Abstract The purpose of this prospective, clinical longitudinal survey was to describe, explain and understand the subjective quality of life and life course of patients with coronary artery disease. The study subjects' quality of life was assessed at the time of the onset of coronary artery disease, during the treatment process and during rehabilitation. Altogether 280 patients participated, of whom 80 were treated with medication, 100 with transluminal angioplasty, and 100 with bypass surgery. The study population consisted of 189 men and 91 women. At the baseline, the study subjects' self-care agency was measured with the Self-As-Carer Inventory (SCI). The subjects health-related quality of life was assessed with the Nottingham Health Profile (NHP) at the baseline as well as at 6 and 12 months after the procedure. The qualify of life of coronary artery disease patients was compared to the quality of life of an age- and sex-matched Finnish adult population (N = 3600) by using a previous standardisation of the NHP instrument. One year after the treatment, 19 patients who had undergone either bypass surgery or angioplasty attended thematic interviews at their homes. Triangulation of methodologies, methods and data collection was used in the study. The qualitative analysis of personal experiences was carried out using the method of phenomenological psychology described by Amedeo Giorgi based on Husserl's descriptive phenomenology. Before the treatment procedures, the quality of life of the coronary artery disease patients was significantly poorer than that of the age-matched adult population on the dimensions of energy, pain, emotional reactions, sleep and mobility. Moreover, the female patients with coronary artery disease had poorer health-related quality of life than the corresponding male patients, especially on the dimensions of energy, sleep, emotional reactions and mobility. The quality of life of the patients who had undergone angioplasty or bypass surgery was statistically significantly better one year after surgery on the dimensions of energy, pain and mobility. Their quality of life had, however, deteriorated on the dimensions of emotional reactions and social isolation. The thematic interviews revealed two kinds of life course: one with an active attitude towards treatment and a re-orientation of life course and another with a passive attitude towards treatment and a maintenance of the old principles in one's life course. A need for rehabilitation was indicated by an onset of the illness suddenly at a relatively young age, termination of an active working career, financial problems, dissatisfaction with the outcome of treatment, problems in family relations, and a desolate view of the future. An increased need for psychosocial support was especially common among women, subjects with recurrence and both male and female subjects in the youngest age group. According to the subjects, after-care failed to meet their needs or to address their problems. No continuous and confidential therapeutic relationships emerged. The problems included inadequate knowledge of one's condition and a lack of detailed instructions concerning the permissible degree of exertion after treatment. The patients felt they needed rehabilitation groups with coronary artery disease patients similar to themselves. The study yielded new knowledge about the health-related quality of life of coronary artery disease patients, the connections between the treatment methods and the changes in the patients' quality of life during one year and the patients' experiences at the time of the diagnosis and during the periods of treatment and after-care. This evidence-based knowledge can be used to develop the treatment and rehabilitation of coronary artery disease patients and to plan further research.

The educational medium GetWellNetWork (GWNW) in a large magnet teaching facility offered few educational videos specific to vascular patients with a focus on leg elevation after lower extremity bypass surgery. Supplying patient-specific education has the potential for providing cost-effective nursing care to vascular patients and improving hospital reimbursement. Guided by the interactive care model, a storyboard was developed using best-practice evidence for vascular postoperative patients that could lead to the development of a video to address the educational needs of vascular patients upon discharge. The practice focused question asked if a video addressing the importance of leg elevation would improve patients’ use of in-house educational videos and stakeholder satisfaction. A vascular physician (n = 1) and nursing staff (n = 9) provided feedback on the appropriateness of the evidence-based educational content for the storyboard by completing a 9-item, open-ended survey. Survey results supported development of the video and revealed positive feedback on storyboard content and that staff with 1–3 years’ experience or 15+ years’ experience had an increased understanding of the importance of evidence-based guidelines for leg elevation for vascular patients. The feedback will be used to develop a vascular-patient-specific educational video. Encouraging patients to view the video on leg elevation has the potential to improve cost effectiveness of patient care and hospital reimbursement, prevent hospital readmission that could lead to patient and caregiver hardships associated with readmission, and improve the health outcomes for postoperative vascular patients.

