Pathogenesis of heart attack
Understand the Problem
The question is asking about the biological and physiological mechanisms that lead to a heart attack, including the factors that contribute to its development and progression.
Answer
Heart attacks occur when plaque buildup in coronary arteries ruptures, forming a clot that blocks blood flow.
A heart attack occurs due to the buildup of plaques in the coronary arteries. These plaques, made of cholesterol and fats, can rupture, leading to blood clots that block blood flow to the heart, causing tissue damage or death.
Answer for screen readers
A heart attack occurs due to the buildup of plaques in the coronary arteries. These plaques, made of cholesterol and fats, can rupture, leading to blood clots that block blood flow to the heart, causing tissue damage or death.
More Information
Plaque formation in arteries is often caused by diet, lifestyle, and genetic factors. When blood flow is blocked, the heart muscle can become damaged or die, leading to a myocardial infarction. Immediate medical attention is crucial.
Tips
Common mistakes include thinking a heart attack is solely due to psychological stress. Also, misidentifying symptoms like chest pain or dismissing early signs can delay treatment.
