Ergonovine provocation was more sensitive than exercise or cold pressor testing; leaves open its role in variant angina diagnosis pending prospective studies.
Does ergonovine testing have higher sensitivity than exercise or cold pressor testing in provoking attacks of variant angina in patients with active disease?
Ergonovine testing is highly sensitive for provoking variant angina, whereas the cold pressor test has too low a sensitivity to be clinically valuable.
Waters et al. (1983) studied this question.
