Abstract

The aim of the present study was to evaluate the influence of right ventricular involvement on the magnitude of precordial ST segment depression during inferior acute myocardial infarction. For this reason 61 patients (55 M, 6 F; mean age 53 years--range 38-73 years) admitted in our CCU for inferior acute myocardial infarction were studied by coronary angiography within 3-5 days from the onset of symptoms. The angiography showed either occlusion or critical coronary stenosis ranging as follows: on right coronary artery proximal (Group 1) to the first branch for right ventricle in 22 patients, on right coronary artery distal to the first branch for right ventricle in 25 patients (Group 2) and on circumflex artery (Group 3) in 14 patients. No difference in LAD disease were noted between the 3 groups. Using myocardial scintigraphy (Tc-99m- pyrophosphate) we confirmed the presence or the absence of right ventricular involvement in the 3 groups. In the 3 groups the magnitude of ST segment depression in V2, selected as representative left-sided precordial lead, ranged as follows: Group 1: -0.25 +/- 1.34 mm; Group 2: -1.64 +/- 1.80 mm; Group 3: -2.00 +/- 1.97 mm. In patients with right ventricular involvement (Group 1) there was a statistically significant reduction of precordial ST segment depression either in comparison to Group 2 (p less than 0.01) or to Group 3 (p less than 0.005) but none between Group 3 and 2.
