However, its efficacy across disorders remains uncertain. This study aims to assess the impact of rapid 350\u2010 to 500\u2010mL water intake on systolic and diastolic blood pressure (BP) and heart rate (HR) through a systematic review and meta\u2010analysis.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec xml:lang=\"en\">\n            <jats:title>Methods and Results<\/jats:title>\n            <jats:p xml:lang=\"en\">We systematically reviewed MEDLINE and Embase up to June 2023, including randomized controlled trials and prospective cohort studies. Using random\u2010effects meta\u2010analysis, we calculated pooled mean differences (MDs) for maximum hemodynamic effects of rapid 350\u2010 to 500\u2010mL water bolus consumption. Participants with orthostatic hypotension experienced increased systolic BP (MD, 24.18 [95% CI, 15.48\u201332.88]) and diastolic BP (MD, 11.98 [95% CI, 8.87\u201315.09]) with decreased HR (MD, \u22123.46 [95% CI, \u22125.21 to \u22121.71]). Similar results were observed in multiple system atrophy and pure autonomic failure subgroup analysis. Healthy participants showed modest increases in systolic BP (MD, 2.33 [95% CI, 1.02\u20133.64]) and diastolic BP (MD, 2.73 [95% CI, 1.15\u20134.30]), but HR changes were not significant (MD, \u22122.06 [95% CI, \u22125.25 to 1.13]). Water had no significant hemodynamic effects in patients with seated or supine postural tachycardia syndrome, although standing effects were unassessed. Our data do not exclude water's potential standing effect in postural tachycardia syndrome.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec xml:lang=\"en\">\n            <jats:title>Conclusions<\/jats:title>\n            <jats:p xml:lang=\"en\">In patients with orthostatic hypotension, rapid water intake elevated short\u2010term systolic BP and diastolic BP, with mild HR reduction when seated or supine. Healthy participants exhibited similar but milder effects. However, patients with postural tachycardia syndrome did not experience these changes in seated or supine positions. Further research is needed to evaluate the promising impact of rapid water ingestion on patients with postural tachycardia syndrome in a standing position, which was not addressed in our study.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1161\/jaha.122.029645","type":"journal-article","created":{"date-parts":[[2023,11,6]],"date-time":"2023-11-06T11:27:33Z","timestamp":1699270053000},"update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":13,"title":["Hemodynamic Effects of the Osmopressor Response: A Systematic Review and Meta\u2010Analysis"],"prefix":"10.1161","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6165-1611","authenticated-orcid":false,"given":"Oyebimbola A.","family":"Oyewunmi","sequence":"first","affiliation":[{"name":"Department of Cardiac Sciences Libin Cardiovascular Institute, Cumming School of Medicine, University of Calgary AB Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4036-7697","authenticated-orcid":false,"given":"Lucy Y.","family":"Lei","sequence":"additional","affiliation":[{"name":"Department of Cardiac Sciences Libin Cardiovascular Institute, Cumming School of Medicine, University of Calgary AB Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3016-8659","authenticated-orcid":false,"given":"Jill K.
