    Coronary Artery Disease (CAD) risk increases with increasing number of risk factors. This study was aimed to assess different coronary risk factors among Coronary Artery Bypass Grafting (CABG) surgery patients. A total of 700 patients younger than 45 or older than 65 years and underwent CABG in Tabriz Shahid Madani Heart Center since 2003 to 2007 were enrolled. We examined the probable differences of CAD risk factors between male and female groups and age groups. We also assessed the change of risk factors presentation in last 5 years. There was not significant difference between risk factor numbers in 65 years groups, but smoking and dyslipidemia was more prevalent in patients 65 years old. Hypertension and diabetes mellitus was more prevalent in patients > 65 old than < 45 years old; also differences were found between males and females patients, so that dyslipidemia, diabetes and hypertension were more prevalent in women than men. Some risk factors were recognized as acting more on one gender than the other. Also, the majority of patients have one or more risk factors, but different age and gender groups may have different risk factors that suggest the need for exact programming for appropriate prophylactic and therapeutic interventions in all groups.

    This article reviews the risk factors of the coronariopathy in the newborn. The authors state that the early diagnosis of the risk factors is an important step in the prevention of ateromatous plaques. Some people are now in the investigation of the normal levels of cholesterol and triglicerides in the blood of the umbilical cord. This values seems similar in different places all over the world and have served to establish the possible interrelation between the newborn hiperlipidemia and the coronary risk.

    Postprandial hypertriglyceridemia is now established as an important risk factor for cardiovascular disease (CVD). This metabolic abnormality is principally initiated by overproduction and/or decreased catabolism of triglyceride-rich lipoproteins (TRLs) and is a consequence of predisposing genetic variations and medical conditions such as obesity and insulin resistance. Accumulation of TRLs in the postprandial state promotes the retention of remnant particles in the artery wall. Because of their size, most remnant particles cannot cross the endothelium as efficiently as smaller low-density lipoprotein (LDL) particles. However, since each remnant particle contains approximately 40 times more cholesterol compared with LDL, elevated levels of remnants may lead to accelerated atherosclerosis and CVD. The recognition of postprandial hypertriglyceridemia in the clinical setting has been severely hampered by technical difficulties and the lack of established clinical protocols for investigating postprandial lipemia. In addition, there are currently no internationally agreed management guidelines for this type of dyslipidemia. Here we review the mechanism for and consequences of excessive postprandial hypertriglyceridemia, epidemiological evidence in support of high triglycerides and remnant particles as risk factors for CVD, the definition of hypertriglyceridemia, methods to measure postprandial hypertriglyceridemia and apolipoproteins and, finally, current and future treatment opportunities.

    The authors investigated the extension of major coronary risk factors among metal-flatten workers. In the whole population the percentage of these factors was as follows: hypertension 14,4%, hypercholesterolemia, 17.7%, hyperglycemia 6,5%, overweight 35% and cigarette smoking 61,3%. The extension of the risk factors is dependent on age and increases with age. No significant correlation was found between these factors and working conditions. In comparison to other investigations carried out in Poland the examined population exhibited considerable tobacco smoking, overweight, hyperglycemia and hypercholesterolemia.

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

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

    More than one-half of young adults aged 18-24 y have at least 1 coronary heart disease (CHD) risk factor and nearly one-quarter have advanced atherosclerotic lesions. The extent of atherosclerosis is directly correlated with the number of risk factors. Unhealthy dietary choices made by this age group contribute to weight gain and dyslipidemia. Risk factor profiles in young adulthood strongly predict long-term CHD risk. Early detection is critical to identify individuals at risk and to promote lifestyle changes before disease progression occurs. Despite the presence of risk factors and pathological changes, risk assessment and disease prevention efforts are lacking in this age group. Most young adults are not screened and are unaware of their risk. This review provides pathological evidence along with current risk factor prevalence data to demonstrate the need for early detection. Eighty percent of heart disease is preventable through diet and lifestyle, and young adults are ideal targets for prevention efforts because they are in the process of establishing lifestyle habits, which track forward into adulthood. This review aims to establish the need for increased screening, risk assessment, education, and management in young adults. These essential screening efforts should include the assessment of all CHD risk factors and lifestyle habits (diet, exercise, and smoking), blood pressure, glucose, and body mass index in addition to the traditional lipid panel for effective long-term risk reduction.

    Full Text Available Coronary Artery Disease (CAD is becoming a major cause of morbidity & mortality burden in the developing world. Indians have been associated with a more severe form of CAD that has its onset at a younger age group with a male predominance. A prospective study was carried out to identify the risk factors and to know the emerging clinical profile in acute coronary syndrome (ACS including S T elevation & Non S T elevation myocardial infarction. We enrolled 200 consecutive patients with typical ECG changes & clinical history, admitted in emergency department from January 2009 to December 2009. A predefined Performa was completed in every patient with a detailed clinical history, physical examinations, and investigation studies. The clinical history revealed information about age, gender, risk factors, and modes of presentation and duration of symptoms. The details of physical examination including anthropometric data, vital signs and complete systemic evaluation were recorded. The regions of infarction and rhythm disturbances were also documented. Our study showed a significant male predominance with mean age being 56 years. Tobacco was identified as major risk factors (65% & obesity (BMI more than 25 is least common risk factor (13%.Patients had typical chest pain (94% and ECG showed anterior wall changes in54%. Forty percent patients developed complications, majority being arrhythmias (60% and least common is mechanical complication (2.5% Thus we conclude that ACS is more common in adult male with tobacco being major risk factors in our population.

    2003-01-01

    Objective To investigate the role of coronary artery spasm in the etiology of chest pain lacking significant coronary stenosis and to identify the clinical risk factors related to coronary artery spasm. Methods Two hundred and seventy five patients with chest pain, but without significant coronary artery stenosis underwent the intracoronary acetylcholine test. Coronary artery spasm was diagnosed while coronary artery stenosis increased to 90% and was accompanied by the usual chest pain with or without ischemic changes on electrocardiogram. Logistic regression was employed to investigate the relationships between coronary artery spasm and sex, age, hypertension, diabetes mellitus, smoking, hyperlipidemia and results of electrocardiographic treadmill stress test. Left ventricular ejection fraction and end diastolic pressure were compared between spasm group and non-spasm group. Results Coronary artery spasm was detected in 103 out of 271 patients, a rate of 38%. Logistic regression analysis showed that smoking and hyperlipidemia increased the relative risk of coronary artery spasm 4.2 times and 2.3 times, respectively. There was a significantly negative relationship between diabetes mellitus and coronary artery spasm. Furthermore, there was no coronary artery spasm detected in left ventricular ejection fraction and end diastolic pressure. Conclusions Coronary artery spasm was one of the important etiological factors for patients with chest pain but no coronary artery stenosis. Smoking and hyperlipidemia were the main clinical risk factors for coronary artery spasm.

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

    Full Text Available OBJECTIVES: To investigate the prevalence, extent, severity, and features of coronary artery lesions in stable patients with multiple cardiovascular risk factors. METHODS: Seventy-seven patients with more than 3 cardiovascular risk factors were suspected of having coronary artery disease. Patients with high-risk factors and 39 controls with no risk factors were enrolled in the study. The related risk factors included hypertension, impaired glucose tolerance, dyslipidemia, smoking history, and overweight. The characteristics of coronary lesions were identified and evaluated by 64-slice coronary computed tomography angiography. RESULTS: The incidence of coronary atherosclerosis was higher in the high-risk group than in the no-risk group. The involved branches of the coronary artery, the diffusivity of the lesion, the degree of stenosis, and the nature of the plaques were significantly more severe in the high-risk group compared with the no-risk group (all p < 0.05. CONCLUSION: Among stable individuals with high-risk factors, early coronary artery lesions are common and severe. Computed tomography has promising value for the early screening of coronary lesions.

    Although primary care physicians understand the importance of preventive services for patients with multiple risk factors (MRF) for coronary heart disease, physician intervention is limited. This study investigated (1) physicians' views of challenges faced in managing patients with MRF; (2) the counseling and management methods they utilize; and (3) possible strategies to enhance MRF intervention in the primary care setting. Two focus groups were conducted with primary care physicians from varying settings to gain insight into these issues noted above. Each group was co-facilitated by a physician and a behavioral scientist using a previously developed semistructured interview guide. The group discussions were tape recorded and subsequently transcribed. Transcripts were analyzed using the constant comparative method for analysis. Physicians are challenged by knowledge limitations (contribution of individual risk factors to overall risk); limited support (guidelines, materials, and staff); and logistic difficulties (organizational issues, time limitations). Their approach to MRF management tends to be highly individualized with an initial preference for lifestyle change interventions rather than prescription of medications with some qualifying circumstances. Physicians favored a serial rather than a parallel approach to MRF intervention, starting with behaviors that the patient perceives as a priority. Proposed solutions to current challenges emphasize physician education and the development of innovative approaches that include physician assistance and a team approach. Physicians are aware of and sensitive to the complexity of MRF management for their patients and themselves. However, future MRF interventions will require nonphysician staff involvement and increased systems support.

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

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

    Full Text Available Abstract To establish the prevalence of coronary risk in physical education students, and compare risk between the genders and the years of course. We evaluated 246 physical education students using RISKO questionnaire to determine eight risk factors: age, heredity, body weight, smoking, physical inactivity, hypercholesterolemia, hypertension and sex. Students had mean coronary risk score of 16.03 ± 3.52 points, rated "below-average risk." Men had significantly greater risk compared to women. No difference was found between the years of course. The prevalence of risk factors were heritability (58.37%, physical inactivity (32.65%, hypercholesterolemia (32.24%, overweight (27.35%, smoking (3.67% and hypertension (2.45%. The coronary risk of physical education students was rated as below average, being higher among men than women, and no difference in risk between years of course. The most prevalent risk factors were heredity, physical inactivity, overweight and hypercholesterolemia.

    Traditional cardiovascular risk factors have been shown to cause microvascular dysfunction. Most studies that have evaluated microcirculation rely on invasive measurement tools. We used dobutamine stress echocardiography, a validated method to measure coronary flow velocity (CFV) and coronary flow reserve (CFR), in a previously unstudied population without known significant coronary artery disease to determine the impact of traditional risk factors on CFR. Consecutive patients who had no evidence of regional wall motion abnormalities at rest or during dobutamine stress echocardiography were studied. Left anterior descending artery CFV was measured at baseline and at peak dobutamine stress and CFR was calculated as the ratio of peak stress CFV to baseline CFV. Fifty-nine consecutive patients (28 men) with mean age of 66.8+/-14.5 years were studied. CFR was lower in patients with diabetes mellitus (DM) compared with those without (1.7+/-0.74 vs 2.48+/-0.98, p50 mm Hg), and obesity with a wide pulse pressure. In a multivariate model, DM, obesity, and wide pulse pressure were significantly associated with variation in CFR (p<0.0008). In conclusion, CFR was abnormal in patients with DM, hypertension, and obesity. CFR impairment is exaggerated as the number of risk factors increases. Despite a negative dobutamine stress echocardiographic result, aggressive risk factor assessment and control should be implemented in patients with coronary risk factors due to an underlying abnormal CFR.

    Background Among patients with coronary artery disease (CAD), 80%–90% present at least one conventional risk factor. On the other hand, lipid profile modification after a cardiovascular event related to acute coronary syndrome (ACS) has been recognized. The prevalence of conventional risk factors and the lipid profile at the time of admission in patients with ACS and significant CAD (stenosis ≥50%) determined through coronary angiography is not well described. Methods We studied 3,447 patients with a diagnosis of ACS and significant CAD with stenosis ≥50%, as shown o n angiography. We recorded the presence of conventional risk factors, including smoking, hypertension, dyslipidemia, and diabetes. In addition, we analyzed the lipid profiles within the first 24 hours of admission. We analyzed the studied population and compared findings according to sex. Results Most patients (81.7%) were male. ST-elevation myocardial infarction was present in 51.3% of patients, and non-ST-elevation acute coronary syndrome was present in 48.7%. The most frequent risk factor was smoking, which was present in 68% of patients, followed by hypertension (57.8%), dyslipidemia (47.5%), and diabetes (37.7%). In women, the most frequent risk factors were hypertension, diabetes, and dyslipidemia, whereas in men, smoking was the most frequent. We identified at least one risk factor in 95.7% of all patients, two or three risk factors in 62%, and four risk factors in 8.6% of patients. The lipid profile analysis revealed that 85.1% of patients had some type of dyslipidemia, and the most frequent was low levels of high-density lipoprotein cholesterol (68.6% of cases). Conclusion We found at least one conventional risk factor in 95.7% of patients with ACS and significant CAD. The lipid profile analysis revealed that two thirds of cases had low high-density lipoprotein cholesterol levels. PMID:25328397

On the other hand, lipid profile modification after a cardiovascular event related to acute coronary syndrome (ACS has been recognized. The prevalence of conventional risk factors and the lipid profile at the time of admission in patients with ACS and significant CAD (stenosis ≥50% determined through coronary angiography is not well described. Methods: We studied 3,447 patients with a diagnosis of ACS and significant CAD with stenosis ≥50%, as shown on angiography. We recorded the presence of conventional risk factors, including smoking, hypertension, dyslipidemia, and diabetes. In addition, we analyzed the lipid profiles within the first 24 hours of admission. We analyzed the studied population and compared findings according to sex.Results: Most patients (81.7% were male. ST-elevation myocardial infarction was present in 51.3% of patients, and non-ST-elevation acute coronary syndrome was present in 48.7%. The most frequent risk factor was smoking, which was present in 68% of patients, followed by hypertension (57.8%, dyslipidemia (47.5%, and diabetes (37.7%. In women, the most frequent risk factors were hypertension, diabetes, and dyslipidemia, whereas in men, smoking was the most frequent. We identified at least one risk factor in 95.7% of all patients, two or three risk factors in 62%, and four risk factors in 8.6% of patients. The lipid profile analysis revealed that

    To investigate risk factors for coronary atherosclerosis in men and women in the recent general Japanese population, we examined coronary arteries obtained from subjects autopsied in the Hisayama cohort study (autopsy rate: 78.7%). The subjects were over 40 years of age and consisted of 125 men and 108 women. They underwent an antemortem medical examination in 1988 and were subject to autopsy at death during an 8-year follow-up period. Atherosclerosis was globally assessed by examining 14 specimens taken from wide areas of epicardial coronary arteries and classified into 6 grades. The frequency of more severe grades of coronary atherosclerosis increased with age in both genders and was greater in men than in women of the same age. Multiple regression analysis revealed that age, systolic blood pressure, serum total cholesterol, and hemoglobin A(1C) were significant risk factors for men. Age, systolic blood pressure, and waist to hip ratio were risk factors for women. Smoking was not significantly correlated with the grade of coronary atherosclerosis in either gender. Thus, aging, hypertension, hypercholesterolemia, obesity, and glucose intolerance are risk factors for coronary atherosclerosis in recent Japanese populations, and the significance of the metabolic risk factors is different between men and women.

    2015-03-01

    Full Text Available INTRODUCTION : Cardiovascular disease is the commonest cause of death globally. Acute myocardial infarction generally occurs when coronary blood flow decreases abruptly after thrombotic occlusion of a coronary artery causing focal or massive necrosis of cardiac muscle. The risk factor concept implies that a person with one risk factor is more likely to develop clinical atherosclerotic event and is more likely to do so earlier than a person with no risk factors. The presence of multiple risk factors further accelerates th e atherosclerosis. Hence it is important to identify the major risk factors of coronary atherosclerosis in an individual with acute myocardial infarction so that further preventive measures can be taken in the form of lifestyle modification and pharmacothe rapy. MATERIALS AND METHODOLOGY: T his is a hospital based study. This study comprises of 100 cases of acute myocardial infarction admitted in ICCU under the department of medicine and 100 normal healthy controls in the age group of 29 - 85 years. Patients wi th the evidence of acute MI were diagnosed according to WHO criteria. Blood samples collected in vacutainers were analyzed for different biochemical parameters in the clinical biochemistry laboratory. RESULTS: Common risk factors have been evaluated in our study and we found that maximum MI patients were recorded in the age group of 51 - 60 years, with respect to other risk factors history like sex, majority of patients were males (82%, Sedentary life style (44%, Mixed dietary habits (84%, Family history o f IHD (6%, Dyslipidemia and Smoking (46%, Hypertension (31%, Diabetes (37%, Obesity (18%. In our study we found that 81% of the patients of acute MI had multiple risk factors. CONCLUSION: Thus from the study we can conclude that risk factors play a ma jor role in the genesis of coronary heart disease. Modification of these factors by pharmacotherapy, diet, physical exercises and behavioral therapy can improve the

    Full Text Available Background: evidence provided by the Framingham Heart Study established the critical role of risk factors in the development of coronary heart disease. Over half a century later, current detection and control are still inadequate. Objective: to identify modifiable risk factors of coronary heart disease in individuals aged 20 to 49 years. Methods: a descriptive, cross-sectional study was conducted in 276 individuals from the doctor’s office No. 1 of the Fabio di Celmo Community Teaching Polyclinic in Cienfuegos. Patients were examined in the clinic visit and/or whole family visit. The studied variables included age, sex, skin color, risk factors (excess weight/obesity, physical inactivity, smoking, hypertension, diabetes, dyslipidemia and psychosocial factors, which were obtained from the medical interview, physical examination, laboratory tests (total cholesterol and triglycerides and review of individual medical records and family history. Results: risk factors most frequently identified were excess weight/obesity (42.4 %, physical inactivity (34.4 % and smoking (20.3 %. Presence of these risk factors increased with age, showing differences in the distribution by sex and was associated with psychosocial factors. Their coexistence and progress with age was significant. Conclusion: prevalence of modifiable risk factors for coronary heart disease in a young population was high, with frequent association, predominating factors related to unhealthy lifestyles.

    In this study we aimed to analyse the frequency of atherosclerotic risk factors with focus to novel risk factors for coronary artery disease and angiographic profile in young (≤ 40 years) acute coronary syndrome (ACS) patient with healthy controls in Gujarat, India. Between January 2008 and December 2012, 109 consecutive young patients aged ≤ 40 years old, diagnosed to have ACS were included in the study. All ACS patients underwent diagnostic coronary angiography. An equivalent age and sex matched population without coronary disease with similar risk factors without tobacco considered a control group. All angiographic patients were evaluated for conventional risk factors for coronary artery disease like diabetes mellitus, hypertension, smoking, obesity as well as novel atherogenic risk factors like high sensitivity C-reactive protein (Hs-CRP), Lipoprotein(a) [LP(a)], homocysteine, apolipoprotein A1 (ApoA1) and B (ApoB). In a study group, out of 109 young patients, 90 (82.6%) patients were presented to our hospital as ST-segment elevation myocardial infarction (STEMI), 10 (9.2%) presented as known non-ST-elevation myocardial infarction (NSTEMI) and 9 (8.3%) presented as unstable angina (UA). Serum cholesterol, triglycerides, LDL, LP(a) and lipid tetrad index were significantly higher in the study group whereas the HDL levels significantly lower as compared to the control group. A quite common risk factors of premature CAD are smoking, high Hs-CRP, high LP(a), hyperhomocysteinaemia and positive family history in the young ACS. Most common presentation of ACS in young was STEMI. On angiography, single vessel involvement was the most common finding.

    Since the introduction of the Framingham Risk Score (FRS), numerous versions of coronary heart disease (CHD) prediction models have claimed improvement over the FRS. Tzoulaki et al challenged the validity of these claims by illustrating methodology deficiencies among the studies. However, the question remains: Is it possible to create a new CHD model that is better than FRS while overcoming the noted deficiencies? To address this, a new CHD prediction model was developed by integrating additional risk factors, using a novel modeling process. Using the National Health Nutritional Examination Survey III data set with CHD-specific mortality outcomes and the Atherosclerosis Risk in Communities data set with CHD incidence outcomes, two FRSs (FRSv1 from 1998 and FRSv2 from National Cholesterol Education Program Adult Treatment Panel III), along with an additional risk score in which the high density lipoprotein (HDL) component of FRSv1 was ignored (FRSHDL), were compared with a new CHD model (NEW-CHD). This new model contains seven elements: the original Framingham equation, FRSv1, and six additional risk factors. Discrimination, calibration, and reclassification improvements all were assessed among models. Discrimination was improved for NEW-CHD in both cohorts when compared with FRSv1 and FRSv2 (Prisk assessment when compared with the FRSs, comparable to the improvement of adding HDL to the FRS.

    Full Text Available AIM To study the clinical profile of coronary artery disease in women and to identify the influence of the risk factors. METHODS We conducted a prospective observational study in Vydehi Institute of Medical Science and Research Centre (VIMS & RC, Bengaluru during the period June 2012 to Dec 2013. Patients admitted with history suggestive of coronary artery disease were evaluated clinically and investigated for risk factors. Prognosis with regards to morbidity and mortality following the standard treatment protocol was documented. RESULTS Out of 100 cases of coronary artery disease (CAD, 32 had Acute Myocardial infarction (AMI, 23 with Unstable Angina and 45 patients had Stable Angina. Nearly half of the patients had the traditional risk factors, namely hypertension (HTN, diabetes mellitus (DM, hyperlipidaemia and obesity. Chest pain was the most common symptom. Mortality was 14% which was observed predominantly in post-menopausal women who presented after 24 hours of the onset of symptoms. CONCLUSION Coronary artery disease is no longer a disease of men. Men and women share the same traditional risk factors like HTN, DM, Obesity, and Hyperlipidaemia. Increased incidence of complications and mortality occurred in those who presented after 24 hours of the symptoms. Our study highlights the importance of early recognition of CAD and initiation of thrombolytic therapy, to reduce significant morbidity and mortality.

    With a decade earlier manifestation of coronary artery disease (CAD) and paucity of data characterizing coronary plaque with coronary computed tomography angiography (CTA) among CAD patients in India, the study aimed to analyze patient characteristics and coronary plaque burden and morphology in young Indian patients with CAD. Serial coronary CTA was performed in 96 CAD patients. Among 60 patients ≤40years, risk factor and coronary plaque analysis done using a 256- slice CT in 33 patients with acute coronary syndrome (ACS) was compared with 27 patients with chronic stable angina (CSA). Univariate and multivariate analysis was performed, for factors predicting ACS as an outcome among young CAD patients. In addition, quantitative and morphologic plaque characteristics were compared among those ≤40years and >40years. Among 60 subjects ≤40years of age, 77% had dyslipidemia, 70% high lipoprotein(a), 53.33% elevated hs-CRP and 73.33% raised homocysteine. hs-CRP (9.33 vs. 3.33, p value=0.01) and serum triglycerides (178.67 vs. 141.42, p value=0.03) were markedly raised in patients with ACS. Statistically significant number of patients in the ACS group had positive remodelling (ACS, 69.7% vs. CSA, 14.8%; p value30mg/dL and composite vulnerability score maintained a predictive value for ACS in patients ≤40years. Statistically significant number of patients in the younger age group had higher mean total plaque volume (66.17±41.31mm(3) vs. 44.94±49.07mm(3); p=0.03), remodelling index (1.5±0.27 vs. 1.08±0.38; p=0.0001). Comparing culprit lesion characteristics of ACS patients in the two age groups, positive remodelling (95.8% vs. 70.5%, p=0.02), spotty calcification (50% vs. 11.7%, p=0.01) and non-calcified plaque (95.8% vs. 70.5%, p=0.02) were significantly more frequent in patients ≤40years. ACS in young Indians is characterized by a higher prevalence of both conventional and newer risk factors. In addition, culprit lesions in young ACS patients are more

    Full Text Available Abstract Background The purpose of the present study was to evaluate the mechanical properties of coronary plaques and plaque behavior, and to elucidate the relationship among tissue characteristics of coronary plaques, mechanical properties and coronary risk factors using integrated backscatter intravascular ultrasound (IB-IVUS. Methods Non-targeted plaques with moderate stenosis (plaque burden at the minimal lumen site: 50-70% located proximal to the site of the percutaneous coronary intervention target lesions were evaluated by IB-IVUS. Thirty-six plaques (less calcified group: an arc of calcification ≤10° in 36 patients and 22 plaques (moderately calcified group: 10°  Results In the less calcified group, there was a significant correlation between EEMV compliance and the relative lipid volume (r = 0.456, p = 0.005. There was a significant inverse correlation between EEM area stiffness index and the relative lipid volume (p = 0.032, r = −0.358. The LV compliance and EEM area stiffness index were significantly different in the diabetes mellitus (DM group than in the non-DM group (1.32 ± 1.49 vs. 2.47 ± 1.79%/10 mmHg, p =0.014 and 28.3 ± 26.0 vs. 15.7 ± 17.2, p =0.020. The EEMV compliance and EEM area stiffness index were significantly different in the hypertension (HTN group than in the non-HTN group (0.77 ± 0.68 vs. 1.57 ± 0.95%/10 mmHg, p =0.012 and 26.5 ± 24.3 vs. 13.0 ± 16.7, p =0.020. These relationships were not seen in the moderately calcified group. Conclusion The present study provided new findings that there was a significant correlation between mechanical properties and tissue characteristics of coronary arteries. In addition, our results suggested that the EEMV compliance and the LV compliance were independent and the compliance was significantly impaired in the patients with DM and/or HTN. Assessment of coronary mechanical properties during PCI may provide us with

    A strong relationship is known to exist between coronary artery disease (CAD) and coronary artery calcification (CAC) detected by CT. In this study, we investigated the frequency of CAC and the relationship between coronary risk factors, CAD and CAC in a mass screening using a mobile helical CT unit. The total number of participants was 10008 people undergoing a medical examination for lung cancer and tuberculosis using a mobile helical CT unit. We measured the CT density of the coronary artery to detect CAC. The CT density threshold for determining CAC was above +110HU. The frequency of CAC was 16.0% in the overall patient population and significantly higher in males than in females (20.6% vs 10.7%). Frequency increased with age in both genders. Hypertension and diabetes mellitus were significantly related to CAC. Smoking showed a correlation with CAC only in males. A significant relationship was observed between CAD and CAC in males. In particular, the relationship between them was strongest in males under 60 years of age. Furthermore, the odds ratio of CAC in predicting CAD increased with increasing risk factors in both genders.

    Full Text Available Spontaneous coronary artery dissection (SCAD is a rare cause of acute myocardial infarction that is more common in younger patients (under age 50 and in women. Although the etiology is not known, some predisposing conditions to SCAD are well known and include Marfan syndrome, pregnancy and peripartum state, drug abuse, and some anatomical abnormalities of the coronary arteries such as aneurysms and severe kinking. We describe a case of SCAD in a young woman who presented with sudden onset of chest pain and was admitted for the treatment of acute coronary syndrome. The coronary angiography showed dissection of the left anterior descending artery. The patient underwent successful percutaneous transluminal coronary angioplasty and stent placement.

    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.

    Full Text Available Background: It is predicted that cardiovascular diseases will be the most important cause of mortality in India by the year 2015. Since the key to combating the increased incidence of coronary artery disease (CAD is the control of known risk factors by a population based strategy aimed at comprehensive risk reduction, it is pertinent to study the magnitude of the risk. Aim: The present study was therefore conducted to assess the prevalence of certain coronary risk factors among rural population aged 35 years and above in Maharashtra. Methods: The present community based cross sectional survey was carried out in the rural area of Pune district on 272 subjects using a structured questionnaire, clinical examination followed by lab investigations. SPSS version 17.0 was used for analysis. Results: Tobacco consumption was found to be prevalent in 51.83% of the study subjects followed by physical inactivity which was prevalent among 31.61% whereas high diastolic blood pressure was found to be prevalent in 29.41% of the study subjects. Obesity and alcohol consumption were found to be prevalent among 13.97% of the study subjects. Among the biochemical parameters studied, hypertriglyceridemia was found to be prevalent in 22.05% followed by raised fasting blood sugar in 15.44% of the study subjects. Conclusion: Behaviour change communication strategies targeting these modifiable known high risk factors need to be emphasized to lower coronary heart disease (CHD related morbidity burden in the community.

    The EUROASPIRE audits of risk factor control have indicated that, even in those with established coronary heart disease, risk factor control remains poor. We therefore analysed the EUROASPRE III data set to establish the factors associated with success or failure in risk factor control in order to inform future risk factor management strategies. University education, attendance at a specialist cardiology clinic, and participation in a cardiac rehabilitation programme were associated with improved risk factor control. Risk factor control was poorer in women, those with diabetes, and those undergoing coronary artery bypass surgery as opposed to medical therapy or percutaneous coronary intervention. Increasing age, depression, and anxiety were not associated with poorer risk factor control.

    Objective To compare patients without previously diagnosed cardiovascular risk factors) and patients with one or more risk factors admitted with acute coronary syndrome. Methods This was a retrospective analysis of patients admitted with first episode of acute coronary syndrome without previous heart disease, who were included in a national acute coronary syndrome registry. The patients were divided according to the number of risk factors, as follows: 0 risk factor (G0), 1 or 2 risk factors (G1 - 2) and 3 or more risk factors (G ≥ 3). Comparative analysis was performed between the three groups, and independent predictors of cardiac arrest and death were studied. Results A total of 5,518 patients were studied, of which 72.2% were male and the mean age was 64 ± 14 years. G0 had a greater incidence of ST-segment elevation myocardial infarction, with the left anterior descending artery being the most frequently involved vessel, and a lower prevalence of multivessel disease. Even though G0 had a lower Killip class (96% in Killip I; p < 0.001) and higher ejection fraction (G0 56 ± 10% versus G1 - 2 and G ≥ 3 53 ± 12%; p = 0.024) on admission, there was a significant higher incidence of cardiac arrest. Multivariate analysis identified the absence of risk factors as an independent predictor of cardiac arrest (OR 2.78; p = 0.019). Hospital mortality was slightly higher in G0, although this difference was not significant. By Cox regression analysis, the number of risk factors was found not to be associated with mortality. Predictors of death at 1 year follow up included age (OR 1.05; p < 0.001), ST-segment elevation myocardial infarction (OR 1.94; p = 0.003) and ejection fraction < 50% (OR 2.34; p < 0.001). Conclusion Even though the group without risk factors was composed of younger patients with fewer comorbidities, better left ventricular function and less extensive coronary disease, the absence of risk factors was an independent predictor of cardiac arrest.

    Full Text Available Contrast induced nephropathy (CIN is one of important complication of contrast media administration. Its incidence and risk factors among Indonesian patients undergoing coronary intervention has not been reported yet. CIN was defined as increasing of serum creatinine by 0.5 mg/dl or more in the third day following contrast media exposure. Of 312 patients undergoing coronary intervention, 25% developed CIN. Patient-related risk factors comprised of hypertension, diabetes mellitus, NYHA class, proteinuria, serum creatinine > 1.5 mg/dl and ejection fraction ≤ 35%. Contrast-related risk factors comprised of contrast media volume > 300 ml, contrast media type. However, our final model demonstrated that only hypertension [Hazard ratio (HR = 2.89, 95% confidence intrval (CI = 1.78 to 4.71, P = 0.000], diabetes mellitus (HR = 3.09, 95% CI = 1.89 to 5.06, P = 0.000, ejection fraction (EF ≤ 35% (HR = 2.92; 95% CI = 1.72 to 4.96; P = 0.000, total contrast volume > 300 ml (HR = 7.73; 95% CI = 3.09 to 19.37; P = 0.000 and proteinuria (HR = 14.96; 95% CI = 3.45 to 64.86; P = 0.000 were independent risk factors of CIN. In conclusion, CIN developed in 25% of patients undergoing coronary intervention. The independent risk factors of CIN included hypertension, diabetes mellitus, EF ≤ 35%, contrast volume > 300 ml and proteinuria.

    Full Text Available Abstract Objective The influence hemostatitc parameters on the morphological extent and severity of coronary artery disease were studied in patients with and without DM type 2. Background It is known that patients with diabetes (DM have abnormal metabolic and hemostatic parameters Methods Of 150 consecutive patients with angiographically proven coronary artery disease 29 presented with DM. Additionally to parameters of lipid-metabolism fibrinogen, tissue-plasminogenactivator (t-PA, plasminogen-activator-inhibitor (PAI, plasmin-a-antiplasmin (PAP, prothrombin-fragment 1+2 (F1+2, thrombin-antithrombin (TAT, von-willebrand-factor (vWF, platelet factor 4 (PF4, glykomembranproteine 140 (GMP140 and the rheologic parameters plasma viscosity and red blood cell aggregation were evaluated. The extent and severity of CAD was evaluated according to the criteria of the American Heart Association. Results Patients with DM presented with a higher number of conventional risk factors as compared to non-diabetic patients. Additionally there were significant differences for F1+2, red blood cell aggregation and PAI. Diabetic patients showed a more severe extent of coronary arteriosclerosis, which also could be found more distally. A significant relationship between blood-glucose, thrombocyte-activation (vWF, endogenous fibrinolysis (PAI and the severity of CAD and a more distal location of stenoses could be found (r = 0.6, p Conclusion Patients with coronary artery disease and DM type 2 showed marked alterations of metabolic, hemostatic, fibrinolytic and rheologic parameters, which can produce a prothrombogenic state. A direct association of thrombogenic factors on coronary morphology could be shown. This can be the pathophysiologic mechanism of more severe and distal pronounced coronary atherosclerosis in these patients.

    Full Text Available Guizhou Hu,1 Martin Root,2 Ashlee W Duncan1 1BioSignia, Inc., Durham, NC, USA; 2Department of Nutrition and Health Care Management, Appalachian State University, Boone, NC, USA Purpose: Since the introduction of the Framingham Risk Score (FRS, numerous versions of coronary heart disease (CHD prediction models have claimed improvement over the FRS. Tzoulaki et al challenged the validity of these claims by illustrating methodology deficiencies among the studies. However, the question remains: Is it possible to create a new CHD model that is better than FRS while overcoming the noted deficiencies? To address this, a new CHD prediction model was developed by integrating additional risk factors, using a novel modeling process. Methods: Using the National Health Nutritional Examination Survey III data set with CHD-specific mortality outcomes and the Atherosclerosis Risk in Communities data set with CHD incidence outcomes, two FRSs (FRSv1 from 1998 and FRSv2 from National Cholesterol Education Program Adult Treatment Panel III, along with an additional risk score in which the high density lipoprotein (HDL component of FRSv1 was ignored (FRSHDL, were compared with a new CHD model (NEW-CHD. This new model contains seven elements: the original Framingham equation, FRSv1, and six additional risk factors. Discrimination, calibration, and reclassification improvements all were assessed among models. Results: Discrimination was improved for NEW-CHD in both cohorts when compared with FRSv1 and FRSv2 (P<0.05 and was similar in magnitude to the improvement of FRSv1 over FRSHDL. NEW-CHD had a similar calibration to FRSv2 and was improved over FRSv1. Net reclassification for NEW-CHD was substantially improved over both FRSv1 and FRSv2, for both cohorts, and was similar in magnitude to the improvement of FRSv1 over FRSHDL. Conclusion: While overcoming several methodology deficiencies reported by earlier authors, the NEW-CHD model improved CHD risk assessment when

Coronary artery disease (CAD is a complex, multifactorial disease in which personality seems to play a role but with no definition in combination with other risk factors. Objective. To explore the nonlinear and simultaneous pathways between traditional and personality traits risk factors and coronary stenosis by Artificial Neural Networks (ANN data mining analysis. Method. Seventy-five subjects were examined for traditional cardiac risk factors and personality traits. Analyses were based on a new data mining method using a particular artificial adaptive system, the autocontractive map (AutoCM. Results. Several traditional Cardiovascular Risk Factors (CRF present significant relations with coronary artery plaque (CAP presence or severity. Moreover, anger turns out to be the main factor of personality for CAP in connection with numbers of traditional risk factors. Hidden connection map showed that anger, hostility, and the Type D personality subscale social inhibition are the core factors related to the traditional cardiovascular risk factors (CRF specifically by hypertension. Discussion. This study shows a nonlinear and simultaneous pathway between traditional risk factors and personality traits associated with coronary stenosis in CAD patients without history of cardiovascular disease. In particular, anger seems to be the main personality factor for CAP in addition to traditional risk factors.

