Diastolic dysfunction is a key factor in the pathogenesis of heart failure. Around 50% of cases of heart failure, the hemodynamic correlate of which is increased left ventricular filling pressure, are caused by diastolic dysfunction in the setting of apparently normal systolic function. Due to its high prevalence, diastolic dysfunction is often recognized as an incidental finding. Many patients have Doppler echocardiographic evidence of impaired diastolic function but do not have any symptoms of heart failure at rest. In many of these patients, symptoms of diastolic dysfunction occur only during exercise, as left ventricular filling pressure is normal at rest, but increases with exercise. This implies that filling pressures should also be measured during exercise. The diastolic stress test refers to the evaluation of diastolic function, either invasively or noninvasively, during exercise. This review focuses on the clinical need for diastolic stress testing, both invasively and noninvasively.

舒张压测试：有创和无创测试。

舒张功能障碍是心力衰竭发病机理中的关键因素。大约50％的心力衰竭患者的血流动力学相关性与左心室充盈压增加有关，这是由舒张功能障碍（在明显正常的收缩功能下）引起的。由于其高患病率，舒张功能障碍通常被认为是偶然发现。许多患者具有舒张功能受损的多普勒超声心动图证据，但在静息时没有任何心力衰竭症状。在许多这些患者中，舒张功能障碍的症状仅在运动期间出现，因为在休息时左心室充盈压是正常的，但随着运动而增加。这意味着在运动过程中也应测量充盈压力。舒张压测试是对舒张功能的评估，在运动过程中无论是有创还是无创。这篇综述着重于有创和无创舒张压测试的临床需求。
