High lateral wall myocardial infarction is very dangerous and when a patient has a myocardial infarction it can cause sudden cardiac arrest and sudden death, and the infarction itself can lead to rupture of the papillary muscles, and in some cases cardiac rupture, as well as post myocardial infarction syndrome. In conclusion, myocardial infarction is a very dangerous condition that can jeopardize a person’s life. It is recommended that when an acute myocardial infarction is being considered, a coronary angiogram should be performed. If the patient has severe coronary stenosis, then coronary stent implantation should be given in a timely manner, and for patients who cannot choose coronary stent implantation, then coronary bypass grafting should be performed. If patients cannot choose any of the above procedures, then it is recommended that patients should actively take oral medications to slow down the progression of the disease and improve the prognosis of the patients.
