Abstract/OtherAbstract:

Atrial pacing was carried out within 5 days of an uncomplicated acute myocardial infarction (AMI) in 28 patients to detect the existence of a menaced area. A positive pacing response (at least 1.0 mm of ST-segment shift) was observed in 23 patients (82%, group I), whereas pacing results were negative in 5 (18%, group II). Pacing-induced electrocardiographic changes involved the leads affected by AMI in patients with transmural necrosis. A well-defined thallium-201 redistribution, mostly localized near or within the AMI site, was present in 10 patients from group I (43%), in 1 from group II (20%), and in 1 of 12 comparable patients (8%) in whom pacing was not performed. During pacing, abnormal lactate metabolism was observed in 11 of 17 patients from group I (65%) and in 0 of 5 from group II (0%). A 90% or greater coronary stenosis of at least 1 artery was found in 19 of 23 patients from group I (83%) and in 1 of 5 from group II (20%); 2- to 3-vessel disease (more than 70% diameter stenosis) was present in 14 patients from group I (61%) and 1 from group II (20%). During a 15-month follow-up (range 9 to 25), effort angina developed in 9 patients from group I (39%) and in none from group II. No deaths or reinfarctions occurred in either group. Thus, very early after a first AMI, most patients have a jeopardized periinfarction area that is usually associated with a critical coronary stenosis and that heralds effort angina in a significant proportion of them. |
