[Does the cardiogoniogram change following revascularization?].

19 patients with one-vessel coronary disease were studied by cardiogoniometry (CGM), a new computerized vectorcardiographic method, before and after revascularization. In 14 patients revascularization had been performed by the method of percutaneous transluminal angioplasty (PTCA) and in 5 patients by aortocoronary bypass operation. Although the majority of cases showed a good postoperative result, CGM parameters failed to demonstrate a significant change, i.e. a previous pathologic CGM remained unchanged. It therefore appears to be doubtful whether CGM is reliable enough to assess the results of revascularization, possibly because it is more sensitive to infarcted than potentially ischemic yet vital myocardium.
