Edema can occur after myocardial infarction. Myocardial infarction is an ischemic necrosis of the myocardium caused by blockage of the coronary arteries, which triggers insufficient blood supply. Myocardial ischemia causes a decline in heart function, which leads to heart failure. At this time, the heart has abnormal diastolic function and is unable to eject sufficient blood into the pulmonary arteries, the right ventricular stasis increases, the venous return blood volume decreases, resulting in stasis in the body circulation or stasis in the pulmonary circulation, and the increase in venous pressure causes the blood to penetrate into the tissue interstitial space, which in turn causes edema. Patients may also have enlarged liver, pleural fluid (fluid that stays in the thoracic cavity), ascites, pericardial effusion, jugular vein raging, etc. Diuretics such as torasemide tablets and furosemide tablets can be applied to alleviate the phenomenon of edema under the guidance of the doctor, and treatments targeting myocardial ischemia are also available so as to improve the function of the heart. If you feel unwell, you should seek medical advice and treatment in time.
