“…[22]. Where a participant was prescribed a beta‐adrenergic blocking agent, an equation in patients with coronary artery disease was used to estimate predicted maximum heart rate [23]; no predictive equations for healthy older adults or individuals with osteoarthritis are available. Prism (v8.0; GraphPad Software, CA, USA) was used for all statistical analysis.…”

Cardiopulmonary exercise testing in severe osteoarthritis: a crossover comparison of four exercise modalities*

Cardiopulmonary exercise testing is performed increasingly for cardiorespiratory fitness assessment and preoperative risk stratification. Lower limb osteoarthritis is a common comorbidity in surgical patients, meaning traditional cycle ergometry-based cardiopulmonary exercise testing is difficult. The purpose of this study was to compare cardiopulmonary exercise testing variables and subjective responses in four different exercise modalities. In this crossover study, 15 patients with osteoarthritis scheduled for total hip or knee arthroplasty (mean (SD) age 68 (7) years; body mass index 31.4 (4.1) kg.m-2) completed cardiopulmonary exercise testing on a treadmill, elliptical cross-trainer, cycle and arm ergometer. Mean (SD) peak oxygen consumption was 20-30% greater on the lower limb modalities (treadmill 21.5 (4.6) (p < 0.001); elliptical cross-trainer (21.2 (4.1) (p < 0.001); and cycle ergometer (19.4 (4.2) ml.min À1 .kg À1 (p = 0.001), respectively) than on the arm ergometer (15.7 (3.7) ml.min-1 .kg-1). Anaerobic threshold was 25-50% greater on the lower limb modalities (treadmill 13.5 (3.1) (p < 0.001); elliptical cross-trainer 14.6 (3.0) (p < 0.001); and cycle ergometer 10.7 (2.9) (p = 0.003)) compared with the arm ergometer (8.4 (1.7) ml.min À1 .kg À1). The median (95%CI) difference between preexercise and peak-exercise pain scores was greater for tests on the treadmill (2.0 (0.0-5.0) (p = 0.001); elliptical cross-trainer (3.0 (2.0-4.0) (p = 0.001); and cycle ergometer (3.0 (1.0-5.0) (p = 0.001)), compared with the arm ergometer (0.0 (0.0-1.0) (p = 0.406)). Despite greater peak exercise pain, cardiopulmonary exercise testing modalities utilising the lower limbs affected by osteoarthritis elicited higher peak oxygen consumption and anaerobic threshold values compared with arm ergometry.

“…The attenuated HR response in this subgroup may underlie this finding. 23 Several previous studies have evidenced a worse prognosis when impaired chronotropic response is confirmed in ExECG. 24 In line with our results, one study of 5437 asymptomatic women found that all-cause mortality risk was reduced by 3% per increased bpm during ExECG after adjusting for traditional risk factors and exercise capacity.…”

Risk Prediction With ExECG Testing and Stress CMR E7E xercise ECG testing (ExECG) is a widespread and inexpensive technique routinely used in cardiology practice. Because of its limited diagnostic power to rule in or rule out significant coronary artery disease (CAD), 1 it has been downgraded from a first-line diagnostic test to detect ischemia in recent guidelines. 2 Noninvasive imaging tests are the current first-line recommendation in the diagnostic workup of patients with suspected chronic coronary syndrome (CCS). Specifically, vasodilator stress cardiac magnetic resonance (VS-CMR) has become a valuable technique for comprehensive, noninvasive evaluation of patients with CCS in terms of diagnosis, risk stratification, and decision making. This technique can accurately confirm or exclude CAD in a wide range of populations 3 and predict the risk of adverse outcomes with relatively high precision. [4][5][6] This robust demonstration of ischemia and outcomes can subsequently guide patient management, for instance, in the decision to revascularize or not. 7,8 The prognostic value of ExECG in patients has also been well established. 9 Several parameters such as the Duke Treadmill Score can predict the probability of CAD and mortality risk. 10 Contemporary registries show that excellent functional capacity during ExECG can predict a low risk of all-cause mortality 11 and high-risk CAD. 12 Its role in guiding exercise training in cardiac rehabilitation programs has also been important, 13,14 and its diagnostic and prognostic values can be enhanced if cardiopulmonary assessments are incorporated. 15,16 Exercise and cardiopulmonary stress testing are still and will probably continue to be recommended for prognostic evaluation of patients with CCS and other cardiac-related conditions. 2,17,18 However, in the era of increasingly available, more powerful diagnostic techniques such as VS-CMR that can also provide prognostic information in patients with known or suspected CCS, the role of ExECG, even for risk stratification purposes, is unclear. The aim of the present study was to explore whether ExECG can contribute to risk stratification beyond VS-CMR in patients with known or suspected CCS.

“…One explanation for this is that antihypertensive drugs, such as beta-adrenergic blockers, may alter baseline heart rate as well as during exercise [37][38][39] . Oxygen saturation values remained within normal limits during all sessions, indicating that EAT is safe for normotensive and hypertensive individuals.…”

Impact of equine assisted therapy on the cardiovascular parameters of the elderly

Introduction: Physical activity programs in the elderly aim to prevent and/or reduce the functional decline resulting from the senescence process. Several studies provide evidence that Equine Assisted Therapy (EAT) is an effective means of improving health. However, studies addressing the effects of EATon the cardiovascular system are scarce. Objective: To evaluate the effect of Equine Assisted Therapyon the cardiovascular responses of participants divided into two groups: normotensive and hypertensive. Methods: Twenty individuals participated, aged between 60 and 79 years, divided into three groups: Normotensive Group (n=14), Hypertensive Group (n=6) and all participants, Total Group (n=20). The Omron® HEM 742 blood pressure monitor was used to measure blood pressure and the Gerathem® portable finger oximeter to measure heart rate and blood oxygen saturation. Ten visits were made once a week, lasting 30 minutes. Results: Between the first and tenth interventions, there was a reduction in blood pressure and heart rate, with statistical significance of systolic blood pressure for the Hypertensive Group (p=0.0478), the Total Group (p=0.0201) and diastolic pressure for the Total Group (p=0.0421). There was also a statistically significant difference in systolic blood pressure and heart rate during some visits. Blood oxygen saturation increased after the intervention, but without statistical significance. Conclusion: Equine Assisted Therapy can promote a reduction in blood pressure in the elderly, especially hypertensive individuals.
