    Abstract: Although statins are effective in secondary prevention of ischemic stroke, they are also associated with an increase risk of intracranial hemorrhage (ICH) in certain conditions. In the TST trial (Treat Stroke to Target), we prespecified an exploration of the predictors of incident ICH. Methods: Patients with ischemic stroke in the previous 3 months or transient ischemic attack within the previous 15 days and evidence of cerebrovascular or coronary artery atherosclerosis were randomly assigned in a 1:1 ratio to a target LDL (low-density lipoprotein) cholesterol of 〈 70 mg/dL or 100±10 mg/dL, using statin or ezetimibe. Results: Among 2860 patients enrolled, 31 incident ICH occurred over a median follow-up of 3 years (18 and 13 in the lower and higher target group, 3.21/1000 patient-years [95% CI, 2.38–4.04] and 2.32/1000 patient-years [95% CI, 1.61–3.03] , respectively). While there were no baseline predictors of ICH, uncontrolled hypertension (HR, 2.51 [95% CI, 1.01–6.31], P =0.041) and being on anticoagulant (HR, 2.36 [95% CI, 1.00–5.62], P =0.047)] during the trial were significant predictors. On-treatment low LDL cholesterol was not a predictor of ICH. Conclusions: Targeting an LDL cholesterol of 〈 70 mg/dL compared with 100±10 mg/dL in patients with atherosclerotic ischemic stroke nonsignificantly increased the risk of ICH. Incident ICHs were not associated with low LDL cholesterol. Uncontrolled hypertension and anticoagulant therapy were associated with ICH which has important clinical implications.

    Abstract: The TST trial (Treat Stroke to Target) evaluated the benefit of targeting a LDL (low-density lipoprotein) cholesterol of 〈 70 mg/dL to reduce the risk of cardiovascular events in 2860 patients with ischemic stroke with atherosclerotic stenosis of cerebral vasculature or aortic arch plaque 〉 4 mm, in a French and Korean population. The follow-up lasted a median of 5.3 years in French patients (similar to the median follow-up time in the SPARCL trial [Stroke Prevention by Aggressive Reduction in Cholesterol Level]) and 2.0 years in Korean patients. Exposure duration to statin is a well-known driver for cardiovascular risk reduction. We report here the TST results in the French cohort. Methods— One thousand seventy-three French patients were assigned to 〈 70 mg/dL (1.8 mmol/L) and 1075 to 100±10 mg/dL (90–110 mg/dL, 2.3–2.8 mmol/L). To achieve these goals, investigators used the statin and dosage of their choice and added ezetimibe on top if needed. The primary outcome was the composite of ischemic stroke, myocardial infarction, new symptoms requiring urgent coronary or carotid revascularization and vascular death. Results— After a median follow-up of 5.3 years, the achieved LDL cholesterol was 66 (1.69 mmol/L) and 96 mg/dL (2.46 mmol/L) on average, respectively. The primary end point occurred in 9.6% and 12.9% of patients, respectively (HR, 0.74 [95% CI, 0.57–0.94]; P =0.019). Cerebral infarction or urgent carotid revascularization following transient ischemic attack was reduced by 27% ( P =0.046). Cerebral infarction or intracranial hemorrhage was reduced by 28% ( P =0.023). The primary outcome or intracranial hemorrhage was reduced by 25% ( P =0.021). Intracranial hemorrhages occurred in 13 and 11 patients, respectively (HR, 1.17 [95% CI, 0.53–2.62]; P =0.70). Conclusions— After an ischemic stroke of documented atherosclerotic origin, targeting a LDL cholesterol of 〈 70 mg/dL during 5.3 years avoided 1 subsequent major vascular event in 4 (number needed to treat of 30) and no increase in intracranial hemorrhage.

