Abstract
OBJECTIVE Case-fatality rates (CFRs) for myocardial infarction (MI) and ischaemic stroke (IS) have decreased over time due to better prevention, medication and hospital care. It is unclear whether these improvements have been equally distributed according to socioeconomic position (SEP) and sex. The aim of this study is to analyse differences in short-term and long-term CFR for MI and IS by SEP and sex between the periods 1990-1994 to 2005-2009 for the entire Swedish population. DESIGN Population-based cohort study based on Swedish national registers. METHODS We used logistic regression and flexible parametric models to estimate short-term CFR (death before reaching the hospital or on the disease event day) and long-term CFR (1 year case-fatality conditional on surviving short-term) across five distinct SEP groups, as well as CFR differences (CFRDs) between SEP groups for both MI and IS from 1990-1994 to 2005-2009. : Result S: Overall short-term CFR for both MI and IS decreased between study periods. For MI, differences in short-term and long-term CFR between the least and most favourable SEP group were generally stable, except in long-term CFR among women; intermediate SEP groups mostly managed to catch up with the most favourable SEP group. For IS, short-term CFRD generally decreased compared with the most favourable group; but long-term CFRD were mostly stable, except for an increase for older subjects. CONCLUSION Despite a general decline in CFR for MI and IS across all SEP groups and both sexes as well as some reductions in CFRD, we found persistent and even increasing CFRD among the least advantaged SEP groups, older patients and women. We speculate that targeted prevention rather than treatment strategies have the potential to reduce these inequalities.

Abstract
BACKGROUND Lower socioeconomic position (SEP) is associated with an increased risk of myocardial infarction (MI) incidence and mortality, but the relative importance of different socioeconomic resources at different stages of the disease remains unclear. METHODS A nationally representative register-based sample of 40- to 60-year-old Finnish men and women in 1995 (n= 302 885) were followed up for MI incidence and mortality in 1996-2007. We compared the effects of education, occupation, income and wealth on first MI incidence, first-day and long-term fatality. Cox's proportional hazards regression and logistic regression models were estimated adjusting for SEP covariates simultaneously to assess independent effects. RESULTS Fully adjusted models showed greatest relative inequalities of MI incidence by wealth in both sexes, with an increased risk also associated with manual occupations. Education was a significant predictor of incidence in men. Low income was associated with a greater risk of death on the day of MI incidence [odds ratio (OR) = 1.40 in men and 1.95 in women when comparing lowest and highest income quintiles], and in men, with long-term fatality [hazard ratio (HR) = 1.74]. Wealth contributed to inequalities in first-day fatality in men and in long-term fatality in both sexes. CONCLUSION The results show that different socioeconomic resources have diverse effects on the disease process and add new evidence on the significant association of wealth with heart disease onset and fatality. Targeting those with the least resources could improve survival in MI patients and help reduce social inequalities in coronary heart disease mortality.

Abstract
Background Patients with low socioeconomic position have higher rates of mortality after diagnosis of acute coronary syndrome (ACS), but little is known about the mechanisms behind this social inequality. The aim of the present study was to examine whether any educational inequality in survival after ACS was influenced by comorbid conditions including depression. Methods From 2001 to 2009 all first-time ACS patients were identified in the Danish National Patient Registry. This cohort of 83 062 ACS patients and a matched reference population were followed for incident depression and mortality until December 2012 by linkage to person, patients and prescription registries. Educational status was defined at study entry and the impact of potential confounders and mediators (age, gender, cohabitation status, somatic comorbidity and depression) on the relation between education and mortality were identified by drawing a directed acyclic graph and analysed using multiple Cox regression analyses. Findings During follow-up, 29 583(35.6%) of ACS patients and 19 105(22.9%) of the reference population died. Cox regression analyses showed an increased mortality in the lowest educated compared to those with high education in both ACS patients and the reference population. Adjustment for previous and incident depression or other covariables only attenuated the relations slightly. This pattern of associations was seen for mortality after 30 days, 1 year and during total follow-up. Conclusion In this study the relative excess mortality rate in lower educated ACS patients was comparable with the excess risk associated with low education in the background population. This educational inequality in survival remained after adjustment for somatic comorbidity and depression.

