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…

Kuormituskoe modernin kuvantamisen aikakaudella

2019

Kuormituskoetta käytetään sepelvaltimotaudin ja muidenkin sydänsairauksien diagnosoinnissa, ennusteen arvioinnissa, hoidon suunnittelussa ja seurannassa. Kuormituskokeen keskeisin etu on sen helppo saatavuus sekä avoterveydenhuollossa että erikoissairaanhoidossa. Rasitukseen liittyvien oireiden tai suorituskyvyn heikkenemisen yhteydessä kuormituskoe on edelleen arvokas perustutkimus. Sen käytön keskeisin rajoite liittyy sen diagnostiseen osuvuuteen, ja sepelvaltimotaudin ali- ja ylidiagnostiikan välttämiseksi kuormituskokeen käyttö tulisikin rajata liikuntakykyisiin potilaisiin, joilla taudin todennäköisyys ennen testiä on keskisuuri tai suuri. Kuormituskoe sopii potilaille, joiden lepo-EKG…

Heart rate and other risk factors in outpatients with stable coronary artery disease in Latvia

2011

Heart rate and other risk factors in outpatients with stable coronary artery disease in Latvia The aim of the study was to characterise coronary artery disease (CAD) outpatients in Latvia by risk factors (RF) including heart rate (HR), physical examination data, clinical data and treatment. Twelve practitioners had each examined and questioned 6 to 12 patients with established CAD (n = 120). The most frequent cardiovascular (CV) RF and co-morbidity were dyslipidemia (94.2%) and hypertension (78.3%), respectively. Prevalence of increased resting HR (≥70 bpm) was 35.9% and 33.6%, when measured by pulse palpation and electrocardiography, respectively. Regarding other RFs, prevalence of treated…

Sex differences in correlates of intermediate phenotypes and prevalent cardiovascular disease in the general population

2015

Background: There are marked sex differences in cardiovascular disease (CVD) manifestation. It is largely unknown how the distribution of CVD risk factors or intermediate phenotypes explain sex-specific differences. Methods and Results: In 5000 individuals of the population-based Gutenberg Health Study, mean age 55 ± 11 years, 51% males, we examined sex-specific associations of classical CVD risk factors with intima-media thickness, ankle-brachial index, flow-mediated dilation, peripheral arterial tonometry, echocardiographic, and electrocardiographic variables. Intermediate cardiovascular phenotypes were related to prevalent CVD [coronary artery disease, heart failure, stroke, myocardial i…
