Abstract
Abstract
Background
Previous studies using experimental models and clinical retrospective samples have pointed to a potential role of glycosylated apolipoprotein J (ApoJ-Glyc) as a marker for the early detection of myocardial ischaemia. Ischaemia induces intracellular accumulation of non-glycosylated ApoJ that mirrors the reduction in ApoJ-Glyc serum levels in patients presenting with ST-segment elevation myocardial infarction (STEMI).
Purpose
The EDICA (Early Detection of Myocardial Ischaemia in Suspected Acute Coronary Syndromes by Apo J-Glyc as a Novel Pathologically based Ischaemia Biomarker) clinical trial assessed the performance of ApoJ-Glyc as a biomarker for the early detection of myocardial ischaemia in patients attending the A&E department with chest pain suggestive of acute coronary syndrome. Here, we report the observed changes in ApoJ-Glyc concentration in STEMI patients at baseline and after primary percutaneous coronary intervention (PPCI).
Methods
The EDICA trial, a multi-centre (10 sites), international, in vitro diagnostic study, assessed 404 patients attending the A&E department with suspected ACS. Of these, 291 patients had a final diagnosis of “non-ischaemic” event and 113 of “ischaemic” event. The main inclusion criterion was chest pain of suspected cardiac origin. Blood samples were obtained for the simultaneous assessment of high sensitivity-troponin and ApoJ-Glyc on admission (time 0) and at 1h and 3h thereafter. Two different glycosylated variants of ApoJ (ApoJ-GlycA2 and ApoJ-GlycA6) were analyzed with a novel ELISA in serum samples. Of the “ischaemic” patients, 33 had STEMI, of whom 85% underwent PPCI.
Results
As expected, in the presence of myocardial ischaemia, time 0 ApoJ-GlycA2 and ApoJ-GlycA6 serum levels decreased by 34% and 48%, respectively in STEMI patients, compared with non-ischaemic patients, i.e. ApoJ-GlycA2 in STEMI: 66 [52–95] μg/ml vs. non-ischaemic: 100 [72–131] μg/ml; P=0.0002; ApoJ-GlycA6 STEMI: 38 [34–67] vs. non-ischaemic: 73 [56–95] μg/ml; P<0.0001. ApoJ-GlycA6 showed a discriminating ability for the presence of STEMI with a 67% sensitivity and a 83% specificity (AUC=0.747, cut-off of 50μg/ml). In STEMI patients in whom PPCI successfully restored TIMI 3 flow, ApoJ-Glyc levels increased rapidly and significantly compared with time 0 levels (ApoJ-GlycA2: P=0.02 and P=0.003 for 1h and 3h; ApoJ-GlycA6: P=0.02 and P=0.002 for 1h and 3h) and compared to patients in whom PPCI was not performed (Table 1).
Conclusions
ApoJ-Glyc concentrations are reduced in STEMI patients on admission and increase rapidly after improved perfusion with PPCI, pointing to a potential role of this biomarker in the early detection of reversible ischaemia and the mapping of reversible changes. The mechanisms whereby ApoJ-Glyc levels rapidly and markedly increase after PPCI are speculative at present and deserve further investigation, together with the potential prognostic value of ApoJ-Glyc in this setting.

Abstract
Abstract
Background
There is limited literature available on the impact of myocardial ischemia but no obstructive coronary arteries (INOCA) on patients' lives.
Purpose
We sought to determine how INOCA impacts the physical, social, and mental health of persons with this diagnosis.
Methods
A survey was made available to all members of the patient support group from INOCA International over a 3-month time period. Fitness was estimated using the Duke Activity Status Index (DASI), assessing levels of activities performed prior to the onset of INOCA symptoms, and after the diagnosis of INOCA. The formula to estimate fitness in metabolic equivalents (METs) = 0.43 × DASI + 9.6 / 3.5
Results
A total of 297 patients with INOCA responded to the survey; 91.2% were women. The most common diagnosis was coronary microvascular dysfunction (64.3%) and coronary artery spasm (50.5%) (Table 1). 34.4% reported living with symptoms for ≥3 years before their diagnosis of INOCA was made. 77.8% who had been told their symptoms were not cardiac. The symptoms the respondents experienced were numerous, but 92.9% reported symptoms of chest pain, pressure, or discomfort. Fitness levels prior to the onset of INOCA symptoms were significantly higher compared to after diagnosed with INOCA (8.6±1.8 METs vs 5.6±1.8 METs; P<0.0001). Most respondents reported an adverse impact on their home life (80.5%), social life (80.1%), mental health (70.4%), outlook on life (69.7%), sex life (55.9%), and their partner/spouse relationship (53.9%). Work life was also affected once living with INOCA: approximately three-quarters had reduced their work hours or stopping work completely, 47.5% retired early, and 38.4% applied for disability. While living with INOCA, for each 1-MET decrease in fitness, there was a loss of 3.0±0.6 days/months of physical health, 1.8±0.6 days/month of mental health, and 2.9±0.7 days/months of inability to perform recreational activities (p<0.0001) (Figure 1).
Conclusions
Living with INOCA has significant impact on physical, mental and social health. Significant physical fitness declines are seen in those living with INOCA and are lower in those experiencing any adverse impact of living with INOCA. Additionally, the impact of INOCA on the ability to work has important economic consequences to both the patient and society. Increased recognition of the impact of INOCA on these aspects of health need to be recognized and further work is needed to better diagnosis and treat the symptoms of INOCA to improve the quality of life, cardiovascular outcomes, and overall health of this frequently encountered cardiovascular disorder.

