    In patients with coronary heart disease anxiety is often overlooked. Symptoms of anxiety are often similar to coronary heart disease symptoms. The prevalence of anxiety in general population and coronary heart disease patients is very high. While the underlying pathophysiology of the connection remains unclear, anxiety lowers the quality of life and is a factor for a higher risk of morbidity and mortality due to coronary heart disease.

    The relationships between two behavioral patterns, cardiac risk factors, and coronary heart disease are investigated. Risk factors used in the analysis were family history of coronary disease, smoking, cholesterol, obesity, systotic blood pressure, diastolic blood pressure, blood sugar, uric acid, erythrocyte sedimentation rate, and white blood unit. It was found that conventional, non-behavioral pattern risk factors alone were not significantly related to coronary heart disease.

    Coronary heart disease is the leading cause of death worldwide and accounts for 13.7% of deaths in countries like Pakistan. Its association with stress has not been well considered in our setup. Patients with coronary artery disease admitted for coronary artery bypass grafting may have a high prevalence of stress that might increase the risk of adverse outcomes. 60 patients with coronary artery disease admitted to the Civil Hospital Karachi for coronary artery bypass graft surgery from January 1 to March 31, 2012, were evaluated using a stress evaluation scale. Stress of varying degrees was found to be a significant independent risk factor in patients with coronary heart disease. Analysis of our collected sample of patients with stress showed 60% with high stress (p = 0.025) and 36.7% moderate stress (p = 0.0025). An appreciable relationship was found between stress and patient age, sex, body mass index, blood group, and the incidence of myocardial infarction. Our study found evidence of an independent causative association between psychological stress and coronary heart disease, of a similar order to the more conventional coronary heart disease risk factors.

    Coronary heart disease and the risk factors which predispose to it aggregate in families. How much of this clustering of disease is "explained" by the familial resemblance in predisposing factors? The published reports which bear on this question fall into six distinct study designs: prospective studies, persons at high or low risk or persons with and without a positive family history as points of departure, case-control studies, studies of patients who had a coronary angiogram and studies in different ethnic groups. The findings of the 16 investigations reviewed suggest that there are as yet unidentified factors - genetic, environmental or both - which are responsible for familial clustering of coronary heart disease, apart from the three main risk factors (serum lipids, blood pressure, smoking) and diabetes. Future research must put greater emphasis on studies of families rather than individuals and on closer collaboration between epidemiologists and geneticists, in order to fill these gaps in knowledge. It is likely that the individual predisposition to coronary heart disease is due in part to genetic influences which remain to be discovered in the course of such studies. They would help in identifying susceptible person in the population with greater precision than is now possible. The "high-risk strategy" of coronary heart disease prevention will become more efficient as more specific and sensitive tests of disease prediction are developed. In the meantime, preventive programmes must be put into action on the basis of what is already known, on the level of both the high-risk and the community-wide mass strategy.

    Aim of the present study was to determine the prevalence of coronary artery anomalies in children with congenital heart disease. Data of 1138 consecutive patients who were referred for cardiac catheterization and angiography for assessment of coronary anomaly between January 2005 and December 2009 were retrospectively analyzed. Total of 515 patients whose coronary arteries could be examined through left ventricle and aortic root injection were included in the study. Of 515 angiograms with visible coronaries, 42 patients (20 males, 22 females; mean age: 5.3±2.0 years) were found to have final diagnosis of coronary anomaly. Prevalence of coronary artery anomalies was 8.16% in this study. It was determined that 38 (90.4%) were anomalies of origination, 2 (4.8%) were anomalies of intrinsic coronary arterial anatomy, and 2 (4.8%) were anomalies of coronary termination. Most common coronary artery abnormality was anomalous origin of the right coronary artery from the left aortic sinus (16 patients; 38.1%), and the most common congenital heart disease was tetralogy of Fallot (18 patients; 42.9%). Recognizing variability of coronary artery anomalies is critical when considering surgical or interventional therapies in children with congenital heart disease.

    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.

    2017-03-01

    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.

    Coronary artery disease is the leading cause of morbidity and mortality around the world. Autonomic nervous system abnormalities are associated with coronary artery disease and its complications. Exercise stress tests are routinely used for the detection of the presence of coronary artery disease. In this study, we observed the association between heart rate profile during exercise and the severity of coronary artery disease. One hundred and sixty patients with abnormal exercise treadmill test (> or =1 mm horizontal or downsloping ST-segment depression; 119 men, 41 women; mean age = 57 +/- 9 years) were included in the study. Use of any drug affecting heart rate was not permitted. Resting heart rate before exercise, maximum heart rate during exercise, and resting heart rate after exercise (5 min later) were measured and two parameters were calculated: heart rate increment (maximum heart rate - resting heart rate before exercise) and heart rate decrement (maximum heart rate - resting heart rate after exercise). All patients underwent selective coronary angiography and subclassified into two groups according to stenotic lesion severity. Group 1 had at least 50% of stenotic lesion and group 2 had less than 50%. Patients in the first group had increased resting heart rate, decreased maximum heart rate, decreased heart rate increment, and decreased heart rate decrement compared with second group. All patients were classified into tertiles of resting heart rate, heart rate increment, and heart rate decrement level to evaluate whether these parameters were associated with severity of coronary artery stenosis in the study. The multiple-adjusted odds ratio of the risk of severe coronary atherosclerosis was 21.888 (95% confidence interval 6.983-68.606) for the highest tertile of resting heart rate level compared with the lowest tertile. In addition, the multiple-adjusted odds ratio of the risk of severe coronary atherosclerosis was 20.987 (95% confidence interval 6

    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. .

    2015-02-01

    Many patients with angina and signs of myocardial ischemia on stress testing have no significant obstructive epicardial coronary disease. There are many potential coronary and non-coronary mechanisms for ischemia without obstructive epicardial coronary disease, and prominent among these is coronary microvascular and/or endothelial dysfunction. Patients with coronary microvascular and/or endothelial dysfunction are often at increased risk of adverse cardiovascular events, including ischemic events and heart failure despite preserved ventricular systolic function. In this article, we will review the diagnosis and treatment of coronary microvascular and endothelial dysfunction, discuss their potential contribution to heart failure with preserved ejection fraction, and highlight recent advances in the evaluation of atherosclerotic morphology in these patients, many of whom have non-obstructive epicardial disease.

    Coronary heart disease (CHD) is the most common cause of death globally, although mortality rates are falling. Psychological symptoms are prevalent for people with CHD, and many psychological treatments are offered following cardiac events or procedures with the aim of improving health and outcomes. This is an update of a Cochrane systematic review previously published in 2011. To assess the effectiveness of psychological interventions (alone or with cardiac rehabilitation) compared with usual care (including cardiac rehabilitation where available) for people with CHD on total mortality and cardiac mortality; cardiac morbidity; and participant-reported psychological outcomes of levels of depression, anxiety, and stress; and to explore potential study-level predictors of the effectiveness of psychological interventions in this population. We updated the previous Cochrane Review searches by searching the following databases on 27 April 2016: CENTRAL in the Cochrane Library, MEDLINE (Ovid), Embase (Ovid), PsycINFO (Ovid), and CINAHL (EBSCO). We included randomised controlled trials (RCTs) of psychological interventions compared to usual care, administered by trained staff, and delivered to adults with a specific diagnosis of CHD. We selected only studies estimating the independent effect of the psychological component, and with a minimum follow-up of six months. The study population comprised of adults after: a myocardial infarction (MI), a revascularisation procedure (coronary artery bypass graft (CABG) or percutaneous coronary intervention (PCI)), and adults with angina or angiographically defined coronary artery disease (CAD). RCTs had to report at least one of the following outcomes: mortality (total- or cardiac-related); cardiac morbidity (MI, revascularisation procedures); or participant-reported levels of depression, anxiety, or stress. Two review authors independently screened titles and abstracts of all references for eligibility. A lead review author

    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

    Objective: To discuss the incidence and clinical predictors of radial artery spasm occurred in performing transradial coronary intervention for coronary heart disease. Methods: A total of 1020 patients, who underwent transradial coronary procedures for coronary heart disease during the period of May 2007 Jan 2010 in authors' hospital, were enrolled in this study. All clinical information and medication were recorded in detail. Arteriography via radial artery was performed in all patients. The diameter of the radial artery as well as the arterial anatomy, including arterial variations, were determined and observed, which was follow by coronary angiography or percutaneous coronary intervention. Multivariate Logistic regression analysis was adopted to evaluate the variables, such as clinical parameters, angiographic characteristics of the radial artery and procedure-related factors, in predicting the occurrence of radial artery spasm. Results: Radial artery spasm occurred in 209 (20.5%) patients. Multivariate Logistic regression analysis showed that the following eight factors were independently associated with the occurrence of radial artery spasm. These factors were as follows: female gender (OR=2.8, 95% CI 2.5-5.8; P=0.001), age (OR=0.68, 95% CI 0.60-0.92; P=0.003), smoking (OR=2.3, 95% CI 1.8-4.1; P=0.026), moderate-to-severe pain of forearm during radial artery cannulation (OR=3.0, 95% CI 2.3-4.8; P=0.006), radial artery anatomical abnormalities (OR=4.7, 95% CI 3.6-7.2; P=0.002), the ratio of radial artery diameter to patient's height (RAH) (OR=5.2, 95% CI 3.7-8.1; P=0.012), the ratio of radial artery diameter to outer diameter of the sheath (RAOD) (OR=5.8, 95% CI 4.2-6.9; P=0.006) and the number of catheter exchange (OR=2.3, 95% CI 1.4-4.3; P=0.038).

    The authors determined the independent influence of coronary hyperperfusion on myocardial metabolism in isolated and intact hearts. In an isovolumic blood-perfused rat heart preparation working against a left ventricular (LV) balloon, the effect of increasing coronary perfusion pressure from 100 to 150 mmHg was assessed. They concluded that coronary hyperperfusion was not an independent stimulus to myocardial VO 2 . To further test this, the effect of coronary hyperperfusion on myocardial metabolism was studied in an intact working swine heart preparation where the cardiac output was fixed with a right heart bypass circuit. Fatty acid oxidation in the left anterior descending bed was assessed by production of 14 CO 2 from [ 14 C(U)]palmitate. They conclude that coronary hyperperfusion is not an independent determinant of myocardial oxidation or fatty acid utilization, and enhancement of mechanical function by the garden-hose effect appears to be dependent on the parameters of LV performance that are controlled

  18. Psychological Stress, Inflammation, and Coronary Heart Disease.

    In this review, we summarize evidence on the risk factor psychological stress in the context of coronary heart disease (CHD) in humans and explore the role of inflammation as a potential underlying mechanism. While chronic stress increases the risk of incident CHD and poor cardiovascular prognosis, acute emotional stress can trigger acute CHD events in vulnerable patients. Evidence supporting a potential role for inflammation as a promising biological mechanism comes from population-based studies showing associations between chronic stress and increased inflammation. Similarly, experimental studies demonstrate acute stress-induced increases in inflammatory markers and suggest modulatory potential for pharmacological and biobehavioral interventions. So far, studies investigating patients with cardiovascular disease are few and the full sequence of events from stress to inflammation to CHD remains to be established. Psychological stress is an independent CHD risk factor associated with increased inflammation. Although promising, causality needs to be further explored.

    Survival of patients with congenital heart defects has improved dramatically. Many will undergo interventional catheter or surgical procedures later in life. Others will develop atherosclerotic or post-surgical coronary heart disease. The coronary artery anatomy in patients with congenital heart disease differs substantially from that seen in the structurally normal heart. This has implications for diagnostic procedures as well as interventions. The unique epicardial course seen in some defects could impair interpretation of coronary angiograms. Interventional procedures, especially at the base of the heart, risk injuring unusually placed coronary arteries so that coronary artery anatomy must be delineated thoroughly prior to the procedure. In this review, we will describe the variants of coronary artery anatomy and their implications for interventional and surgical treatment and for sudden death during late follow-up in several types of congenital heart defects including: tetralogy of Fallot, truncus arteriosus, transposition of the great arteries, double outlet right ventricle, congenitally corrected transposition of the great arteries and defects with functionally one ventricle. We will also discuss the coronary abnormalities seen in Kawasaki disease.

    Despite the progress made in the prevention and treatment of rejection of the transplanted heart, cardiac allograft vasculopathy (CAV) remains the main cause of death in late survival transplanted patients. CAV consists of a progressive diffuse intimal hyperplasia and the proliferation of vascular smooth muscle cells, ending in wall thickening of epicardial vessels, intramyocardial arteries (50-20 μm), arterioles (20-10 μm), and capillaries (system. The non-immunological factors are older donor age, ischemia-reperfusion time, hyperlipidemia and CMV infections. Diagnostic techniques that are able to assess microvascular function are lacking. Intravascular ultrasound and fractional flow reserve, when performed during coronary angiography, are able to detect epicardial coronary artery disease but are not sensitive enough to assess microvascular changes. Some authors have proposed an index of microcirculatory resistance during maximal hyperemia, which is calculated by dividing pressure by flow (distal pressure multiplied by the hyperemic mean transit time). Non-invasive methods to assess coronary physiology are stress echocardiography, coronary flow reserve by transthoracic Doppler echocardiography, single photon emission computed tomography, and perfusion cardiac magnetic resonance. In this review, we intend to analyze the mechanisms, consequences and therapeutic implications of microvascular dysfunction, including an extended citation of relevant literature data.

    Coronary heart disease is the leading cause of death and disability worldwide. Coronary angiography makes it possible to visualize coronary artery stenosis and can be used for angioplasty and stent implantation; however, it does not allow the assessment of changes in myocardial microcirculation. The severity of an angiographically evaluated coronary stenosis does not always correspond to the extent of myocardial ischemia. Nonivasive techniques are needed to reexamine our reliance on coronary angiography and to explore the clinical value fo the physiological assessment of coronary artery stenoses. Such noninvasive techniques might become important tools in the future following an overal evaluation of coronary morphology, myocardial function and perfusion ascertained by all available methods.

    Annual surveillance coronary angiograpyhy to screen for graft coronary vasculopathy is routine practice after orthotopic heart transplantation. Traditionally, this is performed with direct coronary angiography using static single-plane or biplane angiography. Recently, technological advances have made it possible to perform dual-axis rotational coronary angiography (RA). This technique differs from standard static single-plane or biplane angiography in that a single detector is preprogrammed to swing through a complex 80° arc during a single injection. It has the advantage of providing a perspective of the vessels from a full arc of images rather than from one or two static images per contrast injection. The current study evaluated two coronary angiography techniques used consecutively at a single center to evaluate pediatric heart transplant recipients for graft coronary vasculopathy. A total of 23 patients underwent routine coronary angiography using both biplane static coronary angiography (BiP) and RA techniques at the Children's Hospital of Wisconsin from February 2009 to September 2010. Demographic and procedure data were collected from each procedure and analyzed for significance utilizing a Wilcoxon rank sum test. No significant demographic or procedural differences between the BiP and the RA procedures were noted. Specific measures of radiation dose including fluoroscopy time and dose area product were similar among the imaging techniques. The findings show that RA can be performed safely and reproducibly in pediatric heart transplant recipients. Compared with standard BiP, RA does not increase radiation exposure or contrast use and in our experience has provided superior angiographic imaging for the evaluation of graft coronary vasculopathy.

    Coronary heart disease is the leading cause of death worldwide, and its incidence is rapidly accelerating in developing nations. Patients often search for therapies that are alternatives to traditional treatments, such as heart medicines, coronary bypass surgery, or coronary stenting. Ayurveda is an ancient, East Indian, holistic approach to health care, and its use has never been formally evaluated for patients with coronary heart disease. The study intended to examine the feasibility and effectiveness of comprehensive ayurvedic therapy-incorporating diet, meditation, breathing exercises, yoga, and herbs-for patients with established coronary heart disease. The study was a prospective, single-group, pilot study. The study took place at the University of New Mexico Cardiology Clinic and at the Ayurvedic Institute in Albuquerque, NM, USA. The participants were adults with a history of a prior heart attack, coronary bypass surgery, or a coronary intervention (ie, a coronary angioplasty and/or stent). All enrolled patients were evaluated by a single ayurvedic physician with >40 y of experience, and each received therapy consisting of a calorically unrestricted ayurvedic diet; instruction in yoga, meditation, and breathing; and use of ayurvedic herbs. The primary endpoint was arterial pulse wave velocity, a marker of arterial function and vascular health. Secondary endpoints included the following measurements: (1) body mass index (BMI); (2) blood pressure (BP) and amount of reduction in BP medications; and (3) levels of total cholesterol, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, and triglycerides. All parameters were measured at baseline and after 90 d of therapy. Twenty-two patients were enrolled in the study, and 19 patients completed it. The research team observed significant improvements in arterial pulse wave velocity (P = .015), and favorable reductions in BMI (P ayurveda on arterial function and multiple risk

    For decades it has been postulated that the main environmental factor for coronary heart disease (CHD) was the intake of saturated fatty acids (SFA). Nevertheless, confirmation of the role of SFA in CHD through intervention trials has been disappointing. It was only when the diet was enriched in n-3 fatty acids that CHD was significantly prevented, especially cardiac death. In addition to n-3 fatty acids, many other foodstuffs or nutrients such as fibers, antioxidants, folic acid, calcium and even alcohol contribute to prevent CHD. Thus the relationship between diet and CHD morbidity and mortality appears to be much more complex than formerly suspected considering as key factors only SFA, linoleic acid, cholesterol and atherosclerosis. Some of the mechanisms are briefly described, but many additional nutrients (or non nutrients) may also play an important role in the pathogenesis of CHD. Finally, as a result of the most recent epidemiologic studies the ideal diet may comprise: 8% energy from SFA, 5% from polyunsaturated fatty acids with a ratio 5/1 of linoleic/alpha-linolenic acid+longer chains n-3, oleic acid as desired, large intake of cereals, vegetables, legumes and fruits, fish twice a week, cheese and yogurt as dairy products, rapeseed and olive oils as edible fat. Without side effects, such a diet can be highly palatable, easily enjoyed by many populations and may prevent effectively and rapidly (within a few weeks or months) CHD.

    The image quality and optimal reconstruction interval for coronary arteries in heart transplant recipients undergoing non-invasive dual-source computed tomography (DSCT) coronary angiography was evaluated. Twenty consecutive heart transplant recipients who underwent DSCT coronary angiography were included (19 male, one female; mean age 63.1±10.7 years). Data sets were reconstructed in 5% steps from 30% to 80% of the R-R interval. Two blinded independent observers assessed the image quality of each coronary segments using a five-point scale (from 0 = not evaluative to 4=excellent quality). A total of 289 coronary segments in 20 heart transplant recipients were evaluated. Mean heart rate during the scan was 89.1±10.4 bpm. At the best reconstruction interval, diagnostic image quality (score ≥2) was obtained in 93.4% of the coronary segments (270/289) with a mean image quality score of 3.04± 0.63. Systolic reconstruction intervals provided better image quality scores than diastolic reconstruction intervals (overall mean quality scores obtained with the systolic and diastolic reconstructions 3.03±1.06 and 2.73±1.11, respectively; P<0.001). Different systolic reconstruction intervals (35%, 40%, 45% of RR interval) did not yield to significant differences in image quality scores for the coronary segments (P=0.74). Reconstructions obtained at the systolic phase of the cardiac cycle allowed excellent diagnostic image quality coronary angiograms in heart transplant recipients undergoing DSCT coronary angiography.

    Objective To examine associations between loneliness and risk of incident coronary heart disease (CHD) over a 19-year follow-up period in a community sample of men and women. Loneliness, the perceived discrepancy between actual and desired social relationships, has been linked to several adverse health outcomes. However, no previous research has prospectively examined the association between loneliness and incident CHD in a community sample of men and women. Methods Hypotheses were examined using data from the First National Health and Nutrition Survey and its follow-up studies (n = 3003). Loneliness, assessed by one item from the Center for Epidemiologic Studies of Depression scale, and covariates were derived from baseline interviews. Incident CHD was derived from hospital records/death certificates over 19 years of follow-up. Hypotheses were evaluated, using Cox proportional hazards models. Results Among women, high loneliness was associated with increased risk of incident CHD (high: hazard ratio = 1.76, 95% Confidence Interval = 1.17â2.63; medium: hazard ratio = 0.98, 95% Confidence Interval = 0.64â1.49; reference: low), controlling for age, race, education, income, marital status, hypertension, diabetes, cholesterol, physical activity, smoking, alcohol use, systolic and diastolic blood pressures, and body mass index. Findings persisted additionally controlling for depressive symptoms. No significant associations were observed among men. Conclusions Loneliness was prospectively associated with increased risk of incident CHD, controlling for multiple confounding factors. Loneliness among women may merit clinical attention, not only due to its impact on quality of life but also its potential implications for cardiovascular health. PMID:19661189

    Full Text Available Abstract Introduction There is a strong clinical need to provide effective stress reduction programs for patients with an acute coronary syndrome. Such programs for men have been implemented and their cardiovascular health benefit documented. For women such programs are scarce. In this report, The feasibility of a cognitive method that was recently demonstrated to prolong lives of women is tested. A setting with gender segregated groups was applied. Method The principles of a behavioural health educational program originally designed to attenuate the stress of patients with coronary prone behaviours were used as a basis for the intervention method. For the groups of female patients this method was tailored according to female stressors and for the groups of men according to male stressors. The same core stress reduction program was used for women and men, but the contents of discussions and responses to the pre planned program varied. These were continuously monitored throughout the fifteen sessions. Implementation group: Thirty consecutive patients, eleven women and nineteen men, hospitalized for an acute coronary syndrome were included in this intervention. All expressed their need to learn how to cope with stress in daily life and were highly motivated. Five groups, three groups of men and two groups of women were formed. Psychological assessments were made immediately before and after completion of the program. Results No gender differences in the pre planned programs were found, but discussion styles varied between the women and men, Women were more open and more personal. Family issues were more frequent than job issues, although all women were employed outside their homes. Men talked about concrete and practical things, mostly about their jobs, and not directly about their feelings. Daily stresses of life decreased significantly for both men and women, but more so for women. Depressive thoughts were low at baseline, and there was no

    Full Text Available Kawasaki syndrome is an acute systemic vasculitis of unknown etiology, which mainly affects children within the first 5 years of fife. At the present time, Kawasaki syndrome is recognized to be a leading cause of acquired organic heart diseases in children, which may result in coronary heart disease, myocardial infarction, and sudden death in children and young people. Most complications are associated with the cardiovascular system, with coronary artery changes in particular. Transthoracic echocardiography, which, besides coronary artery assessment, makes it possible to evaluate right and left ventricular systolic and diastolic functions and to study the cardiac valves and changes in pericardial effusion, is a major technique in Kawasaki syndrome. The paper outlines an update on the epidemiology, etiology, pathogenetic mechanisms, and pathomorphology of Kawasaki syndrome and considers possible coronary and noncoronary changes, outcomes, and clinical manifestations.

    Thallium-201 myocardial imaging provides a non-invasive technique in the investigation of patients with suspected coronary heart disease. This study was designed to evaluate thallium-201 ( 201 Tl) scintigraphy in predicting the presence or absence of coronary heart disease in 50 patients presenting with chest pain. The results suggest that computer analysed 201 Tl exercise scintigraphy is a valuable technique for identifying patients with significant coronary artery disease. 201 Tl image data were highly sensitive for detecting the presence of coronary artery disease though accuracy in predicting the extent of disease was limited in patients with multiple vessel disease. The data provides further justification for the use of exercise 201 Tl scintigraphy especially in conjunction with exercise electrocardiography in the investigation of patients with chest pain.

    Full Text Available Left ventricular noncompaction (LVNC is a myocardial disorder probably due to the arrest of normal embryogenesis of the left ventricle. It could be isolated or associated with other extracardiac and cardiac abnormalities, including coronary artery anomalies. Despite the continuous improvement of imaging resolution quality, this cardiomyopathy still remains frequently misdiagnosed, especially if associated with other heart diseases. We report a case of LVNC association with both malposition of the great arteries and a very original coronary artery pattern.

    For patients with stable coronary artery disease (SCAD), either after hospitalization for acute cardiac events or in the chronic phase, comprehensive treatment programs should be devoted to: (i) reducing mortality and major adverse cardiovascular events, (ii) reducing the ischemic burden and related symptoms, and (iii) increasing exercise capacity and quality of life.Heart rate (HR) has demonstrated to have prognostic value and patients beyond the limit of 70 bpm display increased risk of all the above adverse outcomes, even after adjustment for parameters such as the extension of myocardial infarction and the presence of heart failure. It is well known that a sustained HR elevation may contribute to the pathogenesis of SCAD, being the likelihood of developing ischemia, plaque instability, trigger for arrhythmias, increased vascular oxidative stress, and endothelial dysfunction the mechanisms resulting in this effect. Moreover, high HR could promote chronotropic incompetence, leading to functional disability and reduced quality of life.Despite the strong relationship between HR and prognosis, there is heterogeneity among current guidelines in considering HR as a formal therapeutic target for secondary prevention in SCAD, as far as the cut-off limit. This expert opinion document considered major trials and observational registries in the modern treatment era with beta-blockers and ivabradine, suggesting that an adequate HR control could represent a target for (i), (ii), and (iii) therapeutic goals in SCAD patients with systolic dysfunction (with major evidence for reduced left ventricular ejection fraction SCAD patients with preserved left ventricular ejection fraction. The defined cut-off limit is 70 bpm. To date, there is room for improvement of HR control, since in contemporary SCAD patients HR values <70 bpm are present in less than half of cases, even in the vulnerable phase after an acute coronary syndrome.

    This paper presents data on the nascence and development of the interventional cardiology service in Kazakhstan. It provides details of the structure of the Kazakhstan interventional cardiology service, staff training, the number of coronary and structural heart interventions for the period of 2010-2015, as well as the peculiarities of the capitation payment method. The number of coronary interventions is increasing year by year, though the number of intracoronary imaging techniques and intracoronary flow/pressure techniques remains inadequate. Structural heart interventions are mostly performed at tertiary hospital level, with an ever increasing number of transcatheter aortic valve implantation (TAVI) procedures.

    A coronary heart disease index was developed from longitudinal ECG (LCG) tracings to serve as a cardiac health measure in studies of working and, essentially, asymptomatic populations, such as pilots and executives. For a given subject, the index consisted of a composite score based on the presence of LCG aberrations and weighted values previously assigned to them. The index was validated by correlating it with the known presence or absence of CHD as determined by a complete physical examination, including treadmill, resting ECG, and risk factor information. The validating sample consisted of 111 subjects drawn by a stratified-random procedure from 5000 available case histories. The CHD index was found to be significantly more valid as a sole indicator of CHD than the LCG without the use of the index. The index consistently produced higher validity coefficients in identifying CHD than did treadmill testing, resting ECG, or risk factor analysis.

    Elevated heart rate could negatively influence cardiovascular risk in the general population. It can induce and promote the atherosclerotic process by means of several mechanisms involving endothelial shear stress and biochemical activities. Furthermore, elevated heart rate can directly increase heart ischemic conditions because of its skill in unbalancing demand/supply of oxygen and decreasing the diastolic period. Thus, many pharmacological treatments have been proposed in order to reduce heart rate and ameliorate the cardiovascular risk profile of individuals, especially those suffering from coronary artery diseases (CAD) and chronic heart failure (CHF). Ivabradine is the first pure heart rate reductive drug approved and currently used in humans, created in order to selectively reduce sinus node function and to overcome the many side effects of similar pharmacological tools (ie, β-blockers or calcium channel antagonists). The aim of our review is to evaluate the role and the safety of this molecule on CAD and CHF therapeutic strategies. PMID:24940047

    To evaluate the association of performance in cognitive domains executive function and memory with incident coronary heart disease and stroke in older participants without dementia. We included 3,926 participants (mean age 75 years, 44% male) at risk for cardiovascular diseases from the Prospective Study of Pravastatin in the Elderly at Risk (PROSPER) with Mini-Mental State Examination score ≥24 points. Scores on the Stroop Color-Word Test (selective attention) and the Letter Digit Substitution Test (processing speed) were converted to Z scores and averaged into a composite executive function score. Likewise, scores of the Picture Learning Test (immediate and delayed memory) were transformed into a composite memory score. Associations of executive function and memory were longitudinally assessed with risk of coronary heart disease and stroke using multivariable Cox regression models. During 3.2 years of follow-up, incidence rates of coronary heart disease and stroke were 30.5 and 12.4 per 1,000 person-years, respectively. In multivariable models, participants in the lowest third of executive function, as compared to participants in the highest third, had 1.85-fold (95% confidence interval [CI] 1.39-2.45) higher risk of coronary heart disease and 1.51-fold (95% CI 0.99-2.30) higher risk of stroke. Participants in the lowest third of memory had no increased risk of coronary heart disease (hazard ratio 0.99, 95% CI 0.74-1.32) or stroke (hazard ratio 0.87, 95% CI 0.57-1.32). Lower executive function, but not memory, is associated with higher risk of coronary heart disease and stroke. Lower executive function, as an independent risk indicator, might better reflect brain vascular pathologies. © 2015 American Academy of Neurology.

    The FINRISK risk calculator predicts 10-year risk for coronary heart disease, stroke incidence, and their combination. The model is based on 10-year cohort follow-up from 3 different cohorts in 1982, 1987, and 1992 from a random population sample in 3 areas in Finland. Coronary heart disease, stroke, and their combination are predicted by smoking, systolic blood pressure, total cholesterol, high-density lipoprotein cholesterol, diabetes, and family history. The Internet-based calculator is commonly used in Finland in health services to assess the need for hypertension and hypercholesterolemia treatment and is used also in patients' counseling.

    Purpose: To evaluate a new coronary MR angiography technique covering the whole coronary artery tree in one data set acquisition. Materials and methods: Six healthy volunteers and 15 patients with known CAD were examined with a navigator gated and corrected (NAV) free-breathing 3D steady-state free precession sequence covering the whole heart (WH-MRA) (TR=5.4, TE-2.7, SENSE factor=2, 160 slices, 0.75 mm reconstructed slice thickness, in-plane resolution =0.99 x 0.99 mm 2 , scan time 14 min [50% NAV efficiency]) and a vessel targeted 3D SSFP MRA sequence (t-MRA) (TR=5.6 ms, TE-2.8 ms, 20 slices of 1.5 mm reconstructed slice thickness, in-plane resolution =0.99 x 0.99 mm 2 , scan time=7 min [50% NAV efficiency]). Subjective image quality (4-point scale) and objective image quality parameters including vessel sharpness, vessel diameter and CNR were calculated for WH-MRA and t-MRA. In patients, the accuracy for detection of stenosis larger than 50% was compared to the accuracy of X-ray coronary angiography (XA), which was considered the standard. Results: WH-MRA demonstrated good vessel visibility in healthy subjects (100%) whereas vessel visibility in patients was limited (78% in an 8 segment evaluation). Vessel sharpness was inferior to that of t-MRA in patients (37 vs. 42%) but equal in healthy subjects (42%). Vessel diameter did not differ significantly between WH-MRA and t-MRA. CNR was significantly reduced for WH-MRA (CNR 7.4 vs. 11.5). The diagnostic accuracy for the detection of CAD was comparable for both MRA approaches (85.5 vs. 86.2%). Conclusion: WH-MRA allows good coronary artery visualization in healthy subjects and patients and provides a simplified scanning procedure and advantages in 3D post-processing. Regarding image parameters and the detection of CAD, the results are comparable to those acquired with t-MRA. The major disadvantage remains the high number of diagnostically insufficient images.

    We examined whether slow heart rate recovery (HRR) after exercise testing as an estimate of impaired autonomic function is related to coronary artery calcification (CAC), an emerging marker of coronary atherosclerosis. We evaluated 2088 men who participated in a health-screening program that included measures of CAC and peak or symptom-limited cardiopulmonary exercise testing. HRR was calculated as the difference between peak heart rate (HR) during exercise testing and the HR at 2 min of recovery after peak exercise. We measured CAC using multidetector computed tomography to calculate the Agatston coronary artery calcium score. Advanced CAC was defined as a mean CAC >75th percentile for each age group. HRR was negatively correlated with CAC (r = -.14, p 52 bpm). Each 1 bpm decrease in HRR was associated with 1% increase in advanced CAC after adjusting for potential confounders. An attenuated HRR after exercise testing is associated with advanced CAC, independent of coronary risk factors and other related hemodynamic response. KEY MESSAGES Slow heart rate recovery (HRR) after maximal exercise testing, indicating decreased autonomic function, is associated with an increased risk of cardiovascular event and mortality. Slow HRR has been linked with the occurrence of malignant ventricular arrhythmias, but it remains unclear whether slow HRR is associated with an increased risk of coronary artery calcification (CAC), an emerging marker of coronary atherosclerosis. An attenuated HRR after exercise testing was associated with advanced CAC, independent of coronary risk factors and other potential hemodynamic confounder, supporting the hypothesis that slow HRR is related to the burden of atherosclerotic coronary artery disease.

    Whole mount visualization of the embryonic coronary plexus from which the capillary and arterial networks will form is rendered problematic using standard microscopy techniques, due to the scattering of imaging light by the thick heart tissue, as these vessels are localized deep within the walls of the developing heart. As optical clearing of tissues using organic solvents such as BABB (1 part benzyl alcohol to 2 parts benzyl benzoate) has been shown to greatly improve the optical penetration depth that can be achieved, we combined clearance of whole, PECAM1-immunostained hearts, with laser-scanning confocal microscopy, in order to obtain high-resolution images of vessels throughout the entire heart. BABB clearance of embryonic hearts takes place rapidly and also acts to preserve the fluorescent signal for several weeks; in addition, samples can be imaged multiple times without loss of signal. This straightforward method is also applicable to imaging other types of blood vessels in whole embryos.

    Full Text Available Objective: To analyze the correlation between serum Hcy content and coronary atherosclerosis severity in patients with H-type hypertension and coronary heart disease. Methods: 48 patients with H-type hypertension and coronary heart disease were selected as observation group, and 57 patients with normal hypertension and coronary heart disease were selected as control group. Echocardiography was used to determine coronary lesion parameters, enzymelinked immunosorbent assay (ELISA was used to determine serum levels of homocysteine (Hcy and coronary heart disease-related indexes, and the correlation between Hcy levels and coronary heart disease was further analyzed. Results: Serum Hcy level of observation group was higher than that of control group (P<0.05, absolute GLPSS value and E/A value under echocardiography were less than those of control group while E-DT and E/e value were higher than those of control group (P<0.05; serum adiponectin (APN level was lower than that of control group while P-selectin, asymmetric dimethylarginine (ADMA, oxidized high-density lipoprotein (OX-HDL, MMP-2, MMP-9, lipoprotein-associated phospholipase A2 (Lp-PLA2 and Resistin levels were higher than those of control group (P<0.05; Hcy was negatively correlated with absolute GLPSS value, E/A value and APN level, and was positively correlated with E-DT value, E/e value as well as P-selectin, ADMA, OX-HDL, MMP-2, MMP-9, Lp- PLA2 and Resistin levels (P<0.05. Conclusions: There is direct correlation between serum Hcy levels and the severity of coronary heart disease in patients with H-type hypertension and coronary heart disease, it can be a reliable way to early screen for coronary heart disease and evaluate the illness, and it is also a new target of coronary heart disease intervention.

    Background The burden of coronary heart disease (CHD) worldwide is one of great concern to patients and healthcare agencies alike. Exercise-based cardiac rehabilitation aims to restore patients with heart disease to health. Objectives To determine the effectiveness of exercise-based cardiac rehabilitation (exercise training alone or in combination with psychosocial or educational interventions) on mortality, morbidity and health-related quality of life of patients with CHD. Search methods RCTs have been identified by searching CENTRAL, HTA, and DARE (using The Cochrane Library Issue 4, 2009), as well as MEDLINE (1950 to December 2009), EMBASE (1980 to December 2009), CINAHL (1982 to December 2009), and Science Citation Index Expanded (1900 to December 2009). Selection criteria Men and women of all ages who have had myocardial infarction (MI), coronary artery bypass graft (CABG) or percutaneous transluminal coronary angioplasty (PTCA), or who have angina pectoris or coronary artery disease defined by angiography. Data collection and analysis Studies were selected and data extracted independently by two reviewers. Authors were contacted where possible to obtain missing information. Main results This systematic review has allowed analysis of 47 studies randomising 10,794 patients to exercise-based cardiac rehabilitation or usual care. In medium to longer term (i.e. 12 or more months follow-up) exercise-based cardiac rehabilitation reduced overall and cardiovascular mortality [RR 0.87 (95% CI 0.75, 0.99) and 0.74 (95% CI 0.63, 0.87), respectively], and hospital admissions [RR 0.69 (95% CI 0.51, 0.93)] in the shorter term (< 12 months follow-up) with no evidence of heterogeneity of effect across trials. Cardiac rehabilitation did not reduce the risk of total MI, CABG or PTCA. Given both the heterogeneity in outcome measures and methods of reporting findings, a meta-analysis was not undertaken for health-related quality of life. In seven out of 10 trials reporting health

    THE CONTEXT: Patients with coronary heart disease are generally males aged more than 55 and in whom the question of sexual activity must be evoked, not only with regard to the risks involved with the sexual act itself but also regarding the management of an eventual erectile dysfunction. POSITIVE DATA: A negative and maximal for the age stress test is of predictive value and can eliminate the hypothesis of recurrent coronary ischaemia during sexual intercourse. Drug-induced effects on the libido and erectile function are known but only led to suspension of treatment in one out 438 patients treated for one year. In the case of documented erectile dysfunction, the combination of sildenafil nitrate derivatives or NO suppliers is formally contra-indicated because of the risk of hypotension. Post-marketing registers and specific studies in patients with coronary heart disease demonstrate the good haemodynamic and coronary tolerance to sildenafil in this category of patient, so long as the contra-indications are respected. The Princeton Consensus Panel has proposed a therapeutic strategy adapted to each patient and according to their level of risk and its treatment.

    Differences in drug prescribing for coronary heart disease have previously been identified by age, sex and ethnic group. Set in the UK, our study utilises routinely collected data from 98 general practices serving a socially diverse population in inner East London, to examine differences in prescribing rates among patients aged 35 years and over with coronary heart disease. 10,933 patients aged 35 years or more, with recorded coronary heart disease, from 98 practices in two Primary Care Trusts (PCT) in East London during 2009/2010 were included for this cross-sectional study. Multivariable logistic regression was used to assess the odds of prescribing for recommended coronary heart disease drugs by age, sex, ethnicity, social deprivation, co-morbidity and recorded reasons for not prescribing. Women are prescribed fewer recommended coronary heart disease drugs than men; Black African/Caribbean patients are prescribed fewer lipid modifying drugs and other cardiovascular drugs than White patients. Patients over age 84 are prescribed fewer lipid modifying drugs and beta blockers than patients aged 45-54. South Asian patients had the highest levels of prescribing and higher prevalence of coronary heart disease and diabetes co-morbidity. No difference in prescribing rates by social deprivation was found. Overall levels of prescribing are high but small differences between sex and ethnic groups remain and prescribing may be inequitable for women, for Black/African Caribbeans and at older ages. These differences were not explained by recorded intolerance, contraindications or declining treatment.

