Abstract
PURPOSE OF REVIEW Research on sex and gender aspects cardiovascular disease has contributed to a reduction in cardiovascular mortality in women. However, cardiovascular disease remains the leading cause of death of women in the United States. Disparities in cardiovascular risk and outcomes among women overall persist and are amplified for women of certain ethnic and racial subgroups. We review the evidence of racial and ethnic differences in cardiovascular risk and care among women and describe a path forward to achieve equitable cardiovascular care for women of racial and ethnic minority groups. RECENT FINDINGS There is a disproportionate effect on cardiovascular outcomes in women and certain racial and ethnic groups in part due to disparities in triage, diagnosis, treatment, which lead to amplification of inequalities in women of minority racial and ethnic background. Data suggest gender and racial bias, underappreciation of nontraditional risk factors, underrepresentation of women in clinical trials and undertreatment of disease contributes to persistent differences in cardiovascular disease outcomes in women of color. Understanding the myriad of factors that contribute to increased cardiovascular risk, and disparities in treatment and outcomes among women from racial/ethnic minority backgrounds is imperative to improving cardiovascular care for this patient population.

Abstract
The overall incidence of Out-of-hospital Cardiac Arrest (OHCA) is decreasing worldwide due to emergency responses, but there are gender and racial differences in the incidence of OHCA, which remain under investigation. Our aim was to identify the incidence, gender, and racial disparities in patients admitted with OHCA. The National Inpatient Sample Database is one of the largest all-payer inpatient database. It was queried to identify patients 18 years or older who were hospitalized with the principal diagnosis of OHCA. There was a total of 85,988 patients who were discharged with a diagnosis classified as OHCA using the ICD-9 code for a period of 2 years. The mean age of the patients who had presented to the hospital with OHCA was 64.3 (±18.5 years). Overall, a greater number of males suffered from OHCA were compared with female population of (48,635 vs 37,366; P < 0.0001). The incidence of OHCA was higher among Caucasians as compared with African Americans (54,812, 63.8% vs 13,787, 16%; P < 0.0001). In-hospital deaths after OHCA were 43,024 (50%). But African Americans had higher mortality than Caucasians after hospitalization for OHCA (adjusted odds ratio, 1.23; 95% confidence interval, 1.18-1.26; P < 0.01). We observed significant differences in gender and racial factors in the patients who were admitted to the hospital with a diagnosis of OHCA based on an analysis of the national inpatient database.

The Impact of Race on Outcomes of Revascularization for Multivessel Coronary Artery Disease. Ann Thorac Surg 2020; 111:1983-1990. [PMID: 33038339 DOI: 10.1016/j.athoracsur.2020.08.005] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/10/2020] [Revised: 07/01/2020] [Accepted: 08/04/2020] [Indexed: 11/20/2022]
Abstract
BACKGROUND Racial disparities exist between Black and White patients with coronary artery disease with regard to access to revascularization, preprocedural comorbidities, and postprocedural outcomes. This study investigated the differences in the treatment of multivessel coronary artery disease (MVCAD) and long-term outcomes between Black and White patients. METHODS This was a propensity-matched retrospective analysis that utilized pooled institutional data from a large, multihospital health care system. It included Black and White patients who underwent coronary revascularization for MVCAD between 2011 and 2018. RESULTS A total of 6005 patients were included (5689 White and 316 Black). In the unmatched cohort, Black patients had a higher incidence of preexisting comorbidities such as diabetes, dialysis dependence, peripheral arterial disease, heart failure, and underwent percutaneous coronary intervention (PCI) more frequently. Five-year overall survival was similar, but Black patients experienced higher rates of major adverse cardiac and cerebrovascular events and repeat revascularization. Propensity matching resulted in a sample of 926 (312 Black, 614 White) patients that were well matched. In the matched analysis, Black patients underwent PCI more frequently and a had higher rate of stoke. Five-year survival, major adverse cardiac and cerebrovascular events and repeat revascularization rates were comparable. CONCLUSIONS Black patients with MVCAD have a higher comorbidity burden and undergo PCI at higher rates. After adjusting for baseline differences, Black patients still had higher rates of PCI utilization and long-term stroke. It is possible that a significant portion of racial disparities in MVCAD are driven by differences in baseline risk; however, there is evidence of possible racial bias with regard to revascularization strategies.

CARDIOVASCULAR REVASCULARIZATION MEDICINE 2020; 21:1016-1021. [PMID: 31992531 DOI: 10.1016/j.carrev.2019.12.026] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2019] [Revised: 12/19/2019] [Accepted: 12/19/2019] [Indexed: 01/23/2023]
Abstract
BACKGROUND Poverty is associated with a higher risk of myocardial infarction and cardiac death, both of which are decreased by treatment of hyperlipidemia. There may be differences in the appropriate treatment of hyperlipidemia between richer and poorer Americans. In this study, we aimed to evaluate the association between income level and appropriate lipid-lowering therapy. METHODS We identified outpatient visits in the National Cardiovascular Data Registry's Practice Innovation and Clinical Excellence (PINNACLE) Registry and determined appropriateness of lipid-lowering therapy among patients in different income quintiles (Quintile 5 being the highest income quintile). Logistic regression at the patient level was performed to evaluate the independent association of income and the primary outcome of appropriate statin therapy. The analysis was repeated before and after November 2013 given a change in guideline definitions. RESULTS The study included 1,655,723 patients. Overall, 68-73% of patients were treated appropriately under the ATP III Guidelines and 57-62% of patients were treated appropriately under the ACC/AHA Guidelines. Patients in the wealthiest quintile had higher odds of appropriate statin therapy under both guidelines relative to patients in the poorest quintile (OR 1.06 [1.05-1.07] for ATP III and OR 1.03 [1.01-1.04] for ACC/AHA). In the whole sample, patients with higher estimated income had a small but significant increased likelihood of appropriate statin therapy (point-biserial correlation 0.035 [p < 0.001] for ATP III and 0.026 [p < 0.001] for ACC/AHA). CONCLUSIONS Here we describe a small association between appropriate statin use and income. Further investigation into barriers in the use of evidence-based therapies in poorer populations is needed.

Abstract
Objectives We sought to evaluate whether socioeconomic status influences outcome after first-time transcatheter aortic valve implantation (TAVI). Method This is a single-centre study carried out in Swansea, South West Wales, UK between 5 November 2009 and 10 June 2018. Data included age, gender, domiciliary postal code, comorbidities, complications post-TAVI, length of stay, follow-up time and survival status. The Welsh Index of Multiple Deprivation, 2014 was used to stratify cases by level of social deprivation according to domiciliary postal codes. Results Study population was 387 patients of whom 213 (54.8%) were men with mean age ±SD of 82.8±8.3 years. Patients, who were less deprived (296 (76.4%)), were more likely to be older (83.5±7.9 vs 80.4±9.3, p<0.05) and to be married (83.2% vs 69.7%, p<0.05). Conversely, ‘more deprived’ patients (91 (23.6%)) were more likely to have a longer stay in hospital as compared with patients in the ‘less deprived group’ (29.6±32.7 days vs 21.3±21.1 days, p<0.05). However, 30-day, 1-year and 3-year survival/mortality rates were similar across all socioeconomic levels. Conclusions This is the first study in which social deprivation has been investigated as a risk factor for mortality in a high-risk group of patients with severe aortic stenosis undergoing TAVI. Residing in a ‘more deprived’ area in South West Wales is not associated with adverse outcome following TAVI but patients who are ‘more deprived’ tend to stay longer in hospital compared with patients who are ‘less deprived’.

