In hardworking Singapore, cardiovascular diseases like heart attack and stroke are rising rapidly. Cases of heart attack are projected to nearly triple by 2050, with many linked to heart artery blockage. Understanding the difference between these two emergencies is crucial, as each requires fast, specific treatment. A heart attack affects the heart; a stroke impacts the brain, but both can be fatal if ignored.
At Gerard Leong Cardiology Clinic, we’re committed to early detection, prevention, and patient education. This guide helps you recognise key symptoms, causes, and recovery paths to protect your heart and brain health.
Key Takeaways
- A heart attack occurs when a heart artery blockage blocks blood flow to the heart muscle, causing chest pain, shortness of breath, and nausea. Immediate treatment is critical to prevent heart damage.
- A stroke happens when blood flow to the brain is disrupted, either by a clot or bleeding, leading to sudden weakness, confusion, or loss of balance. Recognising FAST symptoms can save lives.
- Early diagnosis through ECG, blood tests, and imaging is vital for both heart attacks and strokes, enabling timely treatment and better recovery outcomes. Regular screening at cardiology clinics helps detect risks like heart artery blockage early.
Key Differences: Stroke vs. Heart Attack
A stroke occurs when there is a sudden interruption in the brain’s blood supply, either due to a blockage or a rupture in a blood vessel. Ischemic strokes, the most common type, result from a blood clot obstructing a vessel, while hemorrhagic strokes occur when a weakened blood vessel bursts, causing bleeding in the brain. Both types can lead to significant brain cell damage and loss of function in the affected area.
On the other hand, a heart attack is caused by a blockage in the arteries that supply blood to the heart. This heart artery blockage, often due to plaque buildup, prevents oxygen-rich blood from reaching the heart muscle, leading to damage or death of the tissue.
For easier understanding, here is a comparison table:
Category | Stroke | Heart Attack |
Affected Organ | Brain: caused by a blood clot or bleeding | Heart: typically caused by a heart artery blockage |
Key Symptoms | Sudden numbness, confusion, blurred vision, loss of balance | Chest pain, shortness of breath, arm/jaw pain, nausea |
Onset and Timing | Usually sudden and without warning | May build up from minutes to hours |
Emergency Response | Call 995 immediately, note the time symptoms started | Chew aspirin (if not allergic), call 995 |
Recognising early signs of these conditions is critical, as prompt treatment can improve outcomes and reduce long-term damage.
Symptoms: How a Stroke and Heart Attack Differ
Stroke Symptoms
A stroke is a medical emergency that occurs when blood flow to the brain is interrupted, depriving brain cells of oxygen and nutrients. Therefore, time is of the essence. Recognising stroke symptoms and acting immediately can mean the difference between full recovery and lifelong disability. To know if a person is having a stroke, remember the acronym “FAST”.
- F – Face: Ask the person to smile. Does one side of the face droop or appear numb?
- A – Arms: Ask the person to raise both arms. Does one arm drift downward or appear weak?
- S – Speech: Is the person’s speech slurred, difficult to understand, or repeated?
- T – Time: Call 995 (or your local emergency number) immediately if you notice any of these signs. Time is critical in stroke treatment.
Aside from the ones mentioned above, you must watch for the following symptoms:
- Sudden numbness or weakness, particularly on one side of the body.
- Sudden loss of vision, particularly in one eye.
- Confusion, dizziness, or trouble walking.
Heart Attack Symptoms
In Singapore, heart attacks remain a top cause of mortality, particularly among adults with undiagnosed or uncontrolled cardiovascular risk factors. The danger lies not only in the event itself but in how often symptoms are ignored or misunderstood.
Here are the common symptoms to watch for:
- Chest pain or discomfort may feel like pressure, squeezing, or fullness.
- Shortness of breath, even when resting.
- Nausea, lightheadedness, or dizziness.
- Pain in the back, jaw, neck, or stomach, sometimes spreading to the shoulders and arms.
- Some individuals, especially women, diabetics, and older adults, may experience atypical symptoms such as unusual fatigue, nausea, or no chest pain at all.
At Gerard Leong Cardiology Clinic, we advocate for early screening and lifestyle modification. Heart attacks and strokes are preventable. Your first symptom should never be your last warning. Be proactive. Know your numbers. Get checked.
Causes of Stroke vs. Heart Attack
What Causes a Stroke?
Stroke risk is often tied to lifestyle and medical conditions. In Singapore, the most common contributors include:
- High blood pressure is the leading cause of both stroke types.
- Blood clots are often triggered by poor circulation or artery disease.
- Atrial fibrillation or irregular heartbeat can lead to clot formation.
- Smoking and obesity both elevate cardiovascular risk dramatically.
Heart Attack Causes
The root cause is often coronary artery disease (CAD) or the gradual narrowing of arteries due to plaque buildup. This heart artery blockage can rupture and form a clot, stopping blood flow entirely. Contributing risk factors include:
- A blockage in the coronary arteries is often caused by plaque buildup, which can result from high cholesterol, smoking, poor diet, and other factors.
