Cardiac rehabilitation is an effective and safe therapy to be used in the management of clinically stable people following myocardial infarction or percutaneous coronary intervention or who have heart failure. (Anderson L, Taylor RS. Cochrane Database Syst Rev. 2014) Treatment options for cardiac patients have evolved over the years and are more evidence-based. There is a paucity of knowledge of the changing characteristics of the patient who commences cardiac rehabilitation today compared to yesteryears, especially in Australia.

To examine changes in patient s clinical characteristics, risk factor profiles and medication usage who entered a hospital-based cardiac rehabilitation (CR) program over a period of 20 years.
We reviewed and analysed our patients clinical data collected prospectively from January 1995 to December 2014. This included age, gender, entry diagnosis, risk factor profiles, functional capacity, and medication usage, Ten time points of two years duration were selected for comparison of data over this time period. Comparisons were made with similar studies involving trend analysis in CR. Statistical analysis was made using non-parametric tests (Kruskal-Wallis H Test and Mantel-Haenszel Test) for linear trend and correlation. Statistical significance was determined at p<0.05. Analysis was performed using the SPSS software version 19 (IBM SPPS).

This study highlights the changing face of the cardiac patient entering into CR. Despite this study having some congruency with previous studies, novel findings including antidepressant, anti-arrhythmic, anti-coagulant, CCB and nitrate usage, and indicators of quality of life including depression, has not previously been evaluated for temporal trends in CR.
The study highlights the importance of data collection via a minimum dataset for outcome measures in CR. This study also has implications in regards to staff training and CR program redesign for future requirements to meet patient needs and demands. The increasing burden of disease as well as the increased usage of evidence-based interventions, especially cardio-active medications, define the patients accessing CR today and into the future.

Note: There is a break in the time series for statins because the defined daily dose (DDD) for some statins changed between 2006 and 2007. However, the DDD/1,000/day based on the new DDD are available from 2005 and therefore the break in the time series is shown here from 2005.