Abstract
Background Coronary artery disease is common, and there exist disparities in management and outcomes. The purpose of this study is to examine the association between ambulatory care utilizations and inpatient acute myocardial infarction (AMI) mortality. Methods and Results This is a retrospective analysis of a stratified national sample of Medicare fee‐for‐service enrollees aged 66 years and older from January 1, 2010 to December 31, 2011. We measured both number of ambulatory visits and presence of ambulatory cardiac tests. The primary outcome was inpatient AMI mortality. Using multivariate logistic regression models, we estimated the association between ambulatory care utilization and the main patient outcomes, adjusting for patient‐ and area‐level demographic, geographical, and clinical characteristics. We found that a significantly lower percentage of Hispanics and Asians, relative to whites, had frequent ambulatory care visits. Among the largest 4 race/ethnic groups, Asians had the highest observed inpatient mortality rate (15.9%). Overall, low ambulatory utilization was associated with higher odds (odds ratio=1.85 [95% confidence interval: 1.11‐3.08]), and ambulatory cardiac testing was associated with lower odds (odds ratio=0.73 [0.55‐0.95]) of inpatient AMI mortality, after adjustment for covariates. Asians had higher odds of inpatient AMI mortality even after adjustment for covariates. Conclusions Among Medicare fee‐for‐service enrollees, Hispanics and Asians had lower rates of ambulatory care visits, and all minority groups had higher odds of hospitalization for AMI. Ambulatory care utilization, including both ambulatory clinic visits and outpatient cardiac tests, were associated with AMI mortality. Further research is needed to understand the causal relationship between ambulatory care utilization and cardiovascular outcomes.

Abstract
BACKGROUND Poor patients have greater morbidity and die up to 10 years earlier than patients who have higher socio-economic status. These findings are often attributed to differences in life-style between groups. The present study aimed at investigating the extent to which physicians contribute to the effect by providing relative poorer care, resulting in relative neglect in terms of time spent with a poor patient and more inaccurate diagnoses. METHODS A randomised experiment with 45 internal medicine residents. Doctors diagnosed 12 written clinical vignettes that were exactly the same except for the description of the patients' socio-economic status. Each participant diagnosed four of the vignettes in a poor-patient version, four in a rich-patient version, and four in a version that did not contain socio-economic markers, in a balanced within-subjects incomplete block design. Main measurements were: diagnostic accuracy scores and time spent on diagnosis. RESULTS Mean diagnostic accuracy scores (range 0-1) did not significantly differ among the conditions of the experiment (for poor patients: 0.48; for rich patients: 0.52; for patients without socio-economic markers: 0.54; p > 0.05). While confronted with patients not presenting with socio-economic background information, the participants spent significantly less time-to-diagnosis ((for poor patients: 168 s; for rich patients: 176 s; for patients without socio-economic markers: 151 s; p < 0.01), however due to the fact that the former vignettes were shorter. CONCLUSION There is no reason to believe that physicians are prejudiced against poor patients and therefore treat them differently from rich patients or patients without discernible socio-economic background.

Abstract
Background: Contralateral prophylactic mastectomy (CPM) treatments have been on the rise among white women with early stage unilateral breast cancer who have a higher socioeconomic status (SES) and private insurance. Low income and uninsured women are not choosing CPM at the same rate. The purpose of this study was to evaluate the socioeconomic factors related to the choice of surgical treatment in women diagnosed with unilateral breast cancer in the state of New Jersey. Materials and Methods: This retrospective study of 10 years of breast cancer data abstracted from the New Jersey State Cancer Registry utilized bivariate analyses and two multivariate logistic regression models to analyze the effect of socioeconomics on choice of surgical treatment. Results: In New Jersey, 52,529 women were treated for breast cancer from 2004 to 2014. CPM rates increased gradually over time from 3.72% in 2004 to 10.82% in 2014 with women more likely to choose CPM if they were younger, white, and had private insurance (p < 0.001). The single factor that was most predictive of choosing CPM was access to immediate reconstruction (odds ratio 2.36, confidence interval 2.160-2.551). Women with low SES were much less likely to choose CPM. Conclusions: Results of this study may provide incentive for researchers to assess the impact of culture, race/ethnicity, and socioeconomics on a woman's interactions with health care providers so as to allow all women regardless of SES to express their needs, concerns, and wishes when confronted with a breast cancer diagnosis.

Abstract
BACKGROUND Prior research documents gender gaps in cardiovascular risk management, with women receiving poorer quality routine care on average, even in managed care systems. Although population health management tools and quality improvement efforts have led to better overall care quality and narrowing of racial/ethnic gaps for a variety of measures, we sought to quantify persistent gender gaps in cardiovascular risk management and to assess the performance of routinely used commercial population health management tools in helping systems narrow gender gaps. METHODS Using 2013 through 2014 claims and enrollment data from more than 1 million members of a large national health insurance plan, we assessed performance on seven evidence-based quality measures for the management of coronary artery disease and diabetes mellitus, a cardiac risk factor, across and within four metropolitan areas. We used logistic regression to adjust for region, demographics, and risk factors commonly tracked in population health management tools. FINDINGS Low-density lipoprotein (LDL) cholesterol control (LDL < 100 mg/dL) rates were 5 and 15 percentage points lower for women than men with diabetes mellitus (p < .0001), and coronary artery disease (p < .0001), respectively. Adjusted analyses showed women were more likely to have gaps in LDL control, with an odds ratio of 1.31 (95% confidence interval, 1.27-1.38) in diabetes mellitus and 1.88 (95% confidence interval, 1.65-2.10) in coronary artery disease. CONCLUSIONS Given our findings that gender gaps persist across both clinical and geographic variation, we identified additional steps health plans can take to reduce disparities. For measures where gaps have been consistently identified, we recommend that gender-stratified quality reporting and analysis be used to complement widely used algorithms to identify individuals with unmet needs for referral to population health and wellness behavior support programs.

Abstract
Background Acute myocardial infarction (AMI) is a common high-risk disease with inpatient mortality of 5% nationally. But little is known about this outcome among Asian Americans (Asians), a fast growing racial/ethnic minority in the country. The objectives of the study are to obtain near-national estimates of differences in AMI inpatient mortality between minorities (including Asians) and non-Hispanic Whites and identify comorbidities and sociodemographic characteristics associated with these differences. Method This is a retrospective analysis of 2010–2011 state inpatient discharge data from 10 states with the largest share of Asian population. We identified hospitalization with a primary diagnosis of AMI using the ICD-9 code and used self-reported race/ethnicity to identify White, Black, Hispanic, and Asian. We performed descriptive analysis of sociodemographic characteristics, medical comorbidities, type of AMI, and receipt of cardiac procedures. Next, we examined overall inpatient AMI mortality rate based on patients’ race/ethnicity. We also examined the types of AMI and a receipt of invasive cardiac procedures by race/ethnicity. Lastly, we used sequential multivariate logistic regression models to study inpatient mortality for each minority group compared to Whites, adjusting for covariates. Results Over 70% of the national Asian population resides in the 10 states. There were 496,472 hospitalizations with a primary diagnosis of AMI; 75% of all cases were Whites, 10% were Blacks, 12% were Hispanics, and 3% were Asians. Asians had a higher prevalence of cardiac comorbidities, including hypertension, diabetes, and kidney failure compared to Whites (p-value< 0.01). There were 158,623 STEMI (ST-elevation AMI), and the proportion of hospitalizations for STEMI was the highest for Asians (35.2% for Asians, 32.7% for Whites, 25.3% for Blacks, and 32.1% for Hispanics). Asians had the highest rates of inpatient AMI mortality: 7.2% for Asians, 6.3% for Whites, 5.4% for Blacks, and 5.9% for Hispanics (ANOVA p-value < 0.01). In adjusted analyses, Asians (OR = 1.11 [95% CI: 1.04–1.19]) and Hispanics (OR = 1.14 [1.09–1.19]) had a higher likelihood of inpatient mortality compared to Whites. Conclusions Asians had a higher risk-adjusted likelihood of inpatient AMI mortality compared to Whites. Further research is needed to identify the underlying reasons for this finding to improve AMI disparities for Asians.

