Risk factor reduction behaviours in coronary angioplasty and myocardial infarction patients

A recent study asked percutaneous transluminal coronary angioplasty (PTCA) patients in Saskatchewan (n = 210) to identify specific information surrounding their rehabilitation behaviours and motivation to change lifestyle. The scale used to elicit this information was developed and previously used to determine patient risk factor knowledge and lifestyle change behaviours among myocardial infarction (MI) patients during rehabilitation phases. The purpose of this article is to discuss the results of PTCA patients' responses and compare these findings to previously obtained data from MI patients. Risk factors most frequently reported by both PTCA and MI patients as causative factors of their heart problems included diet, job stress, low levels of exercise, and other patient-perceived factors. When asked about lifestyle restrictions post-hospitalization, PTCA patients reported more lifestyle restrictions in activities of daily living (recreation, job, social life, sexual activity and driving) following hospitalization than MI patients. Both groups of patients reported high levels of dietary changes made post-hospitalization but findings reflected that MI patients had initiated more modifiable risk factor changes overall than PTCA patients. Comparative results showed that MI patients were more likely to initiate risk factor reduction behaviours for modifiable factors such as smoking, weight reduction, job/family stress, and exercise than PTCA patients. These findings offer insight into differences between PTCA and MI patients with respect to cardiac rehabilitation behaviours and may suggest the need for different teaching-learning approaches and/or more focused patient education for PTCA patients. A goal of cardiac rehabilitation is to encourage patient initiation and maintenance of lifestyle modification behaviours based on identified risk factors.(ABSTRACT TRUNCATED AT 250 WORDS)
