Key result
V3R/V4R ST elevation in anterior MI is linked to lower LVEF but not increased heart failure.

ST elevation in V3R/V4R lacks prognostic value in anterior STEMI; leaves open whether subtle RV involvement merits prospective validation.
Cohort (n=111)
Does ST segment elevation in leads V3R/V4R predict prognosis in patients with first acute anterior myocardial infarction?
Absolute Event Rate: 22.2% vs 17.9%
p-value: p=0.39
ST elevation in right precordial leads V3R/V4R during acute anterior myocardial infarction is common but does not predict short-term prognosis or MACE, despite being associated with a slightly lower LVEF.
Pourafkari et al. (2016) conducted a cohort in first acute anterior myocardial infarction (n=111). ST segment elevation in leads V3R/V4R vs. Absence of ST elevation in leads V3R/V4R was evaluated on Heart failure (p=0.39). ST elevation in leads V3R/V4R in patients with anterior myocardial infarction was associated with lower LVEF (35% vs 38%, p=0.02) but did not significantly increase heart failure (22.2% vs 17.9%, p=0.39).
