The increased ACE2/ ACE mRNA ratio in the patients with grade ⅱ CHF, may be due to cardiac compensation, indicating the promotion of Ang ⅱ degradation. 轻度心衰患者ACE2/ACEmRNA比值升高可能是心脏的代偿机制,促进AngⅡ降解,增加Ang1-7合成,保护残存的心功能。
Conclusion During perioperative stage of CABG, patients 'right ventricular function are enforced and low cardiac output manifestations were shown during the early stage of postoperative period, but rapidly overcome by body compensation. 结论行CABG手术的患者在围术期右心功能代偿性增加;术后早期患者均出现不同程度低心排血量的表现,但很快就能被机体代偿。
Result The brain blood oxygen content and average relativity of brain blood oxygen wave in patients with chronic cardiac insufficiency were significantly lower than those in cardiac compensation cases ( including healthy person, patients with coronary heart disease or hypertensive heart disease)( P < 0.01). 结果慢心衰病人与对照组相比血氧含量及血氧波形相关系数均降低(P<0.01)。
Background and Objectives: Myocardial fibrosis is an important and common pathologic process which plays an indispensable role in the change of cardiac function from compensation to decompensation and the change of myocardial remodeling from reversibility to irreversibility. 背景与目的:心肌纤维化(myocardialfibrosis)是一种重要而常见的病理过程,它在心脏功能从代偿到失代偿转变、心肌重塑从可逆到不可逆变化中发挥至关重要的作用。
All patients with preoperative cardiac and pulmonary function tests were normal or within the scope of the compensation, lung ventilation was more than 90% SpO2 finger. 所有患者术前心、肺功能检查均正常或在代偿范围之内,双肺通气指端Sp02均大于90%。
