Exercise-electrocardiography and/or pharmacological stress echocardiography for non-invasive risk stratification early after uncomplicated myocardial infarction. A prospective international large scale multicentre study.

Aims: The aim of the present study was to assess the relative prognostic value of clinical variables, the exercise electrocardiography test and the pharmacological stress echocardiography test either with dipyridamole or dobutamine early after a first uncomplicated acute myocardial infarction in a large, multicentre, prospective study.

Methods And Results: Seven hundred and fifty-nine in-hospital patients (age=56+/-10 years) with a recent and first clinical uncomplicated myocardial infarction, with baseline echocardiographic findings of satisfactory quality, an interpretable ECG and able to exercise underwent a resting 2D echocardiogram, a pharmacological stress test with either dipyridamole or dobutamine and an exercise electrocardiography test at a mean of 10 days from the infarction; they were followed-up for a median of 10 months. During the follow-up, there were 13 deaths, 23 non-fatal myocardial infarctions and 59 re-hospitalizations for unstable angina.

Value of pharmacologic stress echocardiography in risk stratification of patients with single-vessel disease: a report from the Echo-Persantine and Echo-Dobutamine International Cooperative Studies.

Objectives: This study sought to verify the effectiveness of pharmacologic stress echocardiography in risk stratification of patients with single-vessel disease.

Background: Noninvasive prognostic assessment of single-vessel disease is an unresolved issue to date.

Methods: The study evaluated prospectively collected data from 754 patients with angiographic single-vessel disease who underwent either dipyridamole (n = 576) or dobutamine (n = 178) stress echocardiography.

Role of stress echocardiography in risk stratification early after an acute myocardial infarction. EPIC (Echo Persantin International Cooperative) and EDIC (Echo Dobutamine International Cooperative) Study Groups.

Resting and stress echocardiography is a 'one-stop shop', which enables a wide range of information to be collected on resting function, myocardial viability, and induced ischaemia, all of which are useful for prognostic stratification. Large scale, multicentre, prospectively collected data show the prognostic failure of resting function and inducible ischaemia, both independently and combined, which are especially effective in predicting cardiac death. The GISSI data show that the increment of risk as a result of reduction in ventricular function has a hyperbolic trend, with a relatively moderate increase in mortality for ejection fraction values between 50 and 30%, but with marked increases below 30%.

The relative value of exercise-electrocardiography and dipyridamole stress echocardiography for risk stratification early after uncomplicated myocardial infarction. The EPIC (Echo Persantine International Cooperative) Study Group.

Background: Rational prognostic algorithm should be developed considering the logical progression of the information as it becomes available to the physician, with clinical data first, ECG data second and stress imaging data last. The aim of the present study was to assess in a clinically realistic fashion the relative prognostic value of exercise electrocardiography test (EET) and dipyridamole-echocardiography test (DET) early after first acute uncomplicated myocardial infarction.

Methods And Results: Five hundred and forty-seven in-hospital patients (age = 56 +/- 9 years) with recent clinically uncomplicated first myocardial infarction, baseline echocardiographic findings of satisfactory quality, interpretable ECG and capability to exercise underwent a resting 2D echocardiogram, a DET and an EET at a mean of 10 days from the infarction and were followed up for 16.

Does stress echocardiography predict the site of future myocardial infarction? A large-scale multicenter study. EPIC (Echo Persantine International Cooperative) and EDIC (Echo Dobutamine International Cooperative) study groups.

Objectives: We sought to assess whether the site of future myocardial infarction can be predicted on the basis of induced dyssynergy ("area at risk") recognized by stress echocardiography.

Background: The severity and extent of stress-induced dyssynergy are strong predictors of subsequent major cardiac events. However, high grade stenotic lesions are not strictly associated with the site of future coronary occlusions.
