Background: We aimed to assess the relationship between echocardiographic characteristics and mortality in patients with chronic obstructive pulmonary disease (COPD). Methods: We prospectively studied 154 patients (mean age 71 ± 10 years, 71% male) with COPD. All patients underwent transthoracic Doppler echocardiography within 48 hours of hospital admission. Primary endpoint was all-cause mortality during a median period of 22 months. Results: Mildly elevated tricuspid regurgitation pressure and mitral E/e′ ratio were the most commonly encountered echocardiographic abnormalities, observed in 60% and 56% of patients, respectively. In Kaplan-Meier analysis of survival, left atrial enlargement, E/e′ ratio > 8, right atrial enlargement, right ventricular dilation, decreased tricuspid annular plane systolic excursion, decreased tricuspid annular systolic velocity, and elevated tricuspid regurgitation velocity were associated with all-cause mortality (p < 0.05 for all). In the Cox proportional hazards analysis, the mitral E/e′ ratio (hazard ratio 1.048; 95% confidence interval 1.001–1.096) remained an independent echocardiographic predictor of survival after adjustment for age, COPD severity, and other baseline echocardiographic parameters. Conclusions: Among patients with COPD, an abnormal mitral E/e′ ratio was an independent echocardiographic predictor of all-cause mortality. Echocardiographic evaluation of structural and functional cardiac abnormalities provides important prognostic information and should be used routinely in the assessment of patients with COPD. © 2016 Wiley Periodicals, Inc.

Heart failure (HF) is a rapidly growing public health problem and the leading cause of morbidity, mortality, and hospitalization in populations > 65 years. The elderly HF patients have an increased prevalence of HF with preserved ejection fraction and comorbidities, may present with atypical symptoms and signs, have a higher risk for adverse drug reactions, and worse prognosis as compared with younger patients. Moreover, there is a lack of evidence-based therapies for this population because they are underrepresented in the clinical trials. The elderly are less likely to be evaluated by a cardiologist and to be treated in accordance with recommendations of the current HF guidelines. Although the treatment is improving, it is still suboptimal; therefore, HF in elderly patients requires mobilization of public health services and improvement of treatment strategies. © 2016, Springer-Verlag Wien.

Diagnosing heart failure with preserved ejection fraction (HFpEF) in patients with chronic obstructive pulmonary disease (COPD) is difficult due to overlapping pathophysiological pathways, risk factors and clinical presentations. We investigated the prevalence and prognostic implications of coexisting HFpEF in patients hospitalized for acute exacerbation of COPD. A total of 116 consecutive patients with an acute exacerbation of COPD were evaluated for HFpEF and followed for an average period of 22 ± 9 months for the occurrence of death from any cause. HFpEF was diagnosed in 22 (19 %) patients with COPD, who were older, and also had higher LV mass, left atrial size, and mitral E/Ea ratio than those without HFpEF (p < 0.05 for all comparisons). HFpEF was not independently associated with all-cause mortality [hazard ratio (HR) 1.07, 95 % confidence interval (CI) 0.44–2.62]. Global initiative for chronic Obstructive Lung Disease (GOLD) stage (IV vs. I–III, HR 2.37, CI 1.23–4.59) and N-terminal pro B-type natriuretic peptide (NT-proBNP) levels (HR 2.79, CI 1.12–6.98) were independent predictors of long-term survival. HFpEF is present in one-fifth of patients with exacerbated COPD. Non-invasively diagnosed HFpEF may not be an independent predictor of all-cause mortality. Elevated NT-proBNP levels and very severe COPD were independently associated with unfavorable overall survival. © 2015, SIMI.

Background: Self-rated health (SRH) predicts outcome in patients with heart failure. Beta-blockers are known to improve health-related quality of life and reduce mortality in such patients. We aimed to evaluate the relation between SRH and adverse events during titration of beta-blockers in elderly patients with heart failure. Methods: The cardiac insufficiency bisoprolol study in the elderly (CIBIS-ELD) is a multicentre, double-blind trial, in which 883 patients aged ≥ 65 years with chronic heart failure (73 ± 6 years, 38% women, left ventricular ejection fraction [LVEF] 42% ± 14%) were randomised to bisoprolol or carvedilol. SRH was assessed at baseline and after 12 weeks, using a 5-grade descriptive scale: excellent, very good, good, fair, and poor. Results: Median SRH at baseline and follow-up was good, but more patients reported fair/poor SRH at baseline (36% vs. 30%, p = 0.012). Women, beta-blocker-naïve patients, patients in NYHA class III/IV and those with PHQ-9 score ≥ 12 were more likely to report fair/poor baseline SRH (p < 0.001 for all). During follow-up, SRH improved in 34% of patients and worsened in 8% (p < 0.001). Adverse events were experienced by 64% patients and 38% experienced > 1 adverse event or serious adverse event, with higher prevalence in lower SRH categories. In a multivariate logistic regression model, SRH, age, distance achieved on the 6-min walk test and LVEF > 45% predicted adverse events (p < 0.05 for all). Conclusions: SRH is an independent predictor of adverse events during titration of beta-blockers and correlates with the proportion and number of adverse events per patient. © 2011 Elsevier Ireland Ltd.
