    Atrial fibrillation(AF) is the most common type of sustained arrhythmia,which is now on course to reach epidemic proportions in the elderly population. AF is a commonly encountered comorbidity in patients with cardiac and major non-cardiac diseases. Morbidity and mortality associated with AF makes it a major healthcare burden. The objective of our article is to determine the prognostic impact of AF on acute coronary syndromes,heart failure and chronic kidney disease. Multiple studies have been conducted to determine if AF has an independent role in the overall mortality of such patients. Our review suggests that AF has an independent adverse prognostic impact on the clinical outcomes of acute coronary syndromes,heart failure and chronic kidney disease.

    The hypothesis that chronic kidney disease (CKD) is associated with increased coronary artery calcification (CAC) was tested using data from the Dallas Heart Study, a representative sample of Dallas County residents aged 30 to 65 yr. CKD was defined as presence of microalbuminuria and GFR > or =60 ml/min per 1.73 m(2) (stage 1 to 2), or GFR 10, >100, and >400 versus scores 100 (odds ratio, 2.85; 95% confidence interval, 0.92 to 8.80) and >400 (odds ratio, 8.35; 95% confidence interval, 1.94 to 35.95) in the total population after adjustment for covariates, but these associations were substantially reduced after exclusion of participants with diabetes. Participants with diabetes and stage 3 to 5 CKD had a ninefold increased odds of CAC scores >10 versus scores 10 in the nondiabetic population. In conclusion, stage 3 to 5 CKD is associated with increased CAC scores, but this association may be substantially stronger among adults with diabetes. These findings need to be confirmed in study populations that include adults >65 yr of age and a larger number of CKD cases. PMID:15601745

    Full Text Available Aim. To define influence of the left ventricle (LV perfusion defects on the clinical status dynamics after coronary angioplasty in patients with the expressed myocardium dysfunction of ischemic etiology. Materials and methods. Examined 86 patients (81 men and 5 women aged from 46 to 73 years before and in 2–3 days after percutaneous coronary intervention with diagnosis: CAD, CHF with NYHA class III–IV, echocardiography parameters of LV: ejection fraction less than 40%, end-diastolic volume is more than 200 ml. Perfusion defects of myocardium estimated with use of ECG-gated single photon emission computed tomography. Predictors were defined: perfusion defects on LV apex (in score, perfusion defects in the area of LAD, LCx and RCA (%, the LV global perfusion defects (in score and %. Results. In 42% of cases 6-minute walk test increased to 3 times; The NYHA class decreased by 2 classes (group 1. In 28 cases 6-minute walk test increased to 2 times and the NYHA class decreased on 1 class. In 22 patients 6-minute walk test increased less than 50% of reference values and there was no dynamics NYHA class (50 patients of the group 2. Initial extent of LV global perfusion defects in group 1 – 41,2 ± 4,0%, in group 2 – 58,3 ± 2,4% (р = 0,0004. Similar values are received for perfusion indicators in the area of LAD and the LV apex. Prevalence of myocardial perfusion defects at rest reflects prevalence of a cardiosclerosis in a cardiac muscle. Conclusion. Degree of LV myocardial perfusion defects in patients with the expressed heart failure of ischemic etiology is the key indicator influencing clinical efficiency of coronary angioplasty. Critical size for definition of the favorable forecast of revascularization are 60% and more perfusion defects testifying that in a cardiac muscle the focal cardiosclerosis prevails over the functioning myocardium. 

  14. Coronary heart disease, chronic inflammation, and pathogenic social hierarchy: a biological limit to possible reductions in morbidity and mortality.

    We suggest that a particular form of social hierarchy, which we characterize as "pathogenic", can, from the earliest stages of life, exert a formal analog to evolutionary selection pressure, literally writing a permanent developmental image of itself upon immune function as chronic vascular inflammation and its consequences. The staged nature of resulting disease emerges "naturally" as a rough analog to punctuated equilibrium in evolutionary theory, although selection pressure is a passive filter rather than an active agent, like structured psychosocial stress. Exposure differs according to the social constructs of race, class, and ethnicity, accounting in large measure for observed population-level differences in rates of coronary heart disease across industrialized societies. American Apartheid, which enmeshes both majority and minority communities in a social construct of pathogenic hierarchy, appears to present a severe biological limit to continuing declines in coronary heart disease for powerful as well as subordinate subgroups: "Culture"--to use the words of the evolutionary anthropologist Robert Boyd--"is as much a part of human biology as the enamel on our teeth".

    Full Text Available Objective To explore the clinical efficacy of intra-aortic balloon pump (IABP as an auxiliary treatment of percutaneous coronary intervention (PCI in patients with coronary heart disease (CHD associated with chronic kidney disease. 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

    Objective To investigate the chronic low back pain and coronary heart disease relationship, after adjusting for relevant confounders, including genetics. Methods In a cross-sectional design, 2148 twins were recruited from the Murcia Twin Registry, Spain. The exposure was chronic LBP and the outcomes were myocardial infarction and other coronary heart diseases—lifetime and in the last 2 years–based on standardized health-related questionnaires. First, logistic regression analysis investigated associations of the total sample followed by a matched co-twin control analyses, with all complete twin pairs discordant for chronic LBP utilised, separated for zygosity—dizygotic (DZ) and monozygotic (MZ) pairs, which adjusted for shared familial factors, including genetics. Results Chronic LBP pain is associated with lifetime myocardial infarction [odds ratio (OR) = 2.69, 95% confidence interval (CI) = 1.35–5.36], other coronary heart diseases over a lifetime (OR = 2.58, 95% CI: 1.69–3.93) and in the last two years (OR = 2.19, 95% CI: 1.33–3.60), while there was a borderline association with myocardial infarction in the last 2 years (OR = 2.64, 95% CI: 0.98–7.12). Although the magnitude of the association remained or increased in the co-twin control analyses, none reached statistical significance. Conclusion Chronic LBP is associated with a higher prevalence of myocardial infarction and coronary heart disease. It is possible that this association remains even when controlling for genetics and early shared environment, although this should be investigated with larger samples of twins discordant for LBP.

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

    2016-08-01

    Elevated heart rate is known to induce myocardial ischaemia in patients with coronary artery disease (CAD), and heart rate reduction is a recognized strategy to prevent ischaemic episodes. In addition, clinical evidence shows that slowing the heart rate reduces the symptoms of angina by improving microcirculation and coronary flow. Elevated heart rate is an established risk factor for cardiovascular events in patients with CAD and in those with chronic heart failure (HF). Accordingly, reducing heart rate improves prognosis in patients with HF, as demonstrated in SHIFT. By contrast, data from SIGNIFY indicate that heart rate is not a modifiable risk factor in patients with CAD who do not also have HF. Heart rate is also an important determinant of cardiac arrhythmias; low heart rate can be associated with atrial fibrillation, and high heart rate after exercise can be associated with sudden cardiac death. In this Review, we critically assess these clinical findings, and propose hypotheses for the variable effect of heart rate reduction in cardiovascular disease. PMID:27226153

    Serum neutrophil gelatinase-associated lipocalin (NGAL) is recognized as a useful biomarker for acute kidney injury. Recently, elevated NGAL levels were reported in patients with heart failure and cardiac events, but the association between serum NGAL and severity of coronary artery disease (CAD) has not been investigated adequately. This study aimed to evaluate the association between serum NGAL concentration and CAD severity in patients without heart failure and chronic kidney disease. Two-hundred thirteen patients [mean age: 66.2 ± 9.2 (SD)] without heart failure and chronic kidney disease (estimated glomerular filtration rate >60 mL/min/1.73 m(2)) who underwent coronary angiography were retrospectively analyzed using the SYNTAX score. The mean concentration of serum NGAL was 134.3 ± 111.3 ng/mL. A statistically significant correlation was observed between serum NGAL levels and the SYNTAX score (R = 0.18, P = 0.0091). Multivariable analysis also showed elevated serum NGAL as an independent risk factor for a high SYNTAX score (P 100 ng/mL) and high levels of BNP (>25 pg/mL) had a higher SYNTAX score (low-low vs. high-high: 13.8 ± 13.4 vs. 20.8 ± 18.9, P heart failure. Serum NGAL might be a biomarker for CAD severity.

    2013-01-01

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

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

    Ischemic heart disease holds first place in WHO mortality statistics. Thanks to recent technical developments in computer tomography (CT), it is now possible to examine the heart, and the coronary arteries in particular, with sufficient temporal and spatial resolution. Native examination of the heart including identification of coronary calcification has an effect on the risk stratification of asymptomatic patients in addition to classification of conventional risk factors. Contrast-enhanced CT coronary angiography can identify and quantify stenoses and localize non-calcified plaques. Furthermore, it is possible to evaluate coronary artery anatomy, vessel grafts and, to a lesser degree, coronary stents. (orig.) [German] Die ischaemische Herzkrankheit steht auf Platz 1 der WHO-Todesursachenstatistik. Dank der technischen Entwicklungen in der Computertomographie (CT) der letzten Jahre ist es inzwischen moeglich, das Herz und v. a. die Koronararterien mit diagnostisch ausreichender oertlicher und zeitlicher Aufloesung zu untersuchen. Die native Untersuchung des Herzens mit Bestimmung der Koronararterienkalklast ist - neben der Einstufung durch konventionelle Risikofaktoren - ein Faktor in der Risikostratifizierung von asymptomatischen Patienten.

The periodontal screening index was used to quantify the degree of periodontal disease. We compared the findings to those in the general population with use of data from the 4th German Dental Health Survey. Gingivitis, moderate periodontitis, and severe periodontitis were present in 17 (24%), 17 (24%), and 37 (52%) patients, respectively. Severe periodontitis was more prevalent among chronic heart failure patients than in the general population. In contrast, moderate periodontitis was more prevalent in the general population (P <0.00001). The severity of periodontal disease was not associated with the cause of chronic heart failure or the severity of heart failure symptoms. Six-minute walking distance was the only independent predictor of severe periodontitis. Periodontal disease is highly prevalent in chronic heart failure patients regardless of the cause of heart failure. Prospective trials are warranted to clarify the causal relationship between both diseases.

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

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.

  7. Imaging techniques in the diagnosis of coronary heart disease

    International Nuclear Information System (INIS)

    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.

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

    Objective: To investigate the relationship between anemia and heart function in hospitalized patients with chronic heart failure caused by coronary heart disease. Methods: Patients with chronic heart failure caused by coronary heart disease, who were hospitalized in the Second Hospital of Tianjin Medical University between December 2005 and January 2007, were included in this study. Based on hemoglobin (Hb) levels, patients were divided into anemia group and non-anemia group. The relationship of the incidence data and the cardiac functions was retrospectively analyzed between two groups. Results: There were 1 816 patients in this study, and the proportion of male and female patients with anemia were 16.34% (151/925) and 17.28% (154/891) respectively. The average age was higher in patients of anemia group than that of the non-anemia gronp (t = 6.823, P < 0.01). The proportion of ≥60 years of age was higher in patients of anemia group than that of non-anemia group (x2=13.312, P < 0.01 ). With the progression of the heart function classification, the value of hemoglobin had a lower gradually trend, and the proportion of anemia had a higher gradually trend. There was a negative correlation between the heart function classification and the value of hemoglobin ( r= -0.192, P <0.05). The value of left ventricular end diastolic diameter (LVEDD) was higher, but interventricular septum thickness (IVS) was lower. in patients of anemia group than that of non-anemia group. The majority proportion of left ventricular ejection fraction (LVEF)was ≤0.45 in patients of anemia group. The proportion of E/A ≤ 1 was significantly higher than E/A>1 in patients of two groups.Conclusion: The chronic heart failure should be treated with the correction of anemia at the same time. which could significantly improve the prognosis of patients with chronic heart failure.%目的:探讨冠心病慢性心力衰竭住院患者贫血与心功能之间的

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

Despite remarkable developments and achievements in the field of coronary intervention, such as percutaneous catheter intervention and coronary bypass surgery, the mortality from coronary heart disease remains high because of lack of effective cardioprotective therapy against ischemia/reperfusion injury after coronary recanalization. The mitochondria play a crucial role in determination of cell death in ischemia/reperfusion injury, and furthermore provide myocardial protection against ischemia/reperfusion injury by ischemic preconditioning. Functional and structural alterations in the mitochondria help to decide cell death and survival, and many investigations have been conducted to explore the pathophysiological mechanisms of “mitochondrial remodeling” to gain clues regarding ischemia/reperfusion injury. In this review, we summarize the current state of knowledge concerning the pathophysiological role of bidirectional (detrimental and defensive “mitochondrial remodeling” via which cell death or survival is determined in coronary heart disease. Further, we discuss clinical trials of mitochondria-targeted treatment in patients with coronary heart disease.Keywords: coronary heart disease, mitochondrial remodeling, mitochondrial dynamics

    Full Text Available There is an increasing need for percutaneous revascularization procedures of coronary Chronic Total Occlusion (CTO, because many patients with severe coronary artery disease have limited options for revascularization. Although the success rate of percutaneous revascularization of CTOs was unsatisfactory from the 1990s to the 2000s, recent technological advances in interventional strategies have improved the success rate to 85%. Detailed histological assessment of human autopsy studies of CTO has contributed significantly to the refinement in Percutaneous Coronary Intervention (PCI techniques and device development. We have recently reported the pathological findings and characteristics of CTOs that occur in different clinical scenarios. In this review, we discuss the pathology of CTOs to facilitate greater understanding of revascularization strategies for CTOs.

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

    Background Glucocorticoid signaling exerts major roles in inflammation, metabolism and depression, which are three crucial factors accompanying or underlying coronary heart disease. Although accumulating evidence indicates the influence of glucocorticoids on the pathology and treatment of coronary heart disease, there is still a dearth of pharmaceutical mechanisms for this relationship. This study aimed to investigate the influence of drug treatment on glucocorticoid receptor levels in coronary heart disease.Methods Eighty hospitalized patients (average age (59.0 7.5) years, 46 male and 34 female) with coronary heart disease were categorized into four groups with 20 members in each according to one of the four drugs they were treated with. The four drugs were: nitrated derivative isosorbide dinitrate, the beta-adrenergic receptor blocker metoprolol, the calcium antagonist nifedipine, and the HMG-CoA reductase inhibitor lovastatin. Glucocorticoid receptor protein levels of peripheral blood lymphocytes were tested using immunoblotting analysis before and after one month of treatment. Results Immunoblotting analysis showed increased glucocorticoid receptor levels after treatment with metoprolol and nifedipine. There were no statistically significant changes of glucocorticoid receptor levels after treatment with isosorbide dinitrate or lovastatin, although there were trends of up-regulation of glucocorticoid receptor expression after both treatments.Conclusions Both the beta-blocker and the calcium blocker can increase glucocorticoid receptor levels after chronic administration. This effect suggests a mechanism for their anti-inflammatory and other therapeutic roles for coronary heart disease and comorbid disorders.

    Chronic coronary heart disease (cCHD) is characterized by atherosclerosis, which progressively narrows the coronary artery lumen and impairs myocardial blood flow. Restoration of occluded coronary vessels with newly formed collaterals remains an ideal therapeutic approach due to the need for redirecting blood flow into the ischemic heart. In this study, we investigated the effect of an active fraction isolated from Geum joponicum (AFGJ) on angiogenesis in cCHD hearts. Our results demonstrated that AFGJ not only enhanced capillary tube formation of endothelial cells, but also promoted the growth of new coronary collaterals (at the diameter 0.021-0.21 mm) in the ischemic region of hearts in rat cCHD model. Our study also indicated that the growth of new collaterals in ischemic hearts resulted in improved functional recovery of the cCHD hearts as demonstrated by ECG and echocardiography analyses. These data suggest that AFGJ may provide a novel therapeutic method for effective treatment of cCHD.

    Background Passive smoking is a major risk factor for coronary heart disease (CHD), and existing estimates are out of date due to recent and substantial changes in the level of exposure. Objective To estimate the annual clinical burden and cost of CHD treatment attributable to passive smoking. Outcome measures Annual attributable CHD deaths, myocardial infarctions (MI), total CHD events, and the direct cost of CHD treatment. Methods A Monte Carlo simulation estimated the CHD events and costs as a function of the prevalence of CHD risk factors, including passive-smoking prevalence and a low (1.26) and high (1.65) relative risk of CHD due to passive smoking. Estimates were calculated using the CHD Policy Model, calibrated to reproduce key CHD outcomes in the baseline Year 2000 in the U.S. Results At 1999–2004 levels, passive smoking caused 21,800 (SE=2400) to 75,100 (SE=8000) CHD deaths and 38,100 (SE=4300) to 128,900 (SE=14,000) MIs annually, with a yearly CHD treatment cost of $1.8 (SE=$0.2) to $6.0 (SE=$0.7) billion. If recent trends in the reduction in the prevalence of passive smoking continue from 2000 to 2008, the burden would be reduced by approximately 25%–30%. Conclusions Passive smoking remains a substantial clinical and economic burden in the U.S. PMID:19095162

    2009-09-01

    Insomnia is highly prevalent in patients with chronic disease including chronic heart failure (CHF) and is a significant contributing factor to fatigue and poor quality of life. The pathophysiology of CHF often leads to fatigue, due to nocturnal symptoms causing sleep disruption, including cough, orthopnea, paroxysmal nocturnal dyspnea, and nocturia. Inadequate cardiac function may lead to hypoxemia or poor perfusion of the cerebrum, skeletal muscle, or visceral body organs, which result in organ dysfunction or failure and may contribute to fatigue. Sleep disturbances negatively affect all dimensions of quality of life and is related to increased risk of comorbidities, including depression. This article reviews insomnia in CHF, cardiac medication side-effects related to sleep disturbances, and treatment options. PMID:18758945

    2005-01-01

    Smoking is the leading preventable cause of illness and premature death in Germany, claiming over 110,000 lives a year because it directly increases the risk of dying from heart disease, stroke, emphysema and a variety of cancers. The overwhelming majority of smokers begin tobacco use before they reach adulthood. Among those young people who smoke, the average age is now 13-14. In Germany, about 39% of male and 31% of female adults (age 18-60 years) continue to smoke, despite information about the unequivocally negative health consequences of smoking. The exact mechanisms of smoking-related vascular disease are not yet known. Smoking causes acute hemodynamic alterations such as increase in heart rate, systematic and coronary vascular resistance, myocardial contractility, and myocardial oxygen demand. These short-term effects could lower the ischemic threshold in smokers with coronary artery disease and contribute to the increased risk for acute cardiovascular events. Endothelial damage is thought to be an initiating event in atherosclerosis and early studies have demonstrated that long-term smoking has direct toxic effects with structural changes of human endothelial cells. Recent research has shown the importance of the functional role of the endothelium in regulating vascular tone, platelet-endothelial interactions, leukocyte adhesion and smooth muscle cell proliferation via synthesis and release of a variety of substances such as nitric oxide. There is strong evidence that smoking leads to endothelial dysfunction mainly by increased inactivation of nitric oxide by oxygen-derived free radicals. Smoking also increases oxidative modification of LDL and is associated with lower HDL plasma levels. Smoking induces a systemic inflammatory response with increased leukocyte count and elevation of the C-reactive protein level. Importantly, the prothrombotic effects of smoking have been repeatedly demonstrated to cause alterations in platelet function, imbalance of

    The article presents an assessment of degree and type of atherosclerosis of coronary and non-coronary vessels in old patients with ischemic heart disease associated with chronic viral hepatitis C (VHC), the incidence of myocardial infarction and the possibility of participation chronic VHC in atherogenesis. Patients with ischemic heart disease have correlation of atherosclerosis of arteries with age, hypercholesterinemia. Patients without chronic VHC more often give a higher risk of myocardial infarction, especially in early period (1-1,5 years) of onset of ischemic heart disease clinical implications. Patients with ischemic heart disease associated with chronic viral hepatitis C more often have generalized alterations in vessels, multifocal type of alteration. So, participation of VHC in atherogenesis is most probably connected with maintenance of chronic immune inflammation in vascular endothelium.

    Full Text Available Objective: to establish the relationship of chronic generalized periodontitis, multiple cavities and dentofacial anomalies with various forms of coronary heart disease and its complications. Material and methods. The study included 294 patients with coronary heart disease and its complications. The patients were divided into two groups. Group I included 89 patients with acute Q-myocardial infarction, which was placed in the presence of at least 2 of the following criteria identified on the basis of a comprehensive clinical and instrumental examination: clinical, laboratory confirmation (CK-MB, electrocardiographic signs of damage or myocardial necrosis. The following statistical methods were used: multi-variate and univariate analysis of variance, non-parametric tests, crosstabulation, chi-square test, Fisher»s exact test. As a measure of variability of the normal distribution standard deviation was used. Results. It is noted that in patients with myocardial infarction more likely than in patients without coronary heart attack in history severe generalized periodontitis, dentofacial anomalies and multiple dental caries have appeared. In patients with acute myocardial infarction, severe periodontal disease has been associated with increased fibrinogen levels in the blood and an increase in the dispersion of the interval QT, which are known to be indicators of poor prognosis in acute coronary disease.

