The Ageing Cardiovascular System Overview Why What changes occur Vascular Changes
Dixon, Darlene, Operations Manager and Program Director has reference to this Academic Journal, PHwiki organized this Journal The Ageing Cardiovascular System Jennifer Inglis 12th December 2006 Overview Why is it important to underst in addition to ageing of the cardiovascular system What changes in cardiovascular structure in addition to function are associated with ageing How might this affect our practice Why Prevalence of cardiovascular disease amongst elderly populations Its just my age, doctor Impact on our assessment in addition to treatment of elderly patients

What changes occur Vascular changes Postural changes Cardiac changes at rest Cardiac changes on exercise Vascular Changes Aorta in addition to large elastic arteries – wall thickness, dilation in addition to stiffening in mean systemic arterial pressure in most, but not all Systolic BP rises more than diastolic increasing chance of isolated systolic hypertension
Postural Changes Blunting of in HR Slowed baroreceptor response to postural change May be reduced vasoconstriction in response to reduced BP Increase the chance of postural hypotension Cardiac Changes at Rest Minor in HR CO output maintained by SV ejection of blood during late systole early diastolic filling rate EDV not – enhanced atrial contribution to LV filling beware AF, particularly if tachycardic
During exercise in maximum HR ( response to -adrenergic stimuli) in cardiac output – reduced by 30% between ages 20 in addition to 80 Maximum SV not reduced but maintained in different manner Frank Starling mechanism Frank Starling Mechanism EDV, due to: Longer diastolic interval ( HR) EF – amount of blood in LV at start of diastole Summary of changes
Some Practical Points Beware of increased risk of hypertension in addition to postural hypotension Elderly patients unlikely to tolerate tachycardia or AF as well as younger patients Caution with beta blockers In summary Ageing does alter the structure in addition to function of the cardiovascular system Changes more evident during exercise These effects may contribute to earlier decompensation when unwell in addition to remember your erect in addition to supine BPs!
