Thus, it is important to observe that the results from the United States, performed on a large series of more than 89,000 cases, provide further strong confirmation to the data collected in the Italian region of Emilia-Romagna.

Abstract
Kumar and coll. (Int J Cardiol 2015), in a large sample of hospitalizations in the United States, found that most cases (26.5%) occurred in winter, with the highest rate of hospitalizations in January and lowest in July. Some years ago, a study from our group investigated the seasonal pattern of acute aortic disease in the Emilia-Romagna region of Italy. The final sample, years 2000- 2006, was of 4,615 cases (mean age 66.7 ± 13.6 years, 77% males): the distribution by season showed peaks in Autumn and Winter (27%). As for analysis across subgroups, such seasonal pattern was conformed for total sample (p<0.0001), males (p<0.0001), females (p=0.017), <60 years (p<0.0001), 61-74 years (p=0.01), >75 years (p=0.049), hypertensive (p=0.022) and normotensive subjects (p<0.0001), total dissections (p<0.0001), dissections of thoracic (p<0.0001), abdominal (p=0.013), and thoraco-abdominal (p=0.001) aorta. Thus, it is important to observe that the results from the United States, performed on a large series of more than 89,000 cases, provide further strong confirmation to the data collected in the Italian region of Emilia-Romagna.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
