Diagnostic and Prognostic Value of Ergonovine Echocardiography for Noninvasive Diagnosis of Coronary Vasospasm
2020, JACC: Cardiovascular ImagingDiagnosis of vasospastic angina: Comparison of hyperventilation and cold-pressor stress echocardiography, hyperventilation and cold-pressor stress coronary angiography, and coronary angiography with intracoronary injection of acetylcholine
2007, International Journal of CardiologyCitation Excerpt :Indeed, stress echocardiography reportedly provides more accurate diagnosis of myocardial ischemia than exercise ECG [24], though most previous studies only evaluated its usefulness for diagnosing organic coronary stenosis. Still, Distante et al. [25,26] and Rovai et al. [27] both reported that left ventricular wall motion abnormalities could be detected before the appearance of significant ST–T changes or chest pain in patients with coronary spasm, and Fujii et al. [28] reported that 30% of occurrences of multivessel spasm could be diagnosed by hyperventilation stress echocardiography. What's more Song et al. [29] intravenously administered ergonovine to 218 patients with suspected vasospastic angina to evaluate wall motion using 2-dimensional echocardiography and reported that vasospastic angina could be diagnosed with 93% sensitivity and 91% specificity.
Diagnosis of vasospastic angina by hyperventilation and cold-pressor stress echocardiography: Comparison to <sup>123</sup>I-MIBG myocardial scintigraphy
2002, Journal of the American Society of EchocardiographyCitation Excerpt :Sueda et al23 used hyperventilation alone, hyperventilation and cold-pressor stress, and hyperventilation and treadmill exercise to induce coronary spasm in 24 patients with suspected vasospastic angina and reported that coronary spasm was induced by hyperventilation and cold-pressor stress in only 2 of 24 (8%) patients, and the combination of hyperventilation and treadmill exercise showed the highest diagnostic accuracy (sensitivity: 67%). Distante et al,24 Rovai et al,25 and Yamamoto et al8 reported that they could detect coronary spasm earlier by 2D echocardiography despite the absence of ST-segment changes or chest pain. Fujii et al26 reported that 30% of multivessel spasm could be diagnosed by hyperventilation stress echocardiography.
Efficiency of ergonovine echocardiography in detecting angiographically assessed coronary vasospasm
2001, American Journal of CardiologyHyperventilation and cold-pressor stress echocardiography for noninvasive diagnosis of coronary artery spasm
2001, Journal of the American Society of EchocardiographyCitation Excerpt :When Shimizu et al12 combined hyperventilation with cold-pressor stress, they reported that the sensitivity of electrocardiography for diagnosing variant angina was increased to 82%. Distante et al,22,23 Rovai et al,24 and Yamamoto et al25 reported that they could detect coronary spasm earlier by monitoring left ventricular wall motion despite the absence of significant ST-T changes or chest pain. Song et al26,27 suggested that bedside, intravenously administered ergonovine with 2D echocardiography could be safely used to detect coronary spasm.
