Left Atrial Dysfunction in Chronic Coronary Syndrome

In patients with chronic coronary syndrome, there is a risk of subsequent cardiovascular disease. This link underscores the need to prevent this consequence through the use of surrogate markers. Speckle-tracking echocardiography-derived left atrial reservoir strain is a marker for cardiovascular disease which has been used clinically. Therefore, this study used 278 patients to investigate left atrial dysfunction in chronic coronary syndrome. Specifically, left atrial enlargement has been found to be a marker for cardiovascular events. In this study, 10% of participants were found to have left atrial dysfunction which was associated with adverse cardiovascular events. Factors related to left atrial function in chronic coronary syndrome included disease severity, age and hypertension.

This review by Hirose K et al aimed to understand the link between left atrial dysfunction and chronic coronary syndrome.

Key learnings:

Further research is needed into understand how left atrial dysfunction correlates with cardiovascular events. This can allow for a better understanding of the types of therapeutic interventions that can be used to manage chronic coronary syndrome patients.
