Left ventricular hypodiastolic function is caused by myocardial ischemia and myocardial fibrosis. Patients with left ventricular hypodiastolic function will experience weakness, panic and chest tightness, dyspnea and other symptoms. 1. Weakness: Due to the hypodiastolic function of the left ventricle of the heart, patients will have symptoms of heart failure, that is to say, they will have symptoms of weakness, fatigue and poor mental state. 2. Panic and chest tightness: due to hypodiastolic function of the left ventricle of the heart, myocardial ischemia and hypoxia, patients will experience panic, chest tightness, shortness of breath and other symptoms. 3. Dyspnea: due to the left ventricular diastolic dysfunction of the heart, the heart rate becomes faster and the burden on the heart increases, which will lead to dyspnea as a result of cardiac insufficiency, and in severe cases, it may lead to shock due to difficulty in breathing. Patients suffering from left ventricular hypodiastolic symptoms should go to the hospital in time for examination and follow the doctor’s instructions for appropriate treatment.
