Predicting 10-year risk of recurrent cardiovascular events andcardiovascular interventions in patients with established cardiovascular disease: results from UCC-SMART and REACH.

BACKGROUND: Existing cardiovascular risk scores for patients with established cardiovascular disease (CVD) estimate residual risk of recurrent major cardiovascular events (MACE). The aim of the current study is to develop and externally validate a prediction model to estimate the 10-year combined risk of recurrent MACE and cardiovascular interventions (MACE+) in patients with established CVD. METHODS: Data of patients with established CVD from the UCC-SMART cohort (N = 8421) were used for model development, and patient data from REACH Western Europe (N = 14,528) and REACH North America (N = 19,495) for model validation. Predictors were selected based on the existing SMART risk score. A Fine and Gray competing risk-adjusted 10-year risk model was developed for the combined outcome MACE+. The model was validated in all patients and in strata of coronary heart disease (CHD), cerebrovascular disease (CeVD), peripheral artery disease (PAD). RESULTS: External calibration for 2-year risk in REACH Western Europe and REACH North America was good, c-statistics were moderate: 0.60 and 0.58, respectively. In strata of CVD at baseline good external calibration was observed in patients with CHD and CeVD, however, poor calibration was seen in patients with PAD. C-statistics for patients with CHD were 0.60 and 0.57, for patients with CeVD 0.62 and 0.61, and for patients with PAD 0.53 and 0.54 in REACH Western Europe and REACH North America, respectively. CONCLUSIONS: The 10-year combined risk of recurrent MACE and cardiovascular interventions can be estimated in patients with established CHD or CeVD. However, cardiovascular interventions in patients with PAD could not be predicted reliably.

Clinical characteristics and outcomes of COMPASS eligible patients in France. An analysis from the REACH Registry.

BACKGROUND: Following the publication of the COMPASS trial, the European Medicines Agency has approved a regimen of combination of rivaroxaban 2.5mg twice daily and a daily dose of 75-100mg acetylsalicylic acid (ASA) for patients with coronary artery disease (CAD) or symptomatic peripheral artery disease (PAD) at high risk of ischemic events. However, the applicability of such a therapeutic strategy in France is currently unknown. AIMS: To describe the proportion of patients eligible to COMPASS in France, their baseline clinical characteristics and the rate of major adverse cardiovascular events, using the REACH registry. METHODS: From the the REduction of Atherothrombosis for Continued Health (REACH) registry database, a large international registry of patients with, or at risk, of atherothrombosis, we analyzed patients included in France with either established CAD and/or PAD and fulfilling the inclusion and exclusion criteria of the COMPASS trial. The ischemic outcome was a composite of cardiovascular (CV) death, myocardial infarction (MI), or stroke, and serious bleeding were defined as haemorrhagic stroke or bleeding leading to hospitalization or transfusion. RESULTS: Among more than 65000 patients enrolled in REACH, 2.012 patients were evaluable and enrolled in France. Among them, 1194 patients (59.3%) were eligible to COMPASS. The main reasons for exclusion of the COMPASS trial, were high bleeding risk (59.1%), anticoagulant use (43.4%), requirement for dual antiplatelet therapy within 1 year of an ACS or PCI (24.7%). In the "COMPASS eligible population", the rate of MACE (CV, MI and stroke) at 4 years follow-up was 13.4% [11.3-15.8], and serious bleeding was 2.5% at 4 years [1.6-3.4]. Patients with polyvascular disease (n=219) had the highest rate of MACE, compared with patients with CAD only and PAD only (19.1% [13.9-26.1] vs. 11.6% [9.1-14.8] vs 13.2% [9.2-18.8], P<0.0001, respectively). CONCLUSION: The COMPASS therapeutic strategy in France appears to be applicable to more than half of CAD or PAD patients. This population appears at high residual risk of atherothrombotic events, and patients with polyvascular disease experienced the highest rate of events.

