RESUMO

PURPOSE OF REVIEW: To examine the concept of time in target range for blood pressure (BP) management, exploring its calculation methods, implications for patient outcomes, and potential use in patient care. RECENT FINDINGS: Recent post-hoc analyses of clinical trials and observational studies highlight the importance of BP time in target range in predicting cardiovascular outcomes. Higher time in target range correlates with reduced risks of major adverse cardiovascular events including heart failure, stroke, myocardial infarction and all-cause mortality. Additionally, longer time in target range decreases the risk of incident atrial fibrillation and risk of developing dementia. BP time in target range is a novel metric offering valuable insights into BP control and its impact on clinical outcomes. Higher time in target range is consistently associated with better cardiovascular outcomes across various patient populations. However, the clinical application of BP time in target range requires further investigation through prospective clinical trials and real-world studies. Integrating wearable devices for continuous BP monitoring could enhance the practical utility of BP time in target range in hypertension management.

RESUMO

Aims: Utilizing serial intravascular ultrasonography (IVUS), we aimed to exam the association of intra-individual lipid variability, coronary atheroma progression, and clinical outcomes. Methods and results: We performed a post hoc patient-level analysis of nine clinical trials involving 4976 patients with coronary artery disease who underwent serial coronary IVUS in the setting of a range of medical therapies. We assessed the associations between progression in percent atheroma volume (ΔPAV), clinical outcomes, and visit-to-visit lipid variability including low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), non-HDL-C, total cholesterol (TC)/HDL-C, and apolipoprotein B (ApoB). Variability of lipid parameters was measured using intra-individual standard deviation over 3, 6, 12, 18, and 24 months. Atherogenic lipoprotein variability significantly associated with ΔPAV [odds ratio (95% confidence interval; P-value), LDL-C: 1.09 (1.02, 1.17, P = 0.01); non-HDL-C: 1.10 (1.02, 1.18, P = 0.01); TC/HDL-C: 1.14 (1.06, 1.24, P = 0.001); ApoB: 1.13 (1.03, 1.24, P = 0.01)]. Survival curves revealed significant stepwise relationships between cumulative major adverse cardiovascular events and increasing quartiles of atherogenic lipoprotein variability at 24-months follow-up (log-rank P < 0.01 for all lipoproteins except HDL-C). Stronger associations were noted between achieved lipoprotein levels and ΔPAV [LDL-C: 1.27 (1.17, 1.39; P < 0.001); non-HDL-C: 1.32 (1.21, 1.45; P < 0.001); TC/HDL-C: 1.31 (1.19, 1.45; P < 0.001); ApoB: 1.20 (1.07, 1.35; P = 0.003)]. Conclusion: Greater visit-to-visit variability in atherogenic lipoprotein levels significantly associates with coronary atheroma progression and clinical outcomes, although the association between achieved atherogenic lipoproteins and atheroma progression appears stronger. These data highlight the importance of achieving low and consistent atherogenic lipoprotein levels to promote plaque regression and improve clinical outcomes.

RESUMO

This paper evaluates the effectiveness of community health workers/promotores (CHWs) in promoting cancer preventive behaviors in the 2011-2013 Education to Promote Improved Cancer Outcomes (ÉPICO) project. The ÉPICO project utilized CHWs to disseminate cancer education to predominately Spanish-speaking Hispanics living in colonias in the Lower Rio Grande Valley of Texas. The CHWs received training to become Texas-certified CHW instructors and specialized training in message tailoring, and they delivered more than 5000 units of resident education on cancer prevention/detection, treatment, and survivorship for breast, cervical, and colorectal cancer. Using panel data to examine overtime changes in cancer knowledge among Lower Rio Grande Valley residents, the evaluation found significant changes from baseline to both times 1 and 2. Additional individual-level analysis indicated that the increase in resident cancer knowledge was predicted by residents' perceptions of CHW credibility and intention to change their lifestyles. Multilevel analysis also showed that the increase in cancer prevention knowledge among residents was predicted by attributes of the CHWs who taught them. In particular, CHWs with higher education levels had the most impact on residents' increased knowledge over time. Unexpectedly, CHWs with more years of experience were less effective teachers than their early-career counterparts.

