Concomitant considerations in long-term antihypertensive treatment.

Area of Science:

• Cardiology
• Pharmacology
• Metabolic Medicine

Background:

• Hypertensive patients on medication still face higher risks for coronary events than normotensive individuals.
• The long-term metabolic effects of antihypertensive drugs on lipid profiles remain a concern.
• Understanding these effects is crucial for explaining partial therapeutic failure in hypertension management.

Purpose of the Study:

• To investigate the long-term metabolic effects of antihypertensive therapy on lipid metabolism.
• To assess the reversibility of these metabolic changes after discontinuing medication.
• To evaluate the impact of hydrochlorothiazide and atenolol on cholesterol and triglyceride levels over time.

Main Methods:

• Observational study of hypertensive patients undergoing long-term randomized antihypertensive treatment.
• Analysis of lipid metabolism parameters (total cholesterol, LDL-C, HDL-C, triglycerides) during and after treatment.
• Comparison of lipid levels before, during, and after cessation of hydrochlorothiazide and atenolol therapy.

Main Results:

• Hydrochlorothiazide increased total cholesterol, LDL-C, and triglycerides during treatment.
• Atenolol increased LDL-C and triglycerides while decreasing HDL-C during treatment.
• Discontinuation of both drugs led to significant improvements in lipid profiles, with effects persisting for over five years.
• Adverse metabolic alterations were reversible after medication cessation.

Conclusions:

• Long-term use of hydrochlorothiazide and atenolol is associated with persistent adverse effects on lipid metabolism.
• These metabolic disturbances are reversible upon discontinuation of the antihypertensive agents.
• Minimizing antihypertensive drug dosage may help mitigate adverse metabolic alterations and side effects.
