ABSTRACT
<p><b>BACKGROUND</b>In-stent restenosis (ISR) has become one of the most challenging problems in patients with coronary heart disease. At present, using non-invasive methods to assess ISR is a hot topic. In this investigation we attempted to explore the potential of magnetocardiography (MCG) in diagnosis of in-stent restenosis.</p><p><b>METHODS</b>MCG was analyzed in 52 patients with coronary artery disease for three times before stenting, one month and 7 months after successful intracoronary stenting.</p><p><b>RESULTS</b>The average classification of total maps (ACTM) and the ratio of abnormal maps (RAM) were lower in 1 month after intracoronary stenting compared with that obtained before stent planting (2.91 vs 2.52, 65.74% vs 42.80%, P < 0.01), while complex ventricular excitation index (CVEI) increased from -42.63 to -20.05 (P < 0.01). In ISR subgroup (n = 16), RAM decreased in 1 month after intracoronary stenting compared to it before stenting (68.99% vs 45.26%, P < 0.05). ACTM increased in 7 months compared to that obtained in 1 month after stenting (3.15 vs 2.51, P < 0.05). According to the ROC curve, ACTM showed its unique diagnostic value in restenosis patients. The sensitivity and specificity of ACTM were 80.0%, 69.40%, respectively. Its positive predictive value and negative predictive value were 54.6% and 88.5%, respectively.</p><p><b>CONCLUSIONS</b>After successful intracoronary stenting, most parameters of MCG were improved. ACTM was of prognostic value in diagnosing ISR.</p>
