Cardiology genetic testing examines an individual’s DNA to detect inherited mutations that increase the risk of heart diseases, such as hypertrophic cardiomyopathy, dilated cardiomyopathy, arrhythmias (like Long QT syndrome), and familial hypercholesterolemia. By identifying specific genetic variants, this test helps clinicians diagnose conditions that might not be apparent through standard exams or imaging. It is particularly useful for individuals with a family history of sudden cardiac death, unexplained heart failure, or early-onset heart disease. Results guide personalized treatment, risk stratification, and family screening, enabling targeted prevention and management to improve patient outcomes and reduce complications.
