PO-06-052 THE OCCURRENCE OF VENTRICULAR SEPTAL SCARRING, HEART FAILURE, AND GENETIC VARIANTS IN PATIENTS WITH NON-ISCHEMIC CARDIOMYOPATHY AND ARRHYTHMIA: RESULTS FROM THE PHOENIX CARDIAC GENETIC REGISTRY (PCGR).

HeartRhythm

Genetic predisposition to ventricular scarring is associated with heart failure and ventricular arrhythmia. Although many pathogenic variants have been shown to predispose patients to poor outcomes, the impact of many VUS remains uncharacterized.

PO-03-084 GENETIC PREDISPOSITION TO ATRIAL FIBRILLATION INCREASES ISCHEMIC STROKE RISK AMONG INDIVIDUALS WITH ATRIAL FIBRILLATION

HeartRhythm

Atrial fibrillation is the most prevalent sustained cardiac arrhythmia and an important risk factor for ischemic stroke resulting in a fivefold increased stroke risk. The clinical utility of polygenic risk scores for ischemic stroke prediction among atrial fibrillation patients has not yet been established.

PO-06-050 THE ASSOCIATION BETWEEN VENTRICULAR ABLATION, SEPTAL SCARRING, AND GENETIC VARIANTS: RESULTS FROM THE PHOENIX CARDIAC GENETIC REGISTRY (PCGR).

HeartRhythm

Genetic predisposition to septal scarring can result in ventricular arrhythmia and poorer ablation outcomes. There is a need to better define these genetic variants to understand clinical implications. Many commonly occurring variants continue to be described as variants of uncertain significance (VUS).

Atrial Fibrillation in Black American Patients: A Review of Genetics, Risk Factors, and Outcomes

HeartRhythm

Atrial fibrillation (AF) is the most common arrhythmia in the U.S., Data pertaining to the American Heart Association Life’s Simple 7 (LS7) health metrics show that Black Americans have suboptimal LS7 scores compared to White Americans on average despite lower genetic predisposition to AF.

The Role of Genetics in Heart Disease Risk

AMS Cardiology

It encompasses a range of conditions, including coronary artery disease, heart failure and arrhythmias. While lifestyle factors such as diet, exercise and smoking play a significant role in the development of heart disease, genetics also contribute substantially.

Sweetened Beverages, Genetic Susceptibility, and Incident Atrial Fibrillation: A Prospective Cohort Study

Circulation: Arrhythmia and Electrophysiology

Circulation: Arrhythmia and Electrophysiology, Ahead of Print. The highest HRs (95% CIs) of AF were observed for participants at high genetic risk who consumed >2 L/wk of ASB (HR, 3.51 [95% CI, 2.94–4.19]), 4.19]), and the lowest HR were observed for those at low genetic risk who consumed ≤1 L/wk of PJ (HR, 0.77 [95% CI, 0.65–0.92]).

Reduced Ejection Fraction in Elite Endurance Athletes: Clinical and Genetic Overlap With Dilated Cardiomyopathy

Circulation

The aim is to assess the prevalence, clinical consequences, and genetic predisposition of reduced EF in athletes.METHODS:Young endurance athletes were recruited from elite training programs and underwent cardiac phenotyping, genetic analyses and clinical events were recorded over a mean of 4.4
