    Noncardioembolic stroke and coronary heart disease (CHD) may share genetic predispositions. We tested the hypothesis that genetic variants which are associated with risk of CHD would also be associated with risk of noncardioembolic stroke in 562 cases from the Vienna Stroke Registry and 815 controls. We selected 6 gene variants that had been consistently associated with risk of CHD in 3 studies, including the Atherosclerosis Risk in Communities study, and found that 4 of these gene variants were also associated with risk of noncardioembolic stroke. The odds ratios for noncardioembolic stroke were 1.31 (90% CI 1.07–1.60) for rs3900940 in MYH15, 1.24 (90% CI 1.01–1.5) for rs20455 in KIF6, 1.21 (90% CI 0.99–1.49) for rs1010 in VAMP8, and 1.20 (90% CI 0.95–1.50) for rs10757274 on chromosome 9p21.

    The coronary and extracranial carotid vascular beds are often simultaneously affected by significant atherosclerotic disease, and stroke is one of the potential major complications of coronary artery surgery. As a result, there is no shortage of reports in the vascular surgery literature describing simultaneous coronary and carotid artery revascularizations. Generally, these reports have found this combination of operations safe, but have stopped short of proving that it is necessary. Intuitively, simultaneous carotid endarterectomy and coronary artery bypass surgery could be justified if most perioperative strokes were the result of a significant carotid stenosis, either directly or indirectly. At first glance this appears to be a fairly straightforward issue; however, much of the evidence on both sides of the argument is circumstantial. One significant problem in analyzing outcome by choice of treatment in patients presenting with both coronary and carotid disease is the multiple potential causes of stroke in coronary bypass patients, which include hemorrhage and atheroemboli from aortic atheromas during clamping. But this controversial subject is now open to discussion, and our debaters have been given the challenge to clarify the evidence to justify their claims.

    Cardiovascular disease is the number one killer of women. Identifying women at risk of cardiovascular disease has tremendous public health importance. Early menopause is associated with increased cardiovascular disease events in some predominantly white populations, but not consistently. Our objective was to determine if self-reported early menopause (menopause at an age menopause (either natural menopause or surgical removal of ovaries at an age menopause. In survival curves, women with early menopause had worse coronary heart disease and stroke-free survival (log rank P = 0.008 and P = 0.0158). In models adjusted for age, race/ethnicity, Multi-ethnic Study Atherosclerosis site, and traditional cardiovascular disease risk factors, this risk for coronary heart disease and stroke remained (hazard ratio, 2.08; 95% CI, 1.17-3.70; and hazard ratio, 2.19; 95% CI, 1.11-4.32, respectively). Early menopause is positively associated with coronary heart disease and stroke in a multiethnic cohort, independent of traditional cardiovascular disease risk factors.

    Spousal caregivers of cancer patients suffer psychological and physical burdens that may affect their risk of subsequently developing coronary heart disease and stroke. Cancer patients were identified in the Swedish Cancer Registry, and information on their spouses was retrieved from the Swedish Multi-Generation Register. Follow-up of caregivers was performed from the date of the first diagnosis of cancer in their spouses through 2008. Standardized incidence ratios were calculated for spousal caregivers of cancer patients compared with those without an affected spouse. After the cancer diagnosis in wives, the risks of coronary heart disease, ischemic stroke, and hemorrhagic stroke in husbands were 1.13 (95% confidence interval [CI], 1.10-1.16), 1.24 (95% CI, 1.21-1.27), and 1.25 (95% CI, 1.18-1.32), respectively. The corresponding risks in wives with an affected husband were 1.13 (95% CI, 1.10-1.16), 1.29 (95% CI, 1.26-1.32), and 1.27 (95% CI, 1.19-1.34). The increases were consistent over time and were more pronounced if the spouse was affected by a cancer with a high mortality rate, such as pancreatic and lung cancers. Spousal caregivers of cancer patients have increased risks of coronary heart disease and stroke that persist over time. Clinical attention should be paid to spousal caregivers, especially those caring for cancer patients with high mortality rates.

    Randomized trials of antithrombotics in coronary artery disease have identified previous stroke/transient ischemic attack (TIA) as a marker of increased intracranial bleeding risk. We aimed to further characterize the risk of ischemic and bleeding events associated with a history of stroke/TIA in patients with coronary artery disease. From the international REduction of Atherothrombosis for Continued Health (REACH) registry of atherothrombosis, baseline characteristics and 4-year follow-up of 26,389 patients with coronary artery disease, including 4460 patients (16.9%) with a history of stroke/TIA, were analyzed. Patients with previous stroke/TIA had a higher rate of recurrent cardiovascular events (cardiovascular death, myocardial infarction, or stroke) than patients without (adjusted hazard ratio [HR], 1.52; 95% confidence interval [CI], 1.40-1.65; Phistory of stroke/TIA is associated with an independent increase in risk of death, myocardial infarction, or stroke, including both ischemic and hemorrhagic stroke (the latter being smaller in absolute terms). This excess risk of hemorrhagic stroke is particularly high in patients receiving dual antiplatelet therapy and in the 1st year after stroke/TIA. This observation is important for selection of antithrombotic therapy in these patients.

    2012-01-01

    Background Low intellectual ability is associated with an increased risk of coronary heart disease and stroke. Most studies have used a general intelligence score. We studied whether three different subscores of intellectual ability predict these disorders. Methods We studied 2,786 men, born between 1934 and 1944 in Helsinki, Finland, who as conscripts at age 20 underwent an intellectual ability test comprising verbal, visuospatial (analogous to Raven's progressive matrices) and arithmetic reasoning subtests. We ascertained the later occurrence of coronary heart disease and stroke from validated national hospital discharge and death registers. Results 281 men (10.1%) had experienced a coronary heart disease event and 131 (4.7%) a stroke event. Coronary heart disease was predicted by low scores in all subtests, hazard ratios for each standard deviation (SD) lower score ranging from 1.21 to 1.30 (confidence intervals 1.08 to 1.46). Stroke was predicted by a low visuospatial reasoning score, the corresponding hazard ratio being 1.23 (95% confidence interval 1.04 to 1.46), adjusted for year and age at testing. Adjusted in addition for the two other scores, the hazard ratio was 1.40 (1.10 to 1.79). This hazard ratio was little affected by adjustment for socioeconomic status in childhood and adult life, whereas the same adjustments attenuated the associations between intellectual ability and coronary heart disease. The associations with stroke were also unchanged when adjusted for systolic blood pressure at 20 years and reimbursement for adult antihypertensive medication. Conclusions Stroke is predicted by low visuospatial reasoning scores in relation to scores in the two other subtests. This association may be mediated by common underlying causes such as impaired brain development, rather than by mechanisms associated with risk factors shared by stroke and coronary heart disease, such as socio-economic status, hypertension and atherosclerosis.

    Full Text Available BACKGROUND: Evidence suggests that variations in fasting glucose and insulin amongst those without frank type 2 diabetes mellitus are important determinants of cardiovascular disease. However, the relative importance of variations in fasting insulin, glucose, and glycated haemoglobin as risk factors for cardiovascular disease in women without diabetes is unclear. Our aim was to determine the independent associations of fasting insulin, glucose, and glycated haemoglobin with coronary heart disease and stroke in older women. METHODS AND FINDINGS: We undertook a prospective cohort study of 3,246 British women aged 60-79 y, all of whom were free of baseline coronary heart disease, stroke, and diabetes, and all of whom had fasting glucose levels below 7 mmol/l. Fasting insulin and homeostasis model assessment for insulin sensitivity (HOMA-S were linearly associated with a combined outcome of coronary heart disease or stroke (n = 219 events, but there was no association of fasting glucose or glycated haemoglobin with these outcomes. Results were similar for coronary heart disease and stroke as separate outcomes. The age, life-course socioeconomic position, smoking, and physical activity adjusted hazard ratio for a combined outcome of incident coronary heart disease or stroke per one standard deviation of fasting insulin was 1.14 (95% CI 1.02-1.33. Additional adjustment for other components of metabolic syndrome, low-density lipoprotein cholesterol, fasting glucose, and glycated haemoglobin had little effect on this result. CONCLUSIONS: Our findings suggest that in women in the 60-79 y age range, insulin resistance, rather than insulin secretion or chronic hyperglycaemia, is a more important risk factor for coronary heart disease and stroke. Below currently used thresholds of fasting glucose for defining diabetes, neither fasting glucose nor glycated haemoglobin are associated with cardiovascular disease.

    Background: Resting heart rate is linked to risk of coronary artery disease, stroke, sudden death and noncardiovascular diseases. We conducted a meta-analysis to assess these associations in general populations and in populations of patients with hypertension or diabetes mellitus. Methods: We searched PubMed, Embase and MEDLINE from inception to Mar. 5, 2016. We used a random-effects model to combine study-specific relative risks (RRs). We used restricted cubic splines to assess the dose–response relation. Results: We included 45 nonrandomized prospective cohort studies in the meta-analysis. The multivariable adjusted RR with an increment of 10 beats/min in resting heart rate was 1.12 (95% confidence interval [CI] 1.09–1.14) for coronary artery disease, 1.05 (95% CI 1.01–1.08) for stroke, 1.12 (95% CI 1.02–1.24) for sudden death, 1.16 (95% CI 1.12–1.21) for noncardiovascular diseases, 1.09 (95% CI 1.06–1.12) for all types of cancer and 1.25 (95% CI 1.17–1.34) for noncardiovascular diseases excluding cancer. All of these relations were linear. In an analysis by category of resting heart rate ( 80 beats/min), the RRs were 0.99 (95% CI 0.93–1.04), 1.08 (95% CI 1.01–1.16) and 1.30 (95% CI 1.19–1.43), respectively, for coronary artery disease; 1.08 (95% CI 0.98–1.19), 1.11 (95% CI 0.98–1.25) and 1.08 (95% CI 0.93–1.25), respectively, for stroke; and 1.17 (95% CI 0.94–1.46), 1.31 (95% CI 1.12–1.54) and 1.57 (95% CI 1.39–1.77), respectively, for noncardiovascular diseases. After excluding studies involving patients with hypertension or diabetes, we obtained similar results for coronary artery disease, stroke and noncardiovascular diseases, but found no association with sudden death. Interpretation: Resting heart rate was an independent predictor of coronary artery disease, stroke, sudden death and noncardiovascular diseases over all of the studies combined. When the analysis included only studies concerning general populations, resting

    Full Text Available Stroke is a major cause of mortality and morbidity worldwide and commonly occurs amongst elderly. Every year, 15 million people worldwide suffer from stroke. Hypertension is the most powerful and important modifiable risk factor for all stroke subtypes. Approximately 30-40% stroke risk reduction can be achieved with lowering of blood pressure only. Heart disease is also a strong risk factor for stroke, although only for one type of stroke, ischemic strokes. MATERIALS AND METHODS This was a retrospective, cross-sectional, case-control study conducted from Jan-2015 to March-2015 (3 months. Study was done among stroke patients aged 20 years and above, hospitalized in M.G.M Medical College and L.S.K Hospital, Kishanganj. Age and gender matched control subjects were selected among neurologically healthy people who were admitted for other ailments in this hospital. Sample size was 312 people, containing 156 cases and 156 controls. Statistical analysis was done using Med Calc Version 12.7.5.0 software. Chi-square test was used as test of significance and p value less than 0.05 was considered as significant. OBSERVATION Male:Female ratio among the cases and control was 1.51:1. Mean age of cases and controls were 51.30±11.13 and 51.93±14.60. Out of 156 cases, 97 (62.18 % cases were having history of hypertension, while only 33 (21.15% controls had hypertension. P value was 0.0001, which is significant. Coronary heart disease was present in 21 (13.46% of cases and 6 (3.85% of controls. P value was significant. CONCLUSION To conclude in the present hospital-based case control study, systemic hypertension (p<0.001 and coronary heart diseases were significant risk factors in patients with stroke. Thus, our present study is a step towards determination of risk factors of stroke.

    2017-08-01

    We aimed to quantitatively assess the potential relationship between kidney stones and coronary heart disease or stroke. A meta-analysis was conducted on eligibly studies published before 31 May 2016 in PubMed or Embase. The data were pooled, and the relationship was assessed by the random-effect model with inverse variance-weighted procedure. The results were expressed as relative risk (RR) with 95% confidence intervals (95%CI). Eight studies of 11 cohorts (n = 11) were included in our analysis with 3,658,360 participants and 157,037 cases. We found that a history of kidney stones was associated with increased risk of coronary heart disease (CHD) (RR = 1.24; 95%CI: 1.14-1.36; I = 79.0%, n = 11); similar effect on myocardial infarction, a serious condition of CHD, was observed (RR = 1.24; 95%CI: 1.10-1.40; I = 80.4%, n = 8). We also found that a history of kidney stones may increase the risk of stroke (RR = 1.21, 95%CI: 1.06-1.38; I = 54.7%, n = 4). In subgroup analysis, the risk of coronary heart disease was higher in men (RR = 1.23, 95%CI: 1.02-1.49) while the risk for stroke was higher in women (RR = 1.12; 95%CI: 1.03-1.21). No obvious publications bias was detected (Egger test: P = .47). Kidney stones are associated with increased risk of coronary heart disease and stroke, and the effect may differ by sex.

    Psychosocial stress has been widely studied as a risk factor for stroke and coronary heart disease (CHD) but little is known about the differential effects of stress on stroke and CHD risk by race and sex. Caregiving for a disabled spouse has been associated with increased mortality and CHD risk, but the association of caregiving strain with stroke and CHD risk across race and sex is unknown. Participants in the REasons for Geographic and Racial Differences in Stroke (REGARDS) study who were providing in-home caregiving to a disabled spouse reported on caregiving strain (high, some, or none), depressive symptoms, social network, education, and age. Caregiving strain groups were compared on the Framingham Stroke Risk Score (N=716) and Framingham CHD Risk Score (N=607), which estimate the projected 10-year risk of incident stroke and ischemic heart disease, respectively. High caregiving strain was associated with a 23% higher covariate-adjusted estimated stroke risk (11.06% for caregivers with no strain versus 13.62% risk for high-strain caregivers). This association was stronger in men, particularly African American men with high caregiving strain (26.95% estimated 10-year stroke risk). Caregiving strain was not associated with CHD risk scores. Caregiving strain is significantly associated with higher estimated stroke risk with greatest effects for men, particularly African American men, providing caregiving to their wives. Male spouse caregivers may need special caregiving support. Prospective longitudinal studies should examine how sex and race may moderate the impact of stress on stroke and CHD risk.

    Background Stroke is a rare but serious adverse event associated with percutaneous coronary intervention (PCI). However, the relative risk of stroke between stable patients undergoing a direct PCI strategy and those undergoing an initial optimal medical therapy (OMT) strategy has not been established yet. This study sought to investigate if, in patients with stable coronary artery disease (SCAD), an initial strategy PCI is associated with a higher risk of stroke than a strategy based on OMT alone. Methods We performed a meta-analysis of 6 contemporary randomized control trials in which 5673 patients with SCAD were randomized to initial PCI or OMT. Only trials with stent utilization more than 50% were included. Study endpoint was the rate of stroke during follow up. Results Mean age of patients ranged from 60 to 65 years and stent utilization ranged from 72% to 100%. Rate of stroke was 2.0% at a weighted mean follow up of 55.3 months. On pooled analysis, the risk of stroke was similar between patients undergoing a PCI plus OMT and those receiving only OMT (2.2% vs. 1.8%, OR on fixed effect = 1.24 95%CI: 0.85–1.79). There was no heterogeneity among the studies (I2 = 0.0%, P = 0.15). On sensitivity analysis after removing each individual study the pooled effect estimate remains unchanged. Conclusions In patients with SCAD an initial strategy based on a direct PCI is not associated with an increased risk of stroke during long-term follow up compared to an initial strategy based on OMT alone.

    Aims Although dietary saturated fatty acids (SFA) are considered atherogenic, associations between SFAs intake and stroke and coronary heart disease are still debated. We sought to test the hypothesis that SFA intake is associated inversely with risk of stroke and its subtypes and positively with coronary heart disease among Japanese, whose average SFA intake is lower than that of Westerners. Methods and results The Japan Public Health Center-based prospective Study involves two subcohorts: Cohort I, aged 45-64 in 1995 and followed-up through 2009, and Cohort II, aged 45-74 in 1998 and followed-up through 2007. A total of 38 084 men and 43 847 women were included in this report. Hazards ratios for incident total stroke, ischaemic stroke, intraparhenchymal haemorrhage, subarachnoid haemorrhage, myocardial infarction, and sudden cardiac death across quintiles of dietary SFAs were examined. We found inverse associations between SFA intake and total stroke [multivariable hazard ratio (95% confidence interval) for the highest vs. lowest quintiles = 0.77 (0.65-0.93), trend P = 0.002], intraparenchymal haemorrhage [0.61 (0.43-0.86), P for trend = 0.005], and ischaemic stroke [0.84 (0.67-1.06), trend P = 0.08], primarily for deep intraparenchymal haemorrhage [0.67 (0.45-0.99), P for trend = 0.04] and lacunar infarction [0.75 (0.53, 1.07), trend P = 0.02]. We also observed a positive association between SFAs intake and myocardial infarction [1.39 (0.93-2.08), trend P = 0.046] primarily among men. No associations were observed between SFAs intake and incidence of subarachnoid haemorrhage or sudden cardiac death. Conclusions In this Japanese population, SFAs intake was inversely associated with deep intraparenchymal haemorrhage and lacunar infarction and positively associated with myocardial infarction.

  17. Comparing the decline in coronary heart disease and stroke mortality in neighbouring countries with different healthcare systems.

    OBJECTIVE: To examine age and gender specific trends in coronary heart disease (CHD) and stroke mortality in two neighbouring countries, the Republic of Ireland (ROI) and Northern Ireland (NI). DESIGN: Epidemiological study of time trends in CHD and stroke mortality. SETTING\\/PATIENTS: The populations of the ROI and NI, 1985-2010. INTERVENTIONS: None. MAIN OUTCOME MEASURES: Directly age standardised CHD and stroke mortality rates were calculated and analysed using joinpoint regression to identify years where the slope of the linear trend changed significantly. This was performed separately for specific age groups (25-54, 55-64, 65-74 and 75-84 years) and by gender. Annual percentage change (APC) and 95% CIs are presented. RESULTS: There was a striking similarity between the two countries, with percentage change between 1985 and 1989 and between 2006 and 2010 of 67% and 69% in CHD mortality, and 64% and 62% in stroke mortality for the ROI and NI, respectively. However, joinpoint analysis identified differences in the pace of change between the two countries. There was an accelerated pace of decline (negative APC) in mortality for both CHD and stroke in both countries from the mid-1990s (APC ROI -8% (95% CI -9.5 to 6.5) and NI -6.6% (-6.9 to -6.3)), but the accelerated decrease started later for CHD mortality in the ROI. In recent years, a levelling off in CHD mortality was observed in the 25-54 year age group in NI and in stroke mortality for men and women in the ROI. CONCLUSIONS: While differences in the pace of change in mortality were observed at different time points, similar, substantial decreases in CHD and stroke mortality were achieved between 1985 and 1989 and between 2006 and 2010 in the ROI and NI despite important differences in health service structures. There is evidence of a levelling in mortality rates in some groups in recent years.

    The vascular smooth muscle cell (SMC)-specific isoform of α-actin (ACTA2) is a major component of the contractile apparatus in SMCs located throughout the arterial system. Heterozygous ACTA2 mutations cause familial thoracic aortic aneurysms and dissections (TAAD), but only half of mutation carriers have aortic disease. Linkage analysis and association studies of individuals in 20 families with ACTA2 mutations indicate that mutation carriers can have a diversity of vascular diseases, including premature onset of coronary artery disease (CAD) and premature ischemic strokes (including Moyamoya disease [MMD]), as well as previously defined TAAD. Sequencing of DNA from patients with nonfamilial TAAD and from premature-onset CAD patients independently identified ACTA2 mutations in these patients and premature onset strokes in family members with ACTA2 mutations. Vascular pathology and analysis of explanted SMCs and myofibroblasts from patients harboring ACTA2 suggested that increased proliferation of SMCs contributed to occlusive diseases. These results indicate that heterozygous ACTA2 mutations predispose patients to a variety of diffuse and diverse vascular diseases, including TAAD, premature CAD, ischemic strokes, and MMD. These data demonstrate that diffuse vascular diseases resulting from either occluded or enlarged arteries can be caused by mutations in a single gene and have direct implications for clinical management and research on familial vascular diseases.

Novel antiplatelet agents have been established for the management of patients with clinically evident coronary atherothrombosis and are increasingly used in these patients. These agents, however, have shown limited efficacy in the prevention of cerebrovascular events and potential harm in patients with history of stroke or transient ischemic attack. Herein, the efficacy and safety of two established antiplatelet agents in patients with stroke – aspirin and clopidogrel – are reviewed with a focus on the use and challenges related to novel antiplatelet agents – prasugrel, ticagrelor, and vorapaxar – in patients at risk for and with a history of stroke or transient ischemic attack.

    Although epidemiological studies have examined the role of chocolate in preventing cardiometabolic disease, the results remain inconsistent. Herein, we conducted a meta-analysis of prospective studies to determine the association between chocolate intake and risk of coronary heart disease (CHD), stroke, and diabetes. A systematical search in PubMed and Embase through March 2017, together with reference scrutiny of relevant literatures, was performed to identify eligible studies. Relative risks (RRs) and 95% confidence intervals (CIs) were pooled using random effect models. Fourteen prospective studies of primary prevention with 508,705 participants were finally included, with follow-up durations ranging from 5 to 16 years. The summary RRs for the highest versus lowest chocolate consumption were 0.90 (95% CI: 0.82-0.97; n = 6) for CHD, 0.84 (95% CI: 0.78-0.90; n = 7) for stroke, and 0.82 (95% CI: 0.70-0.96; n = 5) for diabetes. Dose-response meta-analysis suggested a nonlinear association of chocolate consumption with all outcomes. For both CHD and stroke, there was little additional risk reduction when consuming chocolate ≥3 servings/week (one serving was defined as 30 g of chocolate). For diabetes, the peak protective effect of chocolate emerged at 2 servings/week (RR: 0.75, 95% CI: 0.63-0.89), with no benefit observed when increasing consumption above 6 servings/week. In conclusion, chocolate intake is associated with decreased risks of CHD, stroke, and diabetes. Consuming chocolate in moderation (≤6 servings/week) may be optimal for preventing these disorders.

  3. Effect of alcohol on risk of coronary heart disease and stroke: causality, bias, or a bit of both?

    Full Text Available Jonathan R Emberson, Derrick A BennettClinical Trial Service Unit, Richard Doll Building, University of Oxford, Oxford, UKAbstract: Epidemiological studies of middle-aged populations generally find the relationship between alcohol intake and the risk of coronary heart disease (CHD and stroke to be either U- or J-shaped. This review describes the extent that these relationships are likely to be causal, and the extent that they may be due to specific methodological weaknesses in epidemiological studies. The consistency in the vascular benefit associated with moderate drinking (compared with non-drinking observed across different studies, together with the existence of credible biological pathways, strongly suggests that at least some of this benefit is real. However, because of biases introduced by: choice of reference categories; reverse causality bias; variations in alcohol intake over time; and confounding, some of it is likely to be an artefact. For heavy drinking, different study biases have the potential to act in opposing directions, and as such, the true effects of heavy drinking on vascular risk are uncertain. However, because of the known harmful effects of heavy drinking on non-vascular mortality, the problem is an academic one. Studies of the effects of alcohol consumption on health outcomes should recognise the methodological biases they are likely to face, and design, analyse and interpret their studies accordingly. While regular moderate alcohol consumption during middle-age probably does reduce vascular risk, care should be taken when making general recommendations about safe levels of alcohol intake. In particular, it is likely that any promotion of alcohol for health reasons would do substantially more harm than good. Keywords: alcohol, coronary heart disease, stroke

    Full Text Available Background: The associations of bowel movement frequency and laxative use with cardiovascular disease (CVD are unclear. Methods: A total of 72 014 subjects (29 668 men and 42 346 women aged 40 to 79 years, without a history of CVD or cancer, completed a lifestyle questionnaire at baseline between 1988 and 1990 that included information on bowel movement frequency (daily, every 2–3 days, or once every 4 or more days and laxative use (yes or no, and were followed-up until 2009. Results: During the subjects’ 1 165 569 person-years of follow-up, we documented 977 deaths from coronary heart disease (561 men and 416 women, 2024 from total stroke (1028 men and 996 women, 1127 from ischemic stroke (606 men and 521 women, and 828 from hemorrhagic stroke (388 men and 440 women. The prevalence of CVD risk factors, such as diabetes, stress, depression, and physical inactivity, was higher in laxative users and in those with a lower frequency of bowel movements. The multivariable HRs (95% confidence intervals [CIs] of laxative users were as follows: 1.56 (95% CI, 1.21–2.03 for coronary heart disease and 1.37 (95% CI, 1.07–1.76 for ischemic stroke in men, and 1.27 (95% CI, 1.08–1.49 for total stroke, and 1.45 (95% CI, 1.17–1.79 for ischemic stroke in women. Similar results were observed even after the exclusion of deaths that occurred early in the follow-up period. A significant association between bowel movement frequency and mortality from CVD was not observed. Conclusions: Constipation could be a marker of exposure to CVD risk factors, and laxative use could be a risk factor for mortality from coronary heart disease and ischemic stroke.

    Dietary and policy recommendations frequently focus on reducing saturated fatty acid consumption for improving cardiometabolic health, based largely on ecologic and animal studies. Recent advances in nutritional science now allow assessment of critical questions about health effects of saturated fatty acids (SFA). We reviewed the evidence from randomized controlled trials (RCTs) of lipid and non-lipid risk factors, prospective cohort studies of disease endpoints, and RCTs of disease endpoints for cardiometabolic effects of SFA consumption in humans, including whether effects vary depending on specific SFA chain-length; on the replacement nutrient; or on disease outcomes evaluated. Compared with carbohydrate, the TC:HDL-C ratio is nonsignificantly affected by consumption of myristic or palmitic acid, is nonsignificantly decreased by stearic acid, and is significantly decreased by lauric acid. However, insufficient evidence exists for different chain-length-specific effects on other risk pathways or, more importantly, disease endpoints. Based on consistent evidence from human studies, replacing SFA with polyunsaturated fat modestly lowers coronary heart disease risk, with ~10% risk reduction for a 5% energy substitution; whereas replacing SFA with carbohydrate has no benefit and replacing SFA with monounsaturated fat has uncertain effects. Evidence for the effects of SFA consumption on vascular function, insulin resistance, diabetes, and stroke is mixed, with many studies showing no clear effects, highlighting a need for further investigation of these endpoints. Public health emphasis on reducing SFA consumption without considering the replacement nutrient or, more importantly, the many other food-based risk factors for cardiometabolic disease is unlikely to produce substantial intended benefits.

    The authors aimed to quantify the effects of current systolic blood pressure (SBP) and serum total cholesterol on the risk of mortality in comparison with SBP or serum cholesterol 25 years previously, taking measurement error into account. The authors reanalyzed 35-year follow-up data on mortality due to coronary heart disease and stroke among subjects aged 65 years or more from nine cohorts of the Seven Countries Study. The two-step method of Tsiatis et al. (J Am Stat Assoc 1995;90:27-37) was used to adjust for regression dilution bias, and results were compared with those obtained using more commonly applied methods of adjustment for regression dilution bias. It was found that the commonly used univariate adjustment for regression dilution bias overestimates the effects of both SBP and cholesterol compared with multivariate methods. Also, the two-step method makes better use of the information available, resulting in smaller confidence intervals. Results comparing recent and past exposure indicated that past SBP is more important than recent SBP in terms of its effect on coronary heart disease mortality, while both recent and past values seem to be important for effects of cholesterol on coronary heart disease mortality and effects of SBP on stroke mortality. Associations between serum cholesterol concentration and risk of stroke mortality are weak.

    Full Text Available The present study was performed to clarify the association between the acyl-CoA:cholesterol acyltransferase-1 (ACAT-1 single nucleotide polymorphism (SNP rs1044925 and the risk of coronary artery disease (CAD and ischemic stroke (IS in the Guangxi Han population. Polymerase chain reaction and restriction fragment length polymorphism was performed to determine the genotypes of the ACAT-1 SNP rs1044925 in 1730 unrelated subjects (CAD, 587; IS, 555; and healthy controls; 588. The genotypic and allelic frequencies of rs1044925 were significantly different between the CAD patients and controls (p = 0.015 and borderline different between the IS patients and controls (p = 0.05. The AC/CC genotypes and C allele were associated with a decreased risk of CAD and IS (CAD: p = 0.014 for AC/CC vs. AA, p = 0.022 for C vs. A; IS: p = 0.014 for AC/CC vs. AA; p = 0.017 for C vs. A. The AC/CC genotypes in the healthy controls, but not in CAD or IS patients, were associated with an increased serum high-density lipoprotein cholesterol (HDL-C concentration. The present study shows that the C allele carriers of ACAT-1 rs1044925 were associated with an increased serum HDL-C level in the healthy controls and decreased risk in CAD and IS patients.

    The Quality and Outcomes Framework (QOF), a major pay-for-performance programme, was introduced into United Kingdom primary care in April 2004. The impact of this programme on disparities in health care remains unclear. This study examines the following questions: has this pay for performance programme improved the quality of care for coronary heart disease, stroke and hypertension in white, black and south Asian patients? Has this programme reduced disparities in the quality of care between these ethnic groups? Did general practices with different baseline performance respond differently to this programme? Retrospective cohort study of patients registered with family practices in Wandsworth, London during 2007. Segmented regression analysis of interrupted time series was used to take into account the previous time trend. Primary outcome measures were mean systolic and diastolic blood pressure, and cholesterol levels. Our findings suggest that the implementation of QOF resulted in significant short term improvements in blood pressure control. The magnitude of benefit varied between ethnic groups with a statistically significant short term reduction in systolic BP in white and black but not in south Asian patients with hypertension. Disparities in risk factor control were attenuated only on few measures and largely remained intact at the end of the study period. Pay for performance programmes such as the QOF in the UK should set challenging but achievable targets. Specific targets aimed at reducing ethnic disparities in health care may also be needed.

    Full Text Available Coronary heart disease (CHD and stroke are common complications of type 2 diabetes mellitus (T2DM. We aimed to explore the differences in the risks of CHD and stroke between Chinese women and men with T2DM and their association with metabolic syndrome (MS. This study included 1514 patients with T2DM. The Asian Guidelines of ATPIII (2005 were used for MS diagnosis, and the UKPDS risk engine was used to evaluate the 10-year CHD and stroke risks. Women had lower CHD risk (15.3% versus 26.3%, fatal CHD risk (11.8% versus 19.0%, stroke risk (8.4% versus 10.3%, and fatal stroke risk (1.4% versus 1.6% compared with men with T2DM (p<0.05–0.001. The CHD risk (28.4% versus 22.6%, p<0.001 was significantly higher in men with MS than in those without MS. The CHD (16.2% versus 11.0%, p<0.001 and stroke risks (8.9% versus 5.8%, p<0.001 were higher in women with MS than in those without MS. In conclusion, our findings indicated that Chinese women with T2DM are less susceptible to CHD and stroke than men. Further, MS increases the risk of both these events, highlighting the need for comprehensive metabolic control in T2DM.

    Full Text Available Persistent non-valvular atrial fibrillation (NVAF is associated with an increased risk of cardiovascular events such as stroke, and its rate is expected to rise because of the ageing population. The absolute rate of stroke depends on age and comorbidity. Risk stratification for stroke in patients with NVAF derives from populations enrolled in randomized clinical trials. However, participants in clinical trials are often not representative of the general population. Many stroke risk stratification scores have been used, but they do not include transthoracic echocardiogram (TTE, pulsate wave Doppler (PWD and tissue Doppler imaging (TDI, simple and non-invasive diagnostic tools. The role of TTE, PWD and TDI findings has not been previously determined. Our study goal was to determine the association between TTE and PWD findings and stroke prevalence in a population of NVAF prone outpatients. Patients were divided into two groups: P for stroke prone and F for stroke free. There were no statistically significant differences between the two groups concerning cardiovascular risk factors, age (p=0.2, sex (p=0.2, smoking (p=0.3, diabetes (p=0.1 and hypercholesterolemia (p=0.2; hypertension was statistically significant (p less than 0.001. There were statistically significant differences concerning coronary artery disease, previous acute myocardial infarction (AMI (p less than 0.05 and non- AMI coronaropathy (p less than 0.04, a higher rate being in the P group.

    The implications of different adiposity measures on cardiovascular disease etiology remain unclear. In this article, we quantify and contrast causal associations of central adiposity (waist-to-hip ratio adjusted for body mass index [WHRadjBMI]) and general adiposity (body mass index [BMI]) with cardiometabolic disease. Ninety-seven independent single-nucleotide polymorphisms for BMI and 49 single-nucleotide polymorphisms for WHRadjBMI were used to conduct Mendelian randomization analyses in 14 prospective studies supplemented with coronary heart disease (CHD) data from CARDIoGRAMplusC4D (Coronary Artery Disease Genome-wide Replication and Meta-analysis [CARDIoGRAM] plus The Coronary Artery Disease [C4D] Genetics; combined total 66 842 cases), stroke from METASTROKE (12 389 ischemic stroke cases), type 2 diabetes mellitus from DIAGRAM (Diabetes Genetics Replication and Meta-analysis; 34 840 cases), and lipids from GLGC (Global Lipids Genetic Consortium; 213 500 participants) consortia. Primary outcomes were CHD, type 2 diabetes mellitus, and major stroke subtypes; secondary analyses included 18 cardiometabolic traits. Each one standard deviation (SD) higher WHRadjBMI (1 SD≈0.08 U) associated with a 48% excess risk of CHD (odds ratio [OR] for CHD, 1.48; 95% confidence interval [CI], 1.28-1.71), similar to findings for BMI (1 SD≈4.6 kg/m(2); OR for CHD, 1.36; 95% CI, 1.22-1.52). Only WHRadjBMI increased risk of ischemic stroke (OR, 1.32; 95% CI, 1.03-1.70). For type 2 diabetes mellitus, both measures had large effects: OR, 1.82 (95% CI, 1.38-2.42) and OR, 1.98 (95% CI, 1.41-2.78) per 1 SD higher WHRadjBMI and BMI, respectively. Both WHRadjBMI and BMI were associated with higher left ventricular hypertrophy, glycemic traits, interleukin 6, and circulating lipids. WHRadjBMI was also associated with higher carotid intima-media thickness (39%; 95% CI, 9%-77% per 1 SD). Both general and central adiposity have causal effects on CHD and type 2 diabetes mellitus

    The fluidity of dietary fatty acids consumed has been suggested to inversely affect coronary heart disease (CHD) risk. Lipophilic index (LI) represents overall fluidity of the dietary fatty acid profile. Lipophilic load (LL) represents a combination of overall fluidity and absolute intake of dietary fatty acids. We investigated the relations of dietary LI and LL with risk of CHD and ischemic stroke (iStroke). We used data from the prospective EPIC-NL study, including 36,520 participants aged 20-70 years. LI and LL were calculated using dietary intake data estimated with a validated FFQ. Incident CHD (n = 2348) and iStroke (n = 479) cases were obtained through linkage to national registers during 15 years follow-up. LI and LL were not associated with CHD risk (HRshighest-versus-lowest-quartiles: 0.93 [95%CI: 0.83, 1.04], and 0.92 [95%CI: 0.79, 1.07], respectively), and neither with iStroke risk (HRs 1.15 (95%CI: 0.89, 1.48), and 0.98 (95%CI: 0.70, 1.38), respectively). Original fatty acid classes (SFA, MUFA and PUFA), and LI and LL stratified by these fatty acid classes, were overall not related to CHD and ischemic stroke either. In this Dutch population, neither the overall fluidity of the dietary fatty acid profile (LI), nor the combined fluidity and amount of fatty acids consumed (LL) were related to CHD or iStroke risk. Dietary LI and LL may have limited added value above original fatty acid classes and food sources in establishing the relation of fatty acid consumption with CVD.

    Blood pressure (BP) and low-density lipoprotein cholesterol (LDL-C) are risk factors for coronary artery disease (CAD) and ischemic stroke. However, the hazards of their coexistence are not fully understood in Asian populations. We investigated whether the relationship between BP and cardiovascular disease (CVD) outcomes are modified by LDL-C level in a Japanese population. Individuals aged 30-79 years (n = 5,151) were classified into 6 groups according to LDL-C levels (low LDL-C and optimal BP). Hazard ratios (HRs) were calculated after adjusting for age, high-density lipoprotein cholesterol, diabetes, smoking status, and alcohol consumption. The effect modification of LDL-C on BP-CVD association was assessed using likelihood ratio tests. There were 264 CAD and 215 ischemic stroke events during 13 years of follow-up. With low LDL-C, the HRs of prehypertension and hypertension for CAD were 2.01 and 4.71, respectively. Similar trends of HRs were observed with high LDL-C (optimal BP = 2.09, prehypertension = 3.45, hypertension = 5.94). However, the HRs for ischemic stroke did not differ between normal and high LDL-C levels at the same BP level. The apparent effect modification of LDL-C was not observed in the BP-CVD association in either CAD (P = 0.48) or ischemic stroke (P = 0.39). The HRs for CAD in prehypertensive and hypertensive groups were higher than those in the optimal BP group at the same LDL-C levels in a Japanese population; however, there was no statistical effect modification of LDL-C on the BP-CAD association. © American Journal of Hypertension, Ltd 2014.

    Koert N J Burger

    Full Text Available BACKGROUND: The associations of glycemic load (GL and glycemic index (GI with the risk of cardiovascular diseases (CVD are not well-established, particularly in men, and may be modified by gender. OBJECTIVE: To assess whether high dietary GL and GI increase the risk of CVD in men and women. METHODS: A large prospective cohort study (EPIC-MORGEN was conducted within the general Dutch population among 8,855 men and 10,753 women, aged 21-64 years at baseline (1993-1997 and free of diabetes and CVD. Dietary intake was assessed with a validated food-frequency questionnaire and GI and GL were calculated using Foster-Powell's international table of GI. Information on morbidity and mortality was obtained through linkage with national registries. Cox proportional hazards analysis was performed to estimate hazard ratios (HRs for incident coronary heart disease (CHD and stroke, while adjusting for age, CVD risk factors, and dietary factors. RESULTS: During a mean follow-up of 11.9 years, 581 CHD cases and 120 stroke cases occurred among men, and 300 CHD cases and 109 stroke cases occurred among women. In men, GL was associated with an increased CHD risk (adjusted HR per SD increase, 1.17 [95% CI, 1.02-1.35], while no significant association was found in women (1.09 [0.89-1.33]. GI was not associated with CHD risk in both genders, while it was associated with increased stroke risk in men (1.27 [1.02-1.58] but not in women (0.96 [0.75-1.22]. Similarly, total carbohydrate intake and starch intake were associated with a higher CHD risk in men (1.23 [1.04-1.46]; and 1.24 [1.07-1.45], but not in women. CONCLUSION: Among men, high GL and GI, and high carbohydrate and starch intake, were associated with increased risk of CVD.