    Full Text Available Sergi Sayols-Baixeras, Carla Lluís-Ganella, Gavin Lucas, Roberto ElosuaCardiovascular Epidemiology and Genetics Research Group, Institut Hospital del Mar d'Investigacions Mèdiques, Barcelona, SpainAbstract: Coronary artery disease (CAD is the leading cause of death and disability worldwide, and its prevalence is expected to increase in the coming years. CAD events are caused by the interplay of genetic and environmental factors, the effects of which are mainly mediated through cardiovascular risk factors. The techniques used to study the genetic basis of these diseases have evolved from linkage studies to candidate gene studies and genome-wide association studies. Linkage studies have been able to identify genetic variants associated with monogenic diseases, whereas genome-wide association studies have been more successful in determining genetic variants associated with complex diseases. Currently, genome-wide association studies have identified approximately 40 loci that explain 6% of the heritability of CAD. The application of this knowledge to clinical practice is challenging, but can be achieved using various strategies, such as genetic variants to identify new therapeutic targets, personal genetic information to improve disease risk prediction, and pharmacogenomics. The main aim of this narrative review is to provide a general overview of our current understanding of the genetics of coronary artery disease and its potential clinical utility.Keywords: coronary artery disease, pathogenesis, genetic risk factors, genetic variants

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

In the study, 687 patients admitted for coronary angiography to investigate suspected coronary artery disease and 994 individuals representing the Hungarian population were enrolled. The patients were classified according to the presence of significant coronary atherosclerosis (CAS and history of myocardial infarction (MI. The F13B gene was genotyped for p.His95Arg and for intron K nt29756 C>G polymorphisms; the latter results in the replacement of 10 C-terminal amino acids by 25 novel amino acids. The p.His95Arg polymorphism did not influence the risk of CAS or MI. The FXIII-B intron K nt29756 G allele provided significant protection against CAS and MI in patients with a fibrinogen level in the upper tertile. However, this effect prevailed only in the presence of the FXIII-A Leu34 allele, and a synergism between the two polymorphisms was revealed. Carriers of the intron K nt29756 G allele had significantly lower FXIII levels, and FXIII levels in the lower tertile provided significant protection against MI. It is suggested that the protective effect of the combined polymorphisms is related to decreased FXIII levels.

    Coronary heart disease (CHD) is one of the major causes of disability in adults as well as one of the main causes of death in the developed countries. Although significant progress has been made in the diagnosis and treatment of CHD, further investigation is still needed. The objective of this study was to develop a data-mining system for the assessment of heart event-related risk factors targeting in the reduction of CHD events. The risk factors investigated were: 1) before the event: a) nonmodifiable-age, sex, and family history for premature CHD, b) modifiable-smoking before the event, history of hypertension, and history of diabetes; and 2) after the event: modifiable-smoking after the event, systolic blood pressure, diastolic blood pressure, total cholesterol, high-density lipoprotein, low-density lipoprotein, triglycerides, and glucose. The events investigated were: myocardial infarction (MI), percutaneous coronary intervention (PCI), and coronary artery bypass graft surgery (CABG). A total of 528 cases were collected from the Paphos district in Cyprus, most of them with more than one event. Data-mining analysis was carried out using the C4.5 decision tree algorithm for the aforementioned three events using five different splitting criteria. The most important risk factors, as extracted from the classification rules analysis were: 1) for MI, age, smoking, and history of hypertension; 2) for PCI, family history, history of hypertension, and history of diabetes; and 3) for CABG, age, history of hypertension, and smoking. Most of these risk factors were also extracted by other investigators. The highest percentages of correct classifications achieved were 66%, 75%, and 75% for the MI, PCI, and CABG models, respectively. It is anticipated that data mining could help in the identification of high and low risk subgroups of subjects, a decisive factor for the selection of therapy, i.e., medical or surgical. However, further investigation with larger datasets is

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

    Prevention of coronary heart disease (CHD) is the most effective way in fighting with epidemic of this illness in our country. Risk factors of CHD are divided into modifying and non-modifying. General knowledge of cardiac risk factors in young population is the most important point in prophylactic. Our aim was to elucidate knowledge of cardiovascular disease risk factors in students. We distributed a questionnaire to 544 students (264 women and 280 men) of 3 Universities in Warsaw in the middle age 22 +/- 0.79. The survey contained 22 answers: general risk factors (obesity--O, high cholesterol level--Ch, smoking--S. hypertension--HA, wrong diet--D, family history--F, life style--S, age--A, diabetes--DM, male--M, down limbs arteriosclerosis--DLA, myocardial infarction in family under 55 years old-MI) and wrong answers (allergic, female, mobile phone...). Data were taken under analyze. Right risk factors were mentioned by the following number of students: O--92%, Ch--89%, S--85%, HA--75.8%, D--71%, F--65.2%, DM--50.4%, M--49.3%. DLA--36.9%, MI--36.0%. General knowledge of modifying cardiac risk factors, not including diabetes, is high among polish students. However, the knowledge is poor about non-modifying factors, like gender, age, early MI in family. The results of our study let us hope that the students will correctly use their knowledge to reduce risk of CHD in their families.

    To understand when women's coronary heart disease (CHD) and CHD risk factors are recognized prior to first myocardial infarction (MI). Medical record review of the 10 years prior to incident MI among women with a confirmed incident MI between January 1, 1996, and December 31, 2001, to determine the timing of CHD diagnosis as well as assessment and treatment for risk factors. One hundred fifty women had incident MIs during the study period. They made 8732 ambulatory visits and had 457 hospitalizations during the period of review (mean 9.1 years, range 6.2-10 years). Average age at incident MI was 74.7 years (SD 12.6, range 38.9-99.8 years). A CHD diagnosis prior to first MI was present in 52% (n = 78) of the women but was less common in those <70 years (p = 0.001). All but 3 women had one or more modifiable risk factors identified prior to their first MI. Treatment of recognized risk factors varied from 81% (antihypertension medications) to only 28% (drug therapy for abnormal lipid levels). Having a diagnosis of CHD was associated with an increased likelihood of having identified risk factors and receiving drug treatment for identified risk factors. Women with undiagnosed CHD (48%) and those with unrecognized or untreated risk factors for CHD, especially younger women, represent missed opportunities for prevention of cardiac events.

    Full Text Available Background. Cardiometabolic risk factors significantly accelerate the progression of coronary artery disease (CAD; however, whether CAD patients in South China are aware of the prevalence of these risk factors is not clear yet. Methods. The study consisted of 2312 in-admission CAD patients from 2008 to 2011 in South China. Disease history including hypertension, dyslipidemia, and diabetes was relied on patients' self-reported records. Physical and clinical examinations were tested to assess the real prevalence of the cardiometabolic risk factors. Results. 57.9% of CAD patients had more than 3 cardiometabolic risk factors in terms of the metabolic syndrome. The self-known and real prevalence of hypertension, diabetes, and dyslipidemia were 56.6%, 28.3%, and 25.1% and 91.3%, 40.9%, and 92.0%, respectively. The awareness rates were 64.4%, 66.3%, and 28.5% for hypertension, diabetes, and dyslipidemia. The prevalence of cardiometabolic risk factors was significantly different among gender and among disease status. Conclusions. Most CAD patients in South China had more than three cardiometabolic risk factors. However, the awareness rate of cardiometabolic diseases was low, especially for dyslipidemia. Strategies of routine physical examination programs are needed for the early detection and treatment of cardiometabolic risk factors in order to prevent CAD progression and prognosis.

We sought to study the prevalence and coexistence of 6 cardiovascular risk factors (RFs among patients who underwent percutaneous coronary intervention (PCI, and to evaluate the impact of age and gender on the presence of multiple RFs. Methods and results. In this prospective, multicenter study, 2426 consecutive patients were enrolled. Mean age was 59.0 ± 10.1 years and 500 (20.6% were women. Acute coronary syndrome and stable coronary disease were the indications for PCI in 77.1% and 22.9%, respectively. Hypertension was present in 62.3%, diabetes in 53.8%, hypercholesterolemia in 48.8%, smoking in 43.5%, family history of premature CVD 39.4% and obesity in 28.8%. Only 3.8% did not have any of these RFs. Presence of ⩾3 and ⩾4 RFS was observed in 57.4% and 29.5% of patients, respectively. Presence of ⩾3 RFs was more common in women than men (69.0% vs. 54.5%, p < 0.0001, and among patients 41–65 years of age than older or younger patients (60.1% vs. 52.0% vs. 48.3%, respectively, p = 0.017. Conclusions: Cardiovascular RFs are highly prevalent in this PCI Middle Eastern population undergoing PCI. More than half and more than one-fourth of the patients had at least 3 or 4 RFs; respectively. More women than men and more middle aged patients than older or younger patients had significantly higher rates of presence of multiple RFs.

    Lipoprotein-associated phospholipase A2 (Lp-PLA₂) is at the crossroads of lipid metabolism and the inflammatory response. It is produced by inflammatory cells, bound to LDL and other lipoproteins, and once in the arterial wall facilitates hydrolysis of phospholipids. Elevated serum levels of Lp-PLA₂ have been associated with increased cardiovascular risk in healthy populations and in patients with known vascular disease. Here, we review the role of Lp-PLA₂ in the development of atherosclerosis and progression to unstable disease, the utility of Lp-PLA₂ as a risk predictor for coronary and carotid events and the potential clinical benefit of pharmacologic inhibition of Lp-PLA₂.

    ABO blood type locus has been reported to have ethnic difference and to be a pivotal genetic determinant of cardiovascular risk, whereas few prospective data regarding the impact on cardiovascular outcomes are available in a large cohort of patients with angiography-proven coronary artery disease, especially from the Chinese population. The objective of this study was to assess the prognostic role of blood type in future cardiovascular events (CVEs) in Chinese Han patients undergoing coronary angiography.The population of this prospective cohort study consisted of 3823 eligible patients, and followed annually to capture all CVEs. Baseline characteristics and ABO blood type were obtained. Cox proportional hazards models were used to evaluate the risk of ABO blood type on CVEs.New CVEs occurred in 348 patients [263 (10.3%) non-O and 85 (7.8%) O] during a median period of 24.6 months follow-up. Significantly, non-O blood group was related to the presence and severity of coronary atherosclerosis and several risk factors including inflammatory markers. The log-rank test revealed that there was a significant difference between non-O and O blood groups in event-free survival analysis (P = 0.026). In particular, the Cox proportional hazards models revealed that non-O blood type was associated with increased CVEs risk [hazard ratio (95% confidence interval) 1.320 (1.033-1.685)], even after adjusting for potential confounders [adjusted hazard ratio (95% confidence interval) non-O: 1.289 (1.003-1.656); A: 1.083 (0.797-1.472); B: 1.481 (1.122-1.955); AB: 1.249 (0.852-1.831), respectively].Non-O blood type is associated with future CVEs in Chinese Han patients undergoing coronary angiography.

    Full Text Available Background. Social and behavioral risk markers (e.g., physical activity, diet, smoking, and socioeconomic position cluster; however, little is known whether clustering is associated with coronary heart disease (CHD risk. Objectives were to determine if sociobehavioral clustering is associated with biological CHD risk factors (total cholesterol, HDL cholesterol, systolic blood pressure, body mass index, waist circumference, and diabetes and whether associations are independent of individual clustering components. Methods. Participants included 4,305 males and 4,673 females aged ≥20 years from NHANES 2001–2004. Sociobehavioral Risk Marker Index (SRI included a summary score of physical activity, fruit/vegetable consumption, smoking, and educational attainment. Regression analyses evaluated associations of SRI with aforementioned biological CHD risk factors. Receiver operator curve analyses assessed independent predictive ability of SRI. Results. Healthful clustering (SRI = 0 was associated with improved biological CHD risk factor levels in 5 of 6 risk factors in females and 2 of 6 risk factors in males. Adding SRI to models containing age, race, and individual SRI components did not improve C-statistics. Conclusions. Findings suggest that healthful sociobehavioral risk marker clustering is associated with favorable CHD risk factor levels, particularly in females. These findings should inform social ecological interventions that consider health impacts of addressing social and behavioral risk factors.

    Family history (FH) provides insights into the effects of shared genomic susceptibilities, environments and behaviors, making it a potentially valuable risk assessment tool for chronic diseases. We assessed whether coronary heart disease (CHD) risk assessment is improved when FH information is added to other clinical information recommended in guidelines. We applied logistic regression analyses to cross-sectional data originally obtained from a UK study of women who delivered a live-born infant between 1951 and 1970. We developed 3 models: Model 1 included only the covariates in a guideline applicable to the population, Model 2 added FH to Model 1, and Model 3 included a fuller range of risk factors. For each model, its ability to discriminate between study subjects with and those without CHD was evaluated and its impact on risk classification examined using the net reclassification index. FH was an independent risk factor for CHD (odds ratio = 1.7, 95% confidence interval = 1.26-2.47) and improved discrimination beyond guideline-defined clinical factors (p risk factor for CHD, it added little to risk factors typically included in guidelines. © 2013 S.

    Full Text Available Abstract Background In Brazil coronary heart disease (CHD constitutes the most important cause of death in both sexes in all the regions of the country and interestingly, the difference between the sexes in the CHD mortality rates is one of the smallest in the world because of high rates among women. Since a question has been raised about whether or how the incidence of several CHD risk factors differs between the sexes in Brazil the prevalence of various risk factors for CHD such as high blood cholesterol, diabetes mellitus, hypertension, obesity, sedentary lifestyle and cigarette smoking was compared between the sexes in a Brazilian population; also the relationships between blood cholesterol and the other risk factors were evaluated. Results The population presented high frequencies of all the risk factors evaluated. High blood cholesterol (CHOL and hypertension were more prevalent among women as compared to men. Hypertension, diabetes and smoking showed equal or higher prevalence in women in pre-menopausal ages as compared to men. Obesity and physical inactivity were equally prevalent in both sexes respectively in the postmenopausal age group and at all ages. CHOL was associated with BMI, sex, age, hypertension and physical inactivity. Conclusions In this population the high prevalence of the CHD risk factors indicated that there is an urgent need for its control; the higher or equal prevalences of several risk factors in women could in part explain the high rates of mortality from CHD in females as compared to males.

    Full Text Available Abstract Background The prevalence of Coronary Atherosclerotic Heart Disease (CASHD is increasing in India. Several modifiable risk factors contribute directly to this disease burden. Public knowledge of such risk factors among the urban Indian population is largely unknown. This investigation attempts to quantify knowledge of modifiable risk factors of CASHD as sampled among an Indian population at a large metropolitan hospital. Methods A hospital-based, cross sectional study was conducted at All India Institute of Medical Sciences (AIIMS, a major tertiary care hospital in New Delhi, India. Participants (n = 217 recruited from patient waiting areas in the emergency room were provided with standardized questionnaires to assess their knowledge of modifiable risk factors of CASHD. The risk factors specifically included smoking, hypertension, elevated cholesterol levels, diabetes mellitus and obesity. Identifying 3 or less risk factors was regarded as a poor knowledge level, whereas identifying 4 or more risk factors was regarded as a good knowledge level. A multiple logistic regression model was used to isolate independent demographic markers predictive of a participant's level of knowledge. Results 41% of the sample surveyed had a good level of knowledge. 68%, 72%, 73% and 57% of the population identified smoking, obesity, hypertension, and high cholesterol correctly, respectively. 30% identified diabetes mellitus as a modifiable risk factor of CASHD. In multiple logistic regression analysis independent demographic predictors of a good knowledge level with a statistically significant (p Conclusion An Indian population in a hospital setting shows a lack of knowledge pertaining to modifiable risk factors of CASHD. By isolating demographic predictors of poor knowledge, such as current smokers and persons who do not exercise regularly, educational interventions can be effectively targeted and implemented as primary and secondary prevention strategies

    2009-01-01

    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.

    Full Text Available Background: Coronary artery disease is considered as the most common cause of death in all societies including Iran. This study seeks to compare the new risk factors of coronary-artery diseases in obese adolescents and control group. Methods: In this cross-sectional study, amongst the obese adolescents registered in the nutrition clinic of Ghaem Hospital, 80 individuals were selected. As the control group, additional 80 adolescent students having the same gender and age as the obese group, but with normal weight were selected. These two groups were selected randomly and their serum level of vitamin D, anti-heat shock protein27 (HSP27, balance of oxidants and antioxidants, and homocysteine were determined and compared. Results: In this study, 42 (53.2% and 37 (46.8% of the obese and normal weight groups were male, respectively. The mean value of triglyceride, cholesterol, and LDL in the obese group was higher than the normal group, but the mean value for HDL, vitamin D, homocysteine, PAB (Preoxidant and Antioxidants Balance, and anti-HSP27 was not significantly different between the groups. In the base of homocysteine >15 µmol/l, 26.6% of the obese group had hyperhomocysteinemia, therefore homocysteine may be a new risk factor for coronary artery disease in obese adolescents (χ2=4.072; P value=0.091. Conclusion: The findings of this study showed that despite the presence of obesity in adolescence and adolescents, new risk factors are not present among them more than the control group. This was in contrast to what was seen in adults.

    Full Text Available Background: The relationship between diet and cardiovascular risk factors in men and women with Coronary Artery Disease (CAD has been the subject of recent studies. We studied a group of Iranian CAD patients to analyze any relationship between diet and CAD risk factors based on gender. Methods: In this study, 461 consecutive patients were assessed before their planned isolated coronary artery bypass graft surgery. They were interviewed to obtain the quantity and components of nutrients and micronutrients based on a validated food frequency questionnaire. Diet scores were calculated in each dietary group and the total score was reported as the Mediterranean Diet Quality Index (Med-DQI. Physical activity was assessed using International Physical Activity Questionnaire (IPAQ. Functional class, EuroSCORE and the frequency of the known risk factors in the men and women were recorded as well. Results: The women were more likely than the men to present with obesity, diabetes mellitus, hypercholesterolemia, and hypertension (all Ps < 0.001. Also, the women had higher functional class and mean of EuroSCORE (P < 0.001 and P = 0.03. Only six women (5.7% reported to have regular physical activity. In addition, Women’s energy intake was more likely to be supplied through fat. Cereals, fruit, and vegetable consumption in both genders was within the safe recommended range, while olive and fish consumption was low in both sexes. MedDQI score was different between men and women with hypertension (P = 0.018 and obesity (P = 0.048. Conclusions: Modifiable classical risk factors for CAD, except for smoking, were more prevalent in women and were associated with their diet. Therefore, women probably need to maintain low calorie intake while improving physical activity and dietary patterns to decrease the frequency and severity of modifiable cardiac risk factors.

So this study was designed to investigate whether there is an association between ABO blood groups and cardiovascular risk factors in otherwise healthy people. Materials and Methods: In this cross-sectional study, risk factors for CVD were screened in 300 patients with coronary artery disease (CAD who were hospitalized in Madani hospital (biggest heart center in Tabriz in 2013-2014 and evaluated by a questionnaire that aimed to extract information about age, sex, smoking, blood group type, weight, height, blood pressure, diabetes mellitus and family history of CVD. Data were analyzed with SPSS 17. Results: Of the total selected 300 patients, 69.3% were male, 35.3% were smoker, 61% were hypertensive, 30.3% were diabetic mellitus, 31% had hyperlipidemia, 70.97% were obese and 17.3% had family history of CVD. The mean age was 62.06 ± 11.40 years. Blood groups O (28%, A (43.3%, B (19% and AB (7.3% were the most frequent ones, respectively. According to our results, we found that the rate of CAD in individuals with the blood group A was higher than the other blood groups. Regarding the risk factors, however, no significant difference was observed between the blood groups. Conclusion: A correlation was found between blood group A and the incidence of CAD and there was no significant difference between the blood groups and cardiovascular risk factors and number of involved coronary arteries.

    Dual therapy (aspirin and clopidogrel) increases the risk of upper gastrointestinal bleeding (UGIB). Acute coronary syndrome (ACS), a critical ill condition, may increase the risk of UGIB due to stress-related mucosal disease and the impact of receiving dual antiplatelet agents. We identified risk factors of UGIB in patients with coronary artery disease (CAD) receiving dual therapy. Patients who received dual therapy due to ACS or postpercutaneous coronary intervention (elective, primary, or urgent) were enrolled retrospectively. We assessed the occurrence of UGIB and identified the risk factors for UGIB at early stage (dual therapy ≤ 2 weeks) and late stage (> 2 weeks) by Cox regression analysis. During a mean follow-up period of 125 days, 67 (12.5 %) out of 534 patients developed UGIB (32 patients at early stage, 35 patients at late stage). Cox regression analysis showed that use of proton pump inhibitor therapy has a protective role in these patients [hazard ratio (HR): 0.10, 95% confidence interval (CI): 0.01-0.71]. ACS (HR: 2.67, 95% CI: 1.33-5.34) has a high risk of developing UGIB at an early stage. Old age (>75 years of age) (HR: 2.13, 95% CI: 1.02-4.47) and prior history of peptic ulcer disease (HR: 3.27, 95% CI: 1.28-8.34) each have an associated high risk for developing UGIB at a late stage. The use of mechanical ventilation (HR: 5.85, 95% CI: 2.19-15.58) also increased UGIB risk at both the early and late stages. ACS and mechanical ventilation are important risk factors of UGIB at the early stage (≤ 2 weeks). Additionally, old age (>75 years), past peptic ulcer disease history, and the use of mechanical ventilation play important roles in the occurrence of UGIB at late stage (>2 weeks). However, it was also noted that use of PPI plays a protective role in patients with CAD receiving aspirin and clopidogrel therapy. Copyright © 2012. Published by Elsevier B.V.

    It has been suggested that osteoporosis and coronary artery disease (CAD) have overlapping pathophysiological mechanisms and related risk factors. The aim of this study was to investigate the association between several traditional cardiovascular risk factors and measures of bone mineral density (BMD) in postmenopausal women with and without clinically significant CAD defined angiographically. A case-control study was undertaken of 180 postmenopausal women (aged between 48 and 88 years) who were recruited from King Abdulaziz University Hospital, Saudi Arabia. Study subjects underwent dual-energy x-ray absorptiometry and coronary angiography. The presence of hypertension, diabetes, dyslipidemia, obesity, smoking and physical activity was identified from clinical examination and history. Demographic, anthropometric and biochemical characteristics were measured. Univariate and multivariate analyses were employed to explore the relationships between cardiovascular risk factors, including BMD, and the presence of CAD. CAD patients were more likely to have a lower BMD and T-score at the femoral neck than those without CAD (P<0.05). Significant differences were found between the groups for fasting lipid profile, fasting blood glucose and anthropometric measures (P<0.05). Conditional logistic regression showed that 3 risk factors were significantly related with the presence of CAD: high-density lipoprotein-cholesterol (odds ratio, OR: 0.226, 95% confidence interval, CI: 0.062-0.826), fasting plasma glucose (OR: 1.154, 95% CI: 1.042-1.278) and femoral neck T-score (OR: 0.545, 95% CI: 0.374-0.794). This study suggests an association of low BMD and elevated CAD risk. Nevertheless, additional longitudinal studies are needed to determine the temporal sequence of this association.

    No previous study has investigated the predictive risk factors of the nursing diagnosis of risk for decreased cardiac output after coronary artery bypass grafting (CABG). This study aimed to identify the predictive risk factors of the nursing diagnosis of risk for decreased cardiac output after CABG. This was a prospective cohort study performed at a cardiac university hospital in São Paulo, Brazil and 257 adult patients undergoing CABG were included. Potential risk factors for low cardiac output in the immediate post-operative period were investigated using the patients' medical records. Univariate analysis and logistic regression were used to identify the predictive risk factors of decreased cardiac output. The area under the receiver operating characteristic curve was calculated as a measure of accuracy. The variables that could not be analysed through logistic regression were analysed through Fisher's exact test. One hundred and ninety-five patients had low cardiac output in the immediate post-operative period. The predictive risk factors included age ⩾60 years, decreased left ventricle ejection fraction, not using the radial artery graft, positive fluid balance and post-operative arrhythmia that differed from the pre-operative arrhythmia. This model predicted the outcome with a sensitivity of 62.9%, a specificity of 87.2% and an accuracy of 81.5%. The variables analysed through Fisher's exact test included heart failure, re-exploration and bleeding-related re-exploration. The predictive risk factors for the nursing diagnosis of risk for decreased cardiac output after CABG were found. These results can be used to direct nurses in patient monitoring, staff training and nursing team staffing.

    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.

    The prevalence of aortic valve calcification (AVC), strongly influenced by ethnicity, is unknown in Mexican population. The aim of this study was to investigate the prevalence of AVC and its associations with cardiovascular risk factors and coronary artery calcification (CAC), in Mexican subjects. In 1,267 subjects (53% women) without known coronary heart disease, aged 35 to 75 years, AVC and CAC were assessed by multidetector-computed tomography using the Agatston score. Cardiovascular risk factors were documented in all participants. The associations of AVC with CAC and risk factors were assessed by multivariable logistic regression analyses. The overall prevalence of AVC and CAC was 19.89% and 26.5%, respectively. AVC and CAC increased with age and were found more frequently in men (25.5% and 37.1%, respectively) than in women (14.9% and 13.0%, respectively). AVC was observed in only 8.5% of subjects without CAC, while those with CAC 1-99, 100-399, and >400 Agatston units had AVC prevalences of 36.8%, 56.8%, and 84.0%, respectively. The multivariable logistic regression analyses, adjusted for age, gender, obesity, physical inactivity, hypertension, dyslipidemia and high insulin levels, showed that the presence of CAC (OR [CI95%]: 3.23 [2.26-4.60]), obesity (1.94 [1.35-2.79]), male gender (1.44 [1.01-2.05]) and age (1.08 [1.03-1.10]), were significant independent predictors of AVC. Prevalence of AVC is high and significantly associated with atherosclerotic risk factors and CAC in this Mexican population. Copyright © 2016 Instituto Nacional de Cardiología Ignacio Chávez.

    Kennedy Space Center (KSC) employees are reported to be at high risk for coronary heart disease (CHD). Risk factors for CHD include high serum total cholesterol levels, low levels of high-density lipoprotein cholesterol (HDLC), elevated triglyceride, smoking, inactivity, high blood pressure, being male, and being older. Higher dietary and/or serum calcium Ca(++) may be related to a lower risk for CHD. Fifty men and 37 women participated. Subjects were tested in the morning after fasting 12 hours. Information relative to smoking and exercise habits was obtained; seated blood pressures were measured; and blood drawn. KCS men had higher risk values than KCS women as related to HDLC, triglycerides, systolic blood pressure, and diastolic blood pressure. Smoking and nonsmoking groups did not differ for other risk factors or for serum Ca(++) levels. Exercise and sedentary groups differed in total cholesterol and triglyceride levels. Serum Ca(++) levels were related to age, increasing with age in the sedentary group and decreasing in the exercisers, equally for men and women. It is concluded that these relationships may be significant to the risk of CHD and/or the risk of bone demineralization in an aging population.

    Nowadays, Cardiovascular Diseases (CVDs) represents an escalating worldwide public health problem. Providing consistent data on the magnitude and risk factors of CVDs among young population will help in controlling the risks and avoiding their consequences. The objective was to estimate the prevalence of risk factors of Coronary Heart Disease (CHD) among medical students during their clinical clerkship (4th - 6th years). A cross-sectional study was done during the educational year 2012-2013 at King Abdulaziz University (KAU), Jeddah. Ethical standards were followed and a multistage stratified random sample method was used for selection of 214 medical students. Data was collected through an interviewing questionnaire, measurements and laboratory investigations. Both descriptive and analytical statistics were done by SPSS version 21. CHD risk percent in thirty years was calculated using Framingham algorithm for each student, then the risk among all students was determined. The commonest risk factors of CHDs were daily intake of high fat diet (73.4%), physical inactivity (57.9%), overweight/or obesity (31.2%) and daily consumption of fast food (13.1%). Hyper-cholesterolemia (17.2%) and hypertension (9.3%) were also prevalent risk factors. Smoking prevalence was low (2.8%). Males had significantly higher mean scores for most of CHD risk factors compared to females (p < 0.05). Systolic Blood pressure was higher among males (119.47 ± 11.17) compared to females (112.26 ± 9.06). A highly statistical significant difference was present (Students't test = 4.74, p < 0.001). Framingham Risk Score revealed that CHD risk percent in thirty-years among all students was 10.7%, 2.3% and 0.5% for mild, moderate and severe risk, respectively. An alarmingly high prevalence of CHD risk factors was prevailed among medical students, especially among males. However, a low prevalence of smoking may indicate the success of "Smoke-free Campus" program. Screening risk

    Coronary heart disease (CHD) is the leading cause of death in Malaysia, despite its status as a developing country. The rural population is thought to be at low risk. To investigate the prevalence of risk factors and global risk profile among rural Malays in Malaysia. We studied 609 rural Malay subjects (346 females, 263 males; age range 30-65 years). Blood pressure (BP), body mass index (BMI), waist-hip ratio (WHR), smoking habits and family history of premature CHD were documented. Fasting blood samples were analysed for serum lipids, lipoprotein (a), plasma glucose and fibrinogen. Oral glucose tolerance tests were performed using 75 g anhydrous glucose. The prevalence of hypercholesterolaemia for total cholesterol concentrations of > or = 5.2, > or =6.5 and > or =7.8 mmol/l were 67.3, 30.5 and 11.8% respectively. There was a high prevalence of low serum high-density lipoprotein cholesterol (13.1%), hypertension (30.3%), smokers (24.4%), diabetes (6.4%), impaired fasting glucose or glucose tolerance (13.9%), overweight or obesity (44.7%) and increased WHR (48.5%). Global risk assessment showed that 67.3% of the study population were at risk, with 15.9, 18.9 and 32.5% in the mild, moderate and high risk categories respectively. Prevalence of risk factors was high in the rural population. Global risk assessment showed a high-risk profile with two-thirds being at risk, and one-third being categorized into the high-risk group. Although rural communities were considered at low risk of developing CHD, this is changing fast, possibly due to the rapid socio-economic development, in addition to underlying genetic predisposition.

    Full Text Available Abstract Background Coronary artery disease (CAD is a leading cause of mortality, morbidity, and disability with high health care cost in Iran. It accounts for nearly 50 percent of all deaths per year. Yet little is known about CAD and CAD risk factors in the Iranian population. We aimed to assess the prevalence of different CAD risk factors in an Iranian population. Methods A descriptive cross sectional survey was conducted involving 3000 healthy adults at 18 years of age or above who were recruited with cluster random sampling. Demographic data and risk factors were determined by taking history, physical examination and laboratory tests. Results The average age was 36.23 ± 15.26. There was 1381 female (46% and 1619 male (54% out of which 6.3% were diabetic, 21.6% were smoker, and 15% had positive familial heart disease history. 61% had total cholesterol level > 200 mg/dL, 32% triglyceride > 200 mg/dl, 47.5% LDL-c > 130 mg/dl, 5.4% HDL-c 140 mmHg, 9.1% diastolic blood pressure > 90 mmHg and 87% of them were physically inactive. Conclusion Clinical and Para-clinical data indicated that Iranian adult population are of a high level of CAD risk factors, which may require urgent decision making to address national control measures regarding CAD.

    Although numerous risk factors have been established to predict the development of acute coronary syndrome (ACS), the risk factor profile may be different between the younger and older individuals. To analyse the frequency and pattern of atherogenic risk factors and angiographic profiles in age-stratified Gujarati patients with ACS. ACS patients undergoing coronary angiography at U.N. Mehta Institute of Cardiology and Research, Gujarat, India between January 2008 and December 2012 were classified in to two age groups with 40y as cut-off. Patients were assessed for conventional risk factors (diabetes mellitus, dyslipidaemia, hypertension, smoking, obesity), novel risk factors (high sensitivity C-reactive protein, lipoprotein (a), homocysteine), and angiographic profiles.The statistical difference between two age groups was determined by Student's t-test for continuous variables and Chi-square or Fisher's exact test for categorical variables. A total of 200 patients, 100 patients ≤40 y of age and 100 patients >40 y of age, were evaluated. Older patients had higher frequency of hypertension (32 vs. 16%, p=0.008), while family history of coronary artery disease was more common among younger patients (19 vs. 9%, p=0.041). The incidence of diabetes, dyslipidaemia, smoking and tobacco chewing did not vary significantly between the two groups. Total cholesterol and low-density lipoprotein cholesterol levels were significantly higher in the younger group (p<0.05). Lipoprotein (a), homocysteine and high-sensitivity C reactive protein levels were comparable between two age groups. Multi-vessel coronary artery disease was more common among older group. The most commonly affected coronary artery was the left anterior descending artery among younger patients (44%) and the left circumflex artery among older patients (38.1%). Young patients with ACS had different atherosclerotic risk profile and less extensive coronary artery disease as compared to older counterparts. Emphasis

    To investigate the incidence rate and the risk factors for postoperative cognitive dysfunction (POCD) in patients underwent coronary artery bypass grafting surgery. A total of 147 patients underwent elective coronary artery bypass grafting (CABG) surgery between January to July 2013 were included in this study. POCD was diagnosed using a neuropsychological test battery. All enrolled patients were interviewed on the day before surgery, the seventh day and 3 months after surgery, respectively, by the same researcher, and were divided into two groups based on the results: the POCD group and the non-POCD group. The information, including age, sex, body mass index, educational status, comorbidities, history of smoking and drinking, ASA grade, left ventricular ejection fraction, operation method, duration of operations, regional cerebral oxygen saturation, the lowest haemoglobin concentrations and the haemoglobin concentration decline rate during the operation, tracheal catheter retention time, postoperative pain on visual analogue scales (VAS) and systemic inflammatory response syndrome score (SIRS score), were recorded based on a schedule of survey. Multivariate logistic regression was used to analyze the risk factors for POCD. A total of 101 patients finished this study. On 7 days and 3 months after surgery, 38 and 21 cases showed POCD, with an incidence rate at 37.6% and 20.8%, respectively. Interestingly, there was no significant difference in incidence of POCD between CABG and OPCABG group on both 7 days and 3 months after surgery (P>0.05). The logistic stepwise regression analysis indicated that the risk factors for POCD included advanced age (OR=1.177, 95%CI 1.071-1.292, P=0.001), the haemoglobin concentration decline rate (OR=1.334, 95%CI 1.152-1.545, PSIRS score (OR=2.815, 95%CI 1.014-7.818, P=0.047). The incidence rate of POCD was 37.6% and 20.8% on 7 days and 3 months after surgery respectively. Advanced age, the haemoglobin concentration decline rate and

    The aim of this study is to examine the prevalence of coronary heart disease (CHD)-related disability (hereafter also "disability") and the impact of CHD risk factors on disability in older adults in the Republic of Ireland (ROI) and Northern Ireland (NI). Population attributable fractions were calculated using risk factor relative risks and disability prevalence derived from The Irish Longitudinal Study on Ageing and the Northern Ireland Health Survey. Disability was significantly lower in ROI (4.1% vs. 8.8%). Smoking and diabetes prevalence rates, and the fraction of disability that could be attributed to smoking (ROI: 6.6%; NI: 6.1%), obesity (ROI: 13.8%; NI: 11.3%), and diabetes (ROI: 6.2%; NI: 7.2%), were comparable in both countries. Physical inactivity (31.3% vs. 54.8%) and depression (10.2% vs. 17.6%) were lower in ROI. Disability attributable to depression (ROI: 16.3%; NI: 25.2%) and physical inactivity (ROI: 27.5%; NI: 39.9%) was lower in ROI. Country-specific similarities and differences in the prevalence of disability and associated risk factors will inform public health and social care policy in both countries.

