Risk Factor For Cardiovascular Disease Events Research Articles

Risk of cancer history in cardiovascular disease among individuals with hypertension.

Hypertension is the leading risk factor for cardiovascular disease (CVD). Although cancer has recently been increasingly recognized as a novel risk factor for CVD events, little is known about whether co-morbid cancer in individuals with hypertension could further increase the risk of CVD events. We sought to determine the association between the cancer history and the risk of CVD in individuals with hypertension. We retrospectively analyzed a large cohort of 747,620 individuals diagnosed with hypertension from January 2005 through May 2022 using the JMDC Claims Database. Composite CVD events, including myocardial infarction (MI), angina pectoris (AP), stroke, heart failure (HF), and atrial fibrillation (AF), were recorded, and a Cox proportional hazard regression was done to estimate hazard ratios (HR) based on the history of cancer and chemotherapy. 26,531 individuals had a history of cancer. During the mean follow-up period of 1269 ± 962 days, 67,154 composite CVD events were recorded. Compared with individuals without a cancer history, cancer survivors had a higher risk of developing composite CVD events (HR: 1.21, 95% confidence interval [CI]: 1.17-1.26). The HRs (95% CIs) associated with cancer history for MI, AP, stroke, HF, and AF were 1.07 (0.90-1.27), 1.13 (1.06-1.20), 1.14 (1.06-1.24), 1.31 (1.25-1.38), and 1.22 (1.10-1.35), respectively. Lastly, individuals who had received chemotherapy for cancer had a particularly higher risk of developing CVD compared to those who did not undergo chemotherapy. A history of cancer was associated with a greater risk of developing CVD among individuals with hypertension.

Effect of gender on the association between cumulative cardiovascular risk factors and depression: results from the US National Health and Nutrition Examination Survey

BackgroundThe comorbidity of cardiovascular disease (CVD) and depression has been well established, as depression usually presents simultaneously with CVD risk factors. However, the potential association between cumulative exposure to CVD...

Coronary artery calcium among patients with heterozygous familial hypercholesterolaemia.

We aimed to determine if coronary artery calcium (CAC) is associated with cardiovascular disease (CVD) events, defined as CVD-related death, unstable angina, myocardial infarction, or staged revascularization among patients with heterozygous familial hypercholesterolaemia (HeFH) under primary prevention settings. Data of patients with FH admitted to Kanazawa University Hospital between 2000 and 2020, who underwent CAC measurement and were followed up (n = 622, male = 306, mean age = 54 years), were retrospectively reviewed. Risk factors for CVD events were determined using the Cox proportional hazard model. The median follow-up duration was 13.2 years (interquartile range: 9.8-18.4 years). We observed 132 CVD events during the follow-up period. The event rate per 1000 person-years for CAC scores of 0 [n = 283 (45.5%)], 1-100 [n = 260 (41.8%)], and >100 [n = 79 (12.7%)] was 1.2, 17.0, and 78.8, respectively. Log (CAC score + 1) was a significant predictor of the occurrence of CVD events (hazard ratio: 3.24; 95% confidence interval: 1.68-4.80; P < 0.0001) in the multivariate Cox regression analysis, independent of other factors. The risk discrimination of CVD events was enhanced by adding CAC information to other conventional risk factors (C-statistics: 0.833-0.934; P < 0.0001). The CAC score helps in further risk stratification in patients with HeFH.

Prescribed opioid use is associated with adverse cardiovascular outcomes in community-dwelling older persons.

Prescribed opioids are commonly used in the older community-dwelling population for the treatment of chronic pain. Although the harmful effects of opioid abuse and overdose are well understood, little is known about the long-term cardiovascular (CV) effects of prescribed opioids. The aim of this study was to investigate the CV effects associated with prescribed opioid use. A post hoc analysis of participants in the Aspirin in Reducing Events in the Elderly (ASPREE) trial was conducted. Participants in the ASPREE trial included community-dwelling older adults without a prior history of CV disease (CVD). Prescribed opioid use was defined as opioid use at baseline and/or at the first annual visit (AV1). Cox proportional hazards regression was used to calculate hazard ratios and 95% confidence intervals (95% CI) for associations between opioid use and CVD events following AV1. Of the 17 701 participants included (mean age 75.2years, 58.2% female), 813 took opioids either at baseline or at AV1. Over a median follow-up period of 3.58years (IQR 2.50-4.62), CVD events, most notably heart failure hospitalization, occurred in 7% (n=57) amongst opioid users and 4% (n=680) amongst non-opioid users. After adjustment for multiple covariates, opiate use was associated with a 1.67-fold (CI 1.26-2.23, P<0.001) increase in the hazard ratio for CVD events. These findings identify opioid use as a non-traditional risk factor for CVD events in community-dwelling older adults.