    Full Text Available Background: The coronary sinus is a dilated venous channel opening into the right atrium of the heart. The coronary venous system has gained importance in recent years for electrophysiological procedures like arrhythmia ablation, biventricular pacing and implantation of cardiac pacemakers. The present study aims to study the formation and tributaries of coronary sinus and also the morphology of thebesian valve. Materials and Methods: 30 formalin fixed cadaveric hearts available in the department of Anatomy, Dhanalakshmi Srinivasan Medical College and Hospital, Perambalur, Tamil nadu, was used for the study. The formation and tributaries of coronary sinus were noted. The length of coronary sinus in millimeters was measured from the union of great cardiac vein and left marginal vein upto the opening of the coronary sinus in the right atrium with vernier calipers. The width of the coronary ostium in the right atrium was measured in millimeters with vernier calipers. Results: In 93.33% specimens the coronary sinus was formed by the union of great cardiac vein and left marginal vein. In 3.33% specimens it was formed by the union of great cardiac vein and posterior vein of left ventricle, and in 3.33% specimens it was formed by the union of great cardiac vein and oblique vein of left atrium. The left marginal vein was absent in 2 specimens and small cardiac vein was absent in 1 specimen. The mean length of coronary sinus was 54.98 + 12.2mm. The mean width of coronary sinus ostium was 9.35 + 3.24mm. The Thebesian valve was present in 93.33% specimens and it was semilunar in shape. Conclusion: The knowledge of coronary sinus anatomy will be helpful during electrophysiological procedures.

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

  8. Cereal grains and coronary heart disease.

    Truswell, A S

    2002-01-01

    Cereal grains and their products provide around 30% of total energy intake in British adults, (much more than any of the other major food groups). Coronary heart disease (CHD) is the largest single cause of death in Britain and many other Western countries. This review examines the question whether there is a relation between cereal consumption and CHD. Several of the nutrients in cereals have known potential for reducing risk factors for CHD: the linoleic acid, fibre, vitamin E, selenium and folate. Cereals also contain phytoestrogens of the lignan family and several phenolic acids with antioxidant properties. Processing generally reduces the content of these nutrients and bioprotective substances. Although cereals at the farm gate are very low in salt, processed cereal foods, eg bread and some breakfast cereals, are high-salt foods and thus could contribute to raising blood pressure. Human experiments have clearly shown that oat fibre tends to lower plasma total and LDL cholesterol but wheat fibre does not. Rice bran and barley may also lower cholesterol but most people do not eat enough barley to have an effect. Cereal foods with low glycaemic index such as pasta and oats are beneficial for people with diabetes and might lower plasma lipids. Between 1996 and 2001 an accumulation of five very large cohort studies in the USA, Finland and Norway have all reported that subjects consuming relatively large amounts of whole grain cereals have significantly lower rates of CHD. This confirms an earlier report from a small British cohort. The protective effect does not seem to be due to cholesterol-lowering. While cohort studies have shown this consistent protective effect of whole grain cereals, there has been (only one) randomised controlled secondary prevention trial of advice to eat more cereal fibre. In this there was no reduction of the rate of reinfarction. The trial had some weaknesses, eg there were eight different diets, compliance was not checked objectively

With age, “atherosclerotic plaques”—deposits of fats, calcium, and various cellular waste products—coat the walls of arteries, causing them to narrow and harden, interrupting blood flow through the body. When this occurs in the coronary arteries, which nourish the heart muscle, the end result is CHD. If a plaque breaks off the arte...

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

    2007-12-01

    Full Text Available Abstract Background Glycated haemoglobin (HbA1c, blood pressure and body mass index (BMI are risk factors for albuminuria, the latter in turn can lead to hyperlipidaemia. We used novel statistical analyses to examine how albuminuria and chronic kidney disease (CKD may influence the effects of other risk factors on coronary heart disease (CHD. Methods A prospective cohort of 7067 Chinese type 2 diabetic patients without history of CHD enrolled since 1995 were censored on July 30th, 2005. Cox proportional hazard regression with restricted cubic spline was used to auto-select predictors. Hazard ratio plots were used to examine the risk of CHD. Based on these plots, non-linear risk factors were categorised and the categorised variables were refitted into various Cox models in a stepwise manner to confirm the findings. Results Age, male gender, duration of diabetes, spot urinary albumin: creatinine ratio, estimated glomerular filtration rate, total cholesterol (TC, high density lipoprotein cholesterol (HDL-C and current smoking status were risk factors of CHD. Linear association between TC and CHD was observed only in patients with albuminuria. Although in general, increased HDL-C was associated with decreased risk of CHD, full-range HDL-C was associated with CHD in an A-shaped manner with a zenith at 1.1 mmol/L. Albuminuria and CKD were the main contributors for the paradoxically positive association between HDL-C and CHD for HDL-C values less than 1.1 mmol/L. Conclusion In type 2 diabetes, albuminuria plays a linking role between conventional risk factors and CHD. The onset of CKD changes risk associations between lipids and CHD.

    2015-01-01

    In this review,we discussed the findings and concepts underlying the potential role of Helicobacter pylori(H.pylori) infections in the initiation,development or persistence of atherosclerosis and coronary heart disease(CHD).This Gram-negative bacterium was described by Marshall and Warren in 1984.The majority of infected subjects carries and transmits H.pylori with no symptoms; however,in some individuals these bacteria may cause peptic ulcers,and even gastric cancers.The widespread prevalence of H.pylori infections and the fact that frequently they remain asymptomatic may suggest that,similarly to intestinal microflora,H.pylori may deliver antigens that stimulate not only local,but also systemic inflammatory response.Recently,possible association between H.pylori infection and extragastric disorders has been suggested.Knowledge on the etiology of atherosclerosis together with current findings in the area of H.pylori infections constitute the background for the newly proposed hypothesis that those two processes may be related.Many research studies confirm the indirect association between the prevalence of H.pylori and the occurrence of CHD.According to majority of findings the involvement of H.pylori in this process is based on the chronic inflammation which might facilitate the CHDrelated pathologies.It needs to be elucidated,if the infection initiates or just accelerates the formation of atheromatous plaque.

  18. Depression and coronary artery disease -real heart attack

    International Nuclear Information System (INIS)

    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)

    Full Text Available BACKGROUND Chronic Heart Failure (CHF represents worldwide a clinical condition with increasing prevalence, high social, economical and epidemiological impact. Even if new pharmacological and non-pharmacological approachs have been recently used, mortality remains high in general population and quality of life is poor in these patients. DISCUSSION The association between CHF and sleep disorders is frequent but still undervalued: sleep apnoeas in CHF produce negative effects on cardiovascular system and an aggravation of prognosis. CPAP (Continuous Positive Airway Pressure is commonly used to treat sleep apnoeas in patients without cardiac involvement and it is also used in first line treatment of acute cardiogenic pulmonary oedema thanks to its hemodynamic and ventilatory effects. The addition of nightly CPAP to standard aggressive medical therapy in patients with CHF and sleep apnoeas reduces the number of apnoeas, reduces the blood pressure, and the respiratory and cardiac rate, reduces the activation of sympathetic nervous system, the left ventricular volume and the hospitalization rate; besides CPAP increases the left ventricular ejection fraction, amd the oxygenation, it improves quality of life, tolerance to exercise and seems to reduce mortality in patients with a higher apnoeas suppression. CONCLUSIONS These implications suggest to investigate sleep apnoeas in patients with CHF in order to consider a possible treatment with CPAP. Further studies need to be developed to confirm the use of CPAP in patients with CHF without sleep disorders.

    Full Text Available Background: Relationships between cardiac murmurs detected during physical examination and coronary heart disease mortality among the general population are not well described. Aims: To assess the relationship between cardiac murmurs detected during physical examination and coronary heart disease mortality. Methods and Results: This relationship was examined with Cox regression analyses of data from 7990 adults, aged 30–75 years, from the Second National Health and Nutrition Examination Survey Mortality Study (1976–1992. Covariates included age, race, sex, history of CVD, diabetes, probable left ventricular hypertrophy, serum cholesterol, body mass index, blood pressure, and smoking status. During 16.8 follow-up years, there were 457 deaths from coronary heart disease (CHD (ICD-9 410–414 and 661 deaths from diseases of the heart (ICD-9 390–398, 402, 404, 410–414, 415–417, 420–429. A systolic murmur was present in 420 persons and a diastolic murmur was present in 56 persons at baseline. Persons with a heart murmur were at increased risk of death from CHD (relative risk=1.7, 95% confidence interval=1.2, 2.5 and from diseases of the heart (RR=2.2, 95% CI=1.6, 2.9 after multivariate adjustment for cardiovascular disease risk factors. Similar results were observed when murmur intensity (i.e., murmur grade was accounted for. Conclusions: These results suggest that the presence of a heart murmur may be associated with an increased risk for mortality from both CHD and diseases of the heart.

A variety of causes, including donor heart characteristics, recipient risk factors, and immune-mediated influences, are associated with developing CAV. In this review, we will focus on the pathophysiology of developing CAV and various methods to screen for this condition. The pathogenesis of CAV likely involves repeated injuries to the endothelium from a variety of factors such as cellular-mediated rejection, and alloimmune factors, including antibody-mediated injury, ischemia-reperfusion injury at time of transplant, cytomegalovirus infections, immunosuppression medications, systemic inflammation, and traditional atherosclerosis risk factors. Patients with significant CAV are often asymptomatic, and therefore early detection by routine screening prior to graft dysfunction is crucial. There are a variety of invasive, noninvasive, and blood tests that have been studied as screening methods, and we will discuss the role of each of these in this review article. Although some treatment regimens have been established for CAV, this is an area where further studies and research are necessary.Keywords: cardiac allograft vasculopathy, orthotopic heart transplantation, intra-vascular imaging

    Marijuana is the most abused recreational drug in the United States. Cannabinoids, the active ingredients of marijuana, affect multiple organ systems in the human body. The pharmacologic effects of marijuana, based on stimulation of cannabinoid receptors CB1 and CB2, which are widely distributed in the cardiovascular system, have been well described. Activation of these receptors modulates the function of various cellular elements of the vessel wall, and may contribute to the pathogenesis of atherosclerosis. Clinically, there are reports linking marijuana smoking to the precipitation of angina and acute coronary syndromes. Recently, large published clinical trials with CB1 antagonist rimonabant did not show any significant benefit of this agent in preventing progression of atherosclerosis. In light of these findings and emerging data on multiple pathways linking cannabinoids to atherosclerosis, we discuss the literature on the role of cannabinoids in the pathophysiology of atherosclerosis. We also propose a marijuana paradox, which implies that inhalation of marijuana may be linked to precipitation of acute coronary syndromes, but modulation of the endocannabinoid system by a noninhalation route may have a salutary effect on the development of atherosclerosis.

    Full Text Available Background/Aim. Numerous studies have provided clear and convincing evidence that psychosocial factors contribute to the pathogenesis and expression of coronary heart disease (CHD. These factors have been related to the following psychosocial domains: personality factors and character traits, depression, anxiety, social isolation and chronic life stress. The aim of this study was to estimate the influence of personality traits and psychosocial risk factors for the development of coronary heart disease. Methods. The investigation was conducted as observational cross-sectional (case-control study. Based on medical records all subjects were divided into two groups: the group of patients with CHD (61 participants, and the control group of 41 healthy participants. All participants fulfilled the Eysenck Inventory Questionnaire, Paykel stress scale and Bortner scale of A-B self-estimation. Results. The participants with CHD were shown to have lower education than healthy participants, but were comparable by gender, age and place of residence. According to the Bortner scale, most participants with CHD expressed type A personality, whereas most healthy participants expressed types B and AB. The patients with CHD achieved higher scores on the Paykel stress scale of life events, and they had the higher level of neurotic and psychotic tendencies, as well as the lower level of extroversion compared to the healthy participants. Multivariate logistic regression model identified chronic stress (odds ratio 1.018; 95% confidence interval 1.007−1.028 as an important predictor for the occurrence of coronary heart disease, when adjusted for age, gender, nourishment and blood pressure. On the other side, the lower risk for the occurrence of CHD was observed among the participants who had the higher level of extroversion (odds ratio 0.859; 95% confidence interval 0.636−0.902. Conclusion. Chronic stress and introversion can be considered important risk factors for

  17. Management of Hypertension among Patients with Coronary Heart Disease

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Full Text Available Evidence suggests that coronary heart disease (CHD is the most common outcome of hypertension. Hypertension accelerates the development of atherosclerosis, and sustained elevation of blood pressure (BP can destabilize vascular lesions and precipitate acute coronary events. Hypertension can cause myocardial ischemia in the absence of CHD. These cardiovascular risks attributed to hypertension can be reduced by optimal BP control. Although several antihypertensive agents exist, the choice of agent and the appropriate target BP for patients with CHD remain controversial. In this succinct paper, we examine the evidence and the mechanisms for the linkage between hypertension and CHD and we discuss the treatment options and the goals of therapy that are consistent with the report of the seventh Joint National Committee on the Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC 7 and American Heart Association scientific statement. We anticipate changes in the recommendations of the forthcoming JNC 8.

    In patients with heart failure, coronary artery disease is the most common underlying heart disease, and is associated with increased mortality. However, estimating the presence or absence of coronary artery disease in patients with heart failure is sometimes difficult without coronary imaging. We reviewed 155 consecutive patients hospitalized with heart failure who underwent coronary angiography. The patients were divided into two groups: patients with (N = 59) and without (N = 96) coronary artery stenosis. The clinical characteristics and blood sampling data were compared between the two groups. The patients with coronary artery stenosis were older than those without. The prevalence of diabetes mellitus (DM), dyslipidemia and a history of revascularization was higher in the patients with coronary artery stenosis. Patients with coronary artery stenosis tended to have wall motion asynergy more frequently than those without. On the other hand, the prevalence of atrial fibrillation (AF) was lower in patients with coronary artery stenosis. The serum hemoglobin level and estimated glomerular filtration rate were lower in patients with coronary artery stenosis than in those without. In the multivariate analysis, DM (odds ratio 3.517, 95 % CI 1.601-7.727) was found to be the only the predictor of the presence of coronary artery stenosis in patients with heart failure. In conclusion, coronary imaging is strongly recommended for heart failure patients with DM to confirm the presence of coronary artery stenosis. PMID:25822806

    Shift and night work are among the most frequent occupational exposures. Such work schedules involve exposure to light-at-night, which may reduce normal nocturnal melatonin production, create circadian rhythm disruption, sleep deprivation and unhealthy lifestyle. There is strong experimental evidence that light-at-night and circadian disruption may increase the risk of cancer and coronary heart diseases. There is emerging, but limited epidemiologic evidence that night shift work may increase breast cancer and certain cardiovascular diseases. PMID:24629681

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 An operation on the beating heart was planned for a 60-year-old woman who applied to our clinic with aortic stenosis, three vessel coronary artery disease and poor left ventricular function. There are reports about beating heart valve surgery perfomed alone or combined with coronary artery bypass operations using continuous retrograde coronary sinus isothermic blood perfusion in patients with poor ventricle. We performed a coronary revascularization process for three-vessel disease on the pump beating heart and aortic valve replacement under cross-clamp using continuous retrograde coronary sinus isothermic blood perfusion in the same session. She was discharged on the sixth postoperative day after an uneventful recovery. She is well and active 24 months after the operation. Valve replacement using the retrograde coronary sinus isothermic blood perfusion technique due to its protective effect on the already borderline myocardial functions in patients with poor ventricles is a useful and clinically successful method.

    Diabetes impairs copper (Cu) regulation, causing elevated serum Cu and urinary Cu excretion in patients with established cardiovascular disease; it also causes cardiomyopathy and chronic cardiac impairment linked to defective Cu homeostasis in rats. However, the mechanisms that link impaired Cu regulation to cardiac dysfunction in diabetes are incompletely understood. Chronic treatment with triethylenetetramine (TETA), a Cu²⁺-selective chelator, improves cardiac function in diabetic patients, and in rats with heart disease; the latter displayed ∼3-fold elevations in free Cu²⁺ in the coronary effluent when TETA was infused into their coronary arteries. To further study the nature of defective cardiac Cu regulation in diabetes, we employed an isolated-perfused, working-heart model in which we infused micromolar doses of Cu²⁺ into the coronary arteries and measured acute effects on cardiac function in diabetic and non-diabetic-control rats. Infusion of CuCl₂ solutions caused acute dose-dependent cardiac dysfunction in normal hearts. Several measures of baseline cardiac function were impaired in diabetic hearts, and these defects were exacerbated by low-micromolar Cu²⁺ infusion. The response to infused Cu²⁺ was augmented in diabetic hearts, which became defective at lower infusion levels and underwent complete pump failure (cardiac output = 0 ml/min) more often (P hearts. To our knowledge, this is the first report describing the acute effects on cardiac function of pathophysiological elevations in coronary Cu²⁺. The effects of Cu²⁺ infusion occur within minutes in both control and diabetic hearts, which suggests that they are not due to remodelling. Heightened sensitivity to the acute effects of small elevations in Cu²⁺ could contribute substantively to impaired cardiac function in patients with diabetes and is thus identified as a new mechanism of heart disease.

    Arterial calcification is a well-recognized complication of advanced atherosclerosis. Chronic kidney disease (CKD) is characterized by significantly more pronounced, disseminated and fast-progressing calcification of the vascular system, including the coronary arteries. New computed tomography-based imaging techniques allow for the noninvasive assessment and monitoring of calcification in different vascular sites. Coronary artery calcification (CAC) develops early in the course of CKD and is ...

    Full Text Available The incidence and prevalence of congestive heart failure are actually increasing worldwide, especially in Western countries. In Europe and the United States, congestive heart failure represents a disabling clinical disease, accountable for increased hospitalization and health care costs. European guidelines have underlined the importance of pharmacological treatment to improve both patients’ outcomes and quality of life. The latest clinical trials to evaluate ivabradine’s efficacy have underlined its usefulness as a stand-alone medication and in combination with conventional congestive heart failure therapy, including in chronic kidney disease patients.

    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.

    Coronary perforation (CP) is a life-threatening complication that can occur during percutaneous coronary intervention (PCI). Little is known, however, about the incidence and clinical outcome of CP. We sought to investigate the occurrence of CP and its determinants and risk profile in a large-scale, prospective registry. From 2005 to 2008, unselected patients (n = 42,068) from 175 centers in 33 countries who underwent a PCI procedure were prospectively enrolled in the PCI registry of the Euro Heart Survey program. For the present analysis, patients experiencing CP during PCI (n = 124, 0.3%) were compared with those who underwent PCI without CP. Patients with CP were older, more often women, had more severe coronary disease, and underwent more complex types of coronary intervention. Independent factors associated with CP were the use of rotablation, intravascular ultrasound-guided PCI, bypass PCI, a totally occluded vessel, a type C lesion, peripheral arterial disease, and body mass index patients developed cardiac tamponade. In a small minority (3.3%), emergency bypass surgery had to be performed. The inhospital death rate was markedly elevated in patients with CP (7.3% vs 1.5%, p odds ratio 5.21, 95% confidence interval 2.34 to 11.60). In conclusion, in this real world, all-comers registry, the incidence of CP was low, occurred more often in patients who underwent more complex coronary interventions, and was associated with a fivefold higher hospital mortality.

Independent factors associated with CP were the use of rotablation, intravascular ultrasound-guided PCI, bypass PCI, a totally occluded vessel, a type C lesion, peripheral arterial disease, and body mass index <25. More than 10% of the patients developed cardiac tamponade. In a small minority (3.3%), emergency bypass surgery had to be performed. The inhospital death rate was markedly elevated in patients with CP (7.3% vs 1.5%, p <0.001). After adjustment for the EuroHeart score, CP remained a strong predictor of hospital mortality (odds ratio 5.21, 95% confidence interval 2.34 to 11.60). In conclusion, in this real world, all-comers registry, the incidence of CP was low, occurred more often in patients who underwent more complex coronary interventions, and was associated with a fivefold higher hospital mortality.

  19. Direct effects of smoking on the heart: silent ischemic disturbances of coronary flow

    International Nuclear Information System (INIS)

    Cigarette smoking is strongly associated with ischemic heart disease and acute coronary events. The effect of smoking a single cigarette on regional myocardial perfusion was studied in 13 chronic smokers with typical stable angina pectoris using positron emission tomography and rubidium-82 (82Rb). Findings were compared with the effects of physical exercise. After exercise, 8 patients (61%) had angina, ST depression and abnormal regional myocardial perfusion. Uptake of 82Rb increased from 49 +/- 8 to 60 +/- 7 in remote myocardium, but decreased from 46 +/- 3 to 37 +/- 5 in an ischemic area. The remaining 5 patients (39%) had homogeneous increases in 82Rb uptake without angina or ST depression. After smoking, 6 of the 8 patients with positive exercise test responses had a decrease in 82Rb uptake, from 47 +/- 3 to 35 +/- 6 in the same segment of myocardium affected during exercise. However, in contrast to exercise, the events during smoking were largely silent. The absolute decreases in regional 82Rb uptake after smoking occurred at significantly lower levels of myocardial oxygen demand than after exercise. This suggests that an impairment of coronary blood supply is responsible. Thus, in smokers with coronary artery disease, each cigarette can cause profound silent disturbances of regional myocardial perfusion that are likely to occur frequently during daily life. Such repeated insults may represent an important mechanism linking smoking with coronary events

    Treatment of patients with ischemic heart disease relies on evidence-based medications such as beta-blockers, angiotensin-converting enzyme inhibitors or angiotensin-receptor blockers, aspirin and statins, which are considered cornerstones to control symptoms, improve quality of life, reduce future events, and prolong survival. In spite of the clear benefits of therapy, previous studies have shown differences between the large randomized populations and the "real world" about long-term treatment in terms of efficacy, tolerability, costs, side effects and drug interactions. Moreover, a different awareness of the patient's compliance has been highlighted in relation to the setting (hospital, family doctor, etc.). The analysis and assessment of the prescription and efficacy of therapy for secondary prevention of coronary artery disease represent one of the most important challenges for the healthcare system, because reliable data are necessary to verify usefulness and results of therapy, prescribed at discharge after an acute coronary syndrome and/or coronary artery bypass graft, but above all the actual application of treatments should be pursued in every clinical setting. The Cardiology School of the Trieste University has constituted a working group of cardiology students that during the year 2009 will enroll and follow for 1 year all patients with coronary artery disease discharged from the Cardiovascular Department and Emergency Unit of the University Hospital of Trieste to assess: (1) if evidence-based medicine for secondary prevention of coronary artery disease is applied in the Trieste area; (2) adherence to prescribed treatment; (3) factors that are associated with non-adherence and consequences of non-adherence.

