  1. Abbreviations WHOQOL-BREF World Health Organization Quality of Life, RAND-12 Health Status Inventory; physical and mental component, MIDAS Myocardial Infarction Dimensional Assessment Scale. MIDAS has a range from 0 (best possible health as measured by the scale) through to 100 (worst health as measured by the scale). A paired t-test for RAND-12 scores and an exact marginal homogeneity test for WHOQOL-BREF were used to analyse the difference between scores at baseline and two-month follow-up
