Heart attacks and strokes are medical emergencies requiring immediate treatment
Heart attacks and strokes are medical emergencies that require immediate treatment. Both are life-threatening conditions that can lead to permanent damage, disability, or death if not addressed promptly.
A heart attack occurs when there is an interruption in the normal flow of blood to the heart, causing cells to malfunction and die due to a lack of oxygen-rich blood and nutrients. Common symptoms include sustained, crushing chest pain, difficulty breathing, cold sweats, a racing heart, pain in the left arm, jaw stiffness, and shoulder pain. Women may experience additional or alternative symptoms, such as extreme exhaustion, fatigue, indigestion, or nausea.
A stroke, often referred to as the brain's equivalent of a heart attack, occurs when there is an issue with blood flow to the brain. This can be due to blocked blood vessels or bleeding in the brain, resulting in brain cells dying from oxygen deprivation. Recognizing the signs of a stroke is crucial, as immediate medical attention is critical to preventing permanent damage or death. The acronym BE FAST is a helpful tool to identify the signs:
- Balance: Watch for a sudden loss of balance.
- Eyes: Look for a sudden loss of vision, double vision, or drooping of one or both sides of the face.
- Face: Ask the person to smile and observe for muscle weakness or paralysis on one side.
- Arms: Check for weakness or numbness in one arm by asking the person to raise both arms.
- Speech: Observe if the person has difficulty speaking or understanding speech.
- Time: Act quickly and call for emergency medical assistance.
The quicker treatment is administered for both heart attacks and strokes, the better the chances of recovery without permanent disability or damage. Therefore, it is essential to seek medical help right away if you or someone else is exhibiting any of these symptoms.

Heart attacks are commonly caused by a blockage in the coronary artery
Heart attacks and strokes are serious medical emergencies that require immediate attention. In the case of a heart attack, every minute counts as the heart muscle starts to die due to a lack of blood flow, which can lead to permanent damage or death.
Heart Attacks
The plaque can rupture and form a clot that blocks blood flow, causing a heart attack. During a heart attack, the lack of blood flow results in the death of tissue in the heart muscle. This can lead to permanent heart damage or death if blood flow is not restored quickly.
The most common symptoms of a heart attack include:
- Sustained, crushing chest pain
- Difficulty breathing
- Cold sweats
- A racing heart
- Pain in the left arm, jaw, or shoulder
However, it is important to note that women often experience different symptoms than men. Instead of chest pain, they may feel extreme exhaustion, fatigue, indigestion, or nausea.
The duration of a heart attack is not specified, but it is important to act quickly at the first sign of symptoms. Calling for emergency medical help is crucial, and taking aspirin, if recommended by a healthcare provider, may help reduce heart damage by preventing blood clotting.
Treatment for Heart Attacks
The treatment for heart attacks focuses on restoring blood flow to the affected heart muscle as soon as possible. This can be achieved through medication, surgery, or other procedures. Some common treatments include:
- Supplementary oxygen
- Anti-clotting medications
- Nitroglycerin to relieve chest pain and widen blood vessels
- Thrombolytic (clot-busting) medications
- Anti-arrhythmia medications to address malfunctions in the heart's normal beating rhythm
- Pain medications, such as morphine
- Beta-blockers to slow down the heart rate and aid recovery
- Antihypertensives to decrease blood pressure
- Statins to stabilize plaque and reduce cholesterol