  6. Effect of Heart Rate and Coronary Calcification on the Diagnostic Accuracy of the Dual-Source CT Coronary Angiography in Patients with Suspected Coronary Artery Disease

    International Nuclear Information System (INIS)

    To evaluate the diagnostic accuracy of a dual-source computed tomography (DSCT) coronary angiography, with a particular focus on the effect of heart rate and calcifications. One hundred and nine patients with suspected coronary disease were divided into 2 groups according to a mean heart rate ( 400). 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

    Full Text Available Objective — studying dyssynchrony characteristics and evaluation correction effectiveness in patients with chronic heart failure (CHF of ischemic origin.Materials and methods. The study included 125 patients with chronic heart failure of ischemic etiology, 28 of them — with coronary heart disease (CHD who had undergone aorto-and / or mammarokoronary bypass and / or percutaneous coronary intervention, 42 — with coronary artery disease and postinfarction cardiosclerosis, 32 — with arrhythmic variant of coronary artery disease, 23 — with stable angina without evidence of arrhythmia. Among included patients, biventricular pacemakers were implanted for 17 patients. All patients underwent echocardiography with determination of the parameters of dyssynchrony.Results and conclusion. Among patients with CHF ischemic symptoms dyssynchrony was diagnosed in 36 (28.8 % cases. Statistically significant association between patients with cardiac arrhythmias and dyssynchrony was determined. At the same time the incidence of dyssynchrony was not associated with various forms of ischemic heart disease, and did not depend on the anamnesis of cardiac surgery. Dependence of the frequency of occurrence of dyssynchrony on the severity of CHF was revealed. Patients selected for implantation of biventricular pacemakers, especially in view of echocardiographic signs of dyssynchrony had significant improvement after providing cardiac resynchronization therapy. Effect of the treatment does not depend on the atrial fibrillation rhythm presence.

    Coronary artery disease is the leading cause of death worldwide. Many trials to date have investigated the diagnostic accuracy of coronary computed tomography angiography (CCTA) when compared to the gold standard diagnostic test, invasive coronary angiography. However, whether the use of a non-invasive anatomical test, such as CCTA, can translate into improved patient risk stratification, management and outcome has yet to be established. The Scottish COmputed Tomography of the HEART (SCOT-HEART) trial sought to address these questions and determined whether CCTA, when used in addition to standard care, could aid the diagnosis, further investigation and treatment of patients referred to the cardiology clinic with suspected angina due to coronary heart disease. In this trial, CCTA clarified the diagnosis of angina due to coronary heart disease in a quarter of patients and this led to major alterations in treatment and management that appeared to reduce the risk of subsequent coronary heart disease death or non-fatal myocardial infarction. The SCOT-Heart trial has established that CCTA is a valuable diagnostic test in patients with suspected angina pectoris due to coronary heart disease and leads to greater clarity, more focused appropriate treatments and better coronary heart disease outcomes.

There were no operation-related death;one died of respiratory failure 14 days after operation while staying in hospital; there were more respiratory complications in the conventional coronary artery bypass grafting group (CCABG) than in the OPCABG group; and the PaO2/FiO2 in the CCABG group was higher than that in the OPCABG group during operation because of CPB, but lower than that in the OPCABG group 6-12 hours after operation. OPCABG seemed more suitable than CCABG for coronary artery disease patients with chronic obstructive pulmonary disease due to less damage to their oxygen-exchange capability and the fewer respiratory complications.

As a class, BAS are known to reduce cholesterol and glucose levels, and to reduce atherosclerotic coronary heart disease (CHD risk as monotherapy, and in combination with other lipid-altering drug therapies. Colesevelam HCl has specifically been shown to reduce total and low-density lipoprotein (LDL cholesterol levels, and has been approved as a cholesterol-lowering drug since year 2000. It has also been shown to reduce glucose levels. This discussion reviews mechanisms by which BAS lower cholesterol, and potential mechanisms by which BAS lower glucose levels in patients with type 2 diabetes mellitus. Finally this paper specifically reviews colesevelam HCl’s pharmacology, lipid and glucose efficacy, safety/tolerability, and clinical use.Keywords: cholesterol, colesevelam HCl, coronary heart disease, diabetes mellitus, glucose, lipids

    2014-09-01

    The efficacy of statins in reducing morbidity and mortality in patients with documented coronary artery disease is unquestionable. However, in chronic heart failure (CHF), evidence regarding the beneficial effects of statin therapy remains contradictory. Although numerous retrospective studies have demonstrated improved prognosis in CHF patients treated with statins, two randomized trials, GISSI-HF and CORONA, have not confirmed the benefit of rosuvastatin in this group of patients. The benefits of using statins in CHF probably result mostly from their pleiotropic action, including the improvement of endothelial function, the inhibition of neurohormonal activation, and the reduction of proinflammatory activation. On the other hand, it has been recognized that low cholesterol is associated with worse morbidity and mortality in patients with CHF. It appears that it is necessary to conduct further randomized clinical trials using different kinds of statins in different populations of patients with CHF. PMID:26336439

  20. Can patients with coronary heart disease go to high altitude?

    Dehnert, Christoph; Bärtsch, Peter

    2010-01-01

    Tourism to high altitude is very popular and includes elderly people with both manifest and subclinical coronary heart disease (CHD). Thus, risk assessment regarding high altitude exposure of patients with CHD is of increasing interest, and individual recommendations are expected despite the lack of sufficient scientific evidence. The major factor increasing cardiac stress is hypoxia. At rest and for a given external workload, myocardial oxygen demand is increased at altitude, particularly in nonacclimatized individuals, and there is some evidence that blood-flow reserve is reduced in atherosclerotic coronary arteries even in the absence of severe stenosis. Despite a possible imbalance between oxygen demand and oxygen delivery, studies on selected patients have shown that exposure and exercise at altitudes of 3000 to 3500 m is generally safe for patients with stable CHD and sufficient work capacity. During the first days at altitude, patients with stable angina may develop symptoms of myocardial ischemia at slightly lower heart rate x  blood-pressure products. Adverse cardiac events, however, such as unstable angina coronary syndromes, do not occur more frequently compared with sea level except for those who are unaccustomed to exercise. Therefore, training should start before going to altitude, and the altitude-related decrease in exercise capacity should be considered. Travel to 3500 m should be avoided unless patients have stable disease, preserved left ventricular function without residual capacity, and above-normal exercise capacity. CHD patients should avoid travel to elevations above 4500 m owing to severe hypoxia at these altitudes. The risk assessment of CHD patients at altitude should always consider a possible absence of medical support and that cardiovascular events may turn into disaster. PMID:20919884

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

    In patients with diabetes mellitus, cardiovascular disease is the principal cause of mortality and chest pain is the most frequent symptom in patients with stable and acute coronary artery disease. However, there is little knowledge concerning the pervasiveness of uncommon presentations in diabetics. The symptomatology of acute coronary syndrome, which comprises both pain and non-pain symptoms, may be affected by traditional risk factors such as age, gender, smoking, hypertension, diabetes, and dyslipidemia. Such atypical symptoms may range from silent myocardial ischemia to a wide spectrum of non-chest pain symptoms. Worldwide, few studies have highlighted this under-investigated subject, and this aspect of ischemic heart disease has also been under-evaluated in the major clinical trials. The results of these studies are highly diverse which makes definitive conclusions regarding the spectrum of atypical presentation of acute and even stable chronic coronay artery disease difficult to confirm. This may have a significant impact on the morbidity and mortality of coronary artery disease in diabetics. In this up-to-date review we will try to analyze the most recent studies on the atypical presentations in both acute and chronic ischemic heart disease which may give some emphasis to this under-investigated topic.

    The occurrence of heart failure during the whole pre-discharge course of coronary revascularization, as far as its influence on subsequent prognosis, is poorly understood. The present study examined the effect of transient heart failure (THF) developing in the acute and rehabilitative phase on survival after coronary artery bypass graft surgery (CABG) and percutaneous coronary intervention (PCI). Patients in the Italian survey on cardiac rehabilitation and secondary prevention after cardiac revascularization (ICAROS) were analyzed for THF, the latter being defined either as signs and symptoms consistent with decompensation or cardiogenic shock. ICAROS was a prospective, multicenter registry of 1,262 consecutive patients discharged from 62 cardiac rehabilitation (CR) facilities, providing data on risk factors, lifestyle habits, drug treatments, and major cardiovascular events (MACE) during a 1-year follow-up. Records were linked to the official website of the Italian Association of Cardiovascular Prevention and Rehabilitation (GICR-IACPR). The overall prevalence of pre-discharge THF was 7.6%, with 69.8% of cases in acute wards, 22.9% during CR, and 7.3% in both settings. THF affected more frequently patients with chronic cardiac condition (42.7 vs. 30.6%; p After discharge, THF patients showed good maintenance rates of RAAS modulators (90.6%) and beta-blockers (83.3%), while statin therapy significantly decreased from 81.3 to 64.6% (p after coronary revascularization had increased post-discharge mortality and cardiovascular events. Hemodynamic instability, rather than recurrent myocardial ischemia, seems to be linked with worse prognosis. PMID:24146110

    Full Text Available The resistance exercise is an important part of all rehabilitation programs in patients with chronic heart failure. Among several kinds of resistance exercises, the one mainly applied is isotonic exercise, whereas, in the contrary, isometric is not heavily used although it affects the daily lives of patients who, trying to look after themselves (moving, walking, lifting objects, twitch in an isometric way their peripheral muscles due to reduced cardiovascular endurance. Purpose: The purpose of the present review was to present the data available so far for isometric exercise in cardiovascular patients and to examine the importance of applying this kind of exercise in rehabilitation programs in the context of, firstly, evaluation, and secondly therapeutic intervention. Material - Methods: The methodology followed included searching inquiries and reviews from international databases (Pubmed, Medline, Scopus on the effects of isometric exercise in patients with chronic heart failure. The progress and development of the studies are of particular importance to this work and, to this end, the literature refers to the entire range of time in the last three decades, from 1985 to 2012 according the key words noted. Results: In rehabilitation programs for patients with chronic heart failure, resistance exercise if applied in an isotonic way helps improve hemodynamic and functional parameters. In contrast, resistance exercise applied in an isometric way requires further investigation because most findings are related to hemodynamic disturbances. The data which is encouraging for isometric exercise programs are few and, therefore, it cannot be directly recommended as a proper way to exercise. Conclusions: Isometric exercise has an important place in the evaluation of patients with chronic heart failure, and limits should be "placed" in its application as a therapeutic tool to prevent complications.

    Full Text Available Despite the improvements in diagnostic tools and medical applications, cardiovascular diseases (CVD, especially coronary artery disease (CAD, remain the most common cause of morbidity and mortality in patients with chronic kidney disease (CKD. The main factors for the heightened risk in this population, beside advanced age and a high proportion of diabetes and hypertension, are malnutrition, chronic inflammation, accelerated atherosclerosis, endothelial dysfunction, coronary artery calcification, left ventricular structural and functional abnormalities, and bone mineral disorders. Chronic kidney disease is now recognized as an independent risk factor for CAD. In community-based studies, decreased glomerular filtration rate (GFR and proteinuria were both found to be independently associated with CAD. This paper will discuss classical and recent epidemiologic, pathophysiologic, and clinical aspects of CAD in CKD patients.

    Chronic oral anticoagulant treatment is obligatory in patients (class I) with mechanical heart valves and in patients with atrial fibrillation with CHADS2 score >1. When these patients undergo percutaneous coronary intervention with placement of a stent, there is also an indication for treatment with aspirin and clopidogrel. Unfortunately, triple therapy is known to increase the bleeding risk. For this group of patients, the bottom line is to find the ideal therapy in patients with indications for both chronic anticoagulation therapy and percutaneous intervention to prevent thromboembolic complications such as stent thrombosis without increasing the risk of bleeding.

    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.

    Full Text Available Background: It has been suggested that the autonomic system function and the metabolic syndrome can significantly affect patients' survival. The aim of the current study was to investigate the impact of the cardiac rehabilitation program on the autonomic system balance in patients with coronary artery disease.Methods: Patients with a previous diagnosis of coronary artery disease who were referred to the Cardiovascular Rehabilitation Center of Afshar Hospital (Yazd, Iran between March and November 2011 were enrolled. All the patients participated in rehabilitation sessions 3 times a week for 12 weeks. Heart rate recovery (HRR was measured as an indicator of the autonomic system balance. In order to calculate HRR, the maximum heart rate during the exercise test was recorded. At the end of the exercise test, the patients were asked to sit down without having a cooldown period and their heart rate was recorded again after 1 minute. The difference between these 2 measurements was considered as HRR.Results: A total of 108 patients, including 86 (79.6% men and 22 (20.4% women, completed the rehabilitation course. The mean age of the study participants was 58.25 ± 9.83 years. A statistically significant improvement was observed in HRR (p value = 0.040. Significant declines were also observed in the patients' waist circumference (p value < 0.001 and systolic and diastolic blood pressures (p value = 0.018 and 0.003, respectively. A decreasing trend was observed in the patients' body mass index, but it failed to reach statistical significance (p value = 0.063. No statistically meaningful changes were noted in fasting blood glucose (p value = 0.171, high-density lipoprotein (p value = 0.070, or triglyceride concentrations (p value = 0.149. Conclusion: The cardiac rehabilitation program may help to improve HRR and several components of the metabolic syndrome in patients with coronary heart disease.

    Cardiovascular diseases, especially coronary heart disease (CHD), are epidemic in India. The Registrar General of India reported that CHD led to 17% of total deaths and 26% of adult deaths in 2001-2003, which increased to 23% of total and 32% of adult deaths in 2010-2013. The World Health Organization (WHO) and Global Burden of Disease Study also have highlighted increasing trends in years of life lost (YLLs) and disability-adjusted life years (DALYs) from CHD in India. In India, studies have reported increasing CHD prevalence over the last 60 years, from 1% to 9%-10% in urban populations and dyslipidemias, smoking, diabetes, hypertension, abdominal obesity, psychosocial stress, unhealthy diet, and physical inactivity. Suitable preventive strategies are required to combat this epidemic. PMID:27372534

    Blood flow structure was studied by PC integrated video camera with following slide by slide analysis. Volumetric blood flow velocity was supporting on constant level (1 ml/h). Silicone tube of diameter comparable with coronary arteries diameter was used as vessel model. Cell-cell interactions were studied under glucose and anticoagulants influence. Increased adhesiveness of blood cells to tube walls was revealed in patient with coronary heart disease (CHD) compare to practically healthy persons (PHP). In patients with stable angina pectoris of high functional class and patients with AMI shear stress resistant erythrocyte aggregates were predominating in blood flow structure up to microclots formation. Clotting and erythrocytes aggregation increase as response to glucose solution injection, sharply defined in patients with CHD. Heparin injection (10 000 ED) increased linear blood flow velocity both in patients with CHD and PHP. After compare our results with other author's data we can consider that method used in our study is sensible enough to investigate blood flow structure violations in patients with CHD and PHP. Several differences of cell-cell interaction in flow under glucose and anticoagulant influence were found out in patients with CHD and PHP.

    Objective To describe the association between apolipoprotein E alleles, dyslipidemia, and coronary heart disease (CHD). Methods Using polymerase chain reaction (PCR) the restriction fragment length polymorphism (RFLP), we studied the apolipoprotein E genotypes in 142 patients with coronary artery disease (CAD) and 131 age-matched healthy subjects, as well as the association between apolipoprotein, plasma lipids, and CHD. Results Compared with the E3 allele, the E4 allele was associated with elevated total cholesterol (TC) values (average increase about 0.32-0.58 mmol/L), low-density lipoprotein cholesterol (LDL-C) values, and apolipoprotein B (APOB). The E2 allele has opposite effects (average decrease about 0.34-0.61 mmol/L at TC). Both in cases and controls, the allelic frequency of E3/3 was highest, reaching 67.8% of whole volume, hemozygote of apo E3 was moderate, and homozygote E4/4 was low, E2/2 and E4/2 were rare. The frequencies of E3/4 and E4/4 were significantly higher in patients with CAD compared with controls (P<0.001).Conclusion Apolipoprotein E alleles are important genetic markers for dyslipidemia and CHD.The carrier of E4 gene was the risk factor of CHD.

    Chronic heart failure (CHF) is the leading cause of hospitalization for those over the age of 65 and represents a significant clinical and economic burden. About half of hospital re-admissions are related to co-morbidities, polypharmacy and disabilities associated with CHF. Moreover, CHF also has an enormous cost in terms of poor prognosis with an average one year mortality of 33%–35%. While more than half of patients with CHF are over 75 years, most clinical trials have included younger patients with a mean age of 61 years. Inadequate data makes treatment decisions challenging for the providers. Older CHF patients are more often female, have less cardiovascular diseases and associated risk factors, but higher rates of non-cardiovascular conditions and diastolic dysfunction. The prevalence of CHF with reduced ejection fraction, ischemic heart disease, and its risk factors declines with age, whereas the prevalence of non-cardiac co-morbidities, such as chronic renal failure, dementia, anemia and malignancy increases with age. Diabetes and hypertension are among the strongest risk factors as predictors of CHF particularly among women with coronary heart disease. This review paper will focus on the specific consideration for CHF assessment in the older population. Management strategies will be reviewed, including non-pharmacologic, pharmacologic, quality care indicators, quality improvement in care transition and lastly, end-of-life issues. Palliative care should be an integral part of an interdiscipli-nary team approach for a comprehensive care plan over the whole disease trajectory. In addition, frailty contributes valuable prognostic in-sight incremental to existing risk models and assists clinicians in defining optimal care pathways for their patients.

    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.

    It is the aim of this manuscript to take into account the peculiarities and specific characteristics of elderly patients with chronic ischaemic heart disease from a multidisciplinary perspective, with the participation of the Spanish Society of Cardiology (sections of Geriatric Cardiology and Ischaemic Heart Disease/Acute Cardiovascular Care), the Spanish Society of Internal Medicine, the Spanish Society of Primary Care Physicians and the Spanish Society of Geriatrics and Gerontology. This consensus document shows that in order to adequately address these elderly patients a comprehensive assessment is needed, which includes comorbidity, frailty, functional status, polypharmacy and drug interactions. We conclude that in most patients medical treatment is the best option and that this treatment must take into account the above factors and the biological changes associated with aging.

    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.

    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, P<0.001). In conclusion, the decrease in HR with ivabradine was associated with an increase in central systolic pressure, which may have antagonized possible benefits of HR lowering in coronary artery disease patients.

    Cardiovascular disease is the leading cause of morbidity and mortality in the world. In recent years, there has been an increasing interest both in basic and clinical research regarding the field of cell therapy for coronary heart disease (CHD). Several preclinical models of CHD have suggested that regenerative properties of stem and progenitor cells might help restoring myocardial functions in the event of cardiac diseases.

    Cardiovascular disease is the leading cause of morbidity and mortality in the world. In recent years, there has been an increasing interest both in basic and clinical research regarding the field of cell therapy for coronary heart disease (CHD). Several preclinical models of CHD have suggested that regenerative properties of stem and progenitor cells might help restoring myocardial functions in the event of cardiac diseases. Here, we summarize different types of stem/progenitor cells that have been tested in experimental and clinical settings of cardiac regeneration, from embryonic stem cells to induced pluripotent stem cells. Then, we provide a comprehensive description of the most common cell delivery strategies with their major pros and cons and underline the potential of tissue engineering and injectable matrices to address the crucial issue of restoring the three-dimensional structure of the injured myocardial region.

