The low-density lipoprotein cholesterol-lowering effect of pravastatin and factors associated with achieving targeted low-density lipoprotein levels in an African-American population

The low-density lipoprotein cholesterol-lowering effect of pravastatin and factors associated with achieving targeted low-density lipoprotein levels in an African-American population

Pharmacotherapy 20(12): 1454-1463

Study Objectives. To describe the low-density lipoprotein cholesterol (LDL)-lowering effect of pravastatin in African-American patients and to identify factors associated with achieving National Cholesterol Education Program (NCEP)-defined target levels. Design. Retrospectively defined cohort study. Setting. Large, government-owned, teaching hospital. Patients. Eighty-four African-American patients starting therapy with pravastatin in October-November 1997. Interventions. None. Measurements and Main Results. Whether or not target LDL concentrations were achieved was used to measure efficacy. Stepwise logistic regression identified the target LDL, baseline LDL, and baseline high-density lipoprotein cholesterol (HDL) as significant predictors of achieving the target. The proportion of patients achieving their target LDL when that target was below 160, below 130, and 100 mg/dl or below was 64%, 32%, and 13% (p=0.004), respectively. Medical record review identified the reasons for not achieving target as incorrect drug regimen, inadequate lipid monitoring, and noncompliance. Conclusion. These results indicate that substantial numbers of patients receiving lipid-lowering therapy are not meeting NCEP-defined targets and that with increased drug monitoring and compliance, improvements in achieving NCEP target LDL levels could be realized.
