Backgroud and Aims: Hypertension (HTN) is a multifactorial chronic disease.Considering the high prevalence rates of this disease, treatment of HTN is necessary, not only to reduce blood pressure (BP) levels but also to prevent the development of cardiovascular, cerebrovascular, and kidney diseases. This treatment can be through medication, which will be determined according to the BP values, obtained either in medical consultations or at home; presence of cardiovascular risk factors, and the presence of target organ damage identified during anamnesis. The aim of this systematic review and meta-analysis is to summarize the effects of device-guided slow breathing (DGSB) and nondevice-guided slow breathing (NDGSB) on BP levels of patients with HTN.Methods: This study is a systematic review and meta-analysis of randomized clinical trials, pertaining to hypertensive patients, with or without comorbidity, over 18 years old, of both sexes, and with or without hypertensive medication. The selected studies showed comparisons between groups that performed DGSB and/or NDGSB with control conditions. The primary outcome was the value of systolic blood pressure (SBP) and diastolic blood pressure (DBP) after the interventions.Results: Twenty-two studies involving 17,214 participants were included in the quantitative analysis. Considerable heterogeneity was revealed between studies.

Background Physiotherapy can include both device-guided slow breathing (DGSB) and nondevice-guided slow breathing (NDGSB) in the treatment of systemic arterial hypertension. Objective The aim of this study is to summarize the effects of DGSB on blood pressure levels of patients with hypertension based on the published literature to date. Methods A systematic search of all published randomized controlled trials (RCTs) on the effects of device-guided and nondevice-guided slow breathing in patients with hypertension, without language restriction, was carried out up to a publication date of January 2020 in nine databases: PubMed/MEDLINE, Latin American and Caribbean Health Sciences Literature (LILACS), EMBASE, CENTRAL (Cochrane Central Register of Controlled Trials), Physiotherapy Evidence Database (PEDro), CINAHL (Cumulative Index to Nursing and Allied Health Literature), Scopus, Web of Science, and Livivo. Clinical trial records databases (ClinicalTrials.gov), and bases for the open gray literature, including Gray Literature Report and ProQuest Central (Citation, Abstract or Indexing, and Dissertations and Theses), were also searched for potentially eligible RCTs. The quality assessment of the included studies will be performed using the Cochrane Risk of Bias Tool for Randomized Trials. The overall quality of the evidence for each outcome will be assessed using the GRADE (Grading of Recommendations, Development and Evaluation) system. Results As of December 2021, the review was completed and all data from continuous variables referring to blood pressure values (mmHg) were synthesized. Conclusions This systematic review will provide a summary of the current evidence on the effects of both DGSB and NDGSB on blood pressure levels. This information can contribute to decision-making by health professionals related to the use of these interventions in patients with hypertension.

UNSTRUCTURED Introduction: Physiotherapy can include both device-guided slow breathing and device-guided slow breathing in the treatment of systemic arterial hypertension. Methods: A systematic search of all published randomized controlled trials on the effects of device-guided and non-device-guided slow breathing on hypertensive patients, without language restriction, will be carried out until January 2020 in nine databases: Pubmed / MEDLINE (Medical Literature Analysis and Retrieval System Online), Latin American and Caribbean Health Sciences Literature (LILACS), EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), Physiotherapy Evidence Database (PEDro), Cumulative Index to Nursing and Allied Health Literature ( CINAHL), Scopus, Web of Science, Livivo, as well as a search of clinical trial records databases, CT.GOV (Clinical trials.Gov), and bases for the Open Grey gray literature, Gray Literature Report, ProQuest Central (Citation, Abstract or Indexing and Dissertations and Theses). In all of these databases, potentially eligible studies including completed and ongoing ECAs were researched. The quality assessment of the included studies will be conducted using the Cochrane Risk of Bias Tool for Randomized Trials. The overall quality of the evidence for each outcome will be assessed using the Grading of Recommendations, Development and Evaluation (GRADE) system. Discussion: This systematic review will provide a summary of the current evidence on the effects of both device-guided slow breathing and device-guided slow breathing on blood pressure levels. This information can contribute to decision making by health professionals related to the use of these interventions in hypertensive patients. Following the guidelines, this systematic review protocol was registered with the Prospective International Register of Systematic Reviews (PROSPERO) number CRD42020147554.
