Statin Efficacy and Safety for Lipid Modification in Apparently Healthy Male Military Aircrew

Introduction: Military aircrew men represent an elite group of relatively young, fit, and healthy people. The effectiveness of statin treatment in reducing low-density lipoprotein cholesterol (LDL-C) according to the current National Cholesterol Education Program (NCEP) guidelines, its safety, and compliance in this group of people has not yet been determined. Methods: We prospectively evaluated 84 military aircrew men (mean age 43 Ϯ 7 yr) with LDL-C above the current NCEP guidelines. The patients were divided into two groups according to their coronary risk factors: Group 1, LDL-C goal Ͻ 160 mg ⅐ dL Ϫ1 ; Group 2, LDL-C goal Ͻ 130 mg ⅐ dL Ϫ1 . All patients received statins in addition to therapeutic lifestyle changes and were followed for a mean of 3 Ϯ 1 yr according to a simple flow chart. Lipoprotein levels, liver function tests, creatinine phosphokinase, and subjective adverse reactions were checked periodically. Results: LDL-C significantly declined by 32% (p Ͻ 0.0001) within the first month of treatment and 99% of subjects achieved their LDL-C goal within 114 Ϯ 35 d from statin therapy initiation. The Framingham estimated 10-yr coronary risk showed a reduction at an average of 12 mo after statin therapy initiation from a baseline value of 6.54% to 3.95% (p ϭ 0.003). No subjects were grounded or disqualified from duty, there were no cardiovascular events during follow-up, and compliance to therapy was high [82/84 (98%)]. Discussion: Statin treatment in this highly select, relatively young group of aircrew men significantly and safely lowered LDL-C cholesterol levels
