Stress doppler echocardiography in connective tissue disease patients without overt pulmonary arterial hypertension

Background Pulmonary arterial hypertension(PAH) is a common complication of connective tissue disease(CTD) and confers a worse prognosis. Stress doppler echocardiography(SDE) can detect early pulmonary vasculopathy and assess right heart function in patients with pulmonary arterial hypertension. In this study, the SDE was applied to analyze the degree of pulmonary vascular lesion and the function of right heart in CTD patients without overt PAH. Methods CTD patients without overt PAH were divided into exercised-induced pulmonary hypertension(EIPH) group and non-EIPH group depending on whether tricuspid regurgitation(TR) exceeded 3.1 m/s during exercise and assessed by echocardiography at rest and during exercise. The data of right ventricular function and the slope of the incremental of the mean pulmonary artery pressure and cardiac output(ΔmPAP/ΔCO) were analyzed. Results Forty-seven CTD patients without overt PAH(35 female, mean age 40.3±12.0 years) were enrolled and divided into EIPH group(n=21) and non-EIPH group(n=26). Patients with systemic sclerosis(SSc) were more likely to have EIPH(47.6% vs. 28.6%, P0.05) than those with systemic lupus erythematosus(SLE). Patients in EIPH group had a higher value of ΔmPAP/ΔCO than that of the non-EIPH group(4.5±3.1 vs. 2.2±1.3, P0.05). SSc was more prevalent in CTD patients and the symptoms of dyspnea occurred more often in EIPH group(52.4%), indicating a pressure-flow mismatch induced by exercise. However, the cardiac function demonstrated by left ventricular ejection fraction(LVEF), tricuspid annular plane systolic excursion(TAPSE),DTI-Derived S'-wave velocity(S') and right ventricular fractional area change(RVFAC), as well as functional reserve reflected by the changes of TAPSE, S', RVFAC before and after exercise, did not differ significantly between the two groups. Conclusions Although right ventricular(RV) reserve function does not change much before and after exercise, patients in EIPH group have a higher value of ΔmPAP/ΔCO than that of the non-EIPH group and more likely to have symptoms during exercise. Thus, to assess the potential for pulmonary vascular disease, echocardiography should be performed at rest and during exercise.[S Chin J Cardiol 2019;20(1):31-36]     

115例先天缺陷产前诊断分析

产前诊断又称宫内诊断，就是在出生前对胎儿的健康情况做出诊断，是近代医学遗传学与临床医学相结合而发展起来的一门科学。医疗保健机构对胎儿进行先天性缺陷和遗传性疾病的诊断及相应的筛查，是《母婴保健法》赋予的职责，是优生优育，提高出生人口素质的必要手段：     

婚前医学检查情况分析

目的探讨婚前医学检查（简称婚检）者的健康现状及对优生优育的影响。方法对2009年9月至2010年9月在我所自愿婚检青年的资料进行回顾性分析,其中男婚检3379人,女婚检3435人。结果疾病检出率男性为50.22%,女性为36.39%,其中男性以生殖系统疾病为主,乙肝三系及肝功能异常在男女双方所占比例较高,分别是男的占20.75%,女的占8.82%。性病也占有一定的比例,并有逐年增加的趋势。结论婚检青年的健康状况不容乐观,且会影响优生优育,婚前医学检查工作仍有重要意义。     

655例高危妊娠临床分析

目的:探讨剖宫产率居高不下的主要影响因素,为降低剖宫产率提供依据。方法:对2004年1月￣2006年1月在全区城镇住院分娩的病例采用回顾性分析。结果:孕期高危筛选377例,筛选率34.1%;产时高危506例,发生率45.8%;孕期高危合并产时高危228例,发生率20.6%;孕期未筛选的产时高危278例,发生率25.2%。其中剖宫产477例,剖宫产率43.2%;产钳57例,发生率5.2%。结论:从孕期开始筛选高危妊娠,严格把握剖宫产手术指征,可降低剖宫产率。
