Self-assessment of health before and after a myocardial infarction.

Self-evaluated health represents an important aspect of quality of life that may influence the rehabilitation process after a major illness. However, health is a multi-dimensional concept and relatively little is known about the determinants of, and the interrelationships between the separate aspects of health. In a prospective longitudinal study of myocaridal infarction (MI) patients, two indices of self-evaluated health, maximal physical ability (MPA) and perceived global health (PGH), were used. On the average, both ratings were clearly reduced compared with pre-MI levels even as long as 3-5 yr after the MI. Females and older patients indicated lower MPA before and after the MI, whereas PGH was not related to any sociodemographic variable. The severity of the MI appeared to be of relatively limited importance for self-evaluated health. Heart-related symptoms before and after the MI were more strongly related to lower MPA, whereas non-cardiac health problems and psychological distress more clearly influenced PGH. However, initial illness perceptions were of some importance for both health perceptions. The data suggest that to some extent self-evaluated health can be influenced by educational or psychological support in order to faccilitate readaption and recovery after a MI.
