The cardiovascular system of the elderly is characterised by (i) an increased characteristic impedance of the big vessels, without hypertension; (ii) a cardiac index unchanged at rest and during submaximal exercising, despite a diminished
VO2 max ; (iii) a diastolic dysfunction with reduced rapid early filling (E wave at echo) and enhanced atrial systole (A wave); (iv) benign arrhythmias; (v) a reduced coronary reserve and an increased sensitivity to ischemia; (vi) an efficacy of converting enzyme inhibitors remaining unchanged, despite an altered renin–agiotensin system.
