| Outline of Final Research Achievements |
In this study, to explore myocardial damage due to irradiation, we use averaged electrocardiogram that can identify microscopic myocardial injury. Interventions other than the above were judged to deviate from regular medical practice, therefore this study was approved in our hospital as a prospective clinical trial considerably later than the original schedule. About 40% of the case arrival number (30 cases) was accumulated and analyzed as much as possible this time. No significant change was observed by irradiation with fQRS-d, RMS 40ms, LAS 40μV which are indicators of the averaged electrocardiogram. In E/e’ which is an index of diastolic cardiac function at echocardiogram, an upward trend was observed after 6 months of irradiation, although a statistically significant difference was not observed. This study will continue as an in-hospital clinical trial and accumulate cases and plan to reanalyze as soon as the number of cases is reached.