RESUMO

OBJECTIVE: Lowering low-density lipoprotein cholesterol (LDL-C) with statins has been demonstrated to slow plaque progression. This antiatherosclerotic effect in patients with minimal LDL-C lowering has not been investigated. APPROACH AND RESULTS: Six hundred forty-seven patients with angiographic coronary artery disease who were commenced on statin therapy underwent serial imaging with intravascular ultrasound. Responders were defined as a percentage reduction in LDL-C of <15%. Disease progression was compared in responders (n=517) and hyporesponders (n=130) to statin therapy. Twenty percentage of patients demonstrated minimal changes in LDL-C, despite commencement of statin therapy. Statin hyporesponders were younger (55 versus 57 years; P=0.01), more likely to be male (79% versus 66%; P=0.005), and obese (body mass index, 31.5 ± 6.1 versus 30.3 ± 5.9 kg/m(2); P=0.04) and less likely to have a history of dyslipidemia (50% versus 66%; P<0.001). Baseline levels of systolic blood pressure (127 ± 15 versus 132 ± 17 mm Hg; P=0.01) and LDL-C (2.5 ± 0.6 versus 3.4 ± 0.8 mmol/L; P<0.001) were lower in statin hyporesponders. Baseline percent atheroma volume was similar between statin hyporesponders and responders (36.9 ± 9.8% versus 38.3 ± 9.2%; P=0.13). On serial evaluation, greater progression of percent atheroma volume (1.19 ± 0.48% versus 0.09 ± 0.43%; P=0.003) was observed in statin hyporesponders. After adjusting for baseline clinical characteristics and measures of plaque burden, statin hyporesponders still exhibited greater atheroma progression (+0.83 ± 0.58% versus -0.21 ± 0.52%; P=0.006). CONCLUSIONS: A substantial proportion of patients with coronary artery disease fail to achieve effective reductions in LDL-C, despite prescription of statin therapy. Greater progression of atherosclerosis is observed in these patients. Our current study underscores monitoring LDL-C level after the commencement of statin to ensure adequate response to statin therapy.

RESUMO

AIMS: Statins can inhibit the progression of coronary atherosclerosis. We aimed to characterize clinical factors that associate with differing measures of coronary atheroma volume following potent statin therapy. METHODS AND RESULTS: SATURN employed serial intravascular ultrasound (IVUS) to monitor changes in measures of coronary atheroma burden [total atheroma volume (TAV) and per cent atheroma volume (PAV)] in 1039 patients with coronary artery disease, treated with rosuvastatin (40 mg) or atorvastatin (80 mg) daily for 24 months. Rosuvastatin-treated patients demonstrated greater reductions in low-density lipoprotein cholesterol (LDL-C, 47 vs. 40%, P < 0.001) and greater increases in high-density lipoprotein cholesterol (HDL-C, 13 vs. 10%, P = 0.02). These alterations in the lipid profile associated with greater TAV (-6.4 vs. -4.4 mm(3), P = 0.01), but not PAV (-1.22 vs. -0.99%, P = 0.17) regression. Greater TAV reductions with rosuvastatin vs. atorvastatin occurred in patients with diabetes (P = 0.01, treatment by diabetic status interaction P-value 0.05). Greater PAV reductions with rosuvastatin were evident in females (P = 0.01, treatment by sex interaction P-value 0.03) and in those with greater than or equal to median baseline LDL-C (P = 0.02, treatment by LDL-C group interaction P-value 0.03) or HDL-C levels (P = 0.02, treatment by HDL-C group interaction P-value 0.04). On multivariable analysis assessing change in TAV and PAV, both higher baseline TAV and PAV independently associated with TAV and PAV regression, respectively (standardized estimates: TAV -0.25, P < 0.001; PAV -0.23, P < 0.001). CONCLUSION: Higher-risk patients, particularly those with greater baseline coronary atheroma volume, are more likely to experience less disease progression with potent statin therapy.

