Hypertension / Hypotension Flashcards
What is the accepted change in creatinine with ACE/ARB use?
« 30%
What is the result of increase in increment of 20/10 mmHg of BP?
risk of dying from CVA or CAD at all ages –> doubles
What risk factor is responsible for an increased population burden of HFpEF?
Hypertension
What BP defines hypertensive crisis?
> 180 / 120 mmHg
and
evidence of end-organ damage
What are treatments of choice in hypertensive emergency?
What is the recommended reduction in BP in hypertensive emergency (in the absence of a high risk condition)?
- 1st hour –> Reduce BP by max 25%
- 2-6 hours –> 160 / 110 mmHg
- next 24-48 hours –> normal
What is the recommended BP reduction strategy?
- hypertensive emergency
- aortic dissection, severe preeclampsia/eclampsia, Pheochromocytoma crisis
- Preeclampsia/eclampsia, Pheochromocytoma
- 1st hour –> Reduce SBP to < 140 mmHg
- Aortic dissection
- 1st hour –> Reduce SBP to < 120 mmHg
Define resistant hypertension
- persistent HTN despite the use of:
- three antihypertensive agents at or near maximal dose
- of different classes
- at least one is a diuretic
- ► 1 month
- to allow to take effect
- three antihypertensive agents at or near maximal dose
Define stages of hypertension
- Normal = < 120 / 80
- Stage 1 = 130 - 139 / 80 - 89
- Stage 2 = ► 140 / ► 90
What is the recommendation for proceedig with ABPM or HBPM to differentiate?
- white coat hypertension
- HTN
- For patients not on drug therapy?
- BP > 130 / 80 but < 160 / 100 after 3 months of lifestyle modifications
What is the cutoff for HTN in a 24-hour ambulatory BP monitor?
125 / 85 mmHg
Define primary aldosteronism
- secondary hypertension cause
- due to aldosterone-secreting:
- adrenal adenoma
- adrenal hyperplasia
- Labs:
- metabolic alkalosis
- low potassium
- hypertension
- Diagnosis:
- aldosterone / renin ► 20
- with aldosterone ► 12
- aldosterone / renin ► 70
- with aldosterone ► 15
- and renin « 1
- aldosterone / renin ► 20
- Treatment
- spironolactone or
- eplerenone
Describe the relationship between HTN and CV disease
Log-Linear relationship
- SBP 20 mmHg and DBP 10 mmHg –>
- each associated with a doubling in the risk of death from stroke heart disease or other vascular disease
Describe differences in the following parameters between 80 year old and 20 year old?
- SBP
- DBP
- Aortic Pulse Wave Velocity
- Endothelial NO release
- SBP –> Increase
- DBP –> Decrease
- Aortic Pulse Wave Velocity –> Increase
- increased pulse pressure due to decreased aortic distensibility and
- increased arteriolar resistance
- Endothelial NO release –> Decrease
Define orthostatic hypotension secondary to autonomic dysfunction
- brief initial rise in HR with standing –>
- sustained fall in SBP ( > 20 mmHg) and DBP ( > 10 mmHg)
- without a compensatory rise in HR
