Popis: Population-based epidemiology and clinical case studies document a prominent 24-hour pattern in the occurrence of silent and non-silent angina pectoris (AP), acute myocardial infarction (AMI), and sudden cardiac death (SCD). When the data are summarized per 3 – 6 hour intervals of the 24 hours, the temporal pattern of these ischemic heart disease (IHD) events shows a single morning peak between 06:00 and 12:00 h in incidence. However, when the occurrence of such events is examined according to the hour of their occurrence, several studies reveal a second late-afternoon/early-evening minor peak. The true day – night pattern in AP, AMI, and SCD is unknown because the data represent nothing more than the recorded “time of day” of the events. It has been postulated that the day – night pattern in IHD events is at least in part dependent on endogenous circadian rhythms, which are synchronized by the daily routine of sleep in darkness/activity in light. Approximately 20% of the working population is in...
