BACKGROUND: The benefit of aspirin among patients with stable atherosclerosis without a prior ischemic event is not well defined. HYPOTHESIS: Aspirin would be of benefit in outpatients with atherosclerosis with prior ischemic events, but not in those without ischemic events. METHODS: Subjects from the Reduction of Atherothrombosis for Continued Health registry were divided according to prior ischemic event (n =21 724) vs stable atherosclerosis, but no prior ischemic event (n = 11 872)...

BACKGROUND: Heart rate has been associated with prognosis in patients with heart failure with reduced ejection fraction (HFREF) and sinus rhythm; whether this also holds true in patients with atrial fibrillation (AF) is unknown. HYPOTHESIS: To evaluate cardiac rhythm and baseline heart rate and the influence of outcome in patients with HFREF enrolled in the Cardiac Insufficiency Bisoprolol Study II. METHODS: In total, 2539 patients were stratified according to their baseline heart rhythm (AF or sinus rhythm) and into quartiles of heart rate (≤70 bpm, 71-78 bpm, 79-90 bpm, and >90 bpm)...

BACKGROUND: Diabetes mellitus (DM) is associated with adverse outcomes after surgical aortic valve replacement. However, there are conflicting data on the impact of DM on outcomes of transcatheter aortic valve replacement (TAVR). HYPOTHESIS: DM is associated with poor outcomes after different cardiac procedures. Therefore, DM can also be associated with poor outcomes after TAVR. METHODS: We searched PubMed and Cochrane Central Register of Controlled Trials for studies that evaluated outcomes after TAVR and stratified at least 1 of the studied endpoints by DM status...

Heart failure with preserved ejection fraction (HFpEF) now accounts for the majority of confirmed HF cases in the United States. However, there are no highly effective evidence-based treatments currently available for these patients. Inflammation correlates positively with adverse outcomes in HF patients. Interleukin (IL)-1, a prototypical inflammatory cytokine, has been implicated as a driver of diastolic dysfunction in preclinical animal models and a pilot clinical trial. The Diastolic Heart Failure Anakinra Response Trial 2 (D-HART2) is a phase 2, 2:1 randomized, double-blind, placebo-controlled clinical trial that will test the hypothesis that IL-1 blockade with anakinra (recombinant human IL-1 receptor antagonist) improves (1) cardiorespiratory fitness, (2) objective evidence of diastolic dysfunction, and (3) elevated inflammation in patients with HFpEF (http://www...

BACKGROUND: To evaluate subtle and early premature ventricular complex (PVC)-induced ventricular impairment in patients with frequent PVCs and without structural heart disease by real-time 3-dimensional (3D) speckle tracking echocardiography (RT3D-STE). HYPOTHESIS: Patients with frequent premature ventricular complexes with normal left ventricular ejection fraction have subtle left ventricular dysfunction. METHODS: Forty patients (22 male) with a single source of frequent PVCs and 40 healthy controls (24 male) underwent assessment by conventional 2-dimensional (2D) echocardiography and RT3D-STE...

Hospitals typically use Center for Medicare and Medicaid Services' (CMS) Hospital Readmission Reduction Program (HRRP) administrative reports as the standard of heart failure (HF) admission quantification. We aimed to evaluate the HF admission population identified by CMS HRRP definition of HF hospital admissions compared with a clinically based HF definition. We evaluated all hospital admissions at an academic medical center over 16 months in patients with Medicare fee-for service benefits and age ≥65 years...

REVIEW
Alessio Lilli, Andrea Di Cori, Valerio Zacà
Oral anticoagulation (OAC) is recommended in both paroxysmal atrial fibrillation (pxAF) and nonparoxysmal AF (non-pxAF), but disagreement exists in classes of recommendation. Data on incidence/rate of stroke in pxAF are conflicting, and OAC is often underused in this population. The objectives of the meta-analysis were to investigate different impact on outcomes of pxAF and non-pxAF, with and without OAC. Two reviewers searched for prospective studies on risk of stroke and systemic embolism (SE) in pxAF and non-pxAF, with and without OAC...

BACKGROUND: We investigated the modifying role and prognostic importance of diastolic dysfunction (DD) in patients with heart failure and systolic dysfunction (SD). HYPOTHESIS: The echocardiographic evaluation of diastolic function in patients with SD provides further prognostic information. METHODS: From the German Competence Network Heart Failure, 1046 heart failure patients with reduced left ventricular ejection fraction (LVEF; <50%) were echocardiographically studied and followed for a median of 5 years...