    It has been consistently observed that patients with renal dysfunction have more premature, severe, complicated, and fatal cardiovascular disease than age- and sex-matched individuals with normal renal function. There have been 4 major explanations for this finding: (1) positive confounding by third variables associated with chronic kidney disease (CKD), including diabetes mellitus and hypertension; (2) therapeutic nihilism or lesser use of beneficial therapies in CKD; (3) greater toxicities of therapies, such as bleeding from anticoagulants or contrast-induced kidney injury; (4) biological factors which result directly from CKD that work to promote and accelerate cardiovascular disease. In this paper, we focus on the issue of treatment disparities or therapeutic nihilism and its contribution to poor outcomes in the setting of acute coronary syndromes and acutely decompensated heart failure. This issue is important because if we can overcome barriers to the utilization of beneficial treatments, then clinical outcomes should improve over time. PMID:21625092

    To evaluate the diagnostic accuracy of a dual-source computed tomography (DSCT) coronary angiography, with a particular focus on the effect of heart rate and calcifications. One hundred and nine patients with suspected coronary disease were divided into 2 groups according to a mean heart rate (< 70 bpm and {>=} 70 bpm) and into 3 groups according to the mean Agatston calcium scores ({<=} 100, 101-400, and > 400). 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

    Full Text Available Abstract Background Chest pain raises concern for the possibility of coronary heart disease. Scoring methods have been developed to identify coronary heart disease in emergency settings, but not in primary care. Methods Data were collected from a multicenter Swiss clinical cohort study including 672 consecutive patients with chest pain, who had visited one of 59 family practitioners' offices. Using delayed diagnosis we derived a prediction rule to rule out coronary heart disease by means of a logistic regression model. Known cardiovascular risk factors, pain characteristics, and physical signs associated with coronary heart disease were explored to develop a clinical score. Patients diagnosed with angina or acute myocardial infarction within the year following their initial visit comprised the coronary heart disease group. Results The coronary heart disease score was derived from eight variables: age, gender, duration of chest pain from 1 to 60 minutes, substernal chest pain location, pain increasing with exertion, absence of tenderness point at palpation, cardiovascular risks factors, and personal history of cardiovascular disease. Area under the receiver operating characteristics curve was of 0.95 with a 95% confidence interval of 0.92; 0.97. From this score, 413 patients were considered as low risk for values of percentile 5 of the coronary heart disease patients. Internal validity was confirmed by bootstrapping. External validation using data from a German cohort (Marburg, n = 774 revealed a receiver operating characteristics curve of 0.75 (95% confidence interval, 0.72; 0.81 with a sensitivity of 85.6% and a specificity of 47.2%. Conclusions This score, based only on history and physical examination, is a complementary tool for ruling out coronary heart disease in primary care patients complaining of chest pain.

    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.

    The diagnosis of coronary heart disease increasingly depends on referring and combining the information from a variety of imaging techniques. The fusion imaging of the anatomy and function provides a convenient 'one stop' examination which improves the existing imaging examination process. The development of the image fusion techniques, such as SPECT/coronary angiography, SPECT/CT, especially PET/CT, has shown a larger value in the diagnosis, risk stratification, clinical treatment guidance and efficacy prognosis of coronary heart disease than a single imaging examination, while the more complete data of the image and the quantitative analysis provide more useful information for the clinic.

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

    AIM To determine the prevalence of depression and its risk factors among patients with coronary heart disease (CHD) treated in German primary care practices. METHODS Longitudinal data from nationwide general practices in Germany (n = 1072) were analyzed. Individuals initially diagnosed with CHD (2009-2013) were identified, and 59992 patients were included and matched (1:1) to 59992 controls. The primary outcome measure was an initial diagnosis of depression within five years after the index date among patients with and without CHD. Cox proportional hazards models were used to adjust for confounders. RESULTS Mean age was equal to 68.0 years (SD = 11.3). A total of 55.9% of patients were men. After a five-year follow-up, 21.8% of the CHD group and 14.2% of the control group were diagnosed with depression (P risk factor for developing depression (HR = 1.54, 95%CI: 1.49-1.59, P risk of developing depression. Interestingly, older patients and women were also more likely to be diagnosed with depression compared with younger patients and men, respectively. CONCLUSION The risk of depression is significantly increased among patients with CHD compared with patients without CHD treated in primary care practices in Germany. CHD patients should be routinely screened for depression to ensure improved treatment and management.

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.

    Full Text Available Being a common syndrome chronic heart failure (CHF results in high mortality among cardiosurgical patients and requires very high expenditures for the treatment. All over the world the number of patients with CHF syndrome is about 22 millions. Heart failure is difficult to treat because of high level of hospitalization due to decompensation. Care aimed at constant home observation of patients could have been more efficient and not only symptomatic and as a response to complications induced. There are methods controlling CHF patients at home. These methods vary from increase of self-care and telephone support to telemonitoring and remote monitoring of implantable devices. Self-care includes such components as maintenance of drug intake, keeping to a diet, physical exercises and active control over edemas. Telephone calls are also a source of monitoring and treatment of heart failure at home. Meta-analysis of programs for structured phone support showed that telephone support could reduce the level of readmission of HF patients approximately by 25%. Telemonitoring implies transmission of such physiological data as blood pressure, body weight, electrocardiographic signals or oxygen saturation using phone lines, broadband and satellite or wireless networks. Having cardiac pacemakers, implantable cardioverter defibrillators and cardiac resynchronization therapy devices that are placed in HF patients, it is possible to use their opportunities for the further evaluation of the patient. Some regularly controlled parameters can show the clinical state of the patient and predict the following heart failure. For example, atrial fibrillation, decrease of cardiac rhythm variability and decrease of the level of the patient`s activity (according to integrated accelerometer can predict clinical decompensation. Also, implantable hemodynamic monitors for immediate pressure measuring in the left atrium, sensor system of pressure measuring in the right atrium are

    Although the management of chronic heart failure (CHF) has made enormous progress over the past decades,CHF is still a tremendous medical and societal burden.Metabolic remodeling might play a crucial role in the pathophysiology of CHF.The characteristics and mechanisms of metabolic remodeling remained unclear,and the main hypothesis might include the changes in the availability of metabolic substrate and the decline of metabolic capability.In the early phases of the disease,metabolism shifts toward carbohydrate utilization from fatty acids (FAs) oxidation.Along with the progress of the disease,the increasing level of the hyperadrenergic state and insulin resistance cause the changes that shift back to a greater FA uptake and oxidation.In addition,a growing body of experimental and clinical evidence suggests that the improvement in the metabolic capability is likely to be more significant than the selection of the substrate.

  13. Whole heart coronary imaging with flexible acquisition window and trigger delay.

    Directory of Open Access Journals (Sweden)

    Keigo Kawaji

    Full Text Available 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

    Background One of the characteristics of atherosclerosis is a change in the content of extracellular matrix in the arterial wall. Gelatinase B, a member of the family of matrix metalloproteinase, can regulate extracellular matrix metabolismand play a role in the pathogenesis of atherosclerosis, coronary heart disease (CHD) and myocardial infarction (MI). Gelatinase B is polymorphic due to a C to T change at the position -1562 bp in the promoter region.Its relationship with gene product concentration in serum and its role in mediating the risk of CHD and MI in Germans is still unknown. Methods We enrolled 102 controls and 322 patients with angiographically documented CHD,including a sub-group of 173 patients with acute or chronic MI and 80 patients with acute coronary syndrome (ACS).All patients and controls were Germans and genotyped by polymerase chain reaction and digestion with SphI. Results We found that several classical risk factors for CHD and MI, including hypercholesterolemia and cigarette smoking,were significantly increased in CHD and MI patients compared with controls. Serum levels of gelatinase B and tissue inhibitor of metalloproteinase-1 were increased in the peripheral blood of patients with acute coronary syndrome. No significant differences in genotype or allelic frequencies between CHD, MI and control subjects of either men or women were found. Our search for a possible association of the polymorphisms with CHD and MI by logistic regression analysis was also negative. The serum concentrations of gelatinase B showed no differences between genotypes. Conclusions Our data showed that gelatinase B might provide an index of plaque activity in ACS, but gelatinase B protein was not affected by genotypes. Also, the T variant of gelatinase B was not associated with CHD or MI in Germans. (J Geriatr Cardiol 2004;1(2):114-118.)

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

    The purpose of this study was to determine the cardiac phase having the highest coronary sharpness for low and high heart rate patients scanned with dual source CT (DSCT) and to compare coronary image sharpness over different cardiac phases. DSCT coronary CT scans for 30 low heart rate (70 bpm) patients were reconstructed into different cardiac phases, starting at 30% and increasing at 5% increments until 70%. A blinded observer graded image sharpness per coronary segment, from which sharpness scores were produced for the right (RCA), left main (LM), left anterior descending (LAD), and circumflex (Cx) coronary arteries. For each coronary artery, the phase with maximal image sharpness was identified with repeated measures analysis of variance. Comparison of coronary sharpness between low and high heart rate patients was made using generalized estimating equations. For low heart rates the highest sharpness scores for all four vessels (RCA, LM, LAD, and Cx) were at the 65 or 70% phase, which are end-diastolic cardiac phases. For high heart rates the highest sharpness scores were between the 35 and 45% phases, which are end-systolic phases. Low heart rate patients had higher coronary sharpness at most cardiac phases; however, patients with high heart rates had higher coronary sharpness in the 45% phase for all four vessels (P < 0.0001). Using DSCT scanning, optimal image sharpness is obtained in end-diastole at low heart rates and in end-systole in high heart rates. PMID:19669664

    Full Text Available 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: (inumber 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

    Bennett, Kathleen

    2009-01-01

    OBJECTIVE: Coronary heart disease (CHD) is associated with a large burden of disease in Ireland and is responsible for more than 6000 deaths annually. This study examined the cost-effectiveness of specific CHD treatments in Ireland. METHODS: Irish epidemiological data on patient numbers and median survival in specific groups, plus the uptake, effectiveness, and costs of specific interventions, all stratified by age and sex, were incorporated into a previously validated CHD mortality model, the IMPACT model. This model calculates the number of life-years gained (LYGs) by specific cardiology interventions to generate incremental cost-effectiveness ratios (ICERs) per LYG for each intervention. RESULTS: In 2000, medical and surgical treatments together prevented or postponed approximately 1885 CHD deaths in patients aged 25 to 84 years, and thus generated approximately 14,505 extra life-years (minimum 7270, maximum 22,475). In general, all the cardiac interventions investigated were highly cost-effective in the Irish setting. Aspirin, beta-blockers, ACE inhibitors, spironolactone, and warfarin for specific conditions were the most cost-effective interventions (< euro 3000\\/LYG), followed by the statins for secondary prevention (< euro 6500\\/LYG). Revascularization for chronic angina and primary angioplasty for myocardial infarction, although still cost-effective, had the highest ICER (between euro 12,000 and euro 20,000\\/LYG). CONCLUSIONS: Using a comprehensive standardized methodology, cost-effectiveness ratios in this study clearly favored simple medical treatments for myocardial infarction, secondary prevention, angina, and heart failure.

    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.

    2015-09-01

    Full Text Available Background: Chronic Heart Failure (CHF is highly prevalent and is associated with high morbidity and mortality rates. It has been well established that excessive intake of sodium chloride (salt induced hypertension in some populations. Although salt seems to induce cardiovascular diseases through elevation of blood pressure, it has also been indicated that salt can induce cardiovascular diseases independently from blood pressure elevation. Objectives: The present study aimed to evaluate the association between salt consumption and inflammation in CHF patients. Patients and Methods: This study was conducted on 86 patients between 18 and 65 years old who were diagnosed with New York Heart Association (NYHA functional class I and II heart failure. Salt intake was calculated by using 24 hour urine sodium excretion. Besides, the association between inflammation and daily salt intake was evaluated regarding C - reactive protein (CPR, High sensitive CRP (HsCPR, Erythrocyte Sedimentation Rate (ESR, and ferritin and fibrinogen levels using Pearson correlation analysis. Results: Our results showed a statistically significant difference between the low (n = 41 and high (n = 45 salt intake groups in terms of serum HsCRP levels (5.21 ± 2.62 vs. 6.36 ± 2.64 (P < 0.048. Additionally, a significant correlation was observed between the amount of salt consumption and HsCRP levels. In this study, daily salt consumption of the enrolled patients was 8.53 gram/day. The medications and even the blood pressures were similar in the two groups, but daily pill count, prevalence of hypertension, and coronary heart disease were higher in the high salt intake group; however, the differences were not statistically significant (P = 0.065. Also, no significant difference was observed between the groups concerning the inflammation markers, such as CRP, ESR, ferritin, and fibrinogen. Conclusions: Neurohumoral and inflammatory factors are thought to contribute to high mortality

    To discuss the etiology, pathogenesis, therapies and prescriptions of psycho-cardiological abnormality of patients with coronary heart disease. According to the advance in modern diagnosis and treatment, the authors believed that psycho-cardiological abnormality of patients with coronary heart disease is closely related with mental stresses, like anxiety, depression and insomnia. It is mostly caused by emotional injury and expressed in heart, liver, spleen and kidney. The pathogenesis is heart-liver hyperactivity, yin deficiency in heart and kidney, and insufficiency in heart and spleen. The full recognition of etiology and pathogenesis of psycho-cardiological abnormality of patients with coronary heart disease and the combined treatment of disease and syndromes are of great significance to reduce mental stress and other risk factors, prevent and treat coronary heart disease and improve prognosis.

    The lack of specific tests for the diagnosis of chronic Chlamydia pneumoniae infection has led to the use of enzyme immunoassay (EIA) instead of the gold standard, that is, microimmunofluorescence (MIF), in the measurement of C. pneumoniae antibodies. We assessed the predictive values of C. pneumoniae antibody levels and seroconversions measured by MIF and EIA for coronary events in the prospective Helsinki Heart Study. Sera from 239 cases with coronary events and 239 controls were available at the baseline and data from 210 cases and 211 controls before and after the event. The agreement between MIF and EIA antibody levels was best in high antibody titers. In conditional logistic regression analysis, only high IgA MIF titers (>/=40) at the baseline predicted future coronary events, and the participants with MIF seroconversion between consecutive sera had a higher (nonsignificant) risk for coronary events than the controls. The difference in the kinetics of EIA and MIF antibodies demonstrated that MIF should remain the gold standard. PMID:16757141

    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.

    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. PMID:26881144

    2016-01-01

    Summary Background Increased circulating plasma urate concentration is associated with an increased risk of coronary heart disease, but the extent of any causative effect of urate on risk of coronary heart disease is still unclear. In this study, we aimed to clarify any causal role of urate on coronary heart disease risk using Mendelian randomisation analysis. Methods We first did a fixed-effects meta-analysis of the observational association of plasma urate and risk of coronary heart disease. We then used a conventional Mendelian randomisation approach to investigate the causal relevance using a genetic instrument based on 31 urate-associated single nucleotide polymorphisms (SNPs). To account for potential pleiotropic associations of certain SNPs with risk factors other than urate, we additionally did both a multivariable Mendelian randomisation analysis, in which the genetic associations of SNPs with systolic and diastolic blood pressure, HDL cholesterol, and triglycerides were included as covariates, and an Egger Mendelian randomisation (MR-Egger) analysis to estimate a causal effect accounting for unmeasured pleiotropy. Findings In the meta-analysis of 17 prospective observational studies (166 486 individuals; 9784 coronary heart disease events) a 1 SD higher urate concentration was associated with an odds ratio (OR) for coronary heart disease of 1·07 (95% CI 1·04–1·10). The corresponding OR estimates from the conventional, multivariable adjusted, and Egger Mendelian randomisation analysis (58 studies; 198 598 individuals; 65 877 events) were 1·18 (95% CI 1·08–1·29), 1·10 (1·00–1·22), and 1·05 (0·92–1·20), respectively, per 1 SD increment in plasma urate. Interpretation Conventional and multivariate Mendelian randomisation analysis implicates a causal role for urate in the development of coronary heart disease, but these estimates might be inflated by hidden pleiotropy. Egger Mendelian randomisation analysis, which accounts for

    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.

    International Nuclear Information System (INIS)

    Objective: To evaluate robustness of coronary artery computed tomographic (CT) angiography with prospectively gated axial (PGA) CT technique at intermediate heart rate (65-75 beats per minute) using retrospectively gated helical (RGH) CT technique in 64-slice spiral CT. Methods: 63 consecutive patients with heart rates (HR) of 65 to 75 bpm, heart rate variability of below 5 bpm underwent CT angiography with RGH technique (tube voltage was 120 kV and tube current tailored to BMI). The 5% acquired data during each intermediate temporal window in the R-R interval were used to reconstruct images. The intermediate temporal window was 400 ms in the R-R interval at current mean HR, and the centre of the temporal window was 60%. All coronary artery segments were evaluated for image quality with 5-point scale. The mean image quality score and the percentage of assessable coronary artery segments were used to evaluate diagnostic value on the selected temporal window. Results: 822 coronary artery segments were depicted and were evaluated. The mean image quality score was 4.15±0.72. The percentage of assessable coronary artery segments was 97.76%. Conclusion: PCA coronary CT angiography with proper revise image acquisition phase and padding time could offer assessable image quality at intermediate HR. (authors)

    Full Text Available Background: The objective of this study was to evaluate the effect of a hospital-based cardiac rehabilitation program on heart rate recovery (HRR in patients who received percutaneous coronary intervention (PCI or coronary artery bypass grafting (CABG. Methods: Two hundred forty patients, who completed 24 sessions of a cardiac rehabilitation program (phase 2 after PCI (n=62 or CABG (n=178 at the rehabilitation department of Tehran Heart Center were included in the present study. Demographic and clinical characteristics and exercise capacity at baseline and at follow-up were compared between the two groups. The main outcome measurements were: Resting heart rate, peak heart rate, and HRR.Results: All the patients showed significant improvements in heart rate parameters from the baseline to the last sessions. The profile of atherosclerotic risk factors (except for diabetes mellitus was similar between the PCI and CABG subjects. After eight weeks of cardiac rehabilitation, HRR increased averagely about 17 and 21 bpm among the CABG and PCI patients, respectively (p=0.019. Conclusion: The results of the present study were indicative of an increase in HRR over 1 minute in patients irrespective of their initial revascularization modality (i.e. PCI or CABG after the completion of cardiac rehabilitation. Be that as it may, the PCI patients achieved greater improvement in HRR by comparison with the CABG patients.

    Coronary heart disease is dominant among heart diseases in the population, a problem to control. Heart diseases have been first place in the general mortality for the last 20 years. The trend show an annual increase without control. Atherosclerosis is responsible for at least for one fourth of all deaths in the country. The combined data of mortality and morbidity, from hospital discharges or the whole country, disclose that one out of three die of acute myocardial infarction (AMI). While only 8% of all deaths registered were admitted to a hospital. Most, 92% were never admitted to any hospital for some reason. The estimated annual incidence of AMI cases is 140,000, on the basis of 3 cases surviving for each case death, accounted by the Death Certification System, which rounds 35,000. Standardized mortality rates of AMI in Mexico are greater than in USA o Canada creating a more concerned worry. The most probable explanation to that situation is lack of preventive care, which should also include the acute care and before reaching the hospital facilities. Running the same chances are hypertension crisis and strokes and diabetic complications. The appropriate care for critical situations might reduce significantly the cardiovascular mortality in the country, in a short and middle term. Prevention is not only for chronic conditions but for acute and critical situations. The programs of preventive care should also include cultural promotion and community awareness. The timely care is life and myocardium saving. The reinforcement of prior to hospital care reduces the delay for AMI adequate intervention. These activities agree quite well with the ongoing programs of CPR, organizing the surviving chain and the training programs for paramedical emergency technicians.

    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

    Aims To investigate the causal role of high-density lipoprotein cholesterol (HDL-C) and triglycerides in coronary heart disease (CHD) using multiple instrumental variables for Mendelian randomization. Methods and results We developed weighted allele scores based on single nucleotide polymorphisms (SNPs) with established associations with HDL-C, triglycerides, and low-density lipoprotein cholesterol (LDL-C). For each trait, we constructed two scores. The first was unrestricted, including all independent SNPs associated with the lipid trait identified from a prior meta-analysis (threshold P < 2 × 10−6); and the second a restricted score, filtered to remove any SNPs also associated with either of the other two lipid traits at P ≤ 0.01. Mendelian randomization meta-analyses were conducted in 17 studies including 62,199 participants and 12,099 CHD events. Both the unrestricted and restricted allele scores for LDL-C (42 and 19 SNPs, respectively) associated with CHD. For HDL-C, the unrestricted allele score (48 SNPs) was associated with CHD (OR: 0.53; 95% CI: 0.40, 0.70), per 1 mmol/L higher HDL-C, but neither the restricted allele score (19 SNPs; OR: 0.91; 95% CI: 0.42, 1.98) nor the unrestricted HDL-C allele score adjusted for triglycerides, LDL-C, or statin use (OR: 0.81; 95% CI: 0.44, 1.46) showed a robust association. For triglycerides, the unrestricted allele score (67 SNPs) and the restricted allele score (27 SNPs) were both associated with CHD (OR: 1.62; 95% CI: 1.24, 2.11 and 1.61; 95% CI: 1.00, 2.59, respectively) per 1-log unit increment. However, the unrestricted triglyceride score adjusted for HDL-C, LDL-C, and statin use gave an OR for CHD of 1.01 (95% CI: 0.59, 1.75). Conclusion The genetic findings support a causal effect of triglycerides on CHD risk, but a causal role for HDL-C, though possible, remains less certain. PMID:24474739

    1985-07-01

    Research to predict stress, organizational effectiveness, and potential for developing coronary heart disease (CHD) is presented based on two samples (n = 357 and n = 225). Results indicate that perceived stress is predicted by a combination of individual and job related characteristics. The data suggest that stress, in turn, affects individual and organizational health and effectiveness, by causing increases in cold/flu episodes, somatic symptoms, while decreasing job satisfaction. In addition, stress has an indirect effect on job performance and absenteeism. Models for predicting the ratio of total serum cholesterol divided by HDL cholesterol as an indicator of coronary heart disease potential are provided and a CHD screening model is proposed.

