title: Quality of life in patients with coronary heart disease after myocardial infarction and with ischemic heart failure.
abstract: BACKGROUND
  Quality of life measures are useful when interventions or treatments are indicated for several reasons such as improvement of physical functioning, pain relief, to estimate the effectiveness of therapies or to predict mortality. The aim of the current study was to describe quality of life in patients with stable coronary artery disease, myocardial infarction and heart failure and to evaluate the relationship between depression and health-related quality of life.
  
  
  METHODS
  Patients after STEMI, with stable coronary artery disease, and heart failure (n = 332) completed the MacNew Heart Disease Health-related Quality of Life Questionnaire and the Hospital Anxiety and Depression Scale.
  
  
  RESULTS
  Patients with myocardial infarction had significantly higher scores than patients with stable coronary artery disease or heart failure on the MacNew global scale (p < 0.001) and the physical (p < 0.001), emotional (p < 0.001) and social (p < 0.001) subscales. The anxiety scores were significantly higher in the group of patients with stable coronary artery disease than in patients with myocardial infarction (p < 0.05). The depression scores were significantly higher in patients with heart failure (p < 0.01).
  
  
  CONCLUSIONS
  In patients with stable CAD, anxiety correlated mainly with symptoms, i.e. angina, than with the history of MI. Patients with symptoms of angina react to the illness with anxiety more than depression, whereas patients with heart failure with dyspnea react to the illness with depressive symptoms more than anxiety. In patients after MI and with stable CAD, cognitive-behavioral techniques could be useful to quickly reduce the level of anxiety, while patients with heart failure require long-term support therapy to reduce the risk of depressive symptoms.
