RESUMO

This study explores healthcare professionals' experiences of using behavior change interventions in clinical practice. Semi-structured qualitative interviews were conducted with 11 healthcare professionals working in a cardiac and pulmonary rehabilitation National Health Service Trust in the United Kingdom. Interviews were transcribed and analyzed using inductive thematic analysis. Four overarching themes representing healthcare practitioners' perceptions of using behavior change interventions were identified: (1) reliance on experiential learning, (2) knowledge transition, (3) existing professional development programs, and (4) barriers and facilitators for continued professional development. The results are discussed in relation to the implications they may have for behavior change training in clinical healthcare practice. Healthcare professionals require bespoke and formalized training to optimize their delivery of behavior change interventions in cardiac and pulmonary rehabilitation. Doing so will enhance intervention fidelity and implementation that can potentially ameliorate patient rehabilitation outcomes.

RESUMO

OBJECTIVE: To examine the effects of a consultant-led, community-based chronic obstructive pulmonary disease (COPD) service, based in a highly deprived area on emergency hospital admissions. DESIGN: A longitudinal matched controlled study using difference-in-differences analysis to compare the change in outcomes in the intervention population to a matched comparison population, 5 years before and after implementation. SETTING: A deprived district in the North West of England between 2005 and 2016. INTERVENTION: A community-based, consultant-led COPD service providing diagnostics, treatment and rehabilitation from 2011 to 2016. MAIN OUTCOME MEASURES: Emergency hospital admissions, length of stay per emergency admission and emergency readmissions for COPD. RESULTS: The intervention was associated with 24 fewer emergency COPD admissions per 100 000 population per year (95% CI -10.6 to 58.8, p=0.17) in the postintervention period, relative to the control group. There were significantly fewer emergency admissions in populations with medium levels of deprivation (64 per 100 000 per year; 95% CI 1.8 to 126.9) and among men (60 per 100 000 per year; 95% CI 12.3 to 107.3). CONCLUSION: We found limited evidence that the service reduced emergency hospital admissions, after an initial decline the effect was not sustained. The service, however, may have been more effective in some subgroups.

RESUMO

OBJECTIVE: To examine the effects on emergency hospital admissions, length of stay and emergency re-admissions of providing a consultant-led, community-based cardiovascular diagnostic, treatment and rehabilitation service, based in a highly deprived area in the North West of England. METHODS: A longitudinal matched controlled study using difference-in-differences analysis compared the change in outcomes in the intervention population, to the change in outcomes in a matched comparison population that had not received the intervention, 5 years before and after implementation. The outcomes were emergency hospitalisations, length of inpatient stay and re-admission rates for cardiovascular disease (CVD). RESULTS: Findings show that the intervention was associated with 66 fewer emergency CVD admissions per 100 000 population per year (95% CI 22.13 to 108.98) in the post-intervention period, relative to the control group. No significant measurable effects on length of stay or emergency re-admission rates were observed. CONCLUSION: This consultant-led, community-based cardiovascular diagnostic, treatment and rehabilitation service was associated with a lower rate of emergency hospital admissions in a highly disadvantaged population. Similar approaches could be an effective component of strategies to reduce unplanned hospital admissions.

