Every year in Sri Lanka, patients die from cardiac events that could have been survived had they – or those around them – recognised what was happening earlier and acted faster. Not because emergency care was unavailable. Not because the condition was untreatable. But because the warning signs were dismissed, delayed, or misunderstood.
Heart disease rarely arrives without warning. In the majority of cases, there are signals – some dramatic, some subtle – that the heart is under stress, that blood flow is compromised, or that the heart’s rhythm has become dangerously abnormal. Knowing what those signals look like, and understanding which ones demand immediate action, can make the difference between survival and a preventable death.
This guide is written for Sri Lankan patients and their families. It covers the key warning signs of heart disease, explains what each signal may indicate, and makes clear which symptoms require emergency response – not a wait-and-see approach.
Why Warning Signs Matter
Cardiovascular disease is the leading cause of death in Sri Lanka, accounting for approximately 30 percent of all deaths. A significant proportion of these deaths occur outside hospital, before the patient reaches emergency care – often because symptoms were not recognised as cardiac, or because the patient delayed seeking help.
The two most critical conditions in which early recognition and rapid action save lives are:
- Acute myocardial infarction (heart attack) – in which a blocked coronary artery causes heart muscle to die at a rate of approximately 1.9 million cells per minute. Time to treatment is directly linked to the amount of heart muscle saved
- Sudden cardiac arrest – in which a life-threatening arrhythmia (ventricular fibrillation) causes the heart to stop pumping effectively. Survival falls by approximately 10 percent for every minute without defibrillation
Beyond these acute emergencies, earlier recognition of chronic heart disease symptoms – breathlessness on exertion, ankle swelling, unexplained fatigue, palpitations – allows diagnosis and treatment before the condition deteriorates to the point of crisis.
The Most Important Heart Disease Symptoms
The following sections cover each of the key warning signs in detail – what they feel like, what they may indicate, and what action is appropriate.
Chest Pain and Chest Discomfort
Chest pain is the symptom most people associate with heart disease, and rightly so. But the character of cardiac chest pain is often different from what patients expect – and this mismatch leads to dangerous dismissal.
What Cardiac Chest Pain Feels Like
Cardiac chest pain is classically described as:
- A pressure, heaviness, or tightness in the centre or left side of the chest
- A squeezing or crushing sensation – as if a heavy weight is sitting on the chest
- A burning feeling across the chest
- Pain that spreads to the left arm, right arm, both arms, the jaw, the neck, the back, or the upper abdomen
- Pain that comes on with physical activity and is relieved by rest (angina) – or pain that comes on at rest or with minimal activity (unstable angina or heart attack)
What Cardiac Chest Pain Does Not Always Feel Like
This is critically important: cardiac chest pain does not always feel like the dramatic, crushing central chest pain portrayed in films. It can be:
- A mild ache or dull discomfort that the patient describes as not particularly severe
- A feeling of fullness or indigestion
- Discomfort limited to the jaw, arm, or back without any sensation in the chest itself
- A pressure that builds gradually rather than arriving suddenly
When to Treat Chest Pain as Cardiac Until Proven Otherwise
Any chest discomfort that:
- Occurs with physical activity and is relieved by rest
- Lasts more than a few minutes
- Is accompanied by breathlessness, sweating, nausea, or dizziness
- Radiates to the arm, jaw, neck, or back
- Occurs at rest in someone with known or suspected heart disease
…should be treated as potentially cardiac until a medical assessment has confirmed otherwise.
Do not drive yourself. Do not wait to see if it passes. Seek emergency medical attention immediately.
Breathlessness
Breathlessness – the sensation of being unable to get enough air, or of breathing requiring more effort than it should – is one of the most common and most frequently underestimated symptoms of heart disease.
Breathlessness as a Cardiac Symptom
The heart and lungs work in close partnership. When the heart’s pumping function is impaired – by coronary artery disease, heart failure, valve disease, or cardiomyopathy – fluid can accumulate in the lungs, making them stiffer and harder to expand. The result is breathlessness.
