Abstract
Cardiovascular disease is the most prominent circulation disorder around the world and one of the leading cause of disease burden in developing countries as the three fourth of the global deaths due to coronary heart disease occur in the middle income countries. Extreme cold episodes significantly has its impact on health ,especially on the cardiovascular system by different mechanisms. This is a community based study aimed to detect the influence of the surrounding environmental temperature on cardiac function. Apparent healthy individuals submitted for longitudinal study along winter and Summer seasons.
All subjects undergo specified inclusion and exclusion criteria.
All subjects will be exposed to the following investigations at one of the coldest day in Winter (below 14 º C) and one the hottest day in Summer (above 34 º C ):
-measurement of arterial blood pressure.
-local examination of heart.
-recording electrocardiograph ( ECG).
Results of the present study show significant elevation in the blood pressure, associated with cold weather.On the other hand there were no- significant changes in the heart rate or other ECG findings.
From our results we can conclude that apparently healthy individuals display adaptive functional changes in the cardiovascular system during seasonal variation. Cold weather is associated with slight increase in thearterial blood pressure (systolic and diastolic).