Abstract #1177327: Liver Fat and Cardiovascular Events: bystander or causative relationship?

Non-alcoholic fatty liver disease (NAFLD) and cardiovascular disease (CVD) share common metabolic risk factors, and there is a high prevalence of CVD in patients with NAFLD. We aimed to determine if liver fat is an independent risk factor for CVD events.

Assessment of CVD Risk Factors in Secondary Prevention after Ischemic Stroke Using the ICF.

Background: Patients after undergoing ischemic stroke have a high risk of further cardiovascular disease (CVD) incidents. Monitoring risk factors is critical to prevent the recurrence of CVD. Objective: The aim of the study was to determine differences in the incidence of risk factors for CVD in a post-ischemic stroke patient group (SG) compared to the control group, which had not undergone ischemic stroke (CG), and to characterize them using the ICF (International Classification of Functioning, Disability and Health) classification system. Materials and Methods: The incidence of risk factors for recurrent CVD events were retrospectively analyzed in 55 patients in SG and 55 patients in CG. The results were translated into categories from the ICF classification system. Results: Atrial fibrillation (p = 0.013), carotid artery stenosis > 50% (p < 0.001), LDL > 71 mg/dL (p < 0.001), heart rate > 80/min (p = 0.007), taking NOAC (p = 0.008) and NSAIDs (p < 0.001) as well as nicotinism (p = 0.001) were significantly more common in SG compared to CG. The value of the distribution of the total incidence of CVD risk factors were observed to be higher for SG than for CG. In SG, both for males (p < 0.001) and females (p < 0.001) more risk factors for recurrent CVD incidents were observed compared to CG. Conclusions: Patients in SG differ in the occurrence of risk factors for CVD event compared to CG. The use of a single tool, such as the ICF assessment sheet, can be useful in assessing and analyzing risk factors for recurrent CVD events. This may help to reduce the risk of subsequent CVD events in secondary prevention.

Cardiovascular disease risk factors induce mesenchymal features and senescence in mouse cardiac endothelial cells.

Aging, obesity, hypertension, and physical inactivity are major risk factors for endothelial dysfunction and cardiovascular disease (CVD). We applied fluorescence-activated cell sorting (FACS), RNA sequencing, and bioinformatic methods to investigate the common effects of CVD risk factors in mouse cardiac endothelial cells (ECs). Aging, obesity, and pressure overload all upregulated pathways related to TGF-β signaling and mesenchymal gene expression, inflammation, vascular permeability, oxidative stress, collagen synthesis, and cellular senescence, whereas exercise training attenuated most of the same pathways. We identified collagen chaperone Serpinh1 (also called as Hsp47) to be significantly increased by aging and obesity and repressed by exercise training. Mechanistic studies demonstrated that increased SERPINH1 in human ECs induced mesenchymal properties, while its silencing inhibited collagen deposition. Our data demonstrate that CVD risk factors significantly remodel the transcriptomic landscape of cardiac ECs inducing inflammatory, senescence, and mesenchymal features. SERPINH1 was identified as a potential therapeutic target in ECs.

Long-Term Blood Pressure Variability and Risk of Cardiovascular Disease Events Among Community-Dwelling Elderly.

