Smoking Cessation has no Influence on Quality of Life in Patients with Peripheral Arterial Disease 5 Years Post-vascular Surgery

AbstractObjectivesSmoking is an important modifiable risk factor in patients with peripheral arterial disease (PAD). We investigated differences in quality of life (QoL) between patients who quitted smoking during follow-up and persistent smokers.DesignCohort study.MethodsData of 711 consecutively enrolled patients undergoing vascular surgery were collected in 11 hospitals in the Netherlands. Smoking status was obtained at baseline and at 3-year follow-up. A 5-year follow-up to measure QoL was performed with the EuroQol-5D (EQ-5D) and Peripheral Arterial Questionnaire (PAQ).ResultsAfter adjusting for clinical risk factors, patients, who quit smoking within 3 years after vascular surgery, did not report an impaired QoL (EQ-5D: odds ratio (OR) = 0.63, 95% confidence interval (CI) = 0.28–1.43; PAQ: OR = 0.76, 95% CI = 0.35–1.65; visual analogue scale (VAS): OR = 0.88, 95% CI = 0.42–1.84) compared with patients, who continued smoking. Current smokers were significantly more likely to have an impaired QoL (EQ-5D: OR = 1.86, 95% CI = 1.09–3.17; PAQ: OR = 1.63, 95% CI = 1.00–2.65), although no differences in VAS scores were found (OR = 1.17, 95% CI = 0.72–1.90).ConclusionsThere was no effect of smoking cessation on QoL in PAD patients undergoing vascular surgery. Nevertheless, given the link between smoking, complications and mortality in this patient group, smoking cessation should be a primary target in secondary prevention

Differences between patients with a preserved and a depressed left ventricular function: a report from the EuroHeart Failure Survey

Aims Due to a lack of clinical trials, scientific evidence regarding the management of patients with chronic heart failure and preserved left ventricular function (PLVF) is scarce. The EuroHeart Failure Survey provided information on the characteristics, treatment and outcomes of patients with PLVF as compared to patients with a left ventricular systolic dysfunction (LVSD). Methods and results We performed a secondary analysis using data from the EuroHeart Failure Survey, only including patients with a measurement of LV function \batchmode \documentclass[fleqn,10pt,legalpaper]{article} \usepackage{amssymb} \usepackage{amsfonts} \usepackage{amsmath} \pagestyle{empty} \begin{document} $(n=6806)$ \end{document}. We selected two groups: patients with LVSD (54%) and patients with a PLVF (46%). Patients with a PLVF were, on average, 4 years older and more often women (55% vs. 29%, respectively, p <0.001) as compared to LVSD patients, and were more likely to have hypertension (59% vs. 50%, \batchmode \documentclass[fleqn,10pt,legalpaper]{article} \usepackage{amssymb} \usepackage{amsfonts} \usepackage{amsmath} \pagestyle{empty} \begin{document} $p{<}0.001$ \end{document}) and atrial fibrillation (25% vs. 23%, \batchmode \documentclass[fleqn,10pt,legalpaper]{article} \usepackage{amssymb} \usepackage{amsfonts} \usepackage{amsmath} \pagestyle{empty} \begin{document} $p=0.01$ \end{document}). PLVF patients received less cardiovascular medication compared to PLVF patients, with the exception of calcium antagonists. Multivariate analysis revealed that LVSD was an independent predictor for mortality, while no differences in treatment effect on mortality between the two groups was observed. A sensitivity analysis, using different thresholds to separate patients with and without LVSD revealed comparable findings. Conclusions In the EuroHeart Failure Survey, a high percentage of heart failure patients had PLVF. Although major clinical differences were seen between the groups, morbidity and mortality was high in both group

Further validation of the peripheral artery questionnaire:Results from a peripheral vascular surgery survey in the Netherlands

