- BACKGROUND/OBJECTIVE:: This study attempted a national inventory of all bilateral prophylactic mastectomies performed in Sweden between 1995 and 2005 in high-risk women without a previous breast malignancy. The primary aim was to investigate the breast cancer incidence after surgery. Secondary aims were to describe the preoperative risk assessment, operation techniques, complications, histopathological findings, and regional differences. METHODS:: Geneticists, oncologists and surgeons performing prophylactic breast surgery were asked to identify all women eligible for inclusion in their region. The medical records were reviewed in each region and the data were analyzed centrally. The BOADICEA risk assessment model was used to calculate the number of expected/prevented breast cancers during the follow-up period. RESULTS:: A total of 223 women operated on in 8 hospitals were identified. During a mean follow-up of 6.6 years, no primary breast cancer was observed compared with 12 expected cases. However, 1 woman succumbed 9 years post mastectomy to widespread adenocarcinoma of uncertain origin. Median age at operation was 40 years. A total of 58% were BRCA1/2 mutation carriers. All but 3 women underwent breast reconstruction, 208 with implants and 12 with autologous tissue. Four small, unifocal, invasive cancers and 4 ductal carcinoma in situ were found in the mastectomy specimens. The incidence of nonbreast related complications was low (3%). Implant loss due to infection/necrosis occurred in 21 women (10%) but a majority received a new implant later. In total, 64% of the women underwent at least 1unanticipated secondary operation. CONCLUSIONS:: Bilateral prophylactic mastectomy is safe and efficacious in reducing future breast cancer in asymptomatic women at high risk. Unanticipated reoperations are common. Given the small number of patients centralization seems justified.

- Aims To evaluate long-term all-cause risk of mortality in women and men hospitalized for the first time with atrial fibrillation (AF) compared with matched controls. Methods and results A total of 272 186 patients (44% women) <= 85 years at the time of hospitalization with incidental AF 1995-2008 and 544 344 matched controls free of in-hospital diagnosis of AF were identified. Patients were followed via record linkage of the Swedish National Patient Registry and the Cause of Death Registry. Using Cox regression models, the long-term relative all-cause mortality risk, adjusted for concomitant diseases, in women vs. controls was 2.15, 1.72, and 1.44 (P < 0.001) in the age categories <= 65, 65-74, and 75-85 years, respectively. The corresponding figures for men were 1.76, 1.36, and 1.24 (P < 0.001). Among concomitant diseases, neoplasm, chronic renal failure, and chronic obstructive pulmonary disease contributed most to the increased all-cause mortality vs. controls. In patients with AF as the primary diagnosis, the relative risk of mortality was 1.63, 1.46, and 1.28 (P < 0.001) in women and 1.45, 1.17, and 1.10 (P < 0.001) in men. Conclusion Atrial fibrillation was an independent risk factor of all-cause mortality in patients with incident AF. The concomitant diseases that contributed most were found outside the thromboembolic risk scores. The highest relative risk of mortality was seen in women and in the youngest patients compared with controls, and the differences between genders in each age category were statistically significant.

- Background: Previous studies of patients with "lone" and "idiopathic" atrial fibrillation (AF) have provided conflicting evidence concerning the development, management and prognosis of this condition. Methods: In this nation-wide, retrospective, cohort study, we studied patients diagnosed with incidental AF recorded in national Swedish registries between 1995 and 2008. Controls were matched for age, sex and calendar year of the diagnosis of AF in patients. All subjects were free of any in-hospital diagnosis from 1987 and until patients were diagnosed with AF and also free of any diagnosis within one year from the time of inclusion. Follow-up continued until 2009. We identified 9519 patients (31% women) and 12,468 matched controls. Results: Relative risks (RR) versus controls for stroke or transient ischemic attack (TIA) in women were 19.6, 4.4, 3.4 and 2.5 in the age categories <55, 55-64, 65-74 and 75-85, years respectively. Corresponding figures for men were 3.4, 2.5, 1.7 and 1.9. RR for heart failure were 6.6, 6.6, 6.3 and 3.8 in women and 7.8, 4.6, 4.9 and 2.9 in men. All RR were statistically significant with p < 0.01. RR for myocardial infarction and all-cause mortality were statistically significantly increased only in the two oldest age categories in women and 65-74 years in men. Conclusions: Patients with AF and no co-morbidities at inclusion had at least a doubled risk of stroke or TIA and a tripled risk of heart failure, through all age categories, as compared to controls. Women were at higher RR of stroke or TIA than men. (C) 2014 The Authors. Published by Elsevier Ireland Ltd.

