    Full Text Available Abstract Background The purpose of the Finnish Cardiovascular Study (FINCAVAS is to construct a risk profile – using genetic, haemodynamic and electrocardiographic (ECG markers – of individuals at high risk of cardiovascular diseases, events and deaths. Methods and design All patients scheduled for an exercise stress test at Tampere University Hospital and willing to participate have been and will be recruited between October 2001 and December 2007. The final number of participants is estimated to reach 5,000. Technically successful data on exercise tests using a bicycle ergometer have been collected of 2,212 patients (1,400 men and 812 women by the end of 2004. In addition to repeated measurement of heart rate and blood pressure, digital high-resolution ECG at 500 Hz is recorded continuously during the entire exercise test, including the resting and recovery phases. About 20% of the patients are examined with coronary angiography. Genetic variations known or suspected to alter cardiovascular function or pathophysiology are analysed to elucidate the effects and interactions of these candidate genes, exercise and commonly used cardiovascular medications. Discussion FINCAVAS compiles an extensive set of data on patient history, genetic variation, cardiovascular parameters, ECG markers as well as follow-up data on clinical events, hospitalisations and deaths. The data enables the development of new diagnostic and prognostic tools as well as assessments of the importance of existing markers.

    The treatment of craniopharyngiomas is associated with long-term morbidity. To assess the long-term functional outcome and mortality rates after treatment for craniopharyngiomas, we audited our data with special focus on cardiovascular, neurological and psychosocial morbidity. Between 1965 and 2002, 54 consecutive patients underwent surgery for craniopharyngiomas at the Leiden University Medical Centre (LUMC). Fifteen patients (25%) received additional postoperative radiation therapy. The median follow-up period was 10 years (range 1-37 years). Long-term cure rate was 82% and long-term recurrence rate 18%. Visual fields/visual acuity stabilized or improved in 74% of cases. The long-term prevalence rate of hypopituitarism was 89%. In addition, long-term cardiovascular, neurological and psychosocial morbidity rates were high: 22% (risk factors 57%), 49% and 47%, respectively. Female sex was an independent predictor of increased cardiovascular, neurological and psychosocial morbidity (odds ratio 3.78, P = 0.031). Ten patients (18%) died during an 828 person-year follow-up. The actuarial patient survival rates 5, 10 and 20 years after the initial operation were 95, 85 and 85%, respectively. The standardized mortality ratio (SMR) was 2.88 [95% confidence interval (CI) 1.35-4.99]. Craniopharyngioma is associated with excessive long-term multisystem morbidity and mortality, especially in female patients, despite a high cure rate. These observations indicate that dedicated long-term follow-up of these patients is required. The purpose of the follow-up should be: first, to look for recurrences and to ensure appropriate endocrine replacement, especially oestrogen replacement in premenopausal females; and second, to achieve intensive control of glucose, lipids, blood pressure and weight, as in any other patient with increased risk for cardiovascular disease.

    Recent progress in population health at aggregate level, measured by life expectancy, has been accompanied by lack of progress in reducing the difference in health prospects between groups defined by social status. Cardiovascular disease is an important contributor to this undesirable situation. The stepwise gradient of higher risk with lower status is accounted for partly by social gradients in health behaviors. The psychosocial hypothesis provides a stronger explanation, based on social patterning of living and working environments and psychological assets that individuals develop during childhood. Three decades of research based on Whitehall II and other cohort studies provide evidence for psychosocial pathways leading to cardiovascular morbidity and mortality. Job stress is a useful paradigm because exposure is long term and depends on occupational status. Studies of social-biological translation implicate autonomic and neuroendocrine function among the biological systems that mediate between chronic adverse psychosocial exposures and increased cardiometabolic risk and cardiovascular disease incidence.

    Cardiovascular diseases (CVDs) are now in a rising trend in South East Asia including Myanmar due to increase in major cardiovascular risk factors in both urban and rural areas, such as smoking, obesity and diabetes mellitus. It is necessary to determine CVD morbidities in Myanmar for planning of prevention and control activities for CVDs. The cross-sectional household survey was conducted in 2012 with 600 people aged 40 years and above in four townships (Kyauk-Tan, Mawlamyaing, Pathein and Pyay) and used face-to-face interview with standard questionnaire [Rose Angina Questionnaire and Questionnaire by European Cardiovascular Indicators Surveillance Set (EUROCISS) Research Group] to determine the level of reported CVD morbidities in adult population. Age of the study population ranged from 40 to 99 years with the mean age of 56 years. Seventy-one percent of the study population was women. Nine percent of the study population have suffered from angina according to Rose Angina Questionnaire. Prevalence of possible heart attack, stroke and heart failure was 7.5, 1.5 and 2.8%. Prevalence of hypertension was 51%. The CVD morbidities are high. There is a need for strengthening prevention and control activities of CVDs.

    Kidney transplantation is the optimal treatment for patients with end stage renal disease (ESRD) who would otherwise require dialysis. Patients with ESRD are at dramatically increased cardiovascular (CV) risk compared to the general population. As well as improving quality of life, successful transplantation accords major benefits by reducing cardiovascular risk in these patients. Worldwide, cardiovascular disease remains the leading cause of death with a functioning graft and therefore is a ...

    Background Morbid obesity is directly related to deterioration in cardiorespiratory capacity, including changes in cardiovascular autonomic modulation. Objective This study aimed to assess the cardiovascular autonomic function in morbidly obese individuals. Methods Cross-sectional study, including two groups of participants: Group I, composed by 50 morbidly obese subjects, and Group II, composed by 30 nonobese subjects. The autonomic function was assessed by heart rate variability in the time domain (standard deviation of all normal RR intervals [SDNN]; standard deviation of the normal R-R intervals [SDNN]; square root of the mean squared differences of successive R-R intervals [RMSSD]; and the percentage of interval differences of successive R-R intervals greater than 50 milliseconds [pNN50] than the adjacent interval), and in the frequency domain (high frequency [HF]; low frequency [LF]: integration of power spectral density function in high frequency and low frequency ranges respectively). Between-group comparisons were performed by the Student’s t-test, with a level of significance of 5%. Results Obese subjects had lower values of SDNN (40.0 ± 18.0 ms vs. 70.0 ± 27.8 ms; p = 0.0004), RMSSD (23.7 ± 13.0 ms vs. 40.3 ± 22.4 ms; p = 0.0030), pNN50 (14.8 ± 10.4 % vs. 25.9 ± 7.2%; p = 0.0061) and HF (30.0 ± 17.5 Hz vs. 51.7 ± 25.5 Hz; p = 0.0023) than controls. Mean LF/HF ratio was higher in Group I (5.0 ± 2.8 vs. 1.0 ± 0.9; p = 0.0189), indicating changes in the sympathovagal balance. No statistical difference in LF was observed between Group I and Group II (50.1 ± 30.2 Hz vs. 40.9 ± 23.9 Hz; p = 0.9013). Conclusion morbidly obese individuals have increased sympathetic activity and reduced parasympathetic activity, featuring cardiovascular autonomic dysfunction. PMID:26536979

    Full Text Available Cardiovascular (CVS morbidity and mortality in the endstage renal disease (ESRD patients on peritoneal dialysis therapy is 10-30 folds higher than in general population. The prevalence of well known traditional risk factors such as age, sex, race, arterial hypertension, hyperlipidaemia, diabetes, smoking, physical inactivity is higher in the uraemic patients. Besides these, there are specific, nontraditional risk factors for dialysis patients. Mild inflammation present in peritoneal dialysis (PD patients which can be confirmed by specific inflammatory markers is the cause of CVS morbidity and mortality in these patients. Hypoalbuminaemia, hyperhomocysteinaemia and a higher level of leptin are important predictors of vascular complications as well as CVS events in the PD patients. Plasma norepinephrine, an indicator of sympathetic activity, is high in the ESRD patients and higher in the PD patients than in the patients on haemodialysis (HD. Therefore, norepinephrine may be a stronger risk factor in the PD patients. The same applies to asymmetric dimethylargine (ADMA, an endogenous inhibitor of nitric oxide synthase, which is an important risk factor of CVS morbidity and mortality 15 % higher in the PD than the HD patients. Hyperphosphataemia, secondary hyperparathyroidism and high calcium x phosphate product have been associated with the progression of the coronary artery calcification and valvular calcifications and predict all-cause CVS mortality in the PD patients. Residual renal function (RRF declines with time on dialysis but is slower in the PD than the HD patients. RRF decline is associated with the rise of proinflammatory cytokines and the onset of hypervolaemia and hypertension which increase the risk of CVS diseases, mortality in general and CVS mortality. In conclusion, it is very important to establish all CVS risk factors in the PD patients to prevent CVS diseases and CVS mortality in this population.

    Klotho gene was identified as an aging suppressor. In animals klotho over-expression extends lifespan and defective klotho results in rapid aging and early death. The kidney is the main contributor to circulating klotho levels and during chronic kidney disease, renal klotho gene expression is drastically reduced in animals and humans as well. We aimed to determine the consequences of a serum klotho defect on cardiovascular morbidity and mortality during chronic dialysis. The ARNOGENE study was designed to prospectively follow a cohort of hemodialysis patients for 2 years without specific intervention. 769 patients were recruited and followed from the end of 2008 until January 2011. 238 patients were analysed due to a technical sample conservation issue with other samples. The median serum klotho was markedly reduced, 360.4 ng/L [IQR176.5] as compared with non-dialysis chronic kidney disease patients or healthy volunteers. Patients with a serum klotho above the first quartile (≥280 ng/L) had a significantly reduced occurrence of outcome combining cardiovascular events and cardiovascular death (OR=0.39; 0.19-0.78, p=0.008) compared to patient with klotho <280 ng/L. This effect persisted (OR=0.86; 0.76-0.99, p=0.03) after adjustment on age, gender, diabetes, cardiac insufficiency, dialysis vintage, and serum hemoglobin, albumin, FGF-23, phosphate and calcium. These results suggest that during chronic hemodialysis, conservation of serum klotho above 280 ng/L is associated with a better 2-yr cardiovascular protection. Thus, a preserved klotho function supports cardiovascular protection and may represent a prognostic tool and therapeutic target for cardiovascular disease.

    Elevated mortality associated with high ambient temperatures in summer represents one of the main impacts of weather extremes on human society. Increases in cardiovascular mortality during heat waves have been reported in many European countries; much less is known about which particular cardiovascular disorders are most affected during heat waves, and whether similar patterns are found for morbidity (hospital admissions). Relatively less understood is also cold-related mortality and morbidity in winter, when the relationships between weather and human health are more complex, less direct, and confounded by other factors such as epidemics of influenza/acute respiratory infections. The present study analyses relationships between temperature extremes and cardiovascular morbidity and mortality. We make use of the datasets on hospital admissions and daily mortality in the population of the Czech Republic (about 10.3 million) over 1994-2009. The data have been standardized to remove the effects of the long-term trend and the seasonal and weekly cycles. Periods when the morbidity/mortality data were affected by epidemics of influenza and other acute respiratory infections have been removed from the analysis. We use analogous definitions for hot and cold spells based on quantiles of daily average temperature anomalies, which allows for a comparison of the findings for summer hot spells and winter cold spells. The main aims of the study are (i) to identify deviations of mortality and morbidity from the baseline associated with hot and cold spells, (ii) to compare the hot- and cold-spell effects for individual cardiovascular diseases (e.g. ischaemic heart disease I20-I25, cerebrovascular disease I60-I69, hypertension I10, aterosclerosis I70) and to identify those diagnoses that are most closely linked to temperature extremes, (iii) to identify population groups most vulnerable to temperature extremes, and (iv) to compare the links to temperature extremes for morbidity and

    Full Text Available The objective was to evaluate the hypothesis that growth-differentiation factor 15 (GDF-15 is an independent marker of the long-term risk for both cardiovascular disease and cancer morbidity beyond clinical and biochemical risk factors. Plasma obtained at age 71 was available from 940 subjects in the Uppsala Longitudinal Study of Adult Men (ULSAM cohort. Complete mortality and morbidity data were obtained from public registries. At baseline there were independent associations between GDF-15 and current smoking, diabetes mellitus, biomarkers of cardiac (high-sensitivity troponin-T, NT-proBNP and renal dysfunction (cystatin-C and inflammatory activity (C-reactive protein, and previous cardiovascular disease (CVD. During 10 years follow-up there occurred 265 and 131 deaths, 115 and 46 cardiovascular deaths, and 185 and 86 events with coronary heart disease mortality or morbidity in the respective total cohort (n=940 and non-CVD (n=561 cohort. After adjustment for conventional cardiovascular risk factors, one SD increase in log GDF-15 were, in the respective total and non-CVD populations, associated with 48% (95%CI 26 to 73%, p<0.001 and 67% (95%CI 28 to 217%, p<0.001 incremental risk of cardiovascular mortality, 48% (95%CI 33 to 67%, p<0.001 and 61% (95%CI 38 to 89%, p<0.001 of total mortality and 36% (95%CI 19 to 56%, p<0.001 and 44% (95%CI 17 to 76%, p<0.001 of coronary heart disease morbidity and mortality. The corresponding incremental increase for cancer mortality in the respective total and non-cancer disease (n=882 population was 46% (95%CI 21 to 77%, p<0.001 and 38% (95%CI 12 to 70%, p<0.001 and for cancer morbidity and mortality in patients without previous cancer disease 30% (95%CI 12 to 51%, p<0.001. In conclusion, in elderly men, GDF-15 improves prognostication of both cardiovascular, cancer mortality and morbidity beyond established risk factors and biomarkers of cardiac, renal dysfunction and inflammation.

    2014-07-01

    Full Text Available The pathogenesis of cardiovascular disease in CKD differs subtly from that of non-CKD patients. As renal function declines, the role and impact of treating classical risk factors may change and diminish. However, hypertension, hypercholesterolaemia and smoking cessation management should be optimized and may require multiple agents and approaches, particularly as CKD advances. Hypertension treatment would appear to be one management area in which performance is less than ideal. Moreover there are mechanisms and risk factors that are specific to CKD, capable of triggering a vascular pathology and that justify the surplus of CV morbidity in CKD patients and that require we consider CKD as a CV risk factor per se. In the initial stages of CKD it would be advisable to implement all the preventative measures to stem the onset of CV disease, whereas in the more advanced stages a multifactorial approach is likely to be necessary, as we have learned from the STENO-study within the diabetes.

    Full Text Available Background/Aim. Cardiovascular diseases are the leading cause of death in patients treated with hemodialysis (HD. The annual cardiovascular mortality rate in these patients is 9%. Left ventricular (LV hypertrophy, ischemic heart disease and heart failure are the most prevalent cardiovascular causes of death. The aim of this study was to assess the prevalence of traditional and nontraditional risk factors for cardiovascular complications, to assess the prevalence of cardiovascular complications and overall and cardiovascular mortality rate in patients on HD. Methods. We investigated a total of 115 patients undergoing HD for at least 6 months. First, a cross-sectional study was performed, followed by a two-year follow-up study. Beside standard biochemical parameters, we also determined cardiac troponins and echocardiographic parameters of LV morphology and function (LV mass index, LV fractional shortening, LV ejection fraction. The results were analyzed using the Student's t test and Mann-Whitney U test. Results. The patients with adverse outcome had significantly lower serum albumin (p < 0.01 and higher serum homocystein, troponin I and T, and LV mass index (p < 0.01. Hyperhomocysteinemia, anemia, hypertriglyceridemia and uncontrolled hypertension had the highest prevalence (86.09%, 76.52%, 43.48% and 36.52%, respectively among all investigated cardiovascular risk factors. Hypertrophy of the LV was presented in 71.31% of the patients and congestive heart failure in 8.70%. Heart valve calcification was found in 48.70% of the patients, pericardial effusion in 25.22% and disrrhythmia in 20.87% of the investigated patients. The average annual overall mortality rate was 13.74%, while average cardiovascular mortality rate was 8.51%. Conclusion. Patients on HD have high risk for cardiovascular morbidity and mortality.

    Full Text Available BACKGROUND Chronic Obstructive Pulmonary Disease (COPD is the fourth largest cause of death worldwide. However, most patients with COPD die from cardiovascular causes (CVD. COPD is an independent risk factor for CVD and a predictor of long-term mortality. There is a high prevalence of traditional risk factors in this patient group, including smoking, sedentary behaviour and low socio-economic class. COPD is now recognized to having both local lung and systemic effects. The mechanism of such systemic effects is not completely known, but it is supposed to be related to enhanced systemic inflammation and to oxidative stress, both implicated in the pathogenesis of atherosclerotic process. CONCLUSIONS COPD is frequently associated with congestive heart failure (CHF. It is also a confounding factor for the diagnosis of CHF. In fact, some studies demonstrate that about 20% of patients diagnosed with COPD had also or only CHF. Patients with CHF and associated COPD have less frequently β-blockers prescription than CHF patients without COPD. COPD is a heavy negative prognostic factor for CHF hospitalization and mortality. Pulmonary Embolism (PE in patients with COPD is generally underdiagnosed, and this last disease is a risk factor for a complicated course of PE, with increased mortality.

    Full Text Available Christine Macie, Kate Wooldrage, Jure Manfreda, Nicholas AnthonisenDepartment of Medicine, University of Manitoba, Winnipeg, Manitoba, CanadaAbstract: We used the Manitoba Health database to examine the relationship between use of inhaled respiratory drugs in people with chronic obstructive respiratory diseases and cardiovascular hospitalizations from 1996 through 2000. The drugs examined were beta agonists [BA], ipratropium bromide IB, and inhaled steroids (ICS. End points were first hospitalizations for supraventricular tachycardia, myocardial infarction, heart failure or stroke. A nested case control analysis was employed comparing people with and without cardiovascular events. Cases and controls were matched for gender and age, and conditional logistic regression was used in multivariate analysis considering other respiratory drugs, respiratory diagnosis and visit frequency, non-respiratory, non-cardiac comorbidities, and receipt of drugs for cardiovascular disease. In univariate analyses, BA, IB and ICS were all associated with hospitalizations for cardiovascular disease, but in multivariate analyses ICS did not increase risk while both BA and IB did. There were interactions between respiratory and cardiac drugs receipt in that bronchodilator associated risks were higher in people not taking cardiac drugs; this was especially true for stroke. There were strong interactions with specific cardiac drugs; for example, both BA and IB substantially increased the risk of supraventricular tachycardia in patients not anti-arryhthmic agents, but not in the presence of such agents. We conclude that bronchodilator therapy for chronic obstructive diseases is associated with increased cardiovascular risk, especially in patients without previous cardiovascular diagnoses, and that this is unlikely due to the severity of the respiratory disease, since risk was not increased with ICS.Keywords: bronchodilator therapy, inhaled corticosteroids, nested case

    2014-03-01

    Full Text Available The epidemiologic evidence linking COPD and cardiovascular morbidity and mortality is strong. Even after adjustments for traditional cardiovascular risk factors such as serum total cholesterol hypertension, obesity and smoking, patients with COPD have a two- to threefold increase in the risk of cardiovascular events including death. Age >60 yrs., Male sex, Significant Smoking History, T2 Diabetes Mellitus, Body Mass Index >30 Kg/M2, Left Ventricular Hypertrophy have a statistically significant correlation to cardiovascular mortality & morbidity. Significant relations were demonstrated between the treatment that patient requires for stability & cardiovascular morbidity & mortality in Central India.

  5. Heat- and cold-stress effects on cardiovascular mortality and morbidity among urban and rural populations in the Czech Republic

    2014-08-01

    Several studies have examined the relationship of high and low air temperatures to cardiovascular mortality in the Czech Republic. Much less is understood about heat-/cold-related cardiovascular morbidity and possible regional differences. This paper compares the effects of warm and cold days on excess mortality and morbidity for cardiovascular diseases (CVDs) in the city of Prague and a rural region of southern Bohemia during 1994-2009. Population size and age structure are similar in the two regions. The results are evaluated for selected population groups (men and women). Excess mortality (number of deaths) and morbidity (number of hospital admissions) were determined as differences between observed and expected daily values, the latter being adjusted for long-term changes, annual and weekly cycles, and epidemics of influenza/acute respiratory infections. Generally higher relative excess CVD mortality on warm days than on cold days was identified in both regions. In contrast to mortality, weak excess CVD morbidity was observed for both warm and cold days. Different responses of individual CVDs to heat versus cold stress may be caused by the different nature of each CVD and different physiological processes induced by heat or cold stress. The slight differences between Prague and southern Bohemia in response to heat versus cold stress suggest the possible influence of environmental and socioeconomic factors such as the effects of urban heat island and exposure to air pollution, lifestyle differences, and divergence in population structure, which may result in differing vulnerability of urban versus rural population to temperature extremes.

    Sairam Parthasarathy

    Full Text Available BACKGROUND: Nocturia has been independently associated with cardiovascular morbidity and all-cause mortality, but such studies did not adjust for sleep-disordered breathing (SDB, which may have mediated such a relationship. Our aims were to determine whether an association between nocturia and cardiovascular morbidity exists that is independent of SDB. We also determined whether nocturia is independently associated with SDB. METHODOLOGY/PRINCIPAL FINDINGS: In order to accomplish these aims we performed a cross-sectional analysis of the Sleep Heart Health Study that contained information regarding SDB, nocturia, and cardiovascular morbidity in a middle-age to elderly community-based population. In 6342 participants (age 63±11 [SD] years, 53% women, after adjusting for known confounders such as age, body mass index, diuretic use, diabetes mellitus, alpha-blocker use, nocturia was independently associated with SDB (measured as Apnea Hypopnea index >15 per hour; OR 1.3; 95%CI, 1.2-1.5. After adjusting for SDB and other known confounders, nocturia was independently associated with prevalent hypertension (OR 1.23; 95%CI 1.08-1.40; P = 0.002, cardiovascular disease (OR 1.26; 95%CI 1.05-1.52; P = 0.02 and stroke (OR 1.62; 95%CI 1.14-2.30; P = 0.007. Moreover, nocturia was also associated with adverse objective alterations of sleep as measured by polysomnography and self-reported excessive daytime sleepiness (P<0.05. CONCLUSIONS/SIGNIFICANCE: Nocturia is independently associated with sleep-disordered breathing. After adjusting for SDB, there remained an association between nocturia and cardiovascular morbidity. Such results support screening for SDB in patients with nocturia, but the mechanisms underlying the relationship between nocturia and cardiovascular morbidity requires further study. MeSH terms: Nocturia, sleep-disordered breathing, obstructive sleep apnea, sleep apnea, polysomnography, hypertension.

    We investigated the association between high parity and fetal morbidity outcomes. We analyzed 22,463,141 singleton deliveries at 20 weeks or more of gestation in the United States from 1989 through 2000. Adjusted odds ratios generated from logistic regression models were used to approximate relative risk for neonatal morbidity in women with 1-4 (moderate parity or type I; referent group), 5-9 (high parity or type II), 10-14 (very high parity or type III) and 15 or more (extremely high parity or type IV) prior live births. Main outcome measures included low and very low birth weight, preterm and very preterm birth, and small and large for gestational age delivery. The overall crude rates for low birth weight, very low birth weight, preterm birth, very preterm birth, and small and large for gestational age were 55, 11, 97, 19, 83, and 129 per 1,000 live births, respectively. The adjusted odds ratios for low birth weight, very low birth weight, preterm, and very preterm delivery increased consistently and in a dose-effect fashion with ascending parity (P for trend < .001). In the case of large for gestational age delivery, the adjusted odds ratio showed an inverted-U pattern, being highest among women in the type III parity cluster. The findings with respect to small for gestational age were inconclusive. High parity is a risk factor for adverse fetal outcomes. However, the impact of heightened parity is more manifest as shortened gestation rather than physical size restriction. These findings could prove beneficial for counseling women of high parity.

    2016-09-27

    Epidemiological evidence is accumulating that indicates greater time spent in sedentary behavior is associated with all-cause and cardiovascular morbidity and mortality in adults such that some countries have disseminated broad guidelines that recommend minimizing sedentary behaviors. Research examining the possible deleterious consequences of excess sedentary behavior is rapidly evolving, with the epidemiology-based literature ahead of potential biological mechanisms that might explain the observed associations. This American Heart Association science advisory reviews the current evidence on sedentary behavior in terms of assessment methods, population prevalence, determinants, associations with cardiovascular disease incidence and mortality, potential underlying mechanisms, and interventions. Recommendations for future research on this emerging cardiovascular health topic are included. Further evidence is required to better inform public health interventions and future quantitative guidelines on sedentary behavior and cardiovascular health outcomes.

    We examined the association of cardiovascular health at younger ages with the proportion of life lived free of morbidity, the cumulative burden of morbidity, and average healthcare costs at older ages. The CHA study (Chicago Heart Association Detection Project in Industry) is a longitudinal cohort of employed men and women 18 to 74 years of age at baseline examination in 1967 to 1973. Baseline measurements included blood pressure, cholesterol, diabetes mellitus, body mass index, and smoking. Individuals were classified into 1 of 4 strata of cardiovascular health: favorable levels of all factors, 0 factors high but ≥1 elevated risk factors, 1 high risk factor, and ≥2 high risk factors. Linked Medicare and National Death Index data from 1984 to 2010 were used to determine morbidity in older age. An individual's all-cause morbidity score and cardiovascular morbidity score were calculated from International Classification of Disease, Ninth Revision codes for each year of follow-up. We included 25 804 participants who became ≥65 years of age by 2010, representing 65% of all original CHA participants (43% female; 90% white; mean age, 44 years at baseline); 6% had favorable levels of all factors, 19% had ≥1 risk factors at elevated levels, 40% had 1 high risk factor, and 35% had ≥2 high risk factors. Favorable cardiovascular health at younger ages extended survival by almost 4 years and postponed the onset of all-cause and cardiovascular morbidity by 4.5 and 7 years, respectively, resulting in compression of morbidity in both absolute and relative terms. This translated to lower cumulative and annual healthcare costs for those in favorable cardiovascular health (P<0.001) during Medicare eligibility. Individuals in favorable cardiovascular health in early middle age live a longer, healthier life free of all types of morbidity. These findings provide strong support for prevention efforts earlier in life aimed at preserving cardiovascular health and reducing the

  13. Body water distribution and risk of cardiovascular morbidity and mortality in a healthy population: a prospective cohort study.

    Directory of Open Access Journals (Sweden)

    Nikoline Nygård Knudsen

    Full Text Available BACKGROUND: Early alterations in the cardiovascular structure and function may change normal body water distribution. The resulting fluid shifts may thus serve as an early marker for cardiovascular disease. However, studies examining this in healthy populations are absent. OBJECTIVE: This study examined the association between the proportion of total body water that is extracellular water and subsequent development of non-fatal or fatal cardiovascular disease in a healthy population. METHOD: Bioelectrical impedance spectroscopy is an easy-to-use, non-invasive and relatively inexpensive technique to evaluate changes in body water distribution. A random subset (n = 2120 of Danes aged 41-71 years, examined in 1993-1994 for body water distribution by bioelectrical impedance spectroscopy was included. Cox-proportional hazard models and linear splines were performed. The ratio between resistance estimates from an infinite-frequency and from no-frequency (R∞/R0 was used as a surrogate measure of ratio between extracellular water and total body water. The outcome was 13.5 years of follow-up for cardiovascular morbidity and mortality. RESULTS: A high proportion of total body water that is extracellular water was associated with increased risk of incident cardiovascular disease. A threshold effect was evident, with greatly increased risk of cardiovascular morbidity and mortality above R∞/R0 = 0.68. Below the threshold there seemed to be no additional benefit of having a low ratio. CONCLUSION: Our findings suggest that non-clinically evident oedema, measured as an increased proportion of total body water that is extracellular, above a threshold of 0.68, may be an early marker of pre-clinical cardiovascular disease. This simple, safe, cheap and easily obtainable measure of R∞/R0 from bioelectrical impedance may help the early identification of these otherwise clinically healthy individuals who are at an increased risk of future cardiovascular disease

    Full Text Available Cardiovascular diseases (CVDs are among the top health problems of the Chinese population. Although mounting evidence suggests that early childhood health status has an enduring effect on late life chronic morbidity, no study so far has analyzed the issue in China. Using nationally representative data from the 2013 China Health and Retirement Longitudinal Study (CHARLS, a Probit model and Two-Stage Residual Inclusion estimation estimator were applied to analyze the relationship between childhood health status and adulthood cardiovascular disease in rural China. Good childhood health was associated with reduced risk of adult CVDs. Given the long-term effects of childhood health on adulthood health later on, health policy and programs to improve the health status and well-being of Chinese populations over the entire life cycle, especially in persons’ early life, are expected to be effective and successful.

  15. Impaired Neurovisceral Integration of Cardiovascular Modulation Contributes to Multiple Sclerosis Morbidities.

    2017-01-01

    Multiple sclerosis (MS) is an inflammatory demyelinating central nervous system (CNS) disease with an uncertain etiology. MS is heterogeneous, involving multiple clinical pathologies, including neurodegeneration, depression, fatigue and sleep disorders, migraine, osteoporosis and cerebral hemodynamic impairments. The underlying causes of these pathologies remain mostly unknown. Based on the accumulating evidence derived from our studies and those of other investigators, we propose that the dysregulation in the neurovisceral integration of cardiovascular modulation can lead to many MS-related clinical symptoms. We show that MS inflammatory and neurodegenerative processes are intertwined with the aforementioned clinical morbidities and are collectively the manifestations of cardiovascular autonomic nervous system (ANS) dysfunction. The strategies for improving sympathovagal balance would likely prevent and minimize many MS-related clinical symptoms, improving patients' quality of life. Similar strategies could be applied to other autoimmune and neurodegenerative diseases where autonomic imbalance plays a role.

  16. Do sudden air temperature and pressure changes affect cardiovascular morbidity and mortality?

    Plavcová, E.; Davídkovová, H.; Kyselý, J.

    2012-04-01

    Previous studies have shown that sudden changes in weather (usually represented by air temperature and/or pressure) are associated with increases in daily mortality. Little is understood about physiological mechanisms responsible for the impacts of weather changes on mortality, and whether similar patterns appear for morbidity as well. Relatively little is known also about differences in the magnitude of the mortality response in provincial regions and in cities, where the impacts may be exacerbated by air pollution effects and/or heat island. The present study examines the effects of sudden air temperature and pressure changes on morbidity (represented by hospital admissions) and mortality due to cardiovascular diseases in the population of the Czech Republic (approx. 10 million inhabitants) and separately in the city of Prague (1.2 million inhabitants). The events are selected from data covering 1994-2009 using the methodology introduced by Plavcová and Kyselý (2010), and they are compared with the datasets on hospital admissions and daily mortality (both standardized to account for long-term changes and the seasonal and weekly cycles). Relative deviations of morbidity/mortality from the baseline were averaged over the selected events for days D-2 (2 days before a change) up to D+7 (7 days after), and their statistical significance was tested by means of the Monte Carlo method. The study aims at (i) identifying those weather changes associated with increased cardiovascular morbidity/mortality, separately in summer and winter, (ii) comparing the effects of weather changes on morbidity and mortality, (iii) identifying whether urban population of Prague is more/less vulnerable in comparison to the population of the whole Czech Republic, (iv) comparing the effects for different cardiovascular diseases (ischaemic heart diseases, ICD-10 codes I20-I25; cerebrovascular diseases, I60-I69; hypertension, I10; atherosclerosis, I70) and individual population groups (by age

    Golden, Jackelyn B.; McCormick, Thomas S.; Ward, Nicole L.

    2013-01-01

    Psoriasis is a prevalent, chronic inflammatory disease of the skin mediated by cross-talk occurring between epidermal keratinocytes, dermal vascular cells and immunocytes, including activated antigen presenting cells (APCs), monocytes/macrophages, and Th1 and Th17 cells. Increased proliferation of keratinocytes and endothelial cells in conjunction with immune cell infiltration leads to the distinct epidermal and vascular hyperplasia that is characteristic of lesional psoriatic skin. Interaction of activated T cells with monocytes/macrophages occurs via the Th17/IL-23 axis and is crucial for maintaining the chronic inflammation. Recent epidemiological evidence has demonstrated that psoriasis patients have an increased risk of developing and dying of cardiovascular disease. Similar pathology between psoriasis and cardiovascular disease, including involvement of key immunologic cell populations together with release of common inflammatory mediators such as IL-17A suggest a mechanistic link between the two diseases. This review will focus on concepts critical to psoriasis pathogenesis, systemic manifestations of psoriasis, the role of IL-17 in psoriasis and cardiovascular disease and the potential role for IL-17 in mediating cardiovascular co-morbidities in psoriasis patients.

    Zhilian Li

    Full Text Available Pulmonary hypertension (PH was recently recognized as a common complication of end-stage renal disease (ESRD that causes an increased risk of mortality. Epidemiological data for this disorder in earlier stages of chronic kidney disease (CKD and its association with cardiovascular (CV morbidity are scarce.We retrospectively analyzed 2,351 Chinese CKD patients with complete clinical records and echocardiography data between Jan 2008 and May 2012. The patients were divided into the following 6 groups: CKD Stages 1-4; Stage 5 for those not on or initiated on hemodialysis for <3 months; and Stage 5D for the patients undergoing hemodialysis for ≥3 months. The prevalence of PH and CV morbidity was investigated, and their association was evaluated with a logistic regression model.PH was detected in 426 patients (18.1%. Mild, moderate and severe PH was diagnosed in 12.1%, 4.9% and 1.1% of the patients, respectively. Severe PH was detected in CKD Stages 5 and 5D. CV morbidity was found in 645 patients (27.4%. Compared with the non-PH group, the PH group had a higher risk for cardiac disease but not for cerebrovascular disease risk. PH severity was associated with cardiac morbidity risk [odds ratio (95% CI for mild PH: 1.79 (1.30-2.47; moderate PH: 2.75 (1.73-4.37; severe PH: 3.90 (1.46-10.42].Our study showed for the first time the epidemiology profile of PH across the spectrum of CKD. Mild-to-moderate PH occurs with more frequency in advanced CKD, and severe PH is scarce in non-ESRD CKD. PH in CKD is associated with cardiac but not cerebrovascular disease, with increasing cardiac morbidity seen with increasing PH severity. Evidence from prospective studies addressing PH in this population is needed to predict cardiac events.

    Background and Objective: Complications following cardiovascular surgery incision are common in mediastinitis and wound dehiscence form, a 47% mortality rate remaining. Low Level Laser Therapy (LLLT) has been employed mainly to its effectiveness analgesic and anti-inflammatory actions, aiding the tissue repair process. The aim of this study was to evaluate infrared LLLT onto surgical incision in patients submitted to cardiovascular surgery. Materials and Methods: 40 patients were divided in two groups: Placebo Group (G1) - conventional therapy + "Laser pointer" and Laser Group (G2) - conventional therapy + Infrared Laser irradiation on surgical incision. Diode Laser was employed, C.W. mode, around the surgical wound bed, on immediate Post Operative (PO), 1st PO and 3rd PO with the following parameters: wavelength (λ): 830nm, P=35mW, E=0,75J. Results: G2 didn't present any complication and 5% of patients in G1 developed incision dehiscence and infection. On 7thPO, still a large amount of G1 patients showed pain and unquestionable inflammatory signs surrounding the surgical wound, when compared to G2. Besides, hospital stay in Laser Group was 2 times shorter than in Placebo Group (p-value=0.001). Conclusion: Infrared Laser denoted to be safe and exceptionally valuable tools in preventing morbidities on post cardiovascular surgeries.

    to assess how well insulin resistance predicts cardiovascular disease (CVD) in non-diabetic men and women and to explore the influence of physical activity. in this prospective study 2563 men and women without diabetes were examined with an oral glucose tolerance test, anthropometric measurements and blood pressure assessment. Questionnaires about lifestyle and physical activity were completed. Insulin resistance was estimated by fasting concentrations of plasma insulin and by HOMA index for insulin resistance. Participants were followed up for cardiovascular morbidity and mortality during an 8-year period, using information from the National Swedish Inpatient and Mortality registers. at follow-up, HOMAir predicted CVD morbidity in males (50 events) and females (28 events) combined (HRage/sex-adj 1.4, 95% CI 1.1-1.7); however, when stratified by gender HOMAir was predictive solely in men (HRage-adj 1.8, 95% CI 1.3-2.4), whereas no association was found in women (HRage-adj 1.1, 95% CI 0.8-1.5). When stratifying the data for high and low physical activity, the predictive value of insulin resistance became stronger in sedentary men (HRage-adj 2.3, 95% CI 1.5-3.4) but was abolished in men performing moderate to vigorous physical activity (HRage-adj 1.0, 95% CI 0.6-1.6). The results remained when step-wise adjusted also for BMI, ApoB/ApoA1 and hypertension, as well as for smoking, alcohol consumption and education. Outcome for fasting plasma insulin was similar to HOMAir. insulin resistance predicts CVD in the general population; however, men may be more vulnerable to increased insulin resistance than women, and physically inactive men seem to be at high risk. © The European Society of Cardiology 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Nonadherence to antihypertensive treatment is a common problem in cardiovascular prevention and may influence prognosis. We explored predictors of adherence to antihypertensive treatment and the association of adherence with acute cardiovascular events. Using data obtained from 400 Italian primary care physicians providing information to the Health Search/Thales Database, we selected 18,806 newly diagnosed hypertensive patients >or=35 years of age during the years 2000 to 2001. Subjects included were newly treated for hypertension and initially free of cardiovascular diseases. Patient adherence was subdivided a priori into 3 categories-high (proportion of days covered, >or=80%), intermediate (proportion of days covered, 40% to 79%), and low (proportion of days covered, low adherence levels, respectively. Multiple drug treatment (odds ratio, 1.62; 95% CI, 1.43 to 1.83), dyslipidemia (odds ratio, 1.52; 95% CI, 1.24 to 1.87), diabetes mellitus (odds ratio, 1.40; 95% CI, 1.15 to 1.71), obesity (odds ratio, 1.50; 95% CI, 1.26 to 1.78), and antihypertensive combination therapy (odds ratio, 1.29; 95% CI, 1.15 to 1.45) were significantly (Padherence to antihypertensive treatment. Compared with their low-adherence counterparts, only high adherers reported a significantly decreased risk of acute cardiovascular events (hazard ratio, 0.62; 95% CI, 0.40 to 0.96; P=0.032). The long-term reduction of acute cardiovascular events associated with high adherence to antihypertensive treatment underscores its importance in assessments of the beneficial effects of evidence-based therapies in the population. An effort focused on early antihypertensive treatment initiation and adherence is likely to provide major benefits.

    Hypertension is the leading remediable risk factor for cardiovascular disease, affecting more than 1 billion people worldwide, and is responsible for more than 10 million preventable deaths globally each year. While hypertension can be successfully diagnosed and treated, only one in seven persons with hypertension have controlled blood pressure. To meet the challenge of improving the control of hypertension, particularly in low- and middle-income countries, the authors developed the Standardized Hypertension Treatment and Prevention Project, which involves a health systems-strengthening approach that advocates for standardized hypertension management using evidence-based interventions. These interventions include the use of standardized treatment protocols, a core set of medications along with improved procurement mechanisms to increase the availability and affordability of these medications, registries for cohort monitoring and evaluation, patient empowerment, team-based care (task shifting), and community engagement. With political will and strong partnerships, this approach provides the groundwork to reduce high blood pressure and cardiovascular disease-related morbidity and mortality.

    This article provides an approach to advance care planning (ACP) and goals of care communication in older adults with cardiovascular disease and multi-morbidity. The goal of ACP is to ensure that the medical care patients receive is aligned with their values and preferences. In this article, the authors outline common benefits and challenges to ACP for older adults with cardiovascular disease and multimorbidity. Recognizing that these patients experience diverse disease trajectories and receive care in multiple health care settings, the authors provide practical steps for multidisciplinary teams to integrate ACP into brief clinic encounters.

    2015-09-01

    Restless legs syndrome (RLS)/Willis-Ekbom disease (WED) has a significant negative effect on quality of life. The decreased quality of life is similar to that of other chronic diseases, such as diabetes type 2, depression, and osteoarthritis. RLS/WED disrupts sleep length, sleep quality, and daytime alertness. Sleep disruption can contribute to depression. RLS/WED has been associated with cardiovascular disease and high blood pressure, possibly because of increased sympathetic tone caused by periodic limb movements of sleep. RLS/WED is underdiagnosed, leading to chronic sleep disruption and daytime consequences. Patients with RLS/WED have decreased productivity at work, which potentially has far-reaching economic consequences.

    Full Text Available Abstract Background Type 2 diabetes mellitus and depression are highly prevalent diseases that are associated with an increased risk of cardiovascular disease and mortality. There is evidence about a bidirectional association between depressive symptoms and type 2 diabetes mellitus. However, prognostic implications of the joint effects of these two diseases on cardiovascular morbidity and mortality are not well-known. Method/design A three-year, observational, prospective, cohort study, carried out in Primary Health Care Centres in Madrid (Spain. The project aims to analyze the effect of depression on cardiovascular events, all-cause and cardiovascular mortality in patients with type 2 diabetes mellitus, and to estimate a clinical predictive model of depression in these patients. The number of patients required is 3255, all them with type 2 diabetes mellitus, older than 18 years, who regularly visit their Primary Health Care Centres and agree to participate. They are chosen by simple random sampling from the list of patients with type 2 diabetes mellitus of each general practitioner. The main outcome measures are all-cause and cardiovascular mortality and cardiovascular morbidity; and exposure variable is the major depressive disorder. There will be a comparison between depressed and not depressed patients in all-cause mortality, cardiovascular mortality, coronary artery disease and stroke using the Chi-squared test. Logistic regression with random effects will be used to adjust for prognostic factors. Confounding factors that might alter the effect recorded will be taken into account in this analysis. To assess the effect of depression on the mortality, a survival analysis will be used comparing the two groups using the log-rank test. The control of potential confounding variables will be performed by the construction of a Cox regression model. Discussion Our study’s main contribution is to evaluate the increase in the risk of

Conclusion. Generally, PD had a significant influence on cardiovascular morbidity in the treated patients, especially on the left ventricular function and peripherial atherosclerosis. The age of the patients had more influence on acceleration of atherosclerosis than the length of dialysis or biocompatibility of dialysis solutions.

    Incidence of chronic heart failure (HF) increases with age and cardiovascular (CV) morbidity. Co-morbidities increase hospitalization and mortality in HF, and non-CV co-morbidities may lead to preventable hospitalizations. We studied the impact of co-morbidities on mortality and morbidity in Systolic Heart Failure Treatment with the I(f) Inhibitor Ivabradine Trial, and investigated whether the impact of ivabradine was affected by co-morbidities. We analyzed the Systolic Heart Failure Treatment with the I(f) Inhibitor Ivabradine Trialpopulation, with moderate-to-severe HF and left ventricular dysfunction (in sinus rhythm with heart rate at rest ≥70 beats/min), according to co-morbidity: chronic obstructive pulmonary disease, diabetes mellitus, anemia, stroke, impaired renal function, myocardial infarction, hypertension, and peripheral artery disease. Co-morbidity load was classed as 0, 1, 2, 3, 4+ or 1 to 2 co-morbidities, or 3+ co-morbidities. Co-morbidities were evenly distributed between the placebo and ivabradine groups. Patients with more co-morbidities were likely to be older, women, had more advanced HF, were less likely to be on β blockers, with an even distribution on ivabradine 2.5, 5, or 7.5 mg bid and placebo at all co-morbidity loads. Number of co-morbidities was related to outcomes. Cardiovascular death or HF hospitalization events significantly increased (p 3 co-morbidities for both, ivabradine and placebo. There was no interaction between co-morbidity load and the treatment effects of ivabradine. Hospitalization rate was lower at all co-morbidity loads for ivabradine. In conclusion, cardiac and noncardiac co-morbidities significantly affect CV outcomes, particularly if there are >3 co-morbidities. The effect of heart rate reduction with ivabradine is maintained at all co-morbidity loads.

