Association of reperfusion success and emboli in new territories with long term mortality after mechanical thrombectomy

BackgroundThe degree of reperfusion is the most important modifiable predictor of 3 month functional outcome and mortality in ischemic stroke patients treated with mechanical thrombectomy. Whether the beneficial effect of reperfusion also leads to a reduction in long term mortality is unknown.MethodsPatients undergoing mechanical thrombectomy between January 2010 and December 2018 were included. The post-thrombectomy degree of reperfusion and emboli in new territories were core laboratory adjudicated. Reperfusion was evaluated according to the expanded Thrombolysis in Cerebral Infarction (eTICI) scale. Vital status was obtained from the Swiss population register. Adjusted hazard ratios (aHRs) using time split Cox regression models were calculated. Subgroup analyses were performed in patients with borderline indications.ResultsOur study included 1264 patients (median follow-up per patient 2.5 years). Patients with successful reperfusion had longer survival times, attributable to a lower hazard of death within 0–90 days and for >90 days to 2 years (aHR 0.34, 95% CI 0.26 to 0.46; aHR 0.37, 95% CI 0.22 to 0.62). This association was homogeneous across all predefined subgroups (p for interaction >0.05). Among patients with successful reperfusion, a significant difference in the hazard of death was observed between eTICI2b50 and eTICI3 (aHR 0.51, 95% CI 0.33 to 0.79). Emboli in new territories were present in 5% of patients, and were associated with increased mortality (aHR 2.3, 95% CI 1.11 to 4.86).ConclusionSuccessful, and ideally complete, reperfusion without emboli in new territories is associated with a reduction in long term mortality in patients treated with mechanical thrombectomy, and this was evident across several subgroups.

Introduction: Sepsis results in dysregulated inflammation, coagulation, and metabolism, which may contribute to increased cardiovascular disease (CVD) risk. We conducted a systematic review and meta-analysis to determine the association between sepsis and subsequent long-term CVD events. Methods: MEDLINE, Embase, and the Cochrane Controlled Trials Register and Database of Systematic Reviews were searched from inception to May 2020 to identify observational studies of adult sepsis survivors (defined by diagnostic codes or consensus definitions) measuring long-term CV outcomes. The primary outcome was a composite of myocardial infarction, CV death, and stroke. Random-effects models estimated the pooled cumulative incidence and adjusted hazard ratios of CV events relative to hospital or population controls. Odds ratios were included as risk ratios assuming <10% incidence in non-septic controls, and risk ratios were taken as hazard ratios (HR) assuming no censoring. Outcomes were analyzed at maximum follow-up (primary analysis) and stratified by time (<1 year, 1-2 years, and >2 years) since sepsis. Results: Of 11,235 abstracts screened, 25 studies (22 cohort studies, 2 case-crossover studies, and 1 case-control) involving 1,949,793 sepsis survivors were included. The pooled cumulative incidence of CVD events was 9% (95% CI; 5-14%). Sepsis was associated with an increased risk (HR 1.59, 95% CI 1.37-1.86) of CVD events at maximum follow-up ( Figure ); between-study heterogeneity was substantial (I 2 =97.3%). There was no significant difference when comparing studies using population and hospital controls. Significantly elevated risk was observed up to 5 years following sepsis. Conclusions: Sepsis survivors experience an approximately 50% increased risk of CVD events, which may persist for years following the index episode. These results highlight a potential unmet need for early cardiac risk stratification and optimization in sepsis survivors.

Long Term Mortality

Abstract Background Late left ventricular remodeling (LLVR) after the index acute myocardial infarction (AMI) is a common complication, and is associated with poor outcome. However, the optimal definition of LLVR has been debated because of its different incidence and influence on prognosis. At present, there are limited data regarding the influence of different LLVR definitions on long-term outcomes in AMI patients undergoing percutaneous coronary intervention (PCI). Purpose To explore the impact of different definitions of LLVR on long-term mortality, re-hospitalization or an urgent visit for heart failure, and identify which definition was more suitable for predicting long-term outcomes in AMI patients undergoing PCI. Methods We prospectively observed 460 consenting first-time AMI patients undergoing PCI from January 2012 to December 2018. LLVR was defined as a ≥20% increase in left ventricular end-diastolic volume (LVEDV), or a >15% increase in left ventricular end-systolic volume (LVESV) from the initial presentation to the 3–12 months follow-up, or left ventricular ejection fraction (LVEF) <50% at follow up. These parameters of the cardiac structure and function were measuring through the thoracic echocardiography. The association of LLVR with long-term prognosis was investigated by Cox regression analysis. Results The incidence rate of LLVR was 38.1% (n=171). The occurrence of LLVR according to LVESV, LVEDV and LVEF definition were 26.6% (n=117), 31.9% (n=142) and 11.5% (n=51), respectively. During a median follow-up of 2 years, after adjusting other potential risk factors, multivariable Cox regression analysis revealed LLVR of LVESV definition [hazard ratio (HR): 2.50, 95% confidence interval (CI): 1.19–5.22, P=0.015], LLVR of LVEF definition (HR: 16.46, 95% CI: 6.96–38.92, P<0.001) and LLVR of Mix definition (HR: 5.86, 95% CI: 2.45–14.04, P<0.001) were risk factors for long-term mortality, re-hospitalization or an urgent visit for heart failure. But only LLVR of LVEF definition was a risk predictor for long-term mortality (HR: 6.84, 95% CI: 1.98–23.65, P=0.002). Conclusions LLVR defined by LVESV or LVEF may be more suitable for predicting long-term mortality, re-hospitalization or an urgent visit for heart failure in AMI patients undergoing PCI. However, only LLVR defined by LVEF could be used for predicting long-term mortality. FUNDunding Acknowledgement Type of funding sources: None.

