Avaliação do estado de saúde percebido e do impacto da insuficiência cardíaca por pacientes em seguimento ambulatorial / Assessment of the perceived health condition and the impact of heart failure by outpatients

Pelegrino, Viviane Martinelli 15 May 2008 (has links)
A Insuficiência Cardíaca (IC) é uma doença crônica e incapacitante de alta morbi-mortalidade que provoca mudanças na qualidade de vida relacionadas à saúde (QVRS). Foi realizado um estudo descritivo, correlacional tipo corte transversal com 138 pacientes com IC em seguimento ambulatorial com os objetivos de avaliar: o estado geral de saúde por meio do Medical Outcomes Survey 36 - Item Short-Form (SF-36), o impacto da IC na vida diária utilizando o Minnesota Living with Heart Failure Questionnaire (MLHFQ) e analisar as relações entre essas duas variáveis e do estado de saúde percebido e do impacto da IC com variáveis sócio-demográficas e clínicas. Os dados foram coletados por entrevistas e, posteriormente, processados e analisados por meio de estatística descritiva, teste de correlação de Pearson, teste t e ANOVA para comparação entre os grupos e análise da consistência interna dos instrumentos usados (? de Cronbach). O nível de significância foi de 0,05. Como resultados constatamos que a maioria dos pacientes era do sexo masculino, com idade média de 56 anos, casados, baixa escolaridade e aposentados com renda média mensal individual de dois salários mínimos. Clinicamente, apresentaram IC secundária à miocardiopatia Dilatada Idiopática seguida da miocardiopatia Chagásica com classe funcional (CF-NYHA) II e III, grave disfunção sistólica, ou seja, menor valor da fração de ejeção do ventrículo esquerdo (FEVE) e com outras doenças associadas. Os instrumentos apresentaram, em sua maioria, consistência interna satisfatória (0,44 a 0,88 para o SF-36 e 0,78 a 0,93 para o total do MLHFQ e suas dimensões). A avaliação dos valores do SF-36 pode variar de zero a 100 com maiores valores indicando melhor estado de saúde percebido enquanto a avaliação dos valores do MLHFQ varia de zero a 105 com maiores valores indicando maior impacto da IC na vida diária dos pacientes. Os resultados foram apresentados em média e desvio-padrão. Os componentes mais comprometidos do SF-36 foram os Aspectos físicos (36,8+41,2) e Aspectos emocionais (47,6+43,9). O MLHFQ obteve valor de 35,8 (+24,9) para o total, 13,6 (+11,5) para dimensão física e 8,3 (+6,7) para a emocional. A correlação entre os instrumentos foi de forte magnitude e todas estatisticamente significantes. O impacto da IC na vida das mulheres (41,2+24,3) foi maior que os homens (32,2+24,9). A correlação entre o MLHFQ e idade e tempo de seguimento ambulatorial apresentou-se negativa e fraca, mas estatisticamente significante apenas para o tempo. As correlações do MLHFQ total e as variáveis clínicas foram estatisticamente significantes. O impacto da IC tende a aumentar com menor FEVE e maior CF-NYHA. O estado de saúde percebido e o impacto da IC na vida diária estavam moderadamente comprometidos. Quanto pior a percepção sobre o estado geral de saúde mais os pacientes com IC sentem o impacto dessa condição crônica de saúde sobre sua vida diária. Os pacientes com IC apresentaram comprometimento no seu estado de saúde percebido e sofreram com o impacto dessa doença em suas vidas diárias afetando a qualidade de vida. Mensurar a qualidade de vida relacionada à saúde permite a identificação de aspectos relevantes percebido pelos pacientes. A