Frequency of cancer events with saxagliptin in the SAVOR-TIMI 53 trial.

The Saxagliptin Assessment of Vascular Outcomes Recorded in Patients with Diabetes Mellitus (SAVOR)-Thrombolysis in Myocardial Infarction (TIMI) 53 trial randomized trial of 16,492 patients (placebo, n = 8212; saxagliptin, n = 8280) treated and followed for a median of 2.1 years afforded an opportunity to explore whether there was any association with cancer reported as a serious adverse event. At least one cancer event was reported by 688 patients (4.1%): 362 (4.3%) and 326 (3.8%) in the placebo and saxagliptin arms, respectively (p = 0.13). There were 59 (0.6%) deaths adjudicated as malignancy deaths with placebo and 53 (0.6%) with saxagliptin. Stratification by gender, age, race and ethnicity, diabetes duration, baseline glycated haemoglobin and pharmacotherapy did not show any clinically meaningful differences between the two study arms. The overall number of cancer events and malignancy-associated mortality rates were generally balanced between the placebo and saxagliptin groups, suggesting a null relationship with saxagliptin use over the median follow-up of 2.1 years. Multivariable modelling showed that male gender, dyslipidaemia and current smoking were independent predictors of cancer. These randomized data with adequate numbers of cancer cases are reassuring but limited, by the short follow-up in a trial not designed to test this hypothesis.

The effects of proton pump inhibition on patient-reported severity of dyspepsia when receiving dual anti-platelet therapy with clopidogrel and low-dose aspirin: analysis from the Clopidogrel and the Optimization of Gastrointestinal Events Trial.

BACKGROUND: Dual anti-platelet therapy with clopidogrel and low-dose aspirin increases the risk for gastrointestinal clinical events. Omeprazole has been shown to significantly reduce these events without compromising cardiovascular safety in patients treated with dual anti-platelet therapy. Whether or not omeprazole improves patient-reported outcomes is undetermined. AIM: To assess the impact of prophylactic omeprazole with background dual anti-platelet therapy on patient-reported symptoms of dyspepsia compared to placebo. METHODS: We analysed results of the Severity of Dyspepsia Assessment questionnaires collected in the Clopidogrel and the Optimization of Gastrointestinal Events Trial. RESULTS: Patient-reported outcome data from 3759 subjects were available for analysis. At 4 weeks, the mean scores of pain intensity and nonpain symptoms were lower in the omeprazole group (5.61 ± 0.17 vs. 6.40 ± 0.17, P = 0.001, and 10.61 ± 0.07 vs. 11.00 ± 0.07, P < 0.001 respectively). These differences were maintained at 24 weeks (5.91 ± 0.35 vs. 7.10 ± 0.37, P = 0.020 for pain intensity; 10.36 ± 0.12 vs. 10.93 ± 0.13, P = 0.001 for nonpain symptoms). After adjusting for covariates there were no statistically significant differences between the groups in the percent of patients with dyspepsia during follow-up. CONCLUSIONS: In addition to reducing the risk of gastrointestinal bleeding, statistically significant benefits with prophylactic omeprazole use on both pain and nonpain symptoms were evident at 4 weeks and sustained through 24 weeks. The clinical significance of these overall results is unclear, but greater in patients with pain at baseline.

Impact of treatment with saxagliptin on glycaemic stability and ß-cell function in the SAVOR-TIMI 53 study.

