真实世界研究(杜文民)_PPT幻灯片

• Target BP was achieved in 66.1% of patients in the total population, 68.3% of untreated patients, 68.4% of patients uncontrolled with monotherapy, and 59.9% of patients inadequately managed with combination therapy. In 161 patients with SBP >180 mmHg at baseline (newly diagnosed: n = 50; uncontrolled on monotherapy: n = 53; inadequately managed on combination therapy: n = 58), BP was reduced by 63.2 +/- 32.5/29.0 +/- 21.9 mmHg (p < 0.0001) at day 60. The fixed combination was safe and well tolerated. All 1175 patients completing the 60-day study (94%) adhered to their treatment regimen.

• Fixed combination perindopril 4 mg/amlodipine 5 mg once daily for 60 days. The primary outcomes were the mean change in BP from baseline and the proportion of patients achieving adequate BP control (</=140/90 mmHg, or </=130/80 mmHg in patients with diabetes mellitus) in the intent-to-treat (ITT) population. Secondary analyses included incidence of adverse events (ITT) and treatment adherence rate (completers).

关于真实世界研究的结论
• RCT应该用于评价有效性（efficacy ），而 RWS用于决定效应性（effectiveness ）
• Adults aged 40-70 years with newly diagnosed/untreated stage 2 hypertension (BP >/=160/100 mmHg), hypertension uncontrolled with monotherapy (BP >140/90 mmHg), or hypertension inadequately managed with another combination therapy.
• STRONG(Safety & efficacy analysis of coversyl amlodipine in uncontrolled and Newly diagnosed hypertension)
• Management of Hypertension with the Fixed Combination of Perindopril and Amlodipine in Daily Clinical Practice: Results from the STRONG Prospective, Observational, Multicenter Study.
• Bahl VK, Jadhav UM, Thacker HP • Am J Cardiovasc Drugs. 2009;9(3):135-42
• This was a naturalistic, real-world, clinic-based, outpatient study involving 336 general practitioners/primary care physicians in 65 cities in India.
• RWS 提供RCT没有的补充资料 • RWS 能够作为属于药物流行病学重要的工

• In total, 1250 patients comprised the ITT population: 32.6% with newly diagnosed hypertension; 40.5% with hypertension uncontrolled with monotherapy; and 26.9% with hypertension inadequately managed with another combination therapy. Mean SBP/DBP decreased significantly from baseline (167.4 +/- 15.2/101.4 +/- 9.1 mmHg) over 60 days (-41.9 +/- 34.8/-23.2 +/- 21.8 mmHg; p < 0.0001).