    The association of E670G (rs505151) polymorphism in PCSK9 gene with an increased risk of coronary artery disease (CAD) and ischemic stroke (IS) was reported in previous studies. We investigated the effect of the E670G (rs505151) on the risk of CAD and IS in a Tunisian cohort. Genotyping of the PCSK9 E670G was performed using polymerase chain reaction (PCR)-based restriction fragment length polymorphism (RFLP) and then confirmed by direct sequencing. The frequency of the 670G allele was significantly higher in the CAD than in the no-CAD subgroup (0.132 vs. 0.068, p = 0.030). As expected, the incidence of E670G was significantly important in IS subgroup than control group (0.122 vs. 0.073, p = 0.032). Furthermore in CAD patients, the 670G carriers showed significantly increased plasma total cholesterol and LDL-cholesterol levels compared to E670 carriers (6.78 [6.47-7.00] vs. 4.92 [4.02-5.46] mmol/l, p coronary arteries (0.068 vs. 0.198, p = 0.001, OR = 3.39 [1.55-7.37]). The E670G polymorphism of the PCSK9 gene is mainly associated with a increased risk and severity of CAD and IS in Tunisian cohort.

    Plasma protein S (PS) levels are reportedly low in patients with venous thrombosis but high in coronary heart disease (CHD) patients. The authors examined the association between free PS concentration and CHD or stroke risk and assessed risk in combination with C-reactive protein (CRP) levels. Free PS concentration was determined in 6 annual visits among 3,052 middle-aged (49-64 years) United Kingdom men from the Second Northwick Park Heart Study, with 297 CHD events from 1989 to 2005. The highest (vs. first) quintile was associated with a significantly increased CHD risk after adjustment for all other risk factors and correction for regression dilution bias (hazard ratio = 1.85, 95% confidence interval: 1.08, 3.16; P = 0.024). Models that included all well-known risk factors plus PS quintiles improved prediction of CHD (net reclassification improvement (NRI) = 7.0% (P = 0.007), category-less NRI (>0) = 22.1% (P < 0.001)), and the likelihood ratio statistic increased significantly (P = 0.018). The increase in CHD risk was particularly strong when subjects also had high CRP levels. There was no association between free PS level and stroke risk. This study confirms the independent association of elevated free PS levels with future risk of CHD, although elevated PS levels added only modestly to prediction metrics. The novel finding of increased CHD risk, particularly when CRP and PS levels are high, requires further study.

    Full Text Available Abstract Background Reports of higher quality care by higher-volume secondary care providers have fuelled a shift of services from smaller provider units to larger hospitals and units. In the United Kingdom, most patients are managed in primary care. Hence if larger practices provide better quality of care; this would have important implications for the future organization of primary care services. We examined the association between quality of primary care for cardiovascular disease achieved by general practices in England and Scotland by general practice caseload, practice size and area based deprivation measures, using data from the New General Practitioner (GP Contract. Methods We analyzed data from 8,970 general practices with a total registered population of 55,522,778 patients in England and Scotland. We measured practice performance against 26 cardiovascular disease (coronary heart disease, left ventricular disease, and stroke Quality and Outcomes Framework (QOF indicators for patients on cardiovascular disease registers and linked this with data on practice characteristics and census data. Results Despite wide variations in practice list sizes and deprivation, the prevalence of was remarkably consistent, (coronary heart disease, left ventricular dysfunction, hypertension and cerebrovascular disease was 3.7%; 0.45%; 11.4% and 1.5% respectively. Achievement in quality of care for cardiovascular disease, as measured by QOF, was consistently high regardless of caseload or size with a few notable exceptions: practices with larger list sizes, higher cardiovascular disease caseloads and those in affluent areas had higher achievement of indicators requiring referral for further investigation. For example, small practices achieved lower scores 71.4% than large practices 88.6% (P Conclusion The volume-outcome relationship found in hospital settings is not seen between practices in the UK in management of cardiovascular disorders in primary care

    Full Text Available Coronary CT angiography is widely recognised as a reliable imaging modality for the diagnosis of coronary artery disease. Coronary CT angiography not only provides excellent visualisation of anatomical changes in the coronary artery with high diagnostic value in the detection of lumen stenosis or occlusion, but also offers quantitative characterisation of coronary plaque components. Furthermore, coronary CT angiography allows myocardial perfusion imaging with diagnostic value comparable to the reference standard method. Coronary CT angiography-derived haemodynamic analysis has the potential to evaluate functional significance of coronary lesions. This review article aims to provide an overview of clinical applications of coronary CT angiography in coronary artery disease.

    Background The association of overall diet, as characterized by dietary patterns, with risk of incident acute coronary heart disease (CHD) has not been studied extensively in samples including sociodemographic and regional diversity. Methods and Results We used data from 17,418 participants in Reasons for Geographic and Racial Differences in Stroke (REGARDS), a national, population-based, longitudinal study of white and black adults aged ≥45 years, enrolled from 2003-2007. We derived dietary patterns with factor analysis, and used Cox proportional hazards regression to examine hazard of incident acute CHD events – nonfatal myocardial infarction and acute CHD death – associated with quartiles of consumption of each pattern, adjusted for various levels of covariates. Five primary dietary patterns emerged: Convenience, Plant-based, Sweets, Southern, and Alcohol and Salad. A total of 536 acute CHD events occurred over a median (IQR) 5.8 (2.1) years of follow-up. After adjustment for sociodemographics, lifestyle factors, and energy intake, highest consumers of the Southern pattern (characterized by added fats, fried food, eggs, organ and processed meats, and sugar-sweetened beverages) experienced a 56% higher hazard of acute CHD (comparing quartile 4 to quartile 1: HR = 1.56; 95% CI: 1.17, 2.08; P for trend across quartiles = 0.003). Adding anthropometric and medical history variables to the model attenuated the association somewhat (HR = 1.37; 95% CI: 1.01, 1.85; P = 0.036). Conclusions A dietary pattern characteristic of the southern US was associated with greater hazard of CHD in this sample of white and black adults in diverse regions of the US. PMID:26260732

    Full Text Available The single nucleotide polymorphisms (SNPs related to both coronary heart disease (CHD and ischemic stroke (IS in Chinese individuals have not been identified definitely. This study was developed to evaluate the genetic susceptibility to CHD and IS on the chromosome 9p21 and the adenosine triphosphate (ATP-binding cassette transporter A1 genes (ABCA1 in a Chinese Han population. Genotypes of the rs1333040, rs1333042, rs4977574, rs2066715 and rs2740483 SNPs were determined in 1134 unrelated patients (CHD, 565 and IS, 569 and 541 controls. The frequencies of the rs4977574 genotypes and alleles between CHD and control groups, and the rs2740483 genotypes and alleles between IS and control groups were different (p = 0.006–0.001. The subjects with rs1333042GG genotype and the carriers of the rs4977574G allele were associated with increased risk of CHD. The carriers of the rs4977574G allele were associated with increased risk of IS. However, the carriers of the rs2740483C allele had lower risk of IS than the non-carriers of the rs2740483C allele after controlling for potential confounders. The rs4977574GG-age (>60 year interaction increased the risk of CHD (p = 0.022, whereas the rs2740483CG/CC-body mass index (>24 kg/m2 interaction decreased the risk of IS (p = 0.035. The interactions of rs1333040-rs1333042 on the risk of CHD and IS were relatively strong, whereas the interactions of rs1333040-rs1333042-rs2066715 and rs1333040-rs1333042-rs2066715-rs2740483 on the risk of CHD, and rs1333040-rs1333042-rs4977574 and rs1333040-rs1333042-rs4977574-rs2740483 on the risk of IS were relatively weak. These findings suggest that some common variants on the chromosome 9p21 and ABCA1 and their interactions may significantly modify the risk of CHD and IS independent of effects on serum lipid levels.

  14. Impact of cigarette smoking on the relationship between body mass index and coronary heart disease: a pooled analysis of 3264 stroke and 2706 CHD events in 378579 individuals in the Asia Pacific region

    Directory of Open Access Journals (Sweden)

    2009-08-01

    Full Text Available Abstract Background Elevated levels of body mass index (BMI and smoking are well established lifestyle risk factors for coronary heart disease (CHD and stroke. If these two risk factors have a synergistic relationship, rigorous lifestyle modification may contribute to greater reduction in cardiovascular burden than previously expected. Methods A pooled analysis of individual participant data from 38 cohorts, involving 378,579 participants. Hazards ratios (HRs and 95% confidence intervals (CIs for BMI by cigarette smoking status were estimated using Cox proportional hazard models. Results During a mean follow-up of 3.8 years, 2706 CHD and 3264 strokes were recorded. There was a log-linear, positive relationship of BMI with CHD and stroke in both smokers and non-smokers with evidence of a synergistic effect of smoking on the association between BMI and CHD only: HRs (95% CIs associated with a 2 kg/m2 higher BMI were 1.13 (1.10 – 1.17 in current smokers and 1.09 (1.06 – 1.11 in non-smokers (p-value for interaction = 0.04. Conclusion Smoking amplifies the positive association between BMI and CHD but not stroke. If confirmed, these results suggest that effective strategies that target smoking cessation and weight loss are likely to have a greater impact than anticipated on reducing the burden of CHD.

    The National Death Index (NDI) is widely used to detect coronary heart disease (CHD) and cardiovascular disease (CVD) deaths, but its reliability has not been examined recently. We compared CHD and CVD deaths detected by NDI with expert adjudication of 4010 deaths that occurred between 2003 and 2013 among participants in the REGARDS (REasons for Geographic And Racial Differences in Stroke) cohort of black and white adults in the United States. NDI derived CHD mortality had sensitivity 53.6%, specificity 90.3%, positive predictive value 54.2%, and negative predictive value 90.1%. NDI-derived CVD mortality had sensitivity 73.4%, specificity 84.5%, positive predictive value 70.6%, and negative predictive value 86.2%. Among NDI-derived CHD and CVD deaths, older age (odds ratios, 1.06 and 1.04 per 1-year increase) was associated with a higher probability of disagreement with the adjudicated cause of death, whereas among REGARDS adjudicated CHD and CVD deaths a history of CHD or CVD was associated with a lower probability of disagreement with the NDI-derived causes of death (odds ratios, 0.59 and 0.67, respectively). The modest accuracy and differential performance of NDI-derived cause of death may impact CHD and CVD mortality statistics. © 2017 The Authors.

    2011-01-01

    The concept that atherosclerosis is an inflammation has been increasingly recognized,and subsequently resulted in great interest in revealing the inflammatory nature of the atherosclerotic process.More recently,a large body of evidence has supported the idea that inflammatory mechanisms play a pivotal role throughout all phases of atherogenesis,from endothelial dysfunction and the formation of fatty streaks to plaque destabilization and the acute coronary events due to vulnerable plaque rupture.Indeed,although triggers and pathways of inflammation are probably multiple and vary in different clinical entities of atherosclerotic disorders,an imbalance between anti-inflammatory mechanisms and pro-inflammatory factors will result in an atherosclerotic progression.Vascular endothelial dysfunction and lipoprotein retention into the arterial intima have been reported as the earliest events in atherogenesis with which inflammation is linked.Inflammatory has also been extended to the disorders of coronary microvasculature,and associated with special subsets of coronary artery disease such as silent myocardial ischemia,myocardial ischemia-reperfusion,cardiac syndrome X,variant angina,coronary artery ectasia,coronary calcification and in-stent restenosis.Inflammatory biomarkers,originally studied to better understand the pathophysiology of atherosclerosis,have generated increasing interest among researches and clinicians.The identification of inflammatory biomarkers and cellular/molecular pathways in atherosclerotic disease represent important goals in cardiovascular disease research,in particular with respect of the development of therapeutic strategies to prevent or reverse atherosclerotic diseases.

    Obtaining serum troponin levels in every patient with acute stroke is recommended in recent stroke guidelines, but there is no evidence that these contribute positively to clinical care. We sought to determine the clinical significance of measuring troponin levels in acute ischemic stroke patients. We reviewed 398 consecutive patients with acute ischemic stroke at a large academic institution from 2010 to 2012. Troponin levels were measured as a result of protocol in place during part of the study period. The mean age was 70 years (standard deviation ±16 years) and 197 (49.5%) were men. Chronic kidney disease was present in 78 (19.6%), coronary artery disease in 107 (26.9%), and atrial fibrillation in 107 (26.9%). Serum troponin T was measured in 246 of 398 patients (61.8%). Troponin was elevated (>.01 ng/mL) at any point in 38 of 246 patients (15.5%) and was elevated in 28 patients at all 3 measurements (11.3% of those with troponin measured). Only 4 of 246 patients (1.6%) had a significant uptrend. Two were iatrogenic in the setting of hemodynamic augmentation using vasopressors to maintain cerebral perfusion. One case was attributed to stroke and chronic kidney disease and another case to heart failure from inflammatory fibrocalcific mitral valvular heart disease. Serum troponin elevation in patients with ischemic stroke is not usually caused by clinically significant acute myocardial ischemia unless iatrogenic in the setting of vasopressor administration. Serum troponin levels should be measured judicially, based on clinical context, rather than routinely in all stroke patients. Copyright © 2016 National Stroke Association. Published by Elsevier Inc.

    Heterozygous familial hypercholesterolemia (FH) is the most common premature atherosclerotic cardiovascular disease (ASCVD)-related monogenic disorder, and it is associated with ischemic heart disease. There is limited information whether FH increases the risk of peripheral arterial and cerebrovascular disease. Our aim was to analyze ASCVD prevalence and characteristics in different arterial territories in a large FH population, to compare them with an unaffected control population and to determine which factors are associated to ASCVD. SAFEHEART (Spanish Familial Hypercholesterolaemia Cohort Study) is an ongoing registry of molecularly defined patients with heterozygous FH in Spain. ASCVD in the different arterial territories was analyzed, as well as individual characteristics, genetic variables, and lipid-lowering therapies. The study recruited 4132 subjects (3745 ≥18 years); 2,752 of those enrolled were molecularly diagnosed FH cases. Median age was 44.0 years (45.9% men) and 40 years (46.6% men) in FH patients and unaffected relatives (P50 mg/dL were independently associated with ASCVD. The prevalence of ASCVD is higher, and the involvement of the arterial territories is different in FH patients when compared with their unaffected relatives. Age, male sex, increased body mass index, hypertension, type 2 diabetes mellitus, smoking habit, and lipoprotein(a) >50 mg/dL were independently associated to ASCVD.

    Since smoking and exercise have opposite effects on coronary risk factors, the hypothesis was proposed that smoking might weaken the protective effect of exercise on prevention of coronary heart disease. To determine the effect of smoking on the relationship between sports participation and mortality from coronary heart disease. Population-based prospective cohort study in Japan. A total of 76 832 Japanese men and women, aged 40-79 years with no history of stroke, coronary heart disease, or cancer, completed a self-administered questionnaire between 1988 and 1990. Systematic mortality surveillance was carried out through 2003, and 638 deaths from coronary heart disease (496 myocardial infarction) were identified. People who reported the longest time in sports participation (>or=5 hours/week) had an approximately 50-80% lower age-adjusted risk of mortality from coronary heart disease compared with those in the second lowest category (1-2 hours/week) among never and ex-smokers, but no association was found among current smokers. Adjustment for known risk factors and exclusion of subjects who died within 2 years of the baseline inquiry did not substantially alter these associations. The multivariable hazard ratios (95% confidence interval) of coronary heart disease for the >or=5 hours/week versus 1-2 hours/week of sports participation were 0.44 (0.23 to 0.86) among never smokers, 0.18 (0.05 to 0.60) among ex-smokers, and 0.82 (0.47 to 1.40) among current smokers. Similar associations were found for men and women. Smoking may reduce the beneficial effect of sports participation for reduction of fatal coronary heart disease.

    Elevated lipoprotein-associated phospholipase A2 activity promotes the development of vulnerable atherosclerotic plaques, and elevated plasma levels of this enzyme are associated with an increased risk of coronary events. Darapladib is a selective oral inhibitor of lipoprotein-associated phospholipase A2. In a double-blind trial, we randomly assigned 15,828 patients with stable coronary heart disease to receive either once-daily darapladib (at a dose of 160 mg) or placebo. The primary end point was a composite of cardiovascular death, myocardial infarction, or stroke. Secondary end points included the components of the primary end point as well as major coronary events (death from coronary heart disease, myocardial infarction, or urgent coronary revascularization for myocardial ischemia) and total coronary events (death from coronary heart disease, myocardial infarction, hospitalization for unstable angina, or any coronary revascularization). During a median follow-up period of 3.7 years, the primary end point occurred in 769 of 7924 patients (9.7%) in the darapladib group and 819 of 7904 patients (10.4%) in the placebo group (hazard ratio in the darapladib group, 0.94; 95% confidence interval [CI], 0.85 to 1.03; P=0.20). There were also no significant between-group differences in the rates of the individual components of the primary end point or in all-cause mortality. Darapladib, as compared with placebo, reduced the rate of major coronary events (9.3% vs. 10.3%; hazard ratio, 0.90; 95% CI, 0.82 to 1.00; P=0.045) and total coronary events (14.6% vs. 16.1%; hazard ratio, 0.91; 95% CI, 0.84 to 0.98; P=0.02). In patients with stable coronary heart disease, darapladib did not significantly reduce the risk of the primary composite end point of cardiovascular death, myocardial infarction, or stroke.

    Full Text Available Atherosclerosis is the most common cause of myocardial infarction and ischemic stroke. Various risk factors have been identified for atherosclerosis. Recently, bacterial and viral organisms, which are involved in chronic inflammatory processes, have been also implicated in atherosclerosis development. Individuals with a prior history of periodontal diseases and/or tooth loss are considered to be at a higher risk for peripheral arterial disease, compared to those without periodontal diseases or tooth loss. Evidence suggests that periodontitis contributes to the overall burden of infection and inflammation and may lead to cardiovascular events and stroke in susceptible patients. In this article, we aimed to review the available data on the relationship between periodontal diseases and cardiovascular diseases, especially coronary artery disease. At least sixty papers were reviewed during 2014-15. Of these, 44 were included in our study.

    Full Text Available Neoangiogenesis in coronary heart disease is a protective reaction aimed to improve ischemic myocardial perfusion, by increasing the number and size of arterial collaterals. Placental growth factor (PlGF is one of the key peptides regulating angiogenic processes in atherosclerosis. In particular, a number of investigators have shown that injection of recombinant PlGF into the system or regional blood flow can stimulate neoangiogenesis. On the other hand, there is evidence confirming the involvement of PlGF in the progression of atherosclerosis and in the development of acute coronary syndrome. In this connection, the problem of investigating the efficiency and safety of possible use of PlGF preparations, as well as its place in the diagnosis of coronary heart disease and acute coronary syndrome remains urgent

    Background Percutaneous coronary intervention (PCI) is a well-established method for managing coronary diseases.However, the increasing use of PCI has led to an increased incidence of acute cerebrovascular accidents (CVA) related to PCI. In this study, we investigated the characteristics and risk factors of CVA after PCI in patients with known stroke history.Methods Between January 1, 2005 and March 1, 2009, 621 patients with a history of stroke underwent a total of 665 PCI procedures and were included in this retrospective study. Demographic and clinical characteristics, previous medications, procedures, neurologic deficits, location of lesion and in-hospital clinical outcomes of patients who developed a CVA after the cardiac catheterization laboratory visit and before discharge were reviewed.Results Acute CVA was diagnosed in 53 (8.5%) patients during the operation or the perioperative pedod. Seventeen patients suffered from transient ischemic attack, thirty-four patients suffered from cerebral infarction and two patients suffered from cerebral hemorrhage. The risk factors for CVA after PCI in stroke patients were: admission with an acute coronary syndrome, use of an intra-aortic balloon pump, urgent or emergency procedures, diabetes mellitus, and poor left ventricular systolic function, arterial fibrillation, previous myocardial infarction, dyslipidemia, tobacco use, and no/irregular use of anti-platelet medications.Conclusions The incidence of CVA during and after PCI in patients with history of stroke is much higher than that in patients without history of stroke. Patients with atrial fibrillation, previous myocardial infarction, diabetes mellitus,dyslipidemia, tobacco use, and no or irregular use of anti-platelet medications were at higher risk for recurrent stroke.This study showed a strong association between acute coronary syndromes and in-hospital stroke after PCI.

    2016-01-01

    Despite many advances in percutaneous and surgical interventions in the treatment of coronary artery disease (CAD), up to one-third of patients are still either not candidates or receive suboptimal revascularization. Calpains are a class of calcium-activated non-lysosomal cysteine proteases that serve as a proteolytic unit for cellular homeostasis. Uncontrolled activation of calpain has been found to be involved in the pathogenesis of myocardial reperfusion injury, cardiac hypertrophy, myocardial stunning and cardiac ischemia. Inhibition of calpains has been shown to significantly attenuate myocardial stunning and reduced infarct size after ischemia-reperfusion. Calpain inhibition therefore serves as a potential medical therapy for patients suffering from a number of diseases, including CAD.

    Stroke or cerebrovascular accident (CVA) is a devastating complication of coronary surgery. In this report, the incidence, and correlates of CVA following isolated coronary artery bypass grafting (CABG) surgery were evaluated. Data were collected retrospectively. Between 2006 and 2009, 855 patients underwent isolated CABG surgery. CVA was defined as any new neurological deficit lasting more than 24 hours. Univariate and multivariate analyses were utilized as appropriate. The incidence of CVA was 1.4% (n = 12). Age, previous CVA, and emergency surgery were correlated by univariate analysis. Multivariate analysis revealed age, previous CVA, and chronic renal impairment as predictors of CVA. Ten (83.3%) of the 12 patients were diagnosed to have CVA in the first 24 hours. Length of hospital stay was 20.9 ± 20.34 days for CVA patients and 9.2 ± 5.17 days for non-CVA patients (p ≤ 0.001). There were 4 (33.3%) deaths in CVA group and 27 (3.2%) for non-CVA patients (p = 0.001). Postoperative CVA is a major contributor to mortality, prolonged hospitalization, and other adverse postoperative complications. Further studies are needed to develop better strategies to minimize the occurrence of CVA among patients undergoing CABG. PMID:25317028

    Coronary artery disease (CAD) has been increasing during the last decade and is the one of major causes of death. The management of patients with coronary artery disease has evolved considerably. There are two main strategies in the management of CAD, complementary, not competitive, each other; the pharmacologic therapy to prevent and treat CAD and the percutaneous coronary intervention (PCI) to restore coronary flow. Antiplatelet drugs and cholesterol lowering drugs have central roles in pharmacotherapy. Drug eluting stent (DES) bring about revolutional changes in PCL in the management of patients with ST segment elevation acute myocardial infarction (AMI), there has been a debate on the better strategy for the restoration of coronary flow. Thrombolytic therapy is widely available and easy to administer, whereas primary PCI is less available and more complex, but more complete. Recently published evidences in the pharmacologic therapy including antiplatelet and statin, and PCI including DES and reperfusion therapy in patients with ST segment elevation AMI were reviewed.

  9. Acoustic detection of coronary artery disease.

    Science.gov (United States)

    Semmlow, John; Rahalkar, Ketaki

    2007-01-01

    Coronary artery disease (CAD) occurs when the arteries to the heart (the coronary arteries) become blocked by deposition of plaque, depriving the heart of oxygen-bearing blood. This disease is arguably the most important fatal disease in industrialized countries, causing one-third to one-half of all deaths in persons between the ages of 35 and 64 in the United States. Despite the fact that early detection of CAD allows for successful and cost-effective treatment of the disease, only 20% of CAD cases are diagnosed prior to a heart attack. The development of a definitive, noninvasive test for detection of coronary blockages is one of the holy grails of diagnostic cardiology. One promising approach to detecting coronary blockages noninvasively is based on identifying acoustic signatures generated by turbulent blood flow through partially occluded coronary arteries. In fact, no other approach to the detection of CAD promises to be as inexpensive, simple to perform, and risk free as the acoustic-based approach. Although sounds associated with partially blocked arteries are easy to identify in more superficial vessels such as the carotids, sounds from coronary arteries are very faint and surrounded by noise such as the very loud valve sounds. To detect these very weak signals requires sophisticated signal processing techniques. This review describes the work that has been done in this area since the 1980s and discusses future directions that may fulfill the promise of the acoustic approach to detecting coronary artery disease.

From 1997 to 2007, the death rate from CVD declined 27.8%. Mortality data for 2007 show that CVD (I00–I99; Q20–Q28) accounted for 33.6% (813 804) of all 2 243 712 deaths in 2007, or 1 of every 2.9 deaths in the United States. On the basis of 2007 mortality rate data, more than 2200 Americans die of CVD each day, an average of 1 death every 39 seconds. More than 150 000 Americans killed by CVD (I00–I99) in 2007 were life expectancy of 77.9 years. Coronary heart disease caused ≈1 of every 6 deaths in the United States in 2007. Coronary heart disease mortality in 2007 was 406 351. Each year, an estimated 785 000 Americans will have a new coronary attack, and ≈470 000 will have a recurrent attack. It is estimated that an additional 195 000 silent first myocardial infarctions occur each year. Approximately every 25 seconds, an American will have a coronary event, and approximately every minute, someone will die of one. Each year, ≈795 000 people experience a new or recurrent stroke. Approximately 610 000 of these are first attacks, and 185 000 are recurrent attacks. Mortality data from 2007 indicate that stroke accounted for ≈1 of every 18 deaths in the United States. On average, every 40 seconds, someone in the United States has a stroke. From 1997 to 2007, the stroke death rate fell 44.8%, and the actual number of stroke deaths declined 14.7%.

    Coronary angiography and brain computed tomography were preoperatively performed to evaluate the clinical condition of coronary artery disease and cerebrovascular disease in 101 patients (mean age, 68.4 years) with revascularization for arteriosclerosis obliterans. Eighty patients had hypertension, 12 had diabetes, and 26 had hyperlipidemia. Seventy-one patients (70.3%) had coronary stenosis. Significant stenoses in major coronary artery branches were confirmed in 35 patients, including 13 patients with old myocardial infarction. Coronary artery bypass grafting and percutaneous coronary angioplasty were performed in 2 and 7 patients with critical stenosis, respectively. Of 57 patients, who underwent brain computed tomography, abnormalities were found in 52 patients (91.2%), including cortical infarction in 9, lacunar infarction in 35, and leukoaraiosis in 27 patients. During the follow-up period 13 patients died (including 3 cases of myocardial infarction and 3 cases of stroke). Actuarial survival rate at 5 years was 80.4%. The influence of ischemic heart disease and cerebrovascular disease on early and late mortality after surgical reconstruction for peripheral occlusive vascular disease is significant. Using visual diagnostic techniques, such as coronary angiography and brain computed tomography, long term survivor should be closely observed for multiple arteriosclerotic vascular diseases.

  15. Coronary collateral circulation in patients of coronary ectasia with significant coronary artery disease.

    Directory of Open Access Journals (Sweden)

    Po-Chao Hsu

    Full Text Available OBJECTIVES: Patients with coronary ectasia (CE usually have coexisting coronary stenosis resulting in myoischemia. Coronary collateral plays an important role in protecting myocardium from ischemia and reducing cardiovascular events. However, limited studies investigate the role of CE in coronary collaterals development. METHODS: We evaluated 1020 consecutive patients undergoing coronary angiography and 552 patients with significant coronary artery disease (SCAD, defined as diameter stenosis more than 70%, were finally analyzed. CE is defined as the ectatic diameter 1.5 times larger than adjacent reference segment. Rentrop collateral score was used to classify patients into poor (grades 0 and 1 or good (grades 2 and 3 collateral group. RESULTS: 73 patients (13.2% had CE lesions which were most located in the right coronary artery (53.4%. Patients with CE had a lower incidence of diabetes (43.8% vs 30.1%, p = 0.03, higher body mass index (25.4±3.5 vs 26.7±4.6, p = 0.027 and poorer coronary collateral (58.2% vs 71.2%, p = 0.040. Patients with poor collateral (n = 331 had a higher incidence of CE (15.7% vs 9.5%, p = 0.040 and fewer diseased vessels numbers (1.96±0.84 vs 2.48±0.69, p<0.001. Multivariate analysis showed diabetes (odd ratio (OR 0.630, p = 0.026, CE (OR = 0.544, p = 0.048, and number of diseased vessels (OR = 2.488, p<0.001 were significant predictors of coronary collaterals development. CONCLUSION: The presence of CE was associated with poorer coronary collateral development in patients with SCAD.

    Full Text Available Kawasaki disease (KD is an acute vasculitis syndrome of unknown etiology. It occurs in infants and young children,affecting mainly small and medium-sized arteries, particularly the coronary arteries. Generalized microvasculitis occurs in the first 10 days, and the inflammation persists in the walls of medium and small arteries, especially the coronary arteries, and changes to coronary artery aneurysms.We report the case of a 10-month-old girl referred to our center three months after the onset of disease due to the aneurysmsof the coronary arteries. During the acute phase of her illness, she received 2 gr/kg intravenous gamma globulin; and afterher referral to us, the patient was treated by antiaggregant doses of acetylsalicylic acid (ASA (5 mg/kg and Warfarin (1 mg/daily. At three months’ follow-up, the aneurysms still persisted in the echocardiogram.

    The precise diagnosis of the presence of significant left main coronary artery disease has profound prognostic and therapeutic implications. Coronary cineangiography has shown to be imprecise and inaccurate to determine the percent stenosis of the left main coronary artery. We report a case with significant left main coronary artery disease in whom coronary cineangiography was in discordance with the clinical data and intravascular ultrasonography. Based on the intravascular ultrasound findings, the patient underwent coronary artery bypass graft surgery. Therefore, the intravascular ultrasonography may be the procedure of choice for assessing indeterminant left main coronary artery lesions by coronary angiography.

    Ischemic strokes may have distinct aetiologies, including several different intrinsic arterial pathological disorders. The diagnosis and understanding of these arterial diseases is critical for the correct management of stroke as different treatment approaches are undertaken according to the aetiology. Atherosclerosis is by far the most common arterial disease among adults, and other pathological processes include arterial dissection, small vessel disease, inflammatory and non-inflammatory vasculopathy and vasomotor disorders. In children, there are several vasculopathies responsible for vaso-occlusive disease such as sickle-cell anemia, acute regressive angiopathy and Moya-Moya disease, neurofibromatosis, dissections, vasculitis associated with intracranial and systemic infections. An overview of the major carotid and vertebral pathological diseases responsible for ischemic stroke in adults and children, highlighting the accuracy of the different imaging modalities for its diagnosis and the imaging appearance of these diseases, is given.

    Coronary heart disease research along genetic lines is difficult. Studies in molecular genetics of apolipoprotein and receptor variability appear most promising in the near future. However, unexpected discoveries and methodology may turn up that may completely change the field. Exclusive concentration on lipid research therefore should be avoided. It is likely that most advances will come from carefully designed studies that ask specific questions. Such research design is appropriate not only for laboratory studies but also for clinical and epidemiological investigations. The collaboration of clinicians, biochemists, geneticists, epidemiologists, and statisticians is likely to lead to better understanding of coronary heart disease.

    We aimed to provide a quantitative analysis of the 1-year clinical outcomes of patients with multisystem coronary artery disease who were included in recent randomized trials of percutaneous coronary intervention with multiple stenting versus coronary artery bypass graft surgery. An individual patient database was composed of 4 trials (Arterial Revascularization Therapies Study, Stent or Surgery Trial, Argentine Randomized Trial of Percutaneous Transluminal Coronary Angioplasty Versus Coronary Artery Bypass Surgery in Multivessel Disease 2, and Medicine, Angioplasty, or Surgery Study 2) that compared percutaneous coronary intervention with multiple stenting (N = 1518) versus coronary artery bypass graft surgery (N = 1533). The primary clinical end point of this study was the combined incidence of death, myocardial infarction, and stroke at 1 year after randomization. Secondary combined end points included the incidence of repeat revascularization at 1 year. All analyses were based on the intention-to-treat principle. After 1 year of follow-up, 8.7% of patients randomized to percutaneous coronary intervention with multiple stenting versus 9.1% of patients randomized to coronary artery bypass graft surgery reached the primary clinical end point (hazard ratio 0.95 and 95% confidence interval 0.74-1.2). Repeat revascularization procedures occurred more frequently in patients allocated to percutaneous coronary intervention with multiple stenting compared with coronary artery bypass graft surgery (18% vs 4.4%; hazard ratio 4.4 and 95% confidence interval 3.3-5.9). The percentage of patients who were free from angina was slightly lower after percutaneous coronary intervention with multiple stenting than after coronary artery bypass graft surgery (77% vs 82%; P = .002). One year after the initial procedure, percutaneous coronary intervention with multiple stenting and coronary artery bypass graft surgery provided a similar degree of protection against death, myocardial

    Kawasaki disease is an acute systematic angiitis, specifically affecting the coronary arteries in young children. Coronary aneurysms develop in 10 to 15% of patients with Kawasaki disease. The coronary aneurysm frequently changes into coronary stenosis and obstruction. Hitherto, we could observe and access the severity of these coronary lesions with the use of two dimensional echocardiography and selective coronary angiography. Angiography is the most sensitive means available for diagnosing significant coronary lesions and their severity. However, it is insensitive for detecting intraluminal minute and pathologic changes such as intimal thickening, regeneration of endothelium and thrombus. Recent advance in fiberscopie technology, enabled us to observe the inside of coronary artery percutaneously. We tried to use this angioscopic technique for the observation of coronary lesions in eight patients with Kawasaki disease at chronic stage.

    This study was planned to investigate the impact of severe bleeding and blood transfusion on the development of stroke after coronary surgery. This cohort study includes 2357 patients undergoing isolated CABG from the prospective European Coronary Artery Bypass Grafting (E-CABG) registry. Severity of bleeding was categorized according to the Universal Definition of Perioperative Bleeding (UDPB), E-CABG and PLATO definitions. Thirty patients (1.3%) suffered postoperative stroke. The amount of transfused red blood cell (RBC) (OR 1.10, 95%CI 1.03-1.18), preoperative use of unfractioned heparin (OR 4.49, 95%CI 1.91-10.60), emergency operation (OR 3.97, 95%CI 1.47-10.74), diseased ascending aorta (OR 4.62, 95%CI 1.37-15.65) and use of cardiopulmonary bypass (p = 0.043, OR 4.85, 95%CI 1.05-22.36) were independent predictors of postoperative stroke. Adjusted analysis showed that UDPB classes 3-4 (crude rate: 3.6% vs. 1.0%; adjusted OR 2.66, 95%CI 1.05-6.73), E-CABG bleeding grades 2-3 (crudes rate: 6.3% vs. 0.9%; adjusted OR 5.91, 95%CI 2.43-14.36), and PLATO life-threatening bleeding (crude rate: 2.5% vs. 0.6%, adjusted OR 3.70, 95%CI 1.59-8.64) were associated with an increased risk of stroke compared with no or moderate bleeding. Bleeding and blood transfusion are associated with an increased risk of stroke after CABG, which is highest in patients with severe bleeding. Copyright © 2016 IJS Publishing Group Ltd.

    The risk of stroke in patients hospitalized with an acute coronary syndrome (ACS) ranges from ischemic stroke in patients with ACS to help guide clinicians in the acute management of these high-risk patients. Data were obtained from 63,118 patients enrolled from April 1999 to December 2007 in the Global Registry of Acute Coronary Events (GRACE), a multinational registry involving 126 hospitals in 14 countries. A regression model was developed to predict the occurrence of in-hospital ischemic stroke in patients hospitalized with an ACS. The main study outcome was the development of ischemic stroke during the index hospitalization for an ACS. Eight risk factors for stroke were identified: older age, atrial fibrillation on index electrocardiogram, positive initial cardiac biomarkers, presenting systolic blood pressure ≥ 160 mm Hg, ST-segment change on index electrocardiogram, no history of smoking, higher Killip class, and lower body weight (c-statistic 0.7). The addition of coronary artery bypass graft surgery and percutaneous coronary intervention into the model increased the prediction of stroke risk. In conclusion, the GRACE stroke risk score is a simple tool for predicting in-hospital ischemic stroke risk in patients admitted for the entire spectrum of ACS, which is widely applicable to patients in various hospital settings and will assist in the management of high-risk patients with ACS.

    Cardiovascular disease remains the leading cause of death in most of the developed world despite advances in both prevention and treatment. At the same time, the incidence rates of cardiovascular disease differ greatly between the genders, with men more likely than women to manifest ischemic heart disease. This observation has prompted new research initiatives to explain the discrepancy in heart disease prevalence and incidence between the sexes. Whether androgens affect cardiovascular disease adversely remains a contentious issue, with some data pointing to a deleterious effect of androgens on lipid profiles, and other studies revealing androgens' possible benefits on cardiovascular function. This review will examine the relationship between the endogenous production of androgen as well as the exogenous replacement of testosterone in men and the possible links to cardiovascular disease. The role of testosterone in male cardiovascular health is not completely understood, and additional studies are needed to explain its effect on atherosclerosis and its complications.

    Objectives To analyze the results of coronary angiographies (GAG) in patients with single aortic valvular heart disease; To study the relationship between aortic valve diseases and coronary artery disease (CAD). Methods 105 patients with single aortic valvular heart disease before surgery underwent angiography. The data of clinical characteristics and angiographies were analyzed. Results 51 patients had symptoms of angina pectoris among 105 patients with single aortic valvular heart disease. Seven of them were confirmed coronary artery disease by angiographies. Although the incidence of angina in aortic valve stenosis group was significantly higher than that in aortic valve regurgitation, the probability of combination of CAD in aortic valve stenosis group was similar to the later. However, the probability of combination of CAD in degenerative aortic valve group was significantly higher than the groups of rheumatic, congenitally bicuspid aortic valves, and other causes (p <0.01).Conclusions Angina pectoris is not sensitive for diagnosis of CAD in single aortic valve heart disease.The probability of combination of CAD in degenerative aortic valve disease is higher than that in aortic valve disease with other causes. Coronary angiography is strongly suggested for these patients.

    Coronary Heart Disease (CHD) is associated with emotions, especially negative ones, namely anxiety and depression. Emotional Intelligence (EI) is a psychological model that consists of a variety of emotional skills. The aim of the present study was to examine the relation between different dimensions of Emotional Intelligence and coronary heart disease. A total of 300 participants were studied during a 3-year period in an attempt to partially replicate and further expand a previous study conducted in Greece among CHD patients, which indicated a strong association between certain dimensions of Emotional Intelligence and the incidence of CHD. All participants completed a self-report questionnaire, assessing several aspects of Emotional Intelligence. The results showed that there is a link between the regulation of emotions and the occurrence of CHD. The evidence reported in the present study makes stronger the claim that EI plays a significant role in the occurrence of CHD.

  3. [Is coronary artery disease different in women?].

    Science.gov (United States)

    Schiele, François; Chopard, Romain

    2014-01-01

    Coronary artery disease (CAD) is the primary cause of death in women. Although acute coronary syndrome (ACS) is relatively infrequent in young women, failure to recognize ACS in this population can incur a major risk and registry data show that there is still plenty of room for improvement in this area. Women may suffer from "classical" CAD with development of atherosclerosis with a delay of about 10 years as compared to men, reflecting hormonal protection in women. Besides this classical presentation, angina in women often corresponds to impaired microcirculation, a syndrome known to associate typical angina, demonstrable myocardial ischemia, but no lesions on the coronary angiography. Finally, spasm, spontaneous dissection or coronary thrombosis through endothelial rupture are more frequent in women. The influence of risk factors on the development of CAD is comparable in both women and men. Recent registry studies show that in France, in particular, diabetes, obesity, and smoking are all risk factors that are on the rise in women. In addition, certain other risk factors are more specific to women, namely psycho-social stress. The methods to evaluate risk and detect CAD were mainly developed in male study populations, and these tools thus perform less well in female patients. In case of ACS, women benefit just as much from invasive management, but are at greater risk of iatrogenic complications, particularly with anti-thrombotic therapy or during revascularization procedures.