Cardiac breathlessness presents in several characteristic patterns:
- Exertional breathlessness – becoming more breathless than expected with activities that previously caused no difficulty. Walking up a flight of stairs, walking uphill, or carrying shopping that previously caused no difficulty now causes significant breathlessness
- Orthopnoea – breathlessness that worsens when lying flat and is relieved by sitting or standing up. Patients may find themselves sleeping propped up on multiple pillows. This is a hallmark symptom of heart failure
- Paroxysmal nocturnal dyspnoea – sudden breathlessness that wakes the patient from sleep, often accompanied by a feeling of suffocation. The patient typically needs to sit up or stand by an open window to get relief. This symptom almost always warrants urgent medical assessment
- Breathlessness at rest – severe or worsening cardiac conditions can cause breathlessness even without physical activity
When Breathlessness Requires Urgent Attention
- Sudden onset of severe breathlessness at rest
- Breathlessness accompanied by chest pain
- Breathlessness that has developed over days and is progressively worsening
- Breathlessness that wakes you from sleep
- Breathlessness accompanied by pink or frothy sputum – a sign of acute pulmonary oedema requiring emergency intervention
Palpitations and Irregular Heartbeat
Palpitations – an awareness of the heart beating, whether rapidly, irregularly, or with unusual force – are one of the most common symptoms that leads patients to seek cardiac evaluation.
Types of Palpitations
- Racing heart – a sudden episode in which the heart beats much faster than normal. This can represent supraventricular tachycardia, atrial flutter, atrial fibrillation, or in more serious cases, ventricular tachycardia
- Irregular heartbeat – a feeling that the heart is beating out of rhythm, with beats that seem to skip or come too early. Irregular heartbeat is the hallmark of atrial fibrillation – the most common sustained cardiac arrhythmia
- Forceful beats – a sensation of the heart thumping or pounding, even when the rate is not particularly fast. Can be associated with anxiety, anaemia, or cardiac conditions
When Palpitations Require Prompt Evaluation
- Palpitations accompanied by breathlessness, chest pain, or dizziness
- Palpitations that cause near-fainting or fainting
- Palpitations that start and stop suddenly, lasting minutes to hours
- Irregular palpitations that are persistent rather than occasional
- Palpitations in a patient with known or suspected heart disease
An ECG during the episode is the most useful investigation for characterising palpitations. If the episode has passed by the time a patient reaches a doctor, a Holter monitor – a portable ECG worn for 24 to 48 hours or longer – may be needed to capture the rhythm during a subsequent episode.
Atrial fibrillation in particular deserves attention beyond its symptoms. As discussed in our article on heart rhythm disorders and atrial fibrillation for Sri Lankan patients, AF significantly increases the risk of stroke even when it causes no symptoms – making early diagnosis and treatment critical.
Dizziness, Lightheadedness, and Fainting
Cardiac Causes of Dizziness and Fainting
The brain requires a continuous and adequate supply of oxygenated blood to function normally. When the heart fails to maintain this supply – either because it is pumping too slowly, too quickly, or too inefficiently – the result can range from dizziness and near-fainting to complete loss of consciousness.
Cardiac causes of dizziness and fainting include:
- Bradyarrhythmias – abnormally slow heart rates or pauses in the heartbeat that reduce cerebral blood flow. A heart rate of 30 to 40 beats per minute produces inadequate cardiac output for normal brain function in most people
- Tachyarrhythmias – very rapid heart rates can be so inefficient that cardiac output falls despite the high rate
- Aortic stenosis – severe narrowing of the aortic valve reduces the heart’s ability to increase cardiac output with exertion. Fainting during or after physical activity in a patient with aortic stenosis is a particularly serious warning sign
- Hypertrophic obstructive cardiomyopathy (HOCM) – a condition in which the heart muscle is abnormally thick, obstructing blood flow from the heart. Fainting during exertion in a young patient should always raise suspicion of HOCM
- Vasovagal syncope – a reflex-mediated faint triggered by pain, emotional distress, prolonged standing, or heat. Generally benign, but cardiac causes must be excluded before this diagnosis is made
When Fainting Requires Emergency Assessment
- Fainting during or immediately after physical exertion – always requires urgent cardiac assessment
- Fainting without warning – sudden loss of consciousness without preceding dizziness suggests a cardiac rather than vasovagal cause
- Fainting associated with chest pain or palpitations
- Fainting in a patient with known heart disease
- Fainting that occurs more than once
- Fainting in a young person, particularly during or after exercise
Swelling of the Ankles and Legs
Swelling of the ankles and feet (oedema) is a common symptom with multiple possible causes – but heart failure is one of the most important to exclude.
How Heart Failure Causes Ankle Swelling
When the right side of the heart is not pumping effectively, pressure backs up in the veins returning blood from the body. This increased venous pressure causes fluid to leak out of the blood vessels and accumulate in the tissues, particularly in the ankles and feet – the lowest points where gravity draws the fluid.
