Periprocedural management and clinical outcomes of invasive procedures after venous thromboembolism: from the COMMAND VTE registry.

Anticoagulation therapy is prescribed for the prevention of recurrence in patients with venous thromboembolism, which could be temporarily interrupted during invasive procedures. The COMMAND VTE Registry is a multicenter registry enrolling 3027 consecutive patients with acute symptomatic VTE in Japan between January 2010 and August 2014. We identified patients who underwent invasive procedures during the entire follow-up period and evaluated periprocedural managements and clinical outcomes at 30 days after invasive procedures. During a median follow-up period of 1213 (IQR: 847-1764) days, 518 patients underwent invasive procedures with the cumulative incidences of 5.8% at 3 months, 11.1% at 1 year, and 24.0% at 5 years. Among 382 patients in high bleeding-risk category of invasive procedures, anticoagulation therapy had been discontinued already in 62 patients (16%) and interrupted temporarily in 288 patients (75%) during the invasive procedures with bridging anticoagulation therapy with heparin in 214 patients (56%). Among 80 patients in low bleeding-risk category, anticoagulation therapy had been already discontinued in 15 patients (19%) and interrupted temporarily in 31 patients (39%) during invasive procedure with bridging anticoagulation therapy with heparin in 17 patients (21%). At 30 days after the invasive procedures, 14 patients (2.7%) experienced recurrent VTE, while 28 patients (5.4%) had major bleeding. This study elucidated the real-world features of peri-procedural management and prognosis in patients with VTE who underwent invasive procedures during follow-up in the large multicenter VTE registry. The 30-day incidence rates of recurrent VTE and major bleeding events were 2.7% and 5.4%.

Clinical characteristics and outcomes of patients with venous thromboembolism according to diagnosis on weekends versus on weekdays.

There are uncertainties on the influence of the days of diagnosis in a week (weekends versus weekdays) on clinical outcomes in patients with acute venous thromboembolism (VTE), including pulmonary embolism (PE) and deep vein thrombosis (DVT). The COMMAND VTE registry is a multicenter cohort study enrolling 3027 consecutive patients with acute symptomatic VTE. The current study population consisted of 337 patients diagnosed on weekends and 2690 patients diagnosed on weekdays. We compared the clinical characteristics, management strategies and 30-day outcomes between the 2 groups. The patients diagnosed on weekends more often presented with PE (72% vs. 55%, P < 0.001), and with more severe hemodynamic condition for PE patients. The patients diagnosed on weekends more often received initial parenteral anticoagulation therapy and thrombolysis than those diagnosed on weekdays. The cumulative 30-day incidence of all-cause death was not significantly different between the two groups among PE patients (diagnosis on weekends: 6.2% vs. diagnosis on weekdays: 6.5%, P = 0.87), as well as among DVT patients (0.0% vs. 1.5%, P = 0.24). The most frequent cause of deaths was fatal PE in both groups among PE patients. The risks for recurrent VTE and major bleeding at 30-day were not significantly different between the 2 groups among PE patients, nor among DVT only patients. In conclusion, the VTE patients diagnosed on weekends presented more often with PE, and with more severe condition for PE patients. Nevertheless, the risk for 30-day mortality was not significantly different between patients diagnosed on weekends and on weekdays.

Risk Factors for Major Bleeding During Anticoagulation Therapy in Cancer-Associated Venous Thromboembolism　- From the COMMAND VTE Registry.

BACKGROUND: Patients with cancer-associated venous thromboembolism (VTE) are at high risk for recurrent VTE and are recommended to receive prolonged anticoagulation therapy if they are at a low risk for bleeding. However, there are no established risk factors for bleeding during anticoagulation therapy.Methods and Results:The COMMAND VTE Registry is a multicenter retrospective registry enrolling 3,027 consecutive patients with acute symptomatic VTE among 29 Japanese centers. The present study population consisted of 592 cancer-associated VTE patients with anticoagulation therapy. We constructed a multivariable Cox proportional hazard model to estimate the hazard ratio (HR) and 95% confidence interval (CI) of the potential risk factors for major bleeding. During a median follow-up period of 199 days, major bleeding occurred in 72 patients. The cumulative incidence of major bleeding was 5.8% at 3 months, 13.8% at 1 year, 17.5% at 2 years, and 28.1% at 5 years. The most frequent major bleeding site was gastrointestinal tract (47%). Terminal cancer (adjusted HR, 4.17; 95% CI, 2.22-7.85, P<0.001), chronic kidney disease (adjusted HR, 1.89; 95% CI 1.06-3.37, P=0.031), and gastrointestinal cancer (adjusted HR, 1.78; 95% CI, 1.04-3.04, P=0.037) were independently associated with an increased risk of major bleeding. CONCLUSIONS: Major bleeding events were common during anticoagulation therapy in real-world cancer-associated VTE patients. Terminal cancer, chronic kidney disease, and gastrointestinal cancer were the independent risk factors for major bleeding.

