Pulmonary venous flow velocity pattern, transmitral flow pattern, isovolumic relaxation time, and left ventricular fractional wall thinning were analyzed in 72 dogs with heart disease by transthoracic Doppler and M-mode echocardiography and compared with other noninvasive variables of left ventricular and left atrial systolic performance. Abnormal diastolic blood flow was found in 49 (68%) dogs, predominantly flow patterns suggestive of relaxation abnormality and increased filling pressures. Diastolic flow abnormalities despite normal systolic performance were found in 23 (32%) dogs of which 14 (61%) revealed clinical signs of heart disease. The diagnostic sensitivity of pulmonary venous flow parameters for echocardiographically detectable diastolic disturbance was found to be higher compared with the other noninvasive parameters of diastolic heart function measured. Diastolic filling pattern appear to correlate closer with functional status in many dogs with heart disease than indices of systolic performance.
通过经胸多普勒和M型超声心动图对72只患有心脏病的犬进行肺静脉血流速度模式、二尖瓣血流模式、等容舒张时间和左心室壁分数变薄分析,并与左心室和左心房收缩功能的其他非侵入性变量进行比较。49只(68%)犬发现舒张期血流异常,主要是提示舒张功能异常和充盈压升高的血流模式。23只(32%)收缩功能正常但有舒张期血流异常的犬中,14只(61%)有心脏病的临床体征。与测量的其他舒张期心功能非侵入性参数相比,肺静脉血流参数对超声心动图可检测到的舒张期紊乱的诊断敏感性更高。在许多患有心脏病的犬中,舒张期充盈模式似乎比收缩功能指标与功能状态的相关性更密切。
