High blood pressure and myocardial infarction are closely related. The danger of high blood pressure lies not in the condition itself, but in its complications, and myocardial infarction is one of the complications of high blood pressure. High blood pressure increases the risk of developing myocardial infarction, so effectively controlling high blood pressure can reduce the mortality rate of myocardial infarction.
High blood pressure can damage various organs in the body, especially the heart and blood vessels. Increasing evidence suggests that although high blood pressure itself is not fatal, long-term uncontrolled high blood pressure can easily lead to fatal myocardial infarction.
High blood pressure mainly increases the risk of myocardial infarction through the following aspects:
1. High blood pressure promotes coronary atherosclerosis, narrowing the lumen of the blood vessels and reducing the blood supply to the myocardium.
2. Long-term high blood pressure leads to left ventricular hypertrophy, causing structural changes in the capillaries in the heart muscle, making it unable to provide sufficient blood supply to the myocardium.
3. High blood pressure easily triggers coronary artery spasm, causing closure of the coronary artery and interrupting the blood supply to the myocardium.
4. Sudden increase in blood pressure can cause rupture and detachment of existing atherosclerotic plaques, forming blood clots that block the coronary artery. Studies have shown that effectively controlling high blood pressure can reduce the mortality rate of myocardial infarction by 27%.
Therefore, controlling high blood pressure is of great importance in preventing myocardial infarction.
