Hypertrophic cardiomyopathy (HC) is a disease that mainly affects the left ventricle (LV), however recent studies have suggested that it can also be associated with right ventricular (RV) dysfunction. The…
Although P-wave axis is routinely reported on the printouts of most contemporary electrocardiograms, the prognostic significance of its abnormality has not been systematically evaluated. We examined the association between abnormal…
Dual antiplatelet therapy is commonly used in patients undergoing transcatheter aortic valve implantation (TAVI), but the optimal antiplatelet regimen is uncertain and remains to be determined. The objective of this…
Noonan syndrome (NS) is a genetic disorder caused by mutations altering proteins relevant to RAS/mitogen-activated protein kinase signal transduction. Cardiac involvement is common, most prevalently pulmonary valve stenosis and hypertrophic…
In patients with aortic stenosis who cannot have surgery, transcatheter aortic valve replacement using the Edwards SAPIEN valve has been shown to improve survival rate and is approved for commercial…
Patients with implantable cardioverter defibrillators (ICDs) can require antiarrhythmic drugs to manage arrhythmias and prevent device shocks. We sought to determine the prevalence, clinical correlates, and institutional variation in the…
Adiponectin exhibits cardioprotective properties in experimental studies, but elevated levels have been linked to increased mortality in older adults and patients with chronic heart failure (HF). The adipokine’s association with…
Heart failure with preserved ejection fraction (HFpEF) is a clinical syndrome of exercise intolerance due to impaired myocardial relaxation and/or increased stiffness. Patients with HFpEF often show signs of chronic…
It is unknown whether echocardiographic morphologic and hemodynamic parameters have incremental value in predicting 30-day heart failure (HF)-specific readmission risk among patients admitted with HF. We performed a prospective cohort…
Apolipoprotein E, a protein component of blood lipid particles, plays an important role in lipid transport. Different mutations in the apolipoprotein E gene have been associated with various clinical phenotypes….
