What is the Origin of Cardiovascular Performance?

The term is derived from the Greek kardia (heart) and the Latin vasculum (small vessel), and its clinical evaluation has been central to human physiology since the development of exercise stress testing. The focus on 'performance' highlights a functional assessment beyond simple pathology.

What is the Mechanism of Cardiovascular Performance?

Performance is primarily regulated by the autonomic nervous system and various circulating hormones, including catecholamines and natriuretic peptides. During exercise, hormonal signals increase heart rate and stroke volume, thereby increasing cardiac output. Simultaneously, vasodilation in active muscles, coupled with vasoconstriction elsewhere, redirects blood flow to maximize oxygen delivery and metabolic efficiency.

Cardiovascular Performance

Meaning

Cardiovascular Performance is the clinical measure of the heart and vascular system’s efficiency and capacity to deliver oxygenated blood and nutrients to working tissues while effectively removing metabolic waste products. Key indicators include maximal oxygen uptake (VO2 max), cardiac output, heart rate variability, and vascular elasticity. Optimal performance in this system is a fundamental determinant of physical endurance, metabolic health, and overall longevity.
