目的:應(yīng)用應(yīng)變率探討不同左心室構(gòu)型的原發(fā)性高血壓患者左心室長軸方向應(yīng)變－應(yīng)變率成像的變化,及其與EF、FS及二尖瓣血流測量評價左室功能的對照研究。方法:采用M型、二維、多普勒超聲及應(yīng)變率成像技術(shù),測量左室室壁厚度、左室內(nèi)徑、EF、FS,二尖瓣血流頻譜E、A及左室平均應(yīng)變ε,應(yīng)變率S、e、a。結(jié)果:高血壓離心性肥厚組EF、FS明顯低于對照組,高血壓其余各組EF、FS與對照組無統(tǒng)計學(xué)差異;收縮期應(yīng)變率S應(yīng)變ε在五組間差異均有顯著性意義:高血壓各組較正常對照組減小(I--Ⅴ呈遞減);舒張期應(yīng)變率e減低、a增高,e/a比值減小,各組間存在統(tǒng)計學(xué)差異(Plt;0.05); E/A,e/a結(jié)果大體一致。結(jié)論:應(yīng)變率成像為臨床提供了一個敏感、簡便、可靠的評價原發(fā)性高血壓患者左室心肌功能的指標(biāo)。
摘要:目的:觀察美托洛爾對高血壓并慢性心衰(CHF)患者的心功能影響及臨床療效。方法:擇高血壓并高心病或冠心病60例,心功能Ⅱ～Ⅳ級的患者,隨機(jī)分為兩組,常規(guī)組(30例),給與控制血壓、利尿、轉(zhuǎn)換酶抑制劑(ACEI)、洋地黃治療。美托洛爾組(30例),在常規(guī)治療基礎(chǔ)上加用美托洛爾。結(jié)果：美托洛爾組臨床顯效率(667%),總有效率(93.4%),較常規(guī)組顯著提高(Plt;0.05)。美托洛爾組與常規(guī)組治療前后,心率、血壓、左室舒張末期直徑、左室收縮末期直徑、左室射血分?jǐn)?shù)、心輸出量、E/A、等容舒張期時間均有顯著改善(美托洛爾組Plt;0.01,常規(guī)組Plt;0.05),且美托洛爾組上述指標(biāo)改善更明顯(Plt;0.01或Plt;0.05)。結(jié)論:美托洛爾顯著改善高血壓并慢性心力衰竭患者的心功能,是一種安全有效的治療方法。Abstract: Objective: To observe US to hold Luo river to hypertension and the chronic heart failure (CHF) patient’s heart function influence and the clinical curative effect. Methods: Selects hypertension and the high worry or the coronary disease 60 examples, the heart functionⅡ~ⅣThe level patient, divides into two groups stochastically, the conventional group (30 examples), gives the control blood pressure, the diuresis, the transformation enzyme inhibitor (ACEI), the digitalis treatment. US holds Luo river Zu (30 examples), adds in the conventional treatment foundation with US holds Luo river. Results: US holds the Luo river group clinical obviously efficiency (66.7%), the total effectiveness (93.4%), compares the conventional group remarkable enhancement (Plt;0.05). Around US holds Luo river Zu and the conventional group treats, the heart rate, the blood pressure, the left room diastole last stage diameter, the left room contraction last stage diameter, the left room shoot the menstruation number, the cardiac output, E/A, the constant volume relaxing period time to have the remarkable improvement (US to hold Luo river ZuPlt;0.01, conventional group (P lt;0.05), and US holds the Luo river group above target improvement to be more obvious (Plt;001 or Plt;0.05). Conclusion: US holds Luo river obviously to improve hypertension and the chronic heart
摘要:隨著單純性肥胖兒童數(shù)量的迅速增長，肥胖對兒童左心功能的影響逐漸引起了大家的重視，對其進(jìn)行早期評估已很有必要。本文即從常規(guī)超聲心動圖、組織多普勒超聲心動圖、應(yīng)變與應(yīng)變率、Tei指數(shù)等四個方面對現(xiàn)階段通過超聲技術(shù)早期檢測與評價肥胖兒童左心功能的方法做一綜述。
