Influence of Exercise Training on the Left Atrium:Implications for Atrial Fibrillation, Heart Failure and Stroke
Am J Physiol Heart Circ Physiol. 2023 Jul 28. doi: 10.1152/ajpheart.00322.2023. Online ahead of print.ABSTRACTThe left atrium (LA) plays a critical role in receiving pulmonary venous return and modulating left ventricular (LV) filling. With the onset of exercise, LA function contributes to the augmentation in stroke volume. Due to the growing focus on atrial imaging, there is now evidence that structural remodelling and dysfunction of the LA is associated with adverse outcomes including incident cardiovascular disease. In patients with established disease, pathological changes in atrial structure and function are associate...

Pregnancy-Associated Takotsubo Cardiomyopathy Hospitalizations in the United States
Am J Physiol Heart Circ Physiol. 2023 Jul 7. doi: 10.1152/ajpheart.00262.2023. Online ahead of print.ABSTRACTTakotsubo cardiomyopathy (TCM) is most common in postmenopausal women aged ≥ 50 years but also affects pregnant individuals. However, there are no national estimates on the prevalence, timing of occurrence, correlates, and outcomes of Pregnancy-associated TCM. Using the Nationwide Inpatient Sample (NIS: 2016-2020), we describe rates of pregnancy-associated TCM hospitalizations among 13 - 49 years old pregnant individuals in the United States by selected demographic, behavioral, hospital, and clinical characteristi...
