What causes a stemi heart attack?

A STEMI heart attack, also known as an ST-elevation myocardial infarction, occurs when there is a complete blockage in one of the coronary arteries. These arteries supply the heart muscle with oxygen-rich blood. When the blood flow is severely reduced or stopped, the part of the heart muscle that is dependent on that artery for oxygen starts to die, leading to a heart attack. The blockage is typically caused by a blood clot that forms on top of a plaque (atherosclerotic lesion) that has developed in the artery over time. The plaque is made up of fat, cholesterol, calcium, and other substances that can narrow the artery and make it more susceptible to clotting. Risk factors for a STEMI heart attack include: 1. Age: The risk increases with age, especially after 40 years old. 2. Gender: Men are more at risk than premenopausal women, but after menopause, the risk for women increases. 3. Smoking: It damages the inner lining of the arteries and makes them more prone to plaque formation. 4. High blood pressure: It puts extra strain on the heart and can lead to plaque buildup. 5. High cholesterol: Excess cholesterol can build up in the arteries, forming plaques. 6. Diabetes: It accelerates the process of plaque formation. 7. Obesity: It increases the strain on the heart and can contribute to plaque formation. 8. Physical inactivity: It can contribute to the development of heart disease. 9. Family history: A family history of heart disease can increase the risk. Immediate medical attention is crucial for someone experiencing a STEMI heart attack, as the sooner the blockage is treated, the less damage to the heart muscle.

ST-elevation myocardial infarction, or a STEMI heart attack, happens as a result of a complete blockage in a coronary artery. A STEMI attack carries a great risk of death and disability. When an artery is partially blocked and severely reducing blood flow, a non-STEMI heart attack may occur.
