Researchers from Brigham and Women's Hospital found that sex-specific differences exist in the relationship between obstructive sleep apnea and cardiovascular disease and that, in women, sleep apnea was associated with higher blood levels of troponin (hs-TnT), a marker that provides information on early evidence of heart injury.
For the study, researchers collected and analyzed data from more than 1,600 people who were free of heart disease. At the beginning of the study, when participants were an average age of approximately 63 years, 23 percent of men and 10 percent of women had undiagnosed moderate to severe sleep apnea.

September 9, 2015 — Researchers at Thomas Jefferson University showed that a simple questionnaire, evaluation and pulse-oximetry monitoring can lead to early detection of sleep apnea in patients hospitalized for congestive heart failure (CHF). This study adds to a growing body of research suggesting a connection between sleep disordered breathing and heart failure. Consecutive patients admitted for congestive heart failure at Thomas Jefferson University Hospital were screened by respiratory therapists using the STOP-BANG Questionnaire (Snoring, Tiredness during daytime, Observed apnea, high blood Pressure – Body mass index greater than 35, Age greater than 50 years, Neck circumference greater than 40 centimeters and Male gender). If the patient screened positive, they received a formal sleep consult during their hospital stay and underwent high-resolution pulse-oximetry testing, which assessed the patient’s oxygen desaturation index (ODI).

Studies have reported that between 11% and 37% of heart failure patients also have sleep apnea. High blood pressure, which is associated with sleep apnea, is a major cause of later heart failure. Sleep apnea may directly contribute to the progression of heart failure by reducing oxygen levels and causing abnormal changes in blood pressure and heart rate that add to the burden of the failing heart.
In any case, obstructive sleep apnea can affect breathing functions in a way that may be particularly harmful for patients with existing congestive heart failure. Over a 14 year follow up, 46 percent of men and 32 percent of women experienced a significant adverse cardiac event, death, or had an enlarged heart, HealthDay reported.

The results were published in the Journal of American College of Cardiology: Heart Failure.


Of those who followed up with the recommended polysomnography (n=68), 94 percent (n=64) were diagnosed with sleep disordered breathing. One small 1998 study reported a drop in blood flow in the brain during episodes of obstructive hypopnea (slow and shallow breathing associated with snoring). And there is an increased mortality associated with Cheyne-Stokes respiration in patients with congestive heart failure. A 1999 study, in fact, indicated that sleep apnea is associated with poorer survival in patients with heart failure.
Women with moderate to severe sleep apnea were more than 30 percent likely to experience these adverse heart problems compared to women without sleep apnea.
Yet early recognition and treatment of this disorder in patients with congestive heart failure has been shown to improve ejection fraction, acute heart failure and may even reduce readmissions and mortality,” Sharma continued. Researchers hypothesized that dips in oxygen levels throughout the night were a sign of obstructive sleep apnea. Some evidence suggests that treating sleep apnea with continuous positive airway pressure (CPAP) may improve heart function in these patients. This relationship was not statistically significant in men, suggesting that factors such as age, obesity, hypertension and diabetes explained most of the observed heart disease risk in the men studied.
Such declines in blood flow did not appear to occur with obstructive or central sleep apnea, however.
