[Heart failure].
It seems that the causes of the insomnia are dyspnea and an orthopnea in the heart failure patient. But, only such a fit is not the cause of the insomnia because it complains about the insomnia even if heart failure is slight. An obstructive sleep apnea (OSA) is the risk of the heart failure. A heart failure patient often complicates a central sleep apnea (CSA) and a Cheyne-Stokes respiration (CSR), and has much sleep fragmentation and difficulty maintaining sleep. And sleep disorders are sometimes started by the medications such as the cardiovascular system agent thing; beta blocker and the statins. Sleep disorders represent a major challenge in terms of differential diagnosis in heart failure patients. This is particularly relevant to insomnia and sleep disordered breathing (SDB) such as OSA, CSA and CSR. Thus, expending the knowledge on both insomnia and SDB may contribute to improve medical quality among physician.
