Funktionsangiographie der kniegelenknahen Arterien: Konsequenzen für die Stentimplantation?
1990
Angiographic studies of the arteries adjoining the knee in 25 patients show extensive kinking and stenoses of the popliteal artery and less frequently of the distal femoral artery during flexion of the knee joint. This is due to the loss of elasticity with increasing age forcing the vessel into a tortuous course during shortening of the pathway of the popliteal artery with knee flexion. Independent of the principle of the different stents available they probably will not increase the contractility of the stented vessel in the longitudinal axis. It is to expect that after implantation of stents into the popliteal artery kinking will occur predominantly in the original segments of the vessel …
Opieka koordynowana po zawale serca. Stanowisko Polskiego Towarzystwa Kardiologicznego oraz Agencji Oceny Technologii Medycznych i Taryfikacji
2016
The in-hospital mortality following myocardial infarction has decreased substantially over the last two decades in Poland. However, according to the available evidence approximately every 10th patient discharged after myocardial infarction (MI) dies during next 12 months. We identified the most important barriers (e.g. insufficient risk factors control, insufficient and delayed cardiac rehabilitation, suboptimal pharmacotherapy, delayed complete myocardial revascularisation) and proposed a new nation-wide system of coordinated care after MI. The system should consist of four modules: complete revascularisation, education and rehabilitation programme, electrotherapy (including ICDs and BiVs …
Rhabdomyosarcoma of the head and neck in pediatric patients: a systematic review.
2022
Rhabdomyosarcoma (RMS) is a soft tissue malignant tumor of mesenchymal cell origin, which usually shows variable differentiation of muscle cells. It is the most common solid sarcoma in children. The most usual site of occurrence are the head and neck regions. RMS presents a variety of histologic features, and so differential diagnosis with other small round cell tumors is needed. Hence, it has been very useful to the field to undertake additional immunohistochemical studies to determine the diagnosis and, on occasions, to assign subtype tumors. A systematic review of three databases (Medline, Biological Science Collection and Health & Medical Collection) was carried out with the purpose of …
The Sick Adipose Tissue: New Insights Into Defective Signaling and Crosstalk With the Myocardium
2021
Adipose tissue (AT) biology is linked to cardiovascular health since obesity is associated with cardiovascular disease (CVD) and positively correlated with excessive visceral fat accumulation. AT signaling to myocardial cells through soluble factors known as adipokines, cardiokines, branched-chain amino acids and small molecules like microRNAs, undoubtedly influence myocardial cells and AT function via the endocrine-paracrine mechanisms of action. Unfortunately, abnormal total and visceral adiposity can alter this harmonious signaling network, resulting in tissue hypoxia and monocyte/macrophage adipose infiltration occurring alongside expanded intra-abdominal and epicardial fat depots seen …
Cirurgia coronària amb i sense circulació extracorpòria. Morbimortalitat postoperatòria i seguretat a curt i llarg terme
2016
OBJETIUS: Les malalties cardiovasculars representen el 25-40% de totes les morts a Europa i Amèrica del Nord amb una majoria causada per coronariopaties. La cirurgia de revascularització coronària amb circulació extracorpòria (CEC) segueix sent el “gold stàndard” del tractament quirúrugic d’aquesta patologia. Malgrat la millora de les tècniques i l'experiència quirúrgica, part de la morbiditat relacionada amb la cirurgia coronària és causada per la CEC i és per aquest motiu l’augment de procediments de revascularització coronària sense CEC les darreres dècades. L’ objectiu d’aquesta tesi és descriure l’experiència del nostre centre durant 20 anys (1993-2013) en la cirurgia cardiaca de revas…
