The need for treatment of left ventricular hypodiastolic function depends on the specific situation, as follows: 1. No treatment is needed: normal people have physiological hypo-diastolic function due to aging, this condition does not require treatment and generally does not lead to adverse consequences; 2. Treatment is needed: those suffering from related diseases that lead to hypo-diastolic left ventricular function need to be given active treatment, such as hypertension and Heart disease caused by the need to actively control blood pressure, as well as giving drugs to inhibit myocardial remodeling, to control the patient’s condition. In patients with coronary artery disease, active improvement of myocardial ischemia, stabilization of atherosclerotic plaques, and prevention of plaque formation of thrombus are the only long-term standardized treatment to effectively control the patient’s condition.