  4. Vasopressin and ischaemic heart disease: more than coronary vasoconstriction?

    OpenAIRE

    2009-01-01

    During advanced vasodilatory shock, arginine vasopressin (AVP) is increasingly used to restore blood pressure and thus to reduce catecholamine requirements. The AVP-related rise in mean arterial pressure is due to systemic vasoconstriction, which, depending on the infusion rate, may also reduce coronary blood flow despite an increased coronary perfusion pressure. In a murine model of myocardial ischaemia, Indrambarya and colleagues now report that a 3-day infusion of AVP decreased the left ve...

    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.

    Background 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.Methods 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.Results 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 common in

    Xueshuan Xinmaining tablet is a Chinese patent medicine for treating chest pain caused by blood stasis. It is widely used in clinical prevention and treatment of coronary heart disease. In order to understand the treatment effect of Xueshuan Xinmaining tablet in patients with coronary heart disease, we extracted electronic medical record data from 18 large hospitals nationwide. We matched the coronary artery disease patients with or without Xueshuan Xinmaining tablet treatment on gender, age, condition at admission and whether combined with cardiac insufficiency on a one to one ratio. After matching, both groups, patients using Xueshuan Xinmaining tablet (group A) and patients not using Xueshuan Xinmaining tablet (group B), ended up with 1,122 people. In order to evaluate the effectiveness of treatment, the endpoint of effective group was defined as "cure" and "better" while the endpoint of invalid group was defined as "invalid" and "death". Chi-square test showed a statistical significant difference (P coronary heart disease, with a higher efficiency in Xueshuan Xinmaining group. Classic logistic regression analysis showed no statistical significant difference between the two groups on treatment outcome efficiency. Generalized boosted models (GBM) and propensity score (PS) weighted Logistic regression were then applied to balance 45 variables between the two groups. The results showed a regression coefficient greater than 0 and a statistical significant difference (P coronary heart disease patients using Xueshuan Xinmaining tablet had a higher efficiency in clinical efficiency than the patients not using Xueshuan Xinmaining tablet. Since this study did not certainly eliminate all the possible confounders and patients from the hospitals included in this study were not yet well represent the overall situation of the source population, the study conclusion only provided drug use reference for clinical doctors for coronary heart disease.

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

  17. Whole-body MR vascular screening detects unsuspected concomitant vascular disease in coronary heart disease patients

    International Nuclear Information System (INIS)

    Coronary heart disease (CHD) patients often show atherosclerotic vascular disease in other vascular territories. We evaluated how often whole-body MR imaging detects concomitant arterial pathologies in CHD patients, and how often these pathologies were not known to the patients previously. Of 4,814 participants in the population-based Heinz Nixdorf Recall Study, 327 reported CHD (i.e., previous coronary bypass surgery, angioplasty); of those, 160 patients (mean age 66.4 years) were examined using MR of the brain, the heart (excluding the coronary arteries), and whole-body MR angiography. The prevalence of each vascular pathology was assessed, correlated to the others and compared to patients' histories. Of the 160 CHD patients, 16 (10%) showed MR signs of stroke, and 77 (48.1%) had a stenosis >50% in at least one extracerebral peripheral artery (other than the coronaries), including 28 (17.5%) with relevant renal artery stenoses, and 20 (12.5%) with relevant extracerebral internal carotid artery stenoses. False negative histories were reported in 12 of 81 cases with myocardial infarctions, and in 11 of 16 cases with cerebrovascular infarctions. This whole-body atherosclerosis MR screening program allows previously unknown concomitant vascular disease to be detected in coronary heart disease patients. Its prospective value should be assessed in further studies. (orig.)

    2001-01-01

    Objective: To explore the patterns of Syndrome Differentiation (SD) of coronary heart disease (CHD) patients in peri-operative stage of coronary artery bypass graft (CABG). Methods: One week after operation, thirty-seven CHD patients, who received CABG of internal mammary artery or great saphena vein under conventional general anesthesia with low or middle temperature extracorporeal circulation were differentiated as various syndromes, with the pre- or post-operational EKG, color Doppler echocardiography were done during and after operation. The hemodynamic parameters were monitored. Results: In the CHD patients, 64.9% were differentiated as Qi-Yin deficiency, 67.6% were complicated with phlegm syndrome and 62.2% with blood stasis, suggesting that Qi-deficiency, phlegm and stasis are the basic pathogenetic factors in patients with CABG. Moreover, the peri-operative syndrome was correlated with the condition of coronary artery lesion, heart and lung functions before operation, and the extracorporeal circulation time during the operation. Conclusion: TCM SD conducting in peri-operative stage might be useful in exploring the patterns of syndrome alteration which provided a basis for preventing peri-operative complications and elevating success rate of operation.

  20. Low-Dose Nonlinear Effects of Smoking on Coronary Heart Disease Risk

    Science.gov (United States)

    Cox, Louis Anthony (Tony)

    2012-01-01

    Some recent discussions of adverse human health effects of active and passive smoking have suggested that low levels of exposure are disproportionately dangerous, so that “The effects of even brief (minutes to hours) passive smoking are often nearly as large (averaging 80% to 90%) as chronic active smoking” (Barnoya and Glantz, 2005). Recent epidemiological evidence (Teo et al., 2006) suggests a more linear relation. This paper reexamines the empirical relation between self-reported low levels of active smoking and risk of coronary heart disease (CHD) in public-domain data from the National Health and Nutrition Examination Survey (NHANES). Consistent with biological evidence on J-shaped and U-shaped relations between smoking-associated risk factors and CHD risks, we find that low levels of active smoking do not appear to be associated with increased CHD risk. Several methodological challenges in epidemiology may explain how model-derived estimates can predict low-dose linear or concave dose-response estimates, even if the empirical (i.e., data-based) relation does not show a clear increased risk at the lowest doses.

    Diet is a key modifiable risk factor in the prevention and risk reduction of coronary heart disease (CHD). Results from the Seven Countries Study in the early 1970s spurred an interest in the role of single nutrients such as total fat in CHD risk. With accumulating evidence, we have moved away from a focus on total fat to the importance of considering the quality of fat. Recent meta-analyses of intervention studies confirm the beneficial effects of replacing saturated fat with polyunsaturated fatty acids on CHD risk. Scientific evidence for a detrimental role of trans fat intake from industrial sources on CHD risk has led to important policy changes including listing trans fatty acid content on the "Nutrition Facts" panel and banning the use of trans fatty acids in food service establishments in some cities. The effects of such policy changes on changes in CHD incidence are yet to be evaluated. There has been a surging interest in the protective effects of vitamin D in primary prevention. Yet, its associations with secondary events have been mixed and intervention studies are needed to clarify its role in CHD prevention. Epidemiological and clinical trial evidence surrounding the benefit of B vitamins and antioxidants such as carotenoids, vitamin E, and vitamin C, have been contradictory. While pharmacological supplementation of these vitamins in populations with existing CHD has been ineffective and, in some cases, even detrimental, data repeatedly show that consumption of a healthy dietary pattern has considerable cardioprotective effects for primary prevention. Results from these studies and the general ineffectiveness of nutrient-based interventions have shifted interest to the role of foods in CHD risk reduction. The strongest and most consistent protective associations are seen with fruit and vegetables, fish, and whole grains. Epidemiological and clinical trial data also show risk reduction with moderate alcohol consumption. In the past decade, there has

  7. 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

    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.

    Science.gov (United States)

    De Maria, Giovanni Luigi; Kassimis, George; Raina, Tushar; Banning, Adrian P

    2016-08-15

    Coronary sinus interventions (CSI) are a class of invasive techniques (surgical and percutaneous) originally proposed in the first half of the 20th century, aiming to treat ischaemic heart disease by acting on the venous coronary system. Three main classes of CSI have been proposed and tested: (1) retroperfusion technique, (2) retroinfusion technique and (3) coronary sinus occlusion techniques. They all share the principle that a controlled increased pressure within the coronary sinus may promote a retrograde perfusion of the ischaemic myocardium with consequent cardioprotection. Development of arterial treatments including coronary aortic bypass grafting and then percutaneous coronary intervention deflected interest from interventions on the coronary venous system. However, CSI may still have a possible niche role today in specific and selected clinical contexts in which existing therapies are insufficient. In this review paper, we aim to revise the rationale for CSI, describing the details and the evidence collected so far about these techniques and to provide insights about the main clinical scenarios in which these strategies may find a contemporary application in combination or as an alternative to existing approaches.

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.

    Erythrocytes and platelets phospholipid membranes fatty acid spectrum was detected in coronary heart disease and atrial fibrillation patients and in patients with coronary heart disease without atrial fibrillation. 87 patients were investigated. Significant decrease in the arachidonic acid relative content in coronary heart disease patients compared with healthy individuals was related. As well as a significant decrease in the arachidonic acid relative content in coronary heart disease and atrial fibrillation patients compared with coronary heart disease patients without atrial fibrillation was related too. These dates may indicate that decreasing relative content arachidonic acid can be possible pathogenetic link in the development of arrhythmias.

    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

    Heart disease remains the leading cause of death in the USA. Overall, heart disease accounts for about 1 in 4 deaths with coronary heart disease (CHD) being responsible for over 370,000 deaths per year. It has frequently and repeatedly been shown that some minority groups in the USA have higher rates of traditional CHD risk factors, different rates of treatment with revascularization procedures, and excess morbidity and mortality from CHD when compared to the non-Hispanic white population. Numerous investigations have been made into the causes of these disparities. This review aims to highlight the recent literature which examines CHD in ethnic minorities and future directions in research and care.

    The frequency of coronary heart disease (CHD) is increasing among HIV seropositive persons. This phenomenon may be related to HIV disease itself, the use of antiretroviral medications and increased length of survival, or the synergism of these factors. In this study we have calculated the 10-year CHD risk estimate and the prevalence of metabolic syndrome in a cohort of 118 HIV seropositive chronic drug users, including those who are on HAART with or without protease inhibitors (PI). The results showed that the 10-year coronary heart disease risk among the HIV seropositive drug users was 4.8 ± 5.7, which is within the range of results published for other HIV infected cohorts. The 10-year CHD risk was significantly higher in men (5.9±6.1, pmarijuana tended to be associated with increased central obesity (p=0.08). Heavy cigarette smoking was significantly associated with low HDL (OR=3.06, 95% CI:1.18; 7.95, p=0.02). The significant association of higher viral load with CHD risk indicates that controlling viral load may be important in reducing CHD risk in HIV infected drug users. PMID:18568100

    Full Text Available Data mining along with soft computing techniques helps to unravel hidden relationships and diagnose diseases efficiently even with uncertainties and inaccuracies. Coronary Heart Disease (CHD is akiller disease leading to heart attack and sudden deaths. Since the diagnosis involves vague symptoms and tedious procedures, diagnosis is usually time-consuming and false diagnosis may occur. A fuzzy system is one of the soft computing methodologies is proposed in this paper along with a data mining technique for efficient diagnosis of coronary heart disease. Though the database has 76 attributes, only 14 attributes are found to be efficient for CHD diagnosis as per all the published experiments and doctors’ opinion. So only the essential attributes are taken from the heart disease database. From these attributes crisp rules are obtained by employing CART decision tree algorithm, which are then applied to the fuzzy system. A Particle Swarm Optimization (PSO technique is applied for the optimization of the fuzzy membership functions where the parameters of the membership functions are altered to new positions. The result interpreted from the fuzzy system predicts the prevalence of coronary heart disease and also the system’s accuracy was found to be good.

    Editors' Summary Background. Coronary heart disease (CHD), the leading cause of death in most Western countries, is a “cardiovascular” disease—literally a disorder affecting the heart and/or blood vessels. In CHD, the blood vessels that supply the heart become increasingly narrow. Eventually, the flow of blood to the heart slows or stops, causing chest pains (angina), breathlessness, and heart attacks. Many factors increase the risk of developing CHD and other cardiovascular diseases, includi...

    Full Text Available Ravish Shah, Anil K AgarwalDivision of Nephrology, The Ohio State University, Columbus, Ohio, USAAbstract: Anemia is a frequent comorbidity of heart failure and is associated with poor outcomes. Anemia in heart failure is considered to develop due to a complex interaction of iron deficiency, kidney disease, and cytokine production, although micronutrient insufficiency and blood loss may contribute. Currently, treatment of anemia of heart failure lacks clear targets and specific therapy is not defined. Intravenous iron use has been shown to benefit anemic as well as nonanemic patients with heart failure. Treatment with erythropoietin-stimulating agents has been considered alone or in combination with iron, but robust evidence to dictate clear guidelines is not currently available. Available and emerging new agents in the treatment of anemia of heart failure will need to be tested in randomized, controlled studies.Keywords: anemia, heart failure, chronic kidney disease, elderly population

    Cardiac allograft vasculopathy remains one of the major causes of death post-heart transplantation. Its etiology is multifactorial and prevention is challenging. The aim of this study was to prospectively determine factors related to cardiac allograft vasculopathy after heart transplantation. This research was planned on 179 patients submitted to heart transplant. Performance of an early coronary angiography with endothelial function evaluation was scheduled at three-month post-transplant. Patients underwent a second coronary angiography after five-yr follow-up. At the 5- ± 2-yr follow-up, 43% of the patients had developed cardiac allograft vasculopathy (severe in 26% of them). Three independent predictors of cardiac allograft vasculopathy were identified: cardiogenic shock at the time of the transplant operation (OR: 6.49; 95% CI: 1.86-22.7, p = 0.003); early coronary endothelial dysfunction (OR: 3.9; 95% CI: 1.49-10.2, p = 0.006), and older donor age (OR: 1.05; 95% CI: 1.00-1.10, p = 0.044). Besides early endothelial coronary dysfunction and older donor age, a new predictor for development of cardiac allograft vasculopathy was identified: cardiogenic shock at the time of transplantation. In these high-risk patient subgroups, preventive measures (treatment of cardiovascular risk factors, use of novel immunosuppressive agents such as mTOR inhibitors) should be earlier and much more aggressive.

    2009-07-01

    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.

    2013-01-01

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

  11. Correlates of lung/heart ratio of thallium-201 in coronary artery disease

    International Nuclear Information System (INIS)

    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

    This study aims to find the relationship between quality of life and coping strategies in coronary heart disease patients. Two hundred coronary heart disease patients at Tehran Heart Center, who had been diagnosed with the disease 3 months before, were selected and filled out The Coping Inventory for Stressful Situations (CISS) and Quality of Life-SF36. Results showed a discrepancy between quality of life indices and coping strategies. Task-oriented strategy had a positive and significant relationship with total quality of life and PF indices while it had a negative and significant relationship with MH, RE and RP indices. Emotional-oriented strategy had a positive and significant relationship with RP and RE indices while it had a negative and significant relationship with PF, GH, PH, total psychological health and total quality of life indices. Avoidance-oriented strategy had a negative and significant relationship only with MH index. Furthermore, quality of life aspects (physical and psychological) had a positive and significant relationship with emotional-oriented strategy, but it did not have a significant relationship with task-oriented and avoidance-oriented strategies. Also, the social aspect of quality of life did not have a significant relationship with any of the strategies. Considering the effect of stress on decreasing the quality of life, we recommend a psychologist train coping strategies to coronary heart disease patients along with medical treatments in order to improve recovery, maintain health and reduce recurrence.

  13. Relationship of adiponectin level with lipid profile in type-2 diabetic men with coronary heart disease

    International Nuclear Information System (INIS)

    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)

    Various previous studies have reported the implication of CYP11B2 gene polymorphism in the pathophysiology of cardiovascular diseases. In particular, the -344T/C polymorphism, which is located at a putative binding site for the steroidogenic transcription factor (SF-1) has been associated with essential hypertension, left ventricular dilation and coronary heart disease. In the present study, we aim to determine the allele and genotype frequencies of the CYP11B2 gene in patients with clinical manifestation of coronary heart disease and confirmed by angiography and blood donors and to calculate the association of the gene polymorphism with CHD. A total of 79 DNA from patients with coronary heart disease admitted to the National Heart Institute and 84 healthy blood donors have been genotyped using polymerase chain reaction technique followed by restriction enzyme digestion (RFLP). Results of the study demonstrated that out of 79 for the patients, 40 were homozygous T, 10 were homozygous C and 29 were heterozygous TC. The frequencies of genotype TT, CC and TC for patients were 0.5, 0.13 and 0.36 respectively. The frequencies of allele T and C in patients were 0.68 and 0.31 respectively. While for the blood donors, 40 subjects were of homozygous T, 7 were homozygous C and 37 were heterozygous TC. The genotype frequencies for the TT, CC and TC were 0.47, 0.08 and 0.44 respectively. The frequency of the allele T was 0.69 and allele C was 0.3. Chi-Square analysis showed that there was no significant difference in the genotype and C allele frequencies between the CHD patients and the blood donors. Our study suggests that there is lack of association between -344T/C polymorphism of CYP11B2 gene and coronary heart disease.

  16. 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

    Full Text Available Background: Coronary heart disease is the leading cause of adult mortality and morbidity throughout the world. Well known risk factors independently or combined are involved in both atherosclerosis and myocardial infarction. Recent data have shown that viral and bacterial infections may also contribute to acute thromboembolic events; hence a case control study was carried out. Aims and Objective: To investigate the possible association between periodontal health and coronary artery disease, in patients with Acute Myocardial Infarction (AMI and Coronary Heart Disease (CHD. Material and Methods: 150 patients, 75 with AMI and 75 with CHD were included in the study. Data on hypertension, diabetes, smoking status and alcohol consumption were recorded. AMI patients were clinically examined 3-4 days after admission to the coronary care unit. Clinical examination of CHD patients was carried out during the hospital stay. All teeth excluding third molars were studied and clinical data were recorded regarding Plaque Index, Simplified Oral Hygiene Index, Gingival Index, Gingival Bleeding Index, Probing Depth and Clinical Attachment Loss. Results: Percentage of sites exhibiting bleeding on probing and the number of sites with more probing depth were significantly higher among AMI patients than those with CHD (P=0.05 and p=0.001 respectively.There was abundant plaque and debris around all tooth surfaces in AMI patients (p=0.001. Conclusion: Overall result of this case control study showed an association between periodontitis and acute myocardial infarction.

    To investigate the feasibility of MRI for non-invasive assessment of the coronary sinus (CS) and the number and course of its major tributaries in heart failure patients. Fourteen non-ischaemic heart failure patients scheduled for cardiac resynchronisation therapy (CRT) underwent additional whole-heart coronary venography. MRI was performed 1 day before device implantation. The visibility, location and dimensions of the CS and its major tributaries were assessed and the number of potential implantation sites identified. The MRI results were validated by X-ray venography conventionally acquired during the device implantation procedure. The right atrium (RA), CS and mid-cardiac vein (MCV) could be visualised in all patients. 36% of the identified candidate branches were located posterolaterally, 48% laterally and 16% anterolaterally. The average diameter of the CS was quantified as 9.8 mm, the posterior interventricular vein (PIV) 4.6 mm, posterolateral segments 3.3 mm, lateral 2.9 mm and anterolateral 2.9 mm. Concordance with X-ray in terms of number and location of candidate branches was given in most cases. Contrast-enhanced MRI venography appears feasible for non-invasive pre-interventional assessment of the course of the CS and its major tributaries. (orig.)

    Full Text Available Psoriasis vulgaris is a chronic inflammatory skin disease with an immune-genetic background. It has been reported as an independent risk factor for coronary heart disease (CHD in the United States and Europe. The purpose of this study was to investigate the association between psoriasis and CHD in a hospital-based population in Japan.For 113,065 in-hospital and clinic patients at our institution between January 1, 2011 and January 1, 2013, the diagnostic International Classification of Diseases (ICD-10 codes for CHD, hypertension, dyslipidemia, diabetes, and psoriasis vulgaris were extracted using the medical accounting system and electronic medical record, and were analyzed.The prevalence of CHD (n = 5,167, 4.5%, hypertension (n = 16,476, 14.5%, dyslipidemia (n = 9,236, 8.1%, diabetes mellitus (n = 11,555, 10.2%, and psoriasis vulgaris (n = 1,197, 1.1% were identified. The prevalence of CHD in patients with hypertension, dyslipidemia, diabetes, and psoriasis vulgaris were 21.3%, 22.2%, 21.1%, and 9.0%, respectively. In 1,197 psoriasis patients, those with CHD were older, more likely to be male, and had more number of the diseases surveyed by ICD-10 codes. Multivariate analysis showed that psoriasis vulgaris was an independent associated factor for CHD (adjusted odds ratio [OR]: 1.27; 95% confidence interval [CI]: 1.01-1.58; p = 0.0404 along with hypertension (adjusted OR: 7.78; 95% CI: 7.25-8.36; p < 0.0001, dyslipidemia (adjusted OR: 2.35; 95% CI: 2.19-2.52; p < 0.0001, and diabetes (adjusted OR: 2.86; 95% CI: 2.67-3.06; p < 0.0001.Psoriasis vulgaris was independently associated with CHD in a hospital-based population in Japan.

