Abstract
Answer C.
For patients in whom stable angina cannot be diagnosed or excluded by clinical assessment alone, estimate the likelihood of coronary artery disease (CAD).
If the estimated likelihood of CAD is 61–90%, offer invasive coronary angiography as the first-line diagnostic investigation (if appropriate) If the estimated likelihood of CAD is 30–60%, offer functional imaging as the first-line diagnostic investigation If the estimated likelihood of CAD is 10–29%, offer CT calcium scoring as the first-line diagnostic investigation
This guidance was published in March 2010, and most local rapid access chest pain clinics still currently use an exercise electrocardiogram (ECG) as the first-line investigation of choice for the diagnosis of stable angina.
NICE Clinical guideline 95: chest pain of recent onset.
