Quick answer

Validating a heart diagnosis helps patients and families understand whether the diagnosis, test results, severity, urgency, benefits, risks, and treatment options are clear enough before making a decision. If important clinical questions are still unanswered, a second opinion may be considered, as long as it does not delay treatment in an emergency.

When a parent is diagnosed with heart disease, families often come home from the consultation with a lot of information at once: the name of the disease, ECG or echocardiography results, a list of medications, and even a recommended procedure. However, validating a heart diagnosis becomes important when one question still remains: have we truly understood this condition before making the next decision?

Validation here does not mean looking for proof that the previous doctor was wrong. What needs to be confirmed is whether the patient and family understand what the diagnosis is, what the assessment is based on, how serious and urgent the condition is, and why a particular treatment is recommended.

If important questions are still unanswered after discussing them again with the doctor, a second opinion, or second medical opinion, can be one way to gain an additional perspective. In Indonesia, Article 276 of Law Number 17 of 2023 on Health states that patients have the right to receive information and explanations about their health, to access the information in their medical records, and to request the opinion of other medical or health professionals. ^[1]

This article helps you recognize seven things that need to be confirmed, tell when it is enough to ask for another explanation and when a second opinion is worth considering, and understand when seeking an additional opinion must not delay getting help.

What Is Diagnosis Validation?

Diagnosis validation means making sure that the diagnosis and the clinical reasoning behind it are understood clearly enough to help the patient make the next decision. In this article, the term heart diagnosis validation is used as an educational term, not as the name of a standard medical procedure.

The process can start by asking the treating doctor to explain certain information again, reviewing how the test results relate to the diagnosis, or getting an additional medical opinion when it is truly needed.

Validation Is Not About Finding a Doctor’s Mistake

When families receive a lot of information that is hard to understand, a question like this easily comes up:

“Which doctor is right?”

However, a more helpful question is:

“What is the doctor’s assessment based on, and do we understand the reasons behind the recommendation?”

A second opinion does not always lead to a different diagnosis or recommendation. A second opinion can:

reinforce the previous assessment;
clarify the clinical reasoning;
add a perspective from another area of expertise;
identify information that still needs to be completed; or
produce different considerations.

That is why the success of a second opinion should not be judged by how different the answer is, but by whether the patient gains a better understanding for making a decision.

The Indonesian Ministry of Health (Kemenkes) also describes a second opinion as one way for patients or families to obtain another doctor’s opinion in the decision-making process. ^[2]

What Is Actually Being Validated?

In heart disease, understanding the name of the diagnosis alone is not always enough. Patients and families also need to know:

what data support the diagnosis;
how serious the condition is;
whether the condition needs to be treated immediately;
what the goal of the recommended therapy is;
the most relevant benefits and risks;
the limitations of each option;
whether there are other alternatives; and
what might happen if the decision is postponed.

In other words, what is being reviewed is not just the disease label, but the entire path from diagnosis to the next decision.

Why Should a Diagnosis Be Reviewed?

A heart disease diagnosis is usually built from several sources of information, not a single test result on its own. Symptoms, medical history, the doctor’s examination, laboratory tests, ECG, imaging, and the course of the condition can play different roles depending on the disease being assessed.

For example, the American Heart Association explains that when evaluating a heart attack, the medical team may use blood tests and various other tests such as ECG, echocardiography, coronary angiography, cardiac CT, or MRI according to clinical needs. ^[5]

The Indonesian Heart Association (PERKI) also includes clinical findings, ECG, biomarkers, and other tests as part of the evaluation of acute coronary syndrome. ^[3]

This means that a single result should not be separated from the patient’s overall context.

Tests Answer Different Questions

Each test has a different function. For example:

An ECG records the heart’s electrical activity and helps assess rhythm and certain electrical changes.
Echocardiography uses sound waves to show the structure and function of the heart, including how the valves work and how well the heart pumps blood.
Cardiac CT can provide images of the anatomy of the heart and blood vessels for certain indications.
Cardiac MRI can provide detailed information about the heart’s structure, function, blood flow, and tissue in certain conditions.
Coronary angiography is used in certain situations to evaluate the coronary arteries.

