Background: Heart failure with midrange ejection fraction (HFmrEF) represents a heterogeneous category where phenotype, as well as prognostic assessment, remains debated. The present study explores a specific HFmrEF subset, namely those who recovered from a reduced EF (rec-HFmrEF) and, particularly, it focuses on the possible additive prognostic role of cardiopulmonary exercise testing.Methods and Results: We analyzed data from 4535 patients with HFrEF and 1176 patients with rec-HFmrEF from the Metabolic Exercise combined with Cardiac and Kidney Indexes database. The end point was cardiovascular death at 5 years. The median follow-up was 1343 days (25th-75th range 627-2403 days). Cardiovascular death occurred in 552 HFrEF and 61 rec-HFmrEF patients. The multivariate analysis confirmed an independent role of the MECKI score's variables in HFrEF (C-index = 0.744) whereas, in the rec-HFmrEF group, only age and peak oxygen uptake (pVO2) remained associated to the end point (C-index = 0.745). A peak oxygen uptake of ≤55% of predicted and a ventilatory efficiency of ≥31 resulted as the most accurate cut-off values in the outcome prediction.Conclusions: Present data support the cardiopulmonary exercise test and, particularly, the peak oxygen uptake, as a useful tool in the rec-HFmrEF prognostic assessment. A peak VO2 of ≤55% predicted and ventilatory efficiency of ≥31 might help to identify a high-risk rec-HFmrEF subgroup. [ABSTRACT FROM AUTHOR]

To investigate the incremental prognostic significance of malnutrition in patients with severe poststroke disability. Retrospective cohort study. The patients were recruited from 3 specialized inpatient rehabilitation facilities. Nutritional status was assessed using the Prognostic Nutritional Index (PNI), which is calculated from serum albumin and total lymphocyte count. Scores >38 points reflect normal nutrition status, scores of 35-38 indicate moderate malnutrition, and scores <35 indicate severe malnutrition. The association of PNI categories with outcomes was assessed using multivariable regression analyses. Inpatient rehabilitation facility. Patients (N=668) with ischemic stroke admitted to inpatient rehabilitation within 90 days from stroke occurrence and classified as Case-Mix Groups 0108, 0109, and 0110 of the current Medicare case-mix classification system. Not applicable. Three outcomes were examined: (1) the combined outcome of transfer to acute care and death within 90 days from admission to rehabilitation; (2) 2-year mortality; and (3) FIM motor effectiveness, calculated as (FIM motor change/maximum FIM motor−admission FIM motor score)×100. Overall, the median time to rehabilitation admission was 18 days (range, 12-26 days). The prevalence of moderate and severe malnutrition was 12.7% and 11.5%, respectively. Ninety-one patients (13.6%) experienced the combined outcome. After adjusting for independent predictors including sex, atrial fibrillation, dysphagia, FIM cognitive score, and hemoglobin levels, neither moderate (P =.280) nor severe malnutrition (P =.482) were associated with the combined outcome. Similar results were observed when looking at 2-year mortality. Overall, FIM motor effectiveness was 30%±24%. After adjusting for independent predictors, severe malnutrition (β coefficient −0.458±0.216; P =.034) was associated with FIM motor effectiveness. Approximately 1 in every 9 patients presented severe malnutrition. On top of the independent predictors, severe malnutrition did not provide additional prognostic information concerning risk of the combined outcome or 2-year mortality. Conversely, severe malnutrition was associated with poorer functional outcome as expressed by FIM motor effectiveness. • We examined the prognostic role of malnutrition in patients post stroke. • We studied 668 patients with severe ischemic strokes undergoing rehabilitation. • Malnutrition was not associated with clinical outcomes. • Malnutrition was associated with poorer functional outcome after rehabilitation.

