Physical Condition for the Coronary Artery Disease Patients-Juniper Publishers
JUNIPER PUBLISHERS-OPEN ACCESS JOURNAL OF CARDIOLOGY & CARDIOVASCULAR THERAPY Keywords: Aerobic exercise; Cardiac output; Maximal oxygen uptake Coronary Artery Disease Considerations A systematic review estimated that inactivity is responsible for 6% of the burden of disease from coronary heart disease worldwide [1]. CAD influence on work capacity and physical performance has been widely investigated. Myocardial functional changes include declines in maximum heart rate, stroke volume, left ventricular contractility and an increase in peripheral vascular resistance. Oxygen demand and supply for the Myocardium are normally balanced. Oxygen demand above quiescent needs of the Myocardium is determined by number of factors: Heart rate-the greater the frequency of contractions, the greater the oxygen demand. Myocardial wall tension is a function of both left ventricular systolic pressure and the ventricular radius [2]. The contractility of the heart-relates to the ...
