Abstract

Spontaneous coronary artery dissection (SCAD) can be treated conservatively. However, some SCAD patients can develop cardiogenic shock (CS). We evaluated the outcomes of SCAD-related CS using data from a national population-based cohort study from January 1, 2016, to December 30, 2019. In our study of 32,640 patients with SCAD, about 10.6% of patients presented with CS. We found that SCAD patients with CS had higher mortality and greater complications including use of mechanical circulatory devices, arrhythmias, respiratory support, and acute heart failure compared to those without CS. When comparing CS due to SCAD with that due to coronary artery disease, we found that although mortality rates were similar, those with CS due to SCAD were associated with higher risk of use of mechanical circulatory support, major bleeding, blood transfusion, and respiratory failure.
