Observational Study
Etiology of Heart Failure and Outcomes in Patients Hospitalized for Acute Decompensated Heart Failure With Preserved or Reduced Ejection Fraction.
In the setting of acute decompensated heart failure (HF), relations among the etiology of HF, left ventricular systolic function, and outcomes are unclear. The aim of this study was to investigate the association of HF etiology with outcomes in patients with acute decompensated HF with a preserved or reduced ejection fraction (EF). Of the 4,842 patients enrolled in the Acute Decompensated Heart Failure Syndromes registry, 3,810 patients (1,601 with a preserved EF and 2,209 with a reduced EF) who had a hypertensive, ischemic, valvular, or idiopathic dilated etiology of HF were investigated to assess the association of etiology with a composite end point (all-cause mortality and readmission for HF). ⋯ After adjustment for multiple co-morbidities, the risk of the composite end point was comparable among hypertensive, ischemic, and valvular etiologies in the preserved EF group. In contrast, in the reduced EF group, ischemic etiology was associated with a tendency toward greater risk of the composite end point than hypertensive etiology (but this difference was not significant), whereas valvular etiology was associated with a significantly greater risk of the composite end point relative to hypertensive or idiopathic dilated etiology. In conclusion, this study demonstrated that taking the etiology of HF into account may help to reduce the heterogeneity of acute decompensated HF and assist in identifying patients at risk of adverse outcomes, especially among patients with reduced EF.

Transcatheter aortic valve replacement (TAVR) with percutaneous coronary intervention (PCI) has emerged as a less-invasive therapeutic option for high surgical risk patients with aortic stenosis and coronary artery disease. The aim of this study was to determine the outcomes of TAVR when performed with PCI during the same hospitalization. We identified patients using the International Classification of Diseases, Ninth Revision, Clinical Modification procedure codes from the Nationwide Inpatient Sample between the years 2011 and 2013. ⋯ The propensity score-matched analysis yielded similar results. In conclusion, performing PCI along with TAVR during the same hospital admission is associated with higher mortality, complications, and cost compared with TAVR alone. Patients would perhaps be better served by staged PCI before TAVR.

Transcatheter aortic valve replacement (TAVR) is conventionally performed under general anesthesia (GA) allowing intraoperative transoesophageal echocardiogram imaging. We present our experience in patients having the procedure under local anesthesia (LA), who were subsequently transferred to a low dependency unit postprocedure, to assess safety and length of hospital stay. We retrospectively assessed all the transfemoral TAVR procedures conducted at our center from January 03, 2011. ⋯ In conclusion, performing a TAVR under LA is at least as safe as GA. In addition, there is a reduced procedural time and length of hospital stay. LA is a safe and cost-effective alternative to GA and patients can be safely transferred to a low dependency unit.

Factors Associated With Resource Utilization and Coronary Artery Dilation in Refractory Kawasaki Disease (from the Pediatric Health Information System Database).
Management guidelines for refractory Kawasaki disease (KD) are vague. We sought to assess practice variation and identify factors associated with large/complex coronary artery aneurysms (LCAA) and resource utilization in refractory KD. This retrospective cohort study identified patients aged ≤18 years with KD (2004 to 2014) using the Pediatric Health Information System. ⋯ In conclusion, treatment for refractory KD varies widely. Concomitant viral infection was associated with a greater risk of LCAA in refractory KD. Better understanding of optimal management may improve outcomes and decrease both variability in management and resource utilization for refractory KD.

Decision-making in acute chest pain remains challenging despite normal (below ninety-ninth percentile) high-sensitivity troponin (hs-cTn). Some studies suggest that undetectable hs-cTn, far below the ninety-ninth percentile, might rule out acute coronary syndrome. We investigated clinical data in comparison to undetectable hs-cTnT. ⋯ Likewise, the negative predictive values of score = 0 (97.5%, 100%) and ≤1 point (95.9%, 100%) were higher than using undetectable hs-cTnT (91.9%, 98.1%). Both clinical scores of 0 and ≤1 better classified patients at risk of MACE (p = 0.0001, log-rank test) than hs-cTnT <5 ng/l (p = 0.06). In conclusion, clinical data can guide decision-making and perform at least equally well as undetectable hs-cTnT, in patients presenting at the emergency department with chest pain and normal hs-cTnT.
