Treatment of hypertension

is still an unsolved issue

Menurut Riskesdas tahun 2007, prevalensi hipertensi di Indonesia sebesar 32,2%4

Sekitar 20% populasi dewasa di dunia menderita hipertensi1

Namun, hipertensi terkontrol hanya didapatkanpada 36,8% pasien1-3

Di AS, hipertensi ditemukan pada 30% penduduk dewasa1-3

Goal of Treatment

9 November 2013 Seminar IDI Wilayah NTT 19

Page 20: Hypertension

Goal of Hypertensive Treatment

To achieve the maximum reduction in the total

risk of cardiovascular, cerebrovascular,

nephrosclerosis morbidity and mortality

( WHO-ISH 1999 )

9 November 2013 Seminar IDI Wilayah NTT 20

Page 21: Hypertension

Goals of treatment

JNC VII ( 2003 ) :

• < 140 / 90 mmHg or < 130 / 80 mmHg for those

with Diabetes or Chronic Kidney disease.

• Achieve SBP goal especially in persons >50

years of age. 9 November 2013 Seminar IDI Wilayah NTT 21

Page 22: Hypertension

• At least below 140 / 90 mmHg ( lower

values if tolerated )

• Below 130 / 80 mmHg in Diabetics.

• Keeping in mind, however, that systolic

below 140 mmHg may be difficult to

achieved in elderly (more flexible )

Principles of drug treatment

Independent of particular drugs

• Low doses to initiate therapy

• Drugs combination to maximize hypotensive

efficacy while minimizing side effects.

• Changing to a different drug class if there is very

little response or poor tolerability

• Long acting drugs : provide greater protection

against target organ damage

HYPERTENSION IN SPECIAL GROUPS

Hypertension and diabetes mellitus

ACEIs are the agents of choice for patients with diabetes without proteinuria

ACEIs or ARBs are the agents of choice for patients with diabetes and proteinuria

Beta-blockers, diuretics or CCBs may be considered if either of the above cannot be used.

Hypertension and the metabolic syndrome

Beta-blockers and thiazide diuretics have the potential to increase the incidence of new onset diabetes and this should be taken into consideration when choosing drugs for patients diagnosed with the metabolic syndrome.

9 November 2013 Seminar IDI Wilayah NTT 44

Page 44: Hypertension

HYPERTENSION IN SPECIAL GROUPS

Hypertension and non-diabetic renal disease

Target BP should be <130/80 mmHg for those with proteinuria of <1g/24 hours and <125/75 mmHg for those with proteinuria of >1g/24 hours

ACEIs are recommended as initial anti-hypertensive therapy

ARBs should be used in patients intolerant to ACEIs

Dietary salt and protein restriction is important

Concurrent diuretic therapy is useful in patients with fluid overload

Non-dihydropyridine CCBs can be added on if the BP goal is still not achieved

Jadi . . . REKOMENDASI KDIGO 2012

Sudah mulai di balik rekomendasinya, biasanya setiap guideline : ACE or ARB. Tapi dalam Guideline terbaru KDIGO 2012 sudah di balik pilihannya : ARB atau ACE

Page 47: Hypertension

Hypertension and cardiovascular disease

Hypertensive patients with LVH should receive an ARB as the first line treatment

In CHD, beta-blockers, ACEIs and long acting CCBs are the drugs of choice

Beta-blockers, ACEIs and aldosterone antagonists should be considered in patients with CHD especially in post myocardial infarction and when associated with LV dysfunction

Beta-blockers need to be cautiously used in patients with peripheral vascular disease. They are contraindicated in patients with severe PVD

Diuretics, ACEIs, beta-blockers, ARBs and aldosterone antagonists are drugs of choice for heart failure

9 November 2013 Seminar IDI Wilayah NTT 48

Page 48: Hypertension

HYPERTENSION IN SPECIAL GROUPS

Hypertension and stroke

Lowering blood pressure is the key to both primary and secondary prevention of stroke

In acute stroke, lowering BP is best avoided in the first few days unless hypertensive emergencies co-exist

In primary prevention, a CCB-based therapy is preferred

In secondary prevention, the benefits of BP lowering is seen in both normotensive and hypertensive patients

ACEI- or ARB- based treatment is preferred in secondary prevention

9 November 2013 Seminar IDI Wilayah NTT 49

Page 49: Hypertension

HYPERTENSION IN SPECIAL GROUPS

Hypertension in the elderly

Isolated Systolic hypertension is particularly common in the elderly and should be recognized and treated

Standing BP should be measured to detect postural hypotension

Decreasing dietary salt intake is particularly useful

When prescribing drugs, remember to start low and go slow

9 November 2013 Seminar IDI Wilayah NTT 50

Page 50: Hypertension

HYPERTENSION IN SPECIAL GROUPS

Hypertension in pregnancy

Pregnant women who are at high risk of developing preeclampsia should be referred to the obstetrican for screening and commencement of prophylaxis with aspirin

Prophylactic calcium supplementation from early pregnancy is beneficial and recommended

Pregnant women with hypertension should be referred to the obstetrician for further management

The antihypertensives of choice are methyldopa and labetalol

Oral nifedipine 10mg stat dose can be used to rapidly control BP in an acute hypertensive crisis prior to transfer to hospital

Kelemahan ACE-i

• Intoleransi ACEi

– SPICE (Study of Patients Intolerant of Converting Enzyme Inhibitors)

• 20% pasien CHF tidak toleran terhadap ACE-i

– Pada HOPE trial, 25% pasien pada grup perlakuan menghentikan pengobatan ACE-i dengan alasan batuk, angioedema, dan hipotensi

– Pada studi pasien DM berusia >65 tahun, 38% pasien menghentikan pengobatan karena efek samping ACE-i. Bila agen pengobatan diganti dengan ARB, hanya 8% yang menghentikan terapi (Bogaisky, Allu,

Messenger, 2008)

Penekanan produksi AT II tidak lengkap

-Terdapat 2 jaras yang memproduksi AT II

pada miokardium

-ACE-i tidak memperlihatkan efek

penekanan AT II jangka panjang (Kirlin PC,

et al. 1995)
