sydänlihaskudoksen

Sydänlihaskudoksen, also known as myocardial infarction or heart attack, is a medical condition characterized by the death of heart muscle tissue due to a lack of blood supply. This occurs when a coronary artery, which supplies blood to the heart, becomes blocked, typically by a blood clot or plaque buildup. The most common symptom of a heart attack is chest pain or discomfort, which may radiate to the jaw, neck, back, or arms. Other symptoms can include shortness of breath, nausea, lightheadedness, and cold sweat. In women, symptoms may be less typical and can include back pain, jaw pain, shortness of breath, nausea, or vomiting.

The diagnosis of a heart attack is typically made through a combination of medical history, physical examination, and various tests. Electrocardiogram (ECG or EKG) is commonly used to detect changes in heart rhythm and electrical activity. Blood tests, such as troponin, are used to measure the amount of heart muscle damage. Other diagnostic tools may include echocardiogram, stress test, or coronary angiography.

Treatment for a heart attack focuses on restoring blood flow to the affected area of the heart. This can be achieved through medication, such as thrombolytics to dissolve blood clots, or through procedures like angioplasty or coronary artery bypass grafting (CABG). Lifestyle changes, including a heart-healthy diet, regular exercise, and avoiding smoking, are also crucial for preventing future heart attacks and promoting overall heart health.
