RESUMO

AIM: American and European associations of cardiology published specific guidelines about recommended drugs for secondary prevention in ST-segment elevation myocardial infarction (STEMI) patients. Our aim was to assess whether drug prescription for STEMI patients was in accordance with the guidelines at discharge and after 1 year. METHOD: We used data of 361 patients admitted for STEMI in a tertiary hospital in Switzerland from 2014 to 2016. We assessed the adequacy of prescription of recommended drugs at two time points: discharge and after 1 year. Medications assessed were aspirin, P2Y12 inhibitors, statin, angiotensin-converting enzyme inhibitors (ACEIs)/angiotensin receptor blockers (ARBs) and ß-blockers. We took into account several criteria like statin dosage (low versus high intensity) and presence of contraindication for consideration of optimal therapy. Predictors of incomplete prescription of guideline medications were then assessed with multivariate logistic regression models. RESULTS: From discharge (n = 358) to 1-year follow-up (n = 303), rate of optimal prescription was reduced from 98.6 to 91.7% for aspirin, from 93.9 to 79.1% for P2Y12 inhibitors, from 83.8 to 65.7% for statins, from 98.6 to 95.6% for ACEIs/ARBs, and from 97.1 to 96.9% for ß-blockers. Predictors of incomplete prescription of guideline medications at discharge were female sex (odds ratio [OR] 2.54, p = 0.007), active or former smoker status (OR 2.29, p = 0.017), multivessel disease (OR 2.07, p = 0.022), left ventricular ejection fraction < 40% (OR 2.49, p = 0.008), and transfer to cardiac surgery (OR 9.66, p = 0.018). At 1 year, age > 65 (OR 1.92, p = 0.036) remained the only significant predictor. CONCLUSION: The present study showed a high prescription rate of guideline-recommended medications in a referral center for primary percutaneous coronary intervention. At discharge, women and co-morbid patients were at the highest risk of incomplete prescription of guideline medications, whereas long-term prescription was suboptimal for elderly. A drug lacking at time of discharge was rarely introduced within the year, which underscores the paramount importance of optimal prescription at time of discharge. Strategies like implementing a standardized prescription could reduce the proportion of suboptimal prescription. It could therefore be one way to improve the long-term quality of care of our patients to the highest level. This study used local data from AMIS Plus-National Registry of Acute Myocardial Infarction in Switzerland (NCT01305785).

RESUMO

As usual, numerous papers published in 2017 contributed to optimize the management of patients in all clinical cardiologic fields. It is of course impossible to summarize them all in such an article. Subjects and papers were thus selected if they were thought to be particularly important for non-cardiologist physicians, especially general practitioners. The authors would also like to take the opportunity of this article to honor the memory of Pr Daniel Wagner who unfortunately passed away after less than six months at the head of our Cardiology Department. He was well recognized for his generosity as well as his clinical and scientific competence. This article is dedicated to him.


Comme à l'accoutumée, l'année 2017 a été marquée par la publication de nombreux travaux permettant d'optimaliser la prise en charge de nos patients dans tous les domaines de la cardiologie et il est évidemment impossible de les synthétiser ici de façon exhaustive. Nous avons donc sélectionné les sujets et les travaux qui nous ont paru les plus saillants et surtout les plus utiles pour nos collègues non cardiologues et particulièrement pour nos collègues médecins de premier recours. Cette revue de l'année 2017 ne serait toutefois pas complète sans un hommage au Pr Daniel Wagner qui a débuté son activité de chef du service de cardiologie du CHUV au 1er janvier et nous a quittés après seulement quelques mois passés parmi nous. Daniel fut un chef de service apprécié tant pour ses qualités humaines que pour ses compétences scientifiques et cliniques. Cet article lui est donc dédié.