    Full Text Available Abstract Background Measuring the real burden of cardiovascular disease in Australian Aboriginals is complicated by under-identification of Aboriginality in administrative health data collections. Accurate data is essential to measure Australia's progress in its efforts to intervene to improve health outcomes of Australian Aboriginals. We estimated the under-ascertainment of Aboriginal status in linked morbidity and mortality databases in patients hospitalised with cardiovascular disease. Methods Persons with public hospital admissions for cardiovascular disease in Western Australia during 2000-2005 (and their 20-year admission history or who subsequently died were identified from linkage data. The Aboriginal status flag in all records for a given individual was variously used to determine their ethnicity (index positive, and in all records both majority positive or ever positive and stratified by region, age and gender. The index admission was the baseline comparator. Results Index cases comprised 62,692 individuals who shared a total of 778,714 hospital admissions over 20 years, of which 19,809 subsequently died. There were 3,060 (4.9% persons identified as Aboriginal on index admission. An additional 83 (2.7% Aboriginal cases were identified through death records, increasing to 3.7% when cases with a positive Aboriginal identifier in the majority (≥50% of previous hospital admissions over twenty years were added and by 20.8% when those with a positive flag in any record over 20 years were incorporated. These results equated to underestimating Aboriginal status in unlinked index admission by 2.6%, 3.5% and 17.2%, respectively. Deaths classified as Aboriginal in official records would underestimate total Aboriginal deaths by 26.8% (95% Confidence Interval 24.1 to 29.6%. Conclusions Combining Aboriginal determinations in morbidity and official death records increases ascertainment of unlinked cardiovascular morbidity in Western Australian

    The study examines effects of hot spells on cardiovascular disease (CVD) morbidity and mortality in the population of the Czech Republic, with emphasis on differences between ischaemic heart disease (IHD) and cerebrovascular disease (CD) and between morbidity and mortality. Daily data on CVD morbidity (hospital admissions) and mortality over 1994-2009 were obtained from national hospitalization and mortality registers and standardized to account for long-term changes as well as seasonal and weekly cycles. Hot spells were defined as periods of at least two consecutive days with average daily air temperature anomalies above the 95 % quantile during June to August. Relative deviations of mortality and morbidity from the baseline were evaluated. Hot spells were associated with excess mortality for all examined cardiovascular causes (CVD, IHD and CD). The increases were more pronounced for CD than IHD mortality in most population groups, mainly in males. In the younger population (0-64 years), however, significant excess mortality was observed for IHD while there was no excess mortality for CD. A short-term displacement effect was found to be much larger for mortality due to CD than IHD. Excess CVD mortality was not accompanied by increases in hospital admissions and below-expected-levels of morbidity prevailed during hot spells, particularly for IHD in the elderly. This suggests that out-of-hospital deaths represent a major part of excess CVD mortality during heat and that for in-hospital excess deaths CVD is a masked comorbid condition rather than the primary diagnosis responsible for hospitalization.

    Abstract Background Cardiovascular disease (CVD) is the leading cause of morbidity and mortality in patients with chronic kidney disease (CKD). Cardiovascular risk assessment in this population is hampered by the failure of traditional risk factors to fully account for the elevated CVD risk (reverse epidemiology effect) and the presence of emerging risk factors specifically related to kidney failure. Therefore, diagnostic tools capable of improving cardiovascular risk assessment beyond tradit...

  17. Morbidity and mortality of orthostatic hypotension: implications for management of cardiovascular disease.

    Science.gov (United States)

    Benvenuto, Luke J; Krakoff, Lawrence R

    2011-02-01

    Orthostatic hypotension (OH) is the failure of cardiovascular reflexes to maintain blood pressure on standing from a supine or sitting position. Although OH may cause symptoms of dizziness or syncope, asymptomatic OH (AOH) is far more common and is an independent risk factor for mortality and cardiovascular disease (CVD). The prevalence of AOH increases with age, the presence of hypertension or diabetes and the use of antihypertensive or other medications. The implications of AOH for the treatment of CVD and hypertension are not well defined. This review provides an overview of the current information on this topic and recommends the more frequent assessment of OH in clinical practice and in future clinical trials.

    2015-01-01

    Background There is no consensus regarding whether androgen deprivation therapy (ADT) is associated with cardiovascular disease (CVD) and cardiovascular mortality (CVM). The objective of this study was to determine the role of ADT for prostate cancer (PCa) in development of cardiovascular events (CVD and CVM). Methods and findings We performed a meta-analysis from population-based observational studies comparing ADT vs control aimed at treating PCa in patients with PCa, reporting either CVD or CVM as outcome. Publications were searched using Medline, Embase, Cochrane Library Central Register of observational studies database up to May 31th 2014, and supplementary searches in publications from potentially relevant journals. 6 studies were identified with a total of 129,802 ADT users and 165,605 controls investigating the relationship between ADT and CVD. The incidence of CVD was 10% higher in ADT groups, although no significant association was observed (HR =1.10, 95% CIs: 1.00-1.21; P=0.06). For different types of ADT, CVD was related with gonadotropin-releasing hormone (GnRH) (HR =1.19, 95% CIs: 1.04-1.36; P<0.001) and GnRH plus oral antiandrogen (AA) (HR =1.46, 95% CIs: 1.03-2.08; P=0.04), but not with AA alone or orchiectomy. For CVM, 119,625 ADT users and 150,974 controls from 6 eligible studies were included, pooled result suggested that ADT was associated with CVM (HR =1.17, 95% CIs: 1.04-1.32; P=0.01). Significantly increased CVM was also detected in GnRH and GnRH plus AA groups. When patients received other treatments (e.g., prostatectomy and radiotherapy) were ruled out of consideration, more increased CVD (HR =1.19, 95% CIs: 1.08-1.30; P<0.001) and CVM (HR =1.30, 95% CIs: 1.13-1.50; P<0.001) were found in men treated with ADT monotherapy. Conclusions ADT is associated with both CVD and CVM. Particularly, GnRH alone and GnRH plus AA can significantly increase the incidence of cardiovascular events in patients with PCa.

    Full Text Available Purpose. Depression and antidepressant use may independently increase the risk of acute myocardial infarction and mortality in adults. However, no studies have looked at the effect of depression on a broader thrombotic event outcome, assessed antidepressant use, or evaluated elderly adults. Methods. A cohort of 7,051 community-dwelling elderly beneficiaries who experienced a thrombotic cardiovascular event (TCE were pooled from the 1997 to 2002 Medicare Current Beneficiary Survey and followed for 12 months. Baseline characteristics, antidepressant utilization, and death were ascertained from the survey, while indexed TCE, recurrent TCE, and depression (within 6 months of indexed TCE were taken from ICD-9 codes on Medicare claims. Time to death and first recurrent TCE were assessed using descriptive and multivariate statistics. Results. Of the elders with a depression claim, 71.6% had a recurrent TCE and 4.7% died within 12 months of their indexed TCE, compared to 67.6% and 3.9% of those elders without a depression claim. Of the antidepressant users, 72.6% experienced a recurrent TCE and 3.9% died, compared to 73.7% and 4.6% in the subset of selective serotonin reuptake inhibitor (SSRI users. Depression was associated with a shorter time to death (P=.008 in the unadjusted analysis. However, all adjusted comparisons revealed no effect by depression, antidepressant use, or SSRI use. Conclusions. Depression was not associated with time to death or recurrent TCEs in this study. Antidepressant use, including measures of any antidepressant use and SSRI use, was not associated with shorter time to death or recurrent TCE.

    Previous studies suggest that patients with hyperthyroidism remain at an increased risk of cardiovascular morbidity even after restoring euthyroidism. The mechanisms of the increased risk and its dependency on the different treatment modalities of hyperthyroidism remain unclear. The aim of this long-term follow-up study was to compare the rate of hospitalizations for cardiovascular causes and the mortality in hyperthyroid patients treated surgically with an age- and gender-matched reference population. A population-based cohort study was conducted among 4334 hyperthyroid patients (median age 46 years) treated with thyroidectomy in 1986-2007 in Finland and among 12,991 reference subjects. Firstly, the hospitalizations due to cardiovascular diseases (CVD) were analysed until thyroidectomy. Secondly, the hazard ratios for any new hospitalization due to CVDs after the thyroidectomy were calculated in Cox regression analysis adjusted with the prevalent CVDs at the time of thyroidectomy. The risk of hospitalization due to all CVDs started to increase already 5 years before the thyroidectomy, and by the time of the operation, it was 50% higher in the hyperthyroid patients compared to the controls (P hyperthyroidism. Despite the increased CVD morbidity among the patients, there was no difference in cardiovascular mortality. The present study shows that hyperthyroidism increases the risk of hospitalization due to CVDs and the risk is sustained up to two decades after effective surgical treatment. However, there was no excess CVD mortality in the middle-aged patient cohort studied. © 2013 John Wiley & Sons Ltd.

    Full Text Available Objective: To identify individuals at high cardiovascular risk (CVR to check for an additional estimate of CVR with the use of the ESH/ESC Guidelines (2003, 2007 in patients earlier classified as being at low and moderate risk on «SCORE». Material and methods: The study included 600 people (155 men and 445 women with low and moderate cardiovascular risk on the SCORE scale. All patients were examined with duplex scanning of the carotid arteries (DSCA to the determined of the thickness of the intima – media (IMT, the presence of atherosclerotic plaques (ASP; it has also been performed sphygmographic computer (SC with automatic estimation of brachial-ankle pulse wave velocity (baPWV, biochemical analysis of blood lipid spectrum. Results: The frequency of ASP was 59.5% (357 out of 600, and a thickening of thecomplex "intima-media" (IMT> 0.9 mm was detected in only 5% of the cases (28 persons out of 600, that indicated a slight contribution to the magnitude of the risk of such parameters as the IMT. The total number of patients with signs of preclinicallesions of the arterial wall (the presence of ASP and/or increased baPWV was 337 (56% of 600. Our results showed that the presence of subclinical atherosclerosis is in itself a risk factor. Conclusion: The usage of instrumental methods of research (DSCA, SC allowed to detect 32% of individuals with high CVR from 600 previously classified as low and moderate risk on SCORE scale. In our opinion, the proposed algorithm is convenient and easy to use for transfer of the patients into high-risk group.

    risk factors and cardiovascular morbidity in the oldest old (>80 years old residing at the municipality of Veranópolis - RS, Brazil. METHODOS: 196 elderly participated in the study (69 male and 127 female, 91% of the population aged >80 until June, 1996. For obesity evaluation and classification, we used the body mass index (BMI and the World Health Organization (WHO and National Health and Nutrition Examination Survey (NHANES III criteria. The cardiovascular risk factors investigated were sex, age, systemic hypertension, hypercholesterolemia, hypertriglyceridemia, diabetes mellitus (DM and smoking. For cardiovascular morbidities, we considered acute myocardial infarction, intermittent claudication and stroke. Waist-hip ratio (W/H, regular consumption of alcoholic beverages and physical activity were investigated too. Results: the obesity prevalence was 23.3% according to WHO (without difference between sex, p=0.124 and 45.6% according to NHANES III criteria (significantly higher in female, p=0.05. Obesity associations with risk factors were sex-dependent (the obese females presented higher levels of systolic blood pressure and glucose, lower levels of HDL-c, and higher systemic hypertension and DM frequencies; while the obese males presented higher levels of diastolic blood pressure, total cholesterol, LDL-c and higher hypercholesterolemia frequency. W/H and triglycerides, as well as hypertriglyceridemia frequency, were higher in obese people. CONCLUSIONS: the obesity prevalence was high among the long-living elderly, and its association with cardiovascular risk factors was sex-dependent. As regards morbidities, we did not observe differences between obese and non-obese people.

    Full Text Available Abstract Background Co-morbid major depressive disorder (MDD and cardiovascular disease (CVD is associated with poor clinical and psychological outcomes. However, the full extent of the burden of, and interaction between, this co-morbidity on important vocational outcomes remains less clear, particularly at the population level. We examine the association of co-morbid MDD with work outcomes in persons with and without CVD. Methods This study utilised cross-sectional, population-based data from the 2007 Australian National Survey of Mental Health and Wellbeing (n = 8841 to compare work outcomes of individuals with diagnostically-defined MDD and CVD, MDD but not CVD, CVD but not MDD, with a reference group of "healthy" Australians. Workforce participation was defined as being in full- or part-time employment. Work functioning was measured using a WHO Disability Assessment Schedule item. Absenteeism was assessed using the 'days out of role' item. Results Of the four groups, those with co-morbid MDD and CVD were least likely to report workforce participation (adj OR:0.4, 95% CI: 0.3-0.6. Those with MDD only (adj OR:0.8, 95% CI:0.7-0.9 and CVD only (adj OR:0.8, 95% CI: 0.6-0.9 also reported significantly reduced odds of participation. Employed individuals with co-morbid MDD and CVD were 8 times as likely to experience impairments in work functioning (adj OR:8.1, 95% CI: 3.8- 17.3 compared with the reference group. MDD was associated with a four-fold increase in impaired functioning. Further, individuals with co-morbid MDD and CVD reported greatest likelihood of workplace absenteeism (adj. OR:3.0, 95% CI: 1.4-6.6. Simultaneous exposure to MDD and CVD conferred an even greater likelihood of poorer work functioning. Conclusions Co-morbid MDD and CVD is associated with significantly poorer work outcomes. Specifically, the effects of these conditions on work functioning are synergistic.

  16. Asymmetric Dimethylarginine Is a Well Established Mediating Risk Factor for Cardiovascular Morbidity and Mortality—Should Patients with Elevated Levels Be Supplemented with Citrulline?

    Science.gov (United States)

    McCarty, Mark F.

    2016-01-01

    The arginine metabolite asymmetric dimethylarginine (ADMA) is a competitive inhibitor and uncoupler of endothelial nitric oxide synthase (eNOS), an enzyme that acts in multifarious ways to promote cardiovascular health. This phenomenon likely explains, at least in part, why elevated ADMA has been established as an independent risk factor for cardiovascular events, ventricular hypertrophy, and cardiovascular mortality. Fortunately, the suppressive impact of ADMA on eNOS activity can be offset by increasing intracellular arginine levels with supplemental citrulline. Although the long-term impact of supplemental citrulline on cardiovascular health in patients with elevated ADMA has not yet been studied, shorter-term clinical studies of citrulline administration demonstrate effects suggestive of increased NO synthesis, such as reductions in blood pressure and arterial stiffness, improved endothelium-dependent vasodilation, increased erection hardness, and increased ejection fractions in patients with heart failure. Supplemental citrulline could be a practical option for primary or secondary prevention of cardiovascular events and mortality, as it is inexpensive, has a mild flavor, and is well tolerated in doses (3–6 g daily) that can influence eNOS activity. Large and long-term clinical trials, targeting patients at high risk for cardiovascular events in whom ADMA is elevated, are needed to evaluate citrulline’s potential for aiding cardiovascular health.

    Obstructive sleep apnea (OSA) has been associated with hypertension, which is one of the intermediary mechanisms leading to increased cardiovascular morbidity. This study aimed at evaluating the effects of a combination of continuous positive airway pressure (CPAP) and telemedicine support on blood pressure (BP) reduction in high cardiovascular risk OSA patients. A multi-center randomized controlled trial that compared standard CPAP care and CPAP care and a telemedicine intervention. Sleep clinics in France. 107 adult (18-65 years old) OSA patients (AHI > 15 events/h) with a high cardiovascular risk (cardiovascular SCORE > 5% or secondary prevention). Patients were randomized to either standard care CPAP (n = 53) or CPAP and telemedicine (n = 54). Patients assigned to telemedicine were equipped with a smartphone for uploading BP measurements, CPAP adherence, sleepiness, and quality of life data; in return, they received pictograms containing health-related messages. The main outcome was home self-measured BP and secondary outcomes were cardiovascular risk evolution, objective physical activity, CPAP adherence, sleepiness and quality of life. Self-measured BP did not improve in either group (telemedicine or standard care). Patients in primary prevention showed greater BP reduction with CPAP treatment than those in secondary prevention. CPAP treatment supported by telemedicine alone did not improve blood pressure and cardiovascular risk in high cardiovascular risk OSA patients. This study emphasizes the need for diet and physical activity training programs in addition to CPAP when aiming at decreasing cardiometabolic risk factors in these patients.

    Full Text Available Background and objectives: African American (AA children with focal segmental glomerulosclerosis (FSGS have later onset disease that progresses more rapidly than in non-AA children. It is unclear how APOL1 genotypes contribute to kidney disease risk, progression and cardiovascular morbidity in children. Design, setting, participants, & measurements: We examined the prevalence of APOL1 genotypes and associated cardiovascular phenotypes among children with FSGS in the Chronic Kidney Disease in Children (CKiD study; an ongoing multicenter prospective cohort study of children aged 1-16 years with mild to moderate kidney disease.Results: A total of 140 AA children in the CKiD study were genotyped. HR APOL1 genotypes were present in 24% of AA children (33/140 and were associated with FSGS, p 3 mg/L (33% vs. 15%, p=0.12 and obesity (48% vs. 19%, p=0.01. There were no differences in glomerular filtration rate, hemoglobin, iPTH, or calcium-phosphate product. Conclusions: AA children with HR APOL1 genotype and FSGS have increase prevalence of obesity and LVH despite a later age of FSGS onset, while adjusting for socioeconomic status. Treatment of obesity may be an important component of CKD and LVH management in this population.

    2010-07-01

    Full Text Available Abstract Background Cardiovascular disease (CVD is the leading cause of morbidity and mortality in patients with chronic kidney disease (CKD. Cardiovascular risk assessment in this population is hampered by the failure of traditional risk factors to fully account for the elevated CVD risk (reverse epidemiology effect and the presence of emerging risk factors specifically related to kidney failure. Therefore, diagnostic tools capable of improving cardiovascular risk assessment beyond traditional risk factors are currently warranted. We present the protocol of a 4-year prospective study aimed to assess the predictive value of non-invasive imaging techniques and biomarkers for CVD events and mortality in patients with CKD. Methods From November 2009 to October 2010, 4137 asymptomatic adult patients with stages 2 to 5 CKD will be recruited from nephrology services and dialysis units throughout Spain. During the same period, 843 participants without CKD (control group will be recruited from lists of primary care physicians, only at baseline. During the follow-up, CVD events and mortality will be recorded from all CKD patients. Clinical and laboratory characteristics will be collected in a medical documentation sheet. Three trained itinerant teams will carry out a carotid ultrasound to assess intima-media thickness and presence of plaques. A composite atherosclerosis score will be constructed based on carotid ultrasound data and measurement of ankle-brachial index. In CKD patients, presence and type of calcifications will be assessed in the wall of carotid, femoral and brachial arteries, and in cardiac valves, by ultrasound. From all participants, blood samples will be collected and stored in a biobank to study novel biomarkers. Conclusions The NEFRONA study is the first large, prospective study to examine the predictive value of several non-invasive imaging techniques and novel biomarkers in CKD patients throughout Spain. Hereby, we present the

    Full Text Available Cardiovascular calcification is prevalent in the aging population and in patients with chronic kidney disease (CKD and diabetes mellitus, giving rise to substantial morbidity and mortality. Vitamin K-dependent matrix Gla-protein (MGP is an important inhibitor of calcification. The aim of this study was to evaluate the impact of high-dose menaquinone-7 (MK-7 supplementation (100 µg/g diet on the development of extraosseous calcification in a murine model. Calcification was induced by 5/6 nephrectomy combined with high phosphate diet in rats. Sham operated animals served as controls. Animals received high or low MK-7 diets for 12 weeks. We assessed vital parameters, serum chemistry, creatinine clearance, and cardiac function. CKD provoked increased aortic (1.3 fold; p < 0.05 and myocardial (2.4 fold; p < 0.05 calcification in line with increased alkaline phosphatase levels (2.2 fold; p < 0.01. MK-7 supplementation inhibited cardiovascular calcification and decreased aortic alkaline phosphatase tissue concentrations. Furthermore, MK-7 supplementation increased aortic MGP messenger ribonucleic acid (mRNA expression (10-fold; p < 0.05. CKD-induced arterial hypertension with secondary myocardial hypertrophy and increased elastic fiber breaking points in the arterial tunica media did not change with MK-7 supplementation. Our results show that high-dose MK-7 supplementation inhibits the development of cardiovascular calcification. The protective effect of MK-7 may be related to the inhibition of secondary mineralization of damaged vascular structures.

  6. Diabetes Drugs and Cardiovascular Safety

    Full Text Available Diabetes is a well-known risk factor of cardiovascular morbidity and mortality, and the beneficial effect of improved glycemic control on cardiovascular complications has been well established. However, the rosiglitazone experience aroused awareness of potential cardiovascular risk associated with diabetes drugs and prompted the U.S. Food and Drug Administration to issue new guidelines about cardiovascular risk. Through postmarketing cardiovascular safety trials, some drugs demonstrated cardiovascular benefits, while some antidiabetic drugs raised concern about a possible increased cardiovascular risk associated with drug use. With the development of new classes of drugs, treatment options became wider and the complexity of glycemic management in type 2 diabetes has increased. When choosing the appropriate treatment strategy for patients with type 2 diabetes at high cardiovascular risk, not only the glucose-lowering effects, but also overall benefits and risks for cardiovascular disease should be taken into consideration.

    The epidemiological transition has seen a trend from communicable to non-communicable diseases in developing countries. At the pinnacle of these chronic diseases is hypertension, pre-hypertension, diabetes and obesity. This leads to increased cardiovascular morbidity and mortality worldwide. In addition, environmental and behavioural changes such as lifestyle habits represent modifiable risk factors for the development of cardiovascular diseases. The Caribbean is not immune to this trend. This was a cross-sectional survey conducted between June and September 2009 and involved individuals 15-74 years of age. Age-gender was weighted to get as close a representative sample of the general population living in the British Virgin Islands (BVI) for more than two years to a total of 301 (n = 301, M: 144, F: 157; CI 95% +/- error 5%).

    Recent studies suggest that psychotic-like experiences may also act as markers for non-psychotic psychiatric disorders, which may indicate that the focus of research in individuals at high risk (HR) for psychosis needs updating. In this study we thoroughly examined the clinical and functional characteristics of a consecutive cohort of young people at HR for psychosis and compared them to a matched sample of healthy volunteers. Between February 2010 and September 2012 60 help-seeking HR individuals, aged 16-35, were recruited from CAMEO Early Intervention in Psychosis Service, Cambridgeshire, UK. Forty-five age- and gender-matched healthy volunteers were randomly recruited from the same geographical area. Sociodemographic, psychiatric morbidity, functioning and quality of life measures were compared between both groups. HR individuals suffered a wide range of DSM-IV psychiatric disorders, mainly within the affective and anxiety diagnostic spectra. In comparison to healthy volunteers, young people at HR reported more suicidal ideation/intention, depressive and anxiety symptoms and presented with remarkably poor functioning and quality of life. The presence of co-morbid moderate or severe depressive and anxiety symptoms was common in our sample of young people at enhanced risk for psychosis. A HR mental state may be associated not only with an increased risk for psychosis, but also other psychiatric disorders. Our findings may have implications for the future implementation of therapeutic interventions that this population could benefit from. Copyright © 2013 Elsevier B.V. All rights reserved.

    Full Text Available Uno de los aspectos que más discusión ha suscitado en los últimos tiempos entre quienes nos dedicamos al estudio de la emoción tiene que ver con la eventual asociación entre percepción, valoración y respuesta fisiológica. Esto es, siguiendo la máxima aristotélica, cabría cuestionar si las cosas son como son o son como cada quien las percibe. El objetivo de este experimento ha sido establecer la existencia de una conexión entre percepción de control y responsividad cardiovascular. La muestra estudiada ha estado conformada por estudiantes de la Universidad de Castellón; todos ellos han participado de forma voluntaria. La prueba de estrés ha consistido en un examen real de una asignatura troncal de la titulación que cursaban los participantes. Así pues, utilizando una situación de estrés real, hipotetizamos que las respuestas cardiovasculares (medidas a través de la tasa cardiaca, la presión sanguínea sistólica y la presión sanguínea diastólica dependen de la percepción de control que el individuo tiene, o cree tener, sobre la situación.

  13. High sensitivity troponin in cardiovascular disease. Is there more than a marker of myocardial death?

    Cardiovascular disease is the leading cause of death worldwide and coronary artery disease is its most prevalent manifestation, associated with high mortality and morbidity. In clinical practice cardiac troponins (cTn) are the cornerstone of the diagnosis, risk stratification and thus selection of the optimal treatment strategy in patients with acute coronary syndrome. According to the third update of the universal definition of myocardial infarction (MI) cTn is the preferred cardiac biomarker of myocardial necrosis in the setting of acute myocardial ischemia. Over the last years newer high sensitivity cardiac troponin (hs-cTn) assays have been developed that are more sensitive than conventional assays, have low limit of detection, low imprecision and low reference limits, but due to variability, the deployment of a standardization and harmonization method is required before their wide use in clinical practice. Recent studies have shown that their utilization seems to improve the diagnostic accuracy detecting MI in patients presenting with chest pain. However, the improved sensitivity comes along with a decreased specificity, though serial cTn measurements and the detection of early changes could improve the specificity and the overall diagnostic performance. Moreover, apart from their use in the diagnosis and risk stratification of MI and acute coronary syndromes, hs-cTn assays seem to have a key role in risk stratification and short and long-term prognosis in a variety of cardiovascular modalities such as stable coronary disease, heart failure and acute pulmonary embolism. In addition, studies have suggested that cTns may be used as a biomarker in the primary prevention of cardiovascular disease leading to the identification of high-risk populations or individuals with silent heart disease.

    ACCOMPLISH is the first trial designed to compare the effects on major fatal and non-fatal cardiovascular endpoints of two forms of antihypertensive combination therapy: benazepril plus hydrochlorothiazide and amlodipine plus benazepril in hypertensive patients at high cardiovascular risk. Enrollment for this trial is now complete and this report describes the clinical characteristics of the study cohort. Patients with hypertension and a previous history of cardiovascular events, strokes or diabetes mellitus were randomized to double-blind treatment with either of the two combination regimens. The data in this report detail the clinical history and demographic characteristics in patients immediately prior to randomization to study drugs. A total of 11,454 patients were randomized. Mean age (+/-SD) was 68.4+/-6.9 years, 60% were men, and 1360 (12%) were African American. Mean body mass index (BMI) was 31.0+/-6.3 kg/m(2). At study entry, 46% of patients had a history of acute coronary syndromes, coronary artery bypass grafts or percutaneous coronary interventions; 13% had a history of stroke. A history of diabetes mellitus was reported in 6928 (60%) of patients. Mean blood pressure at baseline (on prior hypertension therapy) was 145.4/80.0 mmHg; only 38% of patients had a BP less than 140/90 mmHg. Overall, 97% of patients had received previous antihypertensive treatment (74% on at least two drugs); 53% were on oral diabetes therapy or insulin, 68% on anti-lipid therapy and 63% on anti-platelet agents. In summary, the ACCOMPLISH trial has recruited hypertensive patients at high risk of cardiovascular morbidity and mortality. It is noteworthy that the mean BMI of 31 in this cohort is clearly above the accepted diagnostic criterion of obesity and that 60% of patients are diabetic, possibly reflecting secular trends in clinical disease.

  15. High Lung Allocation Score Is Associated With Increased Morbidity and Mortality Following Transplantation

    Background: The lung allocation score (LAS) was initiated in May 2005 to allocate lungs based on medical urgency and posttransplant survival. The purpose of this study was to determine if there is an association between an elevated LAS at the time of transplantation and increased postoperative morbidity and mortality. Methods: The United Network for Organ Sharing provided de-identified patient-level data. Analysis included lung transplant recipients aged ≥ 12 years who received transplants between April 5, 2006, and December 31, 2007 (n = 3,836). Recipients were stratified into three groups: LAS < 50 (n = 3,161, 83.87%), LAS 50 to 75 (n = 411, 10.9%), and LAS ≥ 75 (n = 197, 5.23%), referred to as low LAS (LLAS), intermediate LAS (ILAS), and high LAS (HLAS), respectively. The primary outcome was posttransplant graft survival at 1 year. Secondary outcomes included length of stay and in-hospital complications. Results: HLAS recipients had significantly worse actuarial survival at 90 days and 1 year compared with LLAS recipients. When transplant recipients were stratified by disease etiology, a trend of decreased survival with elevated LAS was observed across all major causes of lung transplant. HLAS recipients were more likely to require dialysis or to have infections compared with LLAS recipients (P < .001). In addition, length of stay was higher in the HLAS group when compared with the LLAS group (P < .001). Conclusions: HLAS is associated with decreased survival and increased complications during the transplant hospitalization. Whereas the LAS has improved organ allocation through decreased waiting list deaths and waiting list times, lower survival and higher morbidity among HLAS recipients suggests that continued review of LAS scoring is needed to ensure optimal long-term transplant survival.

    Atherogenic dyslipidemia is an important risk factor for cardiovascular disease. We aim to determine atherogenic dyslipidemia prevalence in primary care patients at moderate-very high cardiovascular risk and its associated cardiovascular risk perception in Spain. This cross-sectional study included 1137 primary care patients. Patients had previous cardiovascular disease, diabetes mellitus, SCORE risk ≥ 3, severe hypertension or dyslipidemia. Atherogenic dyslipidemia was defined as low HDL-C (triglycerides (≥ 150 mg/dL). A visual analog scale was used to define a perceived cardiovascular disease risk score. Mean age was 63.9 ± 9.7 years (64.6% males). The mean BMI was 29.1 ± 4.3 kg/m(2), and mean waist circumference 104.2 ± 12.7 cm (males), and 97.2 ± 14.0 cm (females). 29.4% were smokers, 76.4% had hypertension, 48.0% were diabetics, 24.7% had previous myocardial infarction, and 17.8% peripheral arterial disease. European guidelines classified 83.6% at very high cardiovascular risk. Recommended HDL-C levels were achieved by 50.1% of patients and 37.3% had triglycerides in the reference range. Target LDL-C was achieved by 8.8%. The overall atherogenic dyslipidemia prevalence was 27.1% (34.1% in diabetics). This prevalence in patients achieving target LDL-C was 21.4%. Cardiovascular risk perceived by patients was 4.3/10, while primary care physicians scored 5.7/10. When LDL-C levels are controlled, atherogenic dyslipidemia is more prevalent in those patients at highest cardiovascular risk and with diabetes. This highlights the importance of intervention strategies to prevent the residual vascular risk in this population. Both patients and physicians underestimated cardiovascular risk.

    Full Text Available Recently the use of indoor residual spraying of insecticide (IRS has greatly increased in Africa; however, limited data exist on the quantitative impacts of IRS on health outcomes in highly malaria endemic areas.Routine data were collected on more than 90,000 patient visits at a single health facility over a 56 month period covering five rounds of IRS using three different insecticides. Temporal associations between the timing of IRS and the probability of a patient referred for microscopy having laboratory confirmed malaria were estimated controlling for seasonality and age. Considering patients less than five years of age there was a modest decrease in the odds of malaria following the 1(st round of IRS using DDT (OR = 0.76, p<0.001 and the 2(nd round using alpha-cypermethrin (OR = 0.83, p = 0.002. Following rounds 3-5 using bendiocarb there was a much greater decrease in the odds of malaria (ORs 0.34, 0.16, 0.17 respectively, p<0.001 for all comparisons. Overall, the impact of IRS was less pronounced among patients 5 years or older.IRS was associated with a reduction in malaria morbidity in an area of high transmission intensity in Uganda and the benefits appeared to be greatest after switching to a carbamate class of insecticide.

    Full Text Available Background: The prevalence of asthma and other respiratory diseases among children and adolescents has been on the rise in recent years and this can affect the quality of life and scholastic performance of school students. Therefore, it is essential to find out the actual prevalence of respiratory morbidity among high school students so that we can plan early interventions against this problem. Methods: A cross sectional study was conducted among the students from classes 8 to 10, from a public school in Pathanamthitta district of Kerala state, using a modified American Thoracic Society Questionnaire (ATS-DLD-78-A to assess respiratory symptoms among general population. Results: The prevalence of cough was 40.8% (95% CI 34.8% to 46.9% and that of wheeze was found to be 19.6% (95% CI 15.1% to 24.9%. Among the possible risk factors for developing respiratory diseases, it was found that only family history of respiratory problems had a significant association with symptoms of respiratory disease (P = 0.002. Conclusion: The very high prevalence of respiratory symptoms in the study may be due to the fact that the study was conducted during the rainy season in which there is a higher incidence of respiratory infections. But these findings point towards the need to conduct more comprehensive and objective studies on the subject. [Int J Res Med Sci 2015; 3(5.000: 1149-1152

    The ACCOMPLISH trial (Avoiding Cardiovascular events through Combination therapy in Patients Living with Systolic Hypertension) was a 3-year multicenter, event-driven trial involving patients with high cardiovascular risk who were randomized in a double-blinded manner to benazepril plus either hydrochlorothiazide or amlodipine and titrated in parallel to reach recommended blood pressure goals. Of the 8125 participants in the United States, 1414 were of self-described Black ethnicity. The composite kidney disease end point, defined as a doubling in serum creatinine, end-stage renal disease, or death was not different between Black and non-Black patients, although the Blacks were significantly more likely to develop a greater than 50% increase in serum creatinine to a level above 2.6 mg/dl. We found important early differences in the estimated glomerular filtration rate (eGFR) due to acute hemodynamic effects, indicating that benazepril plus amlodipine was more effective in stabilizing eGFR compared to benazepril plus hydrochlorothiazide in non-Blacks. There was no difference in the mean eGFR loss in Blacks between therapies. Thus, benazepril coupled to amlodipine was a more effective antihypertensive treatment than when coupled to hydrochlorothiazide in non-Black patients to reduced kidney disease progression. Blacks have a modestly higher increased risk for more advanced increases in serum creatinine than non-Blacks.

  2. Cardiovascular complications from consumption of high energy drinks: recent evidence.

    The energy drinks (ED) are caffeinated beverages that are popular among teenagers and young adults. They are aggressively marketed as providing alertness, energy and sex prowess. The EDs in addition to caffeine contain several plant stimulants and simple sugars, which increase their caloric content. The caffeine concentration in these drinks is high and their overconsumption could lead to insomnia, agitation, tremors and cardiovascular complications including sudden death. Alcohol is often mixed with EDs (AMEDs) in the wrong perception that the caffeine in the EDs will prevent the drowsiness and sleepiness from alcohol and allow the person to consume more alcohol. This false perception, could lead to alcohol intoxication and the taking of risky decisions, like driving under the influence of alcohol and the risk of serious physical harm to themselves and others. To prevent the problem of consumption of EDs and AMEDs, the caring physician could help by advising the parents and his young patients about the serious health risks from the consumption of these drinks. In order to grasp the extend of the problem of ED and AMED consumption, we did a Medline search of the English language literature from January 2010 to December 2013, using the terms EDs and alcohol-mixed EDs. All the findings from the recent studies regarding the cardiovascular complications from the consumption of EDs and AMEDs together with collateral literature will be discussed in this review.

    The rising number of obese patients poses new challenges for burn care. These may include adjustments in calculations of burn size, resuscitation, ventilator wean, nutritional goals as well as challenges in mobilization. The authors have focused this observational study on resuscitation in the obese patient population in the first 48 hours after burn injury. Previous trauma studies suggest a prolonged time to reach end points of resuscitation in the obese compared to nonobese injured patients. The authors hypothesize that obese patients have worse outcomes after thermal injury and that differences in the response to resuscitation contribute to this disparity. The authors retrospectively analyzed data prospectively collected in a multicenter trial to compare resuscitation and outcomes in patients stratified by National Institutes of Health/World Health Organization body mass index (BMI) classification (BMI: normal weight, 18.5-24.9; overweight, 25-29.9, obese, 30-39.9; morbidly obese, ≥40). Because of the distribution of body habitus in the obese, total burn size was recalculated for all patients by using the method proposed by Neaman and compared with Lund-Browder estimates. The authors analyzed patients by BMI class for fluids administered and end points of resuscitation at 24 and 48 hours. Multivariate analysis was used to compare morbidity and mortality across BMI groups. The authors identified 296 adult patients with a mean TBSA of 41%. Patient and injury characteristics were similar across BMI categories. No significant differences were observed in burn size calculations by using Neaman vs Lund-Browder formulas. Although resuscitation volumes exceeded the predicted formula in all BMI categories, higher BMI was associated with less fluid administered per actual body weight (P = .001). Base deficit on admission was highest in the morbidly obese group at 24 and 48 hours. Furthermore, the morbidly obese patients did not correct their metabolic acidosis to the

    Full Text Available Abstract Background Self-reported health perceptions such as physical distress and quality of life are suggested independent predictors of mortality and morbidity in patients with established cardiovascular disease. This study examined the associations between these factors and three years incidence of cardiovascular events in a population of elderly men with long term hyperlipidemia. Methods We studied observational data in a cohort of 433 men aged 64–76 years from a prospective, 2 × 2 factorial designed, three-year interventional trial. Information of classical risk factors was obtained and the following questionnaires were administered at baseline: Hospital Anxiety and Depression Scale, Physical Symptom Distress Index and Life Satisfaction Index. The occurrence of cardiovascular death, myocardial infarction, cerebrovascular incidences and peripheral arterial disease were registered throughout the study period. Continuous data with skewed distribution was split into tertiles. Hazard ratios (HR were calculated from Cox regression analyses to assess the associations between physical distress, quality of life and cardiovascular events. Results After three years, 49 cardiovascular events were registered, with similar incidence among subjects with and without established cardiovascular disease. In multivariate analyses adjusted for age, smoking, systolic blood pressure, serum glucose, HADS-anxiety and treatment-intervention, physical distress was positively associated (HR 3.1, 95% CI 1.2 – 7.9 for 3rd versus 1st tertile and quality of life negatively associated (HR 2.6, 95% CI 1.1–5.8 for 3rd versus 1st tertile with cardiovascular events. The association remained statistically significant only for physical distress (hazard ratio 2.8 95% CI 1.2 – 6.8, p Conclusion Physical distress, but not quality of life, was independently associated with increased risk of cardiovascular events in an observational study of elderly men predominantly

    V. Pascual Fuster

    Full Text Available Dyslipaemia is one of the main risk factors in the development of cardiovascular diseases. Currently, there are different alternatives available (amongst which statins occupy a pre-eminent place, to optimise the treatment of patients at high or very high cardiovascular risk. Despite this, the percentage of patients that achieve good lipid control is low. The causes of the mismatch with proposed objectives include lack of patient adherence and therapeutic inertia. This review uses available evidence and the latest clinical guides as a basis to assess the pharmacological treatment of dyslipaemia in patients with a background of arteriosclerotic vascular disease, diabetes, chronic kidney disease, cardiovascular risk at ≥5% calculated by SCORE and familial hypercholesterolaemia. The treatment of hypertriglyceridemia is also reviewed along with the special consideration that poly-pharmacy deserves in patients treated with statins, making mention of the treatment of dyslipaemia with HIV infection. The global assessment of cardiovascular risk is of high priority to adapt treatment to the specific objectives of the c-LDL for each risk category.

    We have previously associated SNP 894G>T in the NOS3 gene with diabetic nephropathy (DN) using multi-locus analysis. Variant 894G>T has been widely studied as a DN susceptibility factor with contradictory results. In the present study we genotyped 894G>T in the cohort of prospectively followed type 2 diabetics with the aim to investigate its possible role in the progression of DN and development of morbidity and mortality associated with diabetes. 311 subjects with defined stage of DN were enrolled in the study and followed up for a median of 38 months. We considered three end-points: progression of DN, major cardiovascular event and all-cause mortality. Considering baseline GFR, age at enrolment and diabetes duration as confounders, Cox regression analysis identified 894GT genotype as a risk factor for DN progression (HR = 1.843 [95% CI 1.088 - 3.119], P = 0.023) and 894TT genotype as a risk factor for major cardiovascular event (HR = 2.515 [95% CI 1.060 - 5.965], P = 0.036). We ascertained the significant effect of the NOS3 894G>T variant on DN progression and occurrence of major cardiovascular event in T2DM subjects. Based on these results NOS3 can be considered a modifier gene for DN.

    Full Text Available Background: Urban population growth in developing countries especially in India is at a rapid pace in the past few decades. Growth of urban population is always accompanied by the growth of population in urban slums, which poses threat to the health of urban population, particularly, the health of the children. Objective: The present study aims to study whether the slum dwelling affects the child morbidity, low weight at birth, infant mortality, child malnutrition and anemia.  Methods: Until NFHS-3, there was paucity of data on slums to analyze for a larger area and compare it with non-slum population. However, NFHS-3 provides data from slums in eight cities and is used for the present study. The child health aspects considered here are: prevalence of diarrhea among children, prevalence of fever among children, prevalence of cough among children, infant death, low birth weight, malnutrition among children and anemia among children. Results: Slum children belong to lower socioeconomic strata than children from non-slum areas. Children living in slum areas are 1.3 times, 1.5 times and 1.2 times more likely to suffer from diarrhea, cough and fever respectively than children living in non-slum areas. Multivariate results also showed that slum children have higher odds for low weight at birth (1.4 times and child anemia (1.2 times compared to non-slum children. Conclusion: Slum dwelling children are at a disadvantageous side in terms of child morbidity, anemia and weight at the time of birth.

    Recent evidence suggests that strain variation in the serum IgG response to Porphyromonas gingivalis occurs in periodontal disease and cardiovascular disease (CVD). This study aimed to test the hypothesis that different P. gingivalis strains would elicit different levels of IgG, depending on a patient's cardiovascular (CV) and periodontal health. For CVD patients, serum antibody levels increased significantly with increasing numbers of deep pockets for all strains of P. gingivalis, except W50 (p immune response to P. gingivalis in the relationship between periodontal disease and CVD.

    Antecedentes: Los estudios de receptor de GLP-1 se han dirigido a la identificación de polimorfismos en el gen receptor de GLP- 1 que pueden ser un factor que contribuye en la patogénesis de la diabetes mellitus y factores de riesgo cardiovascular. Sin embargo, el papel de las variantes del receptor de GLP-1 variantes en el peso corporal, factores de riesgo cardiovasculares y adipocitoquinas sigue estando poco estudiado en pacientes con obesidad morbida. Objetivo: Nuestro objetivo fue analizar los efectos del polimorfismo del receptor de GLP-1 rs6923761 sobre el peso corporal, factores de riesgo cardiovascular y los niveles de adipocitoquinas séricas en pacientes con obesidad mórbida. Diseño: Se estudió una muestra de 175 obesos mórbidos. La glucosa en ayunas, proteína C reactiva (PCR), insulina, resistencia a la insulina ( HOMA), colesterol total, LDL- colesterol, HDL- colesterol, triglicéridos y la concentración de adipoquinas se midieron. También se determinaron el peso, índice de masa corporal, circunferencia de la cintura, masa grasa a través de bioimpedancia y la presión arterial. Resultados: Un total de 87 obesos (49,7%) tenían el genotipo GG y 88 (50,3%) de los sujetos del estudio tenían los siguientes genotipos; GA (71 obesos, el 40,6%) o AA (17 sujetos del estudio, el 9,7%) ( segundo grupo) . En el grupo con genotipo GG, los niveles de glucosa (4,4 ± 2,3 mg/dl, p < 0,05), triglicéridos (6,8 ± 4,3 mg/dl , p < 0,05), insulina (4,5 ± 2,3 UI/l , p < 0,05) y HOMA (1,5 ± 0,9 unidades, p < 0,05 ) fueron mayores que en el grupo mutante. No se detectaron diferencias en el resto de parámetros analizados Conclusión: Existe una asociación entre los parámetros metabólicos y el alelo mutante (A) del polimorfismo rs6923761 del receptor de GLP- 1 en pacientes con obesidad mórbida. Los niveles de triglicéridos, insulina y resistencia a la insulina son más elevados en los sujetos portadores del alelo A.

    Oxidative stress induced interactions between fatty acid (FA) and one-carbon metabolism may be involved in co-occurrence of major depressive disorder (MDD) and cardiovascular disease (CVD), which have been scarcely studied together. In 137 recurrent MDD-patients vs. 73 age- and sex-matched healthy controls, we simultaneously measured key components of one-carbon metabolism in plasma (homocysteine, folate, vitamins B6 and B12), and of FA-metabolism in red blood cell membranes [main polyunsaturated fatty acids (PUFAs) eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and arachidonic acid (AA) and structural FA-indices (chain length, unsaturation, peroxidation)]. Results show significant positive associations of folate with EPA, DHA, and the peroxidation index, which were similar in patients and controls. After correction for confounders, these associations were lost except for EPA. Associations between B-vitamins and FA-parameters were non-significant, but also similar in patients and controls. Homocysteine and DHA were significantly less negatively associated in patients than in controls. In conclusion, these data indicate similarities but also differences in associations between parameters of one-carbon and FA-metabolism in recurrent MDD patients vs. controls, which may reflect differences in handling of oxidative stress. Further research should test the consequences of these differences, particularly the premature development of CVD in MDD.

    Itandehui Castro-Quezada

    Full Text Available OBJECTIVE: Different types of carbohydrates have diverse glycemic response, thus glycemic index (GI and glycemic load (GL are used to assess this variation. The impact of dietary GI and GL in all-cause mortality is unknown. The objective of this study was to estimate the association between dietary GI and GL and risk of all-cause mortality in the PREDIMED study. MATERIAL AND METHODS: The PREDIMED study is a randomized nutritional intervention trial for primary cardiovascular prevention based on community-dwelling men and women at high risk of cardiovascular disease. Dietary information was collected at baseline and yearly using a validated 137-item food frequency questionnaire (FFQ. We assigned GI values of each item by a 5-step methodology, using the International Tables of GI and GL Values. Deaths were ascertained through contact with families and general practitioners, review of medical records and consultation of the National Death Index. Cox regression models were used to estimate multivariable-adjusted hazard ratios (HR and their 95% CI for mortality, according to quartiles of energy-adjusted dietary GI/GL. To assess repeated measures of exposure, we updated GI and GL intakes from the yearly FFQs and used Cox models with time-dependent exposures. RESULTS: We followed 3,583 non-diabetic subjects (4.7 years of follow-up, 123 deaths. As compared to participants in the lowest quartile of baseline dietary GI, those in the highest quartile showed an increased risk of all-cause mortality [HR = 2.15 (95% CI: 1.15-4.04; P for trend  = 0.012]. In the repeated-measures analyses using as exposure the yearly updated information on GI, we observed a similar association. Dietary GL was associated with all-cause mortality only when subjects were younger than 75 years. CONCLUSIONS: High dietary GI was positively associated with all-cause mortality in elderly population at high cardiovascular risk.

