Top 10 HTN RX Problems

10. Lack of Public Awareness 68%

9. Lack of Provider Awareness - Systolic BP

8. Lack of Treatment 54%

7. Lack of Provider Awareness Lifestyle RX

6. Providers / Patients - office BP is higher

5. Thought that BP rise with age is not a risk

ALLHAT Conclusions

Amlodipine (representing CCB), lisinopril (representing ACE-I) and chlorthalidone (representing thiazide-type diuretics) were comparable in preventing major coronary events or increasing overall survival.

Although chlorthalidone did not differ from amlodipine in overall CVD event prevention, it was superior to amlodipine in preventing heart failure.

Page 21: Hypertension: New Trials – Best Treatments Karen Moncher, MD Assistant Professor University of Wisconsin School of Medicine and Public Health

ALLHAT Conclusions

Chlorthalidone was superior to lisinopril in preventing aggregate CV events, principally stroke, HF, angina, and coronary revascularization

Chlorthalidone was superior to doxazosin (representing alpha-blockers) in preventing CV events, including both HF and other CVD.

Page 22: Hypertension: New Trials – Best Treatments Karen Moncher, MD Assistant Professor University of Wisconsin School of Medicine and Public Health

Overall Conclusions

ALLHAT

Because of the effectiveness of thiazide-type diuretics in preventing one or more major forms of CVD and their lower cost, they should be the drugs of choice for first-step antihypertensive drug therapy, unless there are other compelling indications.

Sodium Recommendations

No Added Salt (2400 mg/day)Hypertension, impaired liver function, cardiovascular disease, cardiac failure, and acute and chronic renal failure.

1000 mg* (45 mEq)Cirrhosis of the liver, pulmonary edema, moderate to severe cardiac failure, acute and chronic liver failure.

*For short term use only due to decreased palatability and adherence.

Patients Undergoing Surgery

• Those not on prior drug therapy may be best treated with cardio-selective-blockers before and after surgery.

• Those with controlled blood pressure should continue medication until surgery and begin as soon after surgery as possible.

Page 48: Hypertension: New Trials – Best Treatments Karen Moncher, MD Assistant Professor University of Wisconsin School of Medicine and Public Health

Using Thiazide Diuretics

• Can use either HCTZ or chlorthalidone• Use only 12.5 - 25 mg. Daily• Higher doses no more effective, and have more

side effects and electrolyte problems• Do not affect lipids or glucose significantly• Do result in LVH regression• Synergistic with all other classes of medications

– reduce plasma volume

Page 49: Hypertension: New Trials – Best Treatments Karen Moncher, MD Assistant Professor University of Wisconsin School of Medicine and Public Health

Gout

• Diuretics can increase serum uric acid levels.

• Diuretics should be avoided in patients with gout.

• Diuretic-induced hyperuricemia does not require treatment in the absence of gout or urate stones.

Page 50: Hypertension: New Trials – Best Treatments Karen Moncher, MD Assistant Professor University of Wisconsin School of Medicine and Public Health

Using ACE Inhibitors

• Patients with:– Diabetes Mellitus– Nephropathy / Albuminuria– Post- MI– Congestive Heart Failure

• Once daily (except captopril)• Use ARB if cough develops• Use with care if hyperkalemia / CRF

Angiotensin Receptor Blocker and Hypertension

LIFE Trial:• Losartan vs. Atenolol (w / HCTZ if needed) for

9193 patients: Hypertension aged 55-80 years• BP decrease 28/9 mmHg both groups• CVD mortality*: 8.7 vs 16.9 (46% reduction)• Stroke*: 10.6 vs 18.9 (40% reduction)• New DM*: 12.6 vs 20.1 (38% reduction)• Total Mortality*: 21.2 vs 30.2 (54% reduction)

Uses of Calcium Blockers

• Isolated Systolic HTN / Elderly

• African Americans w/better response

• CHD – Angina

• HTN – resistant – especially with a diuretic

• Exercise induced HTN

• Peripheral arterial disease

• Migraine + HTN

Page 53: Hypertension: New Trials – Best Treatments Karen Moncher, MD Assistant Professor University of Wisconsin School of Medicine and Public Health

Calcium Blockers

A calcium blocker is not a calcium blocker:• AV node inhibitors / modest vasodilators:

– Verapamil– Diltiazem

• Vasodilators: Dihydropyridines– Amlodipine (Norvasc)– Felodipine (Plendil)*Nifedipine: also negative iontrope / adrenergic

Not at Goal Blood Pressure (< 140/90 mm Hg)

No response or troublesome side effects

Inadequate response but well tolerated

Substitute another drug from different class

Add second agent from different class (diuretic

if not already used)

Causes for InadequateResponse to Drug Therapy

• Nonadherence to therapy / lifestyle

• Alcohol use

• Volume overload

• ***Failure to add a diuretic***

• Drug-related causes

• Non-steroidal anti-inflammatories

• Identifiable causes of hypertension

Overview

• Epidemiology • Clinical Trials and Trends

– “All things old become new again”

• Management Guidelines– Compelling reasons for treatment– Management based on patient problems and pharmacology

• Patient Adherence

Page 57: Hypertension: New Trials – Best Treatments Karen Moncher, MD Assistant Professor University of Wisconsin School of Medicine and Public Health

Guidelines for ImprovingAdherence to Therapy

• Close follow-up 4 – 6 weeks

• Prescribe long-acting / once daily medications

• Adjust therapy to minimize adverse affects

• Use synergistic medications

• Utilize other health professionals

• Consider using nurse case management

• Involve the patient in self-care

Page 58: Hypertension: New Trials – Best Treatments Karen Moncher, MD Assistant Professor University of Wisconsin School of Medicine and Public Health

Advantages of Self-Measurement

• Identifies “white-coat hypertension”

• Assesses response to medication

• Improves adherence to treatment

• Potentially reduces costs

• May confirm HTN to patient and may provide lower readings than those recorded in clinic

Lifestyle Modifications

For Prevention and Management

• Lose weight if overweight.

• Limit alcohol intake.

• Increase aerobic physical activity.

• Reduce sodium intake.

• DASH diet*

For Overall and Cardiovascular Health

• Maintain adequate intake of calcium and magnesium.

• Stop smoking.

• Reduce dietary saturated fat and cholesterol.

• Increase fruits/vegetables/fiber and healthy oils

Page 63: Hypertension: New Trials – Best Treatments Karen Moncher, MD Assistant Professor University of Wisconsin School of Medicine and Public Health

Children and Adolescents

• Blood pressure at 95th or higher percentile is considered elevated.

• Lifestyle modifications should be recommended.

• Drug therapy should be prescribed for higher levels of blood pressure.

• Attempts should be made to determine other causes of high blood pressure and other cardiovascular risk factors.
