Risk for Cardiovascular Disease and One-Year Mortality in Patients With Chronic Obstructive Pulmonary Disease and Obstructive Sleep Apnea Syndrome Overlap Syndrome

Abstract: Background: Patients with chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSAS) overlap syndrome (OS) are thought to be at increased risk for cardiovascular diseases.Objective: To evaluate the burden of cardiovascular diseases and long-term outcomes in patients with OS.Methods: This was a retrospective cohort study. The prevalence of cardiovascular diseases and 1-year mortality were compared among patients diagnosed with OS (OS group), COPD alone (COPD group) and OSAS alone (OSAS grou… Show more

“…In the literature, there are many arguments in support of the association between obstructive sleep apnoea syndrome (OSAS) and cardiovascular disease (CVD). Indeed, the prevalence of OSAS may reach 70.0% in individuals with CVD, and the incidence of CVD is high in apnoeic individuals [ 1 , 2 ]. In addition, OSAS is associated with a negative impact on cardiovascular prognosis, both in the general population and in individuals with CVD [ 3 , 4 , 5 ].…”

“…The retrospective cohort study by Tang et al [ 8 ] in 6554 patients (OS 192) revealed that individuals with OS had worsening baseline features and a higher prevalence of cardiovascular diseases, such as heart failure, compared to individuals with COPD or OSAS only (adjusted hazard ratio (aHR): 3.067 (1.521–6.185); p = 0.002) and PH (aHR: 2.006 (1.005–4.004); p = 0.048). Among 43 heart failure patients, 28 had OS, 14 had COPD only, and 1 had OSAS.…”

“…Intermittent hypoxia associated with OSAS is also associated with the onset and progression of various other diseases [ 20 ]. Moreover, untreated OSAS carries the possible risk of serious complications and mortality [ 21 , 22 ]. Oxidative stress caused by hypoxia affects cellular metabolism and leads to endothelial cell dysfunction, which are the main pathological mechanisms underlying the progression of cardiovascular and cerebrovascular disease in patients with OSAS [ 23 ].…”
