RESUMEN

AIMS AND OBJECTIVES: To explore person and family lifeworld narratives of chronic limb-threatening ischaemia (CLTI) after major amputation has been offered as a treatment option. BACKGROUND: Chronic limb-threatening ischaemia manifests as ischaemic pain, ulceration and/or gangrene and is receiving heightened attention due to the increasing health system burden from associated complex wounds and hospitalisations for repeat procedures. The patient and family impact of these manifestations is not well-reported: current studies largely seek to measure treatment outcomes. Patient-reported outcome measurements need to be developed but should be underpinned by rigorous qualitative research. DESIGN: Prospective, longitudinal, qualitative design using interpretive phenomenology. METHODS: The journeys of 19 people with CLTI were explored via 42 semi-structured interviews with 14 patient and 13 family participants. The initial interview was conducted soon after the advice of the need for major amputation, and where amputation followed, participants were invited for a second interview 6 months postprocedure. Hermeneutic phenomenological analysis was guided by Merleau-Ponty's philosophy of embodiment. RESULTS: People with embodied CTLI faced an existential crisis due to the catastrophic impact of creeping decay of their flesh and vascular system, relentless pain and a sense of spreading poison from gangrene, infection and drugs, which disrupted the interleaving of the physical and existential body. Consequent to the creeping decay and surgery, participants also experienced shifting body boundaries and an unreliable body. CONCLUSIONS: The lifeworld of the patient and family living with CTLI is irrevocably altered through the disruption of a spontaneous and reliable body. This shapes subsequent therapeutic relationships and discourse. RELEVANCE TO CLINICAL PRACTICE: People facing CLTI require early patient- and family-centred discussions about the possibility for major amputation and its potential to arrest the further decline of the body and to support the body's existential expression.

RESUMEN

OBJECTIVE/BACKGROUND: The aim was to summarise the evidence for the relationship between vein diameters and clinical severity, and elucidate the relationship between diameters and health related quality of life (HRQoL) METHODS: A systematic review was performed according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines. The MEDLINE and Embase databases were searched from 1946 to 31 August 2018. Reference lists of included studies were searched for further relevant papers. Full text studies in English reporting the relationship between great and small saphenous vein diameters and clinical severity and/or HRQoL scores measured using validated instruments were included. All study designs were included. Studies that did not include relationships between these parameters, non-English studies, and studies focusing on non-truncal veins were excluded. Two reviewers independently performed the study selection, data extraction, and risk of bias assessment. RESULTS: Eleven eligible studies were identified, reporting on 2,732 limbs (range 22-681). Four studies correlated truncal vein diameter with both clinical severity and HRQoL, while seven reported only on clinical severity measures. Multiple instruments were used to quantify HRQoL and clinical severity. Seven studies assessed the relationship with CEAP class, with the majority observing a positive correlation between vein diameter and disease severity. Four studies found weak correlations with VCSS, with one showing correlations with VCSS components. No significant relationship between diameters and HRQoL scores was reported. One study also revealed no correlation with Aberdeen Varicose Vein Questionnaire improvements post-treatment. The majority of studies failed to include C0 and C1 participants. CONCLUSIONS: While further studies are required to improve the level of evidence, the existing literature suggests that truncal vein diameters correlate with clinical severity. Diameters are a poor predictor of HRQoL, with no relationship to patients' perceived impact of chronic venous disease. As such, vein diameter should not be used as a measure to decide who needs venous intervention.

RESUMEN

Black patients have a higher prevalence of peripheral artery disease (PAD) than white patients, and also tend to have a greater extent and severity of disease, and poorer outcomes. The association of race with quality of health (QOH) after peripheral vascular intervention (PVI), however, is less well-known. In our study, we hypothesized that after PVI, black patients experience worse QOH than white patients. We retrospectively assessed racial differences in health status using responses to the Peripheral Arterial Questionnaire (PAQ) at baseline (pre-PVI) and up to 6 months following PVI among 387 patients. We used the PAQ summary score (which includes physical limitation, symptoms, social function and quality of life) as a measure of QOH. We compared QOH scores at baseline and at follow-up after PVI between black ( n=132, 34.1%) and white ( n=255, 65.9%) patients. We then computed the change in score from baseline to follow-up for each patient (the delta) and compared the median delta between the two groups. Multivariable regression was used to model the delta QOH after controlling for factors associated with race or with the delta QOH. There was no significant difference in mean QOH by race either at baseline ( p=0.09) or at follow-up ( p=0.45). There was no significant difference in the unadjusted median delta by race (white 25.3 vs black 21.5, p=0.28) and QOH scores improved significantly at follow-up in both groups, albeit the improvement was marginally lower in black compared with white patients after adjustment for baseline confounders ( b = -6.6, p=0.05, 95% CI -13.2, -0.11).

