P094 HYPERTENSION AT ADMISSION AFFECTS THE RESULTS OF CARDIAC SCINTIGRAPHY IN THE ELDER PATIENTS WITH ISCHEMIC HEART DISEASE

Background and Objective: The heart disease is the second most common cause of death after cancer in Japan. Since a myocardial ischemia leads directly to life prognosis, the evaluation of severity of myocardial ischemia is very important to reduce mortality in the patients with ischemic heart disease. The cardiac scintigraphy is less-invasive method to check it than cardiac catheter while results of cardiac scintigraphy are affected by aging and hypertension. The aim of this study is to evaluate the effect of both aging and hypertension at admission on the results of cardiac scintigraphy in the patients with ischemic heart disease. Methods: We recruited 102 patients with ischemic heart disease who were admitted to Chidoribashi General Hospital and underwent cardiac scintigraphy from April 2021 to March 2023. The various parameters such as patient's profile and results of cardiac scintigraphy were collected from electric medical records retrospectively. The comparison was statistically tested using JMP Pro 17. This study was approved by our ethical committee. Results: Thirty-one patients were under 70 years old and seventy-one patients were 70 years old or more. In elder patients, left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV) and the difference of LVEDV from LVESV at rest were more in the patients with hypertension at admission than in the patients without that. In contrast, no difference existed in younger patients. Conclusions: These results suggest that aging may change the ischemic status affected by hypertension.
