Patients received an intravenous bolus of the drug followed by 5 hours of intravenous infusion of the drug or a matching placebo. Although tilarginine increased systolic blood pressure by 5 mmHg at 2 hours no effect on mortality was observed at 30 days. There was however a 6 absolute increase in 30-day mortality in the tilarginine group 48 versus 42 in the placebo . This definitive trial gave strong indications for stopping any further trial using nonspecific inhibitors of nitric oxide synthase in cardiogenic shock and possibly also in any other cardiovascular area. The results of the latest large trial in patients with cardiogenic shock CS namely the TRIUMPH trial were recently published in Journal of the American Medical Association 1 . About 6 to 9 of myocardial infarctions MIs mostly with ST elevation is complicated by CS .