RESUMEN

AIMS AND OBJECTIVES: To examine the domains and the domain-specific characteristics within a peripheral arterial disease health-related quality of life framework for their usefulness in defining critical limb ischaemia health-related quality of life. BACKGROUND: Critical Limb Ischaemia presents a highly individualised set of personal and health circumstances. Treatment options include conservative management, revascularisation or amputation. However, the links between treatment decisions and quality of life require further investigation. DESIGN: The framework for this integrative review was the peripheral arterial disease-specific health-related quality of life domains identified by Treat-Jacobson et al. RESULTS: The literature expanded and refined Treat-Jacobson's framework by modifying the characteristics to better describe health-related quality of life in critical limb ischaemia. CONCLUSIONS: Given that critical limb ischaemia is a highly individualised situation with powerful health-related quality of life implications, further research focusing on patient and family-centred decision-making relating to therapeutic options and advanced care planning is required. RELEVANCE TO CLINICAL PRACTICE: A critical limb ischaemia-specific, health-related quality of life tool is required to capture both the unique characteristics of this disorder, and the outcomes for active or conservative care among this complex group of patients.

RESUMEN

In randomized treatment studies where the primary outcome requires long follow-up of patients and/or expensive or invasive obtainment procedures, the availability of a surrogate marker that could be used to estimate the treatment effect and could potentially be observed earlier than the primary outcome would allow researchers to make conclusions regarding the treatment effect with less required follow-up time and resources. The Prentice criterion for a valid surrogate marker requires that a test for treatment effect on the surrogate marker also be a valid test for treatment effect on the primary outcome of interest. Based on this criterion, methods have been developed to define and estimate the proportion of treatment effect on the primary outcome that is explained by the treatment effect on the surrogate marker. These methods aim to identify useful statistical surrogates that capture a large proportion of the treatment effect. However, current methods to estimate this proportion usually require restrictive model assumptions that may not hold in practice and thus may lead to biased estimates of this quantity. In this paper, we propose a nonparametric procedure to estimate the proportion of treatment effect on the primary outcome that is explained by the treatment effect on a potential surrogate marker and extend this procedure to a setting with multiple surrogate markers. We compare our approach with previously proposed model-based approaches and propose a variance estimation procedure based on a perturbation-resampling method. Simulation studies demonstrate that the procedure performs well in finite samples and outperforms model-based procedures when the specified models are not correct. We illustrate our proposed procedure using a data set from a randomized study investigating a group-mediated cognitive behavioral intervention for peripheral artery disease participants.

RESUMEN

OBJECTIVES: The VascuQol is a questionnaire for health related quality of life (HRQL) in patients with intermittent claudication (IC), and is frequently used to evaluate treatment effects. Yet, the interpretation of change in score on a questionnaire is not always obvious. The minimally important difference (MID) represents the smallest change in score on a questionnaire that is considered relevant by patients. This study aims to determine the MID for the VascuQol sumscore and its different domains for patients with IC. METHODS: A total of 118 participants were recruited from the SUPER study, a multicenter randomized controlled trial comparing angioplasty with supervised exercise therapy for alleviation of IC due to an iliac artery stenosis or occlusion. All patients completed the VascuQol and the Short Form 36 (SF-36) questionnaires at baseline and after 12 months of follow up. Two anchor based methods for MID calculation were applied. Two anchors were used: six global rating of change questions aimed at the VascuQol sumscore and subscales and the health transition item of the SF-36, both recorded at 12 months of follow up. RESULTS: The MID for the VascuQol sumscore ranged between 1.19 and 1.66 for improvement and 0.08 and 0.41 for deterioration. For the pain domain, MID values ranged from 1.48 to 1.91 for improvement and 0.19 to 0.34 for deterioration. Finally, for the activities domain MID values ranging from 1.55 to 2.2 and from 0.12 to 0.26 for improvement and deterioration were found, respectively. Since the correlations between the anchors and the symptom, social and emotional subscales were below the threshold of 0.3, the MID was not calculated for these subscales. CONCLUSIONS: The range of MID values found in this study is an indication of the smallest change score on the VascuQol questionnaire score that is considered relevant by patients with IC. They may help to better interpret trial results and set treatment goals.

