Blood score 33 is already too low. It may be dangerous, so you need to go for treatment.
A normal person’s ejection fraction is between 55% and 70%. Usually in ejection fraction 40%~50% can be symptomless, but once in 30%~40%, the blood pumped out by the heart generally can no longer meet the daily needs of the body, belonging to the heart failure with lowered ejection fraction, and even if there are no symptoms, the relative risk is higher.
Lower limb edema, nocturnal paroxysmal dyspnea, palpitations, dizziness and other symptoms may occur afterwards, which may affect daily life and increase the probability of sudden death, so you need to go to the hospital as soon as possible to determine the cause of the disease.
Therefore, it is necessary to go to the hospital as soon as possible to determine the cause of the disease, such as ischemic myocardial damage, hypertension and other diseases, and targeted treatment to improve the ejection fraction and reduce the risk.
It is recommended to seek medical attention as soon as possible if you have any relevant symptoms, and you need to consult your doctor for the specific treatment to be used.
