Our expert says:
The simple answer to your question - whether angina or any other heart condition can be diagnosed before the event actually occurs - is yes. You are obviously referring to coronary disease, which usually is present in mild form, without symptoms, for many years before it actually causes trouble such as heart attacks. The difficulty is to identify and then treat the condition long before it causes trouble. The traditional way to do this is with an exercise ECG. However exercise ECG’s by their nature cannot identify mild narrowing.
A much better test is to look for evidence of hardening of the arteries with a special x-ray (a CT scan) called a coronary calcium score. If at the age of 48 you already have some coronary calcification then you need to take cholesterol lowering medication even though your cholesterol is “normal”.
My advice would be to see your doctor and ask him to request a coronary calcium score on your behalf. A cardiologist or I can then help you to interpret the result.
Best wishes, JT.
