Reversibility of Precapillary Pulmonary Hypertension and Outcomes After Heart Transplantation Bridged with Left Ventricular Assist Devices: Insight from the UNOS.
In light of the updated lowered threshold for diagnosing pulmonary hypertension (PH), the reversibility of precapillary PH with left ventricular assist device (LVAD) and the associated post-heart transplantation (HT) outcomes remain unclear. ⋯ Many recipients of HT bridged with LVAD remain with PVR >2 after LVAD implantation, which is associated with increased risk of death after HT compared with patients with normalized PVR after LVAD.

Percent predicted peak oxygen uptake is superior to weight-indexed peak oxygen uptake in risk stratification before lung cancer lobectomy.
To improve preoperative risk stratification in lung cancer lobectomy by identifying and comparing optimal thresholds for peak oxygen uptake (VO2peak) presented as weight-indexed and percent of predicted values, respectively. ⋯ This study showed that weight-indexed VO2peak was of less use as a marker of risk at the lower range of exercise capacity, whereas % predicted VO2peak was associated with a continuously increasing risk of major complications, also at the lower end of exercise capacity. As identifying subjects at high risk of complications is important, % predicted VO2peak is therefore preferable.
