Su1434 EFFICACY OF MULTI-HOLE SELF-EXPANDABLE METAL STENTS VERSUS FULLY-COVERED SELF-EXPANDABLE METAL STENTS IN PATIENTS WITH UNRESECTABLE MALIGNANT DISTAL BILIARY OBSTRUCTION: A PROSPECTIVE COHORT STUDY WITH PROPENSITY SCORE MATCHING

Abstract Background Cardiac rehabilitation (CR) is a comprehensive disease management program highly recommended by heart failure (HF) guidelines. However, the prognostic effects of outpatient CR are inconsistent among recent meta-analyses which enrolled mainly younger HF with reduced ejection fraction (HFrEF). With an aging population, an increased importance of CR has been put on patients with HF with preserved ejection fraction (HFpEF). Purpose This study aimed to examine the prognostic effects of regularly undergoing CR for 6 months after discharge analysing nationwide cohort data including older population with HFrEF and HFpEF. Methods We analysed 2876 patients who hospitalised for acute HF or worsening chronic HF and capable of walking at discharge in the multicentre prospective cohort study. Frequency of outpatient CR participation of each patient was collected using medical records. We assessed CR frequency within 6 months of discharge since most collaborating hospitals conducted final follow-up examinations at 6 months. The CR group was defined as patients who underwent outpatient CR once or more per week for 6 months after discharge. The main study endpoint was a composite of all-cause mortality and HF rehospitalisation during a 2-year follow-up. We performed a propensity score-matched analysis to compare survival rates between the CR and non-CR groups. Propensity scores for each patient were produced by a logistic regression analysis with the CR group as the dependent variable and 33 potential confounders as independent variables. To evaluate events beyond 6 months, we also conducted landmark analyses at 6 months. Results Of the 2876 enrolled patients, 313 underwent CR for 6 months. After propensity score matching using confounding factors, 626 patients (313 pairs) were included in the survival analysis (median age: 74 years, men: 59.6%, median left ventricular ejection fraction [LVEF]: 42%). During 1006.1 person-years of follow-up, 137 patients were rehospitalised due to HF exacerbation, and 50 patients died in the matched cohort. In Cox proportional hazards model (Figure 1), CR was associated with a reduced risk of composite outcomes (hazard ratio [HR] 0.66; 95% confidence interval [CI] 0.48–0.91), all-cause mortality (HR 0.53; 95% CI 0.30–0.95), and HF rehospitalisation (HR 0.66; 95% CI 0.47–0.92). A subgroup analysis showed similar CR effects in patients with HFpEF (LVEF ≥50%) and HFrEF (LVEF <40%). However, in a landmark analysis, CR did not reduce the adverse outcomes beyond 6 months after discharge (Figure 2). Conclusions The findings of this study demonstrate the needs that CR should become a standard treatment for HF regardless of HF type and the necessity of periodical follow-up after completing CR program to maintain its prognostic effects.

The Difference

ObjectivesWe tested the hypothesis that stroke outcomes in patients with preadmission use of benzodiazepine are worse.MethodIn a prospective cohort study, we recruited patients with acute ischaemic stroke. Mortality, functional outcomes and cognition were evaluated at 8 and 90 days after stroke.Results370 patients were included. 62 (18.5%) of the 336 remaining patients were treated with benzodiazepines when stroke occurred, and they did not receive any other psychotropic drug. The mortality rate was higher in benzodiazepines users than non-users at day 8 (2.2% vs 8.1%, p=0.034) and day 90 (8.1% vs 25.9%, p=0.0001). After controlling for baseline differences using propensity-score matching, only the difference in mortality rate at day 90 was of borderline of significance, with a matched OR of 3.93 (95% CI, 0.91 to 16.98). In propensity-score-adjusted cohort, this difference remained significant with a similar treatment effect size (adjusted OR, 3.50; 95% CI, 1.57 to 7.76). A higher rate of poor functional outcome at day 8 and day 90 defined bymodified Rankin scale (mRS) ≥2 or by theBarthel index (BI) <95 was found in benzodiazepines users. In propensity-score-adjusted cohort, only the difference in mRS≥2 at day 90 remained significant (adjusted OR, 1.89; 95% CI, 1.02 to 3.48). In survivors at day 8 and at day 90, there was no significant difference in cognitive evaluation.ConclusionOur study has shown that preadmission use of benzodiazepines could be associated with increased post-stroke mortality at 90 days. These findings do not support a putative neuroprotective effect of γ-aminobutyric acidAreceptors agonists and should alert clinicians of their potential risks.Trial registration numberNCT00763217.