  7. Indications for and utilization of angiotensin receptor II blockers in patients at high cardiovascular risk.

    The worldwide burden of cardiovascular disease is growing. In addition to lifestyle changes, pharmacologic agents that can modify cardiovascular disease processes have the potential to reduce cardiovascular events. Antihypertensive agents are widely used to reduce the risk of cardiovascular events partly beyond that of blood pressure-lowering. In particular, the angiotensin II receptor blockers (ARBs), which antagonize the vasoconstrictive and proinflammatory/pro-proliferative effects of angiotensin II, have been shown to be cardio vascularly protective and well tolerated. Although the eight currently available ARBs are all indicated for the treatment of hypertension, they have partly different pharmacology, and their pharmacokinetic and pharmacodynamic properties differ. ARB trials for reduction of cardiovascular risk can be broadly categorized into those in patients with/without hypertension and additional risk factors, in patients with evidence of cardiovascular disease, and in patients with severe cardiovascular disease, such as heart failure. These differences have led to their indications in different populations. For hypertensive patients with left ventricular hypertrophy, losartan was approved to have an indication for stroke prevention, while for most patients at high-risk for cardiovascular events, telmisartan is an appropriate therapy because it has a cardiovascular preventive indication. Other ARBs are indicated for narrowly defined high-risk patients, such as those with hypertension or heart failure. Although in one analysis a possible link between ARBs and increased risks of cancer has surfaced, several meta-analyses, using the most comprehensive data available, have found no link between any ARB, or the class as a whole, and cancer. Most recently, the US Food and Drug Administration completed a review of the potential risk of cancer and concluded that treatment with an ARB medication does not increase the risk of developing cancer.

    Full Text Available Abstract Background HIV-infected and HIV-exposed, uninfected infants experience a high burden of infectious morbidity and mortality. Hospitalization is an important metric for morbidity and is associated with high mortality, yet, little is known about rates and causes of hospitalization among these infants in the first 12 months of life. Methods Using data from a prevention of mother-to-child transmission (PMTCT trial (India SWEN, where HIV-exposed breastfed infants were given extended nevirapine, we measured 12-month infant all-cause and cause-specific hospitalization rates and hospitalization risk factors. Results Among 737 HIV-exposed Indian infants, 93 (13% were HIV-infected, 15 (16% were on HAART, and 260 (35% were hospitalized 381 times by 12 months of life. Fifty-six percent of the hospitalizations were attributed to infections; gastroenteritis was most common accounting for 31% of infectious hospitalizations. Gastrointestinal-related hospitalizations steadily increased over time, peaking around 9 months. The 12-month all-cause hospitalization, gastroenteritis-related hospitalization, and in-hospital mortality rates were 906/1000 PY, 229/1000 PY, and 35/1000 PY respectively among HIV-infected infants and 497/1000 PY, 107/1000 PY, and 3/1000 PY respectively among HIV-exposed, uninfected infants. Advanced maternal age, infant HIV infection, gestational age, and male sex were associated with higher all-cause hospitalization risk while shorter duration of breastfeeding and abrupt weaning were associated with gastroenteritis-related hospitalization. Conclusions HIV-exposed Indian infants experience high rates of all-cause and infectious hospitalization (particularly gastroenteritis and in-hospital mortality. HIV-infected infants are nearly 2-fold more likely to experience hospitalization and 10-fold more likely to die compared to HIV-exposed, uninfected infants.

    Background Morbidity and mortality of advanced human immunodeficiency virus infection (HIV) have declined in Western industrialized countries since the availability of highly active antiretroviral therapy (HAART). It is unclear if this has also happened in Hong Kong.Methods We studied a retrospective cohort of patients with advanced HIV disease in Hong Kong, China. First, the mortality of advanced HIV disease per year was calculated for the decade 1993 to 2002, both annually and according to patient observation before and after 1997. Second, the event rates were estimated for the clinical end points of acquired immune deficiency syndrome (AIDS) and death. Univariate and multivariate analyses were then performed to identify associated factors. Results The crude mortality of advanced HIV disease declined from 10.8-30.4 per 100 patients during 1993-1996, to 0.8-6.9 per 100 patients during 1997-2002. A rate ratio of 4.04 (95% CI, 2.52-6.47) was evident for those observed in 1993-1996, compared to those in 1997-2002. In a multivariate analysis where calendar period was adjusted, use of highly active antiretroviral therapy was associated with rate ratios of 0.13 (95% CI, 0.05-0.33) for death after AIDS, 0.08 (95% CI, 0.04-0.19) for AIDS after a CD4 cell count <200/μl, and 0.21 (95% CI, 0.07-0.67) for death after CD4 cell count <200/μl. In the same analysis, calendar period ceased to be a significant factor after adjustment for use of HAART.Conclusions The mortality and morbidity of advanced human immunodeficiency virus disease have declined in Hong Kong. This improved prognosis was attributable to the use of highly active antiretroviral therapy.

    2011-01-01

    Full Text Available Abstract Background Depression, cardiovascular disease (CVD risk factors and cognitive impairment are important causes of disability and poor health outcomes. In combination they lead to an even worse prognosis. Internet or web-based interventions have been shown to deliver efficacious psychological intervention programs for depression on a large scale, yet no published studies have evaluated their impact among patients with co-existing physical conditions. The aims of this randomised controlled trial are to determine the effects of an evidence-based internet intervention program for depression on depressive mood symptoms, cognitive function and treatment adherence in patients at risk of CVD. Methods/Design This study is an internet-based, double-blind, parallel group randomised controlled trial. The trial will compare the effectiveness of online cognitive behavioural therapy with an online attention control placebo. The trial will consist of a 12-week intervention phase with a 40-week follow-up. It will be conducted in urban and rural New South Wales, Australia and will recruit a community-based sample of adults aged 45 to 75 years. Recruitment, intervention, cognitive testing and follow-up data collection will all be internet-based and automated. The primary outcome is a change in severity of depressive symptoms from baseline to three-months. Secondary outcomes are changes in cognitive function and adherence to treatment for CVD from baseline to three, six and 12-months. Discussion Prior studies of depression amongst patients with CVD have targeted those with previous vascular events and major depression. The potential for intervening earlier in these disease states appears to have significant potential and has yet to be tested. Scalable psychological programs using web-based interventions could deliver care to large numbers in a cost effective way if efficacy were proved. This study will determine the effects of a web-based intervention on

    The consumption of high levels of saturated fat over the course of several weeks may lead to exaggerated cardiovascular reactivity. The consumption of a single high-fat meal has been associated with a transient impairment of vascular function. In a randomized, repeated measures, crossover study we tested whether the consumption of a single high-fat meal by healthy, normotensive participants would affect cardiovascular reactivity when compared with an isocaloric, low-fat meal. Thirty healthy participants ate a high-fat (42 g) and a low-fat (1 g) meal on 2 separate occasions, and their cardiovascular response to 2 standard laboratory stressors was measured. Systolic blood pressure, diastolic blood pressure, and total peripheral resistance were greater in participants following the consumption of the high-fat meal relative to the low-fat meal. The findings of the present study are consistent with the hypothesis that even a single high-fat meal may be associated with heightened cardiovascular reactivity to stress and offer insight into the pathways through which a high-fat diet may affect cardiovascular function.

    30% of the world population is diagnosed with metabolic syndrome. High fat/high sucrose diet (HF/HS, Western diet) correlates with metabolic syndrome prevalence. We characterized effects of the HF/HS diet on vascular (arterial stiffness, vasoreactivity, coronary collateral development) and cardiac (echocardiography) function, oxidative stress and inflammation in a rat model of metabolic syndrome (JCR). Furthermore, we determined whether male vs. female animals were affected differentially by the Western diet. Cardiovascular function in JCR male rats was impaired vs. normal rats (SD). HF/HS diet compromised cardiovascular (dys)function in JCR but not in SD male rats. In contrast, cardiovascular function was minimally impaired in JCR females on normal chow. However, cardiovascular function in JCR females on the HF/HS diet deteriorated to levels comparable to JCR males on the HF/HS diet. Similarly, oxidative stress was markedly increased in male but not female JCR rats on normal chow, but was equally exacerbated by the HF/HS diet in male and female JCR rats. These results indicate that the Western diet enhances oxidative stress and cardiovascular dysfunction in metabolic syndrome and eliminates the protective effect of female sex on cardiovascular function, implying that both males and females with metabolic syndrome are at equal risk for cardiovascular disease.

    Full Text Available BACKGROUND: Malariometric parameters are often primary endpoints of efficacy trials of malaria vaccine candidates. This study aims to describe the epidemiology of malaria prior to the conduct of a series of drug and vaccine trials in a rural area of Burkina Faso. METHODS: Malaria incidence was prospectively evaluated over one year follow-up among two cohorts of children aged 0-5 years living in the Saponé health district. The parents of 1089 children comprising a passive case detection cohort were encouraged to seek care from the local health clinic at any time their child felt sick. Among this cohort, 555 children were randomly selected for inclusion in an active surveillance sub-cohort evaluated for clinical malaria during twice weekly home visits. Malaria prevalence was evaluated by cross-sectional survey during the low and high transmission seasons. RESULTS: Number of episodes per child ranged from 0 to 6 per year. Cumulative incidence was 67.4% in the passive and 86.2% in the active cohort and was highest among children 0-1 years. Clinical malaria prevalence was 9.8% in the low and 13.0% in the high season (p>0.05. Median days to first malaria episode ranged from 187 (95% CI 180-193 among children 0-1 years to 228 (95% CI 212, 242 among children 4-5 years. The alternative parasite thresholds for the malaria case definition that achieved optimal sensitivity and specificity (70-80% were 3150 parasites/µl in the high and 1350 parasites/µl in the low season. CONCLUSION: Clinical malaria burden was highest among the youngest age group children, who may represent the most appropriate target population for malaria vaccine candidate development. The pyrogenic threshold of parasitaemia varied markedly by season, suggesting a value for alternative parasitaemia levels in the malaria case defintion. Regional epidemiology of malaria described, Sapone area field centers are positioned for future conduct of malaria vaccine trials.

    Adrenal adenomas are benign tumors often discovered incidentally, and >70% are hormonally inactive. The remaining subset may produce excess aldosterone, cortisol, or catecholamine. Perioperative outcomes after adrenalectomy for such "hormonally active" tumors remain unclear. This study examines in-hospital outcomes after unilateral adrenalectomy for hormonally active tumors. A retrospective review was performed using the Nationwide Inpatient Sample (2006-2011) to identify patients undergoing unilateral adrenalectomy for hormonally active or inactive tumors. Malignant adrenal tumors were excluded. Demographics, comorbidities, and postoperative complications were evaluated by univariate analysis, using two-tailed Chi-square and t-tests and multivariate logistic regression. Of 27,312 patients who underwent adrenalectomy, 78% (n = 21,279) had hormonally inactive and 22% (n = 6033) had hormonally active adrenal tumors. Among the latter, 65% (n = 4000) had primary hyperaldosteronism (Conn's syndrome), 33% (n = 1996) had hypercortisolism (Cushing's syndrome), and 1.4% (n = 85) had pheochromocytoma. Patients with pheochromocytoma had higher rate of comorbidities including congestive heart failure, chronic lung disease, and malignant hypertension compared with remaining hormonally active tumors (12% versus 4%, 18% versus 11%, 6% versus 2%; P pheochromocytoma versus other hormonally active tumors, mean length of stay was 5 versus 3 d and total in-hospital cost was $50,000 versus $41,000 (P pheochromocytoma had an independently higher risk for intraoperative blood transfusion (4.2, 95% confidence interval [CI] 2.4-7.2), postoperative cardiac (7.6, 95% CI 2.8-20.2), and respiratory (1.9, 95% CI 1.0-3.3) complications. Patients with pheochromocytoma have high rates of preoperative comorbidities, postoperative cardiopulmonary complications, and longer and more costly hospitalizations.

    The neutrophil-to-lymphocyte ratio (NLR) is a novel simple biomarker of inflammation. It has emerged as a predictor of poor prognosis in cancer and cardiovascular disease in general population. But little was known of its prognostic value in chronic hemodialysis (HD) patients. Here we investigated the association between NLR and cardiovascular risk markers, including increased pulse pressure (PP), left ventricular mass index (LVMI) and intima-media thickness (IMT), and mortality in HD patients. Two hundred and sixty-eight HD patients were enrolled in this study and were followed for 36 months. The primary end point was all-cause mortality and cardiovascular mortality. Multivariable Cox regression was used to calculate the adjusted hazard ratios for NLR on all-cause and cardiovascular survival. We pinpointed that higher NLR in HD patients was a predictor of increased PP, LVMI, and IMT; HD patients with higher NLR had a lower survival at the end of the study; furthermore, high NLR was an independent predictor of all-cause and cardiovascular mortality when adjusted for other risk factors. In conclusion, higher NLR in HD patients was associated with cardiovascular risk factors and mortality.

    The aging of the population and improvements in outcomes after cardiovascular surgery have resulted in a worldwide growing demand of complex surgical intervention for elderly patients. We briefly review the up-to-date English-language literature with particular focus on cardiovascular surgery in elderly patients. With earlier referral, careful preoperative evaluation, strategic planning, and the continuing efforts in optimizing surgical techniques, operative mortality and morbidity following primary or reoperative coronary artery bypass grafting and valvular interventions are expected to fall in this high-risk patient subset. Importantly,accumulating evidence indicates that elderly patients may benefit from improved functional status and quality of life after cardiovascular surgical therapy

    Animal models of acquired epilepsies aim to provide researchers with tools for use in understanding the processes underlying the acquisition, development and establishment of the disorder. Typically, following a systemic or local insult, vulnerable brain regions undergo a process leading to the development, over time, of spontaneous recurrent seizures. Many such models make use of a period of intense seizure activity or status epilepticus, and this may be associated with high mortality and/or global damage to large areas of the brain. These undesirable elements have driven improvements in the design of chronic epilepsy models, for example the lithium-pilocarpine epileptogenesis model. Here, we present an optimised model of chronic epilepsy that reduces mortality to 1% whilst retaining features of high epileptogenicity and development of spontaneous seizures. Using local field potential recordings from hippocampus in vitro as a probe, we show that the model does not result in significant loss of neuronal network function in area CA3 and, instead, subtle alterations in network dynamics appear during a process of epileptogenesis, which eventually leads to a chronic seizure state. The model’s features of very low mortality and high morbidity in the absence of global neuronal damage offer the chance to explore the processes underlying epileptogenesis in detail, in a population of animals not defined by their resistance to seizures, whilst acknowledging and being driven by the 3Rs (Replacement, Refinement and Reduction of animal use in scientific procedures) principles.

Atherosclerosis and generation of reactive oxygen species through oxidative stress is the major risk factor for cardiovascular disease. Atherothrombosis with low levels of high-density lipoprotein (HDL and high levels of low-density lipoprotein is a major risk factor for atherosclerosis-induced cardiovascular disease. Lipid-lowering drugs like statins, niacin, fibrates, and some newer agents, ie, the apolipoprotein A-I mimetics and the cholesteryl ester transfer protein inhibitors, not only increase HDL levels but are also effective in reducing key atherogenic lipid components, including triglyceride-rich lipoproteins. The aim of this review is to discuss the accumulating evidence suggesting that HDL possesses a diverse range of biological actions, and that increasing HDL levels by drug treatment may be beneficial in the prevention of cardiovascular disease.Keywords: cardiovascular disease, lipoproteins, statins, apolipoprotein, atherosclerosis

    Full Text Available Background: The development of strategies to reduce the prevalence of high blood pressure is an important challenge for all countries, populations, and governments. For this reason, the search of method in the prediction of the high blood pressure is an appropriate way, and a very important objective to get. Objetive: This study expects to show that cardiovascular hyperreactivity determined by the sustained weight test is a predictor of the high blood pressure independently from other cardiovascular risk factors. Methods: A five year cohort study was carried out (from 1998 to 2003 in which two groups were created. The 1st one with CHR (n = 41 and the 2nd one with (n= 127 of cardiovascular normoreactivity (CNR. Variables such as cardiovascular hyperreactivity high blood pressure, obesity, family history of high blood pressure, body mass index rate, smoking habit, salt consumption and alcohol consumption. An evaluation of the HBP risk was performed in each group, and the values of incidence of high blood pressure in each of them were compared. The chi square test was used as a statistic method. The stratified analysis and the determination of relative risk with a confidence interval of the 95 percent. The statistical significance was 95%. Results: The incidence of hypertension in the cohort of HRC was of 34,15/100 people and in the CNR of 10,24/100 people chi square = 13,3 GL= 1 P= 0,007, on the other hand, when we made adjustments according to different cardiovascular risk markers to determine the relationship between hypertension and hyperreactivity, it was observed that the relationship exists in spite of the risk marks mentioned before. Conclusions: The individuals whit HRC determined by the SWT have a risk to develop higher significant sustained hypertension then the cardiovascular normorreactivos ones this is an evidence that this method is useful to predict HBP.

    Obesity is a complex disease that results from increased energy intake and decreased energy expenditure. The gastrointestinal system plays a key role in the pathogenesis of obesity and facilitates caloric imbalance. Changes in gastrointestinal hormones and the inhibition of mechanisms that curtail caloric intake result in weight gain. It is not clear if the gastrointestinal role in obesity is a cause or an effect of this disease. Obesity is often associated with type 2 diabetes mellitus (T2DM) and cardiovascular diseases (CVD). Obesity is also associated with gastrointestinal disorders, which are more frequent and present earlier than T2DM and CVD. Diseases such as gastro-esophageal reflux disease, cholelithiasis or non-alcoholic steatohepatitis are directly related to body weight and abdominal adiposity. Our objective is to assess the role of each gastrointestinal organ in obesity and the gastrointestinal morbidity resulting in those organs from effects of obesity. PMID:24602085

Patients will be preoccupied with their partner’s perceived lack of sexual fidelity and will often behave in an unacceptable or extreme way as they endeavor to prove their ideas. Misuse of any psychomotor is an important association cause morbidity jealousy agents, like CNS stimulants that release the catecholamine, particularly dopamine, from pre synaptic terminals substance should be treated as a priority. Where higher levels of violence are reported Sildenafil may be useful as a diagnostic as well as therapeutic test in such cases .Many studies have shown an association between high alcohol consumption and developing morbid jealousy. Amphetamine-induced psychosis has been extensively studied because of its close resemblance to schizophrenia.

    Low circulating high-molecular-weight (HMW) adiponectin might be associated with increased cardiovascular risk. This study aimed to investigate the relationship between HMW adiponectin and cardiovascular events in patients with type 2 diabetes mellitus (T2DM) with an adverse cardiovascular risk profile. The investigation took place in a specialized outpatient clinic for metabolic diseases and included 147 patients with T2DM following a cross-sectional and a prospective study protocol. Ninety patients had macrovascular disease at baseline defined as preexisting coronary artery disease, previous stroke, or peripheral artery disease. HMW adiponectin measured by enzyme-linked immunosorbent assay (Fujirebio, Tokyo, Japan) and routine clinical parameters were determined in all patients at baseline. The occurrence of new cardiovascular events (myocardial infarction, stroke, and all-cause mortality) during the follow-up period was evaluated. No significant correlations between traditional cardiovascular risk markers and HMW adiponectin could be detected. HMW adiponectin did not differ between subjects with and without macrovascular disease at baseline (3.5 [interquartile range [IQR]: 2.2-5.7] mg/L vs 4.0 [IQR: 2.5-7.1] mg/L). During a follow-up of 19.3 (IQR: 16-25) months, 61 endpoints (41 myocardial infarctions, 10 strokes, and 10 deaths) were observed. A 1-standard-deviation increment of log-transformed HMW adiponectin was not significantly associated with the occurrence of cardiovascular events (Adjusted hazard ratio [HR]: 0.95; 95% confidence interval [CI]: 0.58-1.54; P = 0.835). In conclusion, HMW adiponectin was not related to present macrovascular disease and is not associated with future cardiovascular events in high-risk patients with T2DM. It is unlikely that HMW adiponectin has significant vasoprotective effects in these patients.

    The prevalence of obesity is increasing in the United States and worldwide, bringing with it an excess of morbidity and premature death. Obesity is strongly associated with both traditional cardiovascular risk factors as well as direct effects on hemodynamics and cardiovascular structure and function. In fact, cardiovascular disease is one of the major causes of morbidity and mortality in obese patients. Often, lifestyle and pharmacological weight-loss interventions are of limited efficacy in severely obese patients. Bariatric surgery has been shown to be a feasible option to achieve substantial and sustained weight loss in this group of patients. It is a safe procedure with low in-hospital and 30-day mortality rates even in groups that are considered higher risk for surgery (e.g., the elderly), especially if performed in high-volume centers. There is observational evidence that bariatric surgery in severely obese patients is associated with both a reduction of traditional cardiovascular risk factors as well as improvement in cardiac structure and function. Marked decreases in the levels of inflammatory and prothrombotic markers, as well as markers of subclinical atherosclerosis and endothelial dysfunction, are seen after bariatric surgery. This article summarizes the existing evidence regarding the cardiovascular benefits in patients following bariatric surgery.

    Morbid obesity is a chronic multifunctional disease characterized by an accumulation of fat. Epidemiological studies have shown that obesity is associated with cardiovascular and metabolic disorders. Endothelial dysfunction, as defined by an imbalance between relaxing and contractile endothelial factors, plays a central role in the pathogenesis of these cardiometabolic diseases. Diminished bioavailability of nitric oxide (NO) contributes to endothelial dysfunction and impairs endothelium- dependent vasodilatation. But this is not the only mechanism that drives to endothelial dysfunction. Obesity has been associated with a chronic inflammatory process, atherosclerosis, and oxidative stress. Moreover levels of asymmetrical dimethyl-L-arginine (ADMA), an endogenous inhibitor of endothelial nitric oxide synthase (eNOS), are elevated in obesity. On the other hand, increasing prostanoid-dependent vasoconstriction and decreasing vasodilator prostanoids also lead to endothelial dysfunction in obesity. Other mechanisms related to endothelin-1 (ET-1) or endothelium derived hyperpolarizing factor (EDHF) have been proposed. Bariatric surgery (BS) is a safe and effective means to achieve significant weight loss, but its use is limited only to patients with severe obesity including morbid obesity. BS also proved efficient in endothelial dysfunction reduction improving cardiovascular and metabolic comorbidities associated with morbid obesity such as diabetes, coronary artery disease, nonalcoholic fatty liver disease and cancer. This review will provide a brief overview of the mechanisms that link obesity with endothelial dysfunction, and how weight loss is a cornerstone treatment for cardiovascular comorbidities obesity-related. A better understanding of the mechanisms of obesity-induced endothelial dysfunction may help develop new therapeutic strategies to reduce cardiovascular morbidity and mortality.

    The relation between dietary magnesium intake and cardiovascular disease (CVD) or mortality was evaluated in several prospective studies, but few of them have assessed the risk of all-cause mortality, which has never been evaluated in Mediterranean adults at high cardiovascular risk. The aim of this study was to assess the association between magnesium intake and CVD and mortality risk in a Mediterranean population at high cardiovascular risk with high average magnesium intake. The present study included 7216 men and women aged 55-80 y from the PREDIMED (Prevención con Dieta Mediterránea) study, a randomized clinical trial. Participants were assigned to 1 of 2 Mediterranean diets (supplemented with nuts or olive oil) or to a control diet (advice on a low-fat diet). Mortality was ascertained by linkage to the National Death Index and medical records. We fitted multivariable-adjusted Cox regressions to assess associations between baseline energy-adjusted tertiles of magnesium intake and relative risk of CVD and mortality. Multivariable analyses with generalized estimating equation models were used to assess the associations between yearly repeated measurements of magnesium intake and mortality. After a median follow-up of 4.8 y, 323 total deaths, 81 cardiovascular deaths, 130 cancer deaths, and 277 cardiovascular events occurred. Energy-adjusted baseline magnesium intake was inversely associated with cardiovascular, cancer, and all-cause mortality. Compared with lower consumers, individuals in the highest tertile of magnesium intake had a 34% reduction in mortality risk (HR: 0.66; 95% CI: 0.45, 0.95; P magnesium intake was inversely associated with mortality risk in Mediterranean individuals at high risk of CVD. This trial was registered at controlled-trials.com as ISRCTN35739639.

    Full Text Available BACKGROUND: In schistosomiasis control programmes using mass chemotherapy, epidemiological and morbidity aspects of the disease need to be studied so as to monitor the impact of treatment, and make recommendations accordingly. These aspects were examined in the community of Musoli village along Lake Victoria in Mayuge district, highly endemic for Schistosoma mansoni infection. METHODOLOGY AND PRINCIPAL FINDINGS: A cross sectional descriptive study was undertaken in a randomly selected sample of 217 females and 229 males, with a mean age of 26 years (SD ± 16, range 7-76 years. The prevalence of S. mansoni was 88.6% (95% CI: 85.6-91.5. The geometric mean intensity (GMI of S. mansoni was 236.2 (95% CI: 198.5-460.9 eggs per gram (epg faeces. Males had significantly higher GMI (370.2 epg than females (132.6 epg and age was also significantly associated with intensity of infection. Levels of water contact activities significantly influenced intensity of infection and the highest intensity of infection was found among people involved in fishing. However, organomegaly was not significantly associated with S. mansoni except for very heavy infection (>2000 epg. Liver image patterns C and D indicative of fibrosis were found in only 2.2% and 0.2%, respectively. S. mansoni intensity of infection was associated with portal vein dilation and abnormal spleen length. Anaemia was observed in 36.4% of the participants but it was not associated with S. mansoni infection intensity. Considering growth in children as one of the morbidity indicators of schistosomiasis, intensity of S. mansoni was significantly associated with stunting. CONCLUSION: Although organ-related morbidity, with the exception of periportal fibrosis, and S. mansoni infections were highly prevalent, the two were only associated for individuals with very high infection intensities. These results contrast starkly with reports from Ugandan Lake Albert fishing communities in which periportal fibrosis

    Full Text Available Tocotrienols have been reported to improve lipid profiles, reduce atherosclerotic lesions, decrease blood glucose and glycated haemoglobin concentrations, normalise blood pressure in vivo and inhibit adipogenesis in vitro, yet their role in the metabolic syndrome has not been investigated. In this study, we investigated the effects of palm tocotrienol-rich fraction (TRF on high carbohydrate, high fat diet-induced metabolic, cardiovascular and liver dysfunction in rats. Rats fed a high carbohydrate, high fat diet for 16 weeks developed abdominal obesity, hypertension, impaired glucose and insulin tolerance with increased ventricular stiffness, lower systolic function and reduced liver function. TRF treatment improved ventricular function, attenuated cardiac stiffness and hypertension, and improved glucose and insulin tolerance, with reduced left ventricular collagen deposition and inflammatory cell infiltration. TRF improved liver structure and function with reduced plasma liver enzymes, inflammatory cell infiltration, fat vacuoles and balloon hepatocytes. TRF reduced plasma free fatty acid and triglyceride concentrations but only omental fat deposition was decreased in the abdomen. These results suggest that tocotrienols protect the heart and liver, and improve plasma glucose and lipid profiles with minimal changes in abdominal obesity in this model of human metabolic syndrome.

    To evaluate and compare the feto-maternal outcomes of pregnant women with potentially life-threatening complications (PLTC) and near miss events admitted to the obstetric high dependency units (OHDU). Pregnant women with PLTC admitted to the OHDU were enrolled. Feto-maternal outcomes, need for NICU admission and neonatal mortality, were compared between women without near miss events (controls) and those with near miss events. Of the 1505 admissions to the obstetric department during the study period, 1127 delivered at our hospital. Among the deliveries 125 (11%) women were admitted to the OHDU and 19 (15%) of them were referred to the intensive care unit (ICU) of the hospital. The incidence of near miss morbidity (n = 46) was 37% among the mothers admitted to OHDU and 4.1% among the deliveries. The outcomes were similar in both groups for mean birth weight (among live births), neonatal death and still birth or intra-uterine deaths. The mean duration of ICU stay, proportion of ICU admission, and the mean duration of hospital stay were significantly higher for women with near miss events. In the presence of standardized OHDU and an ICU, the feto-maternal outcomes of women with PLTC and near miss event are similar to those without near miss events.

    Cardiovascular diseases are the most common cause of death in western countries. Understanding the rupture of vulnerable atherosclerotic plaques and monitoring the effect of innovative therapies of heart failure is of fundamental importance. A flexible, high resolution, high sensitivity detector system for molecular imaging with radionuclides on small animal models has been designed for this aim. A prototype has been built using tungsten pinhole and LaBr3(Ce) scintillator coupled to Hamamatsu Flat Panel PMTs. Compact individual-channel readout has been designed, built and tested. Measurements with phantoms as well as pilot studies on mice have been performed, the results show that the myocardial perfusion in mice can be determined with sufficient precision. The detector will be improved replacing the Hamamatsu Flat Panel with Silicon Photomultipliers (SiPMs) to allow integration of the system with MRI scanners. Application of LaBr3(Ce) scintillator coupled to photosensor with high photon detection efficiency and excellent energy resolution will allow dual-label imaging to monitor simultaneously the cardiac perfusion and the molecular targets under investigation during the heart therapy.

    Plasma levels of high-density lipoprotein (HDL) are strongly and inversely correlated with atherosclerotic cardiovascular diseases. However, it is becoming clear that a functional HDL is a more desirable target than simply increasing HDL-cholesterol levels. The best known antiatherogenic function of HDL particles relates to their ability to promote reverse cholesterol transport from peripheral cells. However, HDL also possesses antioxidant, anti-inflammatory, and antithrombotic effects. This review focuses on the state of knowledge regarding assays of HDL heterogeneity and function and their relationship to cardiovascular diseases. Copyright © 2012 National Lipid Association.

    Although moderate-intensity continuous training (MICT) has been the traditional model for aerobic exercise training for over four decades, a growing body of literature has demonstrated equal if not greater improvement in aerobic capacity and similar beneficial effects on body composition, glucose metabolism, blood pressure, and quality of life from high-intensity interval training (HIIT). An advantage of HIIT over MICT is the shorter time required to perform the same amount of energy expenditure. The current brief review summarizes the effects of HIIT on peak aerobic capacity and cardiovascular risk factors in healthy adults and those with various cardiovascular diseases, including coronary artery disease, chronic heart failure, and post heart transplantation.

    2013-01-01

    Full Text Available The prevalence of Type 2 diabetes mellitus (T2DM has increased; as a result the number of patients with T2DM undergoing surgical procedures has also increased. This population is at high risk of macrovascular (cardiovascular disease, peripheral vascular disease or microvascular (retinopathy, nephropathy or neuropathy complications, both increasing their perioperative morbidity and mortality. Diabetes patients are more at risk of poor wound healing, respiratory infection, myocardial infarction, admission to intensive care, and increased hospital length of stay. This leads to increased inpatient costs. The outcome of perioperative glycaemia management remains a significant clinical problem without a universally accepted solution. The majority of evidence on morbidity and mortality of T2DM patients undergoing surgery comes from the setting of cardiac surgery; there was less evidence on non-cardiac surgery and bariatric surgery. Bariatric surgery is increasingly performed in patients with severe obesity complicated by T2DM, but is distinguished from general surgery as it immediately improves the glucose homeostasis postoperatively. The improvements in glycaemia are thought to be independent of weight loss and this requires different postoperative management. Patients usually have to follow specific preoperative diets which lead to improvement in glycaemia immediately before surgery. Here we review the available data on the mortality and morbidity of patients with T2DM who underwent elective surgery (cardiac, non-cardiac and bariatric surgery and the current knowledge of the impact that preoperative, intraoperative and postoperative glycaemic management has on operative outcomes.

    Hypertension and depression are both important risk factors for cardiovascular diseases. Nevertheless, the association of blood pressure on and depression has not been completely established. This study aims to analyze whether depression may influence the control of blood pressure in hypertensive individuals at high cardiovascular risk. Cross-sectional study, embedded within the PREDIMED clinical trial, of 5954 hypertensive patients with high cardiovascular risk factor profiles. The relationship between blood pressure control and depression was analyzed. A multivariate analysis (logistic and log-linear regression), adjusting for potential confounders (socio-demographic factors, body mass index, lifestyle, diabetes, dyslipidemia, and antihypertensive treatment), was performed. Depressive patients, with and without antidepressant treatment, had better blood pressure control (OR: 1.28, CI 95%: 1.06-1.55, and OR: 1.30, CI 95%: 1.03-1.65, respectively) than non-depressive ones. Regarding blood pressure levels, systolic blood pressure values (mmHg) were found to be lower in both treated and untreated depressive patients (Log coefficient Beta: -1.59, 95% CI: -0.50 to -2.69 and Log coefficient Beta: -3.49, 95% CI: -2.10 to -4.87, respectively). Among hypertensive patients at high cardiovascular risk, the control of blood pressure was better in those diagnosed with depression. Unique identifier: ISRCTN35739639.

    Full Text Available Background: Bipolar disorder is a relatively common, long-term, and disabling psychiatric illness that is associated with high levels of functional impairment, morbidity, mortality, and an increased risk of suicide. Psychiatric co-morbidity in bipolar disorder ranges from 57.3% to 74.3%, whereas medical co-morbidity varies from 2.7-70%. Indian scenario in this aspect is not clear. Materials and Methods: The objective was to ascertain the prevalence of physical and psychiatric co-morbidities in patients attending a tertiary care center over a period of 1 year and its relationship with socio-demographic and clinical variables. One hundred and twenty-five case record files were included in the review. OPCRIT software was used for re-establishing the diagnosis of bipolar disorder, which yielded 120 cases. A semi-structured pro-forma, specifically designed for the study, was used to collect the socio-demographic and clinical details. Results: Co-morbid psychiatric disorders were found in 52 (43.3% of the sample, whereas co-morbid physical illness was present in 77 (64.2% patients. The most common psychiatric disorder associated was substance use disorder (27.5%, whereas co-morbid cardiovascular disorder was the most frequent physical diagnosis in the sample (20%. Discussion: The prevalence of co-morbid psychiatric disorders in bipolar patients was lower than that reported in western literature. It could be related to retrospective nature of study or reflect true lower prevalence rates. Also, certain disorders such as eating disorders were absent in our sample, and migraine diagnosis was very infrequent.

  6. Advances in ultrasound methods for high-resolution imaging of the cardiovascular system.

    Acoustic microscopy entails the use of high-frequency high-resolution ultrasound methods to produce images of sound waves reflected from or propagated through some tissue of interest. The image contrast depends on microscopic differences in the intrinsic material properties of the substance imaged, such as mass density or compressibility. Pathologic changes in cardiovascular tissues at the subcellular level can be observed with high-frequency acoustic imaging techniques, based on alterations in the structure, properties, and organization of cells and their surrounding matrix. Potential applications extend from delineation of cardiovascular development in experimental animals to clinical characterization of the composition of atherosclerotic lesions with intravascular ultrasound and estimation of the potential for plaque rupture and infarction.

    In the EMPA-REG OUTCOME trial (Empagliflozin Cardiovascular Outcome Event Trial in Type 2 Diabetes Mellitus Patients), empagliflozin added to standard of care in patients with type 2 diabetes mellitus and high cardiovascular risk reduced the risk of 3-point major adverse cardiovascular events, driven by a reduction in cardiovascular mortality, with no significant difference between empagliflozin and placebo in risk of myocardial infarction or stroke. In a modified intent-to-treat analysis, the hazard ratio for stroke was 1.18 (95% confidence interval, 0.89-1.56; P=0.26). We further investigated cerebrovascular events. Patients were randomized to empagliflozin 10 mg, empagliflozin 25 mg, or placebo; 7020 patients were treated. Median observation time was 3.1 years. The numeric difference in stroke between empagliflozin and placebo in the modified intent-to-treat analysis was primarily because of 18 patients in the empagliflozin group with a first event >90 days after last intake of study drug (versus 3 on placebo). In a sensitivity analysis based on events during treatment or ≤90 days after last dose of drug, the hazard ratio for stroke with empagliflozin versus placebo was 1.08 (95% confidence interval, 0.81-1.45; P=0.60). There were no differences in risk of recurrent, fatal, or disabling strokes, or transient ischemic attack, with empagliflozin versus placebo. Patients with the largest increases in hematocrit or largest decreases in systolic blood pressure did not have an increased risk of stroke. In patients with type 2 diabetes mellitus and high cardiovascular risk, there was no significant difference in the risk of cerebrovascular events with empagliflozin versus placebo.

    Full Text Available The study aimed at assessing the potential use of lower total and HMW adiponectin levels for predicting cardiovascular risk in patients with type 2 diabetes mellitus (T2DM. Concentrations of total adiponectin or high molecular weight (HMW adiponectin decrease in association with the development of metabolic dysfunction such as obesity, insulin resistance, or T2DM. Increased adiponectin levels are associated with a lower risk for coronary heart disease. A total of 551 individuals were assessed. The first group comprised metabolically healthy participants (143 females, and 126 males and the second group were T2DM patients (164 females, and 118 males. Both total adiponectin and HMW adiponectin in diabetic patients were significantly lower when compared with the group of metabolically healthy individuals. There was a weak monotonic correlation between HMW adiponectin levels and triglycerides levels. Binary logistic regression analysis, gender adjusted, showed a higher cardiovascular risk in diabetic persons when both total adiponectin (OR = 1.700 and HMW adiponectin (OR = 2.785 levels were decreased. A decrease in total adiponectin levels as well as a decrease in its HMW adiponectin is associated with a higher cardiovascular risk in individuals with T2DM. This association suggests that adiponectin levels may be potentially used as an epidemiological marker for cardiovascular risk in diabetic patients.

    This study analyzed morbidity, mortality and prognostic factors for patient survival in a single center collective of patients with colorectal cancer and a high follow-up rate. A total of 698 consecutive patients were included in this study. Data were collected prospectively. Descriptive and survival analyses as well as Cox regression analyses were performed to identify factors for morbidity, mortality and prognostic factors for survival. At presentation 78.8 % of the colon cancer patients and 83.5 % of rectal cancer patients showed symptomatic disease and 6.5 % of patients underwent an emergency procedure. Mortality was 3.6 %, morbidity was 42.7 % and 4.3 % of patients developed an anastomotic leakage with the need of reoperation. In spite of the regular application of a fast-track program, 10 % of patients had a prolonged duration of bowel paralysis. In patients with colon cancer there were no differences between overall survival (OAS) and disease-free survival, whereas there was a significant difference in patients with rectal cancer. The mean survival of all patients was 65.39 ± 1.722 months. The ASA score, cardiovascular disease, number of metastatic lymph nodes, lymph node ratio, residual tumor and general or surgery-associated complications were strongly independent influencing factors on OAS. A Cox analysis revealed age at diagnosis and microscopic residual tumor (TNM R1) as highly significant influencing factors on OAS. Other significant factors of influence on OAS were development of general or surgery-associated complications and the presence of cardiovascular diseases. Cardiovascular disease leads to a higher morbidity rate whereas age, International Union Against Cancer (UICC) stage, R-status, lymphatic spread and occurrence of complications are important prognostic factors for survival.

    Dyslipidemia results from consumption of a diet rich in saturated fatty acids and is usually associated with cardiovascular disease. A diet rich in unsaturated fatty acids is usually associated with improved cardiovascular condition. To investigate whether a high-fat diet rich in unsaturated fatty acids (U-HFD) - in which fatty acid represents approximately 45% of the total calories - impairs the cardiovascular system. Male, 30-day-old Wistar rats were fed a standard (control) diet or a U-HFD containing 83% unsaturated fatty acid for 19 weeks. The in vivo electrocardiogram, the spectral analysis of heart rate variability, and the vascular reactivity responses to phenylephrine, acetylcholine, noradrenaline and prazosin in aortic ring preparations were analyzed to assess the cardiovascular parameters. After 19 weeks, the U-HFD rats had increased total body fat, baseline glucose levels and feed efficiency compared with control rats. However, the final body weight, systolic blood pressure, area under the curve for glucose, calorie intake and heart weight⁄final body weight ratio were similar between the groups. In addition, both groups demonstrated no alteration in the electrocardiogram or cardiac sympathetic parameters. There was no difference in the responses to acetylcholine or the maximal contractile response of the thoracic aorta to phenylephrine between groups, but the concentration necessary to produce 50% of maximal response showed a decrease in the sensitivity to phenylephrine in U-HFD rats. The cumulative concentration- effect curve for noradrenaline in the presence of prazosin was shifted similarly in both groups. The present work shows that U-HFD did not impair the cardiovascular parameters analyzed.

    Metabolic syndrome (MS) is associated with subsequent appearance of diabetes and cardiovascular disease. As compared to other Spanish regions, Murcia (southern Spain) registers increased obesity as well as cardiovascular morbidity and mortality. The aim of this study was to assess the prevalence of MS and its components, awareness of obesity as a health risk and associated lifestyles. A population-based, cross-sectional study was conducted in 2003, covering a sample of 1555 individuals 20 years and over. MS was defined according to the Revised National Cholesterol Education Program Adult Treatment Panel III (R-ATPIII), International Diabetes Federation (IDF) and Joint Interim Statement (JIS) criteria. Both low (94/80) and high (102/88) waist circumference (WC) thresholds were considered. Prevalence of MS was 27.2% (95%CI: 25.2-29.2), 32.2% (95%CI: 30.1-34.3) and 33.2% (95%CI: 31.2-35.3) according to the R-ATPIII, IDF and JIS94/80 respectively. It increased with age until reaching 52.6% (R-ATPIII) or 60.3% (JIS94/80) among persons aged 70 years and over, and was higher in persons with little or no formal education (51.7% R-ATPIII, 57.3% JIS94/80). The most common risk factors were hypertension (46.6%) and central obesity (40.7% and 66.1% according to high and low WC cut-off points respectively). Although most persons were aware that obesity increased health risks, regular exercise was very unusual (13.0% centrally obese, 27.2% non-centrally obese). Adherence to dietary recommendations was similar among centrally obese and non-centrally obese subjects. Prevalence of MS is high in our population, is comparable to that found in northern Europe and varies with the definition used. Adherence to preventive recommendations and to adequate weight promotion is very low. In the absence of a specific treatment for MS, integrated intervention based on a sustained increase in physical activity and changes in diet should be reinforced.

    Full Text Available Abstract To evaluate the relationship of obesity, cognitive impairment and depressive symptoms in patients with high cardiovascular risk. Methods: A sample of 93 patients aged 50 years or older was selected from the Center of Dyslipidemia and High Cardiovascular Risk from Hospital de Clínicas de Porto Alegre (HCPA. Patients with stroke were excluded. For cognitive evaluation, the MMSE (Mini Mental State Examination was used. A score of 24 or less was considered as cognitive impairment, and for those who had 4 years or less of education, the cutoff point was 17. The GDS-15 (Geriatric Depression Scale was also used, with the cutoff of 6 for presence of depressive symptoms. Results: Obese patients showed lower mean MMSE scores compared to non-obese patients (p=0.0012. Additionally, for every one point increase in BMI above 30 there was a 27% increase in the chances of the patient having cognitive impairment. The obese patients presented 31% chance of having cognitive impairment compared with overweight subjects. Conclusions: Our findings corroborated the association between obesity and cognitive impairment in high cardiovascular risk patients. This association however, was not observed for depressive symptoms.

    We assessed the relationship between the level of high-sensitivity C-reactive protein (hsCRP) and cardiovascular risk factors in Korean adults. We reviewed 1,561 patients with cardiovascular disease or diabetes mellitus with hsCRP levels measured within the past year. Four cardiovascular risk groups were determined: low (risk), moderate (2 risk), high (10-20%) and very high (>20%) risk, according to the number of risk factors and the Framingham/NCEP ATP III risk score. The correlations between the hsCRP level and cardiovascular risk factors (age, smoking, hypertension, lipid profiles and familial history of premature coronary heart disease) were investigated. The mean and median hsCRP (mg/L) levels were 1.32 ± 9.69 and 0.29 (range: 0.01-7.48), respectively. Men had a higher median level of hsCRP than women (plevels of hs CRP significantly increased from the low to the very high risk group (0.15, 0.23, 0.27 and 0.47, respectively) and were significantly correlated with age, the level of glycosylated hemoglobin, body mass index (BMI), the level of high-density lipoprotein cholesterol (HDL-C), the low-density lipoprotein cholesterol (LDL-C)/HDL-C ratio, the LDL-C/total cholesterol (TC) ratio, the HDL-C/TC ratio, the HDL-C/triglyceride (TG) ratio and the TC/TG ratio. Neither smoking, the LDL-C level nor the TG level affected the hsCRP level. In a multivariate regression analysis, age, the HDL-C level, the LDL-C/TC ratio and BMI were found to be independently correlated with the hsCRP level. There is a significant relationship between the degree of cardiovascular risk and the hsCRP level in Korean adults with cardiovascular disease or diabetes mellitus. Assessing the hsCRP levels may thus provide additive value in predicting cardiovascular risks.