    Full Text Available Recent studies indicate a mutual epidemiological relationship between coronary heart disease (CHD and periodontitis. Both diseases are associated with similar risk factors and are characterized by a chronic inflammatory process. In a candidate-gene association study, we identify an association of a genetic susceptibility locus shared by both diseases. We confirm the known association of two neighboring linkage disequilibrium regions on human chromosome 9p21.3 with CHD and show the additional strong association of these loci with the risk of aggressive periodontitis. For the lead SNP of the main associated linkage disequilibrium region, rs1333048, the odds ratio of the autosomal-recessive mode of inheritance is 1.99 (95% confidence interval 1.33-2.94; P = 6.9 x 10(-4 for generalized aggressive periodontitis, and 1.72 (1.06-2.76; P = 2.6 x 10(-2 for localized aggressive periodontitis. The two associated linkage disequilibrium regions map to the sequence of the large antisense noncoding RNA ANRIL, which partly overlaps regulatory and coding sequences of CDKN2A/CDKN2B. A closely located diabetes-associated variant was independent of the CHD and periodontitis risk haplotypes. Our study demonstrates that CHD and periodontitis are genetically related by at least one susceptibility locus, which is possibly involved in ANRIL activity and independent of diabetes associated risk variants within this region. Elucidation of the interplay of ANRIL transcript variants and their involvement in increased susceptibility to the interactive diseases CHD and periodontitis promises new insight into the underlying shared pathogenic mechanisms of these complex common diseases.

    Full Text Available Abstract Background The protein of Niemann-pick type C1 gene (NPC1 is known to facilitate the egress of cholesterol and other lipids from late endosomes and lysosomes to other cellular compartments. This study aims to investigate whether the genetic variation in NPC1 is associated with risk of coronary heart disease (CHD and to detect whether NPC1 might interact with smoking on the risk of CHD. Methods We performed a case-control study, including 873 patients with coronary heart disease (CHD and 864 subjects without CHD as control. Polymorphisms of NPC1 gene were genotyped by polymerase chain reaction (PCR -restriction fragment length polymorphism (RFLP. Results A tag-SNP rs1805081 (+644A > G in NPC1 was identified. The G allele of the +644 locus showed reduced risk of CHD than wild-type genotype in Chinese population (recessive model GG vs. AG+AA: odds ratio [OR] 0.647, 95% CI 0.428 to 0.980, P = 0.039; additive model GG vs. AG vs. AA: OR 0.847, 95% CI 0.718 to 0.998, P = 0.0471. Moreover in smokers, the G-allele carriers had reduced risk of CHD compared with A-allele carries (OR 0.552, 95% CI 0.311 to 0.979, P = 0.0421. Conclusions The results of the present study suggest that NPC1 variants seem to be contributors to coronary heart disease occurrence in Chinese population. Moreover, in smokers, NPC1 variants seem to confer protection to coronary heart disease.

    The Visible Heart® Laboratory is an original experimental laboratory in which harvested animal hearts are resuscitated and connected to a support machine in order to beat outside the animal body. Resuscitated animal hearts may be exposed to various types of endovascular intervention under full, multimodality inspection. This unique experimental setting allows the performance of percutaneous coronary intervention (PCI) in a setting which resembles a standard catheterisation laboratory set-up, and contemporaneously allows unique multimodality imaging. For these reasons, the performance of PCI on bifurcations in the Visible Heart® Laboratory may improve the knowledge of the dynamic stent deformations and stent-vessel wall interactions associated with the different steps of the various techniques for bifurcation stenting. Furthermore, the collected images may also serve as a novel educative resource for physicians. The performance of bifurcation stenting in the Visible Heart® Laboratory is a promising experimental setting to gain novel information regarding any existing or future PCI technique to treat coronary bifurcations.

Results: After being treated with SMI for 3 weeks, in the treated group, blood level of NO was raised significantly from 69.8 ± 33.1 μ mol/L to 120.1 ± 50.8 μ mol/L, and ET-1 was lowered from 70.1 ± 32.1 ng/L to 46.2±21.3 ng/L, respectively (P<0.01); that of Ang Ⅱ was lowered from 81.3 ± 24.3 ng/L to 50.2 ± 27.3 ng/L (P<0.01); brachial arterial post-congestion blood flow increasing rate was raised from 389.4 ± 26.3% to 459.3 ± 27.8% (P<0.01); and the improvement in heart function as seen through the ejection fraction (EF) was increased from 44 ± 5% to 68 ± 6% (P<0.01), all the changes being more significant than those in the control group (all P<0.01). Conclusion: SMI can improve not only the endothelial function in CHD-DM patients, but also heart contraction significantly.

    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.

    The preliminary effects of a transtheoretical model-based exercise stage-matched intervention on exercise behavior in sedentary patients with coronary heart disease were examined in this study. This was a pilot randomized, controlled trial. A total of 18 eligible patients with coronary heart disease were recruited and randomized to either a conventional group, a patient-education group, or an exercise stage-matched intervention group. Exercise behavior was measured by exercise stages of change, exercise self-efficacy, exercise decisional balance, and moderate-intensity exercise duration (min/week) at baseline and immediately after the eight week intervention. When compared to baseline, only patients in the exercise stage-matched intervention group demonstrated significant progress in the exercise stages of change, higher exercise self-efficacy, fewer exercise barriers, and longer duration of moderate-intensity exercise after the eight week intervention. A significant difference in the progress in the exercise stages of change was found among the three groups after the eight week intervention. The findings suggest that the transtheoretical model-based exercise stage-matched intervention has potentially-positive effects on motivating sedentary patients with coronary heart disease to engage in exercise.

    In patients with coronary heart disease the further course of the disease can be substantially influenced by means of a targeted treatment of risk factors. A reduction of hospital referrals, an improvement in quality of life and an extension in life expectation by secondary prophylactic measures have been well documented. In addition to an optimized medicinal therapy, an often drastic change in lifestyle with a focus on a consistent abstinence from nicotine, a healthy diet and regular physical exercise is necessary. Data from healthcare research show that these targets are only insufficiently achieved. The implementation of current guidelines should therefore be rigorously applied. There is a need for research particularly with respect to the prognostic significance of beta blocker therapy for patients with stable coronary heart disease and preserved left ventricular function, the prognostic significance of targeted weight loss for overweight or obese coronary heart disease patients, the effectiveness of psychosocial interventions in the various patient groups and their implementation into routine care. Research is also necessary with respect to optimization of structured rehabilitation programs and improvement in patient compliance.

  15. Quantitative Determination of Fibrinogen of Patients with Coronary Heart Diseases through Piezoelectric Agglutination Sensor

    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.

    2014-11-01

    Full Text Available Chronic Kidney disease (CKD is a pressing public health burden occurring in about 10% of the population. The majority of them die before reaching End Stage Renal Disease (ESRD due to cardiovascular disease (CVD. Hypertension (HTN and anaemia are two reversible factors for progression of CKD. Besides asymptomatic coronary artery disease, the electrolyte abnormalities such as hyperkalaemia and hypocalcaemia also subject these patients to sudden cardiac death. This study is aimed at to see the changes in electrocardiogram (ECG in hospitalized predialytic CKD patients due to these abnormalities. Methods: This is a 6 months cross-sectional study carried out at Chittagong Medical College Hospital in Chittagong, Bangladesh. 50 patients with stages 3, 4 and 5 CKD were recruited from the Nephrology and Medicine wards. Patients with prior history of coronary artery disease, cardiomyopathy, valvular heart disease and dialysis were excluded. All had their standard 12–lead electrocardiogram (ECG recorded and various findings were critically studied and interpreted independently by two consultant physicians including a cardiologist. Data analysis was done using SPSS version 19. Results: LVH (left ventricular hypertrophy (66%, LAE (left atrial enlargement (30% and unrecognized myocardial infarction (28% were very common ECG abnormalities in our predialytic CKD patients. HTN, anaemia, late presentation, and male gender appear to be associated with ECG abnormalities. Though 28 patients (56% were hyperkalaemic only 9 patients (38% of them had tall tented T wave in ECG. Conclusion: Detection of HTN and anaemia in male predialytic CKD patients will arouse suspicion which will help in early detection of cardiac outcome by ECG abnormality which will help in taking treatment strategy in resource limited country.

    International Nuclear Information System (INIS)

    The goal of this study was to investigate imaging results from a coronary CT angiography (CCTA) in chronic coronary total occlusion (CTO) before percutaneous coronary intervention (PCI). In 74 patients with CTO, 34 patients was evaluated by using a 64-row multidetector CT scanner prior to the PCI and 40 control subjects with CTO, who only took PCI, were included. The multiplanar reformation of the heart chambers and three-dimensional CT images were used for determining an optimal view. We analyzed and evaluated the success rates of PCI, length of occluded vessel, calcified plaques, occluded side-branches, tapered occlusion, > 45 degrees angulation of occluded artery, and myocardial density < 50 Hounsfield unit (HU). Success rates of PCI in the two groups, the control group and the experimental group, were not statistically different (p > 0.05). The mean length of occluded arteries was measured as 25 +/- 11 mm and 26 cases (74%) had an occlusion length > 2 cm. Calcified plaques proximal to occlusion were detected in 19 cases (54%). Occluded side branches, tapered occlusion, > 45 degrees angulation of occluded artery, and myocardial density < 50 HU were in 11 cases (32%), 9 cases (27%), 6 cases (18%), and 5 cases (15%), respectively. Although there was no correlation between the CCTA findings before PCI and the success rate of PCI, common findings of CCTA in CTO included an occlusion length > 2 cm and calcified plaques proximal to occluded arteries.

    2014-10-01

    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.

    Heart failure (HF) poses a significant economic burden on our health-care resources with very high readmission rates. Remote monitoring has a substantial potential to improve the management and outcome of patients with HF. Readmission for decompensated HF is often preceded by a stage of subclinical hemodynamic decompensation, where therapeutic interventions would prevent subsequent clinical decompensation and hospitalization. Various methods of remote patient monitoring include structured telephone support, advanced telemonitoring technologies, remote monitoring of patients with implanted cardiac devices such as pacemakers and defibrillators, and implantable hemodynamic monitors. Current data examining the efficacy of remote monitoring technologies in improving outcomes have shown inconsistent results. Various medicolegal and financial issues need to be addressed before widespread implementation of this exciting technology can take place. PMID:23018667

    With high mortality and readmission rates among patients with heart failure (HF), multiple disease management models have been and continue to be tested, with mixed results. Early postdischarge care improves outcomes for patients. Telemonitoring also can assist in reducing mortality and HF-related hospitalizations. Office-based team care improves patient outcomes, with important components including rapid access to physicians, partnerships with clinical pharmacists, education, monitoring, and support. Pay-for-performance measures developed for HF, primarily use of angiotensin-converting enzyme inhibitors and beta blockers, also improve patient outcomes, but the influence of adherence to other measures has been minimal. Evaluating comorbid conditions, including diabetes and hypertension, and making drug adjustments for patients with HF to include blood pressure control and use of metformin, when possible, can reduce mortality and morbidity.

    The objective of this study was to assess factors affecting image quality of 320-row computed tomography angiography (CTA) of coronary arteries in children with congenital heart disease (CHD). We retrospectively reviewed 28 children up to 3 years of age with CHD who underwent prospective electrocardiography (ECG)-gated 320-row CTA with iterative reconstruction. We assessed image quality of proximal coronary artery segments using a five-point scale. Age, body weight, average heart rate, and heart rate variability were recorded and compared between two groups: patients with good diagnostic image quality in all four coronary artery segments and patients with at least one coronary artery segment with nondiagnostic image quality. Altogether, 96 of 112 segments (85.7 %) had diagnostic-quality images. Patients with nondiagnostic segments were significantly younger (10.0 ± 11.6 months) and had lower body weight (5.9 ± 2.9 kg) (each p heart rate and heart rate variability between the two imaging groups were not significant. Receiver operating characteristic analyses for predicting patients with nondiagnostic image quality revealed an optimal body weight cutoff of ≤5.6 kg and an optimal age cutoff of ≤12.5 months. Prospective ECG-gated 320-row CTA with iterative reconstruction provided feasible image quality of coronary arteries in children with CHD. Younger age and lower body weight were factors that led to poorer image quality of coronary arteries.

    Renal digoxin clearance was compared in patients suffering from atrial fibrillation with well preserved cardiac function (n = 9; salt intake +/- 170 mmol daily) and patients with chronic congestive heart failure (n = 10; salt intake 50 mmol daily and maintenance treatment with diuretics). There was no difference between the groups concerning digoxin dosage, creatinine clearance, diuresis or sodium excretion in the urine. Digoxin clearance in chronic heart failure proved to be significantly lower than in atrial fibrillation (48 +/- 21 vs 71 +/- 36 ml X min-1, p less than 0.05), and Cdig/Ccreat was similarly reduced at 0.73 +/- 0.15 compared to 1.09 +/- 0.27 (p less than 0.005). Steady state serum digoxin concentration was significantly higher in patients with congestive heart failure (1.44 +/- 0.47 vs 0.87 +/- 0.33 micrograms X 1(-1), p less than 0.01). Chronic congestive heart failure is a state with reduced digoxin clearance by the kidney, which could lead to digoxin intoxication not explicable by overdose, reduced renal function or the effect of interacting drugs.

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.

    To explore the relation of angiotensin-converting enzyme (ACE) and angiotensin Ⅱ type 1 receptor (AT1R) gene polymorphism with coronary heart disease (CHD) and the severity of coronary artery stenosis, 130 CHD patients who underwent coronary angiography were examined for the number of affected coronary vessels (≥75% stenosis) and coronary Jeopardy score. The inser- tion/deletion of ACE gone polymorphism and ATIR gene polymorphism (an A→C transversion at nucleotide position 1166) were detected by using polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) in CHD patients and 90 healthy serving as controls. The re- sults showed that DD genotype and of ACE were more frequent in CHD patients than that in control group (38.5% vs 14.4%, P<0.001). The frequency of the AT1R A/C genotypes did not differ between the patients and the controls (10% vs 13.1%, P0.05). The relative risk associated with the ACE-DD was increased by ATIR-AC genotype. Neither the number of affected coronary vessels nor the coro-nary score differed among the ACE I/D genotypes (P0.05). But the number of affected coronary vessels and the coronary score were significantly greater in the patients with the AT1R-AC genotype than in those with the AA genotype (P<0.05). In conclusion, DD genotype may he risk factor for CHD and MI in Chinese people, and is not responsible for the development of the coronary artery stenosis. The AT1R-C allele may increase the relative risk associated with the ACE-DD genotype, and may be involved in the development of the stenosis of coronary artery.

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

    Full Text Available Background: Percutaneous coronary intervention (PCI of chronic total occlusion (CTO is one of the most challenging procedures in interventional cardiology. New techniques and devices have made possible to face these complex procedures. Intravascular ultrasound (IVUS reveals special features and contributes greatly to procedural success.Method: We analysed retrospectively IVUS contribution and findings in 23 cases of a total 46 CTOs PCI from February 2009 to August 2010 in our cath lab. Both true and functional CTO were included in this study. The procedure was considered successful when a TIMI III flow was reached in the occluded vessel after stent implantation with a residual stenosis less than 30%. IVUS features and contribution in CTO-PCI were analysed. All data were introduced in SPSS version 15 (SPSS Inc. Chicago, Illinois, USA. Continuous variables were described by mean ± SD and categorical variables were expressed as percentage. A P<0.05 was considered statistically significant.Results: 46 PCIs in 34 patients were performed during 19 months in our centre. The procedure was successful in 28 cases (60.9%.. IVUS was performed in 23 (82.1% of successful procedures. IVUS revealed calcium somewhere in 17 (73.9%. Despite wire angiographic verification in true lumen distally IVUS showed subintimal wire position in part of CTO segment in 6(26.1%. In 22(95.7% of cases IVUS allowed both the wire position verification in true lumen and the vessel measurement before stent implantation. In 1(4.3% case a second wire was introduced into true lumen guided by IVUS after realising that the first wire was in false lumen. We could not find significant relation between calcium presence and subintimal wire penetration in CTO segment (p: 0.14 Conclusions: IVUS showed calcium in CTO segment in a high percentage of cases. It is not unusual to find wire penetration in subintimal space in part of CTO segment. IVUS has a key contribution in the step by step

  16. Polymorphism in Apoprotein-C III gene and coronary heart disease

    International Nuclear Information System (INIS)

    The aim of this study was to look into the association, if any, apoprotein-CIII variant allele with hypertriglyceridemia, hypercholesterolemia and coronary heart disease (CHD). The prevalence of a C to G substitution in the 3 untranslated regions of apoprotein-CIII was studied in a sample of 92 angiographed Saudi subjects, consisting of 65 males and 27 females. The subjects were genotyped by amplification followed by digestion of the gene fragment containing the polymorphic site with Sac I restriction enzyme. The variant allele of apoprotein-CIII was found to be associated neither with hypertriglyceridemia nor with hypercholesterolemia. However, a significant association of this allele (P<0.01) was found with coronary heart disease, independent of other risk factors such as smoking, diabetes and hypertension. An estimation of odds ratio using logistic regression with various risk factors in the model showed that the individuals with this rare allele were 3.4 times more at risk of developing coronary disease. This estimation of risk held even after analyzing a subset of individuals above 45 years of age. While the association between apoprotein-CIII variant allele and dyslipidemia could not be established in this study, the relationship between this marker and CHD was highlighted in the studied subjects.

    Full Text Available Background: Angiogenesis gene therapy has long been sought as a novel alternative treatment for restoring the blood flow and improving the contractile function of the ischemic heart in selected clinical settings. Angiogenic fibroblast growth factor-1 (FGF-1 is a promising candidate for developing a promising gene therapy protocol due to its multipotent ability to stimulate endothelial cell (EC growth, migration, and tube formation. Despite these advantages, however, FGF gene therapy has suffered setbacks mainly due to the inefficient delivery rate of the growth factor in vivo. Given the potent angiogenic effect of FGF-1, we reasoned that constitutively synthesized minute quantities of this polypeptide hormone, when empowered with the ability to escape the cellular constraint, could freely act in a paracrine/autocrine fashion on nearby existing capillary plexuses and lead to neovascularization and restoration of the blood flow to ischemic tissues for reparative purpose. Methods: We report the direct gene transfer of a retroviral-based mammalian expression vector encoding a secreted form of FGF-1 (sp-FGF-1 for the purpose of therapeutic angiogenesis into the porcine myocardium subjected to the surgical placement of an ameroid occluder to induce the chronic coronary occlusion of the left circumflex coronary artery (LCx and regional myocardial ischemia. Coronary angiography, performed 3 weeks after surgery, confirmed the interruption of the blood flow in the LCx distal to the site of ameroid placement. Results: Immunohistochemical analysis using antibody specific to von Willebrand factor (vWF, an endothelial marker, showed a significant increase (p<0.05 in myocardial vascularity in the sp-FGF-1 hearts compared to the control (vector alone. Importantly, an assessment of the cardiac function by echocardiography, performed 3 weeks after surgery, demonstrated improved cardiac contractility due to increased left ventricular free wall contraction in the

    Strong socioeconomic inequalities exist in cardiovascular mortality and morbidity. The current review aims to synthesize the current evidence on the association between socioeconomic status (SES) and access to treatment of coronary heart disease (CHD). We examined quantitative studies analyzing the relationship between SES and access to CHD treatment that were published between 1996 and 2015. Our data sources included Medline and Web of Science. Our search yielded a total of 2066 records, 57 of which met our inclusion criteria. Low SES was found to be associated with low access to coronary procedures and secondary prevention. Access to coronary procedures, especially coronary angiography, was mainly related to SES to the disadvantage of patients with low SES. However, access to drug treatment and cardiac rehabilitation was only associated with SES in about half of the studies. The association between SES and access to treatment for CHD was stronger when SES was measured based on individual-level compared to area level, and stronger for individuals living in countries without universal health coverage. Socioeconomic inequalities exist in access to CHD treatment, and universal health coverage shows only a minor effect on this relationship. Inequalities diminish along the treatment pathway for CHD from diagnostic procedures to secondary prevention. We therefore conclude that CHD might be underdiagnosed in patients with low SES. Our results indicate that there is an urgent need to improve access to CHD treatment, especially by increasing the supply of diagnostic angiographies, to reduce inequalities across different healthcare systems.

