Abstract Background Our previous study showed that elevated D-dimer (D-D) level after 1 month of the anticoagulant therapy was an independent predictor of deep vein thrombosis (DVT) recurrences and combined endpoint (DVT recurrence and/or death from any causes) during 18 months. Prognostic value of elevated D-D level after 1 month of the anticoagulant therapy for the long-term venous thromboembolism (VTE) outcomes is unknown. Purpose To estimate the elevated D-D level influence after 1 month of the anticoagulant therapy on the 10-year prognosis in VTE pts. Methods One hundred and twelve pts (77 men) aged 18–76 (mean 54±14) years with DVT and/or pulmonary embolism were included in the study. Pts received unfractionated or low molecular weight heparin for at least 5 days followed by the long-term warfarin therapy (target international normalized ratio 2,0–3,0). D-D level was measured after 1 month from the start of the anticoagulant therapy by a quantitative assay with an estimated cut-off level of 0,5 ug/ml. The follow-up period was 10 years. Endpoints were VTE recurrence and combined endpoint (VTE recurrence and/or death from any causes). Results In all pts, median of follow-up was 2,77 years (min 2 weeks, max 11,61 years, IQR 1,44 to 10,31 years). Seventy seven (69%) pts had ended the 10-year follow-up period completely or achieved the endpoint. In these pts, median of follow-up was 9,23 years (IQR 1,70 to 10,53 years). Thirty-five cases were censored. During 10 years, the VTE recurrences rate was 27,7%, 14 pts died, the combined endpoint rate was 36,6%. Kaplan-Meier analysis showed that pts with elevated D-D level after 1 month of the anticoagulant therapy had higher 10-year cumulative risk for adverse outcomes (chi-square=6,0, p=0,014 for VTE recurrence; chi-square=13,7, p<0,001 for combined endpoint). Cox regression confirmed that elevated D-D level after 1 month of the anticoagulant therapy was associated with a 2,5-fold increase in the 10-year VTE recurrences risk (HR 2,52; 95% CI 1,18–5,42; p=0,018) and a 3,2-fold increase in the 10-year combined endpoint risk (HR 3,21; 95% CI 1,68–6,15; p<0,001) compared pts with normal D-D level after 1 month of the anticoagulant therapy. Conclusions During 10 years, the VTE recurrences rate was 27,7%, combined endpoint rate (VTE recurrence and/or death from any causes) was 36,6%. Elevated (>0,5 ug/ml) D-D level after 1 month of the anticoagulant therapy had a prognostic value and was associated with the 2,5-fold increase in the 10-year VTE recurrences risk and the 3,2-fold increase in the 10-year adverse outcomes risk.

Background: There are few data on the long-term risk of venous thromboembolism (VTE) among stroke survivors. We aimed to compare the incidence of VTE amongst patients with ischemic stroke versus those with intracerebral hemorrhage (ICH). Methods: We identified all adults discharged from nonfederal acute care hospitals in CA, NY, and FL between 2005 and 2012 with previously validated ICD-9-CM codes for ischemic stroke and ICH. Our primary outcome of VTE was defined as pulmonary embolism or deep vein thrombosis. To capture incident cases of VTE, we excluded patients with a VTE prior to or during the index stroke. Kaplan-Meier survival statistics were used to calculate the cumulative rate of incident VTE. Cox regression was used to compare the risk of VTE after stroke while adjusting for demographics, vascular risk factors, and Elixhauser comorbidity index. As there was a violation of the proportional-hazards assumption, we calculated separate hazard ratios (HR) for each year of follow-up. Results: We identified 834,660 patients with stroke, of whom 712,440 (85.3%) had ischemic stroke and 112,220 (14.7%) had ICH. Over a mean follow-up of 2.8 (+/-2.4) years, 19,937 (2.4%) developed VTE. After 7 years, the cumulative rate of VTE was 4.7% (95% confidence interval [CI], 4.5-4.9%) in patients with ICH and 4.4% (95% CI, 4.3-4.5%) in patients with ischemic stroke. In multivariable analysis, VTE risk was higher in the first year after ICH compared to ischemic stroke (HR 1.51; 95% CI, 1.43-1.58). However, following the first year, the hazard of VTE was higher among patients with ischemic stroke versus those with ICH (Figure). Conclusions: The risk of VTE after stroke varies by stroke type and time. Patients with ICH have a higher risk of VTE in the first year after stroke as compared to those with ischemic stroke while patients with ischemic stroke have a higher risk beyond 1 year.

