目的应用声学定量技术(AQ)评价非对称性肥厚型心肌病(包括梗阻性和非梗阻性)患者右室收缩与舒张功能。方法应用声学定量技术分别对2004年7月至2005年10月辽宁省人民医院27例肥厚型梗阻性心肌病(HOCM)患者、35例肥厚型非梗阻性心肌病(HNCM)患者和30例正常对照组人群的标准心尖四腔心切面观进行分析。结果与对照组相比,肥厚型心肌病(包括梗阻型和非梗阻型)右室峰值快速充盈率与右房峰值快速充盈率之比(PRFR/PAFR)、右室快速充盈容积与右房收缩充盈容积之比(RF/AF)明显减低(P<0.05)。而右心室收缩功能指标EF与正常组相比差异无显著性。结论AQ为定量评价肥厚型心肌病患者的右室功能提供了新的方法。
Objective To evaluate the right ventricular systolic and diastolic function in patients with asymmetric hypertrophic cardiomyopathy (including obstructive and non-obstructive) using acoustic quantification (AQ). Methods Acoustic quantification technique was used to evaluate the clinical data of 27 patients with hypertrophic obstructive cardiomyopathy (HOCM), 35 patients with hypertrophic non-obstructive cardiomyopathy (HNCM) and 30 normal controls from July 2004 to October 2005 in Liaoning Provincial People’s Hospital. The standard apical four-chamber view of the control group was analyzed. Results Compared with the control group, the ratio of fast right ventricular filling ratio to right atrial peak fast filling ratio (PRFR / PAFR), right ventricular filling volume and right atrial systole in hypertrophic cardiomyopathy (including obstructive and nonobstructive) The ratio of filling volume (RF / AF) was significantly reduced (P <0.05). The right ventricular systolic function index EF compared with the normal group no significant difference. Conclusion AQ provides a new method for the quantitative evaluation of right ventricular function in patients with hypertrophic cardiomyopathy.