utilização dessas medidas, ou seja, o estado de saúde percebido e o impacto da IC na vida diária tornam-se uma ferramenta na identificação desses aspectos. Os resultados advindos dessas medidas poderão ser usados para subsidiar a assistência à saúde desses pacientes. / Heart Failure (HF) is a chronic and debilitating condition of high morbidity and mortality that provokes changes in the health related quality of life (HRQL). A descriptive, correlational study type transversal cut with 138 outpatients with HF was performed with the objectives of assessing the general health condition by Medical Outcomes Survey 36 - Item Short-Form (SF-36), the impact of HF in daily life using the Minnesota Living with Heart Failure Questionnaire (MLHFQ) and analyzing the relations between these two variables and the perceived health condition and the impact of HF with socio-demographic and clinical variables. The data were collected through interviews and, subsequently, processed and analyzed by descriptive statistics, test on Pearson\'s correlation, t-test and ANOVA for comparison among the groups and analyses of internal consistency of the used instruments (Cronbach\'s ). The level of significance was 0,05. It was found that the most patients were men, average age 56 years old, married, low rate of literacy and retired with two minimum wages as individual monthly minimum revenue. Clinically, they presented HF secondary to Idiopathic Dilated myocardiopathy followed by Chagas\' myocardiopathy with functional class (CF-NYHA) II and III, serious systolic dysfunction, in other words, decreased value of left ventricular ejection fraction (LVEF) and with other related diseases. The instruments presented, mostly, satisfactory internal consistency (0,44 to 0,88 for SF-36 and 0,78 to 0,93 for the total MLHFQ and its dimensions). The assessment of the values of SF-36 may vary from zero to 100 with increased values indicating better perceived health condition and the MLHFQ assessment varies from zero to 105 with increased values indicating greater impact on daily patient\'s life. The results were presented in means and standard deviation. The most impaired components of SF-36 were the physical (36,8+41,2) and emotional (47,6+43,9) aspects. The MLHFQ achieved the value 35,8 (+24,9) for the total; 13,6 (+11,5) for the physical dimension and 8,3 (+6,7) for the emotional dimension. The correlation among instruments had a strong importance and all were statistically significant. The impact of HF on women\'s lives (41,2+24,3) was more severe than on men\'s (32,2+24,9). The correlation among the MLHFQ, the age and time in an outpatient clinic was presented as negative and weak, but statistically significant only for the time. The total and clinical variables correlations of MLHFQ were statistically significant. The impact of HF tends to increase with decreased LVEF and increased CF-NYHA. The general perceived health condition and the impact of HF on daily life were reasonably impaired. The more the perception on the general health condition the more the patients with HF feel the impact of this chronic health condition on their daily life. It is more common in young women patients with decreased time in outpatient clinic and whose condition was more severe related to the systolic dysfunction and to the symptoms. These patients need greater attention from the health team during the outpatient clinical care, especially in the onset of the medical assistance.

