The effect of breathing exercise on hemodynamics and heart rate variability parameters in hypertensive patients: A systematic review.

Several types of breathing exercise (BE) have demonstrated effect on hemodynamics and heart rate variability (HRV) parameters in hypertension (HT). However, the effectiveness of each breathing pattern requires greater study. The purpose of this review is to explore the benefits of BE in hypertensive patients.

Body Positions Alter Hemodynamics and Respiration in Healthy Adults: A Systematic Review and Meta-Analysis.

Objective Different body positions can exert both positive and negative physiological effects on hemodynamics and respiration. This study aims to conduct a literature review and examine hemodynamic and respiratory alterations to different body positions.Methods The study protocol was registered with the International Prospective Registry of Systematic Reviews (register no.

20-Hydroxyecdysone attenuates cardiac remodeling in spontaneously hypertensive rats.

Background: Ecdysteroids, a group of steroid hormones found in insects and many plants, have been shown to prevent various changes in mammalian tissues after female sex hormone deprivation.

Purpose: To examine whether an ecdysteroid, 20-hydroxyecdysone (20-HE), exhibits regulatory or protective roles in the cardiovascular system.

Study Design/method: Blood pressure and cardiac function were evaluated in spontaneously hypertensive rats (SHR) during and after daily treatment with 20-HE for six weeks.
