Population

Patients with sleep apnea (context for chronic intermittent hypoxia)

Design

Preclinical

Authors

No immediate clinical implications for sleep apnea; leaves open HIF-1/Angptl4 as a research target in atherosclerosis.

This research aims to investigate the role of chronic intermittent hypoxia in activating angiopoietin-like 4 and its contribution to atherosclerosis.
Examined the increase in adipose Angptl4 mediated by HIF-1
Analyzed the subsequent inactivation of lipoprotein lipase
Considered the implications for patients with sleep apnea
Found a significant increase in adipose Angptl4 levels due to HIF-1 activation
Demonstrated a correlation with lipoprotein lipase inactivation, linking it to atherosclerosis

Population

Patients with sleep apnea (context for chronic intermittent hypoxia)

Intervention

Chronic intermittent hypoxia

Outcome

Atherosclerosis

Identifies a potential mechanism (HIF-1/Angptl4 pathway) by which chronic intermittent hypoxia in sleep apnea contributes to atherosclerosis.

Drager et al. (2013) studied this question.