    Depression increases the risk of adverse cardiac events. Cardiovascular reactivity is defined as the pattern of cardiovascular responses to mental stress. An altered pattern of cardiovascular reactivity is an indicator of subsequent cardiovascular disease. Because depression and adverse cardiac events may have a dose-dependent association, this study examined the differences in cardiovascular reactivity to mental stress between patients with major depressive disorder (MDD) with high depression levels and those with low depression levels. Moreover, autonomic nervous system regulation is a highly plausible biological mechanism for the pattern of cardiovascular reactivity to mental stress. The association between cardiovascular reactivity and parameters of heart rate variability (HRV), an index for quantifying autonomic nervous system activity modulation, was thus examined. This study included 88 patients with MDD. HRV was measured before stress induction. The Stroop Color and Word Test and mirror star-tracing task were used to induce mental stress. We observed no significant association between depressive symptom level and any of the cardiovascular reactivity parameters. Cardiovascular reactivity to mental stress was comparable between patients with MDD with high-level depressive symptoms and those with low-level depressive symptoms. After adjusting for confounding variables, the high-frequency domain of HRV was found to be an independent predictor of the magnitude of heart rate reactivity (β = -.33, p = .002). In conclusion, the magnitude of cardiovascular reactivity may be independent of depression severity in patients with MDD. The autonomic regulation of cardiovascular responses to mental stress primarily influences heart rate reactivity in patients with MDD.

    Although moderate-intensity continuous training (MICT) has been the traditional model for aerobic exercise training for over four decades, a growing body of literature has demonstrated equal if not greater improvement in aerobic capacity and similar beneficial effects on body composition, glucose metabolism, blood pressure, and quality of life from high-intensity interval training (HIIT). An advantage of HIIT over MICT is the shorter time required to perform the same amount of energy expenditure. The current brief review summarizes the effects of HIIT on peak aerobic capacity and cardiovascular risk factors in healthy adults and those with various cardiovascular diseases, including coronary artery disease, chronic heart failure, and post heart transplantation.

    Investigations were made at surgical treatment stages in 102 cancer patients (mean age 72 +/- 5.8 years) at high cardiovascular risk, who received continuous therapy that reduced heart rate and blood pressure, in order to compensate for the course of coronary heart disease and arterial hypertension. The time course of changes in the major circulatory and metabolic parameters was analyzed in patients during operations on the abdomen and small pelvis while using three different multimodal anesthetic techniques (general intravenous anesthesia-based diazepam, propofol, fentanyl, ketamine; sevofluorane-based inhalational; combined epidural and intravenous one). The advantages and limitations of the above methods were shown in patients on cardio- and vasotropic therapies. Correcting modes (transesophageal atrial pacing, morning-dose drug withdrawal) for its possible related bradycardiac and hypotensive disorders, which reduce a risk of perioperative cardiovascular complications, are set forth.

    Full Text Available Acute cardiovascular responses to different high-velocity resistance exercise protocols were compared in untrained older women. Twelve apparently healthy volunteers (62.6 ± 2.9 y performed three different protocols in the bench press (BP. All protocols involved three sets of 10 repetitions performed with a 10RM load and 2 minutes of rest between sets. The continuous protocol (CP involved ten repetitions with no pause between repetitions. The discontinuous protocols were performed with a pause of five (DP5 or 15 (DP15 seconds between the fifth and sixth repetitions. Heart rate (HR, systolic blood pressure (SBP, rate pressure product (RPP, Rating of Perceived Exertion (RPE, and blood lactate (BLa were assessed at baseline and at the end of all exercise sets. Factorial ANOVA was used to compare the cardiovascular response among different protocols. Compared to baseline, HR and RPP were significantly (p < 0.05 higher after the third set in all protocols. HR and RPP were significantly (p < 0.05 lower in DP5 and DP15 compared with CP for the BP exercise. Compared to baseline, RPE increased significantly (p < 0.05 with each subsequent set in all protocols. Blood lactate concentration during DP5 and DP15 was significantly lower than CP. It appears that discontinuous high-velocity resistance exercise has a lower cardiovascular demand than continuous resistance exercise in older women

    Full Text Available Abstract Background To determine if recommended treatment targets, as specified in clinical practice guidelines for the management of cardiovascular disease, reduces the risk of renal complications in high risk patient populations. Methods This was a cohort study. Participants in Utrecht, The Netherlands either at risk of, or had cardiovascular disease were recruited. Cardiovascular treatment targets were achievement of control in systolic and diastolic blood pressure, total and low-density cholesterol, and treatment of albuminuria. Outcome measures were time to development of end stage renal failure or symptomatic renal atherosclerotic disease requiring intervention. Results The cohort consisted of 7,208 participants; 1,759 diabetics and 4,859 with clinically manifest vascular disease. The median age was 57 years and 67% were male. Overall, 29% of the cohort achieved the treatment target for systolic blood pressure, 39% for diastolic blood pressure, 28% for total cholesterol, 31% for LDL cholesterol and 78% for albuminuria. The incidence rate for end stage renal failure and renal atherosclerotic disease reduced linearly with each additional treatment target achieved (p value less than 0.001. Achievement of any two treatment targets reduced the risk of renal complications, hazard ratio 0.46 (95% CI 0.26-0.82. For patients with clinically manifest vascular disease and diabetes, the hazard ratios were 0.56 (95% CI 0.28 - 1.12 and 0.28 (95%CI 0.10 - 0.79 respectively. Conclusion Clinical guidelines for cardiovascular disease management do reduce risk of renal complications in high risk patients. Benefits are seen with attainment of any two treatment targets.

    The continued high rate of cardiovascular morbidity and mortality has attracted wide concern and great attention of pharmaceutical industry. In order to reduce the attrition of cardiovascular drug R&D, it might be helpful recapitulating previous failures and identifying the potential factors to success. This perspective mainly analyses the 30 cardiovascular drugs dropped from clinical development in 2012. Reasons causing the termination of the cardiovascular drugs in the past 5 years are also tabulated and analysed. The analysis shows that the attrition is highest in Phase II trials and financial and strategic factors and lack of clinical efficacy are the principal reasons for these disappointments. To solve the four problems (The 'better than the Beatles' problem, the 'cautious regulator' problem, the 'throw money at it' tendency and the 'basic researchbrute force' bias) is recommended as the main measure to increase the number and quality of approvable products.

    Full Text Available Considering the high mortality and morbidity rate associated with cardiovascular diseases, Cardiacrehabilitation (CR is regarded for prevention and management of cardiovascular diseases. CR servicesare generally provided in an outpatient as comprehensive, long-term programs involving medicalevaluation, prescribed exercise, cardiac risk factor modification, education and counseling. This includesnutritional therapies, weight loss program management of lipid abnormalities with diet and medication,blood pressure control, diabetes management and stress management. The exercise component of a totalapproach to rehabilitation helps to overcome the fears and anxieties that so many people experience aftera heart attack. Aerobic exercise training program improves cardiovascular fitness in both healthyindividual and cardiac patients. Cardiac rehabilitation prevents and treat cardiovascular disease, reducescardiac risk factors, improving patient’s exercise capacity and enhancing quality of life. Aerobicexercise with intensity of approximately 60 to 70% of the maximal heart rate for 30 to 60 minutes, 3 to 4times a week, for 4 to 6 weeks enhances exercise capacity.

    Given the increasing focus on early mortality and readmission rates among patients with acute coronary syndrome (ACS), this study was designed to evaluate the accuracy of the GRACE risk score for identifying patients at high risk of 30-day post-discharge mortality and cardiovascular readmission. This was a retrospective study carried out in a single center with 4229 ACS patients discharged between 2004 and 2010. The study endpoint was the combination of 30-day post-discharge mortality and readmission due to reinfarction, heart failure or stroke. One hundred and fourteen patients had 30-day events: 0.7% mortality, 1% reinfarction, 1.3% heart failure, and 0.2% stroke. After multivariate analysis, the six-month GRACE risk score was associated with an increased risk of 30-day events (HR 1.03, 95% CI 1.02-1.04; p<0.001), demonstrating good discrimination (C-statistic: 0.79 ± 0.02) and optimal fit (Hosmer-Lemeshow p=0.83). The sensitivity and specificity were adequate (78.1% and 63.3%, respectively), and negative predictive value was excellent (99.1%). In separate analyses for each event of interest (all-cause mortality, reinfarction, heart failure and stroke), assessment of the six-month GRACE risk score also demonstrated good discrimination and fit, as well as adequate predictive values. The six-month GRACE risk score is a useful tool to predict 30-day post-discharge death and early cardiovascular readmission. Clinicians may find it simple to use with the online and mobile app score calculator and applicable to clinical daily practice. Copyright © 2014 Sociedade Portuguesa de Cardiologia.

  15. High-normal blood pressure and the risk of cardiovascular disease.

    2009-08-01

    The guidelines of the Joint National Committee 7 from the USA on hypertension have unified the normal and high-normal blood pressure categories into a single entity termed ;prehypertension'. In contrast, The European Guidelines for the management of hypertension in 2007 considered ;prehypertensive' to be divided into normal and high-normal blood pressure. These patients with high-normal blood pressure or prehypertension might progress to hypertension over time. Previous studies have shown that high-normal blood pressure is a risk factor for cardiovascular disease (CVD) in Western countries and Japan. The combination of high-normal blood pressure and other cardiovascular risk factors increases the risks of CVD. Recently, metabolic syndrome has also been shown to be a risk factor for CVD. In Japan, the association between metabolic syndrome and CVD was also found to be significant. The risks for CVD incidence were similar among participants who had the same number of components, regardless of the presence of abdominal obesity. In the Japanese guidelines for the management of hypertension published in 2009, patients are considered to be in a high-risk group if they have diabetes, chronic kidney disease, 3 or more risk factors, target organ damage or CVD, even if they have only high-normal blood pressure, and appropriate antihypertensive therapy should be initiated.

  16. A multilevel analysis on the relationship between neighbourhood poverty and public hospital utilization: is the high Indigenous morbidity avoidable?

    2011-09-01

    Full Text Available Abstract Background The estimated life expectancy at birth for Indigenous Australians is 10-11 years less than the general Australian population. The mean family income for Indigenous people is also significantly lower than for non-Indigenous people. In this paper we examine poverty or socioeconomic disadvantage as an explanation for the Indigenous health gap in hospital morbidity in Australia. Methods We utilised a cross-sectional and ecological design using the Northern Territory public hospitalisation data from 1 July 2004 to 30 June 2008 and socio-economic indexes for areas (SEIFA from the 2006 census. Multilevel logistic regression models were used to estimate odds ratios and confidence intervals. Both total and potentially avoidable hospitalisations were investigated. Results This study indicated that lifting SEIFA scores for family income and education/occupation by two quintile categories for low socio-economic Indigenous groups was sufficient to overcome the excess hospital utilisation among the Indigenous population compared with the non-Indigenous population. The results support a reframing of the Indigenous health gap as being a consequence of poverty and not simplistically of ethnicity. Conclusions Socio-economic disadvantage is a likely explanation for a substantial proportion of the hospital morbidity gap between Indigenous and non-Indigenous populations. Efforts to improve Indigenous health outcomes should recognise poverty as an underlying determinant of the health gap.

    High-protein-low-carbohydrate (HP-LC) diets have become widespread. Yet their deleterious consequences, especially on glucose metabolism and arteries, have already been underlined. Our previous study (2) has already shown glucose intolerance with major arterial dysfunction in very old mice subjected to an HP-LC diet. The hypothesis of this work was that this diet had an age-dependent deleterious metabolic and cardiovascular outcome. Two groups of mice, young and adult (3 and 6 mo old), were subjected for 12 wk to a standard or to an HP-LC diet. Glucose and lipid metabolism was studied. The cardiovascular system was explored from the functional stage with Doppler-echography to the molecular stage (arterial reactivity, mRNA, immunohistochemistry). Young mice did not exhibit any significant metabolic modification, whereas adult mice presented marked glucose intolerance associated with an increase in resistin and triglyceride levels. These metabolic disturbances were responsible for cardiovascular damages only in adult mice, with decreased aortic distensibility and left ventricle dysfunction. These seemed to be the consequence of arterial dysfunctions. Mesenteric arteries were the worst affected with a major oxidative stress, whereas aorta function seemed to be maintained with an appreciable role of cyclooxygenase-2 to preserve endothelial function. This study highlights for the first time the age-dependent deleterious effects of an HP-LC diet on metabolism, with glucose intolerance and lipid disorders and vascular (especially microvessels) and cardiac functions. This work shows that HP-LC lead to equivalent cardiovascular alterations, as observed in very old age, and underlines the danger of such diet.

    A meta-analysis has shown that an asymmetry of the blood pressure (ABP) between arm≥15mmHg and perhaps≥10mmHg is associated with an increase of cardiovascular diseases. To describe the prevalence of ABP in patients presenting an uncontrolled blood pressure (BP) under treatment, an observational cross sectional study was conducted. Factors influencing prevalence of ABP were identified and relation of ABP with the frequency of the cardiovascular diseases or subclinicals organs damages was evaluated. A total of 2417 patients, 63.3±11.0years old, presenting uncontrolled BP (according ESC criteria) by a previous antihypertensive therapy were included. Only 36.8% (95% CI [34.9-38.7]) were presenting a between-arm difference in systolic blood pressure≥10mmHg, and 17.1% (95% CI [15.6-18.6])≥15mmHg.

    Cardiovascular protection of deep-seawater (DSW) drinking water was assessed using high-fat/cholesterol-fed hamsters in this study. All hamsters were fed a high-fat/cholesterol diet (12% fat/0.2% cholesterol), and drinking solutions were normal distiled water (NDW, hardness: 2.48ppm), DSW300 (hardness: 324.5ppm), DSW900 (hardness: 858.5ppm), and DSW1500 (hardness: 1569.0ppm), respectively. After a 6-week feeding period, body weight, heart rates, and blood pressures of hamsters were not influenced by DSW drinking waters. Serum total cholesterol (TC), triacylglycerol (TAG), atherogenic index, and malondialdehyde (MDA) levels were decreased (pdrinking-water groups, as compared to those in the NDW group. Additionally, increased (pdrinking-water groups. Hepatic low-density-lipoprotein receptor (LDL receptor) and cholesterol-7α-hydroxylase (CYP7A1) gene expressions were upregulated (pdrinking waters. These results demonstrate that DSW drinking water benefits the attenuation of high-fat/cholesterol-diet-induced cardiovascular disorders in hamsters.

    Globally, cardiovascular disease (CVD) is the leading cause of death among women. In China, the burden of CVD is increasing at an alarming rate; yet, it is underestimated and has important primary, secondary, and tertiary prevention issues. This article seeks to document the issues surrounding the increased rate of CVD among Chinese women and describe the etiological factors and potential strategies to decrease the burden of disease. The Medline, Current Information in Nursing and Allied Health Literature, Ovid, Science Direct, and Government Reports were searched using the key words heart disease, cardiovascular, ischemic heart disease, coronary, women, and Chin (China, Chinese). Articles were selected if they described epidemiological factors and/or interventions to address heart disease in Chinese women. Rapid industrialization and urbanization in China have extended the life expectancy of the population, particularly among women. Social, political, and economic factors have caused lifestyle changes that have a direct bearing on health. Heart disease has become the most common cause of death among Chinese women and the second most common cause among men. Paradoxically, prevention and management strategies are sparse in relation to the high prevalence. A number of modifiable risk factors have been identified as major contributors of CVD and should be a focus of primary, secondary, and tertiary prevention. Cardiovascular disease is already a leading cause of death and disability among Chinese women. The high prevalence of risk factors and low rate of awareness, treatment, and control signal an urgent need for focusing on this issue in Chinese women. Strategies on individual, community, and government levels are recommended. Involving Chinese nurses in these strategies is essential.

    Full Text Available BACKGROUND: To test the inflammatory origin of cardiovascular disease, as opposed to its origin in western lifestyle. Population-based assessment of the prevalences of cardiovascular risk factors and cardiovascular disease in an inflammation-prone African population, including electrocardiography and ankle-arm index measurement. Comparison with known prevalences in American and European societies. METHODOLOGY/PRINCIPAL FINDINGS: Traditional population in rural Ghana, characterised by adverse environmental conditions and a high infectious load. Population-based sample of 924 individuals aged 50 years and older. Median values for cardiovascular risk factors, including waist circumference, BMI, blood pressure, and markers of glucose and lipid metabolism and inflammation. Prevalence of myocardial infarction detected by electrocardiography and prevalence of peripheral arterial disease detected by ankle-arm index. When compared to western societies, we found the Ghanaians to have more proinflammatory profiles and less cardiovascular risk factors, including obesity, dysglycaemia, dyslipidaemia, and hypertension. Prevalences of cardiovascular disease were also lower. Definite myocardial infarction was present in 1.2% (95%CI: 0.6 to 2.4%. Peripheral arterial disease was present in 2.8% (95%CI: 1.9 to 4.1%. CONCLUSIONS/SIGNIFICANCE: Taken together, our data indicate that for the pathogenesis of cardiovascular disease inflammatory processes alone do not suffice and additional factors, probably lifestyle-related, are mandatory.

    Full Text Available Congenital syphilis continues to be a preventable cause of global stillbirth and neonatal morbidity and mortality. Shortages of injectable penicillin, the only recommended treatment for pregnant women and infants with syphilis, have been reported by high-morbidity countries. We sought to estimate current and projected annual needs for benzathine penicillin in antenatal care settings for 30 high morbidity countries that account for approximately 33% of the global burden of congenital syphilis.Proportions of antenatal care attendance, syphilis screening coverage in pregnancy, syphilis prevalence among pregnant women, and adverse pregnancy outcomes due to untreated maternal syphilis reported to WHO were applied to 2012 birth estimates for 30 high syphilis burden countries to estimate current and projected benzathine penicillin need for prevention of congenital syphilis.Using current antenatal care syphilis screening coverage and seroprevalence, we estimated the total number of women requiring treatment with at least one injection of 2.4 MU of benzathine penicillin in these 30 countries to be 351,016. Syphilis screening coverage at or above 95% for all 30 countries would increase the number of women requiring treatment with benzathine penicillin to 712,030. Based on WHO management guidelines, 351,016 doses of weight-based benzathine penicillin would also be needed for the live-born infants of mothers who test positive and are treated for syphilis in pregnancy. Assuming availability of penicillin and provision of treatment for all mothers diagnosed with syphilis, an estimated 95,938 adverse birth outcomes overall would be prevented including 37,822 stillbirths, 15,814 neonatal deaths, and 34,088 other congenital syphilis cases.Penicillin need for maternal and infant syphilis treatment is high among this group of syphilis burdened countries.

    Psoriasis is a common, chronic, immune-mediated inflammatory disorder. The disease is associated with several co-morbidities including cardiovascular disease, metabolic syndrome, and psychiatric disorders. It is important to identify and treat these co-morbidities because they have a strongly negative effect on the overall health of patients with psoriasis. Unfortunately, these co-morbidities are often overlooked and/or left untreated. Therefore, the aim of this review is to discuss the mechanisms of how co-morbidities are associated with psoriasis as well as implications for the clinic to be able to recognize such co-morbidities. Areas covered: This is a review of studies investigating and discussing co-morbidities of psoriasis and screening. Literature was retrieved by searching on the PubMed database using individual and combined search terms related to relevant co-morbidities. Expert commentary: Effective management of psoriasis involves targeting of both psoriasis and co-morbidities.

  15. Naringin Improves Diet-Induced Cardiovascular Dysfunction and Obesity in High Carbohydrate, High Fat Diet-Fed Rats

    2013-02-01

    Full Text Available Obesity, insulin resistance, hypertension and fatty liver, together termed metabolic syndrome, are key risk factors for cardiovascular disease. Chronic feeding of a diet high in saturated fats and simple sugars, such as fructose and glucose, induces these changes in rats. Naturally occurring compounds could be a cost-effective intervention to reverse these changes. Flavonoids are ubiquitous secondary plant metabolites; naringin gives the bitter taste to grapefruit. This study has evaluated the effect of naringin on diet-induced obesity and cardiovascular dysfunction in high carbohydrate, high fat-fed rats. These rats developed increased body weight, glucose intolerance, increased plasma lipid concentrations, hypertension, left ventricular hypertrophy and fibrosis, liver inflammation and steatosis with compromised mitochondrial respiratory chain activity. Dietary supplementation with naringin (approximately 100 mg/kg/day improved glucose intolerance and liver mitochondrial dysfunction, lowered plasma lipid concentrations and improved the structure and function of the heart and liver without decreasing total body weight. Naringin normalised systolic blood pressure and improved vascular dysfunction and ventricular diastolic dysfunction in high carbohydrate, high fat-fed rats. These beneficial effects of naringin may be mediated by reduced inflammatory cell infiltration, reduced oxidative stress, lowered plasma lipid concentrations and improved liver mitochondrial function in rats.

    Background Rheumatoid Arthritis (RA) is an autoimmune disease characterized by chronic inflammation of the joints that affects approximately 1% of the population worldwide. The HLA-DRB1 gene locus plays a major role in genetic susceptibility to RA, a condition that has been associated with a high cardiovascular morbidity and mortality in many studies. Methodology/Principal Findings The aim of this work was to investigate which types of HLA class II genes are associated with RA in patients from the Brazilian Amazon and their influence on high cardiovascular risk status in this population. For this purpose, a case-control study was carried out with a total of 350 non-Indian individuals made up of a cohort of 132 consecutive RA sufferers and 218 healthy controls. A χ2 test showed that HLADRB1*04 (p<0.0016; OR = 1.89; 95% CI = 1.29–2.79) and HLADRB1*10 (p = 0.0377; OR = 3.81; 95% CI = 1.16–12.50) are the major HLA genes associated with susceptibility to RA. A logistic regression model also showed that the interaction between HLADRB1*04 (p = 0.027; OR = 6.02; 95% CI = 1.21–29.7), age (p = 0.0001; OR = 1.26; 95% CI = 1.13–1.39) and smoking (p = 0.0001; OR = 23.6; 95% CI = 4.25–32.1) is associated with a probability of a high cardiovascular risk status at an early age. Conclusions/Significance The results of this study show for the first time that HLA class II type is associated with RA in Brazilian Amazon populations and that a specific interaction between the HLA-DRB1*04 gene and smoking is associated with a high cardiovascular risk status, as initially reported in the European population. This study therefore contributes to an understanding of gene-environment interactions in RA patients. PMID:22912672

  17. Circulating CD62E+ microparticles and cardiovascular outcomes.

    Directory of Open Access Journals (Sweden)

    Soon-Tae Lee

    Full Text Available BACKGROUND: Activated endothelial cells release plasma membrane submicron vesicles expressing CD62E (E-selectin into blood, known as endothelial microparticles (EMPs. We studied whether the levels of endothelial microparticles expressing CD62E(+, CD31(+/Annexin-V(+, or CD31(+/CD42(- predict cardiovascular outcomes in patients with stroke history. METHODS/PRINCIPAL FINDINGS: Patients with stroke history at least 3 months prior to enrolment were recruited. Peripheral blood EMP levels were measured by flow cytometry. Major cardiovascular events and death were monitored for 36 months. Three hundred patients were enrolled, of which 298 completed the study according to protocol. Major cardiovascular events occurred in 29 patients (9.7%. Nine patients died, five from cardiovascular causes. Cumulative event-free survival rates were lower in patients with high levels of CD62E(+ microparticles. Multivariate Cox regression analysis adjusted for cardiovascular risk factors, medications and stroke etiologic groups showed an association between a high CD62E(+ microparticle level and a risk of major cardiovascular events and hospitalization. Levels of other kinds of EMPs expressing CD31(+/Annexin-V(+ or CD31(+/CD42(- markers were not predictive of cardiovascular outcomes. CONCLUSION: A high level of CD62E(+ microparticles is associated with cardiovascular events in patients with stroke history, suggesting that the systemic endothelial activation increases the risk for cardiovascular morbidities.

    Full Text Available The incidence of significant obesity is rising across the globe. These patients often have a clustering of cardiovascular risk factors and are frequently referred for noninvasive cardiac imaging tests. Stress echocardiography (SE is widely used for assessment of patients with known or suspected coronary artery disease (CAD, but its clinical utility in morbidly obese patients (in whom image quality may suffer due to body habitus has been largely unknown. The recently published Stress Ultrasonography in Morbid Obesity (SUMO study has shown that SE, when performed appropriately with ultrasound contrast agents (whether performed with physiological or pharmacological stress, has excellent feasibility and appropriately risk stratifies morbidly obese patients, including identification of patients who require revascularization. This article reviews the evidence supporting the use of echocardiographic techniques in morbidly obese patients for assessment of known or suspected CAD and briefly discusses other noninvasive modalities, including magnetic resonance and nuclear techniques, comparing and contrasting these techniques against SE.

    Antiphospholipid syndrome (APLS) is an autoimmune hypercoagulable syndrome characterized by thrombotic and obstetric manifestations. We sought to determine the rate of APLS feature in patients tested positive for antiphospholipid antibodies (APLA) regardless of the serum level of anticardiolipin (ACL) and/or anti-β2-glycoprotein I (β2GPI) antibodies. An inception cohort of individuals who were tested positive for ACL and/or β2GPI IgG/IgM antibody, and/or lupus anticoagulant (LAC) on two occasions of at least 12 weeks apart. A total of 243 patients were included; their mean age was 40.1 ± 15.9 years. Thrombotic vascular events occurred in 118 patients (48.5%) of the entire cohort, of which 62 patients (25.5%) suffered from an arterial event and 56 patients (23%) from thrombotic venous events. Obstetrical morbidity occurred in 106 female patients (43.6%). In our cohort, we found no difference in the frequency of thrombotic or obstetric manifestations of APLS between patients with ACL IgG/IgM of low serum antibody level (20 U). We suggest that in 'real life' the diagnosis of APLS should not be excluded because of low titer of APLA.

    The radiation related health risks to astronauts is of particular concern to NASA. Data support that exposure to radiation is associated with a number of disorders including a heightened risk for cardiovascular diseases. Independent of radiation, altered nutrient status (e.g. high dietary iron) also increases ones risk for cardiovascular disease. However, it is unknown whether exposure to radiation in combination with high dietary iron further increases ones cardiovascular risk. The intent of our proposal is to generate compulsory data examining the combined effect of radiation exposure and iron overload on sensitivity to radiation injury to address HRP risks: 1) Risk Factor of Inadequate Nutrition; 2) Risk of Cardiac Rhythm Problems; and 3) Risk of Degenerative Tissue or other Health Effects from Space Radiation. Towards our goal we propose two distinct pilot studies using the following specific aims: Vascular Aim 1: To determine the short-term consequences of the independent and combined effects of exposure to gamma radiation and elevated body iron stores on measures of endothelial function and cell viability and integrity. We hypothesize that animals that have high body iron stores and are exposed to gamma radiation will show a greater reduction in endothelial dependent nitric oxid production and larger pathological changes in endothelial integrity than animals that have only 1 of those treatments (either high iron stores or exposure to gamma radiation). Vascular Aim 2: Identify and compare the effects of gamma radiation and elevated body iron stores on the genetic and epigenetic regulation of proteins associated with endothelial cell function. We hypothesize that modifications of epigenetic control and posttranslational expression of proteins associated with endothelial cell function will be differentially altered in rats with high body iron stores and exposed to gamma radiation compared to rats with only 1 type of treatment. Cardiac Aim 1: To determine the

    Coffee and tea consumption recommendations for a healthy diet have been changing in recent years as it has increased the level of evidence on their benefits has increased. To know the frequency of coffee and tea consumption of in a high cardiovascular risk Mediterranean population (CVR) and to analyze whether there are differences between the consumption of these drinks by cardiovascular risk factors. A cross-sectional study was carried out on 945 people (340 males, 605 females) (67.4+/-6.2 years old) with high CVR recruited in primary care centres of Valencia, included in the PREDIMED study. Coffee and tea consumption has been determined through a validated questionnaire. We analyzed biochemical, clinical and anthropometric variables by standard methods. Tea consumption is very low in this Mediterranean population (0.4+/-1.6 cups/weeks). By contrast, coffee consumption averaged nearly one cup per day (6.5+/-5.2 cups/weeks). Hypertensive patients showed a lower overall consumption of coffee than in non-hypertensive patients (6.6+/-5.1 vs 7.3+/-5.9; P=0.023 respectively). These differences were greatest when caffeinated coffee consumption is analyzed (2.9+/-4.5 vs 4.3+/-5.3, Pcoffee and tea than non-diabetics (P=0.015 and P=0.022 respectively), these differences being greater for caffeinated coffee (Pcoffee consumption pattern, based on traditional recommendations, is observed, that as a result of new scientific evidence should be update.

    Full Text Available Aims: To test the suggested association of low nephron number and later development of renal and cardiovascular disease we investigated the effects of high sodium diet in heterozygous GDNF+/- mice. Methods: Aged wild type and GDNF+/- mice were grouped together according to high sodium (HS, 4% or low sodium (LS, 0.03% diet for 4 weeks. The heart, the aorta and the kidneys were processed for morphometric and stereological evaluations and TaqMan PCR. Results: On HS GDNF+/- mice showed significantly higher drinking volume and urine production than wt and mean arterial blood pressure tended to be higher. Heart weight was higher in GDNF+/- than in wt, but the difference was only significant for LS. HS significantly increased cardiac interstitial tissue in GDNF+/-, but not in wt. On LS GDNF+/- mice had significantly larger glomeruli than wt and HS led to an additional two fold increase of glomerular area compared to LS. On electron microscopy glomerular damage after HS was seen in GDNF+/-, but not in wt. Dietary salt intake modulated renal IL-10 gene expression in GDNF+/-. Conclusion: In the setting of 30% lower nephron number HS diet favoured maladaptive changes of the kidney as well as of the cardiovascular system.

    Morbid obesity has been shown to increase the risk to develop hepatic steatosis, also referred to as non-alcoholic fatty liver disease (NAFLD). Emerging evidence suggests that the severity of NAFLD may associate with increased serum levels of inflammatory markers as well as decreased concentration of mediators with anti-inflammatory actions, such as tumor necrosis factor alpha (TNF-α) and interleukin (IL) 10, respectively. We thus examined the serum levels of TNF-α and IL-10 in 102 morbidly obese women and men (body mass index > 40 kg/m(2)), exhibiting different grades of NAFLD. Blood glucose, glycated hemoglobin, insulin, the homeostatic model assessment of insulin resistance (HOMA-IR), total cholesterol, triglycerides, high- and low-density lipoproteins, parameters of liver function, TNF-α, and IL-10 were measured in each subject. The stage of NAFLD was estimated by abdominal ultrasound imaging. In comparison with morbidly obese subjects without steatosis, morbidly obese patients with NAFLD showed increased age (39.23 ± 9.80 years), HOMA-IR (6.74 ± 1.62), total cholesterol (219.7 ± 9.58 mg/dl), aspartate aminotransferase (36.25 ± 3.24 UI/l), gamma-glutamyl transpeptidase (37.12 ± 3.41 UI/l), and TNF-α (37.41 ± 1.72 pg/ml) as well as decreased serum levels of IL-10 (61.05 ± 2.43 pg/ml). Interestingly, the systemic levels of TNF-α increased, while IL-10 decreased in accordance with the severity of NAFLD, which supports a role for systemic inflammatory mediators in promoting steatosis progression. Further clinical prospective studies need to be addressed to elucidate the role of TNF-α and IL-10 in the development of NAFLD while also establishing their clinical utility in the assessment of morbidly obese patients at higher risk to develop severe steatosis.

    Cardiovascular morbidity and mortality are increased in acromegaly. In fact, GH and IGF-I excess induces a specific cardiomyopathy. The early stage of acromegaly is characterized by the hyperkinetic syndrome (high heart rate and increased systolic output). Frequently, concentric biventricular hypertrophy and diastolic dysfunction occur in acromegaly, leading to an impaired systolic function ending in heart failure if the disease is untreated or unsuccessfully untreated. Besides, abnormalities of cardiac rhythm and of valves have been also described in acromegaly. The coexistence of other complications, such as arterial hypertension and diabetes, aggravates the acromegalic cardiomyopathy. The suppression of GH/IGF-I following an efficacious therapy could decrease left ventricular mass and improve cardiac function. In conclusion, a careful evaluation of cardiac function, morphology and activity seems to be mandatory in acromegaly.

    Full Text Available To test the hypothesis that high-intensity swim training improves cardiovascular health status in sedentary premenopausal women with mild hypertension, sixty-two women were randomized into high-intensity (n=21; HIT, moderate-intensity (n=21; MOD, and control groups (n=20; CON. HIT performed 6–10 × 30 s all-out swimming interspersed by 2 min recovery and MOD swam continuously for 1 h at moderate intensity for a 15-week period completing in total 44±1 and 43±1 sessions, respectively. In CON, all measured variables were similar before and after the intervention period. Systolic BP decreased (P<0.05 by 6±1 and 4±1 mmHg in HIT and MOD; respectively. Resting heart rate declined (P<0.05 by 5±1 bpm both in HIT and MOD, fat mass decreased (P<0.05 by 1.1±0.2 and 2.2±0.3 kg, respectively, while the blood lipid profile was unaltered. In HIT and MOD, performance improved (P<0.05 for a maximal 10 min swim (13±3% and 22±3%, interval swimming (23±3% and 8±3%, and Yo-Yo IE1 running performance (58±5% and 45±4%. In conclusion, high-intensity intermittent swimming is an effective training strategy to improve cardiovascular health and physical performance in sedentary women with mild hypertension. Adaptations are similar with high- and moderate-intensity training, despite markedly less total time spent and distance covered in the high-intensity group.

    Standard treatments of high-grade Cervical intraepithelial neoplasia (CIN) are conisation procedures. Theses methods have proven effectiveness but are associated with an increased risk of subsequent pregnancy complications. Recently, photodynamic therapy (PDT) of CIN using hexylaminolevulinate (HAL) may represent an alternative treatment without the risk of cervical insufficiency or scaring. This study aims to evaluate the economical aspect of CIN treatment including associated pregnancy complications by comparing both methods. We developed model treatment pathways for both conisation procedures and PDT using HAL. Thereafter, we calculated total costs for both treatment pathways including necessary re-treatments or alternative treatments. The estimated impact of conisation-related cervical insufficiency, prematurity, perinatal morbidity and life-long disability were determined. The total additional costs per conisation due to perinatal morbidity were calculated. The total cost of treatment for CIN with a conisation procedure alone was 1,473 €, whereas the PDT procedure alone accounted for 1,386 €, based of assumptions of a 50% re-PDT rate, a 70% response rate and costs of 500 € for the PDT intervention itself. We computed 71, 144 and 545 newborns born prematurely due to conisation procedures treatment with PDT given the above-mentioned assumptions were 1,558 €. For Germany, PDT has the potential to be a cost-effective treatment for high-grade CIN compared to conisation procedure. Most important, the increased perinatal morbidity, perinatal mortality and associated costs after conisation procedures are significant and may be reduced by the implementation of PDT in CIN treatment.

    We have reported that high job strain was associated with a significantly higher diastolic blood pressure (DBP) of 4.5 mm Hg during the working hours, irrespective of BP reactivity to a stress test. We report the final results of the first 5-year follow-up study, which aimed to assess the respective influences of perception of professional strain and cardiovascular reactivity to a mental stress test on BP. A cohort of 292 healthy subjects (mean+/-SEM age, 38+/-1 years) was followed up for progression to hypertension outcome, which was defined as an increase in systolic blood pressure (SBP) or DBP >7 mm Hg or a DBP >95 mm Hg during follow-up. None of the subjects was lost to follow-up, and 209 subjects completed the study. The high-strain (HS) group, representing 20.9% of the subjects, was compared with the remaining subjects (non-high-strain [NHS]). Similarly, the subjects with the highest BP stress reactivity (HR; 20.9% of subjects) were compared with the remaining subjects (NHR). Progression to hypertension was reached by 93 subjects (31.8%). Kaplan-Meier survival estimates revealed that neither HS nor HR increased the incidence of progression to hypertension. End-of-follow-up 24-hour ambulatory BPs that were similar in HS and NHS (120+/-2 vs 120+/-1 mm Hg, respectively) and in HR and NHR (122+/-2 vs 120+/-1 mm Hg, respectively) confirmed our findings. Age, alcohol, salt diet, body mass index, and occupation did not interfere with our results. In conclusion, cardiovascular HR and HS do not appear to be major risk markers for future high BP in healthy, young adults.

  9. Cardiovascular comorbiditiy in psoriasis

    2011-01-01

    Full Text Available The chronic inflammatory nature of psoriasis is also thought to predispose patients to other diseases with an inflammatory component, the most notable being cardiovascular and metabolic (cardiometabolite disorders. This concept is supported by studies showing that psoriasis is associated with cardiovascular risk factors like diabetes, obesity, hypertension, dyslipidemia, smoking and diseases including MI. Given the increased prevalence of cardiovascular co morbidities in patients, dermatologists treating psoriasis need to approach the disease as a potentially multisystem disorder and must alert these patients to the potentially negative effects of their disease.

    Bococizumab is a humanized monoclonal antibody that inhibits proprotein convertase subtilisin-kexin type 9 (PCSK9) and reduces levels of low-density lipoprotein (LDL) cholesterol. We sought to evaluate the efficacy of bococizumab in patients at high cardiovascular risk. In two parallel, multinational trials with different entry criteria for LDL cholesterol levels, we randomly assigned the 27,438 patients in the combined trials to receive bococizumab (at a dose of 150 mg) subcutaneously every 2 weeks or placebo. The primary end point was nonfatal myocardial infarction, nonfatal stroke, hospitalization for unstable angina requiring urgent revascularization, or cardiovascular death; 93% of the patients were receiving statin therapy at baseline. The trials were stopped early after the sponsor elected to discontinue the development of bococizumab owing in part to the development of high rates of antidrug antibodies, as seen in data from other studies in the program. The median follow-up was 10 months. At 14 weeks, patients in the combined trials had a mean change from baseline in LDL cholesterol levels of -56.0% in the bococizumab group and +2.9% in the placebo group, for a between-group difference of -59.0 percentage points (P<0.001) and a median reduction from baseline of 64.2% (P<0.001). In the lower-risk, shorter-duration trial (in which the patients had a baseline LDL cholesterol level of ≥70 mg per deciliter [1.8 mmol per liter] and the median follow-up was 7 months), major cardiovascular events occurred in 173 patients each in the bococizumab group and the placebo group (hazard ratio, 0.99; 95% confidence interval [CI], 0.80 to 1.22; P=0.94). In the higher-risk, longer-duration trial (in which the patients had a baseline LDL cholesterol level of ≥100 mg per deciliter [2.6 mmol per liter] and the median follow-up was 12 months), major cardiovascular events occurred in 179 and 224 patients, respectively (hazard ratio, 0.79; 95% CI, 0.65 to 0.97; P=0.02).

    To investigate the morbidity of higher radiation doses in prostate cancer patients. Five hundred eighty-five men treated with seed implantation and external beam irradiation were followed a median of 5 years (range, 2-11). Hormonal therapy (HT) of 9 months duration was used in 504 (86.2%) patients. The biologic effective dose (BED) was calculated using an alpha/beta of 2. Urinary incontinence (UI) and symptoms (IPSS) were prospectively collected. Rectal morbidity was scored according to the Radiation Therapy Oncology Group (RTOG) scale. Two BED dose groups of 220 Gy (n=136) were used. Comparisons of means were made by Student's t test, and the associations were tested by chi-square analysis (Pearson). Urinary retention developed in 36 (6.2%) and was not associated with BED or IPSS. Retention occurred more often with prostate volume >50 cc (17%, p=0.001). The median change in urinary symptoms (IPSS) was 1. Sixty-one percent with high BED were more likely to have increased postimplant symptoms compared with 39% with lower BED (p=0.025; odds ratio [OR], 1.107; 95% confidence interval [CI], 1.10-1.21). UI occurred in 25 patients (4.3%) and was only associated with a postimplant transurethral resection of the prostate (TURP) (n=25), 16% vs. 2.3% for no TURP (p=0.001; OR, 8; 95% CI, 2.4-27). Of the 373 patients initially potent, 204 (54.7%) maintained potency. Impotence was only associated with age at implant (p=0.001) and HT (p=0.004). Sixty-two (10.6%) patients had Grade 1-2 and 4 patients had Grade 3-4 (0.7%, 2 ulcers and 2 fistulas) rectal complications. Three of the Grade 3/4 complications occurred with a dose 220 Gy does not seem to increase morbidity. (c) 2010 American Brachytherapy Society. Published by Elsevier Inc. All rights reserved.

    Background Electronic health (eHealth) literacy is a growing area of research parallel to the ongoing development of eHealth interventions. There is, however, little and conflicting information regarding the factors that influence eHealth literacy, notably in chronic disease. We are similarly ill-informed about the relationship between eHealth and health literacy, 2 related yet distinct health-related literacies. Objective The aim of our study was to investigate the demographic, socioeconomic, technology use, and health literacy predictors of eHealth literacy in a population with moderate-to-high cardiovascular risk. Methods Demographic and socioeconomic data were collected from 453 participants of the CONNECT (Consumer Navigation of Electronic Cardiovascular Tools) study, which included age, gender, education, income, cardiovascular-related polypharmacy, private health care, main electronic device use, and time spent on the Internet. Participants also completed an eHealth Literacy Scale (eHEALS) and a Health Literacy Questionnaire (HLQ). Univariate analyses were performed to compare patient demographic and socioeconomic characteristics between the low (eHEALS<26) and high (eHEALS≥26) eHealth literacy groups. To then determine the predictors of low eHealth literacy, multiple-adjusted generalized estimating equation logistic regression model was used. This technique was also used to examine the correlation between eHealth literacy and health literacy for 4 predefined literacy themes: navigating resources, skills to use resources, usefulness for oneself, and critical evaluation. Results The univariate analysis showed that patients with lower eHealth literacy were older (68 years vs 66 years, P=.01), had lower level of education (P=.007), and spent less time on the Internet (P<.001). However, multiple-adjusted generalized estimating equation logistic regression model demonstrated that only the time spent on the Internet (P=.01) was associated with the level of e

    prueba del score de calcio coronario a un paciente con factores de riesgo cardiovascular. Se puede observar que muchos de los factores de riesgo que se correlacionan con un valor elevado de "score" de calcio coronario pueden ser modificables: cesar el hábito de fumar o realizar ejercicio.Introduction: it has been found through multiple studies that coronary calcium score is a good predictor of coronary disease in asymptomatic individuals with one or more cardiovascular risk factors; therefore it would be ideal to perform this test in order to stratify its risk, but due to economic factors this is not possible in most cases. The model presented allows predicting the probability that a patient may have a high coronary calcium score by means of his cardiovascular risk factors. The originality of the model is that it also comprises "protector" factors that diminish such probability. Methods: study of cases and controls in asymptomatic patients with cardiovascular risk factors to whom a PCC had been performed. The cases are patients with coronary calcium score greater than percentile 75 for his age and gender; the control case relationship is 2:1. Results: ages ranged between 35 and 75 years; 14.4% were female; 44.4% had family history of CHD; 34.4% were hypertensive; 38.9% had high total cholesterol; 24.4% had HDL cholesterol under 40 mg/dl; 33.3% had LDL cholesterol greater than 160 mg/dl; 25.6% were cigarette smokers; 23.3% were sedentary; 13.3% were periodical alcohol consumers; 15.6% were obese (BMI > 30; 18.9% exercised periodically and 34.4% received statins. Cardiovascular risk factors correlated with high coronary calcium score are recorded in table 1. In the logistic regression model, factors having a p table 2 are obtained. Expression for the model would be: The values of ci values are 1, if the factor is present and 0 if it is not. Conclusions: this model does not pretend to replace stratification through Framinghan model; on the contrary, it is a complement that

    A significant number of surgical patients are at risk of intra- or post-operative complications or both, which are associated with increased lengths of stay, costs, and mortality. Reducing these risks is important for the individual patient but also for health-care planners and managers. Insufficient tissue perfusion and cellular oxygenation due to hypovolemia, heart dysfunction or both is one of the leading causes of perioperative complications. Adequate perioperative management guided by effective and timely hemodynamic monitoring can help reduce the risk of complications and thus potentially improve outcomes. In this review, we describe the various available hemodynamic monitoring systems and how they can best be used to guide cardiovascular and fluid management in the perioperative period in high-risk surgical patients.

