Cardioembolism is among the most important causes of ischemic stroke around the world. A pilotdouble-center study evaluated the subtypes of cardioembolic mechanisms in stroke patients in two differentracial subtypes.Methods: This prospective clinical study was conducted on 100 stroke patients in Mackenzie Hospital in Canadaand 100 stroke patients who were age and sex matched in Ghaem Hospital in Mashhad, Iran in 2007. All of theCanadian patients were of white North American race and all of the Iranian ones of white Persian race. Thediagnosis of ischemic stroke was made by stroke neurologists.Assessment of the cardioembolic mechanisms was made based on the standard method. The frequency ofischemic heart disease, congestive heart failure and atrial fibrillation was detected in the two studied groups.Results: 92 males and 108 females with ischemic stroke were studied. The influence of race on the frequencyrate of ischemic heart disease, congestive heart failure and atrial fibrillation was not significant. However, rheumaticmitral valve disease was significantly more frequent among the Iranian group. The effect of race on thefrequency rate of other cardioembolic mechanisms was not significant in each gender separately. However, atrialfibrillation was significantly more frequent in Canadian females.Conclusions: There was no significant difference in the frequency rate of cardioembolic mechanisms betweenNorth American and Persian stroke patients except for rheumatic mitral valve disease.
