The Impact of Blood Pressure Variability on Coronary Arterial Lumen Dimensions as Assessed by Optical Coherence Tomography in Patients with ST-Elevation Myocardial Infarction
Highlights
- • Patients with STEMI treated by primary percutaneous coronary intervention experience drastic blood pressure changes
- • The difference in the infarct-related arterial lumen area between pre- and post-coronary artery stenting is minimal
- • FD-OCT provides reliable luminal measurements despite the extreme hemodynamic changes
Abstract
Background
Patients with ST-elevation Myocardial Infarction treated by primary percutaneous coronary intervention (PPCI) experience drastic hemodynamic systemic changes (i.e., blood pressure) during the different phases of the procedure. Optical coherence tomography is often used to unveil the underlying cause of STEMI (pre-PCI) and to optimize stent implantation (post-PCI). The impact of blood pressure variability on coronary lumen remains uncertain. This study aimed to investigate the relationship between blood pressure variability, before and after PCI, and coronary arterial lumen dimensions of the infarct-related artery.