Abstract
Pharmacogenomics promises to advance cardiovascular therapy, but there remain pragmatic barriers to implementation. These are particularly important to explore within Europe, as there are differences in the populations, availability of resources and expertise, as well as in ethico-legal frameworks. Differences in healthcare delivery across Europe present a challenge, but also opportunities to collaborate on PGx implementation. Clinical work force upskilling is already in progress but will require substantial input. Digital infrastructure and clinical support tools are likely to prove crucial. It is important that widespread implementation serves to narrow rather than widen any existing gaps in health equality between populations. This viewpoint supplements the working group position paper on cardiovascular pharmacogenomics to address these important themes.

Abstract
There is a strong and ever-growing body of evidence regarding the use of pharmacogenomics to inform cardiovascular pharmacology. However, there is no common position taken by international cardiovascular societies to unite diverse availability, interpretation and application of such data, nor is there recognition of the challenges of variation in clinical practice between countries within Europe. Aside from the considerable barriers to implementing pharmacogenomic testing and the complexities of clinically actioning results, there are differences in the availability of resources and expertise internationally within Europe. Diverse legal and ethical approaches to genomic testing and clinical therapeutic application also require serious thought. As direct-to-consumer genomic testing becomes more common, it can be anticipated that data may be brought in by patients themselves, which will require critical assessment by the clinical cardiovascular prescriber. In a modern, pluralistic and multi-ethnic Europe, self-identified race/ethnicity may not be concordant with genetically detected ancestry and thus may not accurately convey polymorphism prevalence. Given the broad relevance of pharmacogenomics to areas such as thrombosis and coagulation, interventional cardiology, heart failure, arrhythmias, clinical trials, and policy/regulatory activity within cardiovascular medicine, as well as to genomic and pharmacology subspecialists, this position statement attempts to address these issues at a wide-ranging level.

Abstract
Pharmacogenomics has a burgeoning role in cardiovascular medicine, from warfarin dosing to antiplatelet choice, with recent developments in sequencing bringing the promise of personalised medicine ever closer to the bedside. Further scientific evidence, real-world clinical trials, and economic modelling are needed to fully realise this potential. Additionally, tools such as polygenic risk scores, and results from Mendelian randomisation analyses, are only in the early stages of clinical translation and merit further investigation. Genetically targeted rational drug design has a strong evidence base and, due to the nature of genetic data, academia, direct-to-consumer companies, healthcare systems, and industry may meet in an unprecedented manner. Data sharing navigation may prove problematic. The present manuscript addresses these issues and concludes a need for further guidance to be provided to prescribers by professional bodies to aid in the consideration of such complexities and guide translation of scientific knowledge to personalised clinical action, thereby striving to improve patient care. Additionally, technologic infrastructure equipped to handle such large complex data must be adapted to pharmacogenomics and made user friendly for prescribers and patients alike.

Abstract
Cardiovascular event rates are high in patients with chronic kidney disease (CKD), increasing with deteriorating kidney function, highest in CKD patients on dialysis, and improve with kidney transplantation (KTx). The cardiovascular events in CKD patients such as myocardial infarction and heart failure are related to abnormalities of vascular and cardiac structure and function. Many studies have investigated the structural and functional abnormalities of the heart and blood vessels in CKD, and the changes that occur with KTx, but the evidence is often sparse and occasionally contradictory. We have reviewed the available evidence and identified areas where more research is required to improve the understanding and mechanisms of these changes. There is enough evidence demonstrating improvement of left ventricular hypertrophy, except in children, and sufficient evidence of improvement of left ventricular function, with KTx. There is reasonable evidence of improvement in vascular function and stiffness. However, the evidence for improvement of vascular structure and atherosclerosis is insufficient. Further studies are necessary to establish the changes in vascular structure, and to understand the mechanisms of vascular and cardiac changes, following KTx.

