Fig. 3From: Right heart size and function significantly correlate in patients with pulmonary arterial hypertension – a cross-sectional studyCourse of stroke volume increase during exercise according to RV area. Patients with smaller (≤ median 20 cm2, dotted line) RV area showed significantly higher SV increase during exercise, than patients with larger RV area (> median 20 cm2; dashed line; mixed ANOVA p < 0.001). Bars indicate the standard errors of the mean differenceBack to article page