RESUMO

Background: Prior evidence demonstrates that pulse pressure (PP), a surrogate marker of arterial stiffness, is an independent risk factor for mortality and major adverse cardiovascular (CV) events. Objectives: The study aimed to identify the association of PP with death, myocardial infarction, and stroke among participants enrolled in large CV outcome clinical trials and determine if this association was impacted by pre-existing CV disease, or specific CV risk factors. Methods: A total of 65,382 individuals, ages 19 to 98 years, that were enrolled in one of five CV outcome trials were analyzed. Baseline demographics, history, blood pressures, and medications were collected. Univariate and multivariable analyses were conducted to explore temporal patterns, risks, and adjusted survival rates. Results: Mean baseline PP was 52 ± 12 mmHg. For every 10 mmHg increase in PP, there was an increased risk of death, stroke, or myocardial infarction (hazard ratio (HR) 1.11, 95 % CI 1.08 to 1.14, p < 0.001). Similarly, a PP ≥ 60 mmHg demonstrated an HR of 1.27 (95 % CI 1.19 to 1.36, p < 0.001) compared with PP < 60 mmHg. A similar association existed for all subgroups analyzed except for participants with a history of stroke where increasing PP did not increase risk (HR 1.02, 95 % CI 0.95 to 1.10, p = 0.53). PP was a better predictor of adverse outcomes when compared to both systolic and diastolic blood pressures using the AIC and C-index. Conclusions: Among participants enrolled in CV outcome trials, baseline PP is associated with increased risk of death, myocardial infarction, and stroke for those with pre-existing CV disease and risk factors with the exception of a prior history of stroke.

RESUMO

Promotoras are trusted members of underserved, at-risk Hispanic communities experiencing social and health inequities. As promotora-researchers, promotoras have the unique ability and opportunity not only to provide outreach and education but also to be actively engaged in conducting research in their communities and serve as a cultural bridge between the community and researchers. In this article, we present a case study of personal and collective empowerment of six promotora-researchers who participated in seven community-based participatory research projects. Data sources included debriefing interviews with the promotora-researchers, milestone tracking and documentation completed during and after each study, and observations by the principal investigator and project managers regarding the role of the promotora-researchers in these studies. We qualitatively analyzed the data to identify the processes and decisions that were developed and implemented in a series of projects, which resulted in promotora-researcher empowerment. We found that active engagement empowered promotora-researchers personally and collectively in all phases of the research study. Common elements that contributed to the empowerment of promotora-researchers were valuing promotora-researchers' input, enabling promotora-researchers to acquire and utilize new skills, and allowing promotora-researchers to serve as both researchers and traditional promotoras. Together, these elements enabled them to more fully participate in research projects, while allowing them to identify and address needs within their own communities.

RESUMO

UNLABELLED: BSTRACT: INTRODUCTION: Mexican-origin women in the U.S. living in colonias (new-destination Mexican-immigrant communities) along the Texas-Mexico border suffer from a high incidence of food insecurity and diet-related chronic disease. Understanding environmental factors that influence food-related behaviors among this population will be important to improving the well-being of colonia households. This article focuses on cultural repertoires that enable food choice and the everyday uses of technology in food-related practice by Mexican-immigrant women in colonia households under conditions of material hardship. Findings are presented within a conceptual framework informed by concepts drawn from sociological accounts of technology, food choice, culture, and material hardship. METHODS: Field notes were provided by teams of promotora-researchers (indigenous community health workers) and public-health professionals trained as participant observers. They conducted observations on three separate occasions (two half-days during the week and one weekend day) within eight family residences located in colonias near the towns of Alton and San Carlos, Texas. English observations were coded inductively and early observations stressed the importance of technology and material hardship in food-related behavior. These observations were further explored and coded using the qualitative data package Atlas.ti. RESULTS: Technology included kitchen implements used in standard and adapted configurations and household infrastructure. Residents employed tools across a range of food-related activities identified as forms of food acquisition, storage, preparation, serving, feeding and eating, cleaning, and waste processing. Material hardships included the quality, quantity, acceptability, and uncertainty dimensions of food insecurity, and insufficient consumption of housing, clothing and medical care. Cultural repertoires for coping with material hardship included reliance on inexpensive staple foods and dishes, and conventional and innovative technological practices. These repertoires expressed the creative agency of women colonia residents. Food-related practices were constrained by climate, animal and insect pests, women's gender roles, limitations in neighborhood and household infrastructure, and economic and material resources. CONCLUSIONS: This research points to the importance of socioeconomic and structural factors such as gender roles, economic poverty and material hardship as constraints on food choice and food-related behavior. In turn, it emphasizes the innovative practices employed by women residents of colonias to prepare meals under these constraints.

