RESUMEN
Objective: Registry-based prospective study was conducted to evaluate association of body mass index (BMI) with major adverse coronary events (MACE) following percutaneous coronary intervention (PCI). Methods: Successive patients undergoing PCI were enrolled from April'19 to March'22 and classified into five BMI categories (<23.0,23.0-24.9,25.0-26.9,27.0-29.9, and ≥30.0 kg/m2). Clinical, angiographic features, interventions and outcomes were obtained by in-person or telephonic follow-up. Primary endpoints were (a) MACE(cardiovascular deaths, acute coronary syndrome or stroke, revascularization, hospitalization and all-cause deaths) and (b)cardiovascular deaths. Cox-proportionate hazard ratios(HR) and 95 % confidence intervals(CI) were calculated. Results: The cohort included 4045 patients. Mean age was 60.3 ± 11y, 3233(79.7 %) were men. There was high prevalence of cardiometabolic risk factors. 90 % patients had acute coronary syndrome(STEMI 39.6 %, NSTEMI/unstable angina 60.3 %), 60.0 % had impaired ejection fraction(EF) and multivessel CAD. Lower BMI groups (<23.0 kg/m2) had higher prevalence of tobacco use, reduced ejection fraction(EF), multivessel CAD, stents, and less primary PCI for STEMI. There was no difference in discharge medications and in-hospital deaths. Median follow-up was 24 months (IQR 12-36), available in 3602(89.0 %). In increasing BMI categories, respectively, MACE was in 10.9,8.9,9.5,9.1 and 6.8 % (R2 = 0.73) and CVD deaths in 5.1,4.5,4.4,5.1 and 3.5 % (R2 = 0.39). Compared to lowest BMI category, age-sex adjusted HR in successive groups for MACE were 0.89,0.87,0.79,0.69 and CVD deaths 0.98,0.87,0.95,0.75 with overlapping CI. HR attenuated following multivariate adjustments. Conclusions: Low BMI patients have higher incidence of major adverse cardiovascular events following PCI in India. These patients are older, with greater tobacco use, lower EF, multivessel CAD, delayed STEMI-PCI, and longer hospitalization.
RESUMEN
BACKGROUND & AIMS: To determine variations in coronary artery disease (CAD) clinical presentation, interventions, and outcomes in patients with diabetes vs without, a prospective study was performed. METHODS: Successive patients with predominantly acute coronary syndromes who underwent percutaneous coronary intervention (PCI) were enrolled from January 2018 to March 2021. Patients with diabetes were compared to those without diabetes to determine differences in clinical and angiographic features and outcomes. In-person and telephonic follow-up were performed. Primary outcome was cardiovascular death and co-primary were major adverse cardiovascular events (cardiovascular death, myocardial infarction, revascularization, stroke). Cox-proportional hazard ratios (HR) and 95% confidence intervals (CI) were calculated. RESULTS: 5181 patients (men 4139,women 1042) were enrolled. Acute coronary syndrome(ACS) was in 4917 (94.9%) and diabetes in 1987 (38.4%). Patients with diabetes were older (61.1 ± 9.6 vs 59.7 ± 11.5years), with more hypertension (71.1 vs 45.5%), chronic kidney disease (3.0 vs 1.7%), previous PCI (13.5 vs 11.0%), past coronary artery bypass graft surgery (4.9 vs 2.4%), non ST-elevation myocardial infarction (59.6 vs 51.6%) and triple vessel disease (20.3 vs 17.2%) (p < 0.01). Duration of hospitalization was more in diabetes (4.2 ± 2.6 vs 4.0 ± 2.1 days, p = 0.023) with no difference in in-hospital deaths (1.4 vs 1.0%, p = 0.197). Follow up was performed in 1202 patients (diabetes 499,41.5%) enrolled from April 2020 to March 2021 (median 16.4 months). In diabetes there were more cardiovascular deaths (multivariate adjusted HR 2.38, CI 1.13-5.02) and all-cause deaths (HR 1.85, CI 1.06-3.22). CONCLUSIONS: CAD patients with diabetes undergoing PCI have more hypertension, chronic kidney disease, non ST-elevation myocardial infarction and triple vessel disease. At medium-term follow-up the incidence of cardiovascular and all-cause deaths is significantly more in these patients.
