Predictors of procedural success among Filipino patients who underwent multi-vessel percutaneous coronary intervention

ABSTRACT

BACKGROUND: The leading cause of mortality in the country is heart disease with a rate of 94.5 deaths per 100,000 Filipinos. Multi-vessel coronary artery disease (MV-CAD) patients carry an increased procedural risk especially those with increased lesion complexity or unfavorable anatomy.OBJECTIVE: The study aims to determine the variables that will predict procedural success and clinical outcome among MV-CAD patients undergoing percutaneous coronary interventionSETTING: Philippine Heart Center, Quezon City, PhilippinesMETHODOLOGY: This retrospective cohort study obtained data from the four-year Philippine Heart Center Registry consisting of 1,030 patients who underwent Multi-Vessel Percutaneous Coronary Intervention (MVPCI) from January 2009 to January 2012 at the Cardiac Catheterization Laboratory.RESULTS: Significant predictors for improved procedural success and reduced risk for major cardiovascular events was evident in male patients, those with mild diastolic dysfunction (grade I or II) and patients on statin therapy. The variables with unfavorable procedural and clinical outcome are female patients, those with unstable angina, STEMI, heart failure, COPD, the need for IABP counterpulsation and a left main artery coronary lesion.CONCLUSION: The results reflect a local "real-life scenario" providing important information on the predictors of outcome among Filipino patients with multi-vessel disease undergoing percutaneous coronary intervention. The information obtained is clinically relevant for both cardiologist and interventionist providing an important risk stratification and contributing to the holistic delivery of cardiovascular care.
