摘要

科技的進步，減少基本日常的身體活動量，肥胖盛行率提升，且不良生活型態更導致慢性疾病日益盛行，伴隨相關心臟功能異常之併發症，近年來肥胖已經有年輕化趨勢，因此，體重過重肥胖者是否有潛在性心臟功能之異常影響。目的：探討年輕肥胖女性之體重與心臟功能相關影響。方法：本研究針對20－29歲年輕肥胖女性之血壓與心臟血液動力學與肥胖女性體重進行相關研究。利用TANITA身體組成分析儀、血流動力分析儀（PhysioFlow）、TERUMO ES-P2000血壓計等儀器，進行身體組成、心臟功能、血壓等參數評估。結果：本究共招募54位肥胖女性（年齡M=21.72±1.78、身高M=159.41±5.21cm、體重（W）M=75.81±8.76kg、身體質量指數M=29.61±3.42、腰圍M=87.03±9.45cm、臀圍M=106.24±8.9cm、腰臀圍比例M=0.82±0.07）；W與『血壓值』相關性發現與收縮壓（SBP），脈壓（APP）等兩參數明顯呈現正關聯（p＜.05），分別為r（52）=.363, p=.007及r（52）=.292,p=.032；W與『血液動力學』相關性發現：與心搏指數（SVI：r（52）=-.310,p=.023）明顯呈現負相關、與舒張末期容積（EDV：r（52）=.381, p=.004）、收縮末期容積（ESV：r（52）=.350,p=.009）等明顯呈現正相關（p＜.05）。結論：由於肥胖者多數比例容易造成血液射出的壓力，致使心室肥厚的增加，也因為心臟長時間此狀況運作，將造成心臟功能的負荷僵硬壓力，使得SBP, ABP的提升；肥胖者血液在心室射出的阻力上升，長時間心臟阻力提高，使得SV無法順應性的進行血液充分的射出，更因體表面積造成SVI的下降、更由於心室舒張功能的不全，血液射出不足，造成EDV, ESV因體重增加而提升。

Advances in science and technology have reduced the amount of basic daily physical activity, the prevalence of obesity has increased, and poor lifestyles have led to the increasing prevalence of chronic diseases. Accompanied by complications related to abnormal heart function, obesity has become younger in recent years. Therefore, weight whether the overweight and obese people have potential abnormal effects on heart function. Purpose: To explore the correlation between body weight and heart function in young obese women. Methods: In this study, we have studied the relationship between body weight and blood pressure, hemodynamics in obese women aged 20-29 years and obese women to investe. The body composition, cardiac function, blood pressure were evaluated by TANITA body composition analyzer, physio Flow cardiac function analyzer, TERUMO ES-P2000 blood pressure monitor and other instruments. Results: The subjects were recruited 54 obese women (age M= 21.72 ±1.78, height: M= 159.41± 5.21cm, body weight(W): M=75.81± 8.76kg, Body Mass Index: M=29.61± 3.42, Waist Circumference: M=87.03±9.45cm, Hip Circumference: M=106.24± 8.9cm, Waist Hip Ratio M=0.82± 0.07); W and pressure value correlation found: W between Systolic Blood Pressure (SBP), Arterial Pulse Pressure (APP) were significantly higher (p＜0.05) and displayed positive correlation (p＜.05), respectively: r(52)=.363, p=.007 , r(52)=.292, p=.032; W and hemodynamics correlation found: W with Stroke Volume Index (SVI: r(52)=-. 310, p=.023) displayed negative correlation (p＜.05), W with End-Systolic Volume (ESV: r(52)=.350, p=.009), End-Diastolic Volume (EDV: r(52)=.381,p=.004 ), significant positive correlation (p＜.05). Conclusion: Because the proportion of obese people is likely to cause the pressure of blood injection, resulting in increased ventricular hypertrophy, also because cardiac for a long time this situation will cause cardiac function load stiffness, increased SBP, ABP values; These obese not only blood in the ventricle injection resistance have increased, long time to rise up the cardiac resistance, so SV can not adapt to the full injection cycles of blood, but also due to self body surface area caused by SVI decline, but also due to ventricular diastolic dysfunction, blood injection, resulting in EDV, ESV due to weight increase and increase.