Age- and Body Size-Adjusted Left Ventricular End-Diastolic Dimension in a Japanese Hospital-Based Population.

BACKGROUND: Using the normal values for the East Asian population, we evaluated age- and body size-adjusted left ventricular end-diastolic dimension (LVEDD) and its prognostic impact in a hospital-based population in Japan. Methods and Results: We retrospectively analyzed data obtained from 4,444 consecutive patients who had undergone both transthoracic echocardiography and electrocardiography at Kitano Hospital in 2013. Those who presented with a history of previous episodes of myocardial infarction and severe or moderate valvular disease or with low ejection fraction (<50%) were excluded from the analysis. We calculated LVEDD adjusted by age and body surface area. A total of 3,474 patients were categorized into 3 groups: 401 with large adjusted LVEDD, 2,829 with normal adjusted LVEDD, and 244 with small adjusted LVEDD. Mean patient age in the large, normal, and small adjusted LVEDD groups was 66.6±18.4, 65.6±15.7, and 62.1±15.5 years, respectively (P<0.001). After adjusting for confounding factors, the excess adjusted 3-year risk of primary outcome of large adjusted LVEDD relative to normal LVEDD was significant (HR, 1.40; 95% CI: 1.08-1.78). The risk for primary outcomes of small adjusted LVEDD relative to normal adjusted LVEDD was significantly lower (HR, 0.55; 95% CI: 0.34-0.85). CONCLUSIONS: Adjusted large LVEDD has a deleterious impact on long-term mortality, whereas small LVEDD carried a significantly lower risk.

Clinical Characteristics and Outcomes of Venous Thromboembolisms According to an Out-of-Hospital vs. In-Hospital Onset　- From the COMMAND VTE Registry.

BACKGROUND: Differences in the clinical characteristics and outcomes of venous thromboembolisms (VTEs) based on different clinical situations surrounding the onset might be important for directing appropriate treatment strategies, but have not yet been appropriately evaluated. Methods and Results: The COMMAND VTE Registry is a multicenter registry enrolling 3,027 consecutive patients with acute symptomatic VTEs in Japan between January 2010 and August 2014. We divided the study population into 3 groups: Out-of-hospital onset (n=2,308), In-hospital onset with recent surgery (n=310), and In-hospital onset without recent surgery (n=374). Active cancer was most prevalent in the In-hospital onset without recent surgery group, and least in the Out-of-hospital onset group (Out-of-hospital onset group: 20%, In-hospital onset with recent surgery group: 26%, and In-hospital onset without recent surgery group: 38%, P<0.001). The cumulative 5-year incidence of recurrent VTEs did not significantly differ across the 3 groups (11.4%, 5.8%, and 8.7%, respectively; P=0.11). The cumulative 5-year incidences of major bleeding and all-cause death were highest in the In-hospital onset without recent surgery group (11.1%, 8.5%, and 23.3%, P<0.001; 26.8%, 24.9%, and 48.4%, P<0.001, respectively). CONCLUSIONS: In the real-world VTE registry, the clinical characteristics and long-term outcomes substantially differed according to the clinical situation of VTE onset, suggesting the need for different treatment strategies for VTEs in different clinical settings.

Sex Differences in Clinical Characteristics and Outcomes of Patients With Venous Thromboembolism　- From the COMMAND VTE Registry.

