“…However, the spatial conformation of the atria and ventricles are not a regular geometric shape (10) and the results of two-dimensional Doppler ultrasound measurement are prone to errors (11). Real-time three-dimensional (RT-3DE) ultrasound does not need to assume the geometry of the heart (12) and can display the heart space structure, movement law. And adjacent relationship as well as measuring the volume of the heart in real time (13,14).…”

Background: This study aims to assess the value of two-dimensional speckle tracking imaging (2D-STI) combined with real-time 3-dimensional echocardiography (RT-3DE) in evaluating left heart function in patients with combined ETH and PAF. Methods: A prospective study was designed, and the research period was from January 2017 to January 2020. A PAF observation group comprised of patients with ETH and PAF, a PAF control group of patients with ETH but without PAF, and a healthy volunteer group referred to as the healthy group, each comprised of 50 patients was established. All patients underwent routine ultrasound imaging examination using 2D-STI and RT-3DE. The interventricular septum thickness (IVST), left and right atrioventricular diameter (LAD), left ventricular posterior wall thickness (PWT), left ventricular ejection fraction (LVEF), the mean left atrium peak strain (mSs, mSe, mSa), strain rate (mSRs, mSRe, mSRa), the left ventricular mass (LVM), left ventricular mass index (LVMI), and left atrial total emptying volume (LATEV), the left atrial volume index (LAVI), left atrial total emptying fraction (LATEF), left atrium expansion index (LAEI), left atrium passive ejection fraction (LAPEF), and left atrial active ejection fraction (LAAEF) were calculated. Patients in the PAF observation group received telmisartan combined with rosuvastatin after diagnosis and 12-and 24-month-follow up visits were conducted. During these visits, 2D-STI combined with RT-3DE was used to evaluate cardiac function and each patient's blood pressure was monitored. Results: Patients in the PAF observation group had a significantly longer course of ETH than patients in the PAF control group (13.5±4.4 vs. 10.32±5.6, P=0.002). The comparison of routine 2D-STI and RT-3DE ultrasound indexes among the three groups also showed significant differences (P<0.01). During the 2-year follow-up period, the IVST, LAD, PWT, and LVEF of remaining patients significantly improved as treatment progressed (P<0.05). The LAVI, LATEF, and LAEI also improved significantly as the treatment progressed (P<0.05). After 12 months of treatment, the recurrence rate of atrial fibrillation was 16.33% (8/45) and after 24 months this was 34.21% (13/38).Conclusions: Cardiac function could be evaluated comprehensively by 2D-STI combined with RT-3DE in patients with ETH combined with PAF at initial diagnosis and follow-up. Ethical approvalAll procedures performed in this study involving human participants were in accordance with the Declaration of Helsinki (as revised in 2013). The study was approved by the Clinical Ethics Committee of The Central Hospital of