<p> Meta-analysis is a statistical method to summarize the overall evidence of effects on intervention by systematically combining outcomes from available studies in the literature which are homogeneous in research methodology and research interest. The objective of this project is to evaluate the treatment effects of preoperative aspirin on bleeding and other cardiovascular outcomes from 11 randomized control trials (RCT) and 19 observational (non-RCT) studies. Both Bayesian meta-analysis and classical (frequentist) meta-analysis were applied to continuous and binary outcomes, and the results were compared.</p> <p> The robustness of the Bayesian approach is assessed by examining the performances of different likelihood functions and priors. We also discuss strategies on dealing with zero-event studies for binary outcomes, and the implementation of multiple imputation (MI) technique to missing data for continuous outcomes.</p> <p> Most results of primary analysis agree between the Bayesian and classical approaches. We suggest that the final conclusion of a meta-analysis should be based on the comparison of the results from both Bayesian and classical approaches.</p> / Thesis / Master of Science (MSc)

OBJECTIVES The aim of this analysis was to assess the 7-year long-term safety and effectiveness of a randomized comparison of percutaneous coronary intervention (PCI) with sirolimus-eluting stents (SES) versus minimally invasive direct coronary artery bypass (MIDCAB) surgery for the treatment of isolated proximal left anterior descending lesions. BACKGROUND Long-term follow-up data comparing PCI by SES and MIDCAB surgery for isolated proximal left anterior descending lesions are sparse. METHODS Patients were randomized either to PCI with SES (n ¼ 65) or MIDCAB (n ¼ 65). Follow-up data were obtained after 7 years with respect to the primary composite endpoint of death, myocardial infarction, and target vessel revas- cularization. Angina was assessed by the Canadian Cardiovascular Society classification and quality of life with Short Form 36 and MacNew quality of life questionnaires. RESULTS Follow-up was conducted in 129 patients at a median time of 7.3 years (interquartile range: 5.7, 8.3). There were no significant differences in the incidence of the primary composite endpoint between groups (22% PCI vs. 12% MIDCAB; p ¼ 0.17) or the endpoints death (14% vs. 17%; p ¼ 0.81) and myocardial infarction (6% vs. 9%, p ¼ 0.74). However, the target vessel revascularization rate was higher in the PCI group (20% vs. 1.5%; p < 0.001). Clinical symptoms and quality of life improved significantly from baseline with both interventions and were similar in magnitude between groups. CONCLUSIONS At 7-year follow-up, PCI by SES and MIDCAB in isolated proximal left anterior descending lesions yielded similar long-term outcomes regarding the primary composite clinical endpoint and quality of life. Target vessel revascularization was more frequent in the PCI group.

