What is the clinical evidence from this study?

Study design: Cross-Sectional. Population: Polycystic ovary syndrome (PCOS) (n=50). Intervention: High BMI (≥23 kg/m²) vs. Normal BMI (<23 kg/m²). Primary outcome: Heart rate variability (HRV) parameters and hormonal changes.

What does this research mean for the field?

Women with polycystic ovary syndrome (PCOS) exhibit sympathovagal imbalance that is more pronounced in those with a high BMI, although these heart rate variability changes do not significantly correlate with hormonal parameters such as TSH or prolactin. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

High BMI in PCOS links to elevated WHR and HRV metrics versus normal BMI.

Q: What are the key findings of this study?

High BMI women with PCOS had significantly elevated WHR and HRV metrics (SDRR, PNN50, LF, HF, LF/HF ratio) compared to normal BMI women with PCOS, with no significant differences in hormonal levels.

Why the study?

PCOS is linked to metabolic and cardiovascular disturbances in both lean and overweight women, but the relationship between HRV and hormonal changes in normal and high BMI PCOS patients is unclear.

Does high BMI alter heart rate variability and hormonal parameters in women with polycystic ovary syndrome compared to normal BMI?

Population

50 women aged 18 to 35 years with PCOS including 22 high BMI and 28 normal BMI

Comparison

High BMI (≥23 kg/m²) vs normal BMI (<23 kg/m²) in PCOS patients

Design

Cross-sectional study

Key result

High BMI women with PCOS had significantly elevated WHR and HRV metrics (SDRR, PNN50, LF, HF, LF/HF ratio) compared to normal BMI women with PCOS, with no significant differences in hormonal levels.

Overview

May flag autonomic dysfunction in PCOS; leaves open whether HRV predicts outcomes or warrants intervention.

Does high BMI alter heart rate variability and hormonal parameters in women with polycystic ovary syndrome compared to normal BMI?

Population

50 women aged 18 to 35 years with polycystic ovary syndrome, categorized into high (≥23 kg/m²) and normal (<23 kg/m²) BMI groups.

Exposure

High BMI (≥23 kg/m²)

Comparator

Normal BMI (<23 kg/m²)

Outcome

Heart rate variability (HRV) parameters (SDRR, rMSSD, PNN50, NN50, LF, HF, LF/HF ratio) and hormonal changes (TSH, serum prolactin, random blood sugar)surrogate

In women with PCOS, a higher BMI is associated with increased sympathovagal imbalance as measured by heart rate variability, independent of hormonal changes.

Muhammad Yunus Khan (2024) conducted a cross-sectional in Polycystic ovary syndrome (PCOS) (n=50). High BMI (≥23 kg/m²) vs. Normal BMI (<23 kg/m²) was evaluated on Heart rate variability (HRV) parameters and hormonal changes. High BMI women with PCOS had significantly elevated WHR and HRV metrics (SDRR, PNN50, LF, HF, LF/HF ratio) compared to normal BMI women with PCOS, with no significant differences in hormonal levels.
