УТИЦАЈ СИМВАСТАТИНА НА РЕГРЕСИЈУ КАРОТИДНЕ АТЕРОСКЛЕРОТСКЕ БОЛЕСТИ

Abstract

Introduction The measurement of intima-media thickness (IMT) of carotid arteries has emerged as the method of choice for determining the anatomic extent of atherosclerosis and assessing cardiovascular progression. Statins are used in the primary and secondary prevention of cardiovascular and cerebrovascular disorders so as to reduce morbidity and mortality.

Objective To evaluate the effects of treatment with simvastatin in patients with elevated cholesterol levels and increased values of carotid arteries IMT.

Methods The study of 275 patients (155 male and 115 female, aged 37-79 years, mean 60.86 years) was performed from January 2008 - January 2010 at the Vascular and Endovascular Surgery Clinic of the Clinical Centre of Serbia. All patients were treated with simvastatin administered once a day for 6 months.

Results Simvastatin treatment resulted in a statistically signuficant decrease of the IMT thickness of the right common carotid artery. There was no statistically significant reduction in the IMT of the left common carotid artery as well as in the IMT of the right and left internal carotid arteries.

Conclusion Long-term simvastatin treatment results in the regression or slowing down atherosclerosis in symptomatic, as well as in asymptomatic patients with a lower grade of carotid stenosis (IMT below 2.5 mm).
