Human: I've heard that snoring is a sign of a heart attack. Is this true? Assistant: 
No, snoring is not a sign of a heart attack. Snoring can be caused by a variety of medical conditions and is often associated with obstructive sleep apnea (OSA). OSA is an increasingly common condition in which the upper airway becomes blocked during sleep. This blockage causes breathing to become more shallow and noisy, resulting in snoring. However, there are many other factors that can cause snoring besides OSA, such as allergies, obesity, smoking, alcohol consumption, and medications. So snoring is not necessarily a sign of a heart attack.