Abstract
INTRODUCTION Previous studies have established a relationship between socioeconomic status (SES) and survival in coronary heart disease. Acute cardiac care in Sweden is considered to be excellent and independent of SES. We studied the influence of area-level socioeconomic status on mortality after hospitalization for acute myocardial infarction (AMI) between 1995 and 2013 in the Gothenburg metropolitan area, which has little over 800,000 inhabitants and includes three city hospitals. METHODS Data were obtained from the SWEDEHEART registry (Swedish Websystem for Enhancement of Evidence-Based Care in Heart Disease Evaluated According to Recommended Therapies) and the Swedish Central Bureau of Statistics for patients hospitalized for ST-elevation myocardial infarction (STEMI) and non-STEMI in the city of Gothenburg in Western Sweden. The groups were compared using Cox proportional hazards regression and logistic regression. RESULTS 10,895 (36% female) patients were hospitalized due to AMI during the study period. Patients residing in areas with lower SES had higher rates of smoking and diabetes (P<0.001), and were also at increased risk of developing complications, including heart failure and cardiogenic shock (P<0.05). Living in an area with lower SES associated with increased risk of dying after an AMI also in models adjusted for risk factors (P<0.05). CONCLUSION Also in a country with strong egalitarian traditions, lower SES associates with worse prognosis after AMI, an association that persists after adjustments for differences in traditional cardiovascular risk factors.

Case fatality of myocardial infarction among shift workers. Int Arch Occup Environ Health 2014; 88:599-605.

Abstract
PURPOSE Shift work has been associated with an excess risk of cardiovascular disease (CVD) and more specifically myocardial infarction (MI). The majority of the studies that found a positive association between shift work and CVD have been based on incidence data. The results from studies on cardiovascular-related mortality among shift workers have shown little or no elevated mortality associated with shift work. None of the previous studies have analysed short-term mortality (case fatality) after MI. Therefore, we investigated whether shift work is associated with increased case fatality after MI compared with day workers. METHODS Data on incident cases with first MI were obtained from case-control study conducted in two geographical sites in Sweden (Stockholm Heart Epidemiology Program and Västernorrland Heart Epidemiology Program), including 1,542 cases (1,147 men and 395 women) of MI with complete working time information and 65 years or younger. Case fatality was defined as death within 28 days of onset of MI. Risk estimates were calculated using logistic regression. RESULTS The crude odds ratios for case fatality among male shift workers were 1.63 [95 % confidence interval (CI) 1.12, 2.38] and 0.56 (95 % CI 0.26, 1.18) for female shift workers compared with day workers. Adjustments for established cardiovascular risk factors such as diabetes type II and socio-economic status did not alter the results. CONCLUSION Shift work was associated with increased risk of case fatality among male shift workers after the first MI.

Abstract
Background Socioeconomic disparities in survival after acute myocardial infarction (AMI) have been found in many countries. However, population-based results from Germany are lacking so far. Thus, the objective of this study was to examine the association between educational status and long-term mortality in a population-based sample of people with AMI. Methods The sample consisted of 2,575 men and 844 women, aged 28–74 years, hospitalized with a first-time AMI between 1 January 2000 and 31 December 2008, recruited from a population-based AMI registry. Patients were followed up until December 2011. Data on education, risk factors and co-morbidities were collected by individual interviews; data on clinical characteristics and AMI treatment by chart review. Cox proportional hazards models were used to assess the relationship between educational status and long-term mortality. Results During follow-up, 19.1% of the patients with poor education died compared with 13.1% with higher education. After adjustment for covariates, no effect of education on mortality was found for the total sample and for patients aged below 65 years. In older people, however, low education level was significantly associated with increased mortality (hazard ratio (HR) 1.44, 95% confidence interval (CI) 1.05–1.98, p = 0.023). Stratified analyses showed that women older than 64 years with poor education were significantly more likely to die than women in the same age group with higher education (HR 1.57, 95% CI 1.02–2.41, p = 0.039). Conclusions Elderly, poorly educated patients with AMI, and particularly women, have poorer long-term survival than their better educated peers. Further research is required to illuminate the reasons for this finding.