  19. Do ACE inhibitors all provide the same outcomes benefits in high-risk cardiovascular patients?

    2008-08-01

    The Heart Outcomes Prevention (HOPE) trial was the first to demonstrate the benefits of the angiotensin-converting enzyme (ACE) inhibitor ramipril for high-risk cardiovascular patients. Whether the cardioprotective effects seen in HOPE and other trials are specific to distinct ACE inhibitors remains controversial. Evidence of a lack of class effect for ACE inhibitors has policy and financial implications related to reference pricing by insurers and inclusion on pharmacy formularies. Because head-to-head trials comparing the different ACE inhibitors are unforeseen, clinicians and administrators must rely on secondary-level data and observational studies. Only a handful of studies have sought to address the dispute over a class effect among ACE inhibitors, which is reviewed in this article.

    The HOPE and EUROPA clinical studies have shown that treatment with the angiotensin-converting enzyme (ACE) inhibitors, ramipril and perindopril, may reduce the occurrence of major cardiovascular events in patients with proven atherosclerotic disease. The recently published results of the PRoFESS and TRANSCEND trials completed the much needed information concerning the use of an angiotensin receptor blocker for patients at high risk of cardiovascular events. PROFESS compared a therapy of telmisartan 80 mg daily with placebo in patients with a recent ischemic stroke. The difference in the primary outcome of first recurrent stroke was not statistically significant between telmisartan and placebo. The secondary outcome of major cardiovascular events showed a relative risk reduction (RRR) of 7% in favour of telmisartan. This tended to be significant (p = 0.06) despite a rather short follow-up period of only 28 months. In TRANSCEND 5926 patients at high risk for cardiovascular events were randomized to a treatment with telmisartan 80 mg daily or placebo for a mean duration of follow-up of 56 months. The primary composite outcome of cardiovascular death, myocardial infarction, stroke or hospitalization for heart failure showed a non-significant 8% RRR in favour of the telmisartan treated patients. The main secondary outcome of cardiovascular death and myocardial infarction or stroke as used in the HOPE trial showed a non-significant RRR of 13% in favour of telmisartan treated patients (p = 0.068 adjusted for multiplicity of comparisons). In comparing the Kaplan-Meier curves for the endpoint of major cardiovascular events used in HOPE, EUROPA, TRANSCEND and PRoFESS, the trends are similar. Results of most of the recently published trials have been neutral.This could partly be explained by major improvements in the optimal background therapy of the patients included. Nevertheless, the results of PRoFESS and TRANSCEND do not contradict the results from previous studies with

    The objective of this study was to determine the effects of a high-fructose diet on cardiovascular disease (CVD)-related parameters in growing rats. Three-week-old female Sprague Dawley rats were randomly assigned to four experimental groups; a regular diet group (RD: fed regular diet based on AIN-93G, n = 8), a high-fructose diet group (30Frc: fed regular diet with 30% fructose, n = 8), a high-fat diet group (45Fat: fed regular diet with 45 kcal% fat, n = 8) or a high fructose with high-fat diet group (30Frc + 45Fat, fed diet 30% fructose with 45 kcal% fat, n = 8). After an eight-week treatment period, the body weight, total-fat weight, serum glucose, insulin, lipid profiles and pro-inflammatory cytokines, abdominal aortic wall thickness, and expressions of eNOS and ET-1 mRNA were analyzed. The result showed that total-fat weight was higher in the 30Frc, 45Fat, and 30Frc + 45Fat groups compared to the RD group (p growing rats had similar negative effects on CVD-related parameters.

    Full Text Available Obesity promotes cardiac and cerebral microcirculatory dysfunction that could be improved by incretin-based therapies. However, the effects of this class of compounds on neuro-cardiovascular system damage induced by high fat diet remain unclear. The aim of this study was to investigate the effects of incretin-based therapies on neuro-cardiovascular dysfunction induced by high fat diet in Wistar rats.We have evaluated fasting glucose levels and insulin resistance, heart rate variability quantified on time and frequency domains, cerebral microcirculation by intravital microscopy, mean arterial blood pressure, ventricular function and mitochondrial swelling. High fat diet worsened biometric and metabolic parameters and promoted deleterious effects on autonomic, myocardial and haemodynamic parameters, decreased capillary diameters and increased functional capillary density in the brain. Biometric and metabolic parameters were better improved by glucagon like peptide-1 (GLP-1 compared with dipeptdyl peptidase-4 (DPP-4 inhibitor. On the other hand, both GLP-1 agonist and DPP-4 inhibitor reversed the deleterious effects of high fat diet on autonomic, myocardial, haemodynamic and cerebral microvascular parameters. GLP-1 agonist and DPP-4 inhibitor therapy also increased mitochondrial permeability transition pore resistance in brain and heart tissues of rats subjected to high fat diet.Incretin-based therapies improve deleterious cardiovascular effects induced by high fat diet and may have important contributions on the interplay between neuro-cardiovascular dynamic controls through mitochondrial dysfunction associated to metabolic disorders.

    Full Text Available Abstract Background Screening with ankle-brachial index (ABI measurement could be clinically relevant to avoid cardiovascular events in subjects with asymptomatic atherosclerosis. To assess the practical impact of guidelines regarding the use of ABI as a screening tool in general practice, the corresponding number needed to screen, including the required time investment, and the feasibility of ABI performance, was assessed. Methods An observational study was performed in the setting of 955 general practices in the Netherlands. Overall, 13,038 subjects of ≥55 years presenting with symptoms of intermittent claudication and/or presenting with ≥ one vascular risk factor were included. Several guidelines recommend the ABI as an additional measurement in selected populations for risk assessment for cardiovascular morbidity. Results Screening of the overall population of ≥50 years results in ≈862 subjects per general practice who should be screened, resulting in a time-requirement of approximately 6 weeks of full time work. Using an existing clinical prediction model, 247 patients per general practice should be screened for PAD by ABI measurement. Conclusion Screening the entire population of ≥50 years will in our opinion not be feasible in general practice. A more rationale and efficient approach might be screening of subsets of the population of ≥55 years based on a clinical prediction model.

    2012-03-01

    Multiple New Zealand and other international studies have identified gaps in the management of those identified at high risk of a future cardiovascular (CV) event. This study sought to explore the views of health professionals about the barriers and facilitators present within the current primary health care system to the optimal management of those at high CV risk. This qualitative study utilised a focus group methodology to examine the barriers and facilitators within primary health care (PHC), and employed a general inductive approach to analyse the text data. The analysis of text data resulted in the emergence of interrelated themes, underpinned by subthemes. The patient, their circumstances and their characteristics and perceptions provided the first key theme and subthemes. The next key theme was primary health care providers, with subthemes of communication and values and beliefs. The general practice was the third theme and included multiple subthemes: implementation planning and pathway development, time and workload and roles and responsibilities. The final main theme was the health system with the subthemes linking to funding and leadership. This study determined the factors that act as barriers and facilitators to the effective management of those at high CV risk within the New Zealand PHC sector. General practice has a pivotal role in preventive health care, but to succeed there needs to be a refocusing of the PHC sector, requiring support from policy makers, District Health Boards and Primary Health Organisations, as well as those working in the sector.

    2011-01-01

    The article presents the results of comparative study of groups of subjects with low and high level of psychoticism. Heart rate, heart rate responses to inspiratory and expiratory Valsalva maneuvers, and blood pressure were measured before and after presentation of the texts with validated negative content in groups of subjects with low and high psychoticism scores. It was hypothesized that subjects with high level of psychoticism would be less engaged in the processing of negative contents of the texts and their physiological reactivity (physiological resources submitted for support of cognitive processing) would be less pronounced compared to subjects with low level of psychoticism. Significant main effect of psychoticism was obtained for changes in heart rate to expiratory Valsalva maneuver after presentations of the texts. Significant interaction effects of gender and psychoticism were obtained for systolic blood pressure. Other cardiovascular variables were not sensitive to the level of psychoticism. These effects of psychoticism were independent of other individual traits, such as neuroticism, extraversion, lie (social desirability), anger, trait anxiety and depression.

    Even at low-density lipoprotein cholesterol (LDL-C) goal, patients with cardiometabolic abnormalities remain at high risk of cardiovascular events. This paper aims (i) to critically appraise evidence for elevated levels of triglyceride-rich lipoproteins (TRLs) and low levels of high-density lipoprotein cholesterol (HDL-C) as cardiovascular risk factors, and (ii) to advise on therapeutic strategies for management. Current evidence supports a causal association between elevated TRL and their remnants, low HDL-C, and cardiovascular risk. This interpretation is based on mechanistic and genetic studies for TRL and remnants, together with the epidemiological data suggestive of the association for circulating triglycerides and cardiovascular disease. For HDL, epidemiological, mechanistic, and clinical intervention data are consistent with the view that low HDL-C contributes to elevated cardiovascular risk; genetic evidence is unclear however, potentially reflecting the complexity of HDL metabolism. The Panel believes that therapeutic targeting of elevated triglycerides (≥ 1.7 mmol/L or 150 mg/dL), a marker of TRL and their remnants, and/or low HDL-C (cardiovascular risk that persists in patients with cardiometabolic abnormalities at LDL-C goal.

    Full Text Available As treatment for HIV infection needs to be used continuously and lifelong, issues concerning long-term outcomes, including those involving tolerability and safety of treatment, are gaining increasing importance. Although current combination antiretroviral therapy (cART regimens are generally better tolerated than those in the early days of cART, treatment toxicity remains an important cause for discontinuation of (components of treatment. Moreover, several of the potential toxicities of cART (including cardiovascular, metabolic, renal and bone toxicity overlap with known ageing-associated co-morbidities. Given that our patient population with HIV is increasingly getting older as a result of the success of cART in reducing traditional HIV-associated morbidity and mortality, these co-morbidities are increasingly being seen and importantly influence patient management. Moreover, persons with HIV, in spite of having suppressed viraemia on cART seem to be at increased risk of the premature development of age-associated non-communicable co-morbidities, including cardiovascular, chronic kidney, liver and pulmonary disease, diabetes mellitus, osteoporosis, non-AIDS associated malignancies, and neurocognitive impairment. It has therefore been hypothesised that such individuals, despite effective cART, may be prone to accelerated ageing. The underlying pathogenesis is likely to be multifactorial and, apart from include sustained immune activation, both systemically and within the central nervous system. The presentation will review the current state of knowledge and investigation in this area.

We investigated the association of hs-cTnT with cognitive function and decline, and studied whether this association was independent....... Participants with pre-existent advanced clinical heart failure were excluded. Hs-cTnT and NT-proBNP obtained after 6 months of follow-up were related with cognitive function, tested repeatedly during a mean follow-up of 3.2 years. Participants with higher hs-cTnT performed worse at baseline on Stroop test...... diseases risk factors or Apolipoprotein E genotype. Further adjusting for NT-proBNP levels revealed the same results. CONCLUSIONS: Higher levels of hs-cTnT associate with worse cognitive function and steeper cognitive decline in older adults independent of cardiovascular diseases, risk factors and NT-proBNP....

    Full Text Available Objectives: Exercise improves endothelial dysfunction, the key manifestation of cardiovascular and cerebrovascular disease, and is recommended in both cardiovascular and cerebrovascular rehabilitation. Disagreement remains, however, on the role of intensity of exercise. The purpose of this review was to gather current knowledge on the effects of high-intensity training versus moderate-intensity continuous exercise on endothelial function in cardiovascular and cerebrovascular patients. Methods: A systematic review was performed in PubMed database, Embase and Cochrane libraries and on PEDro using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies were restricted to cardiovascular and cerebrovascular patients, and healthy subjects as general reference. Interventions comprised of high-intensity training alone, high-intensity training compared to moderate-intensity continuous exercise, or no training, with endothelial function as outcome measure. Endothelial function was measured either physiologically by flow-mediated dilatation and/or by systemic biomarkers. Data were analyzed descriptively due to non-comparability for a meta-analysis to be performed. Results: A total of 20 studies were included in the review. Although there was great heterogenecity in design, population and exercise protocols, all studies found high-intensity training to be safe. High-intensity training was equal to moderate-intensity continuous exercise through improvement in endothelial function in 15 of the 20 selected studies, as measured by flow-mediated dilatation, nitric oxide bioavailability and circulating biomarkers. Only a few studies examined high-intensity training in cerebrovascular patients, none with endothelial function as outcome. Conclusion: High-intensity training is promising as a time-efficient exercise strategy in cardiovascular rehabilitation, but data on endothelial effects in cerebrovascular rehabilitation are

    EMPA-REG OUTCOME is an international, prospective, placebo-controlled clinical trial investigating the cardiovascular outcomes of empagliflozin, an inhibitor of sodium-glucose cotransporters type 2 (SGLT2), in patients with type 2 diabetes mellitus and known cardiovascular disease. The trial succeeded in reaching the primary objective of non-inferiority and, in addition, showed, after a median follow up of 3.1 years, a superiority of empagliflozin (10 or 25 mg/day) versus placebo as regards the primary composite cardiovascular endpoint (hasard ratio or HR = 0.86; 95% CI 0.74-0.99; P = 0.04), hospitalisations for heart failure (-35%), cardiovascular mortality (-38%) and all-cause mortality (-32%, each p < 0.001). The reductionin mortality appeared early (< 6 months) and concerned all subgroups, without any obvious heterogeneity. This reduction in mortality does not seem to be fully explained by the concomitant slight reductions in HbA1c, body weight, waist circumference, blood pressure and serum uric acid levels in the empagliflozin groups versus the placebo group. Finally, the tolerance and safety profile of empagliflozin was good, with only a moderate increase in benign mycotic genital infections, a well-known adverse event with SGLT2 inhibitors. The remarkable effects of empagliflozin in the EMPA-REG OUTCOME trial, especially on mortality, should modify the management of patients with type 2 diabetes and a high cardiovascular risk in a near future.

    Control of lipid levels is one of the most effective strategies for cardiovascular (CV) event prevention. In fact, many clinical trials have clearly demonstrated that low-density lipoprotein cholesterol (LDL-C) lowering, primarily with statins, reduces major CV events and mortality. The evidence from these trials has been useful in designing the cholesterol treatment guidelines, which are mainly aimed at preventing and managing cardiovascular disease (CVD). However, available data indicate that a large proportion of patients fail to achieve lipid goals, and this is particularly frequent in patients at high or very high CV risk. Furthermore, owing to side effects, a significant percentage of patients cannot tolerate statin treatment. Hence, researchers have focused their attention on novel LDL-C-lowering agents that act via mechanisms distinct from that of statins. Among the new compounds under investigation, the monoclonal antibodies to proprotein convertase subtilisin/kexin type 9 (PCSK9) seem particularly promising, having recently been shown to be well tolerated and highly effective at lowering LDL-C, with a possible effect on the occurrence of CV events. Currently, alirocumab is approved by the US Food and Drug Administration (FDA) as an adjunct to diet and maximally tolerated statin therapy for use in adults with heterozygous familial hypercholesterolemia (FH) or those with atherosclerotic CV disease who require additional LDL-C lowering; it has also been recently approved by the European Medicines Agency (EMA) for use in patients with heterozygous FH, non-familial hypercholesterolemia or mixed dyslipidemia in whom statins are ineffective or not tolerated. Evolocumab is approved by the FDA as an adjunct to diet and maximally tolerated statins for adults with hetero- and homozygous FH and those with atherosclerotic CV disease who require additional lowering of LDL-C, and by the EMA in adults with primary hypercholesterolemia or mixed dyslipidemia, as an adjunct

Numerous clinical trials since the Framingham Study in 1977 have demonstrated an inverse relationship between HDL-C and one’s risk of developing CHD. Over the past two decades, preclinical research has gained further insight into the nature of HDL-C metabolism, specifically regarding the ability of HDL-C to promote reverse cholesterol transport (RCT. Recent attempts to harness HDL’s ability to enhance RCT have revealed the complexity of HDL-C metabolism. This review provides a detailed update on HDL-C as an evolving therapeutic target in the management of cardiovascular disease.Keywords: high density lipoprotein cholesterol (HDL-C, coronary, atherosclerosis, reverse cholesterol transport

    Full Text Available Patients with diabetes mellitus and symptomatic coronary artery disease are also likely to be hypertensive and, overall, are at very high cardiovascular (CV risk. This paper reports the findings of a posthoc analysis of the 1113 patients with diabetes mellitus in the ACTION trial: ACTION itself showed that outcomes in patients with stable angina and hypertension were significantly improved when a long-acting calcium channel blocking drug (nifedipine GITS was added to their treatment regimens. This further analysis of the ACTION database in those patients with diabetes has identified a number of practical therapeutic issues which are still relevant because of potential outcome benefits, particularly in relation to BP control. For example, despite background CV treatment and, specifically, despite the widespread use of ACE Inhibitor drugs, the addition of nifedipine GITS was associated with significant benefits: improvement in BP control by an average of 6/3 mmHg and significant improvements in outcome. In summary, this retrospective analysis has identified that the addition of nifedipine GITS resulted in improved BP control and significant outcome benefits in patients with diabetes who were at high CV risk. There is evidence to suggest that these findings are of direct relevance to current therapeutic practice.

    High-blood pressure is a powerful independent risk factor for death from heart disease and stroke. It is also a common clinical condition affecting more than 600 million persons worldwide and seen in nearly all populations. Although reliable, large-scale, population-based data on high blood pressure in sub-Saharan Africa (SSA) are limited, recent studies provide important and worrisome findings in both epidemiology and clinical outcomes. Although overall hypertension prevalence is between 10%-15%, prevalence rates as high as 30%-32% have been reported in middle-income urban and some rural areas. Importantly, hypertension awareness, treatment, and control rates as low as 20%, 10%, and 1%, respectively have also been found. Stroke has been by far the most common clinical sequela. In most SSA settings, hypertension control assumes a relatively low priority and little experience exists in implementing sustainable and successful programs for drug treatment. Rapid urbanization and transition from agrarian life to the wage-earning economy of city life continue to fuel increases in average blood pressure levels and prevalence of hypertension. Although the true burden of high blood pressure in sub-Saharan Africa remains largely unmeasured, compelling preliminary evidence suggests that it is the foundation for epidemic cardiovascular disease in Africa and already contributes substantively to death and disability from stroke, heart failure, and kidney failure in this region. Success in limiting this epidemic in SSA will depend heavily on the implementation of sustainable and aggressive population-based programs for high blood pressure awareness, prevention, treatment, and control. It will be critical to obtain investments in improved surveillance and program-relevant research to provide the evidence base for policy development and effective hypertension prevention and control.

    Full Text Available Increased seaweed consumption may be linked to the lower incidence of metabolic syndrome in eastern Asia. This study investigated the responses to two tropical green seaweeds, Ulva ohnoi (UO and Derbesia tenuissima (DT, in a rat model of human metabolic syndrome. Male Wistar rats (330–340 g were fed either a corn starch-rich diet or a high-carbohydrate, high-fat diet with 25% fructose in drinking water, for 16 weeks. High-carbohydrate, high-fat diet-fed rats showed the signs of metabolic syndrome leading to abdominal obesity, cardiovascular remodelling and non-alcoholic fatty liver disease. Food was supplemented with 5% dried UO or DT for the final 8 weeks only. UO lowered total final body fat mass by 24%, systolic blood pressure by 29 mmHg, and improved glucose utilisation and insulin sensitivity. In contrast, DT did not change total body fat mass but decreased plasma triglycerides by 38% and total cholesterol by 17%. UO contained 18.1% soluble fibre as part of 40.9% total fibre, and increased magnesium, while DT contained 23.4% total fibre, essentially as insoluble fibre. UO was more effective in reducing metabolic syndrome than DT, possibly due to the increased intake of soluble fibre and magnesium.

    Based on observational studies, there is a linear increase in cardiovascular risk with higher systolic blood pressure (SBP), yet clinical trials have not shown benefit across all SBP categories. We assessed whether troponin T measured using high-sensitivity assay was associated with cardiovascular disease within SBP categories in 11 191 Atherosclerosis Risk in Communities study participants. Rested sitting SBP by 10-mm Hg increments and troponin categories were identified. Incident heart failure hospitalization, coronary heart disease, and stroke were ascertained for a median of 12 years after excluding individuals with corresponding disease. Approximately 53% of each type of cardiovascular event occurred in individuals with SBPrisk compared with those with troponin T risk, particularly for heart failure. Individuals with lower SBP but measurable troponin T had greater cardiovascular risk compared with those with suboptimal SBP but undetectable troponin T. Future trials of systolic hypertension may benefit by using high-sensitivity troponin T to target high-risk patients. © 2014 American Heart Association, Inc.

    Full Text Available Obesity is a worldwide epidemic that is characterized not only by excessive fat deposition but also by systemic microinflammation, high oxidative stress, and increased cardiovascular risk factors. While diets enriched in natural antioxidants showed beneficial effects on oxidative stress, blood pressure, and serum lipid composition, diet supplementation with synthetic antioxidants showed contradictive results. Thus, we tested in C57Bl/6 mice whether a daily dosage of an antioxidative mixture consisting of vitamin C, vitamin E, L-arginine, eicosapentaenoic acid, and docosahexaenoic acid (corabion would affect cardiovascular risk factors associated with obesity. Obese mice showed increased serum triglyceride and glucose levels and hypertension after eight weeks of being fed a high-fat diet (HFD. Importantly, corabion ameliorated all of these symptoms significantly. Oxidative stress and early signs of systemic microinflammation already developed after two weeks of high-fat diet and were significantly reduced by daily doses of corabion. Of note, the beneficial effects of corabion could not be observed when applying its single antioxidative components suggesting that a combination of various nutrients is required to counteract HFD-induced cardiovascular risk factors. Thus, daily consumption of corabion may be beneficial for the management of obesity-related cardiovascular complications.

    Cardiovascular disease is the leading cause of death in developed countries. Among cardiovascular disease risk factors one of the most relevant is low-density lipoprotein-associated cholesterol (LDL-c), but there is controversy about the methods used to control it. The aim was to obtain an expert opinion to clarify the most relevant issues regarding the control of dyslipidemia in very high cardiovascular risk patients. A survey with 55 items, stratified into 4 blocks: LDL-c as a therapeutic target, therapeutic goals, causes of the failure to achieve LDL-c goals, and recommendations to optimize their achievement, was addressed to 41 specialists (Cardiology and Internal Medicine) using the Delphi method to achieve professional consensus criteria. A high consensus was reached among all items, in line with the European recommendations. The panelists considered that the goal of 70mg/dl for LDL-c for high cardiovascular disease risk (mainly vascular disease, diabetes mellitus, and renal failure), using combined treatment when necessary. Lack of adherence and therapeutic inertia were considered the main reasons for treatment failure. The Spanish experts show an elevated consensus with the European recommendations, confirming the LDL-c control target of <70mg/dl. The simplification of the guidelines and the combined treatment may favor an improvement the achievement of lipid target goals. Copyright © 2015 Sociedad Española de Arteriosclerosis.

Childrens Hospital of Zhejiang University School of Medicine, Hangzhou, China. Children from 6 years to 17 year old. 188 with simple obesity, and 431 with obesity and metabolic abnormalities. 274 age and gender-matched healthy children as controls. Receiver operating characteristic curves were used to analyze the detection of cardiovascular disease risk factors by cholesterol and triglyceride in children and adolescents. The ranges of areas under receiver operating characteristic curves (AUC) for triglyceride and non-high-density lipoprotein cholesterol were 0.798-0.860 and 0.667-0.749, respectively to detect cardiovascular disease risk factors. The ranges of AUC for low-density lipoprotein cholesterol, total cholesterol, and high-density lipoprotein cholesterol were 0.631-0.718, 0.596-0.683, and 0.292-0.376, respectively. Triglyceride and non-high-density lipoprotein cholesterol are better than low-density lipoprotein cholesterol as predictors of cardiovascular disease risk factors in Chinese Han children and adolescents.

    Full Text Available Abstract Background The assessment of arterial stiffness is increasingly used for evaluating patients with different cardiovascular diseases as the mechanical properties of major arteries are often altered. Aortic stiffness can be noninvasively estimated by measuring pulse wave velocity (PWV. Several methods have been proposed for measuring PWV using velocity-encoded cardiovascular magnetic resonance (CMR, including transit-time (TT, flow-area (QA, and cross-correlation (XC methods. However, assessment and comparison of these techniques at high field strength has not yet been performed. In this work, the TT, QA, and XC techniques were clinically tested at 3 Tesla and compared to each other. Methods Fifty cardiovascular patients and six volunteers were scanned to acquire the necessary images. The six volunteer scans were performed twice to test inter-scan reproducibility. Patient images were analyzed using the TT, XC, and QA methods to determine PWV. Two observers analyzed the images to determine inter-observer and intra-observer variabilities. The PWV measurements by the three methods were compared to each other to test inter-method variability. To illustrate the importance of PWV using CMR, the degree of aortic stiffness was assessed using PWV and related to LV dysfunction in five patients with diastolic heart failure patients and five matched volunteers. Results The inter-observer and intra-observer variability results showed no bias between the different techniques. The TT and XC results were more reproducible than the QA; the mean (SD inter-observer/intra-observer PWV differences were -0.12(1.3/-0.04(0.4 for TT, 0.2(1.3/0.09(0.9 for XC, and 0.6(1.6/0.2(1.4 m/s for QA methods, respectively. The correlation coefficients (r for the inter-observer/intra-observer comparisons were 0.94/0.99, 0.88/0.94, and 0.83/0.92 for the TT, XC, and QA methods, respectively. The inter-scan reproducibility results showed low variability between the repeated

    Morbid obesity alters drug dose requirement and time course of drug response. In addition, morbid obesity's impact on many organ systems decreases the margin of safety of anesthetic drugs. Consequently, incorrect dosing will increase the rate of perioperative complications. In this review, we will discuss factors that affect the pharmacokinetics and pharmacodynamics of anesthetic agents in the obese population, we specify certain dosing scalars, and we relate our current knowledge of obesity's effects on the clinical pharmacology of anesthetic drugs. A morbidly obese individual's increased cardiac output requires administration of higher drug doses than would be required for a standard-size person to attain the same peak-plasma concentration. Lean body weight (LBW) is highly correlated with the increased cardiac output, more so than fat mass or other variables. For most drugs, clearance increases nonlinearly with total body weight but linearly with LBW. Morbid obesity has no clinically significant impact on the uptake of the inhalation anesthetics isoflurane, sevoflurane, and desflurane when used in routine clinical practice. Total body weight dosing of neuromuscular blocking agents will result in a prolonged effect. For the induction dose of hypnotics and the initial dose of other drugs that have a fast onset of effect, cardiac output or LBW are relevant dosing scalars. For maintenance dosing, LBW seems to be a more appropriate dosing scalar than total body weight.

    Early mortality is high in hemodialysis (HD) patients, but little is known about early cardiovascular event (CVE) rates after HD initiation. To study this we analyzed data in the AROii cohort of incident HD patients from over 300 European Fresenius Medical Care dialysis centers. Weekly rates of a composite of CVEs during the first year and monthly rates of the composite and its constituents (coronary artery, cerebrovascular, peripheral arterial, congestive heart failure, and sudden cardiac death) during the first 2 years after HD initiation were assessed. Of 6308 patients that started dialysis within 7 days, 1449 patients experienced 2405 CVEs over the next 2 years. The first-year CVE rate (30.2/100 person-years; 95% CI, 28.7-31.7) greatly exceeded the second-year rate (19.4/100; 95% CI, 18.1-20.8). Composite CVEs were highest during the first week with increased risk compared with the second year, persisting until the fifth month. Except for sudden cardiac death, temporal patterns of rates for all CVE categories were very similar, with highest rates during the first month and a high-risk period extending to 4 months. Higher or lower cumulative weekly dialysis dose, lower blood flow, and lower net ultrafiltration during dialysis were associated with CVE during the high-risk period, but not during the post high-risk period. Thus, the incidence of CVE in the first weeks after HD initiation is much higher than during subsequent periods which raises concerns that HD initiation may trigger CVEs.

    Objective Concurrent low brain and high liver uptake are sometimes observed on fluorine-18-labeled fluoro-2-deoxy-D-glucose (FDG) positron emission tomography (PET). We investigated the potential clinical significance of this uptake pattern related to metabolic syndrome (MS). Materials and Methods We retrospectively reviewed data from 264 consecutive males who had undergone general health check-ups, including FDG PET/CT scans. After an overnight fast, the men had their peripheral blood drawn and the levels of various laboratory parameters measured; an FDG PET/CT scan was performed on the same day. We measured the maximum standardized uptake values of the brain and liver from regions of interest manually placed over the frontal cortex at the level of the centrum semiovale and the right lobe of the liver parenchyma, respectively. Results Fasting blood glucose (FBG; odds ratio [OR] = 1.063, p < 0.001) and glycated hemoglobin (HbA1c; OR = 3.634, p = 0.010) were the strongest predictive factors for low brain FDG uptake, whereas waist circumference (OR = 1.200, p < 0.001) and γ-glutamyl transpeptidase (OR = 1.012, p = 0.001) were the strongest predictive factors for high liver uptake. Eleven subjects (4.2%) showed concurrent low brain and high liver FDG uptake, and all but one of these subjects (90.9%) had MS. Systolic blood pressure, waist circumference, FBG, triglyceride, alanine aminotransferase, insulin resistance (measured by homeostasis model assessment), insulin, HbA1c, and body mass index were higher in subjects with this FDG uptake pattern than in those without (all, p < 0.001). Conclusion Concurrent low brain and high liver FDG uptake were closely associated with MS. Moreover, subjects with this pattern had higher values for various cardiovascular risk factors than did those without. PMID:28246520

    Context. The use of thiazolidinediones (TZDs) in patients with type-2 diabetes mellitus appears to be associated with an increased risk of myocardial infarction (MI) compared with placebo or other oral antidiabetic drug regimens. Objective. We conducted a study to investigate whether there was a difference in the risk of acute MI and hemorrhagic and non-hemorrhagic stroke between specific TZDs, namely rosiglitazone maleate (Avandia) and pioglitazone (Actos), and other oral antidiabetic agents in a high-risk, largely underrepresented and largely minority Medicaid population. Study Design, Setting, and Patients. We analyzed patient encounter data using propensity-scoring methods and logistic regression to compare the risk of cardiovascular (CV) events in patients with type-2 diabetes in a high-risk population. Main Outcome Measures. Outcomes were identified through International Classification of Disease (ICD-9) codes 410–411 for acute MI; 430–438 for stroke; and revenue (emergency department) codes 450–459 in the case of MI. Results. Using retrospective medical encounter and prescription data analyses, we found that rosiglitazone, compared with other oral antidiabetic agents, was associated with an increased rate of CV events by 20% in a high-risk cohort of diabetic patients. Neither pioglitazone nor the TZD drug class as a whole was associated with an increased CV risk. Conclusion. Rosiglitazone was associated with a significant increase in CV events (MI and stroke) among high-risk patients with type-2 diabetes, whereas pioglitazone was not. We recommend further research to capture risk factors that were not observed in our encounter data. PMID:20140111

    Full Text Available Obesity is a chronic disease, whose incidence is alarmingly growing. It is associated with metabolic abnormalities and cardiovascular complications. These complications are clustered in the metabolic syndrome (MetS leading to high cardiovascular morbidity and mortality. Obesity predisposes to diabetic nephropathy, hypertensive nephrosclerosis, and focal and segmental glomerular sclerosis and represents an independent risk factor for the development and progression of chronic kidney disease (CKD. Albuminuria is a major risk factor for cardiovascular diseases (CVDs. Microalbuminuria has been described as early manifestation of MetS-associated kidney damage and diabetic nephropathy. Obesity and MetS affect renal physiology and metabolism through mechanisms which include altered levels of adipokines such as leptin and adiponectin, oxidative stress, and inflammation. Secretory products of adipose tissue also deeply and negatively influence endothelial function. A better understanding of these interactions will help in designing more effective treatments aimed to protect both renal and cardiovascular systems.

    Full Text Available Objective: One of the practical models for assessment of stressful working conditions due to job strain is "job demand and control" or Karasek's job strain model. This model explains how adverse physical and psychological effects including cardiovascular disease risk factors can be established due to high work demand. The aim was to investigate how certain cardiovascular risk factors including body mass index (BMI, heart rate, blood pressure, serum total cholesterol levels, and cigarette smoking are associated with job demand and control in workers. Materials and Methods: In this cohort study, 500 subjects completed "job demand and control" questionnaires. Factor analysis method was used in order to specify the most important "job demand and control" questions. Health check-up records of the workers were applied to extract data about cardiovascular disease risk factors. Ultimately, hypothesis testing, based on Eta, was used to assess the relationship between separated working groups and cardiovascular risk factors (hypertension and serum total cholesterol level. Results: A significant relationship was found between the job demand-control model and cardiovascular risk factors. In terms of chisquared test results, the highest value was assessed for heart rate (Chi2 = 145.078. The corresponding results for smoking and BMI were Chi2 = 85.652 and Chi2 = 30.941, respectively. Subsequently, Eta result for total cholesterol was 0.469, followed by hypertension equaling 0.684. Moreover, there was a significant difference between cardiovascular risk factors and job demand-control profiles among different working groups including the operational group, repairing group and servicing group. Conclusion: Job control and demand are significantly related to heart disease risk factors including hypertension, hyperlipidemia, and cigarette smoking.

    Obesity is a global epidemic leading to several comorbidities including diabetes and cardiovascular disease. The hypothesis that the genetic background of the obesity-prone rat (OP) predisposes to physiologic, metabolic, and microvascular dysfunction which is exacerbated by a diet high in saturated fats was tested. Male OP and obesity-resistant (OR) rats were fed either a diet containing 10% (chow) or 45% kcal fat (HF) for 42 weeks. Weight of OP rats was greater than OR rats by 8 weeks on both diets. Blood pressure was increased in OP rats on chow and further augmented by HF diet compared to OR rats on similar diets. In contrast to weight and blood pressure, glucose clearance was similar in OR and OP rats on chow and impaired in both models on HF diet. Relaxation to acetylcholine was attenuated in OP rats compared to OR rats by 8 weeks and remained reduced throughout the study. A longer period of time was required to observe vascular dysfunction in HF-fed OR rats. When compared to OR rats, OP rats are prone to develop not only greater obesity but also hypertension and vascular dysfunction on a normal diet which is further augmented with HF diet. © 2015 The Obesity Society.

    Erectile dysfunction (ED) is associated with cardiovascular risk factors as elevated systolic blood pressure (SBP), resting high heart rate (HR), and endothelial dysfunction and predicts cardiovascular events. However, the interaction between high HR and SBP and the development of ED remains unclear. We evaluated 1015 male patients enrolled in the ED substudy of ONTARGET and TRANSCEND, examining the influence of mean HR and mean SBP obtained over all study visits (mean 10.9±1.4 study visits) and their interaction with ED. In patients without pre-existing ED, new onset ED was detected in 29% of patients below, and 41% of patients above, the median of mean HR (OR 1.72, 95% CI 1.8-2.5, p = 0.0047). In patients with pre-existing ED, high HR had no add-on effect. With or without pre-existing ED, high SBP had no influence after adjustment for covariates (OR 1.03, 95% CI 0.66-1.59, p = 0.91). In a continuous model, it was shown that effects of high HR were prominent at low Kölner (Cologne) Evaluation of Erectile Function (KEED) score baseline values and in the presence of SBP above the median. In patients at risk for cardiovascular events, high HR is associated with ED, whereas the effect of high SBP was not significant. High resting HR might represent a cardiovascular risk indicator. Whether HR represents a potential treatment target to improve ED in high-risk individuals must be scrutinized in prospective trials.

    Cardiovascular atherothrombosis is the most common cause of death globally, with several well-known risk factors. Air pollution is a byproduct of fuel combustion by motor vehicles, power plants and industrial factories. It is composed of gases, fluids and particulate matter (PM) of different sizes, which include basic carbon, organic carbonic molecules and metals such as vanadium, nickel, zinc and iron. These particles are subdivided by their median size, a major contributing factor for their capability to enter the human body through the respiratory system. Most of the epidemiological studies have shown correlation between acute and long-term exposure to air pollution elements and cardiovascular morbidity in general, and angina pectoris and acute myocardial infarction specifically. Physiological studies have found different arrhythmias as the etiologic cause of cardiovascular morbidity and mortality following exposure to air pollution. A major finding was a decline in heart rate variability, a phenomenon known as endangering for cardiovascular morbidity and mortality, especially in patients after acute myocardial infarction. To date, several pathways have been proposed, including a hypercoagulable state following an inflammatory response, cardiac nervous autonomic disequilibrium, endothelial dysfunction with blood vessel contraction and direct toxic impact on cardiac muscle. Additional research is needed for clarifying the pathophysiological pathways by which air pollution affects the cardiovascular system. That might allow forthcoming with preventive measures and correct treatment, and hence a decrease in cardiovascular morbidity and mortality. Another important target is dose-outcome correlation curves for safety threshold calculation as a basis for air pollution regulations.

    The role of exercise training in the prevention and treatment of type 2 diabetes mellitus has been studied extensively over the past two decades. Although the primary treatment aim for patients with type 2 diabetes is metabolic control, the morbidity and mortality associated with the disease is more a function of cardiovascular disease. As exercise is associated with favourable reductions in the risk for cardiovascular disease in other high-risk populations, here we explore the role of exercise in the treatment of cardiovascular maladaptations associated with type 2 diabetes. The cardiovascular adaptation to type 2 diabetes is characterised by hypertrophy, stiffening and loss of functional reserve. Clinically, the cardiovascular adaptations to the diabetic state are associated with an increased risk for cardiovascular disease. Functionally, these adaptations have been shown to contribute to a reduced exercise capacity, which may explain the reduced cardiovascular fitness observed in this population. Exercise training is associated with improved exercise capacity in various populations, including type 2 diabetes. Several structural and functional adaptations within the cardiovascular system following exercise training could explain these findings, such as reductions in ventricular and vascular structural hypertrophy and compliance coupled with increased functional reserve. Although these cardiovascular adaptations to aerobic exercise training have been well documented in older populations with similar decrements in cardiovascular fitness and function, they have yet to be examined in patients with type 2 diabetes. For this reason, we contend that exercise training may be an excellent therapeutic adjunct in the treatment of diabetic cardiovascular disease.

    This study aimed at examining the autonomic cardiovascular modulation in well-trained masters and young cyclists following high-intensity interval training (HIT). Nine masters (age 55.6 ± 5.0 years) and eight young cyclists (age 25.9 ± 3.0 years) completed a HIT protocol of 6 x 30 sec at 175% of peak power output, with 4.5-min' rest between efforts. Immediately following HIT, heart rate and R-R intervals were monitored for 30-min during passive supine recovery. Autonomic modulation was examined by i) heart rate recovery in the first 60-sec of recovery (HRR60); ii) the time constant of the 30-min heart rate recovery curve (HRRτ); iii) the time course of the root mean square for successive 30-sec R-R interval (RMSSD30); and iv) time and frequency domain analyses of subsequent 5-min R-R interval segments. No significant between-group differences were observed for HRR60 (P = 0.096) or HRRτ (P = 0.617). However, a significant interaction effect was found for RMSSD30 (P = 0.021), with the master cyclists showing higher RMSSD30 values following HIT. Similar results were observed in the time and frequency domain analyses with significant interaction effects found for the natural logarithm of the RMSSD (P = 0.008), normalised low-frequency power (P = 0.016) and natural logarithm of high-frequency power (P = 0.012). Following high-intensity interval training, master cyclists demonstrated greater post-exercise parasympathetic reactivation compared to young cyclists, indicating that physical training at older ages has significant effects on autonomic function.

    2016-01-01

    Introduction: Chronic noncommunicable diseases (NCDs) including cardiovascular diseases (CVDs) are the leading cause of death in the world, and their incidence is rising rapidly due to increasing rates of risk factors such as hypertension, dyslipidemia, diabetes, obesity, physical inactivity, and tobacco use. These risk factors track from childhood to adulthood, and their distribution varies among males and females; hence, there is a need to determine risk factor prevalence among adolescent age group so as to plan preventive strategies. Objective: To determine the distribution of risk factors of CVDs amongst high school boys and girls of urban Dibrugarh, Assam. Subjects and Methods: A cross-sectional study was conducted from October 2012 to June 2013 in the schools of urban Dibrugarh, Assam wherein data was collected from 1000 students of Class 8–10 using multistage random sampling and risk factors were assessed using WHO steps methodology. Statistical Analysis: Statistical analysis was done using SPSS 16 software and test of differences used were Chi-square test and t-test. Results: The prevalence of ever tobacco use was 32.3% among boys and 6.6% among girls (P < 0.001) while ever alcohol use was reported by 11.9% boys and 1% girls (P < 0.001). Prevalence of overweight and hypertension was found to be higher among girls (11.7% and 24.1%) as compared to boys (6.8% and 18.1%). Prevalence of hypercholesterolemia was higher among boys while high triglycerides levels were more prevalent among girls. Conclusion: The study revealed a high prevalence of various risk factors among boys and girls. There is a need to reduce the risk factor prevalence of CVD among this group of the population to address the future epidemic of NCD. Different health promotional activities need to be implemented to target boys and girls as the risk factor distribution among these groups is different. PMID:27453853

    Full Text Available BACKGROUND: Adherence to the Mediterranean diet (MD is associated with reduced morbidity and mortality due to cardiovascular disease. However, how the MD exerts its effects is not fully known. AIM: To assess the 12-month effects of two enhanced MDs compared to a low-fat diet on inflammatory biomarkers related to atherosclerosis and plaque vulnerability in a subcohort of the PREDIMED (Prevención con Dieta Mediterránea study. METHODS: A total of 164 participants at high risk for cardiovascular disease were randomized into three diet groups: MD supplemented with 50mL/d of extra virgin olive oil (MD+EVOO or 30 g/d of nuts (MD+Nuts and a low-fat diet. Changes in classical cardiovascular risk factors, inflammatory biomarkers of atherosclerosis and plaque vulnerability were measured after 12 months of intervention. RESULTS: Compared to participants in the low-fat diet group, those receiving MD+EVOO and MD+Nuts showed a higher decrease in systolic (6mmHg and diastolic (3mmHg blood pressure (P = 0.02; both, as well as a reduction of 10% and 8% in LDL-cholesterol (P = 0.04, respectively. Patients in the MD+Nuts group showed a significant reduction of 34% in CD40 expression on monocyte surface compared to low-fat diet patients (P = 0.03. In addition, inflammatory biomarkers related to plaque instability such as C-reactive protein and interleukin-6 were reduced by 45% and 35% and 95% and 90% in the MD+EVOO and MD+Nuts groups, respectively (P<0.05; all compared to the low-fat diet group. Likewise, sICAM and P-selectin were also reduced by 50% and 27%, respectively in the MD+EVOO group (P = 0.04 and P-selectin by 19% in MD+Nuts group (P = 0.04 compared to the low-fat diet group. CONCLUSIONS: Adherence to the MD is associated with an increase in serum markers of atheroma plaque stability which may explain, at least in part, the protective role of MD against ischemic heart disease.