High office blood pressure variability (OBPV) in midlife increases the risk of cardiovascular disease (CVD), but the impact of OBPV in older adults without previous CVD is unknown. We conducted a post hoc analysis of ASPREE trial (Aspirin in Reducing Events in the Elderly) participants aged 70-years and older (65 for US minorities) without history of CVD events at baseline, to examine risk of incident CVD associated with long-term, visit-to-visit OBPV. CVD was a prespecified, adjudicated secondary end point in ASPREE. We estimated OBPV using within-individual SD of mean systolic BP from baseline and first 2 annual visits. Cox proportional hazards regression was used to calculate hazard ratios (HR) and 95% CI for associations with CVD events. In 16 475 participants who survived to year 2 without events, those in the highest tertile of OBPV had increased risk of CVD events after adjustment for multiple covariates, when compared with participants in the lowest tertile (HR, 1.36 [95% CI, 1.08-1.70]; P=0.01). Similar increased risk was observed for ischemic stroke (HR, 1.56 [95% CI, 1.04-2.33]; P=0.03), heart failure hospitalization, or death (HR, 1.73 [95% CI, 1.07-2.79]; P=0.02), and all-cause mortality (HR, 1.27 [95% CI, 1.04-1.54]; P=0.02). Findings were consistent when stratifying participants by use of antihypertensive drugs, while sensitivity analyses suggested the increased risk was especially for individuals whose BP was uncontrolled during the OBPV estimation period. Our findings support increased OBPV as a risk factor for CVD events in healthy older adults with, or without hypertension, who have not had such events previously.

A prospective study on the influence of metabolic syndrome on the risks of cardiovascular disease events and all-cause mortality for urban residents aged 40-79 years in Guiyang

Objective To explore the influence of metabolic syndrome on the risks of cardiovascular disease (CVD) events and all-cause mortality. Methods In this prospective cohort study, urban residents aged 40-79 years in Guiyang were followed-up for three years. The end-points were CVD events and all-cause mortality. COX proportional hazards model were used for the corresponding hazard ratios (HRs) of CVD events and all-cause mortality. Metabolic syndrome was defined according to the 2005 International Diabetes Federation (IDF) criteria. Results A total of 7 313 subjects were included. 146 cases of CVD events and 80 cases of all-cause mortality were recorded. After adjusting for gender, age, smoking, alcohol consumption, and blood lipid levels, the metabolic syndrome increased the risks of CVD events and all-cause mortality. The HRs were 1.43 (P=0.037) and 1.25 (P=0.418), respectively. As compared metabolic syndrome with non-metabolic syndrome, an increased risk of CVD events was found. The HR was 1.43 (P=0.013). No significantly increased risk of all-cause mortality was found in subjects with metabolic syndrome. Conclusion The metabolic syndrome was associated with increased risk of CVD events and there was no significant increase in all-cause mortality. Metabolic syndrome is an important risk factor for CVD events. Key words: Metabolic syndrome; Cardiovascular disease events; All-cause mortality; Cohort study

The Impact of Treatment Adherence for Patients With Diabetes and Hypertension on Cardiovascular Disease Risk: Protocol for a Retrospective Cohort Study, 2008-2018.

BackgroundCardiovascular disease (CVD) is the leading cause of death globally and in Canada. Diabetes and hypertension are major risk factors for CVD events. Despite the increasing availability of effective treatments, the majority of diabetic and hypertensive patients do not have adequate blood pressure and glycemic control. One of the major contributors is poor treatment adherence.ObjectiveThis study aims to evaluate the impact of treatment adherence for patients with both diabetes and hypertension on acute severe CVD events and intermediate clinical outcomes in Canadian primary care settings.MethodsWe will conduct a population-based retrospective cohort study of patients living with both diabetes and hypertension in Ontario, Canada, between January 1, 2008, and March 31, 2018. The Social Cognitive Theory will be used as a conceptual framework by which to frame the reciprocal relationship between treatment adherence, personal factors, and environmental determinants and how this interplay impacts CVD events and clinical outcomes. Data will be derived from the Diabetes Action Canada National Data Repository. A time-varying Cox proportional hazards model will be used to estimate the impacts of treatment adherence on CVD morbidity and mortality. Multivariable linear regression models and hierarchical regression models will be used to estimate the associations between treatment adherence of different medication categories and intermediate clinical outcomes. Our primary outcome is the association between treatment adherence and the risk of acute severe CVD events, including CVD mortality. The secondary outcome is the association between treatment adherence and intermediate clinical outcomes including diastolic and systolic blood pressures, glycated hemoglobin, low-density lipoprotein cholesterol, and total cholesterol. Owing to data limitation, we use medication prescriptions as a proxy to estimate treatment adherence. We assume that a patient adhered to medications if she or he had any prescription record in the 4 preceding quarters and 1 quarter after each quarter of interest. Acute severe CVD events are defined based on the World Health Organization’s Monitoring Trends and Determinants in Cardiovascular Disease Project, including acute coronary heart disease, stroke, and heart failure. As causes of death are not available, the number of CVD deaths will be computed using the most recent systolic blood pressure distributions and the population attributable risks related to systolic blood pressure level.ResultsThe project was funded by Diabetes Action Canada (reference number: 503854) and approved by the University of Toronto Research Ethics Board (reference number: 36065). The project started in June 2018 and is expected to be finished by September 2019.ConclusionsThe findings will be helpful in identifying the challenges of treatment adherence for diabetic and hypertensive patients in primary care settings. This will also help to develop intervention strategies to promote treatment adherence for patients with multi-morbidities.International Registered Report Identifier (IRRID)DERR1-10.2196/13571

