Analysis of agreement between cardiac risk stratification protocols applied to participants of a center for cardiac rehabilitation

Abstract

BackgroundCardiac risk stratification is related to the risk of the occurrence of events induced by exercise. Despite the existence of several protocols to calculate risk stratification, studies indicating that there is similarity between these protocols are still unknown.ObjectiveTo evaluate the agreement between the existing protocols on cardiac risk rating in cardiac patients.MethodThe records of 50 patients from a cardiac rehabilitation program were analyzed, from which the following information was extracted: age, sex, weight, height, clinical diagnosis, medical history, risk factors, associated diseases, and the results from the most recent laboratory and complementary tests performed. This information was used for risk stratification of the patients in the protocols of the American College of Sports Medicine, the Brazilian Society of Cardiology, the American Heart Association, the protocol designed by Frederic J. Pashkow, the American Association of Cardiovascular and Pulmonary Rehabilitation, the Société Française de Cardiologie, and the Sociedad Española de Cardiología. Descriptive statistics were used to characterize the sample and the analysis of agreement between the protocols was calculated using the Kappa coefficient. Differences were considered with a significance level of 5%.ResultsOf the 21 analyses of agreement, 12 were considered significant between the protocols used for risk classification, with nine classified as moderate and three as low. No agreements were classified as excellent. Different proportions were observed in each risk category, with significant differences between the protocols for all risk categories.ConclusionThe agreements between the protocols were considered low and moderate and the risk proportions differed between protocols.

Functional electrical stimulation improves muscle strength and endurance in patients after cardiac surgery: a randomized controlled trial

“…Cardiac rehabilitation (CR) aims to optimize physical and psychosocial recovery after a cardiac event and to reduce the risk of a subsequent event through changes in lifestyle for these patients. 1 , 2 Physical training is an important part of the CR program and aims to improve exercise capacity and physical functioning regarding limitations to individual physical activities. 3 However, some patients do not tolerate even low levels of exercise and therefore tend not to engage in conventional physical training programs.…”

FORCE Risk Stratification Tool for Pediatric Cardiac Rehabilitation and Fitness Programs

“…Globally, there is not uniform adoption amongst the options for adult programs [ 7 ]. Additionally, some authors have looked at adding further modi ers such as a comorbidity index [ 12 ] for factors beyond cardiovascular elements.…”

“…22), a core strength assessment measured in seconds, increased from a median of 35[15, 45] to 52[23, 61] seconds or by 51% change from baseline to 60 days (p < 0.001). Number of push-ups, an upper body strength assessment, increased from 7[3, 10] to 10[7,15] or by 78% from baseline to 60 days (n = 20, p = 0.005). Improvements were also seen in cardiopulmonary exercise test variables.…”

Novel approaches to the assessment of cardiorespiratory readiness of patients after coronary artery bypass surgery aimed to the efficient cardiac rehabilitation performance

“…Это протокол Американской ассоциации по сердечнососудистой и легочной реабилитации, протокол Американского колледжа по спортивной медицине, Американской ассоциации сердца, протокол Фредерика Пашкова, протоколы Бразильского общества кардиологов, Французского общества кардиологов и 2 протокола Испанского общества кардиологов [14][15][16][17][18][19][20]. Анализ этих программ показал отсутствие единых стандартов и полной согласованности в данном вопросе [21] М. Paul-Labrador и соавт. [23] провели анализ, могут ли протоколы по стратификации риска Американской ассоциации по сердечной и легочной реабилитации и Американской ассоциации сердца представлять ценность в прогнозе осложнений во время физических тренировок.…”