    Percutaneous coronary intervention (PCI) is often performed therapeutically, and antithrombotic treatment is required for at least 12 months after stent implantation. However, the development of post-PCI upper gastrointestinal bleeding (UGIB) increases morbidity and mortality. We investigated the incidence and risk factors for UGIB in Korean patients within 1 year after PCI. The medical records of 3,541 patients who had undergone PCI between January 2006 and June 2012 were retrospectively reviewed. We identified 40 cases of UGIB. We analyzed the incidence and clinical risk factors associated with UGIB occurring within 1 year after PCI by comparing the results for each case to matched controls. The propensity score matching method using age and sex was utilized. UGIB occurred in 40 patients (1.1%). Two independent risk factors for UGIB were a history of peptic ulcer disease (odds ratio [OR], 12.68; 95% confidence interval [CI], 2.70 to 59.66; p=0.001) and the use of anticoagulants (OR, 7.76; 95% CI, 2.10 to 28.66; p=0.002). UGIB after PCI occurred at a rate of 1.1% in the study population. Clinicians must remain vigilant for the possibility of UGIB after PCI and should consider performing timely endoscopy in patients who have undergone PCI and are suspected of having an UGIB.

    Full Text Available OBJECTIVE: To assess biochemical, anthropometric, and dietary variables considered risk factors for coronary artery disease. METHODS: Using anthropometrics, dietary allowance, and blood biochemistry, we assessed 84 patients [54 males (mean age of 55± 8 years and 30 females (mean age of 57±7 years], who had severe ( > or = 70% coronary artery obstruction and nonsevere forms of coronary artery disease determined by cardiac catheterization. The severe form of the disease prevailed in 70% of the males and 64% of the females, and a high frequency of familial antecedents (92% ' 88% and history of acute myocardial infarction (80% ' 70% were observed. Smoking predominated among males (65% and diabetes mellitus among females (43%. RESULTS: Males and females had body mass index and body fat above the normal values. Females with nonsevere lesions had HDL > 35 mg/dL, and this constituted a discriminating intergroup indicator. Regardless of the severity of the disease, hyperglycemia and hypertriglyceridemia were found among females, and cholesterolemia > 200 mg/dL in both sexes, but only males had LDL fraction > 160 mg/dL and homocysteine > 11.7 mmol/L. The male dietary allowance was inadequate in nutrients for homocysteine metabolism and in nutrients with an antioxidant action, such as the vitamins B6, C, and folate. Individuals of both sexes had a higher lipid and cholesterol intake and an inadequate consumption of fiber. The diet was classified as high-protein, high-fat, and low-carbohydrate. CONCLUSION: The alterations found had no association with the severity of lesions, indicating the need for more effective nutritional intervention.

    To investigate the levels of cardiovascular disease risk factors and their relations to clinical phenotype associated with coronary artery disease (CAD).Methods The subjects were recruited from five independent cardiovascular centers. Coronary angiography was employed to define the CAD with stenosis in each major vessel ≥70% and control with stenosis < 10% in every lesion.The classic risk factors including family history, body mass index, smoking habits, hypertension, diabetes mellitus, and serum lipid levels were surveyed according to established criteria. Associations between risk levels and clinical phenotypes were assessed by case control and correlation analysis.Results A total of 762 individuals were collected, including 481 men and 281 women, aged from 17 to 81 (mean 60 ± 10) years. The patients with CAD accounted for 55.5% of all participants, and controls 44. 5%, respectively. Compared with the pattern in published data, our study showed that mean serum high density lipoprotein cholesterol (HDL-C)level was significantly lower (P <0. 001 ) and triglycerides was significantly higher (P <0. 001 ), while total cholesterol (TC) and low density lipoprotein cholesterol levels were comparative ( both P > 0. 05 ). The prevalence of low HDL-C ( <40 g/L) and hypertriglyceridemia ( > 150 g/L) were 27. 2% and 41.4%, respectively. Mean serum levels of HDL-C and apolipoprotein A1 were significantly higher in female subjects than in male ( P < 0. 001 ). Lower HDL-C functioned as an independent risk factor for CAD only in men (RR = 2. 8, 95% CI: 1.5-4. 2, P < 0. 001 ), yet increased non-HDL cholesterol combined with diabetes mellitus and obesity seemed to play a key role in the development of CAD in women. Similarity in risk association with CAD was found for hypertension and TC/HDL ratio in male and female subjects, while family history had no relationship with the presence of CAD.Conclusion It is remarkable that emphasis of intervention in future

    In a cross-sectional study in Qazvin, Islamic Republic of Iran, 846 residents (425 men and 421 women) aged > or = 25 years were assessed for coronary heart disease and its associated risk factors comparing ischaemic and non-ischaemic groups. The age-adjusted prevalence of possible myocardial infarction, ischaemic ECG changes and angina pectoris were 4.2%, 36.8% and 2.2% respectively. There was no difference in the mean systolic and diastolic blood pressure and body mass index between ischaemic and non-ischaemic groups. There was a significant association between possible myocardial infarction and hypertension, type 2 diabetes, and smoking in women. There was also a significant association between ischaemic ECG changes and waist-hip ratio in women and between ischaemic ECG changes and hypertension in men.

    Full Text Available Objective: Morbidity and mortality rates due to acute renal failure (ARF developed in the postoperative period in patients undergoing coronary artery by-pass surgery (CABG, are increasing. After the determination of risk factors for the development of ARF in the perioperative period, treatment strategies to prevent the development of ARF can be implemented. Methods: Three hundred and nine patients who had undergone isolated CABG between May 2005 and December 2006 were included in the study. Patients’ data registered in the preoperative, intra-operative, and postoperative periods were collected in the electronic media. Factors possibly affecting the development of ARF in the postoperative period were determined by univariate analysis. Later, the independent risk factors affecting the development of ARF were determined by multivariate analysis.Results: Univariate analysis showed that there was a relation between old age, low ejection fraction (EF in the preoperative period, presence of COPD, high preoperative serum creatinine levels, long CPB duration, the requirement of intra-operative inotropic support, the amount of postoperative mediastinal drainage, peak creatinine levels, the amount of blood transfusions and postoperative ARF development.At the end of the evaluation of these factors with multivariate analysis; old age, high creatinine levels in the preoperative period, the requirement of inotropic support during the operation and increased amounts of postoperative mediastinal drainage were found to be independent risk factors for the development of ARF.Conclusions: ARF development is found to be higher in patients with old age, low EF, impaired preoperative renal functions. We suggest that implementing a close follow up with appropriate measures forthese patients can decrease the risk of ARF development postoperatively.

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

    Full Text Available OBJECTIVE: We examined whether a panel of SNPs, systematically selected from genome-wide association studies (GWAS, could improve risk prediction of coronary heart disease (CHD, over-and-above conventional risk factors. These SNPs have already demonstrated reproducible associations with CHD; here we examined their use in long-term risk prediction. STUDY DESIGN AND SETTING: SNPs identified from meta-analyses of GWAS of CHD were tested in 840 men and women aged 55-75 from the Edinburgh Artery Study, a prospective, population-based study with 15 years of follow-up. Cox proportional hazards models were used to evaluate the addition of SNPs to conventional risk factors in prediction of CHD risk. CHD was classified as myocardial infarction (MI, coronary intervention (angioplasty, or coronary artery bypass surgery, angina and/or unspecified ischaemic heart disease as a cause of death; additional analyses were limited to MI or coronary intervention. Model performance was assessed by changes in discrimination and net reclassification improvement (NRI. RESULTS: There were significant improvements with addition of 27 SNPs to conventional risk factors for prediction of CHD (NRI of 54%, P<0.001; C-index 0.671 to 0.740, P = 0.001, as well as MI or coronary intervention, (NRI of 44%, P<0.001; C-index 0.717 to 0.750, P = 0.256. ROC curves showed that addition of SNPs better improved discrimination when the sensitivity of conventional risk factors was low for prediction of MI or coronary intervention. CONCLUSION: There was significant improvement in risk prediction of CHD over 15 years when SNPs identified from GWAS were added to conventional risk factors. This effect may be particularly useful for identifying individuals with a low prognostic index who are in fact at increased risk of disease than indicated by conventional risk factors alone.

    We assessed the association of mitral annular calcification (MAC) with atherosclerotic risk factors and severity and complexity of coronary artery disease (CAD). Cardiac catheterization reports and electronic medical records from 2010 to 2011 were retrospectively reviewed. A total of 481 patients were divided into 2 groups: MAC present (209) and MAC absent (272). All major cardiovascular risk factors, comorbidities, and coronary lesion characteristics were included. On linear regression analysis, age (P = .001, β 1.12) and female gender (P = .031, β 0.50) were the independent predictors of MAC. Mitral annular calcification was not independently associated with the presence of lesions with >70% stenosis (P = .283), number of obstructive vessels (P = .469), lesions with 50% to 70% stenosis (P = .458), and Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery score (P = .479). Mitral annular calcification is probably a benign marker of age-related degenerative changes in the heart independent of the severity and complexity of CAD.

    Full Text Available Postoperative renal dysfunction is a relatively common and one of the serious complications of cardiac surgery. Though off-pump coronary artery bypass surgery technique avoids cardiopulmonary bypass circuit induced adverse effects on renal function, multiple other factors cause postoperative renal dysfunction in these groups of patients. Acute kidney injury is generally defined as an abrupt and sustained decrease in kidney function. There is no consen-sus on the amount of dysfunction that defines acute kidney injury, with more than 30 definitions in use in the literature today. Although serum creatinine is widely used as a marker for changes in glomerular filtration rate, the criteria used to define renal dysfunction and acute renal failure is highly variable. The variety of definitions used in clinical studies may be partly responsible for the large variations in the reported incidence. Indeed, the lack of a uniform definition for acute kidney injury is believed to be a major impediment to research in the field. To establish a uniform definition for acute kidney injury, the Acute Dialysis Quality Initiative formulated the Risk, Injury, Failure, Loss, and End-stage Kidney (RIFLE classification. RIFLE , defines three grades of increasing severity of acute kidney injury -risk (class R, injury (class I and failure (class F - and two outcome classes (loss and end-stage kidney disease. Various perioperative risk factors for postoperative renal dysfunction and failure have been identified. Among the important preoperative factors are advanced age, reduced left ventricular function, emergency surgery, preoperative use of intraaortic balloon pump, elevated preoperative serum glucose and creatinine. Most important intraoperative risk factor is the intraoperative haemodynamic instability and all the causes of postoperative low output syndrome com-prise the postoperative risk factors. The most important preventive strategies are the identification of the

    Objective To assess the prevalence of and related risk factors for aspirin resistance in elderly patients with coronary artery disease (CAD). Methods Two hundred and forty-six elderly patients (75.9 ± 7.4 years) with CAD who received daily aspirin therapy (≥ 75 mg) over one month were recruited. The effect of aspirin was assessed using light transmission aggregometry (LTA) and thrombelastography platelet mapping assay (TEG). Aspirin resistance was defined as ≥ 20% arachidonic acid (AA)-induced aggregation and ≥ 70% adenosine diphosphate (ADP)-induced aggregation in the LTA assay. An aspirin semi-responder was defined as meeting one (but not both) of the criteria described above. Based on the results of TEG, aspirin resistance was defined as ≥ 50% aggregation induced by AA. Results As determined by LTA, 23 (9.3%) of the elderly CAD patients were resistant to aspirin therapy; 91 (37.0%) were semi-responders. As determined by TEG, 61 patients (24.8%) were aspirin resistant. Of the 61 patients who were aspirin resistant by TEG, 19 were aspirin resistant according to LTA results. Twenty-four of 91 semi-responders by LTA were aspirin resistant by TEG. Multivariate logistic risk factor for aspirin resistance as determined by TEG. Conclusions A significant number of elderly patients with CAD are resistant to aspirin therapy. Fasting blood glucose level is closely associated with aspirin resistance in elderly CAD patients.

    Full Text Available With the increasing life span of man, the number of ageing people is also increasing, and along with that the number of diseases affecting them is also increasing. Atherosclerotic coronary artery disease is one of them. Coronary revascularization was started in 1960s through the pioneering efforts of David Sabiston and Kolessov. This is a retrospective descriptive study. A total number of 1050 Patients were operated on beating heart surgery from 1998 to Nov. 2002 out of which 852 patients were analysed to know the results and prognostic outcomes. Mean age was 57.8 years (range 31 - 80years with M:F ratio of 7:1. The pre-operative parameters studied were DM, HTN, hyperlipidemia, family history of CAD, smoking and past history of MI. other parameters included pulmonary disease, chronic renal failure, CVA, APD, PVD etc. 55.75% patients were diabetic, 53.99% were hypertensive and 24.4% had history of hyperlipidemia. Family history was positive in 12.9% of the patients, 25% were smokers and 44% had history of previous MI. average number of diseased vessels was 2.34 with triple vessel disease being most common. 6.6% had history of pulmonary diseases, 7.4% had pre-operative renal failure and 2% had past history of CV stroke. Overall in-hospital mortality was 1.4%. relative risk for mortality, morbidity, new onset of renal failure, CVA, arrhythmias, CCF were calculated. Mean hospital stay was 9.83days (range 6 - 41years, mean ICU stay was 74.3 hours (range 73 - 700years. Usage of blood and blood products was significantly less. Freedom from complications was 93%. LVEF<40%, age >70 years, high diastolic PA pressure> 15mm Hg were found to be significant risk factors for mortality. Females were found to be 2.6 times more at risk for mortality and development of complications as compared to males. Patients with previous history of MI were found to be more at risk of developing complications increasing their hospital and ICU stay.

    The OLR1 gene encodes the oxidized low-density lipoprotein receptor (LOX-1), which is responsible for the cellular uptake of oxidized LDL (Ox-LDL), foam cell formation in atheroma plaques and atherosclerotic plaque rupture. Alternative splicing (AS) of OLR1 exon 5 generates two protein isoforms with antagonistic functions in Ox-LDL uptake. Previous work identified six single nucleotide polymorphisms (SNPs) in linkage disequilibrium that influence the inclusion levels of OLR1 exon 5 and correlate with the risk of cardiovascular disease. Here we use minigenes to recapitulate the effects of two allelic series (Low- and High-Risk) on OLR1 AS and identify one SNP in intron 4 (rs3736234) as the main contributor to the differences in exon 5 inclusion, while the other SNPs in the allelic series attenuate the drastic effects of this key SNP. Bioinformatic, proteomic, mutational and functional high-throughput analyses allowed us to define regulatory sequence motifs and identify SR protein family members (SRSF1, SRSF2) and HMGA1 as factors involved in the regulation of OLR1 AS. Our results suggest that antagonism between SRSF1 and SRSF2/HMGA1, and differential recognition of their regulatory motifs depending on the identity of the rs3736234 polymorphism, influence OLR1 exon 5 inclusion and the efficiency of Ox-LDL uptake, with potential implications for atherosclerosis and coronary disease.

    Full Text Available Abstract Background Sphingomyelin (SM is the major phospholipid in cell membranes and in lipoproteins. In human plasma, SM is mainly found in atherogenic lipoproteins; thus, high levels of SM may promote atherogenesis. Methods We investigated in a median follow up of 6.0 years the association of SM with the incidence of a combined endpoint (myocardial infarction and cardiovascular death in stable and unstable patients, and its relation to other marker of atherosclerosis in 1,102 patients with angiographically documented CAD and 444 healthy controls. Results and discussion Logistic regression analysis showed that SM categorized by median was associated with an elevated risk for CAD (HR 3.2, 95%CI 2.5–4.0, p Conclusion The results of our study reveal that 1 human plasma SM levels are a risk factor for CAD; 2 the pro-atherogenic property of plasma SM might be related to metabolism of apoB-containing or triglyceride-rich lipoproteins; and 3 plasma SM levels are a predictor for outcome of patients with acute coronary syndrome.

    Full Text Available Background: coronary artery diseases (CAD are the leading cause of mortality, morbidity and disability with high health care cost in any countries including Iran. The prevalence of all CAD risk factors including hypertension, diabetes, lipid profile abnormalities and obesity is rising in the population of Iran. Knowing the population at risk would lead to proper education to decrease these risk factors and ultimately would reduce CAD.Methods: This descriptive cross- sectional study was conducted in February to December 2009 and comprised a total of 3115 Shiraz educational staff, aged 21- 73 years.Questionnaires were applied to collect information including; demographic data, physical activity, history of CAD, hypertension, dyslipidemia, and smoking. In addition, waist circumference, height, weight, body mass index (BMI, and hip circumference (HC were measured and serum biochemistry profiles were determined on venous blood samples. Such data helped identify the prevalence of diabetes, hypercholesterolemia, hypertriglyceridemia, hypertension, overweight and obesity, central obesity, and smoking. Results: The mean age of 3115 participant was 42.7 and 41.5 years for men and women respectively. The prevalence of pre-diabetes, diabetes hypertension, hypercholesterolemia and hypertriglyceridemia were %10.2, %4, %18.2, %38.30 and %33.2 respectively. Diabetes, hypertension and dyslipidemia were more prevalent among males and older subjects. The prevalence of central obesity was %75.05 (IDF criteria and %40.64 (ATP- III criteria. The frequency of obesity, current smoking, ex-smoking and passive smoking were %12.1, %5.85 , %1.52 ,%7.9 respectively which were below the reported prevalence in Iran in previous studies, but physical inactivity was %73.3 which is very high in this study group.Conclusion: Although CAD risk factors seem to be very common in the study population, clinical and paraclinical data indicated that teachers residing in Shiraz have a

    It is widely accepted that progression of organic stenosis in the coronary arteries and onset of acute coronary syndrome (ACS) are similar in the development of atherosclerosis. However, the extent of the association of each risk factor with the respective pathological conditions has not been fully elucidated. We investigated the differences in risk factors between these conditions using a statistical procedure. The study population consisted of 1,029 patients with ischemic heart disease (IHD). We divided the study population into two groups (ACS and non-ACS) and by diseased vessels (organic stenosis). Covariance structure analysis was simultaneously performed in one equation model for determination and comparison of the risk factors for organic stenosis and ACS. The analysis revealed that age (standardized regression coefficient, β: 0.206, P stenosis. HDL level (β: 0100, P = 0.002) and MDA-LDL level (β: 0.335, P stenosis than ACS, while MDA-LDL was significantly more strongly associated with ACS than organic stenosis. The current statistical analysis revealed clear differences among the risk factors between the progression of organic stenosis and the onset of ACS. Among them, the MDA-LDL level should be considered to indicate a substantial risk of ACS.

    The prevalence of major risk factors associated to coronary artery disease has changed over time. Today, the frequency of dyslipidemia, hypertension and diabetes mellitus has increased, while smoking has decreased. The birth cohort effect for coronary artery disease in subjects as an approximation of the true prevalence over time has not been studied in Latin-America. To determine the trends in the prevalence of major risk factors for coronary artery disease by birth cohort effect in a high risk population. We estimate the prevalence of diabetes mellitus, smoking, hypertension and dyslipidemia from a prospective institutional registry (DREST registry) of patients who underwent percutaneous coronary intervention for acute coronary event. Birth cohort effect was defined as a statistical, epidemiological and sociological methodology to identify the influence of the environment in the lifetime from birth by each decade. Univariate and multivariate analyses were performed adjusted by gender. Out of 3,056 subjects who were enrolled, 72% were male, with a median age of 61 years (interquartile range=53-69). Hypertension prevalence was 62.3%, for diabetes mellitus it was 48.8%, for smoking it was 18.8% and for dyslipidemia it was 48.8%. We observed an increase in prevalence for diabetes mellitus and dyslipidemia in each cohort according to birth decade, while there was a reduction in prevalence for hypertension in the same decades. The prevalence of major cardiovascular risk factors has changed in time and the presence of time at birth effect is evident, possibly influenced by the environment's social conditions in each decade of life.

    Full Text Available Alberto Palazzuoli, Maddalena Gallotta, Giuseppe Guerrieri, Ilaria Quatrini, Beatrice Franci, et alDepartment of Internal Medicine and Metabolic Diseases, Unit of Aortic Surgery, University of Siena, ItalyBackground: Abdominal aortic aneurysm (AAA is considered a manifestation of atherosclerosis, however there are epidemiologic, biochemical, and structural differences between occlusive atherosclerosis and AAA. The pathogenesis of AAA involves several factors, first of all destruction of collagen and elastin in the aortic wall. Classical risk factors may influence the evolution and development of AAA, though no consistent association has been found. Aims of the study were to evaluate associations between risk factors and to establish the prevalence of carotid, peripheral vascular and coronary atherosclerosis in patients with AAA.Methods: We studied 98 patients with AAA (Group 1 awaiting surgery compared with high cardiovascular risk population having two or more risk factors (n = 82 Group 2. We evaluated traditional risk factors and we studied by eco-doppler and echocardiography the presence of carotid peripheral and coronaric atherosclerosis in two groups.Results: We found a higher incidence of AAA in males (p < 0.01. The prevalence of infrarenal AAA was significantly higher than suprarenal AAA (81 vs 17 p < 0.001. No differences in total cholesterol (199 ± 20 vs. 197 ± 25 mg/dl, low-density lipoprotein (142 ± 16 vs. 140 ± 18 mg/dl, triglycerides (138 ± 45 vs. 144 ± 56 mg/dl, glycemia (119 ± 15 vs. 122 ± 20 mg/dl, and fibrinogen (388 ± 154 vs. 362 ± 92 mg/dl were found between groups.

    OBJECTIVE--To investigate the current and likely future provision of screening services for risk factors for coronary heart disease in retail pharmacies in Sheffield. DESIGN--This was a questionnaire survey asking about screening tests currently offered, price charged per test, likely future provision of screening tests, the action respondents would take upon finding an abnormal test result, whether the pharmacy was owner-run, franchised, or part of a commercial chain, and inviting open comments from respondents. SETTING--All retail pharmacy premises on the Sheffield Family Health Services Authority list. RESULTS--Seventy seven responses were obtained to 102 questionnaires distributed. Only nine of these currently offered any screening test other than pregnancy testing, although 37 indicated that they might offer tests in the future. Thirty nine were not offering screening and had no plans to do so. Pharmacies offering or likely to offer screening tests were mainly owner-run. All pharmacists who replied to the question asking about their action upon finding abnormal result (33) reported that they would advise the patient to see a doctor. The most frequent comments made by pharmacists were about the commercial viability of screening in pharmacies and the lack of space available to ensure patient privacy and confidentiality during screening. CONCLUSIONS--Screening in retail pharmacies would probably be a commercial failure unless doctors were able to contract for screening services from pharmacies. Evidence from this study and others, however, leads us to question the desirability of this option. PMID:8189175

    Retrospective study analysis concerning the prevalence of risk factors for unfavorable outcomes after coronary operations in patients with peripheral arterial atherosclerosis is presented. Meta-analysis of individual risk factors was carried out. Frequency of complications after coronary shunting in patients with various concomitant diseases is evaluated. The multifactorial relative risk affecting hospital lethality is defined. The study includes 131 patients with generalized atherosclerosis, which have underwent myocardial revascularization at the first stage (the main group) and at the second stage have been operated on abdominal aorta and peripheral arteries. 1128 patients without peripheral arterial atherosclerosis have made the control group. They underwent only coronary shunting. All patients were treated from December of 1994 till June of 2006. Relying on the results of the study cumulative relative risk for unfavorable outcomes after revascularization is 1.8 times higher in patients from the main group than in patients from the control group, and the risk for primary complications is 2.03 times higher. Concomitant atherosclerotic arterial involvement among cardiosurgical patients is associated with high risk for stroke in postoperative period. In case of chronic renal failure risk factors are cumulated. In the main group lethality made 5% , which was higher as compared with the control group. Correlation of such risk factors as heart failure and renal failure (creatinine level more than 1.8 mg/dl) with lethality has been revealed among patients from the main group. Lethality risk raises in 5.30 times in the presence of heart failure in medical history, and raises in 13.15 times in case of initially elevated creatinine level. Age of patient didn't have any influence on lethality in early postoperative period.

    2016-01-01

    BACKGROUND AND AIMS: The influence of gender and age on risk factor prediction of coronary artery calcification (CAC) in symptomatic patients is unclear. METHODS: From the European Calcific Coronary Artery Disease (EURO-CCAD) cohort, we retrospectively investigated 6309 symptomatic patients, 62......% male, from Denmark, France, Germany, Italy, Spain and USA. All of them underwent risk factor assessment and CT scanning for CAC scoring. RESULTS: The prevalence of CAC among females was lower than among males in all age groups. Using multivariate logistic regression, age, dyslipidaemia, hypertension......, diabetes and smoking were independently predictive of CAC presence in both genders. In addition to a progressive increase in CAC with age, the most important predictors of CAC presence were dyslipidaemia and diabetes (β = 0.64 and 0.63, respectively) in males and diabetes (β = 1.08) followed by smoking (β...

    Full Text Available Background: Whether coronary artery ectasia (CAE is a unique clinical finding or results from other clinical entities is still unknown. We aimed to determine the CAE prevalence, investigate the relationship between CAE and patients’ demographic and clinical characteristics, and assess the prognosis at follow-up in a sample of Iranian population.Methods: Totally, 10057 patients who underwent coronary angiography were divided into three categories: normal coronary arteries without co-existing coronary artery disease; CAE without co-existing coronary artery narrowing < 50%; and coronary artery stenosis with > 50% luminal narrowing (CAS.Results: The prevalence of CAE was 1.5%. Compared to the normal individuals, the CAE patients were older, were more frequently male, and had higher rates of myocardial infarction (MI. The CAE patients had a lower frequency of diabetes and MI than the CAS group. The CAE patients were largely focused between 40 to 60 years of age. The right coronary and left anterior descending arteries were the most involved arteries, and ectasia was located more frequently in the proximal part of these arteries. Patients with ectasia in the three main vessels had higher rates of MI. After a mean follow-up of 54.23 ±18.41 months, chest pain and dyspnea on exertion remained the main complaint in more than 97% of the patients, leading to hospital admission in more than 14%.Conclusion: There was no relationship between the presence of ectasia and conventional risk factors. According to our study, pure CAE may be deemed a benign feature of atherosclerosis; however, it can lead to frequent hospital admissions because of the persistence of cardiovascular symptoms.

    To determine the prevalence of aspirin resistance and associated risk factors based on biochemical parameters using whole blood multiple electrode aggregometry. The study was conducted at the outpatients cardiology clinic of the Universiti Kebangsaan Malaysia Medical Centre (UKMMC) from August 2011 to February 2012. Subjects on aspirin therapy were divided into two groups; first-ever coronary event and recurrent coronary event. Aspirin resistance was measured by a Multiplate(®) platelet analyser. A total of 74 patients (63 male, 11 female), with a mean age of 57.93 ± 74.1years were enrolled in the study. The patients were divided into two groups -first-ever coronary event group (n=52) and recurrent coronary event group (n=22). Aspirin resistance was observed in 12 out of 74 (16%) of the study patients, which consisted of 11 patients from the first-ever coronary event group and one patient from the recurrent coronary event group. There were significant correlations between aspirin resistance and age (r = -0.627; p = 0.029), total cholesterol (r = 0.608; p = 0.036) and LDL (r = 0.694; p = 0.012). LDL was the main predictor for area under the curve (AUC) for aspirin resistance. However, there was no association between aspirin resistance and cardiovascular events in both groups in this study. Aspirin resistance was observed in 16% of the study population. LDL was the major predictor of aspirin resistance. No association was found in the study between aspirin resistance with recurrent coronary events.

    To investigate whether there are sex differences in risk factor management of patients with established coronary heart disease (CHD), and to assess demographic variations of any potential sex differences. Patients with CHD were recruited from Europe, Asia, and the Middle East between 2012-2013. Adherence to guideline-recommended treatment and lifestyle targets was assessed and summarised as a Cardiovascular Health Index Score (CHIS). Age-adjusted regression models were used to estimate odds ratios for women versus men in risk factor management. 10 112 patients (29% women) were included. Compared with men, women were less likely to achieve targets for total cholesterol (OR 0.50, 95% CI 0.43 to 0.59), low-density lipoprotein cholesterol (OR 0.57, 95% CI 0.51 to 0.64), and glucose (OR 0.78, 95% CI 0.70 to 0.87), or to be physically active (OR 0.74, 95% CI 0.68 to 0.81) or non-obese (OR 0.82, 95% CI 0.74 to 0.90). In contrast, women had better control of blood pressure (OR 1.31, 95% CI 1.20 to 1.44) and were more likely to be a non-smoker (OR 1.93, 95% CI 1.67 to 2.22) than men. Overall, women were less likely than men to achieve all treatment targets (OR 0.75, 95% CI 0.60 to 0.93) or obtain an adequate CHIS (OR 0.81, 95% CI 0.73 to 0.91), but no significant differences were found for all lifestyle targets (OR 0.93, 95% CI 0.84 to 1.02). Sex disparities in reaching treatment targets were smaller in Europe than in Asia and the Middle East. Women in Asia were more likely than men to reach lifestyle targets, with opposing results in Europe and the Middle East. Risk factor management for the secondary prevention of CHD was generally worse in women than in men. The magnitude and direction of the sex differences varied by region. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017. All rights reserved.

    2014-12-01

    Full Text Available Background: Cardiovascular diseases are the main cause of 40% of deaths in Iran annually. Many patients undergoing coronary artery bypass graft surgery have previous cardiovascular risk factors which could be prevented. Objectives: The present study aimed to assess the prevalence of cardiovascular risk factors in the patients undergoing coronary artery bypass graft surgery. Materials and Methods: In this cross-sectional (descriptive – analytical study, a data collecting form was used. A total of 246 patients were selected from six hospitals of Shiraz using random stratification. Descriptive statistics were presented through figures and tables and t-test was used to analyze the continuous variables. All the statistical analyses were performed using the SPSS statistical software (version 15.0. Besides, P < 0.05 was considered as statistically significant. Results: Among the study patients, only 11.67% had no risk factors and 88.33% had one or more risk factors. The most common risk factors observed in the patients were hypertension, obesity and overweight, hyperlipidemia, and diabetes mellitus. The results showed a significant difference between males and females regarding the prevalence of hypertension (P = 0.001, diabetes (P = 0.028, hypercholesterolemia (P = 0.020, and cigarette smoking (P = 0.001. In addition, the patients' mean levels of cholesterol, LDL, triglyceride, and fasting blood sugar were higher than the acceptable level, while that of HDL was lower than the accepted level. Conclusions:: These patients are recommended to be trained regarding lifestyle changes. Also, prevention strategies can play an important role in reducing patient morbidity and mortality.

    Educational-related gradients in coronary heart disease (CHD) and mediation by behavioral risk factors are plausible given previous research; however this has not been comprehensively addressed in absolute measures. Questionnaire data on health behavior of 69,513 participants, 52 % women, from seven Danish cohort studies were linked to registry data on education and incidence of CHD. Mediation by smoking, low physical activity, and body mass index (BMI) on the association between education and CHD were estimated by applying newly proposed methods for mediation based on the additive hazards model, and compared with results from the Cox proportional hazards model. Short (vs. long) education was associated with 277 (95 % CI: 219, 336) additional cases of CHD per 100,000 person-years at risk among women, and 461 (95 % CI: 368, 555) additional cases among men. Of these additional cases 17 (95 % CI: 12, 22) for women and 37 (95 % CI: 28, 46) for men could be ascribed to the pathway through smoking. Further, 39 (95 % CI: 30, 49) cases for women and 94 (95 % CI: 79, 110) cases for men could be ascribed to the pathway through BMI. The effects of low physical activity were negligible. Using contemporary methods, the additive hazards model, for mediation we indicated the absolute numbers of CHD cases prevented when modifying smoking and BMI. This study confirms previous claims based on the Cox proportional hazards model that behavioral risk factors partially mediates the effect of education on CHD, and the results seems not to be particularly model dependent.

    Full Text Available Background: Prolonged mechanical ventilation is an important recognized complication occurring during cardiovascular surgery procedures. This study was done to assess the perioperative risk factors related to postoperative pulmonary complications and tracheostomy in women undergoing coronary artery bypass graft with cardiopulmonary bypass. Methods: It was a retrospective study on 5,497 patients, including 31 patients with prolonged ventilatory support and 5,466 patients without it; from the latter group, 350 patients with normal condition (extubated in 6-8 hours without any complication were selected randomly. Possible perioperative risk factors were compared between the two groups using a binary logistic regression model. Results: Among the 5,497 women undergoing coronary artery bypass graft (CABG, 31 women needed prolonged mechanical ventilation (PMV, and 15 underwent tracheostomy. After logistic regression, 7 factors were determined as being independent perioperative risk factors for PMV. Discussion: Age ≥70 years old, left ventricular ejection fraction (LVEF ≤30%, preexisting respiratory or renal disease, emergency or re-do operation and use of preoperative inotropic agents are the main risk factors determined in this study on women undergoing CABG.

    Controlling cardiovascular risk factors (CVRF) is important for the outcome of interventional practices (percutaneous coronary intervention [PCI]) in ischemic heart disease. The aim is to determine the evolution of the CVRF 6 months after the intervention and their relationship with new events. A descriptive study was conducted on a case series. The variables recorded were: age, sex and chronic kidney disease (CKD), as well as total (TC) and HDL cholesterol, systolic (SBP) and diastolic blood pressure (DBP), smoking habit, and body mass index (BMI), before PCI and after 6 months. The occurrence of death or new PCI during the follow-up was considered an independent variable in a logistic regression analysis. A P<.05 was assumed significant. A total of 222 cases (75.2% males) were included, with a mean age of 70.2 (SD 11.9) years, of whom 57.7% were hypertensive patients, 55.9% had hyperlipidemia, 50.4% were smokers or ex-smokers, and 28.2% were diabetics. After 6 months, 5% died, and 15.3% needed a new PCI, while 33% of the sample had all the CVRF considered. Decreases were observed in SBP (-3.3 mmHg), DBP (-2.6 mmHg), and TC (-35.2mg/dl). The emergence of new event was associated with age (OR: 1.06; P=.003) and CKD (OR: 3.7; P=.04). There is a high prevalence of CVRF. After 6 months, there was a decrease in blood pressure and TC, although incomplete control of CVRF was found. One fifth of the patients had an event in that period, showing association with age and CKD. Copyright © 2015 Elsevier España, S.L.U. All rights reserved.

    The purpose of the present work was to determine the plasma concentrations of fibrinogen and Von Willebrand Factor (VWF) as well as platelet aggregation, in an apparently healthy population of 306 men and 41 women, 33 to 65 years of age, workers of the national oil industry (PDVSA, Maracaibo), as a base investigation in a 5-year prospective national collaborative study. The participants were previously subjected to a thorough clinical examination with cardiovascular evaluation and laboratory tests. Clottable fibrinogen and VWF concentrations were determined in platelet poor plasma, the last one by immunoclectrophoresis, and a multimeric analysis of VWF was performed on those plasmas with concentrations higher than 150 U/dL by SDS agarose electrophoresis, followed by cellulose membrane transference. Platelet aggregation was studied in platelet rich plasma with no addition of stimulants and after collagen and ristocetin were added. Forty per cent of men and 65.8% of women, showed fibrinogen concentrations above 300 mg/dL (p < 0.01) and 12.2% of men and 15.4% of women had VWF values higher than 150 U/dL, with normal multimeric distribution. Fourteen individuals presented spontancous platelet aggregation and increased aggregation in 12 and 13 of them, after induction with collagen and ristocetin respectively. Comparing these findings with those of previous collaborative studies from other countries, the present results could mean that an important proportion of the population here studied, could be at risk for a future coronary event; however, as these are the base findings in Maracaibo, the significance of our results will be better evaluated at the end of the five year study.

