Isovolumic relaxation intraventricular pressure difference predicts elevated left ventricular end-diastolic pressure in patients with coronary artery disease.

ABSTRACT: Current guideline for evaluating diastolic function requires multiple parameters to identify patients with elevated left ventricular end-diastolic pressure (LVEDP). However, the intermediate result still exists and may cause LVEDP undetermined. Previous studies have shown intraventricular pressure difference (IVPDs) are required for normal LV filling, but the relationship between IVPDs and LVEDP is unknown. In this study, we analyzed the relationship between IVPDs and LVEDP in 54 patients with coronary artery disease (CAD). LVEDP was prospectively measured at the time of coronary intervention and LVEDP > 15 mmHg was considered as elevated LV filling pressure. Simultaneous echocardiographic data was collected prior to the intervention. The relative intraventricular pressure was calculated u
