Abstract: Arthrosclerosis is the major cause of cerberovascular accidents and major problems of industrial countries. In USA %75 of peoples suffered from it and it causes %42 of all deaths in developing countries such as India. As such as developed countries growth in life standards and socioeconomic levels is yield that cardiovascular disease be as a threaten fact to life. Despite a lot of many efforts on decreasing metabolic risk factors of cardio vascular deaths, Decrease in mortality from cardiovascular disease has reached to plateau level. In USA not only mortality from chronic disease such as arthrosclerosis but also mortality from infectious disease has a reverse relationship with economic and educational level of people. For this reason relation of MI with other risk factors such as infections were been interested. This was a case- control study. Sixty patients with MI and 60 matched cases were selected from other words of Boali hospital. All of the patients whom bean admitted with myocardial infarction diagnosis in the time of study selected and information`s about them recorded in a researcher made questionnaire. Serum sample from patients and control case were sent to determinations of IgG Anti Chlamydia antibodies with enzyme immune assay. Control case were selected from other words of hospital with matching in go and sex and same test in serum sample was done. Sixty patients and 60 controls were evaluated. In any groups 48 persons (80%) were men and 12 persons (20%) were women. Mean ago of cases were so 58.83+/-12.6 (SD) and mean ago of con tools were 59.08+-11.59.All of the patients in any groups had anti Chlamydia antibodies (IgG) (titer great her than 5U mL»1). Difference of means IgG level in two groups in t test was not significant t (p value %85). In this study all of the cases and controls had anti Chlamydia antibodies. (IgG) that maybe related to cold temperature and high level of population co existence in cold seasons.
