In Understanding Your Symptoms
Heart Attack Warning Signs You Should Never Ignore

Key takeaways
- Classic symptoms: chest pressure, shortness of breath, sweating, nausea, arm or jaw pain.
- Women often present atypically: fatigue, back or upper abdominal pain, unusual shortness of breath.
- Call 911 immediately — do not drive yourself to the hospital.
- Chew a regular-strength aspirin (325 mg) unless you are allergic or your doctor has told you not to.
Classic warning signs
Chest pressure or tightness — often described as 'an elephant sitting on my chest' — lasting more than a few minutes or coming and going. Pain may radiate to the left arm, jaw, neck, or back.
Shortness of breath, cold sweats, nausea, lightheadedness, or a sense of impending doom are common accompaniments.
Atypical symptoms — especially in women
Women, older adults, and people with diabetes may not have crushing chest pain. Instead they may notice unusual fatigue over days, jaw or back pain, indigestion-like discomfort, or shortness of breath with normal activity.
Any new, unexplained symptom that comes with exertion and improves with rest deserves attention — even without classic chest pain.
What to do in the first minutes
Call 911. Emergency medical services can begin treatment on the way to the hospital and route you to a cardiac catheterization lab faster than any private vehicle.
If you are not allergic and not otherwise instructed, chew (do not swallow whole) one 325 mg aspirin. Unlock your door for paramedics and sit down.
When to see a cardiologist
Any suspected heart attack is a 911 emergency, not a doctor's visit. After hospitalization or if you have known coronary disease and want to reduce future risk, a cardiologist can review your medications, imaging, and lifestyle strategy to prevent a second event.