RESUMO

BACKGROUND: Left ventricular hypertrophy and myocardial remodeling occur with aortic valve disease and may lead to heart failure. Although increased oxidative stress and inflammatory factors have been implicated in heart failure, their role in the progression of valve disease remains unclear. OBJECTIVES: We investigated the role of oxidative stress and inflammatory factors in valve disease whether this relates to cell death. METHODS: Blood samples were taken from 24 patients with valve disease before surgery and the results were compared with those from blood samples from 30 control healthy subjects. Myocardial biopsies from patients with valve disease were also collected before cannulation of the right atrial appendage. NF-κB activities in atrial and mononuclear cells nuclear extracts were determined by electrophoretic mobility shift assay. RESULTS: Nuclear factor kappaB activities were significantly greater in mononuclear cells from AVD patients compared with healthy controls and the antigens were detectable in atrial tissues valve disease patients. Plasma C-reactive protein, B-natriuretic peptides, plasma tumor necrosis factor alpha and soluble tumor necrosis factor receptor 1 and 3-nitrotyrosine levels were significantly higher in valve disease patients. Inducible nitric oxide and 3-nitrotyrosine antigens and cells expressing CD45 antigens were detected within atrial tissues obtained from valve disease patients suggesting oxidative stress originated from in situ leukocytes. CONCLUSION: The findings suggest that oxidative stress originating from in situ leukocytes within the atrial myocardium may be the potential trigger for excessive transcriptional activities and apoptotic cell death within the atrial myocardium of valve disease patients. This represents a potential therapeutic target.

RESUMO

ABSTRACT Objective: To evaluate different weight loss (WL) cut-off points as prognostic markers of 3-month survival after diagnosis of stage IV non-small cell lung cancer (NSCLC). Methods: This was a prospective study involving 104 patients with metastatic (stage IV) NSCLC who were admitted to a cancer treatment center in southern Brazil between January of 2014 and November of 2016. We evaluated total WL and WL per month, as well as WL and WL per month in the 6 months preceding the diagnosis. The patients were followed for 3 months after diagnosis. A Cox proportional hazards regression model and Kaplan-Meier curves were used in order to evaluate 3-month survival. Results: The median WL in the 6 months preceding the diagnosis was 6% (interquartile range, 0.0-12.9%). Patients with WL ≥ 5% had a median survival of 78 days, compared with 85 days for those with WL < 5% (p = 0.047). Survival at 3 months was 72% for the patients with WL ≥ 5% (p = 0.047), 61% for those with WL ≥ 10% (p < 0.001), and 45% for those with WL ≥ 15% (p < 0.001). In the multivariate analysis, the hazard ratio for risk of death was 4.51 (95% CI: 1.32-15.39) for the patients with WL ≥ 5%, 6.34 (95% CI: 2.31-17.40) for those with WL ≥ 10%, and 14.17 (95% CI: 5.06-39.65) for those with WL ≥ 15%. Conclusions: WL in the 6 months preceding the diagnosis of NSCLC is a relevant prognostic factor and appears to be directly proportional to the rate of survival at 3 months.


RESUMO Objetivo: Avaliar diferentes pontos de corte da perda de peso (PP) como marcadores prognósticos de sobrevida em 3 meses após o diagnóstico de câncer de pulmão de células não pequenas estádio IV (CPCNP). Métodos: Estudo prospectivo envolvendo 104 pacientes com CPCNP metastático (estádio IV) que foram internados em um centro de tratamento de câncer no sul do Brasil entre janeiro de 2014 e novembro de 2016. Avaliamos a PP total e PP por mês, bem como PP e PP por mês nos 6 meses anteriores ao diagnóstico. Os pacientes foram acompanhados por 3 meses após o diagnóstico. Um modelo de regressão de riscos proporcionais de Cox e curvas de Kaplan-Meier foram utilizados para avaliar a sobrevida em 3 meses. Resultados: A mediana da PP nos 6 meses anteriores ao diagnóstico foi de 6% (intervalo interquartil, 0,0-12,9%). Pacientes com PP ≥ 5% tiveram uma sobrevida mediana de 78 dias, comparados a 85 dias para aqueles com PP < 5% (p = 0,047). A sobrevida em 3 meses foi de 72% para os pacientes com PP ≥ 5% (p = 0,047), 61% para aqueles com PP ≥ 10% (p < 0,001) e 45% para aqueles com PP ≥ 15% (p < 0,001). Na análise multivariada, a taxa de risco para óbito foi de 4,51 (IC95%: 1,32-15,39) para os pacientes com PP ≥ 5%, 6,34 (IC95%: 2,31-17,40) para aqueles com PP ≥ 10%, e 14,17 (IC95%: 5,06-39,65) para aqueles com PP ≥ 15%. Conclusões: A PP nos 6 meses anteriores ao diagnóstico de CPCNP é um fator prognóstico relevante e parece ser diretamente proporcional à taxa de sobrevida em 3 meses.

