REBEL Cast Ep124: Nitrates in Right Sided MIs?

Nitrates, traditionally avoided in patients with right ventricular myocardial infarction (RVMI) due to concerns regarding preload reduction and hypotension, may be safer than current clinical guidelines suggest. A 2023 systematic review and meta-analysis challenges the reliance on a limited 1989 study, finding no statistically significant difference in severe adverse events like cardiac arrest or death when comparing nitrate administration in RVMI patients versus those with other myocardial infarctions. While transient hypotension remains a potential side effect, the short half-life of nitrates allows for rapid management. Given evidence of short-term mortality benefits from earlier research, clinicians might consider a cautious, test-dose approach in normotensive patients. Ultimately, the current contraindication lacks robust evidence, and prioritizing revascularization remains the primary goal in managing these cardiac events.