Abstract
OBJECTIVES To evaluate potential gaps in preventive medical therapy and healthy lifestyle practices among symptomatic patients with suspected coronary artery disease (CAD) seeing primary care physicians and cardiologists and how gaps vary by sociodemographic characteristics and baseline cardiovascular risk. DESIGN Cross-sectional study assessing potential preventive gaps. PARTICIPANTS 10 003 symptomatic outpatients evaluated by primary care physicians, cardiologists or other specialists for suspected CAD. SETTING PROspective Multicenter Imaging Study for Evaluation of Chest Painfrom 2010 to 2014. MEASURES Primary measures were absence of an antihypertensive, statin or angiotensin-converting enzyme inhibitor/angiotensin receptor blocker for renal protection in patients with hypertension, dyslipidaemia or diabetes, respectively, and being sedentary, smoking or being obese. RESULTS Preventive treatment gaps affected 14% of patients with hypertension, 36% of patients with dyslipidaemia and 32% of patients with diabetes. Overall, 49% of patients were sedentary, 18% currently smoked and 48% were obese. Women were significantly more likely to not take a statin for dyslipidaemia and to be sedentary. Patients with lower socioeconomic status were also significantly more likely to not take a statin. Compared with Whites, Blacks were significantly more likely to be obese, while Asians were less likely to smoke or be obese. High-risk patients sometimes experienced larger preventive care gaps than low-risk patients. For patients with dyslipidaemia, the presence of a treatment gap was associated with a higher risk of an adverse event (HR 1.35, 95% CI 1.02 to 1.82). CONCLUSIONS Among contemporary, symptomatic patients with suspected CAD, significant gaps exist in preventive care and lifestyle practices, and high-risk patients sometimes had larger gaps. Differences by sex, age, race/ethnicity, socioeconomic status and geography are modest but contribute to disparities and have implications for improving opulation health. For patients with dyslipidaemia, the presence of a treatment gap was associated with a higher risk of an adverse event. CLINICAL TRIAL REGISTRATION Clinical Trials.gov identifier NCT01174550.

Socially disadvantaged city districts show a higher incidence of acute ST-elevation myocardial infarctions with elevated cardiovascular risk factors and worse prognosis. BMC Cardiovasc Disord 2017; 17:254. [PMID: 28938873 PMCID: PMC5610462 DOI: 10.1186/s12872-017-0683-2] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2017] [Accepted: 09/11/2017] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The importance of socioeconomic status (SES) for coronary heart disease (CHD)-morbidity is subject of ongoing scientific investigations. This study was to explore the association between SES in different city-districts of Bremen/Germany and incidence, severity, treatment modalities and prognosis for patients with ST-elevation myocardial infarctions (STEMI). METHODS Since 2006 all STEMI-patients from the metropolitan area of Bremen are documented in the Bremen STEMI-registry. Utilizing postal codes of their home address they were assigned to four groups in accordance to the Bremen social deprivation-index (G1: high, G2: intermediate high, G3: intermediate low, G4: low socioeconomic status). RESULTS Three thousand four hundred sixty-two consecutive patients with STEMI admitted between 2006 and 2015 entered analysis. City areas with low SES showed higher adjusted STEMI-incidence-rates (IR-ratio 1.56, G4 vs. G1). This elevation could be observed in both sexes (women IRR 1.63, men IRR 1.54) and was most prominent in inhabitants <50 yrs. of age (women IRR 2.18, men IRR 2.17). Smoking (OR 1.7, 95%CI 1.3-2.4) and obesity (1.6, 95%CI 1.1-2.2) was more prevalent in pts. from low SES city-areas. While treatment-modalities did not differ, low SES was associated with more extensive STEMIs (creatine kinase > 3000 U/l, OR 1.95, 95% CI 1.4-2.8) and severe impairment of LV-function post-STEMI (OR 2.0, 95% CI 1.2-3.4). Long term follow-up revealed that lower SES was associated with higher major adverse cardiac or cerebrovascular event (MACCE)-rates after 5 years: G1 30.8%, G2 35.7%, G3 36.0%, G4 41.1%, p (for trend) = 0.02. This worse prognosis could especially be shown for young STEMI-patients (<50 yrs. of age) 5-yr. mortality-rates(G4 vs. G1) 18.4 vs. 3.1%, p = 0.03 and 5-year-MACCE-rates (G4 vs. G1) 32 vs. 6.3%, p = 0.02. CONCLUSIONS This registry-data confirms the negative association of low socioeconomic status and STEMI-incidence, with higher rates of smoking and obesity, more extensive infarctions and worse prognosis for the socio-economically deprived.

Abstract
Coronary artery disease is the leading cause of death in women. Women with ST-segment elevation myocardial infarctions continue to have worse outcomes compared with men despite advancements in therapies. Furthermore, these differences are particularly pronounced among young men and women with myocardial infarctions. Differences in the pathophysiology of coronary artery plaque development, disease presentation, and recognition likely contribute to these outcome disparities. Despite having worse outcomes compared with men, women clearly benefit from aggressive treatment and the latest therapies. This article reviews the treatment options for ST-segment elevation myocardial infarctions and the outcomes of women after treatment with reperfusion therapies.

Abstract
BACKGROUND Lower socioeconomic groups face higher mortality risk, possibly due to a higher burden of cardiovascular risk factors. The independent association between income and survival following cardiac surgery is not known. OBJECTIVES This study sought to investigate the association between household disposable income and long-term mortality after cardiac surgery. METHODS In a Swedish nationwide population-based analysis, we included all patients who underwent cardiac surgery between 1999 and 2012 using a large national registry. Information regarding income, education, marital status, medical history, and cardiovascular risk factors was obtained from data managed by the National Board of Health and Welfare and Statistics Sweden. The adjusted risk for all-cause mortality was estimated using Cox regression by quintiles of household disposable income. RESULTS We included 100,534 patients and, during a mean follow-up of 7.3 years, 29,176 (29%) patients died. There was a stepwise inverse association between household disposable income and all-cause mortality: the adjusted hazard ratio was 0.93 (95% confidence interval [CI]: 0.89 to 0.96), 0.87 (95% CI: 0.84 to 0.91), 0.78 (95% CI: 0.75 to 0.82), and 0.71 (95% CI: 0.67 to 0.75), for the second, third, fourth, and fifth income quintiles, respectively, compared to the first (and lowest) income quintile. The inverse association between income and mortality was consistent through the study period and in selected subgroups, although it was slightly attenuated in older patients. CONCLUSIONS We found a strong inverse association between income and mortality following cardiac surgery in Sweden that was independent of other socioeconomic status variables, comorbidities, and cardiovascular risk profile. Ways to better implement secondary prevention measures should be explored in low-income patient groups. (HeAlth-data Register sTudies of Risk and Outcomes in Cardiac Surgery [HARTROCS]; NCT02276950).

