Patient-level comparison of heart failure patients in clinical phenotype and prognosis from China and Sweden.

BACKGROUND: Clinical phenotype and prognosis of heart failure (HF) may be variable among different racial populations. Therefore, a patient-level comparison of hospitalized HF patients in two university hospitals from China and Sweden was performed. METHODS AND RESULTS: This study was a pooled data analysis of the patients prospectively enrolled in two single-center studies in China (n = 949) and Sweden (n = 1639) from 2011 to 2015. Clinical characteristics and 6-month all-cause mortality were collected. Higher systolic blood pressure (126.1 ± 20.3 vs. 114.2 ± 15.4 mmHg, p < 0.001) and NT-proBNP level (4540 vs. 3251 pg/mL, p = 0.013) were found in the Swedish cohort, also more patients with ischemic heart disease (32.0% vs. 19.2%), hypertension (64.2% vs. 36.8%), valvular heart disease (40.9% vs.31.6%) and atrial fibrillation (55.3% vs. 39.6%) (all p < 0.001). The use of ACEIs/ARBs (48.8% vs. 80.8%) or beta-blockers (58.8% vs. 86.5%) (both p < 0.001) was lower in Chinese cohort. Given younger age in Chinese cohort (61.6 vs. 76.4 years, p < 0.001), age-stratified analyses were conducted, as there were similar patient numbers in 50-74 years in Chinese (n = 550) and Swedish (n = 554) cohorts, therefore baseline characteristics and prognosis were further compared. The age- and sex-adjusted outcome (HR 0.80 [95% CI 0.55-1.19], p = 0.273) was comparable between the two populations. The NT-proBNP and eGFR independently predicted 6-month mortality in both Chinese (HR [95% CI] 1.006 [1.003-1.008], 0.986 [0.976-0.999]) and Swedish cohort (1.003 [1.000-1.007], 0.988 [0.976-0.999]). CONCLUSIONS: Patient-level comparison of real-world HF populations from China and Sweden demonstrated different clinical phenotypes and therapy but similar prognosis and their predictors.

Body Mass Index in Young Women and Risk of Cardiomyopathy: A Long-Term Follow-Up Study in Sweden.

BACKGROUND: Incidence rates of cardiomyopathies, which are a common cause of heart failure in young people, have increased during the last decades. An association between body weight in adolescence and future cardiomyopathy among men was recently identified. Whether or not this holds true also for women is unknown. The aim was therefore to determine whether for young women being overweight or obese is associated with a higher risk of developing cardiomyopathy. METHODS: This was a registry-based national prospective cohort study with data collected from the Swedish Medical Birth Register, 1982 to 2014, with up to 33 years of follow-up. Included women were of childbearing age (18-45 years) during the initial antenatal visit in their first or second pregnancy (n=1 393 346). We obtained baseline data on body mass index (BMI), smoking, education, and previous disorders. After exclusions, mainly because of previous disorders, the final sample was composed of 1 388 571 women. Cardiomyopathy cases were identified by linking the Medical Birth Register to the National Patient and Cause of Death registers. RESULTS: In total, we identified 1699 cases of cardiomyopathy (mean age at diagnosis, 46.2 [SD 9.1] years) during the follow-up with an incidence rate of 5.9 per 100 000 observation years. Of these, 481 were diagnosed with dilated cardiomyopathy, 246 had hypertrophic cardiomyopathy, 61 had alcohol/drug-induced cardiomyopathy, and 509 had other forms. The lowest risk for being diagnosed with a cardiomyopathy was detected at a BMI of 21 kg/m2, with a gradual increase in risk with higher BMI, particularly for dilated cardiomyopathy, where a hazard ratio of 4.71 (95% CI, 2.81-7.89) was found for severely obese subjects (BMI ≥35 kg/m2), as compared with BMI 20 to <22.5. CONCLUSIONS: Elevated BMI among young women was associated with an increased risk of being diagnosed with a subsequent cardiomyopathy, especially dilated cardiomyopathy, starting already at mildly elevated body weight, whereas severe obesity entailed an almost 5-fold increase in risk. With the increasing numbers of persons who are overweight or obese, higher rates of cardiomyopathy can be expected in the future, along with an altered disease burden related to adiposity.

