Acute aortic syndromes (AAS) are a series of life-threatening conditions of the aorta. To improve predictability and prevention, we investigated the daily, weekly, monthly, and seasonal variations in the onset of AAS in Liaoning Province, Northeast China.
We collected the clinical data of 1,197 patients treated for AAS at the General Hospital of Northern Theater Command between June 2002 and June 2021. Chi-square goodness-of-fit testing was used to determine whether AAS uniformly occurred.
The average age was 54.93 ± 12.32 years, and 614 patients (51.29%) aged below or equal to 55 years. Nine-hundred-and-five patients (75.61%) were male. The proportions of patients comorbid with hypertension and diabetes were 80.37% and 4.09%, respectively. The peak time of the day for the onset of AAS was between 12:00 and 17:59 (P < 0.001). Furthermore, we found that patients with hypertension had obvious circadian rhythm. AAS had a weekly distribution (P = 0.032), with Sunday and Monday being two troughs. The incidence rate of AAS was low in warmer periods, such as July and August in summer (P < 0.001). The correlation analysis revealed a negative association between the incidence of AAS and the monthly average temperature (P < 0.05).
Our results revealed that AAS displayed circadian and seasonal rhythms in northeast China. AAS peaked between 12:00 and 17:59. Patients with AAS with hypertension had obvious circadian rhythm. Summer was trough season for the onset of AAS. The incidence rate of AAS was negatively correlated with the monthly average temperature.