Abstract
Applying a log-logistic accelerated failure time mixed effects model to a sample of 95,504 in-hospital patients with acute myocardial infarction (AMI) between 2005 and 2010 in the United States, we measured the relative contribution of hospitals (vs. patients) in explaining in-hospital AMI mortality. Before adjusting for age, race, income, 29 comorbidities of AMI patients, and primary payer, hospital characteristics explained 19.93% of the variance in AMI in-hospital mortality. After controlling for these, variance explained declined by 5.65%, to 14.28%. These findings have implications for policymakers in assessing hospitals' "responsibility" for AMI patient mortality, for hospitals in allocating resources toward improving AMI patient care, and for medical intermediaries in making liability judgments and payment allocations to hospitals.

Abstract
Socioeconomic status (SES) as reflected by residential zip code may adversely influence outcomes for patients with acute pulmonary embolism (PE). We sought to analyze the impact of neighborhood SES on in-hospital mortality, use of thrombolysis, implantation of inferior vena cava (IVC) filters and cost of hospitalization following acute PE. We used the 2003–2011 Nationwide Inpatient Sample (NIS) for this analysis. All hospital admissions with a principal diagnosis of acute PE were identified using ICD-9 codes. Neighborhood SES was assessed using median household income of the residential zip code for each patient. Over this 9-year period, 276,484 discharges with acute PE were analyzed. There was a progressive decrease in in-hospital mortality across the SES quartiles ( p-trend <0.001). The incidence of in-hospital mortality across quartiles 1–4 was 3.8%, 3.3%, 3.2%, and 3.1%, respectively. Despite low rates of thrombolytic utilization in this cohort, we observed a progressive increase in the rate of thrombolysis utilization across the SES quartiles (1.5%, 1.6%, 1.7%, 2.0%; p-trend <0.001). There was no significant difference in the use of IVC filters across the SES quartiles ( p-trend=0.9). The mean adjusted cost of hospitalization among quartiles 2, 3, and 4, as compared to quartile 1, was significantly higher by $1202, $1650, and $1844, respectively ( p-trend<0.001). In conclusion, patients residing in zip codes with lower SES had increased in-hospital mortality and decreased utilization of thrombolysis following acute PE compared to patients residing in higher SES zip codes. The cost of hospitalization for patients from higher SES quartiles was significantly higher than those from lower quartiles.

Racial, gender, and socioeconomic status bias in senior medical student clinical decision-making: a national survey. J Gen Intern Med 2015; 30:758-67.

Abstract
BACKGROUND Research suggests stereotyping by clinicians as one contributor to racial and gender-based health disparities. It is necessary to understand the origins of such biases before interventions can be developed to eliminate them. As a first step toward this understanding, we tested for the presence of bias in senior medical students. OBJECTIVE The purpose of the study was to determine whether bias based on race, gender, or socioeconomic status influenced clinical decision-making among medical students. DESIGN We surveyed seniors at 84 medical schools, who were required to choose between two clinically equivalent management options for a set of cardiac patient vignettes. We examined variations in student recommendations based on patient race, gender, and socioeconomic status. PARTICIPANTS The study included senior medical students. MAIN MEASURES We investigated the percentage of students selecting cardiac procedural options for vignette patients, analyzed by patient race, gender, and socioeconomic status. KEY RESULTS Among 4,603 returned surveys, we found no evidence in the overall sample supporting racial or gender bias in student clinical decision-making. Students were slightly more likely to recommend cardiac procedural options for black (43.9 %) vs. white (42 %, p = .03) patients; there was no difference by patient gender. Patient socioeconomic status was the strongest predictor of student recommendations, with patients described as having the highest socioeconomic status most likely to receive procedural care recommendations (50.3 % vs. 43.2 % for those in the lowest socioeconomic status group, p < .001). Analysis by subgroup, however, showed significant regional geographic variation in the influence of patient race and gender on decision-making. Multilevel analysis showed that white female patients were least likely to receive procedural recommendations. CONCLUSIONS In the sample as a whole, we found no evidence of racial or gender bias in student clinical decision-making. However, we did find evidence of bias with regard to the influence of patient socioeconomic status, geographic variations, and the influence of interactions between patient race and gender on student recommendations.

Abstract
INTRODUCTION AND OBJECTIVES The value of socioeconomic status as a prognostic marker in acute myocardial infarction is controversial. The aim of this study was to evaluate the impact of educational level, as a marker of socioeconomic status, on the prognosis of long-term survival after acute myocardial infarction. METHODS We conducted a prospective, observational study of 5797 patients admitted to hospital with acute myocardial infarction. We studied long-term all-cause mortality (median 8.5 years) using adjusted regression models. RESULTS We found that 73.1% of patients had primary school education (n=4240), 14.5% had secondary school education (including high school) (n=843), 7.0% was illiterate (n=407), and 5.3% had higher education (n=307). Patients with secondary school or higher education were significantly younger, more were male, and they had fewer risk factors and comorbidity. These patients arrived sooner at hospital and had less severe heart failure. During admission they received more reperfusion therapy and their crude mortality was lower. Their drug treatment in hospital and at discharge followed guideline recommendations more closely. On multivariate analysis, secondary school or higher education was an independent predictor and protective factor for long-term mortality (hazard ratio=0.85; 95% confidence interval, 0.74-0.98). CONCLUSIONS Our study shows an inverse and independent relationship between educational level and long-term mortality in patients with acute myocardial infarction.

Abstract
Background Socioeconomic status (SES) as reflected by residential zip code status may detrimentally influence a number of prehospital clinical, access‐related, and transport variables that influence outcome for patients with ST‐elevation myocardial infarction (STEMI) undergoing reperfusion. We sought to analyze the impact of SES on in‐hospital mortality, timely reperfusion, and cost of hospitalization following STEMI. Methods and Results We used the 2003–2011 Nationwide Inpatient Sample database for this analysis. All hospital admissions with a principal diagnosis of STEMI were identified using ICD‐9 codes. SES was assessed using median household income of the residential zip code for each patient. There was a significantly higher mortality among the lowest SES quartile as compared to the highest quartile (OR [95% CI]: 1.11 [1.06 to 1.17]). Similarly, there was a highly significant trend indicating a progressively reduced timely reperfusion among patients from lower quartiles (OR [95% CI]: 0.80 [0.74 to 0.88]). In addition, there was a lower utilization of circulatory support devices among patients from lower as compared to higher zip code quartiles (OR [95% CI]: 0.85 [0.75 to 0.97]). Furthermore, the mean adjusted cost of hospitalization among quartiles 2, 3, and 4, as compared to quartile 1 was significantly higher by $913, $2140, and $4070, respectively. Conclusions Patients residing in zip codes with lower SES had increased in‐hospital mortality and decreased timely reperfusion following STEMI as compared to patients residing in higher SES zip codes. The cost of hospitalization of patients from higher SES quartiles was significantly higher than those from lower quartiles.