RESUMO

Introduction: Approximately half of adult Americans suffer from musculoskeletal disorders (MSD). Significant risk factors for musculoskeletal disorders include poor diet, obesity, and insufficient physical activity. Studies show that lifestyle change education and interventions reduce MSD risk factors. However, little is known about the relationship between physician advice for behavior change and reported behavior change by MSD patients. This study explored the association between physician advice for lifestyle change and reported change in MSD patients, as well as the effects that patient education levels have on compliance. Methods: This study used data from the 2017 National Health Interview Survey, a nationally representative cross-sectional survey of non-institutionalized US adults. The research team limited analysis to adults who reported a limitation due to musculoskeletal problems (n = 2,672). Outcomes included physician recommendations to increase physical activity, reduce fat/calories, or lose weight, and whether they enacted these behavioral changes. Adjusted logistic regression models examined whether compliance with doctor's instructions differed by education level. Results: Adjusted models show patients advised to change physical activity, diet, and weight were more likely to report attempted behavior change. Education was positively associated with likelihood of complying with physician advice to increase physical activity. Among patients not advised to change behaviors by a physician, education was positively associated with current behavior change attempts. Conclusion: This study suggests that physician recommendations are relevant predictors of reported behavior change in individuals with MSD. Although education plays an important role in this association, the relationship is complex and multifaceted. Future studies should explore how compliance may be impacted by other factors, such as physician message type.

RESUMO

This study tested whether a cancer education intervention affected promotores' self-efficacy to deliver an intervention to Hispanics and which psychosocial determinants of promotores influenced the number of Hispanic residents reached by promotores in the subsequent education intervention. A quasi-experimental, pre/post-design with a treatment group (no control) assessed differences for promotores (n = 136) before and after exposure to the cancer education intervention. The design also included a cross-sectional evaluation of the number of residents promotores reached with the educational intervention. After being trained, the promotores delivered the intervention to Hispanic residents (n = 1,469). Paired t-tests demonstrated increases in promotores' self-efficacy from pre- to post-intervention. Regression models assessed associations between the numbers of residents reached and select psychosocial determinants of promotores. Age and promotores' years of experience influenced their delivery of a cervical cancer education intervention to Hispanics, but not their delivery of breast or colorectal cancer education interventions. This is the first study to examine which psychosocial determinants influence promotores delivery of cancer education interventions. The outcomes potentially have implications for CHW interventions and training by examining this potential connection between CHWs' psychosocial determinants and intervention outcomes.

RESUMO

The COVID-19 pandemic has required the professional healthcare workforce not only to adjust methods of delivering care safely but also act as a trusted sources of information during a time of uncertainty and rapid research and discovery. The Community Health Worker COVID-19 Impact Survey is a cross-sectional study developed to better understand the impact of COVID-19 on this sector of the healthcare workforce, including training needs of those working through the pandemic. The survey was distributed in Texas, New Mexico, and Arizona. This study focuses on Texas, and the data presented (n = 693) is a sub-set of qualitative data from the larger survey. Results of the content analysis described in this paper are intended to inform current COVID-19-related CHW training curriculum, in addition to future infectious disease prevention and preparedness response trainings.

RESUMO

BACKGROUND: It has been recognized that the availability of foods in the home are important to nutritional health, and may influence the dietary behavior of children, adolescents, and adults. It is therefore important to understand food choices in the context of the household setting. Considering their importance, the measurement of household food resources becomes critical.Because most studies use a single point of data collection to determine the types of foods that are present in the home, which can miss the change in availability within a month and when resources are not available, the primary objective of this pilot study was to examine the feasibility and value of conducting weekly in-home assessments of household food resources over the course of one month among low-income Mexicano families in Texas colonias. METHODS: We conducted five in-home household food inventories over a thirty-day period in a small convenience sample; determined the frequency that food items were present in the participating households; and compared a one-time measurement with multiple measurements.After the development and pre-testing of the 252-item culturally and linguistically- appropriate household food inventory instrument that used direct observation to determine the presence and amount of food and beverage items in the home (refrigerator, freezer, pantry, elsewhere), two trained promotoras recruited a convenience sample of 6 households; administered a baseline questionnaire (personal info, shopping habits, and food security); conducted 5 in-home assessments (7-day interval) over a 30-day period; and documented grocery shopping and other food-related activities within the previous week of each in-home assessment. All data were collected in Spanish. Descriptive statistics were calculated for mean and frequency of sample characteristics, food-related activities, food security, and the presence of individual food items. Due to the small sample size of the pilot data, the Friedman Test and Kendall's W were used to assess the consistency of household food supplies across multiple observations. RESULTS: Complete data were collected from all 6 Mexicano women (33.2y +/- 3.3; 6.5 +/- 1.5 adults/children in household (HH); 5 HH received weekly income; and all were food insecure. All households purchased groceries within a week of at least four of the five assessments. The weekly presence and amounts of fresh and processed fruits and vegetables, dairy, meats, breads, cereals, beverages, and oils and fats varied. Further, the results revealed the inadequacy of a one-time measurement of household food resources, compared with multiple measures. The first household food inventory as a one-time measure would have mistakenly identified at least one-half of the participant households without fresh fruit, canned vegetables, dairy, protein foods, grains, chips, and sugar-sweetened beverages. CONCLUSIONS: This study highlights the value of documenting weekly household food supplies, especially in households where income resources may be more volatile. Clearly, the data show that a single HFI may miss the changes in availability--presence and amount--that occur among low-income Mexicano households who face challenges that require frequent purchase of foods and beverages. Use of multiple household food inventories can inform the development and implementation of nutrition-related policies and culturally sensitive nutrition education programs.

