Symptoms of acute myocardial ischemia?

summary

Myocardial ischemia refers to a pathological state in which the blood perfusion of the heart is reduced, resulting in the decrease of oxygen supply to the heart and abnormal energy metabolism of the heart, which can not support the normal work of the heart. The energy needed for heart activity is almost completely provided by aerobic metabolism, so even when it is quiet, the blood oxygen uptake rate of myocardium is also very high (about 70%). Under normal circumstances, the body can make the blood supply and demand relatively constant through self-regulation, so as to ensure the normal work of the heart.

Symptoms of acute myocardial ischemia?

1. When you are tired or nervous, you will have stuffy pain or constrictive pain in the sternal or precordial area, and radiate to the left shoulder and upper arm, lasting for 3-5 minutes. After rest, you can relieve yourself, accompanied by sweating. 2. Chest tightness, palpitation and shortness of breath appear during physical activity, and they can relieve themselves during rest.

3. Sore throat, burning, constriction and toothache related to exercise. 4. Chest pain and tightness after full meal, cold and drinking. 5. When the pillow is low at night, I feel chest tightness and suffocation, so I need a high pillow position to feel comfortable; If you have chest pain, palpitation or dyspnea when you are sleeping or lying flat during the day, you need to sit up or stand up immediately to relieve them.

6. Palpitation, chest tightness, shortness of breath or chest pain during sex or forced defecation. 7. Sudden bradycardia, hypotension or syncope. 8. Unexplained tiredness and lack of energy. 9. Patients without typical symptoms only feel stomach discomfort, nausea, or toothache, cervical pain, etc.

matters needing attention

Because myocardial ischemia has the risk of myocardial infarction and sudden death, it should be treated as soon as possible. We should actively prevent the occurrence of atherosclerosis. If it has occurred, we should actively treat it, prevent the development of the disease and strive to reverse it. Patients with complications should be treated in time to prevent deterioration and prolong life.