Abstract
BACKGROUND It is unclear whether gender and racial/ethnic gaps in the use of and patient adherence to β-blockers, angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, and statins after acute myocardial infarction have persisted after establishment of the Medicare Part D prescription program. METHODS AND RESULTS This retrospective cohort study used 2007 to 2009 Medicare service claims among Medicare beneficiaries ≥65 years of age who were alive 30 days after an index acute myocardial infarction hospitalization in 2008. Multivariable logistic regression models examined racial/ethnic (white, black, Hispanic, Asian, and other) and gender differences in the use of these therapies in the 30 days after discharge and patient adherence at 12 months after discharge, adjusting for patient baseline sociodemographic and clinical characteristics. Of 85 017 individuals, 55%, 76%, and 61% used angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, β-blockers, and statins, respectively, within 30 days after discharge. No marked differences in use were found by race/ethnicity, but women were less likely to use angiotensin-converting enzyme inhibitors/angiotensin receptor blockers and β-blockers compared with men. However, at 12 months after discharge, compared with white men, black and Hispanic women had the lowest likelihood (≈30%-36% lower; P<0.05) of being adherent, followed by white, Asian, and other women and black and Hispanic men (≈9%-27% lower; P<0.05). No significant difference was shown between Asian/other men and white men. CONCLUSIONS Although minorities were initially no less likely to use the therapies after acute myocardial infarction discharge compared with white patients, black and Hispanic patients had significantly lower adherence over 12 months. Strategies to address gender and racial/ethnic gaps in the elderly are needed.

Risk factor prevalence and secondary prevention efforts at discharge are well characterized among older patients; however, research is limited for younger and minority AMI populations, particularly among women. METHODS Among 2369 AMI patients enrolled in a 19-center prospective study, we compared the prevalence and cumulative number of five cardiac risk factors (hypertension, hypercholesterolemia, current smoking, diabetes, obesity) by age, sex, and race. We also compared secondary prevention strategies at discharge for these risk factors, including prescription of antihypertensive or lipid-lowering medications and counseling on preventive behaviors (smoking cessation, diabetes management, diet/weight management). RESULTS Approximately 93% of patients had ≥1 risk factor, 72% had ≥2 factors, and 40% had ≥3 factors. The prevalence of multiple risk factors was markedly higher for blacks than for whites within each age-sex group; black women had the greatest risk factor burden of any subgroup (60% of older black women and 54% of younger black women had ≥3 risk factors). Secondary prevention efforts for smoking cessation were less common for black compared with white patients, and younger black patients were less often prescribed antihypertensive and lipid-lowering medications compared with younger white patients. CONCLUSIONS Multiple cardiac risk factors are highly prevalent in AMI patients, particularly among black women. Secondary prevention efforts, however, are less common for blacks compared to whites, especially among younger patients. Our findings highlight the need for improved risk factor modification efforts in these high-risk subgroups.

Socioeconomic disparities in the use of cardioprotective medications among patients with peripheral artery disease: an analysis of the American College of Cardiology's NCDR PINNACLE Registry. J Am Coll Cardiol 2013; 62:51-7. [PMID: 23643497 PMCID: PMC3912073 DOI: 10.1016/j.jacc.2013.04.018] [Citation(s) in RCA: 32] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/07/2013] [Accepted: 04/17/2013] [Indexed: 01/13/2023]
Abstract
OBJECTIVES The aim of this paper was to examine disparities in the use of cardioprotective medications in the treatment of peripheral artery disease (PAD) by socioeconomic status (SES). BACKGROUND PAD is associated with increased cardiovascular risk and is more prevalent among those of lower SES. However, the use of guideline-recommended secondary preventive measures for the treatment of PAD across diverse income subgroups and the influence of practice site on potential treatment disparities by SES are unknown. METHODS Within the National Cardiovascular Disease Registry (NCDR) PINNACLE Registry, 62,690 patients with PAD were categorized into quintiles of SES, as defined by the median income of each patient's zip code. The association between SES and secondary preventive treatment with antiplatelet and statin medications was evaluated using sequential hierarchical modified Poison models, adjusting first for practice site and then for clinical variables. RESULTS Compared with the highest SES quintile (median income: >$60,868), PAD patients in the lowest SES quintile (median income: <$34,486) were treated less often with statins (72.5% vs. 85.8%; RR: 0.84; 95% CI: 0.83 to 0.86; p < 0.001) and antiplatelet therapy (79.0% vs. 84.6%; RR: 0.93; 95% CI: 0.91 to 0.94; p < 0.001). These differences were markedly attenuated after controlling for practice site variation: statins (adjusted RR: 0.97; 95% CI: 0.95 to 0.99; p = 0.003) and antiplatelet therapy (adjusted RR: 0.98; 95% CI: 0.97 to 1.00; p = 0.012). Additional adjustment for patients' clinical characteristics had minimal impact, with slight further attenuation with statins (adjusted RR: 1.00: 95% CI: 0.99 to 1.01; p = 0.772) and antiplatelet therapy (adjusted RR: 1.00; 95% CI: 0.99 to 1.01; p = 0.878). CONCLUSIONS Among PAD patients, the practice site at which patients received care largely explained the observed SES differences in treatment with guideline-recommended secondary preventive medications. Future efforts to reduce treatment disparities in these vulnerable populations should target systems improvement at practices serving high proportions of patients with low SES.

Abstract
The management of ST-segment elevation myocardial infarction (STEMI) has significantly advanced from supportive care to reperfusion therapies with thrombolytics and percutaneous coronary revascularization techniques. These advances have improved the outcomes of patients with STEMI. Although cardiovascular disease is the leading cause of death in both men and women, the minority of patients in trials studying the impact of these therapies on outcomes are women. Multiple studies have shown that men and women do not have equivalent outcomes after STEMI. This article reviews the treatment options for STEMI and the outcomes of women after treatment with reperfusion therapies.

Abstract
PROBLEM STATEMENT Men and women experience pronounced differences in functional decline as they age. The mechanisms behind these differences remain unclear, particularly among chronically ill populations. Drawing on the theory of the disablement process, this research examines sex differences in functional decline, focusing on two mechanisms suggested by the literature to partially mediate these disparities: health behaviors and social support. APPROACH Data from diabetics aged 50 and older from the Health and Retirement Study (n = 2,493) were examined for change in functional status over a 10-year period. Multivariate longitudinal multi-level models were conducted to analyze (1) health behavior (2) social support; and (3) a full model with health behavior and social support together, followed by a separate analysis using sex interaction terms. RESULTS Women and men both experienced functional decline over time. In the models that examined health behaviors and social support separately, women experienced steeper rates of decline. In the full model (which included health behaviors and social support together), men experienced a steeper rate of decline relative to women. The analyses suggest that it is the combination of health and social characteristics (largely through engagement in socially supportive activities that promote health) that are protective against functional decline. CONCLUSION/RECOMMENDATIONS As diabetic men experienced a steeper rate of functional decline than diabetic women once health behaviors and social support were both held constant, future research must examine (a) how these protective factors operate in tandem to protect against disablement of women with diabetes; and (b) how clinical and social policy can promote multi-pronged interventions to improve health behaviors in supportive contexts. Such research will benefit from multi-disciplinary collaborations.

Abstract
Aim. To identify the specifics of acute myocardial infarction (AMI) clinical course and to study the association between clinical outcomes and hospital admission time among elderly patients from Central Asia. Material and methods. In total, 508 AMI patients were divided into the main group (MG), which included 298 men and women aged over 65 years, and the control group (CG; n=210). The analysed parameters included mean time between AMI onset and hospital admission; percentage of patients hospitalised within first 6 hours; percentage of patients administered streptokinase; streptokinase effectiveness; clinical course of AMI; and in-hospital outcomes. Results. Mean hospital admission time was significantly higher in the MG, compared to the CG: 1220±165 vs. 977±88 minutes (p<0,05). Out of 188 MG patients with ST segment elevation, thrombolytic therapy (TLT) was administered to 14,3 %; in the CG (149 patients with ST segment elevation), the respective percentage was 25,5 %. Clinical course of AMI was similar in both groups. However, the MG was characterised by a significantly higher risk of death (9,4 % vs. 2,86 %; F=0,001; OR 3,53, 95 % CI 1,43—8,67), acute heart failure (33,89 % vs. 21,9 %; F=0,001; OR 1,83, 95 % CI 1,22—2,74), or chronic heart failure (41,31 % vs. 24,76 %; F=0,000; OR 2,62, 95 % CI 1,78—3,86). Conclusion. Elderly patients faced a lower chance of myocardial reperfusion, due to later hospital admission and lower TLT effectiveness, and, as a result, had a higher risk of heart failure.

