These distinctions could underlie differences in disease mechanisms and necessary treatment approaches, according to a recent study.

Plasma volume status (PVS) — an indirect, non-invasive measure of heart congestion — is a predictor of short-term hospital stays and mortality outcomes in people with multiple types of pulmonary hypertension (PH), a study reported. According to the researchers, plasma volume could be used to monitor…
