Study highlights association of IBD with left ventricular, atrial dysfunction, arrhythmias & heart failure

Results: The qualitative analysis comprised a total of 18 studies (14 retrospective and 4 prospective studies) involving 59,838 patients. IBD was associated with subtle systolic and diastolic alterations, vascular dysfunction, increased risk for HF hospitalizations, and globally worse CV outcomes. Nine studies were included in the meta-analysis. In the IBD population, we found statistically significant reduced early to late diastolic transmitral flow (E/A), higher E to early diastolic mitral annular tissue velocity (E/e'), and decreased global longitudinal strain. Increased left atrial diameter and area were also present in IBD patients but no statistical significance was reached. Inter-atrial and right intra-atrial conduction delays were observed.

The IBD population has an increased risk for left ventricular and atrial dysfunction, vascular changes, arrhythmias, and HF hospitalization. Screening with sensitive imaging like speckle tracking echocardiography could identify early subclinical changes. IBD is in fact a CV risk factor and tight inflammation control may reduce CV risk.