    Vitamin D (25(OH)D) levels have been associated with cardiovascular disease. Thus, the aim of our study was to investigate the association of 25(OH)D levels with coronary heart disease (CHD) in 698 consecutive type 2 diabetic outpatients. 698 consecutive type 2 diabetic outpatients (25.2 % men, age 66 ± 9 years) and 100 (90 % men, age 65 ± 13 years) age-matched non-diabetic volunteers were enrolled. 25(OH)D assay and the main cardiovascular risk factors were explored. 25(OH)D concentration was 22 ± 10 ng/ml in control subjects and 18.23 ± 10 ng/ml in diabetic patients (p hypovitaminosis D was higher in diabetic patients than in control subjects (90 vs. 83 %, p hypovitaminosis D had higher prevalence of high values of A1C (p < 0.01), BMI (p < 0.01), LDL cholesterol (p < 0.01), triglycerides (p < 0.01), and glycemia (p < 0.01) than their vitamin D-sufficient counterparts. 25(OH)D and HDL cholesterol were lower (p < 0.01), while BMI (p < 0.01), age (p < 0.01), systolic (p < 0.01) and diastolic blood pressure (p < 0.01), diabetes duration (p < 0.01), A1C (p < 0.01), glycemia (p < 0.01), fibrinogen (p < 0.01), triglycerides (p < 0.01), and total (p < 0.01) and LDL cholesterol (p < 0.01) were higher in diabetic subjects with CHD than diabetic subjects without CHD. At the logistic regression analysis, the association of vitamin D with CHD was lost, while sex (p = 0.026), diabetes duration (p = 0.023), and age (p = 0.024) were the most powerful predictors of CHD. The current study demonstrates that 25(OH)D does not have a direct effect on CHD but may have an indirect effect mediated by cardiovascular risk factors such as diabetes duration, age, and sex.

    Full Text Available Objectives: Acute Coronary Syndrome (ACS is rare in women of reproductive age; however with increase in risk factors of Coronary Artery Disease (CAD in this age group, the possibility of ACS in young women is expected to rise and become a significant problem in future. It seems that pattern of risk factors and disease course may be different in this group. This study was conducted to determine the status of ACS in women of reproductive age. Materials and Methods: This is a descriptive study of women aged between 15-45 years who were admitted with ACS during the past five years from 21 March 2008 until 20 March 2013. The definition of ACS was designed to be compatible with current guidelines. Statistical analyses were performed with SPSS version 17.0. Results: Women of reproductive age who were admitted with ACS diagnosis were 1.16% of all ACS cases. Significant number of patients (22 patients who are 42% of all patients had atypical chest pain and 17 (32% had unusual symptoms. Unstable Angina (UA was the most common type of ACS. Most of the patients had one or more CAD risk factors. Percutaneous Coronary Intervention (PCI or Coronary Artery Bypass Graft Surgery (CABG was performed in 25(42% of the female patients with documented ACS. In recent years, the prevalence of CAD has increased considerably in in this specific group. Conclusion: ACS is rare in women of reproductive age but may occur. The clinical presentation of the women of this study is compatible to other similar investigations.

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

    Coronary heart disease (CHD) is the most common cause of mortality and morbidity world-wide. Evidence on ethnic differences between the Roma and non-Roma regarding medical risk factors is scarce. The aim of this study was to assess differences in medical risk factors and the severity of CHD in Roma compared with non-Roma CHD patients, adjusted for gender, age and education. Six hundred seventy four patients were included in this cross-sectional study (132 Roma, 542 non-Roma). Data on medical risk factors, symptoms, medication and severity of CHD were obtained from medical records. After matching Roma and non-Roma according to education, linear and logistic regression analyses with adjustments for gender and age were used. Compared with non-Roma, Roma patients had significantly more risk factors and more severe types of CHD. They were treated less frequently with statins and beta-blockers, were more frequently left on pharmacotherapy and surgically revascularised. These differences remained after controlling for education, gender and age. Roma CHD patients have a worse risk profile at entry of care and seem to be undertreated compared with non-Roma CHD patients.

    Aims Despite agreement on the need for screening for the presence of cardiovascular risk factors in first-degree family members of patients with premature coronary artery disease (CAD), this is not routinely carried out in relatives of normocholesterolaemic patients. We evaluated cardiovascular risk factors in family members of normocholesterolaemic patients with premature CAD. Methods Eligible index subjects were patients with premature CAD (6.5 mmol/l were excluded. Sixteen index subjects were included with a mean age of 49±8 years and total cholesterol levels of 5.5±0.8 mmol/l. Sixty-four first-degree relatives from these 16 pedigrees were screened, namely 18 children, 42 siblings and four parents. National Cholesterol Education Program III guidelines were used to identify candidates for lipid-lowering treatment. Furthermore, the presence of four additional metabolic disorders was investigated: the metabolic syndrome, increased levels of lipoprotein(a) (Lp(a)), hyperhomocysteinaemia and postprandial hyperlipidaemia. Results Of 64 relatives free of CAD, 34 subjects (53%) fulfilled the criteria to receive therapeutic advice, 20 of whom (31% of the relatives) were candidates for drug therapy. Sixty-one relatives were available for a full assessment of metabolic disorders and in 37 relatives (61%) at least one metabolic abnormality was present. Twelve subjects had hyper-Lp(a), seven subjects had postprandial hyperlipidaemia and two had the metabolic syndrome. Furthermore, 16 subjects had a combination of at least two out of four metabolic disorders. Conclusion Careful evaluation of coronary risk factors and metabolic variables in first-degree relatives of normocholesterolaemic CAD patients identifies a significant number of subjects at increased coronary risk in whom primary prevention measures should be initiated.

    Full Text Available The aim of this study was to investigate risk factors to coronary heart disease in two countryside villages in the State of Paraná, southern Brazil, typical in terms of the poverty and lack of access to public health care. All population was invited to participate in the study. The 462 volunteers (61.3% female, mean age = 42 years showed high prevalence of hypercholesterolemia (7.0%, hypertriglyceridemia (19.0%, hyperglycemia (11.0%, hypertension (30.0% and obesity (16.0%. The majority of the individuals, during the interview did not report the diseases detected by the testes. The results revealed that the high prevalence of hypercholesterolemia, hypertriglyceridemia, obesity, hypertension and diabetes mellitus could be consequence of the delayed detection of these diseases or inadequate treatment after diagnostic.O objetivo do presente estudo foi investigar os fatores de risco para doenças coronarianas em uma região pobre do Noroeste do Estado do Paraná - Brasil, onde o acesso a cuidados de saúde pública é deficiente.Toda a população foi convidada a participar do estudo, sendo que a população efetivamente estudada foi de 462 indivíduos, onde a maioria era mulheres (61,3% com idade média de 42 anos.

    An inverse association of adiponectin with coronary heart disease (CHD) has been reported, but the results are inconsistent. We used data from the CORA study to investigate into plasma concentrations of adiponectin and factors that may mediate the link to incident CHD. The CORA study is a population-based case-control study on 200 women with incident CHD and 255 age-matched controls. Plasma concentrations of adiponectin were significantly lower in women with CHD (por=25 kg/m(2) (por=0.85), prevalent diabetes or insulin resistance (HOMA-IR >or=3.8), or low HDL-cholesterol (<50mg/dl), and in smokers (each p<0.0001). Adiponectin also correlated with intake of fruit and vegetables, meat and sausage and alcohol as dietary markers of cardiovascular risk. Strikingly, the trend towards lower adiponectin concentrations with increasing BMI or waist circumference was less marked than the difference of adiponectin between CHD cases and controls. In a logistic regression model the odds ratio of adiponectin of 0.943 per 1 microg/ml (CI 0.919-0.968, p<0.0001) for risk of CHD was progressively reduced by elevated WHR, obesity-related risk factors, smoking, and dietary parameters. Plasma adiponectin indicates protection from CHD in women that is attenuated by combined effects of central obesity and dependent risk factors, parameters of nutrition and smoking. Thus, the impact of adiponectin goes beyond its relation to central adiposity, but may also reflect independent effects of lifestyle.

    Conclusions:: Advancing age may result in changes that could be atherogenic in the future. Such atherogenic changes have already initiated when the subjects are about 21 years old. The incidence of atherogenic changes is far greater when mothers who are having any of the risk factors such as obesity, diabetes, HTN and myocardial infarction than that fathers who are having similar risk factors.

    Obesity is associated with a host of cardiovascular risk factors and its prevalence is rising rapidly. Despite strong evidence that obesity predisposes to the development and progression of coronary heart disease (CHD), numerous studies have shown an inverse relationship between various measures of obesity (most commonly body mass index) and outcomes in established CHD. In this article we review the evidence surrounding the ≪obesity paradox≫ in the secondary care of CHD patients and the CHD presentations where a paradox has been found. Finally we discuss the impact of cardiorespiratory fitness and a number of mechanisms which may offer potential explanations for this puzzling phenomenon.

    While normal exercise myocardial perfusion imaging (SPECT-MPI) is a robust predictor of low short-term clinical risk, there is increasing interest in ascertaining how clinical factors influence long-term risk following SPECT-MPI. We evaluated the predictors of outcome from clinical data obtained at the time of testing in 12,232 patients with normal exercise SPECT-MPI studies. All-cause mortality (ACM) was assessed at a mean of 11.2 ± 4.5 years using the Social Security Death Index. The ACM rate was 0.8%/year, but varied markedly according to the presence of CAD risk factors. Hypertension, smoking, diabetes, exercise capacity, dyspnea, obesity, higher resting heart rate, an abnormal ECG, LVH, atrial fibrillation, and LVEF rates ranged from only 0.2%/year among patients exercising for >9 minutes having none of three significant risk factors (among hypertension, diabetes, and smoking) to 1.6%/year among patients exercising 9 minutes and had no significant risk factors (P term mortality risk varies markedly in accordance with baseline CAD risk factors and functional capacity among patients with normal exercise SPECT-MPI studies. Further study is indicated to determine whether the prospective characterization of both short-term and long-term risks following the performance of stress SPECT-MPI leads to improved clinical management.

  18. Membrane Omega-3 Fatty Acid Deficiency as a Preventable Risk Factor for Comorbid Coronary Heart Disease in Major Depressive Disorder

    Directory of Open Access Journals (Sweden)

    Robert K. McNamara

    2009-01-01

    Full Text Available Major depression disorder (MDD significantly increases the risk for coronary heart disease (CHD which is a leading cause of mortality in patients with MDD. Moreover, depression is frequently observed in a subset of patients following acute coronary syndrome (ACS and increases risk for mortality. Here evidence implicating omega-3 (n-3 fatty acid deficiency in the pathoaetiology of CHD and MDD is reviewed, and the hypothesis that n-3 fatty acid deficiency is a preventable risk factor for CHD comorbidity in MDD patients is evaluated. This hypothesis is supported by cross-national and cross-sectional epidemiological surveys finding an inverse correlation between n-3 fatty acid status and prevalence rates of both CHD and MDD, prospective studies finding that lower dietary or membrane EPA+DHA levels increase risk for both MDD and CHD, case-control studies finding that the n-3 fatty acid status of MDD patients places them at high risk for emergent CHD morbidity and mortality, meta-analyses of controlled n-3 fatty acid intervention studies finding significant advantage over placebo for reducing depression symptom severity in MDD patients, and for secondary prevention of cardiac events in CHD patients, findings that n-3 fatty acid status is inversely correlated with other documented CHD risk factors, and patients diagnosed with MDD after ACS exhibit significantly lower n-3 fatty acid status compared with nondepressed ACS patients. This body of evidence provides strong support for future studies to evaluate the effects of increasing dietary n-3 fatty acid status on CHD comorbidity and mortality in MDD patients.

    Under the available data gathered from a coronary study questionnaires with 10 792 cases, this article constructs a Bayesian network model based on the tabu search algorithm and calculates the conditional probability of each node, using the Maximum-likelihood. Pros and cons of the Bayesian network model are evaluated to compare against the logistic regression model in the analysis of coronary factors. Applicability of this network model in clinical study is also investigated. Results show that Bayesian network model can reveal the complex correlations among influencing factors on the coronary and the relationship with coronary heart diseases. Bayesian network model seems promising and more practical than the logistic regression model in analyzing the influencing factors of coronary heart disease.

    Full Text Available Abstract Background Sternal wound infection (SWI is an uncommon but potentially life-threatening complication of cardiac surgery. Predisposing factors for SWI are multiple with varied frequencies in different studies. The purpose of this study was to assess the incidence, risk factors, and mortality of SWI after coronary artery bypass grafting (CABG at Tehran Heart Center. Methods This study prospectively evaluated multiple risk factors for SWI in 9201 patients who underwent CABG at Tehran Heart Center between January 2002 and February 2006. Cases of SWI were confirmed based on the criteria of the Centers for Disease Control and Prevention. Deep SWI (bone and mediastinitis was categorized according to the Oakley classification. Results In the study period, 9201 CABGs were performed with a total SWI rate of 0.47 percent (44 cases and deep SWI of 0.22 percent (21 cases. Perioperative (in-hospital mortality was 9.1% for total SWI and about 14% for deep SWI versus 1.1% for non-SWI CABG patients. Female gender, preoperative hypertension, high functional class, diabetes mellitus, obesity, prolonged intubation time (more than 48 h, and re-exploration for bleeding were significant risk factors for developing SWI (p = 0.05 in univariate analysis. In multivariate analysis, hypertension (OR = 10.7, re-exploration (OR = 13.4, and female gender (OR = 2.7 were identified as significant predictors of SWI (p Conclusion Rarely reported previously, the two risk factors of hypertension and the female gender were significant risk factors in our study. Conversely, some other risk factors such as cigarette smoking and age mentioned as significant in other reports were not significant in our study. Further studies are needed for better documentation.

    Full Text Available Introduction. Death from coronary artery disease (CAD has been until recently considered rare in Nigeria. We present a report of a study of CAD with its predisposing cardiovascular (CVD risk factors in South South Nigeria. Methods. We examined the autopsy reports of 747 coroner cases and 41 consecutive clinically diagnosed cases of ischemic heart disease seen in South South Nigeria. Results. CAD was diagnosed in 13 (1.6% of 747 autopsies. They were predominantly males, urban residents, and of high social class with combination of CVD risk factors of hypertension, alcohol use, diabetes mellitus, cigarette smoking, poor physical activities, and obesity. The mean serum cholesterol of the clinical subjects was 4.7±1.57 mmol/L and 5.07±1.94 mmol/L for angina and myocardial infarction, respectively, which was higher than the mean total cholesterol for locality of 3.1 mmol/L. Conclusion. CAD and its risk factors are contributing to mortality and morbidity in South South Nigeria. These risk factors include hypertension, alcohol use, diabetes mellitus, cigarette smoking, poor physical activity, and obesity. Nigerians in this locality with CAD have raised serum lipids.

    Full Text Available This study was conducted to determine the prevalence of risk factors for coronary artery disease(CAD in apparently healthy middle aged and elderly population and to find the different betweenurban and rural group.Atotal of 160 individuals (80 urban and 80 rural were included in the study.All the subjects underwent detailed history and physical examination with special emphasis oncardiovascular system. The biochemical investigations were done in all the subjects which includedblood sugar, serum LDL and serum triglyceride levels. The prevalence of 2 or more than 2 riskfactors were observed in 95% subjects. The prevalence of smoking was 63%, which was moreprevalent in the rural population. The sedentary lifestyle was seen in 80% subjects more in femalesand urban group. The prevalence of asymptomatic hypertensives and isolated systolic hypertensionwere seen in 34% and 10% individuals respectively. Other risk factors were-diabetes mellitus (4%,Increase LDL (38%, hypertriglyceridemia (23% and central obesity (27.50%. The two mostcommon risk factors for CADwere sedentary lifestyle and smoking. These risk factors are modifiableand their reduction during adulthood can lead to marked reduction in the burden of CAD in middleaged and elderly Indian population.

    Full Text Available Aim. To compare the efficacy of correction of modifiable risk factors for ischemic heart disease (IHD, and treatment compliance within 6 months of observation in group of men and group of women after acute coronary syndrome (ACS. Material and мethods. Patients (n=147: 100 men and 47 women aged under 70 years who underwent ACS were examined. Prevalence of cardiovascular risk factors and frequency of basic drugs taking were evaluated at baseline and after 6 months. The efficacy of risk factors correction in men was compared with this in women. Results. A general number of patients with effective blood pressure (BP control as well as patients who reached the target levels of total cholesterol (TC <4.5 mmol/l and cholesterol of low>density lipoproteins (LDC <2.5 mmol/l after 6 months increased significantly in comparison with this before observation. Taking of drugs from all main groups left unsatisfactory and did not>reach the advisable values. Women have better antihypertensive treatment compliance, but worse lipidemia level control; they more often have glucose metabolism disorders, arterial hypertension and obesity. Men smoked more often, but have better BP, TC and cholesterol LDC control. Conclusion. The high prevalence of cardiovascular risk factors requires intensification of preventive activity regarding IHD onset and progression among both men and women.

    Objectives To evaluate the effect of different styles of coronary heart disease (CHD),different regions of acute myocardial infarction (AMI),its risk factors and branches of coronary stenosis on left ventricular remodeling and dysfunction by applying echocardiography. Methods 251 patients with CHD and 96 patients without CHD (NoCHD) were verified by selective coronary angiography. CHD patients were divided into stable angina pectoris(SAP) 26, unstable angina pectoris(UAP) 53, acute myocardial infarction (AMI) 140 and old myocardial infarction (OMI) 30 based on clinical situation, cTnT, cardiac enzyme and ECG. AMI patients were further divided into subgroups including acute anterior myocardial infarct (Aa,n =53), acute inferior myocardial infarction(Ai, n=54)and Aa+Ai(n=33) based on ECG. Cardiac parameters:end-diastolic interventricular septum thickness (IVSd),end-diastolic left ventricular internal diameter(LVd ),left ventricular mass (LM), end-diastolic left ventricular volume (EDV), end-systolic left ventricular volume (ESV) and left ventricular ejection fraction(LVEF) were measured by ACUSON 128XP/10 echocardiography.Multiples linear regression analyses were performed to test statistical associations between LVEF and the involved branches of coronary stenosis, blood pressure, lipids, glucose and etc after onset of myocardial infarction. Results EDV and ESV were increased and LVEF decreased on patients with AMI,OMI and UAP (P<0.05-0.0001). LM was mainly increased in patients with OMI (P<0.01) and LVd was mainly enlarged in patients with AMI. EF was significantly decreased and EDV, ESV, LM and LVd were remarkably increased in AMI patients with Aa and Aa+Ai. With the multiple linear regression analyses by SPSS software, we found that LVEF was negatively correlated to the involved branches of coronary stenosis as well as to systolic blood pressure after onset of myocardial infarction while there was no significant correlation between LVEF and other factors.

    Background We managed to assess and confirm the risk factors for mortality after coronary artery bypass grafting (CABG) operations so as to map out the proper guidance of surgical strategy especially in patients with low left ventricular ejection fraction (LVEF) in domestic polyclinic like ours.Methods Five hundred and forty-eight consecutive patients underwent CABG from December 1999 through August 2005 were analyzed retrospectively. Eighty-nine cases had an LVEF of 40% or less. All together twenty-two candidate factors were evaluated for their association with perioperative death using univariate and multivariate stepwise Logistic analysis.Results When data from all the patients who had undergone CABG were taken into account, LVEF, left ventricular end diastolic diameter (LVEDD), mitral regurgitation, aneurysm of the heart wall, mitral repair/replacement, resection of aneurysm, concomitant aortic valve replacement, and perioperative intra-aortic balloon counter-pulsation (IABP), left ventricular assist device (LVAD) and cardiopulmonary bypass (CPB) all showed an association with perioperative death in univariate analysis, while an LVEF of >40%, on the other hand, appeared to be a protective factor. In multivariate analysis, moderate to severe mitral regurgitation, aneurysm of the heart wall, repair of septal perforation and aortic regurgitation were proved to be risk factors. When the analysis was restricted to patients with an LVEF of 40% or less,such variables as age, LVEDD, mitral regurgitation, mitral repair/replacement, IABP, and CPB were qualified as risk factors in a univariate analysis. Age, moderate mitral regurgitation, aneurysm of the heart wall, CPB, left main coronary artery disease and female were associated with perioperative death in a multivariate logistic regression analysis.Conclusions Concerning the prognosis, patients who undergo CABG would have different risk factors when data from all the enrolled patients or data from patients with LVEF

    The main goal of our study was to evaluate possible perioperative risk factors for occurrence of atrial fibrillation in the postoperative period in patients after CABG operations. The study included 140 patients after CABG, divided into two groups - Group I - 64 patients with new onset of POAF and Group II - 76 patients without postoperative atrial fibrillation occurrence. In both groups possible risk factors for atrial fibrillation onset (preoperative and postoperative) were analyzed.Results showed that we can predict new onset of atrial fibrillation after CABG if the following preoperative factors are present - low ejection fraction (less than 40%), LAd > 40mm, higher body mass index (BMI over 30), presence of COPD and older age. Important perioperative factors for onset of atrial fibrillation in our study were longer extracorporeal circulation, increased dose/number of inotropic drugs, blood transfusion and elevated WBC count postoperatively.

    Objective To determine the prevalence of coronary risk factors in Paralympic athletes and evaluate their risk of coronary events. Method An observational prospective cross sectional study of 79 consecutive Brazilian Paralympic athletes (mean (SD) age 27.8 (6.7) years (median 26 years)). There were 56 men and 23 women, 67 with physical and 12 with visual disabilities. The occurrence of systemic hypertension, hypercholesterolaemia, diabetes mellitus, smoking, familial antecedents, obesity, and hypertriglyceridaemia was investigated. The risk of coronary events was calculated using the American Heart Association Coronary risk handbook, and also the 10 year probability of a coronary event using the Framingham risk score. Results The prevalence of risk factors was: systemic hypertension, 11%; familial antecedents, 10%; smoking, 9%; hypertriglyceridaemia, 6%; hypercholesterolaemia, 1.3%; obesity, 4%; diabetes, 0%. They occurred in 51% of the Paralympic athletes: one factor (41%), two factors (4%), and three factors (6%). The risk of coronary events was absent in 80%, slight in 17%, and moderate in 3%. This could only be evaluated in 81% of the athletes, as 8% had amputations, 9% were young, and 2% had unknown familial antecedents. The Framingham risk score ranged from −14 to +6, predicting a 10 year probability of a coronary event of 3.3 (3.8)%. Conclusion This study shows a reasonably high prevalence of coronary risk factors (51%), despite a low probability of coronary events in Paralympic athletes. The lipid and blood pressure profiles were similar in ambulatory and wheelchair athletes. PMID:16950883

    Coronary artery disease (CAD) is a complex trait caused by a number of genetic and environmental factors. Recently, paraoxonase/arylesterase (PONA) enzyme has been implicated in the pathogenesis of atherosclerosis. There is a 10-40-fold variability in the activity of this enzyme among individuals. This variability is due to the presence of an A/G polymorphism in the coding region of the gene (HUMPONA). The A and G alleles code for glutamine (A genotype) and arginine (B genotype), respectively. Individuals with A genotype have a lower enzymatic activity than those with B genotype. We determined the HUMPONA genotypes and alleles in 223 patients with angiographically documented CAD and in 247 individuals in the general population. The distribution of genotypes were in Hardy-Weinberg equilibrium in patients and in controls. Genotypes A and B were present in 120 (49%) and 28 (11%) individuals in controls and in 68 (30%) and 40 (18%) patients with CAD, respectively (chi squared= 16.5, P= 0.0003). The frequency of the A allele was 0.69 in controls and 0.56 in patients (OR= 1.7, P= 0.0001). There were no differences in the distribution of HUMPONA genotypes in the subgroups of patients with restenosis, myocardial infarction, or any of the conventional risk factors for CAD as compared with corresponding subgroups. In summary, variants of the HUMPONA gene are involved in predisposition to coronary atherosclerosis.

    Smoking, hypertension, and diabetes mellitus are the common risk factors among patients with coronary heart disease (CHD). High dietary fat intake, smoking, and lack of physical exercise have all been documented as independent risk factors for the development of CHD. The aim of the present study was to determine the prevalence of CHD risk factors among King Faisal University (KFU) male students in Dammam city, Saudi Arabia. A sample size of 10% of the target population (2054 male students of KFU colleges) was selected comprising 205 students. The study sample was selected by a multistage stratified random sampling technique with proportional allocation from all class levels. The response rate was 77.6%, where a total of 159 students were included in the study. Data was collected using an interviewer-administered questionnaire, which included sociodemographic variables and risk factors for CHD. The following measurements were performed: weight, height, body mass index (BMI), waist-to-hip ratio (WHR), blood pressure, and random capillary blood glucose. It was found that 28.9% of the university students do not practice any type of physical exercise. About 19% of the students were current smokers. A high proportion of university students were consuming fast foods, saturated fats, and soft drinks. Overweight (24.5%), obesity (11.9%), severe obesity (10.7%) as measured by BMI, as well as unacceptable WHR (10.7%) as an indicator of obesity were evident. Family history of obesity and unacceptable WHR were found to be statistically associated with increased obesity. Therefore, intervention programs to raise the health awareness of adolescents about CHD risk factors and encourage them to adopt a healthy dietary behavior, promote physical exercise and smoking cessation should be initiated.

    Full Text Available Abstract Background Several polymorphisms within the renin-angiotensin system cluster of genes have been associated with the advent of coronary artery disease (CAD or related pathologies. We investigated the distribution of 5 of these polymorphisms in order to find any association with CAD development and distinguish if any of the biochemical and behavioural factors interact with genetic polymorphisms in the advent of the disease. Methods ACE I/D (rs4340, ACE A11860G (rs4343, AT1R A1166C (rs5186, AGT T174M (rs4762 and AGT M235T (rs699 gene polymorphisms were PCR-RFLP analysed in 298 CAD patients and 510 controls from Portugal. Several biochemical and behavioural markers were obtained. Results ACE I/D DD and ACE11860 GG genotypes are risk factors for CAD in this population. The simultaneous presence of ACE I/D I and ACE11860 A alleles corresponds to a significant trend towards a decrease in CAD incidence. We found several synergistic effects between the studied polymorphisms and classical risk factors such as hypertension, obesity, diabetes and dyslipidaemia: the presence of the DD genotype of ACE I/D (and also ACE11860 GG increases the odds of developing CAD when associated to each one of these classical risk factors, particularly when considering the male and early onset CAD subgroup analysis; AGT235 TT also increases the CAD risk in the presence of hypertension and dyslipidaemia, and AT1R1166 interacts positively with hypertension, smoking and obesity. Conclusion ACE polymorphisms were shown to play a major role in individual susceptibility to develop CAD. There is also a clear interaction between RAS predisposing genes and some biochemical/environmental risk factors in CAD onset, demonstrating a significant enhancement of classical markers particularly by ACE I/D and ACE11860.

    Full Text Available Abstract Background The recent trends in sedentary life-styles and weight gain are likely to contribute to chronic conditions such as hypertension, diabetes, and cardiovascular diseases. The temporal sequence and pathways underlying these conditions can be modeled using the knowledge from the biomedical and social sciences. Methods The Framingham Offspring Study in the U.S. collected information on 5124 subjects at baseline, and 8, 12, 16, and 20 years after the baseline. Dynamic random effects models were estimated for the subjects' weight, LDL and HDL cholesterol, and blood pressure using 4 time observations. Logistic and probit models were estimated for the probability of diabetes and coronary heart disease (CHD events. Results The subjects' age, physical activity, alcohol consumption, and cigarettes smoked were important predictors of the risk factors. Moreover, weight and height were found to differentially affect the probabilities of diabetes and CHD events; body weight was positively associated with the risk of diabetes while taller individuals had lower risk of CHD events. Conclusion The results showed the importance of joint modeling of body weight, LDL and HDL cholesterol, and blood pressure that are risk factors for diabetes and CHD events. Lower body weight and LDL concentrations and higher HDL levels achieved via physical exercise are likely to reduce diabetes and CHD events.

    To analyse several cardiovascular risk factors by means of the physical activity performed by patients with acute coronary syndrome (ACS). Cross-sectional study. Cardiovascular prevention service (Health Department, Valencia, Spain). The study included 401 individuals with acute coronary syndrome and discharged from hospital 2-3months before the assessment. The inclusion criteria included age between 30 and 80years-old, no contraindication for physical activity, and no previous participation in cardiac rehabilitation programmes. Metabolic equivalent MET (Kcal/Kg) was calculated, based on the type of activity, frequency, duration and intensity. Participants were divided into two groups: sedentary group (cardiovascular risk factors were assessed: body mass index (BMI), waist circumference, lipid profile, blood glucose, and arterial pressure. The mean consumption was 8.24±12.5METs/week. Prevalent factors were overweight (77.05%), and dyslipidaemia (64.3%), whilst 64.8% were sedentary. The physically active group showed differences when compared to sedentary group in triglycerides (146.53±72.8 vs. 166.94±104.8mg/dL; 95%CI; P=.031), and BMI (27.65±3.86 vs. 28.50±4.38kg/m(2); 95%CI; P=.045). Physical activity was performed by a limited number of patients with ACS, with a prevalence of overweight and dyslipidaemia. Being physically active improved triglycerides levels and BMI. Therefore, health promotion from Primary Care and encouraging physical activity amongst patients with ACS is crucial. Copyright © 2017 Elsevier España, S.L.U. All rights reserved.

    Diabetes mellitus is a critical disease with higher rates of cardiovascular morbidity and mortality due to myocardial ischemia and infarction. There is growing interest in how to determine high-risk patients who are candidates for screening testing. This study was performed to evaluate the incidence of coronary artery disease (CAD) in diabetic patients detected by Tc-99m MIBI myocardial perfusion SPECT (MPS) and to assess risk factors of CAD and cardiac hard events. 203 diabetic patients (64 male, mean age 64.1 {+-} 9.0 years) who underwent MPS were included between Jan 2000 and July 2004. Cardiac death and nonfatal myocardial infarction (MI) were considered as hard events, and coronary angioplasty and bypass surgery >60 days after testing were considered as soft events. The mean follow-up period was 36 {+-} 18 months. Patients underwent exercise (n=6) or adenosine stress (n=197) myocardial perfusion SPECT. Perfusion defects on MPS were detected in 28.6% (58/203) of the patients. There was no cardiac death but 11 hard events were observed. The annual cardiac hard event rate was 1.1%. In univariate analysis of clinical factors, typical anginal pain, peripheral vascular disease, peripheral polyneuropathy, and resting ECG abnormality were significantly associated with the occurrence of hard events. Anginal pain, peripheral vascular disease, and resting ECG abnormality remained independent predictors of nonfatal MIs with multivariate analysis. Abnormal SPECT results were significantly associated with high prevalence of hard events but not independent predictors on uni- and multivariate analyses. patients who were male, had longer diabetes duration (especially over 20 years), peripheral vascular disease, peripheral polyneuropathy, or resting ECG abnormality had higher incidence of CAD. Among clinical factors in diabetic patients, typical angina, peripheral vascular disease, peripheral polyneuropathy, and resting ECG abnormality were strong predictors of hard events.

    Abdominal obesity is associated with metabolic risk factors for coronary heart disease (CHD). Although we previously found that using liposuction surgery to remove abdominal subcutaneous adipose tissue (SAT) did not result in metabolic benefits, it is possible that postoperative inflammation masked the beneficial effects. Therefore, this study provides a long-term evaluation of a cohort of subjects from our original study. Body composition and metabolic risk factors for CHD, including oral glucose tolerance, insulin resistance, plasma lipid profile, and blood pressure were evaluated in seven obese (39 +/- 2 kg/m(2)) women before and at 10, 27, and 84-208 weeks after large-volume liposuction. Liposuction surgery removed 9.4 +/- 1.8 kg of body fat (16 +/- 2% of total fat mass; 6.1 +/- 1.4 kg decrease in body weight), primarily from abdominal SAT; body composition and weight remained the same from 10 through 84-208 weeks. Metabolic endpoints (oral glucose tolerance, homeostasis model assessment of insulin resistance, blood pressure and plasma triglyceride (TG), high-density lipoprotein (HDL)-cholesterol, and low-density lipoprotein (LDL)-cholesterol concentrations) obtained at 10 through 208 weeks were not different from baseline and did not change over time. These data demonstrate that removal of a large amount of abdominal SAT by using liposuction does not improve CHD metabolic risk factors associated with abdominal obesity, despite a long-term reduction in body fat.

    Sari Voutilainen

    Full Text Available BACKGROUND: The role of circulating levels of total homocysteine tHcy in the development of coronary heart disease (CHD is still under debate. One reason for conflicting results between previous studies on homocysteine and heart diseases could be consequence of different interactions between homocysteine and genes in different study populations. Many genetic factors play a role in folate-homocysteine metabolism, like functional polymorphism (Val108Met in the Catechol-O-methyltransferase (COMT gene. METHODOLOGY AND FINDINGS: Our aim was to examine the role of COMT Val158Met polymorphism and interaction of this polymorphism with serum tHcy and folate concentration on the risk of acute coronary and events in middle-aged men from eastern Finland. A population-based prospective cohort of 792 men aged 46-64 years was examined as part of the Kuopio Ischaemic Heart Disease Risk Factor Study. During an average follow-up of 9.3 years, there were 69 acute coronary events in men with no previous history of CHD. When comparing the COMT low activity genotype with the others, we found an age and examination year adjusted hazard rate ratio (HRR of 1.73 (95% confidence interval (CI, 1.07-2.79, and an age, examination year, serum LDL and HDL cholesterol, and triglyceride concentration, systolic blood pressure and smoking adjusted HRR of 1.77 (95% CI, 1.05-2.77. Although serum tHcy concentration was not statistically significantly associated with acute coronary events (HRR for the highest third versus others 1.52, 95% CI, 0.93-2.49, subjects with both high serum tHcy and the COMT low activity genotype had an additionally increased adjusted risk of HRR 2.94 (95% CI 1.50-5.76 as compared with other men. CONCLUSIONS: This prospective cohort study suggests that the functional COMT Val158Met polymorphism is associated with increased risk of acute coronary events and it may interact with high serum tHcy levels.

    Conclusion: ACS and mechanical ventilation are important risk factors of UGIB at the early stage (≤ 2 weeks. Additionally, old age (>75 years, past peptic ulcer disease history, and the use of mechanical ventilation play important roles in the occurrence of UGIB at late stage (>2 weeks. However, it was also noted that use of PPI plays a protective role in patients with CAD receiving aspirin and clopidogrel therapy.