INTRODUÇÃO: A ecocardiografia com perfusão miocárdica em tempo real (EPMTR) é uma técnica que permite a avaliação da perfusão miocárdica e a quantificação do fluxo miocárdico regional. Existem poucos dados na literatura a respeito da acurácia da EPMTR na detecção de viabilidade miocárdica e predição da melhora da qualidade de vida proporcionada pela revascularização miocárdica. MÉTODOS: Vinte e quatro pacientes com doença arterial coronária e disfunção ventricular esquerda crônica foram submetidos à EPMTR e questionário de qualidade de vida antes e após revascularização miocárdica. EPMTR foi realizada com injeção intravenosa contínua de PESDA ou Definity® e energia modulada. Recuperação funcional regional foi considerada padrão de referência (miocárdio hibernante), viabilidade miocárdica foi definida como presença de perfusão homogênea em pelo menos 1 segmento miocárdico no território revascularizado à avaliação qualitativa e a análise do fluxo miocárdico foi realizada nos 17 segmentos do ventrículo esquerdo obtendo-se índices de volume de sangue no miocárdio (A), da velocidade do fluxo () e do fluxo miocárdico absoluto (Ax) na condição de repouso no pré-operatório. Todos territórios revascularizados foram analisáveis. RESULTADOS: Presença de miocárdio hibernante foi observada em 77% dos territórios com viabilidade miocárdica pela EPMTR e em 44% dos territórios sem viabilidade (p=0,03). A presença de viabilidade pela EPMTR qualitativa apresentou sensibilidade, especificidade, valor preditivo positivo (VPP) e valor preditivo negativo (VPN) de 74%, 60%, 77% e 56%, respectivamente. Análise combinada (reserva contrátil e/ou perfusão miocárdica) resultou sensibilidade, especificidade, VPP e VPN de 89%, 40%, 73% e 67%, respectivamente. O valor de Ax 1,76 conferiu sensibilidade de 91,3%, especificidade de 50%, VPP de 75% e VPN de 77,8%, resultando em uma acurácia de 75,7%. O escore de qualidade de vida foi de 36,4 (29,1-43,6) para 18,1 (12,8-23,4; p =0,001) no pós-operatório. Entretanto, não houve correlação estatística com análise de perfusão miocárdica.CONCLUSÃO: Concluímos que a avaliação da perfusão miocárdica pela EPMTR apresenta boa acurácia para detecção de miocárdio hibernante em pacientes com DAC crônica e DVE. A presença de miocárdio viável pela EPMTR não foi capaz de prever a melhora da qualidade de vida após a cirurgia de revascularização miocárdica / BACKGROUND: Real-time perfusion echocardiography (RTPE) is an emerging modality for assessing myocardial perfusion and allows noninvasive quantification of regional myocardial blood flow. Little is known about the accuracy of the RTPE for the assessment of myocardial viability and the possibility of prediction of quality of life improvement after myocardial revascularization. METHODS: Twenty four patients with coronary artery disease and ventricular dysfunction underwent RTPE and answered Minnesota Quality of Life Questionnaire before and repeated after myocardial bypass coronary surgery. RTPE was performed using continuous PESDA or Definity intravenous infusion with power modulation image. Regional function recovery after surgical procedure was considered the standard reference (hibernating myocardial). Qualitatively, viability was defined as presence of homogeneous opacification in at least one myocardial segment in a rest revascularized territory, according coronary distribution. For myocardial blood flow evaluation, the left ventricle was divided into 17 segments, and indexes of myocardial blood volume (A), blood flow velocity (), and myocardial blood flow (Ax) were obtained for each myocardial segment at rest condition. All revascularized territories were analyzed. RESULTS: Hibernating myocardial was observed in 77% of RTPE viable territories and in 44% in non-viable ones (p=0.03). Sensitivity, specificity, predictive positive and negative values of qualitative RTPE viability detecting were 74%, 60%, 77% and 56%, respectively. A combined analysis (contractile reserve and/or myocardial perfusion) provided sensitivity, specificity, predictive positive and negative values of 89%, 40%, 73% e 67%, respectively. The sensitivity, specificity, predictive positive and negative values of Ax1.76 for recovery of function were 91%, 50%, 75% and 78%, respectively, with an accuracy of 76%. Quality of life score improved from 36.4 (29.1-43.6) to 18.1 (12.8-23.4; p =0.001). However, there was no statistical correlation with RTPE. CONCLUSION: In conclusion, RTPE provides good accuracy of detecting hibernating myocardial in patients with coronary artery disease and ventricular dysfunction. Nevertheless, it couldnt predict the quality of life improvement after myocardial revascularization

Dagens samhälle kräver att varje enskild individ måste ta beslut över alla de val som vi ställs inför. När det gäller val som antingen gynnar eller missgynnar vår hälsa är möjligheterna idag oändliga. På grund av detta finns det många som ökar i vikt och därmed kan behöva hjälp med att göra en livsstilsförändring. Syftet med denna studie var att undersöka vilka faktorer som kan ha påverkat och motiverat i valet av att göra en gastric bypass operation, samt att urskilja vilka förändringar som följer efter den typen av livsstilsförändring. Semistrukturerade intervjuer genomfördes där fyra informanter deltog och studiens data analyserades med en kvalitativ innehållsanalys. Resultatet skrevs fram med tre huvudkategorier: Livet innan operationen, Faktorer som påverkat och motiverat till att välja gastric bypass samt Livet efter operationen. Detta visade att informanterna motiverades av deras oro inför den framtida hälsan samt deras förhoppningar om en förändrad framtid, det visade också att deras val påverkades av omgivningen. Sinnesstämningen och den sociala tillhörigheten hade förbättrats efter operationen och livskvaliteten hade ökat. / Today's society requires that each individual has to take decisions on all the choices that we face. When it comes to choices that either benefit or disadvantage our health the possibilities are endless. As a result of this there is a large part of the population that has increased in weight and might need help in making lifestyle changes. The purpose of this study was to investigate the factors that may have influenced and motivated the choice of going through a gastric bypass surgery, and to discern which changes following that kind of lifestyle change. Semi-structured interviews with the four participants were conducted, data were analyzed using qualitative content analysis. The result was partitioned into three main categories: Life before surgery, Factors that influenced and motivated to choose gastric bypass and Life after surgery. The findings displayed that the participants were motivated by their concern for the future health and their hopes for a changed future, the findings also showed that their choice was influenced by the surroundings. The surgery led to an improvement in mood and social life as well as an increase in quality of life for the participants.