RESUMO

BACKGROUND: High-density lipoprotein (HDL) levels are inversely associated with cardiovascular risk. Cholesteryl ester transfer protein inhibition with evacetrapib results in a marked increase in HDL and reduction in low-density lipoprotein (LDL) levels. We evaluated the impact of treatment with evacetrapib versus placebo in the subset of 8236 patients with diabetes mellitus (DM) enrolled in the Assessment of Clinical Effects of Cholesteryl Ester Transfer Protein Inhibition with Evacetrapib in Patients at a High Risk for Vascular Outcomes trial. METHODS AND RESULTS: Time to first occurrence of any component of the primary composite endpoint of cardiovascular death, myocardial infarction, stroke, revascularization, and hospitalization for unstable angina was compared among patients with DM randomized to treatment with evacetrapib (n=4127) or placebo (n=4109) over a median of 26 months of follow-up. The mean baseline LDL at initiation was 80 mg/dL with a mean baseline HDL of 44 mg/dL. In patients with DM, evacetrapib resulted in a 131% mean increase in HDL levels and a 32% mean decrease in LDL at 3 months that was sustained during the course of the trial. At 6 months, hemoglobin A1c (HbA1c) levels were lower with evacetrapib than placebo (7.08% vs 7.15%, p=0.023). Composite event rates were higher in patients with DM than without DM (Kaplan-Meier estimates: 15.2% vs 10.6%, HR 1.46, 95% CI 1.30 to 1.64, p<0.001). In the DM group, event rates for the composite endpoint (14.5% evacetrapib vs 16% placebo, HR 0.95, 95% CI 0.85 to 1.07, p=0.38) and individual components of the composite were similar for both evacetrapib and placebo groups. No significant treatment interaction between treatment assignment and diabetes status was noted. CONCLUSION: Despite a favorable increase in HDL, and decreases in LDL and HbA1c levels in patients with DM, we observed no benefits of treatment with evacetrapib on prespecified clinical outcomes in this high-risk population.

RESUMO

Importance: Although lipoprotein(a) (Lp[a]) is a causal genetic risk factor for atherosclerotic cardiovascular disease, it remains unclear which patients with established atherosclerotic cardiovascular disease stand to benefit the most from Lp(a) lowering. Whether inflammation can modulate Lp(a)-associated cardiovascular (CV) risk during secondary prevention is unknown. Objective: To examine whether Lp(a)-associated CV risk is modulated by systemic inflammation in optimally treated patients at high risk of CV disease. Design, Setting, and Participants: A prespecified secondary post hoc analysis of the double-blind, multicenter randomized clinical Assessment of Clinical Effects of Cholesteryl Ester Transfer Protein Inhibition With Evacetrapib in Patients at a High Risk for Vascular Outcomes (ACCELERATE) trial was conducted between October 1, 2012, and December 31, 2013; the study was terminated October 12, 2015. The study was conducted at 543 academic and community hospitals in 36 countries among 12 092 patients at high risk of CV disease (acute coronary syndrome, stroke, peripheral arterial disease, or type 2 diabetes with coronary artery disease) with measurable Lp(a) and high-sensitivity C-reactive protein (hsCRP) levels during treatment. Statistical analysis for this post hoc analysis was performed from September 26, 2018, to March 28, 2020. Interventions: Participants received evacetrapib, 130 mg/d, or matching placebo. Main Outcomes and Measures: The ACCELERATE trial found no significant benefit or harm of evacetrapib on 30-month major adverse cardiovascular events (CV death, myocardial infarction [MI], stroke, coronary revascularization, or hospitalization for unstable angina). This secondary analysis evaluated rates of CV death, MI, and stroke across levels of Lp(a). Results: High-sensitivity C-reactive protein and Lp(a) levels were measured in 10 503 patients (8135 men; 8561 white; 10 134 received concurrent statins; mean [SD] age, 64.6 [9.4] years). In fully adjusted analyses, in patients with hsCRP of 2 mg/L or more but not less than 2 mg/L, increasing quintiles of Lp(a) were significantly associated with greater rates of death, MI, and stroke (P = .006 for interaction). Each unit increase in log Lp(a) levels was associated with a 13% increased risk of CV death, nonfatal MI, or stroke only in those with hsCRP levels of 2 mg/L or more (P = .008 for interaction). There was also a significant stepwise relationship between increasing Lp(a) quintiles and time to first CV death, MI, or stroke (log-rank P < .001) when hsCRP levels were 2 mg/L or more but not less than 2 mg/L. Sensitivity analyses in the ACCELERATE placebo-treated group yielded similar significant associations exclusively in the group with hsCRP of 2 mg/L or more. Conclusions and Relevance: Elevated Lp(a) levels during treatment are related to CV death, MI, and stroke when hsCRP levels are 2 mg/L or more but not less than 2mg/L. This finding suggests a potential benefit of lowering Lp(a) in patients with residual systemic inflammation despite receipt of optimal medical therapy.