Abstract
Background: Head and neck cancers (HNC) are aggressive tumours. Overexpression of p16 in HNC correlates with human papilloma virus (HPV)-associated HNC that carry a better prognosis than HPV-negative tumours. Angiogenesis is an important factor in tumour progression. Our aim was to dissect the impact of p16 expression on angiogenesis factors in HNC. Methods: Eighteen newly diagnosed HNC patients and controls were analysed. Eleven pro- and anti-angiogenesis factors were quantified using multiplex ELISA in HNC patients and controls. Angiogenesis factors were analysed in tumour tissue using immunohistochemistry. Results: Circulating levels of endostatin (anti-angiogenesis factor) were higher in the HNC group compared with healthy donors. Interestingly, the pro-angiogenesis factors angiopoietin-1 and vascular endothelial growth factor (VEGF) were significantly higher in patients with p16-negative compared with p16-positive HNC. Moreover, the major source of VEGF in p16-positive HNC tissue was tumour stromal cells. In contrast, both tumour cells and stromal cells expressed VEGF in p16-negative tissue. Conclusions: We show that p16-negative tumours associate with increased circulating levels of pro-angiogenic VEGF and angiopoietin-1. Tissue expression of VEGF differs between p16-positive and p16-negative tumours. These findings may explain differences in the biological behaviour of p16-positive and p16-negative HNC. Better understanding of mechanisms by which the p16 status influences tumour angiogenesis may guide the development of targeted therapies.

Abstract
BACKGROUND Endothelial dysfunction is a marker of future cardiovascular disease (CVD) risk, yet epidemiological studies have yielded inconsistent results. We therefore studied the association between endothelial dysfunction and CVD under diverse circumstances. METHODS AND RESULTS Literature-based meta-analysis of prospective observational studies with ≥ 12 months of follow-up published in Medline and having information on endothelial function and CVD outcomes. Tabular data on participant characteristics, endothelial function assessments and incident CVD outcomes were abstracted from individual studies. Random-effects meta-analysis was used to quantify pooled associations, and I(2) statistic to evaluate between-study heterogeneity. Potential sources of heterogeneity were explored by subgroup analyses and meta-regression. Thirty five studies involving 17,206 participants met the inclusion criteria. During more than 80,000 person-years of observation, up to 2755 CVD events were accrued, yielding a pooled relative risk (RR) of 1.25 (95% confidence interval 1.15-1.35) for CVD comparing top (i.e. more severe) vs. bottom (less severe) third of endothelial dysfunction. There was significant between-study heterogeneity and evidence of publication bias. RRs varied importantly according to the method used to ascertain endothelial function, and were higher among older individuals and among participants with risk factors for CVD or established CVD at baseline. CONCLUSIONS Although endothelial dysfunction is an important determinant of cardiovascular outcomes in people with pre-existing CVD, current evidence base does not support its use as a potentially useful measurement for risk stratification in people at lower risk of CVD.

Abstract
BACKGROUND AND OBJECTIVES Whilst traditional studies have shown that obese individuals are at a higher risk of cardiovascular events compared to lean subjects, recent studies in patients with acute myocardial infarction (AMI) have suggested that obesity may exert protective effects (the "obesity paradox"). We sought to assess the relationship between body mass index (BMI) and the BARI score (BARIsc), a validated tool used to assess myocardium at risk, in patients with acute coronary syndrome. PATIENTS AND METHODS Participants were 116 consecutive patients (mean age, 60.6 years; 97 men) with AMI (68 ST elevated myocardial infarction, STEMI; 48 non-ST elevated myocardial infarction, NSTEMI). Demographics, BMI, risk factors, biochemistry data, left ventricular function, angiographic data and the BARIsc were assessed in every patient. RESULTS Multiple linear regression analyses showed that BMI significantly correlated with BARIsc; β=.23, p<0.02. This was found only in the overweight/obese patients, β=.27, p<0.01, but not in patients with normal BMIs, β=0.08, p=0.71. CONCLUSIONS An increased body weight is associated with an increased area of myocardium at risk in patients with ACS.

Abstract
BACKGROUND The determinants of depression following acute coronary syndrome (ACS) are poorly understood. Triggering of ACS by emotional stress and low socio-economic status (SES) are predictors of adverse outcomes. We therefore investigated whether emotional triggering and low SES predict depression and anxiety following ACS. METHOD This prospective observational clinical cohort study involved 298 patients with clinically verified ACS. Emotional stress was assessed for the 2 h before symptom onset and compared with the equivalent period 24 h earlier using case-crossover methods. SES was defined by household income and education. Depression was measured with the Beck Depression Inventory and the Hamilton Rating Scale for Depression and anxiety with the Hospital Anxiety and Depression Scale 3 weeks after ACS and again at 6 and 12 months. Age, gender, ethnicity, marital status, the Global Registry of Acute Coronary Events risk score, duration of hospital stay and history of depression were included as covariates. RESULTS Emotional stress during the 2-h hazard period was associated with increased risk of ACS (odds ratio 1.88, 95% confidence interval 1.01-3.61). Both low income and emotional triggering predicted depression and anxiety at 3 weeks and 6/12 months independently of covariates. The two factors interacted, with the greatest depression and anxiety in lower income patients who experienced acute emotional stress. Education was not related to depression. CONCLUSIONS Patients who experience acute emotional stress during their ACS and are lower SES as defined by current affluence and access to resources are particularly vulnerable to subsequent depression and anxiety.

