Comparison of rosuvastatin with atorvastatin, simvastatin and pravastatin in achieving cholesterol goals and improving plasma lipids in hypercholesterolaemic patients with or without the metabolic syndrome in the MERCURY I trial

AIM: The metabolic syndrome (MS) increases the risk of coronary heart disease, yet few data are available on the effects of statin treatment in improving lipid measures in patients with the syndrome. This analysis compares the effects of statin therapy on plasma low-density lipoprotein cholesterol (LDL-C) goal achievement and lipid levels in hypercholesterolaemic patients with or without the MS. METHODS: The Measuring Effective Reductions in Cholesterol Using Rosuvastatin TherapY I (MERCURY I) trial compared rosuvastatin 10 mg with atorvastatin 10 mg and 20 mg, simvastatin 20 mg and pravastatin 40 mg over 8 weeks in patients with coronary or other atherosclerotic diseases or diabetes who had fasting levels of LDL-C of >or=2.99 mmol/l and triglycerides of <4.52 mmol/l. Modified National Cholesterol Education Program Adult Treatment Panel III (ATP III) criteria for the MS were met by 1342 (43%) of 3140 patients. RESULTS: LDL-C goal achievement rates and reductions in LDL-C, total cholesterol and non-high-density lipoprotein cholesterol (HDL-C) were similar in patients with and without the MS within statin treatment groups; triglycerides were reduced more and HDL-C tended to be increased more in patients with the MS, as expected. Treatment with rosuvastatin 10 mg was more effective in allowing patients with and without the MS to reach European and ATP III LDL-C goals, compared to atorvastatin 10 mg, simvastatin 20 mg and pravastatin 40 mg (p < 0.0001 for all comparisons); consistently produced greater reductions in LDL-C, total cholesterol and non-HDL-C, compared to these treatments; and produced similar or greater reductions in triglycerides and increases in HDL-C, compared to the other treatments. CONCLUSIONS: Statin therapy is effective in allowing LDL-C goal achievement and improving the lipid profile in hypercholesterolaemic high-risk patients with the MS. Rosuvastatin 10 mg presents significant advantages in goal achievement and lipid lowering over other statins at commonly used doses in patients both with and without the MS.     

Comparative effectiveness analysis of amlodipine/renin-Angiotensin system blocker combinations

J Clin Hypertens (Greenwich). 2012; 14:601–610. © 2012 Wiley Periodicals, Inc. A comparative effectiveness analysis of antihypertensive therapy amlodipine (AML) and angiotensin receptor blocker (ARB) fixed‐ and loose‐dose combinations (FDCs and LDCs) in achieving blood pressure (BP) reduction and Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure (JNC 7) goal attainment was made using retrospective electronic medical record (EMR) data. Treatment goal rates ranged from 35.0% for LDC AML/losartan to 45.7% for FDC AML/olmesartan (OM). FDC AML/OM achieved significantly greater reductions in systolic BP than FDC AML/benazepril (BEN), FDC AML/valsartan (VAL), and LDC AML/ARBs, respectively, and significantly greater reductions in diastolic BP than FDC AML/VAL and LDC therapy, respectively. Compared with patients treated with AML/OM, patients prescribed AML/VAL and LDC AML/ARB were significantly less likely to attain JNC 7 BP goal. Among subpopulations, AML/OM yielded higher rates of goal attainment among both African Americans and obese/overweight patients relative to AML/VAL and combined LDCs. Switchers from monotherapy with AML, OM, or VAL to AML/OM were significantly more likely to attain JNC 7 goals than those switching to AML/VAL or AML/BEN.     

Atorvastatin lowers plasma low-density lipoprotein cholesterol and C-reactive protein in Japanese type 2 diabetic patients

