My grandfather had the hiccups for 3 days before he had heart attack and passed away.  My 92 year old father has heart disease, and was recently released from the hospital.  He has had the hiccups for 2 days.  Is there a connection between hiccups and heart attacks?
Hello, Yes, of recent there have been a few case reports of Hiccups presenting as a sign of Myocardial Infarction (Heart Attack)Now for your Understanding let me tell you that hiccups are generally benign and can be broadly categorized as Recurrent Hiccups which last up-to 48 hours, Persistent Hiccups that Last for more than 48 hours but less than a month, Intractable Hiccups which last for more than 2 months.However, the exact mechanism of the correlation between hiccups and heart attack is still not well established. But patients having persistent hiccups should not be overlooked and should be screened for signs of myocardial ischemia.