RESUMO

OBJECTIVES: This study sought to investigate whether early post-infarction cardiac magnetic resonance (CMR) parameters provide additional long-term prognostic value beyond traditional outcome predictors in ST-segment elevation myocardial infarction (STEMI) patients. BACKGROUND: Long-term prognostic significance of CMR in STEMI patients has not been assessed yet. METHODS: This was a longitudinal study from a multicenter registry that prospectively included STEMI patients undergoing CMR after infarction. Between May 2003 and August 2015, 810 revascularized STEMI patients were included. CMR was performed at a median of 4 days after STEMI. Infarct size, microvascular obstruction (MVO), and left ventricular (LV) volumes and function were measured. Primary endpoint was a composite of all death and decompensated heart failure (HF). RESULTS: During median follow-up of 5.5 years (range 1.0 to 13.1 years), primary endpoint occurred in 99 patients (39 deaths and 60 HF hospitalization). MVO was a strong predictor of the composite endpoint after correction for important clinical, CMR, and angiographic parameters, including age, LV systolic function, and infarct size. The independent prognostic value of MVO was confirmed in all multivariate models irrespective of whether it was included as a dichotomous (presence of MVO, hazard ratio [HR]: 1.985 to 1.995), continuous (MVO extent as % LV, HR: 1.095 to 1.097), or optimal cutoff value (MVO extent ≥2.6% of LV; HR: 3.185 to 3.199; p < 0.05 for all). MVO extent ≥2.6% of LV was a strong independent predictor of all death (HR: 2.055; 95% confidence interval: 1.076 to 3.925; p = 0.029) and HF hospitalization (HR: 5.999; 95% confidence interval: 3.251 to 11.069; p < 0.001). Finally, MVO extent ≥2.6% of LV provided incremental prognostic value over traditional outcome predictors (net reclassification improvement index: 0.16 to 0.30; p < 0.05 for all models). CONCLUSIONS: Early post-infarction CMR-based MVO is a strong independent prognosticator in revascularized STEMI patients. Remarkably, MVO extent ≥2.6% of LV improved long-term risk stratification over traditional outcome predictors.

RESUMO

In 2016 the European Society of Cardiology (ESC) published new guidelines. These documents update the knowledge in various fields such as atrial fibrillation, heart failure, cardiovascular prevention and dyslipidemia. Of course it is impossible to summarize these guidelines in detail. Nevertheless, we decided to highlight the major modifications, and to emphasize some key points that are especially useful for the primary care physician.


L'année 2016 en cardiologie a été marquée par la publication de nouvelles recommandations, par la Société européenne de cardiologie (ESC). Ces documents actualisent les connaissances dans des domaines variés que sont la fibrillation auriculaire, l'insuffisance cardiaque, la prévention cardiovasculaire et les dyslipidémies. Il est bien entendu impossible de synthétiser ces recommandations de façon exhaustive. Néanmoins, il nous a paru important de résumer les nouveautés majeures, mais également de rappeler certains points essentiels et surtout utiles pour le médecin de premier recours.

RESUMO

AIMS: MicroRNAs (miRNA) are important non-coding modulators controlling patterns of gene expression. However, profiling and validation of circulating miRNA levels related to adverse cardiovascular outcome has not been performed in patients with an acute coronary syndrome (ACS). METHODS AND RESULTS: In a multicentre, prospective ACS cohort, 1002 out of 2168 patients presented with ST-segment elevation myocardial infarction (STEMI). Sixty-three STEMI patients experienced an adjudicated major cardiovascular event (MACE, defined as cardiac death or recurrent myocardial infarction) within 1 year of follow-up. From a miRNA profiling in a matched derivation case-control cohort, 14 miRNAs were selected for validation. Comparing 63 cases vs. 126 controls, 3 miRNAs were significantly differentially abundant. In patients with MACE, miR-26b-5p levels (P = 0.038) were decreased, whereas miR-320a (P = 0.047) and miR-660-5p (P = 0.01) levels were increased. MiR-26b-5p has been suggested to prevent adverse cardiomyocyte hypertrophy, whereas miR-320a promotes cardiomyocyte death and apoptosis, and miR-660-5p has been related to active platelet production. This suggests that miR-26b-5p, miR-320a, and miR-660-5p may reflect alterations of different pathophysiological pathways involved in clinical outcome after ACS. Consistently, these three miRNAs reliably discriminated cases from controls [area under the receiver-operating characteristic curve (AUC) in age- and sex-adjusted Cox regression for miR-26b-5p = 0.707, miR-660-5p = 0.683, and miR-320a =0.672]. Combination of the three miRNAs further increased AUC to 0.718. Importantly, addition of the three miRNAs to both, the Global Registry of Acute Coronary Events (GRACE) score and a clinical model increased AUC from 0.679 to 0.720 and 0.722 to 0.732, respectively, with a net reclassification improvement of 0.20 in both cases. CONCLUSION: This is the first study performing profiling and validation of miRNAs that are associated with adverse cardiovascular outcome in patients with STEMI. MiR-26b-5p, miR-320a, and miR-660-5p discriminated for MACE and increased risk prediction when added to the GRACE score and a clinical model. These findings suggest that the release of specific miRNAs into circulation may reflect the activation of molecular pathways that impact on clinical outcome after STEMI.

