Sleep is an active, energizing and blissful activity, which everybody enjoys. Diseases affecting any system of the body can alter sleep and sleep disorders can lead to problems in multiple systems of the body. Much research is going on in the field of sleep medicine and its effects on health. The association between sleep disorders and cardiovascular diseases is well known. Obstructive Sleep Apnea (OSA) is known to cause ischemic heart disease and other related cardiovascular diseases. Severe heart diseases like congestive heart failure also are known to produce sleep disordered breathing. Relationship of cardiovascular diseases to certain phases of the sleep cycles has also been reported. There is a definite need for physicians, cardiologists and sleep specialists to work together in this field of sleep disorders and cardiovascular diseases in order to improve detection and management of these conditions.