    Background Variability of blood pressure (BP) across outpatient visits is frequently dismissed as random fluctuation around a patient’s underlying BP. Objective: Examine the association between visit-to-visit variability (VVV) of systolic and diastolic BP (SBP and DBP) on cardiovascular disease and mortality outcomes. Design Prospective cohort study Setting Post-hoc analysis of the Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT). Participants 25,814 ALLHAT participants. Measurements VVV of SBP was defined as the standard deviation (SD) across BP measurements obtained at 7 visits conducted from 6 to 28 months following ALLHAT enrollment. Participants free of cardiovascular disease events during the first 28 months of follow-up were followed from the month 28 study visit through the end of active ALLHAT follow-up. Outcomes included fatal coronary heart disease or non-fatal myocardial infarction, all-cause mortality, stroke and heart failure. Results There were 1194 cases of fatal CHD or non-fatal MI, 1948 deaths, 606 cases of stroke and 921 cases of heart failure during follow-up. After multivariable adjustment including mean SBP, the hazard ratio comparing participants in the highest versus lowest quintile of SD of SBP (≥14.4 mmHg versus <6.5 mmHg) was 1.30 (1.06–1.59) for fatal coronary heart disease or non-fatal myocardial infarction, 1.58 (1.32–1.90) for all-cause mortality, 1.46 (1.06–2.01) for stroke, and 1.25 (0.97–1.61) for heart failure. Higher VVV of DBP was also associated with cardiovascular disease events and mortality. Limitations Long-term outcomes were not available. Conclusions Higher VVV of SBP is associated with increased cardiovascular disease and mortality risk. Future studies should examine whether reducing VVV of BP lowers this risk.

    The aim of this study was to determine the impact of multi-slice computed tomography (MSCT) evaluation of coronary artery stenosis on left heart structure and systolic function. Coronary artery CT angiography was performed in 200 patients diagnosed with coronary heart disease, and then according to the AHA coronary artery 17-segment fractionation method, the Gensini score (GS) was determined for every narrow segment, and one-stop assessment of the correlation between left heart structure and function was performed. After the grouping of GS quartiles from low to high, there were differences between different patients with regard to LVDD, LADD, LVEDV, LVESV, MM, LVEF, and FS, while no difference in SV and CO. GS showed linear negative correlation with LVEF and FS, and linear positive correlation with LVDD, LADD, LVEDV, LVESV, and MM, while no correlation with SV and CO. That is, GS of coronary artery stenosis was negatively correlated with left ventricular systolic function and positively correlated with myocardial mass. The narrower the coronary artery, the worse the cardiac function and the higher the myocardial hypertrophy. Coronary artery stenosis was one of the important causes of the decrease in left ventricular systolic function and cardiac remodeling.

    Full Text Available After severe myocardial infarction (MI, heart failure results from ischemia, fibrosis, and remodeling. A promising therapy to enhance cardiac function and induce therapeutic angiogenesis via a paracrine mechanism in MI is myoblast sheet transplantation. We hypothesized that in a rat model of MI-induced chronic heart failure, this therapy could be further improved by overexpression of the antiapoptotic, antifibrotic, and proangiogenic hepatocyte growth factor (HGF in the myoblast sheets. We studied the ability of wild type (L6-WT and human HGF-expressing (L6-HGF L6 myoblast sheet-derived paracrine factors to stimulate cardiomyocyte, endothelial cell, or smooth muscle cell migration in culture. Further, we studied the autocrine effect of hHGF-expression on myoblast gene expression profiles by use of microarray analysis. We induced MI in Wistar rats by left anterior descending coronary artery (LAD ligation and allowed heart failure to develop for 4 weeks. Thereafter, we administered L6-WT (n = 15 or L6-HGF (n = 16 myoblast sheet therapy. Control rats (n = 13 underwent LAD ligation and rethoracotomy without therapy, and five rats underwent a sham operation in both surgeries. We evaluated cardiac function with echocardiography at 2 and 4 weeks after therapy, and analyzed cardiac angiogenesis and left ventricular architecture from histological sections at 4 weeks. Paracrine mediators from L6-HGF myoblast sheets effectively induced migration of cardiac endothelial and smooth muscle cells but not cardiomyocytes. Microarray data revealed that hHGF-expression modulated myoblast gene expression. In vivo, L6-HGF sheet therapy effectively stimulated angiogenesis in the infarcted and non-infarcted areas. Both L6-WT and L6-HGF therapies enhanced cardiac function and inhibited remodeling in a similar fashion. In conclusion, L6-HGF therapy effectively induced angiogenesis in the chronically failing heart. Cardiac function, however, was not further

    Biomarkers of cardiovascular diseases are indispensable tools for diagnosis and prognosis, and the use of several biomarkers is now considered the standard of care. New markers continue to be developed, but few prove to be substantially better than established markers. Suppression of tumorigenicity 2 (ST2) is a marker of cardiomyocyte stress and fibrosis that provides incremental value to natriuretic peptides for risk stratification of patients with a wide spectrum of cardiovascular diseases. On the basis of all available data, the 2013 American College of Cardiology and American Heart Association guidelines now recommend measurement of ST2 for additive risk stratification in patients with acute or chronic ambulatory heart failure (HF). This report provides an up-to-date overview of the clinical studies that led to the endorsement of ST2 as a cardiovascular prognostic marker in chronic HF. The presented data suggest that the addition of ST2 to a model that includes established mortality risk factors, including natriuretic peptides, substantially improves the risk stratification for death and HF hospitalization in patients with HF. ST2's prognostic value remains strong even in the subset of patients with renal insufficiency and is superior to other remodeling-fibrosis biomarkers currently being evaluated. In conclusion, these results have been repeatedly validated; thus, ST2 could be rapidly incorporated into clinical practice for risk prediction. Indeed, the body of evidence supporting the use of ST2 in chronic HF stratification continues to grow, with consistent data from cohorts around the world in single-center (Barcelona, Brussels, and San Diego cohorts) and multicenter (Penn Heart Failure Study [PHFS] and Muerte Subita en Insuficiencia Cardiac [MUSIC]) studies and in post hoc studies from clinical trials (Prospective Randomized Amlodipine Survival Evaluation 2 [PRAISE-2], Heart Failure: A Controlled Trial Investigating Outcomes of Exercise Training [HF

    Lindsay M K Wallace

    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.

    Full Text Available SUMMARY Introduction: chronic Chagas heart disease (CCHD is the most common manifestation of American Trypanosomiasis, causing about 50,000 deaths annually. Several factors bear correlation with the severity of CCHD. However, to our knowledge, the assessment on the contribution of major cardiovascular risk factors (CRF, such as hypertension and atherogenic dyslipidemia (AD to CCHD severity is scarce, despite their well-established role in coronary artery disease, heart failure and stroke. Objective: to explore the potential relationship of blood pressure and AD with the clinical profile of patients with CCHD. Methods: we performed a cross-sectional study in T. cruziseropositive patients categorized according to a standard CCHD classification. All individuals were subjected to complete clinical examination. Autoantibodies induced by T. cruzi were assessed by ELISA. Results: we observed that Atherogenic index (AI levels rose significantly in relation to the severity of the CCHD stage, with CCHD III cases showing the highest values of AI. Furthermore, those patients with globally dilated cardiomyopathy with reduced ejection fraction showed higher levels of AI. In regard to autoantibodies, anti-B13 also showed relation with the severity of the disease. Conclusion: we observed that AI correlated with CCHD stages and contributed, in association with anti-B13 antibodies and age, to the prediction of systolic heart failure.

    Introduction: We evaluated the association between two single nucleotide polymorphisms of the vascular endothelial growth factor gene and one of the hypoxia-inducible factor-1α gene and the degree of coronary collateral formation in patients with a coronary chronic total occlusion. Methods: Totally, 98 patients with symptomatic coronary artery disease and a chronic total occlusion observed during coronary angiography were recruited. Genotyping of two vascular endothelial growth factor promoter single nucleotide polymorphisms (−152G>A and −165C>T) and the C1772T single nucleotide polymorphism of hypoxia-inducible factor-1α were performed using polymerase chain reaction and restriction fragment length polymorphism analysis. The presence and extent of collateral vessel filling was scored by blinded observers using the Rentrop grade. Results: We found no association between the vascular endothelial growth factor −152G>A, −165C>T and hypoxia-inducible factor-1α −1772C>T with the presence and filling of coronary collateral vessels. A history of percutaneous coronary intervention and transient ischaemic attack/cerebrovascular accident were associated with the presence of enhanced collateral vessel formation following binary logistic regression analysis. Conclusion: The study findings suggest that coronary collateral formation is not associated with the tested polymorphic variants of vascular endothelial growth factor and hypoxia-inducible factor-1α in patients with symptomatic coronary artery disease and the presence of a chronic total occlusion.

  10. Optimal medical therapy in chronic heart failure-an audit

    International Nuclear Information System (INIS)

    Objective: Systolic heart failure is a chronic condition with significant morbidity and mortality. Evidence based optimal medical therapy (OMT) has been shown to reduce mortality. Underuse of OMT due to multiple reasons has been a consistent problem. The study objective was to audit the use of OMT in patients with heart Failure. Study Design: Descriptive study. Place and Duration of study: This audit was carried out in AFIC-NIHD from April 2011- February 2012. Material and Methods: Seventy consecutive stage D heart failure patients were included in the study. The patients were assessed clinically by a cardiologist and all previous documentations, referral letters, prescriptions, and purchase receipts were reviewed. To identify any other medication patients might have been taking (which did not appear on the prescriptions) patients were asked to identify common medicine packs. The patients underwent a detailed clinical evaluation including history, physical examination. Relevant investigations were done. ACCF/AHA (American College of Cardiology Foundation / American Heart Association) and ESC (European Society of Cardiology) guidelines for the diagnosis and treatment of acute and chronic heart failure were taken as standard of care. Results: In our audit we found that a large proportion of patients who were at high risk as per the Seattle Heart Failure Model (SHFM) were not on OMT, only 4.3% of the patients were on beta blockers that have been shown to improve mortality in the large randomized clinical trials, 64.3% were not taking any beta blockers where as 55.7% were not on ACE inhibitors and adding the OMT greatly reduced their mortality risk. Conclusions: We concluded that a large proportion of patients were not on OMT despite not having any contraindication to such therapy. This deprives them of significant survival benefit. (author)

    To investigate the feasibility of introcoronary cell infusion into nonischemic heart failure (HF) heart and whether different types of stem cell transplantation would affect heart function to a similar degree. Japanese white ears rabbits were used as HF models by intravenous injection adriamycin. Autologous bone marrow mononuclear cells(BMCs), bone marrow stromal cells (MSCs), skeletal myoblasts (SMs) or culture medium were infused into coronary arteries respectively by occluding the root of ascending aorta. The mortality during and 4 weeks after the procedure the mortality was 7.1% and 16.7% respectively. After 4 weeks, the ejection fraction (EF) in BMCs group had significant improvement (P 0.05). In sham group,the left ventricular endostolic diameter (LVED) had significant enlargement (P 0.05). Immunofluorescence revealed de novo expression of cardiac troponin I in BMCs and MSCs groups, cardiac troponin I was not detected in SMs group. In conclusions, intracoronary cell transplantation could provide effective cell delivery into dilated cardiomyopathy hearts and could be a useful strategy for treating CHF, BMCs cell transplantation may be the first choice in all the above cell types.

    Chronic sleep deprivation is associated with cardiovascular events. In addition, autonomic activity determined from the levels of the heart rate variability (HRV), plasma catecholamine, and intracellular magnesium (Mg) are important in the pathophysiology of cardiovascular events. This study therefore aimed to determine the effects of chronic sleep deprivation on autonomic activity by examining the HRV, plasma catecholamine, and intracellular magnesium levels. Thirty (30) healthy male college students ranging in age from 20 to 24 years of age (average 22 +/- 1 years; mean +/- SD) with no coronary risk factors such as hypertension, diabetes mellitus, hyperlipidemia or a family history of premature coronary artery disease (CAD) were included in the study. Over a 4-week period, the volunteers' plasma levels of epinephrine, norepinephrine, and erythrocyte-Mg were measured. The study was made during the 4 weeks before and immediately after college finals exams. HRV, obtained from 24-hour ambulatory ECG monitoring, included time and frequency domain indices. The HRV indices and erythrocyte-Mg decreased while norepinephrine increased during chronic sleep deprivation. It is concluded that chronic sleep deprivation causes an autonomic imbalance and decreases intracellular Mg, which could be associated with chronic sleep deprivation-induced cardiovascular events.

  14. Systolic reconstruction in patients with low heart rate using coronary dual-source CT angiography

    International Nuclear Information System (INIS)

    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.

    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 To detection of chlamydia pneumoniae (Cpn) DNA in the circulating mononuclear cell fractions of coronary heart disease and to investigate the association between infection with chlamydia pneumoniae and coronary heart disease (CHD) and prospectively whether blood -based nested polymerase chain reaction ( nPCR ) is useful in identifying Cpn infection. Methods The peripheral blood mononuclear cell (PBMC) Cpn DNA was examined using nPCR technique and confirmed by electrophoresis in 150 patients with CHD. Select 55 patients with clinical suspected CHD but angiography result are normal as control group (CG). Then we conducted a prospective , randomized, double - blind, placebo -controlled study of 6 months of azithromycin and placebo treatment in CHD group. Patients with Cpn DNA positive were then randomized to receive azithromycin or placebo. After treatment blood sample were collected for repeated measurement . Results Chlamydia pneumoniae DNA was detected in 49(32.7% ) of 150persons with CHD and in 1 ( 1.8% ) of 55 persons with control group,odds ratio 26.2, 95% confidence interva13.52 - 194.98. The positivity rates of nPCR in CHD groups were higher than those in control group. 16 cases (29. 1% ) in latent coronary heart diseases(LCHD) group , 19 cases (39.6%) in unstable angina(UAP) group ,and 14 cases (29.9%) in acute myocardial infarction (AMI)group were Cpn positive by nPCR. There were no significant difference among in AMIUAP and LCHD group. There were significiant difference in Cpn DNA negative rates after the azithromycin and the placebo treatment. Conclusions Chlamydia pneumoniae is present in PBMC of a significant proportion of persons with CHD. The potential role of chlamydia pneumoniae in coronary atherosclerosis may therefore be more related to acceleration of disease or systemic effects by persistent infection than to sudden initiation of progressive coronary artery disease by acute infection. The detection of Cpn DNA in PBMC with nPCR may be

    The anomalous aortic origin of a coronary artery from the wrong sinus of Valsalva with interarterial, intramural, and/or intraconal course is a rare congenital anomaly that is associated with a high risk of sudden death in children. The Congenital Heart Surgeons' Society established the Registry of Anomalous Aortic Origin of the Coronary Artery to help determine the outcome of children and young adults managed with surgical intervention versus observation and to test the hypothesis that subsets of patients with anomalous aortic origin of a coronary artery can be identified in whom the risk of intervention is less than the risk of observation. All institutional members of the Congenital Heart Surgeons' Society were recruited for participation. The registry consists of a retrospective cohort of patients diagnosed between 1 January, 1998 and 20 January, 2009 and a prospective, population-based cohort of patients newly diagnosed from 21 January, 2009 onwards. Baseline demographics, diagnoses, and results of tests will be obtained through a review of the medical records. Annual follow-up data will be collected. Data will be analysed for different factors of risk at diagnosis, different strategies of treatment, and the impact of both on the outcomes of the patients. As of June 2010, 28 institutions had applied for approval from their institutional review board and 16 institutions had received approval from their institutional review board. Seventy-four patients have enrolled to date. We hope to use the established Pediatric Cardiomyopathy Registry as a guide to successful implementation, with a cooperative effort between institutions. The overall purpose of the Registry of Anomalous Aortic Origin of the Coronary Artery is to determine the outcome of surgical intervention versus observation in children and young adults with anomalous aortic origin of a coronary artery, and to describe the natural and "unnatural" history of these patients over the course of their lifetime

    Objectives Coronary heart disease is the leading cause of death worldwide, and it is important to diagnose the level of the disease. Intelligence systems for diagnosis proved can be used to support diagnosis of the disease. Unfortunately, most of the data available between the level/type of coronary heart disease is unbalanced. As a result system performance is low. Methods This paper proposes an intelligence systems for the diagnosis of the level of coronary heart disease taking into account the problem of data imbalance. The first stage of this research was preprocessing, which included resampled non-stratified random sampling (R), the synthetic minority over-sampling technique (SMOTE), clean data out of range attribute (COR), and remove duplicate (RD). The second step was the sharing of data for training and testing using a k-fold cross-validation model and training multiclass classification by the K-star algorithm. The third step was performance evaluation. The proposed system was evaluated using the performance parameters of sensitivity, specificity, positive prediction value (PPV), negative prediction value (NPV), area under the curve (AUC) and F-measure. Results The results showed that the proposed system provides an average performance with sensitivity of 80.1%, specificity of 95%, PPV of 80.1%, NPV of 95%, AUC of 87.5%, and F-measure of 80.1%. Performance of the system without consideration of data imbalance provide showed sensitivity of 53.1%, specificity of 88,3%, PPV of 53.1%, NPV of 88.3%, AUC of 70.7%, and F-measure of 53.1%. Conclusions Based on these results it can be concluded that the proposed system is able to deliver good performance in the category of classification. PMID:26893948

    Full Text Available Abstract Background Coronary heart disease (CHD is a common medical problem in general practice. Due to its chronic character, shared care of the patient between general practitioner (GP and cardiologist (C is required. In order to improve the cooperation between both medical specialists for patients with CHD, a local treatment pathway was developed. The objective of this study was first to evaluate GPs’ opinions regarding the pathway and its practical implications, and secondly to suggest a theoretical framework of the findings by feeding the identified key factors influencing the pathway implementation into a multi-dimensional model. Methods The evaluation of the pathway was conducted in a qualitative design on a sample of 12 pathway developers (8 GPs and 4 cardiologists and 4 pathway users (GPs. Face-to face interviews, which were aligned with previously conducted studies of the department and assumptions of the theory of planned behaviour (TPB, were performed following a semi-structured interview guideline. These were audio-taped, transcribed verbatim, coded, and analyzed according to the standards of qualitative content analysis. Results We identified 10 frequently mentioned key factors having an impact on the implementation success of the CHD treatment pathway. We thereby differentiated between pathway related (pathway content, effort, individual flexibility, ownership, behaviour related (previous behaviour, support, interaction related (patient, shared care/colleagues, and system related factors (context, health care system. The overall evaluation of the CHD pathway was positive, but did not automatically lead to a change of clinical behaviour as some GPs felt to have already acted as the pathway recommends. Conclusions By providing an account of our experience creating and implementing an intersectoral care pathway for CHD, this study contributes to our knowledge of factors that may influence physicians’ decisions regarding the use

    Full Text Available The possibility to stabilize and reverse the atherosclerotic plaques in coronary arteries due to therapy with atorvastatin and rosuvastatin was demonstrated in recent studies. The advantage of aggressive lipid-lowering therapy compared with standard therapy is proven in patients with both stable and acute forms of ischemic heart disease (IHD. Pleiotropic effects, in particular, effect on endothelial function, ability to reduce the blood level of C-reactive protein are important in the statins mode of action. Risk reduction of cardiovascular complications and slow down of atherosclerosis progression in patients with IHD was significantly associated with decrease in levels of both atherogenic lipids and C-reactive protein.

    Two hundred thirteen male police officers between 21 and 52 years of age volunteered to participate in a physical evaluation and conditioning program. Information concerning the physical fitness status and risk of coronary heart disease (CHD) of police officers were shown. Younger police officers (less than 30 years of age) were average in physical fitness levels and CHD risk compared to the population of the same age. Middle-aged police officers were shown to be lower in physical fitness levels and higher in CHD risk compared to their cohorts. The results from this investigation support the need for physical fitness and preventive medicine programs for police officers.

    Chronic dental infections, even of low intensity, may cause the development of atherosclerotic changes in arteries, that lead to coronary heart disease. There are many risk factors for atherosclerosis, but the most important are endothelium function disturbances, platelets activation and oxidative changes of plasmatic lipoproteins. Among factors that can induce the epithelium lesions bacterial factor may play an important role. In consequence of the bacterial cell breakdown place the release of endotoxins takes, that lead directly to the damage of endothelial cells. Apart from this direct effect endotoxins activate the fagocytes releasing superoxide reactive radicals, that cause lesions of endothelium. Probably the most widespread chronic bacterial infections in human are the diseases of periodontium and teeth and their inflammatory complications. Oral cavity is colonized by 300-400 bacterial species. In the case of dental bacterial infections bacteriemia occurs after such procedures as tooth extraction, endodontic treatment, therapeutic and hygienic interventions on periodontal tissues. The results of many investigations show the relationship between the oral status (dental and periodontal diseases as chronic oral infections) and disorders of cardiovascular system. PMID:17474623

    Full Text Available BACKGROUND: Recent clinical studies have suggested that γ-glutamyltransferase (γ-GT can trigger oxidative stress within the plaque. This study aimed to investigate whether serum γ-GT might be as a risk factor of coronary heart disease (CHD, and measure the associations of serum γ-GT with high sensitive C-Reactive Protein (hs-CRP, Oxidized LDL (Ox-LDL and Glutathione Peroxidase (GPx. METHODS: This study recruited 48 patients aged 30-70 year who underwent coronary angiography at Haji Adam Malik Medical Center at Medan between February and April 2008 and who presented at least one coronary stenosis of >50% of the luminar diameter. The sample subjects were consecutively selected. RESULTS: γ-Glutamyltransferase was positively associated (r=0.546 with hs-CRP as a marker of chronic inflammation after careful adjustment for other established risk factors in CHD patient. But, there was no significant difference between γ-GT in male and female patients. Further, there were no correlations between γ-GT and Ox-LDL and GPx. Ratio of γ-GT/GPx was measured as well, and it was associated with hs-CRP. CONCLUSIONS: Ratio of γ-GT/GPx was associated with inflammation process in coronary heart disease patients. KEYWORDS: γ-glutamyltransferase (γ-GT, inflammation, oxidative stress, coronary heart disease.