Abstract
Increasing knowledge of the atherosclerotic process, as well as atherosclerotic plaque composition and morphology, has lead to the identification of vulnerable plaques that lead to acute coronary syndromes. There is growing evidence for atherosclerotic plaque regression, which makes an aggressive targeted therapeutic response based on achieving plaques regression necessary in order to reduce the significant mortality and morbidity associated with coronary heart disease. This review will examine the evidence for atherosclerotic plaque regression, the important role of statins and the available imaging techniques used to investigate this condition. We will also discuss future evolving therapies and possible predictors of plaque regression, which may aid the therapeutic process.

Abstract
BACKGROUND Risk stratification of patients with unstable angina or non-ST-segment elevation myocardial infarction (UA/NSTEMI) is problematic given the heterogeneous presentation of the condition. This study was undertaken to compare, in UA/NSTEMI patients, the prognostic value of two clinical risk scores (RS) (i.e. Thrombolysis in Myocardial Infarction (TIMI) and physician's risk assessment (PRA)) and to assess whether serum biomarkers can increase the prognostic accuracy of these RS. METHODS We prospectively assessed 610 consecutive UA/NSTEMI patients, 217 (36%) UA and 393 (64%) NSTEMI. In all patients RS, high sensitivity C-reactive protein, CD40 ligand, IL6, IL10, IL18, E-selectin, P-selectin, white blood cell count, neopterin, myeloperoxidase, fibrinogen and NT proBNP were assessed at study entry. The primary study endpoint was death and non-fatal MI at 30 and 360 days of follow-up. RESULTS At 1 year, 54 patients (8.9%) had reached the primary study endpoint (26 suffered a cardiac death (4.3%) and 34 (5.6%) a non-fatal MI). For both RS, the study endpoint occurred more commonly in patients at a "higher risk" compared to those classified as being at a "lower risk". Moreover, TIMI and PRA RS had similar discriminatory accuracy. TIMI RS, however, was a better predictor of events than PRA at both 30- and 360-day follow-up. The inflammatory biomarkers assessed in the study did not improve significantly the predictive value of RS. CONCLUSIONS Our study suggests both that TIMI RS is a better marker of risk than PRA RS and inflammatory biomarkers do not increase the predictive value of these clinical risk scores.

Abstract
Neopterin is produced by human and primate monocyte/macrophages upon activation by pro-inflammatory stimuli like Th1-type cytokine interferon-gamma. Neopterin has pro-oxidative properties, which have been demonstrated in vitro in physicochemical and cell culture studies and also in in vivo experiments, e.g. the Langendorff perfusion model of rat hearts. In the past several years, the measurement of neopterin concentrations in body fluids including serum, urine and cerebrospinal fluid has revealed a potential role of this molecule in the prediction of long-term prognosis in both patients with cancer and those with systemic infections such as HIV-1 infection. Moreover, elevated neopterin concentrations have been reported in patients with coronary disease compared to controls and in recent years it has become apparent that increased neopterin concentrations are an independent marker for cardiovascular disease and a predictor of future cardiovascular events in patients with coronary artery disease. Current data suggest that the diagnostic performance of neopterin testing is comparable to that of well established biomarkers such as C-reactive protein and cholesterol plasma levels. The present article reviews the role of neopterin in the pathogenesis of cardiovascular disease and as a marker of coronary artery disease progression.

Abstract
Increasing studies demonstrate a pivotal role for oxidant stress in the pathophysiology of heart failure (HF). Recent meta-analyses also reveal the potential pitfall of a mono-dimensional antioxidant approach. This review article summarizes the main biological pathways involved in oxidant stress and HF, the possible deleterious nature of certain antioxidant monotherapy and proposes potential antioxidant strategies necessary to challenge specific HF aetiology and progression.

