Hart attack

 Hart attack 

A heart attack, also known as a myocardial infarction, occurs when there is a blockage in the blood flow to the heart, leading to damage or death of the heart muscle. This blockage is often caused by a buildup of plaque in the arteries that supply blood to the heart. Symptoms of a heart attack can include chest pain, shortness of breath, nausea, vomiting, and lightheadedness.

It is essential to seek immediate medical attention if you suspect you or someone you know is having a heart attack. Treatment for a heart attack typically involves medications to dissolve or prevent blood clots, relieve chest pain, and reduce the workload on the heart. In severe cases, procedures like angioplasty or bypass surgery may be necessary to restore blood flow to the heart
