Effect of simvastatin on restenosis after percutaneous transluminal angioplasty of femoropopliteal arterial obstruction

This retrospective observational intravascular ultrasound study evaluated whether simvastatin therapy limits lumen area reduction 1-year after percutaneous transluminal angioplasty (PTA) by reducing reactive plaque growth, reducing reactive vasoconstriction, or both. This study showed that plaque growth is a general response 1 year after PTA regardless of the use of simvastatin; simvastatin has the potential to induce positive vascular remodeling, thereby reducing the occurrence of restenosis.
