Key result
Higher LV-to-RV global longitudinal strain ratio is linked to increased mortality in isolated LV MI.
Why the study?
Does a higher cardiac MRI-derived left-to-right global longitudinal strain ratio predict all-cause mortality in patients with isolated left ventricular ST-elevation myocardial infarction?
Population
Patients with isolated left ventricular myocardial infarction
Comparison

Does a higher cardiac MRI-derived left-to-right global longitudinal strain ratio predict all-cause mortality in patients with isolated left ventricular ST-elevation myocardial infarction?
Cardiac MRI-derived left-to-right global longitudinal strain ratio may serve as a prognostic marker for all-cause mortality in patients with isolated left ventricular STEMI.
Zhao et al. (2026) studied this question. A higher left-to-right ventricular global longitudinal strain ratio was independently associated with increased risk of all-cause mortality in isolated left ventricular myocardial infarction.
