Heart Attack
The thought of having a heart attack can be very unsettling. You may think heart attack symptoms come on suddenly, but they can occur gradually as well. Call 911 or get emergency care if you or a loved one has symptoms of a heart attack.
Learn the signs and symptoms of heart attack
Every 43 seconds, a heart attack occurs in the US. If you have a blockage that interrupts blood flow to your heart, you could be at risk. Permanent heart damage can result from this very serious cardiovascular condition.

- Cold sweats
- Nausea
- Dizziness
- Fullness, burning, squeezing, or pressure in your chest
- Chest discomfort that spreads to your arms, back, shoulders, jaw, or abdomen
Heart attack symptoms may differ between men and women. In women, symptoms may include nausea or fatigue that occurs with chest pain. If you don’t feel quite right, get immediate care. Early treatment protects your heart from damage and can save your life.

Preventive treatment for heart attack causes
Your heart needs oxygen and nutrients to keep it healthy. If your heart lacks these basic elements, your heart muscle can start to die and put you at risk for a heart attack.
Heart attack can occur from several conditions, including:
- Spontaneous coronary artery dissection, a sudden tear in your coronary artery where blood becomes trapped and blocks blood flow to your heart
- Coronary artery spasm, which narrows your artery, slowing or blocking blood flow
- Plaque buildup and blood clots in the coronary arteries, the most common causes of a heart attack
Your doctor may order a chest X-ray, blood tests, electrocardiogram, coronary angiography, and echocardiogram to help identify heart attack causes and diagnose your heart condition. Dignity Health heart doctors will create a personalized treatment plan and provide care with humankindness.
