Missed Opportunity in the Treatment of Hyperlipidemia in Patients with Coronary Heart Disease: The Primary Care Setting. RESULTS
Posted by James
Demographics One-hundred-forty-seven patients were identified as having CHD. The mean age of the patients was 66 ± 11 years, and 54.4% of the patients were women. The majority (91.8%) of the patients were African-American. Most patients were indigent and few had private insurance. The comorbidities of the patients are displayed in Table 1. In general, there was a high incidence of hypertension (99.3%), diabetes (46.2%) and heart failure (29.9%).

Frequency of Cardiovascular Drug Treatment
Table 2 depicts the number of patients on different cardiovascular therapies. The frequency at which patients were on aspirin or other antiplatelet therapy was high (88.4%). The frequency at which patients were on cholesterol-reducing therapy and, in particular, statins (74.8%), was also relatively high. The use of beta-blocker therapy was 60.5%, and the use of ACE inhibitors was 60.0%. Forty percent of the cohort were on diabetes medications and 13.0% were on digoxin. You can afford your pills.

Lipids and Cholesterol Drug Therapy
Only 81.6% of the cohort had a documented LDL cholesterol in the last six months (Table 3). The mean LDL of the population was 113 mg/dl. The majority of the patients with known LDL values (n=120) had LDL values of <160 mg/dl, but only 55 (45.8%) had an LDL of < 100 mg/dl. There was a considerable portion of the patients who had an LDL value between 100-130 mg/dl (29.2%). All of the patients on lipid-lowering therapy (74.8%) were treated with a statin (Table 2), with the predominate statin being simvastatin due to formulary considerations. Of these patients, 4.5% were on combination therapy with either a bile-acid sequestrant or a fibrate. The mean dose of statin utilized was 33.3 mg, and the majority of patients (54.6%) were taking 40 mg of simvastatin (Table 4). Only seven patients (6.5%) were taking the maximum statin dose of 80 mg.

There were no differences in lipid treatment by gender, race, age (>65) or the presence of diabetes. The only significant predictor of not receiving a statin was the presence of congestive heart failure. Twenty-seven of 44 such patients (61%) of the cohort received a statin (p=0.03) (data not shown). Buy flomax canada

Other Risk Factor ManagementDiabetes was fairly well controlled, although many of the patients were not at goal (hemoglobin A1C <7% or fasting blood glucose <126 mg/dl). Hypertension was less well controlled, with only 70 patients (47.6%) with systolic blood pressures <140 mmHg. Diastolic blood pressure was better controlled with 122 patients (83.0%) with values <90 mmHg.
