Abstract
PURPOSE: The current study was to evaluate the gender-disparities in the in-hospital thrombotic and bleeding events among patients with chronic kidney disease (CKD) undergoing percutaneous coronary intervention (PCI). PATIENTS AND METHODS: Patients with CKD undergoing PCI were retrospectively enrolled. Baseline characteristics, and thrombotic and bleeding events occurred during hospitalization were collected and compared by gender. RESULTS: Compared to males (n = 558), females (n = 402) were older and more likely to have diabetes mellitus (37.1% vs 29.7%). Females had a lower estimated glomerular filtration rate (eGFR; 51.2 ± 7.9 vs 54.6 ± 5.1 mL/min/1.73m(2)) and were more likely to undergo urgent PCI (66.7% vs 60.2%) and use glycoprotein IIb/IIIa inhibitor (15.4% vs 7.5%) at peri-PCI period. Compared to males, females had a higher rate of in-hospital mortality which was due to thrombotic events (9.0% vs 3.4%). Females also had a higher rate of moderate-to-severe hemorrhage (8.0% vs 3.2%). After multivariable adjustment, diabetes mellitus (odds ratio [OR] 1.15 and 95% confidence interval [CI] 1.07-1.29) and acute coronary syndrome (ACS) presentation (OR 1.53 and 95% CI 1.34-1.93) were associated with gender-disparities in composite thrombotic events. Ageing (OR 1.10 and 95% CI 1.02-1.33), diabetes mellitus (OR 1.21 and 95% CI 1.07-1.40) and glycoprotein IIb/IIIa inhibitor use (OR 1.13 and 95% CI 1.02-1.28) were associated with composite bleeding events. CONCLUSION: Females with CKD undergoing PCI had a higher risk of experiencing in-hospital thrombotic and bleeding events than males.
