Brief Summary
This observational study aims to provide evidence for identifying those who mostly suffer from LV injury and will help construct an optimal strategy for clinical practice. The main question it aims to answer is: Could acute PTT response surrounding obstructive respiratory events predict the incidence of subclinical abnormalities in LV structure and function in moderate-to-severe OSA patients? Participants who had undergone standard polysomnography and were diagnosed with moderate-to-severe OSA 5 years ago were required to complete the cardiac remodeling and function evaluation.

Outcome Measures
Primary Outcomes (2)
the cardiac remodeling evaluation
The echocardiogram was carried out using machines equipped with a 2.5-MHz probe. All 2D and Doppler images and measurements were obtained in agreement with the European Association of Echocardiography/American Society of Echocardiography guidelines. Measures of LV remodeling included LV end-systolic (LVDs) in centimeters, and end-diastolic diameter (LVDd) in centimeters, interventricular septum thickness at end-diastole (IVSd) in centimeters, LV mass (LVM) in grams. LVM (LVMI) was calculated as the ratio of LVM in grams and body surface area in square meters. LVH was defined as an LVMI of 111 g/m2or 50 g/m2 in males and of 106 g/m2or 47 g/m2 in females.
from October 2023 to May 2024
the cardiac function evaluation
The echocardiogram was carried out using machines equipped with a 2.5-MHz probe. All 2D and Doppler images and measurements were obtained in agreement with the European Association of Echocardiography/American Society of Echocardiography guidelines. Measures of LV diastolic function included the average of the septal and lateral mitral annular descent tissue Doppler velocity (E') in cm/s, early mitral inflow velocity E' in cm/s, and the ratio of E/E'. Measures of systolic function included LV ejection fraction (EF) in percentage using Simpson biplane method of disks in 2-chamber and 4-chamber apical views (a single view was used in cases where one view was technically suboptimal).

Interventions
Eligibility Criteria
Inpatients aged 18 years and older, with moderate-to-severe OSA, who were diagnosed between January 1 2014, and December 31 2019 at The Affiliated Huaian No.1 People's Hospital of Nanjing Medical University, the First Affiliated Hospital of Nanjing Medical University, and the Affiliated Hospital of Xuzhou Medical University.
You may qualify if:
- ≥18 years old;
- Moderate to severe OSA(AHI≥15 times/hour).
You may not qualify if:
- baseline hypoxia;
- other sleep disorders;
- received regular CPAP treatment(on average of ≥ 4 hours for CPAP use per night during the retrospective period);
- the prevalent diseases at baseline might have influenced the results of echocardiographic results: hypertension chronic atrial fibrillation, atrioventricular block, bundle branch blocks, a permanent pacemaker, heart failure, valvular heart disease, pulmonary emboli, abnormal thyroid function, cardiomyopathies, pulmonary hypertension, use of digitalis, use of antiarrhythmic agents, use of beta-blockers, or use of calcium agonists affecting heart rate (HR), including verapamil and diltiazem.