    Although the incidence of coronary artery aneurysms has diminished in patients with Kawasaki disease, coronary artery involvement is still regarded as a major complication of the disease, significantly affecting morbidity and mortality. Recent technical advances in coronary CT angiography (CTA) and MR angiography (MRA) have led to the possibility of using these two imaging methods as minimally invasive alternatives to the more invasive diagnostic catheter angiography in evaluating coronary artery abnormalities, such as aneurysm, stenosis, and occlusion. In this article, we describe imaging techniques and findings of coronary CTA and MRA in Kawasaki disease. (orig.)

    The ideal management of concomitant carotid and coronary artery occlusive disease remains elusive. Although researchers have advocated the potential benefits of varying treatment strategies based on either concomitant or staged surgical treatment, there is no consensus in treatment guidelines among national or international clinical societies. Clinical studies show that coronary artery bypass grafting (CABG) with either staged or synchronous carotid endarterectomy (CEA) is associated with a high procedural stroke or death rate. Recent clinical studies have found carotid artery stenting (CAS) prior to CABG can lead to superior treatment outcomes in asymptomatic patients who are deemed high risk of CEA. With emerging data suggesting favorable outcome of CAS compared to CEA in patients with critical coronary artery disease, physicians must consider these diverging therapeutic options when treating patients with concurrent carotid and coronary disease. This review examines the available clinical data on therapeutic strategies in patients with concomitant carotid and coronary artery disease. A treatment paradigm for considering CAS or CEA as well as CABG and percutaneous coronary intervention is discussed.

    Background Kawasaki disease (KD) is the leading cause of pediatric ischemic heart disease. The incidence of serious coronary sequelae is low and about 2%-3% of patients with KD, but once myocardial infarction occurs in children, the mortality is quite high and 22% at the first infarction.This study aimed to evaluate the efficacy of coronary artery bypass grafting (CABG) in patients with KD.Methods Eight patients with a history of KD underwent CABG between October 1997 and July 2005. The number of bypass grafts placed was 2 to 4 per patient (mean 2.5±0.8). Various bypass grafts were used in patients, i.e. the left internal mammary artery (LIMA) in 3 patients, bilateral internal mammary artery (IMA) in 2 patients, LIMA plus gastroepiploic artery (GEA) in 1 patient and total saphenous vein grafts (SVGs) in 2 patients. The combined procedures included ventricular aneurysmectomy in 1 patient, mitral valve plasty in 1 and right coronary aneurysmectomy in 1. One patient was not able to wean from cardiopulmonary bypass (CPB), after being supported with intra-aortic balloon pump (IABP), the patient was weaned from CPB successfully.Results One patient died of low cardiac output syndrome and acute renal failure 19 days after operation. Other patients recovered and were discharged uneventfully. During the follow-up that ranged from 3 to 57 months (mean 27 months),clincal angina disappeared or improved. Cardiac function was in Class Ⅰ-Ⅱ (NYHA).Conclusion CABG is a safe and effective procedure for Kawasaki coronary artery disease. However long-term results need to be followed up.

    There are numerous associations between stress, mental disorders and coronary heart disease (CHD). Exposure to an acute stressor leads to activation of the hypothalamus-pituitary-adrenal and sympathoadrenal systems and chronic stressors are associated with sustained functional changes of these systems. Experiencing acute and chronic stress is paralleled by an increased incidence of mental disorders with the most consistent evidence on the triggering of major depressive episodes. Various mental disorders, including depression, anxiety and schizophrenia, are associated with an increased risk of CHD. Furthermore, acute and chronic stressors have been identified as risk factors or triggers of acute coronary syndromes. Thus therapeutic strategies aim at reducing subjective stress experience, therapy of mental disorders and treatment of cardiac risk factors known to be more prevalent in increased stress states and mental disorders.

Several complications may arise after coronary intervention for coronary lesions that interfere with treatment, and the incidence of coronary arterial complications due to invasive therapy remains unclear. Further, the long-term outcomes in patients with Behçet’s disease after stenting for acute myocardial infarction have not been described. The present report describes a 35-year-old Japanese man with Behçet’s disease who developed acute myocardial infarction. A coronary aneurysm developed at the stenting site of the left anterior descending coronary artery, along with stenosis in the left anterior descending segment proximal to the site. Although invasive therapy was considered, medication including immunosuppressants was selected because of the high risk of vascular complications after invasive therapy. The coronary artery disease has remained asymptomatic for the 4 years since the patient started medication. This case underscores the importance of considering the incidence of coronary arterial complications and of conservative treatment when possible.Keywords: Behçet’s disease, myocardial infarction, coronary arterial complications, percutaneous coronary intervention, immunosuppressants

    Anabolic steroids are frequently abused, thus increasing the risk of cardiovascular disease, despite the known unfavorable influence on lipid profiles. We report on a young bodybuilder who presented with ventricular tachycardia as the first manifestation of severe underlying coronary heart disease. Coronary angiogram revealed severe stenotic lesions in the right coronary artery and the left descending coronary artery, and hypokinetic regions corresponded to posterolateral and anterior myocardial infarctions. This young patient had a history without any coronary risk factors, but with a 2-year abuse of the anabolic steroid stanazolol. No report published so far has shown possible atherogenic consequences of long-term abuse of stanazolol.

    Background Coexistent carotid and coronary artery diseases are common and patients with them remain at a high risk for perioperative stroke or myocardial infarction after coronary bypass surgery.The aim of this study was to investigate the effect of combined carotid endarterectomy (CEA) and off-pump coronary artery bypass grafting (CABG) in patients with coexistent carotid and coronary artery diseases.Methods Between January 2002 and December 2007, consecutive patients with coexistent carotid and coronary artery diseases underwent one-stage unilateral CEA and off-pump CABG in Heart institute of Nanjing First Hospital Affiliated to Nanjing Medical University. Perioperative complications were assessed and follow-up was carried out. Results A total of 51 cases of isolated off-pump CABG and unilateral CEA, including 34 right and 17 left, were performed. The mean blocked time of carotid artery in CEA was (25.5±7.0) minutes. The mean number of distal grafts per patient was 3.30±0.45. The mean ventilation time, intensive care unit stay, and postoperative hospital stay was (11.3±5.4) hours, (2.1 ±0.9) days, and (12.5±6.1) days respectively. None of the patients had stroke or myocardial infarct. There was one perioperative death due to acute cardiac failure, resulting in an operative mortality of 1.96%. Follow-up was completed for 47 patients (92.16%) with a mean follow-up of (39.5±12.5) months. None of the patients manifested stroke, new angina or newly developed cardiac infarct. No late death occurred.Conclusion Combined CEA and off-pump CABG is a safe and effective procedure in selected patients with coexistent carotid and coronary artery diseases.

    Full Text Available The aim of this study is to investigate the relationship between intraluminal appearances of coronary plaques and left coronary bifurcation angle and plaque components using coronary CT virtual intravascular endoscopy (VIE. Fifty patients suspected of coronary artery disease undergoing coronary CT angiography were included in the study. The left bifurcation angle in patients with diseased left coronary artery which was measured as 94.3° ± 16.5 is significantly larger than that in patients with normal left coronary artery, which was measured as 76.5° ± 15.9 (P<0.001. Irregular VIE appearances were found in 10 out of 11 patients with mixed plaques in the left anterior descending (LAD and left circumflex (LCx, while, in 29 patients with calcified plaques in the LAD and LCx, irregular VIE appearances were only noticed in 5 patients. Using 80° as a cut-off value to determine coronary artery disease, smooth VIE appearances were found in 95% of patients (18/19 with left bifurcation angle of less than 80°, while irregular VIE appearances were observed in nearly 50% of patients (15/31 with left bifurcation angle of more than 80°. This preliminary study shows that VIE appearances of the coronary lumen are directly related to the types of plaques.

    Objective: To study whether adiponectin in serum of patients with coronary heart disease is reduced, and compare with the test results in total cholesterol (TC), Triglyceride (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), blood glucose (GLU), C-reactive protein (CRP). Method: We selected 80 cases of coronary heart disease patients as the experimental group, 50 healthy subjects as control group. The coronary heart disease group compared with the control group, we know the changes of adiponectin in coronary heart disease group and compared coronary heart disease group with control group in test results of blood lipid, blood glucose, C-reactive protein. Results: Adiponectin in coronary heart disease group was (0.47±0.09) mg/L, which decreased significantly comparing to control group’s level (t=-18.4, P<0.001), HDL-C in coronary heart disease group was (1.24±0.04) mmol/L, which decreased significantly comparing to control group’s level (t=-27.67, P<0.001). The difference was statistically significant (P<0.05). Conclusion: The level’s adiponectin in patients of coronary heart disease dropped, which lead to hypoadiponectinemia, Hypoadiponectinemia may be one of the risk factors of coronary heart disease.

    Atherosclerosis is an inflammatory disease, and several inflammatory biomarkers, such as C-reactive protein, have been used to predict the risk of coronary heart disease. High white blood cell count is a strong and independent predictor of coronary risk in patients of both sexes, with and without coronary heart disease. A high number of white blood cells and their subtypes (for example, neutrophils, monocytes, lymphocytes, and eosinophils) are associated with the presence of coronary heart disease, peripheral arterial disease, and stroke. The coronary heart disease risk ratios associated with a high white blood cell count are comparable to those of other inflammatory markers, including C-reactive protein. In addition, other components of the complete blood count, such as hematocrit and the erythrocyte sedimentation rate, also are associated with coronary heart disease, and the combination of the complete blood count with the white blood cell count can improve our ability to predict coronary heart disease risk. These tests are inexpensive, widely available, and easy to order and interpret. They merit further research.

    Whether PR prolongation independently predicts new-onset ischemic events of myocardial infarction and stroke was unclear. Underlying pathophysiological mechanisms of PR prolongation leading to adverse cardiovascular events were poorly understood. We investigated the role of PR prolongation in pathophysiologically-related adverse cardiovascular events and underlying mechanisms. We prospectively investigated 597 high-risk cardiovascular outpatients (mean age 66 ± 11 yrs.; male 67%; coronary disease 55%, stroke 22%, diabetes 52%) for new-onset ischemic stroke, myocardial infarction (MI), congestive heart failure (CHF), and cardiovascular death. Vascular phenotype was determined by carotid intima-media thickness (IMT). PR prolongation >200 ms was present in 79 patients (13%) at baseline. PR prolongation >200 ms was associated with significantly higher mean carotid IMT (1.05 ± 0.37 mm vs 0.94 ± 0.28 mm, P = 0.010). After mean study period of 63 ± 11 months, increased PR interval significantly predicted new-onset ischemic stroke (P = 0.006), CHF (P = 0.040), cardiovascular death (P 200 ms. Using multivariable Cox regression, PR prolongation >200 ms independently predicted new-onset ischemic stroke (HR 8.6, 95% CI: 1.9-37.8, P = 0.005), cardiovascular death (HR 14.1, 95% CI: 3.8-51.4, P PR interval predicts new-onset MI at the exploratory cut-off >162 ms (C-statistic 0.70, P = 0.001; HR: 8.0, 95% CI: 1.65-38.85, P = 0.010). PR prolongation strongly predicts new-onset ischemic stroke, MI, cardiovascular death, and combined cardiovascular endpoint including CHF in coronary patients or risk equivalent. Adverse vascular function may implicate an intermediate pathophysiological phenotype or mediating mechanism.

    Tests to evaluate haemostatic function bleeding time (BT), prothrombin time (PT) partial thromboplastin time with kaolin (PTTK), thrombin time (TT), platelet count, platelet function tests (platelet adhesiveness and microthrombus index) and plasma fibrinogen levels were performed in 30 patients of coronary artery disease (14 myocardial infarction, 16 angina pectoris) and 20 age and sex matched controls. There was no statistically significant difference in platelet adhesiveness and mean microthrombus index in patients and controls. The BT, PT, PTTK and TT were normal in all patients and controls. Stepwise logistic regression analysis showed that plasma fibrinogen was an independent risk factor in the production of CAD.

    Full Text Available Coronary heart disease (CAD results from an interaction of different somatic, environmental and behavioral risk factors. Commonly, development of CAD is associated with arterial hypertension, dyslipidemia, diabetes mellitus, smoking, sedentary life style and the like. Psychological factors in their own sake or in combination with other risk factors are also important for genesis of CAD. In this study, 170 people that were diagnosed with CAD and 170 healthy controls of corresponding sex and age were compared for anxiety, aggressiveness and Eysenck's two personality dimension. The data indicate that patients with CAD have very low level of anxiety and aggressiveness and very high level of neuroticism relative to the controls. .

    To evaluate the usefulness of systematic coronary angiography followed, if needed, by coronary artery angioplasty (percutaneous coronary intervention (PCI)) on the incidence of cardiac ischaemic events after carotid endarterectomy (CEA) in patients without evidence of coronary artery disease (CAD). From January 2005 to December 2008, 426 patients, candidates for CEA, with no history of CAD and with normal cardiac ultrasound and electrocardiography (ECG), were randomised into two groups. In group A (n=216) all the patients had coronary angiography performed before CEA. In group B, all the patients had CEA without previous coronary angiography. In group A, 66 patients presenting significant coronary artery lesions at angiography received PCI before CEA. They subsequently underwent surgery under aspirin (100 mg day(-1)) and clopidogrel (75 mg day(-1)). CEA was performed within a median delay of 4 days after PCI (range: 1-8 days). Risk factors, indications for CEA and surgical techniques were comparable in both groups (p>0.05). The primary combined endpoint of the study was the incidence of postoperative myocardial ischaemic events combined with the incidence of complications of coronary angiography. Secondary endpoints were death and stroke rates after CEA and incidence of cervical haematoma. Postoperative mortality was 0% in group A and 0.9% in group B (p=0.24). One postoperative stroke (0.5%) occurred in group A, and two (0.9%) in group B (p=0.62). No postoperative myocardial event was observed in group A, whereas nine ischaemic events were observed in group B, including one fatal myocardial infarction (p=0.01). Binary logistic regression analysis demonstrated that preoperative coronary angiography was the only independent variable that predicted the occurrence of postoperative coronary ischaemia after CEA. The odds ratio for coronary angiography (group A) indicated that when holding all other variables constant, a patient having preoperative coronary angiography

    Diet plays an important part in the maintenance of optimal cardiovascular health. This Review summarizes the evidence for a relationship between fruit and vegetable consumption and the occurrence of coronary heart disease. This evidence is based on observational cohort studies, nutrition prevention trials with fruit and vegetables, and investigations of the effects of fruit and vegetables on cardiovascular risk factors. Most of the evidence supporting a cardioprotective effect comes from observational epidemiological studies; these studies have reported either weak or nonsignificant associations. Controlled nutritional prevention trials are scarce and the existing data do not show any clear protective effects of fruit and vegetables on coronary heart disease. Under rigorously controlled experimental conditions, fruit and vegetable consumption is associated with a decrease in blood pressure, which is an important cardiovascular risk factor. However, the effects of fruit and vegetable consumption on plasma lipid levels, diabetes, and body weight have not yet been thoroughly explored. Finally, the hypothesis that nutrients in fruit and vegetables have a protective role in reducing the formation of atherosclerotic plaques and preventing complications of atherosclerosis has not been tested in prevention trials. Evidence that fruit and vegetable consumption reduces the risk of cardiovascular disease remains scarce thus far.

    To assess the effects of residual coronary artery disease (non-revascularized coronary vessels) after coronary artery bypass grafting on symptoms and exercise left ventricular function, we categorized 77 patients into 3 groups according to the extent of residual coronary artery disease: group I (n = 17) had no residual coronary artery disease (residual score = 0); group II (n = 30) had light residual coronary artery disease (score of 1 to 9, mean 4.7); and group III (n = 30) had moderate residual coronary artery disease (score greater than or equal to 10, mean 23). Sixty patients were asymptomatic after coronary artery bypass grafting (14 in group I, 24 in group II, and 22 in group III), but the remaining patients had occasional angina pectoris. The resting left ventricular ejection fraction was significantly higher in group I than in the remaining 2 groups (56 +/- 18% in group I, 47 +/- 19% in group II, and 43 +/- 16% in group III, P less than 0.05). The exercise left ventricular ejection fraction was also significantly higher in group I (61 +/- 16% in group I, 51 +/- 18% in group II and 45 +/- 18% in group III, P less than 0.01). The ejection fraction response to exercise was abnormal in 5 patients in group I, 15 patients in group II, and 19 patients in group III. Thus, coronary artery bypass grafting results in symptomatic improvement, even in patients with residual coronary artery disease. The presence of residual coronary artery disease, however, may be a determinant of exercise left ventricular function in these patients.

    Background Angina without significant stenosis, or nonobstructive coronary artery disease, attracts clinical attention. Microvascular coronary artery spasm (microvascular CAS) can cause nonobstructive coronary artery disease. We investigated the clinical features of microvascular CAS and the therapeutic efficacy of calcium channel blockers. Methods and Results Three hundred seventy consecutive, stable patients with suspected angina presenting nonobstructive coronary arteries (<50% diameter) in coronary angiography were investigated with the intracoronary acetylcholine provocation test, with simultaneous measurements of transcardiac lactate production and of changes in the quantitative coronary blood flow. We diagnosed microvascular CAS according to lactate production and a decrease in coronary blood flow without epicardial vasospasm during the acetylcholine provocation test. We prospectively followed up the patients with calcium channel blockers for microvascular coronary artery disease. We identified 50 patients with microvascular CAS who demonstrated significant impairment of the endothelium-dependent vascular response, which was assessed by coronary blood flow during the acetylcholine provocation test. Administration of isosorbide dinitrate normalized the abnormal coronary flow pattern in the patients with microvascular CAS. Multivariate logistic regression analysis indicated that female sex, a lower body mass index, minor–borderline ischemic electrocardiogram findings at rest, limited–baseline diastolic-to-systolic velocity ratio, and attenuated adenosine triphosphate–induced coronary flow reserve were independently correlated with the presence of microvascular CAS. Receiver-operating characteristics curve analysis revealed that the aforementioned 5-variable model showed good correlation with the presence of microvascular CAS (area under the curve: 0.820). No patients with microvascular CAS treated with calcium channel blockers developed cardiovascular

    It is unclear if anomalous coronary arteries are at higher risk for atherosclerosis. The link between anomalous coronary artery and early coronary artery disease has been suggested. The aim of this study is to determine whether the coronary artery anomaly predisposes to development of significant coronary disease. Using retrospective chart review, patients with documented anomalous coronary arteries recognized during coronary angiography between years 2000 to 2007 were analyzed. Prevalence of significant atherosclerotic coronary artery disease (defined as more than 50% luminal narrowing) was compared between normal and anomalous coronaries. A total of 147 patients with anomalous coronary arteries were found. Right coronary artery was the most common anomalous artery 128 of 148 (86.5%) in our dataset. There was no difference in the occurrence of atherosclerosis between anomalous and nonanomalous coronaries. Significant atherosclerosis was present in 59 of the 148 anomalous coronary arteries (37.8%), and 112 of the 293 nonanomalous coronary arteries (38.2%, p = 0.9). On the basis of our study, there is no evidence that anomalous coronary arteries predispose to significant coronary artery disease in comparison to normal coronary arteries.

    Over the past 10 years it has become clear that passive smoking is correlated with an increased risk of coronary heart disease. The relative risk of 25-30% is comparable to that of lung cancer due to passive smoking. Since coronary heart disease is the most common cause of death, it is likely that p

    2013-03-26

    Coronary artery involvement is seen in approximately 15-20% of children with Kawasaki disease. There is conflicting literature regarding the clinical and laboratory findings associated with coronary artery involvement. In this retrospective study, we attempt identification of predictive factors for coronary artery involvement at our institute and review the existing literature. A review of 203 patients (65% males) with Kawasaki disease was performed, of whom 33 (16.3%) had coronary artery involvement. High erythrocyte sedimentation rate, high platelet count, low hematocrit, low albumin levels, and refractory Kawasaki disease showed significant association with coronary artery involvement. High erythrocyte sedimentation rate and refractory Kawasaki disease were found to be independent predictors of coronary artery involvement. Review of literature suggested a wide range of coronary involvement (60%), and highly conflicting clinical and laboratory associations. It remains difficult to accurately determine risk of coronary artery involvement, although some laboratory markers may provide information that is helpful for parental counseling and clinical follow up. Future identification of novel biomarkers and host predispositions may further our understanding of coronary artery risks and help personalize therapy for Kawasaki disease.

    Both adult and pediatric patients with sickle cell disease face a higher risk of stroke than the general population. Given the different underlying pathophysiology predisposing these patients to stroke, providers should be aware of differences in guidelines for stroke management. This paper reviews diagnostic considerations and recommendations during the evaluation and acute management of patients with sickle cell disease presenting with stroke, focusing on recent updates in the literature. Given the high recurrence rate of stroke in these patients, secondary prevention and curative measures will also be reviewed.

    Abstract The plasma levels of asymmetric dimethylarginine (ADMA) had been proved to be an independent cardiovascular risk factor. Few studies involved the entire arginine methylation dysfunction. This study was designed to investigate whether arginine methylation dysfunction is associated with acute coronary syndrome risk in coronary artery disease population. In total 298 patients undergoing coronary angiography because of chest pain with the diagnosis of stable angina pectoris or acute coronary syndrome from February 2013 to June 2014 were included. Plasma levels of free arginine, citrulline, ornithine, and the methylated form of arginine, ADMA, and symmetric dimethylarginine (SDMA) were measured with high-performance liquid chromatography coupled with tandem mass spectrometry. We examined the relationship between arginine metabolism-related amino acids or arginine methylation index (AMI, defined as ratio of [arginine + citrulline + ornithine]/[ADMA + SDMA]) and acute coronary events. We found that plasma ADMA levels were similar in the stable angina pectoris group and the acute coronary syndrome group (P = 0.88); the AMI differed significantly between 2 groups (P angina and acute coronary syndrome patients; AMI might be an independent risk factor of acute coronary events in coronary artery disease population.

    Coronary heart disease (CHD), traditionally considered a male disease, causes far more deaths in women than cancer. The prevalence of CHD is lower in women at any age, but with advancing age, this differential decreases. The clinical outcomes including myocardial infarction mortality, all-cause mortality, and reinfarction rates are also worse in women with cardiovascular diseases (CVD) than in men. Yet, women appear to be underdiagnosed and undertreated for coronary heart disease. There is still a gap in the knowledge, understanding, and general awareness of CHD in women. This review provides updates in gender disparities in the management of risk factors, treatments, and outcomes of coronary heart disease.

    To demonstrate whether there is a relationship between the presence of nonalcoholic fatty liver disease (NAFLD) and the presence and extent of coronary artery disease (CAD). Ninety-two consecutive patients who planned to undergo coronary angiographies (CAG) without known CAD, other than findings of acute coronary syndrome, were enrolled in this study. Abdominal ultrasonography was performed before the CAG to detect NAFLD. CAD was defined as a stenosis of at least 50% in at least one major coronary artery. The extent of CAD was measured according to the number of major coronary artery/arteries affected by CAD. All the risk factors for CAD were included in a binary logistic regression model. Forward, backward, or step-wise selections were not used. P<0.05 was accepted as being significant. Sixty-five of the 92 patients (70.7%) were detected, by abdominal ultrasonography, to have fatty liver and 43 patients out of 92 (46.7%) were detected, by CAG, to have significant CAD. According to the results of logistic regression analysis, the presence of NAFLD independently increased the risk for CAD, as seen in CAG [odds ratio (OR), 95% confidence interval (CI): 6.73 (1.14-39.61); P=0.035]; this was despite factoring in the other risk factors for CAD and the components of metabolic syndrome. NAFLD was more commonly found in patients as the extent of CAD increased (P=0.001). The presence of NAFLD is independently associated with the presence and extent of CAD. Future studies are needed to explain the mechanisms of this relationship.

  4. "Obesity paradox" in coronary artery disease.

    2015-10-26

    Obesity used to be among the more neglected public health problems, but has unfolded as a growing medical and socioeconomic burden of epidemic proportions. Morbid obesity is linked to traditional cardiovascular risk factors like, hypertension, hyperlipidemia and diabetes, and suspected to incur increased morbidity and mortality in the Western and even third world populations. This patient cohort is also at greater risk to develop coronary artery disease. Recent population-based registries revealed that 43% and 24% of all cases of coronary revascularization were carried out in overweight and obese patients, respectively. However, despite evidence of a positive correlation between obesity and increased cardiovascular morbidity, some authors have described a better clinical outcome in overweight and obese patients, a phenomenon they coined "obesity paradoxon". Thus, there is an ongoing debate in light of conflicting data and the possibility of confounding bias causing misconception and challenging the "obesity paradox". In this review article we present the current evidence and throughly discuss the validity of the "obesity paradoxon" in a variety of clinical settings.

    Full Text Available BACKGROUND Cardiovascular disease is the leading cause of death among women regardless of race or ethnicity accounting for deaths of 1 in 3 women. The aim of the study is to identify the important risk factors contributing to the coronary artery disease in Indian women. MATERIALS AND METHODS Study conducted on 120 women patients of age >40 yrs. visiting a female outpatient department of Jawahar Lal Nehru Medical College, Bhagalpur, who presented with complaints related to CAD cases diagnosed from the electrocardiogram findings, clinical features and biochemical marker as per World Health Organization guidelines. RESULTS 50-59 years age group is most effected group in study with 44.2%. Most of the women are of postmenopausal age group. The maximum number of cases was seen in upper lower socioeconomic status (37.5% followed by lower (19.2%. CAD incidence was minimum in upper class. Chest pain was the main complaint in patients, next in frequency was sweating and followed by breathlessness. The major risk factors in the study group were hypertension (74.1, diabetes (63.3, sedentary habits (49.1, stress (34.2, family history (29.2 and tobacco consumption (21.8. 25 patients had obesity and 54 peoples were overweight. In our study, 48 patients had 3 children, 19 had more than 3 children. 61.7% of the patients are with hypercholesterolaemia, which most of the patients found with 2 vessel block is most common blocks observed. CONCLUSION Despite this delay in onset, mortality from coronary heart disease is increasing more rapidly among women than men.

    Full Text Available Abstract Introduction Cerebrovascular disease is a major cause of mortality and morbidity worldwide. Ischemic stroke is the most common manifestation, encompassing a wide variety of causative mechanisms. We present the case of a middle-aged male patient with spontaneous coronary artery dissection in the presence of anti-cardiolipin antibodies, leading to left ventricular thrombus and presenting with stroke. Case presentation A 56-year-old Caucasian man presented with dysarthria and right-sided weakness. There was a history of chest pain with autonomic symptoms four days earlier. Examination revealed right-sided hemiparesis. Electrocardiogram showed sinus rhythm with anterior Q waves. Magnetic resonance imaging of the brain showed large left parietal and smaller multiple cerebral infarcts. Echocardiogram showed anterior wall and apical akinesis with a large mural thrombus. Anti-cardiolipin antibodies immunoglobulin G and immunoglobulin M were strongly positive. Coronary angiography showed dissection of the mid left anterior descending artery with normal flow down the distal vessel. He was treated conservatively with anticoagulation and secondary prevention. He was in good health when seen in clinic four months later. Conclusion We highlight the importance of a comprehensive approach at obtaining the correct diagnosis, input of different specialities and the fact that the presence of anti-cardiolipin antibodies is associated with coronary artery dissection in a middle-aged male patient whose presentation was stroke.

    Full Text Available Background: Aortic valve sclerosis (AVS is characterized by increased thickness, calcification and stiffness of the aortic leaflets without fusion of the commissures. Several studies show an association between AVS and presence of coronary artery disease. Objective: The aim of this study is to investigate the association between presence of AVS with occurrence of previous coronary artery disease and classical risk factors. Methods: The sample was composed of 2,493 individuals who underwent transthoracic echocardiography between August 2011 and December 2012. The mean age of the cohort was 67.5 ± 15.9 years, and 50.7% were female. Results: The most frequent clinical indication for Doppler echocardiography was the presence of stroke (28.8%, and the most common risk factor was hypertension (60.8%. The most prevalent pathological findings on Doppler echocardiography were mitral valve sclerosis (37.1% and AVS (36.7%. There was a statistically significant association between AVS with hypertension (p < 0.001, myocardial infarction (p = 0.007, diabetes (p = 0.006 and compromised left ventricular systolic function (p < 0.001. Conclusion: Patients with AVS have higher prevalences of hypertension, stroke, hypercholesterolemia, myocardial infarction, diabetes and compromised left ventricular systolic function when compared with patients without AVS. We conclude that there is an association between presence of AVS with previous coronary artery disease and classical risk factors.

    The diagnosis of cardiac ischemia related to coronary artery disease (CAD) is a clinical challenge. Despite many methods clinically available, the predictive value of each is still limited. Magnetocardiography (MCG) offers new insights in the electrogenesis of the disease. In the last decade a number of studies using biomagnetometers have dealt with the identification of CAD patients using coronary angiography as a gold standard. As the availability of these systems is limited, studies have focused either on exercise-induced ischemia or on chronic ischemia and the infarct scar at rest. Different parameters have been developed based on signal morphology, time intervals, source parameters or magnetic field map analysis. Concerning signal morphology, main work concentrates on ST-depression, ST-T signal amplitude as well as QRS and ST-T integrals. Dealing with time intervals, most studies focus on the QT interval. The evaluation of of QT dispersion spatially in the MCG, reflecting regional heterogeneity of repolarization, improved the identification of CAD patients. Besides the calculation of the equivalent current dipole during de- and repolarization, parameters of the magnetic field orientation were used to identify CAD patients and localize exercise-induced ischemic regions. Heart rate adjusted alteration in the magnetic field orientation allowed the quantification of ischemia-induced changes in MCG. The estimation of current density (CDV) further enabled to separate healthy subjects from CAD patients at rest. In the course of interventional therapy CDV maps returned toward that of healthy subjects.Thus, there is justification for routine clinical use of the MCG in the diagnosis of CAD.

    2012-11-01

    Cardiac complications following stroke or acute cerebrovascular accidents (CVA) are common; however, many of these complications are asymptomatic and do not cause adverse cardiac effects. Symptomatic events (such as acute myocardial infarction after CVA) rarely occur and are often the result of an underlying cardiac embolic source, such as a left ventricular thrombus. We report a case of spontaneous coronary thrombosis following thrombolytic therapy for acute CVA, and discuss the implication that an underlying systemic pro-thrombotic state may predispose individuals to thrombosis in disparate vascular beds.

    Kawasaki disease refers to systemic vasculitis with risk of coronary artery disease. Our objective is to identify risk factors associated with coronary artery disease in patients with complete and incomplete Kawasaki disease. Descriptive, retrospective study conducted in patients diagnosed with Kawasaki disease in a tertiary-care hospital between 2008 and 2014. The American Heart Association diagnostic criteria were used to define complete and incomplete Kawasaki disease. Thirty-one children were diagnosed with Kawasaki disease; 24 met the criteria for the complete form, and 7, for the incomplete form of this condition. Five had coronary artery disease. One of them had incomplete Kawasaki disease (1/7= 14.3%), and the remaining four had the complete form (4/24= 16.7%). No significant differences were found between both groups (p= 1.0). Patients with coronary artery involvement had a higher C-reactive protein level (median: 16.2 mg/dL versus 8.4 mg/dL, p= 0.047) and lower albuminemia (median: 3.2 mg/dL versus 3.99 mg/dL, p= 0.002). The risk of coronary artery involvement in incomplete Kawasaki disease is similar to that in complete Kawasaki disease; therefore, in patients with the incomplete form, immunoglobulin therapy should not be delayed. In our population, C-reactive protein and albumin levels were related to a higher risk of coronary artery involvement. Sociedad Argentina de Pediatría.

    Full Text Available Background: Coronary artery bypass graft (CABG and percutaneous revascularisations with implantation of drug-eluting stents (DES are important treatment methods in coronary heart disease (CHD. Research questions: The evaluation addresses questions on medical efficacy, health economic parameters as well as ethic, social and legal implications in the use of DES vs. CABG in CHD patients. Methods: A systematic literature search was conducted in December 2006 in the most important electronic databases beginning from 2004. Register data and controlled clinical studies were included in the evaluation. Additionally, a health economic modelling was conducted. Results: Medical evaluation: The literature search yielded 2,312 hits. 14 publications about six controlled clinical studies and five publications about two registers were included into the evaluation. Register data showed low mortality (0.2% to 0.7% and low rates of myocardial infarction (0.5% to 1.4% during hospital stay. In patients with stenosis of the left anterior descending coronary artery one study showed in several analyses a significantly higher rate of reinterventions and a significantly higher rate of repeated angina pectoris for DES up to two years after the implantation (16.8% vs. 3.6% and 35% vs. 8%. In patients with left main coronary artery stenosis two studies revealed a significantly higher survival without myocardial infarction and stroke for DES up to one year (96% vs. 79% and 95% vs. 91% and two studies a significantly higher rate of revascularisations up to two years (20% vs. 4% and 25% vs. 5% after the primary intervention. In patients with multivessel disease, one study found a significantly higher mortality and myocardial infarction rate for CABG at one year (2.7% vs. 1.0% and 4.2% vs. 1.3%. The rate of revascularisations was significantly higher in two studies up to two years after DES implantation (8.5% vs. 4.2% and 14.2% vs. 5.3%. The rate at repeated angina pectoris was

    Full Text Available Cognitive impairments (CIs are common in poststroke patients. The basis for this condition is frequently a neurodegenerative process and most often Alzheimer's disease (AD. Stroke may promote the manifestation of clinically asymptomatic AD, worsen prestroke cognitive deficit or merely manifest prestroke CIs.The paper discusses the epidemiology, risk factors, and pathogenesis of poststroke CIs, current methods for its diagnosis, as well as symptomatic and pathogenetic treatment. The most informative method for the diagnosis of poststroke CIs is neuropsychological examination that should be made in the early poststroke period (if the patient's consciousness is clear. The most common screening tests include mini-mental state examination (the most sensitive to evaluate cognitive dysfunction in Alzheimer type dementias and the Montreal cognitive assessment. Magnetic resonance imaging of the brain, positron emission tomography, cerebrospinal fluid examination, and genetic testing are used to reveal AD at its preclinical stages. Preventive measures include regular physical activity, a balanced diet, and sufficient mental workload. The prevention of stroke and other cardiovascular diseases are also important.The major groups of drugs used to treat AD and vascular CIs are acetylcholinesterase inhibitors and N-methyl-D-aspartate receptor antagonists. It is expedient to use glutamatergic and acetylcholinergic therapy earlier in patients with obvious CIs that are unassociated with emotional problems and disturbance of consciousness. Akatinol memantine is a drug that can be regarded not only as a symptomatic but also pathogenetic agent.

    Kawasaki disease, also known as cutaneous-mucous-glandular mucocutaneous glandular syndrome, is acute systemic vasculitis of small-to-medium calibre arteries, frequently involving coronary arteries, affect almost exceptionally children, with reports concerning cases of Kawasaki syndrome in 20-to-30-year-old adults being extremely rare. The most serious manifestation of Kawasaki disease is coronaritis and formation of coronary artery aneurysms. The dynamics of the formed coronary aneurysms and, consequently, the fate of patients may be different. Thrombosis of an aneurysm in the early period of the disease and stenosing of the affected coronary artery later on present possible complications of Kawasaki disease and potential causes of myocardial infection in young adults. Increased risk of coronary artery thromboses in Kawasaki disease is conditioned by a decrease in velocity of blood flow and its turbulent pattern in the aneurysms, endothelial dysfunction due to currently existing or endured coronaritis and thrombocytosis typical of this pathology. Predisposing factors of coronary artery stenosing are unfavourable haemodynamic conditions appearing at the sites of the "entry" and "exit" of the aneurysm. Described herein are two case reports of myocardial infarction, one of which being a complication of an acute case of Kawasaki disease in a 29-year-old patient, with the second one being a consequence of coronary artery stenosing in a 25-year-old patient who had endured Kawasaki disease in his childhood.

    Stroke and acute myocardial infarction are the leading causes of death and disability in industrialized countries. Multiple interactions exist between the various forms of cardiovascular and cerebrovascular diseases, and risk factors for development of stroke and major cardiovascular events are similar. There is currently no clear link between acute coronary syndrome and stroke, although it has been repeatedly described. In addition, there are currently no clear recommendations for how to proceed in the case of signs of myocardial damage in patients with acute stroke and how to manage the next follow-up.

    By use of noninvasive tests (Doppler segmental pressure study, supraorbital Doppler flow analysis, and segmental plethysmography), coexistent carotid (CTD) or lower extremity peripheral vascular disease (PVD) were diagnosed and correlated with subjective symptoms, coronary risk factors (CRFs), coronary arteriograms (CAGs), cardiac hemodynamics, and infarct size in 121 consecutive patients with documented coronary artery disease (CAD). PVD was found in 16.5%, CTD in 33.1%, and both PVD and CTD in 9.9% of the patients studied; 20% of PVD patients and 47.5% of CTD patients were asymptomatic with respect to coexistent PVD or CTD. There were no significant differences between the presence or absence of PVD or CTD as regards number of CRFs, Killip classification, cardiac hemodynamics, or number of stenotic coronary arteries. However, serum creatine kinase (CK) and CKMB release curves in the PVD group showed significantly higher peak CK and peak CKMB values than those in the PVD(-) group (4096 +/- 5408/282 +/- 263 vs 1706 +/- 1715/179 +/- 186, p less than 0.05) because of the higher prevalence (100%) of multivessel disease on CAG. Investigation of the relationship of CRFs to coexistent PVD revealed that the smoking ratio in men (86.7%) and the hypertension ratio in women (80%) were extremely high in PVD patients, and statistically significant differences between PVD(+) patients and PVD(-) groups were found with respect to the obesity ratio (p less than 0.05) in men and the hypercholesterolemia ratio (p less than 0.05) and obesity ratio (60%, p less than 0.05) in women.(ABSTRACT TRUNCATED AT 250 WORDS)

  19. Role of coronary physiology in the contemporary management of coronary artery disease.

    Coronary artery disease (CAD) remains the leading cause of death worldwide with approximately 1 in 30 patients with stable CAD experiencing death or acute myocardial infarction each year. The presence and extent of resultant myocardial ischaemia has been shown to confer an increased risk of adverse outcomes. Whilst, optimal medical therapy (OMT) forms the cornerstone of the management of patients with stable CAD, a significant number of patients present with ischaemia refractory to OMT. Historically coronary angiography alone has been used to determine coronary lesion severity in both stable and acute settings. It is increasingly clear that this approach fails to accurately identify the haemodynamic significance of lesions; especially those that are visually "intermediate" in severity. Revascularisation based upon angiographic appearances alone may not reduce coronary events above OMT. Technological advances have enabled the measurement of physiological indices including the fractional flow reserve, the index of microcirculatory resistance and the coronary flow reserve. The integration of these parameters into the routine management of patients presenting to the cardiac catheterization laboratory with CAD represents a critical adjunctive tool in the optimal management of these patients by identifying patients that would most benefit from revascularisation and importantly also highlighting patients that would not gain benefit and therefore reducing the likelihood of adverse outcomes associated with coronary revascularisation. Furthermore, these techniques are applicable to a broad range of patients including those with left main stem disease, proximal coronary disease, diabetes mellitus, previous percutaneous coronary intervention and with previous coronary artery bypass grafting. This review will discuss current concepts relevant to coronary physiology assessment, its role in the management of both stable and acute patients and future applications.

