Cardiovascular Genetic Medicine: Evolving Concepts, Rationale, and Implementation

摘要

Cardiovascular genetic medicine is devoted to the identification and understanding of cardiac conditions resulting from genetic and genomic mechanisms and to the development and validation of diagnostic and treatment algorithms and guidelines. Cardiovascular genetic medicine clinics now provide expert cardiovascular subspecialty care, genetic counseling and clinical genetic testing, and will eventually provide disease-specific gene or genetic therapies. Currently, the most tractable diagnoses for cardiovascular genetic medicine are the single-gene disorders: the cardiomyopathies, the channelopathies, and others. The recent explosion of genetic knowledge within the single-gene disorders and consequent rapid proliferation of genetic testing enables far greater numbers of individuals to directly benefit from this progress. A compelling rationale exists for this approach: cardiovascular single-gene diseases commonly present with life-threatening events (e.g., sudden cardiac death, heart failure, stroke, etc.), but identification, evaluation, and treatment of individuals with presymptomatic genetic risk has the promise to prevent or ameliorate cardiovascular morbidity and mortality. Cardiovascular genetic medicine programs also anchor training and research, thereby enabling the next generation of academic specialists in cardiovascular genetic medicine to continue to improve cardiovascular health.
