Effect of Physical Activity after Recent Deep Venous Thrombosis: A Cohort Study

Effect of exercise after a deep venous thrombosis: A systematic review

Post-thrombotic syndrome (PTS) is a common complication after deep vein thrombosis (DVT) and has a major impact on physical symptoms, quality of life (QoL) and economic costs. Relatively simple lifestyle interventions as physical exercise might reduce PTS severity and increase QoL. To evaluate the direct and long-term effects of physical activity in patients with an acute or previous DVT. We conducted a systematic review through an additional search from 2007 up to March 2022, to complement the comprehensive systematic review of Kahn et al. Articles evaluating the effect of exercise after a DVT including symptoms, QoL and the incidence and severity of PTS, were included. Quality of the studies was assessed using a GRADE-like checklist and results were reported according to the PRISMA Statement. Ten studies were included, seven randomized controlled trials and three cohort studies. We identified three types of physical activity based on timing and duration; (1) early mobilisation in the acute phase of the DVT; (2) short duration exercise 1 year after DVT and (3) prolonged exercise during follow-up after a previous DVT. Early mobilisation showed improvement in QoL and pain reduction and after 2 years it resulted in a significant reduction of PTS severity. Prolonged supervised exercise resulted in improvement of QoL. In addition, positive effects on symptoms of venous insufficiency and muscle functions were observed. None of the included studies reported an increased risk of PTS or worsening of symptoms due to physical activity. Physical exercise after a DVT is safe, improves QoL, reduces pain and decreases PTS severity. Lifestyle intervention such as guided individualized training programs can be a useful supplementary therapy for patients after a DVT or for PTS patients. Optimal training programs may be identified by further studies that improve patient-oriented outcomes for both adults and children after a DVT.

Patient-Reported Outcomes in Venous Thromboembolism: A Systematic Review of the Literature, Current Challenges, and Ways Forward

BACKGROUND

Venous thromboembolism (VTE) affects >1.2 million Americans annually. Although the clinical outcomes and economic burdens of VTE have been well described, the impact of VTE on patients' health status has yet to be summarized. This systematic review summarizes how patient-reported outcome measures (PROMs) have been used in VTE to date.

METHODS AND RESULTS

PubMed/MEDLINE was queried for literature published through March 2023 using PROMs in a population of patients with VTE. Studies were excluded if the reference was an editorial, review, or case report, or if the study included patients with conditions other than VTE. Qualitative analyses were performed. After screening and exclusion, 136 references were identified; 5 described PROM development, 20 focused on PROM validation, and 111 used PROMs in outcomes research. The most used generic PROMs were the 36-item Short-Form Health Survey and EuroQol 5-dimensional questionnaire, and the most common disease-specific PROMs were the Venous Insufficiency Epidemiological and Economic Study-Quality of Life/Symptoms and the Pulmonary Embolism Quality of Life Questionnaire. PROMs were used to quantify the changes in health status after diagnosis, characterize the trajectory of subsequent improvement, and identify drivers of continued impairments in health status like postthrombotic syndrome and postpulmonary embolism syndrome. PROMs were also used to investigate the impact of novel treatment modalities on quality of life.

CONCLUSIONS

This review demonstrates the many benefits of PROM use, including quantifying changes in health status with treatment, capturing patients' experiences with the treatment itself, and identifying complications of VTE. Incorporating PROMs into VTE care will be an essential component of evaluating the effectiveness of novel therapies and should lead to improved shared decision-making for patients with VTE.

Exercise social support, barriers, and instructions in venous thromboembolism survivors: a descriptive study

Background

Diagnosis of venous thromboembolism (VTE) can be a significant life event that leads to changes in physical activity and exercise. Currently, little is known about the psychosocial experiences of survivors including perceived sources of social support, exercise barriers, and instructions for exercise from medical providers.

Objectives

This study aimed to explore psychosocial characteristics associated with VTE survivors' postdiagnosis exercise. Specifically, 1) what are the main sources of social support utilized by VTE survivors for exercise, 2) what are the most significant exercise barriers (eg, physical, social, and psychological) faced by VTE survivors, and 3) what specific information relative to exercise is provided by medical professionals following diagnosis?

Methods

VTE survivors (n = 472) were recruited through social media groups to participate in open-ended questions about psychosocial characteristics pertaining to postdiagnosis exercise.

Results

VTE survivors reported multiple forms of exercise social support, although almost 1 in 4 participants reported having no support for exercise. Several postdiagnosis exercise barriers were noted, and the data indicated a wide variety of information from their medical providers regarding engaging in exercise following their diagnosis, suggesting that the unique benefits and drawbacks to these instructions should be examined in more detail.