Abstract
While the risk for arterial vascular disease has been shown to be influenced by socioeconomic status (SES), there is limited information whether SES also influences the risk for venous thromboembolism (VTE). To evaluate whether there is an association between SES and VTE incidence. In 1990, all 730,050 inhabitants (379,465 women and 350,585 men) above 25 years of age in the County of Skåne in Sweden were evaluated with regard to age, household income, marital status, country of birth, number of years of residence in Sweden, educational level, and concomitant diseases. The cohort was hereafter prospectively investigated regarding diagnosis of, or death from VTE (deep venous thrombosis or pulmonary embolism ), during 1991-2003. The association between socioeconomic data and concomitant diseases at the baseline investigation 1990 and incidence of VTE during follow-up was examined by Cox proportional hazard models. During the 13 years prospective follow-up, 10,212 women and 7,922 men were diagnosed with VTE. In both genders, age above 40 years at baseline, low income, single status, and a lower level of education were associated with an increased risk of VTE. However, both men and women born outside of Sweden have a lower risk for VTE during follow-up, however. Age above 40 years, low income, single marital status, and lower level of education were independently related to an increased risk of VTE diagnosis during 13 years of prospective follow-up.

Abstract
Aims: In western countries out-of-hospital ischaemic heart disease (IHD) deaths account for approximately 50–70% of all IHD deaths. The objective was to examine the trends in out-of-hospital IHD deaths in the Region of Skåne in southern Sweden, in different sex- and age-groups. Methods: All 14,347 persons (range 24–110 years) in Skåne who died out-of-hospital between 1992 and 2003 from IHD (I410–I414; I20–I25) as the underlying cause of death. Subjects with previous admission for IHD since 1970 were excluded. Data were retrieved from the Swedish National Cause of Death and Patient Register. Age-standardized IHD mortality rates and trends were calculated using Poisson regression analysis. Results: Age-standardized annual out-of-hospital IHD mortality rates from 1992–2003 decreased in men from 177±13 to 103±9/100,000 inhabitants (−4.7%; p<0.001) and in women from 142±11 to 96±9/100,000 (−2.7%; p<0.001). In men, the annual change in age-standardized IHD mortality rates were −5.3 % ( p<0.001), −4.0 % ( p<0.001) and −4.7 % ( p<0.001), respectively, in the age groups 20–64 years, 65–74 years and ≥75 years. Corresponding figures in women were −4.4 % ( p<0.001), −2.4 % ( p=0.003) and −2.5 % ( p<0.001). The proportion of IHD deaths occurring out-of-hospital was in these age groups 50%, 40% and 35% respectively. Conclusions: In Skåne, out-of-hospital mortality in IHD deaths decreased significantly between 1992 and 2003. The decrease is more pronounced in men than women, and at the end of the study period in 2003, rates were almost equal. The proportion of IHD deaths occurring outside hospital was higher in younger people than in older people.

The relation between socioeconomic status and short-term mortality after acute myocardial infarction persists in the elderly: results from a nationwide study. Eur J Epidemiol 2012; 27:605-13.

