Assessment of sex differences in ventricular-vascular coupling of left ventricular and aortic flow derived from 4D flow MRI in healthy, young adults

摘要: Abstract To gain further insight into male–female differences in cardiovascular conditions it is important to understand sex healthy populations. A previous study from our group of 39 young volunteers (20–35 years) paradoxically found that men had greater left ventricular (LV) kinetic energy (KE) but women LV vorticity. We reanalyzed cardiac four-dimensional flow MRI data 20 the original subjects (10 male and 10 female) quantify aortic addition flow. The combination parameters were then used calculate vascular coupling KE difference not ventricular-vascular LV-to-aortic was similar between women. Dimensional analysis account for output volume explained methods results this may be use understanding transported variables differences, aging, various conditions.