Uso de cateter central de inserção periférica para redução da incidência de flebite relacionada a acesso venoso durante a infusão de inotrópico em pacientes com insuficiência cardíaca descompensada: ensaio clínico randomizado / Peripherally inserted central catheters reduce the incidence of phlebitis in heart failure patients receiving prolonged intravenous inotropic infusions: a randomized trial

Silva, Eunice Vieira Cavalcante 28 November 2016 (has links)
Fundamento: Na descompensação da insuficiência cardíaca, pode ocorrer o baixo débito cardíaco, nessa situação o uso de inotrópico pode ser necessário. Se o acesso venoso for periférico, a infusão venosa prolongada de inotrópicos pode levar à flebite. Por outro lado, o acesso venoso central pode apresentar complicações. O Cateter Central de Inserção Periférica (PICC) pode ser uma opção nessa situação. O objetivo do presente estudo foi avaliar a incidência de flebite com o uso do PICC em comparação ao acesso venoso periférico. Métodos: em estudo clínico randomizado foram selecionados pacientes com insuficiência cardíaca congestiva avançada, em uso de inotrópico endovenoso; plaquetas >= 50.000/mm3 e fração de ejeção do ventrículo esquerdo (FEVE) < 0,45. Os pacientes foram randomizados para receberem o PICC ou manter o acesso venoso periférico. O desfecho principal foi à ocorrência de flebite. Os dados foram analisados pela regressão logística. Resultados: Foram incluídos 40 pacientes no Grupo PICC e 40 pacientes no grupo controle. A mediana da idade foi de 61,5 (IQR=16) anos, a FEVE foi de 24,0 (IQR= 10) % e a dose da dobutamina foi de 7,73 (IQR = 5,3) mcg/kg*min. No Grupo PICC a ocorrência de flebite foi de 2,5 % (1 paciente) enquanto no grupo controle foi de 95% (38 pacientes), com razão dos riscos (HR) de 0,1% (IC 95%: 0,0 a 1,6%, P < 0,001). Conclusões: O uso de PICC foi associado a redução da incidência de flebite durante a infusão endovenosa contínua de dobutamina em pacientes com baixo débito cardíaco durante internação por insuficiência cardíaca descompensada / Background: During decompensated heart failure, the use of intravenous inotropes can be necessary. With peripheral venous access, prolonged infusions can cause phlebitis. However, traditional central venous catheters have possible complications. Peripherally inserted central catheters (PICCs) may be an alternative to traditional catheters. Our objective was to compare the incidence of phlebitis between PICCs and catheters used to achieve peripheral venous access. Methods: In a randomized clinical trial, 40 patients were randomized to the PICC group and 40 patients were randomized to thecontrol group. The inclusion criteria were advanced heart failure, ejection fraction < 0.45, and platelets > 50,000/mm3. The patients were randomly assigned to receivea PICC or keep their peripheral venous access. The primary endpoint was the occurrence of phlebitis. Results: We included 40 patients in the PICC group and 40 patients in the control group. The median age was 61.5 (interquartile range [IQR]=16) years, the ejection fraction was 0.24 (IQR=0.10), and the dobutamine dose was 7.73 (IQR=5.3) mcg/kg*min. Phlebitis occurred in 1 patient (2.5%) in the PICC group and in 38 patients (95.0%) in the control group, with a hazard ratio of 0.1% (95% confidence interval [CI]: 0.0%-1.6%, P < 0.001). Conclusion: PICCs were associated with a lower incidence of phlebitis in patients hospitalized for decompensated heart failure with low cardiac output during intravenous dobutamine infusions

