Profile and Correlates of Health-related Quality of Life in Chinese Patients with Coronary Heart Disease.

Background:Although coronary heart disease (CHD) is one of the major cardiovascular diseases, risk factors associated with the health-related quality of life (HRQoL) of CHD patients remain unclear. The present study was designed to determine the profile and significant factors of the HRQoL in CHD patients.Methods:A cross-sectional study was conducted in rural communities of Fangshan District, Beijing, China. Socio-demographic, lifestyle, and comorbidity information of CHD patients were collected by a structured questionnaire and medical records. HRQoL was measured using European Quality of Life 5-dimensions (EQ-5D) scale and EQ Visual Analog Scale (EQ-VAS). Multiple linear and logistic regressions were performed to explore the association of potential risk factors with HRQoL scores and each EQ-5D, respectively.Results:Totally, 1928 CHD patients (mean age 61.64 ± 9.24 years; female:male = 2.4:1) were enrolled in the study. The mean score of EQ-5D index and EQ-VAS were 0.889 ± 0.172 and 71.56 ± 17.65, respectively. Multiple linear regression revealed that marital status, physical activity, moderate alcohol drinking, and family's population were positive independent correlates of EQ-VAS, whereas diabetes mellitus and stroke were negative independent correlates (all P < 0.05). Age and stroke were negatively while physical activity, moderate alcohol drinking, family's population and household income were positively correlated with EQ-5D index (all P < 0.05) independently. In addition, each of the five HRQoL dimensions had various specific determinants, including obesity, underweight, smoking or education.Conclusions:Findings of the study highlight certain socio-demographic, lifestyle factors, and comorbid stroke or diabetes mellitus as correlates of HRQoL in Chinese CHD patients. Large-scale cohort studies should be carried out to confirm our results in the future.

Comparison of quality-of-life measures after radial versus femoral artery access for cardiac catheterization in women: Results of the Study of Access Site for Enhancement of Percutaneous Coronary Intervention for Women quality-of-life substudy

In the SAFE-PCI for Women trial, patient preference for radial access for future procedures was greater than for femoral access. We sought to assess whether radial or femoral access impacts formal measures of quality-of-life (QOL) among women undergoing cardiac catheterization. We assessed QOL using European quality of life-5 dimensions (EQ-5D) and EQ visual analog scale (EQ-VAS) scores among 304 women randomized to radial or femoral arteriotomy in the SAFE-PCI for Women trial at sites with QOL substudy approval. Patient surveys were administered at baseline, hospital discharge, and 30 days (for percutaneous coronary intervention patients). Women randomized to both treatments had similar EQ-5D index and EQ-VAS scores at baseline, hospital discharge, and 30-day follow-up. After adjustment for baseline scores, there was no effect of assigned treatment on EQ-5D (discharge 0.004; 95% CI -0.03 to 0.04; 30 days -0.03; 95% CI -0.09 to 0.02) or EQ-VAS (discharge -1.31; 95% CI -4.74 to 2.12; 30 days -2.10; 95% CI -8.92 to 4.71) scores. At discharge, 60.5% versus 63.5% (P = .60) of patients in radial and femoral groups were free from access site pain; at 30 days, rates were 85.7% versus 77.6% (P = .30), respectively. Patient preference for the same access strategy for repeat procedures was greater in the radial versus femoral group (77.2% vs 26.8%; P < .0001). Using established QOL instruments, we did not measure any difference in QOL or functional status according to access site strategy in women undergoing cardiac catheterization, yet patient preference for the radial approach was significantly greater. Other factors influencing patient choice for radial access should be investigated.

High aortic pulse wave velocity is associated with poor quality of life in surgical aortic valve stenosis patients.

Aortic stiffness is an emerging risk factor for cardiovascular disease. The predictive value of aortic pulse wave velocity (PWV) for quality of life (QoL) and severity of surgical aortic valve stenosis (AS) have not been examined. PWV was measured in patients undergoing aortic valve replacement (AVR) for AS. QoL [SF-36 and European QoL 5-dimensions (EQ-5D) questionnaires] was assessed pre- and postoperatively (409 ± 159 days). PWV was analysed: (i) as a continuous variable and (ii) as a dichotomous variable (PWV-norm and PWV-high groups) according to the published normal reference value. Fifty-six patients (16 females), mean age of 71 ± 8.4 years, were included, and 50 (89%) patients completed follow-up. The two groups were matched for age, gender and classical haemodynamic measurements. There was no significant relation between AS severity and PWV. PWV-norm patients (n = 35) scored significantly better than PWV-high (n = 21) patients in the EQ-5D visual analogue scale and the EQ-5D index pre- (P < 0.001 and P = 0.03, respectively) and postoperatively (P < 0.001 for both). In SF-36, PWV-norm group scored better than PWV-high group in physical health domains preoperatively and in all domains postoperatively. Spearman's correlation was significant between PWV and QoL component summaries pre- and postoperatively. Among PWV, age and gender, multiple regression analysis demonstrated PWV to be independently related to QoL pre- and postoperatively (P-values ranged from <0.01 to <0.05). PWV does not correlate with AS severity, but is associated with QoL before and after AVR. The published European PWV reference values can be used to categorise preoperative AS patients for QoL risk stratification.

