Chest Pain: Imminent Heart Attack Misdiagnosis in ER

Imminent heart attack can be missed by ER doctor when it comes to your chest pain.
The ER doctor may misdiagnose your chest pain as GERD (gastroesophageal reflux disease). My mother went into the ER with chest pain and shortness of breath, and the ER doctor thought it was GERD after the second troponin test (like the first) came back normal.

He actually told my mother, “I don’t think you have a heart problem. This has a GI flavor to it.” GERD often causes chest pain. 

The ER doctor prescribed Prilosec, an indigestion drug. Less than 48 hours later, my mother was undergoing quintuple bypass surgery.

Warning: A negative troponin test only rules out that you just had a heart attack. It does not  --  I repeat  --  it does not rule out imminent heart attack! 

A negative troponin test only means you didn’t have a heart attack. It does not mean you won’t within the next 24 hours!

My sister is a medical doctor. She flipped when I told her the ER doctor diagnosed my mother’s chest pain and shortness of breath as GERD. 

“This happens all the time!” fumed my sister. “Chest pain is so often misdiagnosed as GERD and patients are sent home and then have a heart attack!”

My mother didn’t have the heart attack. Two days later she was back in the ER with chest pain, and this time, a different ER doctor recommended she be admitted because her troponin level was elevated – not enough to diagnose heart attack, but enough to concern the ER doctor. If you come in with chest pain complaints, you’ll get the troponin test.

She was supposed to get a stress test anyways, and realized that being admitted meant she’d get the stress test a lot sooner than going through her primary care doctor. 

There was no further chest pain during her evening and overnight hospital stay, and even next day, no chest pain.

An echocardiogram was performed first (the next day) to see if it was safe to have a stress test. The echocardiogram came back “abnormal,” and the cardiologist recommended the invasive catheter angiogram. 

“It’s unsafe to send you home,” the internal medicine doctor told her after she insisted she wanted to just go home.

All along, I had felt funny about that first ER diagnosis of GERD. That first visit wasn’t just for chest pain and shortness of breath, but my mother had vomited that morning; chest pain, shortness of breath and vomiting can mean an imminent heart attack.

However, the first ER doctor was too sure that the chest pain, shortness of breath and vomiting meant GERD.

In my layman’s, common-sense-based opinion, he should have explained, “The negative troponin means you did not have a heart attack. We did not give you a diagnostic test for GERD, and this may very well be GERD, but we also did not give you any tests to rule out severe heart disease, either. Though your symptoms sound like GERD, they also sound like extensive coronary artery blockage. I can’t send you home with a diagnosis of GERD. I am going to send you home with a diagnosis that you did not have a heart attack. But I can’t say that you won’t have a heart attack in the next 24 hours.”

The catheter angiogram revealed extensive coronary artery blockage, and the bypass surgery was begun only a few hours later; that’s how emergent the situation was.

Prior to surgery, I had asked the cardiothoracic surgeon, cardiologist and internal medicine doctor, “You mean, if my mother goes home without this surgery, she might have a fatal heart attack within a week?” All three simultaneously said yes.

Warning: If you have chest pain and the ER doctor diagnoses you with GERD, get a CT angiogram! A study by the University of Pennsylvania School of Medicine showed that a CT angiogram is an invaluable tool for screening for severe coronary artery disease.

Don’t just go home like my mother did and think that chest pain that awakens you at 5 am (as with my mother) can be explained by mere indigestion.