    In clinical practice the non-invasive diagnosis of "coronary heart disease" is based on the clinical findings, the detection of ischemia at rest or during exercise, and elevations of cardiac enzymes. However, due to the compensatory enlargement of the vessel diameter at the beginning of plaque growth, the so-called Glagov effect, early stages of plaque development are missed by the angiography. By means of coronary angiography, changes of the coronary arteries become visible only in patients with angiographically recognizable lumen narrowing compared to the reference vessel segment. Thus, early or diffuse stages of atherosclerosis cannot be detected by ECG, stress-tests or coronary angiography. This limitation explains discrepancies, like positive troponin-test and even transmural ischemia, without angiographic visible coronary lumen narrowing. Diagnostic procedures such as intravascular ultrasound, optical coherence tomography, measurements of vasomotion and computed tomography can, in contrast, detect earlier stages of coronary artery disease and thus contribute to clarification in these patients. In addition, plaque rupture and plaque-erosion lead to acute or recurrent microembolism to distal myocardium with subsequent myocardial necrosis. In patients with formerly unexplained cardiovascular events, intravascular ultrasound, optical coherence tomography, and measurements of vasomotion help to understand the underlying pathophysiology. In the report after cardiac catheterization, the term "ruled out coronary heart disease" should be replaced by "No signs of obstructive coronary heart disease" and additional testing should be performed as necessary.

    2008-04-01

    This paper is concerned with changing conceptions of genetic disease. It is based on an analysis of biomedical literature and focuses on the treatment of coronary heart disease (CHD) in four published commentary papers. The aim of this analysis is to explore the ways in which CHD is constructed as genetic and the place of genetic discourses in the wider set of ideas that circulate about the disease. This analysis is then used to consider some of the claims of the geneticisation thesis (Lippman 1991, 1992). The analysis suggests that a genetic vision for understanding and managing CHD has emerged, which has many of the hallmarks of the geneticisation imagined by Lippman. However, a number of alternative and competing models of CHD are also supported within the biomedical discourse. These are related to the different disciplines with a stake in the field of CHD, and their struggles for authority. In conclusion, it is suggested that the geneticisation thesis, as a universal claim, is at odds with the diffuse and distributed nature of biomedical knowledge and practice. Rather than analysing geneticisation in a literal way, it may be more fruitful to see the thesis, itself, as a form of boundary work (Gieryn 1983).

    This study determines whether a mathematical model can be used to assess noninvasively the extent of coronary artery disease (CAD). The model was based on stepwise multivariate discriminant analysis of data obtained in 99 patients from clinical and nonhemodynamic exercise variables, or from radionuclide determination of left ventricular function at rest or during exercise, or both. The extent of CAD was assessed by a scoring system and by the number of diseased vessels. The variables selected by this method (Q-wave infarction, exercise LV ejection fraction, change in systolic blood pressure from rest to exercise, sex and diabetes mellitus) yielded a predictive accuracy of 82% for the identification of patients with extensive CAD (score greater than or equal to 35). Slightly better results were achieved by a subgroup of 77 patients who had adequate exercise end points (exercise heart rate greater than or equal to 120 beats/min, or angina or ST depression during exercise). In these patients, the predictive accuracy was 84%. The model also identified patients with "light" CAD (score less than or equal to 10) with a predictive accuracy of 82%. Thus, noninvasive assessment of the extent of CAD is possible with a stepwise multivariate discriminant analysis of clinical, electrocardiographic and left ventricular function assessed by radionuclide ventriculography at rest and during exercise. The scoring system was superior to the conventional method of classifying patients according to the number of diseased vessels.

    Full Text Available The importance of the comorbidity problem of coronary heart disease and osteoporosis is caused by the rising prevalence, lack of early detection, prevention, severe complications and significant impact on the quality of life of the patients. Aim. In order to compile and submit a current point of view on the pathogenetic relationship between the coronary heart disease and the osteopenic syndrome we reviewed specialized literature. Conclusion. We established that coronary heart disease and osteoporosis have common mechanisms of progression involving a cascade of proinflammatory cytokines, osteoprotegerin, endothelial dysfunction, estrogen, calcium deficiency, the renin-angiotensin-aldosterone and sympathetic nervous system.

    Full Text Available Inflammation is widely considered to be an important contributing factor of the pathophysiology of coronary heart disease (CHD, and the inflammatory cascade is particularly important in the atherosclerotic process. In consideration of the important role that inflammatory processes play in CHD, recent work has been focused on whether biomarkers of inflammation may help to improve risk stratification and identify patient groups who might benefit from particular treatment strategies. Of these biomarkers, C-reactive protein (CRP has emerged as one of the most important novel inflammatory markers. CRP an acute phase protein is synthesized by hepatocytes in response to proinflammatory cytokines, in particular interleukin-6. Many large-scale prospective studies demonstrate that CRP strongly and independently predicts adverse cardiovascular events, including myocardial infarction, ischemic stroke, and sudden cardiac death in individuals both with and without overt CHD. CRP is believed to be both a marker and a mediator of atherosclerosis and CHD. CRP plays a pivotal role in many aspects of atherogenesis including, activation of complement pathway, lipids uptake by macrophage, release of proinflammatory cytokines, induces the expression of tissue factor in monocytes, promotes the endothelial dysfunction and inhibits nitric oxide production. The commercial availability of CRP high sensitive assays has made screening for this marker simple, reliable, and reproducible and can be used as a clinical guide to diagnosis, management, and prognosis of CHD.

  9. Arterial stiffness as a risk factor for coronary artery disease.

    2014-02-01

    Hypertension is a major modifiable risk factor, and clinical trials have demonstrated that successful reduction of elevated blood pressure to target levels translates into decreased risk for the development of coronary artery disease, stroke, heart failure, and renal failure. The arterial system had previously been regarded as a passive conduit for the transportation of arterial blood to peripheral tissues. The physiologic role the arterial system was greatly expanded by the recognition of the central role of the endothelial function in a variety of physiologic processes. The role of arterial function and structure in cardiovascular physiology was expanded with the development of a variety of parameters that evaluate arterial stiffness. Markers of arterial stiffness have been correlated with cardiovascular outcomes, and have been classified as an emerging risk factor that provides prognostic information beyond standard stratification strategies involving hypertension, diabetes, obesity, dyslipidemia and smoking. Multiple epidemiologic studies have correlated markers of arterial stiffness such as pulse-wave velocity, augmentation index and pulse pressure with risk for the development of fatal and nonfatal cardiovascular events. Additionally, measurements of arterial stiffness had clarified the results of clinical trials that demonstrated differing impacts on clinical outcomes, despite similar reductions in blood pressure, as measured by brachial and sphygmomanometry.

    Clinical experience suggests that atherosclerotic disease is common in individuals with coeliac disease, but epidemiological studies have had contradicting findings. To summarise the currently available evidence, we systematically reviewed and analysed observational studies of the association of coeliac disease or dermatitis herpetiformis with coronary heart disease (CHD) or stroke. We searched for studies comparing CHD or stroke outcomes with individuals with and without coeliac disease or dermatitis herpetiformis. Three investigators independently searched electronic databases, identified relevant studies and extracted data. Study-specific results were combined in random-effects meta-analyses, and heterogeneity was quantified using the I(2) statistic and meta-regression. Twenty-one studies were included in our systematic review and 18 in the meta-analyses. For CHD, the pooled hazard ratio for incident disease was 1.05 (95% confidence interval (CI): 0.93, 1.19) and the overall standardised mortality ratio was 1.21 (0.99, 1.49). For stroke and brain haemorrhage, the corresponding estimates were 1.10 (95% CI: 1.00, 1.21) and 1.43 (0.97, 2.10), respectively. There was moderate to considerable heterogeneity among the study-specific estimates. In addition, many estimates were based on small numbers of outcomes and they had limitations in terms of adjustment for potential confounders. Our meta-analyses lend some support to an association between coeliac disease and CHD or cerebrovascular disease, but the evidence base was heterogeneous and had limitations. Our systematic review highlighted a need in this area for adequately powered prospective studies with appropriate adjustment for potentially confounding factors. Copyright © 2015 Elsevier B.V.

    Aim Age and injury cause structural and functional changes in coronary artery smooth muscle cells (caSMCs) that influence the pathogenesis of coronary artery disease. Although paracrine signalling is widely believed to drive phenotypic changes in caSMCs, here we show that developmental origin within the fetal epicardium can have a profound effect as well. Methods and results Fluorescent dye and transgene pulse-labelling techniques in mice revealed that the majority of caSMCs are derived from Wt1+, Gata5-Cre+ cells that migrate before E12.5, whereas a minority of cells are derived from a later-emigrating, Wt1+, Gata5-Cre− population. We functionally evaluated the influence of early emigrating cells on coronary artery development and disease by Gata5-Cre excision of Rbpj, which prevents their contribution to coronary artery smooth muscle cells. Ablation of the Gata5-Cre+ population resulted in coronary arteries consisting solely of Gata5-Cre− caSMCs. These coronary arteries appeared normal into early adulthood; however, by 5–8 months of age, they became progressively fibrotic, lost the adventitial outer elastin layer, were dysfunctional and leaky, and animals showed early mortality. Conclusion Taken together, these data reveal heterogeneity in the fetal epicardium that is linked to coronary artery integrity, and that distortion of the coronaries epicardial origin predisposes to adult onset disease.

  12. Prognostic Value of Circulating Inflammatory Cells in Patients with Stable and Acute Coronary Artery Disease

    Directory of Open Access Journals (Sweden)

    John A. L. Meeuwsen

    2017-07-01

    Full Text Available Atherosclerosis is a lipid driven chronic inflammatory disease underlying the majority of ischemic events such as myocardial infarction or stroke. Clinical management of ischemic events has improved considerably in the past decades. Accordingly, survival rates have increased. Nevertheless, 12% of patients die within 6 months after the initial event. To improve secondary prevention, appropriate risk prediction is key. However, up to date, there is no clinically available routine marker to identify patients at high risk for recurrent cardiovascular events. Due to the central role of inflammation in atherosclerotic lesion progression and destabilization, many studies have focused on the role of circulating inflammatory cells in these processes. This review summarizes the current evidence on the potential of circulating inflammatory cells as biomarkers for recurrent adverse manifestations in acute coronary syndrome and stable coronary artery disease patients.

    The aim of this study was to assess the prognostic value of 64-slice CT angiography (CTA) in patients with known or suspected coronary artery disease (CAD). Sixty-four-slice coronary CTA was performed in 220 patients [mean age 63 {+-} 11 years, 77 (35%) female] with known or suspected CAD. CTA images were analyzed with regard to the presence and number of coronary lesions. Patients were followed-up for the occurrence of the following clinical endpoints: death, nonfatal myocardial infarction, unstable angina, and coronary revascularization. During a mean follow-up of 14 {+-} 4 months, 59 patients (27%) reached at least one of the predefined clinical endpoints. Patients with abnormal coronary arteries on CTA (i.e., presence of coronary plaques) had a 1st-year event rate of 34%, whereas in patients with normal coronary arteries no events occurred (event rate, 0%, p < 0.001). Similarly, obstructive lesions ({>=}50% luminal narrowing) on CTA were associated with a high first-year event rate (59%) compared to patients without stenoses (3%, p < 0.001). The presence of obstructive lesions was a significant independent predictor of an adverse cardiac outcome. Sixty-four-slice CTA predicts cardiac events in patients with known or suspected CAD. Conversely, patients with normal coronary arteries on CTA have an excellent mid-term prognosis. (orig.)

    Background Millions of Americans with suspected coronary artery disease undergo non-invasive cardiac stress testing annually. Downstream procedures and subsequent outcomes among symptomatic patients without known coronary disease referred for stress testing are not well characterized in contemporary community practice. Methods We examined administrative insurance billing data from a national insurance provider from November 2004 through June 2007. After excluding patients with prior cardiac disease or chest pain evaluation, we identified 80,676 people age 40–64 years with outpatient cardiac stress testing within 30 days after an office visit for chest pain. We evaluated rates of invasive coronary angiography, coronary revascularization, and cardiovascular events after stress testing. Results Within 60 days, only 8.8% of stress test patients underwent cardiac catheterization and only 2.7% underwent revascularization; within one year only 0.5% suffered death, myocardial infarction, or stroke. There were marked geographic variations in one-year rates of catheterization (3.8–14.8%) and revascularization (1.2–3.0%) across 20 hospital referral regions. Conclusions In this large national cohort of middle-aged patients without previously coded cardiac diagnosis who were referred for stress testing after outpatient chest pain evaluation, few proceeded to invasive angiography or revascularization, and subsequent cardiovascular events were infrequent.

    We compared the diagnostic performance of aortic calcification volume with that of coronary artery calcification volume at CT in diagnosing obstructive coronary artery disease (OCAD). A total of 308 patients (M: F 141: 167) underwent coronary CT angiography using a 64-slice MDCT. We measured the calcification volume (mm{sup 3}) of coronary artery (CAC), thoracic aorta (TAC), abdominal aorta (AAC), and whole aorta (AC) at unenhanced CT. OCAD was defined as the significant stenosis ({>=} 50%) in any coronary artery at CT angiography. The diagnostic performance for OCAD was evaluated by calculating the area under the receiver operating characteristic (ROC) curve. Among the 308 patients studied, 45 patients were diagnosed with OCAD. The mean volumes of TAC, AAC, AC, and CAC were 518.8 mm{sup 3}, 551.5 mm{sup 3}, 1069.9 mm{sup 3}, 57.6 mm{sup 3} respectively. The areas under the ROC curve of TAC, AAC, AC, and CAC for OCAD were 0.766 (0.694 < 95% confidence interval < 0.838), 0.837 (0.784 < 95% confidence interval < 0.892), 0.814 (0.755 < 95% confidence interval < 0.873), 0.871 (0.812 < 95% confidence interval < 0.930), respectively. The volume of aortic calcification as well as coronary artery calcification is associated with obstructive coronary artery disease.

    Heart disease was an uncommon cause of death in the US at the beginning of the 20th century. By mid-century it had become the commonest cause. After peaking in the mid-1960s, the number of heart disease deaths began a marked decline that has persisted to the present. The increase in heart disease deaths from the early 20th century until the 1960s was due to an increase in the prevalence of coronary atherosclerosis with resultant coronary heart disease, as documented by autopsy studies. This increase was associated with an increase in smoking and dietary changes leading to an increase in serum cholesterol levels. In addition, the ability to diagnose acute myocardial infarction with the aid of the electrocardiogram increased the recognition of coronary heart disease before death. The substantial decrease in coronary heart disease deaths after the mid-1960s is best explained by the decreased incidence, and case fatality rate, of acute myocardial infarction and a decrease in out-of-hospital sudden coronary heart disease deaths. These decreases are very likely explained by a decrease in coronary atherosclerosis due to primary prevention, and a decrease in the progression of nonobstructive coronary atherosclerosis to obstructive coronary heart disease due to efforts of primary and secondary prevention. In addition, more effective treatment of patients hospitalized with acute myocardial infarction has led to a substantial decrease in deaths due to acute myocardial infarction. It is very likely that the 20th century was the only century in which heart disease was the most common cause of death in America.

The article is presented which coroner artery disease and coroner-pulmonary artery fistula was accomplishment committed. Sixty three year-old male patient admitted to the hospital with chest pain. Non-ST myocardial infarction was diagnosed in the examinations. After coroner angiography, it was found coronary artery disease in addition between LAD proximal portion and main pulmonary artery fistula. Fistula repair and coronary bypass were performed successfully under cardiopulmonary bypass. Without hemodynamic problem in intensive care and service follow-up, the patient was discharged from the hospital in the seventh postoperative day. We think that surgical treatment of coronary fistulas in patients with coronary artery lesion is done at the earliest time would enable improvement in mortality and morbidity rates.

    Epidemiological research over the last 50 years has discovered a plethora of biomarkers (including molecules, traits or other diseases) that associate with coronary artery disease (CAD) risk. Even the strongest association detected in such observational research precludes drawing conclusions about the causality underlying the relationship between biomarker and disease. Mendelian randomization (MR) studies can shed light on the causality of associations, i.e whether, on the one hand, the biomarker contributes to the development of disease or, on the other hand, the observed association is confounded by unrecognized exogenous factors or due to reverse causation, i.e. due to the fact that prevalent disease affects the level of the biomarker. However, conclusions from a MR study are based on a number of important assumptions. A prerequisite for such studies is that the genetic variant employed affects significantly the biomarker under investigation but has no effect on other phenotypes that might confound the association between the biomarker and disease. If this biomarker is a true causal risk factor for CAD, genotypes of the variant should associate with CAD risk in the direction predicted by the association of the biomarker with CAD. Given a random distribution of exogenous factors in individuals carrying respective genotypes, groups represented by the genotypes are highly similar except for the biomarker of interest. Thus, the genetic variant converts into an unconfounded surrogate of the respective biomarker. This scenario is nicely exemplified for LDL cholesterol. Almost every genotype found to increase LDL cholesterol level by a sufficient amount has also been found to increase CAD risk. Pending a number of conditions that needed to be fulfilled by the genetic variant under investigation (e.g. no pleiotropic effects) and the experimental set-up of the study, LDL cholesterol can be assumed to act as the functional component that links genotypes and CAD risk and

    Full Text Available OBJECTIVE: Although some investigations have shown a relationship between nonalcoholic fatty liver disease (NAFLD and cardiovascular diseases, there are few studies analyzing the relationship between NAFLD and coronary artery disease (CAD. The aim of this article was to review the relationship between NAFLD and CAD and the methods of diagnosis used to assess such relationship. METHODS: A review was performed using search engines of indexed scientific material, including MEDLINE (by PubMed, Web of Science, IBECS, and LILACS, to identify articles published in Portuguese, English, and Spanish until August, 2012. The studies were eligible if they included the following data: place and year of publication, prevalence and methods used to diagnose NAFLD (ultrasound, computed tomography, nuclear magnetic resonance, or biopsy and CAD (coronary angiography, or computed tomography, and the exclusion of patients due to alcohol consumption greater than 20 g/day. RESULTS: Ten articles were selected, most of which were cross-sectional studies. The studies mostly observed the association between NAFLD and the presence and severity of CAD. CONCLUSION: The analysis of the review showed that evaluating the existence of NAFLD in patients with CAD from its subclinical form up to the symptomatic clinical form is important due to the higher risk of acute myocardial infarction and consequent increase of mortality.

    One of the most important complications of Kawasaki disease is the development of giant coronary aneurysms. Risk factors for their development are still not clear. A retrospective analysis was conducted at the National Institute of Paediatrics in Mexico City, Mexico. It included all patients with a diagnosis of acute Kawasaki disease between August, 1995 and August, 2015. Clinical and laboratory findings, as well as echocardiographic measurements, were recorded. Patients with giant coronary aneurysms (z-score⩾10) were compared with the rest of the patients. A value of pKawasaki disease. Of them, 34 developed giant coronary aneurysms during the acute stage of the disease. In the multivariate analysis, patients younger than 1 year, those with a higher duration of illness at the time of diagnosis, and those who received additional intravenous immunoglobulin showed a significantly higher frequency of giant coronary aneurysms. One of the main factors associated with the development of giant coronary aneurysms was the delay in the diagnosis of Kawasaki disease. This finding highlights the importance of maintaining a high suspicion of the disease, which would enable an early diagnosis and prompt treatment and decrease the risk for developing giant coronary aneurysms.

    Background Studies on selected patients undergoing off-pump versus on-pump coronary artery bypass surgery have produced inconsistent results, especially in patients with multiple coronary artery disease. This study compared the clinical results of on-pump and off-pump coronary bypass surgery in patients with triple-vessel disease.Methods A total of 300 consecutive isolated, multiple coronary artery bypass grafting (CABG) patients were assigned to the off-pump coronary artery bypass (OPCAB, n=150) or CABG with cardiopulmonary bypass (CCABG, n=150) groups. There were no significant differences regarding degree of angina, history of myocardial infarction or diabetes, and presence of left main coronary artery disease between the two groups. Ejection fraction in the OPCAB group before surgery was lower than in the CCABG group (P<0.01). In addition, more patients had a history of stroke and abnormal renal function preoperatively in the OPCAB group(P< 0.01). In OPCAB patients, single deep pericardial stay suture with a sling snared down was used to expose the target vessels, along with a stabilizer and a coronary shunt. A Medi-Stim Butterfly Flowmeter was used to measure blood flow through grafts in both groups.Results No OPCAB patient was converted to the CCABG group. The average numbers of distal anastomoses and the indexes of completeness of revascularization (ICR) were similar in both groups. Postoperative respiratory support time and the volumes of chest tube drainage and of blood transfusions were less in the OPCAB group than in the CCABG group (both P<0.01). The postoperative incidences of pulmonary dysfunction and renal insufficiency were lower in the OPCAB group than in the CCABG group (both P<0.05). There were no significant differences between the two groups in mortality and other causes of morbidity (periopetative myocardial infarction, stroke, atrial fibrillation). Conclusions OPCAB can be applied to patients with triple-vessel coronary artery disease and can

    Objectives To summarize our preliminary experience on off-pump coronary endarterectomy and bypass grafting in patients with diffuse coronary artery disease. Methods Over a 3-year period, 53 patients (41 male) with diffuse coronary artery disease underwent off-pump coronary endarterectomy and bypass grafting at our institution.Patients' age ranged from 55 to 79 years. Prior to surgery, 70% of patients were in CCS angina class 2 (n=5) or 3 (n=32), and nearly half of them (26/53) had history of myocardial infarction. Most patients (n=50) had triple vessel lesions, with left main stem involvement in 9. Their left ventricular ejection fraction ranged from 26% to 65% (mean 52%). At the end of operation, a flow-meter was routinely applied to measure the perfusion flow of each postendarterectomy graft. Results In total, 70 endarterectomies were performed in 53 patients, including 38 in left anterior descending artery (LAD), 8 in circumflex artery and 24 in right coronary artery. Four operations were emergency or urgent in nature. Five patients received on-lay venous patch after endarterectomy in LAD, followed by left internal mammary artery (LIMA) grafting on the patch. The graft conduits included 53 LIMAs and 2 radial arteries,and saphenous veins in others. Mean number of grafts per patient was 3.75. The overall index of completeness of revascularization reached 1.03±0.07. There was no death in this group of patients during their post-operative hospital stay (mean duration = 9 days).Intra-operatively, 63 (90%) out of the 70 grafts after coronary endarterectomy showed satisfactory flow. Two patients had perioperative myocardial infarctions but neither experienced significant hemodynamic deteriations. Conclusions Off-pump coronary endarterectomy with bypass grafting is technically feasible and can be performed safely in patients with diffuse coronary artery disease. This strategy may help to improve the completeness of myocardial revascularization.

  11. Women and Coronary Artery Disease. Part I: Basic Considerations

    Full Text Available Women die of cardiovascular disorders even more than a combination of breast cancer, stroke, chronic obstructive pulmonary disease, and lung cancer. Recent data show that while 1 out of 2.6 women die of coronary artery disease (CAD, only 1 out of 4.6 die from cancer. Whereas some studies show an increase in the age-adjusted mortality of CAD in both women and men, some other studies report an increase in mortality amongst young women. There is a significant decrease in sudden cardiac death in men without significant change in women, and more women die of CAD before their arrival at the emergency room of hospitals than do men. It is, therefore, regrettable that many women and their physicians are not sufficiently aware of the problem and this unawareness is believed to be a major culprit for the existing gender disparities and inaction on the part of women as regards risk modification. What is more, the bulk of our knowledge, preventive measures, diagnostic strategies, and treatment plans are on the basis of studies conducted chiefly in men, when powerful evidence-based gender-specific recommendations call for efforts to enroll more women in order to reach a desirable level of sex representation.Given the significance of CAD assessment in women, it is essential that an acceptable risk score system be devised to estimate the risk of coronary events. The Framingham Risk Score, which has been used for this purpose for a long time, is no longer suitable for women and the Reynolds Risk Score seems to be a more appropriate tool.Finally, from a pathophysiological point of view, endothelial and microvascular dysfunctions are the most salient contributors to the development of CAD in women by comparison with men and they give rise to non-obstructive CAD. Lamentably, most of the relevant studies conducted hitherto have focused predominantly on men; any attempt to redress the balance would be of great value in the endeavors to decrease the risk in women.

    Objective The formation of thrombi at the site of atherosclerotic lesions plays a central role in atherothrombosis. Impaired fibrinolysis may exacerbate pre-existing coronary artery disease and potentiate its evolution. While the fibrinogen plasma level has been strongly associated with the severity of coronary artery disease, its relevance in the evaluation of plasminogen in coronary artery disease patients remains unclear. This study evaluated fibrinogen and plasminogen levels in subjects with coronary artery disease as diagnosed by angiography. Methods This is a cross-sectional study. Blood samples obtained from 17 subjects with angiographically normal coronary arteries (controls), 12 with mild/moderate atheromatosis and 28 with severe atheromatosis were evaluated. Plasma plasminogen and fibrinogen levels were measured by chromogenic and coagulometric methods, respectively. Results Fibrinogen levels were significantly higher in the severe atheromatosis group compared to the other groups(p-value < 0.0001). A significant positive correlation was observed between the severity of coronary artery diseaseand increasing fibrinogen levels (r = 0.50; p-value < 0.0001) and between fibrinogen and plasminogen levels (r =0.46; p-value < 0.0001). There were no significant differences in the plasminogen levels between groups. Conclusion Plasma fibrinogen, but not plasminogen levels were higher in patients with coronary artery disease compared to angiographically normal subjects. The plasma fibrinogen levels also appear to be associated with the severity of the disease. The results of this study provide no evidence of a significant correlation between plasma plasminogen levels and the progress of coronary stenosis in the study population. PMID:23049444

    Nanotechnology holds tremendous potential to advance the current treatment of coronary artery disease. Nanotechnology may assist medical therapies by providing a safe and efficacious delivery platform for a variety of drugs aimed at modulating lipid disorders, decreasing inflammation and angiogenesis within atherosclerotic plaques, and preventing plaque thrombosis. Nanotechnology may improve coronary stent applications by promoting endothelial recovery on a stent surface utilizing bio-mimetic nanofibrous scaffolds, and also by preventing in-stent restenosis using nanoparticle-based delivery of drugs that are decoupled from stents. Additionally, nanotechnology may enhance tissue-engineered graft materials for application in coronary artery bypass grafting by facilitating cellular infiltration and remodeling of a graft matrix.

    Heart rate (HR) lowering by β-blockade was shown to be beneficial after myocardial infarction. In contrast, HR lowering with ivabradine was found to confer no benefits in 2 prospective randomized trials in patients with coronary artery disease. We hypothesized that this inefficacy could be in part related to ivabradine's effect on central (aortic) pressure. Our study included 46 patients with chronic stable coronary artery disease who were randomly allocated to placebo (n=23) or ivabradine (n=23) in a single-blinded fashion for 6 months. Concomitant baseline medication was continued unchanged throughout the study except for β-blockers, which were stopped during the study period. Central blood pressure and stroke volume were measured directly by left heart catheterization at baseline and after 6 months. For the determination of resting HR at baseline and at follow-up, 24-hour ECG monitoring was performed. Patients on ivabradine showed an increase of 11 mm Hg in central systolic pressure from 129±22 mm Hg to 140±26 mm Hg (P=0.02) and in stroke volume by 86±21.8 to 107.2±30.0 mL (P=0.002). In the placebo group, central systolic pressure and stroke volume remained unchanged. Estimates of myocardial oxygen consumption (HR×systolic pressure and time-tension index) remained unchanged with ivabradine.The decrease in HR from baseline to follow-up correlated with the concomitant increase in central systolic pressure (r=-0.41, P=0.009) and in stroke volume (r=-0.61, PHeart Association, Inc.

    We conducted a prospective investigation of the effect of coffee consumption on coronary heart disease in 1130 male medical students who were followed for 19 to 35 years. Changes in coffee consumption and cigarette smoking during follow-up were examined in relation to the incidence of clinically evident coronary disease in comparisons of three measures of coffee intake--base-line intake, average intake, and most recent intake reported before the manifestation of coronary disease. Clinical evidence of coronary disease included myocardial infarction, angina, and sudden cardiac death. In separate analyses for each measure of coffee intake, the relative risks for men drinking five or more cups of coffee per day, as compared with nondrinkers, were approximately 2.80 for all three measures in the univariate analyses (maximum width of 95 percent confidence intervals, 1.27 to 6.51). After adjustment for age, current smoking, hypertension status, and base-line level of serum cholesterol, the estimated relative risk for men drinking five or more cups of coffee per day (using the most recent coffee intake measure), as compared with those drinking none, was 2.49 (maximum width of 95 percent confidence interval, 1.08 to 5.77). The association between coffee and coronary disease was strongest when the time between the reports of coffee intake and the coronary event was shortest. These findings support an independent, dose-responsive association of coffee consumption with clinically evident coronary heart disease, which is consistent with a twofold to threefold elevation in risk among heavy coffee drinkers.

    Introduction: Although studies have shown high diagnostic accuracy of coronary tomography (CT) in detecting coronary artery disease (CAD), data on the prognostic value of this method in patients with no significant coronary obstruction are limited. Objective: To evaluate the value of CT in predicting adverse events in patients with suspected CAD and no significant coronary obstruction. Methods: We prospectively evaluated 440 patients between January 2008 and July 2013 by MDCT, diagnosed with no significant obstruction or no atherosclerotic coronary obstruction with an average follow-up of 33 months. The outcomes evaluated were: cardiac death, myocardial infarction, unstable angina associated with hospitalization or coronary artery bypass grafting. Results: Of the 440 patients studied, 295 (67%) were men with mean age 55.9 ± 12.0 years. Non-significant obstruction was found in 152 (35%) of the patients and there were 49 (11%) outcomes. In the multivariate analysis using the Cox regression model, the predictors of clinical outcomes were non-significant obstruction on CT (hazard ratio 3.51; 95% CI 1.73 - 7.8; p <0.01), age and hypertension. Non-significant obstruction on CT was associated with adverse clinical outcomes and survival analysis showed a significant difference (log-rank 24.6; p <0.01) in predicting these outcomes. Conclusion: The detection of non-significant atherosclerotic obstruction by CT was associated with the presence of adverse events in patients with suspected CAD, which may prove useful in the risk stratification of these patients.

    Estimating cardiovascular disease (CVD) risk is necessary for determining the potential net benefit of primary prevention pharmacotherapy. Risk estimation relying exclusively on traditional CVD risk factors may misclassify risk, resulting in both undertreatment and overtreatment. Coronary artery calcium (CAC) scoring personalizes risk prediction through direct visualization of calcified coronary atherosclerotic plaques and provides improved accuracy for coronary heart disease (CHD) or CVD risk estimation. In this review, we discuss the most recent studies on CAC, which unlike historical studies, focus sharply on clinical application. We describe the MESA CHD risk calculator, a recently developed CAC-based 10-year CHD risk estimator, which can help guide preventive therapy allocation by better identifying both high- and low-risk individuals. In closing, we discuss calcium density, regional distribution of CAC, and extra-coronary calcification, which represent the future of CAC and CVD risk assessment research and may lead to further improvements in risk prediction.

    Full Text Available Abstract Antithrombotic therapy is the cornerstone of the treatment of acute coronary syndromes, but there is now evidence which indicates that by blocking inflammation, thrombosis and thus, acute coronary events, could be lowered. The concept of athero-inflammation emerges as the meeting point of different morbidities; dyslipemia, diabetes, hypertension, obesity, immunity, infection, hyperhomocyteinemia, smoking, etc. usual named as risk factors. Thus, beside specific drugs, earliest treatment, in the stage of inflammation, using anti-inflammatory drugs, should be considered since in patients with increased risk of acute coronary process are likely to have many point of origen throughout the coronary arteries. There are a body of evidences for supporting the potential of anti-inflammatory therapy to the prevention of inflammation and atherosclerosis. COX-2 inhibition may decrease endothelial inflammation reducing monocytes infiltration improving vascular cells function, plaque stability and probably resulting in a decrease of coronary atherothrombotic events. Trials including large numbers of patients in prospective double-blind randomized studies worthwhile to confirm the efficacy of NSAID, mainly, COX-2 inhibitors, together with aspirin in the prevention of coronary events in patients with acute coronary disease.

    Omega-3 polyunsaturated fatty acids are found in fish oil and they have been shown to mitigate the risk of cardiovascular disease. Omega-3 fatty acids are essential fatty acids because they cannot be synthesized de novo and must be consumed from dietary sources such as marine fish. It reduces fatal and nonfatal myocardial infarction, stroke, coronary artery disease, sudden cardiac death, and all-cause mortality. It also has beneficial effects in mortality reduction after a myocardial infarction. Omacor is a highly potent form of Omega-3 fatty acids that lowers plasma triglycerides. In patients with severe hypertriglyceridemia who are refractory to statins, it helps augment triglyceride reduction. Omacor also increases high-density lipoprotein and decreases low-density lipoprotein levels. It is well tolerated with minimal adverse effects and no known interactions causing rhabdomyolysis. In high doses, Omacor has pronounced cardiovascular benefits with improvement of triglycerides and various lipid parameters. Omega-3 fatty acids have also been shown to have beneficial effects on arrhythmias, inflammation, and heart failure. It may also decrease platelet aggregation and induce vasodilation. Omega-3 fatty acids also reduce atherosclerotic plaque formation and stabilize plaques preventing plaque rupture leading to acute coronary syndrome. Moreover, omega-3 fatty acids may have antioxidant properties that improve endothelial function and may contribute to its antiatherosclerotic benefits. In this review, we sought to provide the current literature on the use of omega-3 fatty acids and the potent formulation Omacor in the treatment of coronary artery disease.

    The first evidence that fish oil fatty acids might have a beneficial effect on coronary heart disease came from the discovery that Greenland Eskimos, who have a diet high in n-3 fatty acids, have a lower mortality from coronary heart disease than do Danes and Americans. Long-chain polyunsaturated fatty acids are essential in our diets and can be classified in 2 groups: n-6 fatty acids found in plant seeds and n-3 fatty acids found in marine vertebrates. Further evidence of n-3 benefits to human health include a 1989 study demonstrating a 29% reduction in fatal cardiac arrhythmias among subjects with a recent myocardial infarction who had been advised to consume fish oil. The GISSI-Prevenzione Trial found a significant reduction in relative reduction of death, cardiac death, nonfatal myocardial infarction, and stroke in subjects consuming n-3 fatty acids. In a recent study, subjects with implanted cardiac defibrillators (ICDs) at high risk for fatal ventricular arrhythmias were randomly assigned to four 1-g capsules of either an ethyl ester concentrate of n-3 fatty acids or olive oil daily for 12 mo. Subjects receiving n-3 who thus had significantly higher levels of eicosapentaenoic acid and docosahexaenoic acid in their red blood cell membranes showed a longer time to first ICD events and had a significantly lower relative risk of having an ICD event or probable event (P = 0.033). These studies demonstrate that fish oil fatty acids have beneficial effects on coronary heart disease.

    Using linear regression, the authors demonstrated a strong association between State-specific coronary heart disease mortality rates and State prevalence of sedentary lifestyle (r2 = 0.34; P = 0.0002) that remained significant after controlling for the prevalence of diagnosed hypertension, smoking, and overweight among the State's population. This ecologic analysis suggests that sedentary lifestyle may explain State variation in coronary heart disease mortality and reinforces the need to include physical activity promotion as a part of programs in the States to prevent heart disease.

    The prevalence of coronary artery disease increases with age. Its clinical presentation is even less typical and its prognosis even more severe that it occurs in frail subjects with several co-morbidities. These atypical symptoms are often associated with a delayed diagnosis and therapy. The presence of comorbidities requires a comprehensive geriatric assessment to detect the existence of "frailty". Evidence based medicine available for coronary artery disease is based on studies that involve very few subjects over 80 years and recommendations are extrapolated from data based on evidence obtained in younger populations. Basically the strategy of treatments of coronary artery disease in octogenarians remains identical to the youngest subject. However, epidemiological studies indicate an under-prescription of recommended drugs whereas this older population is likely to derive the greatest benefit because of its elevated cardiovascular risk. Cautions for use of cardio-vascular therapies are necessary in octogenarian people because of comorbidities and pharmacokinetic and pharmacodynamic changes related to aging. Globally, the therapeutic strategy of coronary artery disease should be based not on the age but on an individual analysis that takes into account the severity of coronary artery disease, the existence of comorbidities, the iatrogenic risk, the expectancy and the quality of life of the patient.

    The heterogeneity and complexity of coronary vasculature (structure) and myocardial flow (function) have fractal-like characteristics and can be described by scaling laws with remarkable simplicity. In contrast with allometric (interspecific) scaling law, intraspecific scaling laws describe the design rules of vascular trees within a species. This paper provides an overview of intraspecific scaling laws of vascular trees and the physiological and clinical implications thereof. The significance and shortcomings of these scaling laws are discussed in relation to diffuse coronary artery disease, Glagov's positive remodeling in early stages of coronary atherosclerosis, treatment guidelines of complex bifurcation lesions, and for estimation of outlet resistance values for computation of blood flow in epicardial coronary arteries. Finally, we summarize the highlights of scaling relations and suggest some future directions.

    Background: Because of growing body of interest on the association between fibrosing idiopathic interstitial pneumonias (f-IIP) and ischaemic heart disease, we initiated this prospective study to evaluate the prevalence of asymptomatic coronary artery disease (CAD) in patients with f-IIP. Methods: Forty-two patients with f-IIP underwent noninvasive screening for CAD that included (a) a chest CT examination enabling calculation of the coronary artery calcium (CAC) score, then depiction of coronary artery stenosis; and (b) stress myocardial perfusion scintigraphy (MPS). Patients with significant coronary abnormalities, defined by a CAC score >400 or coronary artery stenosis >50% at CT and/or perfusion defect >5% at MPS, were referred to the cardiologist. Coronary angiography was indicated in presence of a perfusion defect >10% at MPS or significant left main or proximal left anterior descending stenosis whatever MPS findings. Results: Combining CT and MPS, significant abnormalities were detected in 32/42 patients (76%). The cardiologist: (a) did not consider further investigation in 21 patients (CT abnormalities but no ischaemia at MPS: 12/21; false-positive findings at MPS: 3/21; poor respiratory condition: 6/21); (b) proceeded to coronary angiography in 11 patients which confirmed significant stenoses in 5 patients (5/42; 12%). In the worst-case-scenario (i.e., inclusion of 6 patients with significant coronary artery abnormalities who were not investigated due to poor respiratory condition), the prevalence of CAD reached 26% (11/42). Conclusion: In the studied population of patients with f-IIP, asymptomatic CAD ranged between 12% and 26%.

