The Study of Association Between Handedness, Coronary Dominance and Severity of Lesions in Coronary Artery Branches

Objective: To determine the association between handedness, coronary dominance and severity of lesions in coronary artery branches. Methods: A total of 96 patients (64 male and 32 female) with an ages between (25-76) years old, ages range (51) and age mean ± SD (57.4063± 8.84793)  were diagnosed with ischemic heart diseases a proved by coronary angiography, 32 patients presented with family history to ischemic heart diseases and 64 patients without family history to ischemic heart diseases. Results: The current results showed significance between handedness and coronary dominance (<0.001) and handedness with lesion and severity in left anterior descending, right coronary dominance, left circumflex, and left main stem. Otherwise the family history and sex and coronary dominance with lesion and severity in left anterior descending, right coronary dominance, left circumflex, and left main stem ( <0.001). Conclusion: The study proved the presence of a relationship between handedness and coronary dominance; moreover we suggested there are relations between right handed and right coronary dominance with focal mid lesion in left anterior descending and right coronary.
