Atrial peak longitudinal strain may be predictive of pancolitis in patients with ulcerative colitis

Abstract

BackgroundUlcerative colitis is a chronic idiopathic inflammatory bowel disease of the colon that is characterized by a relapsing and remitting course. Previous studies have shown that arterial stiffness, carotid intima media thickness, atrial electromechanical delay, and global longitudinal strain suggested subclinical cardiovascular disorders in ulcerative colitis patients. The aims of our study was to evaluate the left atrial function of patients with ulcerative colitis by using speckle tracking echocardiography, and to assess the relationship between echocardiographic variables and the extent of the disease.MethodsWe recruited 51 outpatients with ulcerative colitis in remission phase and 52 healthy volunteers. The ulcerative colitis patients were evaluated by for the extent of the disease by endoscopy at the initial diagnosis.Results E/Em, left atrial volume, and left atrial stiffness index were higher, and peak atrial longitudinal strain was lower in pancolitis than in non‐pancolitis patients. In the multivariate logistic regression test, peak atrial longitudinal strain and E/Em were found to be independent predictors for pancolitis.ConclusionEarly detection of myocardial abnormalities by conventional echocardiography and speckle tracking echocardiography, which is a simple and non‐invasive technique, may be useful for giving insights to the extent of the disease in ulcerative colitis patients.