AbstractObjectivesPeripheral arterial disease (PAD) is associated with adverse cardiovascular events and can significantly impair patients' health status. Recently, marked methodological improvements in the measurement of PAD patients' health status have been made. The Peripheral Artery Questionnaire (PAQ) was specifically developed for this purpose. We validated a Dutch version of the PAQ in a large sample of PAD patients.DesignCross-sectional study.MethodsThe Dutch PAQ was completed by 465 PAD patients (70% men, mean age 65±10 years) participating in the Euro Heart Survey Programme. Principal components analysis and reliability analyses were performed. Convergent validity was documented by comparing the PAQ with EQ-5D scales.ResultsThree factors were discerned; Physical Function, Perceived Disability, and Treatment Satisfaction (factor loadings between 0.50 and 0.90). Cronbach's α values were excellent (mean α=0.94). Shared variance of the PAQ domains with EQ-5D scales ranged from 3 to 50%.ConclusionsThe Dutch PAQ proved to have good measurement qualities; assessment of Physical Function, Perceived Disability, and Treatment Satisfaction facilitates the monitoring of patients' perceived health in clinical research and practice. Measuring disease-specific health status in a reliable way becomes essential in times were a wide array of treatment options are available for PAD patients

Barriers and facilitators for shared decision making in older patients with multiple chronic conditions: A systematic review

Background The aim of this study was to describe barriers and facilitators for shared decision making (SDM) as experienced by older patients with multiple chronic conditions (MCCs), informal caregivers and health professionals. Methods A structured literature search was conducted with 5 databases. Two reviewers independently assessed studies for eligibility and performed a quality assessment. The results from the included studies were summarized using a predefined taxonomy. Results Our search yielded 3838 articles. Twenty-eight studies, listing 149 perceived barriers and 67 perceived facilitators for SDM, were included. Due to poor health and cognitive and/or physical impairments, older patients with MCCs participate less in SDM. Poor interpersonal skills of health professionals are perceived as hampering SDM, as do organizational barriers, such as pressure for time and high turnover of patients. However, among older patients with MCCs, SDM could be facilitated when patients share information about personal values, priorities and preferences, as well as information about quality of life and functional status. Informal caregivers may facilitate SDM by assisting patients with decision support, although informal caregivers can also complicate the SDM process, for example, when they have different views on treatment or the patient’s capability to be involved. Coordination of care when multiple health professionals are involved is perceived as important. Conclusions Although poor health is perceived as a barrier to participate in SDM, the personal experience of living with MCCs is considered valuable input in SDM. An explicit invitation to participate in SDM is important to older adults. Health professionals need a supporting organizational context and good communication skills to devise an individualized approach for patient care

Management and outcome of patients with established coronary artery disease: the Euro Heart Survey on coronary revascularization

Aims The purpose of the Euro Heart Survey Programme of the European Society of Cardiology is to evaluate to which extent clinical practice endorses existing guidelines as well as to identify differences in population profiles, patient management, and outcome across Europe. The current survey focuses on the invasive diagnosis and treatment of patients with established coronary artery disease (CAD). Methods and results Between November 2001 and March 2002, 7769 consecutive patients undergoing invasive evaluation at 130 hospitals (31 countries) were screened for the presence of one or more coronary stenosis >50% in diameter. Patient demographics and comorbidity, clinical presentation, invasive parameters, treatment options, and procedural techniques were prospectively entered in an electronic database (550 variables+29 per diseased coronary segment). Major adverse cardiac events (MACE) were evaluated at 30 days and 1 year. Out of 5619 patients with angiographically proven coronary stenosis (72% of screened population), 53% presented with stable angina while ST elevation myocardial infarction (STEMI) was the indication for coronary angiography in 16% and non-ST segment elevation myocardial infarction or unstable angina in 30%. Only medical therapy was continued in 21%, whereas mechanical revascularization was performed in the remainder [percutaneous coronary intervention (PCI) in 58% and coronary artery bypass grafting (CABG) in 21%]. Patients referred for PCI were younger, were more active, had a lower risk profile, and had less comorbid conditions. CABG was performed mostly in patients with left main lesions (21%), two- (25%), or three-vessel disease (67%) with 4.1 diseased segments, on average. Single-vessel PCI was performed in 82% of patients with either single- (45%), two- (33%), or three-vessel disease (21%). Stents were used in 75% of attempted lesions, with a large variation between sites. Direct PCI for STEMI was performed in 410 cases, representing 7% of the entire workload in the participating catheterization laboratories. Time delay was within 90 min in 76% of direct PCI cases. In keeping with the recommendations of practice guidelines, the survey identified under-use of adjunctive medication (GP IIb/IIIa receptor blockers, statins, and angiotensin-converting enzyme-inhibitors). Mortality rates at 30 days and 1 year were low in all subgroups. MACE primarily consisted of repeat PCI (12%). Conclusion The current Euro Heart Survey on coronary revascularization was performed in the era of bare metal stenting and provides a global European picture of the invasive approach to patients with CAD. These data will serve as a benchmark for the future evaluation of the impact of drug-eluting stents on the practice of interventional cardiology and bypass surger

