We report the usefulness of 2-dimensional echocardiography during the cold-pressor test immediately after hyperventilation for noninvasive diagnosis of coronary vasospasm in 43 patients with suspected vasospastic angina. The stress test consisted of hyperventilation for 6 minutes, followed by cold w...
