Left ventricular diastolic weakness in older people in their 70s can be either physiologic, which is normal, or pathologic (most often accompanied by symptoms such as decreased activity endurance, fatigue, and dyspnea), and if pathologic, it is abnormal.
Left ventricular diastolic hypoplasia is not a disease, but an evaluation that describes the diastolic capacity of the heart. Cardiac muscle, like skeletal muscle, decreases in muscle strength and tone with age, and the heart shows a decrease in diastolic function; therefore, in the elderly, LV diastolic dysfunction can occur within a certain range under normal conditions.
If left ventricular diastolic weakness affects hemodynamics, symptoms (e.g., decreased activity tolerance, fatigue, dyspnea, etc.) may occur. This is because in the circulatory system, if the diastolic function of the left ventricle is weakened, the left ventricle will be limited in blood filling, and the increased atrial afterload will result in a gradual enlargement of the atria, obstruction of venous return, and elevation of venous pressure.
If the weakened left ventricular function progresses further, pulmonary stasis may occur, with clinical symptoms such as breath-holding and a marked decrease in activity tolerance. This condition is serious and requires prompt hospitalization.
Therefore, if the patient finds that the left ventricular diastolic function is weakened, he or she must actively go to a regular hospital to prevent further progression of the disease.