    Dietary fat quality and fat replacement are more important for cardiovascular disease (CVD) prevention than is total dietary fat intake. The aim was to evaluate the association between total fat intake and fat subtypes with the risk of CVD (myocardial infarction, stroke, or death from cardiovascular causes) and cardiovascular and all-cause death. We also examined the hypothetical effect of the isocaloric substitution of one macronutrient for another. We prospectively studied 7038 participants at high CVD risk from the PREvención con DIeta MEDiterránea (PREDIMED) study. The trial was conducted from 2003 to 2010, but the present analysis was based on an expanded follow-up until 2012. At baseline and yearly thereafter, total and specific fat subtypes were repeatedly measured by using validated food-frequency questionnaires. Time-dependent Cox proportional hazards models were used. After 6 y of follow-up, we documented 336 CVD cases and 414 total deaths. HRs (95% CIs) for CVD for those in the highest quintile of total fat, monounsaturated fatty acid (MUFA), and polyunsaturated fatty acid (PUFA) intake compared with those in the lowest quintile were 0.58 (0.39, 0.86), 0.50 (0.31, 0.81), and 0.68 (0.48, 0.96), respectively. In the comparison between extreme quintiles, higher saturated fatty acid (SFA) and trans-fat intakes were associated with 81% (HR: 1.81; 95% CI: 1.05, 3.13) and 67% (HR: 1.67; 95% CI: 1.09, 2.57) higher risk of CVD. Inverse associations with all-cause death were also observed for PUFA and MUFA intakes. Isocaloric replacements of SFAs with MUFAs and PUFAs or trans fat with MUFAs were associated with a lower risk of CVD. SFAs from pastries and processed foods were associated with a higher risk of CVD. Intakes of MUFAs and PUFAs were associated with a lower risk of CVD and death, whereas SFA and trans-fat intakes were associated with a higher risk of CVD. The replacement of SFAs with MUFAs and PUFAs or of trans fat with MUFAs was inversely associated

The dexmedetomidine, an alpha 2-adrenergic agonist, has appeared as an adjuvant option of the venous anesthesia technique. This study aimed at assessing the efficacy of dexmedetomidine associated with the venous anesthesia in morbid obese patients undergoing gastroplasty procedures. METHODS: Retrospective analysis of morbid obese patients undergone open bariatric surgical intervention under anesthesia with propofol and alfentanil, with or without dexmedetomidine. Patients were allocated into two groups: Control (propofol and alfentanil and Dexmedetomidine (propofol, alfentanil and dexmedetomidine. For both groups, the anesthetic maintenance was as follows: propofol = 0.075 to 0.1 mg.kg-1.min-1 and alfentanil = 0.75 to 1 µg.kg-1.min-1; in the dexmedetomidine (DMD group, initial dose of 1 µg.kg-1 in 10 min and maintenance with 0.4 to 0.7 µg.kg-1.h-1. The variables studied were: age, gender, body mass index (BMI, surgical time and recovery time, heart rate (HR, systolic and diastolic blood pressure (SBP and DBP, hemoglobin peripheral saturation (SpO-2, propofol and alfentanil consumption and side effects. RESULTS: The dexmedetomidine group has shown a significant reduction in propofol and alfentanil consumption. The heart rate presented a significant variation only in the dexmedetomidine group. Both SPB and DBP presented a statistically significant reduction in both groups for the first 20 minutes, and subsequent stabilization. No side effects were observed in both groups of patients. CONCLUSIONS: This study has shown the efficacy of dexmedetomidine administration in combination with venous anesthesia with

    Background Vitamin D deficiency is a major global public health problem. Recent epidemiological studies have assessed the relationship between vitamin D and multiple outcomes, including cardiovascular disease. However, this evidence is limited and inconclusive. Our purpose in this study was to evaluate the association between dietary vitamin D intake and cardiovascular disease risk in adult Mexican population. Methods We conducted a cross-sectional analysis with the baseline data from 6294 men and women aged 20–80 years participating in the Health Workers Cohort Study. Data on sociodemographic, lifestyle, and medical history factors were collected with a self-administered questionnaire. Dietary intake was evaluated by using a semi-quantitative food-frequency questionnaire. Cardiovascular disease risk was calculated using a recalibration of the Framingham heart disease prediction score. To evaluate the association between vitamin D intake and 10-year cardiovascular disease risk, odds ratios (OR) and 95% confidence intervals (95% CI) were calculated using multiple logistic regression analysis. Results A total of 6294 subjects (1820 men and 4474 women) with a mean age of 42 years, were included. Of these, subjects in the highest quintile of vitamin D intake presented lower levels of triglycerides 14.6 mg/dL (P for trend = 0.001); 2.0 cm less in waist circumference (P for trend = 0.001) and 0.8 points less in the Framingham cardiovascular disease risk score (P for trend = 0.002) compared with the subjects in the lower quintile of vitamin D intake. Additionally, participants in the highest quintile of vitamin D consumption were less likely to develop elevated 10-year cardiovascular disease risk, compared with those in the lowest quintile (OR = 0.51; 95%CI: 0.33, 0.77; P for trend = 0.007). Conclusion Our data suggest that higher consumption of vitamin D is associated with a reduced risk of cardiovascular disease in Mexican population. PMID:27893863

    Pseudoexfoliation(PEX) syndrome is a well-recognized late-onset disease caused by a generalized fibrillopathy. It is linked to a broad spectrum of ocular complications including glaucoma and perioperative problems during cataract surgery. Apart from the long-known intraocular manifestations, PEX deposits have been found in a variety of extraocular locations and they appear to represent a systemic process associated with increased cardiovascular and cerebrovascular morbidity. However, as published results are inconsistent, the clinical significance of the extraocular PEX deposits remains controversial. Identification of PEX deposits in the heart and the vessel wall, epidemiologic studies, as well as, similarities in pathogenetic mechanisms have led to the hypothesis of a possible relation between fibrillar material and cardiovascular disease. Recent studies suggest that PEX syndrome is frequently linked to impaired heart and blood vessels function. Systemic and ocular blood flow changes, altered parasympathetic vascular control and baroreflex sensitivity, increased vascular resistance and decreased blood flow velocity, arterial endothelial dysfunction, high levels of plasma homocysteine and arterial hypertension have all been demonstrated in PEX subjects. Common features in the pathogenesis of both atherosclerosis and PEX, like oxidative stress and inflammation and a possible higher frequency of abdominal aorta aneurysm in PEX patients, could imply that these grey-white deposits and cardiovascular disorders are related or reflect different manifestations of the same process.

    Air pollution is associated with increased cardiovascular morbidity and mortality. Recent experimental and epidemiologic studies show that particulate matter (PM) air pollution with PM10 or inhalable (thoracic) particles (mean aerodynamic diameter particles (aerodynamic diameter biological mechanisms responsible for adverse cardiovascular outcomes associated with PM have been described, including the release of pro-oxidative and pro-inflammatory mediators from the lungs into the circulation, autonomic nervous system imbalance, and the direct actions on the heart and vasculature of ultrafine particles translocated into the systemic circulation. The induction of oxidative stress by these particles may be central to all of these putative pathways that trigger coagulation and thrombosis, increased heart rate and reduced heart rate variability, endothelial dysfunction, arterial vasoconstriction, apoptosis, and hypertension. In chronic exposures these alterations favor the development and progression of atherosclerosis and possibly of hypertension in the long term, and in the short term acute exposures contribute to plaque instability, affect various traditional risk factors and trigger acute cardiovascular events (myocardial ischemia and infarction, stroke, heart failure, arrhythmias, and sudden death), particularly in high-risk subjects. There are currently also significant concerns with the risks of engineered nanoparticles.

    Full Text Available The aim of this study was to evaluate the involvement of nitric oxide (NO system damage in the deleterious effects of high-fructose intake in rats. Fructose was administered as 10% solution in drinking water to twelve-week-old male Wistar rats for the period of 8 weeks. Blood pressure was measured by tail-cuff plethysmography. After sacrificing the rats at the end of the treatment, relative weights of heart and liver and biochemical parameters in blood plasma were determined. Reactivity of isolated conduit arteries was measured using a force-displacement transducer for recording isometric tension. Fructose drinking rats had increased blood pressure and impaired acetylcholine-induced relaxation of the thoracic aorta in comparison with control rats drinking just tap water. Relative liver weight and plasma concentrations of glucose and triglycerides were also elevated after fructose administration. In a further group of Wistar rats, inhibition of NO production by administration of NG-nitro-L-arginine methyl ester (L-NAME; 40 mg/kg/day was performed throughout fructose intake. L-NAME treatment itself induces increase in blood pressure and relative heart weight as well as impairment in arterial relaxation and contractility. However, in these rats, fructose administration did not cause further elevation of blood pressure and other abnormalities observed in rats receiving fructose without L-NAME. Our results showed that in the state of NO deficiency (induced by L-NAME administration fructose does not induce cardiovascular and metabolic alterations which develop in rats with a functional NO system. This indicates that impairment of the NO system may participate in many of the adverse effects induced by high-fructose intake.

    The transmission of overweight from one generation to the next is well established, however little is known about what psychosocial factors may protect against this familial risk. The aim of this study was to examine whether optimism plays a role in the intergenerational transmission of obesity. Our sample included 1043 participants from the prospective Cardiovascular Risk in Young FINNS Study. Optimism was measured in early adulthood (2001) when the cohort was aged 24-39years. BMI was measured in 2001 (baseline) and 2012 when they were aged 35-50years. Parental BMI was measured in 1980. Hierarchical linear regression and logistic regression were used to examine the association between optimism and future BMI/obesity, and whether an interaction existed between optimism and parental BMI when predicting BMI/obesity 11years later. High optimism in young adulthood demonstrated a negative relationship with high BMI in mid-adulthood, but only in women (β=-0.127, p=0.001). The optimism×maternal BMI interaction term was a significant predictor of future BMI in women (β=-0.588, p=0.036). The logistic regression results confirmed that high optimism predicted reduced obesity in women (OR=0.68, 95% CI, 0.55-0.86), however the optimism × maternal obesity interaction term was not a significant predictor (OR=0.50, 95% CI, 0.10-2.48). Our findings supported our hypothesis that high optimism mitigated the intergenerational transmission of high BMI, but only in women. These findings also provided evidence that positive psychosocial factors such as optimism are associated with long-term protective effects on BMI in women. Copyright © 2017 Elsevier Inc.

  16. High-Intensity Interval Training Versus Moderate-Intensity Continuous Training in the Prevention/Management of Cardiovascular Disease.

    Science.gov (United States)

    Hussain, Syed R; Macaluso, Andrea; Pearson, Stephen J

    Moderate-intensity continuous training (MICT) has long been considered the most effective exercise treatment modality for the prevention and management of cardiovascular disease (CVD), but more recently high-intensity interval training (HIIT) has been viewed as a potential alternative to MICT in accruing such benefits. HIIT was initially found to induce significant improvements in numerous physiological and health-related indices, to a similar if not superior extent to MICT. Since then, many studies have attempted to explore the potential clinical utility of HIIT, relative to MICT, with respect to treating numerous cardiovascular conditions, such as coronary artery disease, heart failure, stroke, and hypertension. Despite this, however, the efficacy of HIIT in reversing the specific symptoms and risk factors of these cardiovascular pathologies is not well understood. HIIT is often perceived as very strenuous, which could render it unsafe for those at risk of or afflicted with CVD, but these issues are also yet to be reviewed. Furthermore, the optimal HIIT protocol for each of the CVD cohorts has not been established. Thus, the purpose of this review article is to (1) evaluate the efficacy of HIIT relative to MICT in the prevention and management of cardiovascular conditions, and (2) explore any potential safety issues surrounding the suitability and/or tolerability of HIIT for patients with CVD, and the potential optimal prescriptive variables of HIIT for application in the clinical environment.

    Full Text Available Abstract Introduction Adenosine is the most widely used vasodilator stress agent for Cardiovascular Magnetic Resonance (CMR perfusion studies. With the standard dose of 140 mcg/kg/min some patients fail to demonstrate characteristic haemodynamic changes: a significant increase in heart rate (HR and mild decrease in systolic blood pressure (SBP. Whether an increase in the rate of adenosine infusion would improve peripheral and, likely, coronary vasodilatation in those patients is unknown. The aim of the present study was to assess the tolerance and safety of a high-dose adenosine protocol in patients with inadequate haemodynamic response to the standard adenosine protocol when undergoing CMR perfusion imaging. Methods 98 consecutive patients with known or suspected coronary artery disease (CAD underwent CMR perfusion imaging at 1.5 Tesla. Subjects were screened for contraindications to adenosine, and an electrocardiogram was performed prior to the scan. All patients initially received the standard adenosine protocol (140 mcg/kg/min for at least 3 minutes. If the haemodynamic response was inadequate (HR increase Results All patients successfully completed the CMR scan. Of a total of 98 patients, 18 (18% did not demonstrate evidence of a significant increase in HR or decrease in SBP under the standard adenosine infusion rate. Following the increase in the rate of infusion, 16 out of those 18 patients showed an adequate haemodynamic response. One patient of the standard infusion group and two patients of the high-dose group developed transient advanced AV block. Significantly more patients complained of chest pain in the high-dose group (61% vs. 29%, p = 0.009. On multivariate analysis, age > 65 years and ejection fraction Conclusions A substantial number of patients do not show adequate peripheral haemodynamic response to standard-dose adenosine stress during perfusion CMR imaging. Age and reduced ejection fraction are predictors of inadequate

    Although previous studies have analyzed the association between cardiovascular risk factors and blood pressure in adolescents, few studies conducted in developing countries analyzed whether the aggregation of risk factors contributes to an increased risk of high blood pressure in adolescents. The objective of this study was to assess the association between cardiovascular risk factors (including general overweight, abdominal obesity, high consumption of foods rich in fats, and insufficient physical activity levels) and high blood pressure in adolescents. This study was carried out from 2007 to 2008 with 1021 adolescents (528 girls) from primary schools located in the city of Londrina- Brazil. Blood pressure was assessed using an oscillometric device. General overweight was obtained through body mass index, abdominal obesity was assessed using waist circumference, and the consumption of foods rich in fat and physical activity were assessed using a questionnaire. The sum of these risk factors was determined. Adolescents with three or four aggregated risk factors were more likely to have higher values of systolic and diastolic blood pressure when compared with adolescents who did not have any cardiovascular risk factors (P = 0.001 for both). Logistic regression indicated that groups of adolescents with 2 (OR= 2.46 [1.11-5.42]; P = 0.026), 3 (OR= 4.97 [2.07-11.92]; P = 0.001) or 4 risk factors (OR= 6.79 [2.24-19.9]; P = 0.001) presented an increased likelihood of high blood pressure. The number of cardiovascular risk factors was found to be related to high blood pressure in adolescents. Copyright © 2014 Wiley Periodicals, Inc.

    The purpose of this study was to examine the effects of short-term high-intensity interval training (HIIT) on cardiovascular function, cardiorespiratory fitness, and muscular force. Active, young (age and body fat = 25.3 ± 4.5 years and 14.3 ± 6.4%) men and women (N = 20) of a similar age, physical activity, and maximal oxygen uptake (VO2max) completed 6 sessions of HIIT consisting of repeated Wingate tests over a 2- to 3-week period. Subjects completed 4 Wingate tests on days 1 and 2, 5 on days 3 and 4, and 6 on days 5 and 6. A control group of 9 men and women (age and body fat = 22.8 ± 2.8 years and 15.2 ± 6.9%) completed all testing but did not perform HIIT. Changes in resting blood pressure (BP) and heart rate (HR), VO2max, body composition, oxygen (O2) pulse, peak, mean, and minimum power output, fatigue index, and voluntary force production of the knee flexors and extensors were examined pretraining and posttraining. Results showed significant (p VO2max, O2 pulse, and Wingate-derived power output with HIIT. The magnitude of improvement in VO2max was related to baseline VO2max (r = -0.44, p = 0.05) and fatigue index (r = 0.50, p 0.05) in resting BP, HR, or force production was revealed. Data show that HIIT significantly enhanced VO2max and O2 pulse and power output in active men and women.

  4. Residual Cardiovascular Risk in Chronic Kidney Disease: Role of High-density Lipoprotein

    Kon, Valentina; Yang, Haichun; Fazio, Sergio

    2016-01-01

    Although reducing low-density lipoprotein-cholesterol (LDL-C) levels with lipid-lowering agents (statins) decreases cardiovascular disease (CVD) risk, a substantial residual risk (up to 70% of baseline) remains after treatment in most patient populations. High-density lipoprotein (HDL) is a potential contributor to residual risk, and low HDL-cholesterol (HDL-C) is an established risk factor for CVD. However, in contrast to conventional lipid-lowering therapies, recent studies show that pharmacologic increases in HDL-C levels do not bring about clinical benefits. These observations have given rise to the concept of dysfunctional HDL where increases in serum HDL-C may not be beneficial because HDL loss of function is not corrected by or even intensified by the therapy. Chronic kidney disease (CKD) increases CVD risk, and patients whose CKD progresses to end-stage renal disease (ESRD) requiring dialysis are at the highest CVD risk of any patient type studied. The ESRD population is also unique in its lack of significant benefit from standard lipid-lowering interventions. Recent studies indicate that HDL-C levels do not predict CVD in the CKD population. Moreover, CKD profoundly alters metabolism and composition of HDL particles and impairs their protective effects on functions such as cellular cholesterol efflux, endothelial protection, and control of inflammation and oxidation. Thus, CKD-induced perturbations in HDL may contribute to the excess CVD in CKD patients. Understanding the mechanisms of vascular protection in renal disease can present new therapeutic targets for intervention in this population. PMID:26009251

    This study updates information on mortality and cancer morbidity in a cohort of Norwegian talc workers. Follow-up was extended with 24 years, covering 1953-2011. Comparisons were made with the general population and between subgroups within the cohort. Standardized mortality ratio for non-malignant respiratory disease (NMRD) was 0.38 (95%CI: 0.18, 0.69) and for diseases of the circulatory system (CVD) 0.98 (95%CI: 0.82, 1.16). A non-significantly increased NMRD risk was observed at high dust exposures. There were no deaths from pneumoconiosis. With the clear limitations of a small cohort, our results do hint at an effect of talc dust on mortality from NMRD other than pneumoconiosis, covered by a strong and persisting healthy worker effect. Also, an effect on CVD mortality, masked by a healthy worker selection into the cohort cannot be ruled out. Excess mortality from pneumoconiosis seen in other studies, may reflect exposure to quartz and, possibly, bias due to comparability problems. © 2017 Wiley Periodicals, Inc.

  8. Ozone and cardiovascular injury

    2009-06-01

    Full Text Available Abstract Air pollution is increasingly recognized as an important and modifiable determinant of cardiovascular diseases in urban communities. The potential detrimental effects are both acute and chronic having a strong impact on morbidity and mortality. The acute exposure to pollutants has been linked to adverse cardiovascular events such as myocardial infarction, heart failure and life-threatening arrhythmias. The long-terms effects are related to the lifetime risk of death from cardiac causes. The WHO estimates that air pollution is responsible for 3 million premature deaths each year. The evidence supporting these data is very strong nonetheless, epidemiologic and observational data have the main limitation of imprecise measurements. Moreover, the lack of clinical experimental models makes it difficult to demonstrate the individual risk. The other limitation is related to the lack of a clear mechanism explaining the effects of pollution on cardiovascular mortality. In the present review we will explore the epidemiological, clinical and experimental evidence of the effects of ozone on cardiovascular diseases. The pathophysiologic consequences of air pollutant exposures have been extensively investigated in pulmonary systems, and it is clear that some of the major components of air pollution (e.g. ozone and particulate matter can initiate and exacerbate lung disease in humans 1. It is possible that pulmonary oxidant stress mediated by particulate matter and/or ozone (O3 exposure can result in downstream perturbations in the cardiovasculature, as the pulmonary and cardiovascular systems are intricately associated, and it is well documented that specific environmental toxins (such as tobacco smoke 2 introduced through the lungs can initiate and/or accelerate cardiovascular disease development. Indeed, several epidemiologic studies have proved that there is an association between PM and O3 and the increased incidence of cardiovascular morbidity

    Even at low-density lipoprotein cholesterol (LDL-C) goal, patients with cardiometabolic abnormalities remain at high risk of cardiovascular events. This paper aims (i) to critically appraise evidence for elevated levels of triglyceride-rich lipoproteins (TRLs) and low levels of high-density lipoprotein cholesterol (HDL-C) as cardiovascular risk factors, and (ii) to advise on therapeutic strategies for management. Current evidence supports a causal association between elevated TRL and their remnants, low HDL-C, and cardiovascular risk. This interpretation is based on mechanistic and genetic studies for TRL and remnants, together with the epidemiological data suggestive of the association for circulating triglycerides and cardiovascular disease. For HDL, epidemiological, mechanistic, and clinical intervention data are consistent with the view that low HDL-C contributes to elevated cardiovascular risk; genetic evidence is unclear however, potentially reflecting the complexity of HDL metabolism. The Panel believes that therapeutic targeting of elevated triglycerides (≥1.7 mmol/L or 150 mg/dL), a marker of TRL and their remnants, and/or low HDL-C (<1.0 mmol/L or 40 mg/dL) may provide further benefit. The first step should be lifestyle interventions together with consideration of compliance with pharmacotherapy and secondary causes of dyslipidaemia. If inadequately corrected, adding niacin or a fibrate, or intensifying LDL-C lowering therapy may be considered. Treatment decisions regarding statin combination therapy should take into account relevant safety concerns, i.e. the risk of elevation of blood glucose, uric acid or liver enzymes with niacin, and myopathy, increased serum creatinine and cholelithiasis with fibrates. These recommendations will facilitate reduction in the substantial cardiovascular risk that persists in patients with cardiometabolic abnormalities at LDL-C goal. PMID:21531743

It also gives a firsthand look at fatal versus nonfatal CV events. Methods: The MarketScan® Commercial Claims and Encounters Database was used to identify adults with a CV event in 2006–2012 with hyperlipidemia or lipid-lowering therapy use in the 18 months prior to one of the following inpatient CV events: myocardial infarction, ischemic stroke, unstable angina, transient ischemic attack, percutaneous coronary intervention, or coronary artery bypass graft (CABG. Patients were required to have a preindex diagnosis of at least one of the following: peripheral arterial disease, abdominal aortic aneurysm, carotid artery disease, or diabetes. A subset analysis was conducted with patients with data linkable to the Social Security Administration Master Death File. Direct medical costs were reported for each quarter following a CV event, for up to 36 months after the first CV event. Results: In total, 38,609 CHD-RE patients were included, mean age 57 years, 31% female. CABG, myocardial infarction, and percutaneous coronary intervention were the most frequent and most expensive first CV events, accounting for >75% of all first CV events with mean first quarter costs ranging from $17,454 (nonfatal transient ischemic attack to $125,690 (fatal CABG. Overall, 15% of those with a first CV event went on to have a second event during the 36-month study period with mean first quarter nonfatal and fatal costs similar to first event levels. Third CV events were rare, happening in less than 3% of patients. Conclusion: CV events among CHD-RE patients were

    High triglyceride (TG) and low high-density lipoprotein cholesterol (HDL-C) are important cardiovascular risk factors. The exact prognostic value of the TG/HDL-C ratio, a marker for cardiovascular events, is currently unknown among Iranians so this study sought to determine the optimal cutoff point for the TG/HDL-C ratio in predicting cardiovascular disease events in the Iranian population. The Isfahan Cohort Study (ICS) is an ongoing, longitudinal, population-based study that was originally conducted on adults aged ≥ 35 years, living in urban and rural areas of three districts in central Iran. After 10 years of follow-up, 5431 participants were re-evaluated using a standard protocol similar to the one used for baseline. At both measurements, participants underwent medical interviews, physical examinations, and fasting blood measurements. "High-risk" subjects were defined by the discrimination power of indices, which were assessed using receiver operating characteristic (ROC) analysis; the optimal cutoff point value for each index was then derived. The mean age of the participants was 50.7 ± 11.6 years. The TG/HDL-C ratio, at a threshold of 3.68, was used to screen for cardiovascular events among the study population. Subjects were divided into two groups ("low" and "high" risk) according to the TG/HDL-C concentration ratio at baseline. A slightly higher number of high-risk individuals were identified using the European cutoff points of 63.7% in comparison with the ICS cutoff points of 49.5%. The unadjusted hazard ratio (HR) was greatest in high-risk individuals identified by the ICS cutoff points (HR = 1.54, 95% CI [1.33-1.79]) vs European cutoff points (HR = 1.38, 95% [1.17-1.63]). There were no remarkable changes after adjusting for differences in sex and age (HR = 1.58, 95% CI [1.36-1.84] vs HR = 1.44, 95% CI [1.22-1.71]) for the ICS and European cutoff points, respectively. The threshold of TG/HDL ≥ 3.68 is the optimal cutoff point for predicting

    In 2011, the United Nations (UN) organized the first ever meeting for heads of state to discuss the problem of noncommunicable diseases (NCD), including cardiovascular disease (CVD), cancer, chronic respiratory disease, and diabetes mellitus. Recognizing that these had emerged as leading causes of morbidity and mortality in the world, including in many low- and middle-income countries, advocates from government and civil society had called for increased attention and a UN response. Earlier, NCD including CVD were absent from the global health agenda in part because of their omission from the Millennium Development Goals. The UN meeting and the global advocacy response offered a game-changing opportunity to redress this omission. The World Heart Federation (WHF) played an instrumental role in the UN meeting and follow up, including inclusion of CVD in the Sustainable Development Goals. The next phase of the global CVD movement is expected through national action, including CVD roadmaps and partnering with the World Health Organization. The WHF is heavily committed to these goals and the other nongovernmental organizations invested in the mission must help take this historical mandate forward. Instrumental to this will be the engagement of people affected by or at risk of developing CVD, to draw more attention and resources to NCD and to ensure that successes to date in global policy translate into action at the national level.

    Adipose-derived stem cells (AdSCs) have recently been shown to differentiate into cardiovascular lineage cells. However, little is known about the fat tissue origin-dependent differences in AdSC function and differentiation potential. AdSC-rich cells were isolated from subcutaneous, visceral, cardiac (CA), and subscapular adipose tissue from mice and their characteristics analyzed. After four different AdSC types were cultured with specific differentiation medium, immunocytochemical analysis was performed for the assessment of differentiation into cardiovascular cells. We then examined the in vitro differentiation capacity and therapeutic potential of AdSCs in ischemic myocardium using a mouse myocardial infarction model. The cell density and proliferation activity of CA-derived AdSCs were significantly increased compared with the other adipose tissue-derived AdSCs. Immunocytochemistry showed that CA-derived AdSCs had the highest appearance rates of markers for endothelial cells, vascular smooth muscle cells, and cardiomyocytes among the AdSCs. Systemic transfusion of CA-derived AdSCs exhibited the highest cardiac functional recovery after myocardial infarction and the high frequency of the recruitment to ischemic myocardium. Moreover, long-term follow-up of the recruited CA-derived AdSCs frequently expressed cardiovascular cell markers compared with the other adipose tissue-derived AdSCs. Cardiac adipose tissue could be an ideal source for isolation of therapeutically effective AdSCs for cardiac regeneration in ischemic heart diseases. Significance: The present study found that cardiac adipose-derived stem cells have a high potential to differentiate into cardiovascular lineage cells (i.e., cardiomyocytes, endothelial cells, and vascular smooth muscle cells) compared with stem cells derived from other adipose tissue such as subcutaneous, visceral, and subscapular adipose tissue. Notably, only a small number of supracardiac adipose-derived stem cells that were

    OBJECTIVE: The purpose of this retrospective cohort study was to review pregnancy outcomes in morbidly obese women who delivered a baby weighing 500 g or more in a large tertiary referral university hospital in Europe. METHODS: Morbid obesity was defined as a BMI > or =40.0 kg\\/m2 (WHO). Only women whose BMI was calculated at their first antenatal visit were included. The obstetric out-comes were obtained from the hospital\\'s computerised database. RESULTS: The incidence of morbid obesity was 0.6% in 5,824 women. Morbidly obese women were older and were more likely to be multigravidas than women with a normal BMI. The pregnancy was complicated by hypertension in 35.8% and diabetes mellitus in 20.0% of women. Obstetric interventions were high, with an induction rate of 42.1% and a caesarean section rate of 45.3%. CONCLUSIONS: Our findings show that maternal morbid obesity is associated with an alarmingly high incidence of medical complications and an increased level of obstetric interventions. Consideration should be given to developing specialised antenatal services for morbidly obese women. The results also highlight the need to evaluate the effectiveness of prepregnancy interventions in morbidly obese women.

    Full Text Available Although moderate-intensity continuous training (MICT has been the traditional model for aerobic exercise training for over four decades, a growing body of literature has demonstrated equal if not greater improvement in aerobic capacity and similar beneficial effects on body composition, glucose metabolism, blood pressure, and quality of life from high-intensity interval training (HIIT. An advantage of HIIT over MICT is the shorter time required to perform the same amount of energy expenditure. The current brief review summarizes the effects of HIIT on peak aerobic capacity and cardiovascular risk factors in healthy adults and those with various cardiovascular diseases, including coronary artery disease, chronic heart failure, and post heart transplantation.

    Among the new cardiovascular event (CVE) risk biomarkers, C-reactive protein detected using high sensitive techniques (hs-CRP) has been one of the most commonly evaluated. In this review, the available evidence on the usefulness of hs-CRP was explored as an independent risk event factor in subjects with no cardiovascular history and as prognosis in case of chronic or acute cardiovascular condition. An overview (revision of revisions) was carried out searching in the main bibliographic databases and in other general Internet search engines. During the first stage, systematic reviews, clinical practice guidelines, health technology assessments and coverage policies were found and, during the second stage primary studies published after the systematic review search dates were added. Seven hundred and seventy four quotes were found, including 36 papers assessing the role of hs-CRP in healthy populations or with cardiovascular history. High quality evidence was found pointing out hs-CRP, both as risk factor in the general population and as prognostic factor in those with CVE, in all the populations assessed. It was most useful in subjects with a history of CVE and intermediate risk of events at 10 years; where adding hs-CRP to the classical models for event risk estimation improves risk staging. There was no consensus on its clinical usefulness as a prognostic marker in subjects with chronic or acute disease. Copyright © 2014 Instituto Nacional de Cardiología Ignacio Chávez.

    Patients with type2 diabetes mellitus have a high to very high cardiovascular risk, and often have other associated risk factors, such as hypertension, obesity and dyslipidaemia. Cardiovascular disease is the leading cause of morbidity and mortality in this population. An integrated control of all risk factors in patients with diabetes is essential for minimising the risk of macrovascular complications. Given the benefits of the multifactorial intervention strategies for cardiovascular prevention in diabetic patients, a review is presented on the therapeutic goals established for each risk factor in diabetes and the benefits of their control.

    Background.  There are limited data on clinical outcomes of hepatitis C virus (HCV) infection from low- and middle-income countries. We characterize mortality and liver disease progression in a cohort of people who inject drugs (PWID) with high HCV burden. Methods.  In a cohort of PWID in Chennai, India, 851 persons were observed semiannually. Information on death was obtained through verbal autopsy and liver disease progression, which was defined as an incident liver stiffness measurement of ≥12.3 kPa if it was <12.3 at baseline. Poisson and Cox regression were used to identify factors associated with mortality and disease progression, respectively. Results.  At baseline, 36.9% of cases were infected with HCV, 16.7% were infected with human immunodeficiency virus (HIV), 71.6% had no or mild stiffness, 14.9% had moderate stiffness, and 13.5% had severe stiffness or cirrhosis. Mortality was significantly higher among those with moderate (mortality rate ratio [MRR] = 2.31) and severe stiffness (MRR = 4.86) at baseline, those with ongoing substance use, those who were HIV monoinfected and not on antiretroviral therapy (ART) (MRR = 6.59), and those who were HIV/HCV coinfected regardless of ART status (MRR for no ART = 5.34; MRR for ART = 4.51). Of those with no or mild stiffness, 25.9% and 6.4% had evidence of progression to moderate and severe stiffness or cirrhosis, respectively; 38.3% of those with moderate stiffness had evidence of progression to severe stiffness or cirrhosis. Factors associated with progression included age, alcohol use, body mass index, and chronic HCV infection. Conclusions.  We observed significant morbidity and mortality primarily driven by untreated HIV, HIV/HCV coinfection, and alcohol use. Even with improved access to HIV treatment, in the absence of HCV treatment, outcomes are unlikely to improve for HIV/HCV-coinfected persons.

  12. Going beyond the disability-based morbidity definition in the compression of morbidity framework

    Directory of Open Access Journals (Sweden)

    Hiram Beltrán-Sánchez

    2014-09-01

    Full Text Available Background: As originally proposed by Fries, conceptualizing morbidity solely through associated functional limitation/disability (FL/D remains the most widely accepted metric to assess whether increases in longevity have been accompanied by a compression of morbidity. Objective: To propose a departure from a highly restrictive FL/D-based definition of “morbidity” to a broader view that considers the burden of chronic diseases even when no overt FL/D occur. Design: We outline three reasons why the current framework of compression of morbidity should be broadened to also consider morbidity to be present even when there are no overtly measurable FL/D. We discuss various scenarios of morbidity compression and morbidity expansion under this broader rubric of morbidity. Conclusion: The rationale to go beyond a purely FL/D-based definition of morbidity includes: (1 substantial damage from chronic disease that can develop prior to overt FL/D symptoms occurring; (2 multiple costs to the individual and society that extend beyond FL/D, including medication costs, health care visits, and opportunity costs of lifelong treatment; and (3 psychosocial and stress burden of being labeled as diseased and the consequence for overall well-being. Adopting this broader definition of morbidity suggests that increases in longevity have been possibly accompanied by an expansion of morbidity, in contrast to Fries' original hypothesis that morbidity onset (based on only FL/D would be delayed to a greater extent than increases in survival. There is an urgent need for better data and more research to document morbidity onset and its link with increases in longevity and assess the important question on whether populations while living longer are also healthier.

    To examine associations between measures of work stress (that is, the combination of high effort and low reward) and cardiovascular risk factors. Cross sectional first screening of a prospective cohort study. The study was conducted among 5720 healthy employed men and women living in the greater Stockholm area aged 19-70 years. All analyses were restricted to subjects with complete data (n = 4958). The investigation of associations between indicators of effort-reward imbalance and cardiovascular risk factors was restricted to the age group 30-55 years (n = 3427). Subjects reporting high effort and low reward at work had a higher prevalence of well known risk factors for coronary heart disease. After adjustment for relevant confounders, associations between a measure of extrinsic effort and reward (the effort-reward ratio) and hypertension (multivariate prevalence odds ratio (POR) 1.62-1.68), increased total cholesterol (upper tertile 220 mg/dl)(POR = 1.24) and the total cholesterol/high density lipoprotein(HDL)-cholesterol ratio (upper tertile 4.61)(POR 1.26-1.30) were found among men. Among women a measure of high intrinsic effort (immersion) was related to increased low density lipoprotein (LDL)-cholesterol (upper tertile 130 mg/dl)(POR 1.37-1.39). Analyses of variance showed increasing mean values of LDL cholesterol with an increasing degree of the effort-reward ratio among men and increased LDL-cholesterol among women with high levels of intrinsic effort (upper tertile of immersion). Findings lend support to the hypothesis that effort-reward imbalance represents a specific constellation of stressful experience at work related to cardiovascular risk. The relation was not explained by relevant confounders (for example, lack of physical exercise, body weight, cigarette smoking).

    Full Text Available Background. Xenon-in-oxygen is a high density gas mixture and may improve PaO2/FiO2 ratio in morbidly obese patients uniforming distribution of ventilation during anesthesia. Methods. We compared xenon versus sevoflurane anesthesia in twenty adult morbidly obese patients (BMI>35 candidate for roux-en-Y laparoscopic gastric bypass and assessed PaO2/FiO2 ratio at baseline, at 15 min from induction of anaesthesia and every 60 min during surgery. Differences in intraoperative and postoperative data including heart rate, systolic and diastolic pressure, oxygen saturation, plateau pressure, eyes opening and extubation time, Aldrete score on arrival to the PACU were compared by the Mann-Whitney test and were considered as secondary aims. Moreover the occurrence of side effects and postoperative analgesic demand were assessed. Results. In xenon group PaO2-FiO2 ratio was significantly higher after 60 min and 120 min from induction of anesthesia; heart rate and overall remifentanil consumption were lower; the eyes opening time and the extubation time were shorter; morphine consumption at 72 hours was lower; postoperative nausea was more common. Conclusions. Xenon anesthesia improved PaO2/FiO2 ratio and maintained its distinctive rapid recovery times and cardiovascular stability. A reduction of opioid consumption during and after surgery and an increased incidence of PONV were also observed in xenon group.

    Introduction Technology-mediated strategies have potential to engage patients in modifying unhealthy behaviour and improving medication adherence to reduce morbidity and mortality from cardiovascular disease (CVD). Furthermore, electronic tools offer a medium by which consumers can more actively navigate personal healthcare information. Understanding how, why and among whom such strategies have an effect can help determine the requirements for implementing them at a scale. This paper aims to detail a process evaluation that will (1) assess implementation fidelity of a multicomponent eHealth intervention; (2) determine its effective features; (3) explore contextual factors influencing and maintaining user engagement; and (4) describe barriers, facilitators, preferences and acceptability of such interventions. Methods and analysis Mixed-methods sequential design to derive, examine, triangulate and report data from multiple sources. Quantitative data from 3 sources will help to inform both sampling and content framework for the qualitative data collection: (1) surveys of patients and general practitioners (GPs); (2) software analytics; (3) programme delivery records. Qualitative data from interviews with patients and GPs, focus groups with patients and field notes taken by intervention delivery staff will be thematically analysed. Concurrent interview data collection and analysis will enable a thematic framework to evolve inductively and inform theory building, consistent with a realistic evaluation perspective. Eligible patients are those at moderate-to-high CVD risk who were randomised to the intervention arm of a randomised controlled trial of an eHealth intervention and are contactable at completion of the follow-up period; eligible GPs are the primary healthcare providers of these patients.

    In the present study, we tested the hypothesis that the PPARgamma (peroxisome-proliferator-activated receptor gamma) activator rosiglitazone improves vascular structure and function in aged hyperhomocysteinaemic MTHFR (methylene tetrahydrofolate reductase) gene heterozygous knockout (mthfr+/-) mice fed a HCD (high-cholesterol diet), a model of high cardiovascular risk. One-year-old mthfr+/- mice were fed or not HCD (6 mg x kg-1 of body weight x day-1) and treated or not with rosiglitazone (20 mg x kg-1 of body weight x day-1) for 90 days and compared with wild-type mice. Endothelium-dependent relaxation of carotid arteries was significantly impaired (-40%) only in rosiglitazone-treated HCD-fed mthfr+/- mice. Carotid M/L (media-to-lumen ratio) and CSA (cross-sectional area) were increased (2-fold) in mthfr+/- mice fed or not HCD compared with wild-type mice (P<0.05). Rosiglitazone reduced M/L and CSA only in mthfr+/- mice fed a normal diet. Superoxide production was increased in mthfr+/- mice fed HCD treated or not with rosiglitazone, whereas plasma nitrite was decreased by rosiglitazone in mice fed or not HCD. PRMT-1 (protein arginine methyltransferase-1), involved in synthesis of the NO (nitric oxide) synthase inhibitor ADMA (asymmetric omega-NG,NG-dimethylarginine), and ADMA were increased only in rosiglitazone-treated HCD-fed mthfr+/- mice. Rosiglitazone had both beneficial and deleterious vascular effects in this animal model of high cardiovascular risk: it prevented carotid remodelling, but impaired endothelial function in part through enhanced oxidative stress and increased ADMA production in mice at high cardiovascular risk.

    2016-01-01

    Cardiovascular complications remain the leading causes of morbidity and premature mortality in patients with diabetes. Studies in humans and preclinical models demonstrate lasting gene expression changes in the vasculopathies initiated by previous exposure to high glucose concentrations and the associated overproduction of reactive oxygen species. The molecular signatures of chromatin architectures that sensitize the genome to these and other cardiometabolic risk factors of the diabetic milieu are increasingly implicated in the biologic memory underlying cardiovascular complications and now widely considered as promising therapeutic targets. Atherosclerosis is a complex heterocellular disease where the contributing cell types possess distinct epigenomes shaping diverse gene expression. While the extent that pathological chromatin changes can be manipulated in human cardiovascular disease remains to be established, the clinical applicability of epigenetic interventions will be greatly advanced by a deeper understanding of the cell type-specific roles played by writers, erasers, and readers of chromatin modifications in the diabetic vasculature. This review details a current perspective of epigenetic mechanisms of macrovascular disease in diabetes, and highlights recent key descriptions of chromatinized changes associated with persistent gene expression in endothelial, smooth muscle, and circulating immune cells relevant to atherosclerosis. Furthermore we discuss the challenges associated with pharmacological targeting of epigenetic networks to correct abnormal or deregulated gene expression as a strategy to alleviate the clinical burden of diabetic cardiovascular disease.

    Visit-to-visit variability in blood pressure is an independent predictor of cardiovascular disease. This study investigates biological correlates of intra-individual variability in blood pressure in older persons. Nested observational study within the PROspective Study of Pravastatin in the Elderly at Risk (PROSPER) among 3,794 male and female participants (range 70-82 years) with a history of, or risk factors for cardiovascular disease. Individual visit-to-visit variability in systolic and diastolic blood pressure and pulse pressure (expressed as 1 SD in mm Hg) was assessed using nine measurements over 2 years. Correlates of higher visit-to-visit variability were examined at baseline, including markers of inflammation, endothelial function, renal function and glucose homeostasis. Over the first 2 years, the mean intra-individual variability (1 SD) was 14.4mm Hg for systolic blood pressure, 7.7mm Hg for diastolic blood pressure, and 12.6mm Hg for pulse pressure. After multivariate adjustment a higher level of interleukin-6 at baseline was consistently associated with higher intra-individual variability of blood pressure, including systolic, diastolic, and pulse pressure. Markers of endothelial function (Von Willebrand factor, tissue plasminogen activator), renal function (glomerular filtration rate) and glucose homeostasis (blood glucose, homeostatic model assessment index) were not or to a minor extent associated with blood pressure variability. In an elderly population at risk of cardiovascular disease, inflammation (as evidenced by higher levels of interleukin-6) is associated with higher intra-individual variability in systolic, diastolic, and pulse pressure. © American Journal of Hypertension, Ltd 2014.

  10. Candidates for Bariatric Surgery: Morbidly Obese Patients with Pulmonary Dysfunction

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Obesity is a well-known major risk factor of cardiovascular disease and is associated with various comorbidities. The impact of obesity on pulmonary function remains unclear. Reductions in chest wall compliance and respiratory muscle strength due to a high percent body fat and localized fat distribution contributes to impaired pulmonary function and the occurrence of adverse respiratory symptoms. Dietary modifications and pharmaceutical agents are not effective in the long-term treatment of obesity. Treatment of morbidly obese patients using bariatric surgery has increased each year, especially after the introduction of video laparoscopic techniques. Effective weight loss after bariatric surgery may improve cardiovascular disease risk factors, including diabetes, hypertension, dyslipidemia, atherosclerosis, inflammation, chronic kidney disease, obstructive sleep apnea, and obesity hypoventilation syndrome. Bariatric surgery has also been associated with significantly improved respiratory symptoms and pulmonary function. We currently present a review of principal studies that evaluated the effects of obesity on pulmonary function and the identification of anthropometric factors of obesity that correspond to the reversal of respiratory symptoms and impaired pulmonary function after bariatric surgery.

    2010-06-01

    Full Text Available Abstract Background Multiple randomized controlled trials (RCTs have examined the cardiovascular effects of omega-3 fatty acids and have provided unexplained conflicting results. A meta-analysis of these RCTs to estimate efficacy and safety and potential sources of heterogeneity may be helpful. Methods The Cochrane library, MEDLINE, and EMBASE were systematically searched to identify all interventional trials of omega-3 fatty acids compared to placebo or usual diet in high-risk cardiovascular patients. The primary outcome was all-cause mortality and secondary outcomes were coronary restenosis following percutaneous coronary intervention and safety. Meta-analyses were carried out using Bayesian random-effects models, and heterogeneity was examined using meta-regression. Results A total of 29 RCTs (n = 35,144 met our inclusion criteria, with 25 reporting mortality and 14 reporting restenosis. Omega-3 fatty acids were not associated with a statistically significant decreased mortality (relative risk [RR] = 0.88, 95% Credible Interval [CrI] = 0.64, 1.03 or with restenosis prevention (RR = 0.89, 95% CrI = 0.72, 1.06, though the probability of some benefit remains high (0.93 and 0.90, respectively. However in meta-regressions, there was a >90% probability that larger studies and those with longer follow-up were associated with smaller benefits. No serious safety issues were identified. Conclusions Although not reaching conventional statistical significance, the evidence to date suggests that omega-3 fatty acids may result in a modest reduction in mortality and restenosis. However, caution must be exercised in interpreting these benefits as results were attenuated in higher quality studies, suggesting that bias may be at least partially responsible. Additional high quality studies are required to clarify the role of omega-3 fatty acid supplementation for the secondary prevention of cardiovascular disease.

    2014-01-01

    Full Text Available The current search for new markers of cardiovascular diseases (CVDs is explained by the high morbidity and mortality still observed in developed and developing countries due to cardiovascular events. Recently, microRNAs (miRNAs or miRs have emerged as potential new biomarkers and are small sequences of RNAs that regulate gene expression at posttranscriptional level by inhibiting translation or inducing degradation of the target mRNAs. Circulating miRNAs are involved in the regulation of signaling pathways associated to aging and can be used as novel diagnostic markers for acute and chronic diseases such as cardiovascular pathologies. This review summarizes the biogenesis, maturation, and stability of miRNAs and their use as potential biomarkers for coronary artery disease (CAD, myocardial infarction (MI, and heart failure (HF.

    2002-03-01

    The tracheas of obese patients may be more difficult to intubate than those of normal-weight patients. We studied 100 morbidly obese patients (body mass index >40 kg/m(2)) to identify which factors complicate direct laryngoscopy and tracheal intubation. Preoperative measurements (height, weight, neck circumference, width of mouth opening, sternomental distance, and thyromental distance) and Mallampati score were recorded. The view during direct laryngoscopy was graded, and the number of attempts at tracheal intubation was recorded. Neither absolute obesity nor body mass index was associated with intubation difficulties. Large neck circumference and high Mallampati score were the only predictors of potential intubation problems. Because in all but one patient the trachea was intubated successfully by direct laryngoscopy, the neck circumference that requires an intervention such as fiberoptic bronchoscopy to establish an airway remains unknown. We conclude that obesity alone is not predictive of tracheal intubation difficulties. In 100 morbidly obese patients, neither obesity nor body mass index predicted problems with tracheal intubation. However, a high Mallampati score (greater-than-or-equal to 3) and large neck circumference may increase the potential for difficult laryngoscopy and intubation.