Clinical presentation, management, and 6-month outcomes in women with peripartum cardiomyopathy: an ESC EORP registry.

AIMS: We sought to describe the clinical presentation, management, and 6-month outcomes in women with peripartum cardiomyopathy (PPCM) globally. METHODS AND RESULTS: In 2011, >100 national and affiliated member cardiac societies of the European Society of Cardiology (ESC) were contacted to contribute to a global registry on PPCM, under the auspices of the ESC EURObservational Research Programme. These societies were tasked with identifying centres who could participate in this registry. In low-income countries, e.g. Mozambique or Burkina Faso, where there are no national societies due to a shortage of cardiologists, we identified potential participants through abstracts and publications and encouraged participation into the study. Seven hundred and thirty-nine women were enrolled in 49 countries in Europe (33%), Africa (29%), Asia-Pacific (15%), and the Middle East (22%). Mean age was 31 ± 6 years, mean left ventricular ejection fraction (LVEF) was 31 ± 10%, and 10% had a previous pregnancy complicated by PPCM. Symptom-onset occurred most often within 1 month of delivery (44%). At diagnosis, 67% of patients had severe (NYHA III/IV) symptoms and 67% had a LVEF ≤35%. Fifteen percent received bromocriptine with significant regional variation (Europe 15%, Africa 26%, Asia-Pacific 8%, the Middle East 4%, P < 0.001). Follow-up was available for 598 (81%) women. Six-month mortality was 6% overall, lowest in Europe (4%), and highest in the Middle East (10%). Most deaths were due to heart failure (42%) or sudden (30%). Re-admission for any reason occurred in 10% (with just over half of these for heart failure) and thromboembolic events in 7%. Myocardial recovery (LVEF > 50%) occurred only in 46%, most commonly in Asia-Pacific (62%), and least commonly in the Middle East (25%). Neonatal death occurred in 5% with marked regional variation (Europe 2%, the Middle East 9%). CONCLUSION: Peripartum cardiomyopathy is a global disease, but clinical presentation and outcomes vary by region. Just under half of women experience myocardial recovery. Peripartum cardiomyopathy is a disease with substantial maternal and neonatal morbidity and mortality.

Higher Body Mass Index in Adolescence Predicts Cardiomyopathy Risk in Midlife.

BACKGROUND: Modifiable lifestyle factors in relation to risk for cardiomyopathy, a common and increasing cause of heart failure in the young, have not been widely studied. We sought to investigate a potential link between obesity, a recognized predictor of early heart failure, in adolescence and being diagnosed with cardiomyopathy in adulthood. METHODS: This was a nationwide register-based prospective cohort study of 1 668 893 adolescent men (mean age, 18.3 years; SD, 0.7 years) who enlisted for compulsory military service from 1969 to 2005. At baseline, body mass index (BMI), blood pressure, and medical disorders were registered, along with test results for fitness and muscle strength. Cardiomyopathy diagnoses were identified from the National Hospital Register and Cause of Death Register during an up to 46-year follow-up and divided into categories: dilated, hypertrophic, alcohol/drug-induced, and other. Hazard ratios were calculated with Cox proportional hazards models. RESULTS: During follow-up (median, 27 years; Q1-Q3, 19-35 years), 4477 cases of cardiomyopathy were identified, of which 2631 (59%) were dilated, 673 (15%) were hypertrophic, and 480 (11%) were alcohol/drug-induced. Increasing BMI was strongly associated with elevated risk of cardiomyopathy, especially dilated, starting at levels considered normal (BMI, 22.5-<25 kg/m2; hazard ratio, 1.38 [95% CI, 1.22-1.57]), adjusted for age, year, center, and baseline comorbidities, and with a >8-fold increased risk at BMI ≥35 kg/m2 compared with BMI of 18.5 to <20 kg/m2. For each 1-unit increase in BMI, similarly adjusted hazard ratios were 1.15 (95% CI, 1.14-1.17) for dilated cardiomyopathy, 1.09 (95% CI, 1.06-1.12) for hypertrophic cardiomyopathy, and 1.10 (1.06-1.13) for alcohol/drug-induced cardiomyopathy. CONCLUSIONS: Even mildly elevated body weight in late adolescence may contribute to being diagnosed with cardiomyopathy in adulthood. The already marked importance of weight control in youth is further strengthened by these findings, as well as greater evidence for obesity as a potential important cause of adverse cardiac remodeling that is independent of clinically evident ischemic heart disease.