    Full Text Available Abstract Objective: The incidence of depression and anxiety is higher in patients with acute coronary syndrome. The aim of this study is to determine whether experiencing acute coronary syndrome prior to open heart surgery affects patients in terms of depression, hopelessness, anxiety, fear of death and quality of life. Methods: The study included 63 patients who underwent coronary bypass surgery between January 2015 and January 2016. The patients were divided into two groups: those diagnosed after acute coronary syndrome (Group 1 and those diagnosed without acute coronary syndrome (Group 2. Beck depression scale, Beck hopelessness scale, Templer death anxiety scale and death depression scale, State-Trait anxiety inventory and WHOQOL-Bref quality of life scale were applied. Results: There was no significant difference between the two groups in terms of the total score obtained from Beck depression scale, Beck hopelessness scale - future-related emotions, loss of motivation, future-related expectations subgroups, death anxiety scale, the death depression scale, State-Trait Anxiety Inventory - social and environmental subgroups. The mental quality of life sub-scores of group 2 were significantly higher. The patients in both groups were found to be depressed and hopeless about the future. Anxiety levels were found to be significantly higher in all of the patients in both groups. Conclusion: Acute coronary syndrome before coronary artery bypass surgery impairs more the quality of life in mental terms. But unexpectedly there are no differences in terms of depression, hopelessness, anxiety and fear of death.

    The anomalous origin of the left coronary artery (LCA) from the pulmonary artery (ALCAPA) and congenital left main coronary artery atresia (CLMCA-A) are two kinds of very rare coronary heart diseases which affect heart function profoundly. This study aimed to retrospectively illustrate the clinical features and therapy experience of ALCAPA and CLMCA-A patients. From April 1984 to July 2012, in Beijing Anzhen Hospital, 23 patients were diagnosed with ALCAPA and 4 patients with CLMCA-A. We summarized the clinical data of the 27 cases and retrospectively analyzed the clinical manifestation, diagnosis, and treatments of these two kinds of congenital coronary abnormalities. The 23 patients (13 males and 10 females, aged ranging from 2.5 months to 65 years) identified with ALCAPA were classified into infantile type (age of onset younger than 12 months, 16 cases) and adult type (age of onset older than 12 months, 7 cases). Four patients were diagnosed with CLMCA-A (three males and one female, aged ranging from 3 months to 2 years). The main clinical manifestations of infantile-type ALCAPA and CLMCA-A include repeated respiratory tract infection, heart failure, dyspnea, feeding intolerance, diaphoresis, and failure to thrive. And these two congenital coronary abnormalities might be misdiagnosed as endocardial fibroelastosis, dilated cardiomyopathy, and acute myocardial infarction. As for the adult-type ALCAPA, cardiac murmurs and discomfort of the precordial area are the most common presentations and might be misdiagnosed as coronary heart disease, myocarditis, or patent ductus arteriosus. In ECG examination: Infantile-type ALCAPA and CLMCA-A showed abnormal Q waves with T wave inversion in leads I, avL, and V4-V6, especially in lead avL. However, ECG of adult-type ALCAPA lacked distinct features. In chest radiography: pulmonary congestion and cardiomegaly were the most common findings in infantile-type ALCAPA and CLMCA-A, while pulmonary artery segment dilation was more

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.

    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.

    Full Text Available Abstract Background The determination of coronary flow reserve (CFR is an essential concept at the moment of decision-making in ischemic heart disease. There are several direct and indirect tests to evaluate this parameter. In this sense, dobutamine stress echocardiography is one of the pharmacological method most commonly used worldwide. It has been previously demonstrated that CFR can be determined by this technique. Despite our wide experience with dobutamine stress echocardiography, we ignored the necessary heart rate to consider sufficient the test for the analysis of CFR. For this reason, our main goal was to determine the velocity of coronary flow in each stage of dobutamine stress echocardiography and the heart rate value necessary to double the baseline values of coronary flow velocity in the territory of the left anterior descending (LAD coronary artery. Methods A total of 33 consecutive patients were analyzed. The patients included had low risk for coronary artery disease. All the participants underwent dobutamine stress echocardiography and coronary artery flow velocity was evaluated in the distal segment of LAD coronary artery using transthoracic color-Doppler echocardiography. Results The feasibility of determining CFR in the territory of the LAD during dobutamine stress echocardiography was high: 31/33 patients (94%. Mean CFR was 2.67 at de end of dobutamine test. There was an excellent concordance between delta HR (difference between baseline HR and maximum HR and the increase in the CFR (correlation coefficient 0.84. In this sense, we found that when HR increased by 50 beats, CFR was ≥ 2 (CI 93-99.2%. In addition, 96.4% of patients reached a CFR ≥ 2 (IC 91.1 - 99% at 75% of their predicted maximum heart rate. Conclusions We found that the feasibility of dobutamine stress echocardiography to determine CFR in the territory of the LAD coronary artery was high. In this study, it was necessary to achieve a difference of 50 bpm

    Several epidemiological studies have shown that the prevalence of ischemic heart disease is higher in occupational drivers than in people with other occupations. Although occupation categories can be surrogate measures for coronary risk factors, the relationships between taxi driving and severity of coronary heart disease (CHD) has not been investigated. Even more important, the contribution of risk factors to the severity of CHD in taxi drivers remains unclear. Our study tested the hypothesis that taxi driving could be associated with the severity of CHD. We also examined the relation between this occupation and risk factors and social lifestyle. We analyzed the coronary angiograms of 57 consecutive male taxi driver patients and compared them with those of 215 age-adjusted male non-taxi-driver patients. The number of diseased vessels and risk factors were compared between two groups. The prevalence of myocardial infarction and multi-vessel disease was higher in the taxi-driver patients than in the non-taxi-driver patients. The taxi-driver patients had higher prevalence of body mass index (BMI), diabetes, and smoking, higher levels of low-density lipoprotein cholesterol (LDL-C), and lower levels of apolipoprotein AI (ApoAI). Multiple logistic regression analysis showed that multi-vessel disease was associated with BMI and diabetes mellitus in taxi-driver patients. The taxi-driver patients were characterized by more extensive coronary atherosclerosis associated with higher prevalence of diabetes mellitus and obesity. These characteristics may be explained by in part their working environment.

  16. Effects of bileaflet mechanical heart valve orientation on coronary flow

    2015-11-01

    The aortic sinus is approximately tri-radially symmetric, but bileaflet mechanical heart valves (BMHVs), which are commonly used to replace diseased aortic valves, are bilaterally symmetric. This mismatch in symmetry suggests that the orientation in which a BMHV is implanted within the aortic sinus affects the flow characteristics downstream of it. This study examines the effect of BMHV orientation on the flow in the coronary arteries, which originate in the aortic sinus and supply the heart tissue with blood. Planar particle image velocimetry measurements were made past a BMHV mounted at the inlet of an anatomical aorta model under physiological flow conditions. The complex interactions between the valve jets, the sinus vortex and the flow in the right coronary artery were elucidated for three valve orientations. The coronary flow rate was directly affected by the size, orientation, and time evolution of the vortex in the sinus, all of which were sensitive to the valve's orientation. The total flow through the artery was highest when the valve was oriented with its axis of symmetry intersecting the artery's opening. The findings of this research may assist surgeons in choosing the best orientation for BMHV implantation. The bileaflet valve was donated by St. Jude Medical. Financial support was provided by the Natural Sciences and Engineering Research Council of Canada.

It can induce and promote the atherosclerotic process by means of several mechanisms involving endothelial shear stress and biochemical activities. Furthermore, elevated heart rate can directly increase heart ischemic conditions because of its skill in unbalancing demand/supply of oxygen and decreasing the diastolic period. Thus, many pharmacological treatments have been proposed in order to reduce heart rate and ameliorate the cardiovascular risk profile of individuals, especially those suffering from coronary artery diseases (CAD and chronic heart failure (CHF. Ivabradine is the first pure heart rate reductive drug approved and currently used in humans, created in order to selectively reduce sinus node function and to overcome the many side effects of similar pharmacological tools (ie, β-blockers or calcium channel antagonists. The aim of our review is to evaluate the role and the safety of this molecule on CAD and CHF therapeutic strategies.

    Full Text Available Abstract Background Several investigations are currently available to establish the diagnosis of coronary heart disease (CHD. Of these, cardiovascular magnetic resonance (CMR offers the greatest information from a single test, allowing the assessment of myocardial function, perfusion, viability and coronary artery anatomy. However, data from large scale studies that prospectively evaluate the diagnostic accuracy of multi-parametric CMR for the detection of CHD in unselected populations are lacking, and there are few data on the performance of CMR compared with current diagnostic tests, its prognostic value and cost-effectiveness. Methods/design This is a prospective diagnostic accuracy cohort study of 750 patients referred to a cardiologist with suspected CHD. Exercise tolerance testing (ETT will be preformed if patients are physically able. Recruited patients will then undergo CMR and single photon emission tomography (SPECT followed in all patients by invasive X-ray coronary angiography. The order of the CMR and SPECT tests will be randomised. The CMR study will comprise rest and adenosine stress perfusion, cine imaging, late gadolinium enhancement and whole-heart MR coronary angiography. SPECT will use a gated stress/rest protocol. The primary objective of the study is to determine the diagnostic accuracy of CMR in detecting significant coronary stenosis, as defined by X-ray coronary angiography. Secondary objectives include an assessment of the prognostic value of CMR imaging, a comparison of its diagnostic accuracy against SPECT and ETT, and an assessment of cost-effectiveness. Discussion The CE-MARC study is a prospective, diagnostic accuracy cohort study of 750 patients assessing the performance of a multi-parametric CMR study in detecting CHD using invasive X-ray coronary angiography as the reference standard and comparing it with ETT and SPECT.

    Full Text Available Abstract Background The prevention and treatment of coronary heart disease (CHD is complex. A variety of models have therefore been developed to try and explain past trends and predict future possibilities. The aim of this systematic review was to evaluate the strengths and limitations of existing CHD policy models. Methods A search strategy was developed, piloted and run in MEDLINE and EMBASE electronic databases, supplemented by manually searching reference lists of relevant articles and reviews. Two reviewers independently checked the papers for inclusion and appraisal. All CHD modelling studies were included which addressed a defined population and reported on one or more key outcomes (deaths prevented, life years gained, mortality, incidence, prevalence, disability or cost of treatment. Results In total, 75 articles describing 42 models were included; 12 (29% of the 42 models were micro-simulation, 8 (19% cell-based, and 8 (19% life table analyses, while 14 (33% used other modelling methods. Outcomes most commonly reported were cost-effectiveness (36%, numbers of deaths prevented (33%, life-years gained (23% or CHD incidence (23%. Among the 42 models, 29 (69% included one or more risk factors for primary prevention, while 8 (19% just considered CHD treatments. Only 5 (12% were comprehensive, considering both risk factors and treatments. The six best-developed models are summarised in this paper, all are considered in detail in the appendices. Conclusion Existing CHD policy models vary widely in their depth, breadth, quality, utility and versatility. Few models have been calibrated against observed data, replicated in different settings or adequately validated. Before being accepted as a policy aid, any CHD model should provide an explicit statement of its aims, assumptions, outputs, strengths and limitations.

    Cerebro-vascular disease is a commonest long term complication of type-2 diabetes mellitus. The study was done to determine concentration of serum adiponectin and lipid profile in type-2 diabetic men with coronary heart disease (CHD) in the region of Khyber Pakhtunkhwa (KPK), and to find possible relationship between them. Methods: This was a cross-sectional study comprising of randomly selected thirty six healthy adult males and thirty six type-2 diabetic males with coronary heart disease. Their fasting blood samples were analysed for serum adiponectin, fasting blood glucose, glycosylated haemoglobin and lipid profile which included total cholesterol (T-C), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C). The relationship of adiponectin with other variables in type-2 diabetic men with coronary heart disease was determined with Pearson correlations coefficient (r). Results: Type-2 diabetic males with coronary heart disease when compared to healthy males showed significantly low levels of serum adiponectin (p=<0.001) and HDL-C (p=<0.001) and significantly high level of FBG (p=<0.001), HbA1c (p=<0.001), TC (p=<0.05), TG (p=<0.05) and LDL-C (p=<0.05). Serum adiponectin level showed a significant negative correlation with FBG (r = -0.332; p= 0.04), HbA1c (r = -0.818; p=<0.01) and TG (r = -0.640; p=<0.01) in type-2 diabetic men with coronary heart disease. Adiponectin showed a significant positive association with HDL-C in controls (r = 0.948; p=<0.01) and patients of type-2 diabetes with CHD (r = 0.650; p=<0.01). Conclusion: Serum adiponectin concentration is markedly decreased in patients of type-2 diabetes with coronary heart disease. Hypoadiponectinemia is related with deranged lipid profile, i.e., high TG and low HDL-C levels in type-2 diabetic men with CHD. Moreover, adiponectin is associated positively with HDL-C and negatively with HbA1c and TG levels in the studied population. (author)

Next, the effect of heart rate and calcification on the accuracy of coronary artery stenosis detection was analyzed by using an invasive coronary angiography as a reference standard. Coronary segments of less than 1.5 mm in diameter in an American Heart Association (AHA) 15-segment model were independently assessed. The mean heart rate during the scan was 71.8 bpm, whereas the mean Agatston score was 226.5. Of the 1,588 segments examined, 1,533 (97%) were assessable. A total of 17 patients had calcium scores above 400 Agatston U, whereas 50 had heart rates ≥ 70 bpm. Overall the sensitivity, specificity, positive predictive values (PPV) and negative predictive values (NPV) for significant stenoses were: 95%, 91%, 65%, and 99% (by segment), respectively and 97%, 90%, 81%, and 91% (by artery), respectively (n = 475). Heart rate showed no significant impact on lesion detection; however, vessel calcification did show a significant impact on accuracy of assessment for coronary segments. The specificity, PPV and accuracy were 96%, 80%, and 96% (by segment), respectively for an Agatston score less than 100% and 99%, 96% and 98% (by artery). For an Agatston score of greater to or equal to 400 the specificity, PPV and accuracy were reduced to 79%, 55%, and 83% (by segment), respectively and to 79%, 69%, and 85% (by artery), respectively. The DSCT provides a high rate of accuracy for the detection of significant coronary artery disease, even in patients with high heart rates and evidence of coronary calcification. However, patients with severe coronary calcification (> 400 U) remain a challenge to diagnose

    The aim of study was to examine echocardiographic indices of right heart chambers in patients with coronary artery disease in different age groups. On 678 patients aged 38-85 years, who underwent echocardiography, are including with the use of spectral tissue Doppler. Obtained 2 age groups: 1st - patients up to 60 years (n=282) and group 2nd - patients 60 years and older (n=396). In the analysis the obtained results in patients with coronary heart disease in older age groups showed an increase in right ventricular wall thickness, systolic and average pressure in the pulmonary artery. These changes were accompanied by deterioration in left ventricular diastolic function, while the systolic function of the left and right ventricle were independent of age. Thus, the results can be recommended for assessment of right ventricular dysfunction in patients of older age groups.

    Strong epidemiologic and experimental data suggest that increasing dietary fiber may help to lower low-density lipoprotein cholesterol (LDL-C) and decrease the risk of coronary heart disease. Recent studies have highlighted the role of dietary fiber, particularly water-soluble varieties, in decreasing the risk of cardiovascular disease. Several types of soluble fiber, including psyllium, beta-glucan, pectin, and guar gum, have been shown to decrease LDL-C in well-controlled intervention studies, whereas the soluble fiber content of legumes and vegetables has also been shown to decrease LDL-C. Current investigations continue to explore this area in depth and examine potential synergies between dietary fiber and other phytochemicals that may lower cholesterol. These studies, along with recent analyses of ongoing prospective cohort studies, have provided new insights into the probable protective role of dietary fiber in the development of coronary heart disease and other cardiovascular diseases.

    To investigate the effect on coronary arterial attenuations of contrast material flow rate adjusted to a patient's heart rate during dual source CT coronary angiography (DSCT-CCTA). A total of 296 consecutive patients (mean age: 58.7 years) undergoing DSCT-CCTA without previous coronary stent placement, bypass surgery, congenital or valvular heart disease were included. The image acquisition protocol was standardized (120 kV, 380 mAs) and retrospective electrocardiograph (ECG) gating was used. Patients were randomly assigned to one of three groups [flow rate: G1: dosage/16, G2: dosage/(scan time +8), G3: fixed flow rate]. The groups were compared with respect to the attenuations of the ascending aorta (AA) above coronary ostia, the left main coronary artery (LM), the proximal right coronary artery (RCA), the left anterior descending artery (LAD), the left circumflex artery (LCX), and the contrast to noise ratio of the LM (LM(CNR)) and the proximal RCA (RCA(CNR)). Correlations between heart rate and attenuation of the coronary arteries were evaluated in three groups with linear regression. There was no significant difference in the three groups among the mean attenuations of AA (P = 0.141), LM (P = 0.068), RCA (P = 0.284), LM(CNR) (P = 0.598) and RCA(CNR) (P = 0.546). The attenuations of the LAD and the LCX in group 1 were slightly higher than those in group 2 and 3 (P material flow rate adjusted to heart rate can diminish the influence of heart rate on attenuations of the coronary arteries in DSCT-CCTA.

    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.

    Heart rate (HR) is a risk factor in patients with chronic systolic heart failure (HF) that, when reduced, provides outcome benefits. It is also a target for angina pectoris prevention and a risk marker in chronic coronary artery disease without HF. HR can be reduced by drugs; however, among those used clinically, only ivabradine reduces HR directly in the sinoatrial nodal cells without other known effects on the cardiovascular system. This review provides current information regarding the safety and efficacy of HR reduction with ivabradine in clinical studies involving >36,000 patients with chronic stable coronary artery disease and >6,500 patients with systolic HF. The largest trials, Morbidity-Mortality Evaluation of the I f Inhibitor Ivabradine in Patients With Coronary Disease and Left Ventricular Dysfunction and Study Assessing the Morbidity-Mortality Benefits of the I f Inhibitor Ivabradine in Patients With Coronary Artery Disease, showed no effect on outcomes. The Systolic Heart Failure Treatment With the I f Inhibitor Ivabradine Trial, a randomized controlled trial in >6,500 patients with HF, revealed marked and significant HR-mediated reduction in cardiovascular mortality or HF hospitalizations while improving quality of life and left ventricular mechanical function after treatment with ivabradine. The adverse effects of ivabradine predominantly included bradycardia and atrial fibrillation (both uncommon) and ocular flashing scotomata (phosphenes) but otherwise were similar to placebo. In conclusion, ivabradine improves outcomes in patients with systolic HF; rates of overall adverse events are similar to placebo. Copyright © 2016 Elsevier Inc. All rights reserved.

    Nuclear techniques studies of the heart represent one of the fastest growing areas of research. Several years ago, nuclear medicine cardiac studies were limited for the evaluation and diagnosis of myocardial infarction. Development in radiopharmaceutical-chemistry and instrumentation have made possible advances in nuclear medicine for restenosis cardiovascular therapy after percutaneous transluminal coronary angioplasty.The radionuclide as radiation source can be delivered to the target basically by two techniques, those are catheter-based systems and radioactive stents. For this purpose,it can be use the γ and β emitter radionuclides, in which the β emitter radionuclides is an ideal radionuclide for endovascular therapy. Restenosis after percutaneous transluminal coronary angioplasty can be prevented by using the radioactive stent. This review discusses several techniques which could be used for restenosis cardiovascular therapy. Furthermore, several types of radiopharmaceutical and kinds of radionuclides as well as doses of the compounds for this purpose are also reviewed. (author)

    Coronary heart disease (CHD) is the single most common cause of death globally. However, with falling CHD mortality rates, an increasing number of people live with CHD and may need support to manage their symptoms and prognosis. Exercise-based cardiac rehabilitation (CR) aims to improve the health and outcomes of people with CHD. This is an update of a Cochrane systematic review previously published in 2011. To assess the effectiveness and cost-effectiveness of exercise-based CR (exercise training alone or in combination with psychosocial or educational interventions) compared with usual care on mortality, morbidity and HRQL in patients with CHD.To explore the potential study level predictors of the effectiveness of exercise-based CR in patients with CHD. We updated searches from the previous Cochrane review, by searching Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, Issue 6, 2014) from December 2009 to July 2014. We also searched MEDLINE (Ovid), EMBASE (Ovid), CINAHL (EBSCO) and Science Citation Index Expanded (December 2009 to July 2014). We included randomised controlled trials (RCTs) of exercise-based interventions with at least six months' follow-up, compared with a no exercise control. The study population comprised men and women of all ages who have had a myocardial infarction (MI), coronary artery bypass graft (CABG) or percutaneous coronary intervention (PCI), or who have angina pectoris, or coronary artery disease. We included RCTs that reported at least one of the following outcomes: mortality, MI, revascularisations, hospitalisations, health-related quality of life (HRQL), or costs. Two review authors independently screened all identified references for inclusion based on the above inclusion and exclusion criteria. One author extracted data from the included trials and assessed their risk of bias; a second review author checked data. We stratified meta-analysis by the duration of follow up of trials, i.e. short-term: 6

    1994-11-01

    The aim of our review is to summarize relevant data on the perioperative use of anti-ischaemic drugs in patients at risk for or with proven coronary heart disease. The accessible medical literature according to current electronic information sources was explored. One in every eight general anaesthetics is administered to a patient at risk for or with proven coronary heart disease. Of these patients, it is estimated that 20%-40% have perioperative myocardial ischaemia (PMI), the majority being non-symptomatic. This figure correlates with the occurrence of postoperative cardiac complications and myocardial infarction. The anaesthetist therefore has an important role to play in reducing the rate of perioperative cardiac sequelae. This can be achieved with good control of haemodynamic stability and the timely and appropriate use of antiischaemic drugs. Nitrocompounds (nitrates, molsidomine) serve as the gold standard in current angina pectoris treatment. Acting as coronary and systemic vasodilators, they effect an immediate reduction in preload and have been shown to be the drugs of first choice for intraoperative myocardial ischaemia. Beta-blockers reduce the rate of PMI to a greater extent than nitrates. They are also effective in myocardial ischaemia not accompanied by an increased heart rate. Single pre-operative administration of beta-blockers has also been shown to be beneficial in reducing the incidence of perioperative tachycardia, hypertension, and PMI. Consequently, such one-time medication can be considered for previously untreated high-risk patients presenting for surgery. The continuation of oral calcium channel blockers to the morning of surgery also reduces the rate of PMI and myocardial infarction in coronary-bypass patients, and combination with beta-blockers enhances this effect. Intra-operative diltiazem infusions are similarly advantageous in this patient group. In addition to nitrates, calcium antagonists are the drug of choice for coronary

  18. The role of Homocysteine as a predictor for coronary heart disease

    Directory of Open Access Journals (Sweden)

    Schramm, Susanne

    2007-11-01

    Full Text Available Background and objective: There is an ongoing debate on the role of the cytotoxic aminoacid homocysteine as a causal risk factor for the development of coronary heart disease. Results from multiple case control-studies demonstrate, that there is a strong association between high plasma levels of homoysteine and prevalent coronary heart disease, independent of other classic risk factors. Furthermore, results from interventional studies point out that elevated plasma levels of homocysteine may effectively be lowered by the intake of folic acid and B vitamins. In order to use this information for the construction of a new preventive strategy against coronary heart disease, more information is needed: first, whether homocysteine actually is a causal risk factor with relevant predictive properties and, second, whether by lowering elevated homocysteine plasma concentrations cardiac morbidity can be reduced. Currently in Germany the determination of homocysteine plasma levels is reimbursed for by statutory health insurance in patients with manifest coronary heart disease and in patients at high risk for coronary heart disease but not for screening purposes in asymptomatic low risk populations.Against this background the following assessment sets out to answer four questions: 1. Is an elevated homocysteine plasma concentration a strong, consistent and independent (of other classic risk factors predictor for coronary heart disease? 2. Does a therapeutic lowering of elevated homoysteine plasma levels reduce the risk of developing coronary events? 3. What is the cost-effectiveness relationship of homocysteine testing for preventive purposes? 4. Are there morally, socially or legally relevant aspects that should be considered when implementing a preventive strategy as outlined above? Methods: In order to answer the first question, a systematic overview of prospective studies and metaanalyses of prospective studies is undertaken. Studies are included that

    Purpose: To evaluate the risk of coronary heart disease (CHD) and cerebrovascular disease after radiotherapy (RT) for peptic ulcer disease. Methods and materials: Peptic ulcer disease patients treated with RT (n = 1859) or by other means (n = 1860) at the University of Chicago Medical Center between 1936 and 1965, were followed through 1997. The observed numbers of cause-specific deaths were compared with the expected numbers from the general population rates. During RT, 5% of the heart was in the treatment field and the remainder of the heart mostly received scattered radiation. A volume-weighted cardiac dose was computed to describe the average tissue dose to the entire organ. We used Cox proportional hazards regression analysis to analyze the CHD and cerebrovascular disease risk associated with RT, adjusting for confounding factors. Results: Greater than expected CHD mortality was observed among the irradiated patients. The irradiated patients received volume-weighted cardiac doses ranging from 1.6 to 3.9 Gy and the portion of the heart directly in the field received doses of 7.6-18.4 Gy. The CHD risk increased with the cardiac dose (p trend = 0.01). The cerebrovascular disease risk was not associated with the surrogate carotid dose. Conclusion: The excess CHD risk in patients undergoing RT for peptic ulcer disease decades previously indicates the need for long-term follow-up for cardiovascular disease after chest RT

    Full Text Available Objective: To analyze the ultrasound assessment of mitral annular displacement in patients with coronary heart disease and its correlation with left heart function and serum indexes. Methods: A total of 89 patients with coronary heart disease were divided into angina pectoris group 42 cases and myocardial infarction group 47 cases according to the illness, and 58 cases of healthy subjects were included in control group. Values of mitral annular displacement (MAD parameters, left heart function indexes and serum illness-related indexes of three groups were detected, and the correlation between values of MAD parameters and values of cardiac function indexes and serum illness-related indexes were further analyzed. Results: MAD parameters TMAD1, TMAD2 and TMADmid values, heart function LVEF values and serum CysC level of myocardial infarction group and angina pectoris group were lower than those of control group, and cardiac function LVEDD, LVESD and A/E values as well as serum H-FABP, ICTP, Hcy and vWF levels were higher than those of control group (P<0.05; MAD parameters TMAD1, TMAD2 and TMADmid values of patients with coronary heart disease were negatively correlated with LVEDD, LVESD and A/E values as well as H-FABP, ICTP, Hcy and vWF levels, and were positively correlated with LVEF value and CysC level (P<0.05. Conclusions: Ultrasound assessment of mitral annular displacement in patients with coronary heart disease can early diagnose coronary heart disease and judge the disease severity, and it plays a positive role in optimizing disease prognosis.

    Abstract Background: We aimed to quantitatively assess the potential relationship between kidney stones and coronary heart disease or stroke. Methods: 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). Results: 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; I2 = 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; I2 = 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; I2 = 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). Conclusion: Kidney stones are associated with increased risk of coronary heart disease and stroke, and the effect may differ by sex.

    An increase in mean platelet volume has been reported to be associated with arterial thrombosis and myocardial infarction. A larger mean platelet volume has been regarded as an independent risk factor for recurrent myocardial infarction. We therefore investigated whether it is also increased in patients with coronary heart disease examined a few days before cardiac surgery. Four hundred and twenty-six patients with coronary heart disease who were waiting for cardiac surgery and 125 healthy individuals were included in the study. Mean platelet volume and other platelet parameters were obtained from a routine blood count procedure using a flow cytometric haematology analyser. Mean platelet volume did not differ significantly between patients and controls; however, as expected from the literature, patients had significantly elevated levels of fibrinogen, cholesterol, triglyceride, apolipoprotein B and apolipoprotein(a). Furthermore, we observed no significant difference in mean platelet volume between patients without myocardial infarction and those who had survived at least one myocardial infarction. Our findings suggest that, using a routine laboratory procedure, mean platelet volume cannot be used as a predictive marker for coronary heart disease or myocardial infarction.

    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

    Patients with prosthetic heart valves may require assessment for coronary artery disease. We assessed whether valve artefacts hamper coronary artery assessment by multidetector CT. ECG-gated or -triggered CT angiograms were selected from our PACS archive based on the presence of prosthetic heart valves. The best systolic and diastolic axial reconstructions were selected for coronary assessment. Each present coronary segment was scored for the presence of valve-related artefacts prohibiting coronary artery assessment. Scoring was performed in consensus by two observers. Eighty-two CT angiograms were performed on a 64-slice (n = 27) or 256-slice (n = 55) multidetector CT. Eighty-nine valves and five annuloplasty rings were present. Forty-three out of 1160 (3.7%) present coronary artery segments were non-diagnostic due to valve artefacts (14/82 patients). Valve artefacts were located in right coronary artery (15/43; 35%), left anterior descending artery (2/43; 5%), circumflex artery (14/43; 32%) and marginal obtuse (12/43; 28%) segments. All cobalt-chrome containing valves caused artefacts prohibiting coronary assessment. Biological and titanium-containing valves did not cause artefacts except for three specific valve types. Most commonly implanted prosthetic heart valves do not hamper coronary assessment on multidetector CT. Cobalt-chrome containing prosthetic heart valves preclude complete coronary artery assessment because of severe valve artefacts. circle Most commonly implanted prosthetic heart valves do not hamper coronary artery assessment circle Prosthetic heart valve composition determines the occurrence of prosthetic heart valve-related artefacts circle Bjoerk-Shiley and Sorin tilting disc valves preclude diagnostic coronary artery segment assessment.

Cobalt-chrome containing prosthetic heart valves preclude complete coronary artery assessment because of severe valve artefacts. • Most commonly implanted prosthetic heart valves do not hamper coronary artery assessment • Prosthetic heart valve composition determines the occurrence of prosthetic heart valve-related artefacts • Björk-Shiley and Sorin tilting disc valves preclude diagnostic coronary artery segment assessment.

    In patients with acute coronary syndrome (ACS) who underwent coronary arteries revascularization, violations of hemodynamics, metabolism and heart rate variability often develop in the postoperative period, therefore, the goal of the study was to establish the features of disturbances and the effectiveness of correction of left ventricular systolic and diastolic dysfunction and heart rate variability in stages of cardiorehabilitation in patients with acute coronary syndrome who underwent coronary arteries revascularization. The experimental group included 40 patients with ACS in the postoperative period who underwent balloon angioplasty and stenting of the coronary arteries (25 patients with ST-segment elevation ACS and 15 patients without ST-segment elevation ACS). The age of examined patients was 37 to 74 years, an average of 52.6±6.7 years. The control group consisted of 20 patients, comparable in age and clinico-laboratory manifestations of ACS, who underwent drug treatment with direct anticoagulants, double antiplatelet therapy, β-blockers, ACE inhibitors and statins. Clinical efficacy of cardiorespiratory process in patients of both groups was assessed by the dynamics of general clinical symptoms and parameters of natriuretic propeptide, systolic and diastolic function of the left ventricle and heart rate variability. In the initial state, clinical and laboratory-instrumental signs of myocardial ischemia disappear in patients with ACS undergoing surgical revascularization of the coronary arteries, but clinical and subclinical manifestations of heart failure were diagnosed. The use of the accelerated program of cardiac rehabilitation already during the first month of studies leads to a decreasement of the signs of systolic and diastolic dysfunction, the level of NT-proBNP and improve in the variability of the heart rhythm wich significantly improves the life quality of patients with ACS. To monitor the effectiveness and safety of cardiac rehabilitation in

    The benefit of CT coronary angiography (CTCA) in patients presenting with stable chest pain has not been systematically studied. We aimed to assess the effect of CTCA on the diagnosis, management, and outcome of patients referred to the cardiology clinic with suspected angina due to coronary heart disease. In this prospective open-label, parallel-group, multicentre trial, we recruited patients aged 18-75 years referred for the assessment of suspected angina due to coronary heart disease from 12 cardiology chest pain clinics across Scotland. We randomly assigned (1:1) participants to standard care plus CTCA or standard care alone. Randomisation was done with a web-based service to ensure allocation concealment. The primary endpoint was certainty of the diagnosis of angina secondary to coronary heart disease at 6 weeks. All analyses were intention to treat, and patients were analysed in the group they were allocated to, irrespective of compliance with scanning. This study is registered with ClinicalTrials.gov, number NCT01149590. Between Nov 18, 2010, and Sept 24, 2014, we randomly assigned 4146 (42%) of 9849 patients who had been referred for assessment of suspected angina due to coronary heart disease. 47% of participants had a baseline clinic diagnosis of coronary heart disease and 36% had angina due to coronary heart disease. At 6 weeks, CTCA reclassified the diagnosis of coronary heart disease in 558 (27%) patients and the diagnosis of angina due to coronary heart disease in 481 (23%) patients (standard care 22 [1%] and 23 [1%]; pcoronary heart disease increased (1·09, 1·02-1·17; p=0·0172), the certainty increased (1·79, 1·62-1·96; pcoronary heart disease. This changed planned investigations (15% vs 1%; pcoronary heart disease, CTCA clarifies the diagnosis, enables targeting of interventions, and might reduce the future risk of myocardial infarction.

    The prevalence of coronary artery disease (CAD) in valvular patients is similar to that of the general population, with the usual association with traditional risk factors. Nevertheless, the search for obstructive CAD is more aggressive in the preoperative period of patients with valvular heart disease, resulting in the indication of invasive coronary angiography (ICA) to almost all adult patients, because it is believed that coronary artery bypass surgery should be associated with valve replacement. To evaluate the prevalence of obstructive CAD and factors associated with it in adult candidates for primary heart valve surgery between 2001 and 2014 at the National Institute of Cardiology (INC) and, thus, derive and validate a predictive obstructive CAD score. Cross-sectional study evaluating 2898 patients with indication for heart surgery of any etiology. Of those, 712 patients, who had valvular heart disease and underwent ICA in the 12 months prior to surgery, were included. The P value arterial hypertension, diabetes mellitus, dyslipidemia, smoking, and male gender. The model showed excellent correlation and calibration (R² = 0.98), as well as excellent accuracy (ROC of 0.848; 95%CI: 0.817-0.879) and validation (ROC of 0.877; 95%CI: 0.830 - 0.923) in different valve populations. Obstructive CAD can be estimated from clinical data of adult candidates for valve repair surgery, using a simple, accurate and validated score, easy to apply in clinical practice, which may contribute to changes in the preoperative strategy of acquired heart valve surgery in patients with a lower probability of obstructive disease.

    Full Text Available To evaluate the coding, recording and incidence of coronary heart disease (CHD in primary care electronic medical records.Data were drawn from the UK General Practice Research Database. Analyses evaluated the occurrence of 271 READ medical diagnostic codes, including categories for 'Angina', 'Myocardial Infarction', 'Coronary Artery Bypass Grafting' (CABG, 'percutaneous transluminal coronary angioplasty' (PCTA and 'Other Coronary Heart Disease'. Time-to-event analyses were implemented to evaluate occurrences of different groups of codes after the index date.Among 300,020 participants aged greater than 30 years there were 75,197 unique occurrences of coronary heart disease codes in 24,244 participants, with 12,495 codes for incident events and 62,702 for prevalent events. Among incident event codes, 3,607 (28.87% were for angina, 3,262 (26.11% were for MI, 514 (4.11% for PCTA, 161 (1.29% for CABG and 4,951 (39.62% were for 'Other CHD'. Among prevalent codes, 20,254 (32.30% were for angina, 3,644 (5.81% for MI, 34,542 (55.09% for 'Other CHD' and 4,262 (6.80% for CABG or PCTA. Among 3,685 participants initially diagnosed exclusively with 'Other CHD' codes, 17.1% were recorded with angina within 5 years, 5.6% with myocardial infarction, 6.3% with CABG and 8.6% with PCTA. From 2000 to 2010, the overall incidence of CHD declined, as did the incidence of angina, but the incidence of MI did not change. The frequency of CABG declined, while PCTA increased.In primary care electronic records, a substantial proportion of coronary heart disease events are recorded with codes that do not distinguish between different clinical presentations of CHD. The results draw attention to the need to improve coding practice in primary care. The results also draw attention to the importance of code selection in research studies and the need for sensitivity analyses using different sets of codes.

    To evaluate the correlation between the coronary sinus flow and the infusion volume in the coronaries and assess the performance of coronary sinus flow in predicting coronary artery occlusion in an isolated pig heart. The coronary sinus flow was measured in 16 isolated pig hearts by pulsed Doppler ultrasound. The correlation between the coronary sinus flow and the infusion volume in different coronary artery was analyzed, and the performance of coronary sinus flow in predicting different coronary artery occlusion was deducted. There were no statistically significant differences between the coronary sinus flow and the infusion volume in different coronary artery (p>0.05). The correlations between the coronary sinus flow and the infusion volume in left anterior descending coronary artery (LAD), left circumflex coronary artery (LCX), LAD and LCX, and LAD, LCX and right coronary artery (RCA) were all higher than 0.85 (p85% sensitivity and specificity. Excepting RCA mild occlusion (80% sensitivity and specificity. Conclusions The coronary sinus flow measured by pulsed Doppler ultrasound can effectively and exactly reflect the infusion volume in coronaries, which is a powerful indicator of coronary blood supply.

    Full Text Available Objective: The aim of our study was to evaluate the association between cytochrome P450 2C19 (CYP2C19 681G>A polymorphisms and the age of development of coronary heart disease. Additionally, the study might find some biological indicators at the gene level that could help to predict and evaluate the risk of coronary heart disease in time. Methods: This study included 352 individuals with coronary heart disease. Polymerase chain reaction–restriction fragment length polymorphism (PCR-RFLP was used to identify CYP2C19 681G>A. The objects were divided into wild type (GG or homozygous CYP2C19*1 wild-type and mutant type (GA/AA or the mutant CYP2C19*2 allele on the basis of genotype. The association between CYP2C19 gene polymorphism and the age of onset of coronary heart disease was assessed by multivariate linear regression analysis. Results: There was a significant association in the age of onset between the two groups (t=3.398, P=0.001, which was 58.51+12.72 years in the wild type and 53.95+11.63 years in the mutant group. The frequency of CYP2C19 681A (CYP2C19*2 allele was 3.32, 0.268, 0.227 in different age groups, which was significantly different (χ2=10.745, P=0.005 in different groups, as well as in the genotype. The result, assessed by multiple linear regression, showed that genotype, smoking, obesity, and hyperlipidemia affect the age of onset of coronary heart disease (β was -0.167, 0.156, 0.155, and 0.112, PA gene polymorphism may be one of the risk factors in susceptibility to early onset of coronary heart disease, but not an independent factor because other factors may play a synergistic role.

    Full Text Available 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.