Direct Automatic Coronary Calcium Scoring in Cardiac and Chest CT.

Cardiovascular disease (CVD) is the global leading cause of death. A strong risk factor for CVD events is the amount of coronary artery calcium (CAC). To meet the demands of the increasing interest in quantification of CAC, i.e., coronary calcium scoring, especially as an unrequested finding for screening and research, automatic methods have been proposed. The current automatic calcium scoring methods are relatively computationally expensive and only provide scores for one type of CT. To address this, we propose a computationally efficient method that employs two convolutional neural networks: the first performs registration to align the fields of view of input CTs and the second performs direct regression of the calcium score, thereby circumventing time-consuming intermediate CAC segmentation. Optional decision feedback provides insight into the regions that are contributed to the calcium score. Experiments were performed using 903 cardiac CT and 1687 chest CT scans. The method predicted calcium scores in less than 0.3 s. The intra-class correlation coefficient between predicted and manual calcium scores was 0.98 for both cardiac and chest CT. The method showed almost perfect agreement between automatic and manual CVD risk categorization in both the datasets, with a linearly weighted Cohen's kappa of 0.95 in cardiac CT and 0.93 in chest CT. Performance is similar to that of the state-of-the-art methods, but the proposed method is hundreds of times faster. By providing visual feedback, insight is given in the decision process, making it readily implementable in clinical and research settings.

930. HCV Treatment Is Associated With a Reduced Risk of Cardiovascular Disease Events: Results From ERCHIVES

BackgroundStudies reporting on the association between HCV and cardiovascular disease (CVD), and effect of HCV treatment upon future risk of CVD have shown mixed results.MethodsWithin ERCHIVES (Electronically Retrieved Cohort of HCV Infected Veterans), we identified all persons treated for ≥7 weeks and propensity-score-matched group who never received HCV treatment. We excluded those with HIV, HBV, or previously diagnosed CVD. Incidence rate (per 1,000 person-years) and risk factors for CVD events (Cox proportional hazards analysis) were determined for various treatment groups. CVD events were identified using ICD-9CM/ICD-10 codes. Kaplan–Meier plots were generated to show and compare CVD-free survival by treatment status and attainment of SVR.ResultsAmong 32,575 treated and same number of untreated persons in the final dataset, median age was 58 years, 27% were Black race, and 96% were male. The incidence rate for CVD events/1,000 person-years (95% CI) among the treated was 19.10 (17.79, 20.50) vs. 32.37 (30.51, 34.33) among the untreated (P < 0.01). Treatment with a DAA regimen (vs. PEG/RBV; HR [95% CI] 0.68 [0.53,0.88]) and achieving SVR (HR [95% CI] 0.76 [0.63,0.92]) were associated with a lower risk of incidence CVD event (table). Kaplan–Meier curves demonstrated that untreated persons had a shorter CVD event-free survival during 30 months of follow-up compared with the treated persons. (figure; log-rank P < 0.0001)ConclusionHCV treatment is associated with a reduction in incident CVD events. Directly acting antiviral regimens (vs. PEG/RBV) and attainment of SVR (vs. no SVR) are associated with a lower risk of incident CVD events. Disclosures A.