AIMS: To study the effects of saxagliptin, a dipeptidyl peptidase-4 inhibitor, on glycaemic stability and ß-cell function in the SAVOR-TIMI 53 trial. METHODS: We randomized 16,492 patients with type 2 diabetes (T2D) to saxagliptin or placebo, added to current antidiabetic medications, and followed them for a median of 2.1 years. Glycaemic instability was defined by: (i) a glycated haemoglobin (HbA1c) increase of ≥ 0.5% post-randomization; (ii) the initiation of new antidiabetic medications for ≥ 3 months; or (iii) an increase in dose of oral antidiabetic medication or ≥ 25% increase in insulin dose for ≥ 3 months. ß-cell function was assessed according to fasting homeostatic model 2 assessment of ß-cell function (HOMA-2ß) values at baseline and at year 2 in patients not treated with insulin. RESULTS: Compared with placebo, participants treated with saxagliptin had a reduction in the development of glycaemic instability (hazard ratio 0.71; 95% confidence interval 0.68-0.74; p < 0.0001). In participants treated with saxagliptin compared with placebo, the occurrence of an HbA1c increase of ≥ 0.5% was reduced by 35.2%; initiation of insulin was decreased by 31.7% and the increases in doses of an oral antidiabetic drug or insulin were reduced by 19.5 and 23.5%, respectively (all p < 0.0001). At 2 years, HOMA-2ß values decreased by 4.9% in participants treated with placebo, compared with an increase of 1.1% in those treated with saxagliptin (p < 0.0001). CONCLUSIONS: Saxagliptin improved glycaemia and prevented the reduction in HOMA-2ß values. Saxagliptin may reduce the usual decline in ß-cell function in T2D, thereby slowing diabetes progression.

The optimal management of patients on oral anticoagulation undergoing coronary artery stenting. The 10th Anniversary Overview.

Even 10 years after the first appearance in the literature of articles reporting on the management of patients on oral anticoagulation (OAC) undergoing percutaneous coronary intervention with stent (PCI-S), this issue is still controversial. Nonetheless, some guidance for the everyday management of this patient subset, accounting for about 5-8 % of all patients referred for PCI-S, has been developed. In general, a period of triple therapy (TT) of OAC, with either vitamin K-antagonists (VKA) or non-vitamin K-antagonist oral anticoagulants (NOAC), aspirin, and clopidogrel is warranted, followed by the combination of OAC, and a single antiplatelet agent for up to 12 months, and then OAC alone. The duration of the initial period of TT is dependent on the individual risk of thromboembolism, and bleeding, as well as the clinical context in which PCI-S is performed (elective vs acute coronary syndrome), and the type of stent implanted (bare-metal vs drug-eluting). In this article, we aim to provide a comprehensive, at-a-glance, overview of the management strategies, which are currently suggested for the peri-procedural, medium-term, and long-term periods following PCI-S in OAC patients. While acknowledging that most of the evidence has been obtained from patients on OAC because of atrial fibrillation, and with warfarin being the most frequently used VKA, we refer in this overview to the whole population of OAC patients undergoing PCI-S. We refer to the whole population of patients on OAC undergoing PCI-S also when OAC is carried out with NOAC rather than VKA, pointing out, when appropriate, the particular management issues.

Attenuated improvements in adiponectin and fat loss characterize type 2 diabetes non-remission status after bariatric surgery.

AIM: To identify the metabolic determinants of type 2 diabetes non-remission status after bariatric surgery at 12 and 24 months. METHODS: A total of 40 adults [mean ± sd body mass index 36 ± 3 kg/m(2) , age 48 ± 9 years, glycated haemoglobin (HbA1c) 9.7 ± 2%) undergoing bariatric surgery [Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG)] were enrolled in the present study, the Surgical Treatment and Medication Potentially Eradicate Diabetes Efficiently (STAMPEDE) trial. Type 2 diabetes remission was defined as HbA1c <6.5% and fasting glucose <126 mg/dl (i.e. <7 mmol/l) without antidiabetic medication. Indices of insulin secretion and sensitivity were calculated from plasma glucose, insulin and C-peptide values during a 120-min mixed-meal tolerance test. Body fat, incretins (glucagon-like polypeptide-1, gastric inhibitory peptide, ghrelin) and adipokines [adiponectin, leptin, tumour necrosis factor-α, high-sensitivity C-reactive protein (hs-CRP)] were also assessed. RESULTS: At 24 months, 37 patients had available follow-up data (RYGB, n = 18; SG, n = 19). Bariatric surgery induced type 2 diabetes remission rates of 40 and 27% at 12 and 24 months, respectively. Total fat/abdominal fat loss, insulin secretion, insulin sensitivity and ß-cell function (C-peptide0-120 /glucose0-120 × Matsuda index) improved more in those with remission at 12 and 24 months than in those without remission. Incretin levels were unrelated to type 2 diabetes remission, but, compared with those without remission, hs-CRP decreased and adiponectin increased more in those with remission. Only baseline adiponectin level predicted lower HbA1c levels at 12 and 24 months, and elevated adiponectin correlated with enhanced ß-cell function, lower triglyceride levels and fat loss. CONCLUSIONS: Smaller rises in adiponectin level, a mediator of insulin action and adipose mass, characterize type 2 diabetes non-remission up to 2 years after bariatric surgery. Adjunctive strategies promoting greater fat loss and/or raising adiponectin may be key to achieving higher type 2 diabetes remission rates after bariatric surgery.

