This descriptive study describes the frequency and severity of sleep-related breathing disorders in men who are hemodynamically stable who have an acute cardiovascular illness and are hospitalized in a critical care unit. Sixty-four males, aged 55-79 years, with an acute cardiovascular illness, stable hemodynamics, and no ongoing chest pain or history of
sleep apnea
were studied for 1 night in the critical care unit using polysomnography. Forty-seven percent of the sample had an apnea-hypopnea index > or = 5, with events of both obstructive and central etiologies, including Cheyne-Stokes respiration. Oxygen desaturation to < or = 90% occurred in 61% of the sample. There were no episodes of chest pain, ventricular tachycardia, or heart block associated with apneic or hypopneic events; however, dysrhythmias, including sinus bradycardia,
supraventricular tachycardia
, and premature ventricular beats, were associated with apneic and hypopneic events.

Patients with obesity tend to have a higher incidence of hypertension, coronary artery disease, and
sleep apnea
, conditions that could potentially predispose to complications during transesophageal echocardiography (TEE). In addition, patients who are obese are more likely to have oxygen desaturation during upper gastrointestinal endoscopy. However, the safety of TEE in a large cohort of patients with obesity has not been reported. Thus, the safety of TEE in 341 patients who were obese (body mass index >/= 27.5 kg/m(2), mean 41.0 +/- 10.3) and in 323 control patients who were not obese was compared. Minor complications (ie, complications of a transient duration and requiring no or only simple intervention) occurred with equal frequency in the control and obese groups (16.5% vs 16.7%, P = not significant). Transient oxygen desaturation did not differ between the control versus obese group (2.5% vs 3.8%, P = not significant), but was more common (6.7%) in a subgroup (n = 150) of patients who were morbidly obese as compared with control patients (P <.05). Transient hypotension was observed in 3.5% of the obese group compared with 7.4% in the control group (P <.05). However, transient hypertension was noted in 10.6% of the patients who were obese compared with 6.5% in the control group (P =.072). A major complication occurred in 2 patients with obesity, one who required vasopressor medication for persistent hypotension and another needing pharmacologic rate control of atrial fibrillation. One patient in the control group had provoked
supraventricular tachycardia
and angina. No deaths occurred in either group. Subjective tolerance for the procedure was similar (P = not significant) in both groups with 84% of patients with obesity having good to excellent tolerance compared with 88% in that of the control group. Thus, TEE can be safely performed in patients who are obese.
