Combined Treatment with Amlodipine and Atorvastatin Calcium Reduces Circulating Levels of Intercellular Adhesion Molecule-1 and Tumor Necrosis Factor-α in Hypertensive Patients with Prediabetes. Front Aging Neurosci 2016; 8:206. [PMID: 27610083 PMCID: PMC4996984 DOI: 10.3389/fnagi.2016.00206] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2016] [Accepted: 08/11/2016] [Indexed: 01/23/2023] Open
Abstract
Objective: To assess the effect of amlodipine and atorvastatin on intercellular adhesion molecule (ICAM)-1 and tumor necrosis factor (TNF)-α expression, as endothelial function and inflammation indicators, respectively, in hypertensive patients with and without prediabetes. Methods: Forty-five consecutive patients with hypertension, diagnosed according to JNC7, were divided into two groups based on the presence (HD group, n = 23) or absence (H group, n = 22) of prediabetes, diagnosed according to 2010 ADA criteria, including impaired glucose tolerance (IGT) and fasting glucose tests. All patients simultaneously underwent 12-week treatment with daily single-pill amlodipine besylate/atorvastatin calcium combination (5/10 mg; Hisun-Pfizer Pharmaceuticals Co. Ltd). Serum isolated before and after treatment from overnight fasting blood samples was analyzed by ELISA. Results: In the HD and H groups after vs. before 12-week amlodipine/atorvastatin treatment, there were significantly (all P < 0.01) lower levels of ICAM-1 (3.06 ± 0.34 vs. 4.07 ± 0.70 pg/ml; 3.26 ± 0.32 vs. 3.81 ± 0.60 pg/ml, respectively) and TNF-α (78.71 ± 9.19 vs. 110.94 ± 10.71 pg/ml; 80.95 ± 9.33 vs. 101.79 ± 11.72 pg/ml, respectively), with more pronounced reductions in HD vs. H group (ICAM-1Δ: 1.01 ± 0.80 vs. 0.55 ± 0.64 pg/ml, respectively, P = 0.037; TNF-αΔ: 32.23 ± 14.33 vs. 20.84 ± 14.89 pg/ml, respectively, P = 0.011), independent of the blood pressure (BP) and cholesterol level reduction. Conclusions: Amlodipine/atorvastatin improved endothelial function and inflammation, as reflected by lower circulating levels of ICAM-1 and TNF-α, more prominently in hypertensives with than without prediabetes. Starting statin treatment before overt diabetes in hypertensives might thus improve cardiovascular outcomes.

Evaluation of statin therapy on endothelial function in hypercholesterolemic rabbits by automatic measurement of arterial wall movement using ultrasound images. ULTRASOUND IN MEDICINE & BIOLOGY 2014; 40:2415-2424. [PMID: 25018028 DOI: 10.1016/j.ultrasmedbio.2014.03.032] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/06/2013] [Revised: 01/13/2014] [Accepted: 03/31/2014] [Indexed: 06/03/2023]
Abstract
The aim of this study was to evaluate arterial endothelial function, assessed as acetylcholine-mediated dilation (AMD), in a hypercholesterolemic atherosclerotic rabbit model to investigate the effects of atorvastatin in the atherosclerotic process, using a new computerized analysis model and ultrasound images. Twenty-seven rabbits were fed a high-cholesterol (2%) diet for 6 wk and then divided into three groups for an additional 9 wk: Group A received regular chow food, group B received a 2% cholesterol-rich diet plus atorvastatin drug, and group C received regular chow food plus atorvastatin. Ultrasound examinations of endothelial function of the rabbit abdominal aorta artery were performed immediately after the 6 weeks (0 wk) and then 3, 6 and 9 wk after that. For off-line analysis, a computerized analysis method for evaluating instantaneous changes in the wall of the rabbit abdominal aorta was used. As parameters of improvement resulting from treatment, endothelium-dependent acetylcholine-induced dilation and endothelium-independent nitroglycerin-induced dilation were evaluated in treated rabbits. Differences among groups were tested using analysis of variance. On histopathology, intima-media thickness decreased after treatment in all groups. There were no significant differences in arterial diameter and blood velocity changes among treated rabbits at 0, 3, 6 and 9 wk of treatment in all groups, except in end-diastolic velocity, radial strain percentage, pulse index and resistance index in group C. In group A, AMD did not significantly improve after 3, 6 and 9 wk, as compared with 0 wk. Atorvastatin treatment significantly increased AMD (18%) at 3 wk in group B, compared with week 0. AMD significantly increased after 3 (26%), 6 (124%) and 9 (182%) wk in group C, compared with 0 wk. It is concluded that the new automatic method enables accurate and repeated evaluation of endothelial function during the progression and regression of atherosclerosis. Also, the results obtained in this study indicate that short-term administration of atorvastatin can improve endothelial function in cholesterol-fed rabbits.

