    ### Instruction:
    What is the outlook for Sleep Apnea ?
    ### Response:
    Untreated, sleep apnea can be life threatening. Excessive daytime sleepiness can cause people to fall asleep at inappropriate times, such as while driving. Sleep apnea also appears to put individuals at risk for stroke and transient ischemic attacks (TIAs, also known as mini-strokes), and is associated with coronary heart disease, heart failure, irregular heartbeat, heart attack, and high blood pressure.
