BACKGROUND: No data exist on comparisons of efficacy, safety and recurrence risk factors of paroxysmal and persistent atrial fibrillation (AF) ablation using robotic magnetic navigation system (MNS) respectively. METHODS: 151 AF patients were prospectively enrolled and divided into paroxysmal AF group (n=102) and persistent AF group (n=49). Circumferential pulmonary vein antrum isolation (CPVI) were performed in all patients. Linear ablation at the left atrial roof and mitral isthmus was performed in patients with persistent AF in addition to CPVI...

OBJECTIVES: As the debate continues about whether obesity in metabolically healthy individuals is associated with poor outcomes or not, investigating the association between the obesity phenotypes and markers of subclinical myocardial injury will help identify those at risk for future cardiovascular events (CVD). METHODS: This analysis included 3423 participants (57.85±13.06 years, 53.3% women) without known CVD from NHANES-III. Multivariable logistic regression models were used to examine the cross-sectional association between four obesity phenotypes (metabolically healthy non-obese (MHNO) (reference), metabolically unhealthy non-obese (MUNO), metabolically healthy obese (MHO) and metabolically unhealthy obese (MUO) with subclinical myocardial injury (SC-MI)...

We read with interest the study by Johnsrud et al. The authors retrospectively examined outcomes in a cohort of patients with atrial fibrillation undergoing surgical left atrial appendage (LAA) exclusion during cardiac surgery. The authors aimed to evaluate the long-term effect of LAA exclusion on oral anticoagulation (OAC) prescription and stroke. They evaluated 91 patients who, during surgery, underwent LAA exclusion and matched them to patients who did not. The final analysis included only 62 pairs, matched on 16 pre-treatment variables, and demonstrated no significant difference in OAC prescription and stroke at discharge and at 5 years...

Patients with type 2 diabetes have a significantly increased risk for cardiovascular disease (CVD) compared to the general population - with CVD accounting for two out of every three deaths in patients with diabetes. In 2008, the FDA suggested that CVD risk should be evaluated for any new antidiabetic therapy, leading to a multitude of large CVD outcome trials to assess CVD risk from these medications. However, several of these outcome trials with new novel anti-diabetic therapies have demonstrated a clear and definite CVD advantage at mid-term follow up in high risk patients with T2DM...

Pulmonary vascular resistance (PVR) and pulmonary vascular resistance index (PVRI) are key variables in a broad range of contexts, including prediction of outcomes in heart and liver transplantation, determining candidacy for closure of atrial or ventricular septal defects, and guiding treatment of pulmonary hypertension. Significant variability exists among the units used to report PVRI in current literature, making the interpretation of data and translation into clinical practice difficult. Here we will review the measurement and derivation of PVR and PVRI and demonstrate the extent of confusion in the literature...

BACKGROUND: A fragmented QRS complex (fQRS) is caused by conduction abnormalities of the ventricle secondary to myocardial ischemia and/or scar in patients with myocardial infarction. However, the implications of the fQRS in the development of coronary artery disease with myocardial ischemia in those without a scar remain unknown. METHODS: We studied electrocardiograms (ECGs) obtained from 150 patients (60.5±8.5 years, 102 men) with myocardial ischemia, which was confirmed by performing both, a nuclear exercise stress test and coronary angiography...

BACKGROUND: The effects of carvedilol and metoprolol succinate on appropriate and inappropriate implantable cardioverter defibrillator (ICD) therapy in patients with heart failure with reduced ejection fraction (HFrEF) are not fully understood. METHODS: All patients with ICD registered to a single device clinic between 1/2012 and 6/2017 (n = 569) were identified. Patients with systolic heart failure (left ventricular ejection fraction < 40%) treated with carvedilol vs metoprolol succinate were compared...

BACKGROUND: Standard measures of kidney function are only modestly useful for accurate prediction of risk for acute kidney injury (AKI). HYPOTHESIS: Clinical and biomarker data can predict AKI more accurately. METHODS: Using Luminex xMAP technology, we measured 109 biomarkers in blood from 889 patients prior to undergoing coronary angiography. Procedural AKI was defined as an absolute increase in serum creatinine of ≥0.3 mg/dL, a percentage increase in serum creatinine of ≥50%, or a reduction in urine output (documented oliguria of <0...

BACKGROUND: Hypertension remains poorly controlled on the population level. National rates of control, even when defined leniently by BP<140/90 mmHg, are only ~50%. As growing healthcare costs coincide with tighter blood pressure (BP) targets, innovative management programs are needed to maximize efficiency of care delivery and optimize control. HYPOTHESIS: We aimed to develop, a remote, navigator-led hypertension innovation program that would leverage algorithmic care pathways, home BP measurements and patient coaching to allow rapid and complete medication titration...

BACKGROUND: In non-valvular atrial fibrillation (NVAF) patients, congestive heart failure (CHF) confers an increased risk of stroke or systemic thromboembolism. This risk is present in both heart failure with reduced ejection fraction (HFrEF) and heart failure with preserved ejection fraction (HFpEF). It is unclear if clinicians account for both types of CHF in their NVAF anticoagulation practices. Accordingly, we characterized current outpatient anticoagulation trends in NVAF patients with HFpEF compared to patients with HFrEF...

BACKGROUND: Real-world data on the clinical outcomes of heart failure (HF) across the spectrum of ejection fraction (EF) and the prognostic value of B-type natriuretic peptide (BNP) have not been well examined. HYPOTHESIS: The real-world association between the clinical outcomes of HF and EF or BNP levels may differ across different EF or BNP values. METHODS: The Optum Integrated Claims-Clinical data (07/2009-09/2016) was used to identify adult patients with ≥1 HF diagnosis during a hospitalization or emergency room visit...

Atrial fibrillation (AF) is the most prevalent sustained cardiac arrhythmia in adults. Catheter ablation (CA) is one of the most important management strategies to reduce AF burden and AF-associated complications. In order to stratify the risk of adverse events and to predict treatment success in AF patients undergoing CA, several risk stratification scores had been developed during the last decade. The aim of this review is to provide an overview of the most important clinical risk scores predicting rhythm outcomes, electro-anatomical substrate and mortality in AF...

Thrombo-embolism is one of the serious complications of takotsubo syndrome (TS) in addition to heart failure, pulmonary edema, cardiogenic shock, cardiac arrest, life-threatening arrhythmias, left ventricular outlet tract obstruction, mitral regurgitation, cardiac rupture, and death. The most common cardio-embolic events in TS are cerebral, renal and peripheral embolism. Approximately one third of patients with left ventricular thrombus (LVT) in TS develop embolic complications. Cardio-embolism in TS may occur with or without the presence of detectable LVT...

BACKGROUND: We aimed to assess longitudinal changes of B-type natriuretic peptide (BNP) in AS patients treated by transcatheter aortic valve replacement (TAVR). METHODS: From our TAVR database, we identified 193 consecutive patients with severe symptomatic AS who underwent TAVR and were prospectively followed using serial BNP levels and echocardiography. Patients were divided in subgroups according to type of left ventricular (LV) remodeling as having normal LV mass and relative wall thickness, or showing concentric remodeling (CR), concentric hypertrophy (CH), and eccentric hypertrophy (EH)...