RESUMEN

OBJECTIVE: This study describes the development and psychometric evaluation of a novel patient-reported single-item mobility measure. DESIGN: Prospective cohort study. SETTING: Four Veteran's Administration Medical Centers. SUBJECTS: Individuals undergoing their first major unilateral lower extremity amputation; 198 met inclusion criteria; of these, 113 (57%) enrolled. INTERVENTIONS: None. MAIN MEASURES: The Amputee Single Item Mobility Measure, a single item measure with scores ranging from 0 to 6, was developed by an expert panel, and concurrently administered with the Locomotor Capabilities Index-5 (LCI-5) and other outcome measures at six weeks, four months, and 12 months post-amputation. Criterion and construct validity, responsiveness, and floor/ceiling effects were evaluated. Responsiveness was assessed using the standardized response mean. RESULTS: The overall mean 12-month Amputee Single Item Mobility Measure score was 3.39 ±1.4. Scores for transmetatarsal, transtibial, and transfemoral amputees were 4.2 (±1.3), 3.2 (±1.5), and 2.9 (±1.1), respectively. Amputee Single Item Mobility Measure scores demonstrated "large" and statistically significant correlations with the LCI-5 scores at six weeks (r = 0.72), four months (r = 0.81), and 12 months (r = 0.86). At four months and 12 months, the correlation between Amputee Single Item Mobility Measure scores and hours of prosthetic use were r = 0.69 and r = 0.66, respectively, and between Amputee Single Item Mobility Measure scores and Trinity Amputation and Prosthesis Experience Scales functional restriction scores were r = 0.45 and r = 0.67, respectively. Amputee Single Item Mobility Measure scores increased significantly from six weeks to 12 months post-amputation. Minimal floor/ceiling effects were demonstrated. CONCLUSIONS: In the unilateral dysvascular amputee, the Amputee Single Item Mobility Measure has strong criterion and construct validity, excellent responsiveness, and does not exhibit floor/ceiling effects.

RESUMEN

OBJECTIVE: The aim of the study was to assess the relationship between depression and diabetic complications among urban south Indian type 2 diabetic subjects [T2DM]. METHODS: T2DM subjects [n = 847] were recruited from the Chennai Urban Rural Epidemiology Study [CURES], a population based study in Chennai (formerly Madras) in South India. A previously validated depression questionnaire [PHQ-12 item] was administered. Four field stereo retinal colour photography was done and diabetic retinopathy [DR] was classified according to the Early Treatment Diabetic Retinopathy Study grading system. Neuropathy was diagnosed if the vibratory perception threshold of the right great toe, measured by biothesiometry, was > or = 20. Nephropathy was diagnosed if urinary albumin excretion was > or = 300 microg/mg creatinine. Peripheral vascular disease [PVD] was diagnosed if an ankle-brachial index was < 0.9. Coronary artery disease [CAD] was diagnosed based on a past history of documented myocardial infarction and/or electrocardiographic evidence of Q wave and/or ST segment changes. RESULTS: Of the 847 T2DM studied, 198 (23.4%) were found have depression. The prevalence of depression was significantly higher among diabetic subjects with DR (35.0% vs 21.1%, p < 0.001), neuropathy (28.4% vs 15.9%, p = 0.023), nephropathy (35.6% vs 24.5%, p = 0.04) and PVD (48.0% vs 27.4%, p < 0.001) as compared to subjects without these complications. DR, neuropathy, nephropathy, and PVD were associated with depression even after adjusting for age, gender, duration of diabetes and glycated haemoglobin. DR (Odds ratio [OR] = 2.19, Confidence interval [CI]:1.45-3.51, p < 0.001) was associated with depression even after adjusting for neuropathy and nephropathy. There was also a significant association between depression and neuropathy, after adjusting for retinopathy and nephropathy (OR = 2.07, CI: 1.41-3.04, p < 0.001). There was a significant association of depression with nephropathy but this was lost (OR = 1.71, CI: 0.87-3.35, p = 0.119) after adjustment for retinopathy. PVD (OR = 3.52, CI: 1.94-6.40, p < 0.001) remained significantly associated with depression even after adjusting for CAD. However, there was no significant association of depression with CAD (OR = 0.73, CI: 0.42 -1.27, p = 0.264). CONCLUSION: Among Asian Indians, the prevalence of depression is higher in T2DM subjects with retinopathy, neuropathy, nephropathy and PVD compared to those without the respective complications.