Strokes are caused by a blockage or bleeding in the brain
Strokes and heart attacks are caused by interruptions to the normal flow of blood to the heart or brain. Without access to oxygen-rich blood and nutrients, cells begin to malfunction and die. In the case of strokes, this is specifically due to a blockage or bleeding in the brain.
There are two main types of strokes: ischemic strokes and hemorrhagic strokes. Ischemic strokes are caused by a blockage of an artery or, in rare cases, a vein. They account for about 87% of all strokes. Hemorrhagic strokes, on the other hand, are caused by bleeding and make up about 13% of strokes.
Ischemic strokes occur when a blood vessel supplying the brain becomes blocked or clogged, impairing blood flow. This can be due to a blood clot that develops in the blood vessels inside the brain (thrombotic stroke) or a blood clot or plaque debris that develops elsewhere in the body and travels to the brain through the bloodstream (embolic stroke). Thrombotic strokes are usually seen in older people with high cholesterol, atherosclerosis, or diabetes. Embolic strokes often result from heart disease or heart surgery and occur without warning signs.
Hemorrhagic strokes occur when a blood vessel supplying the brain ruptures and bleeds. This bleeding disrupts normal circulation in the brain, preventing it from getting the blood and oxygen it needs. The bleeding also increases pressure inside the skull, which can compress and damage brain tissue. Hemorrhagic strokes are divided into two main categories: intracerebral hemorrhage, where bleeding occurs from the blood vessels within the brain, and subarachnoid hemorrhage, where bleeding occurs in the subarachnoid space between the brain and the membranes that cover it.
The duration of a stroke can vary. Sometimes, stroke symptoms last for a short time (minutes to hours) and then disappear. These are known as transient ischemic attacks (TIAs) or mini-strokes and can be a warning sign of an impending major stroke. However, even if stroke symptoms don't last long, immediate medical attention is crucial. The longer the delay in getting help, the greater the risk of permanent damage or death.

Heart attack symptoms include chest pain, pressure, lightheadedness, and pain in the arms, neck, jaw, back, or abdomen
A heart attack, or myocardial infarction, occurs when blood flow to the heart is blocked. If blood flow is restricted for too long, usually more than 20 minutes, the heart muscle can be irreversibly damaged. Therefore, it is important to recognise the symptoms of a heart attack and act quickly.
Other symptoms of a heart attack include shortness of breath, cold sweats, nausea, and a rapid or irregular heartbeat. Some people experience feelings of anxiety or impending doom. Women may experience different symptoms, such as extreme fatigue, upper abdominal discomfort, dizziness, and jaw pain.
If you or someone else is experiencing these symptoms, it is important to seek medical help immediately. Do not delay, as quick action can save lives and prevent permanent damage to the body.

Strokes and heart attacks are serious medical emergencies that require immediate attention. Both are caused by interruptions to the normal flow of blood to the heart or brain, which are essential organs. Quick action can prevent deaths and limit permanent damage to the body.
Stroke Symptoms
- Numbness or weakness in the face, arm, or leg, especially on one side of the body.
- Confusion, trouble speaking, or difficulty understanding speech.
- Problems with vision in one or both eyes.
- Dizziness, loss of balance, or lack of coordination.
- A sudden, severe headache with no apparent cause.
- Double vision, drowsiness, nausea, or vomiting.
The F.A.S.T. acronym is a helpful tool to identify and remember the signs of a stroke:
- Face: Is one side of the face drooping or numb? Ask the person to smile and check if their smile is uneven.
- Arm: Is one arm weak or numb? Ask the person to raise both arms and observe if one arm drifts downward.
- Speech: Is the person's speech slurred? Are they unable to speak or hard to understand? Ask them to repeat a simple sentence.
- Time: If you observe any of these symptoms, it's time to call 911 immediately. Note the time when the symptoms first appeared, as it will help healthcare providers determine the best treatment.
Strokes can be ischemic (caused by a clot blocking blood flow to the brain) or hemorrhagic (caused by a burst blood vessel bleeding into or around the brain). Sometimes, stroke symptoms may last only a short time (minutes to hours) and then disappear, which is called a transient ischemic attack (TIA) or mini-stroke. Even in such cases, it is crucial to seek immediate medical attention as it could be a warning sign of a more severe stroke.

Frequently asked questions
The duration of a stroke varies. Some can last just minutes, while others can last hours or even days. The World Health Organization defines a stroke as a clinical syndrome with rapidly developing signs of cerebral dysfunction that last over 24 hours or lead to death. However, even if symptoms last less than 24 hours, it can still be diagnosed as a mild stroke if brain lesions are detected through imaging techniques.
On average, a heart attack lasts around 15 to 20 minutes, with symptoms sometimes lingering beyond this timeframe. However, the duration can vary depending on the severity and other factors. In some cases, symptoms may gradually build up over a few hours or days before the heart attack occurs.
Mini-strokes, or transient ischemic attacks (TIAs), typically last just a few minutes. Symptoms can begin to resolve in about 1 to 5 minutes, and some may take up to 24 hours to resolve.
