[Cardiogenetics in clinical practice : challenges, indications, and perspectives]

Cardiogenetics plays an increasingly important role in managing cardiovascular diseases, owing to the major impact of genetic data on diagnosis, risk stratification, therapeutic decision-making, and family-based prevention. Many cardiomyopathies, channelopathies, and other entities have a genetic basis, which is often monogenic, with incomplete penetrance and variable expressivity. Genetic analyses, now integrated into international guidelines, must be interpreted in the context of the clinical phenotype and family history, complemented by cardiological screening. Their rational use helps optimize patient management, enables cascade screening of relatives, and paves the way for more personalized and preventive cardiology.