Decrease in loop diuretic treatment from 2005 to 2014 in Swedish real-life patients with chronic heart failure.

PURPOSE: Loop diuretics are recommended to treat congestive symptoms in patients with heart failure. However, observational studies have indicated that loop diuretic treatment in heart failure is associated with increased mortality. Therefore, loop diuretic discontinuation or dose reduction, when clinically possible, is recommended. Our aim was to study nationwide temporal trends in loop diuretic treatment from 2005 to 2014 in real-life patients with chronic heart failure. METHODS: Data from the nationwide Swedish National Patient, Prescribed Drug and Cause of Death Registers were linked. The annual proportions of patients with chronic heart failure treated with loop diuretics from 2005 to 2014 were calculated. In addition, the annual median loop diuretic doses (DDD) in patients with chronic heart failure treated with loop diuretics from 2005 to 2014 were calculated. RESULTS: The proportion of real-life patients with chronic heart failure treated with loop diuretics decreased from 73.2% in 2005 to 65.7% in 2014 (p for trend < 0.001). The median loop diuretic DDD in real-life patients with chronic heart failure decreased from 2.13 (IQR 1.09-2.77) in 2005 to 1.63 (IQR 1.09-2.25) in 2014 (p = 0.001 for trend). CONCLUSIONS: Loop diuretic treatment decreased from 2005 to 2014 in real-life patients with chronic heart failure. The prognostic impact of changes in loop diuretic treatment in patients with heart failure remains unclear.

Short atrioventricular delay pacing therapy in young and old patients with hypertrophic obstructive cardiomyopathy: good long-term results and a low need for reinterventions.

Aims: Examination of long-term results following different treatments in hypertrophic obstructive cardiomyopathy (HOCM) in a complete geographical cohort. Methods and results: HOCM patients attending during 2002-13 in all 10 hospitals in the West Götaland Region, Sweden, were identified (n = 251), follow-up 14.4 (±8.9) years (mean ± SD), 121 managed medically, 42 treated with myectomy and 88 with short atrioventricular (AV) delay pacing as first interventional procedure. Post-intervention follow-up was 12.9 ± 8.7 years and 12.2 ± 5.0 years, respectively. Both intervention treatments improved New York Heart Association (NYHA) class and outflow gradients significantly. Patients treated with pacing were older (median age 64 vs. 43 years, P < 0.001). Freedom from disease-related death post-procedure at 5, 10, and 20 years were 93%, 80%, 56% vs. 93%, 93%, 57% in pacing and myectomy groups, respectively (log-rank P = 0.43). Survival after diagnosis was not different in patients just treated conservatively (P = 0.51 pacing/conservative; P = 0.39 myectomy/conservative). Reintervention for outflow gradients in patients ≥18 years at procedure occurred in 3.5% in pacing group and 15.6% in myectomy group (P = 0.007). Pacing therapy was equally effective in patients aged 13-64 years (n = 44), as in patients ≥65 years (n = 44): resting gradient pre-procedure and at last follow-up were median (IQR) 65 (71) and 12 (20) mmHg for <65 year-olds (P < 0.001), and 75 (64) and 14 (38) mmHg, respectively, for ≥65 year-olds (P < 0.001). New York Heart Association class improved significantly in both age ranges to 1.6 ± 0.6 and 1.8 ± 0.7, respectively (P < 0.001; P < 0.001). Conclusion: Short AV delay pacing provided lasting satisfactory relief of symptoms and outflow obstruction in the majority of patients, with low risk of requiring reintervention. Our findings support the view that pacing therapy should be considered a valid option to treat patients with HOCM.

