C-reactive protein (CRP) is a determinant of stroke, but there are no prospective studies on CRP and first ischemic stroke divided into etiologic subtypes. Our primary aim was to study CRP as a determinant of ischemic stroke, classified according to Trial of ORG 10172 in Acute Stroke Treatment (TOAST) criteria, and intracerebral hemorrhage (ICH) in a prospective study. A secondary aim was to study the relationship between the 1444C>T polymorphism, plasma levels of CRP and stroke.
The study was a prospective population-based case-referent study nested within the Northern Sweden Cohorts. We defined 308 cases of ischemic stroke and 61 ICH. Two controls for each case were defined from the same cohort.

More than half of cardiovascular mortality occurs outside the hospital, mainly due to consistently low survival rates from out-of-hospital cardiac arrest.
This is a prospective, nested, case-control study derived from the Västerbotten Intervention Programme and the World Health Organization's Multinational Monitoring of Trends and Determinants in Cardiovascular Disease study in northern Sweden (1986-2006). To determine predictors for sudden cardiac death risk factors for cardiovascular disease were compared between incident myocardial infarction with sudden cardiac death (n?=?363) and survivors of incident myocardial infarction (n?=?1998) using multivariate logistic regression analysis.
Diabetes had the strongest association with sudden cardiac death out of all evaluated risk factors (odds ratio (OR) 1.83, 95% confidence interval (CI) 1.30-2.59), followed by low education (OR 1.55, 95% CI 1.19-2.01), high body mass index (OR 1.05, 95% CI 1.02-1.08) and male sex (OR 1.42, 95% CI 1.001-2.01).
The pattern of risk factors for incident myocardial infarction is different among survivors and those who die within 24 hours. The risk factors that contribute the most to death within 24 hours are diabetes mellitus, high body mass index and low education level, and can be addressed at both the public health level and by general practitioners.
Chronic, low-grade inflammation is an established risk factor for cardiovascular disease. The inflammatory impact of diet can be reflected by concentrations of inflammatory markers in the bloodstream and the inflammatory potential of diet can be estimated by the dietary inflammatory index (DII(TM)), which has been associated with cardiovascular disease risk in some previous studies. We aimed to examine the association between the DII and the risk of first myocardial infarction (MI) in a population-based study with long follow-up.
We conducted a prospective case-control study of 1389 verified cases of first MI and 5555 matched controls nested within the population-based cohorts of the Northern Sweden Health and Disease Study (NSHDS), of which the largest is the ongoing VÃ¤sterbotten Intervention Programme (VIP) with nearly 100 000 participants during the study period. Median follow-up from recruitment to MI diagnosis was 6.4Â years (6.2 for men and 7.2 for women). DII scores were derived from a validated food frequency questionnaire (FFQ) administered in 1986-2006. Multivariable conditional logistic regression models were used to estimate odds ratios (OR) and 95% confidence intervals (CI), using quartile 1 (most anti-inflammatory diet) as the reference category. For validation, general linear models were used to estimate the association between the DII scores and two inflammatory markers, high-sensitivity C-reactive protein (hsCRP) and interleukin 6 (IL-6) in a subset (n?=?605) of the study population.
Male participants with the most pro-inflammatory DII scores had an increased risk of MI [ORQ4vsQ1?=?1.57 (95% CI 1.21-2.02) P trend?=?0.02], which was essentially unchanged after adjustment for potential confounders, including cardiovascular risk factors [ORQ4vsQ1?=?1.50 (95% CI 1.14-1.99), P trend?=?0.10]. No association was found between DII and MI in women. An increase of one DII score unit was associated with 9% higher hsCRP (95% CI 0.03-0.14) and 6% higher IL-6 (95% CI 0.02-0.11) in 605 controls with biomarker data available.
A pro-inflammatory diet was associated with an elevated risk of first myocardial infarction in men; whereas for women the relationship was null. Consideration of the inflammatory impact of diet could improve prevention of cardiovascular disease.

In an international perspective, Sweden has a very low case fatality after acute myocardial infarction (AMI). The aim of this study was to present trends and regional differences in case fatality within 28 days of the first AMI for males and females in Sweden after adjusting for co-morbidity. Adjustments in order to remove random effects on the rank order of county councils were made. The study was based on national data on more than 500,000 cases of AMI. Between 1987 and 1999, case fatality after AMI decreased from 47% to 37% among men and from 44% to 34% among women. The case fatality in the individual counties varied from 29% to 37% for men and from 31% to 40% for women. Further analysis is needed in order to explain these variations.
Renal denervation (RDN) is a catheter-based intervention to treat patients with resistant hypertension. The biological effects of RDN are not fully understood, and randomized controlled trials have generated conflicting evidence. This report presents data from the Swedish Registry for Renal Denervation, an investigator-driven nationwide registry.
To assess the safety and efficacy of RDN on patients with resistant hypertension in a real-world clinical setting.
This nationwide database contains patient characteristics, procedural details, and follow-up data on all RDN procedures performed in Sweden. Consecutive procedures between 2011 and 2015 were included.
The data analysis consists of 252 patients (mean age 61?±?10 years, 38% women; mean 4.5?±?1.5 antihypertensive drugs). Office SBP and DBP and 24-h ambulatory blood pressure (BP) decreased 6 months after RDN (176?±?23/97?±?17 to 161?±?26/91?±?16?mmHg, both P?
