By mapping the changes to graded doses of dobutamine, DSE permits us to detect myocardial ischemia and to assess whether myocardial damage is reversible. As a result, this test can help predict which patients are likely to benefit from revascularization. DSE also allows us to determine a specific point at which evidence of ischemia begins. The test is highly accurate, safe, and comparatively inexpensive.</p>","PeriodicalId":80210,"journal":{"name":"The Journal of critical illness","volume":"9 7","pages":"702-8"},"PeriodicalIF":0.0,"publicationDate":"1994-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21019619","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
