Does climate change affect the chronobiological trends in the occurrence of acute coronary syndrome?


Acute coronary syndromes (ACS) are the leading cause of death all over the world. In the last years, the chronobiology of their occurrence has been changing. Medical records of 10,529 patients hospitalized for ACS in the Medical University of Bialystok, in 2008–2017, were examined. The highest seasonal mean for ACS was recorded in spring and it was the season with the largest temperature changes from day to day (∆ temp. = 11.01). Analysis of weekly changes showed that the highest frequency of ACS occurred on Thursday, while in the STEMI subgroup it was Monday. Sunday was associated with decreased admissions due to all types of ACS.


What are the main findings of our work?

Weather conditions have an impact on ACS frequency and the elderly are more susceptible. We observed a shift in the seasonal peak of ACS occurrence from winter to spring which may be related to temperature fluctuations associated with climate change in this season. The lowest frequency of ACS took place on weekends.
