Diagnostic and Prognostic Value of Ergonovine Echocardiography for Noninvasive Diagnosis of Coronary Vasospasm
2020, JACC: Cardiovascular ImagingCitation Excerpt :Positive criteria for the test included the appearance of transient ST-segment elevation or depression >0.1 mV at 0.08 s after the J point (ECG criteria), or reversible RWMAs shown on 2-dimensional echocardiography (echocardiographic criteria) (Figures 2 and 3). The criteria for terminating the test were as follows (16,18): a positive response according to the ECG or echocardiographic criteria, a total cumulative dose of 350-μg ergonovine, or development of significant arrhythmia or changes in vital signs (systolic blood pressure >200 mm Hg or <90 mm Hg). An intravenous bolus injection of nitroglycerin (0.25 mg), and sublingual nitroglycerin (0.6 mg), were given as soon as a positive response was detected or at the end of a test in the case of a negative response.
Diagnosis 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.
Stress echocardiography: A historical perspective
2003, American Journal of MedicineCitation Excerpt :In the first edition of Braunwald’s textbook (11), there were 60 pages about nuclear cardiology and none about stress echocardiography, which was still experimental. In the 2001 edition, nuclear cardiology is discussed for more than 50 pages, with less than one page on stress echocardiography (12), which in the meantime has completed the full circle of scientific validation from initial feasibility (7–9) to large-scale multicenter studies involving thousands of patients (13–15). Nuclear cardiology is the time-honored offspring of the marriage between nuclear technology and coronary physiology.
Hyperventilation 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.
