- Aims: Previous studies have found that excessive sport activities are associated with an increased risk of atrial fibrillation (AF). Whether occupational physical activity (OPA) increases the risk for AF is not well studied. We aimed to examine whether OPA influences the risk of AF.Methods: 80,922 men and women, free from AF, completed in 1997 a questionnaire about their OPA at that time (baseline), and also retrospectively in 1997 their OPA at the age of 30 and 50 years. Participants were categorised into three groups (low, medium and high) based on OPA load. Participants were followed-up in the Swedish National Patient Register for ascertainment of AF. Cox proportional hazards regression models were used to estimate relative risks (RR) with 95% confidence intervals (CI), adjusted for potential confounders.Results: 11,614 cases of AF were diagnosed during follow-up time of up to 17 years. We observed an increased risk of AF in relation to increased load of OPA regardless of age. Compared with men who reported a low load of OPA, the multivariable RR (95% CI) for men with a high load was 1.10 (1.03-1.17) at 30 years, 1.11 (1.04-1.17) at 50 years and 1.19 (1.10-1.29) at baseline. The results for women were similar with multivariable RR of 1.16 (1.06-1.27) at 30 years, 1.14 (1.05-1.24) at 50 years and 1.11 (0.99-1.24) at baseline.Conclusion: These findings suggest that high load of OPA previous in life may play a role in increasing the risk for AF in both men and women.

- This study aimed to describe the safety and efficacy of covered stents in patients with coarctation of aorta (CoA) for immediate and long-term follow-up.Covered stents are increasingly being used in (re)CoA, mainly to reduce the risk of aortic wall injuries (AWI). However, limited data are available on intermediate and long-term outcome.In 89 patients (67.4% male) with a mean age of 23.9 ± 15.8 (min max range 5.1-71.6) years were 102 covered stents implanted (January 2003 - December 2017). Short-term pre/post-implant hemodynamics and angiographic data were reported. Changes in blood pressure, the use of antihypertensive drugs and complications were recorded during follow-up.The procedural success rate was 100%. The mean invasive ascending-to-descending aorta systolic gradient under general anaesthesia decreased from 25 ± 16 mmHg to 4 ± 7 mmHg (p < 0.001). After a mean follow-up time of 6.6 ± 3.7 years, there was a persistent improvement of the mean systolic blood pressure gradient between right arm and leg (-7 ± 18 vs 38 ± 24 mmHg; p < 0.001). A larger proportion of patients required antihypertensive medication (33.7% vs 50.0%, p = 0.017) and needed ≥ 2 drugs (20.2% vs 27.4%, p = 0.066) to control blood pressure. Long-term adverse events were found in 4.5% of patients [covered stent fracture (n = 3), aneurysm formation (n = 2)].Covered stent implantation for CoA is highly successful, safe and results in a persistent hemodynamic improvement in the immediate and long-term outcome. Lifelong follow-up with additional antihypertensive drug treatment is mandatory to maintain favourable hemodynamic results after stenting.Long-term follow-up data on covered stents in patients with coarctation of the aorta are scarce. A cohort of 89 patients was reviewed. The procedural implantation success rate was 100%. The invasive gradient decreased from 25 ± 16 mmHg to 4 ± 7 mmHg (p < 0.001). After follow-up of 6.6 ± 3.7 years, there was a persistent improvement of the clinical systolic blood pressure gradient (-7 ± 18 vs 38 ± 24 mmHg; p < 0.001). However, a larger proportion of patients required antihypertensive medication (33.7% vs 50.0%, p = 0.017). Covered stent implantation results in favourable hemodynamic effects, but lifelong follow-up with additional antihypertensive drug treatment is mandatory to maintain these results.

- OBJECTIVE: The objective of this study was to explore the role of Chlamydia pneumoniae and Helicobacter pylori infections in patients with idiopathic permanent atrial fibrillation. METHODS AND RESULTS: Sera from 72 patients with permanent atrial fibrillation without structural heart disease (mean age 69.6 years, 23 women) were analysed for IgG antibodies against Chlamydia pneumoniae and Helicobacter pylori and compared in a I:I age- and sex-matched case:control manner with those pooled from a healthy reference population of 72 individuals from the same geographical area. After excluding patients with other possible or definite factors known either to cause atrial fibrillation or to affect the prevalence of seropositivity to these agents, the frequency of seropositivity due to one or both of the infectious agents was compared. Serum C-reactive protein (CRP) level was assessed using immunoturbidimetry technique. Both agents were equally common in men and women. Neither seropositivity to Chlamydia pneumoniae (76% vs. 83%, patients vs. control subjests, ns) nor to Helicobacter pylori (57% contra 55%, patients vs. controls, ns) alone reached significance in the comparisons between patients with atrial fibrillation and control subjects. Serum CRP was higher in patients with AF (5.3 mg/L vs. 2.8 mg/L, P < 0.001). CONCLUSIONS: Though presence of permanent AF is associated with elevated CRP levels, this elevation is not the result of earlier infections with Chlamydia pneumoniae or Helicobacter pylori or their combination.

- Background Histopathological changes in calcific aortic stenosis (CAS) resemble changes in coronary atherosclerosis. Concerning recent evidence on dietary and gut microbiota-related metabolites representing players in atherosclerosis, we aimed to investigate the link between dietary and gut microbiota-derived metabolites and CAS. Methods We consecutively recruited eligible subjects with moderate-severe CAS (n = 60), aortic sclerosis (ASc) (n = 49) and age and gender-matched control subjects (n = 48) in May 2016-December 2016. Plasma dietary and gut microbiota-related metabolite levels, namely choline, betaine, and trimethylamine N-oxide (TMAO), were measured using ultra-performance liquid chromatography-tandem mass spectroscopy method. Histopathological examinations were performed in patients that underwent aortic valve surgery. Results Prevalence of traditional cardiovascular risk factors or co-morbidities did not differ among groups (all p > 0.05). CAS patients had higher plasma choline levels compared to both control (p < 0.001) and ASc (p = 0.006). Plasma betaine and TMAO levels were similar (both p > 0.05). Compared to the lowest quartile choline levels (<11.15 mu M), patients with the highest quartile choline levels (>= 14.98 mu M) had higher aortic valvular (p < 0.001) and mitral annular (p = 0.013) calcification scores. Plasma choline levels were independently associated with aortic peak flow velocity (B +/- SE:0.165 +/- 0.060, p = 0.009). Choline levels were elevated in subjects who had aortic valves with denser lymphocyte infiltration (p < 0.001), neovascularization (p = 0.011), osseous metaplasia (p = 0.004), more severe tissue remodelling (p = 0.002) and calcification (p = 0.002). Conclusion We found a significant association between choline levels and CAS presence and severity depicted on imaging modalities and histopathological examinations. Our study may open new horizons for prevention of CAS.

- Cardiac rhabdonnyomas are rare and often regress spontaneously. However, the management of rhabdomyoma with severe inflow and outflow obstructions is a challenge. An infant with a massive left ventricular rhabdomyoma mimicking the haemodynamics of hypoplastic left heart syndrome is reported. Surgery could not be contemplated because the mitral valve leaflets and chordae were imbedded in the tumour mass. The arterial duct (AD) was kept open to perfuse the systemic circulation and palliations with pulmonary artery branch banding and AD stenting were planned. However; while waiting for spontaneous regression of the tumour, the child died of circulatory collapse when 4 weeks old.