    To assess the optimal timing for coronary magnetic resonance (MR) angiography in children with congenital heart disease by using dual cardiac phase whole-heart MR imaging. The local institutional review board approved this study, and informed consent was obtained from parents or guardians. Thirty children (13 girls; overall mean age, 5.01 years) were examined with a 1.5-T MR system. A free-breathing three-dimensional steady-state free precession dual cardiac phase sequence was used to obtain MR angiographic data during end-systolic and middiastolic rest periods. Vessel length, diameter, and sharpness, as well as image quality of the coronary artery segments, were analyzed and compared by using Bland-Altman plots, linear regression analysis, the t test, and Wilcoxon signed rank tests. Optimal coronary artery imaging timing was patient dependent and different for each coronary artery segment (36 segments favored end systole, 28 favored middiastole). In 15 patients (50%), different segments favored different cardiac phases within the same patient. Image quality and vessel sharpness degraded with higher heart rates, with a similar correlation for end systole (right coronary artery [RCA], 0.39; left main [LM] coronary artery, 0.46; left anterior descending [LAD] artery, 0.51; and left circumflex [LCX] artery, 0.50) and middiastole (RCA, 0.34; LM, 0.45; LAD, 0.48; and LCx, 0.55). Mean image quality difference or mean vessel sharpness difference showed no indication to prefer a specific cardiac phase. The optimal cardiac rest period for coronary MR angiography in children with congenital heart disease is specific for each coronary artery segment. Dual cardiac phase whole-heart coronary MR angiography enables optimal coronary artery visualization by retrospectively choosing the optimal imaging rest period.

    Implementing the evidence base for the management of chronic disease is as challenging as discovering which interventions are effective. The HEARTS collaboration (Heart disease Evidence-based Audit and Research in Tayside Scotland) is achieving that goal for the secondary prevention of coronary heart disease (CHD by linking national databases to manually validated hospital and family practice electronic patient records. Specific data from the system is fed back to practices in a facilitated educational process and through the NHS intranet. This paper describes some of the key features of this strategic decision support system. All residents of the Tayside region of Scotland (n=484,013 mid year estimate 2002) are covered by the system. 9,828 patients who have suffered a myocardial infarction(MI) or who have undergone angioplasty or bypass surgery are registered on the system. Improvements in clinical status and prescribing of effective therapies are 5-10% greater than elsewhere in Scotland.

    2006-01-01

    An inverse association between height and risk of coronary heart disease (CHD) is well demonstrated, but it is not known whether this association is because of genetic factors, socioeconomic background, or other environmental factors. Four population-based twin cohorts with register-based follow.......99 million person-years of follow-up. Cox and conditional logistic regression models were used. Per 1-standard deviation decrease in height, height was inversely associated with CHD mortality in men (hazard ratio = 1.08, 95% confidence interval (CI): 1.04, 1.12) and in women (hazard ratio = 1.06, 95% CI: 1...... = 1.14, 95% CI: 1.01, 1.28). The inverse association between height and CHD mortality found within monozygotic discordant twin pairs suggests that this association is because of environmental factors that directly affect height and CHD risk....

    Sofhauser, Cynthia D

    2003-09-01

    Although it is known that hostility precedes coronary heart disease (CHD), little is known about factors that influence the development and progression of hostile characteristics. The relations among hostility, self-esteem, self-concept, and psychosocial residual were conceptualized within the modeling and role-modeling theoretical framework and examined in a sample of 85 persons with CHD. There were significant associations between all variables. Regression analyses revealed that self-esteem, mistrust residual, isolation residual, and self-concept contributed significantly, accounting for 31% of the variation in hostility scores. These findings provide support for the belief that the development of hostility in persons with CHD is related to beliefs and attitudes about the self and others. Persons with self-esteem need deficits, and a subsequent build up of negative psychosocial residual, have poor self-concepts. This poor self-concept is hostile in nature and reflects a mistrust of others and a deep sense of isolation.

    The Middle East and North Africa has witnessed a dramatic transformation over the last 30 years caused by rapid urbanization and modernization and significant changes to diet and lifestyle. This review attempts to highlight recent data in regards to ischemic heart disease and its risk factors from the region. Ischemic heart disease is now the leading cause of death in the region. Age at presentation with myocardial infarction and acute coronary syndrome appears to be significantly younger than global averages. Increased rates of all major risk factors including diabetes, hypertension, hyperlipidemia, smoking, obesity, and sedentary lifestyle have been noted. Specifically, significant changes to dietary habits and growing epidemic of use of alternative tobacco products are noted. This review article highlights the growing epidemic of ischemic heart disease in the region led by dramatic increases in incidence of its risk factors. This epidemic will require a multipronged approach to address the varied issues and mitigate the growing prevalence of the disease.

    The association between coronary heart disease (CHD) and dietary fiber intake is not consistent, especially for the subtypes of dietary fiber. The aim of our study was to conduct a meta-analysis of existing cohort published studies assessing the association between dietary fiber intake and risk of CHD, and quantitatively estimating their dose-response relationships. We searched PubMed and EMBASE before May 2013. Random-effect model was used to calculate the pool relative risk (RRs) for the incidence and mortality of CHD. Dose-response, subgroup analyses based on fiber subtypes, heterogeneity and publication bias were also carried out. Eighteen studies involving 672,408 individuals were finally included in the present study. The pooled-adjusted RRs of coronary heart disease for the highest versus lowest category of fiber intake were 0.93 (95% confidence interval (CI), 0.91-0.96, P fiber subtypes (cereal, fruit, and vegetable fiber), indicated that RRs were 0.92 (95% CI, 0.85-0.99, P = 0.032), 0.92 (95% CI, 0.86-0.98, P = 0.01), 0.95 (95% CI, 0.89-1.01, P = 0.098) respectively for all coronary event and 0.81 (95% CI, 0.72-0.92, P = 0.001), 0.68 (95% CI, 0.43-1.07, P = 0.094), 0.91 (95% CI, 0.74-1.12, P = 0.383) for mortality. In addition, a significant dose-response relationship was observed between fiber intake and the incidence and mortality of CHD (P dietary fiber is inversely associated with risk of coronary heart disease, especially for fiber from cereals and fruits. Besides, soluble and insoluble fibers have the similar effect. A significant dose-response relationship is also observed between fiber intake and CHD risk.

    Interventional cardiology procedures are constantly increasing in numbers and in quality, especially in developing countries such as Egypt. The numbers and types of procedure now available have driven development in the field and in its accompanying services. The aim of this short report is to present a review of the development of interventional cardiology in Egypt during the period 2010-2015 and the demographic, economic and educational factors that have affected this process. We collected and analysed data provided by different centres and from the distributors of intervention tools for the years 2010 to 2015. Analysis of these data showed a steady growth of primary PCI, amounting to a threefold increase over the six-year period. There are increasing numbers of PCI-capable centres, especially in Cairo. Almost 55,000 PCIs are performed yearly in Egypt utilising around 100,000 stents; the percentage of drug-eluting stents (DES) used has increased to 65-70% (90% in private and insured patients). Structural intervention is growing fast for congenital heart disease, and balloon mitral valvuloplasty has become the default strategy. The numbers of TAVI and EVAR are also increasing, although cost remains the greatest challenge. These changes can be attributed to the increasing numbers of ischaemic heart disease patients over the last 25 years, involving improved education and awareness, patients presenting at a younger age, and improved practice in intervention. In Egypt, there has been a steady growth in PCI and intervention tools which has been faster in coronary and congenital heart disease than in structural heart disease during the period from 2010 to 2015.

    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.

    The presence and extent of coronary artery calcium (CAC) are associated with increased risk for cardiovascular events. We determined whether information on the distribution of CAC and coronary dominance as detected by cardiac computed tomography were incremental to traditional Agatston score (AS) in predicting incident major coronary heart disease (CHD). We assessed total AS and the presence of CAC per coronary artery, per segment, and coronary dominance by computed tomography in participants from the offspring and third-generation cohorts of the Framingham Heart Study. The primary outcome was major CHD (myocardial infarction or CHD death). We performed multivariable Cox proportional hazards analysis and calculated relative integrated discrimination improvement. In 1268 subjects (mean age, 56.2±10.3 years, 63.2% men) with AS >0 and no history of major CHD, a total of 42 major CHD events occurred during median follow-up of 7.4 years. The number of coronary arteries with CAC (hazard ratio, 1.68 per artery; 95% confidence interval, 1.10-2.57; P =0.02) and the presence of CAC in the proximal dominant coronary artery (hazard ratio, 2.59; 95% confidence interval, 1.15-5.83; P =0.02) were associated with major CHD events after multivariable adjustment for Framingham risk score and categories of AS. In addition, measures of CAC distribution improved discriminatory capacity for major CHD events (relative integrated discrimination improvement, 0.14). Distribution of coronary atherosclerosis, especially CAC in the proximal dominant coronary artery and an increased number of coronary arteries with CAC, predict major CHD events independently of the traditional AS in community-dwelling men and women. © 2017 American Heart Association, Inc.

    2013-09-01

    Full Text Available Cardiovascular diseases are caused because of abnormalities in the heart and blood vessels. Recent trends reveal that the incidence of coronary heart disease (CHD has gradually decreased in many developed countries, but the situation remains quite challenging in developing nations that account for more than 60% of the global burden. Multiple socio-demographic, personal, physician related and healthcare delivery system related factors have been identified which act in variable combinations to either influence the incidence of CHD or affect the short/long-term outcome of the disease. Of all CHD cases who succumb within 28 days of onset of symptoms, almost 67% fail to reach even a hospital. This clearly signifies the importance of primary prevention and early recognition of the warning signs in averting cause-specific mortality. The main priority is to develop cost-effective equitable health care innovations in CHD prevention and to monitor the trend of CHD so that evidence-based interventions can be formulated. To conclude, inculcating health-promoting behaviors in school children and the general population by means of community-based health screening and education interventions could avert many more deaths attributed to CHDs.

    Although metabolomic profiling offers promise for the prediction of coronary heart disease (CHD), and metabolic risk factors are more strongly associated with CHD in women than men, limited data are available for women. We applied a liquid chromatography-tandem mass spectrometry metabolomics platform to measure 371 metabolites in a discovery set of postmenopausal women (472 incident CHD cases, 472 controls) with validation in an independent set of postmenopausal women (312 incident CHD cases, 315 controls). Eight metabolites, primarily oxidized lipids, were significantly dysregulated in cases after the adjustment for matching and CHD risk factors in both the discovery and validation data sets. One oxidized phospholipid, C34:2 hydroxy-phosphatidylcholine, remained associated with CHD after further adjustment for other validated metabolites. Subjects with C34:2 hydroxy-phosphatidylcholine levels in the highest quartile had a 4.7-fold increase in CHD odds in comparison with the lowest quartile; C34:2 hydroxy-phosphatidylcholine also significantly improved the area under the curve ( P <0.01) for CHD. The C34:2 hydroxy-phosphatidylcholine findings were replicated in a third replication data set of 980 men and women (230 cardiovascular events) with a stronger association observed in women. These data replicate known metabolite predictors, identify novel markers, and support the relationship between lipid oxidation and subsequent CHD. © 2018 American Heart Association, Inc.

    To study the relationship between homocysteine(Hcy), lipoprotein(a) [LP(a)], high sensitivity C-reactive protein(hs-CRP) and coronary atherosclerotic heart disease, coronary arteriographic finding-diagnosed 144 patients with coronary atherosclerosis were measured for Hcy LP(a) and hs-CRP levels in blood. The results showed that Hcy. LP(a) and hs-CRP levels of patients with coronary atherosclerosis were higher than those in controls, and were significantly associated with the number of attacked coronary artery branches. (P<0.01). As independent risk factors of atherosclerosis, Hcy, LP(a) and hs-CRP may play important roles in diagnosis and prognosis of coronary heart disease. (authors)

    Heart rate variability is a physiological feature indicating the influence of the autonomic nervous system on the heart rate. Association of the reduced heart rate variability due to myocardial infarction and the increased postinfarction mortality was first described more than thirty years ago. Many studies have unequivocally demonstrated that coronary artery bypass grafting surgery generally leads to significant reduction in heart rate variability, which is even more pronounced than after myocardial infarction. Pathophysiologically, however, the mechanisms of heart rate variability reduction associated with acute myocardial infarction and coronary artery bypass grafting are different. Generally, heart rate variability gradually recovers to the preoperative values within six months of the procedure. Unlike the reduced heart rate variability in patients having sustained myocardial infarction, a finding of reduced heart rate variability after coronary artery bypass surgery is not considered relevant in predicting mortality. Current knowledge about changes in heart rate variability in coronary patients and clinical relevance of such a finding in patients undergoing coronary artery bypass grafting are presented.

    Although the prevalence of coronary heart disease (CHD) in the United States has increased during the past 25 years, cardiovascular mortality has decreased due to advances in CHD therapy and prevention. We sought to determine the proportion of patients with CHD who die from cardiovascular versus noncardiovascular causes and the causes and predictors of death, in a cohort of patients with CHD. The Heart and Soul Study enrolled 1,024 participants with stable CHD from 2000 to 2002 and followed them for 10 years. Causes of mortality were assigned based on detailed review of medical records, death certificates, and coroner reports by blinded adjudicators. During 7,680 person-years of follow-up, 401 participants died. Of these deaths, 42.4% were cardiovascular and 54.4% were noncardiovascular. Myocardial infarction, stroke, and sudden death accounted for 72% of cardiovascular deaths. Cancer, pneumonia, and sepsis accounted for 67% of noncardiovascular deaths. Independent predictors of cardiac mortality were older age, inducible ischemia on stress echocardiography, higher heart rate at rest, smoking, lower hemoglobin, and higher N-terminal pro-brain natriuretic peptide (all p values <0.05); independent predictors of noncardiac mortality included older age, inducible ischemia, higher heart rate, lower exercise capacity, and nonuse of statins (all p values <0.05). In conclusion, mortality in this cohort was more frequently due to noncardiovascular causes, and predictors of noncardiovascular mortality included factors traditionally associated with cardiovascular mortality.

    The isolated beating pig heart model is an accessible platform to investigate the coronary circulation in its truly morphological and physiological state, whereas its use is beneficial from a time, cost, and ethical perspective. However, whether the coronary autoregulation is still intact is not known. Here, we study the autoregulation of coronary blood flow in the working isolated pig heart in response to brief occlusions of the coronary artery, to step-wise changes in left ventricular loading conditions and contractile states, and to pharmacologic vasodilating stimuli. Six slaughterhouse pig hearts (473 ± 40 g) were isolated, prepared, and connected to an external circulatory system. Through coronary reperfusion and controlled cardiac loading, physiological cardiac performance was achieved. After release of a coronary occlusion, coronary blood flow rose rapidly to an equal (maximum) level as the flow during control beats, independent of the duration of occlusion. Moreover, a linear relation was found between coronary blood flow and coronary driving pressure for a wide variation of preload, afterload, and contractility. In addition, intracoronary administration of papaverine did not yield a transient increase in blood flow indicating the presence of maximum coronary hyperemia. Together, this indicates that the coronary circulation in the isolated beating pig heart is in a permanent state of maximum hyperemia. This makes the model excellently suitable for testing and validating cardiovascular devices (i.e., heart valves, stent grafts, and ventricular assist devices) under well-controlled circumstances, whereas it decreases the necessity of sacrificing large mammalians for performing classical animal experiments. © 2013, Copyright the Authors.

  18. Role of depression in secondary prevention of Chinese coronary heart disease patients receiving percutaneous coronary intervention.

    Directory of Open Access Journals (Sweden)

    Can Feng

    Full Text Available Coronary heart disease (CHD patients who have undergone percutaneous coronary intervention (PCI have higher rates of depression than the general population. However, few researchers have assessed the impact of depression on the secondary prevention of CHD in China.The main purpose of this investigation was to explore the relationship between depression and secondary prevention of CHD in Chinese patients after PCI.This descriptive, cross-sectional one-site study recruited both elective and emergency PCI patients one year after discharge. Data from 1934 patients were collected in the clinic using questionnaires and medical history records between August 2013 and September 2015. Depression was evaluated by the 9-item Patient Health Questionnaire. Secondary prevention of CHD was compared between depression and non-depression groups.We found that depression affected secondary prevention of CHD in the following aspects: lipid levels, blood glucose levels, smoking status, physical activity, BMI, and rates of medication use.Depressive patients with CHD are at increased risk of not achieving the lifestyle and risk factor control goals recommended in the 2006 AHA guidelines. Screening should focus on patients after PCI because treating depression can improve outcomes by improving secondary prevention of CHD.

    Slow heart rate recovery (HRR) after exercise is considered to represent impaired parasympathetic tone and to be a predictor of all-cause and cardiovascular mortality, but the independent value of abnormal HRR in predicting the presence and severity of coronary artery disease (CAD) is unknown. The aim of this study was to evaluate these relationships in our patients. This prospective cross-sectional study included 208 patients (67.3% men), aged 34 to 74 (mean 53) years. Patients who had an ischemic response during symptom-limited exercise testing underwent selective coronary angiography. The value for HRR was defined as the decrease in heart rate from peak exercise to one minute after the exercise ceased. Eighteen beats per minute was defined as the lowest normal value for HRR. Significant CAD was detected in 140 (67.3%) patients. There were 66 (31.7%) patients with an abnormal HRR. In multivariable logistic regression analysis adjusted for established CAD risk factors, abnormal HRR was independently correlated with the extent of major epicardial coronary involvement (p = 0.04). The sensitivity, specificity, positive and negative predictive values, and accuracy of abnormal HRR for predicting extensive CAD were 48%, 83.3%, 72.7%, and 63.4%, respectively. There was also a significant correlation between HRR one minute after exercise and smoking (p = 0.004), chronotropic variables (p = 0.001), and the calculated risk score for the exercise test (p = 0.03). There was no significant correlation between HRR and other risk factors including age and gender, left ventricular systolic function, and history of myocardial infarction. There is a significant correlation between abnormal post-exercise HRR at one minute and the extent of major epicardial coronary involvement.

    To observe the effects of different loading doses of atorvastatin calcium on the outcomes of percutaneous coronary intervention (PCI) in elderly patients with coronary heart disease (CHD). A total of 120 CHD patients aged over 80 years were randomly assigned into 3 equal groups to receive intensive pretreatment with statin at the doses of 20, 40, or 60 mg prior to PCI performed within 48 to 72 h after admission. The changes of postoperative cardiac biochemical markers including creatine kinase isoenzyme (CKMB), troponin I (cTNI) and high-sensitivity c-reactive protein (hs-CRP) were observed and the incidence of major adverse cardiac events (MACE, including cardiac death, myocardial infarction, and target vessel revascularization) were recorded within 30 days after PCI. Thirty-four patients in 20 mg statin group, 40 in 40 mg statin group, and 38 in 60 mg statin group completed this study. In all the 3 groups, hs-CRP level significantly increased at 12 and 24 h after PCI compared with the preoperative levels (P0.05). Intensive pretreatment with 60 mg/day atorvastatin calcium can significantly reduce myocardial infarction related to PCI with good safety in elderly patients with CHD.

    To study the correlation of blood stasis syndrome or its accompanied syndromes with Gensini score in patients with coronary heart disease (CHD) in stable condition. The syndrome types of traditional Chinese medicine (TCM) and blood stasis score in 131 CHD patients confirmed by coronary angiography were recorded. Gensini score was calculated according to the coronary pathological characteristics showed by angiography. The correlations of blood stasis syndrome and its accompanied syndromes with coronary lesion and Gensini score were analyzed. Among the TCM syndrome types, blood stasis, turbid phlegm and qi deficiency were the most common syndromes, revealed in 85 patients (64.9%), 83 patients (63.4%) and 85 patients (64.9%), respectively. The coronary lesion length and Gensini score in the patients with blood stasis syndrome were much higher than those in the patients with non-blood stasis syndrome (Psyndrome were higher than those in the patients with non-blood stasis syndrome (Psyndrome score was more than 9 points, the coronary lesion length was higher than that in the patients whose blood stasis syndrome score was less than 9 points (Psyndrome score showed no correlation with Gensini score (Pearson correlation coefficient was 0.104, P=0.241). Blood stasis syndrome is the most common TCM syndrome in CHD patients in stable condition. The blood stasis syndrome score is proportional to coronary lesion length, and reflects the severity of coronary lesion.

    Cardiac rehabilitation (CR) is a complex multifaceted intervention consisting of three core modalities: education, exercise training and psychological support. Whilst exercise and psychological interventions for patients with coronary heart disease (CHD) have been the subject of Cochrane systematic reviews, the specific impact of the educational component of CR has not previously been investigated. 1. Assess effects of patient education on mortality, morbidity, health-related quality of life (HRQofL) and healthcare costs in patients with CHD.2. Explore study level predictors of the effects of patient education (e.g. individual versus group intervention, timing with respect to index cardiac event). The following databases were searched: The Cochrane Library, (CENTRAL, CDSR, DARE, HTA, NHSEED), MEDLINE (OVID), EMBASE (OVID), PsycINFO (EBSCOhost) and CINAHL (EBSCOhost). Previous systematic reviews and reference lists of included studies were also searched. No language restrictions were applied. 1. Randomised controlled trials (RCTs) where the primary interventional intent was education.2. Studies with a minimum of six-months follow-up and published in 1990 or later.3. Adults with diagnosis of CHD. Two review authors selected studies and extracted data.

    We studied the age and gender difference between acute coronary heart disease and ischaemic stroke risk and examined the extent to which such a difference may be explained by known risk factors. Data from Finnish and Swedish population-based cohorts including 9278 individuals were collaboratively analysed. Hazards ratios (95% confidence intervals) for coronary heart disease and stroke incidence were estimated using the Cox-proportional hazards model. The incidence of coronary heart disease and stroke was higher in all age groups in men than in women, and the gender difference was more marked for coronary heart disease than for ischaemic stroke. There was a 10-year lag in the development of coronary heart disease and stroke in women compared with men. The multivariable adjusted hazard ratios for the incidence of coronary heart disease in men and women were 3.87 (2.49-6.02) and 1.71 (1.07-2.74) at age 50-59 years, and 7.22 (4.59-11.36) and 3.49 (2.18-5.57) at age 60-69 years compared with women aged 40-49 years. For ischaemic stroke, they were 2.64 (1.45-4.82) and 2.17 (1.18-3.97) at age 50-59 years, and 5.19 (2.81-9.58) and 4.89 (2.67-8.97) at age 60-69 years, respectively. Acute coronary heart disease and ischaemic stroke events appeared approximately 10 years earlier in men than in women, and these rates remained higher in men than in women in all age groups. The gender difference was more marked for coronary heart disease than for ischaemic stroke. This may be taken into account when developing interventions and treatment strategies.

    Our objective is to explore the effect of curcumin on permeability of coronary artery and expression of related proteins in rat coronary atherosclerosis heart disease model. 45 healthy male Wistar rats of clean grade were selected and divided into treatment group, model control group and blank control group. The rats in the treatment group and model control group received high-fat diet for 12 weeks and intraperitoneal injection of VD3 to establish rat coronary atherosclerosis heart disease model. After modeling, the rats in the treatment group received gavage of 100 mg/(kg·d) curcimin, and the rats in the model control group and blank control group received gavage of 5 ml/(kg·d) distilled water, the intervention time was 4 weeks. After intervention, the rats were killed, and the hearts were dissected to obtain the samples of coronary artery. After embedding and frozen section, immunofluorescence method was used to detect the change of endarterium permeability in 3 groups, Western blot was used to detect matrix metalloproteinase-9 (MMP-9) and CD40L in coronary artery tissue, and enzyme linked immunosorbent assay (ELISA) was used to detect serum tumor necrosis factor-α (TNF-α) and C reaction protein (CRP). After modeling, compared with the blank control group, total cholesterol (TC), triglyceride (TG) and low density lipoprotein cholesterin (LDL-c) in the treatment group and model control group were significantly higher (Pcoronary artery in treatment group and model control group, indicating that the modeling was successful. Immunofluorescence showed that there was only a little fluorochrome permeability in artery in blank control group, there was some fluorochrome permeability in artery in the treatment group and there was a lot of fluorochrome permeability in artery in the model control group. MMP-9 and CD40L in coronary artery tissue in the model control group were significantly higher than the treatment group (Pcoronary artery tissue in the treatment group

    The myocardium assures the supply of oxygen to the body. The provision of oxygen to the myocardium by the coronary arteries is dependent on two key parameters: the coronary blood flow and the ability to extract oxygen from the arterial blood. Coronary artery disease is almost always the consequence of atherosclerosis and can lead to myocardial infarction.

  3. Coated stents to prevent restenosis in coronary heart disease

    Directory of Open Access Journals (Sweden)

    Hagen, Anja

    2005-11-01

    Full Text Available Background: In-stent-restenosis (ISR is considered to be an essential limiting factor of stenting in coronary heart disease (CHD. The development of coated stents has raised expectations on substantial lowering restenosis after stenting with decreasing the rate of restenosis and a reduction in the rate of clinical events. Objectives: The present analysis addresses the questions on medical effectiveness and cost-effectiveness of the use of various coated stent types in CHD. Methods: The literature was searched in December 2004 in the most relevant medical and economic databases. The medical evaluation was conducted on the basis of published RCT. The data from the studies regarding various angiographic, sonographic and clinical endpoints were checked for methodical quality and summarised in meta-analyses. Within the scope of economic evaluation the primary studies were analysed and modelling was performed, applying clinical effect estimates from the meta-analyses of the medical evaluation and current estimates of German costs. Results: Medical evaluation: Ten different stenttypes were used in the included 26 RCT. The results for heparin, silicon-carbide, carbon and PTFE coated stenttypes could not reveal any significant differences between the medical effectiveness of coated and uncoated stents. The application of sirolimus, paclitaxel, everolimus and 7-hexanoyltaxol eluting stents showed a significant lower restenosis at 6-9 months with decrease in the rate of restenosis for polymer-based sirolimus, paclitaxel and 7-hexanoyltaxol eluting stents. In contrast, the use of gold-coated and actinomycin-D eluting stents was associated with a significantly higher restenosis. The polymer-based sirolimus and paclitaxel eluting stents also showed a significant and considerable reduction in the rate of repeated percutaneous revascularisations at 6-12 months (3.5% vs. 19.7%; p<0.0001, RR=0.19 [95%CI: 0.11; 0.33] and 3.5% vs. 12.2%; p<0.0001, RR=0.30 [95%CI: 0

    The effects of rejection on coronary flow (CAF) in heart allografts are unclear, although previous evidence with cardiac imaging agents indicates impaired flow during advanced rejection. The purpose of this study was to measure CAF in heterotopically placed heart grafts. Lewis rats (LEW) received grafts from either syngeneic Lewis rats (LEW/LEW group) or allogeneic ACI rats (ACI/LEW group). CAF was measured in both the transplanted and native hearts with radiolabeled microspheres. Rejection was measured histologically (grades 0 [absent] to 4+ [severe]). In addition systemic blood pressure and cardiac outputs of the native hearts were determined with microspheres. Different animals were studied during relatively early (4 days) and late (6 days) rejection. Among the 4-day animals a cyclosporine-treated group was included (ACI/LEW CyA). In 6-day rats CAF in allografts was lower (0.56 +/- .06 ml/gm/min) compared with syngeneic grafts (1.72 +/- 0.4 ml/gm/min) (p less than 0.05). The CAF in the native hearts did not differ significantly but was higher than in the grafts in both groups. Heart rates were reduced in allografts (p less than 0.05). It is interesting that arterial pressure and cardiac output were significantly lower in animals bearing allogeneic than syngeneic grafts. In rats studied at 4 days graft CAF was lower than in the native heart in both the LEW/LEW and ACI/LEW groups, but there was no significant difference in behavior between groups. The same was true for a cyclosporine-treated group. Graft heart rates were similar in all 4-day rats

    Full Text Available Assessing multiple traditional risk factors improves prediction for late-life diseases, including coronary heart disease (CHD. It appears that non-traditional risk factors can also predict risk. The objective was to investigate contributions of non-traditional risk factors to coronary heart disease risk using a deficit accumulation approach.Community-dwelling adults with no known history of CHD (n = 2195, mean age 46.9±18.7 years, 51.8% women participated in the 1995 Nova Scotia Health Survey. Three risk factor indices were constructed to quantify the proportion of deficits present in individuals: 1 a 17-item Non-Traditional Risk Factor Index (e.g. sinusitis, arthritis; 2 a 9-item Traditional Risk Factor Index (e.g. hypertension, diabetes; and 3 a frailty index (25 items combined from the other two index measures. Ten-year risks of CHD events (defined as CHD-related hospitalization and CHD-related mortality were evaluated.The Non-Traditional Risk Factor Index, made up of health deficits unrelated to CHD, was independently associated with incident CHD events over 10 years after controlling for age, sex, and the Traditional Risk Factor Index [adjusted {adj.} Hazard Ratio {HR} = 1.31; Confidence Interval {CI} 1.14-1.51]. When all health deficits, both those related and unrelated to CHD, were included in a frailty index the corresponding adjusted hazard ratio was 1.61; CI 1.40-1.85.Both traditional and non-traditional risk factor indices are independently associated with incident CHD events. CHD risk assessment may benefit from consideration of general health information as well as from traditional risk factors.

    Cardiovascular disease (CVD) is now the leading cause of morbidity and mortality worldwide. Industrialization and economic growth have led to an unprecedented increment in the burden of CVD and their risk factors in less industrialized regions of the world. While there are abundant data on CVD and their risk factors from longitudinal cohort studies done in the West, good-quality data from South Asia are lacking. Several multi-institutional, observational, prospective registries, and epidemiologic cohorts in South Asia have been established to systematically evaluate the burden of CVD and their risk factors. The PINNACLE (Practice Innovation and Clinical Excellence) India Quality Improvement Program (PIQIP), the Kerala Acute Coronary Syndrome (ACS), and Trivandrum Heart Failure registries have focused on secondary prevention of CVD and performance measurement in both outpatient and inpatient settings, respectively. The Prospective Urban and Rural Epidemiology (PURE), Centre for Cardiometabolic Risk Reduction in South Asia (CARRS), and other epidemiologic and genetic studies have focused on primary prevention of CVD and evaluated variables such as environment, smoking, physical activity, health systems, food and nutrition policy, dietary consumption patterns, socioeconomic factors, and healthy neighborhoods. The international cardiovascular community has been responsive to a burgeoning cardiovascular disease burden in South Asia. Several collaborations have formed between the West (North America in particular) and South Asia to catalyze evidence-based and data-driven changes in the federal health policy in this part of the world to promote cardiovascular health and mitigate cardiovascular risk.

  8. Women, the menopause, hormone replacement therapy and coronary heart disease.

    Cardiovascular disease considerations are associated with the menopause. Despite a misconception that women have a minimal risk for coronary heart disease (CHD), it is the major cause of female deaths. This review highlights issues of hormone replacement therapy (HRT) and CHD in women. A woman under age 60, who suffers a myocardial infarction (MI), has a 2-year post-MI mortality of 28.9%; it is 19.6% in men. CHD and MI in women are subtle. In addition, female mortality from CHD increases after the menopause. The increased inflammatory risk factor status of women plays a role in development of atherosclerosis, before and after the menopause. Until after the menopause, women overall have a lower CHD mortality rate. Menopause is associated with unique symptoms, especially vasomotor ones; preexisting cardiovascular disease further exacerbates problems associated with the menopause. Use of HRT after the menopause is a major issue. Early menopause at age 39 years or younger and late menopause at age 56 years or older increase cardiovascular risk. HRT should not be prescribed for cardiovascular risk prevention, but when less than 10 years from menopause at a normal age, women can be reassured that cardiovascular risk from HRT is very low. Prescription of HRT should never be made only for cardiovascular risk reduction. However, when symptom-related and other indications are present, HRT is appropriate and well tolerated in the early years after menopause with onset at a normal age.

    Lipoprotein (a) [Lp (a)] is an established independent risk factor for premature myocardial infarction (MI)/coronary artery disease (CAD). The study was conducted to determine the value of Lp (a) in prediction of CAD or MI in the offspring at risk. A total of 160 subjects were investigated. Serum Lp (a) was measured by ELISA, serum total cholesterol, triglycerides (TG) and HDL-Cholesterol by enzymatic colorimetric methods using standard kits. Differences in levels of total Lp (a) and cholesterol were observed between patients and controls. Both Lp (a) (16.23+-1.95 mg/dL) and cholesterol (175.00+-7.60 mg/dL) of group A (patients) were higher than the corresponding controls. However an opposite trend in results was noted for serum HDL-Cholesterol in patients vs. controls.: Persons found to have elevated levels of Lp (a) should focus on controlling the known modifiable risk factor for heart disease, especially smoking, hypercholesterolemia, obesity, hypertension and sedentary life style.

    We analyzed the relationship between regional severity of emphysema, which was evaluated by three-dimensional fractal analysis (3D-FA) of Technegas SPECT images, and coronary heart disease (CHD). For 22 patients with emphysema who underwent Technegas SPECT, we followed up CHD events. The follow-up period was 5.4±0.5 (mean ±SD) years. We defined the upper-lung fractal dimension (U-FD) and lower-lung fractal dimension (L-FD) obtained with 3D-FA of Technegas SPECT images as the regional severity of emphysema. FD became greater with the progression of emphysematous change. During the follow-up period, CHD events occurred in 6 (27%) of the 22 patients. The ratio of U-FD to L-FD for patients with CHD events (0.87±0.22) was significantly smaller than for patients without CHD events (1.52±0.38) (p=0.0015). These findings suggest that severer emphysema in the lower lung indicates a higher risk of CHD than that in the upper lung. (author)

    Both depression and ischaemic heart disease are said to become the leading causes of morbidity and mortality in developing countries during the next two decades. The relationship between these two disorders has long been speculated but only recently addressed scientifically. A Medline search was conducted to obtain the articles that address the association between depressive disorders and coronary artery disease (CAD). Most studies following large cohorts over a period ranging from 4.5 to 27 years have shown that depression is associated with a significantly high risk of developing CAD. These studies also show that patients who have depression following myocardial infarction hat poorer prognosis on major cardiac end points like reoccurrence of myocardial infarction and death as compared to the non-depressed group. The psychosocial variables associated with depression like social isolation, acute and chronic stressful life events are also associated with increased risk of developing CAD. The mechanisms underlying this association between depression and CAD are unknown at present. The effectiveness of psychosocial interventions in reducing this increased risks have been demonstrated while the trials assessing the efficacy and safety of anti depressed drugs are underway. The implications of these finding are discussed in the context of developing countries. (author)

    Microcirculation disturbances have been associated to most of the cardiovascular risk factors as well as to multiple inflammatory diseases. However, whether these abnormalities are specifically augmented in patients with coronary heart disease is still unknown. We aimed to evaluate if there is a relationship between the presence of coronary heart disease and the existence of functional and structural capillary abnormalities evaluated in the cutaneous microcirculation by videocapillaroscopy. Two matched samples of 30 participants with and without coronary heart disease but with similar clinical and anthropometric characteristics were evaluated by videocapillaroscopy at the dorsal skin of the third finger of the non-dominant hand. We calculated basal capillary density as well as capillary density after a period of arterial and venous occlusion in order to evaluate functionality and maximum capillary density. We also measured capillary recruitment. Microvascular capillary density at rest was significantly lower in patients suffering from coronary heart disease than in controls. This fact was also found after dynamic tests (arterial and venous occlusion), suggesting functional impairments. Capillary recruitment of the samples was not different in our sample. In our study, patients with coronary heart disease exhibit functional and structural microvascular disturbances. Although this is a very preliminary study, these findings open the door for further studying the microvascular functionality in coronary patients and how it relates to the response to treatment and/or the prognosis of the disease.

  13. Modeling heart rate variability including the effect of sleep stages

    2016-02-01

    We propose a model for heart rate variability (HRV) of a healthy individual during sleep with the assumption that the heart rate variability is predominantly a random process. Autonomic nervous system activity has different properties during different sleep stages, and this affects many physiological systems including the cardiovascular system. Different properties of HRV can be observed during each particular sleep stage. We believe that taking into account the sleep architecture is crucial for modeling the human nighttime HRV. The stochastic model of HRV introduced by Kantelhardt et al. was used as the initial starting point. We studied the statistical properties of sleep in healthy adults, analyzing 30 polysomnographic recordings, which provided realistic information about sleep architecture. Next, we generated synthetic hypnograms and included them in the modeling of nighttime RR interval series. The results of standard HRV linear analysis and of nonlinear analysis (Shannon entropy, Poincaré plots, and multiscale multifractal analysis) show that—in comparison with real data—the HRV signals obtained from our model have very similar properties, in particular including the multifractal characteristics at different time scales. The model described in this paper is discussed in the context of normal sleep. However, its construction is such that it should allow to model heart rate variability in sleep disorders. This possibility is briefly discussed.

    Coronary magnetic resonance imaging (MRI) requires a correctly timed trigger delay derived from a scout cine scan to synchronize k-space acquisition with the quiescent period of the cardiac cycle. However, heart rate changes between breath-held cine and free-breathing coronary imaging may result in inaccurate timing errors. Additionally, the determined trigger delay may not reflect the period of minimal motion for both left and right coronary arteries or different segments. In this work, we present a whole-heart coronary imaging approach that allows flexible selection of the trigger delay timings by performing k-space sampling over an enlarged acquisition window. Our approach addresses coronary motion in an interactive manner by allowing the operator to determine the temporal window with minimal cardiac motion for each artery region. An electrocardiogram-gated, k-space segmented 3D radial stack-of-stars sequence that employs a custom rotation angle is developed. An interactive reconstruction and visualization platform is then employed to determine the subset of the enlarged acquisition window for minimal coronary motion. Coronary MRI was acquired on eight healthy subjects (5 male, mean age = 37 ± 18 years), where an enlarged acquisition window of 166-220 ms was set 50 ms prior to the scout-derived trigger delay. Coronary visualization and sharpness scores were compared between the standard 120 ms window set at the trigger delay, and those reconstructed using a manually adjusted window. The proposed method using manual adjustment was able to recover delineation of five mid and distal right coronary artery regions that were otherwise not visible from the standard window, and the sharpness scores improved in all coronary regions using the proposed method. This paper demonstrates the feasibility of a whole-heart coronary imaging approach that allows interactive selection of any subset of the enlarged acquisition window for a tailored reconstruction for each branch

    The aim of this report is to analyse trends in Italian cathlab activity between 2010 and 2015. Data were obtained from the national database of the Italian Society of Interventional Cardiology (GISE), which includes 97% of Italian cardiac catheterisation laboratories. The number of percutaneous coronary interventions (PCI) has remained relatively stable in the past five years. We have observed a significant increase in the number of primary PCI (pPCI) from 471.5 to 557.5 per million inhabitants with a consequent reduction of rescue primary PCI/fibrinolysis. One of the possible explanations for this might be the extensive networking for primary PCI and the adoption of Stent for Life initiatives in five regions. There has been a notably increased use of drug-eluting stents and, despite the fact that the introduction of bioabsorbable vascular scaffolds is recent, there is a slight, progressively positive trend. Invasive physiologic evaluation of coronary stenosis has markedly increased. Radial artery access has become the default option for PCI and for pPCI. In the last five years, TAVI procedures have doubled in number, while MitraClip and mitral repair procedures have shown a fivefold increase. Left atrial appendage (LAA) occlusion procedures have more than doubled in four years.

