Key result
Multimodality diagnostics identify severe left main and LAD vasospasm in a 51-year-old OHCA patient.
Why the study?
Coronary artery vasospasm is an under-recognized yet fatal condition that can manifest as sudden cardiac arrest, highlighting the need for a multimodality diagnostic approach.

A multimodality diagnostic approach, including provocative testing, is crucial for identifying coronary vasospasm in patients presenting with unexplained sudden cardiac arrest.
Coronary artery vasospasm is an under-recognized yet fatal condition that can manifest as sudden cardiac arrest. A 51-year-old man presented with out-of-hospital cardiac arrest due to ventricular fibrillation during exercise. Coronary angiogram showed severe disease at ostial left main coronary artery and left anterior descending artery (LAD), that was not present anymore on repeated angiography and intravascular ultrasound assessment. Cardiac magnetic resonance demonstrated evidence of prior myocardial infarction in the LAD territory. Acetylcholine challenge test was performed that induced severe left main coronary artery and LAD spasm. Coronary artery vasospasm has contributed to a significant proportion of patients presenting with coronary artery disease. Establishing the correct diagnosis is detrimental to future management of patients. This case highlighted a multimodality approach in the diagnosis of coronary vasospasm.

Wong et al. (2024) conducted a case report in Coronary artery vasospasm (n=1). Multimodality diagnostic approach was evaluated. A multimodality diagnostic approach successfully identified severe left main and LAD coronary vasospasm in a 51-year-old man presenting with out-of-hospital cardiac arrest.