    Abstract: Whether a strategy to target an LDL (low-density lipoprotein) cholesterol 〈 70 mg/dL is more effective when LDL is reduced 〉 50% from baseline rather than 〈 50% from baseline has not been investigated. METHODS: The Treat Stroke to Target trial was conducted in France and South Korea in 61 sites between March 2010 and December 2018. Patients with ischemic stroke in the previous 3 months or transient ischemic attack within the previous 15 days and evidence of cerebrovascular or coronary artery atherosclerosis were randomly assigned to a target LDL cholesterol of 〈 70 mg/dL or 100±10 mg/dL, using statin and/or ezetimibe as needed. We used the results of repeated LDL measurements (median, 5 [2–6] per patient) during 3.9 years (interquartile range, 2.1–6.8) of follow-up. The primary outcome was the composite of ischemic stroke, myocardial infarction, new symptoms requiring urgent coronary or carotid revascularization, and vascular death. Cox regression model including lipid-lowering therapy as a time-varying variable, after adjustment for randomization strategy, age, sex, index event (stroke or transient ischemic attack), and time since the index event. RESULTS: Among 2860 patients enrolled, patients in the lower target group who had 〉 50% LDL cholesterol reduction from baseline during the trial had a higher baseline LDL cholesterol and a lower LDL cholesterol achieved as compared to patients who had 〈 50% LDL cholesterol reduction (155±32 and 62 mg/dL versus 121±34 and 74 mg/dL, respectively, P 〈 0.001 for both). In the 〈 70 mg/dL target group, patients with 〉 50% LDL reduction had a significant reduction in the primary outcome as compared to the higher target group (hazard ratio, 0.61 [95% CI, 0.43–0.88]; P =0.007) and patients with 〈 50% LDL reduction from baseline had little reduction (hazard ratio, 0.96 [95% CI, 0.73–1.26]; P =0.75). CONCLUSIONS: In this post hoc analysis of the TST trial, targeting an LDL cholesterol of 〈 70 mg/dL reduced the risk of primary outcome compared with 100±10 mg/dL provided LDL cholesterol reduction from baseline was superior to 50%, thereby suggesting that the magnitude of LDL cholesterol reduction was as important to consider as the target level to achieve.

    Abstract: It is unknown whether the direct oral anticoagulant edoxaban can reduce leaflet thrombosis and the accompanying cerebral thromboembolic risk after transcatheter aortic valve replacement. In addition, the causal relationship of subclinical leaflet thrombosis with cerebral thromboembolism and neurological or neurocognitive dysfunction remains unclear. Methods: We conducted a multicenter, open-label randomized trial comparing edoxaban with dual antiplatelet therapy (aspirin plus clopidogrel) in patients who had undergone successful transcatheter aortic valve replacement and did not have an indication for anticoagulation. The primary end point was an incidence of leaflet thrombosis on 4-dimensional computed tomography at 6 months. Key secondary end points were the number and volume of new cerebral lesions on brain magnetic resonance imaging and the serial changes of neurological and neurocognitive function between 6 months and immediately after transcatheter aortic valve replacement. Results: A total of 229 patients were included in the final intention-to-treat population. There was a trend toward a lower incidence of leaflet thrombosis in the edoxaban group compared with the dual antiplatelet therapy group (9.8% versus 18.4%; absolute difference, −8.5% [95% CI, −17.8% to 0.8%]; P =0.076). The percentage of patients with new cerebral lesions on brain magnetic resonance imaging (edoxaban versus dual antiplatelet therapy, 25.0% versus 20.2%; difference, 4.8%; 95% CI, −6.4% to 16.0%) and median total new lesion number and volume were not different between the 2 groups. In addition, the percentages of patients with worsening of neurological and neurocognitive function were not different between the groups. The incidence of any or major bleeding events was not different between the 2 groups. We found no significant association between the presence or extent of leaflet thrombosis with new cerebral lesions and a change of neurological or neurocognitive function. Conclusions: In patients without an indication for long-term anticoagulation after successful transcatheter aortic valve replacement, the incidence of leaflet thrombosis was numerically lower with edoxaban than with dual antiplatelet therapy, but this was not statistically significant. The effects on new cerebral thromboembolism and neurological or neurocognitive function were also not different between the 2 groups. Because the study was underpowered, the results should be considered hypothesis generating, highlighting the need for further research. Registration: URL: https://www.clinicaltrials.gov .