Improved acylated ghrelin suppression at 2 years in obese patients with type 2 diabetes: effects of bariatric surgery vs standard medical therapy.

OBJECTIVE: Roux-en-Y gastric bypass (RYGB) produces more durable glycemic control than sleeve gastrectomy (SG) or intensive medical therapy (IMT). However, the contribution of acylated ghrelin (AG), a gluco-regulatory/appetite hormone, to improve glucose metabolism and body composition in patients with type 2 diabetes (T2D) following RYGB is unknown. DESIGN: STAMPEDE (Surgical Treatment and Medication Potentially Eradicate Diabetes Efficiently) was a prospective, randomized controlled trial. SUBJECTS: Fifty-three (body mass index: 36±3 kg m(-2), age: 49±9 years) poorly controlled patients with T2D (HbA1c (glycated hemoglobin): 9.7±2%) were randomized to IMT, IMT+RYGB or IMT+SG and underwent a mixed-meal tolerance test at baseline, 12, and 24 months for evaluation of AG suppression (postprandial minus fasting) and beta-cell function (oral disposition index; glucose-stimulated insulin secretion × Matsuda index). Total/android body fat (dual-energy X-ray absorptiometry) was also assessed. RESULTS: RYGB and SG reduced body fat comparably (15-23 kg) at 12 and 24 months, whereas IMT had no effect. Beta-cell function increased 5.8-fold in RYGB and was greater than IMT at 24 months (P<0.001). However, there was no difference in insulin secretion between SG vs IMT at 24 months (P=0.32). Fasting AG was reduced fourfold following SG (P<0.01) and did not change with RYGB or IMT at 24 months. AG suppression improved more following RYGB than SG or IMT at 24 months (P=0.01 vs SG, P=0.07 vs IMT). At 24 months, AG suppression was associated with increased postprandial glucagon-like peptide-1 (r=-0.32, P<0.02) and decreased android fat (r=0.38; P<0.006). CONCLUSIONS: Enhanced AG suppression persists for up to 2 years after RYGB, and this effect is associated with decreased android obesity and improved insulin secretion. Together, these findings suggest that AG suppression is partly responsible for the improved glucose control after RYGB surgery.

Geographic differences in outcomes in outpatients with established atherothrombotic disease: results from the REACH Registry.

