Factors influencing dyslipidemia in statin-treated patients in Lebanon and Jordan: results of the Dyslipidemia International Study.

Abstract

Cardiovascular disease is the leading cause of death and disability worldwide. Therefore, as part of the Dyslipidemia International Study (DYSIS), we have analyzed the prevalence of lipid abnormalities and risk factors for dyslipidemia in statin-treated patients in Lebanon and Jordan. This cross-sectional, multicenter study enrolled 617 patients at 13 hospitals in Lebanon and Jordan. Patients were at least 45 years old and had been treated with statins for at least 3 months. Multivariate logistic regression analysis was used to determine patient characteristics contributing to dyslipidemia during statin therapy. Our findings indicated that 55.9percent of statin-treated patients (mean age 60.3 years, 47percent female) in Lebanon and Jordan did not achieve goal levels for low-density lipoprotein cholesterol which were dependent on Systematic Coronary Risk Evaluation (SCORE) risk, and 70percent of patients (76percent men and 63.3percent of women) were at very high cardiovascular risk. Low-density lipoprotein cholesterol goals were not achieved in 67.2percent of those with very high cardiovascular risk. The most commonly prescribed statin was atorvastatin (44.6percent), followed by simvastatin (27.7percent), rosuvastatin (21.2percent), fluvastatin (3.3percent), pravastatin (3percent), and lovastatin (0.2percent). Approximately half of the population was treated with a statin dose potency of 4, equaling 40 mg of simvastatin. In Lebanon and Jordan, the strongest independent associations with low-density lipoprotein cholesterol not at goal were current smoking (odds ratio [OR] 1.96; 95percent confidence [CI] 1.25-3.08), diabetes mellitus (OR 2.53; 95percent CI 1.70-3.77), and ischemic heart disease (OR 2.26; 95percent CI 1.45-3.53), while alcohol consumption was associated with reduced risk (OR 0.12; 95percent CI 0.03-0.57). We observed that many patients in Lebanon and Jordan experienced persistent dyslipidemia during statin treatment, supporting the notion that novel lipid-lowering strategies need to be developed. Also, social programs aimed at combating the extremely high rates of tobacco use and obesity in Lebanon and Jordan are critical for combating cardiovascular disease in these countries.