    Abstract: Introduction: Statins reduce major cardiovascular events, but residual risk remains. The study examined determinants of atherosclerotic statin non-response in patients using statins. Hypothesis: We hypothesized that a comprehensive evaluation of atherosclerosis identifies patients that progress atherosclerosis despite the use of statin therapy. Methods: The multi-center PARADIGM registry included patients who underwent serial CCTA ≥2 years apart, with whole-heart coronary tree quantification of vessel, lumen and plaque, and matching of baseline and follow-up coronary segments and lesions. Patients with statin use at baseline and follow-up CCTA were included. Atherosclerotic statin non-response was defined as an absolute increase in percent atheroma volume (PAV) of 1.0% or more per year. A secondary endpoint was defined by the additional requirement of progression of low-attenuation plaque or fibro-fatty plaque. Results: We included 649 patients (62.0±9.0 years, 63.5% male) on statin therapy and 205 (31.5%) experienced atherosclerotic statin non-response. Age, diabetes, hypertension, and all atherosclerotic plaque features (high risk plaque [HRP] features, calcified and noncalcified PAV, and lumen volume) were significantly different between patients with and without atherosclerotic statin non response, while only diabetes, the number of high risk plaque features, noncalcified and calcified PAV were independently associated with atherosclerotic statin non-response (OR:1.41 (0.95-2.11), OR:1.15 (1.09-1.21), OR:1.06 (1.02-1.10), OR:1.07 (1.03-1.12), respectively). For the secondary endpoint (N=125, 19.2%), only non-calcified PAV and number of HRP features were the independent determinants (OR:1.08 (1.03-1.13) and OR:1.21 (1.06-1.21), respectively). Conclusions: In patients treated with statins, baseline plaque characterization by plaque burden and high risk plaque is associated with atherosclerotic statin non-response defined as important progression of coronary atherosclerosis. Patients with the highest plaque burden including HRP were at highest risk for plaque progression, despite statin therapy. These patients may need additional therapies for further risk reduction.

    Abstract: Rapid coronary plaque progression (RPP) is associated with incident cardiovascular events. To date, no method exists for the identification of individuals at risk of RPP at a single point in time. This study integrated coronary computed tomography angiography–determined qualitative and quantitative plaque features within a machine learning (ML) framework to determine its performance for predicting RPP. Methods and Results Qualitative and quantitative coronary computed tomography angiography plaque characterization was performed in 1083 patients who underwent serial coronary computed tomography angiography from the PARADIGM (Progression of Atherosclerotic Plaque Determined by Computed Tomographic Angiography Imaging) registry. RPP was defined as an annual progression of percentage atheroma volume ≥1.0%. We employed the following ML models: model 1, clinical variables; model 2, model 1 plus qualitative plaque features; model 3, model 2 plus quantitative plaque features. ML models were compared with the atherosclerotic cardiovascular disease risk score, Duke coronary artery disease score, and a logistic regression statistical model. 224 patients (21%) were identified as RPP. Feature selection in ML identifies that quantitative computed tomography variables were higher‐ranking features, followed by qualitative computed tomography variables and clinical/laboratory variables. ML model 3 exhibited the highest discriminatory performance to identify individuals who would experience RPP when compared with atherosclerotic cardiovascular disease risk score, the other ML models, and the statistical model (area under the receiver operating characteristic curve in ML model 3, 0.83 [95% CI 0.78–0.89], versus atherosclerotic cardiovascular disease risk score, 0.60 [0.52–0.67] ; Duke coronary artery disease score, 0.74 [0.68–0.79]; ML model 1, 0.62 [0.55–0.69] ; ML model 2, 0.73 [0.67–0.80]; all P 〈 0.001; statistical model, 0.81 [0.75–0.87], P =0.128). Conclusions Based on a ML framework, quantitative atherosclerosis characterization has been shown to be the most important feature when compared with clinical, laboratory, and qualitative measures in identifying patients at risk of RPP.

    Abstract: Coronavirus disease 2019 (COVID-19) is mainly an infectious disease of the respiratory system transmitted through air droplets, and pulmonary symptoms constitute main presentations of this disease. However, COVID-19 demonstrates a clinically diverse manifestation ranging from asymptomatic presentation to critically illness with severe pneumonia, acute respiratory distress syndrome, respiratory failure, or multiple organ failure. Accumulating evidences demonstrated that COVID-19 has extrapulmonary involvement, including neurological, smelling sensation, cardiovascular, digestive, hepatobiliary, renal, endocrinologic, dermatologic system, and others. Over a third of COVID-19 patients manifest a wide range of neurological symptoms involving the central/peripheral nervous system. Underlying cardiovascular comorbidities were associated with detrimental outcomes, meanwhile the occurrence of cardiovascular complications correlate to poor survival. Gastrointestinal symptoms frequently occur and have been associated with a longer period of illness. Impaired hepatic functions were associated with the severity of the disease. Higher rate of acute kidney injury was reported in critically ill patients with COVID-19. Endocrinologic presentations of COVID-19 include exacerbating hyperglycemia, euglycemic ketosis, and diabetic ketoacidosis. The most common cutaneous manifestation was acro-cutaneous (pernio or chilblain-like) lesions, and other skin lesions consist of maculopapular rash, vesicular lesions, livedoid/necrotic lesions, exanthematous rashes, and petechiae. This review article summarized the general clinical signs and symptoms, radiologic features, and disease manifestation with progression in patients with COVID-19.