Circulating oleic acid levels are related to greater risks of cardiovascular events and all-cause mortality: The Multi-Ethnic Study of Atherosclerosis

Limited evidence has suggested that circulating levels of the omega-9 fatty acid, oleic acid, may be related to greater risks of adverse cardiovascular outcomes. We aimed to determine whether plasma oleic acid may be independently associated with clinical and subclinical cardiovascular disease (CVD) and all-cause mortality in a large multiethnic cohort. Plasma fatty acids were measured by gas chromatography-flame ionization in 6568 participants of the Multi-Ethnic Study of Atherosclerosis. The presence of coronary artery calcium (CAC) and aortic valve calcification (AVC) was determined by computed tomography, and carotid plaque was assessed by ultrasound. Incident CVD was defined as myocardial infarction, fatal coronary heart disease, resuscitated cardiac arrest, stroke, or stroke death. Heart failure (HF) was adjudicated from clinical records. Relative risk regression estimated plasma oleic acid-related rate ratios for prevalent CAC, AVC, and carotid plaque. Cox regression estimated hazard ratios (HRs) for CVD, HF, and all-cause mortality over a median 13-year follow-up. Individuals in top quartiles of oleic acid showed greater rate ratios of CAC, AVC, and carotid plaque (all P<.001), but associations were rendered nonsignificant after adjustment for other risk factors. By contrast, those in top quartiles of plasma oleic acid showed significantly greater risks of incident HF (HR: 2.03; P<.001), CVD (HR: 1.41; P=.008), and all-cause mortality (HR: 1.55; P<.001) than those in referent quartiles independent of typical risk factors as well as plasma omega-3 fatty acid levels. Plasma oleic acid appears to be a risk factor for CVD events and all-cause mortality independent of typical risk factors and plasma omega-3 fatty acids. Additional studies are warranted for confirmation and to further examine whether plasma oleic acid directly contributes to, or serves as a marker of, disease pathogenesis. These findings should not be extrapolated to dietary oleic acid intake.

Asleep blood pressure: significant prognostic marker of vascular risk and therapeutic target for prevention.

Sleep-time blood pressure (BP) is a stronger risk factor for cardiovascular disease (CVD) events than awake and 24 h BP means, but the potential role of asleep BP as therapeutic target for diminishing CVD risk is uncertain. We investigated whether CVD risk reduction is most associated with progressive decrease of either office or ambulatory awake or asleep BP mean. We prospectively evaluated 18078 individuals with baseline ambulatory BP ranging from normotension to hypertension. At inclusion and at scheduled visits (mainly annually) during follow-up, ambulatory BP was measured for 48 consecutive hours. During the 5.1-year median follow-up, 2311 individuals had events, including 1209 experiencing the primary outcome (composite of CVD death, myocardial infarction, coronary revascularization, heart failure, and stroke). The asleep systolic blood pressure (SBP) mean was the most significant BP-derived risk factor for the primary outcome [hazard ratio 1.29 (95% CI) 1.22-1.35 per SD elevation, P < 0.001], regardless of office [1.03 (0.97-1.09), P = 0.32], and awake SBP [1.02 (0.94-1.10), P = 0.68]. Most important, the progressive attenuation of asleep SBP was the most significant marker of event-free survival [0.75 (95% CI 0.69-0.82) per SD decrease, P < 0.001], regardless of changes in office [1.07 (0.97-1.17), P = 0.18], or awake SBP mean [0.96 (0.85-1.08), P = 0.47] during follow-up. Asleep SBP is the most significant BP-derived risk factor for CVD events. Furthermore, treatment-induced decrease of asleep, but not awake SBP, a novel hypertension therapeutic target requiring periodic patient evaluation by ambulatory monitoring, is associated with significantly lower risk for CVD morbidity and mortality.

Stroke and (or) myocardial infarction attributable to modifiable risk factors in Henan, China

Estimating population attributable risks of potential modifiable risk factors for stroke and (or) myocardial infarction may be useful for planning cardiovascular disease (CVD) preventive strategies. A population of 17,292 adults aged 18 years and older from a cross-sectional survey was included in the study. The binary logistic regression was used to evaluate the association between risk factors with disease events, then population attributable fraction according to prevalence and odds ratios were calculated to identify and compare the effects at different subpopulations. We found that the main risk factor for CVD events was hypertension with about 50% of population attributable fraction; prehypertension (22.24%) only acts at rural older females; the efficiency of low- and moderate-level physical activities were higher in males (over 20%) than females (under 20%); ever smoked contributed to CVDs in rural older populations (males, 19.25%; females, 5.57%) and urban younger males (54.52%); while as for high body mass index, overweight (12.59%) only made contribution to rural males over 60 years. In conclusion, hypertension control in the whole population, physical activity increasing in males and older females, smoking prevention in rural elders and urban younger males, and slimming in rural elder males might be effective to reduce the burden of CVDs in Henan.