Fathers' experiences of care when their partners suffer from peripartum cardiomyopathy: a qualitative interview study.

BACKGROUND: Peripartum cardiomyopathy (PPCM), a potentially life-threatening condition in women, can have a profound impact on the family. Although structured support systems are developed, these systems tend to be based on the healthcare providers' perceptions and focus mainly on mothers' care. Fathers' vital role in supporting their partners has been advocated in previous research. However, the impact of PPCM on the male partners of women is less understood. The aim of this study was to explore the experiences of healthcare in fathers whose partner was suffering from peripartum cardiomyopathy. METHODS: The data from interviews with fourteen fathers were analysed using inductive content analysis. RESULTS: An overarching category "The professionals could have made a difference" was identified from the data, characterised by the sub-categories: 'To be informed/not informed,' 'To feel secure/insecure,' 'To feel visible/invisible' and 'Wish that it had been different'. Lack of timely information did not allow fathers to understand their partner´s distress, and plan for the future. The birth of the child was an exciting experience, but a feeling of helplessness was central, related to seeing their partner suffering. A desire for follow-up regarding the effect of PPCM on themselves was expressed. CONCLUSIONS: When men, as partners of women with PPCM, get adequate information of their partner´s condition, they gain a sense of security and control that gives them strength to handle their personal and emotional life-situation during the transition of becoming a father, along with taking care of an ill partner with PPCM. Hence, maternity professionals should also focus on fathers' particular needs to help them fulfil their roles. Further research is urgently required in this area.

Body weight in adolescence and long-term risk of early heart failure in adulthood among men in Sweden.

AIMS: To study the relation between body mass index (BMI) in young men and risk of early hospitalization with heart failure. METHODS AND RESULTS: In a prospective cohort study, men from the Swedish Conscript Registry investigated 1968-2005 (n = 1 610 437; mean age, 18.6 years were followed 5-42 years (median, 23.0 years; interquartile range, 15.0-32.0), 5492 first hospitalizations for heart failure occurred (mean age at diagnosis, 46.6 (SD 8.0) years). Compared with men with a body mass index (BMI) of 18.5-20.0 kg/m2, men with a BMI 20.0-22.5 kg/m2 had an hazard ratio (HR) of 1.22 (95% CI, 1.10-1.35), after adjustment for age, year of conscription, comorbidities at baseline, parental education, blood pressure, IQ, muscle strength, and fitness. The risk rose incrementally with increasing BMI such that men with a BMI of 30-35 kg/m2 had an adjusted HR of 6.47 (95% CI, 5.39-7.77) and those with a BMI of ≥35 kg/m2 had an HR of 9.21 (95% CI, 6.57-12.92). The multiple-adjusted risk of heart failure per 1 unit increase in BMI ranged from 1.06 (95% CI, 1.02-1.11) in heart failure associated with valvular disease to 1.20 (95% CI, 1.18-1.22) for cases associated with coronary heart disease, diabetes, or hypertension. CONCLUSION: We found a steeply rising risk of early heart failure detectable already at a normal body weight, increasing nearly 10-fold in the highest weight category. Given the current obesity epidemic, heart failure in the young may increase substantially in the future and physicians need to be aware of this.

Heart Failure in Late Pregnancy and Postpartum: Incidence and Long-Term Mortality in Sweden From 1997 to 2010.

