No. They are not.
A stroke affects the brain, while a heart attack, as its name suggests, affects the heart. The biggest similarity between them is that they are both life-threatening conditions. Irrespective of whether it’s a stroke or a heart attack, you must visit a nearby hospital for emergency care upon noticing the initial signs.
The section below discusses various causes and symptoms of stroke and heart attack to help you understand their difference.

Heart Attack Vs Stroke
What Causes Stroke?
Based on their causes, strokes can be categorized into two types, ischemic and hemorrhagic, which respectively account for 85% and 15% of all stroke cases.
Ischemic Stroke: An ischemic stroke occurs when the blood vessels inside the brain become narrow or develop blockages. These changes in the blood vessels reduce blood flow; the medical term used to describe this state is “ischemia.”
One may have narrowed or blocked blood vessels due to fatty deposits in the blood vessels. These problems may also occur due to the accumulation of debris and blood clots in the blood vessels. These debris and blood clots travel to the brain’s blood vessels from different parts of the body, via the bloodstream. The most common source of these clots is the heart.
The fatty deposits, debris, or blood clots get lodged in the brain’s blood vessels and trigger an ischemic stroke.
Hemorrhagic Stroke: When a blood vessel leaks or ruptures inside the brain, the patient suffers a hemorrhagic stroke. Bleeding inside the brain, i.e., brain hemorrhage, can occur due to several reasons. Here are the most common ones among them:
- Uncontrolled blood pressure levels in patients with hypertension
- Overconsumption of blood thinners or anticoagulants
- Head trauma from an accident
- Aneurysms, a condition characterized by bulges on the weak spots of the blood vessels
- Amyloid angiopathy, a condition characterized by the accumulation of protein on the walls of the blood vessels
- Protein deposits on blood vessel walls that lead to weakness in the vessel wall. This is known as cerebral amyloid angiopathy.
- Ischemic stroke
- Arteriovenous malformation, a condition marked by the irregular tangling of weak blood vessels
What Causes a Heart Attack?
A heart attack is typically caused by coronary artery disease (CAD). CAD occurs when one or more of the coronary arteries get blocked due to plaque formation (cholesterol buildup).
Blocked arteries are much narrower than the normal ones, which reduces the flow of blood to the heart. When plaques break open, the heart experiences blood clot formation, which leads to the formation of blocked arteries. Heart attacks can occur due to partial as well as complete coronary blockage.
However, there can be other reasons for heart attacks, too. A coronary artery spasm that results in extreme squeezing of a healthy blood vessel can also cause a heart attack. This type of heart attack is more common among smokers.
Viral infections such as Covid 19 can damage heart muscles, resulting in a sudden heart attack. One may also suffer from a heart attack due to spontaneous coronary artery dissection, a condition marked by the tearing of an artery.
Symptoms of Stroke
Below are the symptoms that occur in most stroke patients. A patient who is having a stroke may have one or more of the following:
- The person may find it difficult to speak and understand what others are saying.
- A sense of numbness and weakness in the leg, arm, or face is common. The problem is observed mostly on one side of the body. If not managed at the right time, the patient may become paralyzed.
- Vision problems like double vision, loss of vision, or blurred vision are common in stroke patients. The problem can occur in one or both eyes.
- Consider getting yourself checked by a doctor if you have a severe headache. Dizziness, nausea, and vomiting, along with a headache, are causes of bigger concern.
- Loss of balance is also common in stroke patients.
Symptoms of Heart Attack
- A heart attack can be both symptomatic and asymptomatic. The most common symptoms of the condition are:
- Chest pain and pressure
- Pain and pressure radiating to other body parts such as the shoulder, neck, back, arm, jaw, or upper belly
- Extreme fatigue
- Indigestion marked by heartburn
- Nausea
- Cold sweat
- Breathing difficulties
- Dizziness
- Fainting
- Fainting