BACKGROUND: It remains controversial whether sex category is a risk for recurrent venous thromboembolism (VTE) and major bleeding among VTE patients.Methods and Results:The COMMAND VTE Registry is a multicenter registry enrolling 3,027 consecutive acute symptomatic VTE patients from 29 centers in Japan between January 2010 and August 2014. We compared the clinical characteristics and outcomes of men and women. Men accounted for 1,169 (39%) and women 1,858 (61%). Compared with women, men were younger (64.9±14.7 vs. 68.6±15.6 years old, P<0.001), more often had prior VTE (7.2% vs. 5.1%, P=0.02), and less often had transient risk factors for VTE (30% vs. 40%, P<0.001). The proportions of active cancer and pulmonary embolism were comparable between men and women (24% vs. 22%, P=0.26; 56% vs. 57%, P=0.48, respectively). The cumulative 3-year incidences of recurrent VTE, major bleeding, and all-cause death were not significantly different between men and women (7.0% vs. 8.6%, P=0.47; 10.6% vs. 9.2%, P=0.25; 25.2% vs. 23.4%, P=0.35, respectively). The adjusted risks of men relative to women for recurrent VTE and for major bleeding remained insignificant (HR 0.83, 95% CI 0.63-1.09, P=0.17; HR 1.15, 95% CI 0.90-1.47, P=0.25, respectively). CONCLUSIONS: In real-world VTE patients, the clinical characteristics differed between men and women, but there was not a large sex-related difference in the risks for recurrent VTE or major bleeding.

Cancer-Associated Venous Thromboembolism in the Real World　- From the COMMAND VTE Registry.

BACKGROUND: There is a paucity of data on the management and prognosis of cancer-associated venous thromboembolism (VTE), leading to uncertainty about optimal management strategies.Methods and Results:The COMMAND VTE Registry is a multicenter registry enrolling 3,027 consecutive acute symptomatic VTE patients in Japan between 2010 and 2014. We divided the entire cohort into 3 groups: active cancer (n=695, 23%), history of cancer (n=243, 8%), and no history of cancer (n=2089, 69%). The rate of anticoagulation discontinuation was higher in patients with active cancer (43.5%, 27.0%, and 27.0%, respectively, at 1 year, P<0.001). The cumulative 5-year incidences of recurrent VTE, major bleeding, and all-cause death were higher in patients with active cancer (recurrent VTE: 17.7%, 10.2%, and 8.6%, P<0.001; major bleeding: 26.6%, 8.8%, and 9.3%, P<0.001; all-cause death: 73.1%, 28.6%, 14.6%, P<0.001). Among the 4 groups classified according to active cancer status, the cumulative 1-year incidence of recurrent VTE was higher in the metastasis group (terminal stage group: 6.4%, metastasis group: 22.1%, under chemotherapy group: 10.8%, and other group: 5.8%, P<0.001). CONCLUSIONS: In a current real-world VTE registry, patients with active cancer had higher risk for VTE recurrence, bleeding, and death, with variations according to cancer status, than patients without active cancer. Anticoagulation therapy was frequently discontinued prematurely in patients with active cancer in discordance with current guideline recommendations.

Thrombolysis with tissue plasminogen activator in patients with acute pulmonary embolisms in the real world: from the COMMAND VTE registry.

There is still uncertainty about the optimal usage of thrombolysis for acute pulmonary embolisms (PEs), leading to a widely varying usage in the real world. The COMMAND VTE Registry is a multicenter retrospective registry enrolling consecutive patients with acute symptomatic venous thromboembolisms (VTEs) in Japan. The present study population consisted of 1549 patients with PEs treated with tissue plasminogen activator (t-PA) thrombolysis (N = 180, 12%) or without thrombolysis (N = 1369). Thrombolysis with t-PA was implemented in 33% of patients with severe PEs, and 9.2% of patients with mild PEs with a wide variation across the participating centers. Patients with t-PA thrombolysis were younger, and less frequently had active cancer, history of major bleeding, and anemia. At 30 days, t-PA thrombolysis as compared to no thrombolysis was associated with similar mortality rates (5.0% vs. 6.9%, P = 0.33), but a lower adjusted mortality risk (OR 0.41; 95% CI 0.18-0.90, P = 0.03), while it was associated with a trend for higher rates of major bleeding (5.6% vs. 2.9%, P = 0.06) and a significantly higher adjusted risk for major bleeding (OR 2.39; 95% CI 1.06-5.36, P = 0.03). In patients with severe PEs, the mortality rates at 30 days were significantly lower in the t-PA thrombolysis group than no thrombolysis group (15% vs. 37%, P = 0.006). In the present real-world VTE registry in Japan, t-PA thrombolysis was not infrequently implemented, not only in patients with severe PEs, but also in patients with mild PEs. A substantial mortality risk reduction might be suggested with t-PA thrombolysis in patients with severe PEs.

