心脏舒张功能不全指心脏舒张期有生理功能异常,可伴或不伴充血性心力衰竭的症状及射血分数的异常。流行病学表明舒张功能不全十分常见,有报道1/3的心力衰竭患者左室收缩功能正常。目前舒张性心功能不全的诊断来自于临床表现和实验室检查,存在一定的局限性。现介绍心脏舒张功能不全的超声心动图评价,使临床医师更加重视舒张性心功能不全的诊治。 Cardiac diastolic dysfunction refers to cardiac diastolic physiological abnormalities, with or without congestive heart failure and ejection fraction abnormalities. Epidemiology shows that diastolic dysfunction is very common. It has been reported that one third of patients with heart failure have normal left ventricular systolic function. The current diagnosis of diastolic heart failure comes from clinical manifestations and laboratory tests, there are some limitations. Now introduced echocardiographic assessment of diastolic dysfunction, clinicians pay more attention to the diagnosis and treatment of diastolic heart failure.
