Simple left ventricular hypodiastolic dysfunction has little to do with food and only requires a balanced and complete nutritional diet. In combination with hypertension, a low-sodium and high-potassium diet is needed, and diabetic patients need to choose foods with a low glycemic index and low glycemic load. There are two types of left ventricular hypodiastolic function: physiologic and pathologic. Physiologic decompensation is mainly related to age, myocardial aging, and other factors, and is usually triggered by colds, pneumonia, and excessive exercise. Pathologic myocardial diastolic hypoplasia is mainly related to myocardial damage caused by hypertension and diabetes mellitus. If the symptoms are obvious, diuretic drugs such as furosemide and spironolactone can be used to reduce the vascular volume and relieve the symptoms, and calcium antagonists such as nifedipine and beta-blockers such as propranolol can also be used appropriately. Patients with left ventricular hypodiastolic function in combination with hypertension need a low-salt diet, with a daily sodium intake of less than 5 grams. Patients with diabetes need to choose foods with a low glycemic index and low glycemic load, avoid processed foods with too much added sugar, and moderately increase the amount of coarse grains, mixed beans and other foods with a relatively low glycemic index. Left ventricular hypodiastolic function, once diagnosed, please improve the examination, cooperate with the doctor treatment. Please follow the doctor’s instructions for the above medications.