Introduction: Mortality following Transcatheter aortic valve replacement (TAVR) has been reported up to 5 years. However, mortality after 5 years remains unclear. Hypothesis: We aim to determine the mortality in patients undergoing TAVR >5 years follow up. Methods: From our institution’s prospectively collected TAVR database we analyzed all patients undergoing TAVR to a maximum follow up of 8 years. We divided our population into transapical TAVR (TA-TAVR) and transfemoral TAVR (TF-TAVR) groups. A Kaplan-Meier survival analysis was conducted. Results: A total of 511 patients who underwent TAVR were included in the analysis. Patients undergoing TA-TAVR had higher rates of peripheral vascular disease compared with TF-TAVR (56% vs 29%, p<0.001) and Society of Thoracic Surgeons Score (10.9 ± 4 vs 9.2 ± 4, p<0.001). TA-TAVR was associated with higher mortality at 1 year (32% vs 21%, p=0.01). However, there was no significant difference in very-long term mortality of patients undergoing TA-TAVR vs TF-TAVR (Figure). Conclusions: Long-term mortality following TAVR surpasses 50%. While in the first 2 years TA-TAVR is associated with higher mortality rates after three years the survival rates are similar in both approaches.

Abstract Background For recanalization of coronary chronic total occlusion (CTO) lesions, subintimal guidewire tracking in both antegrade and retrograde approaches are commonly used. Purpose This study aimed to assess the impact of subintimal tracking on long-term clinical outcomes after recanalization of CTO lesions. Methods Between January 2009 and December 2016, 474 CTO lesions (434patients) were successfully recanalized in our center. After guidewire crossing in a CTO lesion, those lesions were divided into intimal tracking group (84.6%, n=401) and subintimal tracking group (15.4%, n=73) according to intravascular ultrasound (IVUS) findings. Long-term clinical outcomes including death, target lesion revascularization (TLR), target vessel revascularization (TVR) were compared between the two groups. In addition, the rate of re-occlusion after successful revascularization was also evaluated. Results The median follow-up period was 4.7 years (interquartile range, 2.8–6.1). There was no significant difference of the rate of cardiac death between the two groups (intimal tracking vs. subintimal tracking: 7.0% vs. 4.1%; hazard ratio, 0.61; 95% confidence interval [CI], 0.19 to 2.00; p=0.41), TLR (14.3% vs. 16.2%; hazard ratio, 1.34; 95% CI, 0.71 to 2.53; p=0.37), and TVR (17.5% vs. 20.3%; hazard ratio, 1.27; 95% CI, 0.72 to 2.23; p=0.42). However, the rate of re-occlusion was significantly higher in the subintimal tracking group than intimal tracking group at 3-years re-occlusion (4.2% vs. 14.5%; log-rank test, p=0.002, Figure). In the multivariate COX regression, subintimal guidewire tracking was an independent predictor of re-occlusion after CTO recanalization (HR: 5.40; 95% CI: 2.11–13.80; p<0.001). Figure 1 Conclusions Subintimal guidewire tracking for recanalization of coronary CTO was associated with significantly higher incidence of target lesion re-occlusion during long-term follow-up period.

