Additional effect of hemodialysis on mortality estimated from renal function in ischemic heart disease.

Aim: The present study examined whether hemodialysis in patients with ischemic heart disease increases mortality more than the estimated mortality from renal function. Patients & methods: A total of 1621 patients with angina pectoris (n = 815), ST-elevation myocardial infarction (n = 421) or non-ST-elevation acute coronary syndrome (n = 385) were examined. An estimated mortality curve according to the estimated glomerular filtration rate was drawn using the marginal effect from the logit model. The probability of mortality in patients with hemodialysis was plotted on these curves. Results: The probability of mortality in patients undergoing hemodialysis crossed the estimated mortality curves at the estimated glomerular filtration rate of 5.7 ml/min/1.73 m 2 in angina pectoris, 31.3 ml/min/1.73 m 2 in STEMI and 45.9 ml/min/1.73 m 2 in non-ST-elevation acute coronary syndrome. Conclusion: Hemodialysis does not have an additional adverse impact on the estimated mortality.
