Q

We should avoid intensive BP targets in frail patients because…

Risks (orthostatic hypotension, falls) + treatment burden likely will outweigh benefits.
Time to benefit is ~2.5 years - is this applicable to patient?

19
Q

If there is no compelling indication for specific anti-HTN medications, we should choose…

A

Agents indicated for isolated systolic hypertension
ARB, TZD, DHP-CCB

20
Q

HTN medications for diabetes include…

A

ACE/ARB for microalbuminuria - DHP-CCB > TZD 2nd line
No microalbuminuria = ACE/ARB, DHP-CCB, or TZD’s

21
Q

HTN medications for CAD include…

A

ACE/ARB - beta-blocker or CCBs for patients with stable angina

22
Q

HTN medications for HF include…

A

Remember quadruple therapy - ACE/ARB or ARNI, Beta-blocker, MRA, SGLT2i

23
Q

HTN medications for past-stroke or TIA include…

A

ACE/ARB, TZD combination

24
Q

HTN medications for non-diabetic CKD with proteinuria include…

A

ACE/ARB, diuretics as additive therapy

25
Q

If our patients have persistently high blood pressure despite treatment, we should evaluate…

A

Adherence
Secondary causes of hypertension (medications - NSAID’s)

26
Q

With diuretics, we need to monitor…

A

Electrolytes - specifically potassium + sodium
TZD’s may increase gout risk
Watch for orthostatic hypotension + worsening urinary urgency/incontinence

27
Q

With ACEI/ARB’s we should monitor…

A

Electrolytes - potassium
SCr
Sitting + standing BP
Angioedema (rare)

Generally well tolerated

28
Q

CCB’s can cause or exacerbate…

A

Peripheral edema, especially at higher doses
Non-DHP CCB likely to be constipating

Can split dose or take at nighttime to minimize

29
Q

Non-DHP CCB’s should be avoided in…

A

HFrEF
Combination with beta-blockers

30
Q

Non-DHP CCB’s may be useful to…

A

Control HR in AFib

31
Q

Beta-blockers are not recommended as…

A

First line anti-HTN medications for adults 60+

32
Q

Beta-blockers are recommended in older adults if compelling indications exist. This includes…

A

Post-MI
HFrEF
Rate control in AFib

May be used as add-on therapy for HTN

33
Q

With beta-blockers we need to monitor…

A

Fatigue
Decreased exercise tolerance

Contribution to degree of frailty?

34
Q

Statin use for secondary prevention of CV events…

A

Should be started/continued regardless of age - mild-moderate frailty
Benefits generally outweigh risks

Time to benefit ~2 years

35
Q

Statin use for primary prevention of CV events after 75 years of age…

A

Lack of evidence to support who should receive statin therapy for primary prevention of CV events

Shared decision making regarding CV risk factors, functional status, medication burden, AE’s from statin

Generally benefits > risks but consider the individual

36
Q

Evidence for high vs. moderate intensity statin therapy indicates…

A

High-dose statins for high-risk patient groups (Post-MI, post-stroke) - however, more susceptible to statin AE’s, but benefit > risk

Moderate-dose statins may be preferred in older adults especially outside of acute post-event period (1 year)

37
Q

Do other cholesterol medications have a role in older adults?

A

Limited role
PCSK-9 inhibitor for familial hypercholesterolemia
Fibrates in severe hypertriglyceridemia
Ezetimibe - limited evidence for improving CV outcomes with/without statins

Consider deprescribing if appropriate to decrease pill burden

38

Previous ACS or PCI
Coronary artery bypass grafting

Signs, symptoms, complications of inadequate blood flow to heart muscle due to atherosclerosis

A

Reducing CV risk post-MI - titrated to resting HR of ~60 BPM

44
Q

Beta-blockers can be re-evaluated post-MI based on…

A

Symptoms and comorbidities

Indefinitely for HFrEF, can continue if angina symptoms continue or for AFib requiring rate control

Poorly tolerated = re-evaluate of 3+ years post-MI

45
Q

Short-acting nitroglycerin can be used for…

A

Rescue
Prophylactically, prior to activities which provoke symptoms

Always good to have just in case

46
