좌심실 조영술에 의한 좌심실 기능검사에 관한 연구 = The Evaluation of Left Ventricular Function by Left Ventriculography

다국어 초록 (Multilingual Abstract)

Left ventricular end-diastolic pressure(LVEDP), ejection fraction(EF) and circumferential fiber shortening(CFS) have been used for the assessment of left ventricular performance. Among 76 patients with heart disease. 15 patients had pure mitral stenoeis, 44 had mitral stenosis associated with other mild valvular disease, 7 had cardiomyopathy and 10 had coronary artery disease. Cardiac catheterization was performed and left ventriculography was done with right anterior oblique projection, and LVEDP, EF, CFS and segmental fiber shortening(SFS) were obtained. The results of the study were: 1) The LVEDP was normal in patients with pure mitral stenosia(7,7±0.74 mmHg) and in patients with mitral stenosis associated with mild valvular disease(8.5±0.52 mmHg), The LUEDP was significantly elevated in patients with cardiomyopathy(20.6±2,50 mmHg) and in patients with coronary artery disease(22.8±3.12 mmHg). 2) In patients with pure mitral stenosis and in patients with mitral stenosis associated with other mild valvular disease, the EF was normal, 57.9± 3.03% and 56.0±1.85%, respectively, while the EF was markedly reduced in patients with cardiomyopathy(27. 7±4. 33%) and in patients with coronary artery disease(34.1±5.28%). 3) The extent of CFS was normal in patients with pure mitral stenosis(33.5±3.06%) and was slightly reduced in patients with mitral stenosis associated with other mild valvular disease(29,4±1.34,). In cardiomyopathy and coronary artery disease, the extent of CFS decreased markedly 16.2±3.28% and 16.3±3.56%, respectively. 4) Estimation of the SFS 4y the percentage of shortening of each hemiaxis seemed to be a better method for evaluation of left ventricular contractility in patients with coronary artery disease. 5) Left ventricular end-diastolic pressure correlated well with ejection fraction and circumferential fiber shortening.
