Abstract
Aims: Obstructive sleep apnea (OSA) is common in type 2 diabetes mellitus (T2DM), but its association with cardiac structure and function in advanced diabetic kidney disease (DKD) remains unclear.
Methods: T2DM patients with estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2 and albuminuria were assessed for OSA using the apnea-hypopnea index (AHI). Cardiac structure and function were assessed by transthoracic echocardiography following standard guidelines. 39 patients without OSA (AHI < 5) were compared to 34 patients with moderate-severe OSA (AHI ≥ 15).
Results: Mean age was 71.4 ± 9.4 years (73 % male), and eGFR was 32.1 ± 12.3 mL/min/1.73 m2. DKD patients with moderate-severe OSA had a higher left atrial volume index (LAVI: 36.6 ± 13.9 vs. 28.1 ± 10.5 mL/m2, p < 0.01) left ventricular mass index (LVMI: 48.8 ± 11.7 vs. 41.8 ± 9.7 g/m2.7, p < 0.01) and right ventricular diameter (RVD: 34.1 ± 5.8 vs. 28.4 ± 4.4 mm, p < 0.001) than DKD patients without OSA. Left ventricular ejection fraction (LVEF) did not differ, but global longitudinal strain (GLS) was reduced (-15.1 ± 3.0 vs. -16.6 ± 2.8 %, p < 0.05). In multivariable linear regression analyses, moderate-severe OSA remained significantly associated with LAVI, LVMI, RVD, and GLS but not with LVEF.
Conclusions: Moderate-severe OSA is associated with cardiac hypertrophy and chamber dilatation, potentially contributing to cardiovascular risk in advanced DKD.
期刊介绍:
Diabetes Research and Clinical Practice is an international journal for health-care providers and clinically oriented researchers that publishes high-quality original research articles and expert reviews in diabetes and related areas. The role of the journal is to provide a venue for dissemination of knowledge and discussion of topics related to diabetes clinical research and patient care. Topics of focus include translational science, genetics, immunology, nutrition, psychosocial research, epidemiology, prevention, socio-economic research, complications, new treatments, technologies and therapy.