- Aims There is controversy in the guidelines as to whether patients with atrial fibrillation and a low risk of stroke should be treated with anticoagulation, especially those with a CHA(2)DS(2)-VASc score of 1 point. In a retrospective, nationwide cohort study, we used the Swedish National Patient Registry, the National Prescribed Drugs Registry, the Swedish Registry of Education and the Population and Housing Census Registry. 48 433 patients were identified between 1 January 2006 and 31 December 2008 with incident atrial fibrillation who were divided in age categories, sex and a CHA(2)DS(2)-VASc score of 0, 1, 2 and >= 3 and they were included in a time-varying analysis of warfarin treatment versus no treatment. The primary end-point was cerebral infarction and stroke, and patients were followed until 31 December 2009. Patients with 1 point from the CHA(2)DS(2)-VASc score showed the following adjusted hazard ratios (HR) with a 95% confidence interval: men 65-74 years 0.46 (0.25-0.83), men < 65 years 1.11 (0.56-2.23) and women < 65 years 2.13 (0.94-4.82), where HR < 1 indicates protection with warfarin. In patients < 65 years and 2 points, HR in men was 0.35 (0.18-0.69) and in women 1.84 (0.86-3.94) while, in women with at least 3 points, HR was 0.31 (0.16-0.59). In patients 65-74 years and 2 points, HR in men was 0.37 (0.23-0.59) and in women 0.39 ( 0.21-0.73). Categories including age >= 65 years or >= 3 points showed a statistically significant protection from warfarin. Our results support that treatment with anticoagulation may be considered in all patients with an incident atrial fibrillation diagnosis and an age of 65 years and older, i.e. also when the CHA(2)DS(2)-VASc score is 1.

- BACKGROUND: Little is known about the long-term, cause-specific mortality risk in patients without comorbidities at the time of diagnosis of atrial fibrillation (AF).METHODS: From a nation-wide registry of patients hospitalized with incident AF between 1995 and 2008 we identified 9 519 patients with a first diagnosed AF and no comorbidities at the time of AF diagnosis. They were matched with 12 468 controls. The follow-up continued until December 2008. Causes of death were classified according to the ICD-10 codes.RESULTS: During follow-up, 11.1% of patients with AF and 8.3% of controls died. Cardiovascular diseases were the most common causes of death and the only diagnoses which showed significantly higher relative risk in patients with AF than controls (HR 2.0, 95% CI 1.8-2.3), and the relative risk was significantly higher in women than in men. Stroke was a more common cause among patients with AF, 13.1% versus 9.7% (HR 2.7, 95% CI 1.8-4.0), while cerebral hemorrhage was more common among controls, 4.7% versus 10.2% (HR 0.9, 95% CI 0.6-1.5). The time from AF diagnosis to death was 6.0 ± 3.1 years.CONCLUSIONS: In patients with incident AF and no known comorbidities at the time of AF diagnosis, only cardiovascular diseases were more often causes of death as compared to controls. Women carried a significantly higher relative risk than men.

Tidskriftsartikel (refereegranskat)abstract
- Life's Essential 8 (LE8) is a score that includes modifiable risk factors for cardiovascular disease. Four health behaviors (diet, physical activity, nicotine exposure and sleep health) and four health factors (non-HDL cholesterol, blood glucose, blood pressure and body mass index) are included. These modifiable risk factors promote inflammation, and inflammation is one of the biological mechanisms of cardiovascular disease development. Thus, we examined the relationship between cardiovascular health measured by LE8 and low-grade inflammation measured by high-sensitivity C-reactive protein (hs-CRP) in the cross-sectional population-based Swedish CArdioPulmonary bioImage Study (SCAPIS). The study consisted of 28,010 participants between 50 and 64 years (51.5% women, mean age 57.5 years). All individual LE8 components were assigned a score between 0 (unhealthy) and 100 (healthy) points, and a global score was calculated. The association between LE8 scores and high-risk hs-CRP (defined as > 3.0 mg/L) was analyzed using adjusted logistic regression with spline analyses. There was a strong, dose response and inverse association between LE8 scores and levels of hs-CRP. Thus, those with a low LE8 score (= 50.0 points) had 5.8 higher (95% confidence interval [CI] 5.2-6.4) odds ratio (OR) of having high hs-CRP as compared to those with a high LE8 score (= 80.0 points). In conclusion, our findings show strong inverse associations between LE8 scores and levels of hs-CRP.