Abstract
BACKGROUND A raised concentration of lipoprotein(a) [Lp(a)] in human plasma has been considered as a risk factor for coronary artery disease (CAD). Apolipoprotein(a) and plasminogen genes are exceptionally similar to a variable number of plasminogen-like kringle IV repeats in the apo(a) gene. Polymorphisms have been previously identified in the apolipoprotein(a) kringle IV 37. HYPOTHESIS In order to determine the frequency of the apolipoprotein(a) kringle IV 37 Met66-->Thr polymorphism in a London-based population and to assess the relationship of this polymorphism with CAD in Caucasian patients, we genotyped two groups of people of different ethnic origin (Caucasian and Afro-Caribbean) for the mutation using standard polymerase chain reaction (PCR) techniques. METHODS The first group consisted of 182 unrelated Caucasian patients (107 men and 75 women, mean age 59.7 +/- 10.2 years) recruited at St. George's Hospital. They were defined as patients with 0, 1 or > or = 2 vessel disease patients depending on the degree of stenosis in none, one, or several major epicardial arteries. The second group comprised 64 unrelated patients of Afro-Caribbean origin attending a hypertension clinic at St. George's Hospital. RESULTS It was shown that the prevalence of the Met66-->Thr mutation is markedly higher in Caucasians than in Afro-Caribbeans and that this mutation is not associated with either Lp(a) levels or severity of CAD.

Abstract
BACKGROUND Cardiac syndrome X is usually diagnosed in the presence of typical exertional chest pain, a positive response to exercise testing, and normal coronary angiograms. The underlying pathogenic mechanisms are speculative, but myocardial ischemia and increased sympathetic activity have been implicated. HYPOTHESIS The present study examined whether QTc interval is prolonged in women with syndrome X when confounding factors such as heart rate, gender, and environmental conditions are accounted for. METHODS Maximum QTc interval and its relationship to clinical and exercise variables were evaluated in 32 women with syndrome X (exertional chest pain, positive exercise testing, and completely normal coronary arteries) and 34 normal controls. RESULTS Patients with syndrome X had significantly longer QTc interval (440 +/- 24 ms) than normal subjects (410 +/- 26 ms, p < 0.004). However, this QTc prolongation appears to be heart rate-independent as patients with syndrome X showed longer QT and QTc intervals than controls despite an identical heart rate. No relation was found between QTc prolongation and clinical or exercise test variables in patients with syndrome X. CONCLUSION Although increased sympathetic drive is present in syndrome X, and this variable is likely to modulate QTc duration, the mechanism and clinical implications of QTc interval prolongation in syndrome X remain speculative.

Abstract
BACKGROUND Patients with chest pain and normal coronary arteriograms (CPNA) may present with unstable symptoms and other evidence of ischemia during clinical follow-up. Although repeat angiography usually proves negative, functional assessment of coronary vasomotor abnormalities may provide additional pathophysiologic information. HYPOTHESIS The study was undertaken to evaluate the relationship between endothelial dysfunction and subangiographic atheroma in patients with CPNA undergoing repeat angiography because of unstable symptoms. METHODS We investigated nine patients with CPNA (8 women, mean age 57 +/- 9 years) undergoing repeat angiography because of unstable anginal symptoms. After normal angiography, simultaneous coronary epicardial and microvascular vasomotor responses to intracoronary vasodilators [acetylcholine (10(-6) M), adenosine (18 micrograms) and nitroglycerin (300 micrograms)] were investigated in the left anterior descending artery using quantitative angiography and Doppler flow measurements. The presence of subangiographic atheroma was assessed by intravascular ultrasound. RESULTS Three patients demonstrated proximal and distal epicardial vasoconstriction and a reduction in coronary flow in response to acetylcholine, indicating concordant epicardial and microvascular endothelial dysfunction. These changes were associated with chest pain and ischemic electrocardiographic changes in two patients. None of the remaining patients suffered chest pain in response to intracoronary acetylcholine. Six patients had significant subangiographic disease (intimal thickness > 0.3 mm) on intravascular ultrasound imaging, and multivariate analysis indicated a significant relationship (R2 = 0.89, overall p = 0.001) between the extent of subangiographic disease and both plasma cholesterol concentration and hypertensive history. No significant relationship was demonstrated between endothelial dysfunction and the extent of subangiographic disease. CONCLUSION Concordant epicardial and microvascular endothelial dysfunction may be pathophysiologically and clinically significant in unstable patients with CPNA but does not appear to be directly related to the extent of subangiographic atheroma.