    Abstract: Thrombotic microangiopathy (TMA) syndromes are extraordinarily diverse in clinical presentations and etiologies. However, there are still a limited number of large cohort studies focusing on the underlying causes, outcomes, and response to plasmapheresis. A retrospective study was designed to understand trigger etiologies, organ dysfunctions, clinical outcomes, and efficacy of plasmapheresis in patients with TMA. The whole population of Taiwan was set up into 2 cohorts: 875 patients with TMA in the 2006 cohort (2006–2010) and 1352 patients with TMA in the 2011 cohort (2011–2015). One hundred ninety-five patients in the 2006 cohort and 272 patients in the 2011 cohort were under plasmapheresis treatment. The common underlying etiologies were pregnancy, followed by systemic lupus erythematosus, rheumatoid arthritis, transplantation and drugs, which were significantly higher than the control group. Stroke, seizure, arterial thrombosis, vascular stenosis, hypertension, myocardial infarction, and pancreatitis were the main clinical signs and extra-renal involvements. In the multivariate regression analysis, stroke, arterial thrombosis, peripheral arterial disease, and uremia were significantly higher compared with the control group. The mortality rate in TMA under plasmapheresis was significantly higher than all TMA cases (39.33% vs 15.39% in the 2006 cohort and 39.27% vs 15.06% in the 2011 cohort). This study indicated the spectrum of underlying causes, extra-renal characteristics, and the response to plasmapheresis of patients with TMA in Taiwan. Of note, the poor clinical outcomes of plasmapheresis in patients with TMA might highlight the masked underlying etiology or worse disease condition that should be noticed.

    Abstract: Surgical stress and pain are potential provoking factors for postoperative myasthenic crisis (POMC). We report the occurrence of early POMC and late deep vein thrombosis (DVT) in a man with myasthenia gravis (MG) undergoing thymectomy, addressing possible link between reversal of opioid overdose with naloxone and the triggering of POMC. Patient concerns: A 71-year-old man with impaired renal function (ie, estimated glomerular filtration rate [egfr]: 49.1 mL/min/1.73 m 2 ) with diagnosis of MG made 2 months ago was scheduled for thymectomy. After uncomplicated surgery, he experienced opioid overdose that was treated with naloxone. Hyperlactatemia then developed with a concomitant episode of hypertension. Three hours after reversal, he suffered from myasthenic crisis presenting with respiratory failure and difficult weaning from mechanical ventilation. Diagnosis: Stress-induced hyperlactatemia and subsequent myasthenic crisis Interventions: Pyridostigmine and immunosuppressive therapy with prednisolone were initiated. Hyperlactatemia subsided on postoperative day (POD) 5. Tracheal extubation was performed successfully on POD 6. Outcomes: During the course of hospitalization, his eGFR (ie, 88.9 mL/min/1.73 m 2 ) was found to improve postoperatively. After discharge from hospital, he developed DVT in the left femoral and popliteal veins on POD 24 when he was readmitted for immediate treatment with low-molecular-weight heparin. He was discharged without sequelae on POD 31. There was no recurrence of myasthenic crisis or DVT at 3-month follow-up. Conclusions: Following naloxone administration, hyperlactatemia may be an indicator of pain-related stress response, which is a potential provoking factor for myasthenic crisis. Additionally, patients with MG may have an increased risk of DVT possibly attributable to immune-mediated inflammation. These findings highlight the importance of perioperative avoidance of provoking factors including monitoring of stress-induced elevations in serum lactate concentration, close postoperative surveying for myasthenic crisis, and early recognition of possible thromboembolic complications in this patient population.
