Background. It as been demonstrated that acute myocardial infarction, sudden cardiac death, stroke, and fatal pulmonary embolism show an increased onset rate during certain periods of the day, week, or year. According to some authors, the highest risk appears to occur in the morning, on weekends and during winter.

Abstract
Background. It as been demonstrated that acute myocardial infarction, sudden cardiac death, stroke, and fatal pulmonary embolism show an increased onset rate during certain periods of the day, week, or year. According to some authors, the highest risk appears to occur in the morning, on weekends and during winter. This paper, therefore, intends to examine whether a circadian, weekly, or annual rhythm in the incidence rate of deep vein thrombosis (DVT) and non-fatal pulmonary embolism (PE) in ageing patients does exists. Methods. A survey was conducted into 212 patients affected by DVT and PE, admitted to the Second Medicine Institute of Padua, Italy, over a period of two solar years. Thromboses were diagnosed via echo-Doppler examination of the legs and pulmonary embolism via perfusive and ventilatory scintiphotographs. Results. In the overall sample, a circadian variation was found, both for deep vein thrombosis (peak at 12:26 hrs, p=0.001), and pulmonary embolism (peak at 10:26 hrs, ...I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