However, not all patients need all of these tests. The doctor chooses tests based on the patient’s condition and the clinical question that needs to be answered.

Different Results Are Not Always Contradictory

Test results that look different do not automatically mean that one of them is wrong.

the tests were done at different times;
the patient’s condition changed;
each method measures a different aspect;
the available data are not the same; or
the tests were done to answer different clinical questions.

So if two reports do not seem to line up, do not rush to draw your own conclusions. Ask the doctor how the two results relate to each other in the context of the patient’s condition.

7 Things to Confirm

Before using a diagnosis as the basis for an important medical decision, families need to understand seven things: the diagnosis, the basis for the assessment, severity and urgency, treatment goals, benefits and risks, alternatives, and the relevant doctor expertise.

1. What Is the Main Diagnosis?

Start with the most basic question: what exactly is my parent’s main diagnosis?

Make sure the family can explain it back in simple language.

If the doctor uses terms such as suspected, possible, or working diagnosis, ask what they mean. Uncertainty at a certain stage does not always mean there is a mistake; the doctor may indeed still need additional information.

Questions you can ask:

What is the patient’s main diagnosis?
Is this diagnosis certain enough?
Are other diagnoses still being considered?
Which parts are already clear?
What still needs to be evaluated?
How does this diagnosis explain the patient’s symptoms?

2. What Is the Diagnosis Based On?

Next, ask: “What information most strongly supports this diagnosis?”

The basis can come from a combination of symptoms, medical history, physical examination, ECG, echocardiography, laboratory tests, CT or MRI, angiography, or other tests depending on the condition.

The goal is not for the family to interpret the results themselves, but to understand how the doctor reached a conclusion. Also ask which results have the most influence on the decision and which serve only as supporting information.

3. How Serious and How Urgent?

Severity and urgency are related, but they are not always the same. Severity describes how much disruption or impact the disease causes. Urgency, on the other hand, answers how quickly evaluation or treatment needs to happen.

Do not use other patients’ experiences as a benchmark. Two patients with the same disease name can have different anatomy, heart function, coexisting conditions, and risks.

So ask separately:

How does the doctor assess the severity of this condition?
Is the patient’s condition currently stable?
Does a decision have to be made immediately?
If there is still room for discussion, how much time does the doctor consider safe?
What needs to be monitored while waiting?
What symptoms should prompt the family to seek help right away?

4. What Is the Goal of Treatment?

Families often know the name of the procedure but do not yet understand its purpose. Yet the question “why” is just as important as “what.”

Treatment can aim to reduce symptoms, improve blood flow, control rhythm disorders, improve or maintain heart function, lower the risk of certain events, manage an acute condition, or maintain quality of life.

“What do we want to achieve with this treatment?”

“How will we know that the goal has been achieved?”

5. What Are the Benefits and Risks?

An informed decision requires an understanding of the benefits, risks, limitations, and alternatives that are relevant to that patient.

What needs to be discussed is not just a list of general complications. Ask about the main expected benefits, the most relevant risks, the limitations of the therapy, what may not change, the recovery process, and follow-up care after the procedure.

What are the main expected benefits?
Which risks are most relevant to the patient’s condition?
What are the limitations of this therapy?
What may not change after the procedure?
What is the recovery process like?
What care is still needed after the procedure?

In coronary revascularization decisions, for example, the ACC/AHA/SCAI guideline emphasizes clear communication about benefits, risks, alternatives, quality of life, and patient preferences as part of shared decision-making. ^[7]

If the doctor gives figures on risk or the chance of success, you can ask:

“How relevant are those figures to my parent’s condition?”

This is because figures from a study do not always apply in exactly the same way to every individual.