Background: Gender differences in outcome and its predictors in patients with acute coronary syndrome (ACS) continue to be debated. Objectives: To assess long-term mortality and explore its association with the baseline variables in women and men. Methods: We followed 2,176 consecutive patients (665 women and 1,511 men) with ACS admitted to a single hospital and still alive after 30 days for a median of 16 years 8 months. Results: At the end of the follow-up, 415 (62.4%) women and 849 (56.2%) men had died (unadjusted hazard ratio [HR] for women/men 1.18 (95% confidence interval [CI], 1.05–1.33, p =0.005). After adjustment for age, the HR was reversed to 0.88 (95% CI, 0.78–1.00, p =0.04). Additional adjustment for potential confounders yielded a HR of 0.86 (95% CI, 0.76–0.98, p = 0.02). Using multivariable Cox regression, previous heart failure, previous or new-onset atrial fibrillation, and psychotropic drugs at discharge were significantly associated with increased long-term mortality in men only. Known hypertension, elevated creatinine, and inhospital Killip class >1/cardiogenic shock were significantly associated with mortality only in women. For late mortality, hypertension and inhospital Killip class >1/cardiogenic shock interacted significantly with gender. Conclusion: For patients with ACS surviving the first 30 days, late mortality was lower in women than in men after adjusting for age. The effects of several baseline characteristics on late outcome differed between women and men. Gender-specific strategies for long-term follow-up of ACS patients should be considered.

Abstract Funding Acknowledgements Type of funding sources: None. Introduction Acute Pulmonary embolism(PE)is a common and potentially fatal medical condition.In contemporary adult population,PE is associated with increased long-term mortality. Purpose Identify predictors of long-term all-cause mortality in patients(pts)admitted due to pulmonary embolism. Methods Retrospective single-center study of hospitalized pts with acute PE between 2015 and 2018.We evaluated comorbidities, admission(AD)presentation such as vitals(with hypotension defined as systolic blood pressure(SBP)<90mmHg,and tachycardia as >100ppm),lab analyses during in-hospital period,imaging features. Mortality(long-term >3months)was also assessed using national registry of citizens.We performed uni and multivariate analysis to compare clinical characteristics of pts who died and who survived,using Cox regression and Kaplan-Meier methods.For the predictor age we assessed discrimination power and defined the best cut-off using area under the ROC curve(AUC)method. Results From 2015 to 2018,182 pts were admitted with diagnosis of pulmonary embolism,60% female with a mean age of 74 ± 13years old.Seventy-one(39%)pts died after a median follow-up of 26[10-41]months.Pts who died were older(80 ± 8 vs71 ± 14,p < 0.001).The best cut-off value of age to predict mortality with 70%sensitivity and 61%specificity was 77years old(AUC 0.703;CI95% 0.63-0.78).Pts who died had more frequently history of neoplasia (21%vs 9%,p = 0.009).The remaining comorbidities were similar in both groups.Pts who did not survive were more frequently hypotensive(28% vs 13%, p = 0.008),had higher creatinine(1.1[0.8-1.4] vs 1.0[0.8-1.2], p = 0.002), lactate(2.3[1.8-2.8]vs 1.8[1.5-2.0],p = 0.007)and NT-proBNP(4694[1498-12300]vs2070[492-6660], p < 0.001)at AD.Maximum troponin I (0.176[0.037-0.727]vs0.126[0.050-0.365]ng/mL,p = 0.012) was also higher than in pts who survived. After adjusting for history of neoplasia,ADcreatinine and maximum troponin I,we found that age (HR1.057;95%CI 1.01-1.11,p = 0.021),AD SBP < 90(HR 2.215;95%CI 1.03-4.76,p = 0.041),lactate(HR 1.17;95%CI 1.01-1.36,p = 0.035)and NT-proBNP(HR 1.510;95%CI 1.250-1.780,p < 0.001)were independent predictors of all-cause mortality. Conclusion In our cohort,the long-term all-cause mortality was 39%over a median follow-up of 26[10-41]months.In patients with pulmonary embolism,aside from already identified age(especially when ≥70 years old)and NT-proBNP,lactate should also be considered when evaluating long-term prognosis. Furthermore,hypotension at admission increases by 2fold long-term mortality in patients who suffered acute PE.

AbstractCalcium plays an essential role in physiology of the cardiovascular system. Aberrations from normal serum calcium levels are known to be associated with several cardiovascular diseases. Its possible role as a predictor for long-term mortality after acute myocardial infarction (AMI) is still uncertain. In this study, a total of 3732 patients (aged 25–74 years) with incident AMI surviving at least 28 days after AMI was included. The median follow-up time was 6.0 years. Admission total serum calcium levels were divided into quartiles. The Kaplan–Meier-Curve suggested a division of the follow up time in two different time periods. So, Cox regression models were calculated to assess association between admission serum calcium levels and all-cause long-term mortality with two observation periods: 28–2500 days and > 2500 days. The final model was adjusted for various comorbidities, clinical characteristics, in-hospital treatment and medication. The third quartile (normal-high Calcium levels) served as the reference group. The fully adjusted Cox-regression model shows significantly higher mortality risk for low serum calcium (quartile 1) within the timeframe 28–2500 days after the event (OR 1.53 [1.19–1.98]). The other groups did not differ significantly from each other. In the later observation period (from 2500 days until death or censoring) no more significant differences were seen between the four calcium quartiles. In summary, low serum calcium is an independent predictor of adverse outcome in the first 2500 days (about 7 years) after AMI. On later points in time this effect attenuates, so that no more significant differences can be observed.