    Full Text Available At present time, the death rate from cardiovascular disease occupies leading position in the structure of total mortality worldwide. The opportunity to conduct non-invasive studies of the coronary arteries has appeared through the development and implementation of multislice computed tomography (MSCT into medical practice, which carry 64 or more sections. Aim. The purpose of this research is the identification of diagnostic capabilities of 64-slice MSCT in the verification of the severity of coronary artery lesions in patients with proven coronary artery disease. Methods and results. The study has been conducted on a 64-slice CT scanner Optima 660 (GE, USA. The degree of stenosis and calcification of the coronary arteries and also central hemodynamics have been studied. The analysis of survey results of 65 patients with coronary heart disease (30.8% of patients had a history of myocardial infarction has been carried out. The average age of patients in observation group was 60.2 ± 10.56 years. Male patients were dominated (75.4%. According to the 64-slice MSCT it has been found that coronary artery stenosis occurs ≥ 50% in 90.0% of patients with myocardial infarction, and in 32.5% of patients with symptomatic coronary artery disease. Conclusion. Therefore, MSCT has sufficient specificity in the diagnosis of occlusive and stenotic lesions of the coronary arteries, and can be used for screening patients with suspected coronary artery disease.

    Rheumatoid arthritis (RA), periodontal disease (PD), and coronary artery disease (CAD) are common chronic inflammatory diseases. RA is associated with accelerated vascular risk resulting in an increased prevalence of CAD with attendant early mortality and excess morbidity. RA and PD have a common pathobiology. Accordingly, the aim of this study was to evaluate the association between RA, PD, and CAD and the influence of systemic inflammatory factors. A total of 100 active RA patients of which 50 had established CAD and 50 had no CAD were assessed for PD. All subjects underwent a clinical, cardiac, dental, laboratory, and radiological evaluation. Blood samples were obtained, and the level of high sensitivity C-reactive protein (hs-CRP), total white blood counts (WBC), erythrocyte sedimentation rate (ESR), fibrinogen and tumor necrosis factor (TNF) alpha, total cholesterol (TC), and high density lipoprotein (HDL) were assayed. The findings of this study demonstrated an association between RA, PD, and CAD. The RA patients with CAD had significantly more PD than RA patients without CAD. The inflammatory markers, hsCRP, ESR, WBC, fibrinogen, and TNF-alpha, were raised in all patients but were significantly higher in RA patients with CAD who also had PD. HDL levels were lower in RA patients with CAD when compared to RA patients without CAD. Evidence from this study shows an association between RA, PD, CAD, and systemic levels of the inflammatory mediators. The implication is that inflammation may be the central link between the chronic inflammatory, autoimmune disorders, and atherosclerosis.

    Accelerated coronary atherosclerosis in patients with Kawasaki disease, in conjunction with coronary artery aneurysm and stenosis that characterise this disease, are potential risk factors for developing coronary artery disease in young adults. We aimed to determine the prevalence and predictors of coronary artery disease in adult patients with Kawasaki disease. All patients aged 18-55 years of age diagnosed with Kawasaki disease were sampled from Nationwide Inpatient Sample database using International Classification of Diseases 9th revision (ICD 9 code 446.1) from 2009 to 2010. Demographics, prevalence of coronary artery disease, and other traditional risk factors in adult patients with Kawasaki disease were analysed using ICD 9 codes. The prevalence of Kawasaki disease among adults was 0.0005% (n=215) of all in-hospital admissions in United States. The mean age was 27.3 years with women (27.6 years) older than men (27.1 years). Traditional risk factors were hypertension (21%), hyperlipidaemia (15.6%), diabetes (11.5%), tobacco use (8.8%), and obesity (8.8%), with no significant difference between men and women. Coronary artery disease (32.4%), however, was more prevalent in men (44.7%) than in women (12.1%; p=0.03). In multivariate regression analysis, after adjusting for demographics and traditional risk factors, hypertension (OR=13.2, p=0.03) was an independent risk factor of coronary artery disease. There was increased preponderance of coronary artery disease in men with Kawasaki disease. On multivariate analysis, hypertension was found to be the only independent predictor of coronary artery disease in this population after adjusting for other risk factors.

    Full Text Available BACKGROUND Heart disease is a growing problem, particularly in developing countries. India has quoted to have 12.2% and 12% prevalence of coronary artery disease and rheumatic valvular heart disease respectively. Some older reports suggest that rheumatic fever, in addition to producing specific injuries to small coronary arterial branches may accelerate the development of coronary atherosclerosis. AIM To assess the prevalence of Coronary Artery disease in patients with Valvular Heart disease in some selected hospitals of Guwahati, Assam. SETTING AND DESIGN It was conducted in Gauhati Medical College and Hospital and Hayat Hospital, Guwahati. Explorative approach, survey design was selected for the study. MATERIALS AND METHODS Purposive sampling technique was used to select 126 patients who were diagnosed with valvular heart disease. Data was collected through a self-structured interview scheduled on prevalence of coronary artery disease. RESULTS Of the total 126 patients of valvular heart disease, 108 (85.71% cases were rheumatic valvular heart disease and 18 (14.29% were non-rheumatic valvular heart disease. Majority (56.34% of cases with CAD and RHD were in the range of 45 to 54 years. The prevalence of typical angina was significantly high among men (41.18%. Most of the rheumatic patients (72.22% did not complain about angina. Diabetes mellitus, hypertension and dyslipidaemia are significantly high among non-rheumatic group and Coronary artery disease group. In our study, the overall prevalence of significant coronary artery disease in patients with valvular heart disease was 14.28%. CONCLUSION Coronary artery disease prevalence is very high in this part of the country. Health professionals should actively participate in health promotion activities, apply the findings of the study to identify high risk individuals and prevent the occurrence of coronary artery disease.

    Full Text Available Coronary atherothrombotic diseases such as coronary artery disease, peripheral vascular disease, cerebrovascular disease, and heart failure are the serious concerns of the thrombus formed in blood vessels. Anticoagulant and antiplatelet drugs are the cornerstones of the management of these diseases. To prevent the recurrence of these diseases, double antiplatelet drugs such as aspirin and clopidogrel has been the standard management in most hospitals. However, aspirin resistance and clopidogrel inefficient effects due to noncompliance with double drugs regimen can cause a sinister effect on patients. Medicinal plants serve as a greater resource for new medication and their potential currently became a topic of interest to the researchers all over the world. Traditionally, certain herbs have been used as a treatment for heart diseases but have been investigated for their antiplatelet properties. This current review explained few traditional antithrombotic herbals and their antiplatelet properties in vitro and in vivo and this is to be deeply discussed in further research.

    Background: Although CT coronary angiography (CTCA) and MR coronary angiography (MRCA) are increasingly used in patients with Kawasaki disease, comparison of coronary artery assessability and diagnostic performance between the two imaging modalities has been rarely performed. Purpose: To investigate which imaging modality, CTCA or MRCA, is better for evaluating coronary artery abnormalities in patients with Kawasaki disease. Material and Methods: Between 2003 and 2011, 56 patients (38 boys/men; age range, 1-24 years) with Kawasaki disease underwent CTCA or MRCA (group A). Of these, 17 underwent both CTCA and MRCA (group B). Visibility of 11 coronary arterial segments in each patient was graded on a four-point scale. Coronary artery aneurysm, stenosis, and occlusion were evaluated by CTCA and MRCA, based on a reference standard obtained from cardiac catheterization, echocardiography, follow-up CTCA and MRCA, and clinical history. Coronary artery assessability and diagnostic performance were compared between CTCA and MRCA. Results: In per-segment analysis, more segments were assessable on CTCA than on MRCA in both groups. In per-patient analysis of group B, no significant difference in the assessability was found between CTCA (95.0%, 128.3/135 segments) and MRCA (92.4%, 124.8/135 segments) (P > 0.05). Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of CTCA vs. MRCA were 93.1% vs. 77.9% (P < 0.001), 99.2% vs. 99.7% (P = 0.65), 96.8% vs. 98.7% (P = 0.65), 98.2% vs. 94.1% (P < 0.001), and 98.0% vs. 94.9% (P = 0.008), respectively, in group A, and 91.8% vs. 70.4% (P < 0.001), 99.5% vs. 99.5% (P = 1.000), 98.5% vs. 98.0% (P = 1.000), 97.2% vs. 91.1% (P = 0.006), and 97.6% vs. 92.3% (P = 0.004), respectively, in group B. Conclusion: Although CTCA and MRCA show comparable assessability in per-patient analysis, CTCA shows higher diagnostic performance than MRCA for evaluating coronary artery abnormalities in patients with Kawasaki

    Aspiration risk from dysphagia increases with central and peripheral neurologic disease. Stroke, microvascular ischemic disease, a spectrum of neurodegenerative diseases, and advancing dementia all have unique aspects. However, there are distinct commonalities in this population. Increasing nutritional requirements to stave off oropharyngeal muscular atrophy and a sedentary lifestyle further tax the patient's abilities to safely swallow. This article reviews stroke, muscular dystrophy, myasthenia gravis, multiple sclerosis, amyotrophic lateral sclerosis, Parkinson's disease, and advanced dementia. Approaches to screening and evaluation, recognizing sentinel indicators of decline that increase aspiration risk, and options for managing global laryngeal dysfunction are also presented.

    The aim of this study was to determine the effect of statins and hormone therapy on submaximal exercise-induced coronary artery blood flow in postmenopausal women without a history of coronary artery disease. Hormone therapy or statin therapy in early postmenopausal women without coronary artery disease has been shown to enhance arterial endothelial function; we hypothesized that these agents would improve submaximal exercise-induced coronary artery blood flow. Sixty-four postmenopausal women, aged 50 to 65 years without documented coronary artery disease, were randomized in a double-blind, crossover fashion to receive 8 weeks of hormone therapy versus placebo, with or without 80 mg/day of atorvastatin. Before receipt of any therapy and after each treatment period, each woman underwent measures of coronary artery blood flow at rest and stress. The combination of hormone therapy and atorvastatin increased submaximal exercise-induced coronary artery blood flow (P = 0.04). In the subgroups of women compliant with treatment, resting coronary artery blood flow increased in those receiving hormone therapy (P = 0.03) or statin therapy (P = 0.02). In postmenopausal women aged 50 to 65 years without documented coronary artery disease, resting and submaximal exercise-induced coronary artery blood flow improves after receipt of high-dose atorvastatin and conjugated estrogens therapy.

    Enhanced survival following acute myocardial infarction and the declining prevalence of hypertension and valvular heart disease as contributors to incident heart failure (HF) have fueled the emergence of coronary artery disease (CAD) as the primary risk factor for HF development. Despite the acknowledged role of CAD in the development of HF, the role of coronary revascularization in reducing HF-associated morbidity and mortality remains controversial. The authors review key features of the epidemiology and pathophysiology of CAD in patients with HF as well as the emerging data from recent clinical trials that inform the modern approach to management.

    Full Text Available Abstract Background Several lines of evidence support a role for CCL2 (monocyte chemotactic protein-1 and its receptor CCR2 in the development of atherosclerosis. The aim of the present study was to determine the association of the CCR2 Val64Ile polymorphism with the development of coronary artery disease in the WOSCOPS study sample set. Findings A total of 443 cases and 1003 controls from the West of Scotland Coronary Prevention Study (WOSCOPS were genotyped for the Val64Ile polymorphism in the CCR2 gene. Genotype frequencies were compared between cases and controls. The CCR2 Val64Ile polymorphism was found not to be associated with coronary events in this study population (odds ratio 1.15, 95% CI 0.82-1.61, p = 0.41. Conclusions This case-control study does not support an association of the CCR2 Val64Ile polymorphism with coronary artery disease in the WOSCOPS sample set and does not confirm a possible protective role for CCR2 Val64Ile in the development of coronary artery disease.

    Cogan's syndrome (CS) is a rare inflammatory disorder characterized by interstitial keratitis and vestibuloauditory abnormalities often associated with various systemic manifestations. Involvement of cardiovascular system resembling systemic vasculitis may lead to severe complications and death. The present report describes a case of a female patient with atypical Cogan's syndrome presented with systemic manifestations and severe coronary and femoral artery stenosis.Despite the clinical improvement after glucocorticoids and cyclophosphamide, the patient required double aortocoronal bypass grafting one year letter. During three years follow-up, she was in stable condition, without stenocardial symptoms and claudication and her inflammatory parameters remain normal. This case highlights the rare involvement of coronary arteries without associated large-vessel vasculitis of the aortic arch in CS.

  11. Modern antiplatelet agents in coronary artery disease.

    2012-10-01

    Dual antiplatelet therapy is well recognized in the prevention of thrombotic complications of acute coronary syndrome and percutaneous coronary interventions. Despite clinical benefits of aspirin and clopidogrel therapy, a number of limitations curtail their efficacy: slow onset of action, variability in platelet inhibitory response and potential drug-drug interactions. Furthermore, the single platelet-activation pathway targeted by these agents allows continued platelet activation via other pathways, ensuring incomplete protection against ischemic events, thus, underscoring the need for alternate antiplatelet treatment strategies. A number of novel antiplatelet agents are currently in advance development and many have established superior effects on platelet inhibition, clinical outcomes and safety profile than clopidogrel in high-risk patients. The aim of this review is to provide an overview of the current status of P2Y12 receptor inhibition and PAR-1 antagonists in determining a future strategy for individualized antiplatelet therapy.

    This study aimed to investigate the correlation between coronary artery stenosis and Mimecan expression in patients with coronary heart disease (CHD). Seventy eight patients with CHD and 80 controls without vascular lesions were recruited into present study. CHD patients were divided into one-vessel CHD subgroup, 2-vessel CHD subgroup and multivessel CHD subgroup. ELISA was performed to detect the expressions of serum Mimecan and nuclear factor kappaB (NF-κB). When compared with control group, the expressions of serum mimecan gene and NF-κB significantly increased in CHD groups (P coronary lesions (rmimecan=0.79, rNF-κB=0.83, P < 0.05). Increased expressions of serum mimecan and NF-κB in CHD patients are related to cardiac insufficiency, which may be ascribed to the binding of NF-κB to mimecan gene.

  13. Preventing clinically evident coronary heart disease in the postmenopausal woman.

    2004-01-01

    This review summarizes data on the prevalent coronary heart disease risk factors of postmenopausal women and the pharmacologic and nonpharmacologic therapies available for preventing or treating them. Medline searches from 1966 on were used to identify manuscripts for coronary heart disease risk factor information, lipid levels as predictors of cardiovascular disease in women, non-pharmacologic therapies, side effects of statins, and lipid-lowering trials that included women and had myocardial infarction or coronary heart disease death as endpoints. Dyslipidemias that occur with menopause are particularly atherogenic and tend to cluster with other metabolic and nonmetabolic risk factors. Estrogen therapy, with or without progestogen, can no longer be recommended for primary or secondary prevention of cardiovascular disease in postmenopausal women. Statins have been effective in reducing cardiovascular-related morbidity and mortality and should be first-line therapy for lipid-lowering. A considerable number of women look to obstetricians-gynecologists for primary care. For postmenopausal women especially, primary care must include management of risk factors for coronary heart disease. Estrogen or estrogen plus progestin should be used only for symptomatic hot flashes and at the lowest dose possible. Statins should be first-line therapy in preventive strategies for lipid-lowering.

    To reduce the number of invasive X-ray coronary angiography (XCA) in patients with coronary arterial lesions (CAL) due to Kawasaki disease, we evaluated the efficacy of noninvasive magnetic resonance coronary angiography (MRCA). We preformed MRCA on 30 patients with Kawasaki disease (age 4 months to 37 years; medium 9 years) by SIEMENS MAGNETOM Symphony 1.5 T. MRCA with free respiration using navigator echo 3D fast low angle shot (3D-FLASH) was performed on 10 young children. Evaluation of MRCA was based on the findings of 2D echo cardiogram (30 patients) and XCA (14 patients). All 17 aneurysms (100%) were detected by MRCA; four out of five dilatations were detected by MRCA (80%), but a slight dilatation was not detected (i.e., appeared to be a normal coronary artery). We observed seven stenoses (100%) that were detected on XCA and one new stenosis on MRCA; both of two aortocoronary bypass graphs (one in each of two patients; 100%) were observed to be patent. These results demonstrated that MRCA was highly beneficial, first for detecting CAL after the acute phase even in young infants, second for reducing the number of XCA examination times for following up CAL, and third for screening of CAL in adults with a history of Kawasaki disease.

    Cardiovascular disease (including coronary artery disease and myocardial infarction) is one of the leading causes of death in Europe, and is influenced by both environmental and genetic factors. With the recent advances in genomic tools and technologies there is potential to predict and diagnose heart disease using molecular data from analysis of blood cells. We analyzed gene expression data from blood samples taken from normal people (n = 21), non-significant coronary artery disease (n = 93), patients with unstable angina (n = 16), stable coronary artery disease (n = 14) and myocardial infarction (MI; n = 207). We used a feature selection approach to identify a set of gene expression variables which successfully differentiate different cardiovascular diseases. The initial features were discovered by fitting a linear model for each probe set across all arrays of normal individuals and patients with myocardial infarction. Three different feature optimisation algorithms were devised which identified two discriminating sets of genes, one using MI and normal controls (total genes = 6) and another one using MI and unstable angina patients (total genes = 7). In all our classification approaches we used a non-parametric k-nearest neighbour (KNN) classification method (k = 3). The results proved the diagnostic robustness of the final feature sets in discriminating patients with myocardial infarction from healthy controls. Interestingly it also showed efficacy in discriminating myocardial infarction patients from patients with clinical symptoms of cardiac ischemia but no myocardial necrosis or stable coronary artery disease, despite the influence of batch effects and different microarray gene chips and platforms.

    AIMS: Lower extremity peripheral artery disease (PAD) has been proposed as a 'coronary heart disease (CHD) risk equivalent'. We aimed to examine whether PAD confers similar risk for mortality as incident myocardial infarction (MI) and whether risk differs by gender. METHODS: Using nationwide Danish...... the other groups. During follow up (median 1051 d, IQR 384-1938), we found that MI-alone patients had greater risk of adverse outcomes in the acute setting (first 90 d); however, the PAD-only and PAD + MI groups had higher long-term mortality at 7 years than those with MI alone (47.8 and 60.4 vs. 36.......62-1.80, respectively), and composite of death, MI, and ischaemic stroke, 95% CI HR, 1.38, 95% CI 1.36-1.42; and HR 1.68, 95% CI 1.61-1.75, respectively).

    To elucidate knowledge of coronary artery disease (CAD) risks factors and coronary intervention in adult students of Karachi East. To calculate the mean knowledge score about CAD risk factors among them. A multi center crossectional study was conducted in Universities and colleges of Karachi East from April-September 2005. Questionnaires were distributed to 200 adult students of different non-medical universities and colleges. The questionnaire contained assessment of knowledge of risk factors on CAD and awareness about coronary angiography. Those belonging to medical colleges and universities were excluded from the study. Knowledge was assessed as a continuous variable. Risk factors for CAD were taken as categorical variables The mean age of students was 20 yrs +/- 2.2 years and 62% were females. The mean score of knowledge about risk factors of CAD was 11.47 +/- 2.37. Sixty percent students thought that heart diseases are the number one cause of death in our population. Twenty five percent students graded smoking as the top most risk factor for CAD. Twenty five percent students refused to quit smoking for CAD prevention. Forty eight percent students correctly defined coronary angiography. Eighty five percent students thought that cost is the major hindrance in getting timely treatment. Knowledge of fifty percent students was based on personal and family experience of heart disease. Students graded smoking as the topmost risk factor for CAD and cost as the major hindrance in getting timely treatment for heart disease. Only half of the students were aware about coronary angiography. The mean knowledge score among them was above the median score but not up to the mark.

    Atherosclerosis is characterized by chronic inflammation involving autoimmune components. The degree of inflammatory activity, as detectable both within the atherosclerotic plaque and in the circulation, is associated with plaque destabilization and atherothrombotic complications. Endogenous glucocorticoids are modulators of innate and acquired immune responses, and as such play a key role in the reciprocal interaction between neuroendocrine and immune systems. Abnormalities in hypothalamic-pituitary-adrenal axis (HPA) function have been described in several chronic inflammatory disorders, and evidence has emerged lately that HPA dysfunction may be implicated also in the pathogenesis of coronary artery disease. This review is an outline of knowledge gained so far by previous studies of glucocorticoids in coronary atherosclerosis and myocardial infarction. The results consistently point towards a dysregulated cortisol secretion that may involve a failure to contain inflammatory activity. A dysfunctional HPA axis and its possible implications for coronary artery disease progress, including the hypothetical link between stress and inflammation, are discussed.

    The Rome Project of Coronary Heart Disease Prevention (PPCC) is a primary prevention trial of coronary heart disease; it represents the Italian section of the WHO European Multifactor Preventive Trial of CHD. The study has been carried out in 4 working groups of male subjects aged 40-59 years at entry, two groups (a total of 3,131 men) being assigned to treatment and the other two (a total of 2,896 men) to control, with a 6-year follow-up. The preventive intervention aimed at reducing or modifying: mean levels of serum cholesterol (generally through dietary prescriptions and, in a smaller number of subjects, with drug treatment), smoking habits (subjects were advised to reduce or stop smoking); overweight (by means of diet); sedentary life-style (with increased physical activity). The intervention program has also involved other factors such as high levels of serum triglycerides, blood glucose and serum uric acid. The treatment was carried out through individual sessions on about one third of subjects belonging to the upper part of an estimated coronary risk score, while mass education was administered to the remaining two thirds. No intervention at all was offered to the control groups. Changes in the levels of risk factors were measured through periodical examinations of the whole population enrolled in the trial. Monitoring of both fatal and non fatal morbid events provided data on mortality and incidence trends. Over the 6 years of follow-up, the mean reduction in the mean levels of the main coronary risk factors in treated groups, as compared to controls, was as follows: serum cholesterol: 4.8%; systolic blood pressure: 4.6%; number of cigarettes per day: 8.7%; body weight: 2.4%; estimated coronary risk: 38.9%. At the end of the 6 years of observation, mortality for all causes was lower by 6.0% to 10.7% in treated groups than in controls; mortality for coronary heart disease was also lower (by 26.8% to 30.2%), as well as the incidence of fatal plus non

    Objective To compare graft patency in off-pump and conventional coronary artery bypass grafting by using the transit time flow meter in the treatment of triple vessel coronary artery disease. Methods Between June 2000 and April 2001, 60 patients with triple vessel coronary artery disease underwent coronary artery bypass grafting. They were divided into two groups: off-pump and conventional coronary artery bypass. All completed grafts were tested intraoperatively using Transit Time Flow Measurement (TTFM). Preoperative and postoperative variables of the two groups were also compared. Results There were no significant differences in sex, age, weight, acute or remote myocardial infarction, hypertension, diabetes and type of bypass grafts between the two groups. The number of bypass grafts and the assisted respiratory time of the off-pump coronary artery bypass grafting (OPCAB) group were significantly less than those of the conventional coronary artery bypass grafting (CCABG) group. The flow and pulsatile index (PI) of the left anterior descending artery bypass grafts and the right coronary artery bypass grafts were not significantly different between the OPCAB and CCABG groups. The flow of OM in the CCABG group with the multiple anastomosis site of sequential grafts was higher than that in the OPCAB group. Diffused narrow coronary artery bypass grafts in both groups had less flow.Conclusion No signficant differences in graft patency were observed in patients with triple vessel coronary artery disease who had undergone OPCAB or CCABG.

    Kimura disease (KD) is an immune-mediated chronic inflammatory disease of unknown etiology. KD has many complications associated with hypereosinophilia, including various forms of allergic reactions and eosinophilic lung disease. Additionally, hypereosinophilia is associated with hypercoagulability, which may lead to thromboembolic events. A 36-year-old man with KD presented with acute limb ischemia and coronary artery occlusion. He underwent thrombectomy, partial endarterectomy of both popliteal arteries, and coronary artery stent insertion. KD is a systemic disease that affects many organs and presents with thromboembolism and vasculitis. In a patient with KD, physicians should evaluate the vascular system, including the coronary arteries. PMID:28382271

    Full Text Available Abstract Background More than a million diagnostic cardiac catheterizations are performed annually in the US for evaluation of coronary artery anatomy and the presence of atherosclerosis. Nearly half of these patients have no significant coronary lesions or do not require mechanical or surgical revascularization. Consequently, the ability to rule out clinically significant coronary artery disease (CAD using low cost, low risk tests of serum biomarkers in even a small percentage of patients with normal coronary arteries could be highly beneficial. Methods Serum from 359 symptomatic subjects referred for catheterization was interrogated for proteins involved in atherogenesis, atherosclerosis, and plaque vulnerability. Coronary angiography classified 150 patients without flow-limiting CAD who did not require percutaneous intervention (PCI while 209 required coronary revascularization (stents, angioplasty, or coronary artery bypass graft surgery. Continuous variables were compared across the two patient groups for each analyte including calculation of false discovery rate (FDR ≤ 1% and Q value (P value for statistical significance adjusted to ≤ 0.01. Results Significant differences were detected in circulating proteins from patients requiring revascularization including increased apolipoprotein B100 (APO-B100, C-reactive protein (CRP, fibrinogen, vascular cell adhesion molecule 1 (VCAM-1, myeloperoxidase (MPO, resistin, osteopontin, interleukin (IL-1β, IL-6, IL-10 and N-terminal fragment protein precursor brain natriuretic peptide (NT-pBNP and decreased apolipoprotein A1 (APO-A1.

    Background Prediction of severity or complexity of coronary artery disease (CAD) is valuable owing to increased risk for cardiovascular events. Although the association between total coronary artery calcium (CAC) score and severity of CAD, Gensini score was not used, it has been previously demonstrated. There is no information about the association between total CAC score and complexity of CAD. Objectives To investigate the association between severity or complexity of coronary artery disease (CAD) assessed by Gensini score and SYNTAX score (SS), respectively, and coronary artery calcium (CAC) score, which is a noninvasive method for CAD evaluation in symptomatic patients with accompanying significant CAD. Methods Two-hundred-fourteen patients were enrolled. Total CAC score was obtained before angiography. Severity and complexity of CAD was assessed by Gensini score and SS, respectively. Associations between clinical and angiographic parameters and total CAC score were analyzed. Results Median total CAC score was 192 (23.0-729.8), and this was positively correlated with both Gensini score (r: 0.299, p 809 for SS >32 (high SS tertile). Conclusion In symptomatic patients with accompanying significant CAD, total CAC score was independently associated with SS and patients with SS >32 may be detected through high Agatston score.

    Aim: To evaluate the prevalence of coronary artery disease (CAD) in relation to risk of coronary heart disease (CHD) and assess plaque characteristics from coronary computed tomography (CT) angiography in asymptomatic and symptomatic patients. Materials and methods: Three hundred and ninety consecutive patients [asymptomatic group, n = 138; symptomatic group (atypical or non-anginal chest pain), n = 252] were retrospectively enrolled. They were subsequently classified into three CHD risk categories, based on the National Cholesterol Education Program guidelines, and 10 year risks of coronary events were calculated using Framingham risk score. CT was evaluated for stenosis, plaque composition, and coronary calcium scores. Results: CAD was observed in 42% of the asymptomatic group and 62% of the symptomatic group. In the former, the prevalence of CAD in low-, moderate- and high-risk subgroups was 21.4, 47.4 and 65%, respectively, and was 33.3, 74.4, and 72.4% in the symptomatic group. Framingham 10-year risks of coronary events were significantly higher in patients with CAD than in normal participants, and receiver operating characteristics curves showed that discriminatory power was poor in the asymptomatic group and symptomatic men, and good in symptomatic women. Of the participants in the asymptomatic group, 12% exhibited only non-calcified plaques and of the symptomatic group, 7% exhibited only non-calcified plaques. The coronary calcium score was significantly higher for significant stenosis than for non-significant stenosis in both groups. Conclusions: The prevalence of CAD was not negligible even in subgroups with low-to-moderate CHD risk. Additionally, the Framingham risk score was effective for predicting CAD only in symptomatic women. Coronary calcium scores correlated with significant stenosis; however, a sizeable percentage of both groups had only non-calcified plaques.

    To compare the coronary atherosclerotic burden in patients with and without type-2 diabetes using CT Coronary Angiography (CTCA). 147 diabetic (mean age: 65 {+-} 10 years; male: 89) and 979 nondiabetic patients (mean age: 61 {+-} 13 years; male: 567) without a history of coronary artery disease (CAD) underwent CTCA. The per-patient number of diseased coronary segments was determined and each diseased segment was classified as showing obstructive lesion (luminal narrowing >50%) or not. Coronary calcium scoring (CCS) was assessed too. Diabetics showed a higher number of diseased segments (4.1 {+-} 4.2 vs. 2.1 {+-} 3.0; p < 0.0001); a higher rate of CCS > 400 (p < 0.001), obstructive CAD (37% vs. 18% of patients; p < 0.0001), and fewer normal coronary arteries (20% vs. 42%; p < 0.0001), as compared to nondiabetics. The percentage of patients with obstructive CAD paralleled increasing CCS in both groups. Diabetics with CCS {<=} 10 had a higher prevalence of coronary plaque (39.6% vs. 24.5%, p = 0.003) and obstructive CAD (12.5% vs. 3.8%, p = 0.01). Among patients with CCS {<=} 10 all diabetics with obstructive CAD had a zero CCS and one patient was asymptomatic. Diabetes was associated with higher coronary plaque burden. The present study demonstrates that the absence of coronary calcification does not exclude obstructive CAD especially in diabetics. (orig.)

    Full Text Available AbstractBackground:Guidelines recommend that in suspected stable coronary artery disease (CAD, a clinical (non-invasive evaluation should be performed before coronary angiography.Objective:We assessed the efficacy of patient selection for coronary angiography in suspected stable CAD.Methods:We prospectively selected consecutive patients without known CAD, referred to a high-volume tertiary center. Demographic characteristics, risk factors, symptoms and non-invasive test results were correlated to the presence of obstructive CAD. We estimated the CAD probability based on available clinical data and the incremental diagnostic value of previous non-invasive tests.Results:A total of 830 patients were included; median age was 61 years, 49.3% were males, 81% had hypertension and 35.5% were diabetics. Non-invasive tests were performed in 64.8% of the patients. At coronary angiography, 23.8% of the patients had obstructive CAD. The independent predictors for obstructive CAD were: male gender (odds ratio [OR], 3.95; confidence interval [CI] 95%, 2.70 - 5.77, age (OR for 5 years increment, 1.15; CI 95%, 1.06 - 1.26, diabetes (OR, 2.01; CI 95%, 1.40 - 2.90, dyslipidemia (OR, 2.02; CI 95%, 1.32 - 3.07, typical angina (OR, 2.92; CI 95%, 1.77 - 4.83 and previous non-invasive test (OR 1.54; CI 95% 1.05 - 2.27.Conclusions:In this study, less than a quarter of the patients referred for coronary angiography with suspected CAD had the diagnosis confirmed. A better clinical and non-invasive assessment is necessary, to improve the efficacy of patient selection for coronary angiography.

    Full Text Available Globally, heart disease is the leading cause of death for both men and women. One in every four people is afflicted with and dies of heart disease. Early and accurate diagnoses of heart disease thus are crucial in improving the chances of long-term survival for patients and saving millions of lives. In this research, an advanced ensemble machine learning technology, utilizing an adaptive Boosting algorithm, is developed for accurate coronary heart disease diagnosis and outcome predictions. The developed ensemble learning classification and prediction models were applied to 4 different data sets for coronary heart disease diagnosis, including patients diagnosed with heart disease from Cleveland Clinic Foundation (CCF, Hungarian Institute of Cardiology (HIC, Long Beach Medical Center (LBMC, and Switzerland University Hospital (SUH. The testing results showed that the developed ensemble learning classification and prediction models achieved model accuracies of 80.14% for CCF, 89.12% for HIC, 77.78% for LBMC, and 96.72% for SUH, exceeding the accuracies of previously published research. Therefore, coronary heart disease diagnoses derived from the developed ensemble learning classification and prediction models are reliable and clinically useful, and can aid patients globally, especially those from developing countries and areas where there are few heart disease diagnostic specialists.

    2011-01-01

    Full Text Available BACKGROUND: In Brazil, despite the recommendations of the Brazilian Society of Hemodynamics and Interventional Cardiology, the National Health System has not yet approved the use of drug-eluting stents. In percutaneous coronary interventions performed in the public and part of the private health care system, bare metal stents are used as the only option. Therefore, new information on bare metal stents is of great importance. The primary endpoint was to evaluate the influence of the alloy and the profile of coronary stents on late loss and restenosis rates 6 months after implantation in patients with multivessel coronary disease. METHODS: Single center, randomized and prospective study comparison of cobalt-chromium versus stainless steel stent implantation in 187 patients with multivessel coronary disease. At least one cobalt-chromium and one stainless steel stent were implanted per patient. RESULTS: Mean age of patients was 59.5 + 10.1 years with a prevalence of males (66.3% and patients with acute coronary syndrome (56%. Baseline clinical characteristics were similar with hypertension in 146 (78%, dyslipidemia in 85 (45.5% and diabetes in 68 (36.4%. Two hundred and twenty-nine cobalt-chromium and 284 stainless steel stents were implanted. Angiographic variables showed no statistically significant difference. Angiographic follow-up to 6 months after implantation showed similar late loss and restenosis rates. CONCLUSION: The use of two different alloys, stainless steel and cobalt-chrome stents, in the same patient and in the same vessel produced similar 6-month restenosis and late loss rates.

    Full Text Available BACKGROUND: Coronary artery disease (CAD may coexist with extracranial carotid artery stenosis (ECAS, but the influence of CAD on procedure-related complications after carotid artery stenting (CAS has not been well investigated. The study aimed to determine the impact of CAD on the occurrence of peri-CAS cerebral ischemic lesions on diffusion-weighted imaging (DWI scanning. METHODS: Coronary angiography was performed within six months before CAS. DWI scanning was repetitively done within 1 week before and after CAS. Clinical outcome measures were stroke, angina, myocardial infarction and death within 30 days. RESULTS: Among 126 patients (69.5±9.0 years recruited for unilateral protected CAS, 33 (26% patients had peri-CAS DWI-positive lesions. CAD was noted in 79% (26 in 33 and 48% (45 in 93 of patients with and without peri-CAS DWI-positive lesions (OR, 4.0; 95% CI, 1.6-10.0; P = .0018, and the number of concomitant CAD on coronary angiography was positively correlated with the risk for peri-CAS DWI-positive lesions (P = .0032. In patients with no CAD (n = 55, asymptomatic CAD (n = 41 and symptomatic CAD (n = 30, the occurrence rates of peri-CAS DWI-positive lesions were 13%, 41% and 30% (P = .0048, and the peri-CAS stroke rates were 2%, 7% and 0% (P = .2120. CONCLUSIONS: The severity of morphological CAD and the presence of either symptomatic or asymptomatic CAD are associated with the occurrence of peri-CAS cerebral ischemic lesions.

    Background: Coronary heart disease patients and end-stage renal disease patients have been documented to have an increased amount of coronary artery calcifications (CAC). Purpose: To evaluate the distribution of CAC and its influence on interscan variability of measurement in end-stage renal disease and coronary heart disease patients, proven to have calcifications. Material and Methods: 69 patients having CAC, including 34 with coronary heart disease and 35 with end-stage renal disease, were scanned twice with multidetector-row computed tomography (MDCT). Amount of CAC was determined as the number of calcified lesions (CN), total calcium score (CS), calcium volume (CV), and calcium mass (CM). Distribution of CAC was evaluated on a per-patient basis as the median CS and CM of a single lesion. Density of the calcifications was calculated as the patient's CM divided by CV. Results: The overall median CS was 457.2, and the median CM was 75.6 mg. There were no significant differences in the number of calcified lesions, CS, or CM between the two groups. Both CS and CM of a single lesion, as well as the mean calcium density were lower in renal disease patients (P<0.05) than in coronary heart disease subjects. The relative interscan variability of coronary calcium measurement was higher in the renal disease group (P<0.05). There was a negative correlation between the calcium concentration and the relative interscan variability. Conclusion: The results indicate that the coronary calcium distribution influences the measurement interscan reproducibility, and the distribution may differ between end-stage renal disease patients and coronary heart disease patients, reflecting the dissimilar nature of coronary calcifications in those groups.

    Full Text Available Acute pulmonary edema is a serious event. Its occurrence in association with interrupted aortic arch and coronary heart disease is rare. Recently, an old patient developed cardiogenic shock and acute pulmonary edema due to acute coronary insufficiency, associated with interrupted aortic arch. The coronary angiography revealed occlusion of the right coronary artery and 95% obstruction in the left main coronary artery, associated with interruption of the descending aorta. Coronary artery bypass graft was performed, without extracorporeal circulation, to the anterior descending coronary artery. We discuss the initial management, given the seriousness of the case.

    Objective To analyse the effects of different therapies on coronary artery disease (CAD).Methods A total of 1055 patients who suffered from CAD diagnoised by coronary angiograpy were divided into three groups, namely pure drug therapy, percutanious coronary intervention (PCI) and coronary artery bypass graft (CABG) groups. Follow up was carried out from March to May in 2001, and the major adverse cardiac events (MACEs) including death, no-lethal myocardial infarction (MI) and revascularization were observed. In long-term observation, angina reoccured, and their improvement was evaluated. The short-term period was defined as the duration of 30 days after discharge, and the long term period was defined as the duration from 30 days after discharge.Results In the long-term period, the recurrences of angina both in PCI group and CABG group were lower than pure drug group (P 0.018, 0.002 respectively). No differences about long-term endpoint events were observed among these three groups (P>0.05). Forty-two patients suffering from left main coronary disease were intervened by the three therapies, and there was no death or MI both in PCI and CABG groups, three patients died and suffered from AMI in pure drug therapy group (P=0.015). In the short-term period, mortality in CABG group (5.77%) was higher than those in the other two groups (1.91% for PCI, and 1.40% for medical therapy, P=0.002), and no obvious difference observed in the latter two groups. No significance was concluded about the recent MI among this three groups (P=0.357). There were no differences on revascularization in these three groups.Conclusions Percutanious coronary interventions can not only reduce the attack of angina but also improve the life quality of patients, however it can not improve the long-term existance but left main CAD.

    Hepatocyte growth factor (HGF) is an endothelial cell specific growth factor involved in the repair of endothelial cells and collateral formation, however, the role for coronary artery disease is still unknown. We measured serum HGF level in various coronary artery diseases to examine the clinical significance. Serum HGF level was measured using the enzyme-linked immunosorbent assay method in patients with stable effort angina pectoris (n = 26), old myocardial infarction (n = 18), unstable angina pectoris (UAP; n = 10) and acute myocardial infarction (AMI; n = 21). As a control group, we selected 11 patients with neurocirculatory asthenia. Blood samples from peripheral veins were collected at cardiac catheterization before heparin administration. In the AMI group, blood samples were also collected at 48, 72 hr, 1, 2, 3 and 4 weeks from the peripheral veins and 48 and 72 hr after reperfusion from the coronary sinus. Serum HGF level was significantly higher in the UAP (0.41 +/- 0.12 ng/ml, p < 0.001) and AMI groups (0.38 +/- 0.26 ng/ml, p < 0.05) compared to the control group (0.19 +/- 0.09 ng/ml). Serum HGF level peaked 48 hr after reperfusion in both the peripheral veins (0.42 +/- 0.16 ng/ml) and coronary sinus (0.58 +/- 0.23 ng/ml) in the AMI group, with a significantly higher level in the coronary sinus than the peripheral veins (p < 0.05). No significant correlation between peak HGF level in the peripheral veins and peak creatine kinase (CK), CK-MB, ejection fraction and cardiac index was observed. Serum HGF was elevated in acute coronary syndrome, indicating advanced endothelial cell damage. HGF is produced, at least partially, in the heart in patients with AMI. Serum HGF level may be useful to detect endothelial cell damage rather than myocardial cell damage.

