Key result
Variant angina patients with serious arrhythmias during spontaneous attacks had a significantly higher rate of sudden death during follow-up compared to those without (42% vs 6%, p<0.001).
Why the study?

May warrant closer monitoring in variant angina with arrhythmic attacks; leaves open whether suppressing arrhythmias improves survival.
Cohort (n=114)
Are serious arrhythmias during spontaneous attacks associated with sudden death in patients with variant angina?
Absolute Event Rate: 42% vs 6%
p-value: p=<0.001
Miller et al. (1982) conducted a cohort in variant angina (n=114). Serious arrhythmias during spontaneous attacks vs. No serious arrhythmias during attacks was evaluated on Sudden death (p=<0.001). Variant angina patients with serious arrhythmias during spontaneous attacks had a significantly higher rate of sudden death during follow-up compared to those without (42% vs 6%, p<0.001).