Abstract
BACKGROUND Plasma levels of soluble vascular cell adhesion molecule-1 (VCAM-1) and intercellular adhesion molecule-1 (ICAM-1) mediators of leukocyte adhesion to vascular endothelium may implicate in the pathogenesis of the syndrome of chest pain with normal coronary arteries. HYPOTHESIS We attempted to determine whether markers of endothelial activation are raised in patients with chest pain and normal coronary arteries. METHODS We measured plasma VCAM-1, ICAM-1 (ng/ ml) in 36 patients (34 men, 2 women, aged 62 +/- 9 years) with stable angina, coronary artery disease (CAD), and a positive response to exercise test; in 21 patients (6 men, 15 women, aged 56 +/- 9 years) with chest pain and normal coronary arteriograms (syndrome X); and in 11 healthy control subjects (8 men, 3 women, aged 49 +/- 14 years). RESULTS Plasma ICAM-1 levels were significantly higher both in patients with CAD (mean +/- standard error of the mean) (328 +/- 26, p < 0.05), and in syndrome X (362 +/- 22, p < 0.01) than in controls (225 +/- 29). VCAM-1 levels were also higher in syndrome X (656 +/- 42 ng/ml) and in patients with CAD (626 +/- 42 ng/ml) than in controls (551 +/- 60, p = 0.09). CONCLUSIONS ICAM-1 and VCAM-1 levels are increased both in patients with CAD and with syndrome X compared with control individuals. These findings may suggest the presence of chronic inflammation with involvement of the endothelium in patients with anginal chest pain and normal coronary angiograms.

Abstract
BACKGROUND AND HYPOTHESIS In patients with stable angina pectoris, eccentric stenoses have a greater potential for dynamic changes of caliber in response to vasoactive stimuli than concentric lesions. It is not known whether in patients with coronary artery spasm the degree of coronary vasoconstriction differs in eccentric versus concentric stenoses. Therefore, we examined the relationship between coronary stenosis morphology and the vasomotor response to vasoactive stimuli in patients with variant angina. METHODS Computerized quantitative angiography was used to measure minimum luminal diameter of eccentric and concentric stenoses before and after the administration of ergonovine and isosorbide dinitrate in 22 patients with Prinzmetal's variant angina and in 20 patients with chronic stable angina. RESULTS In patients with variant angina, mean stenosis diameter reduction with ergonovine was -0.85 +/- 0.38 and -1.12 +/- 0.69 mm in eccentric and concentric stenoses, respectively (p = NS). Isosorbide dinitrate promptly relieved spasm in all patients and increased the diameter of eccentric stenoses by 0.26 +/- 0.34 mm and that of concentric stenoses by 0.24 +/- 0.32 mm (p = NS). In patients with chronic stable angina, mean diameter reduction with ergonovine was -0.23 +/- 0.12 and -0.12 +/- 0.10 mm for eccentric and concentric stenoses, respectively (p < 0.05). Isosorbide dinitrate increased coronary diameter by 10% from baseline in 70% of eccentric and 38% of concentric stenoses (p < 0.01). CONCLUSION In patients with variant angina pectoris, eccentric and concentric spastic stenoses react similarly in response to vasoactive stimuli. In patients with chronic stable angina, eccentric stenoses are more likely to show vasomotor responses than concentric stenoses.

Abstract
This report from the first International Course on Integrated Biomarkers, Biochemical and Bioimaging Endpoints in Cardiovascular Diagnosis, Prevention, Therapy and Drug Development provides the basis for optimizing diagnostic, prognostic and therapeutic information in four areas of cardiovascular medicine: primary prevention of cardiovascular diseases, acute coronary syndromes, heart failure and stroke. Risk stratification and treatment strategies can be refined and enhanced through integration of bioimaging and biochemical markers to characterize sub-clinical and clinical atherosclerosis. For the integrative approach to be useful, each of the biomarkers must be validated and cost-effective. Clinical decision is the primary level of integration and is based on clinical evaluation and the use of a combination of bioimaging and biochemical markers. The decision to initiate preventive or therapeutic intervention must take into account the factors affecting the levels of expression of the biomarker and the potential input the biomarker has on metabolic processes or modulation of other biomarkers. The optimal approach to intervention must take into consideration the risk-benefit and cost-effectiveness ratios.

