Impact of left-ventricular end-diastolic pressure as a predictor of periprocedural hemodynamic deterioration in patients undergoing Impella supported high-risk percutaneous coronary interventions

摘要

An increasing number of high-risk percutaneous coronary interventions (PCI) are performed with mechanical circulatory support (MCS) to minimize the risk of periprocedural hemodynamic compromise. Prior studies have demonstrated that an elevated left-ventricular end-diastolic pressure (LVEDP) is associated with worse outcome after acute myocardial infarction or cardiac surgery. Although LVEDP is frequently measured, little is known about the usefulness for predicting periprocedural hemodynamic deterioration in high-risk PCI. The objective of this study is to assess the impact of preprocedural measured LVEDP in non-shock patients undergoing high-risk PCI with MCS on periprocedural hemodynamic deterioration.