BACKGROUND: Apnea diving has gained worldwide popularity, even though the pathophysiological consequences of this challenging sport on the human body are poorly investigated and understood. This study aims to assess the influence of sustained apnea in healthy volunteers on circulating microparticles (MPs) and microRNAs (miRs), which are established biomarkers reflecting vascular function. HYPOTHESIS: Short intermittent hypoxia due to voluntary breath-holding affects circulating levels of endothelial cell-derived MPs (EMPs) and endothelial cell-derived miRs...

BACKGROUND: Epicardial adipose tissue is associated with coronary artery disease (CAD). Circulating endothelial progenitor cell (EPC) level represents a marker of endothelial dysfunction and vascular health. However, the relationship between epicardial fat and circulating EPC remains unknown. This study aimed to investigate association between echocardiographic epicardial fat thickness (EFT) and circulating EPC level. HYPOTHESIS: Epicardial fat causes inflammation and contributes to progression of CAD...

Breast arterial calcification (BAC) is a type of medial artery calcification that can be seen incidentally on mammography. Studies have suggested association of BAC with cardiovascular risk factors, coronary artery disease (CAD), and cardiovascular morbidity and mortality. Recently published studies have also suggested a modest correlation of BAC with coronary artery calcium (CAC) scoring. Roughly 40 million mammograms are already performed annually in the United States with overlap in patients that undergo CAD screening via CAC scoring...

BACKGROUND: There is no consistent evidence to suggest the association of plasma lipoprotein(a) (Lp[a]) with long-term mortality in patients undergoing coronary angiography (CAG) or percutaneous coronary intervention (PCI). HYPOTHESIS: Level of Lp(a) is associated with long-term mortality following CAG or PCI. METHODS: We enrolled 1684 patients with plasma Lp(a) data undergoing CAG or PCI between April 2009 and December 2013. The patients were divided into 2 groups: a low-Lp(a) group (Lp[a] <16...

BACKGROUND: Mitogen-activated protein kinase-1 (MAPK1), as well as its downstream factors of hypoxia-inducible factor-1 (HIF-1) and heme oxygenase-1 (HO-1), have been documented to be involved in modulating development of coronary artery disease (CAD). HYPOTHESIS: Genetic mutations within the MAPK1/HIF-1/HO-1 signaling pathway could alter the risk of perimenopausal CAD in Chinese patients. METHODS: Peripheral blood samples were gathered from 589 CAD patients and 860 healthy controls, and 12 potential single-nucleotide polymorphisms (SNPs) were obtained from HapMap database and previously published studies...

BACKGROUND: Both stress cardiomyopathy (SCMP) and acute myocardial infarction (AMI) present with similar clinical symptoms and signs, and apical akinesis. HYPOTHESIS: Quantitative segmental analysis of myocardial contrast echocardiography (MCE) helps to differentiate AMI from SCMP. METHODS: Real-time MCE was performed in 33 consecutive patients who presented with an acute symptom/sign and a new apical akinesis on echocardiography. In 18 left ventricular (LV) myocardial segments, a replenishment curve was obtained in each segment to measure peak plateau myocardial contrast intensity (MCI) (A) and the replenishment curve slope (β)...

BACKGROUND: The acute effects of statin loading dose (LD) on platelet reactivity in patients with chronic stable angina (CSA) are not completely clear. HYPOTHESIS: We hypothesized that LDs of atorvastatin and rosuvastatin have different pharmacodynamic acute effects on platelet aggregability in CSA patients with baseline normal platelet reactivity while on dual antiplatelet therapy (DAPT). METHODS: From September 2011 to February 2014, all consecutive CSA patients on chronic DAPT (aspirin and clopidogrel) were evaluated before elective percutaneous coronary intervention (PCI)...

BACKGROUND: The interventional left atrial appendage (LAA) closure represents an emerging alternative to oral anticoagulation for stroke prevention in certain atrial fibrillation patients. Preliminary results have suggested high procedural success rates and fewer peri-interventional complications; however, there persists an insufficient understanding of the role of many underlying confounding variables (e.g., anatomical characteristics). HYPOTHESIS: It was investigated whether varying LAA morphologies influence procedural success as well as in-hospital outcome...

Randomized clinical trials that examined long-term clinical outcomes of routine aspiration thrombectomy prior to primary percutaneous coronary intervention (PCI) in patients with acute ST-segment elevation myocardial infarction have yielded different results. We hypothesized that the routine use of manual thrombus aspiration prior to primary PCI lacks long-term clinical benefits. Electronic databases were searched for randomized trials comparing routine aspiration thrombectomy and conventional PCI. We included only trials that reported clinical outcomes beyond 6 months...
