Insights
Unprotected left main coronary artery intervention may improve left ventricular reverse remodelling in patients with coronary artery disease and reduced ejection fraction. Prior PCI and restenosis were associated with poorer outcomes.
Area of Science:
- Cardiology
- Interventional Cardiology
- Cardiovascular Imaging
Background:
- Percutaneous coronary intervention (PCI) is an alternative to surgical revascularization for coronary artery disease (CAD).
- Predictors of left ventricular reverse remodelling (LVRR) after PCI in patients with reduced left ventricular ejection fraction (LVEF) are not well-defined.
Purpose of the Study:
- To identify determinants of LVRR following PCI in patients with CAD and reduced LVEF.
Main Methods:
- Analysis of 286 patients with LVEF < 50% who underwent PCI.
- LVRR defined as LV end-systolic volume reduction ≥ 15% and LVEF improvement ≥ 10% at 6-month follow-up.
- Multivariate logistic regression used to identify predictors of LVRR.
Main Results:
- Unprotected left main coronary artery (LMCA) intervention was significantly associated with LVRR (OR 4.70).
- Prior PCI (OR 0.35), in-stent restenosis (OR 0.32), and de-novo stenosis (OR 0.36) were negatively associated with LVRR.
Conclusions:
- Unprotected LMCA intervention may offer prognostic benefits for LVRR in CAD patients with LV systolic dysfunction.
- Regular angiographic follow-up is crucial for patients with CAD and LV systolic dysfunction.
Abstract:
Percutaneous coronary intervention (PCI) is sometimes considered as an alternative therapeutic strategy to surgical revascularization in patients with coronary artery disease (CAD) and reduced left ventricular ejection fraction (LVEF). However, the types or conditions of patients that receive the clinical benefit of left ventricular reverse remodelling (LVRR) remain unknown. The purpose of this study was to investigate the determinants of LVRR following PCI in CAD patients with reduced LVEF. From 4394 consecutive patients who underwent PCI, a total of 286 patients with reduced LV systolic function (LVEF < 50% at initial left ventriculography) were included in the analysis. LVRR was defined as LV end-systolic volume reduction ≥ 15% and improvement of LVEF ≥ 10% at 6 months follow-up left ventriculography. Patients were divided into LVRR (n = 63) and non-LVRR (n = 223) groups. Multivariate logistic regression analysis revealed that unprotected left main coronary artery (LMCA) intervention was significantly associated with LVRR (P = 0.007, odds ratios [OR] 4.70, 95% confidence interval [CI] 1.54-14.38), while prior PCI (P = 0.001, OR 0.35, 95% CI 0.19-0.66), presence of in-stent restenosis (P = 0.016, OR 0.32, 95% CI 0.12-0.81), and presence of de-novo stenosis (P = 0.038, OR 0.36, 95% CI 0.14-0.95) were negatively associated with LVRR. These data suggest the potential prognostic benefit of unprotected LMCA intervention for LVRR and importance of angiographic follow-up in patients with CAD and LV systolic dysfunction.
