Differential effects of antihypertensive drugs on hypertension: associated risk factors
1Medizinische Universitätspoliklinik Inselspital, Bern, Switzerland.
Insights
Preventing coronary heart disease is key in hypertension management. Antihypertensive drugs should address risk factors like dyslipidemia and glucose intolerance, with ACE inhibitors showing benefits for diabetic patients.
Area of Science:
- Cardiology
- Nephrology
- Endocrinology
Background:
- Hypertension management aims to prevent coronary heart disease.
- Key risk factors include dyslipidemia, hyperinsulinemia, glucose intolerance, obesity, and left ventricular hypertrophy.
- Metabolic alterations often precede hypertension in genetically predisposed individuals.
Purpose of the Study:
- To evaluate the role of antihypertensive treatment in managing cardiovascular risk factors.
- To compare the efficacy of different antihypertensive agents, particularly in diabetic patients.
- To emphasize individualized treatment strategies considering drug profiles.
Main Methods:
- Review of existing literature on antihypertensive therapies and their impact on cardiovascular risk factors.
- Analysis of the benefits of specific drug classes, such as ACE inhibitors, beta blockers, and thiazide diuretics.
- Consideration of patient-specific factors in treatment selection.
Main Results:
- Angiotensin-converting enzyme (ACE) inhibitors demonstrate superiority in normotensive or borderline hypertensive diabetic patients due to antiproteinuric effects and improved glomerular filtration rate.
- ACE inhibitor treatment in diabetic nephropathy reduces mortality and the need for dialysis or transplantation.
- Beta blockers and thiazide diuretics remain standard for non-diabetic patients, while newer drugs require further study for long-term outcomes.
Conclusions:
- Individualized antihypertensive therapy is crucial, considering metabolic, cardiac, and renal profiles.
- ACE inhibitors and calcium antagonists are preferred for hypertensive diabetics due to favorable effects on cardiovascular and renal risk factors.
- Further research is needed on the long-term impact of newer antihypertensive drugs on morbidity and mortality in non-diabetic populations.
Abstract:
The primary aim of the management of hypertension should be to prevent coronary heart disease. Antihypertensive treatment should have a beneficial effect on the risk factors associated with coronary heart disease, particularly hypertension, dyslipidemia, hyperinsulinemia, and/or glucose intolerance. Other important risk factors include central obesity, left ventricular hypertrophy, hypokalemia, and smoking. In patients genetically predisposed to essential hypertension, metabolic alterations characterized by insulin resistance, hyperinsulinemia, and dyslipidemia tend to occur already before the development of hypertension, obesity, or redistribution of body fat. In the treatment of normotensive or borderline hypertensive diabetic patients, angiotensin-converting enzyme (ACE) inhibitors have shown superiority to other agents due to their antiproteinuric effect and their beneficial influence on the glomerular filtration rate. ACE inhibitor treatment of patients with overt diabetic nephropathy has been reported to reduce the risk of mortality and the need for dialysis or transplantation. Beta blockers and thiazide diuretics are still the 'gold standard' of antihypertensive therapy in non-diabetic patients, as they offer at least some prognostic benefit, while the influence of the newer antihypertensive drugs on morbidity and mortality in these patients is not yet known. Nevertheless, since practicing physicians have to treat patients rather than statistical numbers, the current trend towards a more individualized selection, including the newer antihypertensive drugs with consideration of their metabolic, cardiac, and renal action profile, is also difficult to rebut. ACE inhibitors and most calcium antagonists have already evolved as the preferred drugs for the treatment of hypertension in diabetics due to their favorable effects on some of the cardiovascular and renal risk factors.