BACKGROUND: Heart failure (HF) in late pregnancy and postpartum (HFPP), of which peripartum cardiomyopathy (PPCM) constitutes the larger part, is still a rare occurrence in Sweden. Population-based data are scarce. Our aim was to characterize HFPP and determine the incidence and mortality in a Swedish cohort. METHODS AND RESULTS: Through merging data from the National Inpatient, Cause of Death, and Medical Birth Registries, we identified ICD-10 codes for HF and cardiomyopathy within 3 months before delivery to 6 months postpartum. Each case was assigned 5 age-matched control subjects from the Medical Birth Registry. From 1997 to 2010, 241 unique HFPP case subjects and 1063 matched control subjects were identified. Mean incidence was 1 in 5719 deliveries. HFPP was strongly associated with preeclampsia (odds ratio [OR] 11.91, 95% confidence interval [CI] 7.86-18.06), obesity (OR 2.5, 95% CI 1.7-3.7), low- and middle-income country (LMIC) of origin (OR 1.73, 95% CI 1.14-2.63), and twin deliveries (OR 4.39 CI 95% 2.24-8.58). By the end of the study period deaths among cases were >35-fold those of controls: 9 cases (3.7 %) and 1 control (0.1 %; P < .0001). Among control subjects, 17.9% of mortalities occurred within 3 years, of diagnosis compared with 100% among cases. CONCLUSIONS: The mean incidence and mortality among women with HFPP in Sweden from 1997 to 2010 was low but carried a marked excess risk of death compared with control subjects and was strongly linked to preeclampsia, obesity, multifetal births, and LMIC origin of the mother.

Obesity in Middle Age Increases Risk of Later Heart Failure in Women-Results From the Prospective Population Study of Women and H70 Studies in Gothenburg, Sweden.

OBJECTIVE: Obesity has been shown to be a risk factor for heart failure (HF), but whether the association varies by age is not understood. The aim was to examine the impact of obesity/overweight on the risk of developing heart failure in women of different ages by analysing prospective data from 2 population studies. METHODS: Data were obtained from the Population Study of Women in Gothenburg and the Gerontologic and Geriatric Population Studies concerning body mass index (BMI) collected in 1980 or later. Follow-up ended in 2006. Cox proportional hazard methods were used to determine associations between developing HF and BMI in 2574 women, 1243 aged 26-65 years and 1331 aged 66-76 years, at baseline. RESULTS: Women aged 26-65 years at baseline with BMI ≥30 kg/m2 had an increased risk of developing HF (hazard ratio [HR] 2.61, 95% confidence interval [CI] 1.56-4.35) even when controlling for age, glucose, smoking, alcohol consumption, serum triglycerides, and systolic blood pressure (reference group: women with BMI 18.5-22.4 kg/m2). Obese women aged 66-76 years at baseline did not show increased risk of developing HF (HR 0.55, 95% CI 0.23-1.29). CONCLUSIONS: Obesity in middle-age women increases their risk of developing HF later in life. In contrast, obesity later in life shows no association with HF.

Optimizing the Management of Heart Failure With Preserved Ejection Fraction in the Elderly by Targeting Comorbidities (OPTIMIZE-HFPEF).

AIMS: The pathophysiology of heart failure with preserved ejection fraction (HFPEF) is not fully understood. A recently proposed mechanism for HFPEF is that it is a systemic pro-inflammatory state induced by comorbidities, leading to microvascular endothelial dysfunction and subsequent cardiac remodeling and dysfunction. We hypothesize that targeting comorbidities will improve outcomes in elderly patients with HFPEF. Thus, the aim of this study is to determine whether the combination of systematic screening and optimal management of prespecified comorbidities associated with HFPEF improves outcomes. METHODS: This multicenter, prospective, randomized intervention trial uses an open procedure with blinded endpoint assessment. Patients with HFPEF aged >60 years (n = 360) will be randomized 1:1 to the usual care or intervention arm of the trial. When randomized to the intervention arm, all patients will be systematically screened and optimally treated for the most frequent cardiovascular, metabolic, respiratory, and renal comorbidities. The primary endpoint is a composite clinical score that classifies each randomized patient as improved or deteriorated based on objective and subjective data at a 24-month follow-up performed by a blinded endpoint committee. CONCLUSION: Rather than targeting cardiac dysfunction, our study aims to present evidence for a possible paradigm shift in the management of HFPEF. Our novel concept focuses on the management of comorbidities as predisposing factors in HFPEF.

