hjartaáfalli

Hjartaáfall, also known as a myocardial infarction, is a serious medical condition that occurs when blood flow to a part of the heart muscle is severely reduced or blocked. This typically happens due to a buildup of plaque in the coronary arteries, which can rupture and form a blood clot. The blockage prevents oxygen-rich blood from reaching the heart muscle, causing it to become damaged or die.

The most common symptom of a hjartaáfall is chest pain or discomfort, often described as pressure, squeezing, or fullness. This pain can radiate to the arm, jaw, neck, or back. Other symptoms may include shortness of breath, cold sweats, nausea, vomiting, and lightheadedness. Symptoms can vary between individuals, and some may experience them without significant chest pain.

Risk factors for hjartaáfall include high blood pressure, high cholesterol, diabetes, obesity, smoking, a sedentary lifestyle, and a family history of heart disease. Early recognition of symptoms and prompt medical attention are crucial for survival and minimizing damage to the heart muscle. Treatment often involves medications to dissolve blood clots, improve blood flow, and reduce the heart's workload. Lifestyle changes, such as a healthy diet, regular exercise, and smoking cessation, are vital for recovery and preventing future events.