Comparison of outcomes in patients with ST-segment elevation myocardial infarction discharged on versus not on statin therapy (from the Harmonizing Outcomes With Revascularization and Stents in Acute Myocardial Infarction Trial). Am J Cardiol 2014; 113:1273-9. [PMID: 24576541 DOI: 10.1016/j.amjcard.2014.01.401] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/22/2013] [Revised: 01/08/2014] [Accepted: 01/08/2014] [Indexed: 11/23/2022]
Abstract
Statin therapy is indicated after ST-segment elevation myocardial infarction (STEMI) to reduce recurrent ischemic events, but approximately 6% of patients with STEMI do not receive a statin prescription at discharge. This substudy aimed to define the clinical outcomes and patient characteristics associated with statin nonprescription after STEMI. We compared clinical, angiographic, and procedural characteristics and in-hospital, 30-day, 1-year, 2-year, and 3-year outcomes in 3,512 patients discharged after STEMI with and without (6%) statin prescriptions in the harmonizing outcomes with revascularization and stents in acute myocardial infarction trial (www.clinicaltrials.gov, NCT00433966). Statin nonprescription was associated with female sex, nonwhite race, previous bypass surgery, heart failure, renal impairment, anemia, thrombocytopenia, care in the United States, lower prescription rates of antiplatelets and neurohormonal antagonists, less percutaneous coronary intervention and stents, and, in 26% of cases, angiographically normal or nonobstructed coronary arteries. At every time point of follow-up after discharge, patients with no discharge statin prescription had significantly higher rates of net adverse clinical events, major adverse cardiac events, major bleeding unrelated to bypass surgery, and death. After multivariable adjustment, absence of a discharge statin prescription independently predicted 3-year major adverse cardiac event (hazard ratio 1.54, 95% confidence interval 1.15 to 2.07, p=0.0037) and death (hazard ratio 2.30, 95% confidence interval 1.41 to 3.77, p=0.0009). In conclusion, within the framework of this randomized trial of patients presenting with STEMI, approximately 6% of patients were discharged without statin therapy. Absence of a discharge statin prescription after STEMI was an independent predictor of ischemic events including death.

Abstract
OBJECTIVE We sought to use cardiac CT angiography (CTA) to longitudinally examine the relationship between changes in aortic stiffness and of the atherosclerotic burden over time. MATERIALS AND METHODS One hundred sixty-four patients with suspected coronary artery disease underwent two retrospectively ECG-gated cardiac CTA studies an average of 12 ± 10 months apart. Arterial stiffness was represented by the aortic distensibility index (ADI) and atherosclerosis by segment involvement score (SIS) (defined as the number of coronary artery segments per patient displaying atherosclerotic plaque). Changes in ADI and SIS between the studies were compared using linear and logistic regression accounting for differences in clinical and demographic baseline characteristics. RESULTS Age (p = 0.004), time between studies (p = 0.02), and increase in SIS (p < 0.001) were associated with a decrease in ADI on univariate analysis. Increase in SIS remained a significant independent predictor of decreased ADI on both multivariate logistic regression (with change in ADI represented categorically) and multivariate linear regression (both p < 0.001). CONCLUSION On longitudinal evaluation with cardiac CTA, the progression of aortic stiffness is associated with the progression of coronary atherosclerosis. Although outcome studies are needed, a comprehensive assessment of vascular health with cardiac CTA, including both indexes of arterial stiffness and atherosclerotic burden, may improve risk stratification and therapy monitoring.

Abstract
The endothelium is a major regulator of cardiovascular function and maintains an atheroprotective role through several mechanisms, including vasodilatation, inhibition of platelet aggregation, having anticoagulant and profibrinolytic effects, and having an anti-inflammatory effect. Early changes in the normal functioning of the endothelium are key initiating factors in the development and progression of atherosclerosis. These changes are present well before the presentation of clinical symptoms. Thus, researchers have focused much attention on developing methods for reliable non-invasive testing of endothelial function to allow early detection and monitoring and progression of subclinical atherosclerosis. To date, there is a wide range of methods in use to assess endothelial function, each with its own advantages and limitations. Ideally, the tests should be non-invasive to allow repeated measurements and be applicable in normal healthy subjects and also in children. Given the wide range of regulatory functions of the endothelium, it is not surprising that there is no single measure of endothelial function that provides all the necessary information regarding vascular integrity in different vascular beds. Therefore, a combination of tests examining different components of the vascular system is more appropriate. Since patients with rheumatoid arthritis have increased mortality due to cardiovascular disease, assessment of endothelial function could prove to be useful tools in the identification and monitoring of cardiovascular risk. The purpose of this review is to give a brief overview of some of the commonly used techniques for assessment of endothelial function, and in particular on those that have been used in studies of patients with rheumatoid arthritis.