Experiences of health care in women with Peripartum Cardiomyopathy in Sweden: a qualitative interview study.

BACKGROUND: Peripartum cardiomyopathy is often associated with severe heart failure occurring towards the end of pregnancy or in the months following birth with debilitating, exhausting and frightening symptoms requiring person-centered care. The aim of this study was to explore women's experiences of health care while being diagnosed with peripartum cardiomyopathy. METHOD: Qualitative interviews were conducted with 19 women with peripartum cardiomyopathy in Sweden, following consent. Data were analysed using qualitative content analysis. Confirmability was ensured by peer-debriefing, and an audit trail was kept to establish the credibility of the study. RESULTS: The main theme in the experience of health care was, 'Exacerbated Suffering', expressed in three subthemes; 'not being cared about', 'not being cared for' and 'not feeling secure.' The suffering was present in relation to the illness with failing health symptoms, but most of all in relation to not being taken seriously and adequately cared for by healthcare professionals. Women felt they were on an assembly line in midwives' routine work where knowledge about peripartum cardiomyopathy was lacking and they showed distrust and dissatisfaction with care related to negligence and indifference experienced from healthcare professionals. Feelings of being alone and lost were prominent and related to a sense of insecurity, distress and uneasiness. CONCLUSIONS: This study shows a knowledge gap of peripartum cardiomyopathy in maternity care personnel. This is alarming as the deprecation of symptoms and missed diagnosis of peripartum cardiomyopathy can lead to life-threatening consequences. To prompt timely diagnosis and avoid unnecessary suffering it is important to listen seriously to, and respect, women's narratives and act on expressions of symptoms of peripartum cardiomyopathy, even those overlapping normal pregnancy symptoms.

Body weight in midlife and long-term risk of developing heart failure-a 35-year follow-up of the primary prevention study in Gothenburg, Sweden.

BACKGROUND: This study aimed to determine whether midlife obesity predicts heart failure (HF) over an extended follow-up into old age. METHODS: We studied 7495 men (from a population sample of 9,998 men) without HF, who were 47-55 years old when investigated in 1970 to 1973. All participants were followed up for 35 years, or until death, using the Swedish National Inpatient Register (IPR) and the Cause of Death Register. Over follow-up, 1855 men (24.7%) were discharged from hospital or died with a diagnosis of HF. RESULTS: There was a strong relation between obesity and future risk of HF, which was accentuated over the last years of the long follow-up. After adjusting for age, the risk of HF increased stepwise with increasing body mass index (BMI), even in those with a normal BMI (22.5-24.9) The subdistribution hazard ratio (SHR) was 1.20 (95% CI: 1.02-1.39) in men with a normal BMI, 1.29 (95% CI: 1.11-1.50) for a BMI of 25-27.49, 1.50 (95% CI: 1.27-1.77) for a BMI of 27.5-29.99, and 1.62 (95% CI: 1.33-1.97) for a BMI >30. After adjusting for, age, smoking, occupational class, and physical activity, the results were unchanged. CONCLUSION: Obesity in midlife is strongly related to the long-term risk of developing HF extending into old age where the risk is highest. Even normal body weight (BMI <25) was related to an increased risk of developing HF during life. Because overweight and obesity are largely preventable, our findings further emphasize the importance of public health interventions against the development of obesity.

Heart failure in young adults: 20-year trends in hospitalization, aetiology, and case fatality in Sweden.

