We sought to explore the relation between CVRF and the clinical characteristics of patients with HCM enrolled in the EURObservational Research Programme (EORP) Cardiomyopathy registry.
Methods and results: 1739 patients with HCM were studied. The relation between hypertension (HT), diabetes (DM), body mass index (BMI) and clinical traits was analyzed. Analyses were stratified according to the presence or absence of a pathogenic variant in a sarcomere gene.The prevalence of HT, DM and obesity (Ob) was 37%, 10%, and 21%, respectively. HT, DM and Ob were associated with older age (p<0.001), less family history of HCM (HT and DM p<0.001), higher New York Heart Association (NYHA) class (p<0.001), atrial fibrillation (HT and DM p<0.001; Ob p = 0.03) and LV (left ventricular) diastolic dysfunction (HT and Ob p<0.001; DM p = 0.003). Stroke was more frequent in HT (p<0.001) and mutation-positive patients with DM (p = 0.02). HT and Ob were associated with higher provocable LV outflow tract gradients (HT p<0.001, Ob p = 0.036). LV hypertrophy was more severe in Ob (p = 0.018). HT and Ob were independently associated with NYHA class (OR 1.419, p = 0.017 and OR 1.584, p = 0.004, respectively). Other associations, including a higher proportion of females in HT and of systolic dysfunction in HT and Ob, were observed only in mutation-positive patients.
Conclusion: Common CVRF are associated with a more severe HCM phenotype, suggesting a proactive management of CVRF should be promoted. An interaction between genotype and CVRF was observed for some traits.info:eu-repo/semantics/publishedVersio
Epidemiology and long-term survival of pulmonary arterial hypertension in the Czech Republic: a retrospective analysis of a nationwide registry
BACKGROUND: Pulmonary arterial hypertension (PAH) is a severe and progressive disease characterized by increased pulmonary vascular resistance, ultimately leading to right heart failure and death. Epidemiological data from national registries are growing worldwide, but are still unavailable in Eastern Europe. METHODS: A PAH registry was initiated in January 2007 using a nationwide network of echocardiographic centers and four diagnostic centers that specialize in PAH. All patients aged above 18 years, diagnosed with PAH and monitored between January 2000 and December 2007 were included. Patients diagnosed with PAH between January and December 2007 were classified as incident. The survival analyses were performed up to the end of 2010. Prognostic factors at the time of diagnosis were identified using uni- and multivariable Cox proportional hazard models. RESULTS: Overall, 191 patients were included (100 prevalent cases, 91 incident cases). Patients were predominantly female (n = 125) and had a mean age of 51.9 ± 16.9 years. Incident patients were significantly older at the time of diagnosis than prevalent patients (p < 0.001). Most patients (60.7%) had idiopathic PAH; 20.4% had PAH associated with congenital heart disease and 11.4% had PAH associated with connective tissue disease. Estimates of prevalence and incidence of PAH in adults were 22.4 cases per million and 10.7 cases per million per year, respectively. The 1-, 2- and 3-year survival rates in the incident PAH cohort were 89% (95% confidence intervals [CI] 83–95%), 78% (95% CI 70–87%) and 74% (95% CI 65–83%), respectively. Lower survival rates were significantly associated with higher age (hazard ratio [HR] 6.6 95% CI 1.4–30.9) and lower creatinine clearance (HR 3.3 95% CI 1.1–9.7). CONCLUSION: This is the first study in Eastern Europe to describe the prevalence, incidence and survival of patients with PAH from a national representative registry. This registry from the Czech Republic highlights that diagnosis of PAH is frequently made late in the disease continuum when patients have significant functional impairment

Placental growth factor may predict increased left ventricular mass index in patients with mild to moderate chronic kidney disease – a prospective observational study
”Økende antall traumepasienter til UUS: Hvem er de, og hvorfor kommer de?”
Background: Ullevål University Hospital is a level I trauma center, servicing approximately half of Norway's population. During the years 2001 to 2006, the number of trauma patients has increased 30 %, from 835 to 1089 per year. The present paper aimed to explore the reasons behind this increase.
Material and methods: Analysis of trauma patients included in the Ullevål University Hospital Trauma Registry in 2001-2006. Data points like age, sex, geographical place of trauma, type of injury, ISS score, and days of intensive care were used.
Results: The increase of the annual amount of trauma patients is a significant trend (P=0,01). The highest increase is in the group of patients injured outside Oslo and Akershus County, 69 %. This increase was mainly due to traffic accidents. One could also see a significant rise in amount of violence-related trauma, predominantly in Oslo. There was a rising demand on hospital resources, the total increase in days of intensive care of all trauma patients was 60 %.
Conclusions: The rising number of trauma patients is a clear trend, and leads to a significant increase in demands of hospital care, especially intensive care. This trend should be taken into consideration in future plans for the regional trauma system
Strength Analysis of AL-7F-1 Engine Turbine Rotor Blade
The key intent of the article is to describe clearly the strength issue of blades for aircraft engines, on the basis of which to create a calculation algorithm and apply it to a particular blade. The work then deals with a strength analysis of a rotor blade used in the gas turbine of an AL-7F-1 turbocharger aircraft engine. The article describes comprehensively in terms of strength the influences which act on the blade during operation. Generally, these loads can be divided into static load, which includes the tensile stress generated by the rotating mass of the blades, bending and torsion moments caused by the kinetic energy of the flowing gas. The last part of the article is dedicated to the issue of compensation of the bending moments acting on the turbine blades, resulting in analytical calculation of the blade inclination angles in the critical cross section.</jats:p
