Bibliographie Cannabis et Troubles cardio-vasculaires

Bibliographie Cannabis et Troubles cardio-vasculaires   Dr Christian SUEUR, GRECC, 2e édition, janvier 2020.   Actuellement, les méta-analyses ne montrent pas d'augmentation significative des pathologies cardiovasculaire chez les consommateurs de cannabis. (cf en particulier la méta-analyse de Divya RAVI et coll., Annals of Internal Medicine, 2018). Quoiqu'il en soit, l'existence de facteurs de risques liés à la consommation de cannabis fumé est semble-t-il incontestable; de même, les risques sont vraisemblablement augmentés chez les sujets prédisposés, présentant des pathologies cariaques, vasculaires, des troubles de l'excitabilité cardiaque ou de la tension artérielle. La plupart des "Case Report" consistent en des accidents par sténose vasculaire, cérébrale ou cardiaque, [...]

Regular Cannabis Use Linked to Cardiac Abnormalities, Fran Lowry, Medscape, 2019.

Regular Cannabis Use Linked to Cardiac Abnormalities Fran Lowry Medscape - Dec 30, 2019. https://www.medscape.com/viewarticle/923220?nlid=133282_2052&src=WNL_mdplsnews_200103_mscpedit_psyc&uac=292598PZ&spon=12&impID=2232271&faf=1 Regular recreational use of cannabis is associated with potentially adverse features of left ventricular size and subclinical impairment of left ventricular function, compared with rare or no cannabis use, an observational study concludes. Previous use of recreational cannabis was not associated with such features, suggesting that any deleterious effects may not be permanent. "These are early data which included a relatively small group of regular cannabis users, and the changes we detected were subtle," lead author Mohammed Y. Khanji, MBBCh, PhD, William Harvey Research Institute, NIHR Barts Biomedical Center, Queen Mary University of London, and [...]

Prolonged Cannabidiol Treatment Effects on Hippocampal Subfield Volumes in Current Cannabis Users, Camilla Beale et al., 2018

Prolonged Cannabidiol Treatment Effects on Hippocampal Subfield Volumes in Current Cannabis Users Camilla Beale, Samantha J. Broyd, Yann Chye, Chao Suo, Mark Schira, Peter Galettis, Jennifer H. Martin, Murat Yücel and Nadia Solowij Cannabis and Cannabinoid Research, 2018, 3, 1, 94-107. Doi : 10.1089/can.2017.0047 Abstract Introduction : Chronic cannabis use is associated with neuroanatomical alterations in the hippocampus. While adverse impacts of cannabis use are generally attributed to D9 tetrahydro-cannabinol, emerging naturalistic evidence suggests cannabidiol (CBD) is neuroprotective and may ameliorate brain harms associated with cannabis use, including protection from hippocampal volume loss. This study examined whether prolonged administration of CBD to regular cannabis users [...]

These are the conclusions from a new systematic review and meta-analysis published online today in JAMA Open Network. Lead author Mehrnaz Ghasemiesfe, MD, Northern California Institute of Research and Education, San Francisco, and colleagues explain that they wondered if marijuana smoke might cause [...]