We investigated the meaning and the worth of lowering low-density lipoprotein cholesterol (LDL-C) to less than 100 mg/dL in Japanese type 2 diabetic patients using atorvastatin. As a multicenter open-labeled study, 84 type 2 diabetic Japanese patients with hypercholesterolemia were enrolled between September 2003 and April 2004. Subjects received 16 weeks of treatment with atorvastatin. High-sensitive C-reactive protein (hs-CRP), plasminogen activator inhibitor 1, monocyte chemotactic protein 1, interleukin 6, urine albumin-creatinine ratio, hemoglobin A(1c), total cholesterol, and LDL-C were measured at baseline and after 8 and 16 weeks of treatment. According to the Adult Treatment Panel III of the National Cholesterol Education Program, we divided the subjects into responders (final LDL-C <100 mg/dL) and nonresponders (final LDL-C > or =100 mg/dL). After 16 weeks of atorvastatin treatment, as well as a reduction of total cholesterol and LDL-C, a significant reduction of hs-CRP was observed. Plasminogen activator inhibitor 1, monocyte chemotactic protein 1, and interleukin 6 were not changed. After stratification, hs-CRP declined only in responders. We concluded that atorvastatin not only improved hypercholesterolemia, but also reduced CRP even in Japanese diabetic patients. The results of this stratified study suggest that achievement of the Adult Treatment Panel III treatment goal of LDL-C might assure a reduction of inflammation, which is associated with cardiovascular events.     

Efficacy and Safety of Long-Term Treatment With the Combination of Amlodipine Besylate and Olmesartan Medoxomil in Patients With Hypertension

The authors report on the 44-week open-label extension of the 8-week, double-blind Combination of Olmesartan Medoxomil and Amlodipine Besylate in Controlling High Blood Pressure (COACH) trial in 1684 patients. Initial therapy was amlodipine (AML) plus olmesartan medoxomil (OM) 5+40 mg/d, up-titrated to AML+OM 10+40 mg/d plus hydrochlorothiazide (HCTZ) 12.5 mg then 25 mg if patients did not achieve blood pressure (BP) goal (<140/90 mm Hg or <130/80 mm Hg in patients with diabetes). Baseline mean BP decreased from 164/102 mm Hg to 131/82 mm Hg at end of study, with an overall 66.7% of patients, including those with diabetes, achieving BP goal. The BP goal achievement was 80% for AML+OM 5+40 mg/d, 70.6% for AML+OM 10+40 mg/d, 66.6% for AML+OM+HCTZ 10+40+12.5 mg/d, and 46.3% for AML+OM+HCTZ 10+40+25 mg/d. Study medication was safe and well tolerated. Combination antihypertensive therapy with AML+OM±HTCZ, up-titrated as necessary, allowed a majority of patients to achieve BP goal.     

Blood pressure and lipid goal attainment in the hypertensive population in the primary care setting in Spain

Although blood pressure (BP) control is crucial in hypertensive patients, clinical practice guidelines agree that the goal of treatment should be aimed at not only decreasing BP but reducing global cardiovascular risk. The aim of this cross-sectional study was to evaluate BP, low-density lipoprotein cholesterol (LDL-C), and composite control rates in a hypertensive population in a primary care setting in Spain. Good BP control was defined as <140/90 mm Hg (<130/80 mm Hg for diabetics).LDL-C control rate was established according to the third report of the National Cholesterol Education Program Adult Treatment Panel criteria. A total of 12,954 patients (49.9% women, aged 62.1+/-10.7 years) were included. BP was controlled in 24.8% of patients, LDL-C in 26% of patients and, when combined, in only 8.6%. The rates of control were significantly worse in high-risk subgroups, such as high-coronary-risk, diabetic, or metabolic syndrome patients. The BP and LDL-C control rates in the hypertensive population attended to daily in primary care settings in Spain are low.     

Single-pill amlodipine/atorvastatin helps patients of diverse ethnicity attain recommended goals for blood pressure and lipids (the Gemini-AALA study)