Background Obesity has been suggested to confer a survival benefit in acute heart failure. The concentrations of NT-proBNP may be reduced in patients with high body mass index (BMI). Objectives To investigate the relationship among BMI, NT-proBNP, and mortality risk in decompensated chronic heart failure (DCHF). Methods This was a retrospective study. We studied 1001 patients with DCHF. Hazard ratios (HR) were calculated with Cox regression analysis. Results During the 1-year follow-up, 295 patients died. Compared with normal-weight patients, the unadjusted HR for death were 1.02 (95% CIs 0.79–1.33; p = 0.862) for patients with a BMI of 25.0–29.9 kg/m 2 and 0.83 (95% CIs 0.61–1.12; p = 0.213) for patients with a BMI ≥ 30 kg/m 2 . NT-proBNP remained independently associated with mortality across the BMI categories. There was no statistically significant interaction between BMI and NT-proBNP levels for risk prediction. Conclusions Obesity was not associated with mortality risk. NT-proBNP remained an independent prognostic factor across the BMI categories. [ABSTRACT FROM AUTHOR]

Objectives: To assess the incremental prognostic utility of discharge serum creatinine (SCr), systolic blood pressure (SBP), and NT-proBNP and sodium concentrations in hospitalized patients with acutely decompensated chronic heart failure. Background: Whether key prognostic variables at discharge provide incremental prognostic information beyond that provided by a model based on admission variables (referent) remains incompletely defined. Methods: The primary outcome was a composite of death, urgent heart transplantation, or ventricular assist device implantation at 1 year. The gain in predictive performance was assessed using C index, Bayesian Information Criterion, and Net Reclassification Improvement. Results: The best fit was obtained when discharge NT-proBNP was added to the referent model. No interaction between admission and discharge NT-proBNP was found. Discharge SCr, SBP, and sodium did not improve goodness-of-fit. Conclusions: Admission and discharge NT-proBNP provide complementary and independent prognostic information; as such, they should be taken into account concurrently. [ABSTRACT FROM AUTHOR]

• The characteristics and outcomes of patients with heart failure (HF) admitted to inpatient cardiac rehabilitation (CR) are poorly defined. • This lack of knowledge may generate uncertainty about the role of inpatient CR. • Patients admitted to inpatient CR have a poor clinical and functional profile. • In patient CR is effective in improving functional capacity. • In patients with post-acute HF, inpatient CR is associated with improved long-term survival. To investigate the association of cardiac rehabilitation (CR) participation with all-cause mortality after a hospitalization for heart failure (HF) and to describe the characteristics and functional and clinical outcomes of HF patients undergoing inpatient CR. Multicenter cohort study. The association between CR participation and all-cause mortality from discharge from the acute care setting was assessed using Cox regression analysis adjusting for established prognostic factors. Six inpatient rehabilitation facilities. A total of 3219 patients with HF admitted to inpatient CR between January 2013 and December 2016. Of these patients, 1455 had been transferred directly from acute care hospitals after a hospitalization for HF (CR-group 1) and 1764 had been admitted from the community due to worsening functional disability or worsening clinical conditions (CR-group 2). Serving as a control group were 633 patients not referred to CR after a hospitalization for HF served as control group (non–CR group). Cardiac rehabilitation. Long-term mortality. Secondary outcomes were: (1) change in functional capacity, as assessed by change in 6-minute walking distance from admission to discharge; (2) clinical outcomes of the index inpatient rehabilitation admission, including in-hospital mortality and unplanned readmission to the acute care. Compared with the non–CR group, the adjusted hazard ratios of mortality at 1, 3, and 5 years for CR-group 1 patients were 0.82 (range, 0.68-0.97), 0.81 (range, 0.71-0.93), and 0.80 (range, 0.70-0.91). The 6-minute walking distance increased from 230-292 meters (P <.001), and 43.4% of the patients gained >50 m improvement. Overall, 2.5% of the patients died in hospital and 4.7% of the patients experienced unplanned readmissions to acute care, with significant differences between group 1 and group 2. Our data show that inpatient CR is effective in improving functional capacity and suggest that inpatient CR provided in the earliest period after a hospitalization for HF is associated with long-term improved survival.