Conclusion

Although VTE survivors identified numerous categories of social support, there also exist numerous barriers, including a lack of standardized instructions for exercise. Further exploration of these characteristics is needed to better serve this population to encourage postdiagnosis exercise.

The effectiveness of exercise training in treating venous thromboembolism: a systematic review

This study aims to (1) evaluate the clinical safety of an exercise-based rehabilitation intervention for patients with venous thromboembolism (VTE); (2) separately summarize the effects of exercise training in deep vein thrombosis (DVT), pulmonary embolism (PE) and postthrombotic syndrome (PTS) survivors; and (3) identify commonly used exercise prescriptions and describe treatment progression. The Medline, Cochrane Library, and Embase databases were searched for randomized control trials and cohort studies published prior to February 2020 comparing exercise training interventions with non-exercise interventions for patients with VTE. Two reviewers independently reviewed and appraised the risk of bias of each study. Nine articles were included for review, five of which were randomized clinical trials, while three were prospective cohort studies, and one was a retrospective cohort trial. The results showed that exercise-based rehabilitation training was safe for patients diagnosed with VTE, including patients with DVT, PE, and PTS, but offered limited evidence to support the use of regular exercise as an intervention to improve exercise capacity in patients with VTE. Exercise-based rehabilitation in VTE survivors is clearly an emerging field with a lack of large, adequately powered randomized controlled trials. Existing evidence suggests that exercise is safe, but evidence to support exercise therapy as a replacement for standard care in all VTE patients is insufficient. Prescription and progression patterns should be tailored for individuals based on health conditions and functional deficits.

Reduced Physical Activity Levels in Children after a First Episode of Acute Venous Thromboembolism

OBJECTIVE

To assess physical activity in children following acute venous thromboembolism (VTE), examine predictors of reduced physical activity and its relationship to post-thrombotic syndrome.

STUDY DESIGN

Using a case-control study design, we enrolled 44 children with acute VTE, and compared physical activity using the Godin-Shephard Leisure-Time Physical Activity Questionnaire and health-related quality of life at 3 and 6 months after diagnosis relative to 44 age- and sex-matched controls. We assessed post-thrombotic syndrome scores using the Manco-Johnson Instrument to measure symptoms and signs attributed to sequelae of DVT in cases.

RESULTS

The physical activity of VTE cases was decreased at 3 months after diagnosis (36.6 ± 29.0 vs 56.8 ± 25.0; P = .002), but the differences disappeared at 6 months (57.5 ± 39.0 vs 56.8 ± 25.0; P = .60) relative to controls. At 3 and 6 months after diagnosis, overall, 70% and 50% of VTE cases were below their pre-VTE physical activity levels; providers did not address physical activity in the majority. In multivariable analysis, physical activity of cases was lower by 32 points for completely veno-occlusive thrombosis at diagnosis, 11 points for a diagnosis of pulmonary embolism relative to DVT, and increased by 0.72 points for every unit increase in health-related quality of life score. Physical activity at 3 months after diagnosis did not predict the short-term risk of post-thrombotic syndrome.

CONCLUSIONS

VTE limits physical activity in children in the first 3 months after the acute event, but the differences were nonexistent at 6 months. Only 50 percent of VTE survivors resume their pre-VTE physical activity levels within 6 months after diagnosis.

Effects of Sports Compression Socks on Performance, Physiological, and Hematological Alterations After Long-Haul Air Travel in Elite Female Volleyballers

Broatch, JR, Bishop, DJ, Zadow, EK, and Halson, S. Effects of sports compression socks on performance, physiological, and hematological alterations after long-haul air travel in elite female volleyballers. J Strength Cond Res 33(2): 492-501, 2019-The purpose of this investigation was to assess the merit of sports compression socks in minimizing travel-induced performance, physiological, and hematological alterations in elite female volleyball athletes. Twelve elite female volleyballers (age, 25 ± 2 years) traveled from Canberra (Australia) to Manila (Philippines), and were assigned to 1 of 2 conditions; compression socks (COMP, n = 6) worn during travel or a passive control (CON, n = 6). Dependent measures included countermovement jump (CMJ) performance, subjective ratings of well-being, cardiovascular function, calf girth, and markers of blood clotting, collected before (-24 hours, CMJ; -12 hours, all measures), during (+6.5 and +9 hours, subjective ratings and cardiovascular function), and after (+12 hours, all measures except CMJ; +24 hours and +48 hours, CMJ) travel. When compared with CON, small-to-large effects were observed for COMP to improve heart rate (+9 hours), oxygen saturation (+6.5 hours and +9 hours), alertness (+6.5 hours), fatigue (+6.5 hours), muscle soreness (+6.5 hours and +9 hours), and overall health (+6.5 hours) during travel. After travel, small-to-moderate effects were observed for COMP to improve systolic blood pressure (+12 hours), right calf girth (+12 hours), CMJ height (+24 hours), mean velocity (+24 hours), and relative power (+48 hours), compared with CON. COMP had no effect on the markers of blood clotting. This study suggests that compression socks are beneficial in combating the stressors imposed by long-haul travel in elite athletes, and may have merit for individuals frequenting long-haul travel or competing soon after flying.

