Heart attacks and strokes are medical emergencies that happen suddenly, but they usually start with damage that builds up over time. When they strike, every second counts. Knowing what’s happening in your body and recognizing the signs could help you or someone you love get help fast.
In this article, we’ll walk through what actually happens during a heart attack or stroke, the warning signs to look out for, what to do in an emergency, and how you can lower your risk.
What happens during a heart attack?
Your heart needs a steady flow of oxygen-rich blood to keep beating. This blood is delivered by arteries. Over time, these arteries can get narrowed by plaque, a sticky buildup made of fat and cholesterol. When one of these arteries gets completely blocked, blood can’t reach part of your heart muscle. This is a heart attack.
Without oxygen, that part of the heart begins to die. The longer it goes untreated, the more damage it does.
Common Heart Attack Symptoms:
Chest pain or discomfort, often in the center or left side
Pain that spreads to the shoulders, neck, jaw, or arms
Shortness of breath
Nausea or lightheadedness
Cold sweat or unusual fatigue
For women, symptoms may be different and sometimes more subtle. In addition to chest pain, women are more likely to experience:
Unusual tiredness
Nausea or vomiting
Pain in the back, neck, or jaw
Dizziness or lightheadedness
Shortness of breath without chest pain
Women often wait longer to seek help because their symptoms don’t seem like a “classic” heart attack. But getting help quickly is just as urgent.
What is a stroke?
A stroke occurs when blood flow to the brain is interrupted, either by a blockage (ischemic stroke) or a burst blood vessel (hemorrhagic stroke). Without oxygen-rich blood, brain cells begin to die within minutes.
Stroke can affect movement, speech, and memory. Fast treatment can make a big difference in recovery.
Common Stroke Symptoms: Think FAST
To remember stroke symptoms, use the word FAST:
Face: One side of the face droops or feels numb
Arm: One arm feels weak or numb
Speech: Slurred speech or trouble speaking
Time: Call 911 immediately
Other symptoms may include sudden confusion, trouble seeing, dizziness, or a severe headache with no known cause.
What to Do in an Emergency
If you or someone near you has signs of a heart attack or stroke, call 911 right away. Don’t wait or try to drive yourself to the hospital. Emergency responders can start life-saving treatment on the way.
While waiting for help:
Stay calm and seated
Chew an aspirin (if not allergic and advised by your doctor)
Unlock your door for paramedics
