[Exercise two-dimensional echocardiography in recent myocardial infarction. Is it useful in the detection of multivessel disease?].

Exercise two-dimensional echocardiography (2D-ECHO) can be used to detect coronary artery disease in patients (pts) by the development of stress-induced transient asynergy in areas without wall motion abnormalities when at rest. The aim of the study is to verify the accuracy of exercise 2D-ECHO in the identification of high risk pts with multivessel disease after the first acute myocardial infarction (AMI). Technically adequate 2D-ECHO examinations were obtained in 21 of 28 (75%) consecutive patients after acute myocardial infarction.

A reappraisal of the factors affecting early patency of aortocoronary saphenous vein bypass grafts. Current experience with extensive revascularization employing sequential grafting techniques.

A number of factors potentially influencing the patency rates of aortocoronary bypass grafts were investigated in a consecutive series of 50 patients by control angiography at 28 +/- 26 days and by univariate and multivariate analysis of a selected set of clinical, surgical and angiographic predictors. There were 234 anastomoses in this series, a mean of 4.7 per patient (range 1 to 9), 215 of which were connected to sequential vein grafts.

[Problems appearing after pharmacologic thrombolysis in acute myocardial infarct].

Pharmacologic myocardial reperfusion is a new strategy in the treatment of acute myocardial infarction, but its widespread use has raised several problems which are still unsolved. The time limit from the onset of ischemic pain until the beginning of thrombolysis is undefined yet. Experimental and clinical observations set this time within three hours.

[Pharmacologic myocardial revascularization in acute infarct. Experience with 52 cases].

Coronary thrombosis is frequently demonstrated in the early hours of acute myocardial infarction. Local infusion of thrombolytic agents has been proposed in order to dissolve intracoronary thrombi and to restore myocardial perfusion. We report our initial experience in 52 patients.
