Experimental as well as clinical data do not support the hypothesis that atorvastatin or any other statin affects the antithrombotic potency of clopidogrel.
Statins have pleiotropic effects: anti-inflammatory, immunomodulatory, antithrombotic, and vascular activity, & may improve left ventricular myocardial function & left ventricular diastolic function by increasing vascular elasticity.
Coronary collateral circulation is associated with preserved myocardial contractility; preexisting collaterals may be more important than neoangiogenesis for angina & MI patients.
