In this study we explore the frequency, type and severity of lung function abnormalities in HFPEF. Methods We measured forced spirometry, static lung volumes, pulmonary diffusing capacity (DLCO) and arterial blood gases in 69 outpatients with newly diagnosed symptomatic HFPEF. Results We found that 94% of the patients showed abnormalities in at least one of the lung function measurements obtained: spirometry was abnormal in 59%, DLCO in 83% and arterial hypoxaemia was present in 62%. Their severity varied between patients, they were more prevalent in patients with NYHA functional P505-15 cell line class III/IV,

and most often they were undiagnosed and untreated. Conclusions Lung function abnormalities are very frequent in HFPEF patients. A greater SHP099 smiles awareness among clinicians may contribute to improve their management and health status.”
“BackgroundUnconscious survivors of out-of-hospital cardiac arrest have a high

risk of death or poor neurologic function. Therapeutic hypothermia is recommended by international guidelines, but the supporting evidence is limited, and the target temperature associated with the best outcome is unknown. Our objective was to compare two target temperatures, both intended to prevent fever. MethodsIn an international trial, we randomly assigned 950 unconscious adults after out-of-hospital cardiac arrest of presumed cardiac cause to targeted temperature management at either 33 degrees C or

36 degrees C. The primary outcome was all-cause mortality through the end of the trial. Secondary outcomes Selleckchem WZB117 included a composite of poor neurologic function or death at 180 days, as evaluated with the Cerebral Performance Category (CPC) scale and the modified Rankin scale. ResultsIn total, 939 patients were included in the primary analysis. At the end of the trial, 50% of the patients in the 33 degrees C group (235 of 473 patients) had died, as compared with 48% of the patients in the 36 degrees C group (225 of 466 patients) (hazard ratio with a temperature of 33 degrees C, 1.06; 95% confidence interval [CI], 0.89 to 1.28; P=0.51). At the 180-day follow-up, 54% of the patients in the 33 degrees C group had died or had poor neurologic function according to the CPC, as compared with 52% of patients in the 36 degrees C group (risk ratio, 1.02; 95% CI, 0.88 to 1.16; P=0.78). In the analysis using the modified Rankin scale, the comparable rate was 52% in both groups (risk ratio, 1.01; 95% CI, 0.89 to 1.14; P=0.87). The results of analyses adjusted for known prognostic factors were similar. ConclusionsIn unconscious survivors of out-of-hospital cardiac arrest of presumed cardiac cause, hypothermia at a targeted temperature of 33 degrees C did not confer a benefit as compared with a targeted temperature of 36 degrees C.
