Acute myocardial infarction is also commonly known as a heart attack. It occurs when the blood flow to the heart muscle is interrupted, resulting in damage or death of the heart muscle cells. Other synonyms for this condition include coronary thrombosis, coronary occlusion, and acute coronary syndrome. The symptoms of a heart attack may include chest pain, shortness of breath, sweating, nausea, and fatigue. Immediate medical attention is essential to prevent further damage or complications. Treatment may involve medication, lifestyle changes, or surgery, depending on the severity of the condition. Leading a healthy lifestyle and managing risk factors such as high blood pressure, high cholesterol, and smoking can help prevent heart attacks.
