ReferenceStudy drugsStudy population and designStudy durationFindings

Cacciatore et al. [98]Enalapril 20 mg/day versus zofenopril 30 mg/day, 36 patients with newly diagnosed mild hypertension, randomized trial5 years↑ EPC count  
No difference between groups  
↓ intima media thickness

Sun et al. [99]Perindopril 4 mg/day versus placebo68 patients with acute myocardial infarction and T2DM28 days after PCI↑ EPC count  
↑ VEGF  
↑ SDF-1α
↑ LVF  
↓CV mortality in the perindopril group

Min et al. [100]Ramipril 5 mg/day36 nondiabetic patients with acute myocardial infarction4 weeks↑ EPC count 1.5-fold after 1 week, 2.5-fold after 4 weeks  
↑ EPC proliferation, migration, and adhesion

Cangiano et al. [101]Perindopril 10 mg/day versus valsartan 320 m/day Patients with acute coronary syndromes  
16 receiving perindopril  
17 receiving valsartan  
20 healthy controls
30 days↑ EPC mobilization, ↑ VEGF in the perindopril group  
No effects found for valsartan

Porto et al. [102]Ramipril 5 mg/day versus telmisartan 80 mg/day42 patients with acute coronary syndrome, randomized trial20 days after PCI↑ EPC count in both groups Telmisartan had a more profound anti-inflammatory effect

Pelliccia et al. [103]Telmisartan 40 mg/day versus placebo40 normotensive patients with CAD, randomized trial4 weeks↑ EPC count  
↑ FMD

Bahlmann et al. [95]Olmesartan 40 mg/day versus placebo, double-blind RCT  
Irbesartan 300 mg/day, open trial
18 patients with T2DM randomized to olmesartan or placebo  
20 patients with T2DM receiving irbesartan
12 weeks↑ EPC count with both olmesartan and irbesartan

Tan et al. [104]Losartan 100 mg/day↑ EPC count  
↑ FMD

Suzuki et al. [105]Losartan 50 mg/day versus trichlormethiazide 4 mg/day36 patients with hypertension randomized to losartan or trichlormethiazide  
Control group: 18 normotensive patients
4 weeks↑ EPC count with losartan  
Hypertensive patients had a lower EPC count in comparison to normotensive patients

Kampoli et al. [106]Pioglitazone (15 m/day) versus perindopril (4 mg/day)50 patients with T2DM, randomized trial1 monthNo effect on EPC

Sugiura et al. [96]Nifedipine SR 20 mg/day versus placebo37 hypertensive patients with stage I hypertension, randomized trial4 weeks↑ EPC count  
↑ EPC differentiation migration, resistance to oxidative stress  
↑ FMD

de Ciuceis et al. [97]Barnidipine 20 mg/day versus hydrochlorothiazide 25 mg/day29 hypertensive patients with mild essential hypertension, randomized trial6 months↑ EPC count with barnidipine  
No difference in RR reduction observed between drugs
