Objective: To compare attendance patterns between invasively and non-invasively treated myocardial infarction patients in a cardiac rehabilitation phase 2 program. Also to correlate attendance levels to changes in functional capacity (exercise duration and MET levels).

Subjects: 61 subjects diagnosed with an acute myocardial infarction, or a related diagnosis where an myocardial infarction was suspected, enrolled in a phase 2 cardiac rehabilitation program. The subjects were divided into 2 groups- invasively treated and non-invasively treated for comparison purposes.

Design: Retrospectively study utilizing medical records of patients who had already completed or dropped out of the phase 2 program prior to data collection.

Measures:A one-way ANOVA was used to compare the 2 treatment groups on attendance patterns and a Pearson r correlated attendance to MET level and exercise duration changes. Significance was determined at p

Results: Invasively treated myocardial infarction patients elicited higher attendance values and greater MET level and exercise duration time improvements than their non-invasive counterparts. Male patients also tended to elicit higher attendance values along with greater increases in MET levels and exercise duration times than female patients.

Conclusions: Consistent patient attendance allows for patients to markedly improve their functional capacity. Non-invasively treated myocardial infarction patients tend to elicit less consistent phase 2 attendance thereby inhibiting increases in their functional capacity. Cardiac rehabilitation staff should be aware of how treatment mode influences patient attendance. Future investigations could focus on gender issues in phase 2 programs, long term effects adherence of phase 2 protocols, and depression in phase 2 patients.