    The aim of this study was to determine whether post-traumatic stress disorder (PTSD) is associated with coronary heart disease (CHD) using a prospective twin study design and objective measures of CHD. It has long been hypothesized that PTSD increases the risk of CHD, but empirical evidence using objective measures is limited. We conducted a prospective study of middle-aged male twins from the Vietnam Era Twin Registry. Among twin pairs without self-reported CHD at baseline, we selected pairs discordant for a lifetime history of PTSD, pairs discordant for a lifetime history of major depression, and pairs without either condition. All underwent a clinic visit after a median follow-up of 13 years. Outcomes included clinical events (myocardial infarction, other hospitalizations for CHD and coronary revascularization) and quantitative measures of myocardial perfusion by [(13)N] ammonia positron emission tomography, including a stress total severity score and coronary flow reserve. A total of 562 twins (281 pairs) with a mean age of 42.6 years at baseline were included in this study. The incidence of CHD was more than double in twins with PTSD (22.6%) than in those without PTSD (8.9%; p Stress total severity score was significantly higher (+95%, p = 0.001) and coronary flow reserve was lower (-0.21, p = 0.02) in twins with PTSD than in those without PTSD, denoting worse myocardial perfusion. Associations were only mildly attenuated in 117 twin pairs discordant for PTSD. Among Vietnam-era veterans, PTSD is a risk factor for CHD. Copyright © 2013 American College of Cardiology Foundation.

    Guidelines stress the importance of risk factor management in patients with coronary heart disease (CHD). To evaluate whether guidelines on patient education in risk factor management are followed in clinical practice and to assess the contribution of nursing to risk factor management as perceived by patients with established CHD. Within three Dutch hospitals consecutive patients were identified after a first coronary-artery bypass graft, a first percutaneous transluminal coronary angioplasty or hospital admission for acute myocardial infarction or ischaemia (n=357). Data were collected through patient interviews at least 6 months after hospital admission. Among smokers, overweight patients, patients with hypertension, high cholesterol, and sedentary lifestyle, respectively 75, 36, 67, 61 and 49% reported that information on presence or management of these risk factors was provided. The proportion of patients informed by nurses ranged from 14% (lowering cholesterol) to 23% (increasing physical activity), while 55% (lowering cholesterol) to 71% (stop smoking) were informed by physicians. Many patients with established CHD and cardiovascular risk factors do not remember ever having received information about management of their risk factors. Clearly, there is a substantial potential to improve professionals' compliance to guidelines on risk factor management, including those on patient education. The perceived contribution of nurses to risk factor management is small compared to that of physicians and other caregivers. If risk factor management is felt to be a main responsibility of nurses, current nursing activities in this area should be reconsidered within an improved organisational structure.

    Adiponectin may influence the risk of coronary heart disease (CHD) independently of traditional cardiovascular risk factors. Because body composition and adiponectin levels vary by race, we examined the relationship of adiponectin with prevalent and incident CHD in a cohort of older Black and White adults. We conducted a cross-sectional and prospective cohort study at two U.S. clinical centers. Participants included 3075 well-functioning adults between ages 70 and 79 yr enrolled in the Health, Aging, and Body Composition study. Prevalent CHD was defined as history of myocardial infarction, coronary artery bypass graft, percutaneous coronary transluminal angioplasty, angina, or major electrocardiogram abnormalities. After excluding those with prevalent CHD, incident CHD was defined as hospitalized myocardial infarction or CHD death. At baseline, 602 participants (19.6%) had CHD. During 6 yr of follow-up, 262 (10.6%) incident CHD events occurred. Whites had higher median adiponectin than Blacks (12 vs. 8 microg/ml, P Blacks, a doubling of adiponectin was associated with a 40% higher risk of both prevalent CHD (odds ratio, 1.41; 95% confidence interval, 1.11-1.78) and incident CHD (hazards ratio, 1.37; 95% confidence interval, 1.01-1.87) after adjusting for explanatory variables. High circulating concentrations of adiponectin were associated with higher risk of CHD in older Blacks, even accounting for traditional CHD risk factors.

  2. Usefulness of cardiorespiratory fitness to predict coronary heart disease risk independent of physical activity.

    Science.gov (United States)

    Williams, Paul T

    2010-07-15

    Cardiorespiratory fitness has often been interpreted as a surrogate measurement of physical activity rather than an independent coronary heart disease (CHD) risk factor per se. Fitness is also known to be highly heritable, however, and rats bred selectively for treadmill endurance have low CHD risk phenotypes even in the absence of physical activity. Therefore, I assessed whether cardiorespiratory fitness predicted CHD independent of physical activity in 29,721 men followed prospectively for 7.7 years as part of the National Runners' Health Study. Specifically, CHD deaths and incident participant-reported physician-diagnosed myocardial infarction, revascularization procedures (coronary artery bypass grafting and percutaneous coronary intervention), and angina pectoris during follow-up were compared to baseline cardiorespiratory fitness (10-km footrace performance, meters/second). Nonfatal end points for the 80% of these men who provided follow-up questionnaires included 121 nonfatal myocardial infarctions, 317 revascularization procedures, and 81 angina pectora. The National Death Index identified 44 CHD deaths. Per meter/second increment in baseline fitness, men's risks decreased 54% for nonfatal myocardial infarction (p fitness is a CHD risk factor, largely independent of physical activity, which warrants clinical screening.

    To determine whether the 9p21 SNP association with coronary heart disease is modified by other classical or novel risk markers. The 9p21 SNP (rs10757274) and multiple risk markers were measured in the Atherosclerosis Risk in Communities Study, and incident coronary disease events were ascertained. Effect modification (interaction) of the 9p21 SNP with risk markers was tested in Cox proportional hazard regression models. The incidence rates of coronary heart disease per 1000 person-years were 14.4, 17.0, and 18.7 for AA, AG, and GG genotypes, yielding hazard ratios of 1.0, 1.20 (95% CI = 1.07-1.36), and 1.34 (95% CI = 1.16-1.53). There was no meaningful evidence of an interaction (all p-interaction > 0.04) between 9p21 SNP and any of 14 other risk markers for coronary heart disease. These included novel markers not previously explored for 9p21 interaction (e.g., cardiac troponin T and N-terminal pro-brain natriuretic peptide). Our study extends evidence that the 9p21 SNP association with coronary heart disease is not modified by classical or novel risk markers. Our findings therefore rule out additional plausible pathways by which 9p21 might have increased coronary heart disease risk. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

    Clinicians often use the term "hibernating myocardium" in reference to patients with ischemic heart disease and decreased function within viable myocardial regions. Because the term is a descriptor of nature's process of torpor, we provide a comparison of the adaptations observed in both conditions. In nature, hearts from hibernating animals undergo a shift in substrate preference in favor of fatty acids, while preserving glucose uptake and glycogen. Expression of electron transport chain proteins in mitochondria is decreased while antioxidant proteins including uncoupling protein-2 are increased. Similarly, hibernating hearts from patients have a comparable metabolic signature, with increased glucose uptake and glycogen accumulation and decreased oxygen consumption. In contrast to nature however, patients with hibernating hearts are at increased risk for arrhythmias, and contractility does not fully recover following revascularization. Clearly, additional interventions need to be advanced in patients with coronary artery disease and hibernating myocardium to prevent refractory heart failure.

    Most evidence on the efficacy of intensive preventive programs of secondary prevention of coronary diseases comes from Anglo-Saxon countries and effectiveness remains controversial. We have scarce information about the efficacy of these types of programs in Spain. In the present analysis we show the results of the ICAR (Intervención en la Comunidad de Alto Riesgo coronario) study, aimed to analyze the efficacy of an intensive preventive program primary care based in reducing the cardiovascular recurrences and mortality in patients with coronary heart disease. We designed a randomized clinical trial, multicenter and community based, which included 23 health care areas in Catalonia, Spain. We followed for 5 years 2 cohorts of patients with coronary heart disease, aged 30-80 years. The intervention group was quarterly examined by their general practitioner, who adjusted treatments to control their cardiovascular risk factors thoroughly and reinforced life style behaviours. In order to do that, patient's weight and blood pressure were determined in each visit and laboratory test carried out twice a year. Patients in the control group received the usual care. In order to analyze the effect of the intervention cardiovascular recurrences and mortality were registered. We included 983 patients. Mean (standard deviation) age was 64 (10) and 74.5% were men. During the follow-up 235 patients suffered some non-fatal cardiovascular recurrence (109 vs 126 in the control and intervention group, respectively; p = 0.84), and 45 died from cardiovascular recurrences (23 vs 22, respectively; p = 0.57). Adjusted hazard ratio of cardiovascular event and total mortality, for the intervention group were 1.01 (95% confidence interval, 0.74-1.39), and 0.92 (95% confidence interval, 0.54-1.56), respectively. The implementation of an intensive secondary prevention program based on periodical reminds to patients with stable coronary heart disease to attend their general practitioners did not

    The goals of this systematic analysis are to determine the association between family history of coronary heart disease (CHD) and markers of subclinical cardiovascular disease as well as to discuss the inclusion of CHD family history in the frequently used coronary risk prediction algorithms. Individuals with a family history of CHD are at high risk for developing atherosclerosis and events related to CHD, regardless of the presence of other coronary risk factors. They form a target population that might benefit from primary prevention strategies; however, family history data is not a part of the frequently used risk prediction algorithms. Medline and PubMed databases were searched for all studies evaluating the relationship between measures of subclinical atherosclerosis and family history of CHD, published till June 2010. Thirty-two studies met the above criteria and were included in this review. Coronary artery calcium, carotid intima thickness, vascular function, and inflammatory markers including C reactive protein, fibrinogen, and D-dimer were used as measures of subclinical atherosclerosis. Studies differed in design, demographic data of the population, techniques and validation of family history information. Most studies established a statistically significant relationship between the above markers and family history of CAD; further, the association was noted to be independent of traditional risk factors. Family history of CAD is associated with markers of subclinical atherosclerosis, and this relationship remains statistically significant after adjusting for traditional risk factors. The above data suggest these individuals should be considered strongly as candidates for assessment of subclinical CVD to further refine risk and treatment goals. Copyright © 2013.

    Objective: To investigate risk factors of coronary heart disease (CHD) in medical diagnostic X-ray workers in China, especially the relationship of CHD with occupational irradiation. Methods: A 1:2 matched case-control study was carried out. The study subjects consisted of 112 pair-matched cases and controls coming from different hospitals in China. Information about occupational and non-occupational risk factors obtained by interviewing every subjects personally. Individual doses were estimated by normalized work load method. SAS 6.12 software conditional Logistic regression method was applied to data analysis. Results: Variables such as family history of CHD (OR=17.298, P = 0.0001), history of hypertension (OR = 6.172, P = 0.0003), overweight (OR = 2.679, P = 0.0150), physical exercises (OR = 0.421, P0.0333), diabetes (OR = 7.823, P = 0.0200), radiation protection condition (OR = 3.992, P 0.0027), and accumulated radiation dose (OR = 1.612, P 0.0454) were included in the last model. Conclusions: For the medical diagnostic X-ray workers, family history of coronary heart disease, history of hypertension, diabetes, etc. are the main risk factors of CHD, and occupational exposure may be a potential risk factor. As for the mechanism, further studies are needed

    Full Text Available Abstract Background The coronary artery calcium (CAC score is an independent predictor of coronary heart disease. We sought to combine information from the CAC score with information from conventional cardiac risk factors to produce post-test risk estimates, and to determine whether the score may add clinically useful information. Methods We measured the independent cross-sectional associations between conventional cardiac risk factors and the CAC score among asymptomatic persons referred for non-contrast electron beam computed tomography. Using the resulting multivariable models and published CAC score-specific relative risk estimates, we estimated post-test coronary heart disease risk in a number of different scenarios. Results Among 9341 asymptomatic study participants (age 35–88 years, 40% female, we found that conventional coronary heart disease risk factors including age, male sex, self-reported hypertension, diabetes and high cholesterol were independent predictors of the CAC score, and we used the resulting multivariable models for predicting post-test risk in a variety of scenarios. Our models predicted, for example, that a 60-year-old non-smoking non-diabetic women with hypertension and high cholesterol would have a 47% chance of having a CAC score of zero, reducing her 10-year risk estimate from 15% (per Framingham to 6–9%; if her score were over 100, however (a 17% chance, her risk estimate would be markedly higher (25–51% in 10 years. In low risk scenarios, the CAC score is very likely to be zero or low, and unlikely to change management. Conclusion Combining information from the CAC score with information from conventional risk factors can change assessment of coronary heart disease risk to an extent that may be clinically important, especially when the pre-test 10-year risk estimate is intermediate. The attached spreadsheet makes these calculations easy.

    Full Text Available BACKGROUND: Coronary heart disease (CHD mortality rates have been decreasing in Iceland since the 1980s, largely reflecting improvements in cardiovascular risk factors. The purpose of this study was to predict future CHD mortality in Iceland based on potential risk factor trends. METHODS AND FINDINGS: The previously validated IMPACT model was used to predict changes in CHD mortality between 2010 and 2040 among the projected population of Iceland aged 25-74. Calculations were based on combining: i data on population numbers and projections (Statistics Iceland, ii population risk factor levels and projections (Refine Reykjavik study, and iii effectiveness of specific risk factor reductions (published meta-analyses. Projections for three contrasting scenarios were compared: (1 If the historical risk factor trends of past 30 years were to continue, the declining death rates of past decades would level off, reflecting population ageing. (2 If recent trends in risk factors (past 5 years continue, this would result in a death rate increasing from 49 to 70 per 100,000. This would reflect a recent plateau in previously falling cholesterol levels and recent rapid increases in obesity and diabetes prevalence. 3 Assuming that in 2040 the entire population enjoys optimal risk factor levels observed in low risk cohorts, this would prevent almost all premature CHD deaths before 2040. CONCLUSIONS: The potential increase in CHD deaths with recent trends in risk factor levels is alarming both for Iceland and probably for comparable Western populations. However, our results show considerable room for reducing CHD mortality. Achieving the best case scenario could eradicate premature CHD deaths by 2040. Public health policy interventions based on these predictions may provide a cost effective means of reducing CHD mortality in the future.

    Objective: The purpose of the study was to evaluate the relationship between 201 Tl lung/heart ratio during exercise and left ventricular diastolic function and its diagnostic value on severity of coronary artery disease. Methods: One hundred and two patients with documented coronary artery disease were divided into three groups, including no hypertension, hypertension without or with left ventricular hypertrophy groups. Exercise/delay 201 Tl myocardial perfusion tomography was performed on all patients included. Lung/heart ratio was defined on the anterior planar image obtained during exercise tomography. Results: The lung/heart ratios during exercise in no hypertension (0.43 +- 0.09, P 0.05). The lung/heart ratios of multi-vessel disease subgroup in no hypertension (0.46 +- 0.10 vs 0.40 +- 0.09, P 0.05). When lung/heart ratio was≥0.45, the sensitivities for predicting the presence of multi-vessel disease were 82%, 90%, 40% and specificities were 75%, 75%, 45%, respectively, in no hypertension, hypertension without and with hypertrophy groups. In no hypertension (r=0.402, P 0.05). In no hypertension (r=-0.413, P<0.01), hypertension without (r=-0.662, P<0.01) and with hypertrophy groups (r=-0.408, P<0.05), lung/heart ratios all showed a significant reverse correlation with correspondent E/A ratios. Conclusions: The exercise lung/heart ratios has a better diagnostic value for multi-vessel disease and left ventricular diastolic function abnormalities of coronary artery disease with or without hypertension, but not for multi-vessel disease in hypertension patients complicated with myocardial hypertrophy

    In conclusion, heart rate is a marker of risk but is not a risk factor and/or a target of therapy in patients with stable coronary artery disease and preserved ventricular systolic function. Standard doses of ivabradine are indicated for treatment of angina as an alternative or in addition to beta-blockers, but should not be administered in association with CYP3A4 inhibitors or heart rate-lowering calcium-channel blockers.

    To assess survival in people who are at apparent high risk who do not develop coronary heart disease ("unwarranted survivals") and mortality in people at low risk who die from the disease ("anomalous deaths") and the extent to which these outcomes are explained by other, less visible, risk factors. Prospective general population survey. Renfrew and Paisley, Scotland. 6068 men aged 45-64 years at screening in 1972-6, allocated to "visible" risk groups on the basis of body mass index and smoking. Survival and death from coronary heart disease by age 70 years. Visible risk was a good predictor of mortality: 13% (45) of men at low risk and 45% (86) of men at high risk had died by age 70 years. Of these deaths, 12 (4%) and 44 (23%), respectively, were from coronary heart disease. In the group at low visible risk other less visible risk factors accounted for increased risk in 83% (10/12) of men who died from coronary heart disease and 29% (84/292) of men who survived. In the high risk group 81/107 who survived (76%) and 19/44 (43%) who died from coronary heart disease had lower risk after other factors were considered. Different risk factors modified risk (beyond smoking and body mass index) in the two groups. Among men at low visible risk, poor respiratory function, diabetes, previous coronary heart disease, and socioeconomic deprivation modified risk. Among men at high visible risk, height and cholesterol concentration modified risk. Differences in survival between these extreme risk groups are dramatic. Health promotion messages would be more credible if they discussed anomalies and the limits of prediction of coronary disease at an individual level.

    Full Text Available Background/Aim. Recent studies indicate that the prevalence of diabetes mellitus (DM type 2 is increasing in the world. Chronic hyperglycemia in DM is associated with a long term damage, dysfunction and failure of various organs, especially retina, kidney, nerves and, in addition, with an increased risk of cardiovasclar disease. For a long time the illness has been unknown. Early diagnosis of diabetes could suspend the development of diabetic complications. The aim of the study was to establish risk for the development of coronary disease in the patients evaluated by the use of new diagnostic criteria for DM. Methods. The study included 930 participants without diagnosis of DM, hypertension, dyslipidemia, nor coronary heart disease two years before the study. The patients went through measuring of fasting plasma glycemia, erythrocytes, hematocrit, cholesterol, triglycerides, high-density lipoprotein cholesterol (HDL-C, low-density lipoprotein cholesterol, aspartate aminotransferase and alanine aminotransferase. In the group with hyperglycemia the 2-hour oral glucose tolerance test was performed. We analyzed ECG and made blood pressure monitoring, and also measured body mass, height, waist and hip circumference. We analyzed life style, especially smoking, and exercise and family history. Results. Diabetes prevalence was 2.68%, and prevalences of impaired fasting glucose, impaired glucose tolerance and DM were 12.15%. Average age of males and females was 38 and 45 years, respectively. In the healthy population there was higher frequency of smokers (55% vs 42%, but in the population with hyperglycemia there were more obesity (23% vs 10.5%, hypertension (39% vs 9%, hypercholesterolemia (76% vs 44.1%, lower HDL-C (52.2% vs 25.7%. Cummulative risk factor in healthy subjects, and those with hyperglycemia were 5.6% and 14%, respectively. Conclusion. Subjects with hyperglicemia without diagnosis of DM have higher risk factors for coronary heart disease.

    Coronary heart disease (CHD) is the single most common cause of death globally. However, with falling CHD mortality rates, an increasing number of people live with CHD and may need support to manage their symptoms and improve prognosis. Cardiac rehabilitation is a complex multifaceted intervention which aims to improve the health outcomes of people with CHD. Cardiac rehabilitation consists of three core modalities: education, exercise training and psychological support. This is an update of a Cochrane systematic review previously published in 2011, which aims to investigate the specific impact of the educational component of cardiac rehabilitation. 1. To assess the effects of patient education delivered as part of cardiac rehabilitation, compared with usual care on mortality, morbidity, health-related quality of life (HRQoL) and healthcare costs in patients with CHD.2. To explore the potential study level predictors of the effects of patient education in patients with CHD (e.g. individual versus group intervention, timing with respect to index cardiac event). We updated searches from the previous Cochrane review, by searching the Cochrane Central Register of Controlled Trials (CENTRAL) (Cochrane Library, Issue 6, 2016), MEDLINE (Ovid), Embase (Ovid), PsycINFO (Ovid) and CINAHL (EBSCO) in June 2016.

    A high circulating concentration of interleukin 6 is associated with increased risk of coronary heart disease. Blockade of the interleukin-6 receptor (IL6R) with a monoclonal antibody (tocilizumab) licensed for treatment of rheumatoid arthritis reduces systemic and articular inflammation. However, whether IL6R blockade also reduces risk of coronary heart disease is unknown. Applying the mendelian randomisation principle, we used single nucleotide polymorphisms (SNPs) in the gene IL6R to evaluate the likely efficacy and safety of IL6R inhibition for primary prevention of coronary heart disease. We compared genetic findings with the effects of tocilizumab reported in randomised trials in patients with rheumatoid arthritis. In 40 studies including up to 133,449 individuals, an IL6R SNP (rs7529229) marking a non-synonymous IL6R variant (rs8192284; p.Asp358Ala) was associated with increased circulating log interleukin-6 concentration (increase per allele 9·45%, 95% CI 8·34-10·57) as well as reduced C-reactive protein (decrease per allele 8·35%, 95% CI 7·31-9·38) and fibrinogen concentrations (decrease per allele 0·85%, 95% CI 0·60-1·10). This pattern of effects was consistent with IL6R blockade from infusions of tocilizumab (4-8 mg/kg every 4 weeks) in patients with rheumatoid arthritis studied in randomised trials. In 25,458 coronary heart disease cases and 100,740 controls, the IL6R rs7529229 SNP was associated with a decreased odds of coronary heart disease events (per allele odds ratio 0·95, 95% CI 0·93-0·97, p=1·53×10(-5)). On the basis of genetic evidence in human beings, IL6R signalling seems to have a causal role in development of coronary heart disease. IL6R blockade could provide a novel therapeutic approach to prevention of coronary heart disease that warrants testing in suitably powered randomised trials. Genetic studies in populations could be used more widely to help to validate and prioritise novel drug targets or to repurpose existing

    The aim of the study is the assessment of the methodology for the C-TIMI frame count by Gibson for easy and fast determination of the coronary blood flow during a selective coronary angiography. 75 patient have been studied with one-branch affection of the coronary arteries. The criteria for exclusion are: myocardial hypertrophy, valve lesions, myocardial infarction and dyslipidemia. Depending of the characteristics of the coronary stenotic changes, the patients have been divided into two groups: 1) Patients with 'ordinary' stenosis of the coronary artery and 2) Patients with 'complex' stenosis. The severity of the stenotic changes in percents is the same for the two groups - 78%±13% vs 81±12%, respectively. In the first group a pronounced correlation is observed between the severity of the coronary stenosis and the slowing of the coronary blood flow. The 'threshold' stenotic level is 89%. In the second group the lowest value of the coronary stenosis is 73% (p>0.01 vs group 1). No correlation is observed between the severity of the coronary stenosis and the slowing of the coronary blood flow. A conclusion is made that the Gibson method for the assessment of the blood flow is convenient for the daily practice not only for the assessment of the significance of the coronary changes, but also for fast analysis of the achieved reconstruction of the coronary arteries after angioplasty. Additional studies of the significance of the different signs of 'complexity' of the coronary stenosis for the slowing of the blood flow are necessary

    Current recommendations prescribe that every adult should accumulate 30 minutes or more of moderate physical activity in leisure time, preferably every day of the week. The optimal intensity, duration, and frequency still have to be established. The aim of this study was to examine the impact of intensity versus duration of cycling on all-cause and coronary heart disease mortality. Relative intensity and duration of cycling were recorded in 5106 apparently healthy men and women aged 21-90 years drawn from the general population of Copenhagen, and followed for an average of 18 years. Total number of deaths during follow-up was 1172, of these 146 were coronary heart disease deaths. For both sexes we found a significant inverse association between cycling intensity and risk of all-cause and coronary heart disease death, but only a weak association with cycling duration. The difference in expected lifetime in relation to intensity of cycling was calculated. Men with fast intensity cycling survived 5.3 years longer, and men with average intensity 2.9 years longer than men with slow cycling intensity. For women the figures were 3.9 and 2.2 years longer, respectively. Our findings indicate that the relative intensity, and not the duration of cycling, is of more importance in relation to all-cause and coronary heart disease mortality. Thus our general recommendations to all adults would be that brisk cycling is preferable to slow.

    This article is devoted to the problems of diagnostics of coronary artery tortuosity phenomenon. Given the lack of literature about the role of phenomenon tortuosity of coronary arteries in the genesis of ischemic myocardial damage, the purpose of study was to determine the clinical relevance as well as necessity for prevention and treatment of this vascular anomaly. Therefore were analyzed medical history, laboratory and clinical database as well as data functional studies of the heart and cardiovascular system in 1404 patients which were divided into four groups on the results of coronary angiography. The results of the study indicate tortuosity of coronary arteries may be independent and additional burdening factor in the development of ischemic heart disease.

    To measure the frequency of genotypes of the HFE (haemochromatosis) gene in patients recruited to the west of Scotland coronary prevention study (WOSCOPS), and relate them to the subsequent occurrence of coronary clinical events. Nested case-control study, drawing samples of DNA from the biological bank of a cohort study. Men aged 45-64 years in 1989, with moderate hypercholesterolaemia and no evidence of coronary heart disease at baseline. Follow up for a mean period of 4.9 years. Typing for C282Y and H63D mutations of the HFE gene in 482 subjects with a subsequent coronary event and 1104 without an event. The C282Y mutation was present in 81 of 482 cases (16.8%) and 182 of 1104 controls (16.5%). Comparing the prevalence of gene mutations in the cases and controls, there were no significant differences. The hazard ratio for C282Y heterozygotes was 1.03 (95% confidence interval (CI) 0.77 to 1.36) and for C282Y/H63D compound heterozygotes 1.04 (95% CI 0.50 to 2.14). Prespecified subgroup analyses of the pravastatin, placebo, smoking, and non-smoking groups showed no significant differences between cases and controls. Repeating the analyses after adjusting for possible confounding factors produced no change in the results. In a population of moderately hypercholesterolaemic middle aged Scottish men who did not have any evidence of coronary heart disease at baseline, the presence of a C282Y mutation in the HFE gene did not predict the occurrence of coronary events over a mean follow up of 4.9 years.

    Echocardiography, multidetector computed tomography, magnetic resonance imaging, and nuclear cardiology can all help prevent coronary heart disease. Echocardiography can identify asymptomatic individuals who are at risk of coronary disease and who should receive aggressive preventative therapy by providing data on the carotid intima-media thickness, arterial stiffness and flow-mediated dilatation of the brachial artery. The calcium score is an independent predictor of cardiac events that influences clinical risk scores such as the Framingham risk score. By using multidetector computed tomography or magnetic resonance imaging for coronary angiography, it is possible to visualize both the lumen and vessel walls of coronary arteries and to discriminate between calcified and noncalcified atherosclerotic plaque before invasive coronary angiography is performed. With nuclear cardiology, the functional effects of atherosclerotic lesions can be evaluated by assessing perfusion and ventricular function simultaneously

  7. The decline and rise of coronary heart disease: understanding public health catastrophism.

    2013-07-01

    The decline of coronary heart disease mortality in the United States and Western Europe is one of the great accomplishments of modern public health and medicine. Cardiologists and cardiovascular epidemiologists have devoted significant effort to disease surveillance and epidemiological modeling to understand its causes. One unanticipated outcome of these efforts has been the detection of early warnings that the decline had slowed, plateaued, or even reversed. These subtle signs have been interpreted as evidence of an impending public health catastrophe. This article traces the history of research on coronary heart disease decline and resurgence and situates it in broader narratives of public health catastrophism. Juxtaposing the coronary heart disease literature alongside the narratives of emerging and reemerging infectious disease helps to identify patterns in how public health researchers create data and craft them into powerful narratives of progress or pessimism. These narratives, in turn, shape public health policy.

    Full Text Available The coronary heart disease is one of desease leading to the sudden death. This is the reason why online monitoring system is urgently needed to monitor the patients with coronary heart disease. This paper proposse the system with an algorithm which is developed from signal identification of ST elevation. The medical record in this system is measured by a new wireless ECG development and followed Zigbee standard. If the system detects the possibility of disturbance in cardiac function, then soon, an alarm signal is send to the server at the hospital, in order that an intensive first aid can be given immediately. Based on the testing results, the level of success of an online monitoring system is possible to reach 100% if the patient does not make any moving around. It is expected that the application of this system will reduce the sudden death for patients at hospital with coronary heart disease.

  9. Heart Failure with Transient Left Bundle Branch Block in the Setting of Left Coronary Fistula

    2011-01-01

    Full Text Available Coronary arterial fistulas are rare communications between vessels or chambers of the heart. Although cardiac symptoms associated with fistulas are well described, fistulas are seldom considered in the differential diagnosis of acute myocardial ischemia. We describe the case of a 64-year-old man who presented with left shoulder pain, signs of heart failure, and a new left bundle branch block (LBBB. Cardiac catheterization revealed a small left anterior descending (LAD-to-pulmonary artery (PA fistula. Diuresis led to subjective improvement of the patient's symptoms and within several days the LBBB resolved. We hypothesize that the coronary fistula in this patient contributed to transient ischemia of the LAD territory through a coronary steal mechanism. We elected to observe rather than repair the fistula, as his symptoms and ECG changes resolved with treatment of his heart failure.

    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, Pcoronary artery disease patients.

    2013-01-01

    The advent of universal health care coverage in the United States and the use of electronic health records can make the medical record a disease surveillance tool. The objective of our study was to identify criteria that accurately categorize acute coronary and heart failure events by using electronic health record data exclusively so that the medical record can be used for surveillance without manual record review. We serially compared 3 computer algorithms to manual record review. The first 2 algorithms relied on ICD-9-CM (International Classification of Diseases, 9th Revision, Clinical Modification) codes, troponin levels, electrocardiogram (ECG) data, and echocardiograph data. The third algorithm relied on a detailed coding system, Intelligent Medical Objects, Inc., (IMO) interface terminology, troponin levels, and echocardiograph data. Cohen's κ for the initial algorithm was 0.47 (95% confidence interval [CI], 0.41-0.54). Cohen's κ was 0.61 (95% CI, 0.55-0.68) for the second algorithm. Cohen's κ for the third algorithm was 0.99 (95% CI, 0.98-1.00). Electronic medical record data are sufficient to categorize coronary heart disease and heart failure events without manual record review. However, only moderate agreement with medical record review can be achieved when the classification is based on 4-digit ICD-9-CM codes because ICD-9-CM 410.9 includes myocardial infarction with elevation of the ST segment on ECG (STEMI) and myocardial infarction without elevation of the ST segment on ECG (nSTEMI). Nearly perfect agreement can be achieved using IMO interface terminology, a more detailed coding system that tracks to ICD9, ICD10 (International Classification of Diseases, Tenth Revision, Clinical Modification), and SnoMED-CT (Systematized Nomenclature of Medicine - Clinical Terms).

    Structure-metabolic changes of collagen fibers (CF) in atherosclerosis plaques of the coronary arteries in the conditions of ischemic heart disease (IHD) have been studied. Segments of the coronary arteries were received from 68 men after a coronary artery bypass grafting. CF was study with using of the Van Gieson's and the Masson's methods. Histologic slices were studied by polarization microscopy. The atherosclerosis plaques with IHD were notable for lipidosis of CF. We've suspected lipidosis of CF is a crucial factor for the development of atherosclerosis plaques instability. Evident lipidosis of CF was attended with destructive changes probably resulted in accumulation of atheromatous mass in atherosclerosis plaques.

    The aim of this study was to find the differences between premorbid and present self-image in patients with coronary heart disease. 70 patients with stable coronary heart disease treated at the Internal Medicine Department of the Military Hospital in Lublin and 70 healthy controls were studied. Mean age of the investigated patients was 53.11 years. 77% of the studied patients were city inhabitants and 23% were countryside dwellers. Subjects were studied with the use of the State-Trait Anxiety Inventory, by the Adjective Check List (ACL) and a questionnaire designed especially for the study of sociodemographic data of the investigated patients. Premorbid and present self-images were compared with the use of the ANOVA test. Our results showed that there are statistically significant differences between premorbid and present self-image in the perception of patients with coronary heart disease. 1. In present self-image, compared to the premorbid one, patients with coronary heart disease have low self-esteem, greater fear about the future, low endurance in performing tasks, they are less enterprising, have lower ability to overcome stress, they are more dependent and have a greater need to look for safety. 2. Women with coronary heart disease perceive themselves as having low self-esteem, low self-trust, more difficulties in overcoming stress and a lower ability to understand other people's behaviour as compared to the time before the disease. 3. Men with coronary heart disease perceive themselves as having less endurance, being less enterprising, having a negative attitude towards themselves and other people and being more dependant compared to the time before the illness.

    Full Text Available Abstract Background Magnitudes, geographic and racial variation in trends in coronary heart disease (CHD mortality within the US require updating for health services and health disparities research. Therefore the aim of this study is to present data on these trends through 2007. Methods Data for CHD were analyzed using the US mortality files for 1999–2007 obtained from the US Centers for Disease Control and Prevention. Age-adjusted annual death rates were computed for non-Hispanic African Americans (AA and European Americans (EA aged 35–84 years. The direct method was used to standardize rates by age, using the 2000 US standard population. Joinpoint regression models were used to evaluate trends, expressed as annual percent change (APC. Results For both AA men and women the magnitude in CHD mortality is higher compared to EA men and women, respectively. Between 1999 and 2007 the rate declined both in AA and in EA of both sexes in every geographic division; however, relative declines varied. For example, among men, relative average annual declines ranged from 3.2% to 4.7% in AA and from 4.4% to 5.5% in EA among geographic divisions. In women, rates declined more in later years of the decade and in women over 54 years. In 2007, age-adjusted death rate per 100,000 for CHD ranged from 93 in EA women in New England to 345 in AA men in the East North Central division. In EA, areas near the Ohio and lower Mississippi Rivers had above average rates. Disparities in trends by urbanization level were also found. For AA in the East North Central division, the APC was similar in large central metro (−4.2, large fringe metro (−4.3, medium metro urbanization strata (−4.4, and small metro (−3.9. APC was somewhat higher in the micropolitan/non-metro (−5.3, and especially the non-core/non-metro (−6.5. For EA in the East South Central division, the APC was higher in large central metro (−5.3, large fringe metro (−4.3 and medium metro

    The clinical presentation of panic disorder and panic attack overlaps many symptoms typically experienced in coronary heart disease (CHD). Etiological links between panic disorder and CHD are controversial and remain largely tenuous. This systematic review aims to pool together data regarding panic disorder with respect to incident CHD or myocardial infarction. Electronic databases (MEDLINE, EMBASE, PsycINFO and SCOPUS) will be searched using a search strategy exploding the topics for CHD and panic disorder. Authors and reference lists of included studies will also be contacted to identify additional published and unpublished studies. Eligibility criteria are as follows: persons without CHD who meet criteria for panic disorder, panic attack, anxiety neurosis or elevated panic disorder symptoms; Comparison: persons without CHD who do not meet criteria for panic disorder, panic attack, anxiety neurosis or elevated panic disorder symptoms; verified fatal and non-fatal CHD at follow-up; including coronary revascularization procedure, coronary artery disease, and myocardial infarction. Studies adopting self-report CHD will be ineligible. Screening will be undertaken by two independent reviewers with disagreements resolved through discussion. Data extraction will include original data specified as hazard ratios, risk ratios, and original cell data if available. Risk of bias assessment will be undertaken by two independent reviewers. Meta-analytic methods will be used to synthesize the data collected relating to the CHD outcomes with Cochrane Review Manager 5.3. This systematic review aims to clarify whether panic disorder is associated with elevated risk for subsequent CHD. An evaluation of the etiological links between panic disorder with incident CHD might inform evidence-based clinical practice and policy concerning triaging chest pain patients, diagnostic assessment, and psychiatric intervention with panic disorder patients.

    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.

    Full Text Available We established the Leipzig (LIFE Heart Study, a biobank and database of patients with different stages of coronary artery disease (CAD for studies of clinical, metabolic, cellular and genetic factors of cardiovascular diseases.The Leipzig (LIFE Heart Study (NCT00497887 is an ongoing observational angiographic study including subjects with different entities of CAD. Cohort 1, patients undergoing first-time diagnostic coronary angiography due to suspected stable CAD with previously untreated coronary arteries. Cohort 2, patients with acute myocardial infarction (MI requiring percutaneous revascularization. Cohort 3, patients with known left main coronary artery disease (LMCAD.We present preliminary results of demographics and phenotyping based on a 4-years analysis of a total of 3,165 subjects. Cohort 1 (n=2,274 shows the typical distribution of elective coronary angiography cohorts with 43% cases with obstructive CAD and 37% normal angiograms. Cohorts 2 and 3 consist of 590 and 301 subjects, respectively, adding patients with severe forms of CAD. The suitability of the database and biobank to perform association studies was confirmed by replication of the CAD susceptibility locus on chromosome 9p21 (OR per allele: 1.55 (any CAD, 1.54 (MI, 1.74 (LMCAD, p<10(-6, respectively. A novel finding was that patients with LMCAD had a stronger association with 9p21 than patients with obstructive CAD without LMCAD (OR 1.22, p=0.042. In contrast, 9p21 did not associate with myocardial infarction in excess of stable CAD.The Leipzig (LIFE Heart Study provides a basis to identify molecular targets related to atherogenesis and associated metabolic disorders. The study may contribute to an improvement of individual prediction, prevention, and treatment of CAD.

  3. Usefulness of Beta blockade in contemporary management of patients with stable coronary heart disease.

    2014-11-15

    Considerable progress has been made over the last few decades in the management of clinically stable coronary heart disease (SCHD), including improvements in interventions (e.g., percutaneous revascularization), pharmacological management, and risk factor control (e.g., smoking, diet, activity level, hypercholesterolemia, hypertension). Although β blockers have long been used for the treatment of SCHD, their efficacy was established in the era before widespread use of reperfusion interventions, modern medical therapy (e.g., angiotensin-converting enzyme inhibitors, angiotensin receptor blockers), or preventive treatments (e.g., aspirin, statins). On the basis of these older data, β blockers are assumed beneficial, and their use has been extrapolated beyond patients with heart failure and previous myocardial infarction, which provided the best evidence for efficacy. However, there are no randomized clinical trials demonstrating that β blockers decrease clinical events in patients with SCHD in the modern era. Furthermore, these agents are associated with weight gain, problems with glycemic control, fatigue, and bronchospasm, underscoring the fact that their use is not without risk. In conclusion, data are currently lacking to support the widespread use of β blockers for all SCHD patients, but contemporary data suggest that they be reserved for a well-defined high-risk group of patients with evidence of ongoing ischemia, left ventricular dysfunction, heart failure, and perhaps some arrhythmias.

