Arterial-Ventricular Coupling:
Role of the Stiffness
Vlacahopoulos C, Cardiology 2010
The performance of the cardiovascular
system depends on the interaction of its
components. The left ventricle pumps is
stroke volume into the arterial system,
which then delivers the flow to the tissues.
Thus, optimal cardiovascular function
requires appropriate coupling of the left
ventricle and arterial system.

Effect of Exercise in LV Paramters in
Patients with HF with Preserved EF
Borlaug BA, Eur Heart J 2011
In HFpEF patients, moderate exercise leads to a steep increase
in proximal afterload that is understimated at rest and is
associated with unfavorable ventricular-arterial coupling and
exrecise intolerance.
