DIAGNOSTIC VALUE OF MODERATE DILATATION OF THE LEFT VENTRICLE IN ASYMPTOMATIC (SILENT) ISCHEMIA

Goal of the study - defining of diagnostic and prognostic values of the moderate dilatation of the left ventricle in theasymptomatic (Silent) ischemia. The report was based on the investigation results of 185 patients, aged 35-55, who did not have typical stenocardia pain. Out of the given contingent, 117 patients who had the mild and moderate dilatation of the left ventricle were united under the name of moderate dilatation group. Another group of 68 patients, who did not have this pathology, was used as a control group. The statistical analysis was performed, using the program packet SPSS v.22. Our study showed that the majority of those asymptomatic patients, who showed moderate dilatation, had the positive exertion test on treadmill and the ischemia signs during holter's monitoring. Among them, ST segment depression (ST↓) or ST segment allevation (ST) and ventricular extrasystoles were credibly high. As the result of investigation, it was found, that the frequency of those people whose coronography showed more than 50% stenosis of any coronary and 30 to 50% stenosis, was convincingly high. The intact coronaries were found in only 11% of those patients, who had moderate dilatation, whereas in the contingent with no dilatation, it was 76% (p<0.05). Thus, we can use the moderate (mild) dilatation of the left ventricle for the primary diagnosing of the silent ischemia. The test is simple and non-invasive. It is characterized by high sensitivity and specificity and can be used for early diagnosing of silent ischemia and the prevention of cardiac cases.
