Key result
Using peripheral venous pressure instead of inferior vena cava-based estimation during exercise echocardiography increased the identification of exercise-induced pulmonary hypertension from 40% to 68%.
Why the study?
Exercise stress echocardiography may underestimate pulmonary artery pressures due to difficulty estimating right atrial pressure during exercise, prompting evaluation of peripheral venous pressure as a reliable alternative.
Does peripheral venous pressure-assisted exercise stress echocardiography improve the identification of exercise-induced pulmonary hypertension in patients with suspected HFpEF compared to IVC-based estimation?
Population

May enhance detection of exercise-induced pulmonary hypertension on exercise echocardiography; leaves open effects on outcomes and management.
Observational (n=79)
Does peripheral venous pressure-assisted exercise stress echocardiography improve the identification of exercise-induced pulmonary hypertension in patients with suspected HFpEF compared to IVC-based estimation?
Absolute Event Rate: 68% vs 40%
Peripheral venous pressure measurement during exercise echocardiography provides a more accurate estimation of right atrial pressure, significantly improving the detection of exercise-induced pulmonary hypertension in patients with suspected HFpEF.
A 2022 study conducted an observational in Suspected heart failure with preserved ejection fraction (n=79). Peripheral venous pressure (PVP) measurement vs. Inferior vena cava-based right atrial pressure estimation was evaluated on Proportion of patients with exercise-induced pulmonary hypertension. Using peripheral venous pressure instead of inferior vena cava-based estimation during exercise echocardiography increased the identification of exercise-induced pulmonary hypertension from 40% to 68%.
