Silent Heart Disease: Small Warning Signs That Should Not Be Ignored

By Ahmet Taş | Wise News Press

ISTANBUL, TÜRKİYE — Heart disease does not always begin with severe chest pain; climbing stairs more slowly, tiring sooner than usual, brief palpitations and reduced exercise tolerance may be early warning signs.

Some people gradually reduce their daily activity without realizing it. They walk less, use elevators more often, take additional breaks or avoid physically demanding tasks. Over time, these adjustments can make an underlying decline in physical capacity seem normal.

Professor Burak Onan of the Department of Cardiovascular Surgery at Memorial Bahçelievler Hospital said heart and vascular disorders can progress silently, even when a person feels generally healthy.

The absence of obvious symptoms, he noted, does not necessarily mean that the heart and blood vessels are free of disease.

“Silent heart disease” is not one specific diagnosis

The expression “silent heart disease” is commonly used to describe several cardiovascular conditions that progress without clear symptoms or are diagnosed late because their early signs are overlooked.

It is not the medical name of a single disease.

Narrowing of the coronary arteries, some heart valve disorders, abnormal heart rhythms and enlargement of the aorta may develop for a long period without causing dramatic symptoms.

In some patients, a cardiovascular problem is discovered incidentally during a routine physical examination, blood pressure check, preoperative assessment or imaging performed for an unrelated reason.

A clinician may hear an unusual heart sound, identify an irregular rhythm or notice an abnormality on a scan before the patient reports any significant discomfort.

This does not mean that every symptom-free person has heart disease. It means that the absence of chest pain alone cannot be used to rule out a cardiovascular problem, particularly in people with known risk factors.

Changes from a person’s normal routine may be significant

A single episode of tiredness after poor sleep, intense work or emotional stress is not necessarily a sign of heart disease.

What matters more is a persistent or recurring change compared with the person’s usual level of functioning.

Warning signs may include:

• Needing to stop while climbing stairs that were previously manageable,
• Becoming unusually tired during a familiar walk,
• Completing household tasks more slowly,
• Experiencing shortness of breath during ordinary activity,
• Feeling pressure, tightness or unexplained discomfort in the chest,
• Developing intermittent palpitations,
• Feeling dizzy or close to fainting,
• Avoiding activities that previously caused no difficulty.

People sometimes attribute these changes to aging, stress, lack of sleep or a demanding schedule. Those explanations may be correct, but repeated or worsening symptoms should not automatically be dismissed.

Fatigue and breathlessness can also result from anemia, thyroid disease, lung conditions, infections, anxiety, poor sleep or reduced physical fitness. A medical assessment is therefore needed to identify the actual cause.

Different heart conditions can produce different symptoms

There is no single symptom pattern that applies to every cardiovascular disease.

Narrowing of the coronary arteries may cause classic chest pain in some people. In others, it may appear mainly as reduced stamina, unusual fatigue, breathlessness or a vague pressure during physical activity.

Heart valve disease may gradually lead to shortness of breath, slower movement and difficulty completing daily activities. Because the decline can be gradual, the patient may adapt by reducing physical effort and may not recognize the progression.

Abnormal heart rhythms may cause a racing, pounding, fluttering or irregular heartbeat. Palpitations can last only a few seconds or recur unpredictably. They may be accompanied by weakness, dizziness, breathlessness or fainting.

Some rhythm disorders may produce no noticeable symptoms and are detected during a routine electrocardiogram or physical examination.

Enlargement of the aorta, the main artery carrying blood from the heart, can also remain silent and may be found only when imaging is performed for another medical reason.

For this reason, clinicians evaluate symptoms together with age, medical history, family history and cardiovascular risk factors rather than relying on one complaint alone.

People with cardiovascular risk factors should be more cautious

Certain conditions and lifestyle factors increase the likelihood of heart and vascular disease.

People may face a higher risk if they have:

• A family history of heart disease at an early age,
• High blood pressure,
• Diabetes,
• High cholesterol,
• A history of smoking,
• Obesity or excess weight,
• A physically inactive lifestyle,
• Increasing age,
• Long-term medical conditions that are not well controlled.

Those who have already been diagnosed with heart disease, undergone stent placement or heart surgery, or been told they have a heart valve problem should not skip scheduled follow-up appointments simply because they feel well.

In some cardiovascular conditions, treatment decisions are based not only on symptoms but also on changes in the structure and function of the heart.

A patient may feel relatively normal while an imaging study shows that a valve problem, heart chamber enlargement or aortic dilation has progressed. Regular monitoring can help clinicians determine the appropriate time for treatment.

Heart evaluations should be personalized

A cardiovascular checkup should not be viewed as an identical package of tests for every person.

The assessment should be planned according to the patient’s age, symptoms, family history, previous diagnoses and individual risk factors.

The first stage may include a detailed medical history, physical examination, blood pressure measurement and selected blood tests.

An electrocardiogram may be used to assess the heart rhythm. Echocardiography can examine the heart’s chambers, pumping function and valves.

Depending on the findings, a physician may recommend an exercise stress test, ambulatory rhythm monitoring such as a Holter monitor, or more advanced imaging.

Testing every person with every available method is not considered an appropriate approach. The purpose is to identify meaningful risk, avoid unnecessary procedures and select the right test at the right time.

Patients can support the evaluation by noting when symptoms began, how long they last, whether they occur during exertion and whether they are accompanied by dizziness, pain, sweating or breathlessness.

A list of current medications and previous medical reports can also help the clinician assess intermittent symptoms more effectively.

Do not delay assessment when symptoms are new or worsening

New or progressively worsening shortness of breath, discomfort during exertion, recurrent palpitations, fainting or swelling in the feet and ankles should be medically assessed without unnecessary delay.

These findings do not always indicate heart disease, but they may require examination to rule out an important cardiovascular cause.

Emergency assessment may be necessary when a person develops:

• Sudden or severe chest pain,
• Pressure or discomfort lasting several minutes or returning repeatedly,
• Sudden shortness of breath,
• Fainting or loss of consciousness,
• Cold sweating with marked discomfort,
• Pain spreading to the arm, back, neck, jaw or upper abdomen,
• Severe weakness, nausea or dizziness accompanying chest symptoms.

Heart attack symptoms are not always dramatic from the beginning. Some people experience pressure, unusual fatigue, nausea, shortness of breath or discomfort rather than intense pain.

Seeking urgent help is especially important when symptoms are sudden, severe or different from anything the person has experienced before.

Recognizing cardiovascular warning signs means paying attention not only to pain, but also to small and persistent changes in ordinary life.

Walking more slowly, needing more rest or losing the ability to perform familiar activities may appear minor. When these changes persist or worsen, however, they should be discussed with a healthcare professional.

Early recognition can help identify risk factors, begin preventive measures and plan treatment before the condition becomes more serious.