Influence of baseline anemia on long-term clinical outcomes in patients with venous thromboembolism: from the COMMAND VTE registry.

The influence of anemia on the long-term clinical outcomes has not been fully evaluated in patients with venous thromboembolism (VTE). We evaluated the influence of anemia among 3012 patients in the COMMAND VTE Registry with a median follow-up period of 1219 days. The outcomes measures were ISTH major bleeding, recurrent VTE and all-cause death. There were 1012 patients (34%) with moderate/severe anemia (Hb ≤ 10.9 g/dl), 615 patients (20%) with mild anemia (Hb 11.0-12.9 g/dl for men, and 11.0-11.9 g/dl for women), and 1385 patients (46%) without anemia. The cumulative 5-year incidence of major bleeding was significantly higher in patients with anemia (moderate/severe anemia: 17.6%, mild anemia: 12.1%, and no anemia: 8.7%, P < 0.001). After adjusting the confounders, the excess risk of mild and moderate/severe anemia, respectively, relative to no anemia for major bleeding remained significant (mild: adjusted HR 1.41: [95% CI 1.00-1.98], P = 0.048; moderate/severe: adjusted HR 1.91: [95% CI 1.42-2.58], P < 0.001, respectively). The excess risk of moderate/severe anemia relative to no anemia was also significant for mortality (adjusted HR 2.89: 95% CI 2.45-3.42, P < 0.001), but the risk was neutral for recurrent VTE (adjusted HR 1.05: 95% CI 0.76-1.45, P = 0.77). In conclusions, VTE patients with mild and moderate/severe anemia had higher risk for major bleeding events without significant excess risk for recurrent VTE events, and the risk for major bleeding events increased according to the severity of anemia. We should pay more attention to the optimal intensity and duration of anticoagulation in VTE patients with anemia.

Risk factors for post-thrombotic syndrome in patients with deep vein thrombosis: from the COMMAND VTE registry.

Post-thrombotic syndrome (PTS) is the most common chronic complication of deep vein thrombosis (DVT). Identifying high-risk patients for the development of PTS might be useful for its prevention. The COMMAND VTE Registry is a multicenter registry that enrolled 3027 consecutive patients with acute symptomatic venous thromboembolisms (VTEs) in Japan between January 2010 and August 2014. The current study population consisted of 1298 patients with lower extremities DVTs who completed 3-year follow-up for those who developed PTS and those without PTS. We investigated risk factors for the development of PTS at the time of DVT diagnosis, using a multivariable logistic regression analysis. Of the entire 1298 study patients, 169 (13%) patients were diagnosed with PTS within 3 years. The rate for anticoagulation discontinuation during follow-up was not significantly different between those with and without PTS. Chronic kidney disease (OR 2.21, 95% CI 1.45-3.39, P < 0.001), leg swelling (OR 4.15, 95% CI 2.25-7.66, P < 0.001), absence of transient risk factors for VTEs (OR 2.39, 95% CI 1.55-3.67, P < 0.001), active cancer (OR 3.66, 95% CI 2.30-5.84, P < 0.001), and thrombophilia (OR 2.07, 95% CI 1.06-4.04, P = 0.03) were independent risk factors for the development of PTS. In this real-world Japanese DVT registry, we could identify several important risk factors for the development of PTS at the time of DVT diagnosis.

Anticoagulation Therapy for Venous Thromboembolism in the Real World　- From the COMMAND VTE Registry.