The role of activation of the coagulation and fibrinolysis system in the pathogenesis and prognosis of cardiovascular diseases (CVDs) has drawn wide attention. Recently, the D-dimer to fibrinogen ratio (DFR) is considered as a useful biomarker for the diagnosis and prognosis of ischemic stroke and pulmonary embolism. However, few studies have explored the relationship between DFR and cardiovascular disease. In our study, patients were divided into 2 groups according to DFR value: the lower group (DFR < 0.52, n = 2123) and the higher group (DFR ≥ 0.52, n = 1073). The primary outcome was all-cause mortality (ACM) and cardiac mortality (CM). The average follow-up time was 37.59 ± 22.24 months. We found that there were significant differences between the 2 groups in term of ACM (2.4% vs 6.6%, P < 0.001) and CM (1.5% vs 4.0%, P < 0.001). Kaplan–Meier analyses showed that elevated DFR had higher incidences of ACM (log rank P < 0.001) and CM (log rank P < 0.001). Multivariate Cox regression analyses showed that DFR was an independent predictor of ACM (HR = 1.743, 95%CI: 1.187-2.559 P = 0.005) and CM (HR = 1.695, 95%CI: 1.033-2.781 P = 0.037). This study indicates that DFR is an independent and novel predictor of long-term ACM and CM in post-PCI patients with CAD.

Abstract Introduction Heart failure (HF) is a well-known risk factor for atrial fibrillation (AF). Moreover, HF is associated with worse clinical outcomes in patients with known AF. Recently, phenotypes of HF have been redefined according to the level of ejection fraction (EF). New data are needed to understand if a differential risk for outcomes exists according to the new phenotypes' definitions. Purpose To evaluate the risk of major adverse outcomes in patients with AF and HF according to HF clinical phenotypes. Methods We performed a subgroup analysis of AF patients enrolled in the EORP-AF Long-Term General Registry with a history of HF at baseline, available EF and follow-up data. Patients were categorized as follows: i) EF<40%, i.e. HF reduced EF [HFrEF]; ii) EF 40–49%, i.e. HF mid-range EF [HFmrEF]; iii) EF ≥50%, i.e. HF preserved EF [HFpEF]. Any thromboembolic event (TE)/acute coronary syndrome (ACS)/cardiovascular (CV) death, CV death and all-cause death were recorded. Results A total of 3409 patients were included in this analysis: of these, 907 (26.6%) had HFrEF, 779 (22.9%) had HFmrEF and 1723 (50.5%) had HFpEF. An increasing proportion with CHA2DS2-VASc ≥2 was found across the three groups: 90.4% in HFrEF, 94.6% in HFmrEF and 97.3% in HFpEF (p<0.001), while lower proportions of HAS-BLED ≥3 were seen (28.0% in HFrEF, 26.3% in HFmrEF and 23.6% in HFpEF, p=0.035). At discharge patients with HFpEF were less likely treated with antiplatelet drugs (22.0%) compared to other classes and were less prescribed with vitamin K antagonists (VKA) (57.0%) and with any oral anticoagulant (OAC) (85.7%). No differences were found in terms of non-vitamin K antagonist oral anticoagulant use. At 1-year follow-up, a progressively lower rate for all study outcomes (all p<0.001), with an increasing cumulative survival, was found across the three groups, with patients with HFpEF having better survival (all p<0.0001 for Kaplan-Meier curves). After full adjustment, Cox regression analysis showed that compared to HFrEF, HFmrEF and HFpEF were associated with risk of all study outcomes (Table). Cox Regression Analysis HR (95% CI) Any TE/ACS/CV Death CV Death All-Cause Death HFmrEF 0.65 (0.49–0.86) 0.53 (0.38–0.74) 0.55 (0.41–0.74) HFpEF 0.50 (0.39–0.64) 0.42 (0.31–0.56) 0.45 (0.35–0.59) ACS = Acute Coronary Syndrome; CI = Confidence Interval; CV = Cardiovascular; EF = Ejection Fraction; HF = Heart Failure; HR = Hazard Ratio. Conclusions In this cohort of AF patients with HF, HFpEF was the most common phenotype, being associated with a profile related to an increased thromboembolic risk. Compared to HFrEF, both HFmrEF and HFpEF were associated with a lower risk of all major adverse outcomes in AF patients.

