Retrospective Study of Clinical and Epidemiological Parameters of Patients Undergoing Percutaneous Coronary Intervention with Their Follow-Up

Abstract

AIM: To study clinical and epidemiological parameters of patients undergoing percutaneous coronary intervention (PCI) and to follow them up for understanding the outcomes of the procedure.
 MATERIAL AND METHODS: This is a retrospective data analysis of 862 patients who underwent PCI from January 2016 to November 2017
 RESULTS: Out of 862 patients, 611 (70.88%) were male & 251 (29.12%) were female, with the mean age being 55. 243 (28.19%) were diabetic, 470 (54.52%) were hypertensive, 158 (18.32%) patients were tobacco chewer, 215 (24.92%) were smokers and 111 (12.87%) were alcoholic. 636 (73.78%) patients had STEMI, 153 (17.74%) had NSTE-ACS, 61 (7.07%) had CSA.578 (67.05%) were SVD, 262 (30.39%) were DVD and 19 (2.20%) were TVD. Out of SVD, 350 (60.55%) patients had LAD involvement and among DVD patients, LAD and RCA were most commonly involved in 107 (40.83%) patients. On follow-up of mean 604.42 days (minimum 236 days, maximum 909 days), 2 (0.23%) episodes of subacute stent thrombosis occurred and 11 (1.27%) patients had ISR but no mortality was reported.
 CONCLUSION: The study shows affection of young population predominately and genders inequality, suggesting primarily male disease. PCI is often sought in ACS and CSA is predominately treated medically. Thrombolysis remains the first treatment received by STEMI patients. SVD is the most common angiographic diagnosis with LAD predominately affected vessel. This real world-data on clopidogrel with aspirin as dual antiplatelet therapy and second-generation stent shows negligible event of stent thrombosis and ISR.
 LIMITATION: Due to non-invasive follow-up, the exact amount of stent restenosis cannot be calculated.
 IMPACT ON DAILY PRACTICE: This real world-data on clopidogrel with aspirin as dual antiplatelet therapy and second-generation stent shows negligible event of stent thrombosis and ISR. This can help reduce the cost burden on society and help better distribution of health budget.
