How long a patient with myocardial ischemia can live cannot be generalized. It depends on the degree of the patient’s cardiac primary disease on the one hand, and on the general state of the patient’s whole body on the other. If patients with mild myocardial ischemia are treated actively, it may not affect their life expectancy; if patients with more severe myocardial ischemia or combined with other serious diseases are not treated actively, sudden death may also occur. Therefore, the exact length of time a patient with myocardial ischemia can live varies from person to person. Myocardial ischemia may be induced by non-cardiogenic diseases, such as hyperthyroidism and severe anemia, which will not lead to life-threatening conditions. After active treatment, the patient’s primary disease will gradually disappear and the symptoms of myocardial ischemia will be relieved, which generally will not affect the patient’s long term life expectancy. Myocardial ischemia may also be induced by primary diseases of the heart, such as coronary angina pectoris or myocardial infarction. In mild myocardial ischemia, which does not affect hemodynamics too much and is actively treated with medications, patients usually do not have their life expectancy affected by myocardial ischemia and will live to their natural life expectancy. However, if the patient’s myocardial ischemia is more severe and is not actively treated formally, it may affect the patient’s life as the condition worsens, with sudden death occurring in a few months or years. Of course there are some other factors that may affect the life expectancy of patients, such as age, the older the patient with myocardial ischemia, the overall prognosis is relatively poor. In addition, renal failure, anemia, infection or combination of other serious diseases may also affect the life expectancy of patients. Therefore, the question of how long a patient with myocardial ischemia can live has to be considered comprehensively, and it is impossible to give a very exact number.