Abstract
Impaired aortic distensibility index (ADI) is associated with cardiovascular risk factors. This study evaluates the relation of ADI measured by computed tomographic angiography (CTA) with the severity of coronary atherosclerosis in subjects with suspected coronary artery disease (CAD). Two hundred and twenty-nine subjects,age 63 ± 9 years, 42% female, underwent coronary artery calcium (CAC) scanning and CTA, and their ADI and Framingham risk score (FRS) were measured. End-systolic and end-diastolic (ED) cross-sectional-area(CSA) of ascending-aorta (AAo) was measured 15-mm above the left-main coronary ostium. ADI was defined as: [(Δlumen-CSA)/(lumen-CSA in ED × systemic-pulse-pressure) × 103]. ADI measured by 2D-trans-thoracic echocardiography (TTE) was compared with CTA-measured ADI in 26 subjects without CAC. CAC was defined as 0, 1–100, 101–400 and 400+. CAD was defined as luminal stenosis 0, 1–49% and 50%+. There was an excellent correlation between CTA- and TTE-measured ADI (r2 = 0.94, P = 0.0001). ADI decreased from CAC 0 to CAC 400+; similarly from FRS 1–9% to FRS 20% + (P < 0.05). After adjustment for risk factors, the relative risk for each standard deviation decrease in ADI was 1.66 for CAC 1–100, 2.26 for CAC 101–400 and 2.32 for CAC 400+ as compared to CAC 0; similarly, 2.36 for non-obstructive CAD and 2.67 for obstructive CAD as compared to normal coronaries. The area under the ROC-curve to predict significant CAD was 0.68 for FRS, 0.75 for ADI, 0.81 for CAC and 0.86 for the combination (P < 0.05). Impaired aortic distensibility strongly correlates with the severity of coronary atherosclerosis. Addition of ADI to CAC and traditional risk factors provides incremental value to predict at-risk individuals.

Abstract
Amlodipine/atorvastatin (Caduet) is a single-tablet, fixed-dose combination of the dihydropyridine calcium channel antagonist amlodipine and the HMG-CoA reductase inhibitor atorvastatin. The bioavailability of amlodipine and atorvastatin with a single-tablet, fixed-dose amlodipine/atorvastatin combination was not significantly different to that with coadministered separate amlodipine and atorvastatin tablets. In well controlled clinical trials in patients with hypertension and dyslipidaemia, once-daily amlodipine and atorvastatin (administered as the single-tablet, fixed-dose combination or coadministered as two separate tablets) effectively reduced systolic BP (SBP) and low-density lipoprotein cholesterol (LDL-C) levels, and enabled more patients to achieve BP and LDL-C goals than single-agent or placebo therapy. There was no modification of the effect of amlodipine on SBP when administered in combination with atorvastatin and there was no modification of the effect of atorvastatin on LDL-C when administered in combination with amlodipine. In noncomparative, titration-to-goal, open-label 'real-world' trials, the single-tablet, fixed-dose combination of amlodipine/atorvastatin enabled patients with hypertension and dyslipidaemia to achieve both BP and LDL-C goals. Administration of a single tablet of amlodipine/atorvastatin, compared with coadministration of these agents as two separate tablets, improved patient adherence, according to a retrospective study that utilized prescription refill rates from a large US insurance database. Data from the large, randomized, double-blind, placebo-controlled ASCOT-LLA trial also demonstrated that the combination of amlodipine-based therapy and atorvastatin was effective in preventing cardiovascular (CV) endpoints in hypertensive patients at risk of CV disease (CVD). In summary, amlodipine/atorvastatin offers a convenient and effective approach to improving adherence and managing CV risk in hypertensive patients with dyslipidaemia or at risk of CVD.

