Insights
Enalapril and benazepril, used for hypertension, improved serum lipid profiles by increasing HDL-C and decreasing the total cholesterol/HDL-C ratio. These ACE inhibitors positively impacted the atherogenic ratio.
Area of Science:
- Cardiology
- Pharmacology
- Biochemistry
Background:
- Essential hypertension is a common condition requiring effective treatment.
- Serum lipid profiles are crucial indicators of cardiovascular risk.
- Antihypertensive medications can influence lipid metabolism.
Purpose of the Study:
- To compare the effects of four antihypertensive therapies on serum lipid parameters.
- To evaluate changes in high-density lipoprotein cholesterol (HDL-C) and the total cholesterol/HDL-C ratio.
- To assess the impact on the atherogenic ratio in patients with essential hypertension.
Main Methods:
- 80 patients with essential hypertension received enalapril, benazepril, Epitens, or isradipine for eight weeks.
- A control group of 10 hypertensive patients received a placebo.
- Serum lipid parameters, including HDL-C and the total cholesterol/HDL-C ratio, were measured post-therapy.
Main Results:
- Enalapril significantly increased HDL-C and decreased the total cholesterol/HDL-C ratio.
- Benazepril significantly decreased the total cholesterol/HDL-C ratio.
- Both enalapril and benazepril significantly improved the atherogenic ratio; isradipine showed a lesser improvement, while Epitens caused insignificant deterioration.
Conclusions:
- Angiotensin-converting enzyme inhibitors (enalapril, benazepril) demonstrate favorable effects on lipid profiles and the atherogenic ratio in hypertensive patients.
- Calcium channel blockers (isradipine) also show some benefit, though less pronounced.
- Diuretic combination therapy (Epitens) had minimal impact on electrolytes and a negative effect on the atherogenic ratio.
Abstract:
Serum lipids of 80 patients with moderately severe essential hypertension under four different antihypertensive therapies were compared to ten matched hypertensives on a placebo, after eight weeks of therapy. The results in the serum lipid parameters measured after therapy showed with enalapril a significant increase in high-density lipoprotein cholesterol (HDL-C) and a decrease in the total cholesterol/HDL-C ratio. With benazepril a significant decrease in the total cholesterol/HDL-C ratio was obtained. With the diuretic combination Epitens the effect on serum sodium and potassium was minimal. No significant changes were found in the lipoprotein profile following the administration of the placebo. Both angiotensin converting enzyme inhibitors (enalapril and benazapril) induced a significant improvement in the atherogenic ratio; as well as the calcium antagonist (isradipine), though to a less extent. The diuretic Epitens induced an insignificant deterioration of the atherogenic ratio.

Blood Studies for Cardiovascular System III: Serum Lipid Profile
Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...
