Supplementary Issue: Heart Failure: An Exploration of Recent Advances in Research and Treatment

摘要: Abs Act: Ejection fraction (EF) has been viewed as an important index in assessing the contractile state of left ventricle (LV). However, it is frequently inadequate for diagnosis and management heart failure (HF), a significant subset HF patients have found to reduced EF (HFrEF) whereas others preserved (HFpEF). It should be noted that function LV dependent on both preload afterload, well its intrinsic state. Furthermore, stroke volume (SV) properties arterial system (AS). Thus, LV-arterial inter action plays role those with HF. This aspect investigated through analysis specific parameters involved coupling AS. includes contractility systolic/diastolic indices LV. AS afterload such vascular stiffness compliance, their derived coefficient, are also investigated. We conclude parameters, which relate structural changes, most appropriate quantifying LV–AS interaction.
