[Comparison of echocardiography, vectorcardiography, electrocardiography, coronarography and ventriculography in coronary heart disease].
Fifty patients (9 women, 41 men) with angina pectoris, aged from 22 to 59 years, were examined by means of one- and two-dimensional echocardiography (ECHO), vectorcardiography (VCG) using the McFee-Parungao system of leads, standard 12 lead electrocardiography (ECG), coronarography (CAG), and ventriculography (VG). I of isolated positivity of either of these methods ans considererl as patse positivity and presence or absence of positivity in combination of at least two methods (ECG exeluted) astme positivity, or true negativity then VCG was found to have the highest sensitivity (96%), negative predictive value (80%), as well as the highest overall predictivity (83%), while ECHO had the lowest values, i.e. 55%, 36%, 64%, respectively. On the other hand, ECHO was leading in specificity and positive predictive value with 100%, whereas VCG ranked lowest with 62% and 83% respectively. The combination of ECHO and VCG versus CAG and/or VG positivity exhibited and 80% specificity, 90% sensitivity, 90% positive predictive value and 86% overall predictivity when stenosis of over 50% was considered to be criterion. If obstruction was required the figures were to 75%, 94%, 83% and 86% respectively. ECHO and VCG are complementary noninvasive methods able to predict the results of CAG and VG and have a good predictive value when lowing for mere presence of focal myocardial injury.
