12. How to prevent CV event?
• Life style modification
• Adherence concept
• Early and agresive BP lowering
• Treatment to target levels
• Drug choice

13. Life Style Modification

14. Adherence Concept
• The best adherence is in ARB treatment
• Good adherence reduces CV risks
• Fully adherence only in 30% pts after 1 year
• Poor adherence and compliance not only due
to patients and side effect, but also physician
and policy service

and lipid-lowering therapy. Arch Intern Med. 2005;165:1147-1152

15. Early and Aggressive BP Lowering
• TROPHY trial :
– Pre-Hypertension pts
– Early intervention reduces CV risks
– High BP related with CVD risks
• Framingham Study :
– 31% patients stroke with normal and high normal
hypertension
• VALUE Study :
– Benefit of the study due Rapid reduction and BP
control in the beginning
 The Earlier The Better

16. Treatment to Target Levels
• The Lower the Better?

28. • Purpose of study : to evaluate the effect of treatment with the
angiotensin I type 1 receptor blocker irbesartan on maintaining sinus
rhythm after conversion from persistent atrial fibrillation
• Design : prospective, randomized trial
• Number of participants : 154
• Interventions :
– Group I : amiodarone 400mg/day
– Group II : amiodarone 400mg/day + irbesartan 150-300mg/day
• Follow-up period : 12 months
Circulation. 2002;106:331-336.

29. Conclusion :
Patients treated with amiodarone plus irbesartan had a
lower rate of recurrence of atrial fibrillation than did
patients treated with amiodarone alone.
Results :
After 2 months of follow-up in the
intention-to-treat analysis, the group
treated with irbesartan had fewer
patients with recurrent atrial fibrillation
(Kaplan-Meier analysis, 84.79% versus
63.16%, P=0.008). The Kaplan-Meier
analysis of time to first recurrence
during the follow-up period (median
time, 254 days [range, 60 to 710]) also
showed that patients treated with
irbesartan had a greater probability of
remaining free of atrial fibrillation
(79.52% versus 55.91%, P0.007).
Circulation. 2002;106:331-336.

30. • Purpose of study : to evaluate whether irbesartan would
reduce the risks of cardiovascular events among patients
with atrial fibrillation
• Design : double-blind, randomized trial
• Number of participants: 9.016 patients
• Interventions :
– Group I : irbesartan at a target dose of 300 mg once daily
– Group II : double-blind placebo
• Follow- up time : mean 4.1 years

41. • Results :
The second coprimary outcome occurred at a rate of 7.3%
per 100 person-years among patients receiving irbesartan
and 7.7% per 100 person-years among patients receiving
placebo (hazard ratio, 0.94; 95% CI, 0.87 to 1.02; P =
0.12). The rates of first hospitalization for heart failure (a
prespecified secondary outcome) were 2.7% per 100
person-years among patients receiving irbesartan and 3.2%
per 100 person-years among patients receiving placebo
(hazard ratio, 0.86; 95% CI, 0.76 to 0.98).
• Conclusion :
In patients with atrial fibrillation, irbesartan was
associated with a reduction in heart failure and
hospitalizations for cardiovascular causes.

42. Pengaruh Irbesartan Terhadap Ketebalan Ventrikel Kiri
vs Atenolol:
The CardioVascular Irbesartan Project

43. The CardioVascular Irbesartan Project
• Tujuan : membandingkan pengaruh irbesartan
vs atenolol terhadap LVH (left
ventricular hypertrophy).
• Penelitian : acak, tersamar ganda, multisenter
• Jumlah pasien: 240 pasien dengan hipertensi esensial
• Terapi :
– Kelompok I diberikan irbesartan
– Kelompok II diberikan atenolol
• Lama penelitian: 18 bulan

44. • Hasil penelitian:
Pada bulan ke 6 dan 18, penurunan massa ventrikel kiri/ (LVM, Left
Ventrikular Mass) dan perbaikan kriteria EKG untuk hipertrofi
ventrikel kiri (LVH) hanya ditemukan pada pasien yang diterapi
menggunakan irbesartan
• Kesimpulan penelitian ini:
Terapi hipertensi dengan Irbesartan menghasilkan
pengurangan yang bermakna terhadap kriteria EKG untuk
LVH, dengan kata lain terjadi penurunan penebalan
ventrikel kiri.
Pemberian atenolol tidak mengurangi ketebalan ventrikel
kiri secara bermakna pada pemeriksaan EKG.
