Key result
An RV/LV ratio ≥1 on CTPA was not significantly associated with in-hospital mortality (12.4% vs 12.9%, p=0.908), whereas IVC reflux and increased right atrium and pulmonary artery sizes were significant predictors.
Why the study?
RV dysfunction is the most important cause of mortality in acute PTE, but the correlation between CTPA-detected RV dysfunction parameters and early mortality needed clarification.
Do CTPA parameters and cardiac biomarkers predict in-hospital mortality in patients with acute pulmonary thromboembolism?

Absolute Event Rate: 12.4% vs 12.9%
p-value: p=0.908
In acute pulmonary embolism, RV/LV ratio should be evaluated alongside cardiac biomarkers and other CTPA parameters like IVC reflux to accurately define mortality risk.
CTPA RV parameters may flag early mortality risk in acute PTE; leaves open whether they refine management beyond clinical scores.

Ayöz et al. (2021) conducted an observational in Acute pulmonary thromboembolism (n=206). RV/LV ratio ≥1 vs. RV/LV ratio <1 was evaluated on In-hospital all-cause mortality (p=0.908). An RV/LV ratio ≥1 on CTPA was not significantly associated with in-hospital mortality (12.4% vs 12.9%, p=0.908), whereas IVC reflux and increased right atrium and pulmonary artery sizes were significant predictors.
