目前识别心血管病风险不同分层的血清尿酸水平仍未确定。采用基于人群的大数据,研究人员评估了总死亡和与心血管病死亡(cardiovascular mortality,CVM)风险增加的血清尿酸水平。尿酸与心脏健康(uric acid right for heart health,URRAH...目前识别心血管病风险不同分层的血清尿酸水平仍未确定。采用基于人群的大数据,研究人员评估了总死亡和与心血管病死亡(cardiovascular mortality,CVM)风险增加的血清尿酸水平。尿酸与心脏健康(uric acid right for heart health,URRAH)研究是一项收集意大利几个基于大型人群纵向研究大数据的多中心回顾性观察性研究(随访20年),患者均在意大利高血压协会的高血压诊所就诊。展开更多
血清尿酸水平与左心室肥厚(left ventricular hypertrophy,LVH)的相关性存在争议,血尿酸预测LVH发生的作用目前尚不清楚。本研究对PAMELA(pressioni arteriose monitorate E loro associazioni)研究的受试者进行为期10年的随访以...血清尿酸水平与左心室肥厚(left ventricular hypertrophy,LVH)的相关性存在争议,血尿酸预测LVH发生的作用目前尚不清楚。本研究对PAMELA(pressioni arteriose monitorate E loro associazioni)研究的受试者进行为期10年的随访以评估血清尿酸与新发LVH的关系。展开更多
