Updated knowledge and practical implementations of stress echocardiography in ischemic and non-ischemic cardiac diseases: An expert consensus of the Working Group of Echocardiography of the Hellenic Society of Cardiology
2022, Hellenic Journal of CardiologyCitation Excerpt :Higher dobutamine infusion rates (up to 40 mcg/kg/min) may be applied for myocardial ischemia detection, after completion of the viability test (Fig. 1E). Withdrawal of beta-blockers is not mandatory before the test, but their presence may reduce the sensitivity of the method102. Alternatively, proceeding to high-dose dobutamine infusion may be effective and safe for b-blockers-treated patients.
Guidelines for Performance, Interpretation, and Application of Stress Echocardiography in Ischemic Heart Disease: From the American Society of Echocardiography
2020, Journal of the American Society of EchocardiographyCitation Excerpt :Continuous echocardiographic monitoring should be performed and in the optimal setting a physician interpreter is present to monitor for subtle and sometimes transient increases in function that may occur in hibernating myocardium.227 Discontinuation of beta-blockers is not essential but intermediate doses of dobutamine (15-20 μg/kg/min) may be needed to elicit a contractile response in the presence of beta-blocker therapy and the number of segments demonstrating contractile reserve may be reduced.232 For low and intermediate dose protocols, continuous monitoring of at least several ECG leads should be performed for detection of ischemic ST-segment abnormalities and arrhythmias.
Pulsed-wave tissue Doppler quantification of systolic and diastolic function of viable and nonviable myocardium in patients with ischemic cardiomyopathy
2004, American Heart JournalCitation Excerpt :In our hospital, β-blocker therapy is not routinely withheld before stress testing; we believe that this reflects daily clinical practice. Moreover, previous data indicate that β-blocker therapy may be continued during myocardial viability assessment in patients with ischemic cardiomyopathy.12 Recently, it has become clear that not only systolic dysfunction but also abnormalities in diastolic function play an important role in producing signs and symptoms of heart failure.13