    To examine clinical characteristics, treatment and outcome of Kawasaki syndrome patients in Denmark. A retrospective chart review of hospitalization records for children Kawasaki syndrome discharge diagnosis identified through the Danish National Patient Registry during 1994 through June 2008 was conducted. A total of 284 cases Kawasaki syndrome (n = 279) and atypical Kawasaki syndrome (n = 5); 70.4% were Kawasaki syndrome patients were diagnosed with coronary artery abnormalities. Not receiving intravenous immunoglobulin treatment before the 10th day of illness, young age and male sex were significantly associated with the development of coronary artery abnormalities. In Denmark, more than one in 10 children with Kawasaki syndrome develop coronary artery abnormalities. Physicians should increase their index of suspicion for early diagnosis and treatment of Kawasaki syndrome among patients susceptible to increased risk of coronary artery abnormalities, particularly in infants who may have a more atypical presentation of the illness. ©2012 The Author(s)/Acta Paediatrica ©2013 Foundation Acta Paediatrica.

    Full Text Available Aims: We evaluated the synergistic effect of lipoprotein-associated phospholipase A2 (Lp-PLA2 in association with classical risk factors in predicting coronary heart disease (CHD and demonstrated the diagnostic value of Lp-PLA2 for predicting coronary stenotic lesions in subjects with CHD. Methods: Blood samples were acquired from 911 consecutive adult subjects (662 males and 249 females from 11 ethnic groups. Lp-PLA2 plasma levels were detected using a commercially available turbidimetric immunoassay (TIA. CHD in patients was confirmed using coronary angiography, and the severity of coronary atherosclerosis was assessed using the Gensini scoring system. Results: A binary logistic regression was performed to analyse the relationships between Lp-PLA2 and other risk factors. A multivariate logistic regression analysis revealed that Lp-PLA2 levels were significantly associated with CHD (OR, 1.882; 95% CI, 1.369-2.587, p=0.000.The area under the receiver operating characteristic curve for Lp-PLA2 was 0.589 (95%CI, 0.549-0.629, p=0.000.The synergism between Lp-PLA2 and other risk factors was also investigated. The proportion of CHD attributable to the interaction between Lp-PLA2 and age was as high as 64%. Conclusions: Lp-PLA2 levels in human plasma were positively associated with the severity of CHD, and there was a clear positive interaction between Lp-PLA2 and classical risk factors in predicting CHD.

    This study examined whether nurses could manage coronary risk factors in patients with unstable angina more effectively than physicians practicing usual care. Three hundred twenty-six patients were randomized in the emergency room to a 6-month program of risk factor management by a registered nurse versus participation in usual care. The nurse intervention consisted of a 30-minute counseling visit at 6 to 10 days after the chest pain episode and a second 30-minute session 1 month later. Multiple risk factors were assessed and addressed: smoking, blood lipids, blood pressure, blood glucose, physical inactivity, weight, psychological stress, and social isolation. Compared with usual care, nurse intervention patients significantly reduced both triglycerides (-29 +/- 8 vs 5 +/- 6 mg/dl; p chest pain is feasible and more effective than usual care in terms of fostering lifestyle changes that may lower coronary risk.

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

    Coronary artery disease (CAD) depends on multiple genetic and environmental factors. Adhesion molecules are markers of endothelium dysfunction. Intercellular adhesion molecule-1 (ICAM-1) interacts with leukocyte integrins and promotes atherosclerotic process at the surface of endothelial cells. The aim of the study was to assess the association between ICAM1 rs5498 polymorphism and CAD and to establish whether there are any interactions between this polymorphism and traditional risk factors in determining the risk of CAD. We studied 191 cases with angiographically documented CAD and 203 controls with no signs of cardiovascular diseases. The ICAM1 polymorphism was genotyped using PCR-RFLP method. Data were analyzed with the STATISTICA 7.1 and EpiInfo 6 softwares. We did not observe significant differences in the distribution of genotypes and alleles of rs5498 between cases and controls. We only found a tendency to a higher prevalence of G allele carriers (AG + GG) in patients compared to controls (68 vs. 64%, P = 0.399). A synergistic effect of G allele carrier-state and smoking that had influenced the risk of CAD [synergy index multiplicative (SIM = 2.09)] was observed. Smoking carriers of G allele compared to non-smoking AA were more prevalent in CAD group (39.8%) than among controls (13.3%, P < 0.0001, OR 4.81). Moreover, there was also a synergistic effect between G allele carrier-state and an elevated level of triacylglycerols (TG) (SIM = 1.28) increasing the risk of CAD. There is a synergistic interaction between rs5498 genotype and smoking that increases the risk of CAD.

    Full Text Available Abstract Background Previous studies suggested that genetic polymorphisms in the epidermal growth factor receptor (EGFR gene had been implicated in the susceptibility to some tumors and inflammatory diseases. EGFR has been recently implicated in vascular pathophysiological processes associated with excessive remodeling and atherosclerosis. Acute coronary syndrome (ACS is a clinical manifestation of preceding atherosclerosis. Our purpose was to investigate the association of the EGFR polymorphism with the risk of ACS. In this context, we analyzed the HER-1 R497K and EGFR intron 1 (CAn repeat polymorphisms in 191 patients with ACS and 210 age- and sex-matched controls in a Chinese population, using a polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP strategy and direct sequencing. Results There were significant differences in the genotype and allele distribution of R497K polymorphism of the EGFR gene between cases and controls. The Lys allele had a significantly increased risk of ACS compared with the Arg allele (adjusted OR = 1.49, 95% CI: 1.12–1.98, adjusted P = 0.006. However, no significant relationship between the number of (CAn repeats of EGFR intron 1 (both alleles P = 0.911. Considering these two polymorphisms together, there was no statistically significant difference between the two groups. Conclusion R497K polymorphism of the EGFR gene is significantly associated with the risk of ACS. Our data suggests that R497K polymorphism may be used as a genetic susceptibility marker of the ACS.

    The aim of this study was to provide an overview of the risk factors for acute myocardial infarction in patients attending Tripoli Medical Centre, Libya. Records were reviewed for 622 patients with a mean age of 58.3 (SD 12.9) years. Diabetes mellitus (48.2%), hypertension (35.7%) and smoking (50.6%) were among the risk factors reported. There were 110 patients (17.7%) who died during hospitalization, mainly suffering cardiogenic shock (48.0%). The rate of use of thrombolytic therapy was low in patients who were female (40.4% versus 58.4% for males), older age (31.6% for those > 85 years versus 63.3% for patients < 55 years), diabetics (45.3% versus 62.0% for non-diabetic patients) and hypertensives (47.3% versus 57.8% for non-hypertensive patients). Prevention strategies should be implemented in order to improve the long-term prognosis and decrease overall morbidity and mortality from coronary artery disease in Libyan patients.

    Full Text Available Backround/Aim. From 1984 to 2004 the city of Novi Sad participated through its Health Center “Novi Sad” in the international Multinational MONItoring of Trends and Determinants in CArdiovascular Disease (MONICA project, as one of the 38 research centers in 21 countries around the world. The aim of this study was to determine frequency and changes of trends in leading risk factors of coronary heart disease (CHD and to analyze the previous trend of movement of coronary event in women in Novi Sad during a 20- year period. Methods. In 2004, the fourth survey within MONICA project was conducted in the city of Novi Sad. The representative sample included 1,041 women between the age of 25 and 74. The prevalence of risk factors in CHD such as smoking, high blood pressure, elevated blood cholesterol, elevated blood glucose and obesity was determined. Also, indicators of risk factors and rates of coronary events in women were compared with the results from MONICA project obtained in previous three screens, as well as with the results from other research centres. χ2-test, linear trend and correlartion coefficient were used in statistical analysis of results obtained. Results. It was observed that during a 20-year period covered by the study, the prevalence of the leading risk factors for the development of CHD in the surveyed women was significantly increasing and in positive correlation with the values of linear trend. Also, the increase of morbidity rates and mortality rates of coronary event were in positive correlation. The decrease was only recorded in the period from 1985-1989 (the implementation of the intervention programme. Conclusion. Upon analysing the increase in prevalence of leading risk factors of CHD and significant increase in the rates of coronary event, we can conclude that health status of women in Novi Sad during a 20-year period was deteriorating.

    Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome occurring predominantly in young women without any cardiovascular risk factors, especially during the peripartum and early postpartum period. Here, we report a case of a 28-year-old pregnant woman who was found to have an isolated distal SCAD of the left anterior descending artery (LAD). Coronary angiography was complicated by extensive LAD and circumflex arteries dissection, requiring an emergency coronary artery bypass grafting associated with ventricular assist device implantation and underlying the extreme fragility of coronary arteries in pregnant women.

    Full Text Available Context: Coronary artery diseases are mostly detected using angiographic methods demonstrating arteries status. Nevertheless, Myocardial Infarction (MI may occur in the presence of angiographically normal coronary arteries. Therefore, this study aimed to investigate the prevalence of MI with normal angiography and its possible etiologies in a systematic review. Evidence Acquisition: In this meta-analysis, the required data were collected from PubMed, Science Direct, Google Scholar, Scopus, Magiran, Scientific Information Database, and Medlib databases using the following keywords: “coronary angiograph”, “normal coronary arteries”, “near-normal coronary arteries”, “heart diseases”, “coronary artery disease”, “coronary disease”, “cardiac troponin I”, “Myocardial infarction”, “risk factor”, “prevalence”, “outcome”, and their Persian equivalents. Then, Comprehensive Meta-Analysis software, version 2 using randomized model was employed to determine the prevalence of each complication and perform the meta-analysis. P values less than 0.05 were considered to be statistically significant. Results: Totally, 20 studies including 139957 patients were entered into the analysis. The patients’ mean age was 47.62 ± 6.63 years and 64.4% of the patients were male. The prevalence of MI with normal or near-normal coronary arteries was 3.5% (CI = 95%, min = 2.2%, and max = 5.7%. Additionally, smoking and family history of cardiovascular diseases were the most important risk factors. The results showed no significant difference between MIs with normal angiography and 1- or 2-vessel involvement regarding the frequency of major adverse cardiac events (5.4% vs. 7.3%, P = 0.32. However, a significant difference was found between the patients with normal angiography and those with 3-vessel involvement in this regard (5.4% vs. 20.2%, P < 0.001. Conclusions: Although angiographic studies are required to assess the underlying

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

    Full Text Available Abstract Background Process of accelerated atherosclerosis specific for uremia increases cardiovascular risk in patients with chronic kidney disease (CKD and may be influenced by the different structure of arteries. The study assesses the influence of traditional and novel risk factors on calcification of coronary arteries (CAC and abdominal aorta (AAC in hemodialysis patients (HD. Methods CAC and AAC were assessed by CT in 104 prevalent adult HD and 14 apparently healthy subjects with normal kidney function (control group. Mineral metabolism parameters, plasma levels of FGF-23, MGP, osteoprotegerin, osteopontin, fetuin-A, CRP, IL-6 and TNF-α were measured. Results CAC and AAC (calcification score ≥ 1 were found in 76 (73.1% and 83 (79.8% HD respectively, more frequent than in the control group. In 7 HD with AAC no CAC were detected. The frequency and severity of calcifications increased with age. Both CAC and AAC were more frequently detected in diabetics (OR = 17.37 and 13.00, respectively. CAC score was significantly greater in males. CAC and AAC scores were correlated significantly with pack-years of smoking and plasma osteoprotegrin levels. However the independent contribution of plasma osteoprotegerin levels was not confirmed in multiple regression analysis. Age (OR = 1.13 and hemodialysis vintage (OR = 1.14 were the independent risk factor favoring the occurrence of CAC; while age (OR = 1.20 was the only predictor of AAC occurrence in HD. Conclusions 1. AAC precedes the occurrence of CAC in HD patients. 2. The exposition to uremic milieu and systemic chronic microinflammation has more deteriorative effect on the CAC than the AAC.

    Ruiyue Yang

    Full Text Available BACKGROUND: Recent studies have determined that branched-chain (BCAAs and aromatic (AAAs amino acids are strongly correlated with obesity and atherogenic dyslipidemia and are strong predictors of diabetes. However, it is not clear if these amino acids are capable of identifying subjects with coronary artery disease (CAD, particularly with subclinical atherosclerosis who are at risk of developing CAD. METHODS: Four hundred and seventy two Chinese subjects (272 males and 200 females, 42-97 y of age undergoing physical exams were recruited at random for participation in the cross-sectional study. Serum BCAAs and AAAs were measured using our previously reported isotope dilution liquid chromatography tandem mass spectrometry method. Bilateral B-mode carotid artery images for carotid intima-media thickness (cIMT were acquired at end diastole and cIMT values more than 0.9 mm were categorized as increased. Correlations of BCAAs with cIMT and other CAD risk factors were analyzed. RESULTS: BCAAs and AAAs were significantly and positively associated with risk factors of CAD, e.g., cIMT, BMI, waist circumference, blood pressure, fasting blood glucose, TG, apoB, apoB/apoAI ratio, apoCII, apoCIII and hsCRP, and were significantly and negatively associated with HDL-C and apoAI. Stepwise multiple linear regression analysis revealed that age (β = 0.175, P<0.001, log BCAA (β = 0.147, P<0.001 and systolic blood pressure (β = 0.141, P = 0.012 were positively and independently associated with cIMT. In the logistic regression model, the most and only powerful laboratory factor correlated with increased cIMT was BCAA (the odds ratio of the fourth quartile compared to the first quartile was 2.679; P = 0.009. CONCLUSION: BCAAs are independently correlated with increased cIMT. This correlation would open a new field of research in the mechanistic understanding and risk assessment of CAD.

    The volatility of financial markets may cause substantial emotional and physical stress among investors. We hypothesize that this may have adverse effects on cardiovascular health. The Chinese stock markets were extremely volatile between 2006 and 2008. We, therefore, examined the relationship between daily change of the Shanghai Stock Exchange (SSE) Composite Index (referred as the Index) and coronary heart disease (CHD) deaths from 1 January 2006 to 31 December 2008 in Shanghai, the financial capital of China. Daily death and stock performance data were collected from the Shanghai Center for Disease Control and Prevention and SSE, respectively. Data were analysed with over-dispersed generalized linear Poisson models, controlling for long-term and seasonal trends of CHD mortality, day of the week, Index closing value, weather conditions, and air pollution levels. We observed a U-shaped relationship between the Index change and CHD deaths: both rising and falling of the Index were associated with more deaths and the fewest deaths coincided with little or no change of the index. We also examined the absolute daily change of the Index in relation to CHD deaths: in a 1-day lag model, each 100-point change of the Index corresponded to 5.17% (95% confidence interval: 1.71, 8.63%) increase in CHD deaths. Further analysis showed that the association was stronger for out-of-hospital CHD death than for in-hospital death. We found that CHD deaths fluctuated with daily stock changes in Shanghai, suggesting that stock volatility may adversely affect cardiovascular health.

    2014-06-01

    Full Text Available Background: Frailty may now be regarded as a geriatric syndrome of decreased reserve and resistance to stressors, resulting from cumulative declines across multiple physiologic systems, causing vulnerability to adverse health outcomes including falls, hospitalisation, institutionalisation and mortality. The inflammatory mediators as C-reactive protein have been associated with the development of the geriatric frailty. Several studies have pointed out increased level of homocystiene in frail elderly Increasing frailty was associated with lower bone mineral density, as both bone mass and muscle strength decrease during ageing and this has also been associated with higher risk of osteoporotic fractures in frail elderly. Objective: To compare frail and non-frail elderly regarding Bone mineral density, carotid circulation and serum levels of Homocysteine, coronary risk factors and CRP. Methods: 104 elderly patients, who were assigned to 2 groups. Group A (52 frail participants: diagnosed by Fried’s criteria as applied by Avila-Funes et al., 2008. Group B (52 non-frail participants.All participants were subjected to the following: through history, physical examination, ADL, IADL assessment, MMSE ,GDS, laboratory investigations including; CRP, homocystiene and total lipid profile, measurement of bone mineral density by DEXA and carotid intima-media thickness by carotid duplex. Results: There was no statistically significant difference in age, sex, among both groups.Frail participants had higher ADL and IADL dependence, higher incidence of depression, cognitive impairment and osteoprosis.They also had higher levels of homocystiene , CRP , CIMT and lower levels of HDL cholesterol. Conclusion: Osteoporosis is more prevalent among frail elderly also frailty is associated with more ADL & IADL dependence, higher GDS scores & lower MMSE score in addition to higher mean level of homocystiene, CRP & triglycerides in addition to low serum HDL & higher CIMT

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

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

    Background Persons infected with human immunodeficiency virus (HIV) have increased rates of coronary artery disease (CAD). The relative contribution of genetic background, HIV-related factors, antiretroviral medications, and traditional risk factors to CAD has not been fully evaluated in the setting of HIV infection. Methods In the general population, 23 common single-nucleotide polymorphisms (SNPs) were shown to be associated with CAD through genome-wide association analysis. Using the Metabochip, we genotyped 1875 HIV-positive, white individuals enrolled in 24 HIV observational studies, including 571 participants with a first CAD event during the 9-year study period and 1304 controls matched on sex and cohort. Results A genetic risk score built from 23 CAD-associated SNPs contributed significantly to CAD (P = 2.9×10−4). In the final multivariable model, participants with an unfavorable genetic background (top genetic score quartile) had a CAD odds ratio (OR) of 1.47 (95% confidence interval [CI], 1.05–2.04). This effect was similar to hypertension (OR = 1.36; 95% CI, 1.06–1.73), hypercholesterolemia (OR = 1.51; 95% CI, 1.16–1.96), diabetes (OR = 1.66; 95% CI, 1.10–2.49), ≥1 year lopinavir exposure (OR = 1.36; 95% CI, 1.06–1.73), and current abacavir treatment (OR = 1.56; 95% CI, 1.17–2.07). The effect of the genetic risk score was additive to the effect of nongenetic CAD risk factors, and did not change after adjustment for family history of CAD. Conclusions In the setting of HIV infection, the effect of an unfavorable genetic background was similar to traditional CAD risk factors and certain adverse antiretroviral exposures. Genetic testing may provide prognostic information complementary to family history of CAD. PMID:23532479

    Background The role of chronic hyperglycaemia as a coronary artery disease (CAD) risk factor is well-known,and the glycemic variability is still a matter of debate.The aim of this study was to investigate the association of admission glycemic excursion and hemoglobin A1c (HbA1c) with the presence and severity of CAD in patients with undiagnosed diabetes mellitus (DM).Methods We studied 286 newly diagnosed DM patients without prior revascularization undergoing coronary angiography for suspected ischaemic chest pain.Patients were grouped into those with CAD and without CAD according to angiographic results.The severity of CAD was assessed using the Gensini score.Glycemic variability,indicated as the mean amplitude of glycemic excursions (MAGE),was determined by a continuous glucose monitoring system.Serum levels of HbA1c and high-sensitive C-reactive protein (hs-CRP) as well as plasma concentrations of fasting glucose,lipids and creatinine were measured in all patients.Predictors of CAD were determined using multivariate Logistic regression model and receiver-operating characteristic (ROC) curves.Results The newly diagnosed DM patients with CAD were older,and more were male and current cigarette smokers compared with the patients without CAD.The CAD group had significantly higher levels of MAGE and HbA1c.Individuals with high levels of HbA1c (>7%) or MAGE (>3.4 mmol/L) had also significantly higher CAD prevalence.Logistic regression analysis revealed that high MAGE level and high HbA1c level were independent predictors for CAD.The area under the receiver-operating characteristic curve for MAGE (0.606,P=0.005) was superior to that for HbA1c (0.582,P=0.028).Gensini score closely correlated with age,MAGE,HbA1c,hs-CRP,creatinine and total cholesterol.Multivariate analysis indicated that age (P <0.001),MAGE (P <0.001),HbA1c (P=0.022) and hs-CRP (P=0.005) were independent determinants for Gensini score.Conclusions Both admission glycemic excursion and chronic

    It is still common practice to rely mostly on drug treatment for preventing cardiovascular disease, although a healthy nutrition has been defined that may prevent most premature cardiovascular events. This research raises the question of the magnitude of the effect of nutrition on cardiovascular disease independent of that of clinical risk factors, which are the targets of drug therapy. The study of coronary risk factors for atherosclerosis in women compares clinical, biochemical, and lifestyle factors in 200 consecutive pre- and postmenopausal women with incident coronary heart disease (CHD) to those in 255 age-matched population-based controls. Cases reported a higher intake of energy, predominantly through animal fat and protein reflected by a higher consumption of meat and sausage, while controls ate more fruit and vegetables. Multivariate analysis adjusted for clinical risk factors depicted a high intake of meat and sausage and a low consumption of fruit and vegetables as independent risk factors with an odds ratio of 2.5 (95% confidence interval 1.1-5.7) and 0.7 (95% confidence interval 0.5-1.0) for each 100 g per day, respectively. These dietary factors were found to be significantly more pronounced in cases with any clinical risk factor identified in this population as compared to controls with the same risk factors. The CORA-study clearly indicates a major impact of dietary habits on CHD in women independent of, and additive to, that of conventional risk factors. Thus, in clinical practice, the potential of nutrition as part of a healthy lifestyle is commonly greatly underestimated in favour of drug treatment.

    Full Text Available BACKGROUND: This study compares inflammation-related biomarkers with established cardiometabolic risk factors in the prediction of incident type 2 diabetes and incident coronary events in a prospective case-cohort study within the population-based MONICA/KORA Augsburg cohort. METHODS AND FINDINGS: Analyses for type 2 diabetes are based on 436 individuals with and 1410 individuals without incident diabetes. Analyses for coronary events are based on 314 individuals with and 1659 individuals without incident coronary events. Mean follow-up times were almost 11 years. Areas under the receiver-operating characteristic curve (AUC, changes in Akaike's information criterion (ΔAIC, integrated discrimination improvement (IDI and net reclassification index (NRI were calculated for different models. A basic model consisting of age, sex and survey predicted type 2 diabetes with an AUC of 0.690. Addition of 13 inflammation-related biomarkers (CRP, IL-6, IL-18, MIF, MCP-1/CCL2, IL-8/CXCL8, IP-10/CXCL10, adiponectin, leptin, RANTES/CCL5, TGF-β1, sE-selectin, sICAM-1; all measured in nonfasting serum increased the AUC to 0.801, whereas addition of cardiometabolic risk factors (BMI, systolic blood pressure, ratio total/HDL-cholesterol, smoking, alcohol, physical activity, parental diabetes increased the AUC to 0.803 (ΔAUC [95% CI] 0.111 [0.092-0.149] and 0.113 [0.093-0.149], respectively, compared to the basic model. The combination of all inflammation-related biomarkers and cardiometabolic risk factors yielded a further increase in AUC to 0.847 (ΔAUC [95% CI] 0.044 [0.028-0.066] compared to the cardiometabolic risk model. Corresponding AUCs for incident coronary events were 0.807, 0.825 (ΔAUC [95% CI] 0.018 [0.013-0.038] compared to the basic model, 0.845 (ΔAUC [95% CI] 0.038 [0.028-0.059] compared to the basic model and 0.851 (ΔAUC [95% CI] 0.006 [0.003-0.021] compared to the cardiometabolic risk model, respectively.

    It is not known the relationships between a difference in systolic blood pressure (SBP) or diastolic BP (DBP) between arms by synchronal measurement and the presence of coronary artery disease (CAD), and between a difference in BP between arms and the severity of coronary atherosclerosis. We enrolled 425 consecutive patients (M/F = 286/139, 67 ± 13 year) who were admitted to our University Hospital and in whom we could measure the absolute (|rt. BP - lt. BP|) and relative (rt. BP - lt. BP) differences in SBP and DBP using a nico PS-501(®) (Parama-Tech). We divided all patients into those who did and did not have CAD. The relative differences in SBP between arms in patients with CAD were significantly lower than those in patients without CAD. However, the relative difference in SBP between arms was not a predictor of the presence of CAD. We also divided 267 patients who underwent coronary angiography into tertiles according to the Gensini score (low, middle, and high score groups). Interestingly, the middle + high score groups showed significantly lower relative differences in SBP between arms than the low score group. The mean Korotkoff sound graph in the middle + high Gensini score group was significantly higher than that in the low Gensini score group. Among conventional cardiovascular risk factors and nico parameters, the relative difference in SBP between arms in addition to the risk factors (age, gender, body mass index, hypertension, dyslipidemia, and diabetes mellitus) was associated with the score by a logistic regression analysis. In conclusion, the relative difference in SBP between arms as well as conventional risk factors may be associated with the severity of coronary arteriosclerosis.

    Chronic kidney disease (CKD) and coronary artery disease (CAD) are strongly associated. CAD is the most frequent cause of cardiovascular death in patients with CKD. The prospective observational nationwide multicenter Coronary Artery Disease and REnal Failure (CAD-REF) Registry enrolled 3352 patients with angiographically documented CAD classified according to their baseline estimated glomerular filtration rate (eGFR) into 5 groups according to the K/DOQI-guidelines. Patients were followed for two years. The aim of this study was the analysis of outcome and the identification of risk factors for two-year mortality in patients with both CKD and CAD. With decreasing renal function, patients had more often diabetes mellitus, hypertension, peripheral artery disease, and previous cardiovascular events and interventions. The amount of diseased vessels increased with decreasing renal function. For the whole cohort, two-year mortality was 6.5%. Kaplan-Meier-curves showed highest mortality in patients with CKD stages 4 and 5 (22.4%). In multivariate Cox-regression analyses, significant risk factors for two-year all-cause mortality were lower eGFR, current smoking, left ventricular ejection fraction, diabetes mellitus treated with oral medication or insulin, age, and peripheral artery disease. Coronary status missed the level of statistical significance as a risk factor for mortality in multivariable regression analysis. An eGFR reduction of 10ml/min/1.73m(2) increased the risk of mortality by 19% regardless of other risk factors. Two-year morbidity and mortality increased with the degree of renal impairment. To improve survival of patients with CAD and CKD, nephroprotection is urgently needed especially for patients with atherosclerotic burden. NCT00679419, http://clinicaltrials.gov/.

    Background: Coronary sinus (CS) flow in response to a provocative stress has been used as a surrogate measure of coronary flow reserve, and velocity-encoded cine (VEC) magnetic resonance imaging (MRI) is an established technique for measuring CS flow. In this study, the cold pressor test (CPT) was used to measure CS flow response because it elicits an endothelium-dependent coronary vasodilation that may afford greater sensitivity for detecting early changes in coronary endothelial function. Purpose: To investigate the feasibility and reproducibility of CS flow reactivity (CSFR) to CPT using spiral VEC MRI at 3 Tesla in a sample of asymptomatic women with cardiovascular risk factors. Material and Methods: Fourteen asymptomatic women (age 38 years +- 10) with cardiovascular risk factors were studied using 3D spiral VEC MRI of the CS at 3 T. The CPT was utilized as a provocative stress to measure changes in CS flow. CSFR to CPT was calculated from the ratio of CS flow during peak stress to baseline CS flow. Results: CPT induced a significant hemodynamic response as measured by a 45% increase in rate-pressure product (P<0.01). A significant increase in CS volume flow was also observed (baseline, 116 +- 26 ml/min; peak stress, 152 +- 34 ml/min, P=0.01). CSFR to CPT was 1.31 +- 0.20. Test-retest variability of CS volume flow was 5% at baseline and 6% during peak stress. Conclusion: Spiral CS VEC MRI at 3 T is a feasible and reproducible technique for measuring CS flow in asymptomatic women at risk for cardiovascular disease. Significant changes in CSFR to CPT are detectable, without demanding pharmacologic stress

    Full Text Available Background/Aim. Ischemic heart disease is mostly a consequence of atherosclerosis. Besides the inflammation, the Fas/Fas ligand (FasL/caspase death pathway is documented to be activated in atherosclerotic lesions. The aim of this study was to compare the values of soluble forms of Fas and FasL in patients with different presentations of coronary disease and to correlate Fas/FasL with risk factors. Methods. We studied 30 patients with chronic stable angina pectoris (SAP, 27 with non-stable angina pectoris (NSAP, and 39 with acute ST-elevation myocardial infarction (STEMI and 27 age-matched healthy volunteers (the control group. Serum Fas/APO1 and FasL concentrations were determined using a commercially available enzymelinked immunoassays (ELISA. Results. Fas/APO-1 levels in the STEMI patients (6.981 ± 2.689 ng/mL were significantly higher than Fas levels in the controls (5.092 ± 1.252 ng/mL, p < 0.01, but not significantly higher than Fas values in the SAP (5.952 ± 2.069 ng/mL and the USAP patients (5.627±2.270 ng/ml. Levels of FasL did not show any significant difference among the studied groups. In the SAP patients Fas/APO1 showed a significant positive correlation with high sensitivity C-reactive protein (hsCRP (p < 0.05 and a negative correlation with high-density lipoprotein cholesterol (HDL-C (p < 0.05, while FasL showed a significant positive correlation with low-density lipoprotein cholesterol (LDL-C (p < 0.05. Fas levels between the patients having cholesterol within normal range and those whose cholesterol was above the normal range showed a significant difference (p < 0.05 only in the NSAP patients. Fas and FasL levels between the patients with hsCRP lower than 3.0 mg/L and those with hsCRP higher than 3.0 mg/L of the SAP group showed a significant differences (p < 0.001, p < 0.05, respectively. Strong correlation between Fas concentration and diabetes mellitus (p < 0.05 and FasL concentrations and both cholesterol (p < 0.01 and

    Thoracic aortic calcification (TAC) and coronary artery calcium (CAC) have been proposed for risk assessment of coronary artery and cardiovascular disease events. The aim of this analysis is to assess the prevalence of TAC and to determine its relationship with cardiovascular risk factors and CAC in a general unselected population. TAC was measured from electron beam computed tomography scans and quantified by Agatston-Score in 4,025 participants aged 45-75 years (mean age 59.4 ± 7.8 years, 53% female) from the Heinz Nixdorf Recall Study. Multivariable generalized linear regression was used to evaluate relationships between TAC and cardiovascular risk factors and CAC. Overall 2,538/4,025 (63.1%) participants revealed TAC. Prevalence of TAC was greater in men than in women (65.2 vs. 61.7%, p = 0.009). TAC was most strongly associated with age, systolic blood pressure, smoking and high levels of LDL-cholesterol. Prevalence of CAC was significantly higher in participants with TAC than without (74.0 vs. 57.6%, p CAC in the presence of TAC (prevalence ratio (PR) 1.29 [95% CI: 1.22-1.35], p TAC has high prevalence and largely shares cardiovascular risk factors with CAD while being independently associated with present CAC.

    Risk prediction algorithms for coronary heart disease (CHD) are recommended for clinical use. However, their predictive ability remains modest and the inclusion of genetic risk may improve their performance. QRISK2 was used to assess CHD risk using conventional risk factors (CRFs). The performance of a 19 single nucleotide polymorphism (SNP) gene score (GS) for CHD including variants identified by genome-wide association study and candidate gene studies (weighted using the results from the CARDIoGRAMplusC4D meta-analysis) was assessed using the second Northwick Park Heart Study (NPHSII) of 2775 healthy UK men (284 cases). To improve the GS, five SNPs with weak evidence of an association with CHD were removed and replaced with seven robustly associated SNPs - giving a 21-SNP GS. The weighted 19 SNP GS was associated with lipid traits (p<0.05) and CHD after adjustment for CRFs, (OR=1.31 per standard deviation, p=0.03). Addition of the 19 SNP GS to QRISK2 showed improved discrimination (area under the receiver operator characteristic curve 0.68 vs. 0.70 p=0.02), a positive net reclassification index (0.07, p=0.04) compared to QRISK2 alone and maintained good calibration (p=0.17). The 21-SNP GS was also associated with CHD after adjustment for CRFs (OR=1.39 per standard deviation, 1.42×10-3), but the combined QRISK2 plus GS score was poorly calibrated (p=0.03) and showed no improvement in discrimination (p=0.55) or reclassification (p=0.10) compared to QRISK2 alone. The 19-SNP GS is robustly associated with CHD and showed potential clinical utility in the UK population.

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

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

    We performed this study to compare of CAD risk factors in young male and female in Iran. In an analytic cross-sectional study, two groups of patients were evaluated with and without Coronary artery disease. The result of study suggests that there is a relationship between CAD and diabetes mellitus, increasing level of LDL and lipoprotein A in women, While CAD in men had more relation with smoking and opium use. High prevalence and uncontrolled diabetes mellitus in females and relatively high prevalence of opium consumption in males result in different premature CAD patterns.

    Full Text Available Abstract Background The ability of an intermittent fasting (IF-calorie restriction (CR regimen (with or without liquid meals to modulate adipokines in a way that is protective against coronary heart disease (CHD has yet to be tested. Objective Accordingly, we examined the effects of an IFCR diet on adipokine profile, body composition, and markers of CHD risk in obese women. Methods Subjects (n = 54 were randomized to either the IFCR-liquid (IFCR-L or IFCR-food based (IFCR-F diet for 10 weeks. Results Greater decreases in body weight and waist circumference were noted in the IFCR-L group (4 ± 1 kg; 6 ± 1 cm versus the IFCR-F group (3 ± 1 kg; 4 ± 1 cm. Similar reductions (P Conclusion These findings suggest that IFCR with a liquid diet favorably modulates visceral fat and adipokines in a way that may confer protection against CHD.

    Inflammation has been proposed as one of the factors responsible for the development of coronary artery disease (CAD) and high sensitivity C-reactive protein (hs CRP) at present is the strongest marker of inflammation. We did a study to assess the correlation of hs-CRP with socio-economic status (SES) in patients of CAD presenting as acute coronary syndrome (ACS). Baseline hs-CRP of 490 patients of ACS was estimated by turbidimetric immunoassay. Patients were stratified by levels of hs-CRP into low (3 mg/L) groups and in tertiles of 0-0.39 mg/L, 0.4-1.1 mg/L and >1.1 mg/L, respectively. Classification of patient into upper (21.4%), middle (45.37 percent) and lower (33.3%) SES was based on Kuppuswami Index which includes education, income and profession. Presence or absence of traditional risk factors for CAD diabetes, hypertension, dyslipidemia and smoking was recorded in each patient. Mean levels of hs-CRP in lower, middle and upper SES were 2.3 +/- 2.1 mg/L, 0.8 +/- 1.7 mg/L and 1.2 +/- 1.5 mg/L, respectively. hs-CRP levels were significantly higher in low SES compared with both upper SES (p = 0.033) and middle SES (p = 0.001). Prevalence of more than one traditional CAD risk factors was seen in 13.5%, 37.5% and 67.67 percent; in patient of lower, middle and upper SES. It was observed that multiple risk factors had a linear correlation with increasing SES. Of the four traditional risk factors of CAD, smoking was the only factor which was significantly higher in lower SES (73%) as compared to middle (51.67 percent;) and upper (39.4%) SES. We found that 62.3%, 20.8% and 26.5% patients of low, middle and upper SES had hs-CRP values in the highest tertile. Median value of the Framingham risk score in low, middle and upper SES as 11, 14 and 18, respectively. We observed that at each category of Framingham risk, low SES had higher hs-CRP. We conclude from our study that patient of lower SES have significantly higher levels of hs-CRP despite the fact that they have

    Current guidelines recommend the use of the Modified Diamond-Forrester (MDF) method to assess the pre-test likelihood of obstructive coronary artery disease (CAD). We aimed to compare the performance of the MDF method with two contemporary algorithms derived from multicenter trials that additionally incorporate cardiovascular risk factors: the calculator-based 'CAD Consortium 2' method, and the integer-based CONFIRM score. We assessed 1069 consecutive patients without known CAD undergoing coronary CT angiography (CCTA) for stable chest pain. Obstructive CAD was defined as the presence of coronary stenosis ≥50% on 64-slice dual-source CT. The three methods were assessed for calibration, discrimination, net reclassification, and changes in proposed downstream testing based upon calculated pre-test likelihoods. The observed prevalence of obstructive CAD was 13.8% (n=147). Overestimations of the likelihood of obstructive CAD were 140.1%, 9.8%, and 18.8%, respectively, for the MDF, CAD Consortium 2 and CONFIRM methods. The CAD Consortium 2 showed greater discriminative power than the MDF method, with a C-statistic of 0.73 vs. 0.70 (pMDF method. Adoption of these scores may improve disease prediction and change the diagnostic pathway in a significant proportion of patients. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    The objective of this study was to compare frequently used cardiovascular risk scores in predicting the presence of coronary artery disease (CAD) and 3-vessel disease. In 350 consecutive patients (218 men and 132 women) who underwent coronary angiography, the cardiovascular risk level was determined using the Framingham Risk Score (FRS), the Modified Framingham Risk Score (MFRS), the Prospective Cardiovascular Münster (PROCAM) score, and the Systematic Coronary Risk Evaluation (SCORE). The area under the curve for receiver operating characteristic curves showed that FRS had more predictive value than the other scores for CAD (area under curve, 0.76, P MFRS, PROCAM, and SCORE) may predict the presence and severity of coronary atherosclerosis.The FRS had better predictive value than the other scores.