Abstract
BACKGROUND Social status may impact health-related quality of life (HRQOL), hospitalization, and mortality in patients with heart failure (HF). PURPOSE To determine if social status was associated with HRQOL and event-free survival. HYPOTHESES Higher social status (quality of perceived support, emotional support, marital status, and economic status) is related to better HRQOL and event-free survival after controlling covariates (New York Heart Association [NYHA] functional class, comorbidity status, and age). METHODS Patients (N = 147, 61 ± 11 years old, 70% male, 62% NYHA class III/IV) provided data on HRQOL (measured by the Minnesota Living with Heart Failure questionnaire) and social status. Event-free survival data were collected by medical record reviews and patient or family interviews. Hierarchical regression analysis and survival analysis were used to test the hypothesis. RESULTS Better quality of perceived support, better economic status, better functional status, older age, and less comorbidity were related to better HRQOL (R2 = .365, p = <.001). Only economic status predicted event-free survival. CONCLUSION Attention should be given to those who have lower social support to improve HRQOL and those who have lower economic status to improve event-free survival.

Abstract
The long-standing inverse relationship between education and mortality strengthened substantially at the end of the 20th century. This paper examines the reasons for this increase. We show that behavioral risk factors are not of primary importance. Smoking declined more for the better educated, but not enough to explain the trend. Obesity rose at similar rates across education groups, and control of blood pressure and cholesterol increased fairly uniformly as well. Rather, our results show that the mortality returns to risk factors, and conditional on risk factors, the return to education, have grown over time.

Abstract
Homelessness [and poverty] is rapidly escalating across North America and is associated with dire implications for public health and our health care systems. Both are compelling states of existence affecting all ages, ethnicities and both genders. Homelessness frequently evolves through a complex interaction of factors that are both internal and external to the individual themselves. Once homeless, equitable access to both preventative and remedial health care is lacking and is associated with a higher than average burden of cardiovascular disease [CVD] risk factors, morbidity and mortality and is accompanied by disproportionately high health care costs. The emergence of limited, small scale programs aimed at addressing the unique health and social needs of the homeless is encouraging. However, there has been inadequate commitment at the National, State or Provincial and local levels to implement policies and dedicate funding and resources to the expansion of such “individual level” interventions into comprehensive programs that deliver sustainable, integrated prevention and services, especially with regard to CVD. The long-term solutions that address the links between homelessness and CVD lie in preventing homelessness and reversing the trends in our health care system that create disparities for lower socioeconomic status [SES] and homeless individuals.

Abstract
BACKGROUND Coronary artery disease is the leading cause of death in women. We sought to validate previous clinical experience in which we have observed that elderly women with a very high left ventricular ejection fraction (LVEF) are at increased risk of death compared with elderly women with acute coronary syndromes with a normal LVEF. METHODS Data from 5,127 elderly female patients (age >65 years) enrolled in the Global Registry of Acute Coronary Events were collected. Patients were divided into 3 groups based on their LVEF: group I had a low ejection fraction (<55%), group II had a normal ejection fraction (55%-65%), and group III had a high ejection fraction (>65%). χ² test and multiple logistic regression analysis were performed. The main outcome measures were death in-hospital and death, stroke, rehospitalization, and myocardial infarction at 6-month follow-up. RESULTS Hospital mortality was 12% in group I. Patients in group III were more likely to die in-hospital than those in group II (P = .003). Multivariable logistic regression showed that high ejection fraction was an independent predictor of hospital death (odds ratio [OR] 2.5, 95% CI [CI] 1.2-5.2, P = .01), 6-month death (OR 2.0, 95% CI 1.1-3.4, P = .01), and cardiac arrest/ventricular fibrillation (OR 2.5, 95% CI 1.2-5.0, P = .01) compared with the normal ejection fraction group. CONCLUSIONS Having a very high LVEF (> 65%) is associated with worse survival and higher rates of sudden cardiac death than an LVEF considered to be in the reference range.

Abstract
BACKGROUND Blacks have higher rates of cardiovascular disease than whites. The age at which these differential rates emerge has not been fully examined. OBJECTIVE We examined cardiovascular disease prevalence and mortality among black and white adults across the adult age spectrum and explored potential mediators of these differential disease prevalence rates. METHODS We conducted a cross-sectional analysis of National Health and Nutrition Examination Survey data from 1999-2006. We estimated age-adjusted and age-specific prevalence ratios (PR) for cardiovascular disease (heart failure, stroke, or myocardial infarction) for blacks versus whites in adults aged 35 years and older and examined potential explanatory factors. From the National Compressed Mortality File 5-year aggregate file of 1999-2003, we determined age-specific cardiovascular disease mortality rates. RESULTS In young adulthood, cardiovascular disease prevalence was higher in blacks than whites (35-44 years PR 1.9; 95% confidence interval [CI], 1.1-3.4). The black-white PR decreased with each decade of advancing age (P for trend=.04), leading to a narrowing of the racial gap at older ages (65-74 years PR 1.2; 95% CI, 0.8-1.6; > or =75 years PR 1.0; 95% CI, 0.7-1.4). Clinical and socioeconomic factors mediated some, but not all, of the excess cardiovascular disease prevalence among young to middle-aged blacks. Over a quarter (28%) of all cardiovascular disease deaths among blacks occurred in those aged <65 years, compared with 13% among whites. CONCLUSIONS Reducing black/white disparities in cardiovascular disease will require a focus on young and middle-aged blacks.

Abstract
In medical clinic visits, patients do more than convey information about their symptoms and problems so doctors can diagnose and treat them. Patients may also show how they have made sense of their health problems and may press doctors to interpret their problems in certain ways. Using conversation analysis, we analyse a practice patients use early in the medical visit to show that relatively benign or commonplace interpretations of their symptoms are implausible. In this practice, which we term pre-emptive resistance, patients raise candidate explanations for their symptoms and then report circumstances that undermine these explanations. By raising candidate explanations on their own and providing evidence against them, patients call for doctors to restrict the range of diagnostic hypotheses they might otherwise consider. However, the practice does not compel doctors to transparently indicate whether they will do so. Patients also display their ability to recognise and weigh the evidence for common, easily remedied causes of their symptoms. By presenting evidence against them, they show doctors the relevance of more serious diagnostic interpretations without pressing for them outright.

