## Executive GIST (TL;DR)
- This case-control study evaluated **right atrial** structure and function in patients with obstructive sleep apnea hypopnea syndrome (**OSAHS**) using two-dimensional speckle tracking echocardiography (**2D-STE**). - The study enrolled 120 patients with OSAHS and 100 healthy controls; OSAHS patients were stratified by apnea-hypopnea index (AHI) into mild, moderate, and severe groups. - Conventional echocardiography measured right atrial dimensions (superior-inferior diameter, transverse diameter), area, and volume. - **Myocardial longitudinal strain** parameters derived from 2D-STE included reservoir strain (RASr), conduit strain (RAScd), and contraction strain (RASct). - Compared with controls, OSAHS patients showed progressive decreases in **RASr** and **RAScd**, and increases in **RASct** and transverse diameter as disease severity rose (p < 0.05). - AHI correlated negatively with **RASr** and **RAScd**, and positively with **RASct** and transverse diameter (Pearson correlation; p < 0.05). - The authors conclude that patients with OSAHS have significant structural and functional right atrial alterations and that **2D-STE** is a reliable non-invasive tool for early assessment of right atrial dysfunction in OSAHS. - Keywords emphasized by the source include **two-dimensional speckle tracking echocardiography**, myocardial longitudinal strain parameters, and clinical evaluation of the right atrium in OSAHS. - Full-methodological details, imaging protocols, and additional statistical parameters beyond those summarized in the abstract were not reported in the PubMed abstract.

Conventional echocardiography assessed right atrial structure, including superior-inferior diameter, transverse diameter, area, and volume. Myocardial longitudinal strain parameters (reservoir strain (RASr), conduit strain (RAScd), and contraction strain (RASct)) were measured using 2D-STE. Comparisons were made between groups, and patients were further stratified by apnea-hypopnea index (AHI) into mild (5-14 events/h), moderate (15-39 events/h), and severe (≥ 40 events/h) subgroups. Correlation with AHI was assessed by Pearson correlation analysis. **Results:** Compared to controls, the OSAHS group showed progressive decreases in RASr and RAScd, and increases in RASct and transverse diameter with increasing disease severity (_p_ < 0.05). AHI was negatively correlated with RASr and RAScd, and positively correlated with RASct and transverse diameter (_p_ < 0.05). **Conclusion:** Patients with OSAHS exhibit significant structural and functional alterations of the right atrium. 2D-STE provides a reliable, non-invasive method for early assessment and clinical evaluation of right atrial dysfunction in OSAHS patients. **Keywords:** Two-dimensional speckle tracking echocardiography; clinical evaluation; myocardial longitudinal strain parameters; obstructive sleep apnea hypopnea syndrome; right atrial.