Purpose. To evaluate postoperative morbidity and long term oncologic and functional outcomes of high intensity focused ultrasound (HIFU) compared to brachytherapy for the treatment of localized prostate cancer.Material and Methods. Patients treated by brachytherapy were matched 1 : 1 with patients who underwent HIFU. Differences in postoperative complications across the two groups were assessed using Wilcoxon’s rank-sum orχ2test. Kaplan-Meier curves, log-rank tests, and Cox regression models were constructed to assess differences in survival rates between the two groups.Results. Brachytherapy was significantly associated with lower voiding LUTS and less frequent acute urinary retention (p<0.05). Median oncologic follow-up was 83 months (13–123 months) in the HIFU cohort and 44 months (13–89 months) in the brachytherapy cohort. Median time to achieve PSA nadir was statistically shorter in the HIFU. Biochemical recurrence-free survival rate was significantly higher in the brachytherapy cohort compared to HIFU cohort (68.5% versus 53%,p<0.05). No statistically significant difference in metastasis-free, cancer specific, and overall survivals was observed between the two groups.Conclusion. HIFU and brachytherapy are safe with no significant difference in cancer specific survival on long term oncologic follow-up. Nonetheless, a randomized controlled trial is needed to confirm these results.

This follow-up study examines delayed mortality of children under age 5 who were exposed to measles and survived the acute phase ofthe 1714–15 epidemic in Quebec. The objective of the study was to assess whether exposed children had higher long-term mortality thanunexposed children, by following them for 25 months past the estimated date of infection. Overall, children exposed before age 3 had higher long-term mortality than unexposed children. The difference remained significant while assessing other risk factors. Delayed mortality also varied by age and sex. Only exposed female infants had a significantly higher risk of dying, while both exposed male and female toddlers had higher mortality. No significant difference was found among children exposed after age 3. Findings are explained in terms of modern post-measles studies in Africa and of previous measles studies in New France.

Abstract BACKGROUND Adding intensive-procarbazine, lomustine, and vincristine (iPCV) to radiotherapy (RT) prolonged progression-free (PFS) and overall survival (OS) for patients with 1p19q codeleted anaplastic oligodendroglial tumors (AOTs); some benefit was also observed for IDH-mutant non-codeleted cases (Cairncross et al 2013, 2014, 2016). Now, 25 years after study activation, we updated survival, further assessed IDH as a predictive biomarker, and are exploring the benefit from vincristine. METHODS Eligible adults (KPS ≥ 60, adequate end-organ function) were randomized to pre-RT iPCV (4 cycles x 6 weeks each) vs. RT alone, stratified by age (< or ≥ 50), KPS (60–70 or ≥ 80), and level of anaplasia. Histology (anaplastic oligodendroglioma/oligo-astrocytoma required) and biomarkers (IDH and 1p19q, post-hoc) were determined centrally. Survival was estimated by Kaplan-Meier and Hazard Ratios (HRs) by Cox-regression. RESULTS Overall (n=289), median follow-up was 16.4 years vs. 11.3 years at last report. In codeleted cases, 40% randomized to iPCV remained alive vs. 53% at last report; 5, 10, and 14 year-PFS and -OS rates were 62%, 50%, 41% and 70%, 57%, 46%, respectively; and iPCV unequivocally prolonged PFS (median 9.8 vs. 2.9 years, HR 0.46, 95% CI 0.3–0.7, p< 0.001) and OS (median 13.2 vs. 7.3 years, HR 0.61, 95% CI 0.40–0.94; p=0.02). With IDH mutation but without codeletion (n=66), iPCV prolonged PFS (median 2.8 vs. 1.9 years, HR 0.58, 95% CI 0.34–0.99, p=0.046); OS was longer with a trend for significance (median 5.5 vs. 3.3 years, HR 0.6, 95% CI 0.34–1.03, p=0.06) on this underpowered exploratory post-hoc analysis. CONCLUSION For codeleted AOTs, long-term analyses confirmed that pre-RT iPCV produced meaningful and significant prolongations of PFS and OS. With IDH mutation but without codeletion, iPCV significantly prolonged PFS and showed a trend for prolonged OS. The value of vincristine is being assessed.
