Increased enzymatic activity of renin and hyperlipidemia

The role of statins in endothelial dysfunction in hypertension

PURPOSE OF REVIEW

Hypertension and dyslipidemia frequently coexist, and endothelial dysfunction is associated with the pathophysiology of both atherosclerosis and hypertension. Evidence is convincing for an overlapping role of oxidative stress, renin-angiotensin system activation, and dyslipidemia in the genesis of endothelial dysfunction.

RECENT FINDINGS

Ample experimental and human data suggest that common cellular pathways are involved in the pathogenesis of hypertension, increased vascular resistance, and plaque formation. Multiple interventions such as dietary modification, exercise, antioxidants, and antihypertensive drugs improve endothelial dysfunction in hypertension. Statin drugs are a cornerstone of dyslipidemia therapy. Studies have demonstrated that statins correct endothelial function and vascular stiffening and may be useful in reducing blood pressure to target levels.

SUMMARY

Statins may be a useful adjunct in the treatment of hypertension in patients with dyslipidemia and possibly those with normal cholesterol levels.
