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

What should we done to patients
with hypertension ?

Goal of Treatment
9 November 2013 Seminar IDI Wilayah NTT 19
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
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
• 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
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
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
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
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
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)
-Inhibitor kimase secara signifikan menekan
pembentukan AT II