    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.

Objective: to study the incidence, pattern, and specific features of CHD in patients with RA. Patients and methods. An analytical cross-sectional study was conducted in 257 patients with RA (ARA, 1987. The patients’ mean age was 55.4±11.6 years; RA duration was 14.7years (range 2—20 years. Results. The incidence of CHD in RA was as much as 45.9% (n = 118, including 52.5% (n = 62 for typical angina pectoris on exertion; 25.4% (n = 30 and 22.1% (n = 26 for silent ischemia and arrhythmias, respectively. A high proportion of vertebrogenic cardialgias (48.8%; n = 100 were noted in those who complained of heart pain. The authors identified traditional risk factors, such as hypertension (OR = 12.1, smoking (OR = 10.2, early menopause (OR = 3.6, decreased glomerular filtration rate (OR = 3.5, cardiovascular heredity (OR = 3.1, overweight (OR = 2.5, a heart rate of more than 70 beats/min (OR = 2.3, atherogenic dyslipidemia (OR = 2.3, hyperglycemia (OR = 2.1, and age (OR = 1.7. Along with those, the authors also ascertained CHD predictors associating with chronic inflammation consequences: use of glucocorticoids (OR = 5.0, concomitant anemia as a common complication of RA (OR = 4.7, high DAS 28 scores (OR = 3.7, visual analog scale pain scores of > 50 mm (OR = 2.6, and RA duration of >10 years (OR = 2.2. Conclusion. The specific features of CHD in RA include the frequent detection of arrhythmias and silent ischemia. The importance of the degree of inflammatory activity along with the traditional risk factors of CHD is apparent.

    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.

The research design was quasi-experimental. Results: Results were considered significant at p value less than to equal to 0.0001 (p≤0.0001 and revealed that: Heart surgery decreased social adjustment but had no significant impact on heart inpatients' depression. Conclusion: After treatment, it was common for patients to exhibit behavior problems, depression, poor social adaptation and/or noncompliance with the medical regimen. The psychosocial adaptation of surgery procedure can be promoted through support and counseling by one or all members of the surgery team caring for the patients and their families. This process must start during the first visit to the treatment center.

    Objective Test the hypothesis that exercise training enhances sustained relaxation to persistent endothelium-dependent vasodilator exposure via increased nitric oxide contribution in small coronary arteries of control and ischemic hearts. Methods Yucatan swine were designated to a control group or a group in which an ameroid constrictor was placed around the proximal LCX. Subsequently, pigs from both groups were assigned to exercise (5 days/week; 16 weeks) or sedentary regimens. Coronary arteries (~100–350 μm) were isolated from control pigs and from both nonoccluded and collateral-dependent regions of chronically-occluded hearts. Results In arteries from control pigs, training significantly enhanced relaxation responses to increasing concentrations of bradykinin (10−10 to 10−7 M) and sustained relaxation to a single bradykinin concentration (30 nM), which were abolished by NOS inhibition. Training also significantly prolonged bradykinin-mediated relaxation in collateral-dependent arteries of occluded pigs, which was associated with more persistent increases in endothelial cellular Ca2+ levels, and reversed with NOS inhibition. Protein levels for eNOS and p-eNOS-(Ser1179), but not caveolin-1, Hsp90, or Akt, were significantly increased with occlusion, independent of training state. Conclusions Exercise training enhances sustained relaxation to endothelium-dependent agonist stimulation in small arteries of control and ischemic hearts by enhanced nitric oxide contribution and endothelial Ca2+ responses.

    Background: Chronic diseases, including coronary heart disease (CHD), have been associated with ingestion of drinking water with high levels of inorganic arsenic (> 1,000 μg/L). However, associations have been inconclusive in populations with lower levels (< 100 μg/L) of inorganic arsenic exposure. Objectives: We conducted a case-cohort study based on individual estimates of lifetime arsenic exposure to examine the relationship between chronic low-level arsenic exposure and risk of CHD. Methods: This study included 555 participants with 96 CHD events diagnosed between 1984 and 1998 for which individual lifetime arsenic exposure estimates were determined using data from structured interviews and secondary data sources to determine lifetime residence, which was linked to a geospatial model of arsenic concentrations in drinking water. These lifetime arsenic exposure estimates were correlated with historically collected urinary arsenic concentrations. A Cox proportional-hazards model with time-dependent CHD risk factors was used to assess the association between time-weighted average (TWA) lifetime exposure to low-level inorganic arsenic in drinking water and incident CHD. Results: We estimated a positive association between low-level inorganic arsenic exposure and CHD risk [hazard ratio (HR): = 1.38, 95% CI: 1.09, 1.78] per 15 μg/L while adjusting for age, sex, first-degree family history of CHD, and serum low-density lipoprotein levels. The risk of CHD increased monotonically with increasing TWAs for inorganic arsenic exposure in water relative to < 20 μg/L (HR = 1.2, 95% CI: 0.6, 2.2 for 20–30 μg/L; HR = 2.2; 95% CI: 1.2, 4.0 for 30–45 μg/L; and HR = 3, 95% CI: 1.1, 9.1 for 45–88 μg/L). Conclusions: Lifetime exposure to low-level inorganic arsenic in drinking water was associated with increased risk for CHD in this population.

    Backgrounds Catestatin is an endogenous multifunctional neuroendocrinepeptide. Recently, catestatin was discovered as a novel angiogenic cytokine. The study was to investigate the associations between endogenous catestatin and coronary collateral development among the patients with chronic myocardial ischemia. Methods Thirty-eight patients with coronary artery chronic total occlusions (CTO) (CTO group) and 38 patients with normal coronary arteries (normal group) were enrolled in the series. Among the patients with CTO, coronary collateral development was graded according to the Rentrop score method. Rentrop score 0–1 collateral development was regarded as poor collateral group and 2–3 collateral development was regarded as good collateral group. Plasma catestatin level and vascular endothelial growth factor (VEGF) were measured by ELISA kits. Results The plasma catestatin levels in CTO group were significantly higher than that in normal group (1.97±1.01 vs 1.36±0.97ng/ml, p = 0.009). In the CTO group, the patients with good collateral development had significantly higher catestatin and VEGF levels than those with poor collateral development (2.36±0.73 vs 1.61±1.12 ng/ml, p = 0.018; 425.23±140.10 vs 238.48±101.00pg/mL, pCTO. However, there is no correlations between plasma catestatin levels and VEGF (r = -0.06, p = 0.744). In the multiple linear regression models, plasma catestatin level was one of the independent factors of coronary collateral development after adjustment for confounders. Conclusions Plasma catestatin was associated with coronary collateral developments. It may be a useful biomarker for coronary collateral development and potential target for therapeutic angiogenesis in patients with CTO. PMID:27304618

    Full Text Available It is postulated that patients with ischaemic heart disease (IHD and coronary steal prone anatomy (CSPA may develop myocardial ischaemia under isoflurane anaesthesia. This study was conducted in 50 patients undergoing coronary artery bypass grafting. Among these 10 patients (20% had CSPA, as evidenced by coronary angiography. Anaesthesia was induced with fentanyl, midazolam and thiopentone and maintained with isoflurane in oxygen after endotracheal intubation. Patients were continuously monitored with automated ST segment analysis of electrocardiogram (ECG and transoesophageal echocardiography (TEE. The end-tidal concentration of isoflurane was maintained at 1.2%, which is equal to one minimum alveolar concentration. Haemodynamic parameters were maintained within 20% of baseline values with either the use of phenylephrine or increasing the depth of anaesthesia by using midazolam and fentanyl. ST changes were measured after 80 ms of J-point in ECG and TEE monitored for occurrence of new regional wall motion abnormalities during the study period. ST changes more than +/-1.0 mm were considered as an indication of myocardial ischaemia. Out of 10 patients having CSPA, 50% developed significant ECG changes during isoflurane anaesthesia at an endtidal concentration of 1.2%. In patients not having CSPA new ischaemia was not observed. Our study indicates necessity of close monitoring of patients with IHD and CSPA during isoflurane anaesthesia to identify new ischaemia and institute appropriate measures.

    Blood cell-cell and cell-vessel wall interactions are one of the key patterns in blood and vascular pathophysiology. We have chosen the method of reconstruction of pulsative blood flow in vitro in the experimental set. Blood flow structure was studied by PC integrated video camera with following slide by slide analysis. Studied flow was of constant volumetric blood flow velocity (1 ml/h). Diameter of tube in use was comparable with coronary arteries diameter. Glucose solution and unfractured heparin were used as the nonspecial irritants of studied flow. Erythrocytes space structure in flow differs in all groups of patients in our study (men with stable angina pectoris (SAP), myocardial infarction (MI) and practically healthy men (PHM). Intensity of erythrocytes aggregate formation was maximal in patients with SAP, but time of their "construction/deconstruction" at glucose injection was minimal. Phenomena of primary clotting formation in patients with SAP of high function class was reconstructed under experimental conditions. Heparin injection (10 000 ED) increased linear blood flow velocity both in patients with SAP, MI and PHP but modulated the cell profile in the flow. Received data correspond with results of animal model studies and noninvasive blood flow studies in human. Results of our study reveal differences in blood flow structure in patients with coronary heart disease and PHP under irritating conditions as the possible framework of metabolic model of coronary blood flow destabilization.

    Angiotensin II is important in the development of cardiovascular disease. In the present study, angiotensin II receptor mRNA levels were quantified by real-time polymerase chain reaction (real-time PCR) in human coronary arteries from patients with ischemic heart disease and controls. Furthermore......, the suitability of artery culture for studying angiotensin receptor changes was evaluated by in vitro pharmacology and real-time PCR. The angiotensin type 1 (AT1) receptor mRNA levels were down-regulated in human coronary arteries from patients with ischemic heart disease as compared to controls (P

    To compare the features of coronary computed tomography angiography (CCTA) imaging of the patients with acute total occlusion (ATO) of coronary artery with those of chronic total occlusion (CTO). CCTA of 26 patients with complete interruption of the coronary artery in CCTA and occlusion in conventional coronary angiography, were retrospectively analyzed. Discrimination between the ATO group (n = 11, patients with non ST elevation myocardial infarction or unstable angina) and the CTO group (n = 15, patients with stable angina or nonspecific symptom) was arbitrarily determined by clinical diagnosis. Lesion length, remodeling index (RI), plaque density measured by Hounsfield units (HU), plaque composition, percentage attenuation drop across the lesion, and presence of myocardial thinning were evaluated. Comparisons between the ATO and CTO groups revealed significantly shorter lesion length in the ATO group (0.40 cm vs. 1.87 cm, respectively; p = 0.001), and significantly higher RI (1.56 vs. 1.10, respectively; p = 0.004). Plaque density of the ATO group was lower (37.0 HU vs. 104.7 HU, respectively; p < 0.001) and non calcified plaque was frequently seen in the ATO group (72.7% vs. 26.7%, respectively; p = 0.02). Percentage attenuation drop across the lesion was lower for the ATO group (10.92% vs. 25.44%, respectively; p = 0.005). Myocardial thinning was exclusively observed in the CTO group (seven of 15 patients, p = 0.01). CCTA shows various statistically significant differences between the ATO and CTO groups.

    We highlight the presence of a calcified mass in the left main coronary artery without significant atherosclerosis seen in the other coronary arteries or in the peripheral large arteries. In our view, the calcified character of the obstruction and the calcification of the aortic valve are characteristic of a variant type of coronary artery disease (CAD) not associated with the same risk factors as diffuse coronary atherosclerosis, but, in this case, with rheumatic heart disease. This case rep...

  9. Increased serum iron associated with coronary heart disease among nigerian adults

    International Nuclear Information System (INIS)

    To examine the concentrations of serum iron and some risk factors of coronary heart disease in Nigerians with evidence of Coronary Heart Disease. The concentration of serum iron, the plasma cholesterol level, the hip-waist ratio and body mass index of 70 patients with evidence of CHD seen at a Cardiology Unit of a Specialist Hospital in Ibadan and 70 healthy subjects selected randomly were determined. Subjects were grouped into four age categories and three socioeconomic classes (high, middle and low). The age of the subjects ranged from 31-70 years with the mean of 53.6+-11.0 years and 50.1+-10.5 years for patients and controls respectively. The mean serum iron and plasma cholesterol levels were significantly higher among patients than controls irrespective of age and sex (p<0.05). No correlation was found between serum iron and the variables; plasma cholesterol level, age, body mass index (BMI) and hip-waist ratio. Significantly higher serum iron levels found in patients with evidence of CHD appears to support the hypothesis that there is a potential association between iron status and CHD. (author)

    Full Text Available Radiologically revealed spine osteoporosis in male with hypertension and coronary heart disease Objective. To study prevalence and intensity of spine osteoporosis (OP in men suffering from hypertension (H and coronary heart disease (CHD. Material and methods. 101 men with H and CHD aged 50 to 78 years (mean age 60,6±0,85 years and 37 men of control group without cardiovascular diseases aged 50-66 years (mean age 58,6±0,74 years were examined. Clinical examination, radiological, radiomorphometric spine examination and echocardioscopy were performed. Results. OP was revealed in 34,65% of main group pts what is 3,2 times more frequent than in control group (10,8%, p<0,05. OP intensity in men with H and CHD was significantly higher than in healthy people. Vfertebral fractures were revealed in 12,87+3,3% of main group pts and only in 2,7±2,7% in control group (p<0,05. OP development dependence from cardiac history duration and cardiac pathology severity was demonstrated. Conclusion. The results of the study show significantly higher prevalence of spine OP among men suffering from H and CHD. Long history and severity of cardiovascular pathology clinical signs promote OP frequency and severity increase.

    Objective Tobacco smoking results in increased platelet aggregability, which suggests that low-dose aspirin used in common clinical practice may not effectively inhibit platelet activity in smokers with coronary heart disease (CHD). This review was performed to assess the effect of aspirin on platelet aggregation in patients with CHD.Data sources We performed an electronic literature search of MEDLINE (starting from the beginning to March 15, 2009)using the term "smoking" or "tobacco" paired with the following: "platelet", "aspirin" or "coronary heart disease".Study selection We looked for review articles regarding the effect of tobacco smoking on platelet activity and on the anti-platelet efficacy of aspirin in healthy people and patients with CHD. The search was limited in "core clinical journal".In total, 1321 relevant articles were retrieved, and 36 articles were ultimately cited.Results Tobacco smoking results in increased platelet aggregability, which can be inhibited by low-dose aspirin in the healthy population. However, in patients with CHD, the increased platelet aggregability can not be effectively inhibited by the same low-dose of aspirin. A recent study indicated that clopidogrel or an increased dose of aspirin can effectively inhibit the increased platelet aggregability induced by tobacco smoking in patients with CHD.Conclusions It is important for patients with CHD to quit smoking. For the current smoker, it may be necessary to take larger doses of aspirin than normal or take an adenosine diphosphate receptor inhibitor along with aspirin to effectively inhibit the increased platelet activity.

    Abnormalities of the autonomic nervous system are known to be of prognostic significance in chronic heart failure (CHF). The prognostic value of positron emission tomography (PET) imaging of cardiac autonomic innervation in CHF has not been explored previously. We retrospectively studied the survival data of 46 NYHA class II-III CHF patients (mean LVEF 35%{+-}8%) who had undergone carbon-11 hydroxyephedrine ({sup 11}C-HED) studies at the Turku PET Centre between August 1992 and March 1996. The origin of CHF was dilated cardiomyopathy in 13 of the 46 patients and coronary artery disease with at least one prior myocardial infarction in the remaining 33. Data on causes of death and heart transplantation were collected, and the statistically significant predictors of prognosis were analysed using Cox's proportional hazards regression. During the mean follow-up period of 55{+-}19 months, 11 deaths occurred and two patients underwent heart transplantation successfully. Eleven end-points were classified as cardiac (nine sudden cardiac deaths and two deaths due to progressive heart failure) and two as non-cardiac. When divided into two groups based on the median of {sup 11}C-HED retention (mean 0.184{+-}0.061, median 0.183), eight end-points (death or cardiac transplantation) were reached in the group with {sup 11}C-HED retention below the median and three in the group with {sup 11}C-HED retention above the median (P<0.02). In proportional hazards regression analysis, only peak oxygen uptake (peak VO{sub 2}), left ventricular end-diastolic volume and HED retention were found to be statistically significant. It is concluded that {sup 11}C-HED PET provides independent prognostic information in patients with CHF. (orig.)

    Full Text Available Background: Data on premature coronary artery disease (CAD are scarce. The Tehran Heart Center's Premature Coronary Atherosclerosis Cohort Study (THC-PAC is the first study of its kind in the Middle East to assess major adverse cardiac events (MACE in young CAD patients.Methods: The cohort consists of CAD patients, males ≤ 45 years old and females ≤ 55 years old. The participants are residents of Tehran or its suburbs and underwent coronary angiography between June 2004 and July 2011. A 10-year follow-up, via either clinical visits or telephone calls at least once a year, was commenced in August 2012. The end point is considered MACE, encompassing death, myocardial infarction, stroke, new coronary involvement, percutaneous coronary intervention, and coronary artery bypass grafting.Results: The cohort comprises 1232 eligible patients (613 [49.8%] males at a mean age of 45.1 years (SD = 5.8. High frequencies of conventional risk factors, including hyperlipidemia (884 [71.8%], hypertension (575 [46.7%], positive family history (539 [43.8%], cigarette smoking (479 [38.8%], and diabetes mellitus (390 [31.7%], were seen in the participants. The mean body mass index (BMI of the enrolled patients was high (29.2 ± 4.8 kg/m2, and 532 (43.3% and 440 (35.8% of them were overweight and obese, respectively. The females’ BMI was higher (30.4 ± 5.3 vs. 28.0 ± 3.9 kg/m2; P < 0.001 and they had a greater mean abdominal circumference (99.9 ± 13.5 vs. 98.1 ± 9.3 cm; P = 0.035.

    Chronic insomnia is highly prevalent in the general population, provoking personal distress and increased risk for psychiatric and medical disorders. Autonomic hyper-arousal could be a pathogenic mechanism of chronic primary insomnia. The aim of this study was to investigate autonomic activity in patients with chronic primary insomnia by means of heart rate variability (HRV) analysis. Eighty-five consecutive patients affected by chronic primary insomnia were enrolled (38 men and 47 women; mean age: 53.2 ± 13.6). Patients were compared with a control group composed of 55 healthy participants matched for age and gender (23 men and 32 women; mean age: 54.2 ± 13.9). Patients underwent an insomnia study protocol that included subjective sleep evaluation, psychometric measures, and home-based polysomnography with evaluation of HRV in wake before sleep, in all sleep stages, and in wake after final awakening. Patients showed modifications of heart rate and HRV parameters, consistent with increased sympathetic activity, while awake before sleep and during Stage-2 non-REM sleep. No significant differences between insomniacs and controls could be detected during slow-wave sleep, REM sleep, and post-sleep wake. These results are consistent with the hypothesis that autonomic hyper-arousal is a major pathogenic mechanism in primary insomnia, and confirm that this condition is associated with an increased cardiovascular risk.

    Full Text Available Abstract Background Coronary heart disease and depression are both common health problems and by 2020 will be the two leading causes of disability worldwide. Depression has been found to be more common in patients with coronary heart disease but the nature of this relationship is uncertain. In the United Kingdom general practitioners are now being remunerated for case-finding for depression in patients with coronary heart disease, however it is unclear how general practitioners should manage these patients. We aim to explore the relationship between coronary heart disease and depression in a primary care population and to develop an intervention for patients with coronary heart disease and depression. Methods/design This programme of research will consist of 4 inter-related studies. A 4 year prospective cohort study of primary care patients with coronary heart disease will be conducted to explore the relationship between coronary heart disease and depression. Within this, a nested case-control biological study will investigate genetic and blood-biomarkers as predictors of depression in this sample. Two qualitative studies, one of patients' perspectives of treatments for coronary heart disease and co-morbid depression and one of primary care professionals' views on the management of patients with coronary heart disease and depression will inform the development of an intervention for this patient group. A feasibility study for a randomised controlled trial will then be conducted. Discussion This study will provide information on the relationship between coronary heart disease and depression that will allow health services to determine the efficiency of case-finding for depression in this patient group. The results of the cohort study will also provide information on risk factors for depression. The study will provide evidence on the efficacy and feasibility of a joint patient and professional led intervention and data necessary to plan a

    Chronic heart failure (CHF) is the leading cause of hospitalization for those over the age of 65 and represents a significant clinical and economic burden. About half of hospital re-admissions are related to co-morbidities, polypharmacy and disabilities associated with CHF. Moreover, CHF also has an enormous cost in terms of poor prognosis with an average one year mortality of 33%–35%. While more than half of patients with CHF are over 75 years, most clinical trials have included younger pati...
