sydämeninfarktiin

Sydämeninfarkti, commonly known as a heart attack, occurs when blood flow to a part of the heart muscle is blocked, usually by a blood clot. This blockage deprives the heart muscle of oxygen, causing it to die or become damaged. The most common underlying cause is coronary artery disease, where plaque builds up in the arteries that supply blood to the heart.

Symptoms of a heart attack can vary but often include chest pain or discomfort, which may feel like pressure, squeezing, fullness, or pain in the center of the chest. This pain can radiate to the arms, jaw, neck, or back. Other common symptoms include shortness of breath, cold sweats, nausea, vomiting, and lightheadedness. Women may experience less typical symptoms, such as fatigue, indigestion, or pain in the upper abdomen.

Risk factors for heart attack include high blood pressure, high cholesterol, diabetes, obesity, smoking, a sedentary lifestyle, and a family history of heart disease. Age is also a factor, with risk increasing as people get older.

Immediate medical attention is crucial for a heart attack. Prompt treatment can limit damage to the heart muscle and improve the chances of survival. Treatment typically involves medications to dissolve the clot or open the blocked artery, such as aspirin, clot-busting drugs, or angioplasty with stenting. Lifestyle changes, including a healthy diet, regular exercise, and smoking cessation, are essential for recovery and preventing future events.