    Objective Although risk factors of atrial fibrillation (AF) in the general population have been characterised, their impacts on patients with specific diseases are unclear. Our aim was to determine whether risk factors of AF are different in patients with and those without coronary artery disease (CAD). Methods We enrolled 1871 consecutive patients who underwent coronary angiography for evaluation of symptoms suggestive of CAD in the BOREAS-CAG Registry between August 2014 and January 2015. After exclusion of patients with valvular heart disease or a history of PCI/cardiac surgery, 1150 patients contributed to multivariate logistic regression analysis to identify risk factors of AF. We also retrieved data for 361 consecutive patients with CAD admitted to Sapporo Medical University Hospital between April 2013 and July 2014 and analysed data for 166 patients using the same inclusion and exclusion criteria as those in the BOREAS-CAG Registry. Results Unexpectedly, CAD was independently associated with the absence of AF. The patients were then divided into a non-CAD group (n=576) and a CAD group (n=574) for further analysis. The brain natriuretic peptide level showed a strong association with AF regardless of the presence or absence of CAD. In the non-CAD group, lack of statin use was independently associated with AF, whereas high serum uric acid level was an independent explanatory variable of AF in the CAD group. The association of AF with uric acid was confirmed in a separate group of patients (n=166) enrolled in the CAD cohort in Sapporo Medical University Hospital. Conclusions Major risk factors of AF are different in patients with CAD and those without CAD. Patients with CAD are more likely to develop AF when the serum uric acid level is high, whereas no statin administration predicts development of AF in patients without CAD. PMID:28123767

    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.

    An increased blood concentration of triglycerides (TG) has long been recognized as an important risk factor for cardiovascular disease. Through competition from HDL cholesterol and the arrival of statin treatment for high LDL cholesterol the importance of TG as risk factor was largely forgotten. A high concentration of TG indicates high blood levels of TG-rich lipoproteins including cholesterol rich remnant particles. Studies using Mendelian randomizations have demonstrated that a low HDL cholesterol does not carry a direct atherogenic function and that remnant particles do so. New efforts should be exercised in order to diminish residual cardiovascular risk during statin treatment through decreasing TG rich lipoproteins.

    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

    Patients with diabetes mellitus (DM) have increased mortality and morbidity of cardiovascular diseases compared with non-diabetic patients. The role of apolipoprotain E in lipid metabolism and cholesterol transport is well established. Apolipoprotein E gene (APO E) polymprphism that confers susceptibility to or protection from CAD in patients with type 2 DM may be quite different in different ethnic populations. We aimed to determine the frequencies of allelic variants of APO E in Egyptian population and to examine the relationship between APO E polymorphism and risk of coronary artery disease (CAD) in Egyptian type 2 diabetic patients. The study included 35 diabetic patients with CAD (group 1), 35 diabetic patients without CAD (group II) and 30 control subjects. All were subjected to history taking, clinical examination, and laboratory investigations for lipid profile and APO E genotyping by PCR-RFLP. Results revealed that epsilon3 allele was the commonest among the studied subjects (84%). The frequencies of epsilon2 and epsilon4 alleles were higher in group I (24.3% and 8.6% respectively) than group II and controls. The frequency of E2/E2, E2/E3, and E4/E3 genotypes was significantly higher in group I than group II and controls. Comparing group I vs. controls and group I vs. group II, multivariate analysis demonstrated significantly increased risk for CAD with epsilon4 and epsilon2 alleles vs. E3 (OR=7.02 and 4.97 respectively). In Conclusion, epsilon4 and E2 alleles are associated with higher risk of CAD in type2 DM than epsilon3 allele. Larger scale studies are still needed to either confirm or modify these results.

    Full Text Available AIMS: This study investigated the trends and levels of the prevalence of health factors, and the association of all-cause and cardiovascular (CVD mortality with healthy levels of combined risk factors among Lithuanian urban population. METHODS: Data from five general population surveys in Kaunas, Lithuania, conducted between 1983 and 2008 were used. Healthy factors measured at baseline include non-smoking, normal weight, normal arterial blood pressure, normal level of total serum cholesterol, normal physical activity and normal level of fasting glucose. Among 9,209 men and women aged 45-64 (7,648 were free from coronary heart disease (CHD and stroke at baseline, 1,219 death cases from any cause, 589 deaths from CVD, and 342 deaths from CHD occurred during follow up. Cox proportional hazards regression was used to estimate the association between health factors and mortality from all causes, CVD and CHD. RESULTS: Between 1983 and 2008, the proportion of subjects with 6 healthy levels of risk factors was higher in 2006-2008 than in 1983-1984 (0.6% vs. 0.2%; p = 0.09, although there was a significant increase in fasting glucose and a decline in intermediate physical activity. Men and women with normal or intermediate levels of risk factors had significantly lower all-cause, CVD and CHD mortality risk than persons with high levels of risk factors. Subjects with 5-6 healthy factors had hazard ratio (HR of CVD mortality 0.35 (95% confidence interval (CI 0.15-0.83 compared to average risk in the whole population. The hazard ratio for CVD mortality risk was significant in men (HR 0.34, 95% CI 0.12-0.97 but not in women (HR 0.38, 95% CI 0.09-1.67. CONCLUSIONS: An inverse association of most healthy levels of cardiovascular risk factors with risk of all-cause and CVD mortality was observed in this urban population-based cohort. A greater number of cardiovascular health factors were related with significantly lower risk of CVD mortality, particularly among

    Conclusions: Opium abuse was associated with depression and low PA. No ameliorative effect was observed on hypertension, diabetes, and plasma lipid profile. Therefore, positive association of opium with depression and LPA and the incorrectness of belief on its ameliorative effect on three other important risk factors of CAD should be clearly highlighted in public health messages to the community.

    To investigate the incidence, clinical characteristics and risk factors of upper gastrointestinal bleeding (UGIB) in patients with acute coronary syndrome (ACS) who were administrated with aspirin and clopidogrel dual antiplatelet therapy after percutaneous coronary intervention (PCI). ACS patients who had undergone PCI in the cardiovascular institute of Guangdong General Hospital from September 2009 to August 2014 were retrospectively enrolled.The incidence of UGIB and clinical characteristics of ACS patients on dual antiplatelet therapy for 1 year after PCI were analyzed.Risk factors of UGIB were screened in the cohort of patients and sex and age matched controls with ratio 1∶3. A total of 9 118 ACS patients had undergone PCI and UGIB occurred in 189 patients (2.07%, 189/9 118) from September 2009 to August 2014. UGIB patients with history over one year, gastrointestinal tumors or varices or negative endoscopy were excluded.Thus the revised incidence of UGIB occurred was 0.61% in 56 patients (0.61%, 56/9 118) and appeared to decline year by year.Most patients (91.07%, 51/56) had melena or stool occult blood positive (OB+ ), while others had bloody stool or haematemesis.Most UGIB were ulcer-related which was proved by endoscopy, accounting for 67.86% (38/56). There were 24 cases with duodenal ulcer, 13 with gastric ulcer and 1 with complex ulcer, while others were gastric erosion, gastritis and duodenitis.The risk factors of UGIB were previous history of peptic ulcer (Pfactor (P0.05). PPI use for the prevention of UGIB after PCI didn't increase the recurrence of ACS. The incidence of UGIB is 0.61% in ACS patients on dual antiplatelet therapy (aspirin and clopidogrel) for 1 year after PCI and falls year by year.Administration of PPI after PCI protects patients from UGIB, especially in those with precious history of peptic ulcer and renal impairment.

    Full Text Available BACKGROUND: Coronary heart disease (CHD mortality in the UK since the late 1970s has declined more markedly among higher socioeconomic groups. However, little is known about changes in coronary risk factors in different socioeconomic groups. This study examined whether changes in established coronary risk factors in Britain over 20 years between 1978-80 and 1998-2000 differed between socioeconomic groups. METHODS AND FINDINGS: A socioeconomically representative cohort of 7735 British men aged 40-59 years was followed-up from 1978-80 to 1998-2000; data on blood pressure (BP, cholesterol, body mass index (BMI and cigarette smoking were collected at both points in 4252 survivors. Social class was based on longest-held occupation in middle-age. Compared with men in non-manual occupations, men in manual occupations experienced a greater increase in BMI (mean difference = 0.33 kg/m(2; 95%CI 0.14-0.53; p for interaction = 0.001, a smaller decline in non-HDL cholesterol (difference in mean change = 0.18 mmol/l; 95%CI 0.11-0.25, p for interaction≤0.0001 and a smaller increase in HDL cholesterol (difference in mean change = 0.04 mmol/l; 95%CI 0.02-0.06, p for interaction≤0.0001. However, mean systolic BP declined more in manual than non-manual groups (difference in mean change = 3.6; 95%CI 2.1-5.1, p for interaction≤0.0001. The odds of being a current smoker in 1978-80 and 1998-2000 did not differ between non-manual and manual social classes (p for interaction = 0.51. CONCLUSION: Several key risk factors for CHD and type 2 diabetes showed less favourable changes in men in manual occupations. Continuing priority is needed to improve adverse cardiovascular risk profiles in socially disadvantaged groups in the UK.

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

    Objective To investigate the clinical risk factors and angiographic characteristics of young women with coronary heart disease, in order to provide the basis for clinical prevention, diagnosis and treatment. Methods One hundred and seventy-seven women under the age of 50 were selected from July 2012 to September 2014 with coronary heart disease or suspected coronary heart disease in the First Affiliated Hospital of Xinxiang Medical College. They were divided into coronary heart disease group (group A) and coronary artery normal group (group B) according to coronary angiography. According to the clinical features of coronary heart disease group was divided into stable angina, unstable angina and acute myocardial infarction. Comparative analysis was performed between the two groups to study the coronary heart disease risk factors and coronary angiographic features. Results (1) Traditional risk factors: compared to group B, there were more women with hypertension, menopause, diabetes, obesity (BMI≥28 kg/m2), reduced high-density lipoprotein, A-type personality in group A (P0.05). (2)New risk factors: compared with group B, serum levels of total bilirubin, indirect bilirubin were significantly decreased (P0.05). (3)Compared with the single branch lesion group, total bilirubin, indirect bilirubin were significantly decreased in the multi vessel disease group, the difference was statistically significant (P<0.05). The plasma fibrinogen level in the unstable angina and acute myocardial infarction group was significantly higher than that in stable angina pectoris, the difference was statistically significant (P<0.05). (4)Logistic regression analysis showed that the independent risk factors of coronary heart disease women under the age of 50 were hypertension (OR=6.302), reduced high-density lipoprotein (OR=3.490), A-type personality (OR=3.237) and high triglycerides (OR=2.338) (P<0.05).

    CD34-KDR- cell subpopulation within monocyte gate (514±173 mm(-3)) reached to highest counts in good collateral group among all study population. Endothelial progenitor cells can be mobilized from bone marrow to induce the coronary collateral growth in case of myocardial ischemia even in presence of the vascular risk factors and extensive atherosclerosis. This finding may be supportive to investigate the molecules, which can specifically mobilize EPC without inflammatory cells.

    The mechanism whereby the 9p21.3 locus confers risk for coronary artery disease remains incompletely understood. Risk alleles are associated with reduced expression of the cell cycle suppressor genes CDKN2A (p16 and p14) and CDKN2B (p15) and increased vascular smooth muscle cell proliferation. We asked whether risk alleles disrupt transcription factor binding to account for this effect. A bioinformatic screen was used to predict which of 59 single nucleotide polymorphisms at the 9p21.3 locus disrupt (or create) transcription factor binding sites. Electrophoretic mobility shift and luciferase reporter assays examined the binding and functionality of the predicted regulatory sequences. Primary human aortic smooth muscle cells (HAoSMCs) were genotyped for 9p21.3, and HAoSMCs homozygous for the risk allele showed reduced p15 and p16 levels and increased proliferation. rs10811656 and rs4977757 disrupted functional TEF-1 TEC1 AbaA domain (TEAD) transcription factor binding sites. TEAD3 and TEAD4 overexpression induced p16 in HAoSMCs homozygous for the nonrisk allele, but not for the risk allele. Transforming growth factor β, known to activate p16 and also to interact with TEAD factors, failed to induce p16 or to inhibit proliferation of HAoSMCs homozygous for the risk allele. Knockdown of TEAD3 blocked transforming growth factor β-induced p16 mRNA and protein expression, and dual knockdown of TEAD3 and TEAD4 markedly reduced p16 expression in heterozygous HAoSMCs. Here, we identify a novel mechanism whereby sequences at the 9p21.3 risk locus disrupt TEAD factor binding and TEAD3-dependent transforming growth factor β induction of p16 in HAoSMCs. This mechanism accounts, in part, for the 9p21.3 coronary artery disease risk. © 2015 American Heart Association, Inc.

    Full Text Available Introduction: The previous researches about the etiology of coronary artery atherosclerosis have accentuated on clinical and medical risk factors, such as cigarette smoking, hypertension, diabetes mellitus, hyperlipidemia, positive family background, myocardial ischemia history in family, atherogenic diet, increase of A lipoprotein, inflammatory factors such as increase of cross-reactive protein and so on. Although factors in behavioral medicine are recognized as an independent risk factor in coronary artery atherosclerosis, few researches have been done on hostility and anger. The aim of this study was to determine the difference between normal people(Control group and people with coronary artery atherosclerosis(Case group with regards to hostility and anger. Methods: This study was performed as a case-control design. Data was collected from seventy-seven patients with coronary artery atherosclerosis who had referred to Afshar Hospital Professional Heart Clinic in Yazd city and seventy-eight normal people were used as control. Two groups completed the Buss and Perry Aggression Questionnaire(BPAQ to measure their hostility and anger. Results: The results of the analysis showed that there was a statistically significant difference regarding hostility(p<.05 and anger(p<.001 between the two groups. Hierarchical multiple logistic regression analysis showed that the sociodemographic and clinical variables(step 1 explained 35.5 % to 47.4%, while hostility and anger(step 2 explained 6.7% to 9% of the variance in incidence of coronary artery atherosclerosis. Conclusion: Hostility and anger are strong risk factors for coronary artery atherosclerosis or CAD in Iran. Therefore, in order to decrease the incidence rate of coronary artery atherosclerosis in Iran, alongside medical interventions, attention should also be paid towards behavioral interventions in order to modify hostile and angrily behavior.

    We explored the relation between coronary artery calcium (CAC) and cardiac radiation doses in breast cancer survivors (BCS) treated with radiotherapy (RT). Additionally, we examined the impact of other risk factors and biomarkers of coronary artery disease (CAD). 236 BCS (median age 51years [range 30-70], median observation time 12years [9.2-15.7]), treated with 4-field RT of 50GY, were included and examined in 2004 (T1), 2007 (T2) and 2011 (T3) with clinical examination, blood tests and questionnaires. At T3, cardiac computed tomography was performed with quantification of CAC using Agatston score (AS). For 106 patients cardiac dose volume histograms were available. The cohort-based median of the mean cardiac dose was 2.5 (range 0.5-7.0) Gy. There was no correlation between measures of cardiac dose and AS. AS was correlated with high cholesterol at T1/T2 (p=0.022), high proBNP at T1/T2 (p<0.022) and T3 (p<0.022) and high HbA1c at T3 (p=0.022). In addition, a high AS was significantly associated with hypertension (p=0.022). Age (p<0.001) and cholesterol at T1/T2 (p=0.001) retained significant associations in multivariate analysis. Traditional, modifiable risk factors of CAD correlate with CAC and may be important for the long term risk of CAD after RT. With low to moderate cardiac radiation exposure, a contribution of radiation dose to CAC could not be demonstrated. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Low-dose aspirin (LDA) is the most commonly prescribed antiplatelet agent for prevention of cardiovascular events following percutaneous coronary intervention (PCI). Long-term treatment with LDA has serious adverse effects, including gastrointestinal (GI) hemorrhage. Most studies have focused only on upper GI bleeding and few studies have evaluated the effect of LDA on total GI bleeding. The aims of this study were to investigate the incidence and risk factors of total GI bleeding within 30 days after PCI in Japanese patients taking LDA. A retrospective chart review was conducted for 364 patients undergoing LDA therapy following PCI at Osaka City University Hospital. A retrospective case-control study evaluated risk factors using the chi-squared test and logistic regression. The incidence of total GI bleeding after PCI within 30 days was 4.3%. The source of the GI bleeding was located throughout the GI tract. Risk factors identified by univariate analysis were age ≥ 75 years, history of peptic ulcer disease, chronic renal failure, proton pump inhibitor use, and histamine H2 receptor antagonist use. By multivariate logistic regression only age ≥ 75 years (odds ratio = 5.26; 95% confidence interval: 1.13-24.51; p = 0.035) was found to be an independent risk factor of GI bleeding. The incidence of GI bleeding in patients undergoing LDA therapy following PCI is high. The bleeding episodes were located in the upper, middle, and lower GI tract. Age of ≥ 75 years was an independent risk factor for GI bleeding after PCI in patients on LDA therapy.

    OBJECTIVE: Examine the relation between IQ in early adulthood and later coronary heart disease (CHD) mortality, and assess the extent to which established risk factors measured in middle-age might explain this gradient. DESIGN: Cohort study of 4316 male former Vietnam-era US army personnel with IQ...... scores (mean age 20.4 years), risk factor data (mean age 38.3 years) and 15 years mortality surveillance. RESULTS: In age-adjusted analyses, lower IQ scores were associated with an increased rate of CHD mortality (hazard ratio per SD decrease in IQ; 95% confidence interval: 1.34; 1.00, 1.79). Adjustment...... for later chronic disease (1.22; 0.91, 1.64), behavioural (1.29; 0.95, 1.74) and physiological risk factors (1.19; 0.88, 1.62) led to some attenuation of this gradient. This attenuation was particularly pronounced on adding socioeconomic indices to the multivariable model when the IQ-CHD relation...

    Full Text Available Background: There are some conflicting results with Conventional Coronary Artery Bypass Grafts (CCABG with arrested heart in coronary high-risk patients. Moreover, performing off-pump CABG in these cases may be associated with serious complications. The objective of this study is to evaluate the efficacy of the on-pump beating CABG (OPBCABG in coronary high-risk patients in comparison with the conventional methods. Methods: In a prospective research study, 3000 off-pump CABG patients were considered during June 2003 to December 2011. Among these, 157 patients with one or more of the following risk factors were included for OPBCABG; severe left main stenosis, early post-acute myocardial infarction with ongoing chest pain, unstable angina, intractable ventricular arrhythmia, post complicated coronary intervention and severe left ventricular dysfunction. These patients were compared with 157 similar patients undergone CCABG with aortic cross clamp before 2003. Results: Preoperative patient characteristics revealed no significant differences between the two groups. The patients’ mean age and number of grafts were 57 years and 3 per patient respectively. Hospital mortality was 3.2% and 9% in OPBCABG and CCABG groups, respectively (P<0.001. Preoperative myocardial infarction, requirement of inotropic agents and intraaortic balloon pump, renal dysfunction and prolonged ventilation time were significantly higher in CCABG group. Conclusion: Our results suggest that OPBCABG is effective in coronary high-risk patients and significantly reduces mortality and the incidence of perioperative MI and other major complications.

    It is estimated that at least 80% of patients with cardiovascular disease (CVD) have conventional risk factors and optimization of these risk factors can reduce morbidity and mortality due to this disease considerably. Contemporary women have increased burden of some of these risk factors such as obesity, metabolic syndrome and smoking. Turkish women have a worse CV risk profile than Turkish men in some aspects. Risk stratification systems such as Framingham have a tendency of underestimating the risk in women. Coronary artery disease remains in vessel wall for a longer period of time in women; therefore obstructive disease appear later in their lifespan necessitating risk stratification systems for estimating their lifetime risk.

    Full Text Available Objective Indians have the highest risk rates for coronary artery disease (CAD among all ethnic groups. There is a paucity of data on the risk factors and clinical markers associated with premature CAD. We aimed to determine whether young CAD is due to preventable lifestyle-related factors and cutaneous clinical markers are useful in identifying at-risk patients. Design Single-centre retrospective study. Setting Tertiary care center. Participants A total of 292 patients (age ≤40 years who presented with acute CAD between January 2005 and June 2009 and 92 age, and gender-matched controls. Major outcome measures Details of smoking, family history of premature CAD, waist size, blood sugar and lipid profile. Clinical evidence of arcus juvenilis, premature greying of hair and premature baldness sought. Results Dyslipidaemia (91%, smoking (74.3%, low high-density lipoprotein cholesterol (HDL-C (68.9%, central obesity (47.7% and greying of hair (34.9% were the most commonly associated factors. Compared with male patients, females had greater prevalence of dyslipidaemia, low HDL-C, central obesity, hypertension, diabetes and family history of premature CAD. The presence of cutaneous markers was significantly associated with premature CAD. Conclusions CAD in young Indian people is multifactorial; dyslipidaemia, low HDL-C, smoking, hypertension, central obesity and family history of premature CAD are the most common risk factors. Smoking in men and central obesity in women are the most prevalent factors. Clinicians should be highly suspicious of patients with presence of cutaneous markers, and they should be followed intensively for lifestyle modifications.

    Background Associations of epicardial fat volume (EFV) measured on non-contrast cardiac computed tomography (NCT) include coronary plaque, myocardial ischemia and adverse cardiac events. Objectives This study aimed to define the relationship of EFV to coronary plaque type, severe coronary stenosis, and to the presence of high-risk plaque features (HRPFs). Methods We retrospectively evaluated 402 consecutive patients, with no prior history of coronary artery disease, who underwent same day non-contrast cardiac computed tomography (NCT) and coronary CT angiography (CTA). EFV was measured on NCT using validated, semi-automated, software. The coronary arteries were evaluated for coronary plaque type [calcified (CP), non-calcified (NCP) or partially-calcified (MP)] and coronary stenosis severity ≥70% using coronary CTA. For patients with NCP and PCP, 2 high risk plaque features were evaluated: Low-attenuation plaque and positive remodeling. Results There were 402 patients with a median age of 66 years (range 23–92) of whom 226 (56%) were male. The EFV was larger in patients with CP (112 ± 55 cm3 vs. 89 ± 39 cm3), PCP (110 ± 57 cm3 vs. 98 ± 45 cm3) and NCP (115 ± 44 cm3 vs. EFV 100 ± 52 cm3. In the 192 patients with PCP or NCP, on multivariable analysis, after adjusting for conventional cardiovascular risk factors, EFV was an independent predictor of ≥70% coronary artery stenosis (OR 3.0, 95% CI 1.3–6.6, p=0.008), any high risk plaque features (OR 1.7, 95% CI 0.9–3.4, p=0.04) and low attention plaque (OR 2.4, 95% CI 1.1–5.1, p=0.02), but not of positive remodeling. Conclusions Epicardial fat volume is larger in patients with CP, PCP and NCP. In patients with NCP and PCP, EFV is significantly associated with severe coronary stenosis, high risk plaque features and low attenuation plaque. PMID:23622507

    Reactive oxygen species (ROS) are involved in the pathogenesis of atherosclerosis and coronary artery disease (CAD). NADPH oxidases are the main source of ROS in the vasculature. p22phox is a critical component of vascular NADPH oxidases and is encoded by the CYBA (cytochrome b245 alpha) gene. The -930A>G CYBA polymorphism (rs9932581:A>G) modulates the activity of the CYBA promoter, and influences CYBA transcriptional activity. The aim of the present study was to analyze a possible association between the -930A>G polymorphism and CAD and to search for gene-traditional risk factors interactions. 480 subjects were studied: 240 patients with premature CAD, 240 age and sex matched blood donors. The -930A>G polymorphism was genotyped using the TaqMan® Pre-designed SNP Genotyping Assay (Applied Biosystems). The -930G allele carrier state was a risk factor for CAD (OR 2.03, 95% CI 1.21-3.44, P=0.007). A synergistic effect of the -930G allele with overweight/obesity (BMI≥25) and cigarette smoking was found. The estimated CAD risk for BMI≥25 and the -930G allele interaction was about 160% greater than that predicted by assuming additivity of the effects, and about 40% greater for interaction of cigarette smoking and the -930G allele. Overweight/obesity was a risk factor for CAD only in the -930G allele carriers (PG CYBA polymorphism is associated with CAD in the Polish population. The -930G allele carriers are particularly at risk of consequences of obesity and tobacco smoke exposure.

    The aim of this study was to examine the incidence, correlates, and consequences of intra-procedural stent thrombosis (IPST) in patients with acute coronary syndromes (ACS). Stent thrombosis (ST) is a rare but serious complication of percutaneous coronary intervention (PCI). The Academic Research Consortium definition of ST excludes events occurring during PCI. Angiograms from the ACUITY (Acute Catheterization and Urgent Intervention Triage StrategY) and HORIZONS-AMI (Harmonizing Outcomes with RevascularIZatiON and Stents in Acute Myocardial Infarction) trials were reviewed frame-by-frame at an independent core laboratory for the occurrence of IPST. Patients with versus without IPST were compared to identify baseline characteristics associated with IPST and demonstrate the independent association between IPST and adjudicated events at 30 days and 1 year. Intra-procedural ST occurred in 47 (0.7%) of 6,591 patients. The occurrence of IPST was associated with ST-segment elevation myocardial infarction presentation, high white blood cell count, treatment of thrombotic and bifurcation lesions, bivalirudin monotherapy, bail-out IIb/IIIa inhibitor use, and implantation of bare-metal (rather than drug-eluting) stents. Major adverse ischemic events were markedly higher in patients with versus without IPST, including mortality at 30 days (12.9% vs. 1.4%, p definite or probable ST also occurred significantly more often among IPST patients at 30 days (17.4% vs. 1.8%, p < 0.0001) and 1 year (19.9% vs. 2.7%, p < 0.0001). Intra-procedural ST was a significant independent predictor of 1-year mortality (hazard ratio: 3.86, 95% confidence interval: 1.66 to 9.00, p = 0.002). Intra-procedural ST is a relatively rare complication of PCI in ACS but is strongly associated with subsequent out-of-lab ST and mortality. Intra-procedural ST should be considered as a distinct category of ST and routinely reported, particularly for ACS patients. Copyright © 2013 American College of Cardiology

    Previous studies have suggested that a high intake of sugar-sweetened beverages is positively associated with the risk of a coronary event. However, a few studies have examined the association between sucrose (the most common extrinsic sugar in Sweden) and incident coronary events. The objective of the present study was to examine the associations between sucrose intake and coronary event risk and to determine whether these associations are specific to certain subgroups of the population (i.e. according to physical activity, obesity status, educational level, alcohol consumption, smoking habits, intake of fat and intake of fruits and vegetables). We performed a prospective analysis on 26 190 individuals (62 % women) free from diabetes and without a history of CVD from the Swedish population-based Malmö Diet and Cancer cohort. Over an average of 17 years of follow-up (457 131 person-years), 2493 incident cases of coronary events were identified. Sucrose intake was obtained from an interview-based diet history method, including 7-d records of prepared meals and cold beverages and a 168-item diet questionnaire covering other foods. Participants who consumed >15 % of their energy intake (E%) from sucrose showed a 37 (95 % CI 13, 66) % increased risk of a coronary event compared with the lowest sucrose consumers (event.

    of incident acute coronary heart disease and stroke. Results Compared with more educated smokers, the less educated had an added increase in absolute risk of cardiovascular disease of 3.1% (95% confidence interval + 0.1%, +6.2%) in men and of 1.5% (-1.9%, +5.0%) in women, consistent across smoking categories......Background The combined effect of social status and risk factors on the absolute risk of cardiovascular disease has been insufficiently investigated, but results provide guidance on who could benefit most through prevention.

    The paraoxonase (PON1) gene polymorphisms are known to affect the PON1 activity and coronary artery disease (CAD) risk. Studies done so far have given conflicting results. In the present study, we determined the role of PON1 genetic variants and PON1 activity in the development of CAD in North-West Indian Punjabis, a distinct ethnic group, having high incidence of both CAD and type 2 diabetes. 300 angiographically proven CAD with type 2 diabetics and 250 type 2 diabetics with no clinically evident CAD were enrolled. Serum PON1 activity and genotyping of coding (Q192R, L55M) and promoter (-909G/C, -162A/G, -108C/T) region polymorphisms were carried out and haplotypes were determined using PHASE software. The serum PON1 activity was significantly lower in CAD with type 2 diabetics as compared to diabetics alone (51.0 vs. 114.2nmol/min/ml). In logistic regression model after adjusting for confounding variables, lower PON1 activity was found to be significantly associated with CAD risk in type 2 diabetics with OR being 16.8 (95% CI: 10.2-27.7). The lower serum PON1 activity, irrespective of genotypes and haplotypes is a risk factor for development of CAD in North-West Indian Punjabis with type 2 diabetics.

    Full Text Available Hypertension and diabetes mellitus are considered to be two major atherosclerotic risk factors for coronary artery disease (CAD. A stress-induced protein identified to be dermcidin isoform 2 of Mr. 11 kDa from blood plasma of hypertensive persons when injected (0.1 μM in rabbits increased the systolic pressure by 77% and diastolic pressure by 45% over the controls within 2 h. Ingestion of acetyl salicylic acid (150 mg/70 kg by these subjects reduced systolic (130 mm Hg and diastolic pressures (80 mm Hg with reduction of plasma dermcidin level to normal ranges (9 nM. The protein was found to be a potent activator of platelet cyclooxygenase and inhibited insulin synthesis. Aspirin was found to reduce hypertension by reduction of plasma dermcidin level, neutralized the effect of cyclooxygenase, and restored the pancreatic insulin synthesis through NO synthesis. These results indicated that dermcidin could be a novel atherosclerotic risk factor for its hypertensive and diabetogenic effects.

    Full Text Available Coronary heart disease (CHD is the leading cause of mortality in African Americans. To identify common genetic polymorphisms associated with CHD and its risk factors (LDL- and HDL-cholesterol (LDL-C and HDL-C, hypertension, smoking, and type-2 diabetes in individuals of African ancestry, we performed a genome-wide association study (GWAS in 8,090 African Americans from five population-based cohorts. We replicated 17 loci previously associated with CHD or its risk factors in Caucasians. For five of these regions (CHD: CDKN2A/CDKN2B; HDL-C: FADS1-3, PLTP, LPL, and ABCA1, we could leverage the distinct linkage disequilibrium (LD patterns in African Americans to identify DNA polymorphisms more strongly associated with the phenotypes than the previously reported index SNPs found in Caucasian populations. We also developed a new approach for association testing in admixed populations that uses allelic and local ancestry variation. Using this method, we discovered several loci that would have been missed using the basic allelic and global ancestry information only. Our conclusions suggest that no major loci uniquely explain the high prevalence of CHD in African Americans. Our project has developed resources and methods that address both admixture- and SNP-association to maximize power for genetic discovery in even larger African-American consortia.

    Full Text Available Background: Atrial fibrillation (AF is the most common arrhythmic complication following coronary artery bypass surgery (CABG. The incidence of postoperative AF ranges from %10 to %0 and it usually tends to occur within 2 to 4 days after operation. The etiology of AF after cardiac surgery is incompletely understood. Aggressive prophylactic intervention should be directed and limited to high risk patients who are most likely to benefit from such procedure. The aim of this study was to identify the frequency of AF and to determine risk factors by using available clinical predictors of postoperative AF after CABG.Methods: The present study was a prospective observational investigation of 300 patients undergoing elective isolated CABG from 2006 to 2008 in Urumiyeh Imam Khomeini Hospital. Peri-operative risk factors were used to develop logistic regression equation in order to predict the development of post-operative AF. Results: A total of 300 patients aged 58± 10 (221 male were included in the study. The incidence of AF was %12/3(n=37. By univariate analysis, congestive heart failure (P=0.02, and low left ventricular ejection fraction (P=0.04 were associated with the development of post-CABG AF. However, in the logistic regression model CHF (OR: 4.87, 95%CI: 1.09-21.6, P=0.038 remained an independent predictor for the development of postoperative AF. On the other hand, patients with and without AF were similar regarding body mass index, preoperative heart rate , time of ventilation in ICU, pump time, grafting or absence of grafting on right coronary artery (RCA and the prevalence of chronic lung diseases, previous myocardial infarction, and diabetes mellitus. Patients who developed AF had longer ICU stay (OR=4.92, P=0/000.Conclusion: The results of the present study demonstrated that the combination of congestive heart failure, and low left ventricular ejection fraction can identify patients at high risk for occurrence of AF after CABG.

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

    Current medical technology permits the early detection of risk factors for coronary artery disease (CAD) in adults, and interventions are available to prevent CAD-related morbidity and mortality. The goal of this study was to determine the effectiveness of a Qigong exercise intervention in improving biomarker levels and mental and physical health outcomes in community-dwelling adults diagnosed with CAD risk factors, in a southern Taiwanese city. Participants were randomly assigned to an experimental (n= 84) group that participated in a 60-min Qigong group session 3 times per week for 3 months or a control (n= 61) group that did not receive the intervention. Self-perceived mental and physical health assessed with the Chinese Health Questionnaire-12, and body fat percentage were measured at baseline and 6, 12, and 16 weeks. Blood samples were collected at baseline and 12 weeks for analysis of lipid profiles, high-sensitivity C-reactive protein (hs-CRP), glycated hemoglobin (HbA1c), and fasting plasma sugar. Linear mixed model analyses revealed that experimental participants had significantly improved perceived mental and physical health and body fat percentage compared to the control group at 6 and 12 weeks but not 16 weeks. The lipid profiles were significantly more improved in the Qigong group than in the control group at 12 weeks. Qigong exercise, however, had no significant effects on hs-CRP, HbA1c, or fasting plasma sugar. Findings suggest that Qigong exercise improves a limited number of CAD risk factors in community-dwelling adults aged 40 years and over.

