We aimed to evaluate the daily, monthly, and seasonal distribution of incident type A of AAD and its association with the variability of specific meteorological parameters, such as atmospheric pressure, temperature, wind and humidity... We defined as onset of the AAD, the earliest time of symptoms as reported by the patient, relatives, or witnesses... The population comprised of 54 patients (mean age 61.2 ± 11.6 years)... The meteorological data collected for the 3 peri-dissection days (the day of the incidence and the two previous days), showed that the onset of AADs is independent of any change in environmental factors [Table 1]... The key element of this study is the high prevalence of AADs in the start of the week and midweekly compared with the prevalence in the weekend [Figure 3]... Emotional stress and job strain have emerged as the precipitating factors for acute coronary events and myocardial infarction, with the trigger mechanism being hypertension... The occurrence of AAD was not associated with rapid alterations in atmospheric pressure, temperature, humidity, and wind in the present study... Moreover, the distribution of AADs did not display seasonal variations... Nevertheless, the daily incidence of AADs revealed an impressive distribution, being significantly more frequent on Mondays than on weekends... Mean values of the weather conditions from the specific day of the aortic dissection were compared to the data of the two days preceding the incidence... Meteorological parameters were compared with one-way analysis of variance (ANOVA)... There were 39 males (mean age 60.9 ± 11.7) and 15 female patients (mean age 62.1 ± 11.6)... Transthoracic echocardiography was initially performed in every patient in the emergency setting; however, the diagnosis of AAD was based on findings from the spiral CT scan... Onset of AADs was independent of any change in environmental factors (not statistically significant).

Figure 1: Monthly distribution of AAD. The frequency in March was found 5 times higher than in May.

Mentions: The population comprised of 54 patients (mean age 61.2 ± 11.6 years). The distribution of dissections through the year is presented in [Figure 1]. while the seasonal and daily variations of AAD are presented in Figures 2 and 3. respectively.
