Insights
This study investigated irbesartan for obese patients with high blood pressure. It found irbesartan effective in reducing blood pressure and improving cardiovascular and kidney health in this high-risk group.
Area of Science:
- Cardiology
- Nephrology
- Endocrinology
Background:
- Obesity and hypertension frequently coexist, increasing cardiovascular and renal risks.
- Overweight and obese individuals have a high prevalence of hypertension (43%) and associated comorbidities like diabetes, coronary heart disease, and nephropathy.
- Elevated cardiac risk is a significant concern in overweight and obese hypertensive patients.
Purpose of the Study:
- To evaluate the efficacy, tolerability, and safety of irbesartan in overweight and obese hypertensive patients.
- To compare outcomes between obese and nonobese patients receiving irbesartan.
- To assess the impact of irbesartan on blood pressure reduction, (micro)albuminuria, and overall patient risk profile.
Main Methods:
- A prospective medical care study (BIG) conducted in Germany.
- Obese hypertensive patients received irbesartan (monotherapy or combination with hydrochlorothiazide) for 3 months.
- Key variables assessed included drug utilization, blood pressure changes, responder/normalization rates, (micro)albuminuria, risk profile changes (e.g., SCORE), and tolerability.
Main Results:
- The study is ongoing and expected to yield data on irbesartan's effectiveness.
- Comparisons will be made between obese and nonobese patient groups.
- Outcomes will focus on blood pressure reduction, renal protection, cardiac risk mitigation, and drug tolerability.
Conclusions:
- The study aims to provide new insights into irbesartan's role in managing hypertension in overweight and obese individuals.
- Findings are anticipated to inform clinical practice regarding the use of irbesartan for pressure reduction and organ protection.
- The research is expected to enhance understanding of irbesartan's benefits in a high-risk patient population.
Abstract:
Patients with high blood pressure are often overweight or even obese. Conversely, some 43% of overweight and obese patients suffer from hypertension. Diabetes (16.7%), coronary heart disease (15.0%) and nephropathy (7.8%) are common additional findings. The cardiac risk in these patients is thus appreciably elevated. Currently, a prospective medical care study "Best practice with irbesartan in overweight and obese patients" (BIG) - is being conducted throughout Germany. In this study obese hypertensive patients of general practitioners are receiving the AT1 blocker irbesartan, as monotherapy or in fixed combination with the diuretic hydrochlorothiazide over a period of 3 months. Obese patients and nonobese patients are compared with regard to the following variables: drug utilization, blood pressure decrease, responder rates, normalization rates, decrease in the number of patients with (micro)albuminurea, changes in patient risk profile (e.g. after SCORE), and tolerability. The study is expected to provide new information on the efficacy, tolerability and safety of irbesartan in regard to pressure reduction and its protective effect on the kidneys and heart in overweight patients.

Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