Characteristics of cardiac oedema:
- Typically worse in the evening after a day of standing or walking
- Improves overnight when the patient is lying flat and gravity is no longer pulling fluid into the ankles
- Pitting oedema – pressing a finger into the swollen tissue leaves an indentation that persists for several seconds
- May progress up the legs as heart failure worsens
- Often accompanied by breathlessness and fatigue
When Ankle Swelling Requires Cardiac Assessment
- Ankle swelling accompanied by breathlessness
- Ankle swelling that is progressive or worsening
- Ankle swelling in a patient with known or suspected heart disease
- Ankle swelling that does not resolve after a night of rest
- Swelling that extends above the ankles into the lower legs
Unexplained Fatigue
Fatigue is one of the most non-specific symptoms in medicine – it has hundreds of possible causes. But persistent, unexplained fatigue that is disproportionate to the patient’s level of activity and that has developed over weeks or months without an obvious cause warrants cardiac evaluation, particularly in patients with risk factors for heart disease.
How Heart Disease Causes Fatigue
When cardiac output is reduced – whether due to heart failure, significant valve disease, severe anaemia from cardiac causes, or arrhythmia – the muscles and organs of the body receive less oxygen-rich blood than they need for normal function. The result is a pervasive sense of tiredness that does not resolve with rest and that limits the patient’s capacity for normal daily activities.
Fatigue as an Atypical Heart Attack Symptom
Fatigue – often described as an overwhelming, unusual tiredness that is unlike normal tiredness – can be a presenting symptom of a heart attack, particularly in women and in elderly patients. This is discussed in more detail in the section on symptoms in women below.
Symptoms That Are Easily Dismissed But Should Not Be
Several cardiac symptoms are commonly dismissed because they seem trivial, intermittent, or explicable by other causes:
Jaw Pain or Toothache
Pain referred to the jaw – particularly the lower jaw – can be the sole presenting symptom of a heart attack. Patients who develop unexplained jaw pain or ache in the context of other risk factors, or who develop it during or after exertion, should seek urgent medical assessment rather than attributing it to dental causes.
Upper Abdominal Pain or Indigestion
The lower heart and diaphragm share nerve pathways that can cause cardiac pain to be felt as upper abdominal discomfort, epigastric pain, or indigestion. Patients who develop what seems like indigestion during physical activity, or indigestion that is accompanied by sweating or breathlessness, should seek urgent assessment.
Arm Pain or Shoulder Pain Without Obvious Cause
Pain in the left arm – particularly radiating from the chest or shoulder into the arm – is a classic cardiac symptom. But right arm pain, or bilateral arm pain, can also occur. Unexplained arm or shoulder pain that develops with exertion or at rest in a patient with cardiac risk factors warrants evaluation.
Cold Sweats Without Obvious Cause
Profuse sweating – particularly cold, clammy sweating – that occurs without physical exertion or obvious cause is a significant warning sign. It reflects the body’s stress response to severe pain, cardiovascular compromise, or both. In the context of any of the symptoms described above, cold sweating should prompt immediate emergency response.
Symptoms in Women: Why They Can Be Different
Heart disease in women can present differently from the classic male presentation of severe crushing central chest pain. This difference in presentation contributes to delayed diagnosis and worse outcomes in women.
Women are more likely to experience:
- Breathlessness as the dominant or sole presenting symptom of a heart attack
- Nausea, vomiting, or abdominal discomfort
- Unusual fatigue – described as an overwhelming tiredness unlike any they have felt before
- Back pain or jaw pain without significant chest pain
- A more gradual onset of symptoms rather than a sudden dramatic event
These atypical presentations mean that women are more likely to dismiss their symptoms, and are more likely to have their symptoms dismissed by healthcare providers, leading to a longer time to diagnosis and treatment.
Sri Lankan women with cardiovascular risk factors – diabetes, hypertension, a family history of heart disease, or a history of rheumatic heart disease – should be aware that a heart attack or significant cardiac event may not feel like the classical dramatic chest-clutching presentation. Any new and unexplained combination of breathlessness, fatigue, nausea, back pain, or jaw pain warrants prompt medical assessment.
When to Call for Emergency Help Immediately
The following symptoms require emergency medical attention without delay. Do not drive yourself. Call for an ambulance or have someone drive you to the nearest emergency department immediately:
- Chest pain or pressure lasting more than a few minutes, particularly if it radiates to the arm, jaw, neck, or back
- Sudden severe breathlessness at rest
- Sudden loss of consciousness or collapse
- Sudden onset of severe sweating, nausea, and breathlessness together
- A very rapid, irregular, or extremely slow heart rate associated with dizziness or near-fainting
- Sudden weakness or numbness down one side of the body, sudden difficulty speaking, or sudden vision loss – these are stroke symptoms and require the same emergency response as a heart attack
The critical message: if you are uncertain whether your symptoms are cardiac, seek emergency assessment and let the doctors rule it out. The risk of a false alarm is infinitely lower than the risk of dismissing a genuine cardiac emergency.
