Abstrakt:	Introduction and Objectives: To analyze the prognostic value of nocturnal hypoxemia measured with portable nocturnal pulse-oximetry in patients hospitalized due to heart failure and its relation to mortality and hospital readmission. Methods: We included 38 patients who were admitted consecutively to our unit with the diagnosis of decompensated heart failure. Pulse-oximetry was considered positive for hypoxemia when more than 10 desaturations per hour were recorded during sleep. Follow-up was performed for 30.3 (standard deviation [SD] 14.2) months, the main objective being a combined endpoint of all-cause mortality and hospital readmission due to heart failure. Results: The average age was 70.7 (SD 10.7) years, 63.3% were males. Pulse-oximetry was considered positive for hypoxemia in 27 (71%) patients. Patients with positive pulse-oximetry had the most frequent endpoint (9.1% [1] vs. 61.5% [16], P = 0.003). After multivariate analysis, continuous nocturnal hypoxemia was related to the combined endpoint (HR = 8.37, 1.19-68.4, P = 0.03). Discussion: Patients hospitalized for heart failure and nocturnal hypoxemia measured with portable pulse-oximeter have an increased risk of hospital readmission and death.
