Evaluation of the impact of atmospheric pressure in different seasons on blood pressure in patients with arterial hypertension

Abstract

Objectives: Atmospheric pressure is the most objective weather factor because regardless of if outdoors or indoors it affects all objects in the same way. The majority of previous studies have used the average daily values of atmospheric pressure in a bioclimatic analysis and have found no correlation with blood pressure changes. The main objective of our research was to assess the relationship between atmospheric pressure recorded with a frequency of 1 measurement per minute and the results of 24-h blood pressure monitoring in patients with treated hypertension in different seasons in the moderate climate of the City of Łódź (Poland). Material and Methods: The study group consisted of 1662 patients, divided into 2 equal groups (due to a lower and higher average value of atmospheric pressure). Comparisons between blood pressure values in the 2 groups were performed using the Mann-Whitney U test. Results: We observed a significant difference in blood pressure recorded during the lower and higher range of atmospheric pressure: on the days of the spring months systolic (p = 0.043) and diastolic (p = 0.005) blood pressure, and at nights of the winter months systolic blood pressure (p = 0.013). Conclusions: A significant inverse relationship between atmospheric pressure and blood pressure during the spring days and, only for systolic blood pressure, during winter nights was observed. of a temperate climate, the assessment was planned in individual seasons. Due to the high prevalence of hypertension problem and its complications in Poland, a study group of patients with hypertension was selected, which had ABPM performed in our center. This study is the first study in Poland, which has evaluated the effect of AP on BP in patients with arterial hypertension on such a scale. The proposed method allowed calculation of the correlation between atmospheric and blood pressure. MATERIAL AND METHODSAveraged atmospheric pressure was determined for each reading of the ABPM parameters. Weather parameters were calculated as the average of the records from the weather station for a period of 5 min -in the range from 2.5 min before reading the ABPM parameters to 2.5 min after reading this parameter. PatientsThe study used ABPM records of patients of the Cardiology Clinic, Biegański Hospital in Łódź, which were performed in the

Association Between Amplitude of Seasonal Variation in Self‐Measured Home Blood Pressure and Cardiovascular Outcomes: HOMED‐BP (Hypertension Objective Treatment Based on Measurement By Electrical Devices of Blood Pressure) Study

“…BP is affected by various measurement conditions such as room temperature, atmospheric pressure, weather changes, and temperature variability, as well as outside temperature. Hours of daylight and the availability of air conditioning or heating are also associated with the amplitude of seasonal variation in BP.…”

Short-Term Changes in Weather and Space Weather Conditions and Emergency Ambulance Calls for Elevated Arterial Blood Pressure

“…A negative effect of low BP on blood pressure levels was also reported in hypertensive patients who did not respond to treatment [6]. A significant inverse relationship between atmospheric pressure and blood pressure during the spring days, and only for systolic blood pressure, during winter nights, was observed in Poland [7].…”

“…BP in the biosynoptic analysis seems to be the most objective meteorological factor having the same influence on us-indoors and outdoors. The decrease in BP reduces blood oxygenation and pulse rate [5], is associated with a higher blood pressure [6,7], and associated with a higher risk of adverse cardiovascular events [8,9]. We failed to find any experiment-based studies in the effect of relative humidity or wind speed on human physiological indices.…”

Weather Conditions and Outdoor Fall Injuries in Northwestern Russia

“…Previous studies of falls have scarcely addressed the role of atmospheric pressure, and only a few reported that atmospheric pressure has an effect on the incidence of hip fractures and trauma admissions [ 19 , 20 ]. However, it is known that low atmospheric pressure can cause headaches, a feeling of dizziness and decreases in blood pressure among weather-sensitive people [ 47 , 48 , 49 ]. The association between dizziness and falls among middle-aged adults was found by Peeters et al [ 50 ] during the analysis of data from population-based cohort studies in Australia and the UK.…”
