[The cholecysto-coronary syndrome observed with polygraphic and echocardiographic examinations]

The cholecysto-coronary syndrome already many times observed by various Authors at the standard electrocardiogram and after effort with not much significative results, has been studied by our group with a polygraphic and echocardiographic method. 55 subjects aged between 30 and 55 years have been examined, to each of them besides a standard electrocardiogram and after effort a polygraphic examination including a tracing of electrocardiogram, a phonocardiogram, and a carotid pulse has been made, after the STEM, TEVS, TC, TCIV, PPE and the TEVS/PPE have been calculated. The parameters obtained have been compared with the ideal values of the subject in examination, calculated according to the formula of Diamond and Killip. Moreover an echocardiographic examination has been performed in 10 of the 55 patients, both to exclude valvular anomalies and ventricle enlargements, and to calculate the velocity of the contraction of the circumferential fibres (Vcf). The examination performed pointed out an increase of the TCIV and PPE with decrease of the ratio TEVS-PPE at the polygraphic examination and moreover a decrease of the Vcf at the echocardiogram. From the whole of the results obtained we can conclude that the cholecysto-coronary reflex determines a decrease of the contribution of the O2 to the myocardium, of a limited entity, so much that it doesn't give clear signs in the standard ECG, but sufficient to establish a suffering of the sarcomer that manifests itself with an alteration of its contraction velocity.