    Although coronary heart disease (CHD) requires a significant amount of self-care, there are no instruments available to measure self-care in this population. The purpose of this study was to test the psychometric properties of the Self-Care of Coronary Heart Disease Inventory (SC-CHDI). Using the Self-Care of Chronic Illness theory, we developed a 22-item measure of maintenance, management, and confidence appropriate for persons with stable CHD and tested it in a convenience sample of 392 adults (62% male, mean age 61.4 ± 9.6 years). Factorial validity was tested with confirmatory factor analysis. Convergent validity was tested with the Medical Outcomes Study MOS-SAS Specific Adherence Scale and the Decision Making Competency Inventory (DMCI). Cronbach alpha and factor determinacy scores (FDS) were calculated to assess reliability. Two multidimensional self-care scales were confirmed: self-care maintenance included "consultative behaviors" (e.g., taking medicines as prescribed) and "autonomous behaviors" (e.g., exercising 30 minute/day; FDS = .87). The multidimensional self-care management scale included "early recognition and response" (e.g., recognizing symptoms) and "delayed response" (e.g., taking an aspirin; FDS = .76). A unidimensional confidence factor captured confidence in each self-care process (α = .84). All the self-care dimensions were associated with treatment adherence as measured by the MOS-SAS. Only self-care maintenance and confidence were associated with decision-making (DCMI). These findings support the conceptual basis of self-care in patients with CHD as a process of maintenance that includes both consultative and autonomous behaviors, and management with symptom awareness and response. The SC-CHDI confidence scale is promising as a measure of self-efficacy, an important factor influencing self-care. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

    Obstructive sleep apnoea (OSA) favours the development of arterial hypertension independently of body-weight and may thus have an effect on coronary heart disease (CHD). This study was undertaken to determine the prevalence of OSA in patients with CHD. From among all patients in whom left heart catheterization with coronary angiography had provided the diagnosis of coronary heart disease 50 were randomly chosen (47 men, 3 women; mean age 61 +/- 6 years) for further investigations. During the night airway flow, heart rate, body position and arterial oxygen saturation were recorded. The patients also had to fill in a questionnaire concerning tiredness during the day and any snoring. Polysomnography was performed in all those whose apnoea index (AI) was > 10/h. 25 patients had an apnoea index of > 10/h. Eight of them also had increased tiredness during the day. The patients with an AI > 10/h were significantly older than those in whom it was 10/h registered an average AI of 17.0 +/- 10.9 per hour sleep; in seven patients it was > 20/h. The prevalence of obstructive sleep apnoea (OSA) is higher in patients with coronary heart disease (CHD) than in the healthy population. As OSA associated with a marked fall in nocturnal blood oxygen saturation and a rise in blood pressure may cause myocardial ischaemia, OSA should also always be considered when CHD is diagnosed.

    Acute coronary syndromes (ACS) are life-threatening medical emergencies that require urgent treatment, posing particular challenges for systems of health care in regional and remote parts of the world characterised by large distances and widely dispersed populations and healthcare facilities. Northern Australia is such an environment. The prevalence of cardiovascular risk factors, coronary artery disease and ACS (myocardial infarction and unstable angina) in northern Australia is amongst the highest in Australia. Despite the high burden of disease, appropriate healthcare services to address these important health challenges have been inadequate. The Australian Commission on Safety and Quality in Health Care has released a Clinical Care Standard for Acute Coronary Syndromes and the National Heart Foundation of Australia has developed an ACS Capabilities Framework, which together define minimum standards of care regardless of the patient's location. Strategies such as uniform state-wide ACS clinical pathways provide guidance on how evidence-based care can be provided in a range of geographical settings and to all populations, including Indigenous Australians. The continuing evolution of cardiac catheter laboratories in Townsville, Cairns, Mackay and Darwin has facilitated improved treatment for ACS in northern Australia, and has supported the development of region-wide, integrated, multidisciplinary pathways of care. Systems of care in ACS require consideration of the perspectives of the patient (from symptom onset to long-term secondary prevention of further events), the health system ('dissolving' traditional regional silos of care to enable a higher critical mass, greater cooperation, better communication and improved efficiency) and healthcare disciplines and services (including ambulance, retrieval, local health centres and local hospitals, tertiary centres, cardiac rehabilitation and general practice).

    Full Text Available Background. Healthcare is a challenging, yet so demanding sector that developing countries are paying more attention to recently. Statistics show that rural areas are expected to develop a high rate of heart diseases, which is a leading cause of sudden mortality, in the future. Thus, providing solutions that can assist rural people in detecting the cardiac risks early will be vital for uncovering and even preventing the long-term complications of cardiac diseases. Methodology. Mobile technology can be effectively utilized to limit the cardiac diseases’ prevalence in rural Middle East. This paper proposes a smart mobile solution for early risk detection of hard coronary heart diseases that uses the Framingham scoring model. Results. Smart HeartCare+ mobile app estimates accurately coronary heart diseases’ risk over 10 years based on clinical and nonclinical data and classifies the patient risk to low, moderate, or high. HeartCare+ also directs the patients to further treatment recommendations. Conclusion. This work attempts to investigate the effectiveness of the mobile technology in the early risk detection of coronary heart diseases. HeartCare+ app intensifies the communication channel between the lab workers and patients residing in rural areas and cardiologists and specialist residing in urban places.

    BACKGROUND: Subspecies of HDL contain apolipoprotein E (apoE) and/or apoCIII. Both proteins have properties that could affect HDL metabolism. The relation between HDL metabolism and risk of coronary heart disease (CHD) is not well understood. METHODS: Eighteen participants were given a bolus...... infusion of [D3]L-leucine to label endogenous proteins on HDL. HDL was separated into subspecies containing apoE and/or apoCIII and then into 4 sizes. Metabolic rates for apoA-I in HDL subspecies and sizes were determined by interactive modeling. The concentrations of apoE in HDL that contain or lack apo......CIII were measured in a prospective study in Denmark including 1,949 incident CHD cases during 9 years. RESULTS: HDL containing apoE but not apoCIII is disproportionately secreted into the circulation, actively expands while circulating, and is quickly cleared. These are key metabolic steps in reverse...

    To examine recent trends and social inequalities in age specific coronary heart disease mortality. Time trend analysis using joinpoint regression. Scotland, 1986-2006. Men and women aged 35 years and over. Age adjusted and age, sex, and deprivation specific coronary heart disease mortality. Persistent sixfold social differentials in coronary heart disease mortality were seen between the most deprived and the most affluent groups aged 35-44 years. These differentials diminished with increasing age but equalised only above 85 years. Between 1986 and 2006, overall, age adjusted coronary heart disease mortality decreased by 61% in men and by 56% in women. Among middle aged and older adults, mortality continued to decrease fairly steadily throughout the period. However, coronary heart disease mortality levelled from 1994 onwards among young men and women aged 35-44 years. Rates in men and women aged 45-54 showed similar flattening from about 2003. Rates in women aged 55-64 may also now be flattening. The flattening of coronary heart disease mortality in younger men and women was confined to the two most deprived fifths. Premature death from coronary heart disease remains a major contributor to social inequalities. Furthermore, the flattening of the decline in mortality for coronary heart disease among younger adults may represent an early warning sign. The observed trends were confined to the most deprived groups. Marked deterioration in medical management of coronary heart disease seems implausible. Unfavourable trends in the major risk factors for coronary heart disease (smoking and poor diet) thus provide the most likely explanation for these inequalities.

    Full Text Available Inflammation is an important factor in the pathogenesis of atherosclerosis, and several markers of inflammation have been associated with an increased risk of cardiovascular events. Physical activity may lower the risk of coronary heart disease(CHD by mitigating inflammation. The aim of the study was to investigate the effects of aerobic exercise training on systemic inflammatory response in patients with stabile coronary artery disease participating in a cardiovascular rehabilitation exercise program. Male (n=29 and female (n=23 patients with stable coronary heart disease were recruited for this study. All patients were divided into two groups: group with regular aerobic physical training during cardiovascular rehabilitation program phase II along 3 weeks in rehabilitation center and 3 weeks after that in home of patients and sedentary lifestyle group. There were no significant differences in gender distribution among analyzed groups. Student’s t test showed no significant difference in mean age, waist circumference (OS and waist/hip ratio (WHR. Degree of obesity was measured by BMI, and there was a significant improvement in BMI in patients who underwent the six-week physical training compared to control group (p<0.05.Physical training during 6 weeks did not show any effects on leukocyte count and ICAM-1 levels compared to control group. The exercise training induced reduction in plasma CRP levels by 23.72%, p<0.001, and reduction in plasma VCAM-1 levels by Moderate aerobic exercise training resulted in a significant reduction of inflammatory state by decreasing CRP and VCAM-1 levels without significant body mass and visceral obesity reduction. The obtained results indicate that regular physical activity is clinically attractive in primary and secondary prevention of coronary heart diseases.

    To evaluate how a comprehensive evidence-based clinical review by a multidisciplinary revascularization heart team on treatment decisions for revascularization in patients with complex coronary artery disease using SYNTAX scores combined with Society of Thoracic Surgeons-derived clinical variables can be additive to the utilization of Appropriate Use Criteria for coronary revascularization. Decision-making regarding the use of revascularization for coronary artery disease has come under major scrutiny due to inappropriate overuse of revascularization. There is little data in routine clinical practice evaluating how a structured, multidisciplinary heart team approach may be used in combination with the Appropriate Use Criteria for revascularization. From May 1, 2012 to January 1, 2015, multidisciplinary revascularization heart team meetings were convened to discuss evidence-based management of 301 patients with complex coronary artery disease. Heart team recommendations were adjudicated with the Appropriate Use Criteria for coronary revascularization for each clinical scenario using the Society for Cardiovascular Angiography and Interventions' Quality Improvement Toolkit (SCAI-QIT) Appropriate Use Criteria App. Concordance of the Heart Team to Appropriate Use Criteria had a 99.3% appropriate primary indication for coronary revascularization. Among patients who underwent percutaneous revascularization, 34.9% had an inappropriate or uncertain indication as recommended by the Heart Team. Patients with uncertain or inappropriate percutaneous coronary interventions had significantly higher SYNTAX score (27.3 ± 6.6; 28.5 ± 5.5; 19.2 ± 6; P coronary artery disease. A formal, multidisciplinary revascularization heart team can provide proper validation for clinical decisions and should be considered in combination with the Appropriate Use Criteria for coronary revascularization to formulate revascularization strategies for individuals in a patient

    Directory of Open Access Journals (Sweden)

    Meeshanthini V Dogan

    Full Text Available An improved method for detecting coronary heart disease (CHD could have substantial clinical impact. Building on the idea that systemic effects of CHD risk factors are a conglomeration of genetic and environmental factors, we use machine learning techniques and integrate genetic, epigenetic and phenotype data from the Framingham Heart Study to build and test a Random Forest classification model for symptomatic CHD. Our classifier was trained on n = 1,545 individuals and consisted of four DNA methylation sites, two SNPs, age and gender. The methylation sites and SNPs were selected during the training phase. The final trained model was then tested on n = 142 individuals. The test data comprised of individuals removed based on relatedness to those in the training dataset. This integrated classifier was capable of classifying symptomatic CHD status of those in the test set with an accuracy, sensitivity and specificity of 78%, 0.75 and 0.80, respectively. In contrast, a model using only conventional CHD risk factors as predictors had an accuracy and sensitivity of only 65% and 0.42, respectively, but with a specificity of 0.89 in the test set. Regression analyses of the methylation signatures illustrate our ability to map these signatures to known risk factors in CHD pathogenesis. These results demonstrate the capability of an integrated approach to effectively model symptomatic CHD status. These results also suggest that future studies of biomaterial collected from longitudinally informative cohorts that are specifically characterized for cardiac disease at follow-up could lead to the introduction of sensitive, readily employable integrated genetic-epigenetic algorithms for predicting onset of future symptomatic CHD.

    Background In Tunisia, Cardiovascular Diseases are the leading causes of death (30%), 70% of those are coronary heart disease (CHD) deaths and population studies have demonstrated that major risk factor levels are increasing. Objective To explain recent CHD trends in Tunisia between 1997 and 2009. Methods Data Sources: Published and unpublished data were identified by extensive searches, complemented with specifically designed surveys. Analysis Data were integrated and analyzed using the previously validated IMPACT CHD policy model. Data items included: (i)number of CHD patients in specific groups (including acute coronary syndromes, congestive heart failure and chronic angina)(ii) uptake of specific medical and surgical treatments, and(iii) population trends in major cardiovascular risk factors (smoking, total cholesterol, systolic blood pressure (SBP), body mass index (BMI), diabetes and physical inactivity). Results CHD mortality rates increased by 11.8% for men and 23.8% for women, resulting in 680 additional CHD deaths in 2009 compared with the 1997 baseline, after adjusting for population change. Almost all (98%) of this rise was explained by risk factor increases, though men and women differed. A large rise in total cholesterol level in men (0.73 mmol/L) generated 440 additional deaths. In women, a fall (−0.43 mmol/L), apparently avoided about 95 deaths. For SBP a rise in men (4 mmHg) generated 270 additional deaths. In women, a 2 mmHg fall avoided 65 deaths. BMI and diabetes increased substantially resulting respectively in 105 and 75 additional deaths. Increased treatment uptake prevented about 450 deaths in 2009. The most important contributions came from secondary prevention following Acute Myocardial Infarction (AMI) (95 fewer deaths), initial AMI treatments (90), antihypertensive medications (80) and unstable angina (75). Conclusions Recent trends in CHD mortality mainly reflected increases in major modifiable risk factors, notably SBP and

    To investigate this association between ABO blood groups and coronary heart disease (CHD) in the Chinese Guangxi Zhuang population. From August 2010 to April 2013, we performed a case-control study in a Chinese Zhuang population, which included 1 024 CHD cases and 1 024 age and gender-matched non-CHD controls. The ABO blood groups and biological variables were measured by standard laboratory procedures. The Gensini score was used to evaluate the severity of coronary artery stenosis. Compared to non-CHD control group, CHD group had higher levels of fasting blood glucose ((6.71 ± 6.72) mmol/L vs. (4.98 ± 1.55) mmol/L, P blood groups were associated with CHD risk in the Chinese Zhuang population. Compared with group O, the group B individuals had a higher risk of CHD (OR = 2.33, 95% CI 1.88-2.90, P group O subjects in the CHD group, and MACE at 1-year follow-up was similar between ABO blood groups of CHD individuals. ABO blood groups are associated with CHD risk in the Chinese Zhuang population.

  20. BAF200 is required for heart morphogenesis and coronary artery development.

    Full Text Available ATP-dependent SWI/SNF chromatin remodeling complexes utilize ATP hydrolysis to non-covalently change nucleosome-DNA interactions and are essential in stem cell development, organogenesis, and tumorigenesis. Biochemical studies show that SWI/SNF in mammalian cells can be divided into two subcomplexes BAF and PBAF based on the subunit composition. ARID2 or BAF200 has been defined as an intrinsic subunit of PBAF complex. However, the function of BAF200 in vivo is not clear. To dissect the possible role of BAF200 in regulating embryogenesis and organ development, we generated BAF200 mutant mice and found they were embryonic lethal. BAF200 mutant embryos exhibited multiple cardiac defects including thin myocardium, ventricular septum defect, common atrioventricular valve, and double outlet right ventricle around E14.5. Moreover, we also detected reduced intramyocardial coronary arteries in BAF200 mutants, suggesting that BAF200 is required for proper migration and differentiation of subepicardial venous cells into arterial endothelial cells. Our work revealed that PBAF complex plays a critical role in heart morphogenesis and coronary artery angiogenesis.

    Full Text Available Coronary heart disease (CHD, synonymously known as coronary artery disease (CAD is the most predominant among the cardiovascular diseases and ranked number one in prevalence among the developing countries. CHD is a multifactorial disease involving both genetic and environmental factors and is primarily caused due to a process of progressive damage of coronary arteries called atherosclerosis. We present here a comprehensive review of molecular genetic studies conducted so far on CAD. The information was gathered through the internet using appropriate search terms for CHD/CAD. We also compiled the relevant information from the following websites: http://www.bioguo.org/CADgene/and http://www.genome.gov. Besides several Mendelian forms of the CHD, ~300 more genes have been identified in different studies through candidate gene approach. Additionally 32 more loci have been identified through genome wide association studies that include 9p21.3 as the most replicated genetic locus across the globe. Nevertheless, overall, these studies have been characterized by a relative lack of consistency in the association pattern across the populations. A fair degree of ethnic variation in the nature of association of different genetic variants with the disease has also been apparent. Pleiotropic effects of genes, existence of subclinical phenotypes and genetic heterogeneity appear to have been the limiting factors for developing a genetic risk profile test for the disease. Given the high prevalence of this disease in India, the presence of environmental triggers and genetic variation, it would be prudent to conduct multi-ethnic large-scale studies in India, representing the subcontinent as a whole-there have been a very limited number of molecular genetic studies on Indian populations.

    Characterization of myocardial structural changes in heart failure with preserved ejection fraction (HFpEF) has been hindered by the limited availability of human cardiac tissue. Cardiac hypertrophy, coronary artery disease (CAD), coronary microvascular rarefaction, and myocardial fibrosis may contribute to HFpEF pathophysiology. We identified HFpEF patients (n=124) and age-appropriate control subjects (noncardiac death, no heart failure diagnosis; n=104) who underwent autopsy. Heart weight and CAD severity were obtained from the autopsy reports. With the use of whole-field digital microscopy and automated analysis algorithms in full-thickness left ventricular sections, microvascular density (MVD), myocardial fibrosis, and their relationship were quantified. Subjects with HFpEF had heavier hearts (median, 538 g; 169% of age-, sex-, and body size-expected heart weight versus 335 g; 112% in controls), more severe CAD (65% with ≥1 vessel with >50% diameter stenosis in HFpEF versus 13% in controls), more left ventricular fibrosis (median % area fibrosis, 9.6 versus 7.1) and lower MVD (median 961 versus 1316 vessels/mm(2)) than control (PHeart weight, fibrosis, and MVD were similar in HFpEF patients with CAD versus without CAD. In this study, patients with HFpEF had more cardiac hypertrophy, epicardial CAD, coronary microvascular rarefaction, and myocardial fibrosis than controls. Each of these findings may contribute to the left ventricular diastolic dysfunction and cardiac reserve function impairment characteristic of HFpEF. © 2014 American Heart Association, Inc.

    Objective: To evaluate the influence of heart rate and reconstruction window on image quality of multi-slice spiral CT coronary angiography. Methods: Retrospectively ECG-gated MSCT coronary angiography were performed in 80 healthy cases. Results: Four coronary (RCA, LM, LAD, LCX) segments were analyzed in each patient with regard to image quality. 82.1% (46/56) of the coronary segments were sufficient for analysis in patients with heart rate ≤60 bpm, 63.4% (104/164) with 61-70 bpm, 41.2%(28/68) with 71-80 bpm, and 31.2%(10/32) with>80 bpm, respectively. The left anterior descending artery, left circumflex artery, and the right coronary artery were best visualized when the reconstruction window was 60%-70%, 50%-60%, and 50%-70%, respectively. Conclusion: Image quality of MSCT coronary angiography is highly dependent on heart rate and reconstruction window

    Noncoronary forms of atherosclerosis (including transient ischemic attacks or stroke of carotid origin or >50% stenosis of the carotid artery) are associated with a 10-year vascular risk of >20% and are considered as a coronary heart disease (CHD) -risk equivalent from the standpoint of lipid management. The Stroke Prevention by Aggressive Reduction in Cholesterol Levels (SPARCL) trial included patients with stroke or transient ischemic attack and no known CHD regardless of the presence of carotid atherosclerosis. We evaluated the risk of developing clinically recognized CHD in SPARCL patients. A total of 4731 patients (mean age, 63 years) was randomized to 80 mg/day atorvastatin placebo. The rates of major coronary event, any CHD event, and any revascularization procedure were evaluated. After 4.9 years of follow-up, the risks of a major coronary event and of any CHD end point in the placebo group were 5.1% and 8.6%, respectively. The rate of outcome of stroke decreased over time, whereas the major coronary event rate was stable. Relative to those having a large vessel-related stroke at baseline, those having a transient ischemic attack, hemorrhagic stroke, small vessel stroke, or a stroke of unknown cause had similar absolute rates for a first major coronary event and for any CHD event; transient ischemic attack, small vessel, and unknown cause groups had lower absolute revascularization procedure rates. Major coronary event, any CHD event, and any revascularization procedure rates were similarly reduced in all baseline stroke subtypes in the atorvastatin arm compared with placebo with no heterogeneity between groups. CHD risk can be substantially reduced by atorvastatin therapy in patients with recent stroke or transient ischemic attack regardless of stroke subtype.

    Aims Our goal was to evaluate the association between antidepressant use and the risk of coronary heart disease (CHD) among subjects with no history of coronary heart disease. Methods A search of Medline, EMBASE, PsycINFO and the Cochrane Library was performed in January 2013. Two authors independently reviewed and selected eligible observational studies, based on predetermined selection criteria. Pooled relative risks (RRs) with confidence intervals (CIs) were calculated using random-effects or fixed-effects models. Results Sixteen observational studies (seven case–control studies and nine cohort studies) were included in the final analysis. There was no association between selective serotonin reuptake inhibitor use and the risk of CHD overall [odds ratio (OR), 0.93; 95% CI, 0.65–1.33] or in subgroup meta-analysis of case–control studies (OR, 0.91; 95% CI, 0.60–1.37) and cohort studies (RR, 0.96; 95% CI, 0.59–1.55). The use of tricyclic antidepressant was associated with an increased risk of CHD overall (OR, 1.51; 95% CI, 1.07–2.12), but it was observed only in case–control studies (OR, 1.56; 95% CI, 1.24–1.96) and low-quality studies (OR, 1.49; 95% CI, 1.20–1.85) in the subgroup meta-analyses. Conclusions This meta-analysis of observational studies in subjects with no history of CHD suggests that neither selective serotonin reuptake inhibitor nor tricyclic antidepressant use is associated with an increased risk of CHD.

    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. 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. 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. 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 heart rate was not associated with sudden death. © 2016 Canadian Medical

    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.

    Full Text Available Objective. The aim of this overview was to evaluate and summarize Cochrane reviews of traditional Chinese herbal products (TCHPs as the treatment for coronary heart disease (CHD. Methods. We searched the Cochrane Database that was concerned with the effectiveness of TCHPs for CHD. We also searched the Cochrane Central Register of Controlled Trials. Reviews and primary studies of TCHP as the treatment of any type of CHD were included. Data were extracted according to predefined inclusion criteria by two independent reviewers. Results. Six Cochrane reviews were included. They related to a wide range of TCHPs for different types of CHD. Four reviews were concerned with angina pectoris (unstable or stable, one review was concerned with heart failure, and for acute myocardial infarction. No reviews concluded that TCHPs were definitely effective for CHD because of the weak evidence. Eight primary studies were TCHPs from CHD. These studies also maybe result in bias, but better than before. Conclusion. Several Cochrane reviews of TCHPs for the treatment of different types of CHD have recently been published. None of these reviews got definite conclusion favoring the effectiveness of TCHPs due to the weak evidence. With the improved quality of the new registered RCTs. The potential role of TCHPs in treating CHD is anticipated to be detected.

    Trieu, Nelson; Eslick, Guy D

    2014-10-20

    Alopecia has been associated with an increased risk of coronary heart disease as well as the following risk factors for cardiovascular disease: hyperinsulinaemia, insulin resistance, metabolic syndrome, dyslipidaemia, and hypertension. We performed a meta-analysis to quantitatively determine the level of risk of coronary heart disease and risk factors in individuals with alopecia. A systematic literature search was conducted using several databases. We calculated pooled odds ratios and 95% confidence intervals using a random effects model. In total, 31 studies comprising 29,254 participants with alopecia were eligible for the meta-analysis and showed that alopecia is associated with an increased risk of coronary heart disease (OR 1.22, 95% CI: 1.07-1.39), hyperinsulinaemia (OR 1.97, 95% CI: 1.20-3.21), insulin resistance (OR 4.88, 95% CI: 2.05-11.64), and metabolic syndrome (OR 4.49, 95% CI: 2.36-8.53). Individuals with alopecia were also shown to be more likely compared to those without alopecia to have higher serum cholesterol levels (OR 1.60, 95% CI: 1.17-2.21), higher serum triglyceride levels (OR 2.07, 95% CI: 1.32-3.25), higher systolic blood pressures (OR 1.73, 95% CI: 1.29-2.33), and higher diastolic blood pressures (OR 1.59, 95% CI: 1.16-2.18). Alopecia is associated with an increased risk of coronary heart disease, and there appears to be a dose-response relationship with degree of baldness whereby the greater the severity of alopecia, the greater the risk of coronary heart disease. Alopecia is also associated with an increased risk of hypertension, hyperinsulinaemia, insulin resistance, metabolic syndrome, and having elevated serum total cholesterol and triglyceride levels.

    Aims Systematic reviews report an association between poorer oral health and an increased risk of coronary heart disease. This contentious relationship may not be causal but existing studies have been insufficiently well powered comprehensively to examine the role of confounding, particularly by cigarette smoking. Accordingly, we sought to examine the role of smoking in generating the relationship between oral health and coronary heart disease in life-long non-smokers. Methods and results In the Korean Cancer Prevention Study, 975,685 individuals (349,579 women) aged 30-95 years had an oral examination when tooth loss, a widely used indicator of oral health, was ascertained. Linkage to national mortality and hospital registers over 21 years of follow-up gave rise to 64,784 coronary heart disease events (19,502 in women). In the whole cohort, after statistical adjustment for age, there was a moderate, positive association between tooth loss and coronary heart disease in both men (hazard ratio for seven or more missing teeth vs. none; 95% confidence interval 1.08; 1.02, 1.14; P trend across tooth loss groups disease events), however, resulted in an elimination of this association in men (1.01; 0.85, 1.19); P trend 0.7506) but not women (1.08; 0.99, 1.18; P trend 0.0086). Conclusion In men in the present study, the relationship between poor oral health and coronary heart disease risk appeared to be explained by confounding by cigarette smoking so raising questions about a causal link.

    To assess the characteristics and determinants of heart rate turbulence (HRT) in individuals without any apparent heart disease and in patients with coronary artery disease (CAD). Heart rate turbulence parameters, turbulence onset (TO), and turbulence slope (TS) were calculated on 24 h electrocardiogram recordings in 209 individuals without any heart disease (group 1) and in 157 CAD patients (group 2). In group 1, only age independently predicted abnormal TO (≥0%) [odds ratio (OR), 1.05; PCoronary artery disease group, however, did not predict abnormal HRT parameters in multivariable analyses, both in the whole population and when comparing two subgroups matched for age and gender. Age and (for TS) LVEF, indeed, were the only independent predictors of abnormal HRT. Age is a major HRT determinant both in subjects without any apparent heart disease and in stable CAD patients. Hypertension and LVEF contribute independently to HRT in these two groups, respectively. Coronary artery disease group was not by itself associated with abnormal HRT parameters in multivariable analyses. Published on behalf of the European Society of Cardiology.

    Mediastinal radiation therapy (RT) for Hodgkin lymphoma (HL) is associated with late cardiotoxicity, but there are limited data to indicate which dosimetric parameters are most valuable for predicting this risk. This study investigated which whole heart dosimetric measurements provide the most information regarding late cardiotoxicity, and whether coronary artery dosimetry was more predictive of this outcome than whole heart dosimetry. A random sample of 125 HL patients treated with mediastinal RT was selected, and 3-dimensional cardiac dose-volume data were generated from historical plans using validated methods. Cardiac events were determined by linking patients to population-based datasets of inpatient and same-day hospitalizations and same-day procedures. Variables collected for the whole heart and 3 coronary arteries included the following: Dmean, Dmax, Dmin, dose homogeneity, V5, V10, V20, and V30. Multivariable competing risk regression models were generated for the whole heart and coronary arteries. There were 44 cardiac events documented, of which 70% were ischemic. The best multivariable model included the following covariates: whole heart Dmean (hazard ratio [HR] 1.09, P=.0083), dose homogeneity (HR 0.94, P=.0034), male sex (HR 2.31, P=.014), and age (HR 1.03, P=.0049). When any adverse cardiac event was the outcome, models using coronary artery variables did not perform better than models using whole heart variables. However, in a subanalysis of ischemic cardiac events only, the model using coronary artery variables was superior to the whole heart model and included the following covariates: age (HR 1.05, P<.001), volume of left anterior descending artery receiving 5 Gy (HR 0.98, P=.003), and volume of left circumflex artery receiving 20 Gy (HR 1.03, P<.001). In addition to higher mean heart dose, increasing inhomogeneity in cardiac dose was associated with a greater risk of late cardiac effects. When all types of cardiotoxicity were evaluated, the

    Ruptured sinus of Valsalva aneurysm is an unusual cause for congestive heart failure, and anomalous coronary arteries have rarely been found in association. A 47-year-old man developed sudden onset heart failure due to a ruptured noncoronary sinus of Valsalva fistula to the right atrium. Coronary angiography revealed an anomalous left coronary artery arising from the right coronary sinus, limiting percutaneous options for repair. We review the incidence, complications, and management of sinus of Valsalva aneurysms and anomalous left coronary arteries.

    Risk stratification in patients with stable ischemic heart disease is essential to guide treatment decisions. In this regard, whether coronary anatomy, physiology, or plaque morphology is the best determinant of prognosis (and driver an effective therapeutic risk reduction) remains one of the greatest ongoing debates in cardiology. In the present report, we review the evidence for each of these characteristics and explore potential algorithms that may enable a practical diagnostic and therapeutic strategy for the management of patients with stable ischemic heart disease. © 2016 American Heart Association, Inc.

    Atherosclerosis is a multifactor disease, in which dysfunction of the endothelium leads to the emergence of its adhesion molecules. to investigate the expression of the endothelial adhesion molecules PECAM (CD31), ICAM, and VCAM, as well as adherent endothelial T cells and monocytes. The material examined was en face pulmonary and coronary artery samples taken during autopsies (10 men), and en face specimens obtained from the coronary artery fragments taken from coronary heart disease patients during endarterectomy (37 men). This investigation used antibodies to the adhesion molecules ICAM-1, VCAM-1, and PECAM and those to CD3, CD4, CD8 T-cells and CD68 monocytes. The endothelial cells in the atherosclerotically intact coronary arteries had an elongated shape and were aligned along the blood flow. Those located above atheromas and fibroatheromas changed their shape from elongated to polygonal. Above the fatty streaks and atheromas, the reaction with antibodies to CD31 antigens became weaker at the edge of endothelial cells and disappeared in places. While the atherosclerotic process progressed, the reaction with the CD31 antigen at the edge of endothelial cells was similar in intensity to that on the surface of the endothelium. Adhesion of T cells and monocytes to the endothelium of coronary arteries increased as the atherosclerotic vascular process progressed. T cells and monocytes more often adhered to the endothelium at the sites where the endothelial cells contacted each other. Heterogeneity was found in the endothelial cells: their shape, the expression of adhesion molecules, and the adhesion of lymphocytes and monocytes to them changed during the progression of the atherosclerotic process.

    Coronary heart disease (CHD) is an important public health problem globally. Algorithms incorporating the assessment of clinical biomarkers together with several established traditional risk factors can help clinicians to predict CHD and support clinical decision making with respect to interventions. Decision tree (DT) is a data mining model for extracting hidden knowledge from large databases. We aimed to establish a predictive model for coronary heart disease using a decision tree algorithm. Here we used a dataset of 2346 individuals including 1159 healthy participants and 1187 participant who had undergone coronary angiography (405 participants with negative angiography and 782 participants with positive angiography). We entered 10 variables of a total 12 variables into the DT algorithm (including age, sex, FBG, TG, hs-CRP, TC, HDL, LDL, SBP and DBP). Our model could identify the associated risk factors of CHD with sensitivity, specificity, accuracy of 96%, 87%, 94% and respectively. Serum hs-CRP levels was at top of the tree in our model, following by FBG, gender and age. Our model appears to be an accurate, specific and sensitive model for identifying the presence of CHD, but will require validation in prospective studies. Copyright © 2017 Elsevier B.V.

    The role of periodontal disease remains a headline-generating topic. Periodontal disease, caused chiefly by bacteria, is characterized by inflammation, bacteremia, a strong immune response, and loss of connective tissue attachment and bone. It is speculated that a continuous long-term exposure to oral bacteremia and bacterial toxins induces immune responses that could contribute to coronary atherosclerosis and, in conjunction with other risk factors, lead to coronary heart disease and myocardial infarction. Periodontal disease might initiate pathological changes in blood vessel walls and act as a precursor of atherosclerosis in susceptible hosts. Many causal factors can play a role in heart diseases. Periodontal disease caused by pathogen bacteria as a low-grade inflammation could represent one of several possible causal factors of heart disease.

    The Scandinavian Simvastatin Survival Study (4S-Studie) has provided proof beyond any doubt that reduction of plasma cholesterol decreases mortality. The enormous rise of morbidity and mortality from cardiovascular disease in both gender calls for preventative measures as an urgent task. With a reduction of cardiac events by 30-40% and of mortality in the same order of magnitude, cholesterol lowering and increase in HDL-cholesterol are most effective measures for the treatment of coronary artery disease. However, not treatment of late stages of the disease, but primary prevention to reduce the incidence of coronary artery disease in this country should be the principle aim. Thus, the international guidelines for the treatment of lipid disorders considering the individual patient's risk profile have been revised.

    The case illustrates the possible link between coronary spasms, intraluminal thrombus formation, and widespread organized and layered thrombi in HTx patients. Furthermore, the case underlines the clinical value of OCT as a novel method for high-resolution vessel imaging in heart-transplanted (HTx......, and the left anterior descending coronary artery. The patient was stabilized after percutaneous coronary intervention. As a mural thrombus often goes undetected by coronary angiography, OCT may prove benefit in HTx patients with myocardial infarction or suspected coronary spasms....

    Full Text Available The aim of the research is a comparative investigation of Ivabradin vs Verapamil SR of antianginal/antiischemic activity, physical exertion tolerance and life quality of patients with coronary heart disease (CHD accompanied by bronchial obstructive diseases. Parallel groups of patients have been examined for a 16-week period. Ivabradin (average dose — 14mg/day or Verapamil SR (average dose — 443mg/day were administered to ischemic patients (n=84 with postinfarction cardiosclerosis, stable angina (class l-ll and painless myocardial ischemia. Concomitant bronchial obstructive deseases included controlled/partly controlled bronchial asthma or chronic obstructive pulmonary disease (stage II-III. Both medications have demonstrated the same antianginal/antiischemic activity and have improved physical exertion tolerance. Ivabradin was more effective for heart rate (HR aim level and 24-hour HR control. Ivabradin advantages were more expressed by changing of NYHA class (from class II to class I and increase of 6MWD. In conclusion Ivabradin has demonstrated its effectiveness in life quality improvement. Ivabradin and Verapamil SR did not cause complications in concomitant asthma/COPD and were good tolerated. It was determined that Ivabradin is a good Verapamil SR alternative for CHD treatment in case of bronchial obstructive concomitant diseases

    Higher social integration is associated with lower cardiovascular mortality; however, whether it is associated with incident coronary heart disease (CHD), especially in women, and whether associations differ by case fatality are unclear. This study sought to examine the associations between social integration and risk of incident CHD in a large female prospective cohort. Seventy-six thousand three hundred and sixty-two women in the Nurses' Health Study, free of CHD and stroke at baseline (1992), were followed until 2014. Social integration was assessed by a simplified Berkman-Syme Social Network Index every 4 years. End points included nonfatal myocardial infarction and fatal CHD. Two thousand three hundred and seventy-two incident CHD events occurred throughout follow-up. Adjusting for demographic, health/medical risk factors, and depressive symptoms, being socially integrated was significantly associated with lower CHD risk, particularly fatal CHD. The most socially integrated women had a hazard ratio of 0.55 (95% confidence interval, 0.41-0.73) of developing fatal CHD compared with those least socially integrated ( P for trend social integration and nonfatal myocardial infarction risk were largely explained by health-promoting behaviors, particularly through differences in cigarette smoking; however, the association with fatal CHD risk remained after accounting for these behaviors and, thus, may involve more direct biological mechanisms. Social integration is inversely associated with CHD incidence in women, but is largely explained by lifestyle/behavioral pathways. © 2017 American Heart Association, Inc.

    The main directions of state-of-the-art physical rehabilitation of patients with coronary heart disease (CHD) are early activation and development of new harmless programs of physical training (PT), improving indices of central hemodynamics and physical efficiency (PE) of patients. The purpose of the work is to study how bicycle training (BT) by the method of free choice of load (FCL) influence on central hemodynamics and PE of patients with various clinical forms of CHD at in-patient stage of physical rehabilitation. 185 patients with various forms of CHD at the age from 46 to 76 years (average age 68.4 +/- 1.6 years), 99 males and 86 females, were examined. Including of BT by the method of FCL in combined treatment of CHD patients was accompanied by significant improvement of heart pumping ability: increase in beat index, ejection fraction and PE in all clinical groups. Use only traditional therapy leaded to significant improvement only of ejection fraction, volume of performed work and threshold power in patients with paroxysmal atrial fibrillation and angina, but less expressive than with the use of BT. Absence of complication in our patients during treatment makes possible to recommend use of the method for CHD patients at in-patients stage of medical rehabilitation.

    Existing studies suggest that exercise-induced ischemia produces an increase in left ventricular end-diastolic volume; however, all of these studies have included patients with previous myocardial infarction. To test whether the end-diastolic volume response to exercise is related to the extent of myocardial scar, the results of gated radionuclide supine exercise tests performed on 130 subjects were reviewed. The patient group comprised 130 subjects were reviewed. The patient group comprised 130 men aged 35 to 65 years (mean +/- SD 52 +/- 5) with documented coronary heart disease. The extent of myocardial ischemia and scar formation was assessed by stress electrocardiography and thallium-201 scintigraphy. Patients were classified into three groups on the basis of left ventricular end-diastolic volume response at peak exercise: group 1 (n = 72) had an increase of end-diastolic volume greater than 10%, group 2 (n = 41) had a change in end-diastolic volume less than 10% and group 3 (n = 17) had a decrease in end-diastolic volume greater than 10% (n = 17). At rest there was no significant difference among groups in heart rate, systolic blood pressure, end-diastolic (EDVrest) or end-systolic volumes or ejection fraction (p greater than 0.05); however, at peak exercise the end-systolic volume response was significantly greater for group 1 (p less than 0.002)

    To examine whether we could predict myocardial ischemia when coronary artery calcification is detected by non-gated multidetector CT in patients with suspected ischemic heart disease. Eighty-three patients suspected of having ischemic heart disease (55 men, 28 women; age range 36-83 years; mean age 68 years) underwent multidetector CT and T1-201 single photon emission computed tomography. Prediction of myocardial ischemia by coronary arterial calcification detected on CT was evaluated by comparing the coronary artery territories that showed calcification with the area of myocardial ischemia determined by SPECT. The sensitivity, specificity, positive predictive value, and negative predictive value of multidetector CT for predicting myocardial ischemia were calculated. Coronary angiography was also examined and compared with multidetector CT. Risk factors, including hypertension, smoking, hyperlipidemia, diabetes, and family history, were compared for evidence of coronary artery calcification detected by multidetector CT and myocardial ischemia detected by thallium nuclear scans. For analysis by patients, the sensitivity, specificity, positive predictive value, and negative predictive value of coronary artery calcification for myocardial ischemia detection were 65, 63, 56, and 71%, respectively. Similarly, for analysis by coronary arterial territories, those values were 56, 77, 41 and 86%, respectively. Coronary stenosis on CAG was also related to the ischemia determined by SPECT and calcification on multidetector CT. Ischemia was better influenced by risk factors than was coronary arterial calcification. For analysis by coronary arterial territories, the specificity and negative predictive value of coronary arterial calcification seen by multidetector CT are relatively high.

