A heart attack, or myocardial infarction, occurs when blood flow to a part of the heart is blocked, depriving it of oxygen and causing damage to heart muscle. Time is the most critical factor in saving your life and preventing long-term damage. If you suspect you or someone near you is having a heart attack, call emergency services immediately—do not attempt to drive yourself to the hospital. While waiting for help, chew (do not swallow whole) a regular aspirin, as it can help thin the blood and improve circulation to the heart.
Classic symptoms include chest pain or pressure, pain radiating to the arm, jaw, neck, or back, shortness of breath, cold sweats, nausea, and lightheadedness. However, symptoms can vary—particularly in women, older adults, and people with diabetes—who may experience subtle signs such as fatigue, indigestion, or dizziness. Knowing these variations could save a life. If you have nitroglycerin prescribed by your physician, take it as directed while awaiting emergency responders.
After a heart attack, rapid medical intervention—such as opening blocked arteries with angioplasty or stenting—can dramatically improve outcomes. This is why my Concierge Medicine patients benefit from 24/7 access to me; immediate medical guidance can make a crucial difference in those first minutes. Prevention, however, remains the best approach. Managing blood pressure, cholesterol, and blood sugar levels, along with a heart-healthy diet and regular exercise, dramatically lowers your risk of ever needing to make this life-or-death call.