  17. Renal dysfunction and coronary disease: a high-risk combination.

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

    The incomplete inhibition of platelet function by acetylsalicylic acid (ASA), despite the patients are receiving therapeutic doses of the drug ('aspirin-resistance'), is caused by numbers of risk factors. In this study we verified the idea that plasma homocysteine (Hcy) contributes to 'aspirin-resistance' in patients with coronary artery disease (CAD) and with or without type 2 diabetes mellitus (T2DM). A cross-designed randomized controlled intervention study has been performed (126 CAD pts incl. 26 with T2DM) to determine whether increasing ASA dose from 75mg to 150mg daily may result in the increased antiplatelet effect, in the course of four-week treatment. Platelet response to collagen (coll) or arachidonic acid (AA) was monitored with whole blood aggregometry, plasma thromboxane (Tx), and Hcy levels were determined immunochemically. The ASA-mediated reductions in platelet response to coll (by 12±3%) or AA (by 10±3%) and in plasma Tx (by 20±9%; p<0.02 or less) were significantly greater for higher ASA dose and significantly correlated with plasma Hcy, which was significantly lower in "good" ASA responders compared to "poor" responders (p<0.001). Higher plasma Hcy appeared a significant risk factor for blood platelet refractoriness to low ASA dose (OR=1.11; ±95%CI: 1.02-1.20, p<0.02, adjusted to age, sex and CAD risk factors). Hcy diminished in vitro antiplatelet effect of low ASA concentration and augmented platelet aggregation (by up to 62% (p<0.005) for coll and up to 15% (p<0.005) for AA), whereas its acetyl derivative acted oppositely. Otherwise, Hcy intensified antiplatelet action of high ASA. Hyperhomocysteinaemia may be a novel risk factor for the suppressed blood platelet response to ASA, and homocysteine may act as a specific sensitizer of blood platelets to some agonists. While homocysteine per se acts as a proaggregatory agent to blood platelets, its acetylated form is able to reverse this effect. Thus, these findings reveal a possibly new

    Full Text Available Introduction: A central component of the atherosclerotic process is inflammation. Single nucleotide polymorphisms (SNPs present in the promoter region of various cytokines can lead to altered levels of the transcript and a state of low-grade inflammation exacerbating the risk of coronary artery disease (CAD. The present work tries to understand the role of permissive promoter variants in the interleukin-6 gene (IL-6-174G/C and the tumor necrosis factor alpha (TNFα-308G/A in the causation of CAD and also dyslipidemia. Materials and Methods: Genotyping was conducted on 100 cases of CAD and 150 controls by the allele termination assay SNaPshot. Biochemical parameters were determined by routine enzymatic endpoint methods. The results were analyzed by appropriate statistical methods. Results: No differences in the minor allele frequency IL-6-174G/C SNP were seen between cases and controls (0.13 vs. 0.12. The differences in the allele frequency of TNFα-308A between cases (6% and controls (2% have led to an odds ratio, 3.370; 95% confidence interval, 1.039-11.543; P=0.033 in the univariate analysis. In the final logistic regression analysis, however none of the variants were associated with an increased risk of CAD. Conclusions: In summary, no association of the permissive promoter variants in the IL-6 gene and the TNFα gene were seen with an increased CAD risk. These and other studies highlight the importance of doing population specific studies.

    Full Text Available Abstract Background Triglycerides is an independent risk factor for coronary artery disease (CAD and is especially important in Indians because of high prevalence of hypertriglyceridemia in this population. Both genetic and environmental factors determine triglyceride levels. In a birth cohort from India, hypertriglyceridemia was found in 41% of men and 11% of women. Subjects who had high triglycerides had more rapid body mass index (BMI or weight gain than rest of the cohort throughout infancy, childhood and adolescence. We analysed polymorphisms in APOA5, hepatic lipase and PPARγ genes and investigated their association with birth weight and serial changes in BMI. Results Polymorphisms in APOA5 (-1131T > C, S19W, PPARγ (Pro12Ala and hepatic lipase (-514C > T were studied by polymerase chain reaction (PCR followed by restriction digestion in 1492 subjects from the New Delhi Birth Cohort (NDBC. We assessed whether these polymorphisms influence lipid and other variables and serial changes in BMI, both individually and together. The risk allele of APOA5 (-1131C resulted in 23.6 mg/dl higher triglycerides as compared to normal allele (P PPARγ Pro12Ala variation with a lower conditional weight at 6 months, (P = 0.020 and APOA5 S19W with a higher conditional BMI at 11 yrs of age (P = 0.030, none of the other associations between the gene polymorphisms and serial changes in body mass index from birth to young adulthood were significant. Conclusion The promoter polymorphism in APOA5 was associated with raised serum triglycerides and that of HL with raised HDL2 levels. None of the polymorphisms had any significant relationship with birth weight or serial changes in anthropometry from birth to adulthood in this cohort.

    To compare the magnitude of multivariable coefficients and hazard ratios of four cardiovascular risk factors across five worldwide regions of the Seven Countries Study in predicting 50-year coronary deaths. A total of 13 cohorts of middle-aged men at entry (40-59 years old) were enrolled in the mid-1900s from five relatively homogeneous groups of cohorts (areas): USA, Finland and Zutphen - the Netherlands, Italy and Greece, Serbia, Japan for a total of 10,368 middle-aged men. The major risk factors measured at baseline were age, number of cigarettes smoked, systolic blood pressure and serum cholesterol. Cox proportional hazards models were solved for 50-year (45 years for Serbia) deaths from coronary heart disease (CHD), and the multivariable coefficients were compared for heterogeneity. The highest levels of risk factors and CHD death rates were found in Finland and Zutphen - the Netherlands and the lowest in Japan. All four risk factors were predictive for long-term CHD mortality in all regions, except serum cholesterol in Japan where the mean levels and CHD events were lowest. Tests of heterogeneity of coefficients for single risk factors in predicting CHD mortality were non-significant across the five areas. The same analyses for the first 25 years of follow-up produced similar findings. The strength of the multivariable associations of four major traditional CHD risk factors with long-term CHD mortality appears to be relatively homogeneous across areas, pending needed further evidence.

    Grading of essential hypertension according to blood pressure (BP) level may not adequately reflect clinical heterogeneity of hypertensive patients. This study was carried out to explore clinical phenotypes in essential hypertensive patients using cluster analysis. This study recruited 513 hypertensive patients and evaluated BP variations with ambulatory blood pressure monitoring. Four distinct hypertension groups were identified using cluster analysis: (1) younger male smokers with relatively high BP had the most severe carotid plaque thickness but no coronary artery disease (CAD); (2) older women with relatively low diastolic BP had more diabetes; (3) non-smokers with a low systolic BP level had neither diabetes nor CAD; (4) hypertensive patients with BP reverse dipping were most likely to have CAD but had least severe carotid plaque thickness. In binary logistic analysis, reverse dipping was significantly associated with prevalence of CAD. Cluster analysis was shown to be a feasible approach for investigating the heterogeneity of essential hypertension in clinical studies. BP reverse dipping might be valuable for prediction of CAD in hypertensive patients when compared with carotid plaque thickness. However, large-scale prospective trials with more information of plaque morphology are necessary to further compare the predicative power between BP dipping pattern and carotid plaque.

    Blood pressure was measured in the prospective randomized Special Turku Coronary Risk Factor Intervention Project Study with an oscillometric method every year from 7 months to 15 years of age in 540 children receiving a low-saturated-fat, low-cholesterol diet and in 522 control children. Dietary intakes, family history of parental hypertension, and grandparental vascular disease were recorded. Systolic and diastolic blood pressures were 1.0 mm Hg lower (95% CI for systolic: -1.7 to -0.2 mm Hg; 95% CI for diastolic: -1.5 to -0.4 mm Hg) in children receiving low-saturated-fat counseling through childhood than in control children. Intakes of saturated fat were lower (Pfat higher (Pcardiovascular or cerebrovascular disease, tended to be higher than that of children with no grandparental disease (P=0.051). We conclude that restriction of saturated fat from infancy until 15 years of age decreases childhood and adolescent blood pressure with a meaningful population-attributable amount. The importance of childhood lifestyle counseling and primary prevention of hypertension should be emphasized, especially in those children with a family history of hypertension or atherosclerotic vascular disease.

    There is a paucity of data on the temporal trends of cardiovascular risk factors in patients undergoing percutaneous coronary intervention (PCI). We investigated the secular trends of risk profiles of patients undergoing PCI without prior history of cardiovascular disease (CVD). CVD risk factors are changed over time. This time-trend analysis from 1994 to 2010 was performed within the Mayo Clinic PCI Registry. Outcome measures were prevalence of CVD risk factors, including the Framingham risk score (FRS), at the time of admission for PCI. During this period, 12,055 patients without a history of CVD (mean age, 65.0 ± 12.4 years, 67% male) underwent PCI at the Mayo Clinic. Age distribution slightly shifted toward older age (P for trend trend trend trend trend <0.001), whereas smoking prevalence did not change. The current study demonstrates that although traditional FRS and its associated predicted 10-year cardiovascular risk declined over time, the prevalence of risk factors increased in patients undergoing PCI. The study suggests the need for a new risk-factor assessment in this patient population. © 2014 Wiley Periodicals, Inc.

    Diabetes mellitus is recognized an independent risk factor for coronary artery disease (CAD) and mortality. Clinical trials have shown that statins significantly reduce cardiovascular events in diabetic patients. However, residual cardiovascular risk persists despite the achievement of target low-density lipoprotein cholesterol (LDL-C) levels with statin. High-density lipoprotein cholesterol (HDL-C) is an established coronary risk factor that is independent of LDL-C levels. We evaluated the impact of HDL-C on long-term mortality in diabetic patients with stable CAD who achieved optimal LDL-C. We enrolled 438 consecutive diabetic patients who were scheduled for percutaneous coronary intervention between 2004 and 2007 at our institution. We identified 165 patients who achieved target LDL-C diabetic patients with low-HDL-C who achieved optimal LDL-C (6.9 vs 17.9 %, log-rank P = 0.030). Multivariate Cox regression analysis showed that HDL-C is significantly associated with clinical outcomes (adjusted hazard ratio for MACE 1.33, 95 % confidence interval 1.01-1.75, P = 0.042). Low HDL-C is a residual risk factor that is significantly associated with long-term clinical outcomes among diabetic patients with stable CAD who achieve optimal LDL-C levels.

    STRUCTURED ABSTRACT Objectives To determine whether presentation, risk assessment, testing choices, and results differ by sex in stable symptomatic outpatients with suspected coronary artery disease (CAD). Background Although established CAD presentations differ by sex, little is known about stable, suspected CAD. Methods Characteristics of 10,003 men and women in the Prospective Multicenter Imaging Study for Evaluation of Chest Pain (PROMISE) trial were compared using chi-square and Wilcoxon rank sum tests. Sex differences in test selection and predictors of test positivity were examined using logistic regression. Results Women were older (62.4 years vs. 59.0) and more likely to be hypertensive (66.6% vs. 63.2%), dyslipidemic (68.9% vs. 66.3%), and to have a family history of premature CAD (34.6% vs. 29.3) (all p-values<0.005). Women were less likely to smoke (45.6% vs. 57.0%; p<0.001), while diabetes prevalence was similar (21.8% vs. 21.0%; p=0.30). Chest pain was the primary symptom in 73.2% of women vs. 72.3% of men (p=0.30) and was characterized as “crushing/pressure/squeezing/tightness” in 52.5% of women vs. 46.2% of men (p<0.001). Compared to men, all risk scores characterized women as lower risk, and providers were more likely to characterize women as having low (<30%) pre-test probability for CAD (40.7% vs. 34.1%; p<0.001). Compared with men, women were more often referred to imaging tests (adjusted OR 1.21; 95% CI 1.01–1.44) than non-imaging tests. Women were less likely to have a positive test (9.7% vs. 15.1%; p<0.001). Although univariate predictors of test positivity were similar, in multivariable models, age, BMI, and Framingham risk score were predictive of a positive test in women, while Framingham and Diamond and Forrester risk scores were predictive in men. Conclusion Patient sex influences the entire diagnostic pathway for possible CAD, from baseline risk factors and presentation to noninvasive test outcomes. These differences highlight the

    were interview and documentary observation, and the studied variables were age, sex, risk factors, and number of risk factors. In the analysis and processing of information a database and a SPSS statistical package were used. Average, and percentage were relative frequencies used as summary measures, and the statistical analysis was made by using independence X 2 test and odds ratio. The risk factors identified in the study group were previous family pathological history, high blood pressure, and obesity with 74.39 %, 64.63 %, and 57.31 %, respectively. In the control group, the risk factors were diabetes mellitus, previous family pathological history, and obesity with 44.71 %, 33.33 %, and 31.70 %. It was possible to identify in the study group the presence of three risk factors in 42 patients for 51.21 %, and four or more in 34.15%. It was concluded that high blood pressure, smoking, sedentarism, obesity, hypercholesterolemia, and previous family pathological history are significant risk factors for the development of cardiovascular diseases among the inhabitants of Hattieville, and that time and intensity of the exposure to the risk factor favoured the development of the disease.

    Recently neurologic complications after coronary artery bypass grafting (CABG) have received increasing attention. There is no detailed report about the risk factors for these complications, although stenosis in the cervical and intracranial arteries, especially in Japanese patients, latent ischemic brain lesions and preoperative neurological conditions are related to these events. In this prospective study, we evaluated occlusive lesions in the cervical carotid and intracranial arteries, silent brain infarction and cerebral deep white matter lesion with MRA and MRI in patients scheduled to undergo CABG to determine the prevalence of occlusive diseases in cervical carotid and intracranial arteries, latent ischemic change in the brain in this population and to identify preoperative risk factors for these patients. The subjects were 144 consecutive patients (103 men and 41 women, mean age 65.9{+-}9.2 years old) who were scheduled for CABG under elective conditions and who were examined by the same MRI apparatus using the same protocol between November 1998 and March 2001. After routine neurological examination and Mini-Mental State Examination (MMSE) were completed, MRI and MRA were obtained, then the prevalence of abnormalities on MRI and MRA studies and risk factors were evaluated. Cervical carotid artery stenosis with {>=}50% luminal narrowing was detected in 29.2% of the subjects, and that with {>=}75% luminal narrowing was detected in 16.0% of the subjects. Intracranial arterial stenosis showing {>=}50% luminal narrowing was detected in 38.2% of subjects, and that showing {>=}75% luminal narrowing was detected in 19.4% of subjects. Brain infarction was observed in 74.3% of subjects, cerebral deep white matter lesion showing grade 2 or higher on Fazekas classification was observed in 17.4% of the subjects. The characteristics, including possible risk factors of subjects with and without these abnormal findings, were compared. Patients with cervical carotid

    Epidemiologic evidence suggests that 8,368 kJ or 2000 kcal per week of moderate physical activity, including walking and stair climbing, can reduce risk of coronary heart disease (CHD). The goal of this study was to assess the effects of this amount of these two activities on physical fitness and risk factors for CHD. Twenty-two healthy, slightly overweight, sedentary, normotensive, normolipemic men, age 22 to 44 years, were randomly assigned to an exercise or control group for 12 weeks followed by a 4-week washout period. The subjects then were crossed-over to the alternate group for an additional 12-week period. Exercise consisted of 5 days per week of supervised treadmill exercise plus stair climbing. Treadmill exercise consisted of walking for 45 minutes at 5.15 km per hour at 2% grade for a total of 19.3 km per week. Subjects also climbed 10 floors of stairs at a time at their own pace without prescribed target heart rates for a total of 50 floors per week. The estimated total weekly energy cost of the treadmill walking plus stair climbing was 8,368 kJ or 2,000 kcal. Mean observed heart rates were 55% and 82% of maximal heart rate during treadmill walking and stair climbing, respectively. Data from the two exercise periods and two control periods were pooled and compared by analysis of variance. Sixteen subjects completed all phases of the study. Maximal oxygen uptake (VO2max) by the Bruce treadmill exercise protocol with metabolic gas measurements was below average for age at baseline, and was not significantly affected by 12 weeks of training. No significant changes were noted between groups in body weight or percent body fat (hydrostatic weighing), although there was a trend for loss of weight and fat with exercise training. Mean systolic blood pressure (119 mm Hg) was unchanged in both groups. However, diastolic blood pressure (72 mm Hg and 78 mm Hg for the treatment and control groups, respectively) showed an unexpected 6 mm Hg increase during the

    Full Text Available Impaired fasting glucose identifies individuals at high risk of progression to diabetes but the role of IFG as a coronary artery disease risk factor, independent of its progression to diabetes and its association with other coronary artery disease risk factors ,is unclear. A cross-sectional study was conducted to evaluate the hypothesis that impaired fasting glucose increased the likelihood of atherosclerotic plaque formation. Blood chemistry data as well as traditional coronary artery disease risk factors from 812 patients referred for coronary angiography to heart centers in Shahid- Chamran and Sina hospital, Isfahan, Iran were recorded. The population were stratified into three groups according to American Diabetes Association criteria: normal fasting glucose (n=608, impaired fasting glucose(n=92 and diabetes mellitus(n=112.We use extent, Vessel and stenosis scores to indicate the coronary artery involvement. KrusKal-Wallis test showed that the means of extent, Vessel and stenosis scores are not significantly different between three groups(P> 0.05. Multivariate linear regression analysis, using extent score of coronary artery disease as dependent variable and traditional risk factors and impaired fasting glucose as independent variables did not show any significant difference either. Our data suggested that impaired fasting glucose is not associated with increased risk of coronary atherosclerosis.

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

    The EUROASPIRE (European Action on Secondary and Primary Prevention by Intervention to Reduce Events) cross-sectional surveys describe time trends in lifestyle and risk factor control among coronary patients between 1999 and 2013 in Belgium, Czech Republic, Finland, France, Ireland, the Netherlands, Poland, Slovenia, and the United Kingdom as part of the EuroObservational Research Programme under the auspices of European Society of Cardiology. This study sought to describe time trends in lifestyle, risk factor control, and the use of evidence-based medication in coronary patients across Europe. The EUROASPIRE II (1999 to 2000), III (2006 to 2007), and IV (2012 to 13) surveys were conducted in the same geographical areas and selected hospitals in each country. Consecutive patients (≤70 years) after coronary artery bypass graft, percutaneous coronary intervention, or an acute coronary syndrome identified from hospital records were interviewed and examined ≥6 months later with standardized methods. Of 12,775 identified coronary patients, 8,456 (66.2%) were interviewed. Proportion of current smokers was similar across the 3 surveys. Prevalence of obesity increased by 7%. The prevalence of raised blood pressure (≥140/90 mm Hg or ≥140/80 mm Hg with diabetes) dropped by 8% from EUROASPIRE III to IV, and therapeutic control of blood pressure improved with 55% of patients below target in IV. The prevalence of low-density lipoprotein cholesterol ≥2.5 mmol/l decreased by 44%. In EUROASPIRE IV, 75% were above the target low-density lipoprotein cholesterol medications increased between the EUROASPIRE II and III surveys, but did not change between the III and IV surveys. Lifestyle habits have deteriorated over time with increases in obesity, central obesity, and diabetes and stagnating rates of persistent smoking. Although blood pressure and lipid management improved, they are still not optimally controlled and the use of evidence-based medications appears to have

    ObjectiveToinvestigate whether depression, anxiety and stress increase the risk for delirium and poor quality of life (QOL) after co-ronary artery bypass (CABG) surgery.MethodsA total of 180 CABG patients (mean age of 63.5 ± 10.1 years, 82.2% males) completed baseline and postoperative self-report questionnaires to assess distress and QOL. Incident delirium was diagnosed postoperatively with a structured clinical interview and patients were monitored every day post-operatively for confusion and disturbance in consciousness.Results Delirium developed in 63 persons (35% of sample). After adjustment for covariates, delirium was significantly associated with depression [odds ratio (OR): 1.08; 95% confidence interval (CI): 1.03–1.13,P = 0.003], anxiety (OR: 1.07; 95% CI: 1.02–1.13,P= 0.01) and stress (OR: 1.05; 95% CI: 1.00–1.09,P= 0.03). Preoperative depression scores were associated with poorer QOL including bodily pain (β =-0.39,P = 0.013), vitality (β=-0.32,P = 0.020), social functioning (β=-0.51,P£0.001), emotional role function (β=-0.44,P = 0.003) and general health (β=-0.33,P = 0.038). Among the covariates, harmful levels of alcohol use was consistently associated with poorer QOL.Conclusions Depression and harmful levels of alcohol use were consistently associated with poorer QOL whereas depression, anxiety and stress were associated with delirium risk. These findings point to further research examining depression and harmful levels of alcohol use in coronary heart disease populations undergoing coronary revascularization.

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

    Full Text Available Although heart surgery is one of the most effective methods in treating cardiovascular diseases, more than 50% of patients have problems in personal, social, professional adaptation after surgery (Pogosova, 1996. According to recent studies, psychological factors contribute significantly to negative outcomes of coronary surgery. The main factors are: depression, anxiety, personal factors and character traits, social isolation, and chronic life stress (Blumental, 2003; Connerney, 2010; Contrada, 2008; Cserep, 2010, Gallagher, 2007; Hoyer, 2008; Pigney-Demaria, 2003; Rozancki, 1999; Rymaszewska, 2003; Viars, 2009, Zaitsev, 1997. The aim of the article is to describe the association between psychological factors and the outcomes of coronary surgery. We have studied how the patient’s attitude towards forthcoming open heart surgery is associated with the outcomes. We have picked out four types of attitude towards forthcoming heart surgery: 1 pessimistic (no belief in recovery, surgery is threatening, damaging, 2 indifferent (no belief in recovery, surgery will not change anything, 3 optimistic but not realistic (exaggerated expectations, belief in full recovery, 4 optimistic and realistic (adequate expectations, belief in improvement. The study has shown that patients with optimistic-realistic attitudes towards forthcoming heart surgery have better outcomes, better emotional status, and shorter stays in hospital.

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

    Understanding the determinants of persistent smoking after a coronary event constitutes the basis of modelling interventions of smoking cessation in secondary prevention programs. We aim to identify the potentially modifiable medical, sociodemographic and psychosocial factors, comprising the study factors, associated with unfavourable risk factor control after CHD events. A cross-sectional explorative study used logistic regression analysis to investigate the association between study factors and smoking status in 1083 patients hospitalized with myocardial infarction and/or coronary revascularization. Hospital record data, a self-report questionnaire, clinical examination and blood samples were applied. At the index hospitalization, 390 patients were smoking and at follow-up after 2-36 months 167 (43%) of these had quit, while 230 reported persistent smoking. In adjusted analyses, unemployed or disability benefits (Odds ratio (OR) 4.1), low education (OR 3.5), longer smoking duration (OR 2.3) and not having ST-elevation myocardial infarction (STEMI) as index event (OR 2.3) were significantly associated with persistent smoking. Psychosocial factors at follow-up were not associated with persistent smoking. Smokers reported high motivation for cessation, with 68% wanting help to quit. Only 42% had been offered nicotine replacement therapy or other cessation aids. Smokers rated use of tobacco as the most important cause of their coronary disease (6.8 on a 1-10 Likert scale). Low socioeconomic status, prior duration of smoking, and not having STEMI as index event were associated with persisting smoking. Persistent smokers in this study seem to have an acceptable risk perception and were motivated to cease smoking, but needed assistance through cessation programs including prescription of pharmacological aids.

    This study was done in order to evaluate the effect of serum levels of total cholesterol, triglycerides, low-density lipoprotein-cholesterol and high-density lipoprotein-cholesterol on 10-year coronary heart disease risk distribution change. This study included 110 subjects of both genders (71 female and 39 male), aged 29 to 73, treated at the Outpatient Department of Atherosclerosis Prevention, Centre for Laboratory Medicine, Clinical Centre Vojvodina. The 10-year coronary heart disease risk was estimated on first examination and after one-year treatment by means of Framingham, PROCAM and SCORE coronary risk scores and their modifications (Framingham Adult Treatment Panel III, Framingham Weibul, PROCAM NS and PROCAM Cox Hazards). Age, gender, systolic and diastolic blood pressure, smoking, positive family history and left ventricular hypertrophy are risk factors involved in the estimation of coronary heart disease besides lipid parameters. There were no significant differences in nutritional status, smoking habits, systolic and diastolic pressure, and no development of diabetes mellitus or cardiovascular incidents during one-year follow. However, a significant reduction in cholesterol level (p risk (Framingham- p Framingham ATP III- p Framingham Weibul- p SCORE- p risk category (Framingham- p Framingham ATP III- p Framingham Weibul- p SCORE- p risk at the beginning of the study. Our results show that the correction of lipid level after one-year treatment leads to a significant redistribution of 10-year coronary heart disease risk estimated by means of seven different coronary risk scores. This should stimulate patients and doctors to persist in prevention measures.

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

    Coronary artery disease (CAD) often leads to myocardial infarction, which may be fatal. Risk factors can be used to predict CAD, which may subsequently lead to prevention or early intervention. Patient data such as co-morbidities, medication history, social history and family history are required to determine the risk factors for a disease. However, risk factor data are usually embedded in unstructured clinical narratives if the data is not collected specifically for risk assessment purposes. Clinical text mining can be used to extract data related to risk factors from unstructured clinical notes. This study presents methods to extract Framingham risk factors from unstructured electronic health records using clinical text mining and to calculate 10-year coronary artery disease risk scores in a cohort of diabetic patients. We developed a rule-based system to extract risk factors: age, gender, total cholesterol, HDL-C, blood pressure, diabetes history and smoking history. The results showed that the output from the text mining system was reliable, but there was a significant amount of missing data to calculate the Framingham risk score. A systematic approach for understanding missing data was followed by implementation of imputation strategies. An analysis of the 10-year Framingham risk scores for coronary artery disease in this cohort has shown that the majority of the diabetic patients are at moderate risk of CAD.

    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.

    Subclinical atherosclerosis can be quantified by coronary artery calcium (CAC) scoring. Due to its high specificity for atherosclerosis, CAC is an excellent phenotypic tool for the evaluation of emerging risk markers. Lipoprotein(a) [Lp(a)] is atherogenic due to the presence of apoB and may be thrombogenic through its apo(a) component. Lp(a) has been linked to cardiovascular events in Caucasians; however, its link to atherosclerosis in various ethnicities remains unclear. We evaluated the ability of Lp(a) mass to predict subclinical atherosclerosis in Southeast Asians and Caucasians, as measured by CAC. Traditional lipid measurements, Lp(a) measurements, and CAC by 64-slice multidetector computed tomography was performed in 103 consecutive patients in the USA and in 104 consecutive patients in Jakarta, Indonesia. Proportion of positive CAC and median CAC in Southeast Asians and in Caucasians was 61.5% and 63.1%, and 23.5 (interquartile range, 0-270) and 13 (interquartile range, 0-388), respectively. Significantly higher proportion of Southeast Asians had elevated Lp(a) levels, compared to Caucasians (51.0% vs. 29.2%; p = 0.005). In Southeast Asians, Lp(a) remained an independent predictor of CAC with an odds ratio of 4.97 (95% confidence interval, 1.56-15.88; p Southeast Asians. This translated to 7% of Southeast Asians reclassified to correct CAC status. Lp(a) measurements may have a role in risk stratification of Southeast Asians. Ethnic variation should be taken into account when considering the use of Lp(a) measurements in risk assessment.

    Full Text Available Abstract Background Coronary artery disease is the leading cause of morbidity and mortality in patients with type 2 diabetes. Screening for asymptomatic coronary artery disease with treatment by means of revascularization seems to be an appealing option for prevention. The utility of such a strategy has never been challenged in a randomized trial. Methods/Design In the present study a cohort of diabetic patients without any symptoms and without known coronary artery disease will be screened at two diabetes outpatients services. Those with intermediate or high risk (equal or greater than 10% according to the Italian risk chart will be asked to participate and enrolled. They will be seen and followed in order to provide the best adherence to medical therapy. Half of the patients will be randomized to undergo an exercise tolerance testing while the other group will continue to be regularly seen at diabetes outpatients services. Best medical/behavioral therapy will be offered to both groups. Those patients with a positive exercise tolerance testing will be studied by coronary angiography and treated according to the severity of coronary lesions by percutaneous stenting or surgery. The objective of the study is to evaluate the efficacy of the screening strategy aimed at revascularization. A cost-effectiveness analysis will be performed at the end of the follow up. Discussion The study will provide useful information about prevention and treatment of diabetic patients at high risk of coronary events. It will be made clearer if detection of silent coronary artery disease has to be recommended and followed by treatment. Given the simplicity of the study protocol, it will be easily transferable to the real world. Trial registration (ClinicalTrials.gov: NCT00547872

    Background: CT angiography (CTA) plays an important role in diagnosing coronary arterial disease. Delay time and density of the coronary arteries related with patient-specific factors are essential for getting an optimal CTA image. Purpose: To investigate various factors influencing delay time and coronary arterial density during coronary CTA with dual source CT. Material and Methods: One hundred and sixteen consecutive subjects who underwent cardiac DSCT with retrospective ECG-gating were included. Factors including gender, age, height, weight, transversal cardiac diameter (TCD), transversal thoracic diameter (TTD), heart rate (HR), body surface area (BSA = [weight x height/3600]1/2) and cardiothoracic ratio (CTR = TCD/TTD) were recorded, measured and calculated before administration of contrast media during coronary CT angiography. Delay time was determined as duration from the beginning of the injection to the density in the descending aorta at the level of right main pulmonary artery reaching a threshold of 100 HU. Coronary arterial density was measured at the mid portion of the right coronary artery. Regression analysis and stepwise regression analysis were used to investigate the influence of these factors on delay time and coronary arterial density. Results: Delay time decreased with an increasing HR and it was shorter in women than men. Delay time increased with an increasing TCD. Delay time could be predicted by the formula: DT = 16.651-0.110 x HR + 1.902 x gender + 0.394 x TCD (where DT is abbreviation for delay time, gender is 0 for women and 1 for men). Coronary arterial density decreased with an increasing HR and weight. Coronary arterial density could be predicted by the formula: CAD = 923.42-4.099 x HR-3.293 x weight (CAD = coronary arterial density). There was no relationship between the other factors mentioned above and delay time or coronary arterial density. Conclusion: Delay time is influenced by HR, gender and TCD. Coronary arterial density

    Objective To evaluate the correlation between multiple cardiovascular risk factors and severity of coronary heart disease (CHD) in patients undergoing coronary angiography. Methods Seven hundred and twenty eight patients who underwent coronary angiography were selected from Qilu Hospital from October 2008 to December 2009. The clinical data about cardiovascular risk factors including age, gender, hypertension, smoking status, type 2 diabetes mellitus, dyslipidemia, high uric acid level, low total bilirubin level, and coronary angiography results were collected. The severity and extent of coronary stenosis was evaluated by ACC/AHA coronary scoring system and CHD was diagnosed by angiography. Analyses were achieved by multiple regression analysis. Results Multiple regression analysis showed that age, gender, hypertension, type 2 diabetes mellitus and low HDL-C were prominent predictors of severity and extent of coronary heart disease. DM was the primary controllable risk factor of CHD (OR=3. 1179, P=0. 005). Conclusions The age, gender,hypertension, type 2 diabetes mellitus and low HDL-C are correlated with angiographic severity and extent of CHD. Consequently, controlling these five risk factors is important in the intervention and prevention of CHD.%目的 探讨心血管病危险因素与冠状动脉(冠脉)病变严重程度的相关性. 方法入选2008年10月至2009年12月在山东大学齐鲁医院行冠脉造影术的病例728例,收集其性别、年龄、吸烟史、高血压、糖尿病、总胆红素(TBIL)、血脂、尿酸等临床资料.同时收集患者冠脉造影结果,以美国心脏病学会和美国心脏协会(ACC/AHA)评分法计算冠脉病变积分,以冠脉病变积分及是否诊断为冠心病评价其冠状动脉病变程度.统计学处理采用多因素回归分析. 结果多因素回归分析结果显示,男性、年龄、高血压、糖尿病,高密度脂蛋白胆固醇这5个危险因素是影响冠脉病变积分主要的危险

    Full Text Available Background: Androgenetic alopecia (AGA or male pattern baldness (MPB has been found to be associated with the risk of coronary artery disease (CAD. The well-known risk factors are family history of CAD, hypertension, increased body mass index (BMI, central obesity, hyperglycemia, and dyslipidemia. The newer risk factors are serum lipoprotein-a (SL-a, serum homocysteine (SH, and serum adiponectin (SA. Aim : Identifying individuals at risk of CAD at an early age might help in preventing CAD and save life. Hence, a comparative study of CAD risk factors was planned in 100 males of AGA between the age of 25 and 40 years with equal number of age- and sex-matched controls. Materials and Methods : Patients of AGA grade II or more of Hamilton and Norwood (HN Scale and controls were examined clinically and advised blood test. The reports were available for fasting blood sugar (FBS, serum total serum cholesterol (SC in 64 cases, 64 controls; lipoproteins (high, low, very low density, HDL, LDL, VLDL, serum triglycerides (ST in 63 cases, 63 controls; SL-a in 63 cases, 74 controls; SH in 56 cases, 74 controls; and SA in 62 cases, 74 controls. Results : In these cases family history (FH of AGA and CAD was significantly high. The blood pressure (BP was also found to be significantly high in the cases. The difference of mean serum HDL, LDL, VLDL, ST, SH, and SL-a in cases and controls were statistically significant and with increasing grade of AGA, the risk factors also increased. Conclusion : Patients with AGA appear to be at an increased risk of developing CAD, therefore, clinical evaluation of cases with AGA of grade II and above may be of help in preventing CAD in future.

    Objective To evaluate values of non-invasive examinations plus clinical risk factors in auxiliary diagnosis of coronary heart disease. Methods The investigation was conducted in patients who had first undergone CAG from January 2001 through March 2007 in 20 top Chinese hospitals. In the auxiliary diagnosis of coronary heart disease, non-invasive examinations, including Holter, treadmill exercise test ( TET) , radionuclide myocardial perfusion imaging (MPI) ,multislice spiral computed tomography (MSCT) and their combinations, were used with additional consideration of common clinical risk factors. The sensitivities and specificities of different diagnostic strategies were determined in the auxiliary diagnosis of coronary heart disease. Results The sensitivities of different combinations of non-invasive examinations ranged from 56. 02% to 87. 43% , the specificities ranged from 36. 13% to 89. 66% ,the positive predictive rates ranged from 58. 83% to 97. 73% , and the negative predictive rates ranged from 30. 21% to 73. 36%. The addition of clinical risk factors into the auxiliary diagnosis was not found to improve the discrimination capability. Conclusion Combination of non-invasive examinations can be used as a basic and significant diagnostic method for coronary artery disease, particularly the combination of Holter and MSCT,in various levels of hospitals. Clinical risk factors may not contribute to the improved discrimination capability in auxiliary diagnosis of coronary heart disease.%目的 评价几种无创性检查联合临床危险因素对冠心病诊断的辅助价值.方法 选择2001年1月至2007年3月在全国20家三级甲等医院心内科住院疑诊冠心病并初次行诊断性冠状动脉造影(CAG)的患者.纳入常见的临床危险因素后,评价4种无创性检查(包括动态心电图、负荷心电图、负荷核素心肌显像、冠脉CT)及其组合对冠心病诊断的敏感度、特异度.结果 无创性检查组合在冠心

    To (1) report the prognostic association between anxiety disorder subtypes and major adverse cardiac events (MACE), (2) report anxiety disorder prevalence in coronary heart disease (CHD), and (3) report the efficacy of anxiety disorder treatments in CHD. A comprehensive electronic database search was performed in November 2013 for studies reporting anxiety disorder prevalence according to structured interview in CHD samples or MACE, and randomized controlled trials (RCTs) comparing anxiety disorder treatment with placebo or usual care. From 4041 articles 42 samples were selected for extraction (8 for MACE prognosis, 39 for prevalence, no RCTs were eligible). Five generalized anxiety disorder (GAD) studies reported 883 MACE events (combined n=2851). There was a non-significant association between GAD and MACE (risk ratio=1.20, 95% CI .86-1.68, P=.28) however the effect size was highly significant in outpatient samples (adjusted hazard ratio=1.94, 95% CI 1.45-2.60, Panxiety disorder subtype was associated with MACE. Prevalence data showed high comorbidity with depression (49.06%; 95% CI 34.28-64.01) and substantial heterogeneity between studies. Panic disorder prevalence was higher in psychiatrist/psychologist raters (9.92% vs. 4.74%) as was GAD (18.45% vs. 13.01%). Panic and GAD estimates were also heterogeneous according to DSM-III-R versus DSM-IV taxonomies. The paucity of extant anxiety disorder RCTs, alongside MACE risk for GAD outpatients, should stimulate further anxiety disorder intervention in CHD populations. Research should focus on depression and anxiety, thereby unraveling disorder specific and more generic pathways. Copyright © 2014 Elsevier Inc. All rights reserved.

