Abstract 15183: Do Two Scoring Systems of Coronary Stenosis, Syntax Score and Gensini Score, Similarly Predict Clinical Outcome After Pci in Patients With Stable Angina Pectoris?

Background: Few studies have examined if two scoresystems of coronary stenosis, SYNTAX scoreand Gensini score, are different as predictors of prognosis in patients with coronary artery disease (CAD). Here we examined this issue in patients with stable CAD after percutaneous coronary intervention (PCI). Methods: We retrospectively analyzed 795 consecutive patients who underwent coronary angiography for suspected stable CAD from January 2007 to August 2012. One hundred fifty-nine patients received PCI according to consensus of the Heart Team in our institute and patients’ consents. Overall severity of coronary stenosis and complexity in each patient was quantified by both the SYNTAX scoreand Gensini score, and patients were divided into high scoregroup and low scoregroup by the mean of the scorein overall patients. Follow-up period was 15.9 ± 14.4 months, and MACEwas defined as a composite of cardiac death, myocardial infarction, target vessel revascularization and/or congestive heart failure. Results: The mean SYNTAX scoreand Gensini scorewere 19.0 ± 12.4 and 47.8 ± 26.9, respectively. Long-term MACEin a group with high SYNTAX score(≧19, n=71) tended to be higher than a group with low SYNTAX score( Conclusion: Gensini scoreis not inferior to SYNTAXin prediction of the clinical outcome after PCI in patients with stable CAD. Prognosis after PCI is favorable in patients with low Gensini score(especially those with GS