Association of Oxidative Stress with Aortic Stiffness in Hypertensive Patients with Chronic Kidney Disease
2011
Several studies have consistently demonstrated that arterial stiffness becomes progressively worse as CKD progresses and a negative correlation of oxidative stress with renal function has been described. There is also sound experimental evidence indicating that oxidative stress is involved in atherogenesis. The contribution of oxidative stress to aortic stiffness is less clear. Aim: To analyse the relationship between plasma levels of 8-ISO-prostaglandin F2alpha (8-ISOPGF2alpha), an index of lipid peroxidation, considered a reliable biomarker of oxidative stress, and aortic stiffness in a group of hypertensive patients with chronic kidney disease. Methods: We enrolled 126 hypertensive patie…
Pacientu aprūpe pēc perifēro artēriju slimības
2020
Bakalaura darba tēma ir “Pacientu aprūpe pēc perifēro artēriju slimības”. Pētījuma problēma ir aktuāla, jo sirds – asinsvadu un asinsrites sistēmas slimības ir galvenais invaliditātes un priekšlaicīgas nāves cēlonis ekonomiski attīstītajās valstīs. Šo slimību medicīniskā un sociālā nozīme katru dienu palielinās, jo tās turpina attīstīties un izplatīties arvien vairāk, un tās ietekmē cilvēkus arvien jaunākā vecumā. Viena no šīm slimībām ir perifēro artēriju slimība, kuras cēlonis ir ateroskleroze 80–90% gadījumos, un kura ļoti bieži netiek diagnosticēta vai tiek diagnosticēta novēloti. Perifēro artēriju slimība ievērojami samazina cilvēka dzīves kvalitāti un var izraisīt dzīvībai bīstamas ko…
Plasma PAF-acetylhydrolase in patients with coronary artery disease: results of a cross-sectional analysis.
2003
Inflammation underlies both onset and perpetuation of atherosclerosis. Plasma lipoproteins transport the platelet-activating factor-acetylhydrolase (PAF-AH) with potentially anti-inflammatory activities. Our aim was to determine whether PAF-AH activity was associated with inflammatory markers and with coronary artery disease (CAD). PAF-AH activity and a panel of inflammatory mediators were measured in plasma of 496 patients with CAD and in 477 controls; 276 patients presented with stable angina pectoris and 220 with acute coronary syndrome (ACS). Individuals within the highest quartile of PAF-AH activity had an 1.8-fold increase in CAD risk [95% confidence interval (CI), 1.01 to 3.2; P = 0.…
Pirmreizējas sirds ritma izmaiņas pacientiem pēc atvērtās sirds operācijas
2019
Pēcoperācijas ātriju fibrilācija (POĀF) ir biežākā komplikācija pacientiem, kuriem veikta operācija uz atvērtas sirds. Kā rezultātā tā ietekmē morbiditāti, mortalitāti, kā arī palielina finansiālas izmaksas. Pētījuma mērķis ir uzzināt vai ir korelācija starp veiktiem pirms operācijas standarta izmeklējuma rezultātiem un pēcoperācijas ātriju fibrilāciju. Jo nosakot augsta riska pacientu var uzsākt preventīvu ārstēšanu. Materiāli un metodes: retrospektīvs pētījums, kur tika iekļauti pacienti, kam veikta sirds operācija ar sternotomijas pieeju, kuriem pirms operācijas bija sīnusa ritms n = 111. 39 pacienti netika iekļauti pētījumā, jo pirms operācijas bija ātriju fibrilācija vai anamnēzē ātrij…
Mid-term and late results of endovascular treatment for symptomatic carotid artery stenosis under proximal protection
2021
Introduction: Although filters are still preferred during carotid stenting, proximal protection systems (PPS) are increasingly used during these procedures. PPS seem to be safer than distal systems, especially in symptomatic patients, but evidence supporting their use is limited. Aim: This was a post hoc survey with 30-day mid-term and long-term follow up, which was aimed at assessment of the safety and efficacy of stenting of the internal carotid artery under PPS in symptomatic patients. Material and methods: We analysed the results of stenting in 120 symptomatic patients presenting with at least 60% stenosis. Patients were aged 67.9 ±9.8 years, and 12 patients were older than 80 years. An…
