What is the cause of myocardial ischemia? What should I do if my heart is ischemic?

What is myocardial ischemia? Myocardial ischemia is a manifestation of coronary heart disease. Coronary heart disease is a blood vessel that nourishes the heart, that is, coronary atherosclerosis leads to coronary artery stenosis, which leads to decreased coronary blood supply, and decreased blood flow leads to myocardial ischemia, which leads to angina pectoris and heart pain, especially during exercise.

Generally, there will be ST segment changes in ECG. Some doctors will say that the ST segment change of ECG is myocardial ischemia. In fact, there is no way to diagnose myocardial ischemia by ECG alone. The best way to diagnose myocardial ischemia is to do coronary CT or coronary angiography. Only these two tests can determine whether there is myocardial ischemia.

Causes of myocardial ischemia There are many clinical causes of myocardial ischemia. Myocardial ischemia is mostly caused by stenosis or occlusion of the lumen caused by coronary atherosclerosis, which leads to myocardial ischemia and hypoxia and coronary atherosclerotic heart disease.

Other causes of myocardial ischemia include severe anemia, hypotension, coronary artery spasm, coronary artery disease caused by syphilitic Takayasu's arteritis, rheumatic coronary arteritis, hypertrophic obstructive cardiomyopathy, severe stenosis or insufficiency of aortic valve, etc. These diseases can also lead to insufficient coronary blood supply, which leads to myocardial ischemia.

Symptoms of myocardial ischemia The typical symptom of myocardial ischemia is angina pectoris. Chest pain may occur after fatigue and heavy physical labor. Of course, there may also be symptoms such as high heart pressure, chest tightness and radiation pain in the left upper limb.

When myocardial ischemia occurs, patients will feel chest tightness, and chest pain will occur in severe cases. The degree of chest pain will be different due to different causes.

Treatment of myocardial ischemia There are many reasons for myocardial ischemia. For example, myocardial ischemia caused by coronary heart disease, the treatment of coronary heart disease: first give aspirin and other anti-platelet aggregation drugs; Second, give lipid-regulating drugs, such as rosuvastatin calcium tablets to control blood lipids. If myocardial ischemia is caused by myocardial bridge, what needs to be done is to control the ventricular rate, and metoprolol tablets can be selected.

If it is myocardial ischemia caused by cardiac neurosis, it needs double heart treatment, mainly psychological intervention, encouraging relaxation and adjusting mentality; You can also use some drugs that nourish the heart muscle, such as trimetazidine hydrochloride tablets. If it is due to other reasons, such as myocardial ischemia caused by poor rest or recent excessive fatigue, what needs to be adjusted is not to be too tired, to sleep too little, to pay attention to rest and diet, to pay attention to a low-salt and low-fat diet at ordinary times, and to exercise properly. Plus the routine.