The Gemini-AALA (Australia, Asia, Latin America, Africa/Middle East) study evaluated the efficacy and safety of single-pill amlodipine/atorvastatin (Caduet) for the treatment of patients of diverse ethnicity with concomitant hypertension and dyslipidaemia. This was a 14-week, open-label study including patients from 27 countries across the Middle East, Asia-Pacific, Africa and Latin America. Eight dosage strengths of single-pill amlodipine/atorvastatin (5/10, 10/10, 5/20, 10/20, 5/40, 10/40, 5/80 and 10/80 mg) were titrated to improve blood pressure and lipid control. Blood pressure and lipid goals were determined according to the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC 7) and National Cholesterol Education Program Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults (NCEP ATP III) guidelines, respectively (blood pressure, <140/90 or <130/80 mm Hg; low-density lipoprotein cholesterol (LDL-C), <4.1 to <2.6 mmol l(-1) (<160 to <100 mgdl(-1))). Overall, 1649 patients received study medication. Most patients (91.4%) had >or=1 cardiovascular risk factor (as defined by NCEP ATP III guidelines) in addition to hypertension/dyslipidaemia, and 61.7% had coronary heart disease/risk equivalent. At baseline, mean blood pressure was 146.6/88.3 mm Hg and LDL-C was 3.4 mmol l(-1) (130.2 mgdl(-1)). At week 14, 55.2% of patients reached both blood pressure and lipid goals, 61.3% reached blood pressure goal and 87.1% reached lipid goal (34.0% were at lipid goal at baseline). Mean blood pressure reduction was 20.2/11.4 mm Hg. For patients who were lipid-lowering drug naive at baseline, mean reduction in LDL-C was 41.0%. Treatment-related adverse events led to the discontinuation of 3.6% of patients. Single-pill amlodipine/atorvastatin therapy was well tolerated and effective for the reduction of blood pressure and lipids to recommended goals in patients from diverse ethnic backgrounds.     

Treatment of Hypertension Among African Americans: The Jackson Heart Study

Hypertension treatment regimens used by African American adults in the Jackson Heart Study were evaluated at the first two clinical examinations (2415 treated hypertensive persons at examination I [exam I], 2000–2004; 2577 at examination II [exam II], 2005–2008). Blood pressure (BP) was below 140/90 mm Hg for 66% and 70% of treated participants at exam I and exam II, respectively. The Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure treatment targets were met for 56% and 61% at exam I and exam II, respectively. Persons with diabetes or chronic kidney disease were less likely to have BP at target, as were men compared with women. Thiazide diuretics were the most commonly used antihypertensive medication, and persons taking a thiazide were more likely to have their BP controlled than persons not taking them; thiazides were used significantly less among men than women. Although calcium channel blockers are often considered to be effective monotherapy for African Americans, persons using calcium channel blocker monotherapy were significantly less likely to be at target BP than persons using thiazide monotherapy.     

Antihypertensive efficacy of Irbesartan/HCTZ in men and women with the metabolic syndrome and type 2 diabetes

This subgroup analysis of the Irbesartan/Hydrochlorothiazide (HCTZ) Blood Pressure Reductions in Diverse Patient Populations (INCLUSIVE) trial evaluated the efficacy and safety of irbesartan/HCTZ fixed combinations in adults with uncontrolled systolic blood pressure (SBP) (140-159 mm Hg; 130-159 mm Hg for type 2 diabetes mellitus [T2DM]) after >or=4 weeks of antihypertensive monotherapy. Treatment was sequential: placebo (4-5 weeks), HCTZ 12.5 mg (2 weeks), irbesartan/HCTZ 150/12.5 mg (8 weeks), and irbesartan/HCTZ 300/25 mg (8 weeks). In the intent-to-treat analysis, mean change from baseline (end of placebo phase) off all previous therapy to Week 18 (study end) in T2DM patients (n=227) was -18.2+/-14.1 mm Hg for SBP (primary end point; p<0.001) and -8.7+/-8.2 mm Hg for diastolic blood pressure (p<0.001). Mean SBP/diastolic blood pressure changes in patients with the metabolic syndrome (n=345) were -21.0+/-14.3/-10.4+/-8.5 mm Hg (p<0.001). Overall, 56% (95% confidence interval, 49%-62%) of T2DM and 73% (95% confidence interval, 68%-77%) of metabolic syndrome patients achieved SBP goal (<140 mm Hg; <130 mm Hg for T2DM). Goal attainment rates were significantly higher among women with the metabolic syndrome than men. Treatments appeared to be well tolerated. Irbesartan/HCTZ fixed combinations achieved SBP goals in over half of the T2DM patients and nearly three quarters of patients with the metabolic syndrome, with SBP uncontrolled on antihypertensive monotherapy.     

