Cardiovascular

Purpose: This article provides a brief overview of the diagnostic criteria and genomic risk factors for the components of metabolic syndrome (MetS).

Organizing Constructs: Contributions of cardiovascular, obesity, and diabetes genomic risk factors to the development of MetS as reported in the literature have been reviewed.

Abstract
BACKGROUND: Atrial and ventriclar tachyarrhythmias, as well as bradyarrhythmias, in the elderly with heart failure (HF) and/or hypertension (HTN) have been well documented. However, the frequency of these arrhythmias, whether silent or symptomatic, and their association with subsequent cardiac events has not been well defined in patients 65 years or older with HF and other cardiovascular risk factors.
OBJECTIVE: To assess the value of 2 weeks of remote, transtelephonic cardiac monitoring for detecting arrhythmias in an elderly, urban population living with HF.

ARRHYTHMOGENIC RIGHT VENTRICULAR cardiomyopathy (ARVC) is a dangerous cardiac condition that can cause sudden death. Characterized by a severely thinned and dilated right ventricle, ARVC results in abnormal contractions and blood ejection, as the ventricle walls are replaced by fibro-fatty tissue. In an athlete whose ventricle reaches maximal exertion, ARVC can cause sudden death. Accurate and early diagnosis of ARVC is crucial to prevent death.
 

 In 2009, President Obama signed an Executive Order calling for strategies to improve the health of Asian Americans and to seek data on the health disparities in Asian American subgroups.1 Data on Asian American subgroups are scarce and many health disparities remain unknown. The purpose of this Advisory is to highlight the gaps in existing research on cardiovascular disease (CVD) among Asian Americans, and to serve as a call to action on behalf of the American Heart Association to address these areas of need.

 Background: Patients who have undergone percutaneous catheter ablation for atrial fibrillation (AF) may develop cavotricuspid isthmus (CTI)-dependent atrial flutter (AFL), which can occur either spontaneously during left atrial (LA) ablation for AF or by induction from sinus rhythm during the procedure. The electrocardiographic (ECG) characteristics of CTI-dependent AFL occurring during LA ablation have not been described. The purpose of this study was to describe the ECG features of CTI-dependent AFL occurring during percutaneous LA catheter ablation for AF.

 Aims We investigated the utility of real-time stroke volume (SV) monitoring via the arterial pulse power technique to optimize cardiac resynchronization therapy (CRT) parameters at implant and prospectively evaluated the clinical and echocardiographic results.

BACKGROUND: Prior investigators note successful ablation of both typical cavotricuspid isthmus-dependent and scar-related macroreentrant right atrial flutters (AFL) in adult patients with repaired tetralogy of Fallot (TOF). However, an analysis of the mechanisms (including a description of a uniform approach to diagnose such mechanisms), and clinical outcomes of catheter ablation in a consecutive series of adult patients with AFL late after surgical TOF repair has not been previously reported.

 BACKGROUND: Atrial and ventriclar tachyarrhythmias, as well as bradyarrhythmias, in the elderly with heart failure (HF) and/or hypertension (HTN) have been well documented. However, the frequency of these arrhythmias, whether silent or symptomatic, and their association with subsequent cardiac events has not been well defined in patients 65 years or older with HF and other cardiovascular risk factors.

  Long QT syndrome (LQTS) is a hereditary disorder in which the majority of affected individuals present with QT prolongation on electrocardiograms (ECGs), arising from delayed ventricular repolarization. This commonly arrhythmia-associated genetic syndrome can lead to sudden cardiac death (SCD) and increased propensity for arrythmogenic syncope. The authors describe the case of a young patient who presented with episodes of syncope, prolonged QTc interval on ECG, and family history of SCD.

BACKGROUND AND RESEARCH OBJECTIVE: The incidence of cardiovascular disease (CVD) is particularly high among African American (AA) older adults, and these individuals are least likely to have access to CVD prevention activities.
