One of the earliest distinguishing symptoms between a heartburn and a cardiac arrest is that heart attack is often accompanied with breathlessness.

‘Heartburn is a symptom and is not related to the heart in anyway while heart attack is an ailment that causes breathlessness.’

"Heartburn does not cause symptoms such as breathlessness. On the other hand, a cardiac arrest does not cause bloating or belching, which are common in case of a heartburn," says Dr Piyush Jain, Head Preventive Cardiology, Fortis Escorts institute. 




Jain says the uneasiness from heartburn can be treated with drugs that regulate the acid levels in stomach. Heartburn and heart attacks, though having striking similarities in symptoms, have absolutely nothing in common when spoken about in medical terms.
"We should know that heartburn is a symptom and not a disease itself and more importantly, though the pain is located in the chest, it is not related to heart in any way. It is basically an acid reflux from stomach to the food pipe."A heart attack takes place when there is a loss of blood supply to part of the heart muscle," says Jain.
As far as medical diagnosis is concerned, Dr Devi Prasad Shetty, cardiac surgeon and Founder of Naryana Health, a Bangalore based health speciality chain, the two can be easily distinguished in seconds with a "simple test" called 'CT angio'. "CT angio is a phenomenal test. It takes five seconds for the doctor to know about the problem with this. It's like taking a photo. Morever, it can predict heart attacks even 5-10 years ahead," says Shetty