Treatment of heterozygous familial hypercholesterolemia: atorvastatin vs simvastatin

BACKGROUND AND AIM: This study compares the cholesterol-lowering efficacy of atorvastatin and simvastatin in attainment of the National Cholesterol Education Program (NCEP) guidelines LDL-cholesterol (LDL-C) goal in patients with heterozygous familial hypercholesterolemia (HFH). The association of atorvastatin with significant changes of blood fibrinogen and other coagulative variables was also compared with that of simvastatin. METHODS AND RESULTS: In a 24-week study, 26 HFH patients (16 men, 10 women, mean age 55.1 +/- 11.3) were randomly assigned to receive atorvastatin or simvastatin. The initial daily dose of 10 mg was progressively raised to 20, 40 and 80 mg in patients who had not reached the NCEP LDL-C goal. Significant reductions of total and LDL-C (p < 0.001), triglycerides (p < 0.005) and apoB100 (p < 0.001) were observed in both groups. Atorvastatin caused greater reductions in total cholesterol (-42% vs -30%) (p < 0.001) and LDL-C (-50% vs -37%) (p < 0.01). Three patients treated with Atorvastatin (23%) and none of those treated with simvastatin reached the NCEP LDL-C goal at the end of the study. No significant departures from the fibrinogen and coagulative variable baselines were observed. CONCLUSIONS: Atorvastatin has greater cholesterol-lowering efficacy than simvastatin in HFH.     

A comparative study with rosuvastatin in subjects with metabolic syndrome: results of the COMETS study.

AIMS: The efficacy and safety of rosuvastatin, atorvastatin, and placebo were compared in patients with the metabolic syndrome. METHODS AND RESULTS: Patients with the metabolic syndrome with low-density lipoprotein cholesterol (LDL-C) > or =3.36 mmol/L (130 mg/dL) and multiple risk factors conferring a 10-year coronary heart disease risk score of >10% were randomized (2:2:1) to receive rosuvastatin 10 mg, atorvastatin 10 mg, or placebo for 6 weeks. Subsequently, the rosuvastatin 10 mg and placebo groups received rosuvastatin 20 mg and the atorvastatin 10 mg group received atorvastatin 20 mg for 6 weeks. LDL-C was reduced significantly more in patients receiving rosuvastatin 10 mg when compared with those receiving atorvastatin 10 mg at 6 weeks [intention-to-treat (ITT) population by randomized treatment: 41.7 vs. 35.7%, P < 0.001; ITT population by as-allocated treatment: 42.7 vs. 36.6%, P < 0.001]. Significant LDL-C reductions were also observed in patients receiving rosuvastatin when compared with those receiving atorvastatin at 12 weeks (48.9 vs. 42.5%, P < 0.001). More patients achieved LDL-C goals with rosuvastatin when compared with atorvastatin. Rosuvastatin increased high-density lipoprotein cholesterol significantly more than atorvastatin. Treatments were well tolerated. CONCLUSION: At equivalent doses, rosuvastatin had a significantly greater effect than atorvastatin in lowering LDL-C and improving the lipid profile and was well tolerated in patients with the metabolic syndrome.     

Rosuvastatin is cost-effective compared with atorvastatin in reaching cholesterol goals

BACKGROUND: Lowering low-density lipoprotein cholesterol (LDL-C) levels reduces the risk of coronary heart disease. The introduction of a highly efficacious new statin, rosuvastatin, may enable more patients to be treated to LDL-C goal within a fixed budget. OBJECTIVES: To compare the cost-effectiveness of rosuvastatin 10 mg and atorvastatin 10 mg in lowering LDL-C and achieving guideline goals after 12 weeks of treatment. The LDL-C goals were those recommended by the National Cholesterol Education Program Adult Treatment Panel (NCEP ATP) III and the Third Joint European Task Force. METHODS: The analysis was performed on pooled data from three clinical trials. Efficacy was measured as the percent reduction in LDL-C and the proportion of patients who reached guideline LDL-C goals following the first 12 weeks of treatment, prior to dose titration. Costs comprised drug acquisition costs only. The cost-effectiveness measures were cost per 1% reduction in LDL-C and cost per patient treated to their LDL-C goal. RESULTS: Treatment with rosuvastatin 10 mg costs 1.85 per 1% reduction in LDL-C, compared with 2.37 per 1% reduction with atorvastatin 10 mg. The average costs per patient treated to the European LDL-C goals were 130.18 for rosuvastatin 10 mg and 242.44 for atorvastatin 10 mg. Treating to NCEP ATP III goals costs 115 per patient treated with rosuvastatin 10 mg vs. 163 per patient treated with atorvastatin 10 mg. CONCLUSIONS: Rosuvastatin has the same acquisition costs as and is more efficacious than atorvastatin in lowering LDL-C and treating patients to target LDL-C levels.     

