Relationship between coronary artery calcinosis revealed by electron-beam computed tomography and results of transluminal coronary angioplasty in patients with ischemic heart disease

Aim. To study the relation ship between degree of coronary calcification me asured by electron-beam computed tomography and outcomes of percutaneous tr ansluminal coronary angioplasty. Material and methods. Eighty patients with 96 coronary artery stenoses were subjected to balloon angioplasty and foll owed up for 6 months. Before intervention all patients were examined with e lectron-beam computed tomography. Restenosis was verified by coronary angio graphy. Results. Among patients with complications and restenosis the avera ge calcium score in coronary artery segments subjected to angioplasty was s ignificantly higher than among patients without complications and restenosi s. Applying ROC-analysis we determined sensitivity and specificity of elect ron-beam computed tomography for prediction of complications and restenosis after intervention and critical value of the calcium score in dilated segm ent, associated with high risk of complications and restenosis.