SummaryVenous thromboembolism (VTE) is a frequent complication of malignancy. The aim of this study was to investigate whether multi-state modelling may be a useful quantitative approach to dissect the complex epidemiological relationship between hypercoagulability, VTE, and death in cancer patients. We implemented a three-state/three-transition unidirectional illness-death model of cancer-associated VTE in data of 1,685 cancer patients included in a prospective cohort study, the Vienna Cancer and Thrombosis Study (CATS). During the two-year follow-up period, 145 (8.6%) patients developed VTE, 79 (54.5%) died after developing VTE, and 647 (38.4%) died without developing VTE, respectively. VTE events during follow-up were associated with a three-fold increase in the risk of death (Transition Hazard ratio (HR)=2.98, 95% confidence interval [CI]: 2.36-3.77, p< 0.001). This observation was independent of cancer stage. VTE events that occurred later during follow-up exerted a stronger impact on the risk of death than VTE events that occurred at earlier time points (HR for VTE occurrence one year after baseline vs at baseline=2.30, 95% CI: 1.28-4.15, p=0.005). Elevated baseline D-dimer levels emerged as a VTE-independent risk factor for mortality (HR=1.07, 95% CI: 1.05-1.08, p< 0.001), and also predicted mortality risk in patients who developed VTE. A higher Khorana Score predicted both the risk for VTE and death, but did not predict mortality after cancer-associated VTE. In conclusion, multi-state modeling represents a very potent approach to time-to-VTE cohort data in the cancer population, and should be used for both observational and interventional studies on cancer-associated VTE.

Abstract Background and aims: This study investigates the long-term prognostic value of homocysteine in patients with acute coronary syndrome complicated with hypertension. Methods:The current work is a multicenter, retrospective, observational cohort study. We consecutively enrolled 1288 ACS patients hospitalized in 11 general hospitals in Chengdu, China, from June 2015 to December 2019. The patients were divided into hypertension and non-hypertension groups, and each was further classified into hyperhomocysteinemia (H-Hcy) and normal homocysteinemia (N-Hcy) groups according to the cut-off value of homocysteine predicting long-term mortality during follow-up. In both groups, we used Kaplan-Meier and multivariate Cox regression analysis to assess the relationship between homocysteine and long-term prognosis. Results: The median follow-up time was 18 months (range: 13.83-22.37). During this period, 78 (6.05%) death cases were recorded. The hypertension was further divided into H-Hcy (n=245) and N-Hcy (n=543), with an optimal cut-off value of 16.81 µmol/L. Similarly, non-hypertension was further divided into H-Hcy (n=200) and N-Hcy (n=300), with an optimal cut-off value of 14 µmol/L. Kaplan-Meier survival curves revealed that H-Hcy had a significantly lower survival probability than N-Hcy, both in hypertension and non-hypertension (P-value<0.01). After adjusting for confounding factors, multivariate Cox regression analysis revealed that H-Hcy (HR=2.1923, 95% CI: 1.213-3.9625, P＜0.01) was an independent predictor of long-term all-cause death in ACS with hypertension, but not in non-hypertension.Conclusion: Elevated homocysteine level predicts risk of all-cause mortality in ACS with hypertension, but not in those without hypertension. it should be considered when determining risk stratification for ACS, particularly those complicating hypertension.

Abstract Background: Risk assessment is essential for the primary prevention of cardiovascular death among general population. Although studies have shown that waist circumference (WC) is positively associated with an increased risk of cardiovascular death among the general population, few studies have investigated the prognostic value of WC during a long-term follow up and the risk threshold of WC remains controversial. We aimed to investigate whether higher level of WC measurements was able to predict mortality in general population.Methods: In this prospective cohort study, a total of 1521 consecutive subjects free of clinical cardiovascular disease were included. The end point was cardiovascular death. The Kaplan-Meier method was used to evaluate the cumulative risk of outcome at different WC levels, and compared by log-rank tests. Univariate and multivariable-adjusted Cox regression models were used to investigate the association between WC and outcomes.Results: During a median follow up of 9.2 years, there were 265 patients died. Kaplan-Meier survival estimates indicated that the patients with higher levels of WC (WC> 94cm) had a significantly increased risk of cardiovascular death (log-rank p＜0.001). After adjustment for potential confounders, multiple COX regression models showed that higher level of WC was an independent predictor in developing cardiovascular death (HR 3.02; 95% CI: 1.88–3.83; p＜0.001). We saw a significant increase of (area under the curve) AUC in ROC (receiver operating characteristic) curve after addition of WC to a clinical model, for long-term cardiovascular death the increase of AUC 0.766 vs 0.642 (95% CI: 0.787–0.846 p＜0.001). The addition of WC to established risk factors significantly improved risk prediction of cardiovascular death (net reclassification index, and integrated discrimination improvement, all p＜0.05).Conclusion: Higher level of WC is significantly associated with long-term cardiovascular death. WC may provide incremental prognostic value beyond traditional risks factors.

