Why Heart Attack Happens? | Causes Of Heart Attack!

Heart attack, also known as myocardial infarction, occurs when the blood flow to a part of the heart muscle is suddenly blocked. Without oxygen and nutrients, the affected heart cells begin to die, leading to permanent damage if not treated in time. Below are the most common causes of heart attack explained clearly: The first cause of heart attack is atherosclerosis. This is the buildup of cholesterol and fatty deposits inside the artery walls. When a plaque ruptures, a blood clot forms and blocks the artery, cutting off blood supply to the heart. The second cause of heart attack is hypertension (high blood pressure). Constant pressure damages the inner lining of arteries, making plaque rupture and blockage more likely. The third cause of heart attack is smoking. Chemicals such as nicotine and carbon monoxide directly damage arteries and increase the tendency of blood to clot. The fourth cause of heart attack is diabetes mellitus. High blood sugar levels stiffen and narrow the arteries, increasing the risk of clots. Diabetics have 2 to 4 times higher risk of heart attack compared to non-diabetics. The fifth cause of heart attack is obesity and sedentary lifestyle. Excess body fat leads to insulin resistance, high cholesterol, and high blood pressure — all three together greatly increase the risk. The sixth cause of heart attack is family history and genetics. If parents or siblings had heart disease at a young age, the risk almost doubles. The seventh cause of heart attack is chronic stress and anxiety. Constant release of stress hormones like adrenaline and cortisol raises blood pressure and clotting, putting the heart at risk. Conclusion: A heart attack is not just a sudden event — it’s the result of years of damage caused by multiple risk factors. Prevention is possible: control your cholesterol, blood pressure, and sugar, quit smoking, manage stress, and stay physically active to keep your heart strong and healthy. #heartattack #mayocardialinfarction #heartdisease #heartattackcauses #atherosclerosis
