摘　　要：目的采用实时三维超声心动图(real-time three-dimensional echocardiography,RT-3DE)评估正常高值血压对右心室功能的影响。方法收集笔者医院心内科门诊及体检中心的受试对象共152例,根据血压水平分为3组,即正常血压组50例、正常高值血压组52例和高血压1级组50例,均行超声心动图检查。比较各组的右心室超声心动图参数。结果高血压1级组RVEDV、RVESV较正常血压组增加,FAC、RVEF降低,差异均有统计学意义(P<0.05)。与正常血压组比较,正常高值血压组和高血压1级组的RVFLS、RVSLS均减小;与正常高值血压组比较,高血压1级组的RVFLS、RVSLS减小,差异有统计学意义(P<0.05)。结论RT-3DE可定量评价不同血压水平受试者的右心室功能,可以早期敏感地发现正常高值血压受试者的右心室心肌损害,为临床早期干预提供依据。Objective To evaluate the effect of High-normal blood pressure on right ventricular function by Real-time three-dimensional Echocardiography.Methods A total of 152 subjects were collected from the cardiology clinic and physical examination center of our hospital.They were divided into three groups according to their blood pressure levels,normal blood pressure group(50 cases),high-normal blood pressure group(52 cases),and hypertension stage 1 group(50 cases).Echocardiography was performed.The right ventricular three-dimensional echocardiography parameters were compared.Results The RVEDV and RVESV of the hypertension stage 1 group were larger than those of the normal blood pressure group,and the FAC and RVEF were reduced.The differences were statistically significant(P<0.05).Compared with the normal blood pressure group,the RVFLS and RVSLS of the high-normal blood pressure group and the hypertension stage 1 group were reduced.Compared with the high-normal blood pressure group,the RVFLS and RVSLS of the hypertension stage 1 group were decreased,and the difference was statistically significant(P<0.05).Conclusion RT-3DE can quantitatively evaluate the right ventricular function of subjects with different blood pressure levels,and can early and sensitively detect right ventricular myocardial damage in subjects with high-normal blood pressure,and provide a basis for early clinical intervention.