Abstract
OBJECTIVES The objectives were to determine if an emergency department (ED) could improve the adherence to a door-to-electrocardiogram (ECG) time goal of 10 minutes or less for patients who presented to an ED with chest pain and the effect of this adherence on door-to-balloon (DTB) time for ST-segment elevation myocardial infarction (STEMI) cardiac catheterization (cath) alert patients. METHODS This was a planned 1-month before-and-after interventional study design for implementing a new process for obtaining ECGs in patients presenting to the study ED with chest pain. Prior to the change, patients were registered and triaged before an ECG was obtained. The new procedure required registration clerks to identify those with chest pain and directly overhead page or call a designated ECG technician. This technician had other ED duties, but prioritized performing ECGs and delivering them to attending physicians. A full registration process occurred after the clinical staff performed their initial assessment. The primary outcome was the total percentage of patients with chest pain who received an ECG within 10 minutes of ED arrival. The secondary outcome was DTB time for patients with STEMI who were emergently cath alerted. Data were analyzed using mean differences, 95% confidence intervals (CIs), and relative risk (RR) regression to adjust for possible confounders. RESULTS A total of 719 patients were studied: 313 before and 405 after the intervention. The mean (+/-standard deviation [SD]) age was 50 (+/-16) years, 54% were women, 57% were African American, and 36% were white. Patients walked in 89% of the time; 11% arrived by ambulance. Thirty-nine percent were triaged as emergent and 61% as nonemergent. Patients presented during daytime 68% of the time, and 32% presented during the night. Before the intervention, 16% received an ECG at 10 minutes or less. After the intervention, 64% met the time requirement, for a mean difference of 47.3% (95% CI = 40.8% to 53.3%, p < 0.0001). Results were not affected by age, sex, race, mode of arrival, triage classification, or time of arrival. For patients with STEMI cath alerts, four were seen before and seven after the intervention. No patients before the intervention had ECG time within 10 minutes, and one of four had DTB time of <90 minutes. After the intervention, all seven patients had ECG time within 10 minutes; the three arriving during weekday hours when the cath team was on site had DTB times of <90 minutes, but the four arriving at night and on weekends when the cath team was off site had DTB times of >90 minutes. CONCLUSIONS The overall percentage of patients with a door-to-ECG time within 10 minutes improved without increasing staffing. An ECG was performed within 10 minutes of arrival for all patients who were STEMI cath alerted, but DTB time under 90 minutes was achieved only when the cath team was on site.

Abstract
OBJECTIVE Previous studies show that the women with acute myocardial infarction (AMI) receive less fibrinolitic treatment than the men. The objective of this study is to analyze if it exists any difference in fibrinolysis related to gender and to compare the results with those obtained 10 years ago. DESIGN Retrospective descriptive study that compare patients with AMI of less than 24 hours of evolution of studies Analysis of Delay in Acute Infarct of Myocardium (ARIAM) in 2003-2004 and Project of Analysis Epidemiologist of Critical Patient (PAEEC) of 1992-1993. SETTING ICUs from 86 hospitals in Spain that participated in the PAEEC study and 120 ICUs in the ARIAM. PATIENTS We compared data of 9,981 patients including in study ARIAM in 2003-2004 with 1,668 of the PAEEC of 1992-1993. RESULTS Women were less likely to receive thrombolytic therapy than men (odds ratio= 0.82, p < 0.01), after adjusting for age, origin, size of the hospital and antecedents. The probability of fibrynolisis is lower in elderly, patients referred from the general ward, in hospitals of more than 1,000 beds and patients with arterial hypertension, stroke, diabetes or peripheral vascular disease. The probability of fibrinólisis is higher when patient is transferred from another hospital (followed by those of Emergencies Room), in the hospitals by less than 300 beds (followed by those of 300-1,000) and when history of prior ischemic heart disease exists. Comparing the two periods, has increased the frequency of fibrynolisis in both genders, although the increment has been greater in the women. CONCLUSIONS The women with AMI continue receiving less fibrynolisis, although exists an increase in the number of treatments superior to register in the men.

Abstract
BACKGROUND Cardiovascular diseases are the major cause of death in Bulgaria. Because of notable differences in mortality rates between Bulgaria and other European countries, we presume a tangible difference in the management of acute myocardial infarction (AMI) and an underutilization of evidence-based treatments. In order to determine the quality of care of patients with AMI in Bulgaria, we analyzed the appropriateness of current treatments and their relation to patient characteristics. METHODS We performed a descriptive cross-sectional study, using retrospectively collected data from medical charts. We included all patients with AMI, residing and admitted to hospitals in the region of Stara Zagora, Bulgaria, between September 1st and December 31st, 2004. Socioeconomic status was surveyed within the framework of a structured patient interview. We used chi-square tests with Fisher's exact probabilities to analyze the relationship between prehospital time delay age, sex, and socio-economic status of the patients and Student's independent samples t-tests to check hypotheses about means. RESULTS From 134 patients with AMI (mean age 64.6, SD 13.2, 66% male), 7% presented to a hospital within 59 minutes, and 44% within 4 hours of symptoms onset. The use of Heparin was 98%. In the first 24 hours, ASS was administrated in 82% and beta-Blockers in 73% of the cases. At discharge Aspirin, beta-Blockers, Angiotensin Converting Enzyme Inhibitors or AR-Blockers and Statins were used in 85%, 79%, 66%, and 43% of cases respectively. Intravenous fibrinolysis was applied in 32% of the eligible patients with ST-segment elevation. Percutaneous coronary interventions were applied in four patients within the first month after AMI. Hospital location in relation to a patient's place of residence and manner of transportation to hospital did not influence the time delay between the onset of symptoms to the start of hospital treatment. In the study region, a relation between time delay and both age and education level was observed. CONCLUSION The actual quality of care of patients with AMI in Bulgaria lies far from the evidence-based recommendations. Additional research and improvements in health services are needed to reduce the burden of cardiovascular disease in Bulgaria.

Abstract
Prior studies have suggested gender-based differences in the care of elderly patients with acute medical conditions such as myocardial infarction and stroke, but it is unknown whether these differences are seen in the care of abdominal pain. The objective of this study was to examine differences in evaluation, management, and diagnoses between elderly men and women presenting to the Emergency Department (ED) with abdominal pain. For this observational cohort study, a chart review was conducted of consecutive patients aged 70 years or older presenting with a chief complaint of abdominal pain. Primary outcomes were care processes (e.g., receipt of pain medications, imaging) and clinical outcomes (e.g., hospitalization, etiology of pain, and mortality). Of 131 patients evaluated, 60% were women. Groups were similar in age, ethnicity, insurance status, and predicted mortality. Men and women did not differ in the frequency of medical (56% vs. 57%, respectively), surgical (25% vs. 18%, respectively), or non-specific abdominal pain (19% vs. 25%, respectively, p = 0.52) diagnoses. Similar proportions underwent abdominal imaging (62% vs. 68%, respectively, p = 0.42), received antibiotics (29% vs. 30%, respectively, p = 0.85), and opiates for pain (35% vs. 41%, respectively, p = 0.50). Men had a higher rate of death within 3 months of the visit (19% vs. 1%, respectively, p < 0.001). Unlike prior research in younger patients with abdominal pain and among elders with other acute conditions, we noted no difference in management and diagnoses between older men and women who presented with abdominal pain. Despite a similar predicted mortality and ED evaluation, men had a higher rate of death within 3 months.

Abstract
Strong evidence supports the existence of a social gradient in poor prognosis in patients with coronary heart disease (CHD). However, knowledge regarding what factors may explain this relationship is limited. We aimed to analyze in women CHD patients the association between personal income and recurrent events and to determine whether lifestyle, biological and psychosocial factors contribute to the explanation of this relationship. Altogether 188 women hospitalized for a cardiac event were assessed for personal income, demographic factors, lipids, inflammatory markers, cortisol, creatinine, lifestyle and psychosocial factors, i.e. alcohol consumption, smoking habits, body-mass index, depressive symptoms, anxiety, vital exhaustion, availability of social interaction, hostility and anger-related characteristics and were followed for cardiovascular death and recurrent acute myocardial infarction (AMI). During the 6-year follow-up 18 patients deceased and 31 experienced cardiovascular death or non-fatal AMI. After adjustment for confounders, patients with medium and high income had lower risk for recurrent events relative to those with low income (HR (95% CI): 0.38 (0.15-0.97) and 0.39 (0.17-0.93), respectively). Controlling for smoking reduced by 12.8% the risk for recurrent events associated with high versus low income, while adjusting for depression decreased the risk for middle versus low income by 13.5%. Anger symptoms explained 16.7% of the risk for recurrent events associated with middle versus low income and 10.2% of the risk for high versus low income. We suggest that in women with CHD low income is associated with recurrent events and that smoking, depressive symptomatology and anger symptoms may contribute to the explanation of this relationship.