BACKGROUND: Venous thromboembolism (VTE) has a long-term risk of recurrence, which can be prevented by anticoagulation therapy.Methods and Results:The COMMAND VTE Registry is a multicenter registry enrolling 3,027 consecutive patients with acute symptomatic VTE between January 2010 and August 2014. The entire cohort was divided into the transient risk (n=855, 28%), unprovoked (n=1,477, 49%), and cancer groups (n=695, 23%). The rate of anticoagulation discontinuation was highest in the cancer group (transient risk: 37.3% vs. unprovoked: 21.4% vs. cancer: 43.5% at 1 year, P<0.001). The cumulative 5-year incidences of recurrent VTE, major bleeding and all-cause death were highest in the cancer group (recurrent VTE: 7.9% vs. 9.3% vs. 17.7%, P<0.001; major bleeding: 9.0% vs. 9.4% vs. 26.6%, P<0.001; and all-cause death: 17.4% vs. 15.3% vs. 73.1%, P<0.001). After discontinuation of anticoagulation therapy, the cumulative 3-year incidence of recurrent VTE was lowest in the transient risk group (transient risk: 6.1% vs. unprovoked: 15.3% vs. cancer: 13.2%, P=0.001). The cumulative 3-year incidence of recurrent VTE beyond 1 year was lower in patients on anticoagulation than in patients off anticoagulation at 1 year in the unprovoked group (on: 3.7% vs. off: 12.2%, P<0.001), but not in the transient risk and cancer groups (respectively, 1.6% vs. 2.5%, P=0.30; 5.6% vs. 8.6%, P=0.44). CONCLUSIONS: The duration of anticoagulation therapy varied widely in discordance with current guideline recommendations. Optimal duration of anticoagulation therapy should be defined according to the risk of recurrent VTE and bleeding as well as death.

Optimal quality of vitamin K antagonist therapy in Japanese patients with venous thromboembolism.

BACKGROUND: Vitamin K antagonist (VKA) remains an essential option for venous thromboembolism (VTE), although direct oral anticoagulants have become available. However, there is a paucity of data on the optimal intensity and quality of control for VKA in Japanese. METHODS: The COMMAND VTE Registry is a multicenter registry enrolling consecutive 3027 patients with acute symptomatic VTE among 29 centers in Japan. The current study population consisted of 1938 patients who received VKA with prothrombin time-international normalized ratio (PT-INR) measurement >5 times. The primary outcome measure was a composite of symptomatic VTE recurrence or major bleeding at 1 year. The presumed optimal quality of VKA therapy was defined as the combination of PT-INR range and time in therapeutic range (TTR) with the numerically lowest event rate. RESULTS: The group with TTR ≥70 % based on PT-INR range ≥1.5 and <2.0 showed the lowest cumulative incidence rate. The cumulative 1-year incidence and the adjusted risk for the primary outcome measure were significantly lower in the optimal quality group than in the non-optimal quality group (5.2 % vs. 11.7 %, p = 0.001, and HR 0.49, 95%CI 0.28-0.81). Similarly, the cumulative 1-year incidences of a recurrent VTE, major bleeding, and all-cause death were significantly lower in the optimal quality group (recurrent VTE: 2.5 % vs. 6.0 %, p = 0.02; major bleeding: 2.8 % vs. 7.0 %, p = 0.008; and all-cause death: 2.8 % vs. 12.6 %, p < 0.0001). The lower risk of the optimal quality group relative to non-optimal quality group for the clinical outcomes was consistent regardless of the etiology of VTE (active cancer, transient risk factor, and unprovoked). CONCLUSIONS: The current VTE registry showed the optimal intensity of VKA therapy was target PT-INR range ≥1.5 and <2.0, which could support the current Japanese guideline recommendation, and the good quality of control for VKA therapy of TTR ≥70 % was independently associated with better outcomes.

Impact of no, distal, and proximal deep vein thrombosis on clinical outcomes in patients with acute pulmonary embolism: From the COMMAND VTE registry.