    Full Text Available Significant left main coronary artery (LMCA stenosis is not rare and reported 3 to 10% of patients undergoing coronary angiography. Unprotected LMCA intervention is a still clinical challenge and surgery is still going to be a traditional management method in many cardiac centers. With a presentation of drug eluting stent (DES, extensive use of IVUS and skilled operators, number of such interventions increased rapidly which lead to change in recommendation in the guidelines regarding LMCA procedures in the stable angina (Class 2a recommendation for ostial and shaft lesion and class 2b recommendation for distal bifurcation lesion. However, there was not clear consensus about the management of unprotected LMCA lesion associated with acute myocardial infarction (MI with a LMCA culprit lesion itself or distinct culprit lesion of other major coronary arteries. Surgery could be preferred as an obligatory management strategy even in the high risk patients. With this review, we aimed to demonstrate treatment strategies of LMCA disease associated with acute coronary syndrome, particularly acute myocardial infarction (MI. In addition, we presented a short case series with LMCA lesion and ST elevated acute MI in which culprit lesion placed either in the left anterior descending artery or circumflex artery. We reviewed the current medical literature and propose simple algorithm for management.

    To evaluate the prevalence of coexistent coronary artery disease (CAD) or myocardial bridging (MB) in patients with hypertrophic cardiomyopathy (HCM) using coronary CT angiography (CCTA) and assess the role of CCTA. The prevalence of obstructive CAD (> 50% luminal reduction) and MB (partial and full encasement) were assessed in 150 patients with HCM diagnosed by clinical findings, electrocardiography, and echocardiography of 19588 consecutive patients who underwent CCTA for suspected CAD. The overall feasibility of coronary artery visualization was 98.9% with CCTA. In patients with HCM, the prevalence of obstructive CAD and MB (14.7% partial and 28.0% full encasement) were 23.3% and 42.7%, respectively. Age, hypertension, family history of premature CAD, Framingham risk score and severe chest pain were associated with CAD, whereas male gender and septal type were associated with MB (all p < 0.05). In comparison to invasive coronary angiography (n = 37), the diagnostic accuracy of CCTA for the detection of CAD and full encasement MB was 89.2% and 86.5%, respectively. One-quarter of patients with HCM had coexistent obstructive CAD or full encasement MB. CCTA can be a feasible and accurate noninvasive imaging modality for the detection of CAD and MB in patients with HCM.

    Background Noninvasive cardiac imaging is now central to the diagnosis and management of patients with moderate probability for coronary artery disease. The aim of this study was to assess the impact of stress myocardial perfusion single photon emission computerized tomography (SPECT) on in-hospital coronary angiography and revascularization for such patients.Methods Between January 2005 and June 2007, 1053 consecutive in-hospital patients (423 women, the average age of (57.2±11.2) years) with suspected coronary artery disease but without any prior interventional treatment were retrospectively analyzed. All patients underwent a 2-day stress/rest 99m Tc-methoxyisobutylisonitrile (MIBI) myocardial perfusion SPECT, including 984 exercise test and 69 adenosine test.Results Overall, stress/rest myocardial perfusion SPECT was normal in 973 patients (92.4%) and abnormal in 80 patients (7.6%). A total of 190 patients underwent coronary angiography, 46 underwent percutaneous coronary intervention and 10 coronary artery bypass grafting during hospitalization. From the whole perspective, only 14.7% of patients with normal SPECT underwent coronary angiography, so did 58.8% of patients with abnormal SPECT (x2=97.0,P<0.001); furthermore, the rates of revascularization in patients with normal and abnormal SPECT were 2.8% and 36.3%,respectively (27 out of 973 vs. 29 out of 80, x2=157.9, P<0.001). The extent and severity of ischemia did not add more predictive value for subsequent coronary angiography, but did have impact on revascularization. Multivariate analysis showed that reversible perfusion defect was the most predictive variable for referral rate to coronary angiography (odds ratio=7.5, P<0.001).Conclusions Abnormal myocardial perfusion SPECT is a powerful referral for in-hospital coronary angiography and revascularization during the same hospitalization. Thus, stress/rest SPECT is an effective gatekeeper for early coronary angiography and invasive treatment for

    Objective To investigate the genetic association between the inducible nitric oxide synthase (NOS) 2A gene and stroke with a history of coronary artery disease ( CAD). Methods 708 patients with stroke and 235 healthy controls were recruited in this study, and the stroke group was delaminated into 2 subgroups according to the history of CAD. SNP rs28944190, an A to C base change located in intron 22 of the gene, was used as a genetic marker. PCR-based restriction fragment length polymorphism analysis was applied to genotype rs28944190 (Hac Ⅲ site). Results The x2 test showed no association between patients with stroke and healthy controls. Of 708 patients, 94 had a history of CAD and the frequency of allele C of rs28944190 was significantly higher in patients with a history of CAD than those without (23.9% vs 16.6%, x2 =5.629, df= 1, P =0.018, OR = 1.580, 95% CI 1.083—2.306), especially in male patients (x2 = 8. 592, df= 1, P = 0. 003, OR = 1. 983, 95% CI 1. 255—3. 134). The frequency of genotype AA + AC of rs28944190 was significantly higher in patients with a history of CAD than those without such a history (47.9% vs 30. 8%, x2 = 10. 761, df= 1, P = 0. 001, OR = 2. 065, 95% CI 1.34—3.19), especially in male patients (x2 = 15. 762, df= 1, P =0. 000, OR =2. 985, 95% CI 1.74—5. 12).

    To verify genetic determinants associated with stroke in children with sickle cell disease (SCD). Prospective cohort with 110 children submitted to neonatal screening by the Neonatal Screening Program, between 1998 and 2007, with SCD diagnosis, followed at a regional reference public service for hemoglobinopathies. The analyzed variables were type of hemoglobinopathy, gender, coexistence with alpha thalassemia (α-thal), haplotypes of the beta globin chain cluster, and stroke. The final analysis was conducted with 66 children with sickle cell anemia (SCA), using the chi-squared test in the program SPSS(®) version 14.0. Among children with SCD, 60% had SCA. The prevalence of coexistence with α-thal was 30.3% and the Bantu haplotype (CAR) was identified in 89.2%. The incidence of stroke was significantly higher in those with SCA (27.3% vs. 2.3%; p=0.001) and males (24.1% vs. 9.6%; p=0.044). The presence of α-thal (p=0.196), the CAR haplotype (p=0.543), and socioeconomic factors were not statistically significant in association with the occurrence of stroke. There is a high incidence of stroke in male children and in children with SCA. Coexistence with α-thal and haplotypes of the beta globin chain cluster did not show any significant association with stroke. The heterogeneity between previously evaluated populations, the non-reproducibility between studies, and the need to identify factors associated with stroke in patients with SCA indicate the necessity of conducting further research to demonstrate the relevance of genetic factors in stroke related to SCD.

    Lipid profile management is even more critical in patients treated for secondary prevention, since patients with established coronary heart disease are at higher risk of developing events. Current guidelines encourage lifestyle modification and patient engagement in disease prevention. However, the American College of Cardiology/American Heart Association guidelines seem to differ considerably from their predecessors, having an impact on clinical practice of lipid management. Area covered: This review article discusses and provides a summary of the current recommendations for lipid profile management in patients with coronary heart disease, with a view to present lifestyle modification and novel treatment strategies, and to indicate areas of dispute among recent guidelines. Expert commentary: Existing controversies between current guidelines concerning treatment goals and therapeutic decisions may have potential implications on the clinical management of patients. In the meantime, we eagerly wait for the results of randomized controlled trials evaluating promising, potent, safe and prolonged drugs that are in progress.

    Full Text Available Introduction: Coronary artery disease (CAD is as a leading cause of death and disability all around the world. Multiple risk factors have a role in the development and progression of coronary heart disease (CHD. It is necessary to control risk factors, to achieve optimal results of treatment. The aim of present study was to evaluate the persistence of cardiovascular risk factors in patients with CADs after percutaneous cardiac interventions. Methods: In an analytical-descriptive study, 150 patient with CAD and percutaneous coronary intervention (PCI were performed for them, and referred to Cardiology Clinic of Shahid Madani Hospital of Tabriz University of Medical Sciences, Tabriz, Iran, from September 2013 to September 2015, were studied. The persistence of coronary risk factors, 12-24 months after performing PCI, was evaluated. Results: The mean age of patients at time of PCI performing was 57.90 ± 12.26 years. 72.7% of patients were male and 27.3% were female and male to female ratio was 1 to 0.37. Dyslipidemia in 52.0% of patients, hypertension in 51.3% patients, and diabetes mellitus (DM in 41.3% patients were the most common underlying comorbidities. In both before and after doing PCI, 26.7% were a smoker, and smoking rates after doing PCI also showed no significant change (P = 0.055, and also there were no significant changes in the physical activity of patients compared before and after performing PCI. Conclusion: Based on the findings of the present study, dyslipidemia, hypertension, and DM, was the most frequent underlying diseases in patients with CAD respectively. Risk factors such as smoking, and lack of exercise, had no significant changes after performing PCI.

    2016-01-01

    Background:Angiopoietin-2 (Ang-2) plays a crucial role in hypoxia-induced angiogenesis and is expressed only in sites of vascular remodeling.Ang-2 expression can be regulated by hypoxia inducible factors and other regulators with exposure to hypoxia.The objective of this study was to investigate the influence of percutaneous coronary intervention (PCI) on serum Ang-2 concentrations,and analyze the correlation between serum Ang-2 and the severity of coronary artery stenosis in patients with coronary heart disease (CHD).Methods:Sixty-four patients with CHD were selected as the study group,each undergone PCI.Thirty-two healthy subjects were selected as the control group.Pre-PCI and post-PCI serum Ang-2 were measured by enzyme-linked immunosorbent assay.The severity of coronary artery stenosis was evaluated using angiographic Gensini scores,and the coronary collateral vessels were scored according to Rentrop's classification.Results:Concentrations of pre-PCI serum Ang-2 in the study group were significantly higher than those in the control group (4625.06 ± 1838.06 vs.1945.74 ± 1588.17 pg/ml,P < 0.01);however,concentrations of post-PCI serum Ang-2 were significantly lower than those of pre-PCI (3042.63 ± 1845.33 pg/ml vs.4625.06 ± 1838.06 pg/ml,P < 0.01).Concentrations of pre-PCI serum Ang-2 were significantly correlated with Gensini scores (r =0.488,P < 0.01);however,the decrease in serum Ang-2 after PCI was not correlated with Gensini scores,coronary collateral vessel grading,or left ventricular ejection fraction.Conclusions:Serum Ang-2 concentrations significantly increased in patients with CHD,and PCI treatment significantly decreased these concentrations.Serum Ang-2 concentrations,but not the decrease in serum Ang-2 concentrations,were significantly correlated with the severity of coronary artery stenosis.These results suggested that Ang-2 may be a biomarker of myocardial ischemia and vessel remodeling.

    Visceral obesity is among the known risk factors of atherosclerotic cardiovascular diseases. As long as adipose tissue was considered only an inert store of excess energy, accumulated in triglycerides, explanation of the mechanisms causing increased cardiovascular risk in obesity was difficult. Finding that the adipose tissue is an active endocrine organ and that the adipokines secreted in it influence several metabolic processes, allowed better understanding of this correlation. Several disturbances in secretion, function and balance of adipokines occur in the course of obesity. Changes of adiponectin, leptin and resistin concentrations are among the reasons of accelerated atherosclerosis occurring in the visceral adiposity. Adiponectin concentrations are decreased in visceral adiposity. Adiponectin is adipokine possessing antiatherogenic properties. It's effects exerted though the specific receptors in skeletal muscles and liver include decreased insulin resistance and improved plasma lipid profile. Acting directly in the vessel wall adiponectin prevents development of atheromatic lesions by inhibiting production of adhesive molecules and formation of foam cells. It has been found that decreased adiponectin concentrations are connected not only with increased coronary risk but also with progression of atherosclerosis in coronary vessels. Moreover it was found that adiponectin plasma concentration is significantly decreased in acute coronary incidences. Leptin regulates energy metabolism and balance. The concentrations of this adipokine are increased in obesity and correlate with insulin resistance. Hiperleptinemia has been also recognized as cardiovascular diseases risk factor. Resistin is considered to be a substance increasing insulin resistance, however the exact mechanisms are not known. Resistin plasma concentrations are increased in obese subjects and correlate with the inflammatory state that underlies the initiation and progression of atherosclerotic

    2017-08-01

    Kawasaki disease (KD) is an acute vasculitis of unknown origin and predominant in males. The long-term effects of the disease depend on whether there are coronary lesions, particularly aneurysms. The prognosis of patients with giant aneurysms is very poor due to their natural progression to coronary thrombosis or severe obstructive lesions. A series of 8 cases is presented where the epidemiology and diagnostic methods are described. The treatment of the acute and long-term cardiovascular sequelae is also reviewed. A descriptive analysis was conducted on patients admitted to the Paediatric Cardiology Unit of La Fe University Hospital (Valencia) with KD and a coronary lesion. More than one artery was involved in all patients. Although early diagnosis was established in only two cases, none of the patients had severe impairment of ventricular function during the acute phase. Treatment included intravenous gammaglobulin and acetylsalicylic acid at anti-inflammatory doses during the acute phase. A combination of dual antiplatelet therapy and corticosteroids was given in cases of coronary thrombosis. The silent aneurysms continue to persist. KD is the most common cause of acquired heart disease in children. The delay in diagnosis is associated with a greater likelihood of coronary lesions that could increase the risk of cardiovascular events in adulthood. Thus, this subgroup requires close clinical monitoring for a better control of cardiovascular risk factors over time. Copyright © 2016 Asociación Española de Pediatría.

    Full Text Available Cardiovascular is the major cause of death in chronic kidney disease and end-stage renal disease. The cardiovascular mortality rate of patients with renal impairment is evaluated to be higher than general population. Coronary artery disease seems to be an important type of cardiovascular complication among patients with chronic kidney disease and end-stage renal disease before the renal replacement therapy. Due to the strong association between chronic kidney disease and the incidence of coronary artery disease, accurate screening, diagnosis, and management of cardiovascular complications would be essential in patients at different stages of renal dysfunction. Despite the need for the comprehensive knowledge about different aspects of coronary artery disease in patients with renal failure, there is not sufficient evidence regarding the pathophysiology, ideal diagnosis, and treatment strategies for coronary heart disease in population with chronic kidney disease. In this study, we briefly reviewed the existing literatures about the possible screening, diagnosis, and the treatment approaches of risk of coronary heart disease in patients with kidney dysfunction.

    Multislice Cr angiography represents one of the most exciting technological revolutions in cardiac imaging and it has been increasingly used in the diagnosis of coronary artery disease.Rapid improvements in multislice CT scanners over the last decade have allowed this technique to become a potentially effective alternative to invasive coronary angiography in patients with suspected coronary artery disease.High diagnostic value has been achieved with multisfice CT angiography with use of 64-and more slice CT scanners.In addition,multislice CT angiography shows accurate detection and analysis of coronary calcium,characterization of coronary plaques,as well as prediction of the disease progression and major cardiac events.Thus,patients can benefit from multislice CT angiography that provides a rapid and accurate diagnosis while avoiding unnecessary invasive coronary angiography procedures.The aim of this article is present an overview of the clinical applications of multislice CT angiography in coronary artery disease with a focus on the diagnostic accuracy of coronary artery disease;prognostic value of coronary artery disease with regard to the prediction of major cardiac events; detection and quantification of coronary calcium and characterization of coronary plaques.Limitations of multislice Cr angiography in coronary artery disease are also briefly discussed,and future directions are highlighted.

    The long-term outcome of percutaneous coronary intervention (PCI) compared to coronary artery bypass grafting (CABG) for unprotected left main coronary artery disease (ULMCAD) remains to be investigated. We identified 1,005 patients with ULMCAD of 15,939 patients with first coronary revascularization enrolled in the CREDO-Kyoto PCI/CABG Registry Cohort-2. Cumulative 3-year incidence of a composite of death/myocardial infarction (MI)/stroke was significantly higher in the PCI group than in the CABG group (22.7% vs 14.8%, p = 0.0006, log-rank test). However, the adjusted outcome was not different between the PCI and CABG groups (hazard ratio [HR] 1.30, 95% confidence interval [CI] 0.79 to 2.15, p = 0.30). Stratified analysis using the SYNTAX score demonstrated that risk for a composite of death/MI/stroke was not different between the 2 treatment groups in patients with low (<23) and intermediate (23 to 33) SYNTAX scores (adjusted HR 1.70, 95% CI 0.77 to 3.76, p = 0.19; adjusted HR 0.86, 95% CI 0.37 to 1.99, p = 0.72, respectively), whereas in patients with a high SYNTAX score (≥33), it was significantly higher after PCI than after CABG (adjusted HR 2.61, 95% CI 1.32 to 5.16, p = 0.006). In conclusion, risk of PCI for serious adverse events seemed to be comparable to that after CABG in patients with ULMCAD with a low or intermediate SYNTAX score, whereas PCI compared with CABG was associated with a higher risk for serious adverse events in patients with a high SYNTAX score.

    We aimed to investigate the relationship between ABO blood groups and complexity of coronary lesions assessed by SYNTAX score (SS) in stable coronary artery disease (CAD) patients. Our cross-sectional and observational study population consisted of 559 stable CAD patients. From all patients, ABO blood group was determined and the SS was calculated as low SYNTAX score (0-22), intermediate SYNTAX (23-32) score and high SYNTAX score (>32). Statistical analysis was performed using Student's t-test or Mann-Whitney U test, ANOVA, or Kruskal-Wallis test and chi-square test. Multiple logistic regression analysis was used to identify the independent predictors of high SS. The analysis between the SS tertiles revealed that the frequency of non-O blood group was significantly higher in the upper SS tertiles (56.2% vs. 75.9 vs. 80.2%, pABO blood groups and complexity of angiographic CAD.

    Increased platelet aggregation during antiplatelet therapy may predict cardiovascular events in patients with coronary artery disease. The majority of these patients receive aspirin monotherapy. We aimed to investigate whether high platelet-aggregation levels predict cardiovascular events in stable coronary artery disease patients treated with aspirin. We included 900 stable coronary artery disease patients with either previous myocardial infarction, type 2 diabetes mellitus, or both. All patients received single antithrombotic therapy with 75 mg aspirin daily. Platelet aggregation was evaluated 1 hour after aspirin intake using the VerifyNow Aspirin Assay (Accriva Diagnostics) and Multiplate Analyzer (Roche; agonists: arachidonic acid and collagen). Adherence to aspirin was confirmed by serum thromboxane B2. The primary end point was the composite of nonfatal myocardial infarction, ischemic stroke, and cardiovascular death. At 3-year follow-up, 78 primary end points were registered. The primary end point did not occur more frequently in patients with high platelet-aggregation levels (first versus fourth quartile) assessed by VerifyNow (hazard ratio: 0.5 [95% CI, 0.3-1.1], P=0.08) or Multiplate using arachidonic acid (hazard ratio: 1.0 [95% CI, 0.5-2.1], P=0.92) or collagen (hazard ratio: 1.4 [95% CI, 0.7-2.8], P=0.38). Similar results were found for the composite secondary end point (nonfatal myocardial infarction, ischemic stroke, stent thrombosis, and all-cause death) and the single end points. Thromboxane B2 levels did not predict any end points. Renal insufficiency was the only clinical risk factor predicting the primary and secondary end points.

    Full Text Available Yuelong Jin,* Lianping He,* Quanhai Wang, Yan Chen, Xiaohua Ren, Hui Tang, Xiuli Song, Lingling Ding, Qin Qi, Zhiwei Huang, Jiegen Yu, Yingshui Yao Department of Preventive Medicine, Wannan Medical College, Wuhu, People's Republic of China *These authors contributed equally to this work Background: Numerous studies have reported that low calcium intake is related to a higher prevalence of cardiovascular disease. However, the relationship between serum calcium and coronary heart disease is unclear. The purpose of this study was to compare serum calcium levels in patients with coronary heart disease and those in healthy individuals. Methods: This retrospective, case-control study conducted in the People's Republic of China comprised 380 cases and 379 controls. Serum calcium levels, blood lipids, and anthropometric measurements were measured in both groups. The Student's unpaired t-test or Chi-square test was used to compare differences between cases and controls. Pearson's partial correlation coefficient was used to determine the association between serum calcium, blood lipids, and blood pressure in both groups. Results: Our results indicate that the average level of serum calcium in cases was higher than in controls. Serum calcium levels showed no correlation with any parameter except for triglycerides in either group. Conclusion: Overall, these data suggest that serum calcium has no influence on coronary heart disease or triglyceride levels in the general population. Keywords: serum calcium, hypertension, blood lipids

    To evaluate the association between periodontal disease, tooth loss and coronary heart disease (CHD). There is still controversy about the relationship between periodontal disease and tooth loss with vessel obstruction assessed using coronary angiography. This cross-sectional study included 195 patients that underwent coronary angiography and presented with at least six teeth. Patients were classified into three categories of coronary obstruction severity: absence; one or more vessels with ≤ 50% obstruction; and one or more vessels with ≥ 50% obstruction. The extent of coronary obstruction was dichotomized into 0 and ≥ 1 affected vessels. A periodontist blinded to patient CHD status conducted a full mouth examination to determine mean clinical attachment loss, mean periodontal probing depth and tooth loss. Multiple logistic regression models were applied adjusting for age, gender, hypertension, smoking, body mass index, low-density lipoprotein cholesterol and C-reactive protein. Most patients were males (62.1%) older than 60 years (50.8%), and 61% of them had CHD. Mean periodontal probing depth, clinical attachment loss and tooth loss were 2.64 ± 0.72 mm, 4.40 ± 1.31 mm and 12.50 ± 6.98 teeth respectively. In the multivariable models, tooth loss was significantly associated with a higher chance of having at least one obstructed vessel (odds ratio = 1.04; 95% confidence interval 1.01-1.09) and with vessel obstruction ≥ 50% (odds ratio = 1.06; 95% confidence interval 1.01-1.11). No significant associations were found between periodontal variables and vessel obstruction. Tooth loss was found to be a risk indicator for CHD. © 2015 John Wiley & Sons A/S.

    The present retrospective study examines the influence of disease management programs on nonfatal stroke in type 2 diabetes mellitus (T2DM) patients in Germany. The evaluation is based on retrospective patient data from the Disease Analyzer (IMS Health). The analysis included 169 414 T2DM patients aged 40 years and older with an initial prescription of antihyperglycemic therapy between January 2004 and December 2014. A total of 86 713 patients participated in a disease management program (DMP) for T2DM and 82 701 patients received standard care. The main outcome measure of this study was nonfatal stroke. Kaplan-Meier curves of DMP and SC patients were compared using log rank test. The Cox proportional hazards model was used to provide an adjusted estimate of the DMP effect. It is apparent from the baseline characteristics that the general health of patients receiving standard care was poorer than that of patients participating in a DMP. The baseline HbA1c value was 7.6% in the DMP group and 7.8% in the SC group. Furthermore, the SC group had a higher proportion of preexisting conditions, such as coronary heart disease (CHD), peripheral arterial occlusive disease (pAOD), and renal insufficiency. The proportion of patients who received insulin in first year therapy was higher in the SC group. Time to event analysis showed that DMP was associated with a delayed occurrence of stroke, because stroke occurred an average of 350 days later in DMP patients than in patients receiving SC (DMP: 1.216 days, RV: 866 days). The Cox model with covariable adjustment confirmed the significant association of DMPs with nonfatal stroke in patients with type 2 diabetes mellitus (HR 0.71; 95% CI: 0.69-0.74). The present study indicates that DMPs are positively associated with stroke. The possible reasons for this must be verified in further studies.

    A pediatric population at high risk for the development of coronary artery disease has been identified. Using a simple and inexpensive protocol, serum cholesterol determinations were performed on 50 children 12 years old and younger. These children were taken from 28 families in which one parent had suffered a myocardial infarction before the age of 50. Eight of the 50 children were found to have significant elevation of serum cholesterol. This was an incidence of 16%--twice that of the general pediatric population. Subjects with both adverse genetic and metabolic backgrounds need to be identified in this simple way. Preventive and therapeutic measures in such children may alter in the future the serious morbidity and mortality of coronary artery disease.

    Full Text Available Abstract Background Few studies have focused on the association between the sociodemographic characteristics of a patient with the change in health-related quality of life (HRQOL following invasive coronary procedures, and the results remain inconclusive. The objective of the present study was to measure the temporal changes in HRQOL of patients with coronary heart disease, and assess how these changes are associated with invasive coronary procedures and sociodemographic characteristics. Methods This was a prospective study of 254 patients with angina pectoris and 90 patients with acute coronary syndrome. HRQOL was assessed with the multi-item scales and summary components of the SF-36, both 6 weeks and 2 years after baseline hospitalization in 1998. Paired t-tests and multiple regression analyses were used to assess temporal changes in HRQOL and to identify the associated factors. Results Physical components of HRQOL had improved most during the 2 years following invasive coronary procedures. Our findings indicated that patients with angina pectoris who were younger, male, and more educated were most likely to increase their HRQOL following invasive coronary procedures. When adjusting for baseline HRQOL scores, invasive coronary procedures and sociodemographic characteristics did not explain temporal changes in patients with acute coronary syndrome, possibly due to higher comorbidity. Conclusion Sociodemographic characteristics should be taken into account when comparing and interpreting changes in HRQOL scores in patients with and without invasive coronary procedures.

    Aims: The aim was to review epidemiologic studies to reassess whether serum levels of triglycerides should be considered independently of high-density lipoprotein-cholesterol (HDL-C) as a predictor of coronary heart disease (CHD). Methods and results: We systematically reviewed population-based cohort studies in which baseline serum levels of triglycerides and HDL-C were included as explanatory variables in multivariate analyses with the development of CHD (coronary events or coronary death) as dependent variable. A total of 32 unique reports describing 38 cohorts were included. The independent association between elevated triglycerides and risk of CHD was statistically significant in 16 of 30 populations without pre-existing CHD. Among populations with diabetes mellitus or pre-existing CHD, or the elderly, triglycerides were not significantly independently associated with CHD in any of 8 cohorts. Triglycerides and HDL-C were mutually exclusive predictors of coronary events in 12 of 20 analyses of patients without pre-existing CHD. Conclusions: Epidemiologic studies provide evidence of an association between triglycerides and the development of primary CHD independently of HDL-C. Evidence of an inverse relationship between triglycerides and HDL-C suggests that both should be considered in CHD risk estimation and as targets for intervention. PMID:19436658

    Coronary artery disease (CAD) diminishes local, regional, or global blood supply to the heart and is most commonly caused by coronary atherosclerosis. New insights into the etiology of atherosclerosis suggest that CAD is an inflammatory disorder that responds well to modulation rather than an unchangeable chronic process. Since 75% of all acute coronary syndromes result from rupture of atherosclerotic plaques, factors causing rupture have a crucial role. Magnetic resonance imaging and CT have the potential to visualize the composition of coronary artery plaques and thus to identify plaques at risk. Considering the new insights into stunning and hibernation, myocardial late enhancement on MRI might provide pivotal information for therapeutic decision making among lysis therapy, catheter intervention, and bypass surgery. Exercise electrocardiography without or with right precordial leads, stress echocardiography, and stress scintigraphy are simple clinical procedures to identify CAD with high sensitivities of 67, 92, 76, and 88%, respectively. The MRI and CT have to be compared with these good results. Nevertheless, we are expecting that MRI and CT will replace the conventional diagnostic modalities, gain a central role in diagnosing patients with suspected CAD, and prove to be cost-effective in this regard.

    Coronary disease is analyzed through common lipid profiles, but these analyses fail to account for residual risk due to abdominal weight and elevated TG levels. We aimed to investigate the relationship between the waist circumference × triglyceride index (WT index) and the Coronary Artery Score (CAS) in patients with coronary heart disease. 346 patients in our Cardiology Department were recruited from September 2007 to August 2011 and divided into two groups according to whether the patients presented with metabolic syndrome. We performed coronary angiography using the standard Judkins method. The severity of coronary artery stenosis and the CAS were calculated and analyzed with a computerized quantitative analysis system. The signs index, which includes the body mass index (BMI), waist circumference, hip circumference, waist-hip-ratio, and waist-height-ratio, the blood glucose and blood lipid index of all the patients were collected and used to calculate the WT index (waist circumference x triglyceride index. We performed a correlative analysis with age, gender, body mass index, blood glucose and blood lipid, blood pressure and other risk indicators of all patients as the dependent variables and the CAS as the independent variable. We show that the CAS is positively correlated to the WT index. Several lipid profiles and waist circumference were significantly associated with the CAS. The WT index is correlated to the CAS and is a good predictor for the development of coronary artery disease; it can be applied in the clinic for early intervention in populations at risk for coronary heart disease.

However, the concept of using a permanent metallic endovascular device to restore the patency of a stenotic artery has inherited pitfalls, namely the presence of a foreign body within the artery causing vascular inflammation, late complications such as restenosis and stent thrombosis, and impeding the restoration of the physiologic function of the stented segment. Bioresorbable scaffolds (BRS were introduced to potentially overcome these limitations, as they provide temporary scaffolding and then disappear, liberating the treated vessel from its cage. Currently, several BRSs are available, undergoing evaluation either in clinical trials or in preclinical settings. The aim of this review is to present the new developments in BRS technology, describe the mechanisms involved in the resorption process, and discuss the potential future prospects of this innovative therapy.Keywords: bioresorbable scaffold, drug-eluting stent, biodegradable, design, mechanism, coronary artery disease

    To validate published prediction models for the presence of obstructive coronary artery disease (CAD) in patients with new onset stable typical or atypical angina pectoris and to assess the incremental value of the CT coronary calcium score (CTCS). We searched the literature for clinical prediction rules for the diagnosis of obstructive CAD, defined as {>=}50% stenosis in at least one vessel on conventional coronary angiography. Significant variables were re-analysed in our dataset of 254 patients with logistic regression. CTCS was subsequently included in the models. The area under the receiver operating characteristic curve (AUC) was calculated to assess diagnostic performance. Re-analysing the variables used by Diamond and Forrester yielded an AUC of 0.798, which increased to 0.890 by adding CTCS. For Pryor, Morise 1994, Morise 1997 and Shaw the AUC increased from 0.838 to 0.901, 0.831 to 0.899, 0.840 to 0.898 and 0.833 to 0.899. CTCS significantly improved model performance in each model. Validation demonstrated good diagnostic performance across all models. CTCS improves the prediction of the presence of obstructive CAD, independent of clinical predictors, and should be considered in its diagnostic work-up. (orig.)

    The aim of the research is to investigate the impact of coronary stenting on exercise tolerance after 4-8 week and after 12-15 months. The study involved total 90 patients with coronary artery disease, who underwent coronary stenting. All patients underwent clinical examination, including an assessment of their condition, the frequency of angina attacks, echocardioscopy, resting ECG was recorded in all the patients in the standard 12 -lead veloergometry. Statistical processing was performed using Statistica 6.0 for Windows, the method of Wald - Wolfowitz . Data are presented as arithmetic means and error average M ± m. We used a statistical method of calculation - the median ranks (with the median calculated by the usual rules of statistics - the arithmetic mean of the central members of the ordered series). Significant differences were assessed by t-test . The level of significance was considered significant when p <0,05. According to the monitoring data of patients have a significant increase in exercise tolerance: threshold power increased by 63% and in 12-15 months by 58 % compared with the original. The duration of the test conducted after stenting increased by almost 2 -fold. In addition, significantly reduced the proportion of patients whose test results were evaluated as positive. Stenting of the coronary arteries after 4-8 weeks promotes the significant increase in exercise tolerance that persists after 12-15 months. The factors of associated with insufficient increase in exercise tolerance after stenting according veloergometry are: female gender, diabetes, smoking cessation further contributes to the increase in the threshold of physical activity.

    The article assesses the influence of mono- and multivascular lesions of coronary arteries on the course of coronary heart disease at patients with diabetes mellitus type 2. For this purpose, a comprehensive survey of 75 patients with coronary heart disease and diabetes mellitus type 2 was arranged. Depending on the number of vascular lesions of the coronary arteries, according to the data of coronary arteries computer tomography, all patients were divided into two subgroups. The first subgroup included 27 patients with coronary heart disease and diabetes mellitus type 2 with monovascular lesions of coronary arteries. To the second subgroup were included 48 patients with coronary heart disease and diabetes mellitus type 2 with multivascular lesions of coronary arteries. During the analysis of carbohydrate metabolism in cases of coronary heart disease and diabetes mellitus type 2 the HOMA index increase by 25.40% and insulin level increase by 17.05% were revealed at patients with multivascular lesions of coronary arteries in comparison with patients with monovascular lesions of coronary arteries, respectively. The combination of coronary heart disease and diabetes mellitus type 2 with multivascular lesions of coronary arteries was associated with an increase of sortilin level (233,47±47,85 ng/l). A significant increase in triglycerides, lipoprotein cholesterol of very low density influences greatly on the progression of coronary atherosclerosis with lesions of greater number of coronary arteries at patients surveyed. At patients with coronary heart disease and diabetes mellitus type 2 with multivascular lesions of coronary arteries the left ventricle myocardial re-modeling occurred through the increase of left ventricle's size and cavity.

    Anomalous origin of the right coronary artery from the pulmonary artery (ARCAPA) is a rare anomaly. It may contribute to myocardial ischemia or sudden death, although the lesion is usually asymptomatic. We report a sudden death case of a 58-year-old man with ARCAPA coexisting with severe atherosclerotic coronary artery disease. He had been healthy until he complained of chest pain, several days before death, despite the discovery of heart murmur in childhood and suspicion of valvular heart disease. The autopsy revealed not only typical findings of the right coronary anomaly with well-developed collateral circulations but also severe atherosclerotic lesions of the left coronary artery, and ischemic change of the myocardium in the left and right coronary arterial perfusion territory. In addition to the "coronary steal" phenomenon primarily caused by ARCAPA, the reduced flow of both coronary arteries and further increase of "coronary steal" due to atherosclerotic obstructive coronary disease might have contributed to the patient's death.

    2016-01-01

    Improved surgical and medical therapy have prolonged survival in patients with congenital heart disease (CHD) such that general medical conditions like coronary artery disease (CAD) are now the main determinants of mortality. A summary of the association of CAD with CHD, as well as a discussion of the radiologic evaluation of the coronary arteries in adults with CHD is described herein. Cross sectional imaging to evaluate CAD in adults with CHD should follow the same appropriateness criteria as gender and aged matched patients without CHD. Coronary CT imaging may be particularly valuable in evaluating the coronary arteries in this patient population as invasive coronary angiography may prove challenging secondary to complicated or unconventional anatomy of the coronary arteries. Further, typical methods for evaluating CAD such as stress or echocardiography may be impractical in adults with CHD. Finally, delineating the anatomic relationship of the coronary arteries and their relationship with the sternum, chest wall, conduits, grafts, and valves is highly recommended in patients with CHD prior to reintervention to avoid iatrogenic complications.

The prevalence of coronary heart disease is promoted in turn by a high prevalence of cardiovascular risk factors, particularly smoking, hypertension, dyslipidemia, diabetes, and sedentary lifestyles. Patients in Africa and the Middle East present with myocardial infarction at a younger age, on average, compared with patients elsewhere. The projected future burden of mortality from coronary heart disease in Africa and the Middle East is set to outstrip that observed in other geographical regions. Recent detailed nationally representative epidemiological data are lacking for many countries, and high proportions of transient expatriate workers in countries such as Saudi Arabia and the United Arab Emirates complicate the construction of such datasets. However, the development of national registries in some countries is beginning to reveal the nature of coronary heart disease. Improving lifestyles (reducing calorie intake and increasing physical activity in patients in the region will be essential, although cultural and environmental barriers will render this difficult. Appropriate prescribing of pharmacologic treatments is essential in the prevention and management of cardiovascular disease. In particular, recent controversies relating to the therapeutic profile of beta-blockers may have reduced their use. The

    To describe perceived social support among patients with coronary heart disease following percutaneous coronary intervention. A low level of social support is considered a risk factor for coronary heart disease in healthy individuals and reduces the likelihood that people diagnosed with coronary heart disease will have a good prognosis. A descriptive cross-sectional study. A survey of 416 patients was conducted in 2013. A self-report instrument, Social Support of People with Coronary Heart Disease, was used. The instrument comprises three dimensions of social support: informational, emotional, functional supports and 16 background variables. Data were analysed using descriptive statistics, factor analysis, mean sum variables and multivariate logistic regression. Perceived informational support was primarily high, but respondents' risk factors were not at the target level. The weakest items of informational support were advice on physical activity, continuum of care and rehabilitation. Regarding the items of emotional support, support from other cardiac patients was the weakest. The weakest item of functional support was respondents' sense of the healthcare professionals' care of patients coping with their disease. Background variables associated with perceived social support were gender, marital status, level of formal education, profession, physical activity, duration of coronary heart disease and previous myocardial infarction. Healthcare professionals should pay extra attention to women, single patients, physically inactive patients, those demonstrating a lower level of education, those with a longer duration of CHD, and respondents without previous acute myocardial infarction. Continuum of care and counselling are important to ensure especially among them. This study provides evidence that healthcare professionals should be more aware of the individual needs for social support among patients with coronary heart disease after percutaneous coronary intervention

    It is clear that steps can be taken for heart disease prevention and that counselors must give thought to adapting existing ideas and techniques and to developing and experimenting with new and innovative preventive tactics. Of utmost importance is the belief that behavioral intervention is both warranted and worthwhile. (Author)

    Full Text Available Multivessel coronary spasm resulting to cardiogenic shock and malignant ventricular arrhythmias though rare has been reported in the literature. The disease seems to be more prevalent in Asians. There have been isolated reports of coronary spasm in patients with reactive airway disease. We report the first case of spontaneous multivessel spasm in a male patient with bronchial asthma of Arab ethnicity resulting in acute myocardial infarction complicated by cardiogenic shock, recurrent ventricular arrhythmias, and transient complete heart block. Literature review of similar cases suggests a strong association with bronchial asthma and a more malignant course in patients with reactive airway disease. The role of intracoronary nitroglycerin in proving the diagnosis even in patients in shock on maximal inotropic supports and intra-aortic balloon pump is highlighted and the importance of considering multivessel coronary spasm as a cause for acute coronary syndrome even in patients with conventional risk factors for atherosclerotic coronary artery disease is reinforced in the discussion of this case.

    Fractional flow reserve (FFR) measured during invasive coronary angiography is the gold standard for lesion-specific decisions on coronary revascularization in patients with stable coronary artery disease (CAD). Current guidelines recommend non-invasive functional or anatomic testing as a gatekeeper to the catheterization laboratory. However, the ''holy grail'' in non-invasive testing of CAD is to establish a single test that quantifies both coronary lesion severity and the associated ischemia. Most evidence to date of such a test is based on the addition of computational analysis of FFR to the anatomic information obtained from standard-acquired coronary CTA data sets at rest (FFR{sub CT}). This review summarizes the clinical evidence for the use of FFR{sub CT} in stable CAD in context to the diagnostic performance of other non-invasive testing modalities. (orig.)

