Heart rate variability in type 2 diabetes mellitus: A systematic review and meta–analysis

Open access

Abstract

BACKGROUND: Cardiac autonomic neuropathy in type 2 dibetes mellitus (T2DM) patients is frequent and associated with high cardiovascular mortality. Heart rate variability (HRV) is the gold standard to measure cardiac autonomic neuropathy. We aimed to conduct a systematic review and meta-analysis to evaluate the impact of T2DM on HRV parameters. METHODS: The PubMed, Cochrane Library, Embase and Science Direct databases were searched on 1st October 2017 using the keywords "diabetes" AND ("heart rate variability" OR "HRV"). Included articles had to report HRV parameters in T2DM patients and healthy controls measured during 24 hours with a Holter-electrocardiogram. Measurements of HRV retieved were: RR-intervals (or Normal to Normal intervals-NN), standard deviation of RR intervals (SDNN), percetange of adjacent NN intervals differing by more than 50 milliseconds (pNN50), square root of the mean squared difference of successive RR intervals (RMSSD), total power, Low Frequency (LF), High Frequency (HF) and LF/HF ratio, as per Task Force recommendations. RESULTS: We included twenty-five case-control studies with 2,932 patients: 1,356 with T2DM and 1,576 healthy controls. T2DM patients had significantly (P<0.01) lower RR-intervals (effect size = -0.61; 95%CI -1.21 to -0.01), lower SDNN (-0.65; -0.83 to -0.47), lower RMSSD (-0.92; -1.37 to -0.47), lower pNN50 (-0.46; -0.84 to -0.09), lower total power (-1.52; -2.13 to -0.91), lower LF (-1.08; -1.46 to -0.69]), and lower HF (-0.79; -1.09 to -0.50). LF/HF did not differ between groups. Levels of blood glucose and HbA1c were associated with several HRV parameters, as well as Time from diagnosis of T2DM. CONCLUSIONS: T2DM was associated with an overall decrease in the HRV of T2DM patients. Both sympathetic and parasympathetic activity were decreased, which can be explained by the deleterious effects of altered glucose metabolism on HRV, leading to cardiac autonomic neuropathy.

TL;DR

This systematic review and meta-analysis found that type 2 diabetes mellitus (T2DM) is associated with an overall decrease in heart rate variability (HRV), with both sympathetic and parasympathetic activity reduced. The authors attribute this to deleterious effects of altered glucose metabolism leading to cardiac autonomic neuropathy.

Key findings

Twenty-five case-control studies with 2,932 patients (1,356 T2DM, 1,576 healthy controls) showed significantly lower HRV in T2DM for RR intervals (effect size = –0.61; 95%CI –1.21 to –0.01), SDNN (–0.65; –0.83 to –0.47), RMSSD (–0.92; –1.37 to –0.47), pNN50 (–0.46; –0.84 to –0.09), total power (–1.52; –2.13 to –0.91), LF (–1.08; –1.46 to –0.69), and HF (–0.79; –1.09 to –0.50). LF/HF did not differ between groups (effect size = 0.02; 95%CI –0.38 to 0.43; P = 0.914). Meta-regressions found age and male gender associated with decreased LF and HF; blood glucose and total cholesterol associated with increased LF and HF; higher HbA1c associated with shorter RR intervals; and time from T2DM diagnosis linked with higher SDNN and lower total power.

Methods

Systematic review and meta-analysis of case-control studies reporting 24-hour Holter-electrocardiogram HRV parameters in T2DM patients and healthy controls, following Task Force recommendations. Databases searched were PubMed, Cochrane Library, Embase, and Science Direct (search date reported as 1 October 2017; text also states between 30 October 2015 and 1 October 2017). Random-effects meta-analyses (DerSimonian and Laird) calculated standardised mean differences, with heterogeneity assessed by I² and meta-regressions for clinically relevant variables; study quality was assessed with STROBE and CONSORT.

Limitations

The paper states that meta-analyses inherit limitations of included studies and are subject to selection bias; included studies varied in quality, most were cross-sectional, measurement conditions differed, and inclusion criteria were not identical. The paper also states that control health status was not detailed in all studies, some studies were monocentric, the final number of patients was not very high, and missing or declarative data were potential biases. Evident from the text: heterogeneity was significant for all meta-analyses (e.g., I² = 91.6% for RR intervals, 94.0% for RMSSD, 93.5% for total power), and many variables (HbA1c, BMI, blood pressure, insulin, HOMA-IR, neuropathy scores) were missing or unreported across studies, limiting meta-regression analyses.

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • Study designs described as both prospective cohorts and mostly cross-sectional

    Major

    The study-design section describes all but one study as prospective cohorts, while the limitations section says most included studies were cross-sectional.

  • LF/HF was not significantly decreased

    Minor

    The limitations section says all measured HRV parameters were significantly decreased, whereas the results explicitly say the LF/HF ratio did not differ between groups.

  • Randomized-trial quality range includes a study not identified as randomized

    Minor

    The quality assessment gives a randomized-trial score for study [59], but the study-design section identifies [57] as the sole randomized study.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

A language model drew the claims from the paper on 2026-10-10, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-10-10 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