BACKGROUND: The majority of acute pulmonary embolism (PE) is caused by thrombus developed from leg veins. However, impact of concomitant deep venous thrombosis (DVT) on clinical outcomes has not been fully evaluated in patients with acute PE. METHODS: The COMMAND VTE Registry is a multicenter registry enrolling consecutive 3027 patients with acute symptomatic venous thromboembolism (VTE) in Japan. The current study population consisted of 655 acute PE patients who underwent lower extremities ultrasound examination at diagnosis for the assessment of concomitant DVT status. RESULTS: There were 424 patients with proximal DVT (64.7%), 162 patients with distal DVT (24.7%), and 69 patients with no DVT (10.5%). The cumulative 90-day incidence of all-cause death was higher in proximal DVT patients than in distal DVT and no DVT patients (7.9%, 2.5%, and 1.4%, p = 0.01). Regarding the causes of death, the cumulative 90-day incidence of PE-related death was low, and not significantly different across the 3 groups (1.4%, 0.6%, and 1.7%, p = 0.62). The most frequent cause of death was cancer in proximal and distal DVT patients. There were no significant differences in 90-day rates of recurrent VTE and major bleeding, regardless of the status of concomitant DVT (2.9%, 3.2%, and 2.2%, p = 0.79, and 1.5%, 4.4%, and 4.9%, p = 0.46, respectively). CONCLUSIONS: Acute PE with proximal DVT at diagnosis was associated with a higher risk for short-term mortality than in patients without DVT, while the risk for short-term mortality was not significantly different between distal DVT patients and patients without DVT.

Severity of pulmonary embolism at initial diagnosis and long-term clinical outcomes: From the COMMAND VTE Registry.

BACKGROUND: There is a paucity of data on the long-term clinical outcomes according to the severity of pulmonary embolism (PE) at initial diagnosis. METHODS: The COMMAND VTE Registry is a multicenter registry enrolling 3027 consecutive patients with acute symptomatic venous thromboembolism (VTE). After excluding 1312 patients without PE, the current study population consisted of 1715 patients with PE, who were divided into 3 groups according to the clinical severity; massive PE, sub-massive PE and low-risk PE. RESULTS: There were 179 patients (10%) with massive PE, 742 patients (43%) with sub-massive PE, and 794 patients (46%) with low-risk PE. By the landmark analysis at 3 months, the cumulative incidences of recurrent VTE were similar among the 3 groups both within and beyond 3 months (Massive PE: 2.9%, Sub-massive PE: 4.2%, and Low-risk PE: 3.3%, P = 0.61, and 4.3%, 8.8%, and 7.8% at 5 years, P = 0.47, respectively). After adjusting confounders, the risk of massive PE relative to low-risk PE for recurrent VTE beyond 3 months remained insignificant (adjusted HR 0.54, 95% CI: 0.13-1.51, P = 0.27). Patients with massive PE at initial diagnosis more often presented as severe recurrent PE events than those with sub-massive and low-risk PE. CONCLUSIONS: In the current real-world large registry, the long-term risk of overall recurrent VTE in patients with massive PE at initial diagnosis did not significantly differ from those with sub-massive and low-risk PE beyond 3 months, although patients with massive PE at initial diagnosis more frequently developed recurrent VTE as PE with severe clinical presentation.

Impact of aortic plaque morphology on survival rate and incidence of a subsequent embolic event ­ long-term follow-up data ­.

BACKGROUND: There are no reports about the long-term follow-up data of patients with aortic plaques among the Japanese population. The purpose of this study was to clarify the frequency of patients with severe aortic plaques and the impact of aortic plaque morphology on the prognosis. METHODS AND RESULTS: We retrospectively investigated 1,570 consecutive patients who underwent transesophageal echocardiography. Survival rate and subsequent embolic event rate were compared between patients with severe aortic plaque (>5 mm in thickness) and control patients. The relationship between aortic plaque morphology and prognosis was also estimated according to the presence of ulceration, calcification, hypoechoic plaques, and mobile plaques. The mean follow-up period was 8.7 years. Among 1,570 patients, severe aortic plaque was detected in 92 patients (5.9%). These 92 patients showed a significantly low survival rate and high subsequent embolic event rate compared to control patients (5-year survival rate: 69% vs 94%; 5-year embolic event free rate: 52% vs 95%). Among patients with severe aortic plaque, only ulceration was associated with a low survival rate (hazards ratio: 2.4, 95% confidence interval (CI): 1.1-5.2) and only mobile plaque was associated with a high embolic event rate (hazards ratio: 2.2; 95%CI: 1.1-5.1). CONCLUSIONS: Aortic plaque >5 mm in thickness was a predictor of poor prognosis. In the presence of aortic plaque >5 mm, ulceration was a predictor of a low survival rate and mobile plaque was a predictor of a high embolic event rate.

