Heart Attack Warning Signs: Recognize the Symptoms and Act Fast

Myocardial infarction (heart attack) symptoms vary widely. Classic and atypical presentations both require immediate emergency response.

Chest Discomfort — The Hallmark

• Pressure, squeezing, fullness, burning, tightness in center or left chest
• Lasts > few minutes; may wax and wane
• Radiates to jaw, neck, shoulders, arms (especially left), back, epigastrium

Shortness of Breath

• At rest or minimal exertion
• Orthopnea (need to sit up)
• May precede or occur without chest pain

Associated Symptoms

• Diaphoresis (cold sweat) — very specific
• Nausea, vomiting, indigestion-like sensation
• Lightheadedness, syncope, presyncope
• Unexplained fatigue (especially women, elderly, diabetics)
• Palpitations, sense of doom

Special Populations

• Women: More often present with atypical triad — fatigue, nausea, jaw/back pain — without classic chest pressure.
• Diabetics: Autonomic neuropathy → silent ischemia (no pain).
• Elderly: Confusion, syncope, dyspnea may dominate.

⏱ TIME IS MUSCLE

Call 911 immediately if heart attack suspected. Do not drive yourself. Chew 325 mg aspirin (if not allergic) while waiting. EMS provides ECG, oxygen, nitroglycerin, and pre-hospital activation of cath lab.

Every minute of delay increases infarct size and mortality. Trust your instincts—better a false alarm than a missed MI.