6. Are There Other Options?

Treatment options differ according to the diagnosis, severity, treatment goals, and the patient’s condition.

In some cases, the options may include monitoring, risk factor control, medication, catheter-based procedures, surgery, a combination of several approaches, or additional tests before deciding on a step.

Even so, not all of these options apply to every patient.

“Which options are medically relevant for my parent’s condition?”

Then compare:

the goal of each option;
benefits;
risks;
limitations;
recovery needs; and
the consequences if it is not done yet.

7. Is the Doctor’s Expertise the Right Fit?

Heart doctors can have different areas of expertise or clinical focus. That is why the doctor who is relevant for one question is not necessarily the most suitable doctor for another question.

Not all patients need many doctors or a Heart Team.

Issue being assessed	Field that may be relevant*
Coronary disease, catheterization, stent	Interventional cardiology
Arrhythmia, ablation, pacemaker	Arrhythmia and electrophysiology
Valve disease or heart structure	Valve disease, structural heart disease, or cardiovascular imaging as needed
Considering surgery	Cardiovascular surgery
Congenital heart disease	Pediatric cardiology and congenital heart disease
Complex options across fields	Multidisciplinary discussion when needed

*This mapping is general. The doctor still determines the need for consultation based on the patient’s condition.

In coronary disease, for example, the ACC/AHA/SCAI guideline recommends a Heart Team approach especially when the optimal revascularization strategy is not yet clear. ^[7]

“Which area of expertise is most relevant for answering our clinical question?”

Another Explanation or a Second Opinion?

If what is unclear is mainly the language or the explanation, asking the same doctor to explain again can be the first step. A second opinion is more relevant when important clinical questions remain unanswered or a major decision needs to be reviewed from an additional perspective.

When Is Asking for an Explanation Enough?

Discuss things again with the treating doctor if:

medical terms are not yet understood;
the meaning of the test results is not yet clear;
the benefits or risks have not yet been discussed;
the goal of treatment is not yet understood; or
the family needs time to put together their questions.

“Doctor, what do these results mean for my father’s condition?”

“Of all these tests, which result has the most influence on the decision?”

Simple questions like these can help make the discussion with the doctor more focused.

When Should a Second Opinion Be Considered?

A second opinion may be considered if:

the diagnosis still leaves meaningful uncertainty;
a major or complex procedure is being considered;
there are several options that are difficult to compare;
medical recommendations differ;
the benefits and risks still cannot be understood; or
a perspective from a particular area of expertise is needed.

The American Heart Association mentions decisions about major procedures as one of the situations in which patients may consider an additional medical opinion, and recommends bringing medical records and specific questions to the consultation. ^[4]

However, a second opinion is not an obligation for every patient.

Preparing Before a Second Opinion

Preparing for a second opinion should focus on two things: relevant medical information and the questions you want answered. The documents do not have to be perfect to get started.

Create a Timeline of the Condition

Note down simply:

when the symptoms appeared;
how the condition changed;
diagnoses that have been given;
medications currently or previously used;
procedures that have been done; and
changes in the condition after therapy.

A timeline helps the doctor understand the course of the condition without relying only on the family’s memory.

Gather Medical Documents

If available, prepare:

a medical summary;
ECG;
echocardiography results;
laboratory results;
CT/MRI if relevant;
angiography reports or files;
previous procedure reports; and
a list of current medications.

Not all patients need to have all of these documents.

Heartology currently also states that the initial process can start with the documents that are available. A Heart Consultant can help identify relevant information, while the doctor determines whether the data are sufficient. ^[8]

If Doctors’ Opinions Are the Same or Different

Different doctors’ opinions do not automatically mean that one of them is wrong. Differences can arise because the data reviewed are different, the timing of the evaluation is different, the patient’s condition has changed, the areas of expertise are not the same, or there is more than one medically reasonable option.

If the Opinions Are the Same

A matching second opinion can still be beneficial if it helps the patient:

understand the clinical reasoning;
know which data are most important;
get a chance to ask questions; and
understand the next steps.

