ABO-Rh blood groups distribution in cardiac syndrome X patients

Data on frequency distribution of ABO-Rh blood groups in cardiac syndrome X (CSX) patients
are not available. We aimed to investigate the distribution of ABO-Rh blood groups in these patients. Materials
and Methods: A total of 247 CSX patients’ records were reviewed in a cross-sectional study from 2006 to
2010. One hundred forty six patients (59.1%) were female, and the mean patient age was 52 ± 11 years. The
frequency of ABO-Rh blood groups was compared to the frequency of these blood groups in the West-Azerbaijan
province, Iran; general population. Results: Blood groups distribution among CSX patients showed phenotypes
A, B, AB, O and Rh negative as 33.1%, 21.9%, 9.3%, 35.8%, and 7.9%, respectively. According to our results,
there were no differences in ABO-Rh blood groups distribution between CSX patients and normal population.
Conclusion: These data suggest that ABO-Rh blood groups might be unassociated with CSX