RESUMEN

BACKGROUND: Few modifiable behaviors have been identified that are associated with slower rates of functional decline in persons with lower-extremity peripheral arterial disease. We determined whether higher levels of physical activity during daily life are associated with less functional decline in persons with peripheral arterial disease. METHODS AND RESULTS: The study population included 203 peripheral arterial disease participants who underwent vertical accelerometer-measured physical activity continuously over 7 days and were followed up annually for up to 4 years (mean, 33.6 months). Outcomes were average annual changes in 6-minute walk performance, usual-paced and fast-paced 4-m walking velocity, and the short performance physical battery. Analyses were adjusted for age, sex, race, comorbidities, body mass index, ankle brachial index, smoking, and walking exercise frequency. Higher baseline physical activity levels measured by a vertical accelerometer were associated with significantly less average annual decline in 6-minute walk performance (P for trend=0.010), fast-paced 4-m walking velocity (P for trend=0.002), and the short performance physical battery (P for trend=0.001). Compared with the lowest baseline quartile, those in the highest baseline quartile of physical activity had less annual decline in 6-minute walk performance (-50.82 versus -107.0 ft/y; P=0.019), fast-paced 4-m walking speed (-0.0034 versus -0.111 m . s(-1) . y(-1); P=0.002), and the short performance physical battery (-0.074 versus -0.829; P=0.005). CONCLUSIONS: Higher physical activity levels during daily life are associated with less functional decline among people with peripheral arterial disease. These findings may be particularly important for the large number of peripheral arterial disease persons without access to supervised walking exercise programs.

RESUMEN

OBJECTIVES: Gender disparities, particularly among young women with cardiovascular disease, are a growing cause for concern. Depression is a prevalent and prognostically important comorbidity in peripheral arterial disease (PAD), but its prevalence has not been described as a function of gender and age. Therefore, we compared depressive symptoms at the time of PAD diagnosis and 6 months later by gender and age in PAD patients. METHODS: The study enrolled 444 newly diagnosed patients with PAD (32% women) from two Dutch vascular outpatient clinics. Patients' depressive symptoms were assessed with the 10-item Center for Epidemiological Studies Depression Scale (CES-D) at baseline and 6 months later (CES-D scores >or=4 indicate significant depressive symptoms). Logistic regression models were constructed to evaluate the relationship among four gender-age groups (women <65 and >or=65 years; men <65 and >or=65 years [reference category]) and baseline and 6-month follow-up depressive symptoms. RESULTS: Initially, 33% of women <65 years had significant depressive symptoms, and 6 months later, significant depressive symptoms had developed in 19% of the other younger women. These rates were much higher than other gender-age groups (range at baseline, 11%-16%; 6-month incidence, 6%-10%; P or=65 years, whereas other gender-age groups were not at risk. Additional adjustment for change in the ankle-brachial index did not explain the increased depression risk in younger women (OR, 3.5; 95% CI, 1.2-10.2). CONCLUSIONS: Significant depressive symptoms are more common in younger women with PAD than in other gender-age groups, both at the time of diagnosis and 6 months later. To eradicate gender-based disparities in PAD, depression screening and monitoring in younger women may be an important direction for future research and intervention.

RESUMEN

OBJECTIVES: To investigate a hypothesised link between socio-economic deprivation and rates of major lower limb amputation within the catchment of a district general hospital in the United Kingdom. DESIGN: An analysis of a demographic database collated using patients identified by the OPCS codes for lower limb amputations. MATERIALS: All patients undergoing a lower limb amputation as a result of peripheral vascular disease, as identified by ICD-10 code, between January 2003 and January 2009 were included in the study. METHODS: A case-control study was undertaken, comparing the Index of Multiple Deprivation 2007 (IMD) scores of major lower limb amputees, to those of the catchment population. Multivariate analysis was not undertaken. RESULTS: A total of 327 patients underwent 445 lower limb amputations during the 6-year period. A comparative plot of cumulative frequency of IMD score in the catchment and amputation groups indicates greater numbers of major amputations in more deprived postcodes (P=0.004). The catchment population was further divided into population-matched deprivation quintiles. A significant increase in the number of amputations occurred in the two most deprived quintiles (OR (95%CI)=1.654 (1.121-2.440), P=0.011) CONCLUSIONS: This study indicates a positive association between increasing social deprivation and rates of lower limb amputation. If the most deprived quintiles are combined, this increase in amputation rates is approximately 65%. This inequity should be further investigated, and consideration given to targeted care within areas of greater social deprivation.

