Open reduction of carpometacarpal fracture dislocations: a case report

Dislocations of the carpometacarpal (CMC) joints are uncommon injuries. Up to 70% of carpometacarpal dislocations are missed or misdiagnosed. Post traumatic dislocation of carpal and CMC joint results most commonly due to high energy trauma. A 24 year old male with right hand dominant presented 5 days after in emergency room with alleged history of fall from 4 feet height on right hand with wrist in extension. On clinical examination revealed marked swelling over dorsum of right hand with wound over volar aspect of hand. There was minimal movement of fingers due to pain. There was no finger paresthesia. CRT was normal. Radiography revealed a volar dislocation of 2nd to 5th CMC joint with intra-articular fracture of base of proximal phalanx of the thumb. He was treated by open reduction and percutaneous fixation using Kirschner wires. The functional results were excellent at 6 months of follow-up

Effects of sacubitril/valsartan on N-terminal pro-B-type natriuretic peptide in heart failure with preserved ejection fraction

Objectives: The authors sought to evaluate the prognostic significance of baseline N-terminal pro–B-type natriuretic peptide (NT-proBNP), whether NT-proBNP modified the treatment response to sacubitril/valsartan, and the treatment effect of sacubitril/valsartan on NT-proBNP overall and in key subgroups. Background: Sacubitril/valsartan reduces NT-proBNP in heart failure (HF) with both reduced and preserved ejection fraction (EF), but did not significantly reduce total HF hospitalizations and cardiovascular death compared with valsartan in patients with HF with preserved EF (HFpEF). Methods: In the PARAGON-HF (Efficacy and Safety of LCZ696 Compared to Valsartan, on Morbidity and Mortality in Heart Failure Patients With Preserved Ejection Fraction) trial, 4,796 patients with HFpEF and elevated NT-proBNP were randomized to sacubitril/valsartan or valsartan. NT-proBNP was measured at screening in all patients and at 5 subsequent times in >2,700 patients: before, between, and after sequential valsartan and sacubitril/valsartan run-in periods, and 16 and 48 weeks post-randomization. Results: Median NT-proBNP was 911 pg/ml (interquartile range: 464 to 1,613 pg/ml) at screening. Screening NT-proBNP was strongly associated with the primary endpoint, total HF hospitalizations and cardiovascular death (rate ratio [RR]: 1.68 per log increase in NT-proBNP, 95% confidence interval [CI]: 1.53 to 1.85; p < 0.001). This relationship was stronger in patients with atrial fibrillation (adjusted RR: 2.33 [95% CI: 1.89 to 2.87] vs. 1.58 [95% CI: 1.42 to 1.75] in patients without atrial fibrillation; p interaction <0.001) and weaker in obese patients (adjusted RR: 1.50 [95% CI: 1.31 to 1.71] vs. 1.92 [95% CI: 1.70 to 2.17] in nonobese patients; p interaction <0.001). Screening NT-proBNP did not modify the treatment effect of sacubitril/valsartan compared with valsartan (p interaction = 0.96). Sacubitril/valsartan reduced NT-proBNP by 19% (95% CI: 14% to 23%; p < 0.001) compared with valsartan 16 weeks post-randomization, with similar reductions in men (20%) and women (18%), and in patients with left ventricular EF ≤57% (20%) and >57% (18%). Decreases in NT-proBNP predicted lower subsequent risk of the primary endpoint. Conclusions: Baseline NT-proBNP predicted HF events but did not modify the sacubitril/valsartan treatment effect in patients with HFpEF. Sacubitril/valsartan reduced NT-proBNP consistently in men and women, and in patients with lower or higher EF.