RESUMO

Importance: Visit-to-visit blood pressure variability (BPV) is associated with cardiovascular events, but mechanisms and therapeutic implications underlying this association are not well understood. Objective: To examine the association of intraindividual BPV, coronary atheroma progression, and clinical outcomes using serial intravascular ultrasonography. Design, Setting, and Participants: Post hoc patient-level analysis of 7 randomized clinical trials conducted from 2004 to 2016 involving 3912 patients in multicenter, international, clinic-based primary and tertiary care centers. Adult patients with coronary artery disease who underwent serial intravascular ultrasonography in the setting of a range of medical therapies were included. Data were analyzed between November 2017 and March 2019. Exposures: Visit-to-visit BPV measured using intraindividual standard deviation over 3, 6, 12, 18, and 24 months. Main Outcomes and Measures: Percent atheroma volume (PAV) progression and major adverse cardiovascular events (defined as death, myocardial infarction, stroke, urgent revascularization for acute coronary syndrome, and hospitalization for unstable angina). Results: Of 3912 patients, the mean (SD) age was 58 (9) years, 1093 (28%) were women, and 3633 (93%) were white . Continuous change in PAV was significantly associated with systolic BPV (ß, .049; 95% CI, 0.021-0.078; P = .001), diastolic BPV (ß, .031; 95% CI, 0.002-0.059; P = .03), and pulse pressure variability (ß, .036; 95% CI, 0.006-0.067; P = .02), without a signal for differential effect greater than or less than a mean BP of 140/90 mm Hg. The PAV progression as a binary outcome was significantly associated with systolic BPV (odds ratio, 1.09; 95% CI, 1.01-1.17; P = .02) but not diastolic BPV (odds ratio, 1.04; 95% CI, 0.97-1.11; P = .30) or pulse pressure variability (odds ratio, 1.03; 95% CI, 0.96-1.10; P = .47). Survival curves revealed a significant stepwise association between cumulative major adverse cardiovascular events and increasing quartiles of systolic BPV (Kaplan-Meier estimates for quartiles 1-4: 6.1% vs 8.5% vs 10.1% vs 12.0%, respectively; log-rank P <.001). These distinct stepwise associations were not seen with diastolic BPV or pulse pressure variability. Conclusions and Relevance: Greater BPV, particularly systolic BPV, is significantly associated with coronary atheroma progression and adverse clinical outcomes. These data suggest maintaining stable blood pressure levels may be important to further improve outcomes in patients with coronary disease.

