient’s goals and preferences.

Consider a Collaborative Evaluation

In certain cases, decisions require input from several fields. For example, choosing between a catheter-based intervention and surgery may involve an interventional cardiologist, a cardiac surgeon, and other specialties depending on the condition.

A Heart Team approach is recommended when the optimal revascularization strategy is unclear and the decision needs to take into account the complexity of the disease, technical feasibility, and the patient’s goals.

Take the Patient’s Condition Into Account

The right option for one patient is not necessarily right for another. Discuss:

• the goals of care;
• expectations for activity and quality of life;
• other illnesses;
• readiness to go through recovery;
• family support;
• the ability to attend follow-up visits; and
• the patient’s priorities after understanding the benefits and risks.

Patient preferences do not replace medical standards. However, they help in choosing between options that are equally relevant clinically.

11 / Cardiovascular Therapy

When Should You Not Wait?

A second opinion is suitable for decisions that can be planned. Acute conditions should not wait for a consultation appointment, documents to be sent, a WhatsApp reply, or an online review.

Heart attack signs do not always appear in the same pattern. Some heart attacks start slowly with milder discomfort. Therefore, do not wait for certainty from internet searches if your symptoms point to an acute condition.

Emergency evaluation requires an in-person assessment. Telemedicine or a second opinion consultation is not the right service for an emergency.

Once the acute condition has been assessed and the patient is stable, questions about the diagnosis, follow-up, or treatment options can be discussed in a scheduled consultation.

Also learn about the symptoms and treatment of acute coronary syndrome.

12 / Cardiovascular Therapy

Conclusion and Next Steps

A diagnosis that is not yet understood does not automatically mean the diagnosis is wrong. Uncertainty can arise because medical terms have not been explained simply, information is incomplete, tests assess different aspects, or the doctor is still comparing several possibilities.

Start with the most basic steps:

• ask about the main diagnosis;
• separate what is already known from what is not;
• understand the level of urgency;
• gather test reports and images;
• note your medications and the timeline of symptoms;
• discuss the benefits, risks, and alternatives; and
• consider a second opinion if important questions or major decisions remain.

For patients outside Greater Jakarta, some of the preparation can start at home. An online consultation may help review initial information, but an in-person examination may still be needed.

You do not need to understand every medical term at once. Focus on four things: what the main diagnosis is, what evidence supports it, what is still unclear, and what the next step is. Individual decisions still need to be discussed with a doctor who understands your condition as a whole.

Ultimately, a second opinion before a cardiovascular procedure should help you understand your options in a more focused way, not delay care that you need. If emergency signs appear, seek medical help immediately.
