To estimate the capabilities of the new technique radionuclide 4D-tomoventriculography (4D-RTVG) versus conventional methods, such as radionuclide equilibrium ventriculography (REVG), ECG-synchronized single photon emission computerized tomography (SPECT), and echocardiography (EchoCG), in the evaluation of systolic and diastolic dysfunction in patients with coronary heart disease (CHD).
The study included 29 patients (19 males and 10 females) aged 43 to 66 years who had CHD. The diagnosis of CHD was established on the basis of coronary angiographic findings when the signs of coronary atherosclerosis were found. All the patients underwent 4D-RTVG, REVG, myocardial ECG-synchronized SPECT, and Echo CG.
There was a strong correlation of the values obtained by 4D-RTVG versus REVG and EchoCG when ejection fraction and left ventricular (LV) end-diastolic volume and the indices reflecting LV blood filling and ejection velocity were estimated. The correlation between the values provided by 4D-RTVG and myocardial ECG-synchronized SPECT females was slightly weaker.
The findings suggest that 4D-RTVG is highly reliable in evaluating both LV systolic and diastolic functions. That fact the technique is easy-to-use and mini-invasive shows that it may be clinically applied.
评估新技术放射性核素四维心室造影(4D-RTVG)与传统方法,如放射性核素平衡心室造影(REVG)、心电图同步单光子发射计算机断层扫描(SPECT)和超声心动图(EchoCG),在评估冠心病(CHD)患者收缩和舒张功能障碍方面的能力。
该研究纳入了29例年龄在43至66岁之间的冠心病患者(19例男性和10例女性)。当发现冠状动脉粥样硬化迹象时,根据冠状动脉造影结果确立冠心病诊断。所有患者均接受了4D-RTVG、REVG、心肌心电图同步SPECT和Echo CG检查。
在评估射血分数、左心室(LV)舒张末期容积以及反映LV血液充盈和射血速度的指标时,4D-RTVG与REVG和EchoCG所获得的值之间存在很强的相关性。4D-RTVG与心肌心电图同步SPECT在女性中提供的值之间的相关性稍弱。
研究结果表明,4D-RTVG在评估LV收缩和舒张功能方面高度可靠。该技术易于使用且微创这一事实表明它可能具有临床应用价值。
