“…The improvements occurred due to an alteration in sympathovagal rhythm. Their intervention in their study was post-operative, which could be a reason for such changes [9]. Figueiredo et al also found the positive effects of cardiac rehabilitation on heart rate and heart variability in subjects who underwent CABG [10].…”

Objectives: This study was done to find out the impact of a pre-operative physical therapy plan with inspiratory muscle training on functional capacity, kinesiophobia, and post-operative intensive care unit (ICU) stay in subjects with coronary artery disease (CAD) candidates for coronary artery bypass grafting (CABG). Methods: Fifty subjects who fulfilled the inclusion criteria were recruited and randomly distributed into the intervention and control group by concealed envelop method. Participants in the experimental group were provided with inspiratory muscle training (IMT) with breathing exercises and chest clearance techniques, while the control group received breathing exercises and chest clearance techniques. Both groups received three treatment sessions before their scheduled surgery. The assessment was done at three-time intervals: At baseline, after three sessions, and after surgery. The outcome measures were oxygen saturation, heart rate, respiratory rate, Borg scale of perceived exertion (Borg PRE), Tampa scale of kinesiophobia for the heart (TSKH), and days spent at ICU after CABG. Results: Oxygen saturation, respiratory rate, functional capacity, and pulmonary endurance improved significantly among the treatment groups with a P<0.001 and a large effect size. The pulse rate showed no significant improvement; P and effect size were 0.38 and 0.60, respectively. Kinesiophobia and ICU stay also showed significant changes with a P<0.001. The effect size was large for both kinesiophobia and ICU stay. Discussion: IMT as a component of a pre-operative physical therapy plan can improve oxygen saturation, respiratory rate, functional capacity, and pulmonary endurance in CAD patients going for CABG. IMT reduces the level of kinesiophobia and duration of ICU stay after CABG.

Background: Although solid evidence has indicated that respiratory symptoms are common amongst patients with chronic heart failure (CHF), state-of-the-art cardiac rehabilitation (CR) programs do not typically include management strategies to address respiratory symptoms. This study investigated the effect of the addition of breathing exercises (BE) to the CR programs in CHF. Methods: In a two parallel-arm randomized controlled study (RCT), 40 middle-aged patients with CHF and respiratory symptoms were recruited and randomized into two equal groups (n = 20); group (A): standard CR with BE and group (B): standard CR alone. Primary outcomes were respiratory parameters and secondary outcomes included cardiovascular and cardiopulmonary outcomes. All the participants attended a program of aerobic exercise (three sessions/week, 60–75% MHR, 45–55 min) for 12 weeks, plus educational, nutritional, and psychological counseling. Group (A) patients attended the same program together with BE using inspiratory muscle training (IMT) and breathing calisthenics (BC) (six sessions/week, 15–25 min) for the same duration. Results: There was a significant improvement in the respiratory outcomes, and most of the cardiovascular and cardiopulmonary outcomes in both groups with a greater change percentage in group A (p < 0.05). Conclusions: These results indicate that the addition of BE to the CR programs in CHF is effective and is a “patient-centered” approach.
