Atrial Conduction Times and Longitudinal Strain of Patients with Chronic Obstructive Pulmonary Disease

Abstract

Objectives: The study aimed to compare atrial electromechanical delay (AEMD), apical 4-chamber longitudinal strain(4C-LS), echocardiographic changes and blood parameters in patients with COPD and control group.Methods: This prospective study was conducted in February and July 2018. The study included 90 (43 females, 47males) patients with acute COPD exacerbation (Group 1), 92 (19 females, 73 males) stable COPD out-patients (Group 2)and 79 (43 females, 36 males) control group patients (Group 3). Demographic features, atrial conduction times, longitudinalstrains, systolic-diastolic functions of right-left heart and blood parameters were compared. Statistical analysiswas carried out using SPSS software.Results: Basal anterolateral, mid anterolateral, apicolateral, apex, apical septal, mid inferoseptal, basal inferoseptal and4C-LS were lower in Group 1. RV basal and mid diameters, Amax, Aa, TRV, SPAP, Emax mitral, Ea mitral, Ea/Aa mitral, Aaseptum and heart rate were significantly higher and RV vertical diameter, TAPSE, Emax/Amax, Ea/Aa, end-diastolic diameter,LVEF, Ea septum, Ea/Aa septum were significantly lower in Group 1. Lateral/mitral AEMD, lateral/tricuspid AEMDand septal AEMD were higher in Group 1 compared to other groups (p