RESUMEN

OBJECTIVES: Smoking 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. DESIGN: Cohort study. METHODS: Data 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). RESULTS: After 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). CONCLUSIONS: There 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.

RESUMEN

Chronic venous disorders (CVD) and peripheral arterial disease (PAD) may affect diverse physical activity domains. How CVD and PAD and other relevant variables affect physical activity was examined in 569 opioid-addicted adults. Both CVD and PAD were significantly inversely related to daily walking, sports, and active living. Effects remained significant in the latent variable regression after controlling covariates. Overall activity was very low; most participants walked less than a half mile daily and rarely engaged in sports. Motivation for physical activity was the strongest predictor (ß = .55) of daily physical activity. Health-care professionals promoting physical activity for injection users should consider the vascular health of their legs and motivational variables in addition to general health.

RESUMEN

Segmental arterial mediolysis (SAM) is an uncommon condition and commonly missed diagnostic aetiology of acute abdominal pain, initially described in 1976. SAM is a non-inflammatory, non-atherosclerotic vasculopathy mostly involving the abdominal arteries with notable asymmetric involvement of the walls of the mesenteric arteries and their branches. Clinical presentation ranges from postprandial abdominal discomfort suggestive of mesenteric ischaemia to intra-abdominal bleeding. Pathophysiological explanation and prognosis of these cases are not well understood and therefore no clear guidelines for management exist. In this case report, we emphasise the imaging modalities used to reach the diagnosis and the management options available.

RESUMEN

BACKGROUND: This study assessed functional performance, calf muscle characteristics, peripheral nerve function, and quality of life in asymptomatic persons with peripheral arterial disease (PAD). METHODS AND RESULTS: PAD participants (n=465) had an ankle brachial index <0.90. Non-PAD participants (n=292) had an ankle brachial index of 0.90 to 1.30. PAD participants were categorized into leg symptom groups including intermittent claudication (n=215) and always asymptomatic (participants who never experienced exertional leg pain, even during the 6-minute walk; n=72). Calf muscle was measured with computed tomography. Analyses were adjusted for age, sex, race, ankle brachial index, comorbidities, and other confounders. Compared with participants with intermittent claudication, always asymptomatic PAD participants had smaller calf muscle area (4935 versus 5592 mm(2); P<0.001), higher calf muscle percent fat (16.10% versus 9.45%; P<0.001), poorer 6-minute walk performance (966 versus 1129 ft; P=0.0002), slower usual-paced walking speed (P=0.0019), slower fast-paced walking speed (P<0.001), and a poorer Short-Form 36 Physical Functioning score (P=0.016). Compared with an age-matched, sedentary, non-PAD cohort, always asymptomatic PAD participants had smaller calf muscle area (5061 versus 5895 mm(2); P=0.009), poorer 6-minute walk performance (1126 versus 1452 ft; P<0.001), and poorer Walking Impairment Questionnaire speed scores (40.87 versus 57.78; P=0.001). CONCLUSIONS: Persons with PAD who never experience exertional leg symptoms have poorer functional performance, poorer quality of life, and more adverse calf muscle characteristics compared with persons with intermittent claudication and a sedentary, asymptomatic, age-matched group of non-PAD persons.

RESUMEN

OBJECTIVE: To further document the experienced burden in patients with peripheral arterial disease (PAD), we compared the health status of patients with PAD and chronic heart failure (CHF). As a secondary aim, we studied clinical and socio-demographic correlates of health status in both conditions. METHODS: We conducted a cross-sectional observational study in four outpatient clinics in the Southern part of The Netherlands, with subjects consisting of ambulatory (346 PAD and 188 CHF) patients. All patients completed the Short-Form 12 to assess their physical and mental health status. Information about socio-demographic, clinical risk factors, and disease severity indices was obtained from patients' medical records. Propensity methodology was applied to enhance comparability between both medical conditions. RESULTS: Type of medical condition explained differences in health status (F = 33.1, P < .0001, Effect Size = 0.27). Impaired physical health status was more often reported in PAD patients (48.4%) compared with CHF patients (17.4%, Odds Ratio [OR] = 4.4, 95% Confidence Interval [CI] 2.3-8.8, P < .0001); impaired mental health status was more noted in CHF patients (43.5% vs. 22.0%, OR = 1.7, 95% CI 1.2-2.6, P = .002). In PAD, younger age (P = .002), low education (P = .02), cardiac history (P = .02), diabetes mellitus (P = .03), and a lower ankle brachial index (P = .003) were associated with worse physical health status; younger age (P = .01) and living without partner (P = .01) were associated with lower mental health status scores. In CHF, patients with comorbid diabetes mellitus (P < .001) and females (P = .001) reported worse physical health, whereas no clinical or socio-demographics were associated with mental health status. CONCLUSIONS: By contrasting PAD patients' health status with another chronic disabling condition, the impact of PAD on patients' physical health status became evident; whereas mental health status was more affected in CHF, patients with PAD reported a greater physical burden as compared with CHF patients. PAD patients who were younger, lower-educated, without a partner or had a cardiac history especially reported a higher disease burden. Clinicians need to be aware of these differences in order to develop tailor-made disease management programs for different groups of cardiovascular patients.

