Apnea Treatment Gets Heart Back in Shape

Several studies have suggested that obstructive sleep apnea contributes to the development of left ventricular systolic and diastolic dysfunction and, possibly, heart failure. Note that this study indicates that moderate-to-severe sleep apnea can cause structural and functional changes in left ventricular function comparable to that seen in hypertension and, further, these abnormalities significantly improve following CPAP therapy.

The risk of death for patients with thrombosis was highest in the first year after the event, with a hazard ratio of 14.4 95% CI 7.1 to 29.2, according to Frits R. Rosendaal, MD, PhD, and colleagues from Leiden University in the Netherlands.But the risk remained elevated eight years later HR 3.8, 95% CI 0.5 to 30.8, the researchers reported in PLoS Medicine.

“Remarkably,” the mortality rate was five times higher among patients with malignancy and thrombosis than among those who had a malignancy without thrombosis (SMR 5.5, 95% CI 5 to 6.1), the researchers observed.
