Abstract 18813: Routine Follow Up Coronary Angiography versus Clinical Follow Up only in Patients Undergoing Elective Percutaneous Coronary Intervention with Drug-eluting Stents
Background: It is unclear whether the routine follow up (FU) coronary angiography (CAG) regardless of patient's symptoms after successful elective percutaneous coronary intervention (PCI) with drug-eluting stents (DESs) in stable patients (pts) excluding acute myocardial infarction (AMI) is beneficial or not.
Methods: The study population consisted of 815 consecutive pts underwent elective PCI with DESs from November 2005 to June 2008. Routine FU CAG was performed between 6 to 9 months following index PCI and was decided by individual physician's discretion. Pts presented with AMI on admission and pts died before 6 months were excluded in both groups. Cumulative clinical outcomes up to 2 years were compared between Routine CAG group (n=549 pts, 76.0%) and Clinical FU group (n= 266 pts, 37.6%).
Results: A total 736 pts (90.3%) were finished clinical follow up to 2 years. Baseline clinical and procedural characteristics were similar between the two groups except Clinical FU group were older and higher incidence of hypertension and cerebral vascular disease (CVD). Although the routine CAG group showed higher incidence of repeat PCI, total death were lower and there a trend toward lower cardiac death up to 2 years as compared with those of clinical FU group. The incidences of stent thrombosis were not different between the two groups (Table).
Conclusions: In our study, routine CAG FU between 6 and 9 months after elective PCI with DESs in stable pts was associated with lower mortality despite of increased repeat PCI up to 2 year. We suggest that routine CAG FU may play an important role in reducing major hard endpoints of pts undergoing elective PCI with DESs.