Efficacy and safety of sodium–glucose co‐transporter 2 inhibition according to left ventricular ejection fraction in DAPA‐HF

AIMS:The aim of this study was to examine whether left ventricular ejection fraction (LVEF) modified efficacy and safety of dapagliflozin 10 mg compared with placebo in the 4744 patients with LVEF ≤40% randomized in the Dapagliflozin And Prevention of Adverse-outcomes in Heart Failure trial (DAPA-HF). METHODS AND RESULTS:We examined whether LVEF, analysed categorically or continuously, modified the effect of dapagliflozin. The primary efficacy outcome was the composite of a worsening heart failure (HF) event (unplanned HF hospitalization/an urgent HF visit requiring intravenous therapy) or cardiovascular death. Mean LVEF was 31.1% and LVEF categories analysed were: <26% (n = 1143), 26-30% (n = 1018), 31-35% (n = 1187), and >35% (n = 1396). Each 5% decrease in LVEF was associated with a higher risk of the primary outcome [hazard ratio (HR) 1.18; 95% confidence interval (CI) 1.13-1.24]. The benefit of dapagliflozin was consistent across the spectrum of LVEF: the dapagliflozin vs. placebo HR was 0.75 (95% CI 0.59-0.95) for LVEF <26%, 0.75 (0.57-0.98) for LVEF 26-30%, 0.67 (0.51-0.89) for LVEF 31-35%, and 0.83 (0.63-1.09) for LVEF >35% (P for interaction = 0.762). Similarly, the effect of dapagliflozin on the components of the primary endpoint was not modified by baseline LVEF (P for interaction for cardiovascular death = 0.974, and for worsening HF = 0.161). Safety of dapagliflozin was also consistent across the range of LVEF and neither efficacy nor safety were modified by diabetes status. CONCLUSION:Left ventricular ejection fraction was a significant predictor of hospitalization and mortality in patients with HF with reduced ejection fraction but did not modify the beneficial effect of dapagliflozin, overall or separately, in patients with and without diabetes.

Global Differences in Heart Failure With Preserved Ejection Fraction The PARAGON-HF Trial

Background: Heart failure with preserved ejection fraction (HFpEF) is a global public health problem with important regional differences. We investigated these differences in the PARAGON-HF trial (Prospective Comparison of Angiotensin Receptor Neprilysin Inhibitor With Angiotensin Receptor Blocker Global Outcomes in HFpEF), the largest and most inclusive global HFpEF trial. Methods: We studied differences in clinical characteristics, outcomes, and treatment effects of sacubitril/valsartan in 4796 patients with HFpEF from the PARAGON-HF trial, grouped according to geographic region. Results: Regional differences in patient characteristics and comorbidities were observed: patients from Western Europe were oldest (mean 75 +/- 7 years) with the highest prevalence of atrial fibrillation/flutter (36%); Central/Eastern European patients were youngest (mean 71 +/- 8 years) with the highest prevalence of coronary artery disease (50%); North American patients had the highest prevalence of obesity (65%) and diabetes (49%); Latin American patients were younger (73 +/- 9 years) and had a high prevalence of obesity (53%); and Asia-Pacific patients had a high prevalence of diabetes (44%), despite a low prevalence of obesity (26%). Rates of the primary composite end point of total hospitalizations for HF and death from cardiovascular causes were lower in patients from Central Europe (9 per 100 patient-years) and highest in patients from North America (28 per 100 patient-years), which was primarily driven by a greater number of total hospitalizations for HF. The effect of treatment with sacubitril-valsartan was not modified by region (interaction P>0.05). Conclusions: Among patients with HFpEF recruited worldwide in PARAGON-HF, there were important regional differences in clinical characteristics and outcomes, which may have implications for the design of future clinical trials.

