Popis: This study was performed to investigate the effects of continuous dosing of oral, trans dermal (patch), and a combination of the two with nitrate treatments on cardiac events in patients with healed myocardial infarction. In total, 1,291 patients with healed myocardial infarction were assigned 2 groups: treatment with nitrates (n = 713) or nontreatment (n = 578). Nitrate treatment was subdivided into 3 groups: patch group (n =149), oral group (n = 504), and combination group (n = 60). The mean observation period was 17.4 ±21.1 months. Primary end points were nonfatal and fatal recurrent myocardial infarction, death from congestive heart failure, and sudden death. Baseline characteristics were also compared among the 4 groups to determine any effects on outcome. Among the patients with patch, oral, and combination groups, cardiac events occurred 3.4%, 6.7%, 10.0%, respectively, whereas only 2.9% of the patients treated without nitrates had cardiac events. The incidence of cardiac events was significantly greater in patients with oral nitrates and combination groups compared to patients without nitrates (p