Cardiomiopatia dilatada em suínos no Brasil / Dilated cardiomyopathy in swine in Brazil

Cruz, Raquel Aparecida Sales da January 2017 (has links)
Cardiomiopatia dilatada (CMD) é uma doença miocárdica caracterizada por dilatação cardíaca e redução da contratilidade da parede do ventrículo esquerdo ou de ambos os ventrículos, sendo a etiologia de origem genética ou desconhecida. Em suínos existem raros relatos de CMD, sendo frequentemente relacionados com intoxicações por ionóforos ou gossipol. Surtos de CMD de etiologia desconhecida em suínos de rebanhos comerciais no Brasil sugeriram a existência de nova etiologia, possivelmente nutricional. Este estudo teve como objetivo investigar as possíveis causas dos surtos de CMD em suínos, a partir de análises macroscópicas, microscópicas, bioquímicas, cromatográficas, moleculares, imuno-histoquímica (IHQ) e reprodução experimental. E teve como resultado 2 artigos científicos. O primeiro artigo descreve os achados clínicos, patológicos, químicos e toxicológicos de três surtos de CMD em suínos de crescimento, além da reprodução experimental desta condição utilizando a ração de uma das propriedades afetadas. Para o estudo experimental utilizou-se 9 animais divididos em 3 grupo; Grupo 1 recebendo ração suspeita, Grupo 2 metade ração suspeita mais metade de ração controle e o grupo 3 recebeu ração controle. Dois suínos do grupo 1 apresentaram condições clínicas e patológicas semelhantes aos casos naturais após 8 dias de consumo da ração suspeita. Os principais sinais clínicos observados eram tosse e dispneia grave. Na necropsia foram constatados dilatação cardíaca bilateral acentuada, hidrotórax, hidropericárdio, edema pulmonar, ascite e fígado com aspecto de noz moscada. O segundo artigo teve como objetivo fazer a caracterização histológica, histoquímica e imuno-histoquímica das lesões cardíacas em 8 suínos com CMD e compara-las com dois suínos controles. As principais lesões evidenciadas foram atrofia de cardiomiócitos, vacuolização sarcoplasmática, ruptura de miofibras e fibras com padrão ondulado evidenciadas nas colorações de hematoxilina e eosina (HE), Tricrômico de Masson e Picrosírius. Na análise imuno-histoquímica utilizando o anticorpo anti-desmina houve uma imunomarcação reduzida ou inexistente em áreas com lesões histopatológicas. A imuno-histoquímica anti-desmina demonstrou ser uma importante ferramenta diagnóstica para caracterização de lesões de CMD em suínos. / Dilated cardiomyopathy (DCM) is a myocardial disease characterized by cardiac dilatation and reduced contractility of the left ventricular wall or both ventricles, the etiology of which is genetic or unknown. In pigs there are rare reports of DCM and are often related to ionosphere or gossypol poisoning. DCM outbreaks of unknown etiology in swine from herds in Brazil suggested the existence of a new, possibly nutritional, etiology. This study aimed to investigate the possible causes of DCM in pigs through macroscopic, microscopic, biochemical, chromatographical, molecular and immunohistochemical (IHC) evaluations, as well as the experimental reproduction of the disease. The project resulted in 2 scientific papers. The first article describes the clinical, pathological, chemical and toxicological findings of three DCM outbreaks in grower pigs, in addition to the experimental reproduction of this condition using the ration of one of the affected farms. For the experimental trial, 9 animals were divided into 3 groups; Group 1 received suspected ration only, Group 2 was fed a diet composed of half suspected ration plus half control ration, and group 3 received control ration only. Two pigs from group 1 presented clinical and pathological conditions similar to the natural cases after 8 days of consumption of the suspected ration. The main clinical signs observed were cough and severe dyspnea. At necropsy, bilateral cardiac dilatation, hydrothorax, hydropericardium, pulmonary edema, ascites and liver with the appearance of nutmeg were observed. The second article aimed to perform the histological, histochemical and immunohistochemical characterization of the cardiac lesions in 8 pigs with DCM and compare it with two control pigs. The main lesions evidenced were cardiomyocyte atrophy, sarcoplasmic vacuolization, rupture of myofibers and fibers with corrugated pattern evidenced in the staining of hematoxylin and eosin (HE), Masson's trichrome (MT) and Picrosírius (PS). Immunohistochemistry analysis using the anti-desmin antibody showed reduced or non-existent immunostaining in areas with histopathological lesions. The anti-desmin IHC proved to be an important tool for the diagnosis and characterization of DCM lesions in pigs.