Health Burden Associated with Visual Impairment in Singapore: The Singapore Epidemiology of Eye Disease Study

To assess the impact of visual impairment (VI) on health-related quality of life and to compare the health burden of VI and other health conditions in Singapore. Population-based cross-sectional study. We studied the 10 009 adults (3353 Chinese, 3397 Indians, and 3259 Malays) who underwent a comprehensive eye assessment and completed the European Quality of Life-5 Dimensions (EQ-5D) questionnaire in the Singapore Epidemiology of Eye Disease Study. We estimated the effects of VI, obesity, hypertension, diabetes, and hyperlipidemia on the EQ-5D index score using linear regression models and the association between VI and self-reported EQ-5D health problems using logistic regression models. We compared prevalence-based quality-adjusted life-year (QALY) loss associated with VI and other health conditions. For each condition, QALY loss was calculated for 100 000 persons in 1 year using associated reduction in EQ-5D index score estimated in regression analysis as disutility. The EQ-5D index score and annual QALY loss. The EQ-5D index score decreased with increasing VI severity in all 3 ethnicities. For example, after adjusting for sociodemographic characteristics, the difference in EQ-5D index score between adults with bilateral severe VI and those without VI was -0.044 (95% confidence interval [CI], -0.089 to 0.001) in Chinese, -0.127 (95% CI, -0.237 to -0.017) in Indians, and -0.085 (95% CI, -0.148 to -0.022) in Malays. In all 3 ethnicities, VI was associated with reporting of problems in mobility (e.g., odds ratio [OR], 3.69 for Chinese with bilateral severe VI; 95% CI, 1.21-12.13) and usual activities (e.g., OR, 6.51 for Chinese with bilateral severe VI; 95% CI, 1.59-26.58). In Indians, VI was also associated with anxiety or depression (e.g., OR, 2.68 for bilateral severe VI; 95% CI, 1.11-6.50). The annual QALY loss associated with VI was 511.8 in Chinese, 608.8 in Indians, and 706.7 in Malays, greater than that associated with other health conditions examined in this study. Visual impairment is associated with substantial health burden among Asians in Singapore. The relatively high burden of VI highlights the importance of VI prevention. The ethnic difference exhibited in this burden warrants further study.

Intravesical Hyaluronic Acid and Chondroitin Sulphate Improve Symptoms and Quality of Life in Patients with Late Radiation Tissue Cystitis: An Investigative Pilot Study

Intravesical hyaluronic acid (HA) and chondroitin sulphate (CS) instillation are effective for urinary tract infections (UTIs) and bladder pain syndrome. This study aimed to evaluate the tolerability, safety and efficacy of intravesical HA and CS instillation in patients with late radiation tissue cystitis (LRTC). In this pilot study, tolerability was reported as discontinuation or deviation of the protocol, safety as general or local side effects, efficacy as improvement of bladder capacity and frequency, quality of life (QoL) through the European Quality of Life 5-Dimensions (EQ-5D) (details at http://www.controlled-trials.com/ISRCTN37534393 ). Thirty-two patients with LRTC were enrolled. Twenty-seven patients (84.8%) received a mean of 12.2±0.3 months of instillation therapy. Only two patients (6.2%) developed a urinary tract infection from instillation, which required antibiotic treatment, nevertheless not compromising the therapy schedule. No male patient developed a urethral stricture. Intravesical instillation was associated with a significant increase (&gt;50%) of bladder capacity from baseline (66.9ml) both at 3 months (101.9ml; p&lt;0.001) and 12 months (174.4 ml; p&lt;0.001). EQ-5D index significantly increased from baseline to both 3 and 12 months (0.26, 0.69 and 0.96, respectively; p&lt;0.001). Intravesical co-administration of HA and CS improved bladder function, symptoms and QoL in patients with LRTC.

Assessment of quality of life among Taiwanese patients with visual impairment

This study aims at evaluating the relationship between visual impairment and health-related quality of life (QoL) by identifying factors that affect the EQ-5D index score and Visual Functioning Questionnaire (VFQ) global score, and determining whether the VFQ-25 scores and the European Quality of Life-5 Dimensions (EQ-5D) scores are correlated. This cross-sectional study comprised 318 patients aged 40 years or more presenting with best corrected visual acuity (BCVA) of 20/40 or worse in the better eye.Patients received comprehensive ophthalmologic examinations, and were administered the National Eye Institute VFQ-25 and the EQ-5D instruments. A higher VFQ-25 score indicates a better QoL and, after conversion of the EQ-5D scores to an index score, a higher EQ-5D index score indicates a better QoL. On multivariate analysis of the EQ-5D index scores, women and those with arthritis were found to have significantly worse QoL, and the EQ-5D index score was increased by every unit increase in BCVA or mean deviation. Multivariate analysis of the VFQ-25 scores revealed that a history of heart disease, arthritis, and eye diseases, such as age-related macular degeneration or diabetic retinopathy, had significant negative effects on patients' QoL, and VFQ-25 global score was decreased by every unit increase in logMAR. According to this analysis, patients' QoL was improved by each unit increase in BCVA or mean deviation. The correlation between the two questionnaires was only weak to moderate. Visual impairment was associated with lower QoL, as assessed by either questionnaire in Taiwanese patients.