    Objective: To examine the traditional risk factors and biochemical profile of patients with established CAD (coronary artery disease), and compare the trends of these in specified age groups of different populations as depicted in various studies. Methodology: All consecutive patients below 45 years of age, having classical history of Ischemic heart disease and also having definite ECG changes consistent with coronary artery disease were enrolled. These patients were admitted to CCU/Intermediate Coronary Care Unit of Pakistan Ordinance Factories (POF) Hospital Wah Cantonment from April 2007 to December 2011. Patients who had doubtful history as regards CHD and those having ECG changes not classically consistent with CAD were excluded. Information collected through Performa included history including family history and details of risk factors. Clinical examination was carried out and relevant investigations including the serial ECG changes were recorded. Blood samples were collected after an overnight fast of 14 hours and tests were done for total cholesterol and HDL cholesterol by using Pioneer-USA, linear chemical kits by cholesterol oxidase and enzymatic calometric method. Results: A total of 109 cases were included. Cigarette smoking (46%) Family history (43%), Hypertension (37%), Dyslipidemia (33%), Diabetes mellitus (18%) and above normal BMI (63.3%) are the most common risk factors in our patients. Increased abdominal girth has appeared to be an important risk factor and at occasions is documented to be independent of obesity. Casual dietary habits and sedentary life style are the other less important risk factors. The majority of risk factors were equally prevalent in males as well as females except smoking which was less prevalent in females. Conclusions: Our study shows that Family history, Smoking, Hypertension, increased BMI, increased Abdominal girth, Dyslipidemia and Diabetes Mellitus are the main risk factors. Considering the increasing incidence of

    This study determined the correlations of CXC ligand 16 (CXCL16) and tumor necrosis factor-α (TNF-α) levels with coronary atherosclerotic heart disease (CAHD) and screened for new clinical markers for the prognosis and treatment of the disease. Eighty patients with coronary heart disease and 50 healthy subjects were enrolled into a CAHD or healthy control group, respectively. Computed tomography (CT) coronary angiography and Gensini integral were used to classify plaques and evaluate patients with coronary heart disease. The serum levels of CXCL16 and TNF-α of subjects in each group were detected by enzyme-linked immunosorbent assays (ELISA), and the correlation between levels and clinical markers (such as blood pressure, glucose, lipid and heart rate) and the severity of disease were analyzed. Our results showed the serum levels of CXCL16 and TNF-α were significantly higher in the CAHD group than those in the CK group. The serum CXCL16 levels of the CAHD group patients with plaques were distinctly higher than those of the CADH group patients without plaques, but there were no significant difference in serum TNF-α levels between these two groups of patients. The level of CXCL16 had a significantly positive correlation with the severity of disease, but there was no significant correlation between TNF-α level and the severity of disease. Also, there was no significant correlation between the CXCL16 levels and blood pressure, blood glucose, heart rate, total cholesterol, triglyceride or high-density lipoprotein cholesterol, but there was a clear correlation with the low-density lipoprotein cholesterol. Finally no significant correlations were found between TNF-α levels and each of the clinical markers studied. Based on our findings, the levels of CXCL16 and TNF-α in the patients with coronary heart disease were abnormally increased and the level of CXCL16 correlated closely with the severity of disease. These markers seem to be reliable biological markers for

    A significant portion of coronary heart disease deaths occur out of the hospital, prior to access to life saving medical care. Improving the immediacy of care could have important impact on coronary mortality. The objective of this research is to identify factors associated with the occurrence of out-of-hospital coronary heart disease death as compared with in-hospital. Identification of these factors could lead to additional strategies for rapid treatment of coronary attack symptoms. A large national cohort study with individually identified characteristics was matched to the National Death Index to identify deaths by cause occurring in up to 11 years of follow-up. Approximately 60,000 deaths occurred in the cohort of approximately 700,000 participants aged 25 years or more. Location of death was defined as either in- or out-of-hospital. Among deaths classified as coronary heart disease (CHD), multivariate logistic models of the association between selected demographic and socioeconomic characteristics of individuals prior to death and place of death show that black persons are more likely to die out of hospital, as are persons who live alone or are unmarried, persons at the lowest end of the income distribution, and persons who live in rural areas vs. urban areas. The factors most strongly associated with a CHD death occurring out-of-hospital as compared with in-hospital are race (black persons are 1.23 times more likely to die out of hospital than white persons, net of demographic and socioeconomic differentials) and living status (persons who are not married are 1.60 times more likely to die out of hospital than persons who are married, net of demographic and socioeconomic characteristics). Attention should be paid to these groups to emphasize the need for rapid attention to the signs of a coronary attack so that rapid and potentially life saving intervention can be implemented.

    Full Text Available Accelerated sinus rhythm is an important side effect of inhaled salbutamol which is especially harmful in patients with chronic obstructive pulmonary disease (COPD and coronary heart disease (CHD. Cross-over, randomized, open label study design. 20 patients (18 males and two females with COPD stage II–IV and comorbide CHD NYHA class I–III were included. Spirometry with 400 mg salbutamol inhalation was performed at two consecutive days of the study. Patients in group I were prescribed 5 mg ivabradine per os 3 h before salbutamol inhalation solely on the first day of the study and patients of group II received 5 mg ivabradine only on the second day of the study. Salbutamol caused a significant increase of HR by 5.5 bpm (95% CI 0.8; 10.2, p < 0.03. After ivabradine ingestion salbutamol did not change HR significantly by −2.4 bpm (−7.0; 2.3, p = 0.33. The attenuation of HR elevation by ivabradine was significant, p < 0.01. Salbutamol alone increased FEV1 by 6.0% (2.7; 9.3, p < 0.01. This effect was not impaired by ivabradine (FEV1 increase by 7.7% (2.8; 12.6, p < 0.01 versus baseline, p = 0.5 versus no ivabradine. Ivabradine 5 mg per os prevents heart rate acceleration after inhalation of 400 mg salbutamol. Ivabradine has no impact on lung function in patients with moderate-to-very-severe COPD and CHD comorbidity.

    Although an inverse association of red blood cell cis-vaccenic acid and risk of myocardial infarction has been reported, it is unclear whether cis-vaccenic acid might lower the risk of heart failure (HF) with antecedent coronary heart disease (CHD). We sought to examine the relation of plasma cis-vaccenic acid with HF with antecedent CHD. This nested case-control study was based on 788 incident HF cases (of whom 258 cases had antecedent CHD) and 788 controls. Each control was selected using a risk set sampling technique at the time of the occurrence of the index case and matched on year of birth, age at blood collection, and race. Fatty acids were measured using gas chromatography and incident HF was self-reported on annual questionnaires and validation in a subsample using medical records. In a multivariable conditional logistic regression, the odds ratio (95% confidence interval) for HF with prior CHD were 1.0 (ref), 0.72 (0.33-1.57), 0.28 (0.12-0.67), and 0.23 (0.09-0.58) across consecutive quartiles of cis-vaccenic acid (p_trend 0.0004). Each standard deviation of cis-vaccenic acid was associated with a 41% lower risk of HF with antecedent CHD (95% CI: 17%-59%) in a multivariable adjusted model. Our data suggest that higher plasma levels of plasma cis-vaccenic acid may be associated with a lower risk of HF with antecedent CHD. Confirmation of these results in the general population including women and other ethnic groups is warranted. Copyright © 2013 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism.

    This study examined the association between job-related behavioral characteristics and the risk of coronary heart diseases (CHD) in Japanese male police officers. Compared to office clerks, police officers exhibited greater age-related increases of the prevalence of CHD risk factors, and a clustering number of CHD risk factors was significantly higher in the group of those over 45 yr of age. Among the police officers, coronary-prone behavior was more frequent than that seen in office clerks. The police officers with coronary-prone behavior tended to engage in shift work and to work overtime more; yet they were less likely to perceive job stress and to express the relevant physical and psychological symptoms than those without coronary-prone behavior. The subjects with such behavioral characteristics had a significantly greater number of CHD risk factors. In a multiple regression analysis, coronary-prone behavior together with age, social support, walking hours per day, and amount of alcohol consumption were selected as significant determinants of a cluster of CHD risk factors. These results suggest that coronary-prone behavior may contribute to the higher prevalence of CHD risk factors in police officers via leading the long working hours and the work-related unfavorable lifestyles, such as alcohol drinking and physical inactivity.

    Full Text Available Short telomere length independently predicts mortality in patients with coronary heart disease. Whether 5-year change in telomere length predicts subsequent mortality in patients with coronary heart disease has not been evaluated.In a prospective cohort study of 608 individuals with stable coronary artery disease, we measured leukocyte telomere length at baseline and after five years of follow-up. We divided the sample into tertiles of telomere change: shortened, maintained or lengthened. We used Cox survival models to evaluate 5-year change in telomere length as a predictor of mortality.During an average of 4.2 years follow-up, there were 149 deaths. Change in telomere length was inversely predictive of all-cause mortality. Using the continuous variable of telomere length change, each standard deviation (325 base pair greater increase in telomere length was associated with a 24% reduction in mortality (HR 0.76, 95% CI 0.61-0.94; p = 0.01, adjusted for age, sex, waist to hip ratio, exercise capacity, LV ejection fraction, serum creatinine, and year 5 telomere length. Mortality occurred in 39% (79/203 of patients who experienced telomere shortening, 22% (45/203 of patients whose telomere length was maintained, and 12% (25/202 of patients who experienced telomere lengthening (p<0.001. As compared with patients whose telomere length was maintained, those who experienced telomere lengthening were 56% less likely to die (HR 0.44, 95% CI, 0.23-0.87.In patients with coronary heart disease, an increase in leukocyte telomere length over 5 years is associated with decreased mortality.

    The association between breakfast intake and the risk of cardiovascular disease, including stroke, among Asian people remains unknown. We sought to prospectively investigate whether the omission of breakfast is related to increased risks of stroke and coronary heart disease in general Japanese populations. A total of 82,772 participants (38,676 men and 44,096 women) aged 45 to 74 years without histories of cardiovascular disease or cancer were followed up from 1995 to 2010. Participants were classified as having breakfast 0 to 2, 3 to 4, 5 to 6, or 7 times/wk. The hazard ratios of cardiovascular disease were estimated using Cox proportional hazards models. During the 1 050 030 person-years of follow-up, we documented a total of 4642 incident cases, 3772 strokes (1051 cerebral hemorrhages, 417 subarachnoid hemorrhages, and 2286 cerebral infarctions), and 870 coronary heart disease. Multivariable analysis showed that those consuming no breakfast per week compared with those consuming breakfast everyday had hazard ratios (95% confidence interval; P for trend) of 1.14 (1.01-1.27; 0.013) for total cardiovascular disease, 1.18 (1.04-1.34; 0.007) for total stroke, and 1.36 (1.10-1.70; 0.004) for cerebral hemorrhage. Similar results were observed even after exclusion of early cardiovascular events. No significant association between the frequency of breakfast intake and the risk of coronary heart disease was observed. The frequency of breakfast intake was inversely associated with the risk of stroke, especially cerebral hemorrhage in Japanese, suggesting that eating breakfast everyday may be beneficial for the prevention of stroke. © 2016 American Heart Association, Inc.

  12. Magnetic Resonance Imaging Measurement of Left Ventricular Blood Flow and Coronary Flow Reserve in Patients with Chronic Heart Failure due to Coronary Artery Disease

    Background: Coronary sinus flow reflects global cardiac perfusion and has been used for the assessment of myocardial flow reserve, which is reduced in chronic heart failure (CHF). Coronary flow reserve (CFR) can be measured by using phase-contrast (PC) velocity-encoded cine (VEC) magnetic resonance imaging (MRI). Purpose: To quantify and compare global left ventricular (LV) perfusion and CFR in patients with CHF and in a healthy control group by measuring coronary sinus flow with PC VEC MRI, and to correlate this with global LV perfusion, segmental first-pass perfusion, and viability in the same patients. Material and Methods: Cardiac MRI was performed in 20 patients with CHF of ischemic origin and in a control group of healthy subjects (n 11) at rest and after pharmacological stress induced by i.v. dipyridamole. The MRI protocol included cine MRI, VEC MRI, first-pass perfusion, and delayed contrast-enhanced MRI for viability. Global LV perfusion was quantified by measuring coronary sinus flow on VEC MRI at rest in all subjects. CFR was determined as the ratio of global LV perfusion before and after pharmacologic stress. Results: At rest, global LV perfusion was not significantly different in patients with CHF and the control group. After administration of dipyridamole, global LV perfusion and CFR were significantly lower in patients with CHF compared to the control group (P<0.001). An inverse correlation was observed between CFR and the number of infarcted and/or ischemic segments (P = 0.083, P = 0.037). Conclusion: A combined cardiac MRI protocol including function and perfusion techniques together with VEC MRI can be used to evaluate global LV perfusion and CFR in patients with CHF. Global LV perfusion and CFR measurements may have potential in the monitoring of CHF. Impaired CFR may contribute to progressive decline in LV function in patients with CHF

    To study and investigate branching patterns of the canine coronary arteries and collateral circulation by use of corrosion casting techniques. 31 hearts obtained from cadavers of clinically normal dogs of various ages and breeds and of either sex. 3-dimensional reproduction of coronary arteries was achieved by postmortem injection and perfusion with casting materials into the aortic sinus via the ascending aorta. Perfused hearts were macerated and carefully irrigated; the air-dried specimens were examined macroscopically and with a magnifying headset. Collateral arteries and inter- and intra-arterial anastomoses were successfully detected in 8 corrosion cast specimens. In total, 9 coronary collateral arteries and 3 interarterial anastomoses were found. Our finding of coronary collateral arteries in canine hearts is in agreement with recent findings in coronary flow study. On the basis of our results, vasodilation treatment to improve collateral vessel remodeling in dogs with myocardial dysfunction may be warranted.

    The adult practice for ECG-gated single-source 64-slice coronary CTA (CCTA) includes administering beta-blockers to reduce heart rate. There are limited data on this process in children. To evaluate the safety and efficacy of a drug regimen to decrease heart rate before performing CCTA in children. IV remifentanil and esmolol infusion were chosen to decrease heart rate in 41 children (mean age 6.5 years) while they were under general anesthesia (GA) for CCTA. Drug doses, changes in heart rate and procedural complications were recorded. CCTA image quality was graded on a scale of 1 to 5. The relationships between image quality and heart rate and image quality and age were evaluated. Patient effective radiation doses were calculated. Heart rates were lowered utilizing esmolol (4 children), remifentanil (2 children) or both (35 children); 26 children received nitroglycerin for coronary vasodilation. The mean decrease in heart rate was 26%. There were no major complications. The average image-quality score was 4.4. Higher heart rates were associated with worse image quality (r = 0.67, P < 0.0001). Older age was associated with better image quality (r = 0.66, P < 0.0001). Effective radiation doses were 0.7 to 7.0 mSv. Heart rate reduction for pediatric CCTA can be safely and effectively achieved while yielding high-quality images. (orig.)

    We studied 306 patients with chest pain (262 with coronary artery disease and 44 with no coronary artery disease) to determine which of 23 clinical, exercise, thallium, and angiographic variables best discriminate between patients with increased lung/heart ratios of thallium versus those with normal ratios. Normal lung/heart ratio values were defined using an additional 45 subjects with less than 1% probability of coronary artery disease. The number of diseased vessels was the best discriminator between patients with increased ratios versus those with normal ratios. Double product at peak exercise, number of segments with abnormal wall motion, patient gender, and duration of exercise were also significant discriminators. Using discriminant function analysis these variables could correctly identify 81% of cases with increased lung/heart ratios and 72% of cases with normal ratios. These results indicate that an increased lung/heart ratio of thallium reflects exercise-induced left ventricular dysfunction and affords a better understanding of why this thallium parameter is a powerful prognostic indicator in patients with chest pain

    Full Text Available An association between depression and coronary heart disease is now accepted but there has been little primary care research on this topic. The UPBEAT-UK studies are centred on a cohort of primary patients with coronary heart disease assessed every six months for up to four years. The aim of this research was to determine the prevalence and associations of depression in this cohort at baseline.Participants with coronary heart disease were recruited from general practice registers and assessed for cardiac symptoms, depression, quality of life and social problems.803 people participated. 42% had a documented history of myocardial infarction, 54% a diagnosis of ischaemic heart disease or angina. 44% still experienced chest pain. 7% had an ICD-10 defined depressive disorder. Factors independently associated with this diagnosis were problems living alone (OR 5.49, 95% CI 2.11-13.30, problems carrying out usual activities (OR 3.71, 95% CI 1.93-7.14, experiencing chest pain (OR 3.27, 95% CI 1.58-6.76, other pains or discomfort (OR 3.39, 95% CI 1.42-8.10, younger age (OR 0.95 per year 95% CI 0.92-0.98.Problems living alone, chest pain and disability are important predictors of depression in this population.

    Full Text Available Due to the paucity of direct evidence, we aimed to evaluate whether the association between postload plasma glucose levels (ppGlucose and long-term risk of mortality from coronary heart disease was independent of or attributable to genes and common environment.From the prospective National Heart, Lung, and Blood Institute (NHLBI Twin Study, we included 903 middle-aged male twins, who were nondiabetic, free of coronary heart disease at baseline (1969-1973, and followed for up to 38 years for coronary heart, cardiovascular, and all-cause mortality. Frailty survival models were used to estimate hazard ratio (HR for various associations: overall (equivalent to singleton population association, within-pair (controlling for genes and environment common to co-twins, and between-pair association (reflecting influences of common factors. Overall associations were statistically significant for coronary heart and cardiovascular but not all-cause deaths after controlling for known risk factors. The associations were not statistically significant in within-pair analyses. The within-pair association was not statistically different by zygosity for specific and all-cause death risk. After the full adjustment for known risk factors, HR (95% confidence interval for within-pair association was 1.07 (0.90, 1.28, 1.06 (0.94, 1.19, and 0.99 (0.94, 1.05 for coronary heart, cardiovascular, and all-cause mortality, respectively. The fully adjusted between-pair associations were statistically significant for specific and all-cause death risk: a 50 mg/dL increase in the mean value of ppGlucose for a twin pair was associated with a raised death risk [HR (95% confidence interval 1.15 (1.02, 1.30, 1.10 (1.02, 1.20, and 1.05 (1.01, 1.09 for coronary heart, cardiovascular, and all-cause mortality, respectively].

    Objective: To evaluate the feasibility of dual-source computed tomography (DSCT) coronary angiography in a population with premature heart-beats. Methods: Seventy patients with suspected coronary artery disease and premature heart-beats were routinely imaged on a DSCT scanner (Somatom Definition, Siemens AG, Germany). The images were reconstmcted before and after ECG editing. Two readers independently assessed image quality of all coronary segments using a four-point grading scale from excellent (1) to non-assessable (4). The results of the two groups were compared with a paired t-test, and a P value of less than 0.05 was considered significant. Results: The mean heart rate during examination ranged from 49 to 111 bpm[ mean(70.7±12.4) bpm]. Twenty-eight of 70 patients with relatively small variability of the heart rate [(41.0±18.4) bpm] got diagnostic image quality without ECG editing. In other 42 patients with larger variability of the heart rate [(71.4±28.7) bpm], the mean image quality scores were 2.09±1.27 and 1.50±0.79 before and after ECG editing, there was a significant difference (t= 13.764, P 2 =121.846, P<0.01). Finally, the diagnostic image accounted 98.0% (1014/1035) in all segments of 70 patients. Conclusion: DSCT can provide diagnostic images for patients with premature heart-beats. The image quality in patients with larger variability of the heart rate can be significantly improved through ECG editing. (authors)

    Full Text Available Objective: to study the diagnostic value of placental growth factor (PlGF in patients with coronary heart disease (CHD. Subjects and methods. 151 patients (75 men and 76 women; mean age 58.9 ± 12.3 years, including 66 patients with exercise-induced stable angina, 32 with unstable angina, 32 with myocardial infarction, and 21 with no clinical signs of CHD, were followed up. Blood PlGF levels were measured in all the examinees; C-reactive protein (CRP concentrations were also determined using a high-sensitivity method in the patients with CHD.Results. In the patients with acute coronary syndrome (ACS, the levels of PlGF were significantly higher than in those with exercise-induced stable angina and in healthy individuals (17.3 ± 11.4 versus 11.2 ± 7.3 and 8.8 ± 6.7 pg/ml; p < 0.001. Estimation of the diagnostic value of the determination of PlGF levels in the diagnosis of ACS in troponin-negative examinees revealed that the area under the ROC curve (AUC was 0.76. The quality of a diagnostic model using CRP was inferior to that with PlGF (n = 45; AUC for PlGF = 0.79; that for CRP = 0.65.Conclusion. The elevated level of PlGF may be considered as a diagnostic marker for ACS, including in the absence of the higher levels of cardiac troponins.

    National guidelines recommend use of high-intensity statins after hospitalization for coronary heart disease (CHD) events. This study sought to estimate the proportion of Medicare beneficiaries filling prescriptions for high-intensity statins after hospital discharge for a CHD event and to analyze whether statin intensity before hospitalization is associated with statin intensity after discharge. We conducted a retrospective cohort study using a 5% random sample of Medicare beneficiaries between 65 and 74 years old. Beneficiaries were included in the analysis if they filled a statin prescription after a CHD event (myocardial infarction or coronary revascularization) in 2007, 2008, or 2009. High-intensity statins included atorvastatin 40 to 80 mg, rosuvastatin 20 to 40 mg, and simvastatin 80 mg. Among 8,762 Medicare beneficiaries filling a statin prescription after a CHD event, 27% of first post-discharge fills were for a high-intensity statin. The percent filling a high-intensity statin post-discharge was 23.1%, 9.4%, and 80.7%, for beneficiaries not taking statins pre-hospitalization, taking low/moderate-intensity statins, and taking high-intensity statins before their CHD event, respectively. Compared with beneficiaries not on statin therapy pre-hospitalization, multivariable adjusted risk ratios for filling a high-intensity statin were 4.01 (3.58-4.49) and 0.45 (0.40-0.52) for participants taking high-intensity and low/moderate-intensity statins before their CHD event, respectively. Only 11.5% of beneficiaries whose first post-discharge statin fill was for a low/moderate-intensity statin filled a high-intensity statin within 365 days of discharge. The majority of Medicare beneficiaries do not fill high-intensity statins after hospitalization for CHD. Copyright © 2015 American College of Cardiology Foundation. Published by Elsevier Inc.

    Whether catheterization of the right heart should be performed routinely in all patients undergoing coronary angiography for assessment of coronary artery disease is controversial. To objectively assess the utility of routine right heart catheterization, hemodynamic data from 2,178 patients studied for angina having no signs, symptoms, or history of congestive heart failure were analyzed retrospectively. The salient results are as follows: 0.9% patients had unsuspected mitral valve gradients greater than or equal to 5 mm Hg; 0.4% had occult left-to-right shunts; 1% had pulmonary hypertension (pulmonary artery systolic pressure greater than or equal to 40 mm Hg) not attributable to an elevated mean pulmonary capillary wedge pressure (PCWP); 4.8% had PCWP greater than or equal to 18 mm Hg; 6% had cardiac indexes less than or equal to 2.0 L/min/m2, suggesting subclinical left ventricular failure. Overall, 14.5% of patients had at least one abnormal right-sided hemodynamic variable revealed by right heart catheterization. The frequency of abnormalities increased with increasing Canadian Cardiovascular Society grade of angina. Ten percent of grade 1, 14% of grade 2, 15% of grade 3, and 19% of patient 4 patients had at least one abnormality (phi 2 test, p less than or equal to 0.005). It is concluded that the right heart catheterization adds an important dimension to the diagnosis and treatment of patients undergoing coronary angiography for assessment of coronary artery disease and might significantly influence subsequent patient management.

    Endothelial dysfunction and inflammatory reaction at the site of damage plays a key role in the formation of neointimal hyperplasia, and in the progression of atherosclerosis. The initiating role in these processes is assigned to adhesion molecules. We studied the dynamics of the level of adhesion molecules soluble intercellular adhesion molecule-1 (sICAM-1), soluble vascular adhesion molecule-1 (sVCAM-1), soluble form of the molecule platelet adhesion and endothelial type-1 (sPECAM-1), sL-, sP-, sE-selectins during double filtration plasmapheresis (DFPP) with use of plasma fractionators (PF) Cascadeflo EC-50W and EC-40W (Asahi Kasei Medical Co., Japan) in patients with stable coronary heart disease and hyperlipidemia-(a) in the early post-implantation period after coronary stenting. DFPP reduces the level of plasma adhesion molecules. When using PF Cascadeflo EC-40W, a more pronounced decrease occurs. The rejection coefficient (RC) of adhesion molecules has been identified for these PF. These RCs reflect the immediate removal efficiency of adhesion molecules in the perfusion of plasma through PF. The removal effectiveness of adhesion molecules when using PF Cascadeflo EC-40W is higher than when using the PF Cascadeflo EC-50W (sICAM-1 - 2.5 times, sVCAM-1 - 2.2 times, sPECAM-1.6 times, sL-selectin - 5 times, sP-selectin - 2.8 times, sE - selectin - 3 times). Reducing adhesion molecule levels when using DFPP may play an important role in correcting of endothelial dysfunction in response to damage to the arterial wall in percutaneous coronary intervention (PCI) during the early post-implantation period after coronary stenting. DFPP is a promising approach to prevent in-stent restenosis (ISR). Copyright © 2017 Elsevier B.V. All rights reserved.

    The beginnings of coronary artery bypass graft in Latin America could be set in the year 1971. Since then, improvements in technique and greater experience have resulted in a rapid increase in the rate of interventions performed in the region. Searches through PubMed and Literatura Latinoamericana y del Caribe en Ciencias de la Salud, as well as personal communications from specialists from Latin America, have been the source of information. Articles were selected by their content related to the theme, and the authors' nationality and information is mainly from Latin America. Demographic information of the population of Latin America denotes higher age averages, and this implies an increase in the severity of comorbidities in patients who undergo surgery. Longer life expectancy and improvements in medical therapy have implied that patients survive a first intervention beyond the expected time a bypass persists patent. Wall vessel properties of arterial conduits, plus a better anastomotic technique, seem to be the current solution to worsening in the coronary health of patients who undergo revascularization surgery in Latin America. Despite scarce economic investment in medical sciences, many academic groups contribute to the exploration of therapeutic pharmacological combinations and inclusively apply genetic strategies.

    Variation exists in the resource categories included in economic evaluations, and National Institute for Health and Care Excellence (NICE) guidance suggests the inclusion only of costs related to the index condition or intervention. However, there is a growing consensus that all healthcare costs should be included in economic evaluations for Health Technology Assessments (HTAs), particularly those related to extended years of life. We aimed to quantify the impact of a range of cost categories on the adoption decision about a hypothetical intervention, and uncertainty around that decision, for stable coronary artery disease (SCAD) based on a dataset comprising 94,966 patients. Three costing scenarios were considered: coronary heart disease (CHD) costs only, cardiovascular disease (CVD) costs and all costs. The first two illustrate different interpretations of what might be regarded as related costs. Employing a 20-year time horizon, the highest mean expected incremental cost was when all costs were included (£2468) and the lowest when CVD costs only were included (£2377). The probability of the treatment being cost effective, estimating health opportunity costs using a ratio of £30,000 per quality-adjusted life-year (QALY), was different for each of the CHD (70%) costs, CVD costs (73%) and all costs (56%) scenarios. The results concern a hypothetical intervention and are illustrative only, as such they cannot necessarily be generalised to all interventions and diseases. Cost categories included in an economic evaluation of SCAD impact on estimates of both cost effectiveness and decision uncertainty. With an aging and co-morbid population, the inclusion of all healthcare costs may have important ramifications for the selection of healthcare provision on economic grounds.

    Although the importance of smoking as a risk factor for coronary heart disease is beyond doubt, the speed and magnitude of risk reduction when a smoker with coronary heart disease quits are still subjects of debate. To estimate the magnitude of risk reduction when a patient with CHD stops smoking. We searched the Cochrane Register of Controlled Trials (CENTRAL) , MEDLINE, EMBASE, Science Citation Index, CINAHL, PsychLit, Dissertation Abstracts, BIDS ISI Index to Scientific and Technical Proceedings, UK National Research Register from the start of each database. Sixty-one large international cohort studies of cardiovascular disease were identified, and contact made with authors to search for any unpublished results. The search was supplemented by cross-checking references and contact with various experts. Date of last search was April 2003. Any prospective cohort studies of patients with a diagnosis of CHD, which include all-cause mortality as an outcome measure. Smoking status must be measured on at least two occasions to ascertain which smokers have quit, and followed-up for at least two years. Eligibility and trial quality were assessed independently by two reviewers. Twenty studies were included. There was a 36% reduction in crude relative risk (RR) of mortality for those who quit smoking compared with those who continued to smoke (RR 0.64, 95% confidence interval (CI) 0.58 to 0.71). There was also a reduction in non-fatal myocardial infarctions (crude RR 0.68, 95% CI 0.57 to 0.82). Many studies did not adequately address quality issues, such as control of confounding, and misclassification of smoking status. However, there was little difference in the results for the six 'higher quality' studies, and little heterogeneity between these studies. This review was not able to assess how quickly the risk of mortality was reduced. Quitting smoking is associated with a substantial reduction in risk of all-cause mortality among patients with CHD. The pooled crude RR was

    The subjects of the study were 30 patients with coronary heart disease (19--with stable, and 11--with instable angina), and 15 practically healthy individuals. The study included measurement of the levels of homocysteine (HC), total cholesterol, cholesterol of low-density lipoproteins, cholesterol of high-density lipoproteins, and lipidperoxidation (LP) products (TBA-reactive products), as well as coagulo-fibrinolytic parameters. The study revealed that patients with instable angina had significantly higher levels of HC and TBA-reactive products compared to those with stable angina and healthy controls. HC level correlated with LP processes in CHD patients (r = 0.55). Methionine loading allowed revealing latent hyperhomocysteinemia.

    In secondary cardiovascular prevention, discontinuation of acetylsalicylic acid (ASA) is associated with an increased risk of cardiovascular events. This study assessed the impact of ASA reinitiation on the risk of myocardial infarction and coronary heart disease death. Patients prescribed ASA for secondary cardiovascular prevention and who had had a period of ASA discontinuation of ≥90 days in 2000-2007 were identified from The Health Improvement Network (N = 10,453). Incidence of myocardial infarction/coronary heart disease death was calculated. Survival analyses using adjusted Cox proportional hazard models were performed to calculate hazard ratios and 95% confidence intervals for the risk of myocardial infarction/coronary heart disease death associated with ASA use patterns after the initial period of discontinuation. Individuals who were prescribed ASA during follow-up were considered reinitiators. The incidence of myocardial infarction/coronary heart disease death was 8.90 cases per 1000 person-years. Risk of myocardial infarction/coronary heart disease death was similar for current ASA users, who had been continuously exposed since reinitiation, and patients who had not reinitiated ASA (hazard ratio 1.27, 95% confidence interval 0.93-1.73). Among reinitiators, an additional period of ASA discontinuation was associated with increased risk of myocardial infarction/coronary heart disease death compared with no reinitiation (current users: hazard ratio 1.46, 95% confidence interval 1.13-1.90; noncurrent users: hazard ratio 1.70, 95% confidence interval 1.31-2.21). ASA reinitiation was not associated with a decreased risk of myocardial infarction/coronary heart disease death. This may be explained by confounding by indication/comorbidity, whereby higher-risk patients are more likely to reinitiate therapy. An additional period of ASA discontinuation among reinitiators was associated with an increased risk of myocardial infarction/coronary heart disease death

    Severe aortic stenosis (AS) can manifest as exertional angina even in the presence of unobstructed coronary arteries. The authors describe coronary physiological changes during exercise and hyperemia in the healthy heart and in patients with severe AS. Simultaneous intracoronary pressure and flow velocity recordings were made in unobstructed coronary arteries of 22 patients with severe AS (mean effective orifice area 0.7 cm(2)) and 38 controls, at rest, during supine bicycle exercise, and during hyperemia. Stress echocardiography was performed to estimate myocardial work. Wave intensity analysis was used to quantify waves that accelerate and decelerate coronary blood flow (CBF). Despite a greater myocardial workload in AS patients compared with controls at rest (12,721 vs. 9,707 mm Hg/min(-1); p = 0.003) and during exercise (27,467 vs. 20,841 mm Hg/min(-1); p = 0.02), CBF was similar in both groups. Hyperemic CBF was less in AS compared with controls (2,170 vs. 2,716 cm/min(-1); p = 0.05). Diastolic time fraction was greater in AS compared with controls, but minimum microvascular resistance was similar. With exercise and hyperemia, efficiency of perfusion improved in the healthy heart, demonstrated by an increase in the relative contribution of accelerating waves. By contrast, in AS, perfusion efficiency decreased due to augmentation of early systolic deceleration and an attenuated rise in systolic acceleration waves. Invasive coronary physiological evaluation can be safely performed during exercise and hyperemia in patients with severe aortic stenosis. Ischemia in AS is not related to microvascular disease; rather, it is driven by abnormal cardiac-coronary coupling. Copyright © 2016 American College of Cardiology Foundation.

    The effect of body mass index (BMI) on coronary heart disease (CHD) risk is attenuated when mediators of this risk (such as diabetes, hypertension and hyperlipidaemia) are accounted for. However, there is now evidence of a differential effect of risk factors on fatal and non-fatal CHD events, with markers of inflammation more strongly associated with fatal than non-fatal events. To describe the association with BMI separately for both fatal and non-fatal CHD risk after accounting for classical risk factors and to assess any independent effects of obesity on CHD risk. In the West of Scotland Coronary Prevention Study BMI in 6082 men (mean age 55 years) with hypercholesterolaemia, but no history of diabetes or CVD, was related to the risk of fatal and non-fatal CHD events. After excluding participants with any event in the first 2 years, 1027 non-fatal and 214 fatal CHD events occurred during 14.7 years of follow-up. A minimally adjusted model (age, sex, statin treatment) and a maximally adjusted model (including known CVD risk factors and deprivation) were compared, with BMI 25-27.4 kg/m² as referent. The risk of non-fatal events was similar across all BMI categories in both models. The risk of fatal CHD events was increased in men with BMI 30.0-39.9 kg/m² in both the minimally adjusted model (HR = 1.75 (95% CI 1.12 to 2.74)) and the maximally adjusted model (HR = 1.60 (95% CI 1.02 to 2.53)). These hypothesis generating data suggest that obesity is associated with fatal, but not non-fatal, CHD after accounting for known cardiovascular risk factors and deprivation. Clinical trial registration WOSCOPS was carried out and completed before the requirement for clinical trial registration.

  20. Heart rate and use of beta-blockers in stable outpatients with coronary artery disease.

    Ph Gabriel Steg

    Full Text Available BACKGROUND: Heart rate (HR is an emerging risk factor in coronary artery disease (CAD. However, there is little contemporary data regarding HR and the use of HR-lowering medications, particularly beta-blockers, among patients with stable CAD in routine clinical practice. The goal of the present analysis was to describe HR in such patients, overall and in relation to beta-blocker use, and to describe the determinants of HR. METHODS AND FINDINGS: CLARIFY is an international, prospective, observational, longitudinal registry of outpatients with stable CAD, defined as prior myocardial infarction or revascularization procedure, evidence of coronary stenosis of >50%, or chest pain associated with proven myocardial ischemia. A total of 33,438 patients from 45 countries in Europe, the Americas, Africa, Middle East, and Asia/Pacific were enrolled between November 2009 and July 2010. Most of the 33,177 patients included in this analysis were men (77.5%. Mean (SD age was 64.2 (10.5 years, HR by pulse was 68.3 (10.6 bpm, and by electrocardiogram was 67.2 (11.4 bpm. Overall, 44.0% had HR ≥ 70 bpm. Beta-blockers were used in 75.1% of patients and another 14.4% had intolerance or contraindications to beta-blocker therapy. Among 24,910 patients on beta-blockers, 41.1% had HR ≥ 70 bpm. HR ≥ 70 bpm was independently associated with higher prevalence and severity of angina, more frequent evidence of myocardial ischemia, and lack of use of HR-lowering agents. CONCLUSIONS: Despite a high rate of use of beta-blockers, stable CAD patients often have resting HR ≥ 70 bpm, which was associated with an overall worse health status, more frequent angina and ischemia. Further HR lowering is possible in many patients with CAD. Whether it will improve symptoms and outcomes is being tested.

    Premature coronary heart disease (CHD) significantly affects morbidity and mortality in systemic lupus erythematosus (SLE). Several studies have detected factors influencing the atherosclerotic process, as well as methods to quantify the atherosclerotic burden in subclinical stages. The aim of this systematic review was to identify the minimum investigations to optimally monitor CHD risk in SLE. English-restricted literature review was performed using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines through Ovid Medline, Embase, and Cochrane Central databases, from inception until May 2014 (Medline until October 2014). Specific search terms included, among others, "SLE," "atherosclerosis," "CHD," "myocardial ischemia," "acute coronary syndrome," "myocardial infarction," and "angina pectoris." We identified 101 eligible articles, 23 with cardiovascular events (CVE) as endpoints and 78 with measures of subclinical atherosclerosis. The Newcastle-Ottawa scale was used for quality assessment. Certain traditional and disease-specific factors were identified as independent predictors for CHD. Among the former were age (particularly postmenopausal state), male sex, arterial hypertension, dyslipidemia, and smoking. Disease activity and duration, cumulative damage, antiphospholipid antibodies, high sensitivity C-reactive protein, and renal disease were the most consistent disease-related factors. Corticosteroids were linked to increased CHD risk whereas antimalarials were protective. Concerning imaging techniques, carotid ultrasonography (intima-media thickness and plaque) was shown to independently predict CVE. Premature CHD in SLE is multifactorial; modifiable variables should be monitored at frequent intervals to ensure prompt management. Disease-specific factors also affect the atherogenic process and should be evaluated regularly. Carotid ultrasonography may hold promise in predicting CVE in selected high-risk patients.

    Full Text Available Heart disease is the first killer of women in the modern era, regardless of age, race and of ethnicity, although its prevalence rises after menopause. Modern women have professional and housewife responsibilities, consume excess of fat and carbohydrates, smoke, do not exercise regularly and do not have enough time to rest. This situation leads to overweight, dyslipidemia, arterial hypertension, impaired glucose tolerance and diabetes. Women do not often participate in preventive studies and still undergo less intensive and invasive evaluation and treatment for chest pain when compared to men. However, the rate of coronary death is twice higher in women than in men after myocardial infarction and revascularization procedures. The objective of this review is to analyze the main gender differences regarding symptoms, diagnosis, management and prognosis of coronary heart disease and to discuss the influence of hormonal replacement therapy in the prevention of cardiovascular disease in postmenopausal women.