Abstract Introduction Serum lactate is a marker for the presence and severity of imbalances between tissue oxygen supply and demand. There are only scare data regarding the significance of arterial lactate in PE patients. Purpose We sought to explore the significance of venous serum lactate as a short- and long-term predictor of adverse outcomes. Methods We prospectively enrolled 570 patients with topographically-confirmed pulmonary embolism, hospitalized in our center during 2016–2019. Patient's data was collected using an electronic medical record and follow-up interviews via telephone. The combined end point of hemodynamic instability, shock, mechanical ventilation, or need for CPR was prospectively documented during hospitalization as well as 1-year mortality. Results The analysis included 461 consecutive patients with available clinical data including venous lactate. The median age was 69 years, and 262 (58%) were female. Median serum lactate levels were 21 mg/dL (IQR 16–31). The composite endpoint was documented in 92 patients (20%), and lactate levels above 21 mg/dl had a higher incidence of the composite end point (26% vs, 14%, p=0.002). Similar findings were seen when adding either the need for escalating therapy (44% vs. 24%, p&lt;0.001), in-hospital mortality (31% vs. 16%, p=0.001) or 30-day mortality (27% vs. 21%, p&lt;0.001) to the previous composite. One-year mortality was significantly higher in the higher lactate group (17% vs 5%, p&lt;0.001), and a lactate level above 21 mg/dL was independently associated with 1-year mortality in a Cox-regression model adjusted for age, gender and a history of heart failure or malignancy, HR 2.5 (95% CI 1.7–3.9). In subgroup analyses, lactate levels were associated with 1-year mortality regardless of age or gender. Similar predictive trends for 1-year mortality were seen in patients stratified by diabetes status, a current malignancy, PE risk and right-ventricle abnormalities (see figure). Conclusions Venous serum lactate levels are associated with a myriad of in-hospital adverse outcomes, as well as long-term mortality. In a 1-year follow-up, a higher lactate level was predictive of mortality across various subgroups, with higher hazard ratios seen specifically in lower-risk patients. Further studies are needed in order to evaluate the possible prognostic role of the change in serum lactate during PE management.

Myocardial infarction with non-obstructive coronary arteries (MINOCA) is a heterogeneous entity with an inflammatory etiopathogenesis. This study investigated the prognostic value of the neutrophil-to-lymphocyte ratio (NLR) in patients with MINOCA. Coronary angiographies performed between June 2015 and August 2018 were analyzed retrospectively and included 72 patients with MINOCA and 248 controls with normal coronary angiograms. The predictors of mortality were determined by univariate Cox regression analysis. The mean age of the subjects was 46 ± 9 years, and 176 (55%) were female. Median follow-up was 21 (max: 42) months. Neutrophil-to-lymphocyte ratio was significantly higher in the MINOCA group than in the controls ( P < .01). During long-term follow-up, the number of deaths was 6 in the MINOCA group and none in the control patients ( P < .01). Univariate Cox regression analysis revealed that the NLR (hazard ratio: 1.24, 95% confidence interval: 1.09-1.41, P = .001) was a predictor of mortality in patients with MINOCA. Kaplan–Meier analysis also showed that patients with MINOCA had relatively higher mortality rate (long-rank test; P < .01). In conclusion, the NLR is significantly higher in patients with MINOCA compared with controls, and it is a predictor of long-term mortality.

Abstract Funding Acknowledgements Type of funding sources: None. BACKGROUND While the benefit of coronary revascularization in patients with stable coronary artery disease (CAD) is debated, data assessing the potential interest of stress CMR to guide coronary revascularization are limited. PURPOSE To assess the long-term prognostic value of stress CMR-related coronary revascularization in consecutive patients from a large registry. METHODS Between 2008 and 2018, a retrospective cohort study with a median follow-up of 6.0 years (interquartile range: 5.0-8.0) included all consecutive patients referred for stress CMR. Stress CMR-related coronary revascularization was defined by any coronary revascularization performed within 90 days after CMR. The primary outcome was all-cause death based on the electronic National Death Registry. RESULTS Among the 31,752 consecutive patients (mean age 63.7 ± 12.1 years and 65.7% males), 2,679 (8.4%) died at 206,453 patient-years of follow-up. Inducible ischemia and late gadolinium enhancement (LGE) by CMR were associated with death (both p &lt; 0.001). In multivariable Cox regression, inducible ischemia and LGE were independent predictors of death (HR = 1.61; 99.5%CI 1.41-1.84; HR = 1.62; 99.5%CI 1.41-1.86, respectively; p &lt; 0.001). CMR-related coronary revascularization was an independent predictor of greater survival (HR: 0.66; 99.5%CI: 0.52-0.84; p &lt; 0.001). CMR-related revascularization was associated with a lower incidence of death in patients with severe inducible ischemia (p &lt; 0.001), but showed no benefit in patients with mild or moderate ischemia (p = 0.109). CONCLUSIONS In this large observational series of consecutive patients, stress perfusion CMR had important incremental long-term prognostic value to predict death over traditional risk factors. CMR-related revascularization was associated with a lower incidence of death in patients with severe ischemia.
