Abstract
Objectives: Coronary CTO interventions have become a common practice with a prevalence of 3.8-10 % in patients undergoing percutaneous coronary interventions (PCI). There are innumerable studies on CTO interventions. But studies on the patient demographics and background clinical presentations are lacking. This study, planned to bridge this gap. Materials and Methods: This was a single center prospective study of a cohort of all patients undergoing percutaneous coronary intervention (PCI) as elective or adhoc procedure for CTO from august 2014 to june 2015.Only antegrade CTO interventions were included Results: It was a prospective study of a cohort of all patients undergoing PCI as elective or adhoc procedure for CTO. A total of 210 (8.9% of total PCI (2353) during the study period) CTO patients were followed up. The mean age of the patients was 56.54 +/- 8.9 % with 63.3 %(n= 133) below the age of 60 .In the cohort females were only 19% (n= 40).Diabetes mellitus was seen in 33.8%(n= 71) , systemic hypertension in 52.4% (n=110) and 47.1% (n=99) were smokers. In the study 32.9% (n=69) had chronic stable angina(CSA), 22.9 %( n= 48) had UA/NSTEMI and 44.2% (n= 93) had STEMI. Left anterior descending coronary artery (LAD) was involved in 36.7% (n= 77), Right Coronary Artery (RCA) in 48.1% (n= 101), and Left Circumflex Coronary Artery (LCX) in 15.2% (n= 32). The J-CTO score in the cohort was J- CTO<1 in 13.3% (n=28) J- CTO = 2 in 50.5 % (n=106) and J- CTO > 3 in 36.2% (n= 76). Conclusions: This is the first prospective CTO interventional study from Kerala state. Our data shows that Kerala has a relatively younger predominantly males, smokers and hypertensive population having coronary CTOs requiring revascularization. This points to a malignant atherosclerotic tendency in this population and calls for population preventive strategies.