    This study was performed to assess perceived social support and psychosocial adjustment in patients with coronary heart disease. Participants were 250 patients referred to the cardiology outpatient clinic of a university hospital in Ankara, Turkey, between December 2013 and March 2014. Data were collected using a participant information form, the Multidimensional Scale of Perceived Social Support, and the Psychosocial Adjustment to Illness Scale-Self-Report. Data were analysed using frequencies, percentages, mean scores, and Pearson's correlation coefficient. Patients' mean perceived social support scores were relatively low and patients' mean scores for psychosocial adjustment considered to be poor. Subgroups in the psychosocial adjustment and social support scales were significantly associated. This study's results indicate that patients' social support is linked to their psychosocial adjustment to coronary heart disease. As psychosocial adjustment is inhibited in patients who lack sufficient social support, sources of social support of patients should be identified and facilitated. © 2017 John Wiley & Sons Australia, Ltd.

    Objective: To explore the changes and clinical significance of serum insulinlike growth factor II (IGF II) levels in coronary heart disease (CHD) patients. Methods: The serum IGF II levels were determined by radioimmunoassay in 68 patients with coronary heart disease (CHD) and 30 controls with only mild non-cardiac diseases. Results: Compared with the controls, the serum IGF II level in CHD patients were increased significantly (0.66 ± 0.13 μg/L vs 0.51 ± 0.11 μg/L; t = 5.506, p 0.05). Level in patients dies in hospital (n = 9) were much higher than those in patients recovered (n = 59) (t = 2.402, p < 0.05). Conclusion: Serum IGF II levels seems to be related to the seriousness of CHD; the actual mechanism remains to be defined

    Aim: To assess the ability of coronary angiography performed using dual-source computed tomography (DSCT) to evaluate coronary artery disease (CAD) in a population with unselected heart rates and extensive coronary calcification. Materials and methods: Forty-four patients at intermediate to high risk for CAD underwent both DSCT coronary angiography and invasive coronary angiography (ICA) within 30 days. No beta blockers were administered prior to imaging. Image quality and quantitatively stenosis of all coronary segments with a diameter ≥1.5 mm were accessed. Patients were stratified according to mean heart rate (<70 versus ≥70 bpm) and heart rate variability (<10 versus ≥10 bpm). DSCT detection of coronary stenosis by segment, vessel, and patient characteristics were compared to the reference standard of ICA. Results: Diagnostic accuracy for all patients was high regarding sensitivity (97%), positive predictive value (PPV, 84.2%), and negative predictive value (NPV, 83.3%) but low regarding specificity (45.5%) with a moderate interobserver agreement (Kappa = 0.50). The accuracy for vessel-based diagnosis was high regarding sensitivity (96.6%), specificity (80.8%), PPV (80.3%), and NPV (96.7%). The segment-based diagnostic results revealed a moderate interobserver agreement for image quality and sensitivity, specificity, PPV and NPV for all segments of 66.9, 97.8, 90.8, and 89.9%, respectively. Conclusion: DSCT coronary angiography has high diagnostic accuracy in assessing CAD among patients at intermediate to high risk without using heart rate-modulating premedication. DSCT is not superior to ICA for diagnosis of calcified segments.

    Blood concentrations of fibrinogen have been associated with coronary heart disease risk in epidemiological studies, but it is uncertain whether this association is causal or reflects residual confounding by other risk factors. We investigated the relationship between the single nucleotide polymorphism at position -148 in the beta-fibrinogen gene promoter (beta - 148C/T), blood fibrinogen levels, and risk of myocardial infarction (MI) in sufficiently large numbers of coronary disease cases to reliably address this question. Genotyping and measurement of blood fibrinogen concentration were carried out in 4,685 cases of confirmed MI and 3,460 controls with no history of coronary disease. A meta-analysis of ISIS and 19 other studies of beta-fibrinogen genotypes involving a total of 12,220 coronary disease cases and 18,716 controls was conducted. Among the ISIS controls, mean plasma fibrinogen concentrations with the C/C, C/T and T/T genotypes were 3.34 (SE 0.015), 3.48 (0.022), and 3.60 (0.064) g/l, respectively, corresponding to an increase of 0.14 (0.024) g/l per T allele (trend P Mendelian randomization), this association is not likely to be confounded by other factors. Consequently, these genetic results provide strong evidence that long-term differences in fibrinogen concentrations are not a major determinant of coronary disease risk.

    Full Text Available Fibrinogen can transform fibrin through an agglutination reaction, finally forming fibrin polymer with grid structure. The density and viscosity of the reaction system changes drastically during the course of agglutination. In this research, we apply an independently-developed piezoelectric agglutination sensor to detect the fibrinogen agglutination reaction in patients with coronary heart diseases. The terminal judgment method of determining plasma agglutination reaction through piezoelectric agglutination sensor was established. In addition, the standard curve between plasma agglutination time and fibrinogen concentration was established to determinate fibrinogen content quantitatively. The results indicate the close correlation between the STAGO paramagnetic particle method and the method of piezoelectric agglutination sensor for the detection of Fibrinogen. The correlation coefficient was 0.91 (γ = 0.91. The determination can be completed within 10 minutes. The fibrinogen concentration in the coronary heart disease group was significantly higher than that of the healthy control group (P < 0.05. The results reveal that high fibrinogen concentration is closely correlated to the incurrence, development and prognosis of coronary heart diseases. Compared with other traditional methods, the method of piezoelectric agglutination sensor has some merits such as operation convenience, small size, low cost, quick detecting, good precision and the common reacting agents with paramagnetic particle method.

    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.

    Congenital heart diseases (CHDs) are sometimes associated with coronary artery anomalies (CAAs). Accurate preoperative evaluation of coronary artery anatomy is essential for successful surgical repair of complex CHD. The aim of this study was to evaluate the incidence of congenital CAAs in patients with complex CHD at dual-source CT. Four hundred seventeen consecutive patients with complex CHD underwent contrast-enhanced cardiac CT angiography. The results were retrospectively analyzed, including the types and incidences of CAAs in various forms of complex CHD. Each patient was analyzed independently by 2 experienced cardiovascular radiologists. Image quality of coronary arteries was assessed on a 5-point scale with 2 or less being nondiagnostic. Thirty-five of 417 studies were nondiagnostic (8.39%). Sixty-three cases of CAA (15.11%) were detected by anomalous ostia and coronary arteries. CAA was involved in 6 of 108 patients with tetralogy of Fallot (5.56%), 18 of 84 patients with double outlet right ventricle (21.43%), 11 of 97 patients with pulmonary artery atresia (11.34%), 7 of 36 patients with transposition of the great arteries (22.22%), 15 of 41 patients with single ventricle (36.59%), 4 of 12 patients with truncus arteriosus/aortopulmonary window (33.33%), and 2 of 39 patients with interruption of the aortic arch/coarctation of the aorta (5.13%). Twenty of these were accompanied with an anomalous coronary course (31.74%). Patients with complex CHD have a higher prevalence of CAAs, which should be considered before surgery. Dual-source CT is an effective technique to visualize and evaluate complex CHD. Copyright © 2013 Society of Cardiovascular Computed Tomography. Published by Elsevier Inc. All rights reserved.

    The outcome of patients with chronic heart failure (CHF) following an ischaemic event is poorly understood. We evaluated the management and outcomes of CHF patients presenting with an acute coronary syndrome (ACS) and explored changes in outcomes over time. A total of 5556 patients enrolled in the Australia-New Zealand population of the Global Registry of Acute Coronary Events (GRACE) between 1999 and 2007 were included. Patients with CHF (n = 609) were compared with those without CHF (n = 4947). Patients with CHF were on average 10 years older, were more likely to be female, had more co-morbidities and cardiac risk factors, and were more likely to have a prior history of angina, myocardial infarction, and revascularization by coronary artery bypass graft (CABG) when compared with those without CHF. CHF was associated with a substantial increase in in-hospital renal failure [odds ratio (OR) 1.76, 95% confidence interval (CI) 1.15-2.71], readmission post-discharge (OR 1.47, 95% CI 1.17-1.90), and 6-month mortality (OR 2.25, 95% CI 1.55-3.27). Over the 9 year study period, in-hospital and 6 month mortality in those with CHF declined by absolute rates of 7.5% and 14%, respectively. This was temporally associated with an increase in prescription of thienopyridines, beta-blockers, statins, and angiotensin II receptor blockers, increased rates of coronary angiography, and 31.8% absolute increase in referral rates for cardiac rehabilitation. Acute coronary syndrome patients with pre-existing CHF are a very high risk group and carry a disproportionate mortality burden. Encouragingly, there was a marked temporal improvement in outcomes over a 9 year period with an increase in evidence-based treatments and secondary preventative measures.

    Cardiac rehabilitation (CR) is a secondary prevention program that offers education and support to assist patients with coronary heart disease (CHD) make lifestyle changes. Despite the benefits of CR, attendance at centre-based sessions remains low. Mobile technology (mHealth) has potential to reach more patients by delivering CR directly to mobile phones, thus providing an alternative to centre-based CR. The aim of this trial is to evaluate if a mHealth comprehensive CR program can improve adherence to healthy lifestyle behaviours (for example, physically active, fruit and vegetable intake, not smoking, low alcohol consumption) over and above usual CR services in New Zealand adults diagnosed with CHD. A two-arm, parallel, randomised controlled trial will be conducted at two Auckland hospitals in New Zealand. One hundred twenty participants will be randomised to receive a 24-week evidence- and theory-based personalised text message program and access to a supporting website in addition to usual CR care or usual CR care alone (control). The primary outcome is the proportion of participants adhering to healthy behaviours at 6 months, measured using a composite health behaviour score. Secondary outcomes include overall cardiovascular disease risk, body composition, illness perceptions, self-efficacy, hospital anxiety/depression and medication adherence. This study is one of the first to examine an mHealth-delivered comprehensive CR program. Strengths of the trial include quality research design and in-depth description of the intervention to aid replication. If effective, the trial has potential to augment standard CR practices and to be used as a model for other disease prevention or self-management programs.

    Full Text Available Abstract Background Patients with coronary heart disease often do not follow prescribed physical activity recommendations. The aim of this study was to assess the efficacy of a behavioural intervention to increase physical activity in patients with coronary heart disease not attending structured cardiac rehabilitation programmes. Methods Parallel randomised controlled trial comparing 6-month multi-component behavioural change intervention (n = 71 with usual care (n = 85 was conducted in two hospitals in Jordan, Middle East. Intervention included one face-to-face individualised consultation, 6 telephone support calls (for goal-setting, feedback and self-monitoring and 18 reminder text messages. Patients were randomly allocated to the two groups by opening opaque sealed sequence envelopes. The patients and the researcher who provided the intervention and assessed the outcomes were not blinded. Outcomes were assessed at baseline and 6 months. Primary outcome was physical activity level, secondary outcomes were blood pressure, body mass index, exercise self-efficacy for exercise and health-related quality of life. Results Intervention and control groups were comparable at baseline. Moderate physical activity significantly increased in the intervention group compared with control group (mean change (SD of frequency: 0.23 (0.87 days/week versus -.06 (0.40; duration: 15.53 (90.15 minutes/week versus −3.67 (22.60 minutes/week; intensity: 31.05 (105.98 Metabolic equivalents (METs versus 14.68 (90.40 METs.

    Full Text Available The case illustrates the possible link between coronary spasms, intraluminal thrombus formation, and widespread organized and layered thrombi in HTx patients. Furthermore, the case underlines the clinical value of OCT as a novel method for high-resolution vessel imaging in heart-transplanted (HTx patients with coronary spasms and suspected coronary artery disease. Coronary spasms and sudden death are frequent complications after HTx. The underlying mechanisms leading to these complications are unknown. The present case displays the clinical course of a 19-year-old HTx patient who was hospitalized due to acute myocardial infarction induced by severe coronary spasms. The patients remained unstable on conservative therapy. Therefore, an optical coherence tomography (OCT was performed and revealed massive, organized thrombi in the left main coronary artery, the circumflex coronary artery, and the left anterior descending coronary artery. The patient was stabilized after percutaneous coronary intervention. As a mural thrombus often goes undetected by coronary angiography, OCT may prove benefit in HTx patients with myocardial infarction or suspected coronary spasms.

    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.

    Background:Recent studies indicate an independent association of apolipoprotein(a) small phenotypes with the diabetes and the onset of coronary heart disease.Apolipoprotein(a)small phenotypes when used together with Lipoprotein(a) levels make powerful markers in assessing the actual risk of developing coronary heart disease in diabetic patients. Objectives: Evaluation of clinical and diagnostic significant of Lipoprotein(a) levels and apolipoprotein(a) small phenotypes and its relation to coronary heart disease in Sudanese diabetic patients. Setting and duration of study: Diabetic patients attending hospitals and medical centers from May 2011-December 2012, in Khartoum, Sudan. Patients and Methods: This was a case control, hospital based study done on 138 Sudanese diabetic patients attending hospitals and medical centers in Khartoum. Patients were divided into 2 groups. One group had diabetic cases with coronary heart disease and the other were diabetic patients without coronary heart disease. Controls were age and gender matched. Blood samples were collected from both groups(patients and controls) and were run for apolipoproteins, lipoproteins and apolipoprotein(a) small phenotype,low-density lipoprotein,high-density lipoprotein and trigeminal ganglia. Results: The levels of Lipoprotein(a) of patients were significantly higher than controls (p<0.05). Apolipoprotein(a)small phenotype distribution showed a significant difference when compared between patients of both groups (diabetics with and without coronary heart disease) and controls (p<0.05). Both low-density lipoprotein and high-density lipoprotein cholesterol showed significant difference in both patient groups and controls (p<0.05). Total cholesterol and triglyceride levels showed no significant difference between patients and controls. Apolipoprotein(a) small phenotypes showed significant distribution in diabetic patients when compared with coronary heart disease patients (more than one low molecular weight

    Cardiovascular diseases are the leading cause of death in Latin America, with ischemic heart disease as the principal cause in most countries. Risk factors for cardiovascular disease are highly prevalent in the region, but there are international variations in the pattern and level of risk factors. Overweight and obesity are increasing. In the 2012 Mexican National Survey, overweight or obesity was found in 64.9% of men and 73% of women, and they were strongly associated with sedentarism. The most characteristic dyslipidemia abnormality in the region is low high-density lipoprotein cholesterol, followed by elevated low-density lipoprotein cholesterol and increased levels of triglycerides. National diabetes mellitus prevalence ranges from 2.8% to 9.4% and tobacco smoking from 12.8% to 42%. According to the INTERHEART (A Study of Risk Factors for First Myocardial Infarction in 52 Countries and Over 27,000 Subjects) data for Latin America, the highest attributable risks for myocardial infarction were related to abdominal obesity, dyslipidemia, and smoking.

    Full Text Available Introduction: In spite of its importance as an experimental model, the information on the left coronary artery in pigs is sparse. Objective: To determine the morphologic features of the left coronary artery in pigs. Methods: We evaluated 158 pig hearts. The left coronary artery was perfused with synthetic resin after their ostia had been catheterized. Diameters and courses of the vascular beds were measured with an electronic caliper (Mitutoyo(r. Results: The diameter of left coronary artery was 6.98 ± 1.56 mm and its length was 3.51±0.99 mm. It was found to end up by bifurcating itself into the anterior interventricular artery and the circumflex artery in 79% of the cases, and by trifurcating in 21% of the cases, with the presence of the diagonal artery. The anterior interventricular artery ended up at the apex in 79.7% of the cases, and the circumflex artery at the posterior aspect of the left ventricle in 64% of the case, this artery never reached the posterior interventricular sulcus. An anastomosis between the terminal branches of the anterior interventricular artery and the posterior interventricular artery was found in 7.6% of the specimens. The antero-superior branch of the anterior interventricular artery occurred in 89.9% of the hearts. A left marginal branch was observed in 87.9% of the cases with a diameter of 2.25±0.55 mm. Conclusion: Compared with humans, pigs have shorter left coronary artery trunks and branches; even the circumflex artery never reaches the posterior interventricular sulcus. Our findings are useful for the design of experimental hemodynamic and procedural models.

    Revascularization decisions can profoundly impact patient survival, quality of life, and procedural risk. Although use of Heart Teams to make revascularization decisions is growing, data on their implementation in the real-world are limited. Our objective was to assess the prevalence of Heart Teams and their association with collaboration in routine practice. A survey of cardiologists and cardiac surgeons at 31 hospitals in Michigan was performed in May, 2011--prior to the recommendation for using Heart Teams in national guidelines. This survey included all percutaneous coronary intervention-performing hospitals in Michigan participating in the Blue Cross/Blue Shield of Michigan Cardiovascular Consortium and Michigan Society of Thoracic and Cardiovascular Surgeons Quality Collaborative. It targeted both the use of Heart Teams and multidisciplinary Case Conferences. There were 53 physician survey respondents from 27 hospitals with 4 hospitals not responding. Among respondents, 11 (40.7%) hospitals reported no Heart Teams or Case Conferences while 7 (25.9%) hospitals reported either a Heart Team or Case Conference. However, there was disagreement about the presence of a Heart Team at seven hospitals, and about Case Conferences at nine hospitals. Hospitals with definite Heart Teams reported significantly greater levels of collaboration between cardiologists and cardiac surgeons. The overall presence of Heart Teams prior to their recommendation in national guidelines was limited. Even among hospitals with a potential Heart Team, there was substantial disagreement between respondents about their presence. Further refinement of the definition of a Heart Team and measures of successful implementation are needed.

    Jeffrey Krauss

    Full Text Available BACKGROUND: Short telomere length (TL is an independent predictor of mortality in patients with coronary heart disease (CHD. However, the relationship between physical fitness and TL has not been explored in these patients. METHODS: In a cross sectional study of 944 outpatients with stable CHD, we performed exercise treadmill testing, assessed self-reported physical activity, and measured leukocyte TL using a quantitative PCR assay. We used generalized linear models to calculate mean TL (T/S ratio, and logistic regression models to compare the proportion of patients with short TL (defined as the lowest quartile, among participants with low, medium and high physical fitness, based on metabolic equivalent tasks achieved (METs. RESULTS: 229 participants had low physical fitness (7 METS. Mean ± T/S ratio ranged from 0.86±0.21 (5349±3781 base pairs in those with low physical fitness to 0.95±0.23 (5566±3829 base pairs in those with high physical fitness (p<.001. This association remained strong after adjustment for numerous patient characteristics, including measures of cardiac disease severity and physical inactivity (p = 0.005. Compared with participants with high physical fitness, those with low physical fitness had 2-fold greater odds of having TL in the lowest quartile (OR 2.39, 95% CI 1.60-3.55; p<.001. This association was similar after multivariable adjustment (OR 1.94, 95%CI, 1.18-3.20; p = 0.009. Self-reported physical inactivity was associated with shorter TL in unadjusted analyses, but not after multivariable adjustment. CONCLUSIONS: We found that worse objectively-assessed physical fitness is associated with shorter leukocyte telomere length in patients with CHD. The clinical implications of this association deserve further study.

    Heart-transplanted patients in Norway undergo annual coronary angiography (CA). The aims of this study were to establish a conversion factor between dose-area product and effective dose for these examinations and to use this to evaluate the accumulated radiation dose and risks associated with annual CA. An experienced cardiac interventionist performed a simulated examination on an Alderson phantom loaded with thermoluminescence dosemeters. The simulated CA examination yielded a dose-area product of 17 Gy cm 2 and an effective dose of 3.4 mSv: the conversion factor between dose-area product and effective dose was 0.20 mSv Gy cm -2 . Dose-area product values from 200 heart-transplanted patients that had undergone 906 CA examinations between 2001 and 2008 were retrieved from the institutional database. Mean dose-area product from annual CA was 25 Gy cm 2 , ranging from 2 to 140 Gy cm 2 . Mean number of CA procedure was 8 (range, 1-23). Mean accumulated effective dose for Norwegian heart-transplanted patients between 2001 and 2008 was 34 mSv (range, 5-113 mSv). Doses and radiation risks for heart-transplanted patients are generally low, because most heart transplantations are performed on middle-aged patients with limited life expectancy. Special concern should however be taken to reduce doses for young heart-transplanted patients who are committed to lifelong follow-up of their transplanted heart. (authors)

    Full Text Available Abstract Background Despite advances made in treating coronary heart disease (CHD, mortality due to CHD in Syria has been increasing for the past two decades. This study aims to assess CHD mortality trends in Syria between 1996 and 2006 and to investigate the main factors associated with them. Methods The IMPACT model was used to analyze CHD mortality trends in Syria based on numbers of CHD patients, utilization of specific treatments, trends in major cardiovascular risk factors in apparently healthy persons and CHD patients. Data sources for the IMPACT model included official statistics, published and unpublished surveys, data from neighboring countries, expert opinions, and randomized trials and meta-analyses. Results Between 1996 and 2006, CHD mortality rate in Syria increased by 64%, which translates into 6370 excess CHD deaths in 2006 as compared to the number expected had the 1996 baseline rate held constant. Using the IMPACT model, it was estimated that increases in cardiovascular risk factors could explain approximately 5140 (81% of the CHD deaths, while some 2145 deaths were prevented or postponed by medical and surgical treatments for CHD. Conclusion Most of the recent increase in CHD mortality in Syria is attributable to increases in major cardiovascular risk factors. Treatments for CHD were able to prevent about a quarter of excess CHD deaths, despite suboptimal implementation. These findings stress the importance of population-based primary prevention strategies targeting major risk factors for CHD, as well as policies aimed at improving access and adherence to modern treatments of CHD.

    The metabolic syndrome (MS) is a popularly used risk marker for coronary heart disease (CHD), yet its utility is in doubt. Cohort study based in Glasgow, Scotland, of 1471 men and women free of cardiovascular disease, followed up for a median of 13.7 years. MS was defined according to current criteria, requiring at least three of five dichotomous risk factors to be positive. Cox models were used to obtain hazard ratios (HRs) and discrimination was quantified by areas under receiver operating characteristic curves (AUCs) using 500 bootstrap samples. The HR (95% confidence interval) for CHD, MS versus no MS was 2.23 (1.67-2.97). However, the HR rose monotonically when plotted against the number of positive components, with no suggestion of a threshold effect at three positive components. Furthermore, the HR also changed monotonically as each of the five continuous variables defining the different components increased, again with no obvious threshold effects. The AUC for MS was low, at 0.5764, this being significantly (P<0.0001) lower than the AUCs for other risk prediction models, including the Framingham score, 0.7517. Although MS is related to CHD, there is no epidemiological justification for using it, rather than other criteria, as a risk predictor for CHD.

    The purpose of this study was to assess the relationships between an individual's characteristics and experiences (age, gender, level of education, income, and employment), knowledge of coronary heart disease (CHD) risk factors, perception of health status, awareness of CHD, and health promotion behaviors among adult Omanis. Using Pender's health promotion model, a cross-sectional and correlational survey design was employed. A self-administered questionnaire was distributed to 180 participants in Muscat, the capital of Oman. Descriptive and multivariate linear regression analyses were employed. Increasing age was associated with high levels of awareness about CHD. Participants who were employed and knowledgeable about CHD risk factors were more likely to have lower perceptions of health. The regression model showed that knowledge of CHD risk factors and awareness of CHD had positive associations with health promotion behaviors. Meanwhile, employed participants had lower health promotion behaviors scores. Interventions to increase health promotion behaviors should include application of behavioral change strategies that are suitable for age and employment status. The strategies must focus on providing information to enhance knowledge and awareness about CHD.

    Most studies examining potential associations between psychological factors and cardiovascular outcomes have focused on depression or anxiety. The effect of perceived stress on incident coronary heart disease (CHD) has yet to be reviewed systematically. We conducted a systematic review and meta-analysis of the association between perceived stress and incident CHD. Ovid, MEDLINE, and PsycINFO were searched as data sources. Prospective observational cohort studies were selected that measured self-reported perceived stress and assessed incident CHD at ≥6 months. We extracted study characteristics and estimates of the risk of incident CHD associated with high perceived stress versus low perceived stress. We identified 23 potentially relevant articles, of which 6 met our criteria (n = 118,696). Included studies measured perceived stress with validated measurements and nonvalidated simple self-report surveys. Incident CHD was defined as new diagnosis of, hospitalization for, or mortality secondary to CHD. Meta-analysis yielded an aggregate risk ratio of 1.27 (95% confidence interval 1.12 to 1.45) for the magnitude of the relation between high perceived stress and incident CHD. In conclusion, this meta-analysis suggests that high perceived stress is associated with a moderately increased risk of incident CHD. Copyright © 2012 Elsevier Inc. All rights reserved.

    To explore the differences in psychosocial risk factors related to coronary heart disease (CHD) between South Asian subgroups in the UK. South Asian people suffer significantly higher rates of CHD than other ethnic groups, but vulnerability varies between South Asian subgroups, in terms of both CHD rates and risk profiles. Psychosocial factors may contribute to the excess CHD propensity that is observed; however, subgroup heterogeneity in psychosocial disadvantage has not previously been systematically explored. With a cross-sectional design, 1065 healthy South Asian and 818 white men and women from West London, UK, completed psychosocial questionnaires. Psychosocial profiles were compared between South Asian religious groups and the white sample, using analyses of covariance and post hoc tests. Of the South Asian sample, 50.5% was Sikh, 28.0% was Hindu, and 15.8% was Muslim. Muslim participants were more socioeconomically deprived and experienced higher levels of chronic stress, including financial strain, low social cohesion, and racial discrimination, compared with other South Asian religious groups. In terms of health behaviors, Muslim men smoked more than Sikhs and Hindus, and Muslims also reported lower alcohol consumption and were less physically active than other groups. This study found that Muslims were exposed to more psychosocial and behavioral adversity than Sikhs and Hindus, and highlights the importance of investigating subgroup heterogeneity in South Asian CHD risk.

    Full Text Available Background: In the current study, we investigated the effect of physical activity (PA on the risk of coronary heart disease (CHD. Methods: In total, 146 cases of CHD and 157 matched controls were included in the study. Data on sociodemographics, lifestyle, and medical history factors were collected using an interviewer-administered questionnaire. A standard World Health Organization (WHO-based lifestyle questionnaire was used to assess PA. The risk of CHD was analyzed in relation to PA patterns using logistic regression. Results: Vigorous-intensity leisure PA was not associated with a lower risk of CHD. Subjects in the highest tertile of moderate occupational PA had a significantly lower risk of CHD compared to the lowest tertile (adjusted odds ratio (OR 0.31, 95% confidence intervals (CI 0.17–0.56. Subjects in the highest tertile of walking hasd an adjusted OR of 0.37 (95% CI 0.20–0.70.

    Background: Dietary guidelines recommend increasing fruit and vegetable intake and, most recently, have also suggested increasing variety. Objective: We prospectively examined the independent roles of quantity and variety in fruit and vegetable intake in relation to incident coronary heart disease (CHD). Design: We prospectively followed 71,141 women from the Nurses’ Health Study (1984–2008) and 42,135 men from the Health Professionals Follow-Up Study (1986–2008) who were free of diabetes, cardiovascular diseases, and cancer at baseline. Diet was assessed by using a validated questionnaire and updated every 4 y. Variety was defined as the number of unique fruit and vegetables consumed at least once per week. Potatoes, legumes, and fruit juices were not included in our definition of fruit and vegetables. Results: During follow-up, we documented 2582 CHD cases in women and 3607 cases in men. In multivariable analyses, after adjustment for dietary and nondietary covariates, those in the highest quintile of fruit and vegetable intake had a 17% lower risk (95% CI: 9%, 24%) of CHD. A higher consumption of citrus fruit, green leafy vegetables, and β-carotene– and vitamin C–rich fruit and vegetables was associated with a lower CHD risk. Conversely, quantity-adjusted variety was not associated with CHD. Conclusions: Our data suggest that absolute quantity, rather than variety, in fruit and vegetable intake is associated with a significantly lower risk of CHD. Nevertheless, consumption of specific fruit and vegetable subgroups was associated with a lower CHD risk. PMID:24088718

    Full Text Available Shexiang Baoxin Pill (SBP originated from a classical TCM Fufang Suhexiang Pill for chest pain with dyspnea in the Southern Song Dynasty (1107–110 AD. Here, we aimed to evaluate preclinical evidence and possible mechanism of SBP for experimental coronary heart disease (CHD. Studies of SBP in animal models with CHD were identified from 6 databases until April 2016. Study quality for each included article was evaluated according to the CAMARADES 10-item checklist. Outcome measures were myocardial infarction area, vascular endothelial growth factor (VEGF and microvessel count (MVC. All the data were analyzed by using RevMan 5.1 software. As a consequence, 25 studies with 439 animals were identified. The quality score of studies ranged from 2 to 5, with the median of 3.6. Meta-analysis of seven studies showed more significant effects of SBP on the reduction of the myocardial infarction area than the control (P < 0.01. Meta-analysis of eight studies showed significant effects of SBP for increasing VEGF expression compared with the control (P < 0.01. Meta-analysis of 10 studies indicated that SBP significantly improved MVC compared with the control (P < 0.01. In conclusion, these findings preliminarily demonstrated that SBP can reduce myocardial infarction area, exerting cardioprotective function largely through promoting angiogenesis.

    It is hypothesized that organizational stresses, such as high quantitative work load, responsibility for persons, poor relations with role senders, and contact with alien organizational territories, may be associated with high levels of psychological and physiological strain which are risk factors in coronary heart disease. It is further hypothesized that persons with coronary-prone Type A personality characteristics are most likely to exhibit strain under conditions of organizational stress. Measures of these stresses, personality traits, and strains were obtained from 205 male NASA administrators, engineers, and scientists. Type A personality measures included sense of time urgency, persistence, involved striving, leadership, and preference for competitive and environmentally overburdening situations.

    Free-breathing whole-heart coronary MR angiography (MRA) commonly uses navigators to gate respiratory motion, resulting in lengthy and unpredictable acquisition times. Conversely, self-navigation has 100% scan efficiency, but requires motion correction over a broad range of respiratory displacements, which may introduce image artifacts. We propose replacing navigators and self-navigation with a respiratory motion-resolved reconstruction approach. Using a respiratory signal extracted directly from the imaging data, individual signal-readouts are binned according to their respiratory states. The resultant series of undersampled images are reconstructed using an extradimensional golden-angle radial sparse parallel imaging (XD-GRASP) algorithm, which exploits sparsity along the respiratory dimension. Whole-heart coronary MRA was performed in 11 volunteers and four patients with the proposed methodology. Image quality was compared with that obtained with one-dimensional respiratory self-navigation. Respiratory-resolved reconstruction effectively suppressed respiratory motion artifacts. The quality score for XD-GRASP reconstructions was greater than or equal to self-navigation in 80/88 coronary segments, reaching diagnostic quality in 61/88 segments versus 41/88. Coronary sharpness and length were always superior for the respiratory-resolved datasets, reaching statistical significance (P < 0.05) in most cases. XD-GRASP represents an attractive alternative for handling respiratory motion in free-breathing whole heart MRI and provides an effective alternative to self-navigation.

Coronary flow reserve (CFR is a physiological index of coronary microcirculation and is noninvasively measured by transthoracic Doppler echocardiography (TTDE. This study aimed to investigate the effects of RIC on CFR in healthy subjects and patients with HF, through the assessment by TTDE. Methods: Ten patients with HF with left ventricular ejection fraction of less than 40%, and ten healthy volunteers were enrolled in this study. RIC treatment was performed twice a day for 1 week. Our custom-made RIC device was programmed to automatically conduct 4 cycles of 5 minutes inflation and 5 minutes deflation of a blood pressure cuff to create intermittent arm ischemia. CFR measurements and laboratory tests were examined before, and after 1 week of RIC treatment. Results: One week of RIC treatment was well tolerated in both groups. RIC treatment increased CFR from 4.0±0.9 to 4.6±1.3 (mean ± standard deviation in healthy subjects (P=0.02, and from 1.9±0.4 to 2.3±0.7 in patients with HF (P=0.03, respectively. Systolic blood pressure in healthy subjects, and heart rate in HF patients decreased after RIC treatment (both P<0.01. Conclusion: This study demonstrated that a 1 week course of RIC treatment improved coronary microcirculation in healthy subjects and patients with HF associated with reduced left ventricular ejection fraction.

    Lifestyle modification programmes for coronary heart disease patients have been shown to effectively improve risk factors and related health behaviours, quality of life, reincidence, and mortality. However, improvements in routine cardiac care over the recent years may offset the incremental benefit associated with older programmes. To determine the efficacy of lifestyle modification programmes for coronary heart disease patients developed over the last decade (1999-2009) by means of a systematic review and meta-analysis. The study included 23 trials (involving 11,085 randomized patients). Lifestyle modification programmes were associated with reduced all-cause mortality (summary OR 1.34, 95% CI 1.10-1.64), cardiac mortality (summary OR 1.48, 95% CI 1.17-1.88), and cardiac readmissions and non-fatal reinfarctions (summary OR 1.35, 95% CI 1.17-1.55). Furthermore, lifestyle modification programmes positively affected risk factors and related lifestyle behaviours at posttreatment (M = 10.2 months), and some of these benefits were maintained at long-term follow up (M = 33.7 months). Improvements in dietary and exercise behaviour were greater for programmes incorporating all four self-regulation techniques (i.e. goal setting, self-monitoring, planning, and feedback techniques) compared to interventions that included none of these techniques. The evidence summarized in this meta-analysis confirms the benefits of lifestyle modification programmes - over and above benefits achieved by routine clinical care alone.

    Surgical coronary revascularisation in children with congenital heart disease (CHD) is a rare event for which limited information is available. In this study, we review the indications and outcomes of surgical coronary revascularisation from the Pediatric Cardiac Care Consortium, a large US-based multicentre registry of interventions for CHD. This is a retrospective cohort study of children (coronary revascularisation between 1982 and 2011. In-hospital mortality and graft patency data were obtained from the registry. Long-term transplant-free survival through 2014 was achieved for patients with adequate identifiers via linkage with the US National Death Index and the Organ Procurement and Transplantation Network. Coronary revascularisation was accomplished by bypass grafting (n=72, median age 6.8 years, range 3 days-17.4 years) or other operations (n=65, median age 2.6 years, range 5 days-16.7 years) in 137 patients. Most revascularisations were related to the aortic root (61.3%) or coronary anomalies (27.7%), but 10.9% of them were unrelated to either of them. Twenty in-hospital deaths occurred, 70% of them after urgent 'rescue' revascularisation in association with another operation. Long-term outcomes were available by external linkage for 54 patients surviving to hospital discharge (median follow-up time 15.0 years, max follow-up 29.8 years) with a 15-year transplant-free survival of 91% (95% CI 83% to 99%). Surgical coronary revascularisation can be performed in children with CHD with acceptable immediate and long-term survival. Outcomes are dependent on indication, with the highest mortality in rescue procedures. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Objective. An appropriate psychological intervention to promote the level of mental health of patients with a coronary heart has a great importance. The existing investigation aimed to study the effectiveness of the behavioral-cognitive group therapy on depression, anxiety, and stress of patients with coronary heart disease. Methodology. The current study was quasi-experimental with a pretest-posttest that used a control group. Hence, 30 of the patients with coronary heart disease in Shahid Rajaee heart center in Tehran chose to use the convenience sampling method and were put in an experimental group and a control group. Both groups were pretested by using a demographic questionnaire, and scale of depression, anxiety, and stress DASS-42. Afterwards, the experimental group was trained for eight sessions of cognitive-behavioral club therapy and the control society gained no intervention. Later, both groups were post-tested, and the acquired information were analyzed by using inferential and descriptive statistical methods accompanied by SPSS 21 software. Findings. The results indicated that the cognitive-behavioral group therapy training significantly reduced depression, anxiety, and stress in patients with coronary heart disease. Conclusion. What should be understood from this study is that the cognitive-behavioral group therapy training had a great positive impact on the decrease of depression, anxiety, and tension in patients with coronary heart disease, since it had an economic cost and a great acceptability by the cases, especially when it was performed in a group.

    Tai Chi is a traditional Chinese conditioning exercise that has been used to integrate slow movements, controlled breathing, and mental concentration. The aim of the study was to determine whether Tai Chi training in addition to cardiac rehabilitation would result in a shift toward increased vagal activity of autonomic markers, such as baroreflex sensitivity (BRS) and heart rate variability (HRV). Twenty patients with coronary heart disease (CHD) (male/female: 13/7, mean age: 67.8 +/- 4.2 years, mean interval time after a coronary event: 19.8 months) completed this study. The Tai Chi group (n = 10) practiced supervised Tai Chi training once a week and home-based Tai Chi training three times a week together with conventional cardiac rehabilitation for one-year. The control group (n = 10) conducted the conventional cardiac rehabilitation only. BRS and HRV were evaluated at the baseline and after one-year of Tai Chi training. Compared with the controls, patients in the Tai Chi group showed statistically significant improvement in BRS (P = 0.036). These associations persisted after adjustment for age and other covariates. On the other hand, there were no significant trends seen in HRV. Additional Tai Chi training during cardiac rehabilitation may augment reflex vagal regulation, which adds importantly to knowledge of cardiac rehabilitation on autonomic regulation and clinical management of CHD.

    To quantify the impact of a commercial weight management program on weight change in obese patients with coronary heart disease. An observational, single-center pilot study in the Netherlands. Forty-five patients diagnosed with a recent acute coronary syndrome and a body mass index of >30 kg/m2 were recruited. The commercial weight management intervention (Weight Watchers) promotes a hypoenergetic and balanced diet, increased physical activity, and group support. The program included weekly 30-minute in-hospital meetings with an experienced coach. The program was offered in parallel with a cardiac rehabilitation program. Thirty-five patients completed the program. Of these patients, 32 patients (91%) decreased body weight. Mean weight change was -5.8 kg (range: +0.6 kg to -15.4 kg), and 20 patients (57%) achieved the target of 5% weight loss of their initial weight. Twenty-seven patients continued the commercial weight loss program after 14 weeks, the mean followup of these patients was 34 weeks and their mean weight change was -9.1 kg (range: 0.0-23.0 kg). Obese patients, discharged after an acute coronary syndrome, who were referred to a commercial weight management program, achieved significant weight loss. Although this is a nonrandomized pilot study with patients who were selected by motivation and by the ability to participate in the program, the proportion of weight loss is significant and promising.

    Socio-economic position and intelligence predict coronary heart disease but their mutual associations are not yet well understood. We investigated associations between intelligence and coronary heart disease mortality and explored if they are confounded or modified by socio-economic position. This was a cohort-based follow-up study. Data on intelligence, systolic and diastolic blood pressures and body mass index were measured at conscription examination at age 18 years in 682 361 Swedish men born 1951-1965. Data on parental and own education and social position were derived from censuses in 1960, 1970, 1980 and 1990. Follow-up data up to end of 2001 were derived from the Swedish Cause of Death Register and 737 coronary heart disease deaths were observed. Data were analyzed by Cox regression and conditional logistic regression models. An inverse association was found between intelligence and coronary heart disease mortality after adjustment for parental and own education and social position, body mass index and blood pressure (hazard ratio 0.92; 95% confidence interval 0.88-0.96). These associations were of similar strengths within all socio-economic categories and also found within 215 brother pairs discordant for coronary heart disease mortality and intelligence (odds ratio 0.76; 95% confidence interval 0.58-1.00). Intelligence is associated with coronary heart disease mortality independently of socio-economic position. Health education messages should be tailored according to intellectual performance of the recipients, but also other factors are important for socio-economic coronary heart disease inequalities.

