Sudden death from variant angina can occur within days of first onset, highlighting the need to balance diagnostic confirmation with immediate treatment.
Sudden death may occur days after variant angina onset; this case leaves open optimal initial diagnostic versus therapeutic strategies.
We report a case of sudden death due to variant angina during Holter electrocardiogram (ECG) monitoring. The patient, a 60-year-old man, had been aware of chest discomfort lasting less than one minute at midnight 2 days earlier. Because variant angina or arrhythmia was suspected, Holter ECG monitoring was performed. The patient spent a whole day without a recurrence of chest pain before going to bed, but at midnight he developed sudden chest pain, and died immediately after taking a sublingual tablet of isosorbide-dinitrite. Analysis of the Holter ECG revealed ventricular fibrillation after several ventricular premature beats following ST-segment elevation in both the CM5 and NASA leads. This case shows that sudden death from variant angina may occur within a few days after the first onset, and also highlights whether priority should be given to making a definite diagnosis or giving treatment when variant angina is strongly suspected.
