Abstract :
Introduction
Hypertension (HTN), owing to high prevalence rate
poses a significant health threat. Untreated HTN is a
major risk factor for developing coronary artery disease.
However, early intervention reduces the risk of
complication. Breathing exercises (BE) has been gaining
importance due to its potential role in enhancing
autonomic function in HTN. This systematic review aims
to evaluate the impact of BEs on heart rate variability
(HRV), a clinical marker of autonomic nervous system
function, in patients with HTN.
B. Objective
To assess the impact of different types of BE used in
management of HTN and their effects on HRV
parameters.
C. Methodology
Studies evaluating the changes in HRV following
BE involving hypertensive individuals, aged 18-70 years
of both sexes were included in the review. Data were
extracted from various scientific database. Risk of bias
was assessed using standard protocol and the results
were analysed.
D. Results:
A total of 7 studies, including both Randomized
Control Trials and observational studies, were analyzed.
Following the BE, the studies demonstrated significant
improvements in HRV, with increased parasympathetic
activity (higher RMSSD, SDNN, pNN50, and HF) and a
reduction in the LF: HF ratio. Despite the type and
duration of breathing techniques that were employed, all
were found to be beneficial in improving autonomic
function.
E. Discussion:
BE significantly enhance vagal tone, which helps in
the reduction of blood pressure. The results suggest that
regular practice of BEs would serve as an adjuvant
therapy in treating HTN. However, more robust study
with huge sample size and standard protocol are
essential to study the long-term effects of BE on
autonomic function in hypertensive individuals.
