Influenza virus infection is associated with significant morbidity and mortality in patients with chronic diseases including heart failure (HF). Annual influenza vaccination is recommended to prevent infection during the winter […]

Transthyretin cardiac amyloidosis (ATTR-CA) is an increasingly recognized infiltrative cardiomyopathy in which conduction system disease is common. The aim of our study was to define the incidence and prevalence of […]

Involvement of atherosclerosis in extracardiac vascular territories may identify coronary artery disease (CAD) patients at higher risk for adverse events. We investigated the long-term prognostic implications of polyvascular disease in […]

Valvular atrial fibrillation (AF) is defined as AF in the presence of mitral stenosis or mechanical valve prosthesis. However, there are patients with AF who have significant native valvular heart […]

Left atrial calcium (LAC) is often observed in patients who have undergone mitral valve (MV) surgery, but little is known about its characteristics and clinical implications. Therefore, we sought to […]

We obtained directly measured maximal oxygen uptake (VO2 max) by open-circuit spirometry in 1,453 patients with chronic heart failure (HF) who completed a treadmill test (n = 1,453) or cycle ergometry (n = 1,838), […]

Left ventricular assist devices (LVADs) use in treatment of stage D heart failure (HF) has evolved and expanded in the past decade. There is paucity of data on LVAD utilization […]

We sought to study the feasibility of axillary artery as alternative access for mechanical circulatory support (MCS) in cardiogenic shock and high-risk percutaneous coronary intervention (HR-PCI) patients with severe occlusive […]

Normal-flow low-gradient severe aortic stenosis (NF-LG-SAS), defined by an aortic valve area (AVA) <1 cm², mean pressure gradient (MPG) <40 mm Hg and indexed stroke volume ≥35 ml/m², is the […]

Women and patients with incomplete revascularization (IR) have a worse prognosis after ST elevation myocardial infarction (STEMI). However, the extent to which IR affects outcomes for women with STEMI compared […]

Patients with elevated but stable levels of high-sensitivity cardiac troponin (hs-cTn) have a high risk of premature death and cardiovascular events. This study aimed to investigate the association between stable […]

Patients with preserved left ventricular (LV) ejection function (EF) and atrioventricular block (AVB) who are anticipated for high-burden of right ventricular (RV) pacing possess a risk to develop pacing-induced cardiomyopathy […]

Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are novel drugs that provide striking lowering of low-density lipoprotein cholesterol (LDL-C) when added to maximum tolerated therapy in patients with hypercholesterolemia. Ceramides, […]

Recently, the Heart Rhythm Society published recommendations on management of patients with cardiac implantable electronic device (CIED) who require radiotherapy (RT). We aimed to report the experience of a teaching […]

The association between objectively measured physical activity and atrial fibrillation (AF) has not been examined. Therefore, we examined the association between moderate and vigorous physical activity (MVPA) with incident AF […]

Abnormal P-wave axis may reflect preclinical atrial dysfunction and has been associated with an increased risk of incident atrial fibrillation (AF) in the general population. Patients with diabetes mellitus (DM) […]

The Center for Medicare & Medicaid Services has identified readmission as an important quality metric in assessing hospital performance and value of care. The aim of this study was to […]

Although atrial fibrillation (AF) is strongly associated with stroke, previous studies have shown suboptimal use of anticoagulation (AC). In particular, there is a lack of data on the long-term use […]

The immune response after transcatheter aortic valve implantation (TAVI) in comparison to that after surgical aortic valve replacement (SAVR) remains to be fully elucidated. In a 2-part study, we assessed […]

Early-onset cardiomyopathy is a major concern for people with type 1 diabetes mellitus (DM). Studies examining myocardial deformation indices early in the disease process in people with have provided conflicting […]

The Marfan syndrome (MFS) patients are highly predisposed to thoracic aortic aneurysm and/or dissection, with virtually every patient having evidence of aortic disease at some point during their lifetime. We […]

Endovascular interventions are commonly utilized for treatment of femoropopliteal peripheral artery disease. The relative efficacy of these interventions remains unclear. A Bayesian network meta-analysis was performed comparing 5 endovascular treatment […]

The prognosis of patients with left ventricular hypertrabeculation/noncompaction (LVHT) is assessed controversially. LVHT is associated with other cardiac abnormalities and with neuromuscular disorders (NMD). Aim of the study was to […]

Highly reliable identification of adults with hypertrophic cardiomyopathy (HC) at risk for sudden death (SD) has been reported. A significant controversy remains, however, regarding the most reliable risk stratification methodology […]

This study sought to investigate the impact of elective, uncomplicated target lesion revascularization (TLR) on long-term cardiac mortality after percutaneous coronary intervention (PCI) of unprotected left main coronary artery (ULMCA) […]

In this nation-wide cohort study we report the first long-term results of the association between having a atrial septal defects (ASD) on psychiatric disorders and use of psychotropic agents. Through […]

To conduct a systematic review and meta-analysis evaluating the safety and effectiveness of inferior vena cava filter (IVCF) placement in the setting of massive and submassive pulmonary embolism (PE), Pubmed […]

Influenza is associated with significant morbidity in the United States but its influence on in-hospital outcomes in patients with AMI has not been well studied. The Nationwide Readmission Database (NRD) […]

A mitral L-wave indicates advanced diastolic dysfunction with elevated left ventricular filling pressure. Previous studies have reported that the presence of a mitral L-wave is associated with a poor prognosis […]