RESUMO

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a degenerative condition that can impair health-related quality of life (HRQoL). A number of self-management interventions, employing a variety of behavioural change techniques (BCTs), have been adopted to improve HRQoL for COPD patients. However, a lack of attention has been given to group management interventions with an emphasis on incorporating BCTs into rehabilitators' practice. This study aims to pilot and feasibly explore a social identity group management intervention, delivered by COPD rehabilitation staff to patients attending exercise pulmonary rehabilitation. Doing so will help inform the plausibility of the intervention before conducting a full trial to evaluate its effectiveness to improve HRQoL. METHODS: This is a two-centre, randomised cross-over controlled trial. Two pulmonary rehabilitation centres based in the UK will be randomly allocated to two treatment arms (standard care and intervention). Outcome measurements relating to HRQoL and social identity will be completed pre- and post-exercise rehabilitation. Focus group interviews will be conducted at the end of exercise rehabilitation to capture participants' contextualised experiences of the intervention. COPD rehabilitators will undertake semi-structured interviews at the end of the trial to garner their holistic perspectives of intervention fidelity and implementation. DISCUSSION: This is the first study to adopt a social identity approach to develop a rehabilitator-led, group management intervention for COPD patients attending exercise pulmonary rehabilitation. The results of this study will provide evidence for the feasibility and sample size requirements to inform a larger study, which can ascertain the intervention's effectiveness for improving HRQoL for COPD patients. TRIAL REGISTRATION: ClinicalTrials.gov NCT02288039. Date 31 October 2014.

RESUMO

PURPOSE: This review provides an overview and quality assessment of existing interventions, assessing the intervention types that are most effective at increasing enrolment and adherence to cardiac rehabilitation in older patients aged ≥65 years Methods: The review of the literature was performed using electronic databases to search for randomised controlled trials that aimed to increase enrolment and/or adherence to cardiac rehabilitation in older patients aged ≥65 years. The main key words were cardiac rehabilitation, enrolment, adherence and older patients. Studies were included if; (1) the intervention targeted improving enrolment and/or adherence to at least one of the following components of the cardiac rehabilitation programme: exercise, education or maintaining lifestyle changes; (2) assess the effectiveness of an intervention on increasing enrolment and/or adherence to a cardiac rehabilitation programme or any of its components; (3) include measures for assessing enrolment and/or adherence to a cardiac rehabilitation programme or any of its components; (4) the study included patients with a mean age of ≥65 years who were deemed eligible to participate in a cardiac rehabilitation programme. Included studies could be published in any language and there were no date restrictions for included studies. Studies focusing on pharmaceutical adherence were not included for the purpose of this review. RESULTS: Seven studies were included, with four investigating enrolment (1944 participants) and three assessing adherence to intervention programmes (410 participants). Three studies (1919 participants) reported higher enrolment to cardiac rehabilitation in the intervention group. Two studies that reported increases in enrolment to cardiac rehabilitation were deemed to have an unclear or high risk of bias. All three studies (410 participants) reported better adherence to cardiac rehabilitation in the intervention group when compared to the control group. Two studies that reported better completion of cardiac rehabilitation were deemed to have an unclear or high risk of bias. No formal meta-analysis was conducted due to the observed multiple heterogeneity among outcome measures, the low number of included studies and variability in study designs. CONCLUSION: This review found only weak evidence to suggest that interventions can increase enrolment or adherence to cardiac rehabilitation programmes for patients aged ≥65 years, therefore no practice recommendations could be made and further high-quality research is needed in this population group.