  18. Finite element modeling of mass transport in high-Péclet cardiovascular flows

    Hansen, Kirk; Arzani, Amirhossein; Shadden, Shawn

    2016-11-01

    Mass transport plays an important role in many important cardiovascular processes, including thrombus formation and atherosclerosis. These mass transport problems are characterized by Péclet numbers of up to 108, leading to several numerical difficulties. The presence of thin near-wall concentration boundary layers requires very fine mesh resolution in these regions, while large concentration gradients within the flow cause numerical stabilization issues. In this work, we will discuss some guidelines for solving mass transport problems in cardiovascular flows using a stabilized Galerkin finite element method. First, we perform mesh convergence studies in a series of idealized and patient-specific geometries to determine the required near-wall mesh resolution for these types of problems, using both first- and second-order tetrahedral finite elements. Second, we investigate the use of several boundary condition types at outflow boundaries where backflow during some parts of the cardiac cycle can lead to convergence issues. Finally, we evaluate the effect of reducing Péclet number by increasing mass diffusivity as has been proposed by some researchers. This work was supported by the NSF GRFP and NSF Career Award #1354541.

    Metabolomics approach is focused on identifying all metabolites present in a biological sample (metabolome). Consumption of cocoa products has been related to health benefits including positive effect on cardiovascular health. Twenty volunteers were included in this randomized, crossover, and controlled clinical trial. After a 2-wk washout period, subjects received 40 g/day of cocoa powder with 500 mL skimmed milk (cocoa with skimmed milk intervention) or 500 mL/day of skimmed milk (skimmed milk intervention) for 4-wk. Urine (24 h) samples were collected at baseline and after each intervention and were analyzed by HPLC-hybrid quadrupole TOF in negative and positive ionization modes followed by multivariate analysis. This analysis revealed a marked separation between the cocoa with skimmed milk intervention and skimmed milk intervention and baseline periods. Thirty-nine compounds linked with cocoa intake, including alkaloid metabolites, polyphenol host and gut microbial metabolites (hydroxyphenylvalerolactones and hydroxyphenylvaleric acids), diketopiperazines and N-phenylpropenoyl-l-amino acids were identified. In the case of endogenous metabolites, putative identifications suggested that metabolites linked with carnitine metabolism and sulfation of tyrosine were decreased by the consumption of cocoa. LC-MS metabolomics strategy allows the defining of a complex metabolic profile derived from cocoa phytochemicals. Likewise, the identification of endogenous markers could lead to new hypotheses to unravel the relationship between cocoa intake and cardiovascular diseases. © 2013 WILEY-VCH Verlag GmbH & Co.

  20. Dyslipidemia, kidney disease, and cardiovascular disease in diabetic patients.

    Science.gov (United States)

    Chen, Szu-chi; Tseng, Chin-Hsiao

    2013-01-01

    This article reviews the relationship between dyslipidemia, chronic kidney disease, and cardiovascular diseases in patients with diabetes. Diabetes mellitus is associated with complications in the cardiovascular and renal system, and is increasing in prevalence worldwide. Modification of the multifactorial risk factors, in particular dyslipidemia, has been suggested to reduce the rates of diabetes-related complications. Dyslipidemia in diabetes is a condition that includes hypertriglyceridemia, low high-density lipoprotein levels, and increased small and dense low-density lipoprotein particles. This condition is associated with higher cardiovascular risk and mortality in diabetic patients. Current treatment guidelines focus on lowering the low-density lipoprotein cholesterol level; multiple trials have confirmed the cardiovascular benefits of treatment with statins. Chronic kidney disease also contributes to dyslipidemia, and dyslipidemia in turn is related to the occurrence and progression of diabetic nephropathy. Different patterns of dyslipidemia are associated with different stages of diabetic nephropathy. Some trials have shown that treatment with statins not only decreased the risk of cardiovascular events, but also delayed the progression of diabetic nephropathy. However, studies using statins as the sole treatment of hyperlipidemia in patients on dialysis have not shown benefits with respect to cardiovascular risk. Diabetic patients with nephropathy have a higher risk of cardiovascular events than those without nephropathy. The degree of albuminuria and the reduction in estimated glomerular filtration rate are also correlated with the risk of cardiovascular events. Treatment with angiotensin-converting enzyme inhibitors and angiotensin II receptor blockers to reduce albuminuria in diabetic patients has been shown to decrease the risk of cardiovascular morbidity and mortality.

  3. Radiation-induced cardiovascular effects

    Science.gov (United States)

    Tapio, Soile

    Recent epidemiological studies indicate that exposure to ionising radiation enhances the risk of cardiovascular mortality and morbidity in a moderate but significant manner. Our goal is to identify molecular mechanisms involved in the pathogenesis of radiation-induced cardiovascular disease using cellular and mouse models. Two radiation targets are studied in detail: the vascular endothelium that plays a pivotal role in the regulation of cardiac function, and the myocardium, in particular damage to the cardiac mitochondria. Ionising radiation causes immediate and persistent alterations in several biological pathways in the endothelium in a dose- and dose-rate dependent manner. High acute and cumulative doses result in rapid, non-transient remodelling of the endothelial cytoskeleton, as well as increased lipid peroxidation and protein oxidation of the heart tissue, independent of whether exposure is local or total body. Proteomic and functional changes are observed in lipid metabolism, glycolysis, mitochondrial function (respiration, ROS production etc.), oxidative stress, cellular adhesion, and cellular structure. The transcriptional regulators Akt and PPAR alpha seem to play a central role in the radiation-response of the endothelium and myocardium, respectively. We have recently started co-operation with GSI in Darmstadt to study the effect of heavy ions on the endothelium. Our research will facilitate the identification of biomarkers associated with adverse cardiac effects of ionising radiation and may lead to the development of countermeasures against radiation-induced cardiac damage.

Design Best case scenario analysis using a Markov model. Setting Australian Diabetes, Obesity and Lifestyle study. Participants 2013 people with hypertension who met the criteria for metabolic syndrome, with no history of cardiovascular disease and not receiving antihypertensive therapy. Main outcome measures Treatment effects associated with dark chocolate consumption derived from published meta-analyses were used to determine the absolute number of cardiovascular events with and without treatment. Costs associated with cardiovascular events and treatments were applied to determine the potential amount of funding required for dark chocolate therapy to be considered cost effective. Results Daily consumption of dark chocolate (polyphenol content equivalent to 100 g of dark chocolate) can reduce cardiovascular events by 85 (95% confidence interval 60 to 105) per 10 000 population treated over 10 years. $A40 (£25; €31; $42) could be cost effectively spent per person per year on prevention strategies using dark chocolate. These results assume 100% compliance and represent a best case scenario. Conclusions The blood pressure and cholesterol lowering effects of dark chocolate consumption are beneficial in the prevention of cardiovascular events in a population with metabolic syndrome. Daily dark chocolate consumption could be an effective cardiovascular preventive strategy in this population. PMID:22653982

    A retrospective further analysis of the ACTION database evaluated the relationship between cardiovascular outcomes and the "quality" of the control of blood pressure (BP). The study population (n = 6287) comprised those patients with four BP measurements during year 1 subdivided according to the proportion of visits in which BP was controlled in relation to two BP targets: risk of stroke but were still apparent for all the other endpoints. For example, the risks for the primary outcome [hazard ratio (HR) 0.78; 95% confidence interval (CI) 0.67 to 0.90] were significantly less in the group with >_75% of visits with BP control than in the group with < 25% of visits with BP control. There were no significant treatment-related differences. Retrospective analyses are not definitive but these results highlight the importance of the attainment of BP control targets and the consistency of BP control during long-term follow-up.

    Full Text Available Studies on cardiovascular safety in cancer patients treated with highly or moderately emetogenic chemotherapy (HEC or MEC, who may have taken the antiemetic, aprepitant, have been limited to clinical trials and postmarketing spontaneous reports. Our study explored background rates of cardiovascular disease (CVD events among HEC- or MEC-treated cancer patients in a population-based setting to contextualize events seen in a new drug development program and to determine at a high level whether rates differed by aprepitant usage. Medical and pharmacy claims data from the 2005–2007 IMPACT National Benchmark Database were classified into emetogenic chemotherapy categories and CVD outcomes. Among 5827 HEC/MEC-treated patients, frequencies were highest for hypertension (16–21% and composites of venous (7–12% and arterial thromboembolic events (4–7%. Aprepitant users generally did not experience higher frequencies of events compared to nonusers. Our study serves as a useful benchmark of background CVD event rates in a population-based setting of cancer patients.

    Despite the evidence supporting metabolic benefits of high intensity interval exercise (HIIT), there is little information about the cardiovascular response to this type of exercise in patients with type 2 diabetes (T2D) and hypertension (HTA). To analyze the changes in heart rate at rest, at the onset and at the end of each interval of training, after twelve weeks of a HIIT program in T2D and HTA patients. Twenty-three participants with T2D and HTA (20 women) participated in a controlled HIIT program. Fourteen participants attended 90% of more session of exercise and were considered as adherent. Adherent and non-adherent participants had similar body mass index (BMI), and blood pressure. A “1x2x10” (work: rest-time: intervals) HIIT exercise protocol was used both as a test and as training method during twelve weeks. The initial and finishing heart rate (HR) of each of the ten intervals before and after the intervention were measured. After twelve weeks of HIIT intervention, adherent participants had a significant reduction in the heart rate at the onset of exercise, and during intervals 4, 5, 8 and 10. A reduction in the final heart rate was observed during intervals 8 and 10. In the same participants the greatest magnitude of reduction, at the onset or end of exercise was approximately 10 beats/min. No significant changes in BMI, resting heart rate and blood pressure were observed. A HIIT program reduces the cardiovascular effort to a given work-load and improves cardiovascular recovery after exercise.

    Full Text Available Consumption of sugar has been relatively high in the Nordic countries; the impact of sugar intake on metabolic risk factors and related diseases has been debated. The objectives were to assess the effect of sugar intake (sugar-sweetened beverages, sucrose and fructose on association with type 2 diabetes, cardiovascular disease and related metabolic risk factors (impaired glucose tolerance, insulin sensitivity, dyslipidemia, blood pressure, uric acid, inflammation markers, and on all-cause mortality, through a systematic review of prospective cohort studies and randomised controlled intervention studies published between January 2000 and search dates. The methods adopted were as follows: the first search was run in PubMed in October 2010. A second search with uric acid as risk marker was run in April 2011. The total search strategy was rerun in April 2011 in SveMed+. An update was run in PubMed in January 2012. Two authors independently selected studies for inclusion from the 2,743 abstracts according to predefined eligibility criteria. The outcome was that out of the 17 studies extracted, 15 were prospective cohort studies and two were randomised controlled crossover trials. All of the studies included only adults. With respect to incident type 2 diabetes (nine studies, four of six prospective cohort studies found a significant positive association for sugar-sweetened beverage intake. In general, larger cohort studies with longer follow-up more often reported positive associations, and BMI seemed to mediate part of the increased risk. For other metabolic or cardiovascular risk factors or outcomes, too few studies have been published to draw conclusions. In conclusion, data from prospective cohort studies published in the years 2000–2011 suggest that sugar-sweetened beverages probably increase the risk of type 2 diabetes. For related metabolic risk factors, cardiovascular disease or all-cause mortality and other types of sugars, too few studies

    Background The association between high-sensitivity C-reactive protein and recurrent major adverse cardiovascular events (MACE) in patients with ST-elevation myocardial infarction who undergo primary percutaneous coronary intervention remains controversial. Objective To investigate the potential association between high-sensitivity C-reactive protein and an increased risk of MACE such as death, heart failure, reinfarction, and new revascularization in patients with ST-elevation myocardial infarction treated with primary percutaneous coronary intervention. Methods This prospective cohort study included 300 individuals aged >18 years who were diagnosed with ST-elevation myocardial infarction and underwent primary percutaneous coronary intervention at a tertiary health center. An instrument evaluating clinical variables and the Thrombolysis in Myocardial Infarction (TIMI) and Global Registry of Acute Coronary Events (GRACE) risk scores was used. High-sensitivity C-reactive protein was determined by nephelometry. The patients were followed-up during hospitalization and up to 30 days after infarction for the occurrence of MACE. Student's t, Mann-Whitney, chi-square, and logistic regression tests were used for statistical analyses. P values of ≤0.05 were considered statistically significant. Results The mean age was 59.76 years, and 69.3% of patients were male. No statistically significant association was observed between high-sensitivity C-reactive protein and recurrent MACE (p = 0.11). However, high-sensitivity C-reactive protein was independently associated with 30-day mortality when adjusted for TIMI [odds ratio (OR), 1.27; 95% confidence interval (CI), 1.07-1.51; p = 0.005] and GRACE (OR, 1.26; 95% CI, 1.06-1.49; p = 0.007) risk scores. Conclusion Although high-sensitivity C-reactive protein was not predictive of combined major cardiovascular events within 30 days after ST-elevation myocardial infarction in patients who underwent primary angioplasty and stent

    Contemporary epidemiological data on blood pressure readings, hypertension prevalence and control in unselected patient populations covering a broad age range are scarce. The aim here is to report the prevalence of high blood pressure and to identify factors associated with blood pressure control in a large German primary care sample. We used data from the German Metabolic and Cardiovascular Risk Study including 35 869 patients aged 18-99 years. High blood pressure was defined as systolic blood pressure ≥140 mm Hg and/or diastolic blood pressure ≥90 mm Hg or using antihypertensive therapy. Factors associated with blood pressure control among patients receiving antihypertensive therapy were examined using multiple logistic regressions to estimate odds ratios and 95% confidence intervals. The prevalence of high blood pressure, uncontrolled high blood pressure and untreated high blood pressure was 54.8%, 21.3% and 17.6%, respectively. Age >50 years (1.52; 1.40-1.65), male sex (1.30; 1.20-1.41), elevated waist circumference (1.55; 1.45-1.65), high cholesterol (1.24; 1.16-1.33), high triglycerides (1.11; 1.04-1.19) and concomitant diabetes (1.29; 1.20-1.40) were independently associated with uncontrolled high blood pressure. In a majority of patients we observed hypertension despite treatment for high blood pressures. Studies examining the reasons for treatment failure are highly warranted.

    Arterial hypertension is an important cardiovascular risk factor. The benefit drawn from decreasing and normalizing the blood pressure level is indisputable. The ACCOMPLISH study performed in patients older than 65 with systolic hypertension and a high cardiovascular risk pointed out the interest of well choosing the antihypertensive combination to reduce this risk beyond the decrease of blood pressure. The association of benazepril (an angiotensin converting enzyme inhibitor or ACEI) and amlodipine (a calcium antagonist) has shown significant early cardiovascular protection in such patients as compared to the classic association including the same ACEI and hydrochlorothiazide, in spite of the same target blood pressure reached. This important finding does not contest the interest of a well controlled blood pressure in hypertension, but probably will modify our first antihypertensive combination choice in the future in patients with such cardiovascular profile.

    Full Text Available Background: One of Europe’s most well-developed industrial regions is found in the Republic of Bulgaria. The industrialization of the region has a big impact on air pollution. Thermal power plant “Maritza East” (the largest of its kind in southeastern Europe, the army training range, machine manufacturers, household heating and high volume of automobile traffic are all major sources of pollution in the region.Methods: A five year study (2009-2013 followed yearly concentrations of principal atmospheric pollutants such as sulfur dioxide, dust, nitrogen dioxide, lead aerosols and hydrogen sulfide, and the way in which those levels had an effect on morbidity (outpatient and inpatient medical care in the area. Statistical processing of data has been completed to represent and analyze the collected data in nonparametric and alternative format.Results: Atmospheric pollution affects human health directly through pathological changes in the human organism. The registered outpatient care provided for the period 2009-2013 is highest for diseases of the cardiovascular system (11.85%, the respiratory system (17.34% and the genitourinary system (9.76%. The registered rate of hospitalization for the same period is for diseases of the digestive system (11.90%, the cardiovascular system (11.85%, respiratory system (10.86% and the genitourinary system (8.88%.Conclusion: The observed period shows a decrease in average yearly concentrations of the principal atmospheric pollutants in the industrial region (Bulgaria and reflects a decrease in morbidity based on outpatient care and an increase in morbidity by inpatient care (hospitalization. Our findings should be corroborated in future longitudinal studies. Keywords: Atmospheric pollution, Morbidity, Industrial region, Bulgaria

    The atherogenic role of triglycerides (TG) remains controversial. The aim of the present study is to analyze the contribution of TG in the pathogenesis of erectile dysfunction (ED) and to verify the value of elevated TG in predicting major adverse cardiovascular events (MACE). An unselected series of 3,990 men attending our outpatient clinic for sexual dysfunction was retrospectively studied. A subset of this sample (n = 1,687) was enrolled in a longitudinal study. Several clinical, biochemical, and instrumental (penile color Doppler ultrasound; PCDU) factors were evaluated. Among the patients studied, after adjustment for confounders, higher TG levels were associated with arteriogenic ED and a higher risk of clinical and biochemical hypogonadism. Conversely, no association between TG and other sexual dysfunctions was observed. When pathological PCDU parameters-including flaccid acceleration (<1.17 m/sec(2)) or dynamic peak systolic velocity (PSV <35 cm/sec)-were considered, the negative association between impaired penile flow and higher TG levels was confirmed, even when subjects taking lipid-lowering drugs or those with diabetes were excluded from the analysis (OR = 6.343 [1.243;32.362], P = .026 and 3.576 [1.104;11.578]; P = .34 for impaired acceleration and PSV, respectively). Similarly, when the same adjusted models were applied, TG levels were associated with a higher risk of hypogonadism, independently of the definition criteria (OR = 2.892 [1.643;5.410], P < .0001 and 4.853 [1.965;11.990]; P = .001 for total T <12 and 8 nM, respectively). In the longitudinal study, after adjusting for confounders, elevated TG levels (upper quartile: 162-1686 mg/dL) were independently associated with a higher incidence of MACE (HR = 2.469 [1.019;5.981]; P = .045), when compared to the rest of the sample. Our data suggest an association between elevated TG and arteriogenic ED and its cardiovascular (CV) risk stratification. Whether the use of TG lowering drugs

    Introducción: la hipercolesterolemia es uno de los principales factores de riesgo modificables de la enfermedad cardiovascular (ECV). Su reducción disminuye la morbimortalidad por cardiopatía isquémica y ECV en general, en prevención primaria y, especialmente, en prevención secundaria. Objetivo: comprobar si una práctica clínica protocolizada e intensiva permite vencer la inercia y alcanzar el objetivo terapéutico (OT) de c-LDL infarto agudo de miocardio (20,33 %), angina (16,07 %), ictus/AIT (9,19 %), artropatía (5,25 %), diabetes (70,87 %), hipertensión (71,01 %) y obesidad abdominal (69,62 %). El 43,57 % (IC95 %: 37,21; 50,08) de los pacientes que realizaron la segunda visita (241) consiguieron el OT. El 62,50 % (IC95 %: 55,68; 68,98) de los que realizaron la tercera (216) consiguieron el OT. Finalmente, el 77,56 % (IC95 %: 72,13; 83,08) de los pacientes que realizaron la última visita (205) consiguieron el OT. A lo largo del estudio hubo una reducción de los niveles de c-LDL desde los 135,6 mg/dL en la visita basal, 107,4 mg/dL en la segunda visita, 97,3 mg/dL en la tercera visita, hasta los 90,7 mg/dL en la visita final (p < 0,0001). El incremento de c-HDL entre la visita basal (50,9 mg/dL) y la final (53,6 mg/dL) también fue significativo (p = 0,013). Conclusiones: la reevaluación e intensificación del tratamiento en pacientes de alto riesgo cardiovascular atendidos en Atención Primaria, aplicando las indicaciones de las guías, permite alcanzar el OT en más de las tres cuartas partes de los previamente no controlados en el plazo de medio año. Estos resultados nos deben estimular a superar la inercia terapéutica en el control de la ECV mediante una actuación precoz y enérgica ante la hipercolesterolemia.

    Vacuum-assisted closure(VAC) therapy is mainly used for tissue defects. VAC therapy can remove exudate that could impair the healing process. We applied VAC therapy in patients considered at high risk of surgical site infection who underwent cardiovascular surgery via standard median sternotomy. Risk factors included advanced heart failure, obesity, diabetes mellitus, steroid administration, immunosuppressant administration, and chronic renal failure, etc. VAC therapy was used in 134 patients. Only 3 of these patients (2.2%) developed surgical site infection caused by Staphylococcus epidermidis;2 patients fully recovered after prolonged VAC therapy for 2 weeks, and the other required an additional sternal fixation after the sternal wires were removed for wound infection control. No patient developed infective mediastinitis. Prophylactic VAC therapy can reduce postoperative wound infection in high risk patients undergoing open heart surgery via full sternotomy.

    Epidemiological studies showed that PR prolongation is associated with increased risk of adverse cardiovascular outcomes. We investigated the relations of PR interval with indices of vascular function and endothelial repair as the underlying mechanisms. The study comprised 348 high-risk patients with prior coronary artery disease, ischemic stroke, and/or diabetes mellitus recruited from medical outpatient clinics and 150 healthy subjects without such a history. PR interval was considered prolonged if >200 ms, as determined from resting 12-lead electrocardiogram. Vascular function was assessed by brachial flow-meditated dilatation (FMD) using high-resolution ultrasound. Circulating CD133(+)/KDR(+) endothelial progenitor cell (EPC) levels were measured by flow cytometry. Among healthy subjects, PR interval was inversely associated with FMD (R = -0.20, P = 0.015), but not with the level of circulating CD133(+)/KDR(+) EPC (R = 0.05, P = 0.58). Among high-risk cardiovascular patients, PR prolongation >200 ms was more common compared with healthy subjects (45/348 (13 %) versus 4/150 (3 %), P PR interval was associated inversely with FMD (R = -0.14, P = 0.01) and positively with circulating CD133(+)/KDR(+) EPC level (R = +0.14, P = 0.009). Circulating CD133(+)/KDR(+) EPC level was significantly increased in patients with PR prolongation >200 ms (0.87 ± 0.37 versus 0.68 ± 0.42 (log, ×10(-3)/ml), P = 0.005). Adjusted for potential confounders, increased PR interval remained independently associated with increased CD133(+)/KDR(+) EPC by +0.002 (95 % confidence interval (CI) 0.000 to 0.004 (log, ×10(-3)/ml), P = 0.011) and depressed FMD (B = -0.014 %, 95 % CI -0.027 to -0.002, P = 0.026). PR prolongation is associated with endothelial dysfunction and evidence of endothelial repair activation in patients with high cardiovascular risk.

    Determination of the postoperative morbidity and mortality after gastroenterostomy in patients with unresectable gastric cancer. Retrospective review of clinical records of all patients with obstructive distal gastric cancer who underwent gastroenterostomy at the Instituto de Enfermedades Neoplásicas between 1980 and 1993. The following factors were analyzed: age, sex, hemoglobin, albumin, preoperative risk, ascites, extent of disease, operative time, hospital stay, morbidity and mortality. 198 gastroenterostomy were done with a morbidity and mortality rates of 20% and 10%, respectively. Pneumonia was the principal cause of postoperative morbidity and mortality. High operative risk, adjacent organ invasion by the tumor and peritoneal metastasis were factors associated with increased postoperative morbidity (p > 0.05). High operative risk was the only prognostic factor for postoperative mortality (p < 0.01). Because of high postoperative morbidity and mortality, gastroenterostomy should not be done in patients with unresectable gastric cancer and high preoperative risk.

    Full Text Available INTRODUCTION: To develop and test a diabetes risk score to predict incident diabetes in an elderly Spanish Mediterranean population at high cardiovascular risk. MATERIALS AND METHODS: A diabetes risk score was derived from a subset of 1381 nondiabetic individuals from three centres of the PREDIMED study (derivation sample. Multivariate Cox regression model ß-coefficients were used to weigh each risk factor. PREDIMED-personal Score included body-mass-index, smoking status, family history of type 2 diabetes, alcohol consumption and hypertension as categorical variables; PREDIMED-clinical Score included also high blood glucose. We tested the predictive capability of these scores in the DE-PLAN-CAT cohort (validation sample. The discrimination of Finnish Diabetes Risk Score (FINDRISC, German Diabetes Risk Score (GDRS and our scores was assessed with the area under curve (AUC. RESULTS: The PREDIMED-clinical Score varied from 0 to 14 points. In the subset of the PREDIMED study, 155 individuals developed diabetes during the 4.75-years follow-up. The PREDIMED-clinical score at a cutoff of ≥6 had sensitivity of 72.2%, and specificity of 72.5%, whereas AUC was 0.78. The AUC of the PREDIMED-clinical Score was 0.66 in the validation sample (sensitivity = 85.4%; specificity = 26.6%, and was significantly higher than the FINDRISC and the GDRS in both the derivation and validation samples. DISCUSSION: We identified classical risk factors for diabetes and developed the PREDIMED-clinical Score to determine those individuals at high risk of developing diabetes in elderly individuals at high cardiovascular risk. The predictive capability of the PREDIMED-clinical Score was significantly higher than the FINDRISC and GDRS, and also used fewer items in the questionnaire.

The predictive capability of the PREDIMED-clinical Score was significantly higher than the FINDRISC and GDRS, and also used fewer items in the questionnaire. PMID:22442692

    Full Text Available ABSTRACT: The prevalence of obesity continues to increase and represents one of the principal causes of cardiovascular morbidity and mortality. After the discovery of a specific receptor of the psychoactive principle of marijuana, the cannabinoid receptors and their endogenous ligands, several studies have demonstrated the role of this system in the control of food intake and energy balance and its overactivity in obesity. Recent studies with the CB1 receptor antagonist rimonabant have demonstrated favorable effects such as a reduction in body weight and waist circumference and an improvement in metabolic factors (cholesterol, triglycerides, glycemia etc. Therefore, the antagonism of the endocannabinoid (EC system, if recent data can be confirmed, could be a new treatment target for high risk overweight or obese patients. Obesity is a growing problem that has epidemic proportions worldwide and is associated with an increased risk of premature death (1-3. Individuals with a central deposition of fats have elevated cardiovascular morbidity and mortality (including stroke, heart failure and myocardial infarction and, because of a growing prevalence not only in adults but also in adolescents, it was reclassified in AHA guidelines as a “major modifiable risk factor” for coronary heart disease (4, 5. Although first choice therapy in obesity is based on correcting lifestyle (diet and physical activity in patients with abdominal obesity and high cardiovascular risk and diabetes, often it is necessary to use drugs which reduce the risks. The EC system represents a new target for weight control and the improvement of lipid and glycemic metabolism (6, 7. (Heart International 2007; 3: 27-34

    Dark chocolate may have blood pressure-lowering properties. We conducted a prospective randomized open-label blinded end-point design trial to study a potential dose dependency of the presumed antihypertensive effect of dark chocolate by directly comparing low vs. higher doses of dark chocolate over the course of 3 months. We enrolled a total of 102 patients with prehypertension/stage 1 hypertension and established cardiovascular end-organ damage or diabetes mellitus. Patients were randomly assigned to receive either 6 or 25 g/day of flavanol-rich dark chocolate for 3 months. The difference in 24-h mean blood pressure between groups was defined as the primary outcome measure. Significant reductions in mean ambulatory 24-h blood pressure were observed between baseline and follow-up in both groups (6 g/day: -2.3 mm Hg, 95% confidence interval -4.1 to -0.4; 25 g/day: -1.9 mm Hg, 95% confidence interval -3.6 to -0.2). There were no significant differences in blood pressure changes between groups. In the higher-dose group, a slight increase in body weight was noted (0.8 kg, 95% confidence interval 0.06 to 1.6). The findings are consistent with the hypothesis that dark chocolate may be associated with a reduction in blood pressure (BP). However, due to the lack of a control group, confounding may be possible and the results should be interpreted with caution.

  15. The link between chronic kidney disease and cardiovascular disease.

    2014-07-01

    It is well known that patients with chronic kidney disease (CKD) have a strong risk of cardiovascular disease (CVD). However, the excess risk of cardiovascular disease in patients with CKD is only partially explained by the presence of traditional risk factors, such as hypertension and diabetes mellitus. Directory of Open Access Journals (DOAJ), Google Scholar, PubMed, EBSCO and Web of Science has been searched. Chronic kidney disease even in its early stages can cause hypertension and potentiate the risk for cardiovascular disease. However, the practice of intensive blood pressure lowering was criticized in recent systematic reviews. Available evidence is inconclusive but does not prove that a blood pressure target of less than 130/80 mmHg as recommended in the guidelines improves clinical outcomes more than a target of less than 140/90 mmHg in adults with CKD. The association between CKD and CVD has been extensively documented in the literature. Both CKD and CVD share common traditional risk factors, such as smoking, obesity, hypertension, diabetes mellitus, and dyslipidemia. However, cardiovascular disease remains often underdiagnosed und undertreated in patients with CKD. It is imperative that as clinicians, we recognize that patients with CKD are a group at high risk for developing CVD and cardiovascular events. Additional studies devoted to further understand the risk factors for CVD in patients with CKD are necessary to develop and institute preventative and treatment strategies to reduce the high morbidity and mortality in patients with CKD.

    Cardiovascular disease (CVD) risk is substantially increased in subjects with chronic kidney disease (CKD). The Triglycerides (TG) to High-Density Lipoprotein Cholesterol (HDL-C) ratio is an indirect measure of insulin resistance and an independent predictor of cardiovascular risk. No study to date has been performed to evaluate whether the TG/HDL-C ratio predicts CVD risk in patients with CKD. A total of 197 patients (age 53±12 years) with CKD Stages 1 to 5, were enrolled in this longitudinal, observational, retrospective study. TG/HDL-C ratio, HOMA-IR indexes, serum asymmetric dimethyl arginine (ADMA), high sensitivity C-reactive protein (CRP), parathyroid hormone (PTH), calcium, phosphorous, estimated glomerular filtration rate (eGFR), and albumin levels were measured. Flow mediated vasodilatation (FMD) of the brachial artery was assessed by using high-resolution ultrasonography. A total of 11 cardiovascular (CV) deaths and 43 nonfatal CV events were registered in a mean follow-up period of 30 (range 9 to 35) months. Subjects with TG/HDL-C ratios above the median values (>3.29) had significantly higher plasma ADMA, PTH, and phosphorous levels (p=0.04, p=0.02, p=0.01 respectively) and lower eGFR and FMD values (p=0.03, pcardiovascular outcomes [HR: 1.36 (1.11-1.67) (p=0.003)] along with plasma ADMA levels [HR: 1.31 (1.13-1.52) (p<0.001)] and a history of diabetes mellitus [HR: 4.82 (2.80-8.37) (p<0.001)]. This study demonstrates that the elevated TG/HDL-C ratio predicts poor CVD outcome in subjects with CKD. Being a simple, inexpensive, and reproducible marker of CVD risk, the TG/HDL-C ratio may emerge as a novel and reliable indicator among the many well-established markers of CVD risk in CKD.

    The present work presents the study of morbidity due to acute respiratory infections (ARI) in areas of the town of Lisa in Ciudad Habana, and Isla Juventud (Cuba), to characterize different aspects of morbidity measured by health care attendance and to measure true morbidity. About 90% of consultations for ARI were first-time consultations, while their ratio to further consultations was 5.3. True morbidity rates (TMR), obtained trough active research, ranged from 110.4 to 163.4 cases per 1000 inhabitants, considerably higher than morbidity rates measured by primary care consultations (MRPCC) in the same time period. The true morbidity index (TMI), as measured by the ratio of the two previous rates, ranged from 5 to 15. A high proportion (47.6%) of cases reported no medical care attendance. These results provide approximate estimates of true morbidity in the study area, and allow the establishment of a new control program, also improving epidemiologic surveillance within primary care activities.

    Atherosclerosis, in turn preceded by endothelial dysfunction, underlies a series of important cardiovascular diseases. Reduced bioavailability of endothelial nitric oxide, by increasing vascular tone and promoting platelet aggregation, leukocyte adhesion, and smooth muscle cell proliferation, plays a key role in the onset of the majority of cardiovascular diseases. In addition, high blood levels of asymmetric dimethylarginine, a potent inhibitor of nitric oxide synthesis, are associated with future development of adverse cardiovascular events and cardiac death. Recent reports have demonstrated that another methylarginine, i.e., symmetric dimethylarginine, is also involved in the onset of endothelial dysfunction and hypertension. Almost a decade ago, prematurity at birth and intrauterine growth retardation were first associated with a potential negative influence on the cardiovascular apparatus, thus constituting risk factors or leading to early onset of cardiovascular diseases. This condition is referred to as cardiovascular perinatal programming. Accordingly, cardiovascular morbidity and mortality are higher among former preterm adults than in those born at term. The aim of this paper was to undertake a comprehensive literature review focusing on cellular and biochemical mechanisms resulting in both reduced nitric oxide bioavailability and increased methylarginine levels in subjects born preterm. Evidence of the involvement of these compounds in the perinatal programming of cardiovascular risk are also discussed.

    Full Text Available Obstructive sleep apnea syndrome (OSAS is defined as repeated episodes of upper airway occlusion during sleep with consequent excessive daytime sleepiness. Recently, relationship has been found between cardiovascular disease and OSAS. Therefore OSAS has become more popular today. OSAS is associated with the pathogenesis of cardiovascular disease. A large number of studies have demonstrated that OSAS is an independent risk factor of cardiovascular morbidity and mortality. Sleep apnea was shown to be associated with hypertension, ischemic heart disease, stroke, pulmonary hypertension, cardiac arrhythmia, and cardiovascular mortality

    Spaceflight causes adaptive changes in cardiovascular function that may deleteriously affect crew health and safety. Over the last three decades, symptoms of cardiovascular changes have ranged from postflight orthostatic tachycardia and decreased exercise capacity to serious cardiac rhythm disturbances during extravehicular activities (EVA). The most documented symptom of cardiovascular dysfunction, postflight orthostatic intolerance, has affected a significant percentage of U.S. Space Shuttle astronauts. Problems of cardiovascular dysfunction associated with spaceflight are a concern to NASA. This has been particularly true during Shuttle flights where the primary concern is the crew's physical health, including the pilot's ability to land the Orbiter, and the crew's ability to quickly egress and move to safety should a dangerous condition arise. The study of astronauts during Shuttle activities is inherently more difficult than most human research. Consequently, sample sizes have been small and results have lacked consistency. Before the Extended Duration Orbiter Medical Project (EDOMP), there was a lack of normative data on changes in cardiovascular parameters during and after spaceflight. The EDOMP for the first time allowed studies on a large enough number of subjects to overcome some of these problems. There were three primary goals of the Cardiovascular EDOMP studies. The first was to establish, through descriptive studies, a normative data base of cardiovascular changes attributable to spaceflight. The second goal was to determine mechanisms of cardiovascular changes resulting from spaceflight (particularly orthostatic hypotension and cardiac rhythm disturbances). The third was to evaluate possible countermeasures. The Cardiovascular EDOMP studies involved parallel descriptive, mechanistic, and countermeasure evaluations.

    The number of patients suffering from cardiovascular diseases increases unproportionally high with the increase of the human population and aging, leading to very high expenses in the public health system. Therefore, the challenge of cardiovascular physics is to develop high-sophisticated methods which are able to, on the one hand, supplement and replace expensive medical devices and, on the other hand, improve the medical diagnostics with decreasing the patient's risk. Cardiovascular physics-which interconnects medicine, physics, biology, engineering, and mathematics-is based on interdisciplinary collaboration of specialists from the above scientific fields and attempts to gain deeper insights into pathophysiology and treatment options. This paper summarizes advances in cardiovascular physics with emphasis on a workshop held in Bad Honnef, Germany, in May 2005. The meeting attracted an interdisciplinary audience and led to a number of papers covering the main research fields of cardiovascular physics, including data analysis, modeling, and medical application. The variety of problems addressed by this issue underlines the complexity of the cardiovascular system. It could be demonstrated in this Focus Issue, that data analyses and modeling methods from cardiovascular physics have the ability to lead to significant improvements in different medical fields. Consequently, this Focus Issue of Chaos is a status report that may invite all interested readers to join the community and find competent discussion and cooperation partners.

    Studies have challenged the appropriateness of accepted blood pressure targets. We hypothesised that different levels of low blood pressure are associated with benefit for some, but harm for other outcomes. In this analysis, we assessed the previously reported outcome data from high-risk patients aged 55 years or older with a history of cardiovascular disease, 70% of whom had hypertension, from the ONTARGET and TRANSCEND trials investigating ramipril, telmisartan, and their combination, with a median follow-up of 56 months. Detailed descriptions of randomisation and intervention have already been reported. We analysed the associations between mean blood pressure achieved on treatment; prerandomisation baseline blood pressure; or time-updated blood pressure (last on treatment value before an event) on the composite outcome of cardiovascular death, myocardial infarction, stroke, and hospital admission for heart failure; the components of the composite outcome; and all-cause death. Analysis was done by Cox regression analysis, ANOVA, and χ(2). These trials were registered with ClinicalTrials.gov, number NCT00153101. Recruitment for ONTARGET took place between Dec 1, 2001, and July 31, 2008. TRANSCEND took place between Nov 1, 2001, and May 30, 2004. 30 937 patients were recruited from 733 centres in 40 countries and followed up for a median of 56 months. In ONTARGET, 25 127 patients known to be tolerant to angiotensin-converting-enzyme (ACE)-inhibitors were randomly assigned after a run-in period to oral ramipril 10 mg/day (n=8407), telmisartan 80 mg/day (n=8386), or the combination of both (n=8334). In TRANSCEND, 5810 patients who were intolerant to ACE-inhibitors were randomly assigned to oral telmisartan 80 mg/day (n=2903) or placebo (n=2907). Baseline systolic blood pressure (SBP) 140 mm Hg or higher was associated with greater incidence of all outcomes compared with 120 mm Hg to less than 140 mm Hg.

    Full Text Available Abstract Background Functional assessments of the heart by dynamic cardiovascular magnetic resonance (CMR commonly rely on (i electrocardiographic (ECG gating yielding pseudo real-time cine representations, (ii balanced gradient-echo sequences referred to as steady-state free precession (SSFP, and (iii breath holding or respiratory gating. Problems may therefore be due to the need for a robust ECG signal, the occurrence of arrhythmia and beat to beat variations, technical instabilities (e.g., SSFP "banding" artefacts, and limited patient compliance and comfort. Here we describe a new approach providing true real-time CMR with image acquisition times as short as 20 to 30 ms or rates of 30 to 50 frames per second. Methods The approach relies on a previously developed real-time MR method, which combines a strongly undersampled radial FLASH CMR sequence with image reconstruction by regularized nonlinear inversion. While iterative reconstructions are currently performed offline due to limited computer speed, online monitoring during scanning is accomplished using gridding reconstructions with a sliding window at the same frame rate but with lower image quality. Results Scans of healthy young subjects were performed at 3 T without ECG gating and during free breathing. The resulting images yield T1 contrast (depending on flip angle with an opposed-phase or in-phase condition for water and fat signals (depending on echo time. They completely avoid (i susceptibility-induced artefacts due to the very short echo times, (ii radiofrequency power limitations due to excitations with flip angles of 10° or less, and (iii the risk of peripheral nerve stimulation due to the use of normal gradient switching modes. For a section thickness of 8 mm, real-time images offer a spatial resolution and total acquisition time of 1.5 mm at 30 ms and 2.0 mm at 22 ms, respectively. Conclusions Though awaiting thorough clinical evaluation, this work describes a robust and

    Cardiovascular disease is the leading killer globally and secondary prevention substantially reduces risk. Uptake of, and adherence to, face-to-face preventive programs is often low. Alternative models of care are exploiting the prominence of technology in daily life to facilitate lifestyle behavior change. To inform the development of a web-based application integrated with the primary care electronic health record, we undertook a collaborative user-centered design process to develop a consumer-focused e-health tool for cardiovascular disease risk reduction. A four-phase iterative process involved ten multidisciplinary clinicians and academics (primary care physician, nurses and allied health professionals), two design consultants, one graphic designer, three software developers and fourteen proposed end-users. This 18-month process involved, (1) defining the target audience and needs, (2) pilot testing and refinement, (3) software development including validation and testing the algorithm, (4) user acceptance testing and beta testing. From this process, researchers were able to better understand end-user needs and preferences, thereby improving and enriching the increasingly detailed system designs and prototypes for a mobile responsive web application. We reviewed 14 relevant applications/websites and sixteen observational and interventional studies to derive a set of core components and ideal features for the system. These included the need for interactivity, visual appeal, credible health information, virtual rewards, and emotional and physical support. The features identified as essential were: (i) both mobile and web-enabled 'apps', (ii) an emphasis on medication management, (iii) a strong psychosocial support component. Subsequent workshops (n=6; 2×1.5h) informed the development of functionality and lo-fidelity sketches of application interfaces. These ideas were next tested in consumer focus groups (n=9; 3×1.5h). Specifications for the application were

    Cardiovascular disease is the leading determinant of mortality and morbidity in women. Functional foods are attracting interest as potential regulators of the susceptibility to disease. Supported by epidemiological evidence, chocolate has emerged as a possible modulator of cardiovascular risk. Chocolate, or cocoa as the natural source, contains flavanols, a subclass of flavonoids. The latter years have witnessed an increasing number of experimental and clinical studies that suggest a protective effect of chocolate against atherogenesis. Oxidative stress, inflammation, and endothelial function define three biological mechanisms that have shown sensitivity to chocolate. Moreover, the consumption of chocolate has been involved in the protective modulation of blood pressure, the lipid profile, the activation of platelets, and the sensitivity to insulin. Dark chocolate seems more protective than milk or white chocolate. Despite this array of benefits, there is a lack of well designed clinical studies demonstrating cardiovascular benefit of chocolate. The high caloric content of chocolate, particularly of some less pure forms, imposes caution before recommending uncontrolled consumption. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

    The burnout syndrome denotes a constellation of physical fatigue, emotional exhaustion, and cognitive weariness resulting from chronic stress. Although it overlaps considerably with chronic fatigue as defined in internal medicine, its links with physical illness have not been systematically investigated. This exploratory study, conducted among 104 male workers free from cardiovascular disease (CVD), tested the association between burnout and two of its common concomitants--tension and listlessness--and cardiovascular risk factors. After ruling out five possible confounders (age, relative weight, smoking, alcohol use, and sports activity), the authors found that scores on burnout plus tension (tense-burnout) were associated with somatic complaints, cholesterol, glucose, triglycerides, uric acid, and, marginally, with ECG abnormalities. Workers scoring high on tense-burnout also had a significantly higher low density lipoprotein (LDL) level. Conversely, scores on burnout plus listlessness were significantly associated with glucose and negatively with diastolic blood pressure. The findings warrant further study of burnout as a predictor of cardiovascular morbidity and mortality.

    Full Text Available Vassilis Fragoulakis, Georgia Kourlaba, Nikolaos ManiadakisDepartment of Health Services and Management, National School of Public Health, Athens, GreeceBackground: An economic evaluation was undertaken in order to assess several therapeutic alternatives (rosuvastatin, atorvastatin, simvastatin, and pravastatin for the prevention of primary and secondary cardiovascular events in high-risk patients in Greece.Methods: A probabilistic Markov model with five distinct states provided estimates over a 20-year time span. The relative effectiveness of comparators was based on the literature. The HellenicSCORE risk equation was used to forecast survival. The transition probabilities from acute myocardial infarction or stroke to death were estimated with reference to the Framingham study. In addition, Framingham scores were used to calculate the probability of nonfatal acute myocardial infarction or nonfatal stroke. Costs were estimated from the perspective of sickness funds and included direct medical costs valued in the year 2012. The total treatment cost accounted for the cost of drugs, routine examinations, and resources expended in the management of acute myocardial infarction, stroke, and death. The utility decrements used are those for the Greek population. A supplementary budget impact analysis was also conducted.Results: The mean discounted quality-adjusted life years in the case of males for the rosuvastatin arm were 10.18 versus 10.04, 9.94, and 9.88 for atorvastatin, simvastatin, and pravastatin, respectively. The mean total cost was €15,392, €16,438, €17,009, and €17,356 for rosuvastatin, atorvastatin, simvastatin, and pravastatin, respectively. Similar results were obtained in the case of females, while all analyses demonstrated a statistically significant difference at the 95% level of significance.

    The cardiovascular system is susceptible to a group of diseases that are responsible for a larger proportion of morbidity and mortality than any other disease. Many cardiovascular diseases are associated with a failure of defenses against oxidative stress-induced cellular damage and/or death, leading to organ dysfunction. The pleiotropic transcription factor, nuclear factor-erythroid (NF-E) 2-related factor 2 (Nrf2), regulates the expression of antioxidant enzymes and proteins through the antioxidant response element. Nrf2 is an important component in antioxidant defenses in cardiovascular diseases such as atherosclerosis, hypertension, and heart failure. Nrf2 is also involved in protection against oxidant stress during the processes of ischemia-reperfusion injury and aging. However, evidence suggests that Nrf2 activity does not always lead to a positive outcome and may accelerate the pathogenesis of some cardiovascular diseases (e.g., atherosclerosis). The precise conditions under which Nrf2 acts to attenuate or stimulate cardiovascular disease processes are unclear. Further studies on the cellular environments related to cardiovascular diseases that influence Nrf2 pathways are required before Nrf2 can be considered a therapeutic target for the treatment of cardiovascular diseases.

