What is the quality of life and what factors influence it in patients 5 years after myocardial infarction compared to a normal population?
Five years after myocardial infarction, most patients are well-adjusted with a relatively high quality of life, though those with residual symptoms like angina, dyspnea, or anxiety experience significant impairments.
In 539 patients 5 years after myocardial infarction (MI), quality of life and factors influencing life quality were studied. All patients originally participated in an early intervention trial with metoprolol. A cardiac follow-up questionnaire and the Nottingham Health Profile were answered by 82%. In the former, information about subjective symptoms, smoking, work and current medication was obtained; the latter described health-related quality of life in terms of energy, sleep, emotions, mobility, pain and social isolation. The rate of and the reasons for rehospitalization were registered in the patients' records. The MI patients reported a comparatively high quality of life. Compared with 'normal' population, a decrease was noted in energy, sleep and mobility, and in sex life, hobby-activity and holiday activity. A nonparametric multivariate analysis disclosed that dyspnoea, angina pectoris and anxiety were closely associated with decreased quality of life. In conclusion, 5 years after MI most patients seemed well-adjusted. Impaired quality of life was reported by patients suffering from angina pectoris, dyspnoea and emotional distress. No relationship was found between health-related quality of life and the beta blocker, metoprolol, which was the most frequently used drug.
Wiklund et al. (Mon,) studied this question.
