Enhanced External Counterpulsation (EECP), Cardiac Output
Impact of Enhanced External Counterpulsation (EECP) on Cardiac Force Index

Heart Disease, Heart Failure
Investigating Systemic and Local Vascular Responses to Apelin in the Context of Renin-angiotensin Upregulation
The apelin-APJ system is a relatively new discovery. It has generated interest in part due to it's apparent ability to counteract the renin-angiotensin system, which is frequently overactive in many cardiovascular disease.

Cardiac Diseases
Non-Invasive Determination of Cardiac Output by Inertgas Rebreathing Method
