Pharmacological Stress Echocardiography at Dobutamine in the Search of Ischemia: Epidemiological, Clinical and Tolerance Profile about 270 Patients
Downloads
INTRODUCTION: Stress echocardiography is considered today as a technique in the non-invasive assessment of coronary artery disease. It can detect anomalies in left ventricular segmental dynamics secondary to the ischemic process with excellent precision. The objective of our study is to determine the epidemiological, clinical, electrical and angiographic profile of patients admitted to our training for exploration and screening of coronary pathology on dobutamine stress echocardiography.
MATERIALS AND METHODS: This is a retrospective study carried out over a period of 2 years between January 2018 and December 2019 on 270 patients admitted to the service of non-invasive explorations of cardiology B of the Rabat University Hospital for pharmacological stress echocardiography at dobutamine for ischemia or study combined with ischemia and viability research.
RESULTS: The average age of our patients was 61.5. A female predominance was noted, the most common risk factor is high blood pressure, 31.5% were asymptomatic. On examination, 69% achieved 100% of theoretical maximum cardiac frequency and only 13% returned positive. The examination is often well tolerated in 89%. The artery affected by ischemia is often that of the anterior ventricular with a percentage of 46.7%. CONCLUSION: Stress echocardiography is a valid method in the non-invasive assessment of coronary artery disease, its tolerance is good and its safety is satisfactory. This study reflects the experience of the cardiology B department. It was able to reassess the diagnostic value of this method and invites to conduct prospective studies for a better approach of its prognostic value.
