Gowdak LH, Arantes RL, de Paula FJ, Krieger EM, De Lima JJ: Underuse of American College of Cardiology/American Heart Association Guidelines in hemodialysis patients. Ren Fail. 2007;29(5):559-65.
Patients with end-stage renal disease (ESRD) are at high risk for cardiovascular disease (CVD) and therefore should be treated according to ACC/AHA Guidelines. Scant data are available concerning the actual use of cardioprotective drugs in this population. The use of angiotensin-converting enzyme inhibitors (ACE-I), beta-blockers, aspirin, and statins was assessed in 271 (72% males, 66% Caucasians) high-risk ESRD patients on hemodialysis. The study population comprised 27% smokers, 95% with hypertension, 38% with diabetes, and 44% with dyslipidemia; 44% of patients had overt CVD at baseline, including 9% with heart failure, 9% with prior myocardial infarction, and 3% with previous myocardial revascularization. One-third of all patients were not receiving any cardioprotective drugs; among those patients who were, 42% were on one drug, 21% were on two, 3.7% were on three, and 1.5% were on four. The most prescribed agent was ACE-I (35.8%), followed by aspirin (30.6%), and beta-blockers (28.0%). The use of statins was remarkably and significantly low (4.1%) (p < 0.001), even in the higher risk subgroups (patients with diabetes or macrovascular disease). ACE-I plus aspirin was the most prescribed combination (8.5%). Cardioprotective agents recommended for risk-factor modification by the ACC/AHA Guidelines for their well-established efficacy in the general population were underutilized in this cohort of high-risk hypertensive hemodialysis patients, despite an elevated prevalence of clinically evident CVD. Speculatively, this fact may be relevant to better understand the known increased cardiovascular morbidity-mortality associated with chronic renal disease. |