However, two matching opinions do not guarantee the treatment outcome with absolute certainty.

If the Opinions Are Different

Do not just compare the doctors’ names or their final conclusions. Compare:

the diagnosis used;
the data reviewed;
severity;
treatment goals;
benefits;
risks;
alternatives;
urgency; and
information that is not yet available.

This way, the family can understand why the recommendations differ.

The Role of Children in Supporting Parents

Children can help organize information and accompany discussions, but as long as the condition allows, the patient should still be involved in decisions about their own care.

Children are often the ones who:

take notes on explanations;
keep the test results;
manage schedules;
look for information;
prepare questions; and
help the family understand information from the doctor.

This role is very helpful. However, accompanying is not the same as taking over the decision.

Distinguish Between Worries and the Patient’s Priorities

“What matters is doing the most complete procedure.”

However, parents may have other considerations, such as the ability to return to their activities, the length of recovery, dependence on family, the effects of therapy on daily life, or the burden of care they are willing to go through.

In shared decision-making, medical evidence needs to be discussed together with the patient’s goals, values, and preferences. The ACC/AHA/SCAI guideline also emphasizes active patient participation and family support in treatment decisions. ^[7]

So before the consultation, ask:

What matters most to your parents?
What worries them the most?
What activities do they want to keep doing or return to?
What information still leaves them unsure?

Patients From Outside Greater Jakarta

Patients from outside Greater Jakarta (Jabodetabek) should confirm the clinical purpose of the consultation before arranging travel to Jakarta. This step can help the family prepare the doctor, documents, time, and travel needs in a more focused way.

First decide whether you want to:

clarify the diagnosis;
assess a recommended procedure;
compare several options;
get a perspective from a particular area of expertise; or
find out whether follow-up care needs to be done in Jakarta.

In addition, prepare medical documents and questions before traveling.

Heartology currently provides a pathway in which the data are reviewed first for many cases. Consultations can be done in person or virtually depending on needs and clinical suitability. If a physical examination or in-person evaluation is needed, the doctor may recommend a visit. ^[8]

“What is the medical purpose of the visit, and does the patient really need to be there in person?”

When Should You Seek Help?

A second opinion must not delay help for a condition suspected to be an emergency.

The American Heart Association explains that a heart attack can appear as chest pressure or pain, shortness of breath, discomfort in the upper body, cold sweats, nausea, or lightheadedness. Symptoms can also start slowly and do not always feel very severe from the start. ^[6]

The Indonesian Ministry of Health also emphasizes that chest pain lasting several minutes, especially when accompanied by shortness of breath, cold sweats, or spreading pain, needs immediate medical help. ^[9]

Do not wait for a second opinion appointment or a response to an online form if the condition appears acute.

Heartology itself states that the Second Opinion service is not an emergency service and directs patients with emergencies to the Heart Attack Center or the emergency department (ER). ^[8]

How a Second Opinion Helps

In the process of validating a heart diagnosis, a second opinion helps review the information already available and focuses the discussion on clinical questions that remain unanswered.

A second opinion does not mean that the entire process has to be repeated from the beginning.

Reviewing Existing Information

The doctor can assess:

medical history;
the timeline of symptoms;
test results;
imaging;
medications used;
previous procedures; and
recommendations already given.

After that, the doctor determines whether the information is sufficient or still needs to be completed.

Answering the Remaining Questions

Is the diagnosis clear enough?
How severe is it?
How urgent is the procedure?
What is the goal of therapy?
Are there other options?
Is specific expertise needed?

Guiding the Next Steps

After the evaluation, the next step may be:

continuing the previous plan;
adding information;
doing certain tests;
considering other options; or
consulting a more relevant area of expertise.

The goal is not to produce a decision that is “definitely right,” but to help the patient make a decision based on more complete information.

