RESUMEN
Availability of an accurate information system in recording and analysis of medical findings obtained from patients with cardiovascular diseases plays a crucial role in fighting cardiovascular diseases. One of the most important approaches in collecting such information is the classification system of cardiovascular diseases. The main goal of this research was to provide effective strategies for establishing a national classification system for cardiovascular diseases in Iran through a comparative study of such national systems currently available in USA, Australia, Canada, and England. This was a descriptive-comparative study conducted during 2007-2008. The classification systems of cardiovascular diseases in USA, Australia, England and Canada were reviewed to provide an appropriate model for Iran. Data collection was performed through literature review, Internet and e-mails. Our findings showed that all selected countries benefit a national classification system for cardiovascular diseases. At present, the systems named as ICD-10-CM in USA, ICD-10-AM in Australia, Rcc in England, ICD-10-CA in Canada, and ICD-10 in Iran are in use. This research attempted to discuss the advantages and the constraints of each system mentioned earlier. Considering our domestic needs, policies and health system priorities, establishing a national classification system for cardiovascular diseases seems to be necessary
