When a medical emergency takes place, every second counts. Two of the most severe issues that people shall face are strokes and heart attacks. While they both involve the systems that pump and carry blood through our bodies, they shall take place in two very different places: the brain and the heart. Knowing the difference between a stroke vs. heart attack is just about learning medical facts and it is about it is about knowing exactly what to do when someone shall need help.
What is a Heart Attack? (Myocardial Infarction)
A heart attack, known in the medical world as a myocardial infarction, happens when blood flow to a part of the heart muscle which shall be blocked. Think of the heart as a pump. If the pipes shall lead to that pump are clogged, the pump stops might work correctly. Without oxygen-rich blood, the heart muscle begins to suffer damage.
Most of the heart attacks are a result of cardiovascular disease. This is about a condition where arteries shall be narrow over time due to a buildup of plaque (a mix of fat and cholesterol). If a piece of that known plaque shall break off, a blood clot forms. This is one of the primary causes of heart attack as it shall create a "roadblock" in the artery.
What is a Stroke?
While a heart attack is a "circulation" issue that occurs in the heart, a stroke is often called a "brain attack." This occurs when the blood supply to part of the brain is interrupted or reduced. It also prevents brain tissue from getting the oxygen and nutrients it shall need.
There are two main causes of stroke which can be medical professionals look for:
- Ischemic Stroke: This is the most common type, as per most cases. It can occur when a blood vessel carrying blood to the brain is blocked by a clot.
- Hemorrhagic Stroke: This is less common but very serious. It happens when a blood vessel in the brain weakens and bursts or leaks.
In both cases, brain cells begin to die within minutes. This is why immediate medical attention is the only way to reduce the risk of long-term disability.
Stroke vs. Heart Attack Symptoms: How to Tell
The biggest difference between these two emergencies is how they show up in the body. Because the heart and brain control different functions, the warning signs are unique.
Heart Attack Symptoms
A heart attack usually involves the chest and upper body. Common signs include:
- Chest pain or pressure: It might feel like a heavy weight is sitting on your chest, or like a squeezing sensation that doesn't go away.
- Pain in the "upper" body: This pain often spreads. You might feel it in your neck, jaw, back, or even in your stomach. Many people feel a dull ache specifically down the left arm.
- Shortness of breath: You might feel like you can’t catch your breath, even if you are sitting still.
- Other signs: Cold sweats, feeling sick to your stomach (nausea), or feeling lightheaded.
Stroke Symptoms
A stroke primarily affects your motor skills, your ability to speak, and your senses. Doctors often use the acronym F.A.S.T. to help people remember stroke symptoms:
- F (Face): Does one side of the face droop or feel numb? Ask the person to smile to see if it is uneven.
- A (Arms): Is one arm weak? Ask the person to raise both arms. If one drifts downward, that is a red flag.
- S (Speech): Is their speech slurred? Can they repeat a simple sentence correctly?
- T (Time): If you see any of these signs, even if they go away, it is time to call emergency services immediately.
Understanding the Risks
Even though they happen in different organs, both conditions often share the same roots in cardiovascular disease. This means the health of your blood vessels plays a huge role in your overall risk.
Common factors that increase the risk for both a heart attack and a stroke include high blood pressure, high cholesterol, and smoking. When blood pressure is too high, it puts constant stress on the walls of your arteries, making them more likely to clog or burst.
According to the Centers for Disease Control and Prevention (CDC), managing your "ABCS" (Aspirin, Blood pressure, Cholesterol, and Smoking cessation) is a proven way to lower these risks.
What Should You Do in an Emergency?
Whether you suspect a heart attack or a stroke, the advice from health experts is the same. Do not try to drive yourself or a loved one to the hospital. Paramedics can begin life-saving treatment the moment they arrive at your door. For an ischemic stroke, doctors have a very limited window of time to give "clot-busting" medications that can stop the stroke and reverse the damage. Similarly, for a heart attack, the sooner the blockage is cleared in a hospital, the less permanent damage occurs to the heart muscle.
