The composite ischemic endpoint in this study was death, recurrent MI, stroke, or unplanned PCI due to unstable angina. As controls served 25 patients without atherosclerotic lesions in coronary angiography despite positive stress tests for ischemia, similar to the MI group in terms of demographics, cardiovascular risk factors and comorbidities. Results In the first study, following ischemia median citrulline\/arginine index decreased when compared with 6\-month result \(P=0,002\). Baseline median concentrations of arginine, citrulline, ornithine and asymmetric dimethylarginine \(ADMA\) were correlated with ratios of AAR\/LV and IS\/LV. The concentrations of arginine \(P=0,021\) and ADMA \(P=0,009\) were higher but NOx \(P=0,003\) was lower in patients with MVO when compared to subjects without MVO. By Cox regression, arginine concentration lower <29 μM as measured 6 months following MI adjusted to age, sex and IS was independently associated with 2,5 more frequent composite endpoint including death, recurrent MI or heart failure hospitalization during 5\-year follow\-up. The results of the second study showed that during acute ph"]