Dapagliflozin and Diuretic Use in Patients With Heart Failure and Reduced Ejection Fraction in DAPA-HF

Background: In the DAPA-HF trial (Dapagliflozin and Prevention of Adverse-Outcomes in Heart Failure), the sodium-glucose cotransporter 2 inhibitor dapagliflozin reduced the risk of worsening heart failure and death in patients with heart failure and reduced ejection fraction. We examined the efficacy and tolerability of dapagliflozin in relation to background diuretic treatment and change in diuretic therapy after randomization to dapagliflozin or placebo. Methods: We examined the effects of study treatment in the following subgroups: No diuretic and diuretic dose equivalent to furosemide 40 mg daily at baseline. We examined the primary composite end point of cardiovascular death or a worsening heart failure event and its components, all-cause death and symptoms. Results: Of 4616 analyzable patients, 736 (15.9%) were on no diuretic, 1311 (28.4%) were on 40 mg. Compared with placebo, dapagliflozin reduced the risk of the primary end point across each of these subgroups: Hazard ratios were 0.57 (95% CI, 0.36-0.92), 0.83 (95% CI, 0.63-1.10), 0.77 (95% CI, 0.60-0.99), and 0.78 (95% CI, 0.63-0.97), respectively (P for interaction=0.61). The hazard ratio in patients taking any diuretic was 0.78 (95% CI, 0.68-0.90). Improvements in symptoms and treatment toleration were consistent across the diuretic subgroups. Diuretic dose did not change in most patients during follow-up, and mean diuretic dose did not differ between the dapagliflozin and placebo groups after randomization. Conclusions: The efficacy and safety of dapagliflozin were consistent across the diuretic subgroups examined in DAPA-HF

Prescribing patterns of evidence-based heart failure pharmacotherapy and outcomes in the ASIAN-HF registry:a cohort study

Background Angiotensin-converting enzyme (ACE) inhibitors or angiotensin II receptor blockers (ARBs), beta blockers, and mineralocorticoid receptor antagonists (MRAs) are of proven benefit and are recommended by guidelines for management of patients with heart failure and reduced ejection fraction (HFrEF). We aimed to examine the first prospective multinational data from Asia on prescribing patterns of guideline-directed medical therapies and analyse its effect on outcomes. Methods In the prospective multinational ASIAN-HF registry (with enrolment from 46 centres in 11 countries in Asia), we enrolled patients aged 18 years or older, with symptomatic heart failure (stage C, with at least one episode of decompensated heart failure in the past 6 months that resulted in admission to hospital or was treated in an outpatient clinic) and left ventricular systolic dysfunction (ejection fraction Findings Between Oct 1, 2012, and Dec 31, 2015, we enrolled 5276 patients with HFrEF (mean age 59.6 years [SD 13.2], 77% men, body-mass index 24.9 kg/m(2) [5.1], 33% New York Heart Association class III or IV). Followup data were available for 4544 (90%) of 5061 eligible patients taking medication for heart failure, with median follow-up of 417 days (IQR 214-735). ACE inhibitors or ARBs were prescribed to 3868 (77%) of 5005 patients, beta blockers to 3975 (79%) of 5061, and MRAs to 2998 (58%) of 5205, with substantial regional variation. Guideline-recommended dose was achieved in only 17% of cases for ACE inhibitors or ARB, 13% for beta blockers, and 29% for MRAs. Country (all three drug classes), increasing body-mass index (ACE inhibitors or ARBs and MRAs), and in-patient recruitment (ACE inhibitors or ARBs and beta blockers) were associated with attainment of guideline-recommended dose (all p= 100%]). Interpretation Guideline-directed medical therapies at recommended doses are underutilised in patients with HFrEF. Improved uptake and uptitration of guideline-directed medical therapies are needed for better patient outcomes. Copyright (C) 2018 The Author(s). Published by Elsevier Ltd

Health status across major subgroups of patients with heart failure and preserved ejection fraction

