摘要目的定量确定种群变异以及左心室小梁形成与左心室功能、结构和临床变量间的关系。材料与方法该研究经过与HIPAA兼容的多中心研究机构伦理委员会批准。所有参与者提供书面知情同意。多种群参与者的动脉粥样硬化研究以左心室小梁形成的心脏MR数据进行评估量化作为一个分形维数(FD)。整个受试者群体没有心脏病、心脏肥大、高血压、糖尿病,根据体质量指数(BMI)分为3个参照组(BMI<25 kg/m~2;25 kg/m~2≤BMI<30 kg/m~2;BMI≥30 kg/m~2),探
Abstract Objective To quantitatively determine the relationship between population variation and left ventricular trabecular formation and left ventricular function, structure and clinical variables. Materials and Methods The study was approved by HIPAA-compliant multi-center research ethics committee. All participants provide written informed consent. Atherosclerosis Study of Multiple Population Participants Cardiac MR data of left ventricular trabeculae were evaluated for quantification as a fractal dimension (FD). The entire cohort was free of heart disease, hypertrophy, hypertension, and diabetes and was divided into 3 reference groups (BMI <25 kg / m 2; 25 kg / m 2 ≤ BMI <30 according to body mass index kg / m ~ 2; BMI≥30 kg / m ~ 2)
