Heart aortic blockage belongs to a type of atherosclerotic occlusion, which may be life-threatening if not treated in time. Occurrence of cardiac aortic occlusion may suddenly cause insufficient blood supply to the heart muscle, myocardial hypoxia, etc. Without timely treatment, the patient may suddenly feel discomfort in the heart, with symptoms such as chest tightness, chest pain, burning sensation, etc., and in severe cases, it may cause acute angina or myocardial infarction, so the cardiac aortic occlusion may be life-threatening. When heart aortic occlusion causes acute myocardial infarction, it should be treated as soon as possible with drugs such as nitroglycerin and metoprolol, which have the effects of vasodilatation and antiarrhythmia, thus reducing myocardial ischemia, insufficient blood supply to the heart and other symptoms. If cardiac aortic occlusion occurs and the use of the above drugs is required, it should be carried out under the guidance of a physician to avoid unauthorized use causing adverse reactions. During an acute attack, it is also necessary to pay attention to rest to reduce myocardial oxygen consumption. In the event of cardiac aortic occlusion, please consult the hospital in time to avoid delaying the condition.
