  • Spot a stroke with BE FAST: Balance, Eyes, Face, Arm, Speech, Time to call 999.
  • Heart attack signs include chest pain or pressure, pain spreading to the arm, jaw or back, breathlessness and sweating. Women, older people and people with diabetes may have no chest pain.
  • Call 999, or 112 from a mobile, and note the time symptoms started. Clot-busting treatment for stroke must start within 4.5 hours.
  • Don’t give aspirin for a suspected stroke. For a suspected heart attack, take aspirin only if the 999 operator or a doctor tells you to.

Why minutes matter

Ischaemic heart disease is Malaysia’s leading cause of death. It caused 17,421 deaths in 2024, 13% of medically certified deaths, according to the Department of Statistics. Stroke is consistently among the top three causes, and is estimated to affect more than 50,000 Malaysians a year.

Malaysians also have heart attacks young. In the national heart registry for 2020–2021, the average age at admission with a heart attack or unstable angina was 58.5 years, and a quarter of patients were under 50.

Most strokes and heart attacks are caused by a blocked artery. In a stroke, about 1.9 million brain cells die every minute the blockage continues. Yet in a Malaysian stroke study, patients took a median of seven hours or more to reach hospital, too late for the most effective treatments.

Stroke warning signs: BE FAST

A stroke comes on suddenly. Use BE FAST to check, or its Malay version, PeRMATA:

BE FASTWhat to look forPeRMATA
BalanceSudden dizziness, loss of balance or trouble walkingPening
EyesSudden blurred, double or lost visionRabun
FaceOne side of the face droops. Ask them to smile.Muka herot
ArmWeakness or numbness in one arm or leg. Ask them to raise both arms.Angkat tangan
SpeechSlurred speech, or difficulty speaking or understandingTutur
TimeCall 999 now, and note the time symptoms startedAngkat telefon

Call 999 even if the symptoms go away after a few minutes. This can be a “mini-stroke” (transient ischaemic attack), which is a warning that a major stroke may follow.

Heart attack warning signs

  • Chest pain, pressure, tightness or squeezing, lasting more than a few minutes or coming and going
  • Pain spreading to one or both arms, the neck, jaw, back or upper stomach
  • Shortness of breath
  • Cold sweat, nausea or vomiting, or light-headedness

Women, older people and people with diabetes are more likely to have a heart attack without obvious chest pain. They may feel only breathlessness, nausea, unusual tiredness or discomfort in the back or jaw. Don’t dismiss these as indigestion or “angin”, especially if you have risk factors.

What to do while you wait for help

  1. Call 999 (or 112 from a mobile). Say you suspect a stroke or heart attack and give the exact address.
  2. Note the time symptoms started, or when the person was last seen well. Doctors need this to decide on treatment.
  3. Keep the person still, sitting or lying in a comfortable position, and loosen tight clothing.
  4. For a suspected stroke: give nothing to eat or drink, as swallowing may be affected. Don’t give aspirin. Some strokes are caused by bleeding, which aspirin can make worse, and only a brain scan can tell.
  5. For a suspected heart attack: take aspirin only if the 999 operator or a doctor tells you to, and not if you are allergic to it. Use your own heart medicines, such as a GTN spray, as your doctor has advised.
  6. If the person collapses and isn’t breathing normally, start hands-only CPR: push hard and fast in the centre of the chest, about twice a second, and keep going until help arrives. Ask someone to find an AED (defibrillator) if one is nearby.
  7. Gather the person’s IC and a list of their medicines.
Don’t go to a GP clinic

A GP clinic can’t give clot-busting treatment, and going there first loses precious time. Call 999. If you can’t wait for an ambulance, have someone else drive you straight to a hospital emergency department. Don’t drive yourself.

Ambulance response times

Ambulance response is a known weak spot. In 2025, only 34.01% of the most urgent (Priority 1) cases were reached within the 15-minute target, against a goal of 50%, the Health Minister told Parliament in October 2026. Budget 2027 funds 400 new ambulances for Ministry of Health hospitals.

Calling 999 is still the right first step, because it gets trained help on the way. If the ambulance is delayed and the person is stable enough to travel, a family member can drive them to the nearest hospital emergency department.

Treatments that depend on time

TreatmentWhat it doesTime window
Thrombolysis (stroke)A clot-busting drug through a dripWithin 4.5 hours of symptoms starting
Thrombectomy (stroke)A thin tube removes a large clot from a brain arteryBest within 6 hours; up to 24 hours in selected patients
Primary angioplasty (heart attack)A balloon and stent reopen the blocked heart artery in a cath labTarget: within 90 minutes of arriving at hospital
Thrombolysis (heart attack)A clot-busting drug, when angioplasty isn’t quickly availableTarget: within 30 minutes of arriving at hospital

Malaysian hospitals are getting faster. In the national heart registry for 2020–2021, the median time from arrival to angioplasty was 69.5 minutes, and 63.6% of patients were treated within the 90-minute target. The biggest delay is usually before the patient reaches hospital.

Hospitals in and around Kuala Lumpur

In an emergency, go to the nearest hospital emergency department, or where the ambulance takes you. Every emergency department can assess you, start treatment and transfer you if a specialist procedure is needed.

Stroke: these government and university hospitals in the Klang Valley have stroke units and can perform thrombectomy, according to the international Angels Initiative stroke network:

  • Hospital Kuala Lumpur (HKL)
  • Hospital Sungai Buloh
  • University Malaya Medical Centre (UMMC)
  • Hospital Canselor Tuanku Muhriz (HCTM), UKM, Cheras

HCTM and Hospital Sultan Abdul Aziz Shah (UPM) in Serdang are certified as advanced stroke centres by the World Stroke Organization.

Heart attack: the National Heart Institute (IJN) runs a 24-hour heart attack centre for emergency angioplasty, and Hospital Serdang has a large cardiac centre. Major university hospitals and many private hospitals in the Klang Valley also have cath labs and stroke services.

If you have heart disease or have had a stroke, ask your doctor now which hospital you should go to in an emergency, and save the details in your phone.

Lower your risk

Most strokes and heart attacks are linked to risk factors you can check and treat. Among Malaysian adults, according to the National Health and Morbidity Survey 2023:

  • 29.2% have high blood pressure, and 11.9% have it without knowing.
  • 15.6% have diabetes and 33.3% have high cholesterol.
  • 19.0% smoke, and 29.9% are physically inactive.

Check your blood pressure at least once a year from age 18, and your blood sugar and cholesterol from age 30. Many people qualify for free health screening. You can also check your blood pressure at home. Take medicines as prescribed, stop smoking, and aim for 150 minutes of activity a week.

Check your risk at a GP clinic

For prevention, not emergencies: a GP can check your blood pressure, blood sugar and cholesterol, and manage them over time. For stroke or heart attack symptoms, call 999. Our directory lists GP clinics across Kuala Lumpur, Selangor and other states.
