FEV1 is independently related with impaired left atrial strain in chronic obstructive pulmonary disease patients: A speckle tracking study

Background Atrial fibrillation (AF) is common in chronic obstructive pulmonary disease (COPD) patients. It is known that impaired forced expiratory volume in 1 s (FEV1) is one of the risk factors of cardiovascular disease. Two‐dimensional speckle tracking echocardiography (2D‐STE) can detect deterio...

Description
Summary:Background Atrial fibrillation (AF) is common in chronic obstructive pulmonary disease (COPD) patients. It is known that impaired forced expiratory volume in 1 s (FEV1) is one of the risk factors of cardiovascular disease. Two‐dimensional speckle tracking echocardiography (2D‐STE) can detect deterioration of left atrial mechanical functions in the subclinical stage. We hypothesized that reduced lung functions, measured by FEV1 in COPD patients, may be associated with impaired left atrial (LA) mechanical functions. Objectives Present study included 127 consecutive COPD patients. We divided study population into two groups: patients with normal LA strain (n = 20) or with impaired LA strain (n = 107). Results In univariate logistic regression analysis, age (p: 0.001), FEV1% (p
