Efficacy Study of Atorvastatin to Treat Variant Angina (ESAVA)
Study Overview
Detailed Description
Vasospastic angina is presented by myocardial ischemia with spasm of coronary artery accompanying chest pain or discomfort. The precise mechanisms have not been established, but a reduction in NO (nitric oxide) production, an imbalance between endothelium-derived relaxing and contracting factors,or an injury of endothelium have been suggested.
Impaired FMD(flow mediated endothelium-dependent vasodilation) in the brachial artery was demonstrated in vasospastic angina,and improvement of endothelial dysfunction with treatment of statin is documented in several studies.
So, we expect that statin treatment for vasospastic angina provide additional therapeutic effects via improvement of endothelial dysfunction.

Description
Inclusion Criteria:
- Vasospastic angina or spontaneous spasm during coronary angiography (Vasospastic angina is defined as Thrombolysis In Myocardial Infarction (TIMI) flow grade 0-2 noted in intracoronary ergonovine provocation test and development of chest pain or EKG change; Spontaneous spasm is defined as TIMI flow grade 0-2 of coronary artery without ergonovine injection)
- Normal or insignificant lesion (diameter stenosis <50%) on coronary angiography
Exclusion Criteria:
- Elevated liver enzyme: serum aspartate aminotransferase or alanine aminotransferase concentrations more than 3 times the upper limit of normal
- Significant lesion( diameter stenosis ≥50%) documented in coronary angiography
- Pregnancy
- Prior percutaneous coronary intervention or coronary artery bypass surgery
- Previous statin use
- Impaired renal function with serum creatinine ≥ 2.0 mg/dl
- Severe left ventricular dysfunction ( LVEF ≤ 30% on echocardiography)
- Myopathy
