Abstract

OBJECTIVE: Increasing evidence suggests an association between insomnia and cardiovascular disease. We performed a systematic review with meta-analysis of all the available prospective studies that investigated the association between insomnia and risk of developing and/or dying from cardiovascular disease. DESIGN: Systematic review and meta-analysis of prospective cohort studies. METHODS: We conducted an electronic literature search through MedLine, Embase, Google Scholar, Web of Science, The Cochrane Library and bibliographies of retrieved articles up to December 2011. Studies were included if they were prospective, had assessment of insomnia or sleep complaints at baseline, evaluated subjects free of cardiovascular disease at baseline and measured the association between insomnia and risk of developing and/or dying from cardiovascular disease. RESULTS: After the review process 13 prospective studies were included in the final analysis. These studies included 122,501 subjects followed for a time ranging from three to 20 years. A total of 6332 cardiovascular events occurred during the follow-up. Insomnia was assessed through questionnaire and defined as either difficulty of initiating or maintaining sleep or presence of restless, disturbed nights. The cumulative analysis for all the studies under a random-effects model showed that insomnia determined an increased risk (+45%) of developing or dying from cardiovascular disease during the follow-up (relative risk 1.45, 95% confidence interval 1.29-1.62; p < 0.00001), with no evidence of heterogeneity across the studies (I 2: 19%; p = 0.14). CONCLUSION: Insomnia is associated with an increased risk of developing and/or dying from cardiovascular disease.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Studies have shown a significant association between insomnia, mainly "poor sleep", and cardiovascular disease risk.

    “Although these studies have shown a significant association between insomnia, mainly “poor sleep”, and CVD risk, the effect sizes reported were modest and most studies did not include PSG and could not control for SDB.”
  • The estimated risk for incident myocardial infarction and coronary heart disease associated with "poor sleep" or insomnia ranges between 41% and 55%, respectively.

    “and that for incident myocardial infarction (MI) and coronary heart disease (CHD) between 41% and 55%, respectively(176, 177)”

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.

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.