    Cardiovascular diseases (CVDs) represent a major Public Health burden. High serum cholesterol levels have been linked to major CV risk. The objectives of this study were to review the epidemiology of hypercholesterolemia in high risk CV patients from Spain, by assessing its prevalence, the proportion of diagnosed patients undergoing pharmacological treatment and the degree of attained lipid control. A systematic literature review was carried out using Medline and two Spanish databases. Manuscripts containing information on hypercholesterolemia in several high CV risk groups [diabetes mellitus (DM), Systematic COronary Risk Evaluation (SCORE) risk >5, or documented CVD], published between January 2010 and October 2014, were included. Of the 1947 published references initially retrieved, a full-text review was done on 264 manuscripts and 120 were finally included. Prevalence of hypercholesterolemia ranged from 50 to 84% in diabetics, 30-60% in patients with DM or elevated SCORE risk, 64-74% with coronary heart disease, 40-70% in stroke patients, and 60-80% in those with peripheral artery disease. Despite the finding that most of them were on pharmacological treatment, acceptable control of serum lipids was very variable, ranging from 15% to 65%. Among those with heterozygous familial hypercholesterolemia, 95-100% received treatment but less than 50% achieved their therapeutic goals. An elevated prevalence of hypercholesterolemia can be found in targeted groups at high CV risk. Although most patients are receiving pharmacological treatment, rates of lipid control continue to be low, both in primary and secondary prevention.

    It has been demonstrated that an elevated ratio of triglycerides (TG) to high-density lipoprotein cholesterol (HDL-C) is a risk factor of coronary artery disease (CAD) in patients with type 2 diabetes mellitus (T2DM) and is also found to be associated with cardiovascular events (CVEs) in the general population. However, its prognostic value in patients with T2DM along with CAD remains to be determined. A total of 1,447 consecutive patients with T2DM with angiographic-proven stable CAD were enrolled in the present study and followed-up for an average of 20.3 months. The characteristics of all patients including fasting lipid profile were obtained at baseline and multivariate Cox proportional hazards models were constructed using log TG/HDL-C as a predictor variable. The relationships between CVEs and total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), non-HDL-C, TC/HDL-C, LDL-C/HDL-C and apolipoprotein B/ apolipoprotein AI (apoB/apoAI) were also explored. Compared with patients without CVEs, the ones who experienced CVEs had a higher TG/HDL-C ratio. Univariable regression revealed a significant association of log TG/HDL-C with CVEs (hazard ratio = 2.5, P = 0.015). After adjusting for multiple traditional risk factors of cardiovascular disease, the association was still found (hazard ratio = 2.47, P = 0.047). Moreover, results suggested that the ratios of non-HDL-C, TC/HDL-C, LDL-C/HDL-C and apoB/apoAI were not predictors for CVEs in T2DM. In our primary study, data suggested that elevated TG/HDL-C value might be a useful predictor for future CVEs in Chinese patients with T2DM with stable CAD. Further study is needed to confirm our findings. Copyright © 2017 Southern Society for Clinical Investigation. Published by Elsevier Inc. All rights reserved.

    Urocortin and other hypothalamus corticotropin-releasing factor (CRF) polypeptides play biologically diverse roles in the stress, cardiovascular and inflammatory responses by acting on central and peripheral CRF receptors.Urocortin shows a significantly high sequence homology to CRF, and the concurrent expression of type-2 CRF (CRF2) receptors with urocortin in the heart suggests that urocortin may play a physiological role in the cardiac function. Urocortin is thought to be the endogenous agonist producing the cardiovascular actions previously attributed to CRF. This review highlights the current novel findings on the molecular and cellular mechanisms by which urocortin may exert its cardiovascular protective action.

    High altitude constitutes an exciting natural laboratory for medical research. Although initially, the aim of high-altitude research was to understand the adaption of the organism to hypoxia and find treatments for altitude-related diseases, during the past decade or so, the scope of this research has broadened considerably. Two important observations led the foundation for the broadening of the scientific scope of high-altitude research. First, high-altitude pulmonary edema represents a unique model that allows studying fundamental mechanisms of pulmonary hypertension and lung edema in humans. Second, the ambient hypoxia associated with high-altitude exposure facilitates the detection of pulmonary and systemic vascular dysfunction at an early stage. Here, we will review studies that, by capitalizing on these observations, have led to the description of novel mechanisms underpinning lung edema and pulmonary hypertension and to the first direct demonstration of fetal programming of vascular dysfunction in humans.

    In the developed world, HIV infection is now well managed with very effective and less toxic antiretroviral treatment. HIV-positive patients therefore are living longer, but are now faced by challenges associated with aging. Several non-AIDS associated morbidities are increased in this population......, including cardiovascular disease (CVD). It is suggested that CVD occurs earlier among HIV-positive patients compared with HIV-negative patients, and at a higher rate. Several factors have been proposed to contribute to this. First, the traditional CVD risk factors are highly prevalent in this population....... High rates of smoking, dyslipidaemia and a family history of CVD have been reported. This population is also aging, with estimates of more than 25% of HIV-positive patients in the developed world being over the age of 50. Antiretroviral treatment, both through its effect on lipids and through other...

    Morbidly obese patients are at risk of developing insulin resistance and cardiovascular disease. Low-grade systemic inflammation is an important factor for this development. We evaluated the effect of bariatric surgery on markers of inflammation, coagulation and glucose metabolism. Ninety-seven morbidly obese patients and 17 lean subjects (control group) participated. Anthropometric measurements as well as fasting blood samples were obtained at first admission, prior to surgery, and 1 year after surgery. At admission, the morbidly obese group had significantly elevated levels of the complement components C3 and C4 compared to the lean control group (P<0.0001). Levels of C3 and C4 dropped significantly in the morbidly obese group over time (P<0.0001), and, 1 year after the operation, levels were comparable to those of the control group. The same changes were seen for markers of inflammation (high-sensitivity C-reactive protein, tumor necrosis factor-α, interferon-γ, interleukin-1 receptor antagonist, IL-6, and IL-13), coagulation (fibrinogen and plasminogen activator inhibitor-1), and glucose metabolism (leptin and insulin). There was a positive correlation between changes in C3 and body mass index, weight, coagulation parameters, inflammatory parameters, and leptin, respectively. Bariatric surgery in morbidly obese patients reduced weight effectively. Even more importantly, the increased levels of several risk factors associated with diabetes and cardiovascular co-morbidity normalized 1 year after surgery.

    Full Text Available Background/Aims. Arterial stiffness is an independent risk factor for cardiovascular morbidity and mortality. This study was conducted to determine the effect of olmesartan (OLM and azelnidipine (AZL on arterial stiffness using the cardio-ankle vascular index (CAVI, which is a novel blood pressure (BP-independent marker for arterial stiffness in hypertensive patients. Methods. Fifty-two consecutive hypertensive patients were randomly assigned either to a group treated with OLM monotherapy or to a group treated with OLM and AZL combination therapy. Clinical and biological parameters were measured before and 12 months after the start of this study. Results. Both therapies significantly and similarly reduced BP, augmentation index, and plasma aldosterone levels. The combination therapy significantly decreased CAVI and serum low-density lipoprotein (LDL-C levels and these reductions were significantly greater than those produced with monotherapy. No significant differences in metabolic parameters were observed between the two therapies. Conclusion. The combination therapy with OLM and AZL had beneficial effects on arterial stiffness assessed by CAVI, LDL-C, and metabolism, despite the similar BP reduction, compared with OLM monotherapy. Since these markers are known to influence the future risk of cardiovascular events, combination therapy with OLM and AZL could be a useful choice for treating hypertensive patients.

    Although for most children the process of atherosclerosis is subclinical, dramatically accelerated atherosclerosis occurs in some pediatric disease states, with clinical coronary events occurring in childhood and very early adult life. As with most scientific statements about children and the future risk for cardiovascular disease, there are no randomized trials documenting the effects of risk reduction on hard clinical outcomes. A growing body of literature, however, identifies the importance of premature cardiovascular disease in the course of certain pediatric diagnoses and addresses the response to risk factor reduction. For this scientific statement, a panel of experts reviewed what is known about very premature cardiovascular disease in 8 high-risk pediatric diagnoses and, from the science base, developed practical recommendations for management of cardiovascular risk.

    A decreased inotropic effect of myocardial beta receptor agonists in animals receiving diets high in unsaturated fats (UNSAT) has been demonstrated. The effect of an UNSAT diet on myocardial systolic performance under different loading conditions, in the presence of intact cardiovascular reflexes, has not been examined. We investigated the effect of an UNSAT diet on preload recruitable stroke work (SW) in the anaesthetised, open chest, ventilated rat. A control (CONTROL, 11% by energy), a high saturated fat (SAT, 37% by energy) and a high UNSAT (37% by energy) diet were fed to three groups of rats. At three months, systolic myocardial performance (stroke work: SW) at increasing left ventricular end diastolic pressures (LVEDP) was measured within a physiological preload range. There were no significant differences in either the slope or the intercept of the LVEDP/SW relation were found between the three diet groups. Systemic vascular resistance and heart rate decreased to the same extent in the three diet groups over the range of preloads examined. This occurred as a consequence of intact baroreceptor reflexes. Hence dietary modulation of unsaturated fats does not influence myocardial contraction over a wide range of physiological preloads in the presence of intact baroreceptor reflexes.

    This study investigates the psychological profiles of highly stressed medical technologists. One hundred and four individuals representing a cross-section of the United States who function as operators of heart-lung machines during open heart surgery (perfusionists) were studied using both internal and external models based on the works of Eric Berne and Karen Horney. Daily exposure to life and death responsibilities combined with the constant pressures of maintaining current technical skills can make the profession selected for this study representative of high technology professions that require a great deal of coping. Results of this study indicate that there is a balanced psychological profile in successful technologists functioning in long-term, high-stressed occupations. Female perfusionists appear to be more aggressive and critical than their male counterparts. This is seen as an attempt by female perfusionists to compensate for what has historically been a male dominanted, highly technical and high-stressed occupation. Generalizations for candidate selections to high stressed occupations could be made as well as projections of foundations for possible progressive disillusionment (burn out).

    Full Text Available Purpose. To determine clinical, biochemical, and pharmacological characteristics as well as cardiovascular disease prevalence and its associated factors among end-stage kidney disease patients receiving hemodialysis in the main hemodialysis center in Lima, Peru. Methods. This cross-sectional study included 103 patients. Clinical charts were reviewed and an echocardiogram was performed to determine prevalence of cardiovascular disease, defined as the presence of systolic/diastolic dysfunction, coronary heart disease, ventricular dysrhythmias, cerebrovascular disease, and/or peripheral vascular disease. Associations between cardiovascular disease and clinical, biochemical, and dialysis factors were sought using prevalence ratio. A robust Poisson regression model was used to quantify possible associations. Results. Cardiovascular disease prevalence was 81.6%, mainly due to diastolic dysfunction. It was significantly associated with age older than 50 years, metabolic syndrome, C-reactive protein levels, effective blood flow ≤ 300 mL/min, severe anemia, and absence of mild anemia. However, in the regression analysis only age older than 50 years, effective blood flow ≤ 300 mL/min, and absence of mild anemia were associated. Conclusions. Cardiovascular disease prevalence is high in patients receiving hemodialysis in the main center in Lima. Diastolic dysfunction, age, specific hemoglobin levels, and effective blood flow may play an important role.

    Full Text Available Primary prevention of diabetes in persons with high cardiovascular risk is an actual problem. Results of DREAM trial are discussed. Influence of ACE inhibitor, ramipril, on risk of diabetes onset in patients with pre-diabetes and low cardiovascular risk is focused. Metabolic effects of other groups of antihypertensive drugs and their ability to prevent diabetes onset are compared. Ramipril three years therapy resulted in normalization in glucose level but did not have effect on frequency of diabetes onset. Change in life-style and regular usage of ACE inhibitor, ramipril, can contribute in normalization of glycemia level in patients with combination of pre-diabetes and arterial hypertension.

  11. Telmisartan: a review of its use in cardiovascular disease prevention.

    Frampton, James E

    2011-04-16

    Telmisartan (Micardis®, Pritor®), a well established angiotensin type 1 receptor antagonist, is indicated in the EU for the reduction of cardiovascular morbidity in patients with manifest atherothrombotic cardiovascular disease (CVD) or type 2 diabetes mellitus with documented target organ damage, as well as for the treatment of hypertension. In the pivotal ONTARGET trial, which enrolled ACE inhibitor-tolerant patients at high vascular risk, telmisartan 80 mg once daily added to existing, proven therapy was noninferior to ramipril 10 mg once daily (the gold standard cardioprotective ACE inhibitor) in terms of CVD prevention. Moreover, telmisartan was better tolerated than ramipril, as reflected in, for example, lower incidences of permanent treatment discontinuations due to cough and angioedema. The placebo-controlled TRANSCEND and PRoFESS studies provided supporting evidence for the (time-dependent) effectiveness of telmisartan in preventing cardiovascular events, although the drug appeared to have neither a beneficial nor a harmful impact on cardiovascular mortality. The TRANSCEND trial also demonstrated that telmisartan was well tolerated in ACE inhibitor-intolerant patients at high vascular risk. On the basis of these findings, telmisartan can be considered an effective treatment option for CVD prevention in patients at high vascular risk. Consideration may be given to prescribing the drug as an alternative to ramipril in patients who are able to tolerate ACE inhibitors and, potentially, instead of ramipril in patients who are unable to tolerate ACE inhibitors.

    The effects of high-intensity progressive resistance training (HIPRT) on cardiovascular function and autonomic neural regulation in older adults are unclear. To investigate this issue, 25 older adults were randomly divided into two groups: control (CON, N = 13, 63 ± 4 years; no training) and HIPRT (N = 12, 64 ± 4 years; 2 sessions/week, 7 exercises, 2–4 sets, 10–4 RM). Before and after four months, maximal strength, quadriceps cross-sectional area (QCSA), clinic and ambulatory blood pressures (BP), systemic hemodynamics, and cardiovascular autonomic modulation were measured. Maximal strength and QCSA increased in the HIPRT group and did not change in the CON group. Clinic and ambulatory BP, cardiac output, systemic vascular resistance, stroke volume, heart rate, and cardiac sympathovagal balance did not change in the HIPRT group or the CON group. In conclusion, HIPRT was effective at increasing muscle mass and strength without promoting changes in cardiovascular function or autonomic neural regulation.

    Background Heart disease and stroke mortality and morbidity rates in Arkansas are among the highest in the U.S. While the effect of air pollution on cardiovascular health was identified in traffic-dominated metropolitan areas, there is a lack of studies for populations with variable exposure profiles, demographic and disease characteristics. Objective Determine the short-term effects of air pollution on cardiovascular and respiratory morbidity in the stroke and heart failure belt. Methods We investigated the associations of fine particles and ozone with respiratory and cardiovascular emergency room visits during the 2002–2012 period for adults in Central Arkansas using Poisson generalized models adjusted for temporal, seasonal and meteorological effects. We evaluated sensitivity of the associations to mutual pollutant adjustment and effect modification patterns by sex, age, race and season. Results We found effects on cardiovascular and respiratory emergencies for PM2.5 (1.52% [95%CI: −1.10, 4.20]; 1.45% [95%CI: −2.64, 5.72] per 10 μg/m3) and O3 (0.93% [95%CI: −0.87, 2.76]; 0.76 [95%CI: −1.92, 3.52] per 10 ppbv) during the cold period (October–March). The effects were stronger among whites, except for the respiratory effects of O3 that were higher among Blacks/African-Americans. Effect modification patterns by age and sex differed by association. Both pollutants were associated with increases in emergency room visits for hypertension, heart failure and asthma. Effects on cardiovascular and respiratory emergencies were observed during the cold period when particulate matter was dominated by secondary nitrate and wood burning. Conclusion Outdoor particulate pollution during winter had an effect of cardiovascular morbidity in central Arkansas, the region with high stroke and heart disease incidence rates. PMID:26232212

    Cardioplegic reperfusion during a long term ischemic period interrupts cardiac surgery and also increases cellular edema due to repeated solution administration. We reviewed the clinical experiences on myocardial protection of a single perfusion with histidine-tryptophan-ketoglutarate (HTK) for high-risk patients with severe pulmonary arterial hypertension associated with complex congenital heart disease. This retrospective study included 101 high-risk patients undergoing arterial switch operation between March 2001 and July 2012. We divided the cohort into two groups: HTK group, myocardial protection was carried out with one single perfusion with HTK solution; and St group, myocardial protection with conventional St. Thomas' crystalloid cardioplegic solution. The duration of cardiopulmonary bypass did not differ between the two groups. The mortality, morbidity, ICU stay, post-operative hospitalization time, and number of transfusions in HTK group were lower than those in St group (P<0.05). Univariate and multivariate analysis showed that HTK is a statistically significant independent predictor of decreased early mortality and morbidity (P<0.05). In conclusion, HTK solution seems to be an effective and safe alternative to St. Thomas' solution for cardioplegic reperfusion in high-risk patients with complex congenital heart disease.

    Purpose of Review Chronic sarcoidosis is a complex disease with numerous comorbid conditions and can be fatal in some cases. Recognizing causes of morbidity and mortality is important to effectively select treatments, manage symptoms, and improve outcomes. The purpose of this review is to examine emerging knowledge on morbidity and mortality in sarcoidosis. Recent Findings Approximately one to five percent of patients with sarcoidosis die from complications of sarcoidosis. Recent population studies indicate that mortality may be increasing over the past decade. The reasons behind these trends are unclear, but could include increasing incidence, detection rates, severity of disease, or age of the population. Morbidity of sarcoidosis is reflected by a trend of increased hospitalizations over recent years and increased use of healthcare resources. Morbidity can be caused by organ damage from granulomatous inflammation, treatment complications, and psychosocial effects of the disease. Recent studies are focused on morbidity related to cardiopulmonary complications, bone health, and aging within the sarcoidosis population. Last, sarcoidosis is associated with autoimmune diseases, pulmonary embolism, and malignancy; however, the underlying mechanisms linking diseases continue to be debated. Summary Morbidity in sarcoidosis is significant and multifactorial. Mortality is infrequent, but may be increasing over the years. PMID:25029298

    Screening for chronic kidney disease is recommended in people at high risk, but data on the independent and combined associations of estimated glomerular filtration rate (eGFR) and albuminuria with all-cause and cardiovascular mortality are limited. To clarify this, we performed a collaborative meta-analysis of 10 cohorts with 266,975 patients selected because of increased risk for chronic kidney disease, defined as a history of hypertension, diabetes, or cardiovascular disease. Risk for all-cause mortality was not associated with eGFR between 60-105 ml/min per 1.73 m², but increased at lower levels. Hazard ratios at eGFRs of 60, 45, and 15 ml/min per 1.73 m² were 1.03, 1.38 and 3.11, respectively, compared to an eGFR of 95, after adjustment for albuminuria and cardiovascular risk factors. Log albuminuria was linearly associated with log risk for all-cause mortality without thresholds. Adjusted hazard ratios at albumin-to-creatinine ratios of 10, 30 and 300 mg/g were 1.08, 1.38, and 2.16, respectively compared to a ratio of five. Albuminuria and eGFR were multiplicatively associated with all-cause mortality, without evidence for interaction. Similar associations were observed for cardiovascular mortality. Findings in cohorts with dipstick data were generally comparable to those in cohorts measuring albumin-to-creatinine ratios. Thus, lower eGFR and higher albuminuria are risk factors for all-cause and cardiovascular mortality in high-risk populations, independent of each other and of cardiovascular risk factors.

    2010-08-01

    Whereas developed nations have witnessed a drop in the occurrence and mortality of ischemic heart disease, developing nations have recorded a constant rise. The burden of cardiovascular disease risk factors may explain this increase. We conducted a population-based cross-sectional survey to estimate the prevalence of cardiovascular risk factors in the population protected by the Mexican Social Security Institute. A total of 20,062 Mexicans, aged >or=20 years, 43.5% (8,727) male and 56.5% (11,335) female, randomly selected in a 4-stage stratified population-based sampling process were included. The most prevalent cardiovascular risk factor in men was smoking (31.9%), whereas in women, it was obesity (26.6%) and central obesity (49.7%). A similar high age-adjusted prevalence was observed in women and men for hypertension (29.7% and 28.8%), diabetes (12.94% and 12.66%), and hypercholesterolemia (13.81% and 12.36%). There was a clear age effect on the prevalence of diabetes, hypertension, and hypercholesterolemia, with increasing prevalence with aging. Smoking also had an age effect, but its prevalence increases as age diminishes. More than half of the subjects in reproductive age (20-44 years old) have at least 1 cardiovascular risk factor, mainly smoking. Cardiovascular risk factors are highly prevalent in the Mexican population, which seems to be between the second and third stages of the tobacco epidemic. The increased prevalence of risk factors clustering indicates the need for comprehensive integrated management of cardiovascular risk factors in Mexicans, with special emphasis on individuals at younger ages.

    As glucagon-like peptide-1 receptor agonists lower blood pressure (BP) in type 2 diabetes mellitus (T2DM), we examined BP control in relation to targets set by international bodies prior to randomization in the Liraglutide Effect and Action in Diabetes: Evaluation of cardiovascular outcome Results (LEADER) trial. We analyzed baseline data from LEADER (NCT01179048), an ongoing phase 3B, randomized, double-blind, placebo-controlled cardiovascular outcomes trial examining the cardiovascular safety of the glucagon-like peptide-1 receptor agonist liraglutide in 9340 people with T2DM from 32 countries [age (all mean ± SD) 64 ± 7.2 years, BMI 32.5 ± 6.3 kg/m, duration of diabetes 12.7 ± 8.0 years], all of whom were at high risk for cardiovascular disease (CVD). A total of 81% (n = 7592) of participants had prior CVD and 90% (n = 8408) had a prior history of hypertension. Despite prescription of multiple antihypertensive agents at baseline, only 51% were treated to a target BP of less than 140/85 mmHg and only 26% to the recommended baseline BP target of less than 130/80 mmHg. In univariate analyses, those with prior CVD were prescribed more agents (P high cardiovascular risk, particularly outside North America. Longitudinal data from the LEADER trial may provide further insights into BP control in relation to cardiovascular outcomes in this condition.

    Evolocumab (AMG 145), a fully human monoclonal antibody against PCSK9, significantly reduced low-density lipoprotein cholesterol (LDL-C) levels in phase 2 and 3 studies. This phase 3 study evaluated the efficacy and safety of evolocumab plus atorvastatin in Japanese patients with hyperlipidemia or mixed dyslipidemia and high cardiovascular risk. Patients were randomized to atorvastatin 5 or 20 mg/day for 4 weeks. Subsequently, patients underwent second randomization to evolocumab 140 mg biweekly (Q2W) or 420 mg monthly (QM) or placebo Q2W or QM. Coprimary end points were % change from baseline in LDL-C at week 12 and mean of weeks 10 and 12. Secondary end points included change and % change in other lipids and proportion of patients reaching LDL-C evolocumab); 39% and 40% were women; 14% and 12% had cerebrovascular or peripheral arterial disease; and 51% and 47% had diabetes. At entry, mean (SD) calculated LDL-C was 128 (23) mg/dL; after stabilization on atorvastatin 5 and 20 mg/day, baseline LDL-C levels were 118 (35) and 94 (24) mg/dL, respectively. Mean LDL-C reductions at week 12 for evolocumab versus placebo ranged from 67% to 76%. No imbalances were observed in adverse events between treatment groups. Efficacy and safety for Q2W or QM evolocumab dosing were similar. In conclusion, in high-risk Japanese patients receiving stable statin therapy, evolocumab markedly reduced LDL-C and was well tolerated.

    The continuing increase in the prevalence of obesity and metabolic disorders such as type-II diabetes and an accelerating aging population globally will remain the major contributors to cardiovascular mortality and morbidity in the 21st century. It is well known that aging is highly associated with metabolic and cardiovascular diseases. Growing evidence also shows that obesity and metabolic diseases accelerate aging process. Studies in experimental animal models demonstrate similarity of metabolic and cardiovascular phenotypes in metabolic diseases and old age, e.g. insulin resistance, oxidative stress, chronic low grade inflammation, cardiac hypertrophy, cardiac fibrosis, and heart failure, as well as vascular dysfunctions. Despite intensive research, the molecular mechanisms linking metabolic stress, aging, and ultimately cardiovascular diseases are still elusive. Although the mammalian target of rapamycin (mTOR) signalling is a well known regulator of metabolism and lifespan in model organisms, its central role in linking metabolic stress, aging and cardiovascular diseases is recently emerging. In this article, we review the evidence supporting the role of mTOR signalling as a molecular interface connecting metabolic stress, aging and cardiovascular diseases. The therapeutic potentials of targeting mTOR signalling to protect against metabolic and age-associated cardiovascular diseases are discussed. © 2012 The Authors. obesity reviews © 2012 International Association for the Study of Obesity.

    This analysis evaluated the hypothesis that the plasma triglyceride (TG)/high-density lipoprotein cholesterol (HDL-C) concentration ratio can help identify patients with essential hypertension who are insulin-resistant, with the cardiovascular disease (CVD) risk profile associated with that defect. Data from a community-based study developed between 2003 and 2012 were used to compare CVD risk factors and outcome. Plasma TG/HDL-C cut-points of 2.5 (women) and 3.5 (men) subdivided normotensive (n = 574) and hypertensive (n = 373) subjects into "high" and "low" risk groups. Metabolic syndrome criteria (MetS) were also used to identify "high" and "low" risk groups. The baseline cardio-metabolic profile was significantly more adverse in 2003 in "high" risk subgroups, irrespective of BP classification or definition of risk (TG/HDL-C ratio vs. MetS criteria). Crude incidence of combined CVD events increased across risk groups, ranging from 1.9 in normotensive-low TG/HDL-C subjects to 19.9 in hypertensive-high TG/HDL-C ratio individuals (P for trends <.001). Adjusted hazard ratios for CVD events also increased with both hypertension and TG/HDL-C. Comparable findings were seen when CVD outcome was predicted by MetS criteria. The TG/HDL-C concentration ratio and the MetS criteria identify to a comparable degree hypertensive subjects who are at greatest cardio-metabolic risk and develop significantly more CVD.

  15. High-density lipoproteincholesterol, reverse cholesterol transport, and cardiovascular risk: a tale of genetics?

    Directory of Open Access Journals (Sweden)

    Full Text Available Cholesterol deposition plays a central role in atherogenesis. The accumulation of lipid material is the result of an imbalance between the influx and efflux of cholesterol within the arterial wall. High levels of plasma low-density lipoprotein-cholesterol are considered the major mechanism responsible for the influx and accumulation of cholesterol in the arterial wall, while high-density lipoprotein (HDL- cholesterol seems responsible for its efflux. The mechanism by which cholesterol is removed from extra-hepatic organs and delivered to the liver for its catabolism and excretion is called reverse cholesterol transport (RCT. Epidemiological evidence has associated high levels of HDL-cholesterol/ApoA-I with protection against atherosclerotic disease, but the ultimate mechanism(s responsible for the beneficial effect is not well established. HDLs are synthesized by the liver and small intestine and released to the circulation as a lipid-poor HDL (nascent HDL, mostly formed by ApoA-I and phospholipids. Through their metabolic maturation, HDLs interact with the ABCA1 receptor in the macrophage surface increasing their lipid content by taking phospholipids and cholesterol from macrophages becoming mature HDL. The cholesterol of the HDLs is transported to the liver, via the scavenger receptor class B, type I, for further metabolization and excretion to the intestines in the form of bile acids and cholesterol, completing the process of RCT. It is clear that an inherited mutation or acquired abnormality in any of the key players in RCT mat affect the atherosclerotic process.

    Full Text Available Research Question: What is the sickness prevalence in the slums of a metropolitan city? Objectives: To estimate the morbidity prevalence with reference to a socio-economic and demographic perspective of the slum population of Delhi. Study Design: A cross-sectional study was conducted and data were collected by a two-stage random sampling method. In the first stage, slum locations were selected and in the second stage households were selected. Participants: Data were collected from 1049 households consisting of 5358 individuals′ information. Results: The overall morbidity prevalence is 15.4%. It is 14.7 and 16.3% for males and females, respectively but the differences are not statistically significant. The reported higher morbidity prevalence and the illiteracy status are significantly associated. Diseases of the respiratory system appear to be very high among slum dwellers. Conclusion: From this study, it can be concluded that the number of years of staying in the slum area, presence of a separate kitchen, type of house, it being Pucca or Kuccha, types of toilet pits or open defecation are the important environmental factors for the reports of higher morbidity patterns from the slum area.

    Full Text Available Background & objectives: Non-alcoholic fatty liver disease (NAFLD is an important cause of elevated liver functions. There is evidence showing an association between NAFLD and subclinical atherosclerosis independent of traditional risk factors. We undertook this retrospective study to determine the association of Framingham cardiovascular risk scoring system with liver function tests and inflammatory markers and to find the role of liver function tests in determination of CVD risk among non-obese and non-diabetic subjects with non-alcoholic fatty liver disease. Methods: A total of 2058 patients were included in the study. Framingham cardiovascular risk scoring was done of all patients according to the age, gender, systolic blood pressure, serum total cholesterol and HDL cholesterol levels, smoking and antihypertensive medication history. Liver function test, lipid profile, insulin, uric acid, ferritin levels, etc. were determined. Results: According to the ultrasonography findings, patients were grouped as without any fatty infiltration of the liver (control group (n=982, mild (n= 473, moderate (n=363 and severe fatty liver disease (n= 240 groups. In severe fatty liver disease group, the mean Framingham cardiovascular risk score was significantly higher than that of other groups. t0 here was a positive correlation between GGT, uric acid and ferritin levels with Framingham cardiovascular score. In multivariate analysis, high GGT levels were positively associated with high-risk disease presence (OR: 3.02, 95% CI: 2.62-3.42 compared to low GGT levels independent of the age and sex. Interpretation & conclusions: Cardiovascular disease risk increases with the presence and stage of fatty liver disease. Our findings showed a positive correlation between elevated GGT levels and Framingham cardiovascular risk scoring system among non-diabetic, non-obese adults which could be important in clinical practice. Though in normal limits, elevated GGT levels

    This pilot study compared placental growth factor (PIGF) levels in populations with high versus low risk for cardiovascular disease. Previous experiments from our laboratory (Sundaresan et al. 2005, 2009) revealed that the angiogenic factor PIGF was up regulated in modeled microgravity conditions in human lymphocytes leading to possible atherogenesis and pathogenesis in microgravity. Since the findings came from microgravity analog experiments, there is a strong link to its usefulness in the microgravity field as a biomarker. It is important to understand, that these findings came from both studies on expression levels of this cardiovascular marker in human lymphocytes in microgravity ( in vitro microgravity analog), and a follow up gene expression study in hind limb suspended mice ( in vivo microgravity analog). The relevance is enhanced because in life on earth, PIGF is an inflammatory biomarker for cardiovascular disease. Studies on the levels of PIGF would help to reduce the risk and prevention of heart failures in astronauts. If we can use this marker to predict and reduce the risk of cardiac events in astronauts and pilots, it would significantly help aerospace medicine operations. The investigations here confirmed that in a cardiovascular stressed population such as coronary artery disease (CAD) and acute coronary syndrome (ACS) patients, PIGF could be overexpressed. We desired to re-evaluate this marker in patients with cardiovascular disease in our own study. PIGF is a marker of inflammation and a predictor of short-term and long-term adverse outcome in ACS. In addition, elevated PIGF levels may be associated with increased risk for CAD.PIGF levels were determined in thirty-one patients undergoing cardiovascular catheterization for reasons other than ACS and in thirty-three low-risk asymptomatic subjects. Additional data on traditional cardiovascular risk factors for both populations were also compiled and compared. We found that PIGF levels were

    Full Text Available The paper evaluates the impact of hormone replacement therapy (HRT with androgens on cardiac metabolic indicators in men with high cardiovascular risk (CVR and androgen deficiency state. An open-label randomized clinical trial enrolled 52 men aged 30–64 years with high CVR and detected androgen-deficiency state. The men were randomized into 2 groups: a control group (CG (n = 26 continued to receive the pre-trial therapy; during the previous therapy, a study group (SG (n = 26 had daily applications of transdermal gel with testosterone (AndroGel in a daily dose of 50 mg of testosterone in 5 g of the gel. The trial lasted 180 days. The changes in the indicators under study were traced 90 days after treatment initiation at an intermediate visit and 180 days after the initiation of treatment – at the end of its treatment.At the end of the trial, HRT in men with androgen deficiency and high CVR led to normalization of testosterone levels in all the SG patients and to improvement in erectile function by 12 %. Androgen therapy caused a statistically significant reduction in blood pressure by 10 %; no changes were virtually observed in the CG. HRT promoted a slight, but significant weight loss (by an average of 2.8 kg and waist circumference (by an average of 1.7 cm. The therapy performed also lowered the concentration of total cholesterol by an average of 11 % and that of triglycerides by 22 %. During the therapy, there was a significant decrease in fasting insulin and glucose levels. Overall, the course therapy with transdermal gel in combination with testosterone resulted in a reduction in the expected total CVR by 30 %. Thus, HRT using testosterone preparations in men with hypogonadism and high CVR led to normalization of testosterone levels and major cardiac metabolic indicators and to improvement in erectile function.

Thus, HRT using testosterone preparations in men with hypogonadism and high CVR led to normalization of testosterone levels and major cardiac metabolic indicators and to improvement in erectile function.

    Full Text Available Background: To evaluate agreement between cardiovascular risk in sedentary patients as estimated by the new Framingham-D’Agostino scale and by the SCORE chart, and to describe the patient characteristics associated with the observed disagreement between the scales. Design: A cross-sectional study was undertaken involving a systematic sample of 2,295 sedentary individuals between 40–65 years of age seen for any reason in 56 primary care offices. An estimation was made of the Pearson correlation coefficient and kappa statistic for the classification of high risk subjects (≥20% according to the Framingham-D’Agostino scale, and ≥5% according to SCORE. Polytomous logistic regression models were fitted to identify the variables associated with the discordance between the two scales. Results: The mean risk in males (35% was 19.5% ± 13% with D’Agostino scale, and 3.2% ± 3.3% with SCORE. Among females, they were 8.1% ± 6.8% and 1.2% ± 2.2%, respectively. The correlation between the two scales was 0.874 in males (95% CI: 0.857–0.889 and 0.818 in females (95% CI: 0.800–0.834, while the kappa index was 0.50 in males (95% CI: 0.44%–0.56% and 0.61 in females (95% CI: 0.52%–0.71%. The most frequent disagreement, characterized by high risk according to D’Agostino scale but not according to SCORE, was much more prevalent among males and proved more probable with increasing age and increased LDL-cholesterol, triglyceride and systolic blood pressure values, as well as among those who used antihypertensive drugs and smokers. Conclusions: The quantitative correlation between the two scales is very high. Patient categorization as corresponding to high risk generates disagreements, mainly among males, where agreement between the two classifications is only moderate.

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

    Full Text Available According to guidelines, diabetic patients with high cardiovascular risk should receive a statin. Despite this consensus, fibrate monotherapy is commonly used in this population. We assessed the frequency and clinical consequences of the use of fibrates for primary prevention in patients with diabetes and high cardiovascular risk.Retrospective cohort study based on nationwide data from the medical and administrative databases of French national health insurance systems (07/01/08-12/31/09 with a follow-up of up to 30 months.Lipid-lowering drug-naive diabetic patients initiating fibrate or statin monotherapy were identified. Patients at high cardiovascular risk were then selected: patients with a diagnosis of diabetes and hypertension, and > 50 (men or 60 (women, but with no history of cardiovascular events. The composite endpoint comprised myocardial infarction, stroke, amputation, or death.Of the 31,652 patients enrolled, 4,058 (12.8% received a fibrate. Age- and gender-adjusted annual event rates were 2.42% (fibrates and 2.21% (statins. The proportionality assumption required for the Cox model was not met for the fibrate/statin variable. A multivariate model including all predictors was therefore calculated by dividing data into two time periods, allowing Hazard Ratios to be calculated before (HR 540 of follow-up. Multivariate analyses showed that fibrates were associated with an increased risk for the endpoint after 540 days: HR 540 = 1.73 (1.28-2.32.Fibrate monotherapy is commonly prescribed in diabetic patients with high cardiovascular risk and is associated with poorer outcomes compared to statin therapy.

    Despite the introduction of new drugs and innovative devices contributing in the last years to improve patients' quality of life, morbidity and mortality from cardiovascular diseases remain high. There is an urgent need for addressing the underlying problem of the loss of cardiac or vascular tissues and therefore developing new therapies. Autologous vascular transplants are often limited by poor quality of donor sites and heart organ transplantation by donor shortage. Vascular and cardiac tissue engineering, whose aim is to repair or replace cardiovascular tissues by the use of cells, engineering and materials, as well as biochemical and physicochemical factors, appears in this scenario as a promising tool to repair the damaged hearts and vessels. We will present a general overview on the fundamentals in the area of cardiac and vascular tissue engineering as well as on the latest progresses and challenges.

    The epidemic of obesity has contributed to a growing burden of metabolic syndrome (MetS) and diabetes mellitus (DM) worldwide. MetS is defined as central obesity along with associated factors such as hypertriglyceridemia, low high-density lipoprotein cholesterol, hyperglycemia, and hypertension. MetS and DM are associated with significant cardiovascular morbidity and mortality. Healthy behavioural modification is the cornerstone for reducing the atherosclerotic cardiovascular disease burden in this population. Comprehensive, multi-disciplinary cardiac rehabilitation (CR) programs reduce mortality and hospitalizations in patients with MetS and DM. Despite this benefit, patients with MetS and DM are less likely to attend and complete CR because of numerous barriers. Implementation of innovative CR delivery models might improve utilization of CR and cardiovascular outcomes in this high-risk population. PMID:27692115

    Full Text Available Thiazolidinediones (TZDs were widely used for the treatment of type 2 diabetes. Recent studies have shown that TZDs have paradoxical effects on cardiovascular diseases. The objective of the present study was to investigate the effect of TZDs (Rosiglitazone and Pioglitazone in High Fructose Diet (HFD induced hypertension in rats. HFD was given for 14 weeks. After 8 weeks of hypertension induction period, treatment phase was started with Rosiglitazone (ROSI 10 and 30 mg/kg, p.o. and Pioglitazone (PIO 10 and 30 mg/kg, p.o. to the respective groups which were continued till 6 weeks. Systolic Blood Pressure (SBP was measured weekly and serum glucose, triglyceride, cholesterol and HDL-C were measured at the end of study period. In HFD fed rats hypertension was observed after 8 weeks. Treatment with the test drugs significantly reversed the changes in serum enzyme levels as well as SBP made by HFD feeding compared to the control group. The study concludes that TZDs possess antihypertensive effect as exhibited in the present experimental settings.

    Full Text Available Background: A controversy exists regarding the association between subclinical hypothyroidism (SH and dyslipidemia. Moreover, studies on lipid ratios and atherogenic index of plasma (AIP in SH are rare, particularly in the Indian scenario. Aim: This study aimed to investigate abnormalities in conventional lipid profile, lipid ratios, and AIP in SH and attempted to correlate thyroid stimulating hormone (TSH and AIP in SH. Materials and Methods: In this retrospective analysis of patient records of SH subjects and euthyroid subjects, age, free triiodothyronine, free thyroxine, TSH, total cholesterol, triglycerides, high-density lipoprotein-cholesterol (HDL-C, low-density lipoprotein-cholesterol, lipid ratios, and AIP were compared between the two groups. The correlation of TSH and AIP in SH was studied. Spearman′s correlation, Mann-Whitney U-test and logistic regression analysis were performed. Results: Triglyceride, triglyceride/HDL-C, and AIP were significantly higher in SH as compared to euthyroid group, but there was no correlation between TSH and AIP in SH. AIP emerged as the significant single factor associated with SH in multiple logistic regressions. Conclusion: The positive association of dyslipidemia and SH indicates a need for regular screening of these patients to enable early diagnosis and treatment of dyslipidemia. Even in patients who have a normal conventional lipid profile, lipid ratios, and AIP have to be calculated for better assessment of atherogenic risk.

    Full Text Available AIMS: To investigate if diet quality is related to incidence of cardiovascular (CV events. SUBJECTS AND METHODS: A diet quality index based on the 2005 Swedish Nutrition Recommendations and the Swedish Dietary Guidelines was created and included six dietary components: saturated fatty acids, polyunsaturated fatty acids, fish and shellfish, dietary fiber, fruit and vegetables, and sucrose. The index ranked 17126 participants (59% women of the population-based Malmö Diet and Cancer cohort (Sweden on their dietary intakes. Total index score was categorized as low, medium or high. Cox proportional hazard regression was used to model associations between index score categories and index components with risk of incident CV events, with adjustment for potential confounders. The incidence of first CV events (non-fatal or fatal myocardial infarction or ischemic stroke or death from ischemic heart disease was monitored from baseline (1991-1996 until December 31, 2008; 703 CV events occurred in women and 1093 in men. RESULTS: A high diet quality was associated with decreased risk of CV events when compared to a low diet quality. In multivariate analysis, the risk reduction was 32% (hazard ratio = 0.68, 95% confidence interval: 0.49-0.73 in men and 27% (hazard ratio = 0.73, 95% confidence interval: 0.59-0.91 in women. When examined separately and mutually adjusted for each other, the individual components were either not associated with CV risk or marginally decreased risks were seen. CONCLUSION: High quality diets in line with current recommendations may reduce the risk of CV events. This study illustrates the importance of considering a combination of dietary factors when evaluating diet-disease associations.

    Numerous recent studies convincingly correlate the upper thermal tolerance limit of aquatic ectothermic animals to reduced aerobic scope, and ascribe the decline in aerobic scope to failure of the cardiovascular system at high temperatures. In the present study we investigate whether this 'aerobic scope model' applies to an air-breathing and semi-terrestrial vertebrate Rhinella marina (formerly Bufo marinus). To quantify aerobic scope, we measured resting and maximal rate of oxygen consumption at temperatures ranging from 10 to 40°C. To include potential effects of acclimation, three groups of toads were acclimated chronically at 20, 25 and 30°C, respectively. The absolute difference between resting and maximal rate of oxygen consumption increased progressively with temperature and there was no significant decrease in aerobic scope, even at temperature immediately below the lethal limit (41-42°C). Haematological and cardiorespiratory variables were measured at rest and immediately after maximal activity at benign (30°C) and critically high (40°C) temperatures. Within this temperature interval, both resting and active heart rate increased, and there was no indication of respiratory failure, judged from high arterial oxygen saturation, P(O2) and [Hb(O2)]. With the exception of elevated resting metabolic rate for cold-acclimated toads, we found few differences in the thermal responses between acclimation groups with regard to the cardiometabolic parameters. In conclusion, we found no evidence for temperature-induced cardiorespiratory failure in R. marina, indicating that maintenance of aerobic scope and oxygen transport is unrelated to the upper thermal limit of this air-breathing semi-terrestrial vertebrate.

    Epidemiologic studies have suggested that flavonoid intake plays a critical role in the prevention of coronary heart disease. Because atherosclerosis is considered a low-grade inflammatory disease, some feeding trials have analyzed the effects of cocoa (an important source of flavonoids) on inflammatory biomarkers, but the results have been controversial. The objective was to evaluate the effects of chronic cocoa consumption on cellular and serum biomarkers related to atherosclerosis in high-risk patients. Forty-two high-risk volunteers (19 men and 23 women; mean +/- SD age: 69.7 +/- 11.5 y) were included in a randomized crossover feeding trial. All subjects received 40 g cocoa powder with 500 mL skim milk/d (C+M) or only 500 mL skim milk/d (M) for 4 wk. Before and after each intervention period, cellular and serum inflammatory biomarkers related to atherosclerosis were evaluated. Adherence to the dietary protocol was excellent. No significant changes in the expression of adhesion molecules on T lymphocyte surfaces were found between the C+M and M groups. However, in monocytes, the expression of VLA-4, CD40, and CD36 was significantly lower (P = 0.005, 0.028, and 0.001, respectively) after C+M intake than after M intake. In addition, serum concentrations of the soluble endothelium-derived adhesion molecules P-selectin and intercellular adhesion molecule-1 were significantly lower (both P = 0.007) after C+M intake than after M intake. These results suggest that the intake of cocoa polyphenols may modulate inflammatory mediators in patients at high risk of cardiovascular disease. These antiinflammatory effects may contribute to the overall benefits of cocoa consumption against atherosclerosis. This trial was registered in the Current Controlled Trials at London, International Standard Randomized Controlled Trial Number, at controlled-trials.com as ISRCTN75176807.