Health-related quality of life after adverse bleeding events associated with antithrombotic drug therapy - A systematic review

Little is known about the health-related quality of life (HRQOL) following adverse bleeding events associated with antithrombotic drug therapy. This systematic review assesses the HRQOL of patients who suffered a bleeding event related to antithrombotic drug use. A literature search was performed using PubMed, EMBASE, and the Cochrane Library from inception through June 16, 2017. Studies measuring HRQOL after a bleeding event related to antithrombotic drug therapy for primary or secondary prevention of a thromboembolic event were included. Four studies with a total of 13,209 patients met the inclusion criteria, and of them, 3,649 patients developed a bleeding event. Patients who were included received antithrombotic drugs because of acute myocardial infarction or atrial fibrillation. EQ-5D, SF-36, and GHP MOS-13 were used to measure HRQOL. The follow-up time ranged from 6 to 29 months. Patients who suffered a bleeding event reported worse HRQOL compared to those who did not (EQ-5D - average increase on all domains of 0.09, p-values ranging from <0.001 to 0.003; SF-36 - average decrease on all domains of 21.4, p < 0.001; and GHP MOS-13 score - decrease of 11.9 points, p < 0.05) and an increased health concern (13.4-point increase; p < 0.05). In conclusion, adverse bleeding events occurring because of the use of antithrombotic agents are associated with a clinically relevant lower HRQOL and hence deserve more attention as part of the shared decision-making process between patients and providers. These data should be valuable for facilitating more substantive care and risk discussions regarding potential changes in outcome and rehabilitation.

What is the effect of venous thromboembolism and related complications on patient reported health-related quality of life? A meta-analysis

We conducted a meta-analysis of the literature to 1) assess the health-related quality of life for patients with a minimum follow-up of one year after an episode of pulmonary embolism (PE) or deep-vein thrombosis (DVT), and 2) to assess the HRQOL for patients who develop chronic thromboembolic pulmonary hypertension (CTEPH) and post thrombotic syndrome (PTS). PubMed, EMBASE, and the Cochrane Library were searched from inception to March 30, 2016. Data were pooled using random-effects meta-analysis, and heterogeneity was assessed with I² and Tau² tests. SF-12, SF-36, and VEINES-QOL were evaluated with pooled standardised mean difference (SMD) and 95 % confidence intervals (CI). Fourteen studies were included for meta-analysis. In patients who sustain a PE, physical health becomes impaired (p<0.001, 2 studies) but mental health appears to remain similar to population norms (p=0.069, 2 studies) after at least one year. Patients who develop CTEPH report worse physical (p<0.001, 1 study) and mental health (p=0.009, 1 study). In patients who suffer from a DVT, physical health (p=0.19, 9 studies), mental health (p=0.67, 9 studies), and disease specific quality of life (p=0.61, 8 studies) remain similar to population norms after at least one year. Patients who develop PTS, however, report worse physical health (p<0.001, 7 studies), mental health (p<0.001, 7 studies), and disease specific quality of life (p<0.001, 10 studies). These data can be used to educate patients during the shared decision making process that increasingly governs medical care today.

Post-thrombotic syndrome: a clinical review

Up to half of patients with proximal deep vein thrombosis (DVT) will develop post-thrombotic syndrome (PTS) despite optimal anticoagulant therapy. PTS significantly impacts upon quality of life and has major health-economic implications. This narrative review describes the pathophysiology, risk factors, and diagnosis, prevention and treatment of PTS, to improve our understanding of the disease and guide treatment. Relevant articles were identified through systematic searches of the PubMed, EMBASE and Cochrane databases between 1966 and November 2011. Studies were included for detailed assessment if they met the following criteria: published in English, human study participants, study population aged > 18 years, and lower limb post-thrombotic syndrome. All non-systematic reviews and single patient case reports were excluded. Recurrent thrombosis, thrombus location and obesity are major risk factors, whereas the importance of gender and age remain uncertain. The diagnosis of PTS is based on clinical findings in patients with a known history of DVT. Several clinical scales have been described, with the Villalta Score gaining increasing popularity. Adequate anticoagulation and use of elastic compression stockings (ECS) following DVT can reduce the incidence of PTS. Catheter-directed thrombolysis and mechanical thrombectomy of acute DVT may preserve valvular function. Studies to date of these techniques are encouraging, and have reported improved hemodynamics and a reduced incidence of PTS. The management of established PTS is challenging. Compression therapy, aimed at reducing the underling venous hypertension, remains the mainstay of treatment. This is despite a paucity of high-quality evidence to support its use. Pharmacologic and surgical treatments have also been described, with a number of studies citing symptomatic improvement.