AIMS: There are limited data on health status and changes in it over time across major subgroups of patients with heart failure and preserved ejection fraction (HFpEF), including ejection fraction spectrum, age, sex, region, body mass index (BMI), and comorbidities including diabetes, chronic kidney disease (CKD), anaemia, and atrial fibrillation/flutter. METHODS AND RESULTS: In the EMPEROR-Preserved trial, the Kansas City Cardiomyopathy Questionnaire (KCCQ) was assessed at baseline, 12, 32 and 52 weeks. Determinants of baseline KCCQ score and change over time, and the impact of empagliflozin on KCCQ scores were studied in specified subgroups. A Cox model was used to assess the association between 5- and 10-point increase and 5-point decrease in KCCQ score from baseline to week 12 and later outcomes. Among 2979 participants in the placebo arm, mean KCCQ clinical summary score (CSS) was 70.7 (20.8). Older age, female sex, BMI, anaemia, and a history of diabetes, and CKD were associated with worse scores. KCCQ-CSS score improved during follow-up; patients with atrial fibrillation/flutter at enrollment (p trend = 0.014) and CKD (p trend < 0.001) had less improvement. A 5-point increase in KCCQ-CSS at week 12 was associated with lower risk of cardiovascular death or heart failure hospitalization (5%), cardiovascular death (8%), and first heart failure hospitalization (4%) subsequently. A similar trend was seen with KCCQ total symptom score (TSS) and overall summary score (OSS). Empagliflozin improved KCCQ-CSS, -TSS and -OSS scores similarly across subgroups studied except for greater improvement in patients with the highest BMI (p trend = 0.153, 0.08 and 0.078, respectively). CONCLUSION: Health status in patients with HFpEF is impaired, especially in elderly, women, and those with obesity and comorbidities. Empagliflozin improved health status among all key subgroups studied with a greater effect in obese patients

Empagliflozin, Health Status, and Quality of Life in Patients With Heart Failure and Preserved Ejection Fraction: The EMPEROR-Preserved Trial

Background: Patients with heart failure with preserved ejection fraction have significant impairment in health-related quality of life. In the EMPEROR-Preserved trial (Empagliflozin Outcome Trial in Patients With Chronic Heart Failure With Preserved Ejection Fraction), we evaluated the efficacy of empagliflozin on health-related quality of life in patients with heart failure with preserved ejection fraction and whether the clinical benefit observed with empagliflozin varies according to baseline health status. Methods: Health-related quality of life was measured with the Kansas City Cardiomyopathy Questionnaire (KCCQ) at baseline and 12, 32, and 52 weeks. Patients were divided by baseline KCCQ Clinical Summary Score (CSS) tertiles, and the effect of empagliflozin on outcomes was examined. The effect of empagliflozin on KCCQ-CSS, Total Symptom Score, and Overall Summary Score was evaluated. Responder analyses were performed to compare the odds of improvement and deterioration in KCCQ related to treatment with empagliflozin. Results: The effect of empagliflozin on reducing the risk of time to cardiovascular death or heart failure hospitalization was consistent across baseline KCCQ-CSS tertiles (hazard ratio, 0.83 [95% CI, 0.69–1.00], 0.70 [95% CI, 0.55–0.88], and 0.82 [95% CI, 0.62–1.08] for scores <62.5, 62.5–83.3, and ≥83.3, respectively; P trend=0.77). Similar results were seen for total heart failure hospitalizations. Patients treated with empagliflozin had significant improvement in KCCQ-CSS versus placebo (+1.03, +1.24, and +1.50 at 12, 32, and 52 weeks, respectively; P<0.01); similar results were seen for Total Symptom Score and Overall Summary Score. At 12 weeks, patients on empagliflozin had higher odds of improvement ≥5 points (odds ratio, 1.23 [95% CI, 1.10–1.37]), ≥10 points (odds ratio, 1.15 [95% CI, 1.03–1.27]), and ≥15 points (odds ratio, 1.13 [95% CI, 1.02–1.26]) and lower odds of deterioration ≥5 points in KCCQ-CSS (odds ratio, 0.85 [95% CI, 0.75–0.97]). A similar pattern was seen at 32 and 52 weeks, and results were consistent for Total Symptom Score and Overall Summary Score. Conclusions: In patients with heart failure with preserved ejection fraction, empagliflozin reduced the risk for major heart failure outcomes across the range of baseline KCCQ scores. Empagliflozin improved health-related quality of life, an effect that appeared early and was sustained for at least 1 year
