The effects of climate in patients with arterial hypertension, including in combination with chronic obstructive pulmonary disease and/or bronchial asthma

Abstract

Objective: to examine the characteristics of the regulation mechanisms of the cardiovascular system under the influence of climatic factors of the patients with arterial hypertension (AH) without comorbidity compared to the patients with AH and associated pathology (chronic obstructive pulmonary disease and/or bronchial asthma).Conclusion: during the spring of 2012 – winter of 2013 abnormal summer heat and abnormally low temperatures in winter in the central region of Russian Federation were not observed. Against this background, patients with AH, including with BOD did not have any significant changes of BP and HR in summer compared to those in spring. The increase of the daily average temperature in summer was followed by a significant increase of ventricular extrasystoles. In assessing of the endothelial dysfunction it was proved that it showed a significant deterioration due to hot weather. The best estimation of general health state was noted in winter period according to the VAS. The spirometric parameters of the patients with AH and BOD were significantly better at this time of the year.