No. of bitstreams: 1 Ysabely de Aguiar Pontes Pamplona.pdf: 2372319 bytes, checksum: 6ecd5cfeb943df20c4248a8c73344a04 (MD5) Previous issue date: 2016-03-28 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES / Although there are robust evidence on the effects of exposure to air pollution on cardiovascular disease, little has been studied about the modification of this relationship induced by age and sex. This study aims to evaluate the relationship between air pollution and hospital admissions for Congestive Heart Failure (CHF) in adults and elderly in the city of São Paulo, stratified by sex, exploiting gaps structures for the 2000-2013 period. This is an ecological time series study, which uses hospital admissions information obtained from the Brazilian Unified Database Health (DATASUS), information on the daily levels of PM10, SO2, O3, NO2, CO, minimum temperature and average relative humidity were obtained from the Environmental Agency of the State of São Paulo (CETESB). A descriptive analysis was performed and calculated the Pearson correlation coefficient. To assess the relationship between exposure to pollutants and the outcomes of interest was used linear polynomial models with generalized Poisson regression exploring lags structures of up to 7 days. The models were adjusted for short and long term, and weather variables seasonality. The significance level was 5%. Results showed that contaminants were directly correlated (p <0.001), and inversely correlated with weather variables (p < 0.001), except O3, which was directly correlated with temperature (p <0.001). For the increase of one interquartile (7.63¿g/m3) in the SO2 level among adults (45-60 years) was related to the increase in hospital admissions for CHF of 5.32% (CI95%: 5.29-5.36) for women and 7.75% (CI95%: 7.53-7.96) for men in the first two days after exposure. In the group of elderly (60 years old) this increase raised admissions for CHF in 6.69% (CI95%: 6.62-6.75) for women and 5.83% (CI95%: 5.75¿5.90) for men in the first two days after exposure. For PM10 in relation to adults (45-60 years) an increase of 24.28¿g/m3 increased hospitalizations for ICC in 11.38% (CI95%: 10.68-12.09) for women and 4.08% (CI95%: 4.04-4.12) for men in the first three days after exposure. In the group of elderly (60 years old) there was an increase of 6.92% (CI95%: 6.86-6.98) for women and 5.97% (CI95%: 5.90-6 04) for men in the first two days after exposure in hospitalizations for ICC. The adverse effects of SO2 on CHF admissions in adult were higher men than in women. However, in the elderly group the adverse effects of SO2 on CHF admissions were higher in the women's groups. As for PM10, women seem to be more susceptible than men due to the adverse effects of PM10 on admissions for CHF, especially in the younger age group. It is concluded that the effect of air pollutants in admissions for CHF differ by age and sex. / Apesar de haver evidências robustas sobre os efeitos da exposição à poluição do ar sobre as doenças cardiovasculares, pouco tem sido estudado sobre a modificação desta relação induzida pela faixa etária e pelo sexo. Este estudo tem por objetivo avaliar a relação entre poluição do ar e internações por Insuficiência Cardíaca Congestiva (ICC), em adultos e idosos, na cidade de São Paulo, estratificado por sexo, explorando estruturas de defasagens, para o período de 2000 a 2013. Este é um estudo ecológico de séries temporais, que utiliza informações de internações hospitalares obtidas junto ao banco de dados do Sistema Único de Saúde (DATASUS), as informações sobre os níveis diários de PM10, SO2, O3, NO2, CO, temperatura mínima e umidade relativa média foram obtidos junto a Agência Ambiental do Estado de São Paulo (CETESB). Foi realizada a análise descritiva e calculado o coeficiente de correlação de Pearson. Para se avaliar a relação entre exposição a poluentes e os desfechos de interesse foi utilizado modelos polinomiais lineares generalizados de regressão de Poisson explorando estruturas de defasagens de até 7 dias. Os modelos foram ajustados para sazonalidade de curta e longa duração e pelas variáveis meteorológicas. O nível de significância foi de 5%. Os poluentes estavam diretamente correlacionados entre si (p<0,001) e inversamente correlacionada com variáveis meteorológicas (p<0,001), com exceção do O3, que foi diretamente correlacionada com a temperatura (p< 0,001). Para o aumento de um interquartil (7,63¿g/m3) no nível de SO2, entre os adultos (45-60 anos) esteve relacionado com o aumento nas admissões hospitalares por Insuficiência Cardíaca Congestiva de 5,32% (IC95%: 5,29 - 5,36) para mulheres e 7,75% (IC95%: 7,53 - 7,96) para os homens nos dois primeiros dias após a exposição. No grupo de idosos (60 ou mais anos de idade) esse aumento elevou as admissões por ICC em 6,69 % (IC95%: 6,62 - 6,75) para mulheres e 5,83 % (IC95%: 5,75 - 5, 90) para os homens nos dois primeiros dias após a exposição. Para PM10 em relação aos adultos (45-60 anos) um aumento de 24,28¿g/m3 elevou as internações por Insuficiência Cardíaca Congestiva em 11,38% (IC95%: 10,68 - 12,09) para mulheres e 4,08% (IC95 %: 4,04 - 4,12) para os homens nos três primeiros dias após a exposição. No grupo de idosos (60 ou mais anos de idade) observou-se um aumento de 6,92 % (IC95%: 6,86 - 6,98) para mulheres e 5,97% (IC95%: 5,90 - 6,04) para os homens nos dois primeiros dias após a exposição nas internações por Insuficiência Cardíaca Congestiva. Os efeitos adversos de SO2 sobre admissões de Insuficiência Cardíaca Congestiva foram maiores em homens adultos do que nas mulheres. No entanto, no grupo de idosos os efeitos adversos de SO2 sobre admissões de Insuficiência Cardíaca Congestiva foram maiores nos grupos de mulheres. Já para o PM10, as mulheres parecem ser mais suscetíveis do que os homens, devido aos efeitos adversos do PM10 sobre admissões por Insuficiência Cardíaca Congestiva, principalmente no grupo etário mais jovem. Conclui-se que o efeito dos poluentes do ar nas admissões por ICC diferem por faixa etária e sexo.