- BACKGROUND: Differences in risk factor profiles between patients with ischemic and hemorrhagic stroke may have an impact on subsequent mortality. AIM: To explore cardiovascular disease risk factors, including the CHADS(2) score, with survival after ischemic or hemorrhagic stroke. METHODS: Between 2001 and 2005, 87111 (83%) ischemic stroke, 12497 (12%) hemorrhagic stroke, and 5435 (5%) patients with unspecified stroke were identified in the Swedish Stroke Register. Data on gender, age, and cardiovascular disease risk factors were linked to the Swedish Hospital Discharge and Cause of Death Registers. Adjusted odds and hazard ratios and 95% confidence interval were calculated using logistic and Cox proportional hazard regression models. RESULTS: Hemorrhagic stroke patients were younger than ischemic stroke patients. All cardiovascular disease risk factors studied, alone or combined in the CHADS(2) score, were associated with higher odds ratios for ischemic stroke vs. hemorrhagic stroke. Higher CHADS(2) scores and all studied risk factors except hypertension were associated with higher odds ratio for death by ischemic stroke than hemorrhagic stroke. Ischemic stroke was associated with lower early mortality (within 30 days) vs. hemorrhagic stroke (hazard ratio=0·28, confidence interval 0·27 to 0·29). CONCLUSIONS: Patients with hemorrhagic stroke had a higher risk of dying within the first 30 days after stroke, but the risk of death was similar in the two groups after one-month. Hypertension was the only cardiovascular disease risk factor associated with an increased mortality rate for hemorrhagic stroke as compared to ischemic stroke.

First-Ever Atrial Fibrillation Documented After Hemorrhagic or Ischemic Stroke : The Role of the CHADS(2) Score at the Time of Stroke
- 2011

Tidskriftsartikel (refereegranskat)abstract
- Background: The CHADS(2) score (C, congestive heart failure [CHF]; H, hypertension [HT]; A, age >= 75 y; D, diabetes mellitus; S-2, prior stroke or transient ischemic attack) is used to assess the risk of ischemic stroke in patients with atrial fibrillation (AF). However, its role in patients without documented AF is not well explored. Hypothesis: The goal of the current study was to explore if the incidence of hospitalization with first-ever AF after stroke increased with increasing CHADS(2) score. Methods: We identified 57 636 patients with nonfatal stroke and no documented AF in the Swedish Stroke Register (Riks-Stroke) during 2001-2004 and followed them for a mean of 2.2 years through record linkage to the Inpatient and Cause of Death registers. Cox regression hazard models were used to estimate the relative risk (RR) of new AF following stroke and its association with different CHADS(2) scores. Results: Overall, 2769 patients were hospitalized with new AF (4.8%, 21.7 per 1000 person-years). The incidence increased from 9.6 per 1000 person-years in CHADS(2) score 0 to 42.7 in CHADS(2) score 6, conferring a RR of 4.2 (95% confidence interval [CI]: 2.5-6.8). For CHADS(2) scores 3-5, the RRs were approximately 3 (vs CHADS(2) score 0). Adjusted RRs were 1.9 (95% CI: 1.7-2.1) for CHF, 1.4 (95% CI: 1.3-1.5) for HT, 2.1 (95% CI: 2.0-2.3) for age >= 75 years, 0.9 (95% CI: 0.8-1.0) for diabetes, and 1.0 (95% CI: 0.91-1.07) for previous stroke. The risk of AF was higher in ischemic than in hemorrhagic stroke. Conclusions: In this retrospective register study, the incidence of AF following stroke was strongly influenced by higher CHADS(2) scores where age >= 75 years, CHF, and HT were the contributing CHADS(2) components.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: This study examined all-cause mortality in stroke patients with and without documented atrial fibrillation (AF), and the impact of CHADS(2) score. DESIGN: A cohort of 105,074 patients, 31,821 (30.3%) with and 73,253 (69.7%) without documented AF, was studied. These patients were registered in the Swedish Stroke Registry during the years 2001-2005. Mortality data were retrieved from the Swedish Cause of Death Register. CHADS(2) score prior to stroke were assessed using the Swedish National Discharge Register. RESULTS: The age and sex adjusted relative risk (RR) of death was 1.46 (1.43-1.49) for AF vs non-AF patients. High age (>/=75 years) tripled the risk of death and was the single most important predictor, followed by congestive heart failure, previous stroke and diabetes. Less than half of the AF patients with a CHADS(2) score of 1-6 survived more than 5 years, whereas AF patients with a CHADS(2) score of 0 had a 73% chance of survival. In patients with AF, the relative risk of death was 6.05 (CI: 2.26-6.95); in subjects with the highest vs the lowest CHADS(2) score; the corresponding RR for non-AF patients was 7.93 (CI: 7.01-8.97). CONCLUSIONS: The CHADS(2) score seems to have an impact on all-cause mortality after stroke. The CHADS(2) score can give valuable insight for other outcome variables apart from having had an ischemic stroke and can be applied to patients with different risk factor profiles, e.g. with a previous known cardiovascular disease but without known AF.
