Invasive vs non-invasive treatment in acute coronary syndromes and prior bypass surgery.

Background: We evaluated the association between invasive and non-invasive management and hospital and 6-month outcomes in patients with a prior coronary artery bypass graft (CABG) who experienced an acute coronary syndrome.

Methods: Data were analysed from patients with a prior CABG who developed an acute coronary syndrome and were enrolled in the Global Registry of Acute Coronary Events. From 44,991 patients included in the study, 3853 fulfilled the inclusion criteria.

[Comparison between electrocardiographic test with dobutamine and exercise stress testing on coronary risk stratification].

The exercise testing is still the most common test used to stratify the patients's risk of new events following an acute myocardial infarction, but about 20 to 40% of the patients can not perform it appropriately. Since the electrocardiographic test with dobutamine has proved to be easy and safe, our aim was to evaluate its capacity to predict the results of the exercise testing on patients after an acute myocardial infarction. A total of 210 patients (average of age 60.
