FERRER CASTRO, Jacno E.; OLIVA CORUJO, Lianne; FONG OCEJO, Marlene  and  ROSELL CASTILLO, Alejandro. Circadian, circaseptal and circannual rhythms in the acute myocardial infarction . MEDISAN [online]. 2013, vol.17, n.10, pp.6046-6052. ISSN 1029-3019.

A descriptive and cross-sectional study of 64 patients with acute myocardial infarction, assisted in "Dr. Joaquín Castillo Duany" Teaching Clinical Surgical Hospital in Santiago de Cuba was carried out during 2008, in order to determine the variability during cardiovascular events, with irregular distribution of the episodes of myocardial ischemia, in relation to the day hours, week or months of the year. Men older than 45 years prevailed in the case material. The ischemic episodes prevailed during the day, in the first 2 days of the week, as well as in the second trimester of the year. The mentioned disorder presented circadian, circaseptal and circannual variations, and its incidence was higher with an increase in age.

Keywords : acute myocardial infarction; circadian rhythm; circaseptal rhythm; circannual rhythm; secondary health care..
