Background: Nitrates can help improve symptoms and ischemia in the setting of acute myocardial infarction. Current teaching holds that nitrates should be avoided in patients with potential right ventricular myocardial infarction (RVMI), due to the risk of decreasing preload and precipitating hypotension. This belief is based on a single 1989 study of 40 patients with RVMI and endorsed by both the AHA and ESC guidelines [2]. In that 1989 study, of the 40 patients with RV infarction 20 had a decrease in blood pressure of ≥30mmHg and associated symptoms after the administration of nitrates (SL, Oral, Transdermal, or IV) and 20 did not. The conclusion of this paper was that inferior AMI with RV involvement has a strong association with hypotensive response to nitrates. The major issue is the study is limited by the fact that we are given no information on dosage and multiple routes of administration making clinical application difficult. Better data is needed to guide management. REBEL Cast 124: Nitrates in Right Sided MIs? Click here for Direct Download of the Podcast Paper: Wilkinson-Stokes M et al.