RESUMO

OBJECTIVES: The aim of this study was to prove that one possible statin-related protective mechanism in dams and offspring fed a high-fat diet (HFD) is the reduction in cardiovascular risk and impairment of the vasculogenic element of endothelial regeneration. METHODS: To explore this, virgin C57 BL/6 mice (n = 8/group) were fed an HFD (fat: 45% kcal) or standard chow (C; fat: 21% kcal) from weaning and throughout their pregnancy and lactation. Half of the HFD group also was given the 3-hydroxy-3-methylglutaryl-coenzyme A reductase inhibitor pravastatin (S) through their drinking water (5 mg/kg body weight per day) to create HF+S dam group (n = 8/group). Offspring from each group were fed HFD or C diet from weaning to adulthood, generating respective dam/offspring dietary groups (C/C, HF/HF, HF+S/HF; n = 8/group). Body weight, blood pressure, and serum lipid profile were measured in female offspring at age 24 wk, and bone marrow endothelial progenitor cells (EPCs) were cultured. RESULTS: The results indicated that in the female offspring, the statin-fed (HF+S/HF) cohort had lower total and low-density lipoprotein cholesterol concentrations, were less obese and hypertensive, and had reduced C-reactive proteins (CRPs) compared with the HF/HF phenotype. The results also showed an increased bone marrow EPCs expressing colony numbers (P < 0.001) compared with the HF/HF phenotype. CONCLUSIONS: Results from the present study demonstrated that statin administration in early life to dams fed on a HFD had a significant effect on their female offspring in terms of reduction in cardiovascular risk factors. Additionally, statin administration to female offspring on an HFD during early life was associated with reduction in circulating CRPs and an increased bone marrow EPC numbers and colony-forming characteristics.

RESUMO

BACKGROUND: Several mapping algorithms have been published with the EORTC-QLQ-C30 for estimating EQ-5D-3L utilities. However, none are available with EQ-5D-5L. Moreover, a comparison between mapping algorithms in the same set of patients has not been performed for these two instruments simultaneously. In this prospective data set of 100 non-small cell lung cancer (NSCLC) patients, we investigate three mapping algorithms using the EQ-5D-3L and EQ-5D-5L and compare their performance. METHODS: A prospective non-interventional cohort of 100 NSCLC patients were followed up for 12 months. EQ-5D-3L, EQ-5D-5L and EORTC-QLQ-C30 were assessed monthly. EQ-5D-5L was completed at least 1 week after EQ-5D-3L. A random effects linear regression model, a beta-binomial (BB) and a Limited Variable Dependent Mixture (LVDM) model were used to determine a mapping algorithm between EQ-5D-3L, EQ-5D-5L and QLQ-C30. Simulation and cross validation and other statistical measures were used to compare the performances of the algorithms. RESULTS: Mapping from the EQ-5D-5L was better: lower AIC, RMSE, MAE and higher R(2) were reported with the EQ-5D-5L than with EQ-5D-3L regardless of the functional form of the algorithm. The BB model proved to be more useful for both instruments: for the EQ-5D-5L, AIC was -485, R(2) of 75 %, MAE of 0.075 and RMSE was 0.092. This was -385, 69 %, 0.099 and 0.113 for EQ-5D-3L respectively. The mean observed vs. predicted utilities were 0.572 vs. 0.577 and 0.515 vs. 0.523 for EQ-5D-5L and EQ-5D-3L respectively, for OLS; for BB, these were 0.572 vs. 0.575 and 0.515 vs. 0.518 respectively and for LVDMM 0.532 vs 0.515 and 0.569 vs 0.572 respectively. Less over-prediction at poorer health states was observed with EQ-5D-5L. CONCLUSIONS: The BB mapping algorithm is confirmed to offer a better fit for both EQ-5D-3L and EQ-5D-5L. The results confirm previous and more recent results on the use of BB type modelling approaches for mapping. It is recommended that in studies where EQ-5D utilities have not been collected, an EQ-5D-5L mapping algorithm is used.