Plasma endothelin in postmenopausal women with type 2 diabetes mellitus and metabolic syndrome: a comparison of oral combined and transdermal oestrogen-only replacement therapy

SUMMARY
Aim   Type 2 diabetes and metabolic syndrome are major cardiovascular risk factors in postmenopausal women, but the role of vasoconstrictive endothelin-1 (ET-1) in these conditions is not known. We studied the levels of ET-1 and the effect of postmenopausal hormonal therapy on ET-1 levels in postmenopausal women.
Methods   We compared plasma levels of ET-1 in 22 postmenopausal type 2 diabetic women and 14 postmenopausal women with metabolic syndrome with plasma levels in 10 healthy postmenopausal control women. The basal values for ET-1 were measured for all groups. These women were then randomised to receive in a double-dummy, crossover trial: either oral continuous oestradiol (2.0 mg) + norethisterone acetate (1.0 mg) per day or continuous transdermal oestrogen-only (50 μg/day) for 3 months. Between the active therapy there were 3-month wash-out periods. ET-1-values were measured again at the end of each treatment period.
Results   The type 2 diabetic women had significantly (p < 0.003) elevated ET-1 levels (4.8 ± 1.0 pg/ml) whereas those with metabolic syndrome (4.4 ± 1.7 pg/ml) had non-significantly (NS) elevated ET-1 levels compared to controls (3.6 ± 0.3 pg/ml). Both oral and transdermal hormone replacement therapy (HRT) failed to affect plasma ET-1 except in 14 hypertensive women from the diabetes and metabolic syndrome groups who were on angiotensin convertase enzyme (ACE) inhibitors. These women's ET-1 levels before oral HRT (4.6 ± 1.1 pg/ml) fell to 4.1 ± 0.9 pg/ml (p < 0.05).
Conclusions   Type 2 diabetes in postmenopausal women is associated with elevated ET-1 levels. Oestrogen replacement therapy does not affect the levels of ET-1 in postmenopausal women with type 2 diabetes or metabolic syndrome.     

Effects of switching statins on achievement of lipid goals: measuring effective reductions in cholesterol using rosuvastatin therapy (MERCURY I) study

Background

In a multinational trial (4522IL/0081), we assessed the effects of switching to low doses of rosuvastatin from commonly used doses of atorvastatin, simvastatin, and pravastatin on low-density lipoprotein cholesterol (LDL-C) goal achievement in high-risk patients.

Methods

Hypercholesterolemic patients (n = 3140) with coronary heart disease, atherosclerosis, or type 2 diabetes were randomized to open-label rosuvastatin 10 mg, atorvastatin 10 or 20 mg, simvastatin 20 mg, or pravastatin 40 mg for 8 weeks. Patients either remained on these treatments for another 8 weeks or switched treatments from atorvastatin 10 mg, simvastatin 20 mg, and pravastatin 40 mg to rosuvastatin 10 mg or from atorvastatin 20 mg to rosuvastatin 10 or 20 mg. The primary efficacy measure was the proportion of patients reaching the Joint European Societies' LDL-C goal (<116 mg/dL) at week 16. For measures of cholesterol goal achievement, treatment arms were compared using logistic-regression analysis.

Results

Significant improvement in LDL-C goal achievement was found for patients who switched to rosuvastatin 10 mg, compared with patients who remained on atorvastatin 10 mg (86% vs 80%, P < .05), simvastatin 20 mg (86% vs 72%, P < .0001), and pravastatin 40 mg (88% vs 66%, P < .0001), and between patients switched to rosuvastatin 20 mg and those who remained on atorvastatin 20 mg (90% vs 84%, P < .01). Similar results were found for achievement of the European combined LDL-C and total cholesterol goals and National Cholesterol Education Program Adult Treatment Panel III LDL-C goals. All statins were well tolerated over 16 weeks.