What to Do While Waiting for Help
If you or someone with you is experiencing symptoms that may be a heart attack:
- Sit or lie in a comfortable position – do not walk around unnecessarily
- Loosen any tight clothing
- If the person is conscious and not allergic to aspirin, 300 mg of aspirin (chewed, not swallowed whole) can be given while waiting for emergency help to arrive. Aspirin helps prevent further clot formation in the coronary artery
- Do not give food or water
- If the person loses consciousness and stops breathing normally, cardiopulmonary resuscitation (CPR) should be started immediately if the person performing it is trained to do so. Hands-only CPR – continuous chest compressions at a rate of 100 to 120 per minute – is better than no CPR
- If an automated external defibrillator (AED) is available nearby, use it as instructed. AEDs are designed for use by untrained bystanders and provide step-by-step voice instructions
After the Emergency: What Comes Next
For patients who have experienced an acute cardiac event and received emergency treatment, the period after the emergency is critical for:
- Understanding what happened and what the underlying cardiac diagnosis is
- Receiving the appropriate treatment to prevent recurrence – medication, further procedures (stenting, surgery, device implantation), or both
- Addressing the risk factors that contributed to the event
- Cardiac rehabilitation – a structured programme of exercise, education, and risk factor management that significantly reduces the risk of recurrence
For Sri Lankan patients who have had an acute cardiac event and have been discharged from hospital with a diagnosis requiring further specialist intervention – coronary revascularisation, valve surgery, device implantation – and who face a waiting period before that intervention is available locally, accessing timely specialist assessment and treatment at Amrita Hospitals in Kochi is a practical and well-supported option.

Frequently Asked Questions
How do I know if my chest pain is cardiac or just indigestion? This question is addressed specifically in our article on heart attack vs heartburn. The short answer is: when in doubt, seek medical assessment. The features that increase the likelihood of a cardiac cause include pain on exertion, radiation to the arm or jaw, accompanying breathlessness or sweating, and a background of cardiac risk factors. Indigestion is usually related to eating, relieved by antacids, and not accompanied by breathlessness or sweating.
Can a heart attack happen without chest pain? Yes. Particularly in women, elderly patients, and patients with diabetes, heart attacks can occur without prominent chest pain. Breathlessness, fatigue, nausea, jaw pain, back pain, or simply a profound sense that something is wrong can be the presenting features. Any unexplained combination of these symptoms warrants urgent assessment.
What should I do if I have palpitations that come and go? Keep a diary of when they occur, how long they last, and what they feel like. Seek a GP or cardiologist appointment to discuss them – do not assume they are harmless. An ECG and possibly a Holter monitor will likely be recommended. If palpitations are accompanied by dizziness, breathlessness, or chest pain, or if they are very rapid or irregular and last more than a few minutes, seek urgent medical assessment rather than waiting for a routine appointment.
Are there any heart disease symptoms specific to Sri Lankan patients? The symptoms of heart disease are not ethnically specific – the same warning signs apply across all populations. However, certain risk factors are particularly prevalent in Sri Lanka, including a high rate of rheumatic heart disease, high rates of diabetes and hypertension, and the specific practice of betel and areca nut chewing which carries cardiovascular risk. Sri Lankan patients with these risk factors should have a lower threshold for seeking cardiac evaluation when symptoms arise.
How quickly should I seek help for cardiac symptoms? For any symptoms that may represent a heart attack or acute cardiac emergency (chest pain, severe breathlessness, collapse, very rapid or irregular heartbeat with dizziness), seek emergency help immediately – within minutes, not hours. For non-urgent symptoms that have developed gradually (ankle swelling, increasing exertional breathlessness, persistent palpitations), arrange a medical appointment within days to weeks, not months.
Conclusion
Heart disease warns before it strikes – in most cases, and in most people. The warning signs described in this guide are the body’s signals that something is wrong and that attention is needed.
For Sri Lankan patients, the two most important actions are straightforward: know the warning signs, and take them seriously. A symptom dismissed or delayed can become a life-threatening emergency that could have been prevented.
If you or a family member have experienced any of the symptoms described in this guide, the next step is a cardiac assessment. Amrita Info Centre Sri Lanka can help coordinate that assessment, whether locally or at Amrita Hospitals in India, with the speed and clarity the situation requires.
