How would you react to a medical emergency? When it comes to life-threatening conditions like heart attack or stroke, every minute counts. Get to know the signs and symptoms of these health threats. If you think you or someone else might be having a heart attack or stroke, get medical help right away. Call 911. Acting fast could save your life or someone else’s.
That’s the message we put out back in 1991 when I worked at the National Heart, Lung and Blood Institute of the National Institutes of Health (NIH) and we created the National Heart Attack Alert Program. And the message is every bit as important today as it was back then.
Heart disease and stroke are 2 of the leading causes of death among both women and men in the U.S. Nationwide, someone dies from a heart attack about every 90 seconds, and stroke kills someone about every 4 minutes, according to the U.S. Centers for Disease Control and Prevention. Quick medical help could prevent many of these deaths. Fast action can also limit permanent damage to the body.
Heart attack and stroke are caused by interruptions of the normal flow of blood to the heart or brain—2 organs that are essential to life. Without access to oxygen-rich blood and nutrients, heart or brain cells begin to malfunction and die. This cell death can set off a series of harmful effects throughout the body. The changes ultimately lead to the familiar symptoms of a heart or brain emergency.
You might know the most common symptoms of heart attack: sustained, crushing chest pain and difficulty breathing. A heart attack might also cause cold sweats, a racing heart, pain down the left arm, jaw stiffness, or shoulder pain.
Many don’t know that women often have different heart attack symptoms than men. For instance, instead of having chest pain during a heart attack, women may feel extremely exhausted and fatigued or have indigestion and nausea.
“Many women have a vague sense of gloom and doom, a sense of ‘I just don’t feel quite right and don’t know why,’ ” says Dr. Patrice Desvigne-Nickens, an NIH expert in heart health.
The symptoms of stroke include sudden difficulty seeing, speaking, or walking, and feelings of weakness, numbness, dizziness, and confusion. “Some people get a severe headache that’s immediate and strong, different from any kind you’ve ever had,” says Dr. Salina Waddy, an NIH stroke expert.
At the first sign of any of these symptoms, fast action by you, someone you know, or a passerby can make a huge difference. NIH-funded research has helped ensure that more people survive heart attacks and strokes every year. We now have medicines, procedures, and devices that can help limit heart and brain damage following an attack, as long as medical help arrives quickly.