RESUMEN

BACKGROUND: Exploring patients' computer and internet use, their expectations and attitudes is mandatory for successful introduction of interactive online health-care applications in Angiology. PATIENTS AND METHODS: We included 165 outpatients suffering from peripheral arterial disease (PAD; n = 62) and chronic venous and / or lymphatic disease (CVLD; n = 103) in a cross-sectional-study. Patients answered a paper-based questionnaire. RESULTS: Patients were predominantly female (54.5%). 142 (86.1%) reported regular computer use for 9.7 +/- 5.8 years and 134 (81.2 %) used the internet for 6.2 +/- 3.6 years. CVLD-patients and internet-user were younger and higher educated, resulting in a significant difference in computer and internet use between the disease groups (p < 0.01 for both). Time spent online summed up to 4.3 +/- 2.2 days per week and 1.44 +/- 1.2 hours per day for all internet users without significant differences between the groups. The topics retrieved from the internet covered a wide spectrum and searches for health information were mentioned by 41.2 %. Although confidence in the internet (3.3 +/- 1.1 on a 1-6 Likert scale) and reliability in information retrieved from the internet (3.1 +/- 1.1) were relatively low, health-related issues were of high actual and future interest. 42.8% of the patients were even interested in interactive applications like health educational programs, 37.4% in self-reported assessments and outcome questionnaires and 26.9% in chatforums; 50% demanded access to their medical data on an Internetserver. Compared to older participants those < 50 yrs. used the internet more often for shopping, chatting, and e-mailing, but not for health information retrieval and interactive applications. CONCLUSIONS: Computers are commonly used and the internet has been adopted as an important source of information by patients suffering from PAD and CVLD. Besides, the internet offers great potentials and new opportunities for interactive disease (self-)management in angiology. To increase confidence and reliability in the medium a careful introduction and evaluation of these new online applications is mandatory.

RESUMEN

BACKGROUND: For patients with peripheral arterial disease (PAD), depression is associated with worse patency and recurrent symptoms in the treated leg, but its association with death or cardiovascular events in other vascular beds is unknown. OBJECTIVE: To assess the association between depression and mortality or cardiovascular events outside the affected leg after PAD revascularization. DESIGN: Retrospective cohort study. SUBJECTS: Two hundred fifty-seven consecutive patients undergoing lower extremity revascularization for symptomatic PAD at a single institution between January 2000 and May 2005 were included in this study. By protocol, patients were previously screened for depression and diagnosed by the primary care provider. MEASUREMENTS: The outcomes evaluated included a composite of death or major adverse cardiovascular events (MACE; coronary heart disease, contralateral PAD, or cerebrovascular event) as well as major outcome categories of death, coronary heart disease, contralateral PAD, or cerebrovascular events. RESULTS: At revascularization, 35.0% patients had been diagnosed with depression. Those with depression were significantly younger and more likely to use tobacco. By life-table analysis, patients with depression had significantly increased risk for death/MACE, coronary heart disease, and contralateral PAD events, but not cerebrovascular events or death. By multivariate analysis, patients with depression were at significantly increased risk for death/MACE (hazard ratio [HR] = 2.05; p < .0001), contralateral PAD (HR = 2.20; p = .009), and coronary heart disease events (HR = 2.31; p = .005) but not cerebrovascular events or death. CONCLUSIONS: Depression is common among patients undergoing revascularization for symptomatic PAD. After intervention, patients with depression are at significantly increased risk for coronary heart disease events and progression of contralateral PAD. Prospective analysis is required to confirm these results.