Abstract
We assessed whether the previously observed relationship between socioeconomic status (SES) and short-term mortality (pre-hospital mortality and 28-day case-fatality) after a first acute myocardial infarction (AMI) in persons <75 years, are also observed in the elderly (i.e. ≥75 years), and whether these relationships vary by sex. A nationwide register based cohort study was conducted. Between January 1st 1998 and December 31st 2007, 76,351 first AMI patients were identified, of whom 60,498 (79.2 %) were hospitalized. Logistic regression analyses were performed to measure SES differences in pre-hospital mortality after a first AMI and 28-day case-fatality after a first AMI hospitalization. All analyses were stratified by sex and age group (<55, 55–64, 65–74, 75–84, ≥85), and adjusted for age, ethnic origin, marital status, and degree of urbanization. There was an inverse relation between SES and pre-hospital mortality in both sexes. There was also an inverse relation between SES and 28-day case-fatality after hospitalization, but only in men. Compared to elderly men with the highest SES, elderly men with the lowest SES had a higher pre-hospital mortality in both 75–84 year-olds (OR = 1.26; 95 % CI 1.09–1.47) and ≥85 year-olds (OR = 1.26; 1.00–1.58), and a higher 28-day case-fatality in both 75–84 year-olds (OR = 1.26; 1.06–1.50) and ≥85 year-olds (OR = 1.36; 0.99–1.85). Compared to elderly women with the highest SES, elderly women with the lowest SES had a higher pre-hospital mortality in ≥85 year-olds (OR = 1.20; 0.99–1.46). To conclude, in men there are SES inequalities in both pre-hospital mortality and case-fatality after a first AMI, in women these SES inequalities are only shown in pre-hospital mortality. The inequalities persist in the elderly (≥75 years of age). Clinicians and policymakers need to be more vigilant on the population with a low SES background, including the elderly.

Abstract
BACKGROUND During the first year after a cardiac event, many patients are offered participation in a cardiac rehabilitation programme, after which the patients are often not given the opportunity to continue to attend rehabilitation and secondary prevention programmes. AIM This study describes the primary health care centres' (PHCC) resources regarding cardiac rehabilitation/secondary prevention programmes for coronary heart disease (CHD) patients in a southern Swedish region. METHOD A questionnaire containing 26 dichotomous or multiple choice questions was sent to the responsible manager of all 137 public and private PHCCs in Region Skåne. Questionnaires from 91 (66%) of the PHCCs were completed and returned. RESULT Few nurses at the PHCCs had special training regarding CHD (10%), cardiac rehabilitation (8%) or heart failure (32%). Twenty-one per cent of the physicians had special training regarding CHD. One third of the PHCCs did not offer long-term secondary prevention programmes, and few (6%) had any routines for offering socio-economic support to CHD patients. Comparison of private and public PHCCs showed that the private centres could not offer a physiotherapist (61 vs. 84%) or dietician (32 vs. 73%; p = 0.03) to the same extension as the public ones. Furthermore, the majority (91%) of PHCCs had no cooperation with patient organizations. CONCLUSIONS The PHCCs need to improve the strategies and long-term rehabilitation programmes. Furthermore, they need to focus on education programme for the staff. The result revealed that the PHCCs lack resources, strategies and long-term care programmes for CHD patients.

Abstract
BACKGROUND Socioeconomic, demographic, and geographic factors are known determinants of stroke and myocardial infarction (MI) risk. Clustering of these factors in neighborhoods needs to be taken into consideration during planning, prioritization and implementation of health programs intended to reduce disparities. Given the complex and multidimensional nature of these factors, multivariate methods are needed to identify neighborhood clusters of these determinants so as to better understand the unique neighborhood profiles. This information is critical for evidence-based health planning and service provision. Therefore, this study used a robust multivariate approach to classify neighborhoods and identify their socio-demographic characteristics so as to provide information for evidence-based neighborhood health planning for stroke and MI. METHODS AND FINDINGS The study was performed in East Tennessee Appalachia, an area with one of the highest stroke and MI risks in USA. Robust principal component analysis was performed on neighborhood (census tract) socioeconomic and demographic characteristics, obtained from the US Census, to reduce the dimensionality and influence of outliers in the data. Fuzzy cluster analysis was used to classify neighborhoods into Peer Neighborhoods (PNs) based on their socioeconomic and demographic characteristics. Nearest neighbor discriminant analysis and decision trees were used to validate PNs and determine the characteristics important for discrimination. Stroke and MI mortality risks were compared across PNs. Four distinct PNs were identified and their unique characteristics and potential health needs described. The highest risk of stroke and MI mortality tended to occur in less affluent PNs located in urban areas, while the suburban most affluent PNs had the lowest risk. CONCLUSIONS Implementation of this multivariate strategy provides health planners useful information to better understand and effectively plan for the unique neighborhood health needs and is important in guiding resource allocation, service provision, and policy decisions to address neighborhood health disparities and improve population health.

