초록

64 절편 MDCT를 이용하여 측정된 좌심실 구혈률에 성별과 연령, 체질량지수, 혈압, 심박동수 등의 요인이 영향을 미치는지 비교 분석하였다. 164명(남자 84명, 여자 80명)을 대상으로 혈압, 체질량지수, 심박동수를 측정하였고, 심장 CT 검사를 실시하여 좌심실 구혈률을 구하였다. 체질량지수 25kg/$m^2$ 미만 군에서 좌심실 구혈률은 52.00${\pm}$118.95%, 25 kg/$m^2$이상 군에서 59.50${\pm}$16.05%였다(p<0.05). 정상 혈압군에서 좌심실 구혈률이 57.26${\pm}$17.84%, 고혈압군에서는 49.95${\pm}$17.63%로 고혈압군에서 유의하게 낮았다(p<0.05). 분당 심박동수 60회 미만 군에서는 60.76${\pm}$17.26%, 60-70회군에서 54.14${\pm}$16.56%, 70회 이상 군에서 50.83${\pm}$20.56%였다(p<0.05). 좌심실 구혈률과 연령(r=-0.283), 심박동수(r=-0.231)는 각각 음의 상관관계가 있었고, 체질량지수(r=0.228)와는 양의 상관관계가 있었다. 좌심실 구혈률에 영향을 미치는 요인으로는 연령, 체질량지수, 수축기혈압, 심박동수 등이었다. 결론적으로 연령, 체질량지수와 혈압, 심박동수에 따라서 구혈률이 차이가 나므로 이를 확인하여 평가하여야 한다.

This study was to analysis what factors could affect left ventricle ejection fraction(LVEF) using 64-slice multidetector CT. 164 patients(84 men, 80 women) had a cardiac CT in this study, and their blood pressure, body mass index(BMI), heart rate(HR) measured. LVEF was 52.00${\pm}$18.95% in below 25kg/$m^2$, 59.50${\pm}$16.05% in above 25kg/$m^2$ of BMI. LVEF was 57.26${\pm}$17.84% in normal blood pressure group(NBPG), 49.95${\pm}$17.63 in hypertension group(HG). LVEF was 60.76${\pm}$17.26 in below 60 beats/min, 54.14${\pm}$16.56 in 60-70 beats/min, 50.83${\pm}$20.56 in above 70 beats/min of HR. LVEF was negatively correlated with age, HR(r=-0.283 p<0.05, r=-0.231 p<0.05. respectively). And LVEF was positively correlated with BMI(r=0.228 p<0.05). A measurement of LVEF at cardiac CT by using MDCT may be considered to age, blood pressure, heart rate and BMI.