Deep vein thromboses in users of opioid drugs: incidence, prevalence, and risk factors

BACKGROUND

Users of illicit opioids are at increased risk of hospital admission for deep vein thromboses (DVTs); however, the community prevalence, risk factors, and complications of DVTs in this group are poorly understood.

AIM

This study aimed to describe the prevalence of previous DVT for users of opioids in primary care; provide age- and sex-adjusted annual incidence rates of DVT; and explore factors associated with DVT, concordance with subsequent treatment, and complications.

DESIGN

A retrospective analysis of DVT prevalence and incidence, and analysis of risk factors for DVT using Poisson regression of incidence rates.

METHOD

A review of 734 patients in treatment for opioid addiction, who were registered to a single, specialised primary care practice in Middlesbrough, England.

RESULTS

The prevalence of previous DVT in users of opioids was 13.9% (95% confidence interval [CI] = 11.5 to 16.6) with an annual incidence rate of 3.2% (95% CI = 2.6 to 3.7). The incidence rate increased with age and for female users; an exploration of risk factors suggests that rising age, female sex, sex-worker status, and intravenous delivery all independently increase the risk of DVT. Concordance with treatment appeared reasonable and, compared with DVT in groups of people who do not use drugs, there was no evidence of increased risk of pulmonary embolism. Participants with previous DVT reported lower health and wellbeing scores.

CONCLUSION

Primary care providers should be aware of the considerably increased risk of DVT and its sequelae in users of intravenous drugs. Evidence for effective primary care prevention and the effective management of DVT complications is lacking; until this emerges, vigilance on the part of clinicians may help to minimise harm.

Effect of early physical activity on long-term outcome after venous thrombosis

OBJECTIVE

To determine if the level of self-reported physical activity 1 month after deep vein thrombosis (DVT) is associated with the risk of post-thrombotic syndrome (PTS) in the first 2 years post-DVT.

DESIGN

Prospective cohort study.

SETTING

Multicenter study (8 hospitals).

PARTICIPANTS

Patients presenting with objectively diagnosed acute DVT to 8 hospitals in Quebec and Ontario, Canada.

ASSESSMENT OF RISK FACTORS

We used validated questionnaires to measure physical activity (Godin questionnaire) and venous disease severity [generic physical quality of life (SF-36 PCS scale) or VEINES-QOL]. We adjusted for potential confounding effects of age, sex, and body mass index. We used multiple imputation to account for missing data.

MAIN OUTCOME MEASURES

Post-thrombotic syndrome (validated Villalta scale).

RESULTS

For the 387 patients enrolled, univariate analysis suggested no association between 1-month activity and risk of PTS. After adjusting for missing data and potential confounders, there was no evidence of a trend toward increasing risk of PTS with increasing physical activity [1.65 (95% confidence interval, 0.87-3.14) for mild-moderate activity and 1.35 (95% confidence interval, 0.69-2.67) for high activity]. The results were similar when PTS was dichotomized as none/mild versus moderate/severe. Finally, patients with PTS had lower levels of activity at 2 years post-DVT.

CONCLUSIONS

The level of self-reported exercise in the first month post-DVT is not associated with an increased risk of PTS in the first 2 years after DVT. Post-thrombotic syndrome is associated with decreased levels of physical activity 2 years after DVT.

What do we know of post-thrombotic syndrome? Current status of post-thrombotic syndrome in adults

The post-thrombotic syndrome (PTS) is a common but not completely understood and rarely studied sequela of an acute deep vein thrombosis. The influence of several risk factors on the incidence or severity of PTS is controversial. The therapeutic options for PTS are still limited. Appropriate medical compression stockings can reduce the incidence (-50 %) as well as the severity of PTS. In the case of severe, symptomatic PTS, they should be worn lifelong. As PTS is a chronic and often progressive disease, patients need regular clinical follow-up and encouragement to continuously wear their compression therapy. New strategies for treating PTS are needed.

