Achievement of Therapeutic Goals and Utilization of Evidence-Based Cardiovascular Therapies in Coronary Heart Disease Patients With Chronic Kidney Disease

To evaluate whether the presence of chronic kidney disease (CKD) influenced the rate of prescription of evidence-based cardiovascular preventive therapies and attainment of therapeutic goals in patients with stable coronary heart disease, 7,884 patients (mean age 65.4 years; 81.7% men; 22.4% with CKD) attended to in 1,799 primary-care centers and who had had a coronary event requiring hospitalization in the previous 6 months to 10 years were recruited. Glomerular filtration rate (GFR) was estimated using the MDRD Study equation. Results indicated that patients with CKD received more diuretics (47.6% vs 32.8%; p = 0.034), calcium channel blockers (29.3% vs 23.2%, p = 0.027); and blockers of the angiotensin-renin system (76.4% vs 65.3%; p <0.001). The lower prescription rate of antiaggregants, β blockers, and statins in subjects with CKD did not reach statistical significance in multivariate analysis. A lower percentage of subjects with CKD achieved good control of blood pressure (39.2% vs 65.4%; p <0.001) and glycosylated hemoglobin (43.9% vs 53.4%; p <0.001) relative to patients without CKD. Only 11.8% of patients with CKD had optimum control of all risk factors. Using multivariate analysis, the presence of CKD was inversely related to the degree of risk-factor control, especially in groups with low GFR. In conclusion, patients with stable coronary heart disease and CKD attended to in primary-care centers had poorer control of coronary heart disease risk factors than those with normal GFR despite receiving a similar rate of prescription of evidence-based cardiovascular disease preventive therapies.
