title: Quality of life in cardiovascular patients in iran and factors affecting it: a systematic review.
abstract: BACKGROUND
  Cardiovascular diseases are always one of the major causes of mortality in the world affecting all aspects of patients' lives. Therefore, this study was conducted to summarize and provide a clear view of quality of life in these patients in Iran through a systematic review on the results of previously conducted studies.
  
  
  METHODS
  In a systematic review, required information was collected by searching keywords of Iran, quality of life, heart failure, cardiac, heart, and their Persian equivalents in databases of Science Direct, Pubmed, IRAN doc, SID, Medlib and Magiran. The selected time period for searching articles was since 2000 to 2012. Inclusion criteria were: releasing of article during 2000 to 2012, articles reporting patients' quality of life in any domains of heart diseases, and articles published in Persian and English. Extracted results first were summarized in Extraction Table, and then analyzed manually.
  
  
  RESULTS
  Finally 18 of 1592 found articles were included in the study. A total of 3,797 cardiac patients' quality of life was measured using six different tools, the most important one of which was SF36 questionnaire. Among eight dimensions of SF36 questionnaire, the highest mean was for social role functioning with average score of 58.37 and the lowest for physical limitation (physical role functioning) with score of 42.95. Overall, mean of eight dimensions was 53.19. Among 4 general domains of quality of life, physical activity had the lowest average of 43.63 and average of general dimensions of quality of life was 47.65. The most important factors affecting quality of life were sex, age, education, marital status, occupational status, suffering duration, number of hospitalizations etc.
  
  
  CONCLUSIONS
  The results of the studies showed relatively low quality of life of cardiovascular patients in general. Therefore, according to the introduced effective factors in this study, it is necessary to consider regular programs for improving quality of life in these patients and providing suitable and qualitative services.
