Acutely decompensated heart failure with chronic obstructive pulmonary disease: Clinical characteristics and long-term survival.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is among the most common comorbidities in patients hospitalized with heart failure and is generally associated with poor outcomes. However, the results of previous studies with regard to increased mortality and risk trajectories were not univocal. We sought to assess the prognostic impact of COPD in patients admitted for acutely decompensated heart failure (ADHF) and investigate the association between use of ß-blockers at discharge and mortality in patients with COPD. METHODS: We studied 1530 patients. The association of COPD with mortality was examined in adjusted Fine-Gray proportional hazard models where heart transplantation and ventricular assist device implantation were treated as competing risks. The primary outcome was 5-year all-cause mortality. RESULTS: After adjusting for establisked risk markers, the subdistribution hazard ratios (SHR) of 5-year mortality for COPD patients compared with non-COPD patients was 1.25 (95% confidence intervals [CIs] 1.06-1.47; p = .007). The relative risk of death for COPD patients increased steeply from 30 to 180 days, and remained noticeably high throughout the entire follow-up. Among patients with comorbid COPD, the use of ß-blockers at discharge was associated with a significantly reduced risk of 1-year post-discharge mortality (SHR 0.66, 95%CIs 0.53-0.83; p ≤.001). CONCLUSIONS: Our data indicate that ADHF patients with comorbid COPD have a worse long-term survival than those without comorbid COPD. Most of the excess mortality occurred in the first few months following hospitalization. Our data also suggest that the use of ß-blockers at discharge is independently associated with improved survival in ADHF patients with COPD.

Female gender and mortality risk in decompensated heart failure.

BACKGROUND: Still there is conflicting evidence about gender-related differences in prognosis among patients with heart failure. This prognostic uncertainty may have implications for risk stratification and planning management strategy. The aim of the present study was to explore the association between gender and one-year mortality in patients admitted with acute decompensated heart failure (ADHF). METHODS: We studied 1513 patients. The Cumulative Incidence Function (CIF) method was used to estimate the absolute rate of mortality, heart transplantation (HT)/ventricular assist device (VAD) implantation, and survival free of HT/VAD implantation at 1year. An interaction analysis was performed to assess the association between covariates, gender, and mortality risk. Propensity score matching and Cox regression were used to compare mortality rates in the gender subgroups. RESULTS: The CIF estimates of 1-year mortality, HT/VAD implantation, and survival free of HT/VAD implantation at 1year were 33.1%, 7.0%, and 59.9% for women and 30.2%, 10.2%, and 59.6% for men, respectively. Except for diabetes, there was no significant interaction between gender, covariates, and mortality risk. In the matched cohort, the hazard ratio of death for women was 1.19 (95% confidence intervals [CIs]: 0.90-1.59; p=.202). After adjusting for age and baseline risk, the hazard ratio of death for women was 1.18 (95% CIs: 0.95-1.43; p=.127). The use of gender-specific predictive models did not allow improving the accuracy of risk prediction. CONCLUSIONS: Our data strongly suggest that women and men have comparable outcome in the year following a hospitalization for ADHF.

Tricuspid Annular Plane Systolic Excursion in Acute Decompensated Heart Failure: Relevance for Risk Stratification.

BACKGROUND: Although the prognostic value of right ventricular dysfunction in chronic heart failure (HF) has been studied extensively, it remains insufficiently characterized in the setting of acute decompensated HF (ADHF). We sought to assess whether measurement of tricuspid annular plane systolic excursion (TAPSE) or TAPSE-to-estimated pulmonary arterial systolic pressure (ePASP) ratio allows improvement of risk prediction in ADHF. METHODS: Four hundred ninety-nine patients with ADHF were studied. Cox regression analyses were used to analyze the association of TAPSE and TAPSE-to-ePASP ratio with 1-year mortality and logistic regression analyses to analyze the association of the 2 variables of interest with adverse in-hospital outcome (AiHO) (in-hospital death plus worsening HF). RESULTS: During the 365-day follow-up, 143 patients (28.7%) died. At univariable analysis, both TAPSE (P = 0.026) and TAPSE-to-ePASP ratio (P < 0.0001) were significantly associated with 1-year mortality. At multivariable Cox analysis, age (P = 0.0270), ischemic heart disease (P = 0.020), systolic blood pressure (P = 0.006), log N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels (P < 0.0001), serum sodium levels (P = 0.001), and hemoglobin levels (P = 0.001) at admission were independently associated with 1-year mortality. Adjusting for these covariates, neither TAPSE (P = 0.314) nor TAPSE-to-ePASP ratio (P = 0.237) remained independently associated with 1-year mortality. Eighty-three patients (16.6%) had an AiHO. At multivariable logistic regression analysis, the TAPSE-to-ePASP ratio was independently associated with an AiHO (P = 0.024). The association of TAPSE alone or ePASP alone was not statistically significant. CONCLUSIONS: Our data strongly suggest that early assessment of TAPSE or TAPSE-to-ePASP ratio does not improve prediction of 1-year mortality over other key risk markers in ADHF. Nonetheless, the TAPSE-to-ePASP ratio did appear to be independently associated with AiHO.
