Sydäninfarktiin

Sydäninfarkti, commonly known as a heart attack, is a serious medical condition that occurs when blood flow to a part of the heart muscle is severely reduced or completely blocked. This blockage is typically caused by a buildup of plaque in the coronary arteries, which can rupture and form a blood clot. The lack of oxygenated blood damages or destroys the affected heart muscle.

The most common symptom of a heart attack is chest pain or discomfort, often described as pressure, squeezing, or fullness in the center of the chest. This pain can radiate to the arm (usually the left), jaw, neck, back, or stomach. Other symptoms may 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 back or jaw.

Risk factors for heart attack include high blood pressure, high cholesterol, diabetes, smoking, obesity, lack of physical activity, and a family history of heart disease.

Immediate medical attention is crucial for a suspected heart attack. Treatment aims to restore blood flow to the heart muscle as quickly as possible. This can involve medications to dissolve clots or procedures like angioplasty and stenting to open blocked arteries. Lifestyle changes, such as a healthy diet, regular exercise, and smoking cessation, are important for preventing future heart attacks and managing recovery.