RESUMO

Mitral regurgitation (MR) is the most frequent valvular disease in industrialised countries. MR is classified as primary (mostly degenerative with valve prolapse) or secondary (mainly due to underlying ischemic heart disease resulting in deformation of the valve structure). Surgical repair represents the optimal treatment for severe primary MR, whereas the benefits of surgical correction of secondary MR are controversial. Over the past few years, transcatheter techniques have been developed to treat MR, such as the percutaneous edge-to-edge procedure (MitraClip). These approaches represent a novel therapeutic choice for patients judged inoperable by the "heart team". This review article aims to summarize the principles of MR assessment and discuss current therapeutic options for severe MR, taking into account the latest advances in the field.

RESUMO

The present review provides a selected choice of clinical trials and therapeutic advances in the field of cardiology in 2015. A new treatment option in heart failure will become available this year in Switzerland. In interventional cardiology, new trials have been published on the duration of dual antiplatelet therapy, the new stents with bioresorbable scaffold and the long-term results of TAVR in patients who are not surgical candidates or at high surgical risk. RegardingAF the BRIDGE trial provides new evidences to guide the management of patients during warfarin interruption for surgery. Recent publications are changing the paradigm of AF treatment by showing a major impact of the management of cardiometabolic risk factors. Finally, refined criteria for ECG interpretation in athletes have been recently proposed to reduce the burden of false-positive screening.

RESUMO

AIMS: We aimed to assess the prevalence and management of clinical familial hypercholesterolaemia (FH) among patients with acute coronary syndrome (ACS). METHODS AND RESULTS: We studied 4778 patients with ACS from a multi-centre cohort study in Switzerland. Based on personal and familial history of premature cardiovascular disease and LDL-cholesterol levels, two validated algorithms for diagnosis of clinical FH were used: the Dutch Lipid Clinic Network algorithm to assess possible (score 3-5 points) or probable/definite FH (>5 points), and the Simon Broome Register algorithm to assess possible FH. At the time of hospitalization for ACS, 1.6% had probable/definite FH [95% confidence interval (CI) 1.3-2.0%, n = 78] and 17.8% possible FH (95% CI 16.8-18.9%, n = 852), respectively, according to the Dutch Lipid Clinic algorithm. The Simon Broome algorithm identified 5.4% (95% CI 4.8-6.1%, n = 259) patients with possible FH. Among 1451 young patients with premature ACS, the Dutch Lipid Clinic algorithm identified 70 (4.8%, 95% CI 3.8-6.1%) patients with probable/definite FH, and 684 (47.1%, 95% CI 44.6-49.7%) patients had possible FH. Excluding patients with secondary causes of dyslipidaemia such as alcohol consumption, acute renal failure, or hyperglycaemia did not change prevalence. One year after ACS, among 69 survivors with probable/definite FH and available follow-up information, 64.7% were using high-dose statins, 69.0% had decreased LDL-cholesterol from at least 50, and 4.6% had LDL-cholesterol ≤1.8 mmol/L. CONCLUSION: A phenotypic diagnosis of possible FH is common in patients hospitalized with ACS, particularly among those with premature ACS. Optimizing long-term lipid treatment of patients with FH after ACS is required.

RESUMO

OBJECTIVE: To assess recommended and actual use of statins in primary prevention of cardiovascular disease (CVD) based on clinical prediction scores in adults who develop their first acute coronary syndrome (ACS). METHOD: Cross-sectional study of 3172 adults without previous CVD hospitalized with ACS at 4 university centers in Switzerland. The number of participants eligible for statins before hospitalization was estimated based on the European Society of Cardiology (ESC) guidelines and compared to the observed number of participants on statins at hospital entry. RESULTS: Overall, 1171 (37%) participants were classified as high-risk (10-year risk of cardiovascular mortality ≥5% or diabetes); 1025 (32%) as intermediate risk (10-year risk <5% but ≥1%); and 976 (31%) as low risk (10-year risk <1%). Before hospitalization, 516 (16%) were on statins; among high-risk participants, only 236 of 1171 (20%) were on statins. If ESC primary prevention guidelines had been fully implemented, an additional 845 high-risk adults (27% of the whole sample) would have been eligible for statins before hospitalization. CONCLUSION: Although statins are recommended for primary prevention in high-risk adults, only one-fifth of them are on statins when hospitalized for a first ACS.

