Abstract

Background: Dobutamine stress echocardiography is used to differentiate between stunning and hibernating myocardium in individuals with left ventricular failure and to detect coronary artery stenosis noninvasively. Objective: Find out how adding nitroglycerin to low-dose dobutamine stress echocardiography affects the viability of the heart in patients whose hearts do not show viability to dobutamine alone. Patients and methods: Eighty adult patients who had previously experienced a myocardial infarction and were seen in the cardiology department at Al-Azhar University Hospitals between September 2022 and October 2023 participated in a prospective interventional trial. Results: Compared to the LDDE + NTG Success group (1.68 ± 0.19), the WMSI was considerably higher in the Failure group (1.94 ± 0.14) (P= 0.000). However, there was no discernible difference in resting and LDDE between the two groups under study (P>0.05). Conclusion: Dobutamine-NTG echocardiography is a safer and more sensitive diagnostic technique for determining the presence of a viable myocardium compared to dobutamine echocardiography.