AIMS: There are major differences in the prevalence and management of patients with atherothrombotic disease including coronary artery disease (CAD), cerebrovascular disease (CVD) and peripheral artery disease (PAD) across different geographical regions. There is, however, little data allowing comparisons of management and outcomes across broad geographic regions. We aimed to describe geographical differences in baseline characteristics, management and outcomes in stable outpatients with established atherothrombotic disease. METHODS AND RESULTS: From the REACH Registry of atherothrombosis, patients with documented CAD, PAD or CVD and with 4-year follow-up were included. Baseline characteristics, treatments and 4-year outcomes were recorded. Event rates were compared between geographical regions and were adjusted for risk scores predicting ischemic and bleeding events. The analyses of baseline characteristics and medications according to geographical region showed marked differences. For the composite primary outcome (cardiovascular death, non-fatal myocardial infarction (MI) and non-fatal stroke), rates ranged from 12.1% in Japan to 18.2% in Eastern Europe. After adjustment, substantial variations remained: taking North America as a reference, patients from Western Europe and Japan had a lower risk of primary outcome event (hazard ratio (HR) 0.93; p = 0.045, and HR = 0.67; p < 0.001 respectively) whereas patients from Eastern Europe had a higher risk (HR = 1.24; p < 0.001). There were no obvious differences between patients from North America and those from Latin America, the Middle East and Asia. CONCLUSION: There are important variations in the outcomes of patients with atherothrombotic across geographic regions. These observations have important implications for public health and clinical research.

Baseline characteristics of the patient population in the Saxagliptin Assessment of Vascular Outcomes Recorded in patients with diabetes mellitus (SAVOR)-TIMI 53 trial.

BACKGROUND AND AIMS: SAVOR-TIMI 53 was designed to study the effects of the DPP-4 inhibitor saxagliptin on cardiovascular outcomes in high risk type 2 diabetes patients with diverse levels of diabetes control and background anti-diabetic drugs. The goal of this article is to describe the baseline characteristics of this hypothesis driven study. MATERIALS AND METHODS: A total of 16 496 diabetic patients from North America (31.9%), Western Europe (26.0%), Eastern Europe (17.3%), Latin America (16.4%) and Asia (8.3%), with either established cardiovascular disease (78.3%) or with ≥two additional cardiovascular risk factors (21.7%) were randomised to saxagliptin or placebo. Biomarkers of inflammation and insulin resistance were taken at baseline and 2 years later in order to correlate saxagliptin effect on cardiovascular outcome to its effect on inflammation and insulin resistance. RESULTS: Mean [+/-standard deviation (SD)] age was 65.0 (+/-8.6) years, 66.9% were male, body mass index was 31.2 kg/m² (+/-5.6), mean diabetes duration was 11.9 years (+/-8.9) and the mean HbA1c 8.0% (+/-1.4%). HbA1c < 7% was most prevalent among North Americans (30.8%) and least among Asians (15.1%), whereas HbA1c > 9% was 30.7% in Latin America 27.0% in Asia and 15.1% in North America. Diabetic retinopathy was reported in 12.3% of patients, nephropathy in 17.7% and amputation in 2.5%. Diabetic treatments categories were as follows: no medication (5.4%), 1 oral anti-diabetic drug (OAD) (25.0%), ≥2 OAD (27.7%) and/or insulin (40.9%). The prevalence of micro-albuminuria was twice as high among insulin users compared with users of ≥2 OAD. Baseline statin use (78.3% overall) varied by region. CONCLUSION: The SAVOR-TIMI 53 patient population, with differing background diabetes control and anti-diabetic treatment, provides global representation of diabetic patients with established cardiovascular disease or at high risk for cardiovascular disease and is well-positioned to determine the effect of saxagliptin on cardiovascular events.

Safety and efficacy of protease-activated receptor-1 antagonists in patients with coronary artery disease: a meta-analysis of randomized clinical trials.

