【摘要】：目的：利用數(shù)據(jù)挖掘技術(shù)對(duì)高血壓病患者的臨床基本信息及心功能常規(guī)超聲測(cè)量指標(biāo)進(jìn)行挖掘，揭示出影響高血壓病心臟功能的影響因素及特征性指標(biāo)，揭示正常人及高血壓病心臟功能的特征及變化規(guī)律或趨勢(shì)。 方法：選擇2013年2月至2014年2月來(lái)我院行檢查的高血壓患者和正常健康人，采用高檔彩色多普勒超聲顯像儀，按照統(tǒng)一規(guī)范的檢查和測(cè)量方法獲取心臟功能的超聲指標(biāo)，，包括測(cè)量計(jì)算身高、體重、體表面積等形體指標(biāo)，通過(guò)二維超聲心動(dòng)圖獲取左室收縮功能（左室短軸縮短率、左室射血分?jǐn)?shù)、左室中層心肌縮短率）、左室舒張功能[二尖瓣血流E、A、E/A、DT、IVRT；肺靜脈血流S、D、S/D、SFF（收縮充盈分?jǐn)?shù)）、Ar以及Ar-A（表示Ar與MV A持續(xù)時(shí)間之差值）；二尖瓣舒張?jiān)缙谘鞑ド⑺俾�；二尖瓣環(huán)組織多普勒運(yùn)動(dòng)速率e’、a’、E/e’]、右室收縮功能[右室面積變化率、三尖瓣環(huán)收縮運(yùn)動(dòng)位移、組織多普勒三尖瓣環(huán)側(cè)壁點(diǎn)收縮期峰值運(yùn)動(dòng)速度、右室Tei指數(shù)（MPI指數(shù)）]、左心房及右心房容積等。接著將影響高血壓病的相關(guān)因素，如血壓、年齡、體重、性別、血糖、血脂、吸煙、飲酒等情況，與測(cè)量心臟功能的各項(xiàng)指標(biāo)結(jié)合建立數(shù)據(jù)庫(kù)，利于數(shù)據(jù)挖掘技術(shù)構(gòu)建高血壓病心臟功能超聲數(shù)據(jù)模型。 結(jié)果：建立高血壓病患者的臨床基本信息及心臟功能的常規(guī)測(cè)量指標(biāo)的關(guān)系數(shù)據(jù)庫(kù)，通過(guò)關(guān)聯(lián)規(guī)則挖掘出高血壓病心臟功能改變的主要影響因素及特征性指標(biāo)，初步揭示出高血壓病心臟功能之間的演變規(guī)律并得出其演變趨勢(shì)圖。 結(jié)論：利用數(shù)據(jù)挖掘技術(shù)，可以得到影響高血壓病的關(guān)鍵性影響因素和心臟功能改變的特征性指標(biāo)，演變不同病程下的高血壓病心臟功能演變的趨勢(shì)圖，對(duì)臨床的輔助診療具有一定的現(xiàn)實(shí)意義。
[Abstract]:Objective: to explore the basic clinical information and echocardiographic parameters of hypertension patients by using data mining technology, and to reveal the influencing factors and characteristic indexes of hypertensive heart function. To reveal the characteristics and changes of heart function in normal people and hypertension. Methods: high grade color Doppler ultrasound imaging instrument was used to obtain the echocardiographic parameters of heart function in patients with hypertension and healthy persons who had been examined in our hospital from February 2013 to February 2014. The left ventricular systolic function was obtained by two-dimensional echocardiography (left ventricular shortening rate, left ventricular ejection fraction, etc.) Left ventricular diastolic function, left ventricular diastolic function [mitral flow, E / A, E / A] IVRTT; Pulmonary vein blood flow, S / D, SFF (systolic filling fraction, ar and Ar-A( indicating the difference between ar and MV A duration); early diastolic velocity of mitral valve; Mitral annular tissue Doppler motion rate E / E', right ventricular systolic function [right ventricular area change rate, tricuspid annular systolic movement displacement, tissue Doppler tricuspid annular systolic peak velocity, right ventricular area change rate, tricuspid annular systolic displacement, tissue Doppler tricuspid annular systolic peak velocity, Right ventricular Tei index, left atrium and right atrium volume, etc. Then the related factors, such as blood pressure, age, weight, sex, blood sugar, blood lipid, smoking, drinking, etc., were combined with various indexes to measure heart function. It is helpful to construct ultrasonic data model of hypertensive heart function by data mining technology. Results: the basic clinical information of essential hypertension patients and the relation database of routine measurement indexes of heart function were established. The main influencing factors and characteristic indexes of the changes of heart function in hypertension were found out by association rules. The evolution of heart function in hypertension was revealed and the trend map was obtained. Conclusion: by using data mining technique, the key factors affecting hypertension and the characteristic indexes of heart function change can be obtained, and the trend map of heart function evolution of hypertension under different course of disease can be obtained. It has certain practical significance for clinical auxiliary diagnosis and treatment.
