sydäninfarktien

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, a fatty substance, within the coronary arteries, which supply blood to the heart. When this plaque ruptures, a blood clot can form and obstruct blood flow.

The reduced or absent blood flow deprives the heart muscle of oxygen, leading to damage or death of heart tissue. Symptoms of a heart attack can vary but often include chest pain or discomfort, which may feel like pressure, squeezing, fullness, or pain. This pain can radiate to the arm (usually the left), jaw, neck, or back. Other symptoms can include shortness of breath, cold sweats, nausea, vomiting, and lightheadedness.

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

Prompt medical attention is crucial for a heart attack. Treatment aims to restore blood flow to the heart muscle as quickly as possible to minimize damage. This may involve medications to dissolve blood clots, angioplasty and stenting to open blocked arteries, or bypass surgery. Lifestyle changes, such as adopting a healthy diet, exercising regularly, quitting smoking, and managing stress, are important for preventing future heart attacks and improving overall cardiovascular health.