Objective: To assess the association of high-sensitivity C-reactive protein (hsCRP) to adverse cardiovascular events and perioperative myocardial damage in patients after elective vascular surgery. Methods: This was a prospective observational study in a tertiary-care teaching hospital, with 239 patients undergoing elective vascular surgery. The receiver-operating characteristic (ROC) curve was calculated to assess the optimal cut-off value of hsCRP. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated. Multiple logistic regression analysis was used to identify the predictors of the primary outcome. The primary outcome was a composite of periprocedural myocardial damage, defined as cardiac troponin I (cTn-I) elevation above the decision limit of 0.15 μg/L, death, acute coronary syndrome, stroke, acute heart failure, or intrastent thrombosis within 30 days of surgery. Results: On ROC analysis, the optimal cut-off value of hsCRP was 3.2 mg/L. The primary outcome occurred in 48 patients (20.1%). On univariate analysis, smoking (P = .009), known hypercholesterolemia (P = .01), previous ischemic heart disease (P = .0003), open surgery (P = .03), and hsCRP levels (P < .0001) were associated with the primary outcome. On multiple logistic regression analysis, only hsCRP was independently associated with the primary outcome. The unadjusted and adjusted ORs for the primary outcome among patients with hsCRP levels >3.2 mg/L were 7.5 (CI, 3.7-15.2; P < .0001) and 4.6 (CI, 2.1-9.9; P = .0001), respectively. Conclusion: Our data suggest that higher levels of hsCRP are independently associated with an increased risk of perioperative myocardial damage and early adverse cardiovascular events in patients undergoing elective vascular surgery. This may have implications for risk stratification and therapeutic approach. [ABSTRACT FROM AUTHOR]

In Western countries, the aging and improving survival of patients with coronary heart disease are responsible for an increasing number of older adults (65 years of age and older) who are eligible for cardiac rehabilitation. The elderly with coronary heart disease represent a special population with changes induced by aging and lifestyle, comorbidity, cognitive dysfunction, and high risk of disability. Although the elderly account for the majority of cardiac admissions and procedures, studies on cardiac rehabilitation have traditionally focused on younger patients. In aged experimental animals, there is evidence that exercise training is able to improve hemodynamic parameters and biologic markers. Moreover, in older patients, exercise improves functional capacity and reduces myocardial work, similar to that seen in younger patients. As for younger patients, cardiac rehabilitation requires a multidisciplinary approach, including comprehensive assessment, treatment of risk factors and comorbidity, and psychosocial assessment. Cardiac rehabilitation is safe and helpful for elderly coronary patients. Physicians must be encouraged to prescribe cardiac rehabilitation programs for the elderly following major coronary events and coronary revascularization procedures. [ABSTRACT FROM AUTHOR]

Abstract Objective To characterize rehabilitation outcomes of patients with severe poststroke motor impairment (MI) and develop a predictive model for treatment failure. Design Retrospective cohort study. Correlates of treatment failure, defined as the persistence of severe MI after rehabilitation, were identified using logistic regression analysis. Then, an integer-based scoring rule was developed from the logistic model. Setting Three specialized inpatient rehabilitation facilities. Participants Patients (N=1265) classified as case-mix groups (CMGs) 0108, 0109, and 0110 of the Medicare classification system. Interventions Not applicable. Main Outcome Measure Change in the severity of MI, as assessed by the FIM, from admission to discharge. Results Median FIM-motor (FIM-M) score increased from 17 (interquartile range [IQR] 14-23) to 38 (IQR, 25-55) points. Median proportional recovery, as expressed by FIM-M effectiveness, was 26% (IQR, 12-47). Median FIM-M change was 18 (IQR, 9-34) points. About 38.5% patients achieved the minimal clinically important difference. Eighteen point six percent and 32.0% of the patients recovered to a stage of either mild (FIM-M ≥62) or moderate (FIM-M 38-61) MI, respectively. All between-CMG differences were statistically significant. Outcomes have also been analyzed according to classification systems used in Australia and Canada. The scoring rule had an area under the curve of 0.833 (95% confidence interval, 0.808-0.858). Decision curve analysis displayed large net benefit of using the risk score compared with the treat all strategy. Conclusions This study provides a snapshot of rehabilitation outcomes in a large cohort of patients with severe poststroke MI, thus filling a gap in knowledge. The scoring rule accurately identified the patients at risk for treatment failure. [ABSTRACT FROM AUTHOR]