RESUMO

BACKGROUND: There is strong evidence to suggest that social deprivation is linked to health inequalities. In the UK, concerns have been raised regarding disparities in the outcomes of acute cardiac services within the National Health Service (NHS). This study explored whether differences exist in (a) elective hospital presentation time (b) indicators of severity and disease burden and (c) treatment outcomes (hospital stay and mortality) on the basis of the index of multiple deprivation (IMD) status. DESIGN: This study was a retrospective analysis of data from NHS databases for 13,758 patients that had undergone cardiac revascularisation interventions at the Liverpool Heart and Chest Hospital between April 2007-March 2012. METHODS: The data was analysed by descriptive, univariate and multivariate statistics to explore the association between the IMD quintiles (Q1-Q5) and revascularisation type, elective presentation time, hospital length of stay and mortality. RESULTS AND CONCLUSIONS: Univariate analysis indicated that there were significant differences between patients from the most deprived areas (Q5) compared with patients from the least deprived areas (Q1), these included admission volumes, time before presentation to hospital and proportion of non-elective cases. After risk-adjustments, percutaneous coronary intervention patients from Q5 compared with Q1 had significantly greater length of hospital stay and risk of in-hospital major acute cardiovascular events. After multivariate adjustment for baseline risk factors, patients from Q5 were associated with significantly worse five-year survival as compared with Q1 (hazard ratio (HR) 1.52, 95% confidence interval (CI): 1.36-1.71; p < 0.001). In conclusion, there is evidence to suggest that inequalities in cardiac revascularisation choices and outcomes in the UK may be associated with social deprivation.

RESUMO

BACKGROUND: Diabetes has been shown to be associated with increased mortality and morbidity worldwide. This study explored whether diabetes significantly impacts on outcomes among elderly adults with cardiovascular disease (CVD) admitted to a specialist hospital in Southern Brazil. DESIGN: A prospective cohort study of 411 patients admitted to hospital after a cardiac event between 2008 and 2010. METHODS: The primary end point was death by all causes during the follow up period of 6 months from admission. All hospital death reports matched those reported by the Brazilian Public Health Death Records. Cumulative probability of survival by Kaplan-Meier plot and log rank tests compared hospital admissions with or without diabetes. Adjusted and unadjusted hazard ratios (HR) for overall mortality were calculated. RESULTS AND CONCLUSIONS: The mean ± SD age of the subjects was 69.8 years ± 14 and 50% were men. Overall study mortality was 8.7%. Half of the deaths occurred in patients &#8805;80 years (p=0.001). Diabetes was associated with 53% of the overall mortality (p<0.01) and 79% of the CVD-related deaths (p<0.03). The adjusted HR was 2.88 (95% CI 1.42-5.84) for diabetic patients aged &#8805;80 years. In conclusion, the results suggest that elderly patients of European origin with diabetes residing in Southern Brazil admitted to hospital for specialist CVD treatment have poorer survival and higher risk of further CVD events 6 months after hospital discharge compared with those without. We recommend that better strategies for managing CVD risk factors among elderly diabetic patients from similar patient cohorts in Brazil are necessary.

