BACKGROUND: Surgical exclusion of the left atrial appendage (LAA) can be performed at the time of cardiac operation as a potential modality to decrease cardioembolic risk attributable to atrial fibrillation (AF), but it remains unclear if this decreases stroke incidence. Furthermore, it is not known whether LAA exclusion impacts the decision to discontinue anticoagulation impacting subsequent stroke risk. HYPOTHESIS: LAA exclusion does not significantly alter subsequent anticoagulation use or stroke incidence...

BACKGROUND: Hypothyroidism has been known to be associated with hyperlipidemia, endothelial dysfunction and atherosclerosis. Elevation of thyroid-stimulation hormone (TSH) is a gold standard to detect these conditions. However, no large studies have investigated the association between TSH elevation and long-term clinical outcomes in patients with acute myocardial infarction (AMI). HYPOTHESIS: Hypothyroidism is associated with higher mortality in patients with AMI...

BACKGROUND: South Asians have a low prevalence of atrial fibrillation (AF) compared with Caucasians despite having a higher prevalence of conventional risk factors for the arrhythmia. The reason for this disparity is uncertain but may be due to ethnic differences in atrial morphology. This study examines the association between ethnicity and left atrial (LA) size and function in South Asian and Caucasian subjects using the reference technique of cardiovascular magnetic resonance imaging (MRI)...

Isolated cardiac sarcoidosis is a generally accepted disease condition, and the low yield of endomyocardial biopsy because of patchy involvement is also well known. However, current guidelines still require histologic confirmation of granuloma for the diagnosis of cardiac sarcoidosis, either in myocardial or extra-cardiac tissues. Therefore, only a presumptive diagnosis of chronic multifocal myocarditis of unknown origin can be made in a large number of patients in whom the only considerable diagnosis is cardiac sarcoidosis based on current knowledge...

BACKGROUND: Cardiac resynchronization therapy (CRT) is highly beneficial in patients with heart failure and left bundle branch block, however up to 30% of patients in this selected group are non-responders. HYPOTHESIS: We hypothesized that clinical and echocardiographic variables can be used to develop a simple mortality risk stratification score in CRT. METHODS: Best-subsets proportional-hazards regression analysis was used to develop a simple clinical risk score for all-cause mortality in 756 patients with left bundle branch block (LBBB) allocated to the CRT with defibrillator (CRT-D) group enrolled in the Multicenter Automatic Defibrillator Implantation Trial with Cardiac Resynchronization Therapy (MADIT-CRT)...

BACKGROUND: Small studies have shown that adenosine is equivalent to regadenoson when obtaining coronary fractional flow reserve (FFR) measurements. A study that also evaluates time and safety of aminophylline reversal of regadenoson effects has not been presented. HYPOTHESIS: Reversal of regadenoson with aminophylline is safe and equivalent to adenosine for FFR measurements. METHODS: Forty-six consecutive patients who underwent clinically indicated FFRs at the time of coronary angiography were enrolled between 4/2012 and 5/2014...

Heart failure (HF) and type 2 diabetes mellitus (T2DM) are two global pandemics, affecting over 25 million and 420 million people, respectively. The prevalence of comorbid HF and T2DM is rising, and the prognosis remains poor. One central area of overlap of these two disease processes is renal dysfunction, which contributes to poor cardiovascular outcomes and mortality. As such, there is a growing need for antihyperglycemic agents with cardio- renoprotective effects. Three classes of novel antihyperglycemic agents, sodium-glucose cotransporter-2 (SGLT2) inhibitors, glucagon-like peptide-1 receptor agonists (GLP-1RA), and dipeptidyl peptidase-4 (DPP4) inhibitors have demonstrated varied cardiorenal outcomes in recent cardiovascular outcomes trials...

BACKGROUND: It is uncertain whether omega-3 fatty acids are beneficial in statin-treated patients. Epanova is a mix of omega-3 free fatty acids, not requiring co-ingestion with food, which can lower triglycerides by up to 31%. STRENGTH will examine whether Epanova 4 g daily reduces the rate of cardiovascular events in statin-treated patients with hypertriglyceridemia and low levels of HDL-C at high risk for developing cardiovascular events. STUDY DESIGN: STRENGTH is a randomized, double-blind, placebo-controlled trial...

BACKGROUND: Atrial fibrillation occurring transiently with stress (AFOTS) describes the first detection of AF in a patient who is hospitalized for a non-cardiac medical illness or following non-cardiac surgery. Uncertainty exists whether episodes of AFOTS are due to reversible precipitants and will not recur after recovery, or if they are paroxysmal AF that is detected during inpatient cardiac monitoring. Previous studies have used retrospective, non-systematic and ultimately low-sensitivity protocols to investigate the recurrence of AF in patients with AFOTS...

BACKGROUND: Evolocumab significantly lowers low-density lipoprotein cholesterol (LDL-C) when dosed 140 mg every 2 weeks (Q2W) or 420 mg monthly (QM) subcutaneously. HYPOTHESIS: LDL-C changes are comparable among different patient subgroups in a pooled analysis of data from phase 3 trials. METHODS: A total of 3146 patients received ≥1 dose of evolocumab or control in four 12-week phase 3 studies. Percent change from baseline in LDL-C for evolocumab 140 mg Q2W or 420 mg QM vs control was reported as the average of week 10 and 12 values...
