International standardization of diagnostic criteria for vasospastic angina.

[Usefulness of washout rate analysis in adenosine triphosphate-stress thallium-201 myocardial scintigraphy in patients with vasospastic angina].

OBJECTIVES This study evaluated the usefulness of washout rate analysis in adenosine triphosphate(ATP) stress thallium-201 scintigraphy for the diagnosis of vasospastic angina. METHODS This study included 76 patients with vasospastic angina and 18 normal controls undergoing coronary arteriography. If significant coronary artery stenosis (> or = 50%) was pointed out, the subject was excluded f...

Relation of basal coronary tone and vasospastic activity in patients with variant angina.

OBJECTIVE To examine the vasoconstrictor response to ergonovine and the vasodilator response to isosorbide dinitrate in spastic and non-spastic coronary segments from 31 patients undergoing serial angiographic follow up of variant angina. METHODS Coronary angiograms and ergonovine provocation tests were repeated at an interval of 45 (SD 15) months apart. While all 31 patients showed a positiv...

Vasospastic angina behaves differently in men and women.

Ergonovine test in angina with normal coronary arteries. Is it worth doing it?

BACKGROUND Patients with angina and normal coronary arteries are often misdiagnosed with having non-cardiac pain. Although vasospasm is a well-known entity, spasm provocation is not routinely done in the majority of hospitals at present. MATERIALS AND METHODS One hundred and sixty two consecutive patients with thoracic pain and normal coronary arteries were retrospectively studied. The charac...

Coronary Vasospastic Angina: Assessment by Multidetector CT Coronary Angiography

OBJECTIVE We aimed to describe the imaging findings of multidetector CT coronary angiography (MDCTA) in cases of vasospastic angina (VA) and to determine the accuracy of MDCTA in the identification of VA as compared with invasive coronary angiography with an ergonovine provocation test (CAG with an EG test). MATERIALS AND METHODS Fifty-three patients with clinically suspected VA were enrolled...
