Effects of Premature Ventricular Complex Burden on Left Ventricular Global Longitudinal Strain in Patients without Structural Heart Disease
Abstract
Background: Evaluation of left ventricular (LV) function in patients with idiopathic premature ventricular contraction (PVC) with preserved LV ejection fraction (LVEF), especially in the subclinical stage, may be of great importance in terms of directing early treatment. Methods: A total of 122 patients, retrospectively recruited, were divided into three groups according to PVC burden: Group 1; 5% ≤ PVC Results: LV-GLS (Global longitudinal strain) was found to be significantly lower in groups 2 and 3 with high PVC burden (18.9% ± 1.4, 17.5% ± 2.1, 16.3% ± 1.3; p p p p Conclusions: PVC burden was an independent predictor of deterioration in LV-GLS. The presence of LV-GLS deterioration due to PVC burden emphasizes the necessity for closer patient monitoring, observation of the response to pharmacological treatment, and evaluation of early invasive treatment strategies in selected patient groups.
