Abstract
Background: The association between conduction disturbances and atherosclerotic coronary
artery disease has been investigated in a few small studies in the early 1970s and the study result
was inconclusive. Thereafter some investigators found in their separate study that a group of
patients with conduction disturbances that required permanent pacemaker who had coronary
atherosclerotic disease that might be responsible for conduction disturbances.
Method: 40 consecutive patients that required permanent pacemaker and 40 control patients were
investigated. The coronary angiographic study was performed in both groups which included
classification of pathological coronary anatomy, qualitative assessment of flow and stenosis
severity.
Results: The location of the lesions was found significantly different between two groups. 14
patients(35%) of 40 study patients had type IV lesion, whereas only 2 patients(5%) of 40 control
patients had type IV lesion (p=0.001). Flow quality was found poor in more patients in study group
specially that had type IV lesion. Severity of the lesions in the LAD & RCA was found identical in
both groups.
Conclusion: It may be concluded that the location of the lesions rather than diffuse coronary
atherosclerosis might be responsible for a subset of patients with conduction disturbances that
required permanent pacemaker.