Continuously improving the practice of cardiology

Guidelines for the management of patients with cardiovascular disease are designed to assist cardiologists and other physicans in their practice. Surveys are conducted to assess whether guidelines are followed in practice. The results of surveys on acute coronary syndromes, coronary revascularisation, secondary prevention, valvular heart disease and heart failure are presented. Comparing surveys conducted between 1995 and 2002, a gradual improvement in use ofsecondary preventive therapy is observed. Nevertheless, important deviations from established guidelines are noted, with a significant variation among different hospitals in the Netherlands and in other European countries. Measures for fiuther improvement of clinical practice indude more rapid treatment of patients with evolving myocardial infarction, more frequent use of clopidogrel and glycoprotein IIb/IIIa receptor blockers in patients with acute coronary syndromes, more frequent use of 5-blockers in patients with heart failure and more intense measures to encourage patients to stop smoking. Targets for the proportion ofpatients who might receive specific therapies are presented

Clinical validity of a disease-specific health status questionnaire: The peripheral artery questionnaire

BackgroundMeasuring patient-centered outcomes is becoming increasingly important in patients with peripheral arterial disease (PAD), both as a means of determining the benefits of treatment and as an aid for disease management. In order to monitor health status in a reliable and sensitive way, the disease-specific measure Peripheral Artery Questionnaire (PAQ) was developed. However, to date, its correlation with traditional clinical indices is unknown. The primary aim of this study was to better establish the clinical validity of the PAQ by examining its association with functional indices related to PAD. Furthermore, we hypothesized that the clinical validity of this disease-specific measure is better as compared with the EuroQol-5-dimensional (EQ-5D), a standardized generic instrument.MethodsData on 711 consecutive PAD patients undergoing surgery were collected from 11 Dutch hospitals in 2004. At 3-year follow-up, questionnaires including the PAQ, EQ-5D, and EuroQol-Visual Analogue Scale (EQ VAS) were completed in 84% of survivors. The PAQ was analyzed according to three domains, as established by a factor analyses in the Dutch population, and the summary score. Baseline clinical indices included the presence and severity of claudication intermittent (CI) and the Lee Cardiac Risk Index.ResultsAll three PAQ domains (Physical Function, Perceived Disability, and Treatment Satisfaction) were significantly associated with CI symptoms (P values < .001-.008). Patients with claudication had significant lower PAQ summary scores as compared with asymptomatic patients (58.6 ± 27.8 vs 68.6 ± 27.8, P = < .001). Furthermore, the PAQ summary score and the subscale scores for Physical Functioning and Perceived Disability demonstrated a clear dose-response relation for walking distance and the Lee Risk Index (P values < .001-.031). With respect to the generic EQ-5D, the summary EQ-5D index was associated with CI (0.81 ± 0.20 vs 0.76 ± 0.24, P = .031) but not with walking distance (P = .128) nor the Lee Risk Index (P = .154). The EQ VAS discriminated between the clinical indices (P values = .003-.008), although a clear dose-response relation was lacking.ConclusionThe clinical validity of the PAQ proved to be good as the PAQ subscales discriminated well between patients with or without symptomatic PAD and its severity as defined by walking distance. Furthermore, the PAQ subscales were directly proportional to the presence and number of risk factors relevant for PAD. For studying outcomes in PAD patients, the disease-specific PAQ is likely to be a more sensitive measure of treatment benefit as compared with the generic EQ VAS, although the latter may still be of value when comparing health status across different diseases. Regarding disease management, we advocate the use of the disease-specific PAQ as its greater sensitivity and validity will assist its translation into clinical practice