Validation of simplified PESI score for identification of low-risk patients with pulmonary embolism: From the COMMAND VTE Registry.

BACKGROUND: The simplified pulmonary embolism severity index (sPESI) score has been reported to be useful in predicting 30-day mortality for patients with pulmonary embolism, which helps the identification of low-risk patients for early hospital discharge or home treatment. However, therapeutic decision-making should also be based on the risks of adverse events other than mortality. METHODS: The COMMAND VTE Registry is a multicentre registry enrolling consecutive patients with acute symptomatic venous thromboembolism in Japan between January 2010 and August 2014, and the current study population consisted of 1715 patients with pulmonary embolism. We calculated the sPESI score for each patient, and compared 30-day rates of mortality, recurrent venous thromboembolism and major bleeding between sPESI scores of 0 and 1 or greater. RESULTS: Patients with a sPESI score of 0 accounted for 383 (22%) patients, and 110 (6.4%) patients died within 30 days. The cumulative 30-day incidence of mortality was lower in patients with a sPESI score of 0 than those with a sPESI score of 1 or greater (0.5% vs. 8.1%, log rank P<0.001). There was no significant difference in the cumulative 30-day incidence of recurrent venous thromboembolism between patients with a sPESI score of 0 and 1 or greater (1.3% vs. 2.8%, log rank P=0.11). The cumulative 30-day incidence of major bleeding was lower in patients with a sPESI score of 0 than those with a sPESI score of 1 or greater (1.1% vs. 4.0%, log rank P=0.005). CONCLUSIONS: In patients with a sPESI score of 0, the 30-day mortality, recurrent venous thromboembolism and major bleeding rates were reasonably low. The sPESI score could be useful to identify candidates for early hospital discharge or home treatment.

Predictive ability of modified Ottawa score for recurrence in patients with cancer-associated venous thromboembolism: From the COMMAND VTE Registry.

INTRODUCTION: The external validation of the modified Ottawa score to predict the risk of recurrence in patients with cancer-associated venous thromboembolism (VTE) has not yet been firmly established. The present study aimed to evaluate the utility and limitations of the modified Ottawa score in the risk stratification of recurrent VTE in patients with cancer-associated VTE. MATERIALS AND METHODS: The COMMAND VTE Registry is a multicenter retrospective registry enrolling 3027 consecutive patients with acute symptomatic VTE among 29 Japanese centers. The present study population consisted of 614 cancer-associated VTE patients, who were divided into 3 groups; High-risk group: 202 patients (33%) with a modified Ottawa score ≥ 1, Intermediate-risk group: 269 patients (44%) with a score = 0, and Low-risk group: 143 patients (23%) with a score ≤ -1. RESULTS: Recurrent VTE occurred in 39 patients on anticoagulation therapy within 6 months. The cumulative incidence of recurrent VTE substantially increased in the higher risk categories by the modified Ottawa score (high-risk group: 13.6% [95%CI, 8.9%-20.2%], intermediate-risk group: 5.9% [95%CI, 3.5%-9.8%], and low-risk group: 3.0% [95%CI, 1.1%-7.8%], P = .02). The discriminating power of the score was modest with a C-statistic of 0.63. Each score component of the score had a different impact on recurrent events with a variable effect size. CONCLUSIONS: The risks of recurrence in patients with cancer-associated VTE substantially increased in the higher risk categories by using the modified Ottawa score, but the discriminating power of the score for recurrence was modest with a variable impact of each score component on recurrent events.

Usefulness of Simplified Pulmonary Embolism Severity Index Score for Identification of Patients With Low-Risk Pulmonary Embolism and Active Cancer: From the COMMAND VTE Registry.

