Insights
Atorvastatin significantly reduced aortic stiffness in hypercholesterolemia patients over two years. This lipid-lowering treatment may serve as an efficacy marker for cardiovascular health.
Area of Science:
- Cardiology
- Pharmacology
- Vascular Biology
Background:
- Hypercholesterolemia is a significant risk factor for cardiovascular disease.
- Aortic stiffness is an independent predictor of cardiovascular events.
- Statins, like atorvastatin, are primary agents for lipid-lowering therapy.
Purpose of the Study:
- To evaluate the impact of atorvastatin on aortic stiffness.
- To assess changes in lipid profiles and cardiac function.
- To determine if aortic stiffness can guide aggressive treatment in hypercholesterolemia.
Main Methods:
- 36 hypercholesterolemic patients (without hypertension or diabetes) received atorvastatin 20 mg/day for 2 years.
- Aortic stiffness was measured using transthoracic echocardiography at baseline and after 2 years.
- Lipid parameters and left ventricular function were assessed.
Main Results:
- Atorvastatin treatment significantly reduced aortic stiffness by 14% (p=0.019).
- Significant improvements were observed in lipid profiles, including a 46% reduction in LDL-C.
- Left ventricular ejection fraction increased by 13% and LV mass index decreased by 9%.
Conclusions:
- Long-term atorvastatin therapy effectively improves aortic stiffness in hypercholesterolemic patients.
- Aortic stiffness assessment may help identify patients requiring aggressive lipid-lowering treatment.
- Aortic stiffness could become a valuable biomarker for the efficacy of statin therapy.
Aim:
To assess the effect of atorvastatin on aortic stiffness in hypercholesterolaemic patients free of arterial hypertension and diabetes mellitus.
Methods And Results:
The study included 36 patients (25 men and 11 women, mean age 56 +/- 12 years); 18 patients had stable coronary heart disease (CHD) and 18 were free of CHD at baseline. All patients received atorvastatin (20 mg/day) for a 2-year period. Aortic stiffness was assessed by transthoracic echocardiography at baseline and 2 years later. At baseline, total cholesterol, low density lipoprotein cholesterol (LDL-C) and LDL-C/high density lipoprotein cholesterol (HDL-C) ratio were positively related to aortic stiffness (p < 0.001 for all). The mean change in lipid parameters during treatment was: total cholesterol -38%, LDL-C -46%, triglycerides -29%, and HDL-C +6%, all significant (p = 0.029 to < 0.0001). After the 2-year treatment with atorvastatin, aortic stiffness was significantly reduced by 14% (p = 0.019). An improvement of left ventricular (LV) ejection fraction by 13% (p < 0.001) and a reduction of LV mass index by 9% (p = 0.008) were also recorded. The change in aortic stiffness was similar in patients with or without CHD.
Conclusion:
Long-term treatment with atorvastatin improves aortic stiffness; this index is related to total and coronary mortality. Moreover, assessment of aortic stiffness may be useful in identifying which hypercholesterolaemic patients should be treated aggressively, regardless of CHD. The aortic stiffness effect may eventually become an index of the efficacy of lipid lowering treatment.
