Recent Advances on the Genetics of Spontaneous Coronary Artery Dissection

Area of Science:

• Cardiology
• Genetics
• Internal Medicine

Background:

• Spontaneous coronary artery dissection (SCAD) is a key cause of acute myocardial infarction, particularly in young to middle-aged women.
• SCAD patients typically present with fewer cardiovascular risk factors compared to those with atherosclerotic causes.
• Underdiagnosis and misdiagnosis of SCAD are prevalent due to limited healthcare provider awareness.

Purpose of the Study:

• To review recent findings on genetic factors associated with SCAD.
• To explore potential genetic underpinnings of SCAD pathogenesis.
• To suggest future research strategies for understanding the genetic basis of SCAD.

Main Methods:

• Review of recent publications on genetic factors in SCAD.
• Analysis of exome sequencing and genome-wide association studies.
• Examination of familial SCAD cases and candidate gene pathways.

Main Results:

• Previous searches for highly penetrant mutations yielded low results, often implicating genes in other hereditary syndromes.
• Recent genetic studies, including exome sequencing and GWAS, have identified potential leads for SCAD pathogenesis.
• Familial SCAD cases suggest a possible genetically triggered etiology in some individuals.

Conclusions:

• The genetic basis of SCAD is not fully understood, but emerging research points to both rare and common genetic factors.
• Further investigation into genetic predispositions is crucial for improving SCAD diagnosis and management.
• Future strategies should integrate advanced genetic approaches to elucidate the full genetic architecture of SCAD.