RESUMO

Important clinical trials and therapeutic advances in the field of cardiology have been presented in 2014. New evidences on the management of acute myocardial infarction and the duration of dual antiplatelet therapy after coronary stent implantation have been published. A new class of therapeutic agents seems to offer promising perspectives for patients with heart failure and reduced ejection fraction. The new generation of subcutaneous or MRI-compatible implantable defibrillators is a major technological breakthrough. Finally, the European Society of Cardiology published new recommendations for the management of patients with cardiovascular diseases. This selective review of the literature summarizes the most important studies in the field of interventional cardiology, rhythmology, heart failure and cardiac imaging.

RESUMO

OBJECTIVE: To assess safety up to 1 year of follow-up associated with prasugrel and clopidogrel use in a prospective cohort of patients with acute coronary syndromes (ACS). METHODS: Between 2009 and 2012, 2286 patients invasively managed for ACS were enrolled in the multicentre Swiss ACS Bleeding Cohort, among whom 2148 patients received either prasugrel or clopidogrel according to current guidelines. Patients with ST-elevation myocardial infarction (STEMI) preferentially received prasugrel, while those with non-STEMI, a history of stroke or transient ischaemic attack, age ≥75 years, or weight <60 kg received clopidogrel or reduced dose of prasugrel to comply with the prasugrel label. RESULTS: After adjustment using propensity scores, the primary end point of clinically relevant bleeding events (defined as the composite of Bleeding Academic Research Consortium, BARC, type 3, 4 or 5 bleeding) at 1 year, occurred at a similar rate in both patient groups (prasugrel/clopidogrel: 3.8%/5.5%). Stratified analyses in subgroups including patients with STEMI yielded a similar safety profile. After adjusting for baseline variables, no relevant differences in major adverse cardiovascular and cerebrovascular events were observed at 1 year (prasugrel/clopidogrel: cardiac death 2.6%/4.2%, myocardial infarction 2.7%/3.8%, revascularisation 5.9%/6.7%, stroke 1.0%/1.6%). Of note, this study was not designed to compare efficacy between prasugrel and clopidogrel. CONCLUSIONS: In this large prospective ACS cohort, patients treated with prasugrel according to current guidelines (ie, in patients without cerebrovascular disease, old age or underweight) had a similar safety profile compared with patients treated with clopidogrel. CLINICAL TRIAL REGISTRATION NUMBER: SPUM-ACS: NCT01000701; COMFORTABLE AMI: NCT00962416.

RESUMO

BACKGROUND: 2013 AHA/ACC guidelines on the treatment of cholesterol advised to tailor high-intensity statin after ACS, while previous ATP-III recommended titration of statin to reach low-density lipoprotein cholesterol (LDL-C) targets. We simulated the impact of this change of paradigm on the achievement of recommended targets. METHODS: Among a prospective cohort study of consecutive patients hospitalized for ACS from 2009 to 2012 at four Swiss university hospitals, we analyzed 1602 patients who survived one year after recruitment. Targets based on the previous guidelines approach was defined as (1) achievement of LDL-C target < 1.8 mmol/l, (2) reduction of LDL-C ≥ 50% or (3) intensification of statin in patients who did not reach LDL-C targets. Targets based on the 2013 AHA/ACC guidelines approach was defined as the maximization of statin therapy at high-intensity in patients aged ≤75 years and moderate- or high-intensity statin in patients >75 years. RESULTS: 1578 (99%) patients were prescribed statin at discharge, with 1120 (70%) at high-intensity. 1507 patients (94%) reported taking statin at one year, with 909 (57%) at high-intensity. Among 482 patients discharged with sub-maximal statin, intensification of statin was only observed in 109 patients (23%). 773 (47%) patients reached the previous LDL-C targets, while 1014 (63%) reached the 2013 AHA/ACC guidelines targetsone year after ACS (p value < 0.001). CONCLUSION: The application of the new 2013 AHA/ACC guidelines criteria would substantially increase the proportion of patients achieving recommended lipid targets one year after ACS. Clinical trial number, NCT01075868.

