Background: The association between cardiac syndrome X (CSX) and non-dominant right coronary artery system (NDRCA) is not well established. This study was conducted to evaluate the same.

Methods: All patients undergoing diagnostic coronary angiography at Manmohan Cardiothoracic Vascular and Transplant Centre, meeting the inclusion criteria, over a period of 18 month were enrolled in the study. Type of coronary dominance and presence of normal or abnormal coronaries were taken into consideration and correlated with the clinical diagnosis of CSX.

Results: A total of 544 patients meeting the eligibility criteria for the study had undergone coronary angiography over the study period. Of these, 104 (19.1%) patients had normal coronaries and were diagnosed to have CSX. In total study population, 86 cases (15.8% of 544) had NDRCA. In comparison, the prevalence of NDRCA was significantly higher in the CSX group (40 out of 104, 38.5%; P value <0.001).
Conclusion: This study demonstrates that the patients with CSX are more likely to have NDRCA than those with obstructive coronary artery disease. (J Clin Prev Cardiol 2015;4(3):54-7)
