“The observational, single-blinded, prospective study, published in The International Journal of Cardiovascular Imaging, evaluated the effect of consecutive HBOT treatment protocols on cardiac function in an aging population with “normal for their age” cardiac function. Results indicated an increase in left ventricular ejection fraction following 60 HBOT sessions, and higher global and regional left ventricular strain (efficacy of cardiac muscle contraction), demonstrating this protocol could be used as an effective, sustainable therapy to treat a healthy aging population for improved long-term heart function.”