BACKGROUND: Thrombin receptor antagonists blocking protease-activated receptor-1 (PAR-1) on platelets represent a new class of oral antiplatelet agents for patients with atherothrombotic disease manifestations. OBJECTIVES: We investigated the safety and efficacy of PAR-1 antagonists in patients with coronary artery disease (CAD). PATIENTS/METHODS: Randomized, placebo-controlled trials of the PAR-1 antagonists atopaxar or vorapaxar in CAD patients were identified. The primary safety endpoint was the composite of Thrombolysis In Myocardial Infarction (TIMI) clinically significant bleeding. The primary efficacy endpoint was the composite of death, myocardial infarction (MI) or stroke. RESULTS: A total of 41 647 patients from eight trials were included. PAR-1 antagonists were associated with higher risks of TIMI clinically significant (odds ratio [OR] 1.48, 95% confidence interval [CI] 1.39-1.57, P < 0.001), major (OR 1.46, 95% CI 1.28-1.67, P < 0.001) and minor (OR 1.67, 95% CI 1.40-2.00, P < 0.001) bleeding than placebo in the fixed-effects model. PAR-1 antagonists reduced the composite of death, MI or stroke as compared with placebo (OR 0.87, 95% CI 0.81-0.92, P < 0.001), driven by a lower risk of MI (OR 0.85, 95% CI 0.78-0.92, P < 0.001). Conversely, PAR-1 antagonists and placebo did not differ in terms of risk of death (OR 0.99, 95% CI 0.90-1.09, P = 0.81) or stroke (OR 0.96, 95% CI 0.84-1.10, P = 0.59). CONCLUSIONS: PAR-1 antagonists decrease ischemic events in patients with CAD as compared with placebo, mainly driven by a reduction in MI, at the cost of an increased risk of clinically significant bleeding.

P2RY1 and P2RY12 polymorphisms and on-aspirin platelet reactivity in patients with coronary artery disease.

INTRODUCTION: Association of P2RY1 and P2RY12 polymorphisms with on-aspirin platelet reactivity was investigated. MATERIALS AND METHODS: Platelet reactivity was assessed by the light transmission aggregometry and TxB(2) assay in 423 patients with coronary artery disease (CAD) on aspirin. High residual platelet reactivity (RPR) was defined by ≥20% and ≥70% maximal aggregation stimulated with 0.5 mg/mL arachidonic acid (AA) and 10 µm ADP, respectively. Moderate RPR was considered aggregation ≥20% with AA, ≥70% with ADP, or ≥1 ng/mL stimulated TxB(2) . Fourteen P2RY1 and 35 P2RY12 single nucleotide polymorphisms (SNPs) were genotyped. RESULTS: High RPR was detected in 24% of the patients. Moderate RPR was observed in 31% with AA, 57% with 5 µm ADP, and 82% with 10 µm ADP. Stimulated TxB(2) was ≥1 ng/mL in 23% of patients. P2RY12 SNP rs9859538 was associated with high RPR (OR = 2.16, 95% CI = 1.24-3.75, P-value = 0.004). Four P2RY12 SNPs, rs1491974, rs10513398, rs3732765, and rs10935841, showed association with moderate RPR (OR = 1.79-2.94, P-value = 0.04-0.028), while five, rs7615865, rs1388623, rs1388622, rs7634096, and rs7637803, were associated with low RPR (OR = 0.50-0.55, P-value = 0.008-0.026), following ADP stimulation. TxB(2) level <1 ng/mL was linked to five P2RY1 SNPs, rs1439010, rs1371097, rs701265, rs12497578, and rs2312265 (OR = 0.36-0.54, P-value = 0.003-0.039). CONCLUSIONS: Polymorphisms in P2RY1 and P2RY12 are associated with on-aspirin platelet reactivity in patients with CAD.

Two-year vascular hospitalisation rates and associated costs in patients at risk of atherothrombosis in France and Germany: highest burden for peripheral arterial disease.