Abstract
Patients with rheumatoid arthritis (RA) have a reduced life expectancy when compared with the general population, largely attributable to cardiovascular disease. Factors that contribute to this increased cardiovascular risk include traditional risk factors, which account for only part of the excess, along with manifestations of the disease itself. RA is characterized by inflammation, which also is a key component in the development of atherosclerosis. Inflammation leads to the activation of endothelial cells, which, through an increase in the expression of leukocyte adhesion molecules, promotes a pro-atherosclerotic environment. Endothelial dysfunction is an early preclinical marker of atherosclerosis, and is commonly found in patients with RA. Several methods are available for the assessment of endothelial function, such as flow-mediated dilatation and laser Doppler flowmetry combined with iontophoresis, each with its own advantages and limitations. Studies have shown that endothelial dysfunction in RA is closely associated with inflammation, and therapeutic reduction of inflammation leads to improvements in endothelial function. As such, assessments of endothelial function could prove to be useful tools in the identification and monitoring of cardiovascular risk in patients with RA. Given the increase in cardiovascular mortality associated with RA, effective management must involve prevention of cardiovascular risk, in addition to control of disease activity and inflammation.

Abstract
PURPOSE OF REVIEW The present article reviews the use of flow-mediated dilatation in clinical cardiovascular research. Its value as a surrogate tool for development of antiatherosclerotic drugs and noninvasive assessment of cardiovascular risk is also discussed. RECENT FINDINGS Atherosclerosis remains the leading cause of cardiovascular morbidity and mortality. Development of new drugs is required to target both the evolution of this disease and its clinical consequences. Noninvasive measures of arterial function and structure have been widely used as intermediate phenotypes in clinical trials. Numerous studies have demonstrated the interplay between vascular risk factors and endothelial function as assessed by flow-mediated dilatation in children and adults. Additionally, a number of studies have documented the prognostic value of the method. SUMMARY Detection of early arterial changes can prove particularly useful in clinical research for the development of antiatherosclerotic drugs. They permit identification of vascular toxicity as well as characterization of the safety and risk profile of a new cardiovascular treatment modality on vascular health. This approach is likely to prove cost-effective before embarking on large longitudinal studies to assess cardiovascular morbidity and mortality.

Low fingertip temperature rebound measured by digital thermal monitoring strongly correlates with the presence and extent of coronary artery disease diagnosed by 64-slice multi-detector computed tomography. Int J Cardiovasc Imaging 2009; 25:725-38. [PMID: 19634001 PMCID: PMC2729419 DOI: 10.1007/s10554-009-9476-8] [Citation(s) in RCA: 33] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/16/2009] [Accepted: 07/07/2009] [Indexed: 12/04/2022]
Abstract
Previous studies showed strong correlations between low fingertip temperature rebound measured by digital thermal monitoring (DTM) during a 5 min arm-cuff induced reactive hyperemia and both the Framingham Risk Score (FRS), and coronary artery calcification (CAC) in asymptomatic populations. This study evaluates the correlation between DTM and coronary artery disease (CAD) measured by CT angiography (CTA) in symptomatic patients. It also investigates the correlation between CTA and a new index of neurovascular reactivity measured by DTM. 129 patients, age 63 ± 9 years, 68% male, underwent DTM, CAC and CTA. Adjusted DTM indices in the occluded arm were calculated: temperature rebound: aTR and area under the temperature curve aTMP-AUC. DTM neurovascular reactivity (NVR) index was measured based on increased fingertip temperature in the non-occluded arm. Obstructive CAD was defined as ≥50% luminal stenosis, and normal as no stenosis and CAC = 0. Baseline fingertip temperature was not different across the groups. However, all DTM indices of vascular and neurovascular reactivity significantly decreased from normal to non-obstructive to obstructive CAD [(aTR 1.77 ± 1.18 to 1.24 ± 1.14 to 0.94 ± 0.92) (P = 0.009), (aTMP-AUC: 355.6 ± 242.4 to 277.4 ± 182.4 to 184.4 ± 171.2) (P = 0.001), (NVR: 161.5 ± 147.4 to 77.6 ± 88.2 to 48.8 ± 63.8) (P = 0.015)]. After adjusting for risk factors, the odds ratio for obstructive CAD compared to normal in the lowest versus two upper tertiles of FRS, aTR, aTMP-AUC, and NVR were 2.41 (1.02–5.93), P = 0.05, 8.67 (2.6–9.4), P = 0.001, 11.62 (5.1–28.7), P = 0.001, and 3.58 (1.09–11.69), P = 0.01, respectively. DTM indices and FRS combined resulted in a ROC curve area of 0.88 for the prediction of obstructive CAD. In patients suspected of CAD, low fingertip temperature rebound measured by DTM significantly predicted CTA-diagnosed obstructive disease.