    An X-ray intravital microscopy technique was developed to enable in vivo visualization of the coronary, cerebral, and pulmonary arteries in rats without exposure of organs and with spatial resolution in the micrometer range and temporal resolution in the millisecond range. We have refined the system continually in terms of the spatial resolution and exposure time. X-rays transmitted through an object are detected by an X-ray direct-conversion type detector, which incorporates an X-ray SATICON pickup tube. The spatial resolution has been improved to 6 μm, yielding sharp images of small arteries. The exposure time has been shortened to around 2 ms using a new rotating-disk X-ray shutter, enabling imaging of beating rat hearts. Quantitative evaluations of the X-ray intravital microscopy technique were extracted from measurements of the smallest-detectable vessel size and detection of the vessel function. The smallest-diameter vessel viewed for measurements is determined primarily by the concentration of iodinated contrast material. The iodine concentration depends on the injection technique. We used ex vivo rat hearts under Langendorff perfusion for accurate evaluation. After the contrast agent is injected into the origin of the aorta in an isolated perfused rat heart, the contrast agent is delivered directly into the coronary arteries with minimum dilution. The vascular internal diameter response of coronary arterial circulation is analyzed to evaluate the vessel function. Small blood vessels of more than about 50 μm diameters were visualized clearly at heart rates of around 300 beats/min. Vasodilation compared to the control was observed quantitatively using drug manipulation. Furthermore, the apparent increase in the number of small vessels with diameters of less than about 50 μm was observed after the vasoactive agents increased the diameters of invisible small blood vessels to visible sizes. This technique is expected to offer the potential for direct

    Dynamics of glucose concentration in human organism is an important diagnostic characteristic for it's parameters correlate significantly with the severity of metabolic, vessel and perfusion disorders. 36 patients with stable angina pectoris of II and III functional classes were involved in this study. All of them were men in age range of 45-59 years old. 7 patients hospitalized with acute myocardial infarction (aged from 49 to 59 years old) form the group of compare. Control group (n = 5) was of practically healthy men in comparable age. To all patients intravenous glucose solution (40%) in standard loading dose was injected. Capillary and vein blood samples were withdrawn before, and 5, 60, 120, 180 and 240 minutes after glucose load. At these time points blood pressure and glucose concentration were measured. In prepared blood smears shape, deformability and sizes of erythrocytes, quantity and degree of shear stress resistant erythrocyte aggregates were studied. Received data were approximated by polynomial of high degree to receive concentration function of studied parameters, which first derivative elucidate velocity characteristics of morphofunctional erythrocyte properties during intravenous glucose injection in patients with coronary heart disease and practically healthy persons. Received data show principle differences in dynamics of morphofunctional erythrocyte properties during intravenous glucose injection in patients with coronary heart disease as a possible mechanism of coronary blood flow destabilization.

    Acute coronary syndromes (ACS) may precipitate up to a third of acute heart failure (AHF) cases. We assessed the characteristics, initial management, and survival of AHF patients with (ACS-AHF) and without (nACS-AHF) concomitant ACS. Data from 620 AHF patients were analyzed in a prospective multicenter study. The ACS-AHF patients (32%) more often presented with de novo AHF (61% vs. 43%; P pulmonary edema were more common manifestations in ACS-AHF (P < .01 for both). Use of intravenous nitrates, furosemide, opioids, inotropes, and vasopressors, as well as noninvasive ventilation and invasive coronary procedures (angiography, percutaneous coronary intervention, coronary artery bypass graft surgery), were more frequent in ACS-AHF (P < .001 for all). Although 30-day mortality was significantly higher for ACS-AHF (13% vs. 8%; P = .03), survival in the 2 groups at 5 years was similar. Overall, ACS was an independent predictor of 30-day mortality (adjusted odds ratio 2.0, 95% confidence interval 1.07-3.79; P = .03). Whereas medical history and the manifestation and initial treatment of AHF between ACS-AHF and nACS-AHF patients differ, long-term survival is similar. ACS is, however, independently associated with increased short-term mortality. Copyright © 2014 Elsevier Inc. All rights reserved.

    As heart failure is a syndrome arising from another condition, such as coronary heart disease, it is rarely officially coded as the underlying cause of death regardless of the cause recorded by the physician at the time of certification. We sought to assess the true contribution of heart failure to overall mortality and coronary heart disease mortality and to examine how this contribution has changed over time. We carried out a retrospective analysis of all death certificates in Scotland between 1979 and 1992 for which heart failure was coded as the underlying or a contributory cause of death. From a total of 833622 deaths in Scotland between 1979 and 1992, heart failure was coded as the underlying cause in only 1.5% (13695), but as a contributory cause in a further 14.3% (126073). In 1979, 28.5% of male and 40.4% of female deaths attributed to coronary heart disease (coded as the underlying cause of death) also had a coding for heart failure. In 1992 these percentages had risen significantly to 34.1% and 44.8%, respectively (both Pheart failure as the underlying or contributory cause of death, standardized by age and sex, fell significantly over the period studied in all ages and in both sexes: by 31% in men and 41% in women or =65 years, respectively (Pheart failure is substantially underestimated by official statistics. Furthermore, one third or more of deaths currently attributed to coronary heart disease may be related to heart failure and this proportion appears to be increasing. While the absolute numbers of deaths caused by heart failure remains constant, this study is the first to show that standardized mortality rates are declining.

    In a ranking of the gross domestic product per capita in 2015, Belgium ranked 19th in the world according to the International Monetary Fun1d and the World Bank. It has a Human Development Index of 0.890, in which it is preceded by only 20 other countries in the world. This is, at least in part, due to a well-developed social security system on which all citizens can rely. Over the last 5-10 years, however, this system has come under increasing pressure. This has resulted in insufficient, incomplete and late reimbursement of all technologies that were introduced over the last ten years in the cathlab: intracoronary imaging techniques are not reimbursed at all, and FFR only to a vastly insufficient degree. For several structural heart interventions, a system of limited and incomplete reimbursement has recently been set up, with a requirement to organise these procedures within the frames of hospital networks. Numbers of PCIs have risen by 15% over the last four years, coinciding with an increase in the number of cathlabs by 50%, aiming at better access to primary PCI for STEMI patients. This has also resulted in a decrease in the average procedure volume per centre. Two thirds of PCIs are performed via the radial access. DES penetration has increased to 74%, approaching 100% in some centres, while the uptake of BRS has been very limited so far.

    There is a lack of studies on the knowledge and skills needed for patient education of individuals with coronary heart disease. Better understanding of what competencies health professionals see as necessary for patient education in secondary prevention can contribute to improved education of educators, and thus, improved patient education. The purpose of this study was to investigate health professionals' views on the knowledge and skills necessary in conducting high-quality patient education for adults recently diagnosed with coronary heart disease. A qualitative study was conducted using individual interviews with health professionals with experience from different types of patient education in cardiac care. The interviews were analysed using systematic text condensation. The informants were 19 Icelandic and Norwegian registered nurses, physiotherapists and cardiologists. Sound updated theoretical and clinical knowledge, along with advanced communication skills, was considered essential for patient education. This includes being able to establish interpersonal relationships with patients, capturing their learning needs, facilitating an effective dialogue and providing individualised patient centred education and lifestyle counselling. Evidence-based patient education requires knowledgeable health professionals with advanced communication skills and pedagogical competences that enable them to motivate patients and provide effective patient centred lifestyle counselling. © The European Society of Cardiology 2014.

Methods One hundred and twenty CHD patients with concomitant chronic kidney disease and receiving PCI in our hospital from Jan. 2000 to Jul. 2014, and 123 simple CHD patients without renal dysfunction, who had undergone PCI with concomitant IABP for the cardiac pump failure, cardiogenic shock, acute left heart failure, unstable angina pectoris (UP which was not allayed by medical treatment, or acute myocardial infarction (AMI, were selected for observation of preoperative condition, in-hospital mortality and prognosis of patients in two groups. Results There was no statistically significant difference in general clinical data including gender, age, and concomitant hypertension and diabetes, and preoperative blood lipid, AST, D-dimer, APTT, and international normalized ratio (INR showed also no statistically significant difference before surgery between two groups of patients (P>0.05. The difference in proportion of AMI, the left main trunk and (or three-branches involvement was of no statistical significance (P>0.05, but there was significant difference in the incidence of previous myocardial infarction, TnT, CK-MB, Cr, BUN, stent number, IABP application time (P0.05 between the two groups. Logistic regression analysis revealed that diabetes and the number of stents were independent risk factors for in-hospital and long-term mortalities. Conclusions By means of the effective cardiac assistance of IABP, CHD patients with renal insufficiency have the same short and long term clinical prognosis as simple CHD patients without renal dysfunction who has undergone PCI. Diabetes and the number of stents are independent risk factors for in-hospital and 1-year mortality. DOI: 10.11855/j.issn.0577-7402.2015.04.03

    IMPORTANCE Diabetes is associated with an elevated risk of coronary heart disease (CHD). Previous studies have suggested that the genetic factors predisposing to excess cardiovascular risk may be different in diabetic and non-diabetic participants. OBJECTIVE To identify genetic determinants of CHD that are specific to diabetic patients. DESIGN, SETTING, AND PARTICIPANTS We studied five independent sets of CHD cases and CHD-negative controls from the Nurses Health Study (NHS; enrolled in 1976 and followed through 2008), Health Professionals Follow-up Study (HPFS; enrolled in 1986 and followed through 2008), Joslin Heart Study (enrolled in 2001-2008), Gargano Heart Study (enrolled in 2001-2008), and Catanzaro Study (enrolled in 2004-2010). Included were a total of 1,517 CHD cases and 2,671 CHD-negative controls, all with type 2 diabetes. Results in diabetic patients were compared with those in 737 non-diabetic CHD cases and 1,637 non-diabetic CHD-negative controls from the NHS and HPFS cohorts. EXPOSURE 2,543,016 common genetic variants occurring throughout the genome. MAIN OUTCOME CHD defined as fatal or non-fatal myocardial infarction, coronary artery bypass grafting, percutaneous transluminal coronary angioplasty, or angiographic evidence of significant stenosis of the coronary arteries. RESULTS We identified a variant on chromosome 1q25 (rs10911021) consistently associated with CHD risk among diabetic participants with an odds ratio of 1.36 (95% confidence interval [CI] 1.22-1.51, P=2×10−8). No association between this variant and CHD was detected among non-diabetic participants (OR=0.99, P=0.89), consistent with a significant gene-by-diabetes interaction on CHD risk (P=2×10−4). As compared to protective allele homozygotes, rs10911021 risk allele homozygotes were characterized by a 32% decrease in the expression of the neighboring glutamate-ammonia ligase (GLUL) gene in human endothelial cells (P=0.0048). They also showed a decreased ratio between plasma

    Objectives The goal of this work was to reduce the scan time of contrast-enhanced whole-heart coronary magnetic resonance angiography (MRA) by using a gradient echo interleaved echo planar imaging (GRE-EPI) sequence at 3T field strength. Materials and Methods A GRE-EPI sequence was optimized to acquire contrast-enhanced whole-heart coronary MRA at 3T. First order phase correction was used for alignment of the odd and even echoes in the GRE-EPI echo train. Single and dual reference scan techniques for estimation of the linear phase correction parameters were evaluated using both phantom and volunteer studies. The GRE-EPI readout was combined with parallel imaging for a further reduction in scan time. To avoid image distortions, calibration signals for coil sensitivity estimation were acquired in a separate low resolution GRE scan prior to the whole-heart GRE-EPI scan. 8 healthy volunteers were scanned with the optimized contrast-enhanced GRE-EPI sequence. GRE-EPI images were acquired during slow infusion (0.3 ml/sec) of 0.1 mmol/kg body weight of Gd-BOPTA. For comparison purposes, the same 8 volunteers were scanned again in a separate scan session using a traditional GRE sequence with double the dose (0.2 mmol/kg body weight) of the same contrast agent with the same injection rate. The contrast-enhanced GRE-EPI and contrast-enhanced GRE techniques were compared in terms of relative SNR and CNR, image quality scores and visualized vessel lengths. Results Both, phantom and volunteer studies demonstrated that the dual reference scan phase correction technique was a key step for obtaining satisfactory image quality using GRE-EPI at 3T. Whole-heart coronary MRA with a spatial resolution of 1.0 × 1.0 × 2.0 mm3 was acquired with the GRE-EPI sequence in an average scan time of 2.5 ± 0.6 minutes, compared with 8.6 ± 2.7 minutes for the GRE technique. The GRE-EPI technique had lower relative CNR compared with the GRE sequence. The image quality and coronary artery

    Coronary heart disease preoperative diagnosis plays an important role in the treatment of vascular interventional surgery. Actually, most doctors are used to diagnosing the position of the vascular stenosis and then empirically estimating vascular stenosis by selective coronary angiography images instead of using mouse, keyboard and computer during preoperative diagnosis. The invasive diagnostic modality is short of intuitive and natural interaction and the results are not accurate enough. Aiming at above problems, the coronary heart disease preoperative gesture interactive diagnostic system based on Augmented Reality is proposed. The system uses Leap Motion Controller to capture hand gesture video sequences and extract the features which that are the position and orientation vector of the gesture motion trajectory and the change of the hand shape. The training planet is determined by K-means algorithm and then the effect of gesture training is improved by multi-features and multi-observation sequences for gesture training. The reusability of gesture is improved by establishing the state transition model. The algorithm efficiency is improved by gesture prejudgment which is used by threshold discriminating before recognition. The integrity of the trajectory is preserved and the gesture motion space is extended by employing space rotation transformation of gesture manipulation plane. Ultimately, the gesture recognition based on SRT-HMM is realized. The diagnosis and measurement of the vascular stenosis are intuitively and naturally realized by operating and measuring the coronary artery model with augmented reality and gesture interaction techniques. All of the gesture recognition experiments show the distinguish ability and generalization ability of the algorithm and gesture interaction experiments prove the availability and reliability of the system.

    Full Text Available Background: Traditional cardiovascular risk factors are strong predictors of an increased likelihood for premature CHD. Considering the benefits of risk factors᾿ management, it is imperative to find and treat them before looking for more unknown and weak risk factors. Objectives: Limited information is available about the demographic and historical characteristics of the patients with premature Coronary Heart Disease (CHD in IR Iran. The main objective of this study was to determine the prevalence of the traditional risk factors in these patients. Also, the researchers hypothesized that there are insufficient risk assessment and preventive intervention methods for the asymptomatic adult population. Methods: This study was conducted on 125 patients with premature CHD (age<50 years who were admitted in two academic hospitals with acute coronary syndromes. The patients were accepted since they had a definite CHD on the basis of acute myocardial infarction (elevated cardiac enzymes or documented CAD in coronary angiography. Results: The mean age of the study population was 42.50±5.65 (26 to 49 years. Among the patients,92 (73.6% were male, 113 (90.4% were married, 58 (46.4% were smokers,19 (15.2% were opium users, 97 (77.6% had dyslipidemia, 44 (35.2% had hypertension, and 33 (26.4% had diabetes mellitus. In addition, family history was presented in 54 patients (43.2%. Conclusions: Premature Coronary Heart Disease is a public health problem. However, there is lack of effective and intensive treatments of well-defined traditional risk factors and prevention methods for the majority of the patients experiencing premature CHD. In sum, there is still plenty of room for improvement of risk management in IR Iran.

    Objectives: The purpose of our study was to determine the relationship between the predictive factors and systolic reconstruction (SR) as an optimal reconstruction window in patients with low heart rate (LHR; less than 65 bpm). Methods: 391 patients (262 male and 129 female, mean age; 67.1 {+-} 10.1 years of age) underwent coronary CTA without the additional administration of a beta-blocker. Affecting factors for SR were analyzed in age, gender, body weight (BW), diabetes mellitus (DM), coronary arterial disease (CAD), ejection fraction (EF), systolic and diastolic body pressure (BP) and heart rate variability (HRV) during coronary CTA. Results: In 29 (7.4%) of the 391 patients, SR was needed, but there was no apparent characteristic difference between the systolic and diastolic reconstruction groups in terms of gender, age, BW, DM, CAD and EF. In a multivariate analysis, the co-existence of DM [P < 0.05; OR, 0.27; 95% CI, 0.092-0.80], diastolic BP [P < 0.01; OR, 0.95; 95% CI, 0.92-0.98] and HRV [P < 0.01; OR, 0.98; 95% CI, 0.96-0.99] were found to be the factors for SR. In gender-related analysis, HRV was an important factor regardless of sex, but co-existence of DM affected especially for female and BP for male. Conclusion: Especially in the patients with LHR who had a medication of DM, high HRV or high BP, SR, in addition to DR, was needed to obtain high-quality coronary CTA images.

    Increasing evidence shows the detrimental impact of high physical work demands for cardiovascular health and mortality. The aim of this study was to investigate the buffering effects of social support at work and job control in the relation between physical work demands and incidence of coronary events. The study included 14,337 middle-aged men free from coronary heart disease (CHD) at baseline. The sample consisted of a mixed occupational group recruited within 18 organizations from the manufacturing, service, and public sector. Data were collected through standardized questionnaires and clinical examinations. The incidence of clinical coronary events was monitored during a mean follow-up time of 3.15 years. Multilevel Cox proportional hazard regression modeling was used, adjusting for socio-demographic and classical coronary risk factors. Social support at work buffered the impact of physical work demands on CHD risk: Only among workers with low social support at work did physical work demands significantly increase the risk for CHD incidence (fully adjusted HR 2.50: 95 % CI 1.13-5.50), while this harmful effect completely disappeared in case of high level of workplace social support (fully adjusted HR 0.40; 95 % CI 0.09-1.70). No interaction or buffering effect with job control was observed. The results of our study suggest that supportive relationships at work may be a useful resource for reducing the cardiovascular risk associated with physical work demands in men. Future studies are needed to confirm this moderating role of workplace social support and to unravel the underlying mechanisms.

    Emerging data suggest that young women with coronary heart disease (CHD) are disproportionally vulnerable to the adverse cardiovascular effects of psychological stress. We hypothesized that younger, but not older, women with stable CHD are more likely than their male peers to develop mental stress-induced myocardial ischemia (MSIMI). We studied 686 patients (191 women) with stable coronary heart disease (CHD). Patients underwent (99m)Tc-sestamibi myocardial perfusion imaging at rest and with both mental (speech task) and conventional (exercise/pharmacological) stress testing. We compared quantitative (by automated software) and visual parameters of inducible ischemia between women and men and assessed age as an effect modifier. Women had a more-adverse psychosocial profile than men whereas there were few differences in medical history and CHD risk factors. Both quantitative and visual indicators of ischemia with mental stress were disproportionally larger in younger women. For each 10 years of decreasing age, the total reversibility severity score with mental stress was 9.6 incremental points higher (interaction, Pstress. Young women with stable CHD are susceptible to MSIMI, which could play a role in the prognosis of this group. © 2016 The Authors.

    In 45 patients with ischemic heart disease the results obtained by myocardial scintigraphy using technetium-99m diphosphonate (Tc-99m-DP) were compared with those obtained at selective coronary angiography and selective coronary perfusion scintigraphy. The cumulation of activity in the heart muscle was seen in twelve patients. This group is analyzed in the present paper in more detail. The ventriculographic examination of the left ventricle showed disturbed motility of the wall in six patients, of whom five had a positive myocardial scintigram. In view of this, myocardial scintigraphy using Tc-99m-DP may be considered a complementary, non-invasive method for proving significant disturbances of the motility of the heart wall. Positive myocardial scintigrams were also found in angna pectoris, in a patient after aorto-coronary bypass, in cardiomyopathy and myocarditis. In view of the fact that myocardial scintigraphy using Tc-99m-DP is capable of proving disturbances of cells of the heart muscle taking place at the moment, conclusions can be drawn as to the activity in the heart muscle. It further follows that myocardial scintigraphy may be significant in indicating the aorto-coronary bypass. We failed to prove an unequivocal correlation between myocardial scintigraphy, the number of sclerotically changed coronary vessels and the degree of their narrowing. An immediate relationship could not be proved between the extent of perfusion disturbance and the results of myocardial scintigraphy

    To assess the effect of systolic data acquisition for electrocardiography (ECG)-triggered high-pitch computed tomography (CT) on motion artefacts of coronary arteries in patients with high heart rates (HRs). Eighty consecutive patients (15 women, age 67 {+-} 14 years) with HR {>=}70 bpm underwent CT angiography of the thoracic aorta (CTA) on 128-slice dual-source CT in ECG-triggered high-pitch acquisition mode (pitch = 3.2) set at 60% (group A, n = 40) or 30% (group B, n = 40) of the RR interval. Two blinded readers graded coronary artery image quality on a three-point scale. Radiation doses were calculated. Inter-observer agreement in grading image quality of the 1,154 coronary segments was good ({kappa} = 0.62). HRs were similar in groups A and B (85 {+-} 13 bpm vs 85 {+-} 14 bpm, p not significant). Significantly fewer coronary segments with non-diagnostic image quality occurred (i.e. score 3) in group B than in group A [2.8% (16/579) vs 8.3% (48/575), p < 0.001]. Seventeen patients (42.5%) of group A and 12 patients (30.0%) of group B had at least one non-diagnostic segment. Effective radiation doses were 2.3 {+-} 0.3 mSv for chest CTA. A systolic acquisition window for high-pitch dual-source CTA in patients with high HRs ({>=}70 bpm) significantly improves coronary artery image quality at a low radiation dose. (orig.)

    Full Text Available Background: Obesity is a well-known principal risk factor for metabolic disorders and cardiovascular diseases. Resistin is one of adipocyte-derived molecules, which plays important roles in inflammation as well as in endocrine and cardiovascular systems. Objectives: The present study aimed to determine the association between serum resistin level and presence/severity of Coronary Heart Disease (CHD. Patients and Methods: This cross-sectional study was conducted on 155 individuals referred for coronary angiography. Information about the patients’ age, gender, and cardiovascular risk factors was recorded. Their weight, height, and waist and hip circumferences were measured, as well. Each coronary angiogram was reported for two scoring methods (number of vessel diseases (usual method and Gensini scoring system by one cardiologist who was not aware of the participants’ serum resistin levels. Then, the relationship between serum resistin level and presence/severity of CHD was evaluated. Results: The results revealed no significant associations between the mean serum resistin level and the presence of CHD by both methods of evaluation of the coronary angiograms after adjustment for all conventional risk factors for CHD. In addition, no significant association was detected between serum resistin level and the severity of CHD based on the usual method of reporting the coronary angiograms (number of vessel diseases (P = 0.332. Yet, serum resistin level was positively correlated to body mass index and waist and hip circumferences and negatively related to height and fasting blood sugar level. Moreover, no linear correlation was found between serum resistin level and Gensini score (P = 0.35. Finally, hip circumference (P = 0.002 and height (P = 0.018 were determined as the predictors of serum resistin level. Conclusions: This cross-sectional study showed no significant associations between serum resistin level and presence/severity of CHD.

    Several studies have demonstrated the tremendous potential of using coronary artery calcium (CAC) in addition to traditional risk factors for coronary heart disease (CHD) risk prediction. However, to date, no risk score incorporating CAC has been developed. The goal of this study was to derive and validate a novel risk score to estimate 10-year CHD risk using CAC and traditional risk factors. Algorithm development was conducted in the MESA (Multi-Ethnic Study of Atherosclerosis), a prospective community-based cohort study of 6,814 participants age 45 to 84 years, who were free of clinical heart disease at baseline and followed for 10 years. MESA is sex balanced and included 39% non-Hispanic whites, 12% Chinese Americans, 28% African Americans, and 22% Hispanic Americans. External validation was conducted in the HNR (Heinz Nixdorf Recall Study) and the DHS (Dallas Heart Study). Inclusion of CAC in the MESA risk score offered significant improvements in risk prediction (C-statistic 0.80 vs. 0.75; p < 0.0001). External validation in both the HNR and DHS studies provided evidence of very good discrimination and calibration. Harrell's C-statistic was 0.779 in HNR and 0.816 in DHS. Additionally, the difference in estimated 10-year risk between events and nonevents was approximately 8% to 9%, indicating excellent discrimination. Mean calibration, or calibration-in-the-large, was excellent for both studies, with average predicted 10-year risk within one-half of a percent of the observed event rate. An accurate estimate of 10-year CHD risk can be obtained using traditional risk factors and CAC. The MESA risk score, which is available online on the MESA web site for easy use, can be used to aid clinicians when communicating risk to patients and when determining risk-based treatment strategies.

    Background Although psychological interventions are recommended for the management of coronary heart disease (CHD), there remains considerable uncertainty regarding their effectiveness. Design Systematic review and meta-analysis of randomised controlled trials (RCTs) of psychological interventions for CHD. Methods The Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, CINAHL and PsycINFO were searched to April 2016. Retrieved papers, systematic reviews and trial registries were hand-searched. We included RCTs with at least 6 months of follow-up, comparing the direct effects of psychological interventions to usual care for patients following myocardial infarction or revascularisation or with a diagnosis of angina pectoris or CHD defined by angiography. Two authors screened titles for inclusion, extracted data and assessed risk of bias. Studies were pooled using random effects meta-analysis and meta-regression was used to explore study-level predictors. Results Thirty-five studies with 10,703 participants (median follow-up 12 months) were included. Psychological interventions led to a reduction in cardiovascular mortality (rfcelative risk 0.79, 95% confidence interval [CI] 0.63 to 0.98), although no effects were observed for total mortality, myocardial infarction or revascularisation. Psychological interventions improved depressive symptoms (standardised mean difference [SMD] -0.27, 95% CI -0.39 to -0.15), anxiety (SMD -0.24, 95% CI -0.38 to -0.09) and stress (SMD -0.56, 95% CI -0.88 to -0.24) compared with controls. Conclusions We found that psychological intervention improved psychological symptoms and reduced cardiac mortality for people with CHD. However, there remains considerable uncertainty regarding the magnitude of these effects and the specific techniques most likely to benefit people with different presentations of CHD.

    Epidemiological data regarding the association between ABO blood groups and risk of coronary heart disease (CHD) have been inconsistent. We sought to investigate the associations between ABO blood group and CHD risk in prospective cohort studies. Two large, prospective cohort studies (the Nurses' Health Study [NHS] including 62 073 women and the Health Professionals Follow-up Study [HPFS] including 27 428 men) were conducted with more than 20 years of follow-up (26 years in NHS and 24 years in HPFS). A meta-analysis was performed to summarize the associations from the present study and previous studies. In NHS, during 1 567 144 person-years of follow-up, 2055 participants developed CHD; in HPFS, 2015 participants developed CHD during 517 312 person-years of follow-up. ABO blood group was significantly associated with the risk of developing CHD in both women and men (log-rank test; P=0.0048 and 0.0002, respectively). In the combined analysis adjusted for cardiovascular risk factors, compared with participants with blood group O, those with blood groups A, B, or AB were more likely to develop CHD (adjusted hazard ratios [95% CI] for incident CHD were 1.06 [0.99-1.15], 1.15 [1.04-1.26], and 1.23 [1.11-1.36], respectively). Overall, 6.27% of the CHD cases were attributable to inheriting a non-O blood group. Meta-analysis indicated that non-O blood group had higher risk of CHD (relative risk =1.11; 95% CI, 1.05-1.18; P=0.001) compared with O blood group. These data suggest that ABO blood group is significantly associated with CHD risk. Compared with other blood groups, those with the blood type O have moderately lower risk of developing CHD.

We therefore compared plasma IL-6 (a key cytokine in the inflammatory process), fibrin D-dimer (a marker of fibrin turnover), and coagulation factors VII and XIIa (initiators of extrinsic and intrinsic blood coagulation, respectively) as predictors of coronary risk in the West of Scotland Coronary Prevention Study of pravastatin in men with hypercholesterolemia. 485 men who had had a coronary event (nonfatal myocardial infarction, death from coronary heart disease, or revascularization) were matched for age and smoking status with 934 controls. Baseline IL-6 and D-dimer were strong univariate predictors of coronary risk (relative risk in the highest quintile approximately twice that in the lowest quintile) and were associated with each other and with C-reactive protein. On multivariate analyses, D-dimer retained a significant association with coronary risk (relative risk, 1.86; 95% CI, 1.24 to 2.80), whereas IL-6 (1.47; 0.95 to 2.28) and C-reactive protein (1.33; 0.85 to 2.08) did not. Neither factor VII nor factor XIIa antigens were predictors of coronary events. Fibrin D-dimer may be a stronger predictor of coronary risk than inflammatory markers, perhaps through its ability to stimulate monocyte release of IL-6.

    OBJECTIVE: It is a common notion that coronary heart disease (CHD) is rare among the Inuit, possibly due to a high intake of omega-3-fatty acids. The scientific evidence for this is weak and to some extent based on uncertain mortality statistic. The aim of this study was to assess the prevalence...... in Greenland. Blood tests were supplemented by structured interviews, anthropometry, and measurements of blood pressure, and the participants received an oral glucose tolerance test. RESULTS: The prevalence of symptomatic CHD (AP, self-reported MI) was 7.3% among men and 6.9% among women, and 12.2% and 13...

    Scavenger receptor BI (SR-BI) is the major receptor for high-density lipoprotein (HDL) cholesterol (HDL-C). In humans, high amounts of HDL-C in plasma are associated with a lower risk of coronary heart disease (CHD). Mice that have depleted Scarb1 (SR-BI knockout mice) have markedly elevated HDL......-C levels but, paradoxically, increased atherosclerosis. The impact of SR-BI on HDL metabolism and CHD risk in humans remains unclear. Through targeted sequencing of coding regions of lipid-modifying genes in 328 individuals with extremely high plasma HDL-C levels, we identified a homozygote for a loss-of-function...

    This study examines sociodemographic differences in myocardial infarction (MI) risk perceptions among people with coronary heart disease (CHD) (N = 3130). Two variables for comparative risk perceptions were computed: (1) own risk compared to that of an average person; and (2) own risk compared...... to that of an average person with CHD. Comparative optimism in MI risk perceptions was common, particularly among men and those with higher education. CHD severity and psychosocial resources mediated these sociodemographic differences. These results suggest challenges for secondary prevention in CHD, particularly...

    To analyze the concept of risk in relation to coronary heart disease (CHD) among Filipino-Americans (FAs) and provide a new definition of risk. Published literature. This concept analysis provided a new meaning of risk in relation to CHD among FAs and shed light on further understanding of risk. Risk has been laced with negativity in health care, but based on the current literature, risk can be conceptualized in a positive perspective, especially in the area of chronic health disease such as CHD. However, further research is needed in the conceptualization of risk related to CHD for consistency, adequacy, and meaning. © 2010 Wiley Periodicals, Inc.

    Full Text Available Background Rehabilitation following acute myocardial infarction (AMI is a crucial part of secondary prevention for coronary heart disease. The aim of our study was to determine the efficiency of our national in-patient rehabilitation program in improving exercise capacity and lowering risk factors for coronary heart disease.Methods 25 patients 3-9 weeks after AMI, undergoing 2 week in-patient cardiac rehabilitation, were included in our study. We performed exercise stress testing and measurement of classic risk factors before and after the rehabilitation. Classic risk factors were compared with 25 age matched adults without known risk factors for coronary heart disease.Results Patients after AMI had lower exercise capacity than healthy adults (p≤0.002 for double product, maximal load, systolic blood pressure, heart rate and time of load. Patients recieved appropriate drug therapy after myocardial infarction, which presented as lower diastolic and a trend to lower systolic blood pressure (p=0.002 and 0.080, lower total and LDL cholesterol values (both p<0.001 than healthy adults, but higher values of metabolic syndrome parameters (higher waist cifcumference p=0.045, higher hip-waist ratio, lower HDL cholesterol, both p<0.001, and a trend to higher body mass index. Although we observed significant increases in exercise capacity (higher, maximal load, systolic blood pressure,double product and time of load, all p≤0.003, no changes in classic risk factors during rehabilitaiton were demonstrated.Conclusions In-patient program of cardiac rehabilitation efficiently elevates exercise capacity in patients after AMI, but fails to influence classic risk factors for coronary heart disease, which might be due to lack of controlled cardioprotective diet during rehabilitation.

    BACKGROUND: Saturated fatty acid (SFA) intake increases plasma LDL-cholesterol concentrations; therefore, intake should be reduced to prevent coronary heart disease (CHD). Lower habitual intakes of SFAs, however, require substitution of other macronutrients to maintain energy balance. OBJECTIVE: We...... fatty acids or carbohydrates should replace energy from SFAs to prevent CHD. DESIGN: This was a follow-up study in which data from 11 American and European cohort studies were pooled. The outcome measure was incident CHD. RESULTS: During 4-10 y of follow-up, 5249 coronary events and 2155 coronary deaths...... occurred among 344,696 persons. For a 5% lower energy intake from SFAs and a concomitant higher energy intake from PUFAs, there was a significant inverse association between PUFAs and risk of coronary events (hazard ratio: 0.87; 95% CI: 0.77, 0.97); the hazard ratio for coronary deaths was 0.74 (95% CI: 0...

    Systematic reviews examining associations of depressive disorder with coronary heart disease and stroke produce mixed results. Failure to consider reverse causation and dose-response patterns may have caused inconsistencies in evidence. This prospective cohort study on depressive disorder, coronary heart disease, and stroke analysed reverse causation and dose-response effects using four 5-year and three 10-year observation cycles (total follow up 24 years) based on multiple repeat measures of exposure. Participants in the Whitehall II study (n = 10,036, 31,395 person-observations, age at start 44.4 years) provided up to six repeat measures of depressive symptoms via the 30-item General Health Questionnaire (GHQ-30) and one measure via Center for Epidemiologic Studies Depression Scale (CES-D). The cohort was followed up for major coronary events (coronary death/nonfatal myocardial infarction) and stroke (stroke death/morbidity) through the national mortality register Hospital Episode Statistics, ECG-screening, medical records, and self-report questionnaires. GHQ-30 caseness predicted stroke over 0-5 years (age-, sex- and ethnicity-adjusted HR 1.60, 95% CI 1.1-2.3) but not over 5-10 years (HR 0.94, 95% CI 0.6-1.4). Using the last 5-year observation cycle, cumulative GHQ-30 caseness was associated with incident coronary heart disease in a dose-response manner (1-2 times a case: HR 1.12, 95% CI 0.7-1.7; 3-4 times: HR 2.06, 95% CI 1.2-3.7), and CES-D caseness predicted coronary heart disease (HR 1.81, 95% CI 1.1-3.1). There was evidence of a dose-response effect of depressive symptoms on risk of coronary heart disease. In contrast, prospective associations of depressive symptoms with stroke appeared to arise wholly or partly through reverse causation.

    Major depressive disorder (MDD) associated with acute coronary syndrome (ACS) increases the risk of mortality. Decreased heart rate variability (HRV), also a predictor of mortality, is reduced in patients with MDD after ACS, and has been suggested to be a mediator of MDD mortality after ACS. Although selective serotonin reuptake inhibitors may reduce mortality post-ACS, little is known about their effects on HRV. To examine the influence of both sertraline and improvement in mood on HRV. The Sertraline Antidepressant Heart Attack Randomized Trial assessed HRV from 24-hour Holter electrocardiogram recordings at baseline in 290 patients and from a second recording in 258 of these patients 16 weeks after randomization to sertraline or placebo. Frequency domain measures of HRV included high-frequency power, low-frequency power, very low-frequency power, ultra low-frequency power, and total power. Depression severity was measured by the Hamilton Rating Scale for Depression. Clinical response was measured with the Clinical Global Impressions Improvement scale. At baseline, prior episodes of MDD were associated with lower HRV. Sertraline significantly increased ultra low-frequency power, while improvement in mood was associated with higher low-frequency power independent of treatment. However, the expected recovery in HRV following ACS was not observed in patients with MDD. Higher ultra low-frequency during sertraline treatment and higher low-frequency power in patients whose mood improved resulted primarily from these measures decreasing in their comparison groups. Heart rate variability recovery is impaired in depressed patients after ACS. Previously reported differences in baseline HRV between patients with and without depression after ACS grew larger in the 16 weeks following a coronary event. Both sertraline treatment and symptomatic recovery from depression were associated with increased HRV compared with placebo-treated and nonrecovered post-ACS control groups

    Full Text Available OBJECTIVES: To describe the ERICO study (Strategy of Registry of Acute Coronary Syndrome, a prospective cohort to investigate the epidemiology of acute coronary syndrome. METHODS: The ERICO study, which is being performed at a secondary general hospital in São Paulo, Brazil, is enrolling consecutive acute coronary syndrome patients who are 35 years old or older. The sociodemographic information, medical assessments, treatment data and blood samples are collected at admission. After 30 days, the medical history is updated, and additional blood and urinary samples are collected. In addition, a retinography, carotid intima-media thickness, heart rate variability and pulse-wave velocity are performed. Questionnaires about food frequency, physical activity, sleep apnea and depression are also applied. At six months and annually after an acute event, information is collected by telephone. RESULTS: From February 2009 to September 2011, 738 patients with a diagnosis of an acute coronary syndrome were enrolled. Of these, 208 (28.2% had ST-elevation myocardial infarction (STEMI, 288 (39.0% had non-ST-elevation myocardial infarction (NSTEMI and 242 (32.8% had unstable angina (UA. The mean age was 62.7 years, 58.5% were men and 77.4% had 8 years or less of education. The most common cardiovascular risk factors were hypertension (76% and sedentarism (73.4%. Only 29.2% had a prior history of coronary heart disease. Compared with the ST-elevation myocardial infarction subgroup, the unstable angina and non-ST-elevation myocardial infarction patients had higher frequencies of hypertension, diabetes, prior coronary heart disease (p<0.001 and dyslipidemia (p = 0.03. Smoking was more frequent in the ST-elevation myocardial infarction patients (p = 0.006. CONCLUSIONS: Compared with other hospital registries, our findings revealed a higher burden of CV risk factors and less frequent prior CHD history.

    Global methylation level in blood leukocyte DNA has been associated with the risk of coronary heart disease (CHD), with inconsistent results in various populations. Similar data are lacking in Chinese population where different genetic, lifestyle and environmental factors may affect DNA methylation and its risk relationship with CHD. To examine whether global methylation is associated with the risk of CHD in Chinese population. A total of 334 cases with CHD and 788 healthy controls were included. Global methylation in blood leukocyte DNA was estimated by analyzing LINE-1 repeats using bisulfite pyrosequencing. In an initial analysis restricted to control subjects, LINE-1 level reduced significantly with aging, elevated total cholesterol, and diagnosis of diabetes. In the case-control analysis, reduced LINE-1 methylation was associated with increased risk of CHD; analysis by quartile revealed odds ratios (95%CI) of 0.9 (0.6-1.4), 1.9 (1.3-2.9) and 2.3 (1.6-3.5) for the third, second and first (lowest) quartile (P{sub trend} < 0.001), respectively, compared to the fourth (highest) quartile.
