- Abstract
This article discusses the potential role of intraplaque hemorrhage (IPH) and coronary spasm in sudden cardiac arrest (SCA) patients with non-obstructive coronary artery disease (CAD). The study included 23 SCA patients who underwent emergency/urgent coronary angiography (CAG) and intracoronary optical coherence tomography (OCT) to evaluate non-occlusive coronary lesions. The results showed that IPH was frequently observed in patients without occlusive coronary lesions, often accompanied by coronary spasms. The study suggests that the interaction between IPH and coronary spasm may contribute to the pathogenesis of SCA. However, the study has limitations, including a small sample size and the absence of a control group. Further research is needed to fully understand the relationship between IPH, coronary spasm, and SCA.