Abstract
OBJECTIVE To evaluate the association of neighborhood-level income and individual-level education with post-myocardial infarction (MI) mortality in community patients. PARTICIPANTS AND METHODS From November 1, 2002, through May 31, 2006, 705 (mean+/-SD age, 69+/-15 years; 44% women) residents of Olmsted County, MN, who experienced an MI meeting standardized criteria were prospectively enrolled and followed up. The neighborhood's median household income was estimated by census tract data; education was self-reported. Demographic and clinical variables were obtained from the medical records. RESULTS Living in a less affluent neighborhood and having a low educational level were both associated with older age and more comorbidity. During follow-up (median, 13 months), 155 patients died. Neighborhood income (hazard ratio [HR], 2.10; 95% confidence interval [CI], 1.42-3.12; for lowest [median, $34,205] vs highest [median, $60,652] tertile) and individual education (HR, 2.21; 95% CI, 1.47-3.32; for <12 vs >12 years) were independently associated with mortality risk. Adjustment for demographics and various post-MI prognostic indicators attenuated these estimates, yet excess risk persisted for low neighborhood income (HR, 1.62; 95% CI, 1.08-2.45). Modeled as a continuous variable, each $10,000 increase in annual income was associated with a 10% reduction in mortality risk (adjusted HR, 0.90; 95% CI, 0.82-0.99). CONCLUSION In this geographically defined cohort of patients with MI, low individual education and poor neighborhood income were associated with a worse clinical presentation. Poor neighborhood income was a powerful predictor of mortality even after controlling for a variety of potential confounding factors. These data confirm the socioeconomic disparities in health after MI.

Abstract
PURPOSE Gender and age differences in medical care are well documented. We examined age and gender differences in Medicare expenditures for lung cancer decedents in the last year of life (LYOL) through a cross-sectional study of Medicare administrative and claims data. METHODS Participants were aged Medicare beneficiaries (>or=68) with lung cancer, who were covered by Parts A and B for 36 months before death (1996-1999; n = 13,120). Regression techniques were used to estimate age and gender differences in mean Medicare utilization and expenditures in the LYOL overall and by type of service, conditional on use: inpatient, outpatient, physician, skilled nursing facility (SNF), home health, and hospice, controlling for demographic, clinical, geographic, and supply characteristics. RESULTS Women were more likely than men to use inpatient, SNF, home health, and hospice services. Women's average expenditures were approximately dollars 1,900 greater than men's, with differences attributed to higher average expenditures for SNF, home health, and hospice. Older cohorts used fewer inpatient and outpatient services and used more SNF and hospice services in their LYOL. Average Medicare expenditures were significantly lower in older cohorts (dollars 8,487 less for those age >or=85 at death than for those 68-74). Adjusting for age explains most of the gender differences in average Medicare expenditures. Remaining gender differences vary across age cohorts, with larger gender differences in social-supportive service expenditures among those 68-74 and 75-84 and outpatient and physician services among those 75-84 and >or=85. DISCUSSION AND CONCLUSIONS Our findings suggest that gender disparities in expenditures are generally small at the end of life for lung cancer decedents, particularly among the older cohorts. As expected, the bigger observed differences are by age although the direction of the association is not consistent across types of service. Higher expenditures for women on social-supportive services may reflect fewer informal supports for older women compared with men.

Abstract
BACKGROUND AND OBJECTIVE The establishment of national guidelines is one approach to creating equity in terms of access to care, and both internationally and in Sweden, guidelines have been developed for coronary heart disease. We have analysed drug treatment in Sweden according to national guidelines after acute myocardial infarction (AMI). The aim was to investigate whether there are differences between population groups according to sex, education, country of birth and diabetes. METHODS Information was obtained from the Swedish Prescribed Drug Register on drugs dispensed between July and October 2005 for incident cases of AMI during the period 2003-2004 (n=28,168). Data on socio-economic and demographic conditions were included. Dispensed drugs after AMI were compared to the recommended drug treatment according to Swedish and European guidelines--acetylsalicylic acid (ASA), beta-blockers, lipid-lowering drugs and angiotensin-converting enzyme inhibitors (ACE inhibitors). RESULTS We found that, in general, there were only small differences between the sexes and between educational groups. The greatest differences were found in comparisons between regions of birth. In particular, foreign-born patients resident in Sweden but originally from outside the EU25 countries used fewer drugs than Swedish-born patients. The OR (odds ratio) for ASA was 0.73 [95% confidence interval (CI) 0.63-0.85], for beta-blockers, 0.72 (0.63-0.83), for lipid-lowering drugs, 0.75 (0.65-0.86) and for ACE inhibitors, 0.76 (0.67-0.86). CONCLUSIONS In general, we found only slight differences--or none at all--between population groups in terms of drug treatment after AMI. Only among immigrants from outside the EU25 countries was there a tendency towards a lesser use of the recommended drugs according to the national guidelines.

Abstract
BACKGROUND Previous studies examining sex-related differences in the treatment of coronary artery disease have focused on patients in hospital. We sought to examine sex-related differences at an earlier point in care--presentation to the emergency department. METHODS We collected data on ambulatory care and hospital admissions for 54,134 patients (44% women) who presented to an emergency department in Alberta between July 1998 and March 2001 because of acute myocardial infarction, unstable angina, stable angina or chest pain. We used logistic regression and Cox regression analyses to determine sex-specific associations between the likelihood of discharge from the emergency department or coronary revascularization within 1 year and 1-year mortality after adjusting for age, comorbidities and socioeconomic factors. RESULTS Following the emergency department visit, 91.3% of patients with acute myocardial infarction, 87.4% of those with unstable angina, 40.7% of those with stable angina and 19.8% of those with chest pain were admitted to hospital. Women were more likely than men to be discharged from the emergency department: adjusted odds ratio (and 95% confidence interval [CI]) 2.25 (1.75-2.90) for acute myocardial infarction, 1.71 (1.45-2.01) for unstable angina, 1.33 (1.15-1.53) for stable angina and 1.46 (1.36-1.57) for chest pain. Women were less likely than men to undergo coronary revascularization within 1 year: adjusted odds ratio (and 95% CI) 0.65 (0.57-0.73) for myocardial infarction, 0.39 (0.35-0.44) for unstable angina, 0.35 (0.29-0.42) for stable angina and 0.32 (0.27-0.37) for chest pain. Female sex had no impact on 1-year mortality among patients with acute myocardial infarction; it was associated with a decreased 1-year mortality among patients with unstable angina, stable angina and chest pain: adjusted hazard ratio (and 95% CI) 0.60 (0.46-0.78), 0.60 (0.46-0.78) and 0.74 (0.63-0.87) respectively. INTERPRETATION Women presenting to the emergency department with coronary syndromes are less likely than men to be admitted to an acute care hospital and to receive coronary revascularization procedures. These differences do not translate into worse outcomes for women in terms of 1-year mortality.