Abstract P006: Cardiovascular Disease Risk Factor Burden is Associated With Hearing Loss in Young Men: The Hispanic Community Health Study/Study of Latinos

Introduction: Over 30 million Americans suffer from hearing loss (HL). Studies suggest that established cardiovascular disease (CVD) risk factors may contribute to the pathophysiology of the inner ear. However, the aggregate effect of CVD risk factors on hearing is not well understood. Hypothesis: We hypothesized that high CVD risk burden is associated with worse hearing. Methods: We assessed younger (ages 18-34) and older (ages 55-64) Hispanic Community Health Study / Study of Latinos participants who underwent audiometry in 2008-11. After excluding those with conductive pathology and asymmetric HL, we randomly chose one ear for analysis. Puretone thresholds were obtained at 0.5-8 kHz; puretone average (PTA) was calculated using thresholds at 0.5, 1, 2, and 4 kHz. Low CVD risk burden was defined as having all of: blood pressure (BP) &lt;120/&lt;80 mmHg; total cholesterol &lt;180 mg/dL; not currently smoking; and not having prevalent diabetes. High CVD risk burden was defined as ≥ 2 of: diabetes; currently smoking; BP &gt;160/&gt;100 mmHg (or antihypertensive use); and total cholesterol &gt;240 mg/dL (or statin use). By age group and sex, we estimated hearing thresholds per frequency with linear regression models adjusted for noise exposure. Least squares estimates were calculated using strata-specific means of covariates. Estimates were compared via t-tests. Data were weighted for all analyses and accounted for clustering. Results: Among younger and older individuals in the target population (51.9% female), 28.8% had low and 5.5% had high CVD risk. Younger men with high CVD risk had worse PTA than young men with low risk (7.7 dB HL [7.0-8.4] vs. 10.5 dB HL [8.4-12.5], p =0.02), and had significantly worse thresholds at 1,3,4,6 kHz than those with low risk ( Figure ). There was no difference in PTA or thresholds at any frequency by CVD risk burden in young women, older men, or older women. Conclusions: CVD risk burden is associated with HL among young men, but not young women or older adults. CVD risk burden may be useful for identifying young men at risk for HL.

Risk Factors for Prognosis in Patients With Severely Decreased GFR

IntroductionPatients with chronic kidney disease (CKD) and estimated glomerular filtration rate (eGFR) <30 ml/min per 1.73 m2 (corresponding to CKD stage G4+) comprise a minority of the overall CKD population but have the highest risk for adverse outcomes. Many CKD G4+ patients are older with multiple comorbidities, which may distort associations between risk factors and clinical outcomes.MethodsWe undertook a meta-analysis of risk factors for kidney failure treated with kidney replacement therapy (KRT), cardiovascular disease (CVD) events, and death in participants with CKD G4+ from 28 cohorts (n = 185,024) across the world who were part of the CKD Prognosis Consortium.ResultsIn the fully adjusted meta-analysis, risk factors associated with KRT were time-varying CVD, male sex, black race, diabetes, lower eGFR, and higher albuminuria and systolic blood pressure. Age was associated with a lower risk of KRT (adjusted hazard ratio: 0.74; 95% confidence interval: 0.69–0.80) overall, and also in the subgroup of individuals younger than 65 years. The risk factors for CVD events included male sex, history of CVD, diabetes, lower eGFR, higher albuminuria, and the onset of KRT. Systolic blood pressure showed a U-shaped association with CVD events. Risk factors for mortality were similar to those for CVD events but also included smoking. Most risk factors had qualitatively consistent associations across cohorts.ConclusionTraditional CVD risk factors are of prognostic value in individuals with an eGFR <30 ml/min per 1.73 m2, although the risk estimates vary for kidney and CVD outcomes. These results should encourage interventional studies on correcting risk factors in this high-risk population.