BACKGROUND: The simplified Pulmonary Embolism Severity Index (sPESI) score is a practical score for identification of patients with low-risk pulmonary embolism (PE), although it has not been applied in patients with active cancer. The current study aimed to evaluate the usefulness of the sPESI score in patients with PE and active cancer. METHODS: The COMMAND VTE Registry is a multicenter registry enrolling consecutive patients with acute symptomatic VTE. The current study population consisted of 368 patients with PE and active cancer. The 30-day clinical outcomes were compared between patients with sPESI score = 1 and patients with sPESI scores ≥ 2. RESULTS: Overall, 37 patients (10%) died during the 30 days after diagnosis. The cumulative 30-day incidences of mortality, and PE-related death, were lower in patients with sPESI score = 1 than in patients with sPESI scores ≥ 2 (6.3% vs 13.1%; log-rank P = .03; and 0.7% vs 3.9%; log-rank P = .046). Among patients with sPESI score = 1, the predominant cause of death was cancer. There were no significant differences in the cumulative 30-day incidence of recurrent VTE and major bleeding between the two groups (3.9% vs 5.6%; log-rank P = .46; and 6.4% vs 4.5%; log-rank P = .45). CONCLUSIONS: Among patients with PE and active cancer, patients with sPESI score = 1 had a lower 30-day mortality rate compared with patients with sPESI scores ≥ 2, and they showed very low PE-related mortality risk, although the overall mortality rate remained high because of cancer-related mortality. They also showed relatively high risks for recurrence and major bleeding, suggesting the need for careful follow-up.

Effect of Statins on Recurrent Venous Thromboembolism (from the COMMAND VTE Registry).

Statins, which are considered as essential for primary and secondary prevention of atherosclerotic diseases, were also reported to reduce first venous thromboembolism (VTE). However, the effect of statins on VTE recurrence remains conflicting. We aimed to examine the association between statin use and VTE recurrence in a large observational study in Japan. The COMMAND VTE Registry is a multicenter registry enrolling consecutive 3027 patients with acute symptomatic VTE in 29 centers in Japan between January 2010 and August 2014. In the current study, the entire cohort was divided into statin group (N = 437) and no-statin group (N = 2590) according to the status of statin use at baseline. The statin group as compared with the no-statin group was older (statin group 71.2 vs no-statin group 66.5 years, p <0.001), included more women (67% vs 60%, p = 0.008), and less frequently had active cancer (12% vs 25%, p <0.001). There was no significant difference in the clinical presentation of VTE (pulmonary embolism, 58% vs 56%, p = 0.44). The cumulative 3-year incidence of recurrent VTE was significantly lower in the statin group than the no-statin group (3.8% vs 8.8%, p <0.001). After adjusting for confounders including active cancer, statin use was associated with significantly lower risk for recurrent VTE (Hazard ratio 0.49, 95% confidence interval 0.29 to 0.78, p = 0.002). The results were consistent in a sensitivity sub-group analysis with and without active cancer. In conclusion, statin use was associated with significantly lower risk for the recurrent VTE in patients with VTE.

Risk of myocardial infarction in patients with psoriasis: A cross-sectional patient-population study in a Japanese hospital.

BACKGROUND: Some epidemiological studies have demonstrated the association between psoriasis vulgaris and coronary artery disease (CAD). However, there is a lack of specific data regarding the association between psoriasis vulgaris and myocardial infarction (MI), the more severe and critical presentation of CAD, in the Japanese population. METHODS AND RESULTS: We retrospectively analyzed 113,065 patients of all ages at our hospital from January 1, 2011 to January 1, 2013. We extracted the data of patients with psoriasis vulgaris, diabetes mellitus, dyslipidemia, or MI (acute, sub-acute, or old), including sex and age from the electronic medical record database. The prevalence of MI in patients with hypertension, dyslipidemia, diabetes mellitus, and psoriasis vulgaris were 4.8% (794/16,476), 5.0% (459/9236), 4.6% (531/11,555), and 2.7% (32/1197), respectively. Multivariate analysis showed that psoriasis vulgaris was significantly associated with MI [adjusted odds ratio (OR): 1.87; 95% confidence interval (CI): 1.26-2.68; p=0.0022]. In a subgroup analysis of 24,069 patients who had one or more comorbidities including diabetes mellitus, dyslipidemia, and hypertension, psoriasis vulgaris was still independently associated with MI after adjusting for sex and age (adjusted OR, 1.49; 95% CI: 1.02-2.18; p=0.0358) in adults. CONCLUSION: Psoriasis vulgaris was significantly associated with MI in a Japanese hospital-based population.