OBJECTIVES: To obtain Western European perspectives on the economic burden of atherothrombosis in patients with multiple risk factors only (MRF), cerebrovascular disease (CVD), coronary artery disease (CAD), and in the under-evaluated group of patients with peripheral arterial disease (PAD), we examined vascular-related hospitalisation rates and associated costs in France and Germany. DESIGN: The prospective REACH Registry enrolled 4693 patients in France, and 5594 patients in Germany (from December 2003 until June 2004). METHODS: For each country, 2-year rates and costs associated with cardiovascular events and vascular-related hospitalisations were examined for patients with MRF, CVD, CAD, and PAD. RESULTS: Two-year hospitalisation costs were highest for patients with PAD (3182.1€ for France; 2724.4€ for Germany) and lowest for the MRF group (749.1€ for France; 503.3€ for Germany). Peripheral revascularizations and amputations were the greatest contributors to costs for all risk groups. Across all PAD subgroups, peripheral procedures constituted approximately half of the 2-year costs. CONCLUSION: Hospitalisation rates and costs associated with atherothrombotic disease in France and Germany are high, especially so for patients with PAD.

Genetic polymorphisms and the impact of a higher clopidogrel dose regimen on active metabolite exposure and antiplatelet response in healthy subjects.

A double-blind crossover study was conducted in four CYP2C19 genotype-defined metabolizer groups to assess whether increase in clopidogrel dosing can overcome reduced pharmacodynamic response in CYP2C19 poor metabolizers (PMs). Ten healthy subjects in each of four metabolizer groups were randomized to a clopidogrel regimen of a 300-mg loading dose (LD) and a 75-mg/day maintenance dose (MD) for 4 days followed by 600-mg LD and 150 mg/day MD, or vice versa. The exposure levels of clopidogrel's active metabolite H4 (clopi-H4) in PMs were 71% lower on the 75-mg/day regimen and 64% lower on the 150-mg/day regimen than the corresponding exposure levels in extensive metabolizers (EMs). In PMs, the maximal platelet aggregation (MPA) induced by adenosine diphosphate (ADP) 5 µmol/l was 10.5% lower on the 75-mg/day regimen and 7.9% lower on the 150-mg/day regimen than the corresponding values in EMs. PMs who were on the clopidogrel regimen of 600-mg LD/150 mg/day MD showed clopi-H4 exposure and MPA levels similar to those in EMs who were on the regimen of 300-mg LD/75 mg/day MD. In a pooled analysis evaluating CYP1A2, CYP2B6, CYP2C9, CYP2C19, CYP3A5, CYP2D6, ABCB1, and P2RY12 polymorphisms (N = 396 healthy subjects), only CYP2C19 had a significant impact on antiplatelet response. In healthy CYP2C19 PMs, a clopidogrel regimen of 600-mg LD/150 mg/day MD largely overcomes diminished clopi-H4 exposure and antiplatelet response, as assessed by MPA levels.

Risk-factor profile, drug usage and cardiovascular events within a year in patients with and at high risk of atherothrombosis recruited from Asia as compared with those recruited from non-Asian regions: a substudy of the REduction of Atherothrombosis for Continued Health (REACH) registry.

OBJECTIVE: To clarify the differences in the baseline characteristics, prevalence and incidence of atherothrombosis in patients recruited from Asia versus non-Asian regions. DESIGN: International Prospective Cohort Study. SETTING: Region focused substudy. PATIENTS: The Reduction of Atherothrombosis for Continued Health (REACH) Registry recruited 68 236 stable outpatients with established atherothrombosis or ≥3 atherothrombotic risk factors from 44 countries. INTERVENTIONS: No intervention. MAIN OUTCOME MEASURES: Risk factors, use of medications, vascular disease bed location, and 1-year cardiovascular (CV) outcomes (CV death, myocardial infarction, stroke). RESULTS: The percentages of patients recruited with CVD (Cerebrovascular Disease) were higher in Asia (41.0%) than in non-Asian regions (25.1%) (p<0.0001). The prevalence of diabetes mellitus was higher in Asia (46.6%) than in non-Asian regions (43.3%) (p<0.0001) despite the former having a lower body mass index (BMI) (24.4±3.9 vs 28.8±5.6) (p<0.0001). The combined endpoint of CV death/myocardial infarction/stroke of patients recruited from non-Asian regions of 4.38% (95% CI 4.20 to 4.56) is equivalent to those from the Asian region excluding Japan of 4.65% (95% CI 4.04 to 5.25), but that is significantly lower in patients recruited from Japan of 3.40% (95% CI 2.76 to 4.04, p<0.05). CONCLUSIONS: There is a higher prevalence of CVD and higher prevalence of diabetus mellitus with lower body mass index in patients recruited from the Asian region as compared those recruited from non-Asian regions. The CV event rate in patients recruited from non-Asian regions is equivalent to that of patients recruited from the Asian region excluding Japan, but significantly lower in patients recruited from Japan.

