EXPRESS: Dependence of seasonal dynamics of cardiovascular events on a climate of a region: a meta-analysis
Abstract
Background
Cardiovascular events (CVEs) occur more often in winter than in summer; however, the dependence of strokes on various meteorological factors remains unclear .
Aims
The purpose of this meta-analysis was to determine the dependence of the circannual dynamics of hospitalizations for hemorrhagic stroke (HS) and ischemic stroke (IS) on seasonal fluctuations in meteorological factors.
Summary of review and conclusions
For our meta-analysis, we selected 20 and 26 publications examining the seasonal dynamics of HS and IS, respectively . The meta-analysis showed that HS occurs more often in winter than in other seasons and does not depend on a region’s climate. The seasonal dynamics of IS are not clearly expressed and are determined by the characteristics of a region’s climate. In a climate without pronounced seasonal dynamics of atmospheric pressure and in wet winters, the vector of IS incidents will not be expressed or slightly shifted toward winter. Low atmospheric pressure in summer is associated with an increased likelihood of IS during this season compared to winter. There was also a relation between IS risk with high relative humidity and a significant decrease in ÏO2 in summer, but there is not enough evidence regarding this association. We did not reveal dependence of the seasonal dynamics of strokes on the amplitude of annual fluctuations in air temperature.
