1, acute myocardial infarction must sit If it is really an acute myocardial infarction, because the patient has heart failure, sitting can reduce the return blood flow and reduce the load on the heart, which can relieve the symptoms. But if there is no heart failure, prone or semi-prone position is also possible. 2, after putting the stent can not leave the drug, the stent must not be put Need to clarify the causal relationship, coronary heart disease acute myocardial infarction, even if not put the stent, but also to regulate the medication. And not because the stent is put to take drugs. If the stenosis is severe, stent implantation can reduce or save the dying myocardium, which can improve the salvage rate and reduce death. After stenting, in order to improve the quality of life and prognosis, standardized medication is needed. 3, when the heart attack to immediately use nitroglycerin If it is angina, blood pressure did not fall, you can contain nitroglycerin or quick-acting heart pills; but if the blood pressure falls (mostly seen in the anterior wall myocardial infarction, right ventricular infarction), at this time can not contain nitroglycerin, because it will cause a more powerful drop in blood pressure, harmful to health. In addition, when it is not relieved after taking more than half an hour, it is recommended to go to the hospital immediately, because either it is myocardial infarction, aortic entrapment, etc., or not cardiogenic chest pain. 4, acute myocardial infarction, needle bleeding, or massage rescue Acute myocardial infarction as an acute and critical condition, the correct approach is to call 120 at the first time, and must be as soon as possible to the nearest regular hospital to receive professional treatment, including drug therapy, thrombolytic therapy, interventional therapy. Any other methods such as bloodletting, massage, etc. are ineffective and can prolong the best time for treatment and delay the disease. 5, chew high dose aspirin when chest pain There are many causes of chest pain, divided into cardiogenic and non-cardiogenic, cardiogenic if it is an acute myocardial infarction, you can chew aspirin, but if the usual standard daily aspirin, it is not necessary to take additional medication at this time. Certain cardiogenic chest pains such as aortic coarctation are contraindicated to take aspirin. For non-cardiogenic chest pain, taking aspirin is ineffective or harmful.
