Risk factors for coronary artery disease in patients with renal failure.

Cardiovascular mortality is markedly increased in patients with end-stage renal disease (ESRD), particularly those receiving dialysis. Coronary artery disease is the most important cause of death in these patients. As in the general population, older age, male gender, and the postmenopausal state in women are cardiovascular risk factors in patients with ESRD. However, hypertension, diabetes mellitus, and dyslipidemia, known to promote cardiovascular disease in the general population, are particularly likely to do so in patients with ESRD because of their high prevalence in this population. In addition, nontraditional cardiovascular risk factors, such as hyperhomocystinemia, inflammation, elevated calcium x phosphate product, endothelial dysfunction, and oxidant stress, occur frequently in patients with ESRD. Vigorous treatment of modifiable cardiovascular risk factors has reduced cardiovascular risk in patients without ESRD. The extent to which such risk factor modification would alter cardiovascular risk in ESRD remains uncertain.