Abstract
CONDENSED ABSTRACT To investigate the predictive value of clinical data for infarction-related artery (IRA) occlusion and multivessel coronary disease in postinfarction angina (PIA), we studied 181 consecutive patients presenting PIA following a first uncomplicated ST elevation AMI. Multivariate analysis showed ECG changes during PIA and the absence of thrombolytic therapy as independent predictors of IRA occlusion. Independent clinical predictors of multivessel coronary disease were age, previous history of angina and the number of cardiovascular risk factors. We conclude that reversible ECG changes during PIA correlated to IRA occlusion but failed to predict a multivessel coronary disease. AIM To identify clinical variables predictive of infarction-related artery (IRA) occlusion and multivessel coronary disease in patients with postinfarction angina pectoris (PIA) after a first uncomplicated acute myocardial infarction (AMI). METHODS We studied 181 consecutive patients with PIA following a first uncomplicated AMI. Clinical variables included cardiovascular risk factors, clinical history of angina before the event of inclusion, use of thrombolytic therapy in the previous AMI, ST-T changes during PIA, time to onset, number of episodes and delay to angiography after PIA. Angiographic variables were IRA TIMI flow, number of diseased vessels and ventricular function. RESULTS The IRA was occluded in 67 patients with PIA (37.0%). Reversible ECG changes during PIA were detected in 121 patients (67.0%): 79 cases (43.6%) with ST/T elevation and 42 cases (23.2%) with ST/T depression. Multivariate logistic regression analysis showed ECG changes during PIA (OR 3.12 CI 95% 1.48-6.54, p<0.01) and the absence of thrombolytic therapy (OR 2.21 95% CI 1.11-4.43, p<0.05) as independent predictors of IRA occlusion. We found multivessel coronary disease in 89 patients (49.2%) without any correlation to ECG changes during PIA. Independent clinical predictors of multivessel coronary disease were age (OR 1.03 95% CI 1.01-1.06, p<0.05), previous history of angina (OR 2.37 95% CI 1.06-5.28, p<0.05) and the number of cardiovascular risk factors (OR 1.37 95% CI 0.97-1.92, p=0.07). CONCLUSIONS ECG changes during PIA was correlated to IRA occlusion in spite of previous thrombolytic therapy but failed to predict a multivessel coronary disease in our patients.

Abstract
The reported prevalence of Chlamydia pneumoniae in atherosclerotic tissue appears to depend on the detection system used. This introduces problems in determining the role of C. pneumoniae in atherosclerosis. This study analyses the sensitivity and performance of molecular diagnostic methods for the detection of C. pneumoniae and polymerase chain reaction (PCR) inhibitors in atheromatous tissue. Atherosclerotic tissue taken from 30 coronary endarterectomies, nine coronary arteries from explanted hearts, 16 carotid and two femoral endarterectomies are studied. Nested PCR (nPCR) assays targeting the PstI restriction fragment, the OmpA gene and the CRP operon of the chlamydial genome and immunocytochemistry (ICC) are used. Internal controls (IC) are constructed to co-amplify with the specific amplicons and identify the presence of inhibitor. The OmpA, PstI and CRP operon PCR assays had similar analytical sensitivities. However, the OmpA PCR was most affected by PCR inhibitors. Despite this, eight samples (14%) tested positive in the OmpA nPCR and no positives were found using the PstI or CRP operon nPCRs. Primary isolates of C. pneumoniae obtained from 12 patients with acute respiratory infection were positive in all three assays. Of the 48 specimens available for ICC, 33 (69%) were positive for chlamydial antigens. These included samples found positive by PCR. Dilution of samples to eliminate PCR inhibitors may have contributed to the discordant ICC and PCR results. The OmpA PCR, when used with an IC to identify samples with PCR inhibitors, is a reliable tool. However, the sensitivity of the ICC methods justifies their continued use.

Abstract
Cardiac syndrome X (CSX), defined as typical exertional chest pain, a positive response to stress testing, and normal coronary arteriograms, encompasses different pathogenic subgroups. Both cardiac and non-cardiac mechanisms have been suggested to play a pathogenic role, and it has been shown that the syndrome is associated with myocardial ischaemia in at least a proportion of patients. Radionuclide myocardial perfusion defects, coronary sinus oxygen saturation abnormalities and pH changes, myocardial lactate production and stress-induced alterations of cardiac high energy phosphate have been reported in CSX patients, suggesting an ischaemic origin for their symptoms. Microvascular abnormalities often caused by endothelial dysfunction appear to be responsible for myocardial ischaemia in these patients. CSX is more prevalent in women than in men, and the majority of women with CSX are peri- or post-menopausal. Thus oestrogen deficiency has been suggested to have a pathogenic role in CSX. Additional factors such as abnormal pain perception may also contribute to the genesis of chest pain in patients with angina and normal coronary angiograms. The management of this syndrome is difficult because of the heterogeneity of pathogenic mechanisms and uncertainties as to its origin. This article discusses the problem of CSX in women, the potential pathogenic role of oestrogen deficiency, and practical clinical management.

Abstract
In the last decade, compelling evidence has evolved at both the basic science and clinical level for the implication of inflammation in the pathogenesis of atherosclerosis and its complications. The composition of the atherosclerotic plaque, rather than the degree of stenosis, is now recognized as a pivotal feature in determining plaque vulnerability and hence the risk of acute coronary ischaemic events. Current evidence supports a key role for inflammation in all phases of the atherosclerotic process, from plaque formation through to progression and, ultimately, the thrombotic complications of atherosclerosis. The growing appreciation of the role of inflammation in atherogenesis has focused attention on whether circulating levels of inflammatory biomarkers may help to identify those at risk of future cardiovascular events. In addition, the protective effects of a variety of interventions, such as statins, aspirin, and fibrates, are often associated with the evidence of reduced inflammation, further strengthening the notion that inflammation and the acute complications of atherosclerosis are causally related. The present review describes the pathophysiology of atheromatous plaque vulnerability and discusses the clinical use of inflammatory biomarkers for prognostic stratification of patients with acute coronary syndromes.