Conclusions

We demonstrated that switching to a more efficacious statin is an effective strategy to improve lipid goal achievement in patients requiring lipid-lowering therapy.     

Guidelines for hypertension: are quality-assurance measures on target?

Guideline committees recommend targets of treatment based on trial data on efficacy and effectiveness. Quality-assurance initiatives apply these parameters in the general practice setting. Therefore, targets must be feasible and achievable by the practicing physicians who are judged by these targets as goals for care. We evaluated 437 patients in the Rush University Hypertension Clinic using the Health Employer Data Information Set (HEDIS) measures for 2000 to assess goal achievement in a practice-based setting. We compared guideline achievement of uncomplicated hypertensive and diabetic subjects to standards dictated by HEDIS, the 6th Joint National Committee on the Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC VI), and the American Diabetic Association (ADA)/National Kidney Foundation (NKF). Overall, 276 (63%) patients achieved SBP goal, with 376 (86%) achieving DBP goal and 358 (59%) achieving both goals. However, in the 20% of patients who were diabetic, only 52% had a BP of <140 mm Hg and <90 mm Hg, whereas only 22% achieved the more stringent goals of JNC VI of <130 mm Hg systolic and <85 mm Hg diastolic and only 15% achieved the ADA/NKF goals of <130 mm Hg systolic and <80 mm Hg diastolic. Although goal was achievable in most uncomplicated hypertension, hypertension in diabetes was more difficult to control, despite being more likely to receive enhanced benefit from effective management. Goal-oriented strategy, especially in diabetic subjects, should be aggressively sought rather than relaxing goals to promote achievement.     

Blood pressure control and physician management of hypertension in hospital hypertension units in Spain

Goal blood pressure (BP) was defined by the Sixth Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC-VI) and the World Health Organization-International Society of Hypertension (WHO/ISH) as <140 mm Hg systolic and <90 mm Hg diastolic for the general and <130 mm Hg systolic and <85 mm Hg diastolic for special high-risk populations. However, there are few reports that address BP control among special subgroups of hypertensives by reference to targeted BP. We therefore conducted a study to evaluate BP control of 4049 hypertensives in 47 hospital-based hypertension units in Spain. Overall, 42% of patients achieved goal BP (<140 mm Hg systolic and <90 mm Hg diastolic). Only 13% of diabetic patients and 17% of those with renal disease achieved the BP goal (<130 mm Hg systolic and <85 mm Hg diastolic), and only 10% and 12%, respectively, achieved the even more rigorous goal (<130 mm Hg systolic and <80 mm Hg diastolic). Likewise, only 18% of patients in JNC-VI risk group C and 17% of WHO/ISH high-risk patients attained a goal BP <130 mm Hg systolic and <85 mm Hg diastolic. BP control (<125 mm Hg systolic and <75 mm Hg diastolic) was extremely low (2%) in patients with proteinuria >1 g/d. Poorer BP control was observed among patients at high risk, with diabetes, renal disease, or obesity, than in lower-risk groups. BP control was lower for systolic than for diastolic BP. In >50% of uncontrolled patients, no measures were taken by doctors to optimize pharmacologic treatment, and approximately one-third of patients were still using drug monotherapy. Control of BP, particularly of systolic BP, is still far from optimal in hospital-based hypertension units. Patients at high risk, with diabetes or proteinuria, warrant focused attention. Moreover, a more aggressive behavior of doctors treating uncontrolled hypertension is needed.     

Blood Pressure Control in Hypertensive Patients in Irish Primary Care Practices

In Ireland, cardiovascular disease is a major cause of death. However, blood pressure (BP) goal achievement is unsatisfactory. The authors aimed to document BP control and increase awareness. A total of 1534 patients were enrolled in the study, with a mean age of 64.7±11.9 years (53.8% women). Duration of hypertension was 8.7±7.7 years, and 14.6% had diabetes, 13.8% had coronary artery disease, and 40.5% were taking antihypertensive monotherapy. β-Blockers (39.8%), angiotensin-converting enzyme inhibitors (32.2%), and angiotensin receptor blockers (22.0%) were prescribed most frequently. Mean BP was 136.0±6.1 mm Hg/89.5±5.0 mm Hg in nondiabetic patients (48.6% <140/90 mm Hg) and 131.0±7.4 mm Hg/81.7±4.6 mm Hg in diabetic patients (16.7% <130/80 mm Hg). Diet, exercise, and lifestyle modifications (63.5%) were frequently recommended. Increased patient awareness and compliance together with the adherence of physicians to current guidelines and greater willingness to take action in patients with uncontrolled hypertension should help in improving BP control and thus reduce cardiovascular risk.     

