LID - S1109-9666(23)00228-2 [pii] LID - 10.1016/j.hjc.2023.12.002 [doi] AB - BACKGROUND: The sodium-glucose transporter-2 (SGLT-2) inhibitor dapagliflozin can improve left ventricular (LV) performance in patients with type 2 diabetes mellitus (T2DM). However, the effects on left atrial (LA) function in treatment-naive T2DM patients remain unclear. The aim of our study was 1) to investigate the effects of 3-month treatment with dapagliflozin on LA function in treatment-naive patients with T2DM using 4-dimensional automated LA quantification (4D Auto LAQ) and 2) to explore linked covariation patterns of changes in clinical and LA echocardiographic variables. METHODS: 4D Auto LAQ was used to evaluate LA volumes, longitudinal and circumferential strains in treatment-naive T2DM patients at baseline, at follow-up, and in healthy control (HC). Sparse canonical correlation analysis (sCCA) was performed to capture the linked covariation patterns between changes in clinical and LA echocardiographic variables within the treatment-naive T2DM patient group. RESULTS: This study finally included 61 treatment-naive patients with T2DM without cardiovascular disease and 39 healthy controls (HC). Treatment-naive T2DM patients showed reduced LA reservoir and conduit function at baseline compared to HC, independent of age, sex, BMI, and blood pressure (LASr: 21.11 +/- 5.39 vs. 27.08 +/- 5.31 %, p(adjusted) = 0.017; LAScd: -11.51 +/- 4.48 vs. -16.74 +/- 4.51 %, p(adjusted) = 0.013). After 3-month treatment with dapagliflozin, T2DM patients had significant improvements in LA reservoir and conduit function independent of BMI and blood pressure changes (LASr: 21.11 +/- 5.39 vs. 23.84 +/- 5.74 %, p(adjusted) < 0.001; LAScd: -11.51 +/- 4.48 vs. -12.75 +/- 4.70 %, p(adjusted) < 0.001). The clinical and LA echocardiographic parameters showed significant covariation (r = 0.562, p = 0.039). In the clinical dataset, changes in heart rate, insulin, and BMI were most associated with the LA echocardiographic variate. In the LA echocardiographic dataset, changes in LAScd, LASr, and LASr_c were most associated with the clinical variate. CONCLUSION: Compared with HC, treatment-naive patients with T2DM had lower LA function, and these patients benefited from dapagliflozin administration, particularly in LA function.
