According to the French Federation of Cardiology, around 80,000 people in France suffer a heart attack each year. Alarmingly, 10% die within the first hour, and 15% within a year. Swift action within two hours maximizes treatment success and survival chances. Recognizing warning signs can be lifesaving.
A heart attack, or myocardial infarction, strikes when a blood clot blocks a coronary artery—the vessel supplying oxygen-rich blood to the heart muscle, which contracts rhythmically to pump blood.
This obstruction starves the muscle of oxygen, causing tissue death (necrosis) and impairing heart function, potentially leading to cardiac arrest.
Key risk factors include diets high in saturated fats, smoking, elevated cholesterol, hypertension, diabetes, obesity, sedentary habits, stress, and depression. Men face higher risk, but women are increasingly affected. Family history, age over 55, and arterial thickening from cholesterol plaques also elevate danger.
Most heart attacks present classic symptoms, though 25% are "silent." These signs demand immediate action due to high mortality risk.
The most telling is severe chest pain or tightness, often with anxiety, lasting at least 20 minutes. It may onset suddenly or in waves, radiating to the throat, jaw, shoulders, arms (especially left), or wrists.
Accompanying symptoms can include profound fatigue, shortness of breath, palpitations, dizziness, pallor, cold sweats, nausea, or vomiting. Pay extra attention if they occur at rest or without exertion.
If intense chest pain persists over 20 minutes—even at rest—with other symptoms, time is critical as damage progresses rapidly. The French Federation of Cardiology states: "The first two hours are decisive for implementing treatments that condition life. The gain in survival is all the greater the earlier, more complete, and longer-lasting the restoration of myocardial blood flow: reduction in mortality by 50% for treatment during the first hour and by 30% the second."
Stop all activity and call SAMU emergency services at 15 immediately for assessment. Optimal care involves rapid artery recanalization in an interventional cardiology unit.