Mobilização precoce na fase aguda da trombose venosa profunda de membros inferiores

O tratamento convencional da trombose venosa profunda na fase aguda consiste em restrição ao leito. Porém, estudos recentes contestam essa abordagem terapêutica, enfatizando que a mobilização precoce propicia resultados clínicos favoráveis. O objetivo deste estudo foi pesquisar em literatura científica, principalmente ensaios clínicos controlados, sobre a mobilização precoce de pacientes portadores de trombose venosa profunda de membros inferiores na fase aguda. Utilizou-se como estratégia de pesquisa o site PubMed para a busca de estudos relacionados à mobilização precoce, deambulação e trombose venosa profunda na fase aguda. Os artigos consultados abrangeram o período de 1992 a 2007. Em todos os estudos, a mobilização precoce esteve associada à heparina de baixo peso molecular e a terapia de compressão. Estudos avaliados nesta revisão têm demonstrado os benefícios na redução da dor e edema, com melhora da qualidade de vida, pela estratégia terapêutica de mobilização precoce em combinação com anticoagulação e compressão da perna na trombose venosa profunda, sem que ocorra maior risco de desfechos relevantes, como embolia pulmonar e morte.

Physical activity in patients with deep venous thrombosis: a systematic review

OBJECTIVES

We performed a systematic review to assess the benefits or risks of physical activity in patients with an acute or previous DVT of the leg.

DATA SOURCES

PubMed, EMBASE and Science Citation Index were searched without language restrictions up to July 2007. Bibliographies of retrieved articles and personal files were also searched.

REVIEW METHODS

Randomized trials and prospective cohort studies that included patients with acute or previous DVT, described an exercise intervention or exercise exposure, and described any related clinical outcome were selected. Data were independently extracted by 2 investigators.

RESULTS

Seven randomized trials and two prospective observational studies were included. Early exercise, compared with bed rest, was associated with a similar short-term risk of pulmonary embolism in patients with acute DVT and led to more rapid resolution of limb pain. In patients with acute DVT, a 6 month daily walking program led to similar degrees of vein recanalization and improvement in quality of life as controls. In patients with previous DVT, 30 min of vigorous treadmill exercise did not worsen venous symptoms and improved calf muscle flexibility; a 6 month exercise training program improved calf muscle strength and pump function; and high levels of physical activity at one month tended to be associated with reduced severity of postthrombotic symptoms during the subsequent 3 months.

CONCLUSIONS

Early walking exercise is safe in patients with acute DVT and may help to reduce acute symptoms. Exercise training does not increase leg symptoms acutely in patients with a previous DVT and may help to prevent or improve the postthrombotic syndrome.

Avaliação do nível de atividade física de estudantes de graduação das áreas saúde/biológica

FUNDAMENTAÇÃO: A prática regular de atividades físicas constitui importante fator na promoção da saúde e qualidade de vida da população. Para avaliar o nível de atividade física (NAF) de uma população, vários instrumentos são utilizados, entre eles o IPAQ (International Physical Activity Questionnaire). OBJETIVOS: Avaliar o NAF dos alunos de graduação em Educação Física em relação ao gênero e ao tempo de graduação, assim como comparar o NAF de estudantes de diferentes cursos das áreas saúde/biológica. MÉTODOS: Duzentos e oitenta indivíduos, sendo 194 estudantes de Educação Física (100 homens e 94 mulheres) e 86 estudantes (17 homens e 69 mulheres) de áreas saúde/biológica (Farmácia e Bioquímica, Odontologia e Ciências Biológicas). O instrumento utilizado para medida do nível de atividade física foi o Questionário Internacional de Atividade Física (IPAQ), em sua versão curta. RESULTADOS: No grupo de estudantes de Educação Física, encontrou-se incidência de 92% classificados como Muito Ativos ou Ativos; no entanto, não se observou diferença significativa (p > 0,05) entre os grupos masculino e feminino. Em relação aos outros cursos analisados, constatou-se que a amostra feminina é menos ativa fisicamente que a masculina (p < 0,05). Comparando os diferentes cursos analisados e considerando o valor conjunto das categorias Ativo/Muito Ativo, os estudantes de Biologia (86,9%) e Educação Física (90%) se mostraram mais ativos fisicamente que os da Farmácia (56%) e Odontologia (61,1%). No entanto, essa diferença não foi estatisticamente significativa (p > 0,05). CONCLUSÕES: Homens possuem maior nível de atividade física que as mulheres; os universitários avaliados não possuem padrões semelhantes nos diferentes cursos; e o nível de atividade física mantém-se constante durante o curso de Educação Física.
