Background and Objectives:Physical activity is one of the core components in cardiac rehabilitation and secondary prevention programs. This study investigated the effect of an intervention based on the health action process approach (HAPA) together with family support in the maintenance of physical activity and exercise capacity in coronary heart disease after discharge from rehabilitation.Method and Materials:In this randomized controlled trial, 96 patients with coronary heart disease were randomly assigned to control and intervention groups at the end of a rehabilitation program at Afshar Hospital, Yazd, Iran. HAPA Constructs and family support using a self-reported questionnaire and maximal oxygen uptake through a treadmill exercise test were measured prior to and 4 months after the intervention.Results:HAPA-based intervention together with family support increased scores of HAPA constructs and family support in the intervention group compared with the control group. The results showed that physical activity and exercise capacity in the intervention group was significantly higher than the control group after the intervention.Conclusion:HAPA-based intervention together with family support can be a useful tool for maintenance of physical activity and exercise capacity in coronary heart disease.
ObjectivesThis study aimed to translate, cross-culturally adapt and psychometrically validate a Persian version of the Cardiac Rehabilitation Barriers Scale (CRBS-P) and to identify the main barriers in an Iranian setting.SettingAfshar cardiac rehabilitation (CR) centre, affiliated with the Yazd University of Medical Sciences, in the centre of Iran.DesignThis was a multimethod study, culminating in a cross-sectional survey.ParticipantsInpatient CR graduates who did not attend their initial outpatient CR appointment.MethodThe 21-item CRBS was translated and cross-culturally adapted in accordance with best practices; an expert panel considered the items and previous non-attending patients were interviewed via phone to refine the scale. Next, structural validity was assessed; participants were invited to complete the CRBS on the phone between March 2017 and February 2018. Using exploratory factor analysis (EFA) with principal component analysis extraction and oblique rotation. Second, confirmatory factor analysis (CFA) was used to verify the results; several goodness-of-fit indices were considered. The internal consistency and 3-week test–retest reliability of the scale (5% subsample) were evaluated using Cronbach’s α and intraclass correlation (ICC), respectively.ResultsFace, content and cross-cultural validity were established by the experts and patients (n=50). One thousand and one hundred (40.7%) of the 2700 patients completed the CRBS-P. Structural validity was established by EFA (Bartlett’s test p<0.001; =0.759) and confirmed by the CFA; a four-factor solution with 18 items accounting for 61.256% of variance had the best fit (χ2/df=3.206, root mean square error of approximation=0.061 and Comparative Fit Index=0.959). The internal consistency and test–retest reliability (n=42) of the scale were acceptable (ICC=0.743 95% CI (0.502 to 0.868); overall α=0.797). The top barriers were not knowing about CR, cost and lack of encouragement from physicians.ConclusionThe four-factor, 18-item CRBS-P had good psychometric properties, and hence can be reliably and validly used to measure CR barriers in Iran and other Persian-speaking populations.
Background Cardiovascular diseases are the most common causes of mortality in the world including Iran and are one of the main causes of disability. Cardiac Rehabilitation (CR) is a multidisciplinary program that helps CVD patients recover faster after a heart attack and avoid any subsequent incident . This report determined the current state of CR in Yazd, Iran. Characteristics of the program Hospital-based Afshar CR program in Yazd, Iran, is the only CR facility in Yazd province, which is located in the centre of Iran. Currently, the Afshar CR program has four phases including inpatient, sub-acute, outpatient and maintenance. The CR team includes cardiologists and heart surgeons as physicians, and physical medicine rehabilitation specialist, outpatient and inpatient resident medical officers, psychiatrists, nutritionists, psychologists, physiotherapists and social workers. Discussion Given the facilities and training programs mentioned above, the rate of patient referral to the center by the inpatient CR team during the short life of CR in this center was 60%, the patient participation rate was 6.9% and the enrollment rate was 55%. In addition, over the past three years, 57% of registered patients completed the program. Conclusion The Afshar CR is trying to get closer to the world standard setting. But it seems that it is necessary to develop the standard of CR in Iran based on the culture and socio-economic status of Iranian community.
Background:Cardiac rehabilitation is a combination of integrated programs aimed at improving outcomes in patients recovering from heart events.Objectives:The present study aimed to evaluate the early benefits of supervised exercise training on electrophysiological function of post-ischemic myocardium. In this regard, signal-averaged electrocardiogram (SAECG) was used.Patients and Methods:Between May and September 2012, all patients (n = 100) admitted to our center, with the diagnosis of acute Myocardial Infarction (MI), were enrolled in this study. Every other patient was assigned to two groups receiving either inpatient cardiac rehabilitation plus standard post-MI care (cases) or only standard post-MI care (controls). Electrophysiological function was assessed by SAECG in all the patients at baseline and on the day 5. The patients were considered as having late potential if they had abnormalities in at least two SAECG indices.Results:Cardiac rehabilitation led to significant improvements in QRS duration (P < 0.001), square root of amplitude in the last 40 ms (P < 0.001) and duration of terminal signal with low amplitude (P < 0.001). Cardiac rehabilitation also resulted in amelioration of SAECG parameters; frequency of patients with late potential significantly decreased from 64% to 20% after five days (P < 0.001).Conclusions:Supervised in-hospital exercise training was associated with improvements in SAECG-measured electrical activity post-MI.
Background: Cardiac specialists are arguably the most influential providers in ensuring patients access cardiac rehabilitation (CR). Physician barriers to referral have been scantly investigated outside of high-income settings, and not qualitatively. Aim: This study investigated cardiac specialists’ perceptions of barriers and facilitators to patient CR participation in a low-resource setting, with a focus on referral. Methods: In this qualitative study, focus groups were conducted with conventional content analysis. Thirteen of 14 eligible cardiac specialists working in Yazd, Iran, participated in 1 or both focus groups (n = 9 and n = 10, respectively). The recording of the first focus group was transcribed into a word file verbatim, and the accuracy of the content of all field notes and the transcripts was approved by the research team, which was then analyzed inductively. Following a similar process, saturation was achieved with the second focus group. Results: Four themes emerged: “physician factors,” “center factors,” “patient factors,” and “cultural factors.” Regarding “physician factors,” most participants mentioned shortage of time. Regarding “center factors,” most participants mentioned poor physician-patient-center coordination. In “patient factors,” the subcategories that arose were socioeconomic challenges and clinical condition of the patients. “Cultural factors” related to lack of belief in behavioral/preventive medicine. Conclusions: Barriers to CR referral and participation were multilevel, as in high-resource settings. However, relative recency of the introduction of CR in these settings seemed to cause great lack of awareness. Cultural beliefs may differ, and communication from CR programs to referring providers was a particular challenge in this setting.
