Healthy Behavior, Risk Factor Control, and Survival in the COURAGE Trial
Original Research | By DJ Maron, GBJ Mancini, COURAGE Trial Group et al.
BACKGROUND - Individual risk factor control improves survival in patients with stable ischemic heart disease (SIHD). It is uncertain if multiple risk factor control further extends survival. OBJECTIVES - This study determined whether a greater number of risk factors at goal predicted improved survival in SIHD patients. METHODS - Of 2,287 participants in the COURAGE (C...
Original Research | By Adjedj J, Picard F, Mogi S et al.
OBJECTIVES - To evaluate, in vitro, SB stenting techniques after failed provisional stenting. We aimed to compare flows and stent strut apposition of T and protrusion (TAP) versus Reversed String (RS) techniques using a flow simulator, optical coherence tomography (OCT) using silicon bifurcation phantoms with different bifurcation angulations. BACKGROUND - While bifurcation coronary artery steno...
Original Research | By Montefusco A, D'Ascenzo F, Gili S et al.
OBJECTIVES - To compare the effectiveness and safety of self-expandable, sirolimus-eluting Stentys stents (SES) and second-generation drug-eluting stents (DES-II) for the treatment of the unprotected left main (ULM). BACKGROUND - SES may provide a valuable option to treat distal ULM, particularly when significant caliber gaps with side branches are observed. METHODS - Patients from t...
Cardiorespiratory Fitness and Mortality in Healthy Men and Women
Original Research | By MT Imboden, MP Harber, MH Whaley et al.
BACKGROUND - There is a well-established inverse relationship between cardiorespiratory fitness (CRF) and mortality. However, this relationship has almost exclusively been studied using estimated CRF. OBJECTIVES - This study aimed to assess the association of directly measured CRF, obtained using cardiopulmonary exercise (CPX) testing with all-cause, cardiovascular disease (CVD), and cancer mortal...
Lifestyle Modifications for Preventing and Treating Heart Failure
Clinical Trial | By Abraham WT, Kuck KH, FIX-HF-5 Investigators and Coordinators.
OBJECTIVES - This study sought to confirm a subgroup analysis of the prior FIX-HF-5 (Evaluate Safety and Efficacy of the OPTIMIZER System in Subjects With Moderate-to-Severe Heart Failure) study showing that cardiac contractility modulation (CCM) improved exercise tolerance (ET) and quality of life in patients with ejection fractions between 25% and 45%. BACKGROUN...
Clinical Trial | By Abraham WT, Burkhoff D, FIX-HF-5 Investigators and Coordinators.
Cardiac contractility modulation (CCM) signals are nonexcitatory electrical signals delivered during the cardiac absolute refractory period that enhance the strength of cardiac muscular contraction. Prior research in experimental and human heart failure has shown that CCM signals normalize phosphorylation of key proteins and expression of genes coding for proteins involved in regulation of calcium cycling and contraction. The results of prior c...
sST2 Predicts Outcome in Chronic Heart Failure Beyond NT−proBNP and High-Sensitivity Troponin T
Original Research | By M Emdin, A Aimo, G Vergaro et al.
BACKGROUND - Soluble suppression of tumorigenesis-2 (sST2) is a biomarker related to inflammation and fibrosis. OBJECTIVES - This study assessed the independent prognostic value of sST2 in chronic heart failure (HF). METHODS - Individual patient data from studies that assessed sST2 for risk prediction in chronic HF, together with N-terminal pro−B-type natriure...
