Ejection fraction 33-36 belongs to heart failure, can be treated or not, depends on whether the myocardium has occurred a wide range of irreversible damage, if irreversible damage occurs, usually can not be cured, if the myocardial damage is small or no damage occurs, usually can be cured. 1. Can not be cured: ejection fraction is the heart beating, the left ventricular ejection volume of blood as a percentage of the diastolic volume of the left ventricle, which can reflect the strength of the heart beat, and the strength of myocardial contraction is positively correlated with the myocardial contraction, if the myocardium occurs a wide range of irreversible injuries, the beating myocardium reduces, which may lead to the ejection fraction of 33-36, and the myocardium is not regenerative, therefore, this case can not be cured, can only be maintained by medication, but It is possible to bring the ejection fraction back to the normal range. 2. Can cure: ejection fraction 33-36, may be due to coronary atherosclerosis caused by myocardial ischemia, resulting in myocardial hypoxia, energy deficiency, myocardial contraction weakness, or myocarditis resulting in myocardial inflammatory edema, contraction capacity is limited, and myocardial damage is small or no damage, at this time, can be improved by improving the myocardial blood supply, elimination of myocardial edema, so that the weakness of contraction of the cardiomyocytes to return to normal, improve the contraction force of the heart, and thus treatment is good. Strength, and thus the treatment is good. Ejection fraction of 33-36 is a lower value, it is recommended to consult a doctor in time, under the guidance of the doctor, for standardized treatment.