Ultrasonographic comparison of gastric motility between diabetic gastroparesis patients with and without metabolic syndrome

Background and Aims:  Diabetic patients with poor glycemic control or long standing disease often have impaired gastric motility. Recently, metabolic factors such as blood glucose have been reported as influencing gastric motility independently of autonomic neuropathy. Many diabetic patients have metabolic syndrome, which is strongly associated with coronary and other diseases. We investigated whether metabolic syndrome influences diabetic gastroparesis patients.
Methods:  We observed gastric motility ultrasonographically in diabetic gastroparesis patients including nine with and nine without metabolic syndrome. Both groups complained of upper abdominal symptoms when hospitalized to improve blood sugar control. All patients underwent upper gastrointestinal endoscopy to rule out gastric and duodenal lesions. All had autonomic neuropathy. Gastric motility was evaluated within 3 days after admission by transabdominal ultrasonography after a test meal.
Results:  Gastric emptying was 45.0 ± 13.7% in patients with and 39.1 ± 11.9% in patients without metabolic syndrome, which was not statistically significant. Frequency of gastric contractions was 8.33 ± 2.78 per 3 min in patients with metabolic syndrome and 7.44 ± 2.13 per 3 min in the others, which was not statistically significant. The motility index, which involves antral contractility, was 3.21 ± 2.18 in patients with metabolic syndrome and 2.80 ± 1.87 in the others, which was not statistically significant.
Conclusions:  Metabolic syndrome did not appear to contribute to delayed gastric motility in diabetic gastroparesis.     

Comparative antihypertensive efficacy of angiotensin receptor blocker-based treatment in African-American and white patients

Blood pressure (BP) reductions with agents that block the renin-angiotensin system are regarded as less effective as monotherapy in African Americans than other ethnic groups. This practice-based study compares the efficacy of an angiotensin receptor blocker-based regimen in African-American and Caucasian patients. Included in the 10-week study were 173 African-American and 1296 Caucasian patients. Efficacy was based on differences in 24-hour ambulatory BP. After baseline ambulatory BP monitoring and office BPs were obtained, all patients were started or switched to the angiotensin receptor blocker telmisartan, 40-80 mg daily, plus hydrochlorothiazide 12.5 mg daily (if needed for office BP control: <140/90 mm Hg). More African Americans required the addition of a low-dose thiazide diuretic than Caucasians (47.3% vs. 34.9%; p=0.021). Once patients with white coat hypertension were excluded (i.e., those with baseline ambulatory BP monitoring <130/80 mm Hg), ambulatory BP monitoring changes were similar between groups. A greater proportion of African Americans than Caucasians without white coat hypertension also needed combination therapy (52.1% vs. 39.5%; p=0.04). While achievement of BP goal was similar between groups by office criterion (<140/90 mm Hg), differences were noted by ambulatory BP monitoring (<130/80 mm Hg) (48.0% in African American vs. 63.2% in Caucasians; p=0.01) despite the same BP reductions, reflecting higher baseline values in African Americans. We conclude that an angiotensin receptor blocker as part of a BP-lowering strategy is effective in previously untreated African-American patients, although a higher proportion will require the use of a diuretic compared with Caucasians.     

Efficacy and safety of atorvastatin in hyperlipidemic, type 2 diabetic patients. A 34-week, multicenter, open-label study

Hyperlipidemia is common in type 2 diabetic patients and is an independent risk factor for cardiovascular disease. The aim of this trial was to evaluate the efficacy and safety of once-daily atorvastatin 10-80 mg for the treatment of hyperlipidemia in type 2 diabetics with plasma low-density lipoprotein cholesterol (LDL-C) levels exceeding 3.4 mmol/l (130 mg/dl). One hundred and two patients met the study criteria and received 10 mg/day atorvastatin. Patients who reached the target LDL-C level of 相似文献
