Why the study?
CMR-based feature tracking can detect LV strain abnormalities in PH, but little is known about the prognostic value of LV function and mechanics in these patients.
Does left ventricular global longitudinal strain measured by cardiovascular magnetic resonance feature tracking predict mortality in patients with precapillary pulmonary hypertension?
Population
43 patients with precapillary PH referred for CMR
Comparison
Survival vs non-survival groups
Design

LV GLS by CMR-FT may refine risk stratification in precapillary PH; leaves open whether it adds incremental value beyond RV parameters in prospective models.
Does left ventricular global longitudinal strain measured by cardiovascular magnetic resonance feature tracking predict mortality in patients with precapillary pulmonary hypertension?
Left ventricular global longitudinal strain measured by CMR feature tracking is a strong predictor of mortality in patients with precapillary pulmonary hypertension.