Elevated High Sensitivity C‐Reactive Protein Increases the Risk of Microalbuminuria in Subjects With Cardiovascular Disease Risk Factors

Microalbuminuria is an early biomarker of kidney injury, the aim of this study was to investigate the impact of high sensitivity C-reactive protein (hs-CRP) on microalbuminuria in adults with cardiovascular disease (CVD) risk factors. A total of 5667 subjects who voluntarily attended annual health screenings in the Third Xiangya Hospital of Central South University were included in the study. Logistic regression was used to determine the validity of hs-CRP to predict the presence of microalbuminuria. In the unadjusted regression analysis, male gender (OR 2.23), age (OR 1.71), smoking status (OR 1.48), obesity (OR 2.41), hypertension(OR 4.03), diabetes (OR 4.61), hyperuricemia (OR 1.83), and high hs-CRP(OR 1.61) were associated with microalbuminuria. Multivariate logistic regression analysis showed that the adjusted odds ratios (OR) of diabetes, hypertension, male, abdominal obesity, and high hs-CRP for microalbuminuria were 2.71, 2.57, 1.51, 1.28 and 1.41 in all subjects, respectively (P<0.01). ROC analysis indicated that the cut-off for hs-CRP with better properties for screening of microalbuminuria was identified as ≥0.85mg/L. The ORs of microalbuminuria were 1.97, 1.49, 1.32 and 1.71 times in male, abdominal obesity, diabetes and hypertension subjects with hs-CRP≥0.85mg/L, respectively, compared with those without elevated hs-CRP (P<0.01). Elevated hs-CRP level was associated with microalbuminuria independent of cardiovascular risk factors. In addition, elevated hs-CRP increased the risk of developing microalbuminuria in subjects with CVD risk factors, indicating that chronic inflammation could amplify the deterioration of kidney by effect of CVD risk factors.

Older adult awareness of the influence of cardiovascular disease risk factors on cognitive function.

The aims of the current study were to (i) assess older people's awareness of the association between CVD risk factors and cognitive function; and (ii) examine whether awareness varies as a function of demographic factors. Cardiovascular disease (CVD) risk factors have been linked to subtle deficits in cognitive function. CVD risk factors increase the risk of cognitive decline and dementia. The association between cardiovascular disease (CVD) risk factors and cognitive decrements has been well documented among older people; however, we are unaware of any studies that have measured older people's awareness of this relationship in an effort to assess educational needs. A descriptive, cross-sectional survey design was employed. Community-based older adults aged 60 and older completed a survey that assessed their knowledge of the association between CVD risk factors and cognitive function. One hundred fifty older adults, with a mean age of 72.88years, completed the survey. Results showed that over 75% of the sample was aware that CVD risk factors affect cognitive function. White older adults and older adults with greater perceived financial well-being tended to be more aware of these relationships than non-White participants with less perceived financial well-being. Results suggest that many, but not all older people have awareness of this relationship. As such, there is a need for increased education about the cognitive effects of CVD risk factors, particularly among older people who are already at risk for developing CVD and those with lesser financial well-being. Appropriate educational strategies can expose older patients to the importance of healthy lifestyle and self-care to maintain cognitive function. Nurses can incorporate education into care by identifying patients that would benefit from tailored interventions and providing information to at-risk patients about how to maintain their cognitive function through management of specific CVD risk factors.

Worldwide Exposures to Cardiovascular Risk Factors and Associated Health Effects: Current Knowledge and Data Gaps.

Information on exposure to, and health effects of, cardiovascular disease (CVD) risk factors is needed to develop effective strategies to prevent CVD events and deaths. Here, we provide an overview of the data and evidence on worldwide exposures to CVD risk factors and the associated health effects. Global comparative risk assessment studies have estimated that hundreds of thousands or millions of CVD deaths are attributable to established CVD risk factors (high blood pressure and serum cholesterol, smoking, and high blood glucose), high body mass index, harmful alcohol use, some dietary and environmental exposures, and physical inactivity. The established risk factors plus body mass index are collectively responsible for ≈9.7 million annual CVD deaths, with high blood pressure accounting for more CVD deaths than any other risk factor. Age-standardized CVD death rates attributable to established risk factors plus high body mass index are lowest in high-income countries, followed by Latin America and the Caribbean; they are highest in the region of central and eastern Europe and central Asia. However, estimates of the health effects of CVD risk factors are highly uncertain because there are insufficient population-based data on exposure to most CVD risk factors and because the magnitudes of their effects on CVDs in observational studies are likely to be biased. We identify directions for research and surveillance to better estimate the effects of CVD risk factors and policy options for reducing CVD burden by modifying preventable risk factors.
