چکیده

The authors describe a case of a critically ill patient presenting after motor vehicle trauma complicated by anterior myocardial infarction and cardiogenic shock. Assessment of myocardial viability in the territory of a critically stenosed left anterior descending artery (LAD) was necessary to determine the optimal management strategy. Bedside dobutamine stress echocardiography (DSE) demonstrated viability in the LAD territory and the patient underwent uncomplicated single-vessel bypass surgery with subsequent improvement in left-ventricular function. This case illustrates the utility of bedside DSE to assess myocardial viability in patients for whom other non-invasive modalities are not feasible.

Coronary Artery Spasm During Dobutamine Stress Echocardiography: A Case Report

Dobutamine stress echocardiography (DSE) has been widely used as a diagnostic and prognostic modality in the management of stress. DSE is associated with limited complications and adverse effects on the health of patients. In this case report, we described a 42-year-old female patient with dobutamine-induced coronary artery spasm with history of exertional dyspnea, which had deteriorated recent...

Dobutamine-Induced Strain and Strain Rate Predict Viability Following Fibrinolytic Therapy in Patients with ST-Elevation Myocardial Infarction

BACKGROUND Low-dose dobutamine stress echocardiography is increasingly used for identifying myocardial viability. AIM We explored whether dobutamine-induced strain (S) and strain rate (SR) can identify myocardial viability following fibrinolytic therapy for ST-segment-elevation myocardial infarction (STEMI), taking (99m)Tc-sestamibi scintigraphy as the "gold standard" for diagnosis. METHODS...

tolic function will improve after coronary revascularization (viability testing) [3]. In general, stress CMR is frequently performed with one of two protocols. The more commonly used protocol is myocardial perfusion imaging, which involves intravenous administration of a vasodilator (i.e., adenosine). Stress perfusion CMR allows the evaluation of resting LV contraction as well as detection of m...

Automated assessment of myocardial viability after acute myocardial infarction by global longitudinal peak strain on low-dose dobutamine stress echocardiography.

BACKGROUND Low-dose dobutamine stress echocardiography (DSE) assesses myocardial viability at the early stage of acute myocardial infarction (AMI), but its assessment is subjective and variable. Automated function image (AFI) determines global longitudinal peak strain (GLPS) based on tissue tracking technique. The ability of GLPS obtained by AFI during dobutamine stress to assess myocardial via...
