Background
Stable ischemic heart disease (SIHD) is prevalent in patients with chronic kidney disease (CKD); however, whether guideline-directed medical therapy (GDMT) is adequately implemented in patients with SIHD and CKD is unknown.
Hypothesis
Use of GDMT and achievement of treatment targets would be higher in SIHD patients without CKD than in patients with CKD.
Methods
This was a retrospective study of 563 consecutive patients with SIHD (mean age 67.8 years, 84% Caucasians, 40% females). CKD was defined as an estimated glomerular filtration rate (eGFR) of < 60 mL/min/1.73m2 using the four-variable MDRD Study equation. We examined the likelihood of achieving GDMT targets (prescription of high-intensity statins, antiplatelet agents, renin-angiotensin-aldosterone system inhibitors (RAASi), and low-density lipoprotein cholesterol levels < 70 mg/dL, blood pressure < 140/90 mmHg, and hemoglobin A1C < 7% if diabetes) in patients with (n = 166) and without CKD (n = 397).
Results
Compared with the non-CKD group, CKD patients were significantly older (72 vs 66 years; p < 0.001), more commonly female (49 vs 36%; p = 0.002), had a higher prevalence of diabetes (46 vs 34%; p = 0.004), and left ventricular systolic ejection fraction (LVEF) < 40% (23 vs. 10%, p < 0.001). All GDMT goals were achieved in 26% and 24% of patients with and without CKD, respectively (p = 0.712). There were no between-group differences in achieving individual GDMT goals with the exception of RAASi (CKD vs non-CKD: adjusted risk ratio 0.73, 95% CI 0.62–0.87; p < 0.001).
Conclusions
Attainment of GDMT goals in SIHD patients with CKD was similar to patients without CKD, with the exception of lower rates of RAASi use in the CKD group.