Choosing the Right Doctor

Choose a second opinion doctor based on how well their expertise matches the patient’s clinical question, not on popularity alone.

“What problem do we actually want to confirm?”

For example:

Does the coronary narrowing really need a procedure?
Does the arrhythmia require ablation?
How severe is the valve abnormality?
Is surgery a relevant option?
Are there several approaches that need to be compared?

The Heartology directory currently also shows each doctor’s areas of expertise so that patients can match their choice to their clinical needs. ^[8]

When Is a Heart Team Relevant?

Not all cases need a multidisciplinary discussion. A Heart Team is more relevant in situations where the clinical options involve several fields or the optimal strategy is not yet clear.

In coronary revascularization, the ACC/AHA/SCAI guideline specifically recommends a Heart Team approach when the optimal strategy cannot be clearly determined.

Heartology also states that more complex cases can be discussed in a Heart Meeting, although not all patients need one.

The Heartology Second Opinion Process

Heartology Second Opinion starts by understanding the decision the patient is facing, then reviews the relevant medical information before determining the next consultation needs.

1. Describe the Situation

The patient or family explains:

the diagnosis received;
the recommended procedure;
previous medical opinions; and
questions that are still unanswered.

2. Prepare Medical Information

Available test results and medical records can be submitted through official channels. Not all documents need to be complete to start coordinating.

3. Match the Doctor to the Case

The patient is directed to a doctor with relevant expertise.

4. The Doctor Reviews the Information

The doctor assesses the available data and determines whether additional tests or information are needed.

5. Understand the Next Steps

The patient receives an explanation of the diagnosis, options, benefits, risks, and next steps.

For certain cases, the consultation can be done virtually. If an in-person evaluation is needed, the patient may be asked to come in. Complex cases can also be discussed in a Heart Meeting according to clinical needs. ^[8]

Medical decisions should still involve the patient according to their ability and preferences, with family support if the patient wishes.

Questions to Ask During the Consultation

You do not need to be a health professional to ask questions that help with decisions. Keep these 12 questions:

What is my parent’s main diagnosis?
What are the most important data supporting that diagnosis?
What is already certain enough, and what still needs to be evaluated?
How does the doctor assess its severity?
How urgent is the next step?
What is the goal of the recommended treatment?
What benefits can realistically be expected?
What are the risks and limitations?
Are there other relevant options?
What might happen if treatment is postponed?
Are additional tests still needed?
What symptoms should prompt us to seek help right away?

If you only have time for one more question, ask:

“Of all this information, what is the most important thing we need to understand before making a decision?”

Next Steps

If a parent’s heart diagnosis still leaves questions, start by determining which part is unclear, rather than immediately seeking as many opinions as possible.

Note What Is Not Yet Understood

Is the confusion related to:

the diagnosis;
test results;
severity;
urgency;
the procedure;
benefits and risks; or
alternatives?

Discuss It Again With the Doctor

Be specific about which part is not yet understood.

“We understand the name of the diagnosis, but we do not yet understand why this procedure needs to be done now.”

A simple statement like this can make the consultation much more focused.

Consider an Additional Perspective

If important clinical questions remain after a repeat explanation, a second opinion from a doctor with the appropriate expertise can be the next step.

The ultimate goal is not to obtain absolute certainty. In medical practice, not every decision has an answer that is completely free of uncertainty.

What patients and families need is information that is sufficient, relevant, honest, and understandable so that decisions can be made according to the patient’s condition and priorities. With this approach, validating a heart diagnosis helps families move from feeling unsure toward a more focused understanding without having to assume the previous doctor was wrong.

Medical Note

This article is educational and does not replace the examination, diagnosis, or recommendations of a doctor who knows the patient’s condition directly.

The need for additional tests, a second opinion, a multidisciplinary consultation, a procedure, or an in-person consultation is determined based on the patient’s condition and the available medical data.

In an emergency, do not wait for a second opinion consultation. Seek help immediately at the nearest emergency department (ER) or emergency service.