RESUMO

BACKGROUND: The prescription of recommended medical therapies is a key factor to improve prognosis after acute coronary syndromes (ACS). However, reasons for cardiovascular therapies discontinuation after hospital discharge are poorly reported in previous studies. METHODS: We enrolled 3055 consecutive patients hospitalized with a main diagnosis of ACS in four Swiss university hospitals with a prospective one-year follow-up. We assessed the self-reported use of recommended therapies and the reasons for medication discontinuation according to the patient interview performed at one-year follow-up. RESULTS: 3014 (99.3%) patients were discharged with aspirin, 2983 (98.4%) with statin, 2464 (81.2%) with beta-blocker, 2738 (90.3%) with ACE inhibitors/ARB and 2597 (100%) with P2Y12 inhibitors if treated with coronary stent. At the one-year follow-up, the discontinuation percentages were 2.9% for aspirin, 6.6% for statin, 11.6% for beta-blocker, 15.1% for ACE inhibitor/ARB and 17.8% for P2Y12 inhibitors. Most patients reported having discontinued their medication based on their physicians' decision: 64 (2.1%) for aspirin, 82 (2.7%) for statin, 212 (8.6%) for beta-blocker, 251 (9.1% for ACE inhibitor/ARB) and 293 (11.4%) for P2Y12 inhibitors, while side effect, perception that medication was unnecessary and medication costs were uncommon reported reasons (<2%) according to the patients. CONCLUSIONS: Discontinuation of recommended therapies after ACS differs according the class of medication with the lowest percentages for aspirin. According to patients, most stopped their cardiovascular medication based on their physician's decision, while spontaneous discontinuation was infrequent.

RESUMO

BACKGROUND: In heart transplantation, antibody-mediated rejection (AMR) is diagnosed and graded on the basis of immunopathologic (C4d-CD68) and histopathologic criteria found on endomyocardial biopsies (EMB). Because some pathologic AMR (pAMR) grades may be associated with clinical AMR, and because humoral responses may be affected by the intensity of immunosuppression during the first posttransplantation year, we investigated the incidence and positive predictive values (PPV) of C4d-CD68 and pAMR grades for clinical AMR as a function of time. METHODS: All 564 EMB from 40 adult heart recipients were graded for pAMR during the first posttransplantation year. Clinical AMR was diagnosed by simultaneous occurrence of pAMR on EMB, donor specific antibodies and allograft dysfunction. RESULTS: One patient demonstrated clinical AMR at postoperative day 7 and one at 6 months (1-year incidence 5%). C4d-CD68 was found on 4,7% EMB with a "decrescendo" pattern over time (7% during the first 4 months vs. 1.2% during the last 8 months; P < 0.05). Histopathologic criteria of AMR occurred on 10.3% EMB with no particular time pattern. Only the infrequent (1.4%) pAMR2 grade (simultaneous histopathologic and immunopathologic markers) was predictive for clinical AMR, particularly after the initial postoperative period (first 4 months and last 8 months PPV = 33%-100%; P < 0.05). CONCLUSION: In the first posttransplantation year, AMR immunopathologic and histopathologic markers were relatively frequent, but only their simultaneous occurrence (pAMR2) was predictive of clinical AMR. Furthermore, posttransplantation time may modulate the occurrence of C4d-CD68 on EMB and thus the incidence of pAMR2 and its relevance to the diagnosis of clinical AMR.

RESUMO

BACKGROUND: Adherence to guidelines is associated with improved outcomes of patients with acute coronary syndrome (ACS). Clinical registries developed to assess quality of care at discharge often do not collect the reasons for non-prescription for proven efficacious preventive medication in Continental Europe. In a prospective cohort of patients hospitalized for an ACS, we aimed at measuring the rate of recommended treatment at discharge, using pre-specified quality indicators recommended in cardiologic guidelines and including systematic collection of reasons for non-prescription for preventive medications. METHODS: In a prospective cohort with 1260 patients hospitalized for ACS, we measured the rate of recommended treatment at discharge in 4 academic centers in Switzerland. Performance measures for medication at discharge were pre-specified according to guidelines, systematically collected for all patients and included in a centralized database. RESULTS: Six hundred and eighty eight patients(54.6%) were discharged with a main diagnosis of STEMI, 491(39%) of NSTEMI and 81(6.4%) of unstable angina. Mean age was 64 years and 21.3% were women. 94.6% were prescribed angiotensin converting enzyme inhibitors/angiotensin II receptor blockers at discharge when only considering raw prescription rates, but increased to 99.5% when including reasons non-prescription. For statins, rates increased from 98% to 98.6% when including reasons for non-prescription and for beta-blockers, from 82% to 93%. For aspirin, rates further increased from 99.4% to 100% and from to 99.8% to 100% for P2Y12 inhibitors. CONCLUSIONS: We found a very high adherence to ACS guidelines for drug prescriptions at discharge when including reasons for non-prescription to drug therapy. For beta-blockers, prescription rates were suboptimal, even after taking into account reason for non-prescription. In an era of improving quality of care to achieve 100% prescription rates at discharge unless contra-indicated, pre-specification of reasons for non-prescription for cardiovascular preventive medication permits to identify remaining gaps in quality of care at discharge. TRIAL REGISTRATION: ClinicalTrials.gov NCT01000701.

