Cardiac rehabilitation after myocardial infarction: What influences patients’ intentions to attend?
Background : Cardiac rehabilitation ( CR ) programmes have increased their availability and exp and ed their eligibility criteria . This study sought to identify current predictors and reasons influencing myocardial infa rct ion patients ’ pre-discharge intentions to attend CR .  Methods : Patients in this longitudinal , prospect i ve , five site study completed question naires that surveyed their intentions to attend , attendance and main reasons for non-attendance at CR . Results : 84 % of the 1172 patients indicated that they intended to attend CR . Multivariate analyses revealed that age , employment and earlier history of myocardial infa rct ion were significant predictors of intention to attend CR , yet contributed to only a small proportion of the variance . The main reasons given for not intending to attend CR were lack of interest and perception that the programme would not be beneficial . Other obstacles included work , transport or time . A total of 708 ( 60 % ) patients responded at 12 months , and of these , 44 % who did not intend to attend CR had attended . Conclusion : Patient sociodemographic and clinical profile , although significant , are not major predictors of intention to attend CR . Lack of interest and misconceptions regarding CR are cited as key barriers . Some of these seem to have been addressed post discharge as a good proportion of patients who had not intended to attend CR did change their minds and attended . Motivation of patients to participate in CR , including the identification of barriers and the provision of comprehensive information about the purpose and varied formats of CR programmes , could be used to help further address barriers to attendance
