Improving adherence with amlodipine/atorvastatin therapy: IMPACT study

Area of Science:

• Cardiology
• Public Health
• Pharmacology

Background:

• Hypertension and dyslipidemia are prevalent, particularly uncontrolled in the United States.
• Indigent African Americans with high-risk, resistant hypertension and dyslipidemia face significant cardiovascular risks.
• Effective management strategies are crucial for this high-risk population.

Purpose of the Study:

• To assess the efficacy of once-daily combination therapy for blood pressure (BP) and dyslipidemia in indigent African Americans.
• To evaluate the impact of home BP monitoring on achieving clinical BP and lipid goals.
• To determine if treatment goals can be met in this specific demographic.

Main Methods:

• A 6-month randomized trial comparing home and clinic BP monitoring group with usual care.
• Participants: middle-aged, indigent African Americans with high-risk, resistant hypertension and dyslipidemia.
• Intervention: Once-daily combination therapy, with BP titration based on home and clinic measurements.

Main Results:

• Both groups showed significant reductions in BP, total cholesterol, and LDL cholesterol (P<.0001).
• BP control rate reached 43.5%, exceeding the 2004 national rate of 35%.
• Improved LDL control rates were observed, indicating enhanced lipid management.

Conclusions:

• Once-daily combination therapy is effective in managing hypertension and dyslipidemia in indigent African Americans.
• Home BP monitoring can improve the achievement of clinical BP and lipid goals in this population.
• Cardiovascular risk reduction is attainable through effective BP and lipid management in high-risk individuals.
