[ survey on the distribution of coronary risk factors based on myocardial perfusion scan and dipyridamol test in patients who referred for myocardial perfusion imaging [MPI] to the Nuclear Medicine Department of Shahrood Imam Hossien hospital]

Early diagnosis and treatment of cardiovascular diseases has an important role in reduction of the mortality and morbidity of cardiac events, in view of increasing rate of these disease states. This cross-sectional study was performed to evaluate the distribution of coronary risk factors in 222 patients. HTN and smoking were more common in women and men, respectively, while no such difference was noted for other coronary risk factors. The average and total number of risk factors were greater in the group with positive dipyridamole test and positive MPI, in comparison with the group with negative dipyridamole test and negative MPI, respectively. Older age was consistent with more positive MPIs, but not with positive dipyridamole stress tests. DM and HTN were more common in positive dipyridamole test group but this was not true for other risk factors. A normal MPI was noted in 43.7% of patients. These findings indicated that coronary risk factors play an important role in appearance of ischemia in dipyridamol and MPI test