AIMS: To describe trends in incidence and case fatality among younger (18-54 years) and older (55-84 years) Swedish patients with heart failure (HF). METHODS AND RESULTS: Through linking the Swedish national hospital discharge and the cause-specific death registries, we identified patients aged 18-84 years that were discharged 1987-2006 with a diagnosis of HF. Age-specific mean incidence rates per 100 000 person-years were calculated in four 5-year periods. Kaplan-Meier survival curves were plotted up to 3 years. From 1987 to 2006, there were 443 995 HF hospitalizations among adults 18-84 years. Of these, 4660 (1.0%) and 13 507 (3.0%) occurred in people aged 18-44 and 45-54 years (31.6% women), respectively. From the first to the last 5-year period, HF incidence increased by 50 and 43%, among people aged 18-34 and 35-44 years, respectively. Among people ≥45 years, incidence peaked in the mid-1990s and then decreased. Heart failure in the presence of cardiomyopathy increased more than two-fold among all age groups. Case fatality decreased for all age groups until 2001, after which no further significant decrease <55 years was observed. CONCLUSION: Increasing HF hospitalization in young adults in Sweden opposes the general trend seen in older patients, a finding which may reflect true epidemiological changes. Cardiomyopathy accounted for a substantial part of this increase. High case fatality and lack of further case fatality reduction after 2001 are causes for concern.

Heart disease in pregnancy and risk of pre-eclampsia: a Swedish register-based study.

BACKGROUND AND AIMS: Pre-eclampsia complicates 3-5% of pregnancies worldwide and is associated with adverse outcomes for the mother and the offspring. Pre-eclampsia and heart failure have common risk factors, including hypertension, obesity and diabetes. It is not known whether heart failure increases the risk of pre-eclampsia. This study examines whether pregestational heart failure increases the risk of pre-eclampsia. METHODS: In a registry-based case-cohort study that included all pregnancies in Sweden (n=3 125 527) between 1990 and 2019, all pregnancies with pre-eclampsia (n=90 354) were identified and up to five control pregnancies (n=451 466) for each case were chosen, matched on the mother's birth year. Multiple logistic regression analysis was used to evaluate the impact of heart failure on the risk of pre-eclampsia, with adjustment for established risk factors and other cardiovascular diseases. RESULTS: Women with heart failure had no increased risk for pre-eclampsia, OR 1.02 (95% CI 0.69 to 1.50). Women with valvular heart disease had an increased OR of preterm pre-eclampsia, with an adjusted OR of 1.78 (95% CI 1.04 to 3.06). Hypertension and diabetes were independent risk factors for pre-eclampsia. Obesity, multifetal pregnancies, in vitro fertilisation, older age, Nordic origin and nulliparity were more common among women who developed pre-eclampsia compared with controls. CONCLUSION: Women with heart failure do not have an increased risk of pre-eclampsia. However, women with valvular heart disease prior to pregnancy have an increased risk of developing preterm pre-eclampsia independent of other known risk factors.

Effects of person-centred care in patients with chronic heart failure: the PCC-HF study.

AIMS: Person-centred care (PCC) emphasizes a partnership in care between patients and healthcare professionals and is advocated by WHO as a key component of quality health care. We evaluated outcomes of PCC in hospitalized patients with chronic heart failure (CHF) with respect to the length of hospital stay (LOS), activities of daily living (ADL), health-related quality of life (HRQL) and 6-month readmission rate. METHODS AND RESULTS: During 2008-2010, 248 consecutive patients hospitalized for symptoms of worsening CHF were enrolled in a controlled before and after designed study. A Usual care group (n= 123) was recruited according to pre-defined criteria to map usual CHF care and assess outcomes at five designated hospital wards. Based on the mapping, a panel of in-house clinicians and researchers developed measures aimed at aligning usual care with basic PCC principles. These measures were incorporated into a study protocol to guide care procedures at the same five wards. Person-centred care was then implemented at these wards and evaluated in 125 patients. Both length of hospital stay and 6-month readmission were extracted from patient records. Activities of daily living were evaluated at baseline and discharge and HRQL was evaluated at baseline and after 3 months. In the analysis of all patients, the LOS was reduced by 1 day (P = 0.16) while retaining ADL (P = 0.07). When PCC was fully implemented (per protocol analysis), LOS was reduced by 2.5 days (P = 0.01) and the ADL-level better preserved (P = 0.04). Health-related quality of life and time-to-first readmission did not differ. CONCLUSION: In this proof-of-concept study, our findings suggest that a fully implemented PCC approach shortens hospital stay and maintains functional performance in patients hospitalized for worsening CHF, without increasing risk for readmission or jeopardizing patients' HRQL.