Walking Versus Jogging in Patients With Cardiac Problems Including Congestive Heart Failure

Garcia, Rosalie Roberta 01 January 2017 (has links)
Congestive heart failure (CHF) is a growing epidemic that affects more than 50% of the world's population. CHF is a preventable disease, but prevention requires a healthy lifestyle from a young age. Most patients already diagnosed with CHF receive advice and strict instructions for care to prevent further cardiac injury. This quantitative descriptive research study was designed to address walking and jogging as the best exercises for patients diagnosed with CHF and in patients diagnosed with other cardiac problems. The results revealed that walking is the best exercise to improve patients' resting heart rate and overall cardiac function. This study also indicated that cardiac rehabilitation (CR) improved both blood pressure and heart rate, but the findings showed that CR improved heart rate most effectively. The Levine conservation model served as the foundation of the research. The Levine conservation model ensures the safety and the wholeness of a patient by protecting the interaction and adaptations of the patient's health care plan and environment through conserving and balancing energy. The social change plan for this research study is to give health care teams who care for patients with CHF or cardiac problems guidance to educate patients about CR. Increasing CR education among all health care teams could help improve many patients' quality of life, and the autonomy and empowerment given to patients may subsequently increase patients' cooperation with the treatment plan.

Telehealth: Improving Quality of Life in Veterans with Congestive Heart Failure

Callender, Marcia Callender 01 January 2016 (has links)
Congestive heart failure (CHF) affects an estimated 5.1 million Americans over the age of 20. The purpose of this quantitative study was to determine whether there is a difference in the Quality of Life (QOL) for Congestive heart failure patients receiving care through telehealth compared to patients receiving face-to-face care (usual care). Guiding this project was the Self-Care Model of Chronic Illness because the primary outcome of the self-care model is illness stability, well-being, and quality of life. Seventy-seven veterans with Heart Failure (HF) from the Washington D.C. Veterans Affairs Medical Center (VAMC) participated in the project. Forty reported they were receiving telehealth and 37 reported that they were receiving face-to-face care. The average participant age was 67 years with a range of 44 to 93 years. Seventy-five of the participants were male and 2 were female. Sixty-four participants were Black and 12 were White. The Minnesota Living with Heart Failure (MLHF) questionnaire average score for the telehealth group was 49.4 (SD = 28.7) and the face-to-face care group was 37 (SD = 27.9). With equal variance assumed, there was no significant difference between MLHF scores in the telehealth group compared to the usual care group (t = -1.91, p > .05). Thus, opportunities for using telehealth without negatively affecting patient outcomes, such as QOL, are plausible. It can be concluded that providing services using home telehealth for HF patients may produce outcomes that are equivalent to those receiving traditional services.

The relationship between B-type natriuretic peptide levels and hospital length of stay and quality of life in congestive heart failure patients

Previous research on quality of life (QOL) and its relation to BNP levels in heart failure (HF) has been widely studied. However, the impact of physicians' knowledge of BNP levels at time of clinic visit on QOL and hospital length of stay (LOS) has yet to be fully investigated. The purpose of this study were to determine if physicians' knowledge of BNP levels affected a change in QOL scores at 90 days and reduce hospital length of stay among heart failure patients. QOL data from HF clinic patients (N = 108, 67.5 ± 12.3, 56% male, ejection fraction 26.5 ± 8.2) were analyzed. QOL was measured at time of clinic visit (T1) and at 90 days (T2) using the Minnesota Living with Heart Failure Questionnaire (MLHFQ). An independent t-test was utilized to compare the two groups. Findings: Both groups were comparable regarding demographic and baseline characteristics. There was no significant association observed between the experimental and control group at 90 days, although the data indicated a decrease in the mean QOL scores at 90 days (37.46 ± 28.67) as compared to the mean QOL scores at baseline (46.87 ± 29.63) for both groups. Because the QOL scale is reversed, this indicated that there was a positive change in QOL scores during the 90 day time interval. Hospital LOS was similar for both groups (mean=3 days). BNP levels were significantly correlated with both baseline QOL scores (r=.25, p=.01) and physical subscale scores (r=.24, p=.01). Mortality was higher in the control when compared to the experimental group (t=1.99, df=90, p=.04). Conclusion: While physicians' awareness of BNP levels had not shown a significant change in QOL at 90 days, patients' QOL might already have been quite positive. Chronic HF patients may have adapted to their disease and have adjusted their perception of their QOL. Therefore, QOL may be a stable construct at this time. Findings may have been different on newly diagnosed HF patients since they may not have adapted to their health condition.

CHARACTERIZATION OF THE ANGIOTENSIN TYPE 1 RECEPTOR AND THE BETA2 ADRENERGIC RECEPTOR PROPERTIES: THE INVOLVEMENT OF ARRESTIN2, RAB1 AND SOME MOLECULAR CHAPERONES IN THE ASSEMBLY AND TRAFFICKING OF GPCRS

Hammad, Maha 21 July 2010 (has links)
Current drugs used to treat Congestive Heart Failure target the renin-angiotensin and adrenergic systems. Studies showed increased mortality rates in patients treated with a combination of these medications. Angiotensin-AT1 and ?2-Adrenergic receptors were shown to form receptor heteromers. Blockade of one receptor in the complex can affect the signal transmitted by the other; suggesting that ligand-based therapy is not as selective as we might think. Modulating receptor trafficking after synthesis might prove to be a valid therapeutic strategy. Unfortunately, little is known about receptor assembly and transport from Endoplasmic Reticulum to Plasma Membrane. The objectives of this study are to identify the proteins that participate in the assembly of AT1R-?2AR heteromer and the regulators of the anterograde trafficking of G-Protein Coupled Receptors. This thesis introduces the role of important targets in those poorly understood processes. The identification of such targets could lead to developing better drugs with fewer adverse effects.