Abstract
To explore the relation between country of birth and risk of hospitalization due to heart failure (HF). All 40-89 year-old inhabitants in the city of Malmö, Sweden (n = 114,917, of whom 15.2% were born outside Sweden) were followed from November 1st, 1990 until December 31st, 2007. During a mean follow-up of 13.5 ± 5.3 years, a total of 7,640 individuals (47.4% men) were discharged from hospital with first-ever HF as primary diagnosis. Of them, 1,243 individuals had myocardial infarction (MI) before or concurrent with the HF hospitalization. The risk of HF was compared between immigrants from selected countries and Swedish natives. The overall analysis showed substantial differences among immigrant groups (P < 0.001). Compared to Swedish natives, significantly increased HF risk was found among immigrants from Finland (HR (hazard ratio): 1.40; 95% CI, 1.10-1.81), Former Yugoslavia (1.45: 1.23-1.72) and Hungary (1.48: 1.16-1.89), taking age, sex, marital status, annual income and housing condition into account. Analysis results were similar when cases with MI before or concurrent with the HF hospitalization were included in the analysis. In general, the risk of HF was significantly higher among immigrants from high-income and middle-income countries. Marital status, annual income and housing condition were also significant independent risk factors for HF in this population. There are substantial differences in risk of hospitalization due to HF among immigrants from different countries that can not be explained by socioeconomic factors. To what extent these differences could be explained by biological risk factors remains to be explored.

Gerward S, Tydén P, Engström G, Hedblad B. Marital status and occupation in relation to short-term case fatality after a first coronary event--a population based cohort. BMC Public Health 2010; 10:235. [PMID: 20459706 PMCID: PMC2874781 DOI: 10.1186/1471-2458-10-235] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2009] [Accepted: 05/10/2010] [Indexed: 11/13/2022] Open
Abstract
Background Although marital status and low occupation level has been associated with mortality, the relationship with case fatality rates (CFR) after a coronary event (CE) is unclear. This study explored whether incidence of CE and short-term CFR differ between groups defined in terms of marital status and occupation, and if this could be explained by biological and life-style risk factors. Methods Population-based cohort study of 33,224 subjects (67% men), aged 27 to 61 years, without history of myocardial infarction, who were enrolled between 1974 and 1992. Incidence of CE, and CFR (death during the first day or within 28 days after CE, including out-of-hospital deaths) was examined over a mean follow-up of 21 years. Results A total of 3,035 men (6.0 per 1000 person-years) and 507 women (2.4 per 1000) suffered a first CE during follow-up. CFR (during the 1st day) was 29% in men and 23% in women. After risk factor adjustments, unmarried status in men, but not in women, was significantly associated with increased risk of suffering a CE [hazard ratios (HR) 1.10, 95% CI: 0.97-1.24; 1.42: 1.27-1.58 and 1.77: 1.31-2.40 for never married, divorced and widowed, respectively, compared to married]. Unmarried status, in both gender, was also related with an increased CFR (1st day), taking potential confounders into account (odds ratio (OR) 2.14, 95% CI: 1.63-2.81; 1.91: 1.50-2.43 and 1.49: 0.77-2.89 for never married, divorced and widowed, respectively, compared to married men. Corresponding figures for women was 2.32: 0.93-5.81; 1.87: 1.04-3.36 and 2.74: 1.03-7.28. No differences in CFR (1st day) were observed between occupational groups in neither gender. Conclusions In this population-based Swedish cohort, short-term CFR was significantly related to unmarried status in men and women. This relationship was not explained by biological-, life-style factors or occupational level.