Body Weight in Adolescent Men in Sweden and Risk of an Early Acute Coronary Event: A Prospective Population-Based Study.

Background Coronary heart disease remains the dominant cause of death worldwide. To improve cardiovascular disease prevention, knowledge of early key risk factors, especially those that are modifiable, is essential. The ongoing global obesity epidemic is of particular concern. We aimed to determine whether body mass index at conscription predicts early acute coronary events among men in Sweden. Methods and Results This was a population-based Swedish cohort study of conscripts (n=1 668 921; mean age, 18.3 years; 1968-2005), with follow-up through linkage to the nationwide Swedish patient and death registries. Risk of a first acute coronary event (hospitalization for acute myocardial infarction or coronary death) during follow-up (1-48 years) was calculated with generalized additive models. Objective baseline measures of fitness and cognition were included in the models in secondary analyses. During follow-up, there were 51 779 acute coronary events, of which 6457 (12.5%) were fatal within 30 days. Compared with men at the lowest end of the normal body mass index spectrum (body mass index, 18.5 kg/m2), an increasing risk for a first acute coronary event was observed, with hazard ratios (HRs) peaking at 40 years of age. After multivariable adjustments, men with a body mass index of 35 kg/m2 had an HR of 4.84 (95% CI, 4.29-5.46) for an event before the age of 40 years. Conclusions An increased risk of an early acute coronary event was detectable within normal levels of body weight at the age of 18 years, increasing to almost 5-fold in the highest weight category at 40 years of age. Given increasing levels of body weight and prevalence of overweight and obesity in young adults, the current decrease in coronary heart disease incidence in Sweden may flatten or even reverse in the near future.

Attitudes among healthcare professionals towards ICT and home follow-up in chronic heart failure care.

BACKGROUND: eHealth applications for out-of-hospital monitoring and treatment follow-up have been advocated for many years as a promising tool to improve treatment compliance, promote individualized care and obtain a person-centred care. Despite these benefits and a large number of promising projects, a major breakthrough in everyday care is generally still lacking. Inappropriate organization for eHealth technology, reluctance from users in the introduction of new working methods, and resistance to information and communication technology (ICT) in general could be reasons for this. Another reason may be attitudes towards the potential in out-of-hospital eHealth applications. It is therefore of interest to study the general opinions among healthcare professionals to ICT in healthcare, as well as the attitudes towards using ICT as a tool for patient monitoring and follow-up at home. One specific area of interest is in-home follow-up of elderly patients with chronic heart failure (CHF). The aim of this paper is to investigate the attitudes towards ICT, as well as distance monitoring and follow-up, among healthcare professionals working with this patient group. METHOD: This paper covers an attitude survey study based on responses from 139 healthcare professionals working with CHF care in Swedish hospital departments, i.e. cardiology and medicine departments. Comparisons between physicians and nurses, and in some cases between genders, on attitudes towards ICT tools and follow-up at home were performed. RESULTS: Out of the 425 forms sent out, 139 were collected, and 17 out of 21 counties and regions were covered in the replies. Among the respondents, 66% were nurses, 30% physicians and 4% others. As for gender, 90% of nurses were female and 60% of physicians were male. Internet was used daily by 67% of the respondents. Attitudes towards healthcare ICT were found positive as 74% were positive concerning healthcare ICT today, 96% were positive regarding the future of healthcare ICT, and 54% had high confidence in healthcare ICT. Possibilities for distance monitoring/follow-up are good according to 63% of the respondents, 78% thought that this leads to increased patient involvement, and 80% thought it would improve possibilities to deliver better care. Finally, 72% of the respondents said CHF patients would benefit from home monitoring/follow-up to some extent, and 19% to a large extent. However, the best method of follow-up was considered to be home visits by nurse, or phone contact. CONCLUSION: The results indicate that a majority of the healthcare professionals in this study are positive to both current and future use of ICT tools in healthcare and home follow-up. Consequently other factors have to play an important role in the slow penetration of out-of-hospital eHealth applications in daily healthcare practice.
