How do I know if it is angina or a heart attack?
Angina settles with rest within a few minutes. A heart attack does not.
Chest pain lasting more than 15 minutes, occurring at rest, or coming with sweating and nausea is a 999 call — do not wait to see whether it passes.
My ECG was normal. Does that rule it out?
No, and this is important. A resting ECG is frequently normal in stable angina, because the heart is not under strain while you lie still.
A normal ECG plus a convincing exertional history still warrants investigation.
Can I still exercise?
Yes, and you should — within the limits you have been given. Exercise improves angina rather than threatening it, and cardiac rehabilitation improves survival.
Warm up gradually and use your GTN spray beforehand if a particular activity reliably provokes symptoms.
Why does my GTN spray give me a headache?
Because it widens blood vessels in the head as well as the heart. It is very common, it is not dangerous, and it usually eases with continued use.
It is not a reason to stop carrying it.
Can I take Viagra with my heart medication?
Not with nitrates — GTN spray, isosorbide, or poppers. That combination can be fatal.
Always tell the prescriber you use a nitrate, and never take a friend's tablet.
Do I have to take a statin if my cholesterol is normal?
In established coronary disease, yes — and the reason is not the number. Statins stabilise the plaque in the artery wall, which is what prevents the next event.
That benefit applies even at a normal cholesterol level, which is why the advice can seem counterintuitive.
Will I definitely need a stent?
No. Many people are managed well on medication alone, and in stable angina stenting mainly improves symptoms rather than survival.
That is a genuine trade-off worth discussing rather than assuming a procedure is inevitable.
Can I drive?
With stable angina, usually yes for a standard licence — but you must stop if symptoms come on at rest or while driving.
Bus and lorry licences are stricter and the DVLA must be informed. Check your own situation rather than relying on general advice.
Could this be stress or reflux instead?
It could — both are common causes of chest discomfort. But the safe order is to exclude the heart first.
Attributing exertional chest tightness to stress without assessment is the mistake that matters.
