1 Impact of Different Genetic Polymorphism on the Pulmonary Pressure in Patients With Pulmonary Hypertension of Different Cause With Special Focus on Patients With Chronic Heart Failure
Pulmonary Hypertension (PH) is a disease that is characterized by vasoconstriction of small vessels of the lung. Many cases do have proliferation of endothelial cells within these vessels. A possible influence of polymorphisms of genes relevant for inflammatory and endothelial processes is suspected. Especially patients with chronic heart failure can develope PH. The reasons therefore are lacking. The researchers investigate different polymorphism and the influence of these on pulmonary artery pressure (measured invasively) in patients with congestive heart failure (CHF) and patients with primary pulmonary hypertension.

Development of pressure ulcer (PU) is complex and multifactorial. The association of a constituted PU and of clinical / biological major elements is demonstrated and justifies. Prevention of PU is an important health priority, one that requires clear identification of risk factors.

Primary Outcomes
Description: Body Mass Index (BMI) is a simple index of weight-for-height. It is defined as the weight in kilograms divided by the square of the height in metres (kg/m2).
Measure: Anthropometric characteristics Time: one hourDescription: - Plasma levels glucose in mmol/l was measured by standard enzymatic methods using reagents in a fully automated analyzer Cx5 Pro-Bechman Coulter-Fuller-Ton
Measure: Diabetes mellitus Time: one hourDescription: Lipid markers: total serum cholesterol (CH), serum triglyceride, serum HDL- CH, in mmol/l, levels were measured by standard enzymatic methods using reagents in a fully automated analyzer (Randox Antrim, UK; CX9-BECKMANN). Low density lipoprotein cholesterol (LDL-C) in mmol / l was determined by Friedewald formula. non esterified fatty acids in serum was determined by colorimetric method at 550 nm (mmol/l)

Measure: Total antioxidant status Time: one hourDescription: Serum copper in μmol/l was indicated spectrophotometrically with RANDOX kit (Cat. No. CU 2340; Randox Labs Ltd., Crumlin, UK) at 580 nm according. Serum zinc was measured in μmol/l with RANDOX kit (Cat. No. ZN 2341; Randox Labs Ltd, Crumlin, UK) at 560 nm.
Measure: Determination of trace elements Time: one hourDescription: - Nutritional Risk Index (NRI) was originally derived from the serum albumin concentration and the ratio of present to usual weight [NRI = (1.489 x albumin, g/L) + (41.7 x present weight/ideal body weight)] and categorized as follows: severe risk (NRI < 83.5), moderate risk (83.5 < NRI < 97.5) and no risk (NRI > 97.5).
Measure: Nutritional status Time: 3 hoursDescription: - Prognostic Inflammatory and Nutritional Index (PINI) is a simple clinical [PINI = AAG x CRP / albumine x prealbumin] and classificated as follows: normal (1
Description: The bacterial colonization of a wound is a recognized detrimental factor in the multifactorial process of wound healing. wound per patient suffering from pressure ulcer was cultured by swab to determine the bacterial species of the infection and helps guide antibiotic therapy. The representative sample is collected before topical or systemic antibiotics are initiated and pain assessment should be conducted prior to wound procedures such as dressing changes and debridement. Bacterial swabs provide information on the predominant flora.