    Objective Increasing evidence suggests epidemiological and pathological links between Alzheimer's disease (AD) and ischemic stroke (IS). We investigated the evidence that shared genetic factors underpin the two diseases. Methods Using genome‐wide association study (GWAS) data from METASTROKE + (15,916 IS cases and 68,826 controls) and the International Genomics of Alzheimer's Project (IGAP; 17,008 AD cases and 37,154 controls), we evaluated known associations with AD and IS. On the subset of data for which we could obtain compatible genotype‐level data (4,610 IS cases, 1,281 AD cases, and 14,320 controls), we estimated the genome‐wide genetic correlation (rG) between AD and IS, and the three subtypes (cardioembolic, small vessel, and large vessel), using genome‐wide single‐nucleotide polymorphism (SNP) data. We then performed a meta‐analysis and pathway analysis in the combined AD and small vessel stroke data sets to identify the SNPs and molecular pathways through which disease risk may be conferred. Results We found evidence of a shared genetic contribution between AD and small vessel stroke (rG [standard error] = 0.37 [0.17]; p = 0.011). Conversely, there was no evidence to support shared genetic factors in AD and IS overall or with the other stroke subtypes. Of the known GWAS associations with IS or AD, none reached significance for association with the other trait (or stroke subtypes). A meta‐analysis of AD IGAP and METASTROKE + small vessel stroke GWAS data highlighted a region (ATP5H/KCTD2/ICT1) associated with both diseases (p = 1.8 × 10−8). A pathway analysis identified four associated pathways involving cholesterol transport and immune response. Interpretation Our findings indicate shared genetic susceptibility to AD and small vessel stroke and highlight potential causal pathways and loci. Ann Neurol 2016;79:739–747 PMID:26913989

    Coronary atherosclerosis without thrombosis is, in general, a benign disease. However, plaque disruption, or fissuring, with superimposed thrombosis, frequently complicates the course of coronary atherosclerosis. Small ruptures often remain clinically silent, whereas more extensive plaque rupture may cause the development of unstable angina, myocardial infarction, and sudden death. The risk of plaque disruption depends more on plaque type (composition) than on plaque size and stenosis severity. Major determinants of a plaque's vulnerability to rupture are: the size and consistency of the lipid-rich atheromatous core; the thickness of the fibrous cap covering the core; and ongoing inflammation and repair within the cap. Both plaque vulnerability (intrinsic disease) and rupture triggers (extrinsic forces) are important for plaque disruption. The former predisposes the plaque to rupture whereas the latter may precipitate it. The resultant thrombotic response, which is important for the clinical presentation and outcome, is portly determined by the reactivity of the circulating platelets and the balance between the fibrinolytic and coagulation systems. New ways of identification and treatment of the dangerous vulnerable plaques responsible for infarction and death, and optimization of antithrombotic treatment, are highly warranted in order to prevent and treat life-threatening coronary thrombosis.

    Full Text Available Coronary artery disease (CAD has become the latest scourge of humankind and referred to in this article as CAD, is the end result of the accumulation of atheromatous plaques within the walls of coronary arteries that supply the myocardium, a process also known as atherosclerosis and manifests mostly in the form of chronic stable angina or acute coronary syndrome. Vitamin D has attracted considerable interest recently due to its role in a number of extraskeletal disease processes including multiple sclerosis, malignancies, diabetes mellitus, and CAD. It is also known as sunshine vitamin due to its production in the body following exposure to ultraviolet rays, and it is a unique vitamin as it acts like a hormone with its receptor present in a wide range of tissues including endothelium, which is the important mediator of atherosclerosis and subsequent CAD. A large number of studies conducted in the past have provided the basic scientific framework and this article attempts to explore the role of Vitamin D deficiency in the pathogenesis of CAD and stresses the need for further research to fill up gap in our knowledge.

    The aims of this study are to determine the prevalence of coronary atherosclerosis in acromegalic patients and to investigate the relationship between the coronary artery calcium score (CS) and acromegaly status and clinical parameters [Framingham risk score (FRS)]. Fifty-six acromegalic patients and paired non-acromegalic volunteers were stratified according to the FRS into low-, intermediate-, and high-risk groups. CS was assessed using multidetector computed tomography. The patients were considered to have controlled or active acromegaly at the time they were submitted to evaluation. Sixty-six percent of acromegalic patients exhibited arterial hypertension, 36 % had diabetes mellitus, and 34 % had hypercholesterolemia. The median FRS and the median risk for cardiovascular event within the next 10 years were similar in the acromegalics and the controls. The median total CS and CS >75th percentile didn't differ significantly between these groups. In patients with controlled acromegaly, a low, intermediate, or high FRS risk was observed in 86, 14, and 0 %, respectively. In patients with active disease, a low, intermediate, or high FRS risk was verified in 94, 3, and 3 %, respectively, and differences between the controlled and active groups were not significant. Seventy-two percent of the patients had total CS = 0, and there were no differences between the controlled and active groups. The risk of coronary artery disease in acromegalic patients, determined according to FRS and CS, is low despite the high prevalence of metabolic abnormalities.

    Full Text Available Matrix metalloproteinases (MMPs play an important role in the pathogenesis of atherosclerosis, the pathology underlying the majority of coronary artery disease (CAD. In this study we tested the hypothesis that polymorphic variation in the MMP genes influences the risk of developing atherosclerosis. We analyzed functional polymorphisms in the promoter of the MMP-1, MMP-3, MMP-9 and MMP-12 genes in 183 Brazilian Caucasian individuals submitted to coronary angiography, of which 67 (37% had normal coronary arteries (control group and 116 (63% had CAD (CAD patient group. The -1607 1G/2G MMP-1, -1171 5A/6A MMP-3, -1562 C/T MMP-9, -82 A/G MMP-12 polymorphisms were analyzed by PCR followed by restriction digestion. No significant differences were observed in allele frequencies between the CAD patients and controls. Haplotype analysis showed no differences between the CAD patients and controls. There was a significant difference in the severity of CAD, as assessed by the number of diseased vessels, in MMP-1 1G/1G homozygous individuals and in those homozygous for the 6A allele of the MMP-3 polymorphism. However, multivariate analysis showed that diabetes mellitus was the only variable independently associated with CAD severity. Our findings indicated that MMP polymorphisms have no significant impact on the risk and severity of CAD.

    Chronic kidney dysfunction is recognized as a risk factor for atherosclerosis and complicates strategies and treatment. Therefore, it is important for cardiologists not only to detect and measure potential kidney dysfunction, but also to know the mechanisms by which the heart and kidney interact, and recognize that in cases of acute coronary syndrome, the presence of renal dysfunction increases the risk of death. The detection and classification of kidney dysfunction into 5 stages is based on the estimated glomerular filtration rate (GFR). The presence of hypertension, endothelial dysfunction, dyslipidemia, inflammation, activation of the renin-angiotensin system and specific calcifications are the main mechanisms by which renal dysfunction can induce or compound cardiovascular disease. The magnitude of renal dysfunction is related to the cardiovascular risk; a linear relation links the extent of GFR decrease and the risk of cardiovascular events. Renal dysfunction and acute coronary syndromes are a dangerous combination: more common comorbidities, more frequent contraindications for effective drugs and higher numbers of drug-related adverse events such as bleeding partially explain the higher mortality in patients with renal dysfunction. In addition, despite higher risk, patients with renal dysfunction often receive fewer guideline-recommended treatments even in the absence of contraindications. Renal dysfunction induces and promotes atherosclerosis by various pathophysiologic pathways and is associated with other cardiovascular risk factors and underuse of appropriate therapy. Therefore, the assessment of renal function is an important step in the risk evaluation of patients with coronary artery disease.

    Introduction The relation between serum rheumatoid factor levels and the extent, severity, and complexity of coronary artery disease has not been adequately studied. Aim Therefore, we assessed the relationship between the severity of coronary artery disease assessed by SYNTAX score and serum rheumatoid factor levels in patients with stable coronary artery disease. Material and methods We enrolled 268 consecutive patients who underwent coronary angiography. Patients with acute coronary syndrome and chronic immune disorders were excluded. Baseline serum rheumatoid factor levels were measured and the SYNTAX score was calculated from the study population. Results Patients were divided into two groups. Group 1 was defined as low SYNTAX score 22. Serum rheumatoid factor levels were significantly higher in the intermediate and high-SYNTAX score group than in the low-SYNTAX score group (16.4 ±9 IU/mlvs. 11.36 ±5 IU/ml, p < 0.001). Also, there was a significant correlation between rheumatoid factor and CRP levels with the SYNTAX score r = 0.411; p < 0.001 and r = 0.275; p < 0.001, respectively. On multivariate linear regression analysis, rheumatoid factor (β = 0.101, p < 0.001) was an independent risk factor for intermediate and high SYNTAX score in patients with stable coronary artery disease. In receiver operator characteristic curve analysis, optimal cut-off value of rheumatoid factor to predict high SYNTAX score was found to be 10.5 IU/ml, with 69% sensitivity and 61% specificity. Conclusions The rheumatoid factor level was independently associated with the extent, complexity, and severity of coronary artery disease assessed by SYNTAX score in patients with stable coronary artery diseases.

    Background and Objective The frequency of multifocal atherosclerosis (MFA) in patients with coronary heart disease (CHD) has not been thoroughly studied. The purpose of our study was to perform ultrasound screening for MFA in patients with coronary atherosclerosis and make evaluation of the sensitivity and significance of different atherosclerosis markers. Methods Using Color Dupplex Ultrasound (CDU), we studied 32 clinically healthy persons and 87 patients of the city of B with clinical data for CHD where we also performed coronarography. Results In patients with coronary atherosclerosis we found high frequency of carotid atherosclerosis (93%) and peripheral artery disease (PAD) (81%). We established verifiable thickening of the intima-media (IMT) of the common carotid artery (CCA) and common femoral artery (CFA) in patients with CHD. There is a correlation between the frequency of carotid and femoral stenoses and CHD proven by coronarography. Patients with CHD had a high relative risk to develop carotid (RR = 5) and peripheral atherosclerosis (RR=3.5) and high frequency of asymptomatic stenoses and thromboses of the internal carotid artery (86.9%) and femoral artery (78.3%), as well as aneurisms of the abdominal aorta (8.1%). Markers for CAD with high sensitivity were the atherosclerotic plaques of ICA (0.93) and CFA (0.81) as well as IMT of the CFA (0.84). Conclusions MFA are common among patients with CHD. Ultrasound diagnosis is the method of choice for simultaneous non-invasive screening of carotid, peripheral and MFA and provides sensitive markers for coronary atherosclerosis. The most sensitive and specific markers for CHD are the combination of the IMT and atherosclerotic plaques of CCA, ICA and CFA (100% sensitivity and 0.92 specificity).

    Full Text Available Coronary artery disease (CAD is defined as obstruction of the lumen of the coronary artery due to formation of atherosclerotic plaque. This eventually leads to reduced blood supply to the heart. It could lead to high morbidity and mortality. Risk factors for CAD are divided into modifiable or non-modifiable. Modifiable such as diabetes, hypertension, hyperlipidemia, obesity, smoking while non-modifiable risks are family history, age, and gender according to previous studies.The aim of this study is to identify the predictors and the prevalence of coronary disease risk factors among young Saudi patients.This study reviewed 1061 patients referred to the cardiac catheterization lab in King Abdulaziz Cardiac Center in Riyadh between the year 2010 and 2013. Included patients were males and females aged 18-45 years who underwent coronary angiography for various clinical indications.The results were divided into two groups; Group A aged 35 years. Male gender in Gp.A 143 (16.1% vs. Gp.B 747 (83.9% p-value = 0.500. Smoking Gp.A 84 (15.8% vs. Gp.B 446 (84.2% p = 0.680. Obesity Gp.A 43 (14.1% vs. Gp.B 262 (85.9% p = 0.234. Family history Gp.A 24 (23.1% vs. 80 (76.9% p = 0.069. Hyperlipidemia Gp.A 40 (12.9% vs. Gp.B 271 (87.1% p = 0.045. Hypertension Gp.A 20 (8.2% vs. Gp 233 (91.8% p = 35 years we found that HTN and Diabetes were statistically significant risk factors. Therefore, a modification of lifestyle habits is recommended.

    Full Text Available Background and Objectives: Anthropometric variables and their relation to conventional coronary artery disease (CAD risk factors in railway employees have been inadequately studied in India. This cross-sectional survey was carried out in the Solapur division of the Central railway in the year 2004, to assess the anthropometric variables in railway employees and their relation to conventional CAD risk factors. Materials and Methods: A total of 995 railway employees, with 872 males and 123 females participated in this cross-sectional study. All subjects underwent anthropometric measurements, fasting lipid profile, and blood sugar level. Various anthropometric indices were calculated for body mass index (BMI, waist circumference (WC, waist-to-hip ratio (WHR, waist-to-height ratio (WHtR, and abdominal volume index (AVI. Statistical analysis was done by EPI Info 6 statistical software. Results: Compared to all other obesity indices, WHtR was most prevalent in both genders. High WHtR was present in 699 (80.16% males and 103 (83.73% females. Age ≥45 years, high systolic BP, high diastolic BP, low HDL, high triglyceride, and diabetes mellitus were positively correlated with high BMI, high WC, high WHR, high WHtR, and high AVI. High BMI, high WC, high WHR, high WHtR, and high AVI were negatively associated with physical inactivity. Conclusions: Over all, anthropometric variables in both genders were significantly deranged in subjects with coronary risk factors. Compared to all other anthropometric variables, WHtR was statistically significantly associated with a majority of coronary artery risk factors. Hence we recommend inclusion of WHtR as a parameter of obesity to predict coronary artery disease risk factor along with WC, WHR, and BMI in epidemiologic studies.

    Renal dysfunction is related to long-term mortality and myocardial infarction after coronary artery bypass grafting (CABG). We aimed to investigate the association between preoperative renal dysfunction and early risk of stroke, myocardial infarction, or heart failure after CABG. From the Swedish Web-system for Enhancement and Development of Evidence-based care in Heart disease Evaluated According to Recommended Therapies registry, we included all 36,284 patients who underwent primary isolated CABG from 2000 to 2008 in Sweden. The Swedish National Inpatient Registry was used to obtain the primary end point, which was rehospitalization for stroke, myocardial infarction, or heart failure ≤90 days after CABG. Logistic regression models were used to estimate the risk for the primary outcome and the secondary outcome of death from any cause, while adjusting for confounders. During 90 days of follow-up, there were 2,462 cardiovascular events and 617 deaths. In total, 17% of patients developed acute kidney injury postoperatively. Odds ratios with 95% confidence intervals for cardiovascular events after adjustment for age, gender, atrial fibrillation, left ventricular ejection fraction, diabetes mellitus, peripheral vascular disease, and history of myocardial infarction, heart failure, or stroke was 1.24 (1.06 to 1.45) in patients with an estimated glomerular filtration rate of 15 to 45 ml/min/1.73 m(2) but became nonsignificant after acute kidney injury was introduced into the statistical model. The risk of death was significantly increased in patients with estimated glomerular filtration rate of 15 to 45 ml/min/1.73 m(2) (odds ratio 1.76, 95% confidence interval 1.38 to 2.25) even after adjustment for all confounders. Renal dysfunction was associated with all-cause mortality but not with cardiovascular events during the first 3 postoperative months after primary isolated CABG.

We measured(1) reactive hyperemia index(RHI) using fingertip peripheral arterial tonometry(RH-PAT Endo-PAT);(2) carotid to femoral pulse wave velocity(PWVc-Complior);(3) augmentation index(AIx), the diastolic area(DAI%) and diastolic reflection area(DRA) of the central aortic pulse wave(Arteriograph);(4) CFR using Doppler echocardiography; and(5) blood levels of lipoprotein-phospholipase A2(LpPLA2).RESULTS: After adjustment for age, sex, blood pressure parameter, lipidemic, diabetic and smoking status, we found that coronary flow reserve was independently related to AIx(b =-0.38, r = 0.009), DAI(b = 0.36, P = 0.014), DRA(b = 0.39, P = 0.005) and RT(b =-0.29,P = 0.026). Additionally, patients with CFR < 2.5 had higher PWVc(11.6 ± 2.3 vs 10.2 ± 1.4 m/s, P = 0.019), SBPc(139.1 ± 17.8 vs 125.2 ± 19.1 mm Hg, P = 0.026), AIx(38.2% ± 14.8% vs 29.4% ± 15.1%, P = 0.011) and lower RHI(1.26 ± 0.28 vs 1.50 ± 0.46, P = 0.012), DAI(44.3% ± 7.9% vs 53.9% ± 6.7%, P = 0.008), DRA(42.2 ± 9.6 vs 51.6 ± 11.4, P = 0.012) and Lp PLA2(268.1 ± 91.9 vs 199.5 ± 78.4 ng/m L, P = 0.002) compared with those with CFR ≥ 2.5. Elevated Lp PLA2 was related with reduced CFR(r =-0.33, P = 0.001), RHI(r =-0.37, P < 0.001) and DRA(r =-0.35, P = 0.001) as well as increased PWVc(r = 0.34, P = 0.012) and AIx(r = 0.34, P = 0.001). CONCLUSION: Abnormal arterial wave reflections are related with impaired coronary flow reserve despite successful revascularization in CAD patients. There is a common inflammatory link between impaired aortic wall properties, endothelial dysfunction and coronary flow impairment in CAD.

    Optical coherence tomography (OCT) is a high-resolution intracoronary arterial imaging modality. We describe 2 patients who were admitted to undergo coronary angiography and OCT for follow-up of Kawasaki disease with coronary artery aneurysms. OCT clearly demonstrated thrombus, stenosis, fibrotic intimal thickening with lamellar calcification, and partial disappearance of the tunica media at the aneurysm site. In addition, focal calcification, intimal thickening, and medial irregularity were observed even in regions of coronary arterial walls that appeared to be normal using coronary angiography. OCT is useful for evaluating coronary arterial sequelae of Kawasaki disease. Copyright © 2014 Canadian Cardiovascular Society. Published by Elsevier Inc. All rights reserved.

    Objective To investigate the clinical applications of coronary CT angiography in patients with suspected coronary artery disease and identify factors that affect CT findings. Methods Medical records of patients suspected of coronary artery disease over a period of 12 months from a tertiary teaching hospital were retrospectively reviewed. Patient age, sex (male/female), duration of symptoms and abnormal rates of coronary CT angiography scans were analysed to investigate the relationship among these parameters. The patients by age were duration of symptoms was also classified into five groups: less than one week, one week to one month, one to three months, three to six months and more than six months. Results Of the 880 patient records reviewed, 800 met the above study criteria. Five hundred and forty nine patients demonstrated abnormal CT findings (68.6%). There was no significant difference in the percentage of abnormal CT findings based on patient sex and the duration of symptoms (P = 0.14). The abnormal rates of coronary CT angiography, however, increased significantly with increasing age (P < 0.001); with patients over 65 years of age 2.5 times more likely to have an abnormal CT scan relative to a patient under 45 years. A significant difference was found between abnormal coronary CT angiography and the duration of symptoms (P = 0.012). Conclusions Our results indicate coronary CT angiography findings are significantly related to the patient age group and duration of symptoms. Clinical referral for coronary CT angiography of patients with suspected coronary artery disease needs to be justified with regard to the judicious use of this imaging modality.

    To determine the relation between left ventricular performance during exercise and the extent of coronary artery disease, the results of exercise radionuclide ventriculography were analyzed in 65 patients who also underwent cardiac catheterization. A scoring system was used to quantitate the extent of coronary artery disease. This system takes into account the number and site of stenoses of the major coronary vessels and their secondary branches. The conventional method of interpreting the coronary angiograms indicated that 26 patients had significant coronary artery disease (defined as 70% or more narrowing of luminal diameter) of one vessel, 21 had multivessel disease and 18 had no significant coronary artery disease. Although the exercise left ventricular ejection fraction was significantly higher in patients with no coronary artery disease than in patients with one or multivessel disease (probability [p] less than 0.001), there was considerable overlap among the three groups. With the scoring system, a good correlation was found between the coronary artery disease score and the exercise left ventricular ejection fraction (r = -0.70; p less than 0.001). If the exercise heart rate was 130 beats/min or greater or the age of the patient was 50 years or less, an even better correlation was found (r = -0.73 and r = -0.82, respectively). The exercise ejection fraction (but not the change in ejection fraction, end-diastolic volume and end-systolic volume from rest to exercise) correlated with the extent of coronary artery disease. The exercise ejection fraction is the most important exercise variable that correlates with the extent of coronary artery disease when the latter is assessed quantitatively by a scoring system rather than the conventional method of reporting coronary angiograms. Young age and greater exercise heart rate strengthened the correlation. The change in ejection fraction from rest to exercise is useful in the diagnosis of coronary artery disease

    The objective of this study is to develop a cost-effectiveness model comparing drug eluting stents(DES) vs bare metal stent(BMS) in patients suffering of stable coronary artery disease. Using a 2-years time horizon, two simulation models have been developed: BMS first line strategy and DES first line strategy. Direct medical costs were estimated considering ambulatory and hospital costs. The effectiveness endpoint was defined as treatment success, which is the absence of major adverse cardiac events. Probabilistic sensitivity analyses were carried out using 10000 Monte-Carlo simulations. DES appeared slightly more efficacious over 2 years(60% of success) when compared to BMS(58% of success). Total costs over 2 years were estimated at 9303  for the DES and at 8926  for bare metal stent. Hence, corresponding mean cost-effectiveness ratios showed slightly lower costs(P < 0.05) per success for the BMS strategy(15520 /success), as compared to the DES strategy(15588 /success). Incremental costeffectiveness ratio is 18850  for one additional percent of success. The sequential strategy including BMS as the first option appears to be slightly less efficacious but more cost-effective compared to the strategy including DES as first option. Future modelling approaches should confirm these results as further comparative data in stable coronary artery disease and long-term evidence become available.

Adenosine and dipyridamole are the most commonly used agents to induce coronary arterial vasodilation for myocardial perfusion imaging. Both cause frequent undesirable side-effects. Because of its ultrashort half-life, adenosine must be administered by constant intravenous infusion during the examination. A key feature of an ideal A2A agonist for myocardial perfusion imaging studies would be an optimal level and duration of hyperemic response. Drugs with a longer half-time and more selective A2A adenosine receptor agonism, such as regadenoson, should theoretically result in a similar degree of coronary vasodilation with fewer or less severe side-effects than non-selective, ultrashort-lasting adenosine receptor stimulation. The available preclinical and clinical data suggest that regadenoson is a highly subtype-selective, potent, low-affinity A2A adenosine receptor agonist that holds promise for future use as a coronary vasodilator in myocardial perfusion imaging studies. Infusion of regadenoson achieves maximum coronary hyperemia that is equivalent to adenosine. After a single bolus infusion over 10 s, hyperemia is maintained significantly longer (approximately 2–5 min than with adenosine, which should facilitate radionuclide distribution for myocardial perfusion imaging studies. In comparison with the clinically competitive A2A adenosine receptor agonist binodenoson, regadenoson has a several-fold shorter duration of action, although the magnitude of hyperemic response is comparable between the two. The more rapid termination of action of regadenoson

    IBD patients are at increased risk of coronary artery disease in the absence of traditional risk factors. However, the disease-related risk factors remain poorly understood although increased inflammation seems to increase cardiovascular disease risk in IBD. Thrombocytes are involved in the pathogenesis of coronary artery disease, and a subset of IBD patients have reactive thrombocytosis. The aim of our study was to investigate the effect of persistent reactive thrombocytosis on the development of coronary artery disease in IBD. We evaluated a retrospective cohort of 2525 IBD patients who were evaluated at the Henry Ford hospital from 2000 to 2004. We performed a case-control study comparing patients with persistent thrombocytosis and patients without persistent thrombocytosis. Cases (n = 36) and controls (n = 72) were matched for age and gender. Coronary artery disease incidence was compared between the two groups. Cases (n = 36) and controls (n = 72) were matched for age and gender. Cases and controls were similar in age at onset of IBD (41.5 vs. 35.5, p value 0.11) and smoking status (33.3 vs. 27.8%, p value 0.66). Persistent thrombocytosis was less common among Caucasian patients (44.44 vs. 62.5%, p value 0.09) and more common in patients who had exposure to steroids during the study follow-up period. Coronary artery disease occurred in 13 (36.1%) patients with persistent thrombocytosis compared to only seven (9.7%) patients in the control group. Persistent reactive thrombocytosis among IBD patients is associated with increased risk of coronary artery disease. Further studies should characterize the clinical and molecular associations of this phenomenon and determine appropriate therapeutic measures.

    The aim of the present study was to explore the effect of adherence to standardized administration of anti-platelet drugs on the prognosis of patients with coronary heart disease. A total of 144 patients newly diagnosed with coronary heart disease at Lu'an Shili Hospital of Anhui Province (Lu'an, China) between June 2010 and June 2012 were followed up. Kaplan-Meier curves and the Cox regression model were used to evaluate the effects of standardized administration of anti-platelet drugs on primary and secondary end-point events. Of the patients with coronary heart disease, 109 (76%) patients took standard anti-platelet drugs following discharge. Kaplan-Meier curve and Cox regression analysis showed that standardized administration of anti-platelet drugs reduced the risk of primary end-point events (including all-cause mortality, non-lethal myocardial infarction and stroke) of patients with coronary heart disease [hazard ratio (HR)=0.307; 95% confidence interval (CI): 0.099-0.953; P=0.041) and all-cause mortality (HR=0.162; 95% CI: 0.029-0.890; P=0.036); however, standardized administration had no predictive value with regard to secondary end-point events. Standardized administration of anti-platelet drugs obviously reduced the risk of primary end-point events in patients with coronary heart disease, and further analysis showed that only all-cause mortality exhibited a statistically significant reduction.

    With the increasing prevalence of obesity, clinicians are now facing a growing population of patients with specific features of clinical presentation, diagnostic challenges, and interventional, medical, and surgical management. After briefly discussing the effect of obesity on atherosclerotic burden in this review, we will focus on strategies clinicians might use to ensure better outcomes when performing revascularization in obese and severely obese patients. These patients tend to present comorbidities at a younger age, and their anthropometric features might limit the use of traditional cardiovascular risk stratification approaches for ischemic disease. Alternative techniques have emerged, especially in nuclear medicine. Positron emission tomography-computed tomography might be the diagnostic imaging technique of choice. When revascularization is considered, features associated with obesity must be considered to guide therapeutic strategies. In percutaneous coronary intervention, a radial approach should be favoured, and adequate antiplatelet therapy with new and more potent agents should be initiated. Weight-based anticoagulation should be contemplated if needed, with the use of drug-eluting stents. An "off-pump" approach for coronary artery bypass grafting might be preferable to the use of cardiopulmonary bypass. For patients who undergo bilateral internal thoracic artery grafting, harvesting using skeletonization might prevent deep sternal wound infections. In contrast to percutaneous coronary intervention, lower surgical bleeding has been observed when lean body mass is used for perioperative heparin dose determination.

    Full Text Available Abstract Background Impaired coronary vasodilation to both endothelial-dependent and endothelial-independent stimuli have been associated with atherosclerosis. Direct measurement of coronary vasodilation using x-ray angiography or intravascular ultrasound is invasive and, thus, not appropriate for asymptomatic patients or for serial follow-up. In this study, high-resolution coronary cardiovascular magnetic resonance (CMR was used to investigate the vasodilatory response to nitroglycerine (NTG of asymptomatic patients at high risk for CAD. Methods A total of 46 asymptomatic subjects were studied: 13 high-risk patients [8 with diabetes mellitus (DM, 5 with end stage renal disease (ESRD] and 33 age-matched controls. Long-axis and cross-sectional coronary artery images were acquired pre- and 5 minutes post-sublingual NTG using a sub-mm-resolution multi-slice spiral coronary CMR sequence. Coronary cross sectional area (CSA was measured on pre- and post-NTG images and % coronary vasodilation was calculated. Results Patients with DM and ESRD had impaired coronary vasodilation to NTG compared to age-matched controls (17.8 ± 7.3% vs. 25.6 ± 7.1%, p = 0.002. This remained significant for ESRD patients alone (14.8 ± 7.7% vs. 25.6 ± 7.1%; p = 0.003 and for DM patients alone (19.8 ± 6.3% vs. 25.6 ± 7.1%; p = 0.049, with a non-significant trend toward greater impairment in the ESRD vs. DM patients (14.8 ± 7.7% vs. 19.8 ± 6.3%; p = 0.23. Conclusion Noninvasive coronary CMR demonstrates impairment of coronary vasodilation to NTG in high-risk patients with DM and ESRD. This may provide a functional indicator of subclinical atherosclerosis and warrants clinical follow up to determine prognostic significance.

    To discover the impact of the various degrees of coronary artery stenosis (CAD) on the left ventricular systolic dysfunction in steady state with quantitative analysis of the regional systolic myocardium in longitudinal, radial and circumferential direction in patients with coronary artery disease by two-dimensional speckle tracking imaging (STI). Forty-three normal wall motion-multi vessel coronary artery disease (NWM-MVD) patients labeled as the experimental groups and forty-two subjects with little risk of CAD marked as the control group were enrolled in this study. The two-dimensional STI was obtained in the apical long axis and three levels of the short axis of the left ventricle. The left ventricular wall was divided into 18 segments. The affected myocardia were divided into three groups: group B (coronary stenosis degree ≤50%), group C (coronary stenosis degree 50%-99%)and group D (coronary stenosis degree ≥99%). Using the Q-analysis software, the longitudinal, radial and circumferential systolic strain (SL, SR, SC) and strain ratio (SrL, SrR, SrC) of the myocardium were analyzed. The bradycardia in the NWM-MVD group is greater than that in the control group (16/43 vs. 7/42, p coronary stenosis degree ≤50%), group C (coronary stenosis degree 50%-99%)and group D (coronary stenosis degree ≥99%), especially the longitudinal and radial systolic function, even though they had normal wall motion. The SrL equaled 1.085 for the cut-off value, and the sums (1.348) of sensitivity (0.673) and specificity (0.675) were the greatest. Bradycardia might be a compensatory mechanism in NWM-MVD patients.

  12. Decreased plasma urotensin Ⅱ levels inversely correlate with extent and severity of coronary artery disease

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Objective To determine the plasma urolensin Ⅱ(UⅡ) levels in various types of coronary heart disease and to clarify how the plasma UⅡ levels correlate with the clinical presentation, extent and severity of coronary artery atherosclerosis (CAD). Methods: One hundred and three aged patients undergoing elective diagnostic coronary angiography for proven or clinical suspected coronary heart disease were enrolled in this study. The extent and severity of coronary artery disease were evaluated by vessel score and Gensini score, respectively. Plasma UⅡ levels were measured by radioimmunoassay. Results: The plasma UⅡ levels in the patients with modest to severe coronary stenosis (3.03±0.34 pg/ml, 1.83±0.67 pg/ml) were significantly lower than that in subjects with normal coronary artery (4.80±1.11 pg/ml, P<0.001). The plasma UⅡ levels in patients with coronary heart disease were also significantly lower than that in patients with insignificant coronary stenosis (P < 0.001). Compared to patients with stable angina pectoris, plasma UⅡ levels in patients with acute coronary syndrome were significantly decreased (1.89±0.51 pg/ml vs 2.42±0.77 pg/ml, P< 0.001). Plasma UⅡ levels were found to be negatively correlated with the severity of coronary artery stenosis (r = -0.488, P<0.001), as well as the vessel score (r = -0.408, P<0.05) in the patients with CAD. Conclusion: Significant inverse correlations exist between the plasma UⅡ levels, and the extent and severity of coronary artery stenosis. These findings suggest that plasma UⅡ contribute to the development and progression of coronary artery stenosis, and may be a novel marker to predict clinical types, as well as the extent and severity of coronary artery disease in the patients.

    Full Text Available BACKGROUND This review covers therapeutic implication of genetic risk variant responsible for coronary artery disease by utilising the highdensity single-nucleotide microarrays to screen the entire human genome. The sequence of the human genome provides the blueprint for life. Approximately, 99.5% of the human genome Deoxyribonucleic Acid (DNA sequence is identical among humans with 0.5% of the genome sequence (15 million bps accounting for all individual differences. MATERIALS AND METHODS The new technology of the computerised chip array of millions of Single-Nucleotide Polymorphisms (SNPs as Deoxyribonucleic Acid (DNA markers makes it possible to study and detect genetic predisposition to common polygenic disorders such as Coronary Artery Disease (CAD. The sample sizes required for these studies are massive and large; worldwide consortiums such as Coronary Artery Disease Genome-wide Replication and Meta-Analysis (CARDIoGRAM study have been formed to accommodate this requirement. After the identification of 9p21 progress to detect genetic predisposition has been remarkable. RESULTS There are currently a total of 50 genetic risk variants predisposing to CAD of genome-wide significance with confirmation in independent populations. Rare variants (Minor Allele Frequency, MAF <5% will require direct sequencing to detect genetic predisposition. CONCLUSION We can develop new biomarkers for detecting early CAD as well as unique targets for novel therapy. The challenge for the future will be to identify the molecular mechanisms mediating the risk of those genetic risk variants that act through nonconventional risk factors. The ultimate objective for the future is the sequencing and functional analysis of the causative polymorphisms for its therapeutic implications.

    This study analyzes the U.S. 2006 Behavioral Risk Factor Surveillance System survey data (N = 235,783) to test whether self-reported cardiovascular disease rates are higher in Appalachian coal mining counties compared to other counties after control for other risks. Dependent variables include self-reported measures of ever (1) being diagnosed with cardiovascular disease (CVD) or with a specific form of CVD including (2) stroke, (3) heart attack, or (4) angina or coronary heart disease (CHD). Independent variables included coal mining, smoking, BMI, drinking, physician supply, diabetes co-morbidity, age, race/ethnicity, education, income, and others. SUDAAN Multilog models were estimated, and odds ratios tested for coal mining effects. After control for covariates, people in Appalachian coal mining areas reported significantly higher risk of CVD (OR = 1.22, 95% CI = 1.14-1.30), angina or CHO (OR = 1.29, 95% C1 = 1.19-1.39) and heart attack (OR = 1.19, 95% C1 = 1.10-1.30). Effects were present for both men and women. Cardiovascular diseases have been linked to both air and water contamination in ways consistent with toxicants found in coal and coal processing. Future research is indicated to assess air and water quality in coal mining communities in Appalachia, with corresponding environmental programs and standards established as indicated.

    Objective To determine whether educational attainment is a causal risk factor in the development of coronary heart disease.Design Mendelian randomisation study, using genetic data as proxies for education to minimise confounding.Setting The main analysis used genetic data from two large consortia (CARDIoGRAMplusC4D and SSGAC), comprising 112 studies from predominantly high income countries. Findings from mendelian randomisation analyses were then compared against results from traditional observational studies (164 170 participants). Finally, genetic data from six additional consortia were analysed to investigate whether longer education can causally alter the common cardiovascular risk factors.Participants The main analysis was of 543 733 men and women (from CARDIoGRAMplusC4D and SSGAC), predominantly of European origin.Exposure A one standard deviation increase in the genetic predisposition towards higher education (3.6 years of additional schooling), measured by 162 genetic variants that have been previously associated with education.Main outcome measure Combined fatal and non-fatal coronary heart disease (63 746 events in CARDIoGRAMplusC4D).Results Genetic predisposition towards 3.6 years of additional education was associated with a one third lower risk of coronary heart disease (odds ratio 0.67, 95% confidence interval 0.59 to 0.77; P=3×10(-8)). This was comparable to findings from traditional observational studies (prevalence odds ratio 0.73, 0.68 to 0.78; incidence odds ratio 0.80, 0.76 to 0.83). Sensitivity analyses were consistent with a causal interpretation in which major bias from genetic pleiotropy was unlikely, although this remains an untestable possibility. Genetic predisposition towards longer education was additionally associated with less smoking, lower body mass index, and a favourable blood lipid profile.Conclusions This mendelian randomisation study found support for the hypothesis that low education is a causal risk factor in the

    Researchers have for many years attempted to establish a relationship between coronary heart disease (CHD) and personality type. In our study, 103 subjects completed Form G of the Myers-Briggs Type Indicator (MBTI). Comparisons were made between 93 CHD patients and an age-appropriate control group (Group C) on each of the four MBTI dimensions: Extraversion-Introversion, Sensing-Intuition, Thinking-Feeling, and Judging-Perceiving. The comparison between CHD patients and Group C showed that CHD patients were significantly more likely to prefer sensing and feeling.

    Using the Patient Learning Style Questionnaire, the author examined differences in perceived learning styles of 125 subjects with coronary artery disease (CAD) for conditions and modes of learning commonly found in patient education. The relation of these preferences to selected personal demographic characteristics was also determined. The results indicate that these subjects most preferred organized, detailed instruction using oral and pictorial-graphic modes of presentation. Independent modes of instruction were less preferred. Additional research on the preferred learning style of CAD patients is needed to enable health professionals involved in CAD patient education to design teaching activities.

    2015-01-01

    Purpose of review The bioactive lysophospholipids, lysophosphatidic acid (LPA) and sphingosine 1 phosphate (S1P) have potent effects on blood and vascular cells. This review focuses their potential contributions to the development of atherosclerosis, acute complications, such as acute myocardial infarction, and chronic ischemic cardiac damage. Recent findings Exciting recent developments have provided insight into the molecular underpinnings of LPA and S1P receptor signaling. New lines of evidence suggest roles for these pathways in the development of atherosclerosis. In experimental animal models, the production, signaling and metabolism of LPA may be influenced by environmental factors in the diet that synergize to promote the progression of atherosclerotic vascular disease. This is supported by observations of human polymorphisms in the lysophospholipid metabolizing enzyme, PPAP2B, that are associated with risk of coronary artery disease and myocardial infarction. S1P signaling protects from myocardial damage that follows acute and chronic ischemia both by direct effects on cardiomyocytes and through stem cell recruitment to ischemic tissue. Summary This review will suggest novel strategies to prevent the complications of coronary artery disease by targeting LPA production and signaling. Additionally, ways in which S1P signaling pathways may be harnessed to attenuate ischemia-induced cardiac dysfunction will be explored. PMID:26270808

    Pulpal inflammation is primarily caused by coronal caries, and leads to root canal therapy (RCT). Chronic inflammation has been associated with various cardiovascular diseases. This study evaluates the association between pulpal inflammation (using RCT as a surrogate) and incident coronary heart disease (CHD). We report results among males from the Health Professionals Follow-Up Study (HPFS), excluding participants with prior cardiovascular disease or diabetes. We obtained RCT data from the HPFS cohort (n = 34,683). Compared to men without RCT, those with >/=1 RCT had a multivariate RR of 1.21 (95% CI 1.05-1.40) for CHD. The association was limited to dentists (RR = 1.38; 95% CI 1.14-1.67). There was no association among nondentists (RR = 1.03). Dental caries was not associated with CHD. The results suggest a possible modest association between pulpal inflammation and CHD.

