Key result
Specific genetic variants linked to increased SCD risk, supporting screening in at-risk individuals.
Why the study?
Cardiomyopathies and primary arrhythmogenic disorders are the most common causes of sudden cardiac death in young individuals, and genomic studies have identified numerous genetic variants associated with cardiovascular diseases.

Supports screening consideration in family history cases; leaves open prospective validation before practice change.
This review highlights the critical role of genetic screening in identifying individuals at risk for sudden cardiac death due to inherited cardiomyopathies and channelopathies, enabling early targeted intervention.
Brestovac et al. (2025) studied this question. Specific genetic variants are significantly associated with an increased risk of sudden cardiac death, highlighting the need for genetic screening in at-risk individuals.