Abstract
OBJECTIVE To investigate the association between Chlamydia pneumoniae and matrix metalloproteinase-9 (MMP-9) in atherosclerotic plaques. DESIGN 31 coronary atherosclerotic plaque specimens were studied by immunohistochemistry, polymerase chain reaction (PCR), and reverse transcription PCR for the presence of C pneumoniae antigen and genomic DNA, and of MMP-9 protein and transcripts. RESULTS Immunohistochemical analysis identified a strong association between the presence of C pneumoniae antigen and production of MMP-9 in coronary atherosclerotic plaques (p = 0.001). Furthermore, analysis of the intralesional amount of C pneumoniae and MMP-9 indicated an increased number of cells positive for MMP-9 in arterial sections that had increased C pneumoniae positivity (p < 0.05). CONCLUSIONS This study provides evidence of an association between expression of MMP-9 and the intravascular presence of C pneumoniae and may suggest a potential pathological mechanism whereby C pneumoniae may contribute to the progression of coronary atherosclerosis.

Abstract
BACKGROUND Diagnosis of cardiac ischaemia in patients attending emergency departments (ED) with symptoms of acute coronary syndromes is often difficult. Cardiac troponin (cTn) is sensitive and specific for the detection of myocardial damage but may not rise during reversible myocardial ischaemia. Ischemia Modified Albumin (IMA) has recently been shown to be a sensitive and early biochemical marker of ischaemia. METHODS AND RESULTS This study evaluated IMA in conjunction with ECG and cTn in 208 patients presenting to the ED within three hours of acute chest pain. At presentation, a 12-lead ECG was recorded and blood taken for IMA and cardiac troponin T (cTnT). Patients underwent standardised triage, diagnostic procedures, and treatment. Results of IMA, ECG, and cTnT, alone and in combination, were correlated with final diagnoses of non-ischaemic chest pain, unstable angina, ST segment elevation, and non-ST segment elevation myocardial infarction. In the whole patient group, sensitivity of IMA at presentation for an ischaemic origin of chest pain was 82%, compared with 45% of ECG and 20% of cTnT. IMA used together with cTnT or ECG, had a sensitivity of 90% and 92%, respectively. All three tests combined identified 95% of patients whose chest pain was attributable to ischaemic heart disease. In patients with unstable angina, sensitivity of IMA used alone was equivalent to that of IMA and ECG combined. CONCLUSIONS IMA is highly sensitive for the diagnosis of myocardial ischaemia in patients presenting with symptoms of acute chest pain.

Abstract
OBJECTIVE To assess the relation between markers of inflammation and the presence of multiple vulnerable plaques in patients with non-ST segment elevation acute coronary syndromes. DESIGN Prospective cohort study of 55 patients with non-ST segment elevation acute coronary syndromes and angiographically documented coronary disease. Blood samples were obtained at study entry for the assessment of high sensitivity C reactive protein (CRP), neopterin, and neutrophil count. Coronary stenoses were assessed by quantitative computerised angiography and classified as "complex" (irregular borders, ulceration, or filling defects) or "smooth" (absence of complex features). Extent of disease was also assessed by a validated angiographic score. RESULTS Neutrophil count (r = 0.36, p = 0.007), CRP concentration (r = 0.33, p = 0.02), and neopterin concentration (r = 0.45, p < 0.001) correlated with the number of complex stenoses. Patients with multiple (three or more) complex stenoses, but not patients with multiple smooth lesions, had a higher neutrophil count (5.9 (1.4) x 10(9)/l v 4.8 (1.4) x 10(9)/l, p = 0.02), CRP concentration (log transformed) (1.08 (0.63) v 0.6 (0.6), p = 0.03), and neopterin concentration (log transformed) (0.94 (0.18) v 0.79 (0.15), p = 0.002). Multiple regression analysis showed that neopterin concentration (B = 4.8, 95% confidence interval (CI) 1.9 to 7.7, p = 0.002) and extent of coronary artery disease (B = 0.6, 95% CI 0.03 to 1.2, p = 0.04) were independently associated with the number of complex stenoses. CONCLUSIONS Acute inflammatory markers such as high neutrophil count, CRP concentration, and neopterin concentration correlate with the presence of multiple angiographically complex coronary stenoses. Neopterin concentration was a stronger predictor of multiple complex plaques than were neutrophil count and CRP concentration. These findings suggest that a relation exists between inflammation and pancoronary plaque vulnerability.
