There is still much uncertainty about the pathophysiology of diastolic heart failure, | There is still much uncertainty about the pathophysiology of diastolic heart failure, effective treatment has not surfaced yet while it has a similar high mortality and morbidity rate when compared to systolic heart failure. One of the characteristics of diastolic heart failure is an increased LV diastolic stiffness. There are several important measurements echocardiographic measurement to estimate cardiac diastolic performance. | ||