    Longstanding uncontrolled atherogenic risk factors may contribute to left atrial (LA) hypertension, LA enlargement (LAE) and coronary vascular dysfunction. Together they may better identify risk of major adverse cardiac events (MACE). The aim of this study was to test the hypothesis that chronic LA hypertension as assessed by LAE modifies the relationship between coronary vascular function and MACE. In 508 unselected subjects with a normal clinical {sup 82}Rb PET/CT, ejection fraction ≥40 %, no prior coronary artery disease, valve disease or atrial fibrillation, LAE was determined based on LA volumes estimated from the hybrid perfusion and CT transmission scan images and indexed to body surface area. Absolute myocardial blood flow and global coronary flow reserve (CFR) were calculated. Subjects were systematically followed-up for the primary end-point - MACE - a composite of all-cause death, myocardial infarction, hospitalization for heart failure, stroke, coronary artery disease progression or revascularization. During a median follow-up of 862 days, 65 of the subjects experienced a composite event. Compared with subjects with normal LA size, subjects with LAE showed significantly lower CFR (2.25 ± 0.83 vs. 1.95 ± 0.80, p = 0.01). LAE independently and incrementally predicted MACE even after accounting for clinical risk factors, medication use, stress left ventricular ejection fraction, stress left ventricular end-diastolic volume index and CFR (chi-squared statistic increased from 30.9 to 48.3; p = 0.001). Among subjects with normal CFR, those with LAE had significantly worse event-free survival (risk adjusted HR 5.4, 95 % CI 2.3 - 12.8, p < 0.0001). LAE and reduced CFR are related but distinct cardiovascular adaptations to atherogenic risk factors. LAE is a risk marker for MACE independent of clinical factors and left ventricular volumes; individuals with LAE may be at risk of MACE despite normal coronary vascular function. (orig.)

    Objective To investigate clinical risk factors and coronary angiographic features in young men with acute myocardial infarction (AMI).Methods We retrospectively studied 200 young men with AMI and compared with 104 non-CHD men,89 old men with AMI.All patients were admitted to hospital from January 2009 to December 2010 and undergone coronary angiography,and the clinic and coronary angiographic features were assessed.The relation between body mass index (BMI),smoking history,familial history of early coronary artery disease,essential hypertension,type 2 diabetes mellitus,hyperlipidemia,serum uric acid ( UA),lipids,hemoglobin (Hb),fasting blood glucose (FBG) with coronary artery disease and its severity was observed.The severity of CAD was diagnosed by the number of diseased vessel.Results In young men with AMI group,the factors such as smoking history,obesity,essential hypertension,type 2 diabetes mellitus,familial history of early coronary artery disease were remarkably different ( P < 0.05 ) ; body mass index,fasting blood glucose,total cholesterol,triglyceride,low density lipoprotein cholesterol were higher than the control group ( P < 0.05 ),hemoglobin was lower than the control group ( P < 0.05 ).Applying Logistic regression analysis,obesity ( OR =11.020),type 2 diabetes mellitus ( OR =5.805 ),essential hypertension ( OR =4.428 ),familial history of early coronary artery disease ( OR =2.883 ),smoking history ( OR =2.153 ) and lower concentration hemoglobin ( OR =1.034) are independent risk factors (P < 0.05) for young men with AMI. According to coronary angiography in young men with AMI,there were 14 cases with zero-vessel disease,109 cases with singlevessel disease (54.50%,69 cases involved with left anterior descending artery) and 42 cases with twovessel disease,35 cases with three-vessel disease.The ratio of single vessel disease involved left anterior desending artery in young men was higher than that of old men with AMI ( P < 0.05 ).Conclusions

    2006-05-01

    Full Text Available Background: In 2003 nearly 20% of deaths in Germany were caused by coronary heart disease (CHD. Risk models are used to estimate the ten-year-risk of a coronary event. Coronary calcification may be seen as an additional risk factor. The amount of calcium is correlated with atherosclerotic lesions, but there is no direct correlation with the probability of a plaque rupture. Coronary calcification may be measured either by electron beam computed tomography (EBCT or multi-detector computed tomography (MDCT. Objectives: The aim of this HTA report is to investigate the diagnostic validity and cost effectiveness of computed tomography techniques in measuring coronary calcification of asymptomatic risk patients. Ethical aspects are discussed. Methods: A systematic literature research was performed in 35 international databases which yielded 1080 articles. Overall 43 publications were included for assessment, according to predefined selection criteria. Results: Measuring coronary calcification offers additional information compared with traditional risk factors. Yet at present it cannot be said - according to published literature - which population groups gain most. For determining adequate calcium score thresholds standardisation for age and sex is important. When comparing the reference standard EBCT with MDCT results are inconsistent and depend on the calcium-score value as well as on the scoring method. EBCT as a triage instrument in diagnosing CHD appears to be cost-effective. Yet it is rather not cost-effective as a refinement tool for risk stratification. Discussion: Most of the literature was published in the United States and discusses the use of EBCT as well as (traditional risk stratification by the Framingham Score. Regarding coronary calcification measured by MDCT (which is more widespread in Germany than EBCT and a risk model applicable for European populations clear recommendations based on published literature cannot be made at present

    To test the hypothesis that abnormal hemorheology and chronic low-grade inflammation are more prevalent in Lewis negative individuals, possibly contributing to premature atherosclerosis. We enrolled 223 healthy subjects (154 females, mean age: 64yrs). Conventional risk factors, markers of inflammation and hemorheological profiles were measured; Lewis blood group was determined by serology. Conventional risk factors (age, gender, BMI, blood pressure, lipid profile, smoking habit) did not differ among Lewis phenotypes. However, markers of inflammation (WBC, hs-CRP, ESR) were significantly elevated and rheological parameters (RBC aggregation, plasma viscosity) were abnormal in Lewis negative subjects, especially when compared to the Le(a-b+) group. With a prevalence of 33% in select populations, our data support the hypothesis that Le(a-b-) represents a pro-inflammatory phenotype that may contribute to the elevated cardiovascular risk in this group.

  5. Coronary heart disease in women: why the disproportionate risk?

    Women with diabetes experience much greater relative risks of coronary heart disease (CHD) compared with the nondiabetic population than do men with diabetes. In type 2 diabetes, much of the greater elevation in risk in women is explained by a more adverse pattern of known CHD risk factors. In type 1 diabetes the picture is less clear, but current evidence suggests that a cardioprotective lipid profile is found in type 1 diabetic men, thus reducing the effect of diabetes on CHD, but that in women this is not the case. Also, in type 1 diabetic women there is some evidence of altered body fat distribution and a greater elevation in blood pressure. Whether these reflect a greater degree of insulin resistance in type 1 women, and what the origin of this might be, remains controversial. The practical consequence is that clinicians need to be aware that the usual cardioprotective effect of sex does not apply in diabetic women and that risk factor intervention is needed at an early age.

  6. The relationship between proteinuria and coronary risk: a systematic review and meta-analysis.

    Full Text Available BACKGROUND: Markers of kidney dysfunction such as proteinuria or albuminuria have been reported to be associated with coronary heart disease, but the consistency and strength of any such relationship has not been clearly defined. This lack of clarity has led to great uncertainty as to how proteinuria should be treated in the assessment and management of cardiovascular risk. We therefore undertook a systematic review of published cohort studies aiming to provide a reliable estimate of the strength of association between proteinuria and coronary heart disease. METHODS AND FINDINGS: A meta-analysis of cohort studies was conducted to obtain a summary estimate of the association between measures of proteinuria and coronary risk. MEDLINE and EMBASE were searched for studies reporting an age- or multivariate-adjusted estimate and standard error of the association between proteinuria and coronary heart disease. Studies were excluded if the majority of the study population had known glomerular disease or were the recipients of renal transplants. Two independent researchers extracted the estimates of association between proteinuria (total urinary protein >300 mg/d, microalbuminuria (urinary albumin 30-300 mg/d, macroalbuminuria (urinary albumin >300 mg/d, and risk of coronary disease from individual studies. These estimates were combined using a random-effects model. Sensitivity analyses were conducted to examine possible sources of heterogeneity in effect size. A total of 26 cohort studies were identified involving 169,949 individuals and 7,117 coronary events (27% fatal. The presence of proteinuria was associated with an approximate 50% increase in coronary risk (risk ratio 1.47, 95% confidence interval [CI] 1.23-1.74 after adjustment for known risk factors. For albuminuria, there was evidence of a dose-response relationship: individuals with microalbuminuria were at 50% greater risk of coronary heart disease (risk ratio 1.47, 95% CI 1.30-1.66 than

    Cardiovascular disease (CVD) is the leading cause of mortality and a major cause of morbidity. Coronary heart disease (CHD) accounts for nearly half of all CVD deaths. Currently estimation of risk in primary prevention is based on the Framingham risk equations, which inputs traditional risk factors and is helpful in predicting the development of CHD in asymptomatic individuals. However many individuals suffer events in the absence of established risk factors for atherosclerosis and broad based population risk estimations may have little precision when applied to a given individual. To meet the challenge of CHD risk assessment, several tools have been developed to identify atherosclerotic disease in its preclinical stages. This paper aims to incorporate information from coronary artery calcification (CAC) scoring from a computed tomographic "heartscan" (using Electron Beam Tomography (EBT) as the validated prototype) along with current Framingham risk profiling in order to refine risk on an absolute scale by combining imaging and clinical data to affect a more comprehensive calculation of absolute risk in a given individual. For CAC scores above the 75th percentile but or =55 years, women> or =65 years) a CAC = 0 will result in an age point score corresponding to the age-group whose median CAC score is zero i.e., 40-44 years for men and 55-59 years for women. The utilization of CAC scores allows the inclusion of sub-clinical disease definition into the context of modifiable risk factors as well as identifies high-risk individuals requiring aggressive treatment.

    Some recent research has suggested that health-related behaviours, such as smoking, might explain much of the socio-economic inequalities in coronary heart disease (CHD) risk. In a large prospective study of UK women, we investigated the associations between education and area deprivation and CHD risk and assessed the contributions of smoking, alcohol consumption, physical activity and body mass index (BMI) to these inequalities. After excluding women with heart disease, stroke or cancer at recruitment, 1,202,983 women aged 56 years (SD 5 years) on average, were followed for first coronary event (hospital admission or death) and for CHD mortality. Relative risks of CHD were estimated by Cox regression, and the extent to which any association could be accounted for by smoking, alcohol, physical inactivity, and BMI was assessed by calculating the percentage reduction in the relevant likelihood-ratio (LR) statistic after adjustment for these factors, separately and together. A total of 71,897 women had a first CHD event (hospital admission or death) and 6032 died from CHD during 12 years follow-up. In analyses adjusted by age, birth cohort and region of residence only, lower levels of education and greater deprivation were associated with higher risks of CHD (P heterogeneity deprivation and for deprivation were found within every level of education. Smoking, alcohol consumption, physical inactivity and BMI accounted for most of the associations (adjustment for all four factors together reduced the LR statistics for education and for deprivation by 76 % and 71 %, respectively, for first CHD event; and by 87 % and 79 %, respectively, for CHD mortality). Of these four factors, adjustment for smoking resulted in the largest reduction in the LR statistic. Given the large reduction in the predictive values of education and deprivation after adjustment for only four health-related behavioural factors recorded just at recruitment, residual confounding might plausibly

    Diabetic women have a greater relative risk of coronary heart disease than diabetic men. However, the sex difference in the effect of fasting serum glucose levels below the diabetic range on the risk of coronary heart disease is unclear. We investigated whether the association between nondiabetic blood glucose levels and the incident risk of coronary heart disease is different between men and women. The fasting serum glucose levels and other cardiovascular risk factors at baseline were measured in 159,702 subjects (100,144 men and 59,558 women). Primary outcomes were hospital admission and death due to coronary heart disease during the 11-year follow-up. The risk for coronary heart disease in women significantly increased with impaired fasting glucose levels (≥110mg/dL) compared to normal glucose levels (coronary heart disease in men was significantly increased at a diabetic glucose range (≥126mg/dL). Women had a higher hazard ratio of coronary heart disease associated with the fasting serum glucose level than men (p for interaction with sex=0.021). The stronger effect of the fasting serum glucose levels on the risk of coronary heart disease in women than in men was significant from a prediabetic range (≥110mg/dL).

    2011-01-01

    Objective: To investigate the risk factors and the coronary angiographic findings in young adults with acute myocardial infarction( AMI ). Methods:The AMI patients under the age of 40 were defined as youth group( n =48 ) and those above 40 as midelderly group( n = 50 ). The clinical data( risk factors and coronary angiographic findings ) of both groups were collected and compared.Results:The incidence of AMI was 97.97% in the male patients in the youth group,while it was 82.00% in the mid-elderly group ( P <0.05 ). The youth group had a lower proportion of hypertension( 19.00% vs 60.00% ,P <0.01 ),and a higher proportion of non"three highs"( hypertension,diabetes mellitus,dyslipidemia )( 67.00% vs 30.00%, P < 0.01 ) as compared with the mid-elderly group. The proportion of patients with smoking as the only risk factor accounted for 52.00% in the youth group, while it was only 6.00% in the mid-elderly group. Among the six AMI cases with no "three highs" or smoking history in the youth group,3 were proved to have a family history of early-attacking cardiovascular disease, 1 had atheroembolism and 2 had unknown reasons. The youth group had a higher proportion of single coronary artery lesions( 46.00% vs 20.00%, P < 0.01 ) and lower proportion of multiple branch lesions( 52.00% vs 78.00% ,P < 0.01 ) than the mid-elderly group. Conclusions:Most of the young AMI patients are male, presenting no "three highs" ;smoking is usually the only risk factor. And the young patients who do not have "three highs" or smoke usually have a family history of early-attacking cardiovascular disease. Compared with the mid-elderly, most of the young AMI patients suffer from single coronary vessel disease.%目的:探讨青年人急性心肌梗死的危险因素及冠状动脉病变特点.方法:将48例年龄≤40岁的急性心肌梗死患者列为青年组,50例年龄>40岁的急性心肌梗死患者列为中老年组,比较并分析2组冠心病危险因

    Full Text Available Cardiovascular disease has emerged as a crescent problem among HIV-infected population. This study aimed to determine the 10-year risk of coronary heart disease using the Framingham risk score among HIV-infected patients from three regions of Brazil. This is a pooled analysis of three cohort studies, which enrolled 3,829 individuals, 59% were men, 66% had white skin color, and mean age 39.0 ± 9.9 years. Comparisons among regions showed that there were marked differences in demographic, socioeconomic, clinical, and HIV-related characteristics. Prevalence of Framingham score ≥10 was 4.5% in the Southern, 4.2% in the Midwest, and 3.9% in the Northeast of Brazil. The Framingham score ≥10 was similar between regions for males, patients aged ≥60 years, with obesity, central obesity, hypertension, and diabetes mellitus. Women were three times more likely to have coronary heart disease in 10 years than men. Hypertension and diabetes increased more than four times the risk of coronary heart disease, followed by central obesity, obesity, and prehypertension. The use of antiretroviral agents and time since HIV diagnosis were not risk factors for coronary artery disease in 10 years. In conclusion, hypertension and diabetes are the strongest independent predictors of 10-year risk of coronary heart disease among HIV-infected population.

    2006-01-01

    The association of elevated serum uric acid (hyperuricemia, gout) with the presence of classical coronary risk factors and coronary artery disease (CAD) or myocardial infarction (MI) has been analysed in many epidemiological studies. Numerous studies have revealed that hypertension, high body mass index (BMI), lipid disorders (especially raised triglycerides--TG level and low high dense lipoprotein cholesterol HDL-C level), increased creatinine or insulin levels have caused hyperuricemia. No association has been observed between hyperuricemia and diabetes type 2 and uricemia and glicemia. But in some studies the relationship between cholesterol and uric acid levels has been not confirmed. Hyperuricemia has been observed in patients with non-treated hypertension. Gout has often occurred with typical disorders for the metabolic syndrome X. Significant correlation of the serum uric level and the CAD presence and severity of coronary atherosclerosis confirmed by coronary angiography has been observed in women. Hyperuricemia has also indirect influence on progress of CAD by physical activity restriction, what causes sedentary mode of life and lead to obesity. Obesity is a known risk factor diabetes, lipid disorders and hypertension. To recapitulate, it is a matter of controversy as to whether uric acid is an independent cardiovascular risk factor or rather it only represents reinforcement of typical risk factor.

    The obesity epidemic is associated with a rise in coronary surgeries because obesity is a risk factor for coronary artery disease. Bariatric surgery is linked to improvement in cardiovascular co-morbidities and left ventricular function. No studies have investigated survival advantage in postoperative bariatric patients after coronary surgery. To determine if there is a benefit after coronary surgery in patients who have previously undergone bariatric surgery. National Inpatient Sample. We performed a retrospective, cross-sectional analysis of the National Inpatient Sample database from 2003 to 2010. We selected bariatric surgical patients who later underwent coronary surgery (n = 257). A comparison of postoperative complications and mortality after coronary surgery were compared with controls (n = 1442) using χ(2) tests, linear regression analysis, and multivariate logistical regression models. A subset population was identified as having undergone coronary surgery (n = 1699); of this population, 257 patients had previously undergone bariatric surgery. They were compared with 1442 controls. The majority was male (67.2%), white (82.6%), and treated in an urban environment (96.8%). Patients with bariatric surgery assumed the risk of postoperative complications after coronary surgery that was associated with their new body mass index (BMI) (BMI999.9, 95% CI .18 to>999.9, P = .07). Length of stay was significantly longer in postbariatric patients (BMIbariatric patients have a return to baseline risk of morbidity and mortality after coronary surgery.

    1998-11-26

    Vigorous cholesterol lowering with diet, drugs, or a combination has been shown to slow, arrest, or even reverse atherosclerosis. Residential lifestyle intervention programs have successfully lowered serum cholesterol levels and other coronary risk factors, but they have the disadvantages of high cost and difficulty with long-term adherence. Community-based risk-reduction programs have the potential to effect change at low cost and improve long-term adherence. To assess the effectiveness of, and to develop a model for, such programs, the community-based Coronary Health Improvement Project (CHIP) was developed in Kalamazoo, Michigan. In the intensive (30-day, 40-hour), hospital-based educational program, participants are encouraged to exercise 30 minutes a day and to embrace a largely unrefined plant-food-centered diet that is high in complex carbohydrates and fiber; very low in fat, animal protein, sugar, and salt; and virtually free of cholesterol. A total of 304 enrollees in the first program were at elevated risk of coronary artery and related diseases: 70% were > or =10% above their ideal weight, 14% had diabetes, 47% had hypertension, and 32% had a history of coronary artery disease. Of the enrollees, 288 "graduated" from the program (123 men, 165 women; mean age was 55+/-11 years). Various markers of disease risk, including serum blood lipids and fasting blood glucose concentrations, were measured before and after the program. At 4 weeks, overall improvements in the participants' laboratory test results, blood pressures, weights, and body mass indexes were highly significant (p 200 mg/dL in men, 200-299 mg/dL in women).

    2012-06-01

    Full Text Available Abstract Background Cardiovascular disease (CVD is the leading cause of death worldwide. Secondary prevention is essential, but participation rates for cardiac rehabilitation are low. Furthermore, current programmes do not accomplish that patients with CVD change their lifestyle in a way that their individual risk factors for recurrent events decrease, therefore more effective interventions are needed. In this study, the effectiveness of the Hartcoach-programme, a telephonic secondary prevention program focussing on self management, is studied. Methods/design A multicenter, randomised parallel-group study is being conducted. Participants are 400 patients with acute myocardial infarction (STEMI, NSTEMI, and patients with chronic or unstable angina pectoris (IAP. Patients are recruited through the participating hospitals and randomly assigned to the experimental group (Hartcoach-programme plus usual care or the control group (usual care. The Hartcoach-programme consists of a period of six months during which the coach contacts the patient every four to six weeks by telephone. Coaches train patients to take responsibility for the achievement and maintenance of the defined target levels for their particular individual modifiable risk factors. Target levels and treatment goals are agreed by the nurse and patient together. Data collection is blinded and occurs at baseline and after 26 weeks (post-intervention. Primary outcome is change in cardiovascular risk factors (cholesterol, body mass index, waist circumference, blood pressure, physical activity and diet. Secondary outcomes include chances in glucose, HbA1c, medication adherence, self-management and quality of life. Discussion This study evaluates the effects of the Hartcoach-programme on the reduction of individual risk factors of patients with CVDs. Patients who are not invited to follow a hospital based rehabilitation programme or patients who are unable to adhere to such a programme, may be

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

    This study devoted to specific features of coronary heart disease (CHD) development in emergency work ers (EW) of the accident at the Chernobyl nuclear power plant (ChNPP) based on analysis the interaction between radiation and non radiation risk factors and single nucleotide polymorphism (SNP) rs966221 of phosphodiesterase (PDE) 4D gene. It was examined 397 men with CHD, including 274 EW of 1986-1987 and 123 non irradiated persons (con trol group) who were 66±10 and 69±11 years old relatively. The program studies included clinical examination, elec trocardiography (ECG), ECG daily monitoring, ECG stress testing, echo doppler cardiography, analysis of serum lipid spectrum, polymerase chain reaction with restriction of reaction products, retrospective analysis of case histories. Diagnosis of CHD or its approval was carried out in accordance with the standards of diagnosis, accepted in Ukraine. All EW before their taking part in cleaning ChNPP territory did not suffered from CHD. According to the analysis of contingency tables, carriers of the TT genotype of rs966221 increased the risk of myocardial infarction (MI) in 2.538 times compared with carriers of genotypes CC and CT. The use of Kaplan Meier method showed that a half of EW with the TT genotype developed MI before 64 years old, while with the other geno types up to 78.7 years old. In the control group statistically significant increase of cumulative proportion of patients with MI, carriers of the TT genotype, began from 60 years old. Compared to the non irradiated patients EW fell ill with CHD on 9.4 years earlier. Using proportional hazards analysis (Cox regression), it was found that EW had 3.9 times higher risk of CHD than in non irradiated individuals. Smoking and overweight brought three times less but significant risk - 1.37 and 1.33 respectively. The TT genotype unlike genotypes CC and CT gene PDE4D increased risk of MI in 1.757 times more both in EW and control group. The risk of CHD development was

    Higher mortality rates are reported because of cardiovascular diseases in individuals living in industrialized areas of the World. In cancer patients, cardiotoxic chemotherapeutic agents and/or mediastinal radiotherapy are additional risk factors for the development of coronary artery disease. An improved survival rate for patients with Hodgkin lymphoma was reported in recent decades. Determining and handling the long-term effects of cancer treatment have become more important nowadays, parallel to the good results reached in survival rates. Mediastinal radiotherapy and cardiotoxic chemotherapeutic agents are routinely used to treat Hodgkin lymphoma but are commonly associated with a variety of cardiovascular complications. Drugs used in cancer treatment and radiotherapy may cause deleterious effects on contractile capacity and conduction system of the heart. Approximately ten years after the completion of all therapies, the cardiovascular disease risk peaks in patients who survived from Hodgkin lymphoma. The value of coronary computed tomography angiography as a diagnostic tool in determining coronary artery disease as early as possible is underlined in this review, in patients who are in remission and carry the risk of coronary artery disease probably because of chemo/radiotherapy used in their treatment. Survivors of Hodgkin lymphoma especially treated with combined chemoradiotherapy at younger ages are candidates for coronary computed tomography angiography.

    Full Text Available Background: This article was to present the sampling and measurements methods and the main preliminary findings of the KERCADR cohort study (first round in an urban and peri-urban setting, Kerman, southeastern Iran2009-11. Method: 5900 (3238 female people aged between 15 to 75 years were recruited in the household survey by non-proportional to size one-stage cluster sampling. Trained internal specialists, general practitioners, clinical psychologists and dentists have assessed the study subjects by person-assisted questionnaires regarding different NCD risk factors including cigarette and opium smoking, physical activity, nutrition habits, anxiety, depression, obesity, hypertension and oral health. Blood samples were also collected for determining FBS, HbA1c, cholesterol and triglyceride. Weighted standardized prevalence estimates were calculated by STATA 10 survey analysis package. Results: The participation rate was more than 95% in all subgroups. Cigarette smoking (18.4% vs. 1.2%, opium use (17.8% vs. 3.0% and triglyceridemia (16.1% vs. 12.0% were significantly higher among men than women. In contrast, women were presented with higher level of sever anxiety (29.1% vs. 16.7%, obesity (16.8% vs. 9.2%, low-physical activity (45.1% vs. 39.2% and uncontrolled diabetes (60.2% vs. 31.0%. More than 68% of all subjects have presented with moderate to severe gingival index scores. Conclusion: The first round of the KERCADR cohort with sufficient sample size and response rate provided precise estimates for the main clinical and para-clinical NCD risk factors. These evidences need to be translated into public health interventions and monitored in the next rounds of the cohort.

    The purpose of this 12 month randomized exercise intervention was to determine the effect of a block-periodized multipurpose exercise program on bone mineral density (BMD) and parameters of the metabolic syndrome (MetS) in early post-menopausal women. Eighty-five subjects (52.3 ± 2.4 years) living in the area of Erlangen (Germany) were randomly assigned into an exercise (EG, n=43) or a wellness-control group (CG: n=42). The EG performed a periodized multipurpose exercise program with 4-6-week blocks of high-intensity bone-specific exercise intermitted by 10-12 weeks of exercise dedicated to increase endurance and reduce cardiac and metabolic risk factors. The CG performed a low-volume/low-intensity "wellness" program to increase well-being. After 12 months, significant exercise effects were observed for the lumbar spine (LS) BMD as assessed by quantitative computed tomography [total BMD (EG: -0.3 ± 2.1% vs CG: -2.1 ± 2.2%, P=0.015); trabecular BMD (EG: -0.7 ± 3.4% vs CG: -4.7 ± 4.9%, P=0.001) and dual-energy x-ray absorptiometry (DXA) (EG: -0.1 ± 2.2% vs CG: -2.0 ± 2.0%, P=0.002)]. However, no significant effects were observed for total hip BMD as assessed by DXA (P=0.152). Although all MetS parameters were favorably affected among the EG, only the effect for waist circumference was significant. In summary, short periods of bone-specific intervention embedded in longer periods of exercises dedicated to improve cardiovascular and metabolic risk factors positively affected BMD at the LS.

    Background Major Depressive Disorder (MDD) is one of the most common mental illnesses in psychiatry, being considered a risk factor for Acute Coronary Syndrome (ACS). Objective To assess the prevalence of MDD in ACS patients, as well as to analyze associated factors through the interdependence of sociodemographic, lifestyle and clinical variables. Methods Observational, descriptive, cross-sectional, case-series study conducted on patients hospitalized consecutively at the coronary units of three public hospitals in the city of Rio de Janeiro over a 24-month period. All participants answered a standardized questionnaire requesting sociodemographic, lifestyle and clinical data, as well as a structured diagnostic interview for the DSM-IV regarding ongoing major depressive episodes. A general log-linear model of multivariate analysis was employed to assess association and interdependence with a significance level of 5%. Results Analysis of 356 patients (229 men), with an average and median age of 60 years (SD ± 11.42, 27-89). We found an MDD point prevalence of 23%, and a significant association between MDD and gender, marital status, sedentary lifestyle, Killip classification, and MDD history. Controlling for gender, we found a statistically significant association between MDD and gender, age ≤ 60 years, sedentary lifestyle and MDD history. The log-linear model identified the variables MDD history, gender, sedentary lifestyle, and age ≤ 60 years as having the greatest association with MDD. Conclusion Distinct approaches are required to diagnose and treat MDD in young women with ACS, history of MDD, sedentary lifestyle, and who are not in stable relationships. PMID:28443957

    Full Text Available Coronary artery ectasia (CAE is characterized by inappropriate dilatation of the coronary vasculature. The mechanisms of CAE are not well known. Insulin-like growth factor-1 (IGF-1 may make endothelial cells and smooth muscle cells more sensitive to the effects of growth hormone. In the present study, we hypothesized that IGF-1 may have an impact on the formation of ectasia and aneurysm in arterial system, and aimed to investigate the associations between the presence of CAE and serum IGF-1 levels in patients undergoing coronary angiography. The study included 2.980 subjects undergoing elective diagnostic coronary angiography. We selected 40 patients diagnosed with CAE as CAE group and 44 subjects with absolutely normal coronary arteries were assigned as normal control group. IGF-1 levels were measured in both groups of patients. Groups were similar in terms of age, sex and coronary artery disease risk factors. The serum IGF-1 levels were significantly higher in CAE patients with 109.64±54.64 ng/mL than in controls with 84.76±34.01 ng/mL (p=0.016. HDL levels were lower in ectasia group with 41.5±10.7 mg/dL than controls with 47.7±10.4 mg/dL (p=0.018. By means of logistic regression analysis, high IGF-1 and low HDL levels were found to be independent risk factors for the presence of CAE (p<0.02, p<0.016, respectively. The study revealed that there was a positive correlation between serum IGF-1 levels and presence of CAE, and high IGF-1 levels and low HDL levels were independent risk factors for the presence of CAE. Future studies are needed to confirm these results.

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

    Today's definition of coronary artery disease (CAD) comprises two forms: obstructive and non-obstructive CAD. The 31-72% chance of a life-threatening event-like a myocardial infarction-with non-obstructive CAD is well documented in numerous studies. The objective in modern strategies of diagnosis and therapy should therefore be expedient identification of patients at high risk for coronary events, who will benefit from a customized therapy. Before initiating diagnostic procedures of CAD, a well defined strategy should be pursued. There are two possible primary objectives: ASSESSMENT OF THE INDIVIDUAL RISK FOR A CORONARY EVENT: Assessment of the individual "absolute" risk for a coronary event is not possible using single traditional risk factors. The individual risk can be estimated by integrating several of the traditional risk factors into a scoring system. These so-called risk scores (e.g. Framingham score and Procam score), however, have been associated with shortcomings: insufficient discrimination of high-risk from low-risk individuals. The calcium score has therefore become increasingly established; this Agatston score is independent of the traditional risk factors, so there is no correlation between Agatston and Procam scores. Today, the calcium score is considered the superior test for identifying individuals at high risk for a coronary event and its use is recommended by the European Society of Cardiology (ESC) guidelines for prevention of cardiovascular diseases. PROOF OR EXCLUSION OF A HEMODYNAMICALLY SIGNIFICANT CORONARY STENOSIS: Another concept is the definitive proof or exclusion of a hemodynamically "significant" coronary narrowing. The probability of an obstructive CAD is traditionally assessed by the type of chest pain, age, gender and stress-ECG. In patients with a low probability of an obstructive CAD, cardiac catheterization is not indicated, whereas in patients with a high probability of a hemodynamically significant coronary stenosis, an

    Evidence that alcohol consumption is inversely associated with long-term coronary artery disease (CAD) mortality independent of genetic and early life environmental factors is lacking. We evaluated whether alcohol consumption was prospectively associated with CAD mortality risk independent of familial factors. In total, 843 male twins (396 pairs and 51 unpaired twins) aged 42-55 y (mean: 48 y) without baseline CAD reported beer, wine, and spirits consumption at baseline (1969-1973) and were followed up to 2010 in the prospective National Heart, Lung, and Blood Institute Twin Study. Data on usual alcohol consumption over the past year were collected. Outcome was time to event, where the primary event was death from CAD and secondary events were death from cardiovascular disease and all causes. HRs were estimated by using frailty survival models, both overall and within-pair. There were 129 CAD deaths and 219 cardiovascular deaths during 41 y of follow-up. In the whole cohort, after adjustment for caloric intake and cardiovascular disease risk factors, overall HRs per 10-g increment in alcohol intake were 0.94 (95% CI: 0.89, 0.98) for CAD and 0.97 (95% CI: 0.93, 1.00) for cardiovascular mortality. The within-pair adjusted HRs for a twin with 10-g higher daily alcohol consumption than his co-twin were 0.90 (95% CI: 0.84, 0.97) for CAD and 0.95 (95% CI: 0.90, 1.00) for cardiovascular disease mortality in the cohort pooled by zygosity, which remained similar among monozygotic twins. All 3 beverage types tended to be associated with lower CAD mortality risk within-pair to a similar degree. Alcohol consumption was not associated with total mortality risk overall or within-pair. Higher usual alcohol consumption is associated with lower CAD mortality risk, independent of germline and early life environment and adulthood experience shared among twins, supporting a possible causal role of alcohol consumption in lowering CAD death risk.

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

    A family history of coronary artery disease (CAD) is an important risk factor for adverse coronary events, in particular if the disease has an early onset. The risk of CAD is influenced by genetic and environmental factors with a greater genetic contribution earlier in life. Through recent years...... Registry and risk factor control was evaluated. The study revealed that risk factors are common in early-onset CAD and that a large room for risk factor improvement remains. In study II, we used coronary computed tomography angiography to compare the coronary plaque burden and characteristics between 88...... first-degree relatives of patients with early-onset CAD and 88 controls with no familial predisposition. Relatives had a significantly increased coronary plaque burden, which displayed characteristics associated with myocardial ischemia and adverse coronary events. In study III, 134 patients with early...

    Objective: To explore the risk factors and clinical manifestation of coronary lesions in patients with premature coronary heart disease (PCHD), and to prior intervention and optimize therapeutic. Methods: A retrospective analysis of 373 cases of coronary artery disease patients underwent coronary angiography confirmed, 188 patients with PCAD and 185 patients with late CHD (LCHD) were divided by age. The relationship among the risk factors including body mass index (BMI), history of hypertension, diabetes, hyper-lipemia, smoking, alcohol consumption, premature family history of cardiovascular disease, and level of lipidemia, glucose, uricemia, bilirubin and clinical features of coronary lesions in coronary features were analyzed. Results: Patients with PCHD had higher levels of BMI, triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-c) and LP(a) compared with the LCAD group (P<0.05). The PCAD group had lower rate of diabetes (P<0.05), and hypertension (P>0.05). The patients with PCHD had lesions in single coronary artery (P<0.05). Conclusion: Patients with PCHD had many clinical cardiovascular risk factors, including obesity, smoking, alcohol consumption, premature family history of cardiovascular disease, hyperlipemia is a major risk factor for PCHD, so early preventing can help reduce the incidence of PCHD. The patients with PCHD had more single vessel disease. These patients were given a reasonable stent and the optimized drugs, which can significantly improve the prognosis.%目的:分析早发冠心病患者临床危险因素及冠脉病变的特点,以便对其早期干预及优化治疗.方法:回顾性分析373例在我院行冠脉造影术确诊为冠心病的患者,按年龄分为早发冠心病组188例(男≤55岁,女≤ 65岁)和晚发冠心病组185例,对两组患者的体重指数(BMI)、高血压病史、糖尿病史、高血脂病史、吸烟史、饮酒史、早发心血管病家族史,血脂、血糖、尿

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