Independent risk factors for the development of acute heart failure ( ahf ) include age , male gender , lower systolic blood pressure on admission to hospital , elevated c - reactive protein , and renal dysfunction , research aimed at characterizing the condition reveals 急性心力衰竭（ ahf ）的独立危险因素包括老龄、男性、入院时的低收缩压、 c ?反应蛋白升高以及肾功能不全，根据一项旨在描述这些因素特征的研究显示。
The researchers then focused on the genetic profiles , or genotypes , of more than 1 , 200 men and women whose systolic ( the higher number in a bp reading ) and diastolic ( lower number ) measurements fell at the extreme ? highest and lowest ? percentiles of distribution 然后研究人员就开始研究收缩压（血压读数中高的数值）和舒张压（血压读数中低的数值）属于非常高或非常低水平的1200位男性和女性病人的基因表型。
This pressure is usually described in terms of millimeter mercury mmhg . the pressure recorded during contraction of heart is called " systolic blood pressure " , and the pressure recorded during relaxation of heart is called " diastolic blood pressure " 通常量度压力是以毫米水银柱mmhg为单位，心脏收缩时的压力叫收缩压，通常是120 mmhg左右，心脏舒张时的压力叫舒张压，通常是80 mmhg左右，记录如下120 80 mmhg 。
These new findings indicate that heart failure patients with higher systolic blood pressures had substantially lower death rates compared to patients with lower systolic pressures , and that lower systolic pressures may indicate more advanced disease and a poorer prognosis 这些新的发现显示，与那些收缩压较低的患者相比，收缩压较高的心力衰竭患者死亡率较低，收缩期血压较低可能意味着病情的进一步进展和预后不良。
Systolic blood pressure , a readily available vital sign taken at hospital admission , has been found to be a key factor in predicting mortality risk and revealing important disease characteristics for heart failure patients , according to a team of academic researchers 根据一个研究队伍的研究结果显示：收缩压，是住院患者非常容易获得的一个指标，现在认为它是预测心力衰竭患者死亡风险和反映疾病重要特征的关键因素。
The researchers report in the archies of internal medicine that confounding factors included body mass index , hypertension , systolic blood pressure , serum cholesterol leel , smoking , diabetes mellitus , left entricular hypertrophy on the electrocardiogram , and the use of cardiac medication 学者在《内科文档》中报道，混杂致病因素包括体重指数，高血压，收缩压，血清胆固醇水平，吸烟，糖尿病，心电图显示左室肥厚，使用心脏病药物。
