Q
Effects of aging on cardiovascular structure and function (4)
A
Increased vascular and myocardial stiffness
Decreased ß-adrenergic and baroreceptor responsiveness
Impaired sinus node function
Impaired endothelial function
Net effect = large reduction in cv reserve
2
Q
Clinical implications of the effects of aging on the cardiovasc system (4)
A
Increased SBP and pulse pressure
Increased prevalence Afib,HF esp with preserved LV function
Increase prevalence of bradyarrythmias and “sick sinus syndrome”
Worse prognosis associated with all CV disease
