High serum cholesterol has been frequently reported in patients with arterial hypertension in whom it might influence the blood pressure control. The aim of this study was to compare the extent of blood pressure changes in 41 patients with hypertension and hypercholesterolemia, taking antihypertensive drugs and treated for 3 months with statins (HC-S; pravastatin or simvastatin) and compared with matched controls with high (HC-D; 44) or normal serum cholesterol (NC-D; 45) undergoing antihypertensive treatment combined with dietary treatment alone. After 3 months of follow-up, a greater reduction of systolic (SBP) and diastolic (DBP) blood pressure values was observed in HC-S patients (ASBP/DBP, -11.3 +/-3/-10.6 +/- 2%) when compared with both HC-D (deltaSBP/DBP, -6.6 +/- 2/-6.1 +/- 2%; p < 0.05) and NC-D (deltaSBP/DBP, -6.9 +/- 2/-6.8 +/- 1.5%; p < 0.05). In statin-treated patients, a slight linear relation has been found between the percentage changes in DBP and those in plasma total cholesterol (R = 0.37, p = 0.043), whereas no relation was found with SBP changes (R =0.11; p = 0.35). In conclusion, the results of this study demonstrate that the use of statins in combination with antihypertensive drugs can improve blood pressure control in patients with uncontrolled hypertension and high serum cholesterol levels. The additional blood pressure reduction observed in patients treated with statins is clinically relevant and only partially related to the lipid-lowering effect.

In this study of tinnitus in patients receiving antihypertensivetherapy, tinnitus was found in 17.6% of patients. Tinnitus was associated with the use of diuretics and with low SBP. Further studies are needed.

Hypertension and high serum cholesterol levels are two of the most relevant risk factors for cardiovascular diseases. A combined increase in both risk factors has been reported in a significant proportion of patients with coronary artery disease. Statins are the most widely used drugs to treat hypercholesterolemia, and they interact with blood pressure control in different populations of hypertensive patients. A significant reduction in blood pressure associated with the use of statins has been described in patients with untreated hypertension and in patients treated with antihypertensive drugs, particularly angiotensin converting enzyme inhibitors and calcium channel blockers. The effect of statins on blood pressure control has also been reported in diabetic patients. The mechanisms responsible for the hypotensive effect seem to be largely independent of the effect of statins on lipid profile, and are probably related to their interaction with endothelial function or angiotensin II receptors. The capacity of statins to improve blood pressure control could be a useful consideration for an integrated approach to better prevention of cardiovascular diseases.

Unsatisfactory blood pressure (BP) control in the treated hypertensive patient is largely related to poor compliance with antihypertensive drug regimens. The aim of the present study was to prospectively evaluate the rate of persistence on treatment and the extent of BP control in 301 elderly, uncomplicated grade I or II hypertensive patients randomly allocated to monotherapy with angiotensin-converting enzyme (ACE) inhibitors, calcium channel blockers (CCBs), beta-blockers, angiotensin II receptors (ARBs), or diuretics according to an open-label single-blind study design. After 24 months, the percentage of patients continuing their initial therapy was higher in those treated with ARBs (68.5%) and ACE inhibitors (64.5%) and lower in patients taking diuretics (34.4%; P<.01). The logistic regression model using ARBs as reference term showed that patients treated with ACE inhibitors (odds ratio [OR], 0.94; 95% confidence interval [CI], 0.79-0.99) or CCBs (OR, 0.76; 95% CI, 0.54-0.85) were more likely to continue their initial antihypertensive therapy when compared with those treated with beta-blockers (OR, 0.67; 95% CI, 0.57-0.79) or diuretics (OR, 0.56; 95% CI, 0.38-0.84). The average systolic and diastolic BP decrease was greater in patients treated with ARBs (-11.2+/-4/-5.8+/-2 mm Hg), ACE inhibitors (-10.5+/-4/-5.1+/-2 mm Hg), and CCBs (-8.5+/-3/-4.6+/-2 mm Hg) and lesser in those treated with diuretics (-2.3+/-4/-2.1+/-3 mm Hg, P<.05) and beta-blockers (-4.0+/-2/-2.3+/-2 mm Hg; P<.05). The study confirms the importance of persistence with treatment for the effective management of hypertension in clinical practice.
