Coronary events in obese hemodialysis patients before and after renal transplantation

We examined the impact of obesity (BMI ≥30 kg/m2, n = 357) on prognosis in 1696 hemodialysis (HD) patients before and after renal transplantation (TX). End-points were coronary events, composite cardiovascular (CV) events, and death. Obese HD patients were older (55.9 ± 9.2 vs. 54.2 ± 11), had more diabetes (54% vs. 40%), dyslipidemia (49% vs. 30%), altered myocardial scan (38% vs. 31%), myocardial infarction (MI) (16% vs. 10%), coronary intervention (11% vs. 7%), higher total cholesterol (186 ± 52 vs. 169 ± 47), and triglycerides (219 ± 167 vs. 144 ± 91). Obese undergoing TX had more dyslipidemia (46% vs. 31%), angina (23% vs. 14%), MI (18% vs. 5%), increased total cholesterol (185 ± 56 vs. 172 ± 48), and triglycerides (237 ± 190 vs. 149 ± 100). Obesity was independently associated with coronary events (log-rank = 0.008, HR 2.55% CI 1.27-5.11) and death (log-rank 0.046, HR 1.52, % CI 1.007-2.30) in TX but not in HD. Obese HD patients had more risk factors and ischemic heart disease, but these characteristics did not interfere with prognosis. In TX patients, obesity predicts coronary events and death. © 2015 John Wiley