Prognosis of atrial fibrillation in patients with symptomatic peripheral arterial disease: data from the REduction of Atherothrombosis for Continued Health (REACH) Registry.

BACKGROUND: Atrial fibrillation (AF) is a significant risk factor for cardiovascular (CV) mortality. This study aims to evaluate the prognostic implication of AF in patients with peripheral arterial disease (PAD). METHODS: The International Reduction of Atherothrombosis for Continued Health (REACH) Registry included 23,542 outpatients in Europe with established coronary artery disease, cerebrovascular disease (CVD), PAD and/or > or =3 risk factors. Of these, 3753 patients had symptomatic PAD. CV risk factors were determined at baseline. Study end point was a combination of cardiac death, non-fatal myocardial infarction (MI) and stroke (CV events) during 2 years of follow-up. Cox regression analysis adjusted for age, gender and other risk factors (i.e., congestive heart failure, coronary artery re-vascularisation, coronary artery bypass grafting (CABG), MI, hypertension, stroke, current smoking and diabetes) was used. RESULTS: Of 3753 PAD patients, 392 (10%) were known to have AF. Patients with AF were older and had a higher prevalence of CVD, diabetes and hypertension. Long-term CV mortality occurred in 5.6% of patients with AF and in 1.6% of those without AF (p<0.001). Multivariable analyses showed that AF was an independent predictor of late CV events (hazard ratio (HR): 1.5; 95% confidence interval (CI): 1.09-2.0). CONCLUSION: AF is common in European patients with symptomatic PAD and is independently associated with a worse 2-year CV outcome.

Worse blood pressure control in patients with cerebrovascular or peripheral arterial disease compared with coronary artery disease.

OBJECTIVES: Poor blood pressure (BP) control is common amongst patients with symptomatic atherothrombotic disease. It is unclear whether BP control and management differ across atherothrombotic disease subtypes. METHODS: We analysed the baseline data of 44,984 patients with documented coronary artery disease (CAD) only (n = 30,414), cerebrovascular disease (CVD) only (n = 11,359) and peripheral arterial disease (PAD) only (n = 3211) from the international REduction of Atherothrombosis for Continued Health Registry and investigated the impact of atherothrombotic disease subtype on BP control and use of antihypertensive drugs. RESULTS: The proportion of patients with BP controlled (<140/90 mmHg) was higher in CAD (58.1%) than in CVD (44.8%) or PAD (38.9%) patients (P < 0.001). Amongst patients with treated hypertension, CAD patients were more likely to have BP controlled than were CVD patients [odds ratio (OR) = 1.67; 95% confidence interval (CI) = 1.59-1.75] or PAD (OR = 2.30; 95% CI = 2.10-2.52). These differences were smaller in women than in men and decreased with age. Amongst treated patients, CAD patients were more likely to receive > or =3-drug combination therapies than were CVD (OR = 1.73; 95% CI = 1.64-1.83) or PAD (OR = 1.64; 95% CI = 1.49-1.80) patients. Adjustment for age, gender, waist obesity, diabetes, education level and world region did not alter the results. CONCLUSIONS: Coronary artery disease patients are more likely than CVD or PAD patients to have BP controlled and to receive antihypertensive drugs, particularly combination therapies. Promotion of more effective BP control through combination antihypertensive therapies could improve secondary prevention and therefore prevent complications in CVD and PAD patients.