RESUMO

OBJECTIVES: The authors investigated whether zero-balance ultrafiltration (Z-BUF) during bypass significantly improves clinical and cost outcomes or biomarkers of kidney injury for patients with preoperative kidney impairment (estimated glomerular filtration rate [eGFR]<60 mL/minute) undergoing cardiac surgery. DESIGN: A single-center randomized controlled trial recruited, patients between 2010 and 2013, with a 12-months follow-up. SETTING: Hospital. PARTICIPANTS: One hundred ninety-nine patients undergoing cardiac surgery with cardiopulmonary bypass (CPB). INTERVENTIONS: Patients were assigned randomly to receive zero-balance ultrafiltration (Z-BUF) or not, with stratification for degree of kidney dysfunction and diabetes. MEASUREMENTS AND MAIN RESULTS: The authors assessed clinical efficacy and kidney function biomarkers. Cumulative probability of discharge from the intensive care unit (ICU) was assessed by Kaplan-Meier plots and was found not to be significantly different between the two trial arms (p = 0.61). After adjusting for EuroSCORE, diabetes, eGFR, cardioplegia types and type of surgery in a Cox proportional hazard model, hazard ratios (HR) for ICU length of stay between the Z-BUF and no-Z-BUF groups was not significantly different: HR (95% CI): 0.89 (0.66, 1.20; p = 0.44). In contrast, significant reductions in postoperative chest infections and the composite of clinical endpoints (death, strokes, and myocardial infarctions) in the Z-BUF group were observed. In addition, Z-BUF significantly abrogated the rise in the kidney damage markers urinary NGAL/creatinine ratio, urea, creatinine and eGFR during CPB and adverse events risks. CONCLUSIONS: Z-BUF during bypass surgery is associated with significant reductions in morbidity and biomarkers of CPB-induced acute kidney injury soon after CPB, which are indicative of clearance of inflammatory/immune mediators from the circulation.

RESUMO

Reports suggested that immediate post-aortic valve replacement (AVR); left ventricular (LV) dysfunction may be an important risk for morbidity and mortality in patients requiring positive inotropic support. Several factors have been identified as significant prognostic factors i.e., LV systolic dysfunction, LV diastolic dysfunction (LV-DD), heart failure and myocardial infarction (MI). Specific to pathophysiological changes associated with AS, markers of systolic LV function (e.g., LVEF) have been extensively studied in management, yet only a few studies have analysed the association between LV-DD and immediate post-operative LV dysfunction This review brings together the current body of evidence on this issue.

RESUMO

Previously we have demonstrated that maternal high fat diet (HF) during pregnancy increase cardiovascular risk in the offspring, and pharmacological intervention using statins in late pregnancy reduced these risk factors. However the effects of maternal HF-feeding and statin treatment during pregnancy on development of heart remain unknown. Hence we measured expression of genes involved in cell cycle progression (cyclin G1), ventricular remodelling brain natriuretic peptide (BNP), and environmental stress response small proline-rich protein 1A (SPRR 1A) in the offspring left ventricle (LV) from dams on HF with or without statin treatment. Female C57 mice were fed a HF diet (45% kcal fat) 4 weeks prior to conception, during pregnancy and lactation. From the second half of the pregnancy and throughout lactation, half of the pregnant females on HF diet were given a water-soluble statin (Pravastatin) in their drinking water (HF + S). At weaning offspring were fed HF diet to adulthood (generating dam/offspring dietary groups HF/HF and HF + S/HF). These groups were compared with offspring from dams fed standard chow (C 21% kcal fat) and fed C diet from weaning (C/C). LV mRNA levels for cyclin G1, BNP and SPRR 1A were measured by RT-PCR. Heart weights and BP in HF/HF offspring were higher versus C/C group. Maternal Pravastatin treatment reduced BP and heart weights in HF + S/HF female offspring to levels found in C/C group. LV cyclin G1 mRNA levels were lower in HF/HF versus both C/C and HF + S/HF offspring. BNP mRNA levels were elevated in HF/HF females but lower in males versus C/C. BNP gene expression in HF + S/HF offspring was similar to HF/HF. SPRR 1A mRNA levels were similar in all treatment groups. Statins given to HF-fed pregnant dams reduced cardiovascular risk in adult offspring, and this is accompanied by changes in expression of genes involved in adaptive remodelling in the offspring LV and that there is a gender difference.

