Every week, about a third of the people who walk into our chest pain clinic are convinced they're having a heart attack. Most aren't. But some who wave it off are. Here's how cardiologists actually think about chest pain - so you know when to relax, and when to move fast.

The pain that usually isn't your heart

Pain that changes when you press on the spot, twist your torso, or take a deep breath is usually coming from the chest wall - muscles, ribs, cartilage. Burning that climbs from the stomach upward after meals points to acid reflux. Sharp, second-long stabs that come and go are rarely cardiac either.

The common thread: cardiac pain doesn't usually respond to position, pressure or antacids, and it rarely lasts less than a minute or more than a fortnight without other signs.

Call 1800 309 9999 now if chest pain comes with sweating, breathlessness, nausea, or pain spreading to your arm, jaw or back. Don't finish this article first.

"Cardiac pain doesn't care how you sit, what you press, or what you ate. If your pain does - that's a clue."

Dr. Anitha Rao, in the chest pain clinic

The pain that might be

Treat it as cardiac until proven otherwise if the pain is:

Pressure or heaviness rather than a sharp stabTriggered by climbing stairs or hurrying, eased by restAccompanied by sweating, nausea or breathlessnessSpreading to the arm, jaw, neck or back

Heaviness, tightness or pressure - "like someone sitting on my chest" - that appears with exertion and eases with rest is the classic pattern of angina. So is breathlessness that's new, or unusual fatigue doing things that were easy last month. Diabetics and women often get subtler versions: jaw ache, indigestion-like discomfort, or just profound tiredness.

What we do when you can't tell

That's what the chest pain clinic is for. An ECG and troponin blood test rule a heart attack in or out within an hour. If doubt remains, a treadmill test or CT coronary angiography settles it - usually the same day. The worst strategy is deciding at home with Google at 2 AM.

1Hour one: ECG and troponin - a heart attack is ruled in or out.

2Same morning: if doubt remains, a treadmill test or CT angiography.

3Before you leave: a clear answer and a plan - even if the plan is "go home, it's your rib."

The takeaway

Positional, pressable, or fleeting pain: probably not your heart. Pressure with exertion, sweating or breathlessness: assume it is, and come in. When in doubt, an hour in the chest pain clinic beats a week of worrying.