RESUMO

Older adult falls continue to be a public health priority across the United States-Massachusetts (MA) being no exception. The MA Prevention and Wellness Trust Fund (PWTF) program within the MA Department of Public Health aims to reduce the physical and economic burdens of chronic health conditions by linking evidence-based clinical care with community intervention programs. The PWTF partnerships that focused on older adult falls prevention integrated the Centers for Disease Control and Prevention's Stopping Elderly Accidents, Death and Injuries toolkit into clinical settings. Partnerships also offer referrals for home safety assessments, Tai Chi, and Matter of Balance programs. This paper describes the PWTF program implementation process involving 49 MA organizations, while highlighting the successes achieved and lessons learned. With the unprecedented expansion of the U.S. Medicare beneficiary population, and the escalating incidence of falls, widespread adoption of effective prevention strategies will become increasingly important for both public health and for controlling healthcare costs. The lessons learned from this PWTF initiative offer insights and recommendations for future falls prevention program development and implementation.

RESUMO

We explored for geographic variations in coronary atheroma progression rates in the United States compared to other world regions (Canada, Latin America, Western Europe, and Central-Eastern Europe) and sought to ascertain if this associated with regional differences in major adverse cardiovascular events (MACE; cardiovascular death, nonfatal myocardial infarction, coronary revascularization). Across 7 randomized trials with a global recruitment pattern, 5,451 participants with angiographic coronary disease underwent serial coronary intravascular ultrasonography during 18 or 24 months, with adjudicated MACE. Change in coronary percent atheroma volume (ΔPAV) and MACE in the United States versus other world regions were assessed. Despite similar baseline angiographic and plaque characteristics across participants and regions, following propensity-weighted and multivariate analysis, US (n = 3,706) versus non-US (n = 1,745) participants demonstrated marginal but significantly greater annualized ΔPAV (least-square means ± SE: 0.27 ± 0.14% vs 0.062 ± 0.14%, p = 0.005). However, MACE rates were disproportionately higher in US compared to non-US participants (23.5% vs 10.9%, p <0.001), driven by a doubling in crude rates of coronary revascularization procedures (16.1% vs 7.8%, p <0.001). The US participants hospitalized with unstable angina demonstrated more significant disease progression than their non-US counterparts (ΔPAV: 0.57 ± 0.19% vs -0.30 ± 0.36%, p = 0.033) and greater MACE (9.1% vs 4.8%, p <0.001). A US geographic disposition independently associated with MACE (hazard ratio 1.53, 95% confidence interval 1.22 to 1.92, p <0.001). In conclusion, in participants with stable coronary disease, coronary atheroma progression rates are modestly higher in US-based compared to non-US-based participants. Elective coronary revascularization rates however are disproportionately greater in US-based participants.

RESUMO

The total cholesterol to high-density lipoprotein cholesterol (TC/HDL-C) ratio may quantify atherogenic lipoproteins beyond low-density lipoprotein cholesterol (LDL-C), non-HDL-C and apolipoprotein B (apoB). We analyzed pooled data from 9 trials involving 4,957 patients with coronary artery disease undergoing serial intravascular ultrasonography to assess changes in percent atheroma volume (ΔPAV) and 2-year major adverse cardiovascular event (MACE) rates when TC/HDL-C levels were discordant with LDL-C, non-HDL-C, and apoB. Discordance was investigated when lipid levels were stratified by

RESUMO

The diagnosis of heparin-induced thrombocytopenia (HIT) can be challenging. The HIT Expert Probability (HEP) Score has recently been proposed to aid in the diagnosis of HIT. We sought to externally and prospectively validate the HEP score. We prospectively assessed pre-test probability of HIT for 51 consecutive patients referred to our Consultative Service for evaluation of possible HIT between August 1, 2012 and February 1, 2013. Two Vascular Medicine fellows independently applied the 4T and HEP scores for each patient. Two independent HIT expert adjudicators rendered a diagnosis of HIT likely or unlikely. The median (interquartile range) of 4T and HEP scores were 4.5 (3.0, 6.0) and 5 (3.0, 8.5), respectively. There were no significant differences between area under receiver-operating characteristic curves of 4T and HEP scores against the gold standard, confirmed HIT [defined as positive serotonin release assay and positive anti-PF4/heparin ELISA] (0.74 vs 0.73, p = 0.97). HEP score ≥ 2 was 100 % sensitive and 16 % specific for determining the presence of confirmed HIT while a 4T score > 3 was 93 % sensitive and 35 % specific. In conclusion, the HEP and 4T scores are excellent screening pre-test probability models for HIT, however, in this prospective validation study, test characteristics for the diagnosis of HIT based on confirmatory laboratory testing and expert opinion are similar. Given the complexity of the HEP scoring model compared to that of the 4T score, further validation of the HEP score is warranted prior to widespread clinical acceptance.