- Conditions such as hypertension and diabetes increase the risk by damaging blood vessels and promoting atherosclerosis.
- Another risk factor is a sedentary lifestyle and chronic stress.
Diagnosis: How Doctors Identify a Stroke or Heart Attack
In time-critical conditions like heart attacks and strokes, rapid and accurate diagnosis is essential, not just for survival, but for minimising long-term damage. In Singapore, access to modern diagnostic tools has significantly improved outcomes, especially when patients seek help early.
Stroke Diagnosis
For strokes, immediate brain imaging is crucial:
- CT scans or MRIs to detect brain damage or if the stroke is ischaemic (clot) or haemorrhagic (bleed)..
- Physical exams to check neurological function.
Heart Attack Diagnosis
When a heart attack is suspected, doctors rely on:
- An electrocardiogram (ECG) is used to detect abnormal heart rhythms
- Blood tests to detect markers of heart muscle damage.
- Angiography is used to examine blood flow in the coronary arteries.
A quick diagnosis ensures that appropriate treatments are initiated as soon as possible.
Treatment Options for Stroke vs. Heart Attack
Surviving a heart attack or stroke is only the beginning. True recovery depends on timely treatment, long-term follow-up, and lifestyle change. In Singapore, where access to world-class cardiovascular and neurological care is growing, early intervention can mean the difference between independence and lifelong complications.
Stroke Treatments
Time is even more critical in stroke management:
- For ischemic strokes, clot-busting medications like TtPA (tissue plasminogen activator) may help dissolve clots in eligible patients
- Surgery to remove clots or repair ruptured blood vessels.
- Rehabilitation to regain lost functions such as movement, speech, or cognition.
Heart Attack Treatments
In most heart attack cases, especially those caused by a heart artery blockage, the priority is to restore blood flow. This is done through:
- Emergency medications, such as blood thinners, beta-blockers, and cholesterol-lowering drugs, are used to dissolve clots, reduce pain or dilate blood vessels.
- Angioplasty to open blocked arteries or bypass surgery to reroute blood flow.
- Long-term lifestyle changes, including a healthier diet, increased physical activity, and possibly medications to prevent further blockages.
Recovery isn’t just physical. It also includes emotional and mental recoveries. At Gerard Leong Cardiology Clinic, we work closely with allied professionals to support each patient’s full return to life. Recovery is possible, but it starts with getting the right help, fast.
Prevention: How to Protect Yourself from Both Stroke and Heart Attack
Preventing heart attacks and strokes can help you protect your health. The following preventive measures are key:
- Maintaining a healthy diet rich in fruits, vegetables, and whole grains, and moderation in other foods.
- Regular physical activity, such as walking, swimming, or cycling.
- Quitting smoking significantly reduces the risk of cardiovascular disease, including plaque buildup in the arteries.
- Managing stress through relaxation techniques, like meditation or yoga.
- Having regular checkups with your doctor.
Recovery and Rehabilitation After a Stroke or Heart Attack
Stroke Recovery
Recovery after a stroke can involve a combination of physical therapy, speech therapy, and occupational therapy to regain lost abilities and improve daily functioning. This is done under supervision of your specialists.
Heart Attack Recovery
After a heart attack, rehabilitation often involves cardiac rehabilitation, lifestyle changes like diet and exercise, and medications to prevent further complications.
Both recovery processes require a long-term commitment to maintaining healthy habits and monitoring health to avoid complications.

Frequently Asked Questions
Is a heart attack more dangerous than a stroke?
Both a heart attack and a stroke are medical emergencies with life-threatening consequences. A heart attack damages the heart muscle, while a stroke affects the brain. The danger depends on severity, speed of treatment, and overall health, but both require immediate medical attention to prevent permanent damage or death.
Can stress cause heart attacks or strokes?
Yes. Chronic stress can elevate blood pressure, increase inflammation, and contribute to heart artery blockage, all of which raise the risk of heart attacks and strokes. Stress also encourages unhealthy coping habits like smoking, overeating, or alcohol use, which compound cardiovascular risk over time.
What should I do if I suspect a heart attack in Singapore?
Call 995 immediately. While waiting for help, have the person sit down and chew an aspirin, unless allergic, to reduce clot formation. Do not delay. In heart attack cases, early intervention like angioplasty can be lifesaving, especially within the first 90 minutes.
How is heart artery blockage detected?
Heart artery blockage is diagnosed through tests such as electrocardiograms (ECG), blood tests for troponin, and coronary angiograms, which visually map blood flow in the heart. At Dr. Gerard Leong Cardiology Clinic, we offer advanced diagnostics for early detection and prevention.
What are the long-term effects of a stroke?
Stroke survivors may experience lasting effects like speech difficulties, mobility loss, memory issues, or emotional changes. Recovery depends on the brain area affected and how quickly treatment begins. Rehabilitation, including physical, speech, and occupational therapy, is critical for improving long-term quality of life
