BACKGROUND: This is a comprehensive report that has determined the occurrence of @entity583 and @entity951 in " @entity6910 " blood group system among @entity1 with @entity453 in some areas of Sindh province of Pakistan. METHODS: Three hundred @entity1 with @entity301 ( @entity301 ) were selected from cardiology wards of LMC hospital Hyderabad, DMC hospital Karachi and PMC hospital Nawabshah. The @entity1 were separated into two categories: @entity583 and @entity951 . The @entity1 with old @entity583 were also included. A careful history was taken, suggesting @entity583 from a standard WHO (Rose) @entity662 , and a electrocardiogram showing evidence of possible @entity583 and @entity951 , and the @entity1 's recall of a doctor's diagnosis of M.I or @entity951 . @entity6910 blood grouping of above @entity1 was done by simple agglutination method. RESULTS: The blood group "A" was the commonest among @entity583 and @entity951 @entity1 while these diseases were least in blood group "O" @entity1 . CONCLUSIONS: This comparison shows the existence of a direct relation between blood group antigens and @entity453 . It is therefore of great importance for future genetic studies, as present report and our previous studies give clear picture of excess and @entity301 in particular blood groups of " @entity6910 " system. This may be due to some special genetic makeup.

A study of relationship of @entity6910 blood groups with @entity583 and XXXX .
