Obstructive sleep apnea contributes to coronary artery disease development and poor prognosis

Area of Science:

• Cardiology and Sleep Medicine
• Investigating the intricate relationship between sleep disorders and cardiovascular health.

Background:

• Coronary heart disease (CHD) remains a leading cause of mortality worldwide.
• Obstructive sleep apnea (OSA) is an increasingly recognized comorbidity with potential cardiovascular implications.
• Understanding the interplay between OSA and CHD is crucial for effective patient management.

Purpose of the Study:

• To determine the correlation between obstructive sleep apnea (OSA) and the incidence of coronary heart disease (CHD).
• To evaluate the impact of OSA severity on short-term outcomes in patients diagnosed with CHD.
• To identify key risk factors associated with CHD development.

Main Methods:

• Retrospective analysis of 78 CHD patients and 78 healthy controls.
• Comparison of OSA prevalence and baseline characteristics between groups.
• Subgroup analysis of CHD patients based on OSA severity (mild-to-moderate vs. severe) and follow-up for adverse cardiovascular events.

Main Results:

• The CHD group exhibited significantly higher incidences of OSA, hypertension, dyslipidemia, and diabetes compared to controls.
• Multivariate analysis confirmed OSA, hypertension, dyslipidemia, and diabetes as independent risk factors for CHD.
• Severe OSA patients showed elevated peripheral hemoglobin and IL-6 levels, increased coagulation dysfunction, and higher diabetes mellitus rates compared to mild-to-moderate OSA patients.

Conclusions:

• Obstructive sleep apnea (OSA) is strongly associated with the occurrence of coronary heart disease (CHD).
• A predictive model incorporating OSA and other baseline data demonstrates favorable efficacy in predicting CHD.
• The severity of OSA significantly influences the prognosis and short-term outcomes of patients with coronary heart disease.