    The role of vitamin D deficiency in coronary artery disease (CAD) progression is uncertain. Chronic inflammation in epicardial adipose tissue (EAT) has been implicated in the pathogenesis of CAD. However, the molecular mechanism underlying vitamin D deficiency-enhanced inflammation in the EAT of diseased coronary arteries remains unknown. We examined a mechanistic link between 1,25-dihydroxyvitamin D-mediated suppression of nuclear factor-κB (NF-κB) transporter, karyopherin α4 (KPNA4) expression and NF-κB activation in preadipocytes. Furthermore, we determined whether vitamin D deficiency accelerates CAD progression by increasing KPNA4 and nuclear NF-κB levels in EAT. Nuclear protein levels were detected by immunofluorescence and Western blot. Exogenous KPNA4 was transported into cells by a transfection approach and constituted lentiviral vector. Swine were administered vitamin D-deficient or vitamin D-sufficient hypercholesterolemic diet. After 1 year, the histopathology of coronary arteries and nuclear protein expression of EAT were assessed. 1,25-dihydroxyvitamin D inhibited NF-κB activation and reduced KPNA4 levels through increased vitamin D receptor expression. Exogenous KPNA4 rescued 1,25-dihydroxyvitamin D-dependent suppression of NF-κB nuclear translocation and activation. Vitamin D deficiency caused extensive CAD progression and advanced atherosclerotic plaques, which are linked to increased KPNA4 and nuclear NF-κB levels in the EAT. 1,25-dihydroxyvitamin D attenuates NF-κB activation by targeting KPNA4. Vitamin D deficiency accelerates CAD progression at least, in part, through enhanced chronic inflammation of EAT by upregulation of KPNA4, which enhances NF-κB activation. These novel findings provide mechanistic evidence that vitamin D supplementation could be beneficial for the prevention and treatment of CAD. © 2016 American Heart Association, Inc.

    Background: Pseudoexfoliation syndrome (PEX) is recognised by chronic deposition of abnormal pseudoexfoliation material on anterior segment structures of the eye, especially the anterior lens capsule. In recent years, several studies have shown the presence of vascular, cardiac and other organ pseudoexfoliative material in patients with ocular pseudoexfoliation. Aims: The purpose of this study is to determine whether an association exists between ocular pseudoexfoliation and coronary artery disease, aortic aneurysms and peripheric vascular disease. Patients and Methods: 490 patients who underwent coronary angiography (CAG) at Kosuyolu Cardiovascula Research and Training Hospital were included in the study. Patients were evaluated for conventional risk factors such as age, sex, family history, hypertension, diabetes, dislipidemia and smoking. Detailed eye examinations including evaluation of lens were done in all patients. The presence of PEX material in the anterior segment was best appreciated by slit lamp after pupillary dilation. The patients were divided into two groups according to the presence of PEX, and compared for the presence of CAD and other risk factors. Results: CAD was present in 387 patients. 103 patients had normal coronary angiography. 20 (5.2 %) of CAD patients and 4 (3.9%) of normal CAG patients were found to have PEX (p>0.05). There was no significant relationship between CAD and the presence of PEX (p>0.05). When patients were grouped according to the presence of PEX, only age was significantly different between the two groups (r: 0.25, p<0.001). Conclusion: There is no significant relationship between the presence of PEX and CAD. Further studies in larger scales with elderly population may be more valuable. PMID:22558552

    Diabetes mellitus (DM) is an independent risk factor for ischemic stroke. However, controversy exists with regard to the impact of DM on prognosis after ischemic stroke in the Chinese population. We investigated the associations between DM and death, dependency, and stroke recurrence in patients after ischemic stroke onset in a nationwide, prospective registry, the China National Stroke Registry. The China National Stroke Registry consecutively recruited patients hospitalized for acute ischemic stroke in 2007 to 2008 and who were prospectively followed up for clinical and functional outcomes (death, dependency, and stroke recurrence) at 3 and 6 months after disease onset. Multivariable logistic regression was performed to analyze the association between DM and stroke outcomes after adjusting for potential confounding including age, sex, National Institutes of Health Stroke Scale score, glucose level at admission, hypertension, coronary heart disease, smoking, urinary tract infection, and other factors. DM was identified in 3483 (27.0%) of stroke patients. Compared with stroke patients without DM, patients with DM had a significantly higher incidence of death or dependency and of recurrent stroke at 3 and 6 months after stroke onset. DM was an independent risk factor for death or dependency (adjusted odds ratio=1.23; 95% confidence interval, 1.10 to 1.37) in patients with ischemic stroke at 6 months after onset. DM independently predicted poor outcomes in Chinese patients after acute ischemic stroke.

    Full Text Available Objectives Unipolar depression (UPD is a leading cause of global burden of diseases, particularly among the elderly, whose treatment may be challenging. In such cases, ECT is often recommended due to its safety and efficacy. This report presents a case of a 67-year-old male inpatient that developed a rare cardiac complication during ECT. Methods Clinical case report with patient’s consent and bibliographic review. Results A 67-year-old male inpatient with recurrent severe psychotic depression was hospitalized and ECT was indicated after failure of the pharmacological treatment. A comprehensive clinical pre-evaluation revealed only nonspecific ST-segment changes in electrocardiogram. During the 7th ECT session, it was observed transitory ST-segment depression followed by a discrete increase of plasma troponin I. Severe tri-vessel coronary artery stenosis was found and a percutaneous coronary angioplasty was performed, with satisfactory psychiatric and cardiac outcomes. Conclusions Unipolar depression (UPD and cardiovascular disease are often coexistent conditions, especially among the elderly. In the current case, myocardial ischemia was detected lately during ECT therapy and its treatment allowed the UPD treatment to be completed adequately.

    Full Text Available The ear has a reflexive property; therefore, various physical attributes may appear on the auricle when disorders of the internal organs or other parts of the body exist. Auricular diagnostics is an objective, painless, and noninvasive method that provides rapid access to information. Thus, the association between auricular signals and coronary heart disease (CHD should be further investigated. A case control study was conducted to determine the predictive value of auricular signals on 100 cases of CHD (CHD+ve = 50; CHD−ve = 50 via visual inspection, electrical skin resistance measurement, and tenderness testing. The results showed that the presence of an ear lobe crease (ELC was significantly associated with coronary heart disease. The “heart” zone of the CHD+ve group significantly exhibited higher conductivity on both ears than that of the controls. The CHD+ve group experienced significant tenderness in the “heart” region compared with those in the CHD−ve group in both acute and chronic conditions. Further studies that take into consideration the impact of age, race, and earlobe shape on ELC prevalence in a larger sample should be done.

  11. Heart rate reduction in coronary artery disease and heart failure.

    Science.gov (United States)

    Ferrari, Roberto; Fox, Kim

    2016-08-01

    Elevated heart rate is known to induce myocardial ischaemia in patients with coronary artery disease (CAD), and heart rate reduction is a recognized strategy to prevent ischaemic episodes. In addition, clinical evidence shows that slowing the heart rate reduces the symptoms of angina by improving microcirculation and coronary flow. Elevated heart rate is an established risk factor for cardiovascular events in patients with CAD and in those with chronic heart failure (HF). Accordingly, reducing heart rate improves prognosis in patients with HF, as demonstrated in SHIFT. By contrast, data from SIGNIFY indicate that heart rate is not a modifiable risk factor in patients with CAD who do not also have HF. Heart rate is also an important determinant of cardiac arrhythmias; low heart rate can be associated with atrial fibrillation, and high heart rate after exercise can be associated with sudden cardiac death. In this Review, we critically assess these clinical findings, and propose hypotheses for the variable effect of heart rate reduction in cardiovascular disease.

    Mutations in MEF2A have been implicated in an autosomal dominant form of coronary artery disease (adCAD1). In this study we sought to determine whether severe mutations in MEF2A might also explain sporadic cases of coronary artery disease (CAD). To do this, we resequenced the coding sequence and splice sites of MEF2A in {approx}300 patients with premature CAD and failed to find causative mutations in the CAD cohort. However, we did identify the 21 base pair (bp) MEF2A coding sequence deletion originally implicated in adCAD1 in one of 300 elderly control subjects without CAD. Further screening of an additional {approx}1,500 non-CAD patients revealed two more subjects with the MEF2A 21 bp deletion. Genotyping of 19 family members of the three probands with the 21 bp deletion in MEF2A revealed that the mutation did not co-segregate with early CAD. These studies demonstrate that MEF2A mutations are not a common cause of CAD and cast serious doubt on the role of the MEF2A 21 bp deletion in adCAD1.

    Purpose: The authors are developing a computer-aided detection system to assist radiologists in analysis of coronary artery disease in coronary CT angiograms (cCTA). This study evaluated the accuracy of the authors’ coronary artery segmentation and tracking method which are the essential steps to define the search space for the detection of atherosclerotic plaques. Methods: The heart region in cCTA is segmented and the vascular structures are enhanced using the authors’ multiscale coronary artery response (MSCAR) method that performed 3D multiscale filtering and analysis of the eigenvalues of Hessian matrices. Starting from seed points at the origins of the left and right coronary arteries, a 3D rolling balloon region growing (RBG) method that adapts to the local vessel size segmented and tracked each of the coronary arteries and identifies the branches along the tracked vessels. The branches are queued and subsequently tracked until the queue is exhausted. With Institutional Review Board approval, 62 cCTA were collected retrospectively from the authors’ patient files. Three experienced cardiothoracic radiologists manually tracked and marked center points of the coronary arteries as reference standard following the 17-segment model that includes clinically significant coronary arteries. Two radiologists visually examined the computer-segmented vessels and marked the mistakenly tracked veins and noisy structures as false positives (FPs). For the 62 cases, the radiologists marked a total of 10191 center points on 865 visible coronary artery segments. Results: The computer-segmented vessels overlapped with 83.6% (8520/10191) of the center points. Relative to the 865 radiologist-marked segments, the sensitivity reached 91.9% (795/865) if a true positive is defined as a computer-segmented vessel that overlapped with at least 10% of the reference center points marked on the segment. When the overlap threshold is increased to 50% and 100%, the sensitivities were 86

    The aim of this study was to investigate the relationship between established risk factors and segmental localization of coronary artery disease. A total of 2760 patients who underwent coronary angiography were enrolled into the study. Coronary angiographic segmental evaluation was performed according to the scheme of American Heart Association. Patients were classified into 2 groups (group 1: normal coronary artery segments, group 2: coronary artery segments with coronary artery disease). Smoking was highly related with left main coronary artery disease (odds ratio = 7.5; P = .005). Diabetes mellitus and male sex increased the risk of atherosclerosis in all coronary vasculature (odds ratio = 2.7-2.2; P < .001-P < .001). Hypertension was correlated with distal coronary artery (odds ratio = 1.4; P < .001) and family history with distal circumflex lesions (odds ratio = 4.5; P = .005) High triglyceride levels were associated with right coronary artery lesions (odds ratio = 1.00; P =.03). The effect of advanced age was small (odds ratio = 1.08; P < .001). Risk factors may be predictive for segmental localization.

    Mean platelet volume (MPV) is an indicator of platelet activation which is a central process in the pathophysiology of coronary heart disease. The metabolic syndrome (MS) is characterized as the clustering of closely associated and interdependent atherosclerotic risk factors. MS has also been shown to be strongly associated with poor outcome in patients with coronary artery disease (CAD). The present study was designed to investigate MPV values in patients MS and to interrogate the association with CAD. We measured MPV in 205 consecutive patients with metabolic syndrome (mean age, 53+/-7 years) and 140 control subjects without metabolic syndrome (mean age, 52+/-6 years). All patients were selected from individuals who underwent coronary angiography in our hospital with a suspicion of coronary artery disease. To evaluate the severity of coronary artery disease, the patients with MS were subdivided depending upon the coexistence of coronary artery disease: normal coronary arteries, having coronary stenotic lesions of 50%. The MPV was significantly higher in patients with MS than in the control group (10.19+/-1.49 fl vs 8.21+/-1.02 fl, p<0.001). According to the CAD severity, there were no statistically significant differences in MPV among these subgroups. We have shown for the first time that patients with MS have higher MPV compared to control subjects with normal coronary angiograms and to be associated with CAD. Hence MPV can be used as a follow up marker in patients with MS in the point of CAD.

    Full Text Available Introduction & Objective: In modern medicine, researches in behavioural sciences have described link between psychosocial characteristic, specific personality traits, and development of coronary artery disease. The aim of present study was to investigate the relationship between " hostility" and "type A" personality with acute myocardial infarction. Materials & Methods: In this case-control study 102 patients suffering from acute myocardial infarction and 162 no patents individuals after matching by age, gender, education level, marital status and occupation were studied and compared with regard psychological conditions by type A Najarian questionnaire and SCL – 90 – R. Results: Our study found evidence in support of the hypothesis that hostility may predict heart disease more than type A personality.Conclusion: Our study has some practical meaning for prediction and prevention of CHD. This finding suggests that mental health providers should continue to look at the effectiveness of providing psychological intervention for those individuals with high hostility levels.

    Obesity continues to be a growing issue in the United States, with an estimated prevalence of 72 million people. There are major health implications associated with obesity, including its relationship with hypertension, diabetes mellitus type 2, metabolic syndrome, and dyslipidemia, all independent risk factors for coronary artery disease (CAD). Despite the increased risk of developing CAD, in recent years an "obesity paradox" has been described in which moderately obese individuals with established cardiovascular disease, including CAD, appear to have mortality similar to their normal-weight counterparts. This review examines the relationship between obesity and CAD, including the increased risk of hypertension, diabetes mellitus, metabolic syndrome, and dyslipidemia, along with a discussion of the obesity paradox and the benefits of weight reduction.

  9. Reductionism and holism in coronary heart disease and cardiac nursing.

    Chummun, Harry

    Reductionism and holism are two contrasting philosophies which provide scientific knowledge of disease processes, health dynamics and care interventions. While reductionism focuses on specific and perhaps narrow concepts, it enhances our in-depth knowledge of key health issues. Holism focuses on understanding how all the significant factors affecting the particular health issue are involved, so a more informed decision can be made about health intervention. This article explores the contribution each makes to our understanding of coronary heart disease (CHD) and to the preparation of nurses working in cardiac nursing. It proposes that pre- and post-registration nursing curricula reflect both reductionist and holistic approaches and therefore cardiac nurses are suitably trained to manage reductionist as well as holistic care for clients with CHD.

    Full Text Available Coronary artery disease (CAD is a multifactorial disease with environmental and genetic determinants. The genetic determinants of CAD have previously been explored by the candidate gene approach. Recently, the data from the International HapMap Project and the development of dense genotyping chips have enabled us to perform genome-wide association studies (GWAS on a large number of subjects without bias towards any particular candidate genes. In 2007, three chip-based GWAS simultaneously revealed the significant association between common variants on chromosome 9p21 and CAD. This association was replicated among other ethnic groups and also in a meta-analysis. Further investigations have detected several other candidate loci associated with CAD. The chip-based GWAS approach has identified novel and unbiased genetic determinants of CAD and these insights provide the important direction to better understand the pathogenesis of CAD and to develop new and improved preventive measures and treatments for CAD.

    Ischemic heart disease without evidence of obstructive coronary artery disease is a common phenotype comprising different coronary syndromes with either stable or unstable clinical presentation. In this context, the clinical outcome and management appear extremely variable, due to different etiologies. Of note, coronary microvascular dysfunction is the pathogenetic mechanism linking different clinical scenarios in most of the cases. Hence, in this article, we aim to provide a systematic approach of reviewing the prognosis and management of angina or myocardial infarction without evidence of obstructive coronary artery disease. Moreover, we will propose a new scheme of classification by distinguishing between angina with normal coronary artery and myocardial infarction with normal coronary artery in order to facilitate clinicians to perform a proper management workflow.

    To investigate the change and clinical significance of clopidogrel on platelet membrane CD40L in coronary artery disease patients before and after percutaneous coronary intervention (PCI). Methods 30 cases who were diagnosis coronary artery diseases(CAD) by coronary angiography, mean age 56 ± 9 years old. All the patients who had no antiplatelet aggregation contraindication, were treated with standard anti angina pectoris drugs. Before PCI, all the patients took clopidogrel 75 mg per day. Activated platelet membrane CD40L express rate was measured by flow cytometry before and after PCI 6 hours. Results Activated platelet membrane CD40L express rate were 3.73 ± 2.15and 2.46 ± 0.90, respectively in 30 patients before and after PCI 6 hours. Activated platelet membrane CD40L express rate was significantly decrease after PCI 6 hours than that before PCI ( P < 0.01 ). Conclusions Clopidogrel has significance effect on platelet membrane CD40L in coronary artery disease patients undergoing PCI. Clopidogrel can suppression platelet activation and prevent thromboembolism event occurrence.

    Background Coronary artery fistulas (CAFs) are rare congenital abnormality often unintentionally found in patients with coronary artery disease.Clinical diagnosis of CAFs is difficult due to symptomless or lack of specific symptoms.Dual-source computed tomography (DSCT) might be a useful diagnostic tool for CAFs.The study aimed to retrospectively summarize the imaging features of CAFs delineated at DSCT in 48 CAF patients detected from consecutive 6624 patients with suspected or confirmed coronary artery disease in our institution.Methods Forty-eight patients underwent DSCT angiography by using retrospective electrocardiographic (ECG) gating after infusion of 70 ml of intravenous contrast material during breath hold.Maximum intensity projection (MIP),curved planar reconstruction (CPR),and volume rendering technique (VR) were obtained.Anomalous termination of coronary artery in each subject was evaluated by two radiologists (with more than 10 years experience with cardiovascular imaging),and disagreement between diagnosis readers was settled by a consensus reading.Ten of 48 patients also underwent traditional coronary angiography (CAG) simultaneously.Results In each CAF case,DSCT angiography clearly demonstrated the origin,the termination,the size of abnormal vessel and its course in relation to surrounding great vessels.CAF arising from right coronary artery was the most common type,left circumflex was the least one involved among three coronaries,and pulmonary artery was the most common drainage site.Aneurismal fistulous tract,coronary atherosclerosis,myocardial bridging and anomalous origin of coronary artery were also detected in this group.The demonstration of drainage sites in CAG was consistent with DSCT angiography in 9 patients,and judgment on one anomalous connection in CAG was inconsistent with that in DSCT angiography.Conclusions DSCT angiography could provide accurate delineation of anomalous communications,size and numbers of fistulas in patients with

    Patients with obesity and diabetes mellitus are at increased risk for cardiovascular events and have a higher cardiovascular morbidity and mortality. This worse prognosis is partly explained by the late recognition of coronary heart disease in these patients, due to the absence of symptoms. Early identification of coronary heart disease is vital, to initiate preventive medical therapy and improve prognosis. At present, with the use of cardiovascular risk models, the identification of coronary heart disease in these patients remains inadequate. To this end, biomarkers should improve the early identification of patients at increased cardiovascular risk. The first part of this review describes the pathophysiologic pathway from obesity to coronary heart disease. The second part evaluates several mediators from this pathophysiologic pathway for their applicability as biomarkers for the identification of coronary heart disease.

    Stroke is a rare but serious complication of acute coronary syndrome. At present, no specific score exists to identify patients at higher risk. The aim of the present study is to test whether each clinical variable included in the CHA2DS2-VASc score retains its predictive value in patients with recent acute coronary syndrome, irrespective of atrial fibrillation. The meta-analysis was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and Meta-analysis of Observational Studies in Epidemiology (MOOSE) guidelines. All clinical trials and observational studies presenting data on the association between stroke/transient ischemic attack incidence and at least one CHA2DS2-VASc item in patients with a recent acute coronary syndrome were considered in the analysis. Atrial fibrillation diagnosis was also considered. The whole cohort included 558,193 patients of which 7108 (1.3%) had an acute stroke and/or transient ischemic attack during follow-up (median nine months; 1(st)-3(rd) quartile 1-12 months). Age and previous stroke had the highest odds ratios (odds ratio 2.60; 95% confidence interval 2.21-3.06 and odds ratio 2.74; 95% confidence interval 2.19-3.42 respectively), in accordance with the two-point value given in the CHA2DS2-VASc score. All other factors were positively associated with stroke, although with lower odds ratios. Atrial fibrillation, while present in only 11.2% of the population, confirmed its association with an increased risk of stroke and/or transient ischemic attack (odds ratio 2.04; 95% confidence interval 1.71-2.44). All risk factors included in the CHA2DS2-VASc score are associated with stroke/ transient ischemic attack in patients with recent acute coronary syndrome, and retain similar odds ratios to what already seen in atrial fibrillation. The utility of CHA2DS2-VASc score for risk stratification of stroke in patients with acute coronary syndrome remains to be determined. © The European

    Purpose: To prospectively investigate the coronary artery status using coronary CT angiography (CCTA) in patients with Hodgkin lymphoma treated with combined modalities and mediastinal irradiation. Methods and Materials: All consecutive asymptomatic patients with Hodgkin lymphoma entered the study during follow-up, from August 2007 to May 2012. Coronary CT angiography was performed, and risk factors were recorded along with leukocyte telomere length (LTL) measurements. Results: One hundred seventy-nine patients entered the 5-year study. The median follow-up was 11.6 years (range, 2.1-40.2 years), and the median interval between treatment and the CCTA was 9.5 years (range, 0.5-40 years). Coronary artery abnormalities were demonstrated in 46 patients (26%). Coronary CT angiography abnormalities were detected in nearly 15% of the patients within the first 5 years after treatment. A significant increase (34%) occurred 10 years after treatment (P=.05). Stenoses were mostly nonostial. Severe stenoses were observed in 12 (6.7%) of the patients, entailing surgery with either angioplasty with stent placement or bypass grafting in 10 of them (5.5%). A multivariate analysis demonstrated that age at treatment, hypertension, and hypercholesterolemia, as well as radiation dose to the coronary artery origins, were prognostic factors. In the group of patients with LTL measurements, hypertension and LTL were the only independent risk factors. Conclusions: The findings suggest that CCTA can identify asymptomatic individuals at risk of acute coronary artery disease who might require either preventive or curative measures. Conventional risk factors and the radiation dose to coronary artery origins were independent prognostic factors. The prognostic value of LTL needs further investigation.

    There are known clinical and laboratory predictors for stroke and death following CABG. The aim of this study was to determine if transthoracic echocardiographic findings prior to CABG have additional predictive value for occurrence of perioperative cerebrovascular accident (CVA) and death. The files of patients who underwent CABG between January 2002 and November 2004, with perioperative echocardiographic assessment were reviewed. Echocardiographic variables examined included LV size, function and hypertrophy, mitral annulus calcification (MAC) and aortic valve calcification (AVC). Patients in whom post-CABG stroke or death was documented were compared with those without these endpoints. Of the 572 patients who met the study criteria, 33 (5.8%) had a neurological event and 26 (4.5%) died, four after a major stroke. One hundred and sixty-seven patients had MAC and 228 AVC. On multivariate analysis, risk factors for stroke were previous stroke (OR=2.91 CI 1.179-7.24; PMAC with stroke, although death was slightly increased in patients with MAC (44% vs. 29.2%, P=0.114).

    Background The hybrid procedure for coronary heart disease combines minimally invasive coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) and is an alternative to revascularization treatment.We sought to assess the predictive value of four risk-stratification models for risk assessment of major adverse cardiac and cerebrovascular events (MACCE) in patients with multivessel disease undergoing hybrid coronary revascularization.Methods The data of 120 patients were retrospectively collected and the SYNTAX score,EuroSCORE,SinoSCORE and the Global Risk Classification (GRC) calculated for each patient.The outcomes of interest were 2.7-year incidences of MACCE,including death,myocardial infarction,stroke,and any-vessel revascularization.Results During a mean of 2.7-year follow-up,actuarial survival was 99.17%,and no myocardial infarctions occurred.The discriminatory power (area under curve (AUC)) of the SYNTAX score,EuroSCORE,SinoSCORE and GRC for 2.7-year MACCE was 0.60 (95% confidence interval 0.42-0.77),0.65 (0.47-0.82),0.57 (0.39-0.75) and 0.65 (0.46-0.83),respectively.The calibration characteristics of the SYNTAX score,EuroSCORE,SinoSCORE and GRC were 3.92 (P=0.86),5.39 (P=0.37),13.81 (P=0.32) and 0.02 (P=0.89),respectively.Conclusions In patients with multivessel disease undergoing a hybrid procedure,the SYNTAX score,EuroSCORE,SinoSCORE and GRC were inaccurate in predicting MACCE.Modifying risk-stratification models to improve the predictive value for a hybrid procedure is needed.

    Observational studies evaluating the possible interaction between proton pump inhibitors (PPIs) and clopidogrel have shown mixed results. We conducted a systematic review comparing the safety of individual PPIs in patients with coronary artery disease taking clopidogrel. Studies performed from January 1995 to December 2013 were screened for inclusion. Data were extracted, and study quality was graded for 34 potential studies. For those studies in which follow-up period, outcomes, and multivariable adjustment were comparable, meta-analysis was performed.The adjusted odds or hazard ratios for the composite of cardiovascular or all-cause death, myocardial infarction, and stroke at 1 year were reported in 6 observational studies with data on individual PPIs. Random-effects meta-analyses of the 6 studies revealed an increased risk for adverse cardiovascular events for those taking pantoprazole (hazard ratio 1.38; 95% CI 1.12-1.70), lansoprazole (hazard ratio 1.29; 95% CI 1.09-1.52), or esomeprazole (hazard ratio 1.27; 95% CI 1.02-1.58) compared with patients on no PPI. This association was not significant for omeprazole (hazard ratio 1.16; 95% CI 0.93-1.44). Sensitivity analyses for the coronary artery disease population (acute coronary syndrome versus mixed) and exclusion of a single study due to heterogeneity of reported results did not have significant influence on the effect estimates for any PPIs. Several frequently used PPIs previously thought to be safe for concomitant use with clopidogrel were associated with greater risk of adverse cardiovascular events. Although the data are observational, they highlight the need for randomized controlled trials to evaluate the safety of concomitant PPI and clopidogrel use in patients with coronary artery disease. © 2015 The Authors.

    Kawasaki disease (KD) is a serious pediatric illness affecting the cardiovascular system. One of the most serious complications of KD, occurring in about 25% of untreated cases, is the formation of large aneurysms in the coronary arteries, which put patients at risk for myocardial infarction. In this project we performed patient specific computational simulations of blood flow in aneurysmal left and right coronary arteries of a KD patient to gain an understanding about their hemodynamics. Models were constructed from CT data using custom software. Typical pulsatile flow waveforms were applied at the model inlets, while resistance and RCR lumped models were applied and compared at the outlets. Simulated pressure waveforms compared well with typical physiologic data. High wall shear stress values are found in the narrow region at the base of the aneurysm and low shear values occur in regions of recirculation. A Lagrangian approach has been adopted to perform particle tracking and compute particle residence time in the recirculation. Our long-term goal will be to develop links between hemodynamics and the risk for thrombus formation in order to assist in clinical decision-making.

    2015-01-01

    Obesity used to be among the more neglected public health problems, but has unfolded as a growing medical and socioeconomic burden of epidemic proportions. Morbid obesity is linked to traditional cardiovascular risk factors like, hypertension, hyperlipidemia and diabetes, and suspected to incur increased morbidity and mortality in the Western and even third world populations. This patient cohort is also at greater risk to develop coronary artery disease. Recent population-based registries revealed that 43% and 24% of all cases of coronary revascularization were carried out in overweight and obese patients, respectively. However, despite evidence of a positive correlation between obesity and increased cardiovascular morbidity, some authors have described a better clinical outcome in overweight and obese patients, a phenomenon they coined “obesity paradoxon”. Thus, there is an ongoing debate in light of conflicting data and the possibility of confounding bias causing misconception and challenging the “obesity paradox”.

    Obesity used to be among the more neglected public health problems, but has unfolded as a growing medical and socioeconomic burden of epidemic proportions. Morbid obesity is linked to traditional cardiovascular risk factors like, hypertension, hyperlipidemia and diabetes, and suspected to incur increased morbidity and mortality in the Western and even third world populations. This patient cohort is also at greater risk to develop coronary artery disease. Recent population-based registries revealed that 43% and 24% of all cases of coronary revascularization were carried out in overweight and obese patients, respectively. However, despite evidence of a positive correlation between obesity and increased cardiovascular morbidity, some authors have described a better clinical outcome in overweight and obese patients, a phenomenon they coined "obesity paradoxon". Thus, there is an ongoing debate in light of conflicting data and the possibility of confounding bias causing misconception and challenging the "obesity paradox".

    Full Text Available Purpose: Previous studies comparing percutaneous coronary intervention (PCI with coronary artery bypass graft surgery (CABG in patients with unprotected left main or three-vessel coronary artery disease (LM-3VD have excluded patients at high surgical risk. We compared clinical outcomes after PCI with drug-eluting stents to CABG in high surgical risk patients with LM-3VD. Methods: Patients with symptomatic LM-3VD who had Society of Thoracic Surgeons (STS-predicted operative mortality > 5% and were undergoing either PCI with drug-eluting stents or CABG at a tertiary care center from January 2009 to December 2010 were enrolled in this nonrandomized prospective study. Results: Mean STS score was 14.5 ± 5.8% for PCI (n=83 vs. 13.6 ± 7.1% for CABG (n=187 (P=0.31. After mean follow-up of 37 months, incidence of the composite primary endpoint (death, myocardial infarction or stroke was 42.2% for PCI and 39.6% for CABG (P=0.69, hazard ratio 1.3, 95% confidence interval 0.5-2.8. There were no differences in the individual components of the primary endpoint between PCI and CABG. Repeat revascularization was 30.1% for PCI vs. 9.6% for CABG (P=0.001. Major adverse cardiac and cerebrovascular event rates were similar between PCI and CABG, 50.6% vs. 42.2%, respectively (P=0.23. Patients in the PCI group were less likely than those in the CABG group to be discharged to a nursing home (12.1% vs. 47.1%, P 5%.

    The purpose of this study is to identify patterns of illness perception in patients with angiografically verified Coronary Artery Disease. A total of 166 patients (age: 64.4 ± 12.1, 80.7% male) were recruited after angiography. Cluster analysis on the items of the Brief Illness Perception Questionnaire was used to identify patterns of illness perception. The resulting groups were characterized with regard to Quality of Life (MacNew), anxiety and depression (GAD-7 and PHQ-9) and resilience (RS-13). The analysis revealed 4 distinct groups differing with regard to the items covering the perception of the physical and emotional impact of disease. Stronger perceptions in these domains were associated with lower Health Related Quality of Life and higher levels of emotional distress. Group 1 (33.1%) reported the strongest perceptions of the physical and emotional impact of disease and expressed low treatment control, high chronic timeline and significantly higher levels of depression than the other groups. Group 2 (27.7%) was characterized by more moderate perceptions of the emotional and physical impact of disease together with low scores on illness coherence and chronic timeline. Groups 3 (25.3%) and 4 (13.9%) reported smaller physical and emotional impact of illness but differed in chronic timeline. Our results correspond largely to recent findings in patients with other chronic diseases. Further research is needed to explore if stratification of patients according patterns of illness perception can help to inform patient-physician communication strategies.

    Full Text Available Objective: The relationship between psychological factors and cardiac diseases has been concerned for a long but our knowledge about the cognitive profiles which could be important etiological factor in cardiac disease and comorbid psychiatric disorders is limited. In this study, we aimed to compare the cognitive profiles of coronary artery disease patients with or without comorbid anxiety disorder. Method: A total of 35 coronary artery disease patients with anxiety disorder and 20 coronary artery disease patients without comorbid anxiety disorders were enrolled into the study. Beck Anxiety Inventory and the Young Schema Questionnaire-Short Form 3 were applied to each participant. Results: Disconnection, rejection, impaired autonomy self-manifestation, extreme vigilance, unrelenting standards, other-directedness, and impaired limits schema domain scores were significantly higher in coronary artery disease patients with anxiety disorder comorbidity compared to coronary artery disease patients without anxiety disorder. Conclusion: Our study has revealed significant differences in cognitive profiles of coronary artery disease patients with comorbidity of anxiety disorders. These findings show the importance of cognitive profiles which were observed in coronary artery disease patients with anxiety disorders. Schema-focused approach might be useful in the treatment of such patients. Further studies with schema-focused therapy approaches are needed to illustrate the issue.

    We present a case of coronary ectasia and LAD coronary artery aneurysm with angiographic characteristics of Kawasaki disease in a three-yr-old girl two-yr status post-orthotopic heart transplant. Coronary anomalies were noted during initial screening coronary angiography two yr after transplant. Subsequent review of the donor echocardiogram revealed that the LMCA had been mildly dilated prior to transplant. In the absence of any symptoms consistent with Kawasaki disease in the transplant recipient, this appears to be a case of Kawasaki disease in the organ donor manifesting with coronary anomalies in the transplant recipient. The patient has done well clinically, and repeat coronary angiography has revealed partial regression of coronary anomalies. Given multiple reports in the literature of persistent abnormalities of coronary artery morphology and function after Kawasaki disease, close monitoring is warranted, with consideration of potential coronary protective medical therapies. © 2012 John Wiley & Sons A/S.

    Type 2 diabetes mellitus and pre-diabetes are risk factors for atherosclerosis and are highly prevalent in patients with coronary artery disease. However, the prevalence of impaired glucose metabolism in patients with peripheral artery disease is not as well elucidated. We aimed at comparing prevalence rates of type 2 diabetes mellitus and pre-diabetes, which were diagnosed according to the current American Diabetes Association criteria, among 364 patients with peripheral artery disease, 529 patients with coronary artery disease and 383 controls. The prevalence of type 2 diabetes mellitus in peripheral artery disease patients was 49.7%. It was significantly higher in these patients than in coronary artery disease patients (34.4%; p disease group with the coronary artery disease group (p disease group with controls (p prevalence of pre-diabetes among non-diabetic subjects was high in all three study groups (64.5% in peripheral artery disease patients, 63.4% in coronary artery disease patients and 61.8% in controls), without significant between-group differences. In conclusion, the prevalence of type 2 diabetes mellitus is even higher in peripheral artery disease patients than in coronary artery disease patients. This observation underlines the need to consider impaired glucose regulation in the management of peripheral artery disease.

    Full Text Available Sickle Cell Disease(SCD is one of the most common hemoglobinopathies in the world which causes stroke. The management of stroke depends on the manifestations and the age of the patient. Especially in childhood, anatomic and physiological abnormalities of CNS may be a predisposing factors. Stroke mostly affects the distal segments of the Internal Carotid Artery, but also middle and anterior segments of the cerebral arteries are involved. The most important predisposing factors are the arterial malformations, stenosis and obstructions in cranial arteries, generally involving Internal Carotid Artery, frequently Proximal Middle Cerebral or Anterior Cerebral Arteries. After infarcts at brain vessels, most frequent clinical findings are hemiparesis or hemiplegia, impaired speech, focal seizures, gait disturbances. Risk factors for predisposing stroke are prior transient ischemia, baseline Hb decrease, acute chest sydrome within previous two weeks, systolic blood pressure rises, leucocyte increases. The patient with silent stroke or transient ischemic attacks may be asymptomatic or without neurological symptoms. Neuroimaging abnormalities may be seen without significant clinical findings in children with SCD. We talk about silent stroke if there are neuroradiological abnormalities without clinical findings. Children with silent strokes are more prone to new strokes. If there is a significant stroke a ischemic stroke often present with focal neurological signs and symptoms. If patient is asymptomatic or have suspected stroke, first step may be performance of Transcranial Doppler Ultrasonography (TCD. Children with time-averaged mean velocity (TAMV, measured in Middle Carotid Artery or in distal internal carotid Artery abnormally elevated, defined as TAMV≥200cm/sec, have sixfold increase for stroke than those with normal TAMV≤170cm/sec. For these patients under the risk of stroke, chronic blood transfusion is recommended for prevention of primary

    The goal of this research is to analyze the differences in recovery of walk of two groups of patients who have suffered the stroke--those who have and have not suffered from heart disease prior to the stroke. Test group consisted of patients who have suffered the stroke, and have been rehabilitated in the Clinic for physical medicine and rehabilitation in Tuzla, in 2003. Patients who have had a heart disease before suffering the stroke and have been treated by a cardiologist comprised the first test group (Group I, N=48), while patients without previous heart disease comprised the second test group (Group II, N=69). In relation to their ability to walk, patients have been divided into three groups: those who are able to walk without help, those who are not able to walk and those who are able to walk with a walking aid. Therapies used include kinesiotherapy, paraffin, criotherapy, and electro procedures. Total number of those rehabilitated in the hospital after the stroke is 117, out of which 45 (38.5 %) were women and 72 (61.5 %) men, with average of 68 +/- 9,2 years of age. According to the kind of stroke suffered, 105 patients have had ischemia (89.7 %) and 12 have had hemorrhagia (10.3 %). The highest number of patients have had paralysis of the left side of the body--48 (41.0 %), then paralysis of the right side--43 (36.8 %) and both sides--15 (12.8 %). In relation to the localization of the changes in the brain detected in the CT, the highest number of patients have had multiply lacunar changes--41 (35,0 %), then changes in parietal area--33 (28.2 %) and temporoparietal area--22 (18.8 %), and a bit less had changes in capsula interna--15 (12.8 %), occipital--3 (2.6 %) and cerebellum--3 (2.6 %). In relation to the heart diseases, most of the patients have had compensated weakness of the heart--20 (41.7 %), suffered infarctus myocardii--8 (16.7 %) and atrial fibrillation--8 (16.7 %), with angina pectoris 6 (12,5 %), with arrhitmia--3 (6.3 %) and heart surgery--3

  17. The rarity of coronary heart disease in South African blacks.

    Coronary heart disease (CHD) remains an uncommon disorder in the South African Black population. It has been suggested that herein lies an enigma, since it is believed that these people are considerably exposed to the conventional risk factors for CHD. To test this belief I have assessed the exposure of Black people, in time and degree, to the following CHD risk factors: affluence, age, hypertension, hyperlipidaemia, dietary excess, smoking, physical inactivity, diabetes, obesity, hyperuricaemia and hyperinsulinism. Among males only hypertension, and among females only hypertension and obesity, emerged as prominent factors. However, neither of these is significantly atherogenic in the social, nutritional and metabolic milieu in which Blacks generally live, and obesity is a doubtful atherogenic factor, even in westernized populations. It is therefore concluded that the rarity of CHD in Blacks is not enigmatic, but is appropriate to their environmental circumstances.

    Dietary intake of both saturated and trans fatty acids has been associated with an increase in the risk of coronary heart disease (CHD). Evidence comes mainly from controlled dietary experiments with intermediate end points, such as blood lipoproteins, and from observational studies. A few small, randomized controlled trials with clinical end points have been carried out in which saturated fat was replaced with polyunsaturated fat, leading to a reduction in low-density lipoprotein cholesterol and a reduction in CHD risk. However, no such studies exist for trans fatty acids. More high-quality, randomized controlled trials on fatty acids and CHD are required, but public health recommendations to reduce intake of both saturated and trans fatty acids are appropriate based on the current evidence.

    There are a wide variety of coronary artery anomalies and disease in adults with congenital heart disease (CHD). In fact, the increasing burden of acquired coronary artery disease (CAD) has to be considered in addition to congenital abnormalities of the coronary arteries, isolated or associated to other congenital diseases. This is largely a consequence of the increasing number of patients reaching older age. Due to complex underlying cardiac anatomy, previous surgery and comorbidities, treatment can be challenging. Individualized and multidisciplinary management involving congenital heart cardiologists, cardiac surgeons, coronary interventionists and imaging specialists is essential. This review gives an overview of coronary artery involvement in adults with CHD, summarizes the current literature and focuses on prevention, diagnosis and treatment. The potential role of cardiovascular risk factors for CAD is also discussed.
