Nitrates contraindicated in inferior wall mi
Webb21 feb. 2024 · Nitrates are contraindicated in severe aortic stenosis because of the theoretical yet unproven risk of precipitating profound hypotension. Why nitrates are contraindicated in inferior wall MI? Thus, in the setting of an inferior AMI, a marked hypotensive response to nitrates suggests the presence of RV involvement. WebbNitrates in all forms are contraindicated in patients with Initial systoloic blood pressure 90 mm Hg or 30 mm Hg below baseline and in patients with right ventricular infarction. 40 – 42 Caution is advised in patients with known inferior wall STEMI, and a right-sided ECG should be performed to evaluate RV infarc- tion.
