Assessing the optimal MAP target in pre-capillary PH patients with RV failure: A retrospective analysis.

Right ventricular failure (RVF) in pre-capillary pulmonary hypertension (PH) is associated with high morbidity and mortality. While mean arterial pressure (MAP) goals have been well established in critical care literature, the optimal MAP target for patients with RVF secondary to pre-capillary PH remains unknown. The objective of this study was to evaluate the difference in outcomes between patients who were managed with different MAP targets. We retrospectively analyzed records of 60 patients who were admitted to the intensive care unit for decompensated RVF secondary to pre-capillary PH. The records were stratified into two groups: 30 patients who were treated with a static MAP goal of either 65 or 70 mmHg (MAP 65/70 ) and 30 patients who received a dynamic MAP goal (MAP CVP ) determined by invasively obtained central venous pressure or right atrial pressure. The dynamic MAP group had a statistically significant decrease in in-hospital mortality and incidence of acute kidney injury compared to the static MAP cohort.
