Key result
Echocardiographic assessment revealed that RV longitudinal strain had a significant negative correlation with Killip class and LV ejection fraction (r2 = 0.803, P = 0.001).
Why the study?
Assessment of right chamber function has been underemphasized due to complex anatomy and visualization difficulties, leading to a poor understanding of RV function's prognostic impact in AMI exclusive of RV infarction.
Does echocardiographic assessment of RV function correlate with LV dysfunction and Killip class in patients with acute myocardial infarction?

Does echocardiographic assessment of RV function correlate with LV dysfunction and Killip class in patients with acute myocardial infarction?
Effect estimate: r2 = 0.803
p-value: p=0.001
In patients with acute myocardial infarction, RV longitudinal strain correlates significantly with LV ejection fraction and Killip class, suggesting it is a sensitive marker for RV dysfunction.
No takes yet. Share an insight, caveat, or question.
RV strain may refine early prognostication in AMI; extends evidence on RV-LV interplay beyond conventional echo parameters.
Lohitashwa et al. (2023) conducted a cross-sectional in Acute myocardial infarction (AMI) exclusive of RV infarction (n=21). Echocardiographic assessment of right ventricular function was evaluated on Relation between RV function and left ventricle (LV) dysfunction and Killip class (r2 = 0.803, p=0.001). Echocardiographic assessment revealed that RV longitudinal strain had a significant negative correlation with Killip class and LV ejection fraction (r2 = 0.803, P = 0.001).
