[Does the cardiogoniogram change following revascularization?]
1Kardiologische Abteilung, Medizinische Universitätsklinik, Inselspital Bern.
Insights
Cardiogoniometry (CGM) did not show significant changes after coronary revascularization in patients with one-vessel disease. This suggests CGM may not be reliable for assessing revascularization outcomes, potentially due to sensitivity to infarcted tissue.
Area of Science:
- Cardiology
- Medical Technology
Context:
- One-vessel coronary artery disease requires effective treatment and assessment methods.
- Revascularization procedures like PTCA and bypass surgery aim to restore blood flow.
- Evaluating the success of revascularization is crucial for patient outcomes.
Purpose:
- To investigate the utility of cardiogoniometry (CGM) in assessing the results of coronary revascularization.
- To compare CGM findings before and after revascularization in patients with one-vessel coronary disease.
Summary:
- Nineteen patients with one-vessel coronary disease underwent cardiogoniometry (CGM) before and after revascularization (14 PTCA, 5 bypass).
- Despite good clinical outcomes in most patients, CGM parameters did not show significant changes post-revascularization.
- Pathological CGM findings persisted in most cases, questioning its reliability for assessing revascularization success.
Impact:
- The study raises doubts about the reliability of cardiogoniometry for evaluating coronary revascularization outcomes.
- CGM's potential higher sensitivity to infarcted versus ischemic myocardium might explain the lack of significant changes.
- Further research is needed to validate or refine CGM's role in post-revascularization assessment.
Abstract:
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.
