A significant (p<0.05) circadian pattern of cardiac death was apparent in a retrospective analysis of 94 cases of sudden cardiac death.1 The incidence of cardiac death peaked in the morning between 09:00 and 12:00 h and was lowest in the evening (18:00 to 21:00 h).1 There was an even stronger relationship with the time of waking, with a 2.6-fold increase in risk in the first 3 hours after waking compared with other times of the day.1 The peak incidence of cardiovascular events also occurs at the time of the EMBPS.2 1.
