Background: There was limited data about the clinical and ECG characteristics for prediction of new-onset LV dysfunction in patients with frequent idiopathic VPCs >10% in the long-term follow up.
Methods: The Kosin University 24-hours holter monitoring, echocardiography, ECG database were reviewed from 2010 to 2015 to identify patients with frequent VPC(>10%). We analyzed clinical features and the nature of the VPCs by ECG according to new-onset LV dysfunctions in those patients.
Results: Among 373 patients who underwent 24-hours holter monitoring, 203(54.4%) patients had high VPCs burdens(>10%). There was no difference of the baseline characteristics in both groups. In the long term follow-up, VPCs burden was not associated with new-onset LV dysfunction(P=0.17). In univariate analysis, younger age, smaller chamber size including LV and left atrium, higher LVEF at baseline, short coupling interval(CI, CI/sinus cycle length) ratio, and early precordial R-wave transition of VPCs were associated with new-onset LV dysfunction. In multivariate analysis, shorter CI ratio(P=0.037) and higher LVEF at baseline(P=0.05) were independent risk factors for new-onset LV dysfunction with frequent idiopathic VPCs>10%.
Conclusions: VPCs burden was not associated with new-onset LV dysfunction in patients with frequent idiopathic VPCs>10%. Instead, shorter CI ratio and higher LVEF at baseline were associated with new-onset LV dysfunction with frequent idiopathic VPCs>10% in the long-term follow up.
