Most left ventricular diastolic insufficiency is not recoverable and is an end-stage change of organic heart disease. Left ventricular diastolic hypoplasia can be clarified mainly from the ultrasound of the heart and can be present in patients with cardiac insufficiency. Common causes include left ventricular hypertrophy, mitral valve closure insufficiency, myocardial densification insufficiency, myocardial ischemia, and myocarditis. Some older patients with myocardial strain can also present, often with fibrosis of the heart, which can manifest as dyspnea, wheezing, chest tightness, and edema of both lower extremities. If the symptoms worsen after postural activities, active treatment can be considered according to the specific cause, and the development of myocardium can be effectively inhibited after active oral medication. Usually, we must pay attention to control the underlying disease, pay attention to increase rest and reduce overexertion.