RESUMO

There is growing interest in the use of the Internet for interacting with patients, both in terms of healthcare information provision and information gathering. In this article, we examine the issues in designing healthcare websites for elderly users. In particular, this article uses a year-long case study of the development of a web-based system for self-reporting of symptoms and quality of life with a view to examine the issues relating to website design for elderly users. The issues identified included the technical, social and medical aspects of website design for elderly users. The web-based system developed was based on the European Quality of Life 5-Dimensions health-status questionnaire, a commonly used tool for patient self-reporting of quality of life, and the more specific coronary revascularisation outcome questionnaire. Currently, self-reporting is generally administered in the form of paper-based questionnaires to be completed in the outpatient clinic or at home. There are a variety of issues relating to elderly users, which imply that websites for elderly patients may involve different design considerations to other types of websites.

RESUMO

The mechanism of release of proinflammatory cytokines by blood granulocytes in diabetes is unknown. We investigated whether diabetes mellitus affects the production of cytokines by granulocytes (PMN) and mononuclear cells (PBMCs) and whether this is modulated by NO. Isolated PMN and PBMC from with or without type-II diabetes mellitus were incubated at 37°C for 6 h with S-nitroso-N-acetylpenicillamine (SNAP) at 0, 1, and 100 µ M with or without lipopolysaccharides (LPS) stimulation (1 µ g/mL). Supernatants were assayed for tumor necrosis factor- α (TNF- α ) and interleukin-8 (IL-8) by sandwich ELISA. Significant increases in TNF- α and IL-8 were observed only in PMN from diabetic subjects with or without LPS stimulation and that exogenous NO inhibited further production of cytokines in a concentration-dependent manner. However, activity of PBMC when stimulated with LPS was greatly enhanced by diabetes, but not affected by NO production. Hence, suggesting that granulocytes activation and participation in diabetes related complications is modulated by NO bioavailability.

RESUMO

OBJECTIVES: To explore patients' views on the EuroQol-5D and Coronary Revascularisation Outcome Questionnaire, tools currently used for collecting patient-reported outcome measures in the English National Health Service. The key questions were as follows: (1) whether patients consider them sensitive enough to detect change in their health after cardiovascular disease interventions and (2) whether they consider the health-related quality-of-life questions as meaningful. METHODS: Data were collected on patients' views using focus groups. We held four focus groups selecting participants on the basis of their baseline and follow-up EuroQol-5D scores. Data were analysed using framework analysis and grounded theory. RESULTS: Focus group participants confirmed that they had derived substantial health benefits from their cardiac interventions despite the lack of measurable effects on the EuroQol-5D scores. Participants felt that the EuroQol-5D questionnaire was limited because of the following reasons: Their health fluctuates from day to day.They had difficulty assessing their general health status on the visual analogue scale.They felt that the Coronary Revascularisation Outcome Questionnaire was limited because of the following reasons: They did not understand the clinical terms used.The impact of tiredness on their quality of life was not captured.They were unable to distinguish between the effects of their heart condition and other health issues.Additionally, neither questionnaire considers the adjustments people have made to their domestic arrangements to improve their health-related quality of life. CONCLUSION: This study provides evidence that the two questionnaires do not capture some aspects of health that patients consider important. Furthermore, the presence of co-morbidities masks the symptoms relating to the heart disease and the effect of their cardiac interventions. Future work on patient-reported outcome measures should consider developing new questionnaires that address these major concerns.

RESUMO

BACKGROUND: We aimed to elucidate the association between gamma glutamyl transferase (GGT) activity with prevalence of premature coronary artery disease (CAD) in young Pakistani patients undergoing diagnostic coronary angiography. METHODS: A total of 218 young adults (age ≤ 45 years) underwent diagnostic angiography. Serum samples were taken from all the patients and analyzed for serum GGT activity, cholesterol and triglycerides. RESULTS: Coronary artery disease patients had significantly increased GGT activity (P = .001) and exhibited a significant positive correlation with blood pressure, cholesterol, blood glucose, and smoking and negative correlation with total antioxidant status (P < .01). CONCLUSION: The study revealed good diagnostic accuracy at cutoff of 35 U/L with a sensitivity of 92%, specificity of 81%, and diagnostic odds ratio of 48 in estimation of premature CAD in young Pakistanis.
