Does not support routine CPT/HVT provocation in severe angina; leaves open whether detected vasospasm warrants targeted therapy.
What is the prevalence of vasospastic ischaemia induced by the cold pressor test or hyperventilation in patients with severe angina?
Coronary artery spasm provocation using CPT and HVT identifies vasospastic ischaemia in nearly a quarter of patients with severe angina, independent of increased myocardial oxygen demand.
Rasmussen et al. (1984) studied this question.