RESUMO

We herein report the case of a 36-year-old man who died suddenly after a fight with another man. Forensic investigations included unenhanced computed tomography, postmortem angiography, autopsy, histology, neuropathology, toxicology, and biochemistry and allowed a traumatic cause of death to be excluded. An electrocardiogram recorded some years prior to death revealed the presence of an early repolarization pattern. Based on the results of all investigations, the cause of death was determined to be cardiac arrhythmia and cardiac arrest during an emotionally stressful event associated with physical assault. Direct third party involvement, however, was excluded, and the manner of death was listed as natural. The case was not pursued any further by the public prosecutor.

RESUMO

OBJECTIVES: To test if the time of day significantly influences the occurrence of type 4A myocardial infarction in elective patients undergoing percutaneous coronary intervention (PCI). BACKGROUND: Recent studies have suggested an influence of circadian rhythms on myocardial infarction size and mortality among patients with ST-elevation myocardial infarction. The aim of the study is to investigate whether periprocedural myocardial infarction (PMI) is influenced by the time of day in elective patients undergoing PCI. METHODS: All consecutive patients undergoing elective PCI between 2007 and 2011 at our institutions with known post-interventional troponin were retrospectively included. Patients (n = 1021) were divided into two groups according to the starting time of the PCI: the morning group (n = 651) between 07:00 and 11:59, and the afternoon group (n = 370) between 12:00 and 18:59. Baseline and procedural characteristics as well as clinical outcome defined as the occurrence of PMI were compared between groups. In order to limit selection bias, all analyses were equally performed in 308 pairs using propensity score (PS) matching. RESULTS: In the overall population, the rate of PMI was statistically lower in the morning group compared to the afternoon group (20% vs. 30%, p < 0.001). This difference remained statistically significant after PS-matching (21% vs. 29%, p = 0.03). Multivariate analysis shows that being treated in the afternoon independently increases the risk for PMI with an odds ratio of 2.0 (95%CI: 1.1-3.4; p = 0.02). CONCLUSIONS: This observational PS-matched study suggests that the timing of an elective PCI influences the rate of PMI.

RESUMO

Aortic stenosis mostly occurs among old-old patients. Once symptoms appear, prognosis is guarded, with 2-year mortality as high as 50%. Transcatheter Aortic Valve Implantation (TAVI) is a new therapeutic option in patients at very high surgical risk, who are mostly older persons. However, TAVI is associated with some complications, and patient selection remains a challenge. Comprehensive geriatric assessment (CGA) identifies patients with medical and functional problems likely to affect the TAVI post-operative course. Collaboration between cardiologists and geriatricians will likely become a standard approach to enhance the assessment of these frail patients and identify those most likely to benefit from TAVI.

RESUMO

Ultrasound detection of sub-clinical atherosclerosis (ATS) may help identify individuals at high cardiovascular risk. Most studies evaluated intima-media thickness (IMT) at carotid level. We compared the relationships between main cardiovascular risk factors (CVRF) and five indicators of ATS (IMT, mean and maximal plaque thickness, mean and maximal plaque area) at both carotid and femoral levels. Ultrasound was performed on 496 participants aged 45-64 years randomly selected from the general population of the Republic of Seychelles. 73.4 % participants had ≥ 1 plaque (IMT thickening ≥ 1.2 mm) at carotid level and 67.5 % at femoral level. Variance (adjusted R2) contributed by age, sex and CVRF (smoking, LDL-cholesterol, HDL-cholesterol, blood pressure, diabetes) in predicting any of the ATS markers was larger at femoral than carotid level. At both carotid and femoral levels, the association between CVRF and ATS was stronger based on plaque-based markers than IMT. Our findings show that the associations between CVRF and ATS markers were stronger at femoral than carotid level, and with plaque-based markers rather than IMT. Pending comparison of these markers using harder cardiovascular endpoints, our findings suggest that markers based on plaque morphology assessed at femoral artery level might be useful cardiovascular risk predictors.
