| description | Introduction: Smoking is a worldwide major cause of preventable
morbidity and mortality. Smoking affects the cardiovascular
system by several mechanisms. The present study was planned
to study the effect of smoking on the cardiovascular autonomic
functions among smokers.
Material and Methods: Hundred male subjects who were in the
age group of 25 to 40 years, who included 50 smokers and 50
non – smokers who formed the control group were selected for
the present study. The participant subjects were selected from
among the staff members, residents and the patients from the
routine OPD. Prior informed written consents were obtained from
them after explaining to them, the procedure and the purpose of
the study tests. The Cardiovascular Autonomic Function Tests
were assessed by using a CANWIN AUTONOMIC ANALYSER
which was available in the department.
Results and Conclusion: After applying the ‘Z’-test for the
difference between the two sample means, it was observed
that there was a highly significant difference between the
mean values of the para-sympathetic function tests among the
smokers and the non – smokers (i.e. p<0.01) The Resting Heart
Rate had significantly increased and the Expiration: Inspiration
Ratio, the 30:15 Ratio (Response to standing) and the Valsalva
Ratio had significantly decreased in the smokers as compared
to those in the non – smokers. After applying the ‘Z’-test for the
difference between the two sample means, it was observed that
there was no significant difference between the mean values of
the Postural hypotension test (i.e. p>0.05) and that there was
a highly significant difference between the mean values of the
Sustained handgrip test in the smokers and the non – smokers
(i.e. p<0.01). |
