Abstract
Abstract
Aims
To compare the safety and efficacy of antithrombotic regimens following transcatheter aortic valve replacement (TAVR) in patients without having an indication for chronic oral anticoagulation
Methods and results
We conducted a Prospero-registered systematic review and network meta-analysis of randomized controlled trials evaluating post-TAVR antithrombotic regimens up to March 2021. We estimated the relative risk and 95% confidence intervals using a fixed effect model in a frequentist pairwise and network metanalytic approach. We included 6 studies comprising of 3,777 patients with a mean weighted follow-up of 13.3 months. Single antiplatelet therapy (SAPT) was associated with a significant reduction of life-threatening, disabling, or major bleeding compared to dual antiplatelet therapy (DAPT) (Risk Ratio [RR] 0.44, 95% confidence interval [CI]: 0.28–0.69), apixaban (RR: 0.47, 95% CI 0.26–0.84) and low-dose rivaroxaban + 3-month SAPT (RR: 0.30, 95% CI: 0.16–0.57). Risk of all-cause death was significantly reduced with DAPT compared to low-dose rivaroxaban + 3-month SAPT (RR: 0.60, 95% CI: 0.41–0.88) and a consistent reduction was observed with SAPT and DAPT compared to apixaban (RR: 0.60, 95% CI: 0.31–1.16 and RR: 0.58, 95% CI: 0.32–1.04, respectively). There were no differences between the various regimens with respect to myocardial infarction and stroke. Apixaban significantly reduced the risk of pulmonary embolism, valve thrombosis and grade 3 or 4 reduced leaflet motion.
Conclusion
Following TAVR in patients without an indication for chronic oral anticoagulant, SAPT was associated with the lowest risk of bleeding compared to DAPT and direct oral anticoagulant-based regimens without significant ischemic offset.

Abstract
Abstract
Background
Left Ventricular Thrombus (LVT) is associated with a high risk of thromboembolic complications such as stroke. Contemporary data are lacking on the management, prognosis and treatment of LVT, particularly with the emergence of the non-vitamin K antagonist anticoagulants (NOACs).
Purpose
To study the time and predictive factors associated with thrombus regression on treatment and its association with survival, embolic and bleeding complications.
Methods
From January 2011 to January 2018, a computerized case sensitive search of LVT was performed on 90 065 consecutive echocardiogram reports. All patients with a confirmed LVT were included in this analysis after imaging review by two independent experts. Repeated echocardiographic data, treatment management and clinical outcomes were collected during follow-up. Major adverse cardiac events (MACE), defined as the composite of death, ischemic stroke or transient ischemic attack (TIA), myocardial infarction (MI) or embolic peripheral artery occlusion were analyzed as well as major bleeding events (BARC ≥3) and the predictive factors and impact of LVT regression.
Results
We identified 174 patients with a suspected LVT of whom 159 had confirmed LVT on two different cardiac imaging exams. Ischemic cardiomyopathy was the main cause of LVT (n=125, 78.6%) including 56 (35.2%) patients with an acute ST segment elevation MI. The mean left ventricular ejection fraction was 31.9±12.5% with predominant (98.1%) apical location of the LVT.
Anticoagulation therapy was achieved with vitamin K antagonists, NOACs and parenteral heparins in 48.7%, 22.8% and 27.8% of patients, respectively. Concomitant antiplatelet therapy was prescribed in 67.9% of patients. Total LVT regression was reached in two third of patients (62.3%, n=99) within a median time of 103 [32–392] days. Independent predictors of total LVT regression were an ischemic cardiomyopathy (HR: 0.36 [0.19–0.70], p=0.002), a larger baseline thrombus area (HR=0.66 [0.45–0.96], p<0.031) and a prolonged anticoagulation therapy over 3 months (HR=0.11 [0.05–0.22], p<0.0001).
During a median follow-up of 632 [187–1126] days, MACE occurred in 59 (37.1%) patients with a 18.9% rate of mortality and 13.2% of major bleeding. Patients with a total LVT regression had a non-significant lower rate of MACE as compared with patients without total LVT regression (35.4% vs. 40.0%; HR=0.71 [0.42–1.21]; p=0.20), and a significant lower rate of mortality (15.2% vs. 25.0%; HR=0.48 [0.23–0.98]; p=0.039).
Occurence of mortality (A) and MACE (B)
Conclusions
The prognosis of LVT remains severe with a high risk of major cardiovascular event and mortality. Total LVT regression, mostly reached in 3 months, can be obtained with both vitamin K antagonists and NOACs and is associated with a better prognosis.

Abstract
BACKGROUND Atorvastatin, a new enantiomerically pure synthetic statin, has shown a marked low-density lipoprotein (LDL) cholesterol reduction at doses ranging from 10 to 80 mg/d. This trial was designed to compare the efficacy of atorvastatin 10 mg with simvastatin 10 mg and 20 mg, the latter dose being commonly used in some countries. METHODS AND RESULTS A parallel group, randomized, PROBE, multicenter study was conducted to compare the efficacy of 10 mg/d atorvastatin with that of 10 mg/d simvastatin and 20 mg/d simvastatin in patients with primary hypercholesterolemia. After a 6-week diet-placebo lead-in period, 272 patients with LDL cholesterol > or = 160 mg/dL and triglycerides < or = 300 mg/dL were randomized to 6 weeks of treatment with atorvastatin 10 mg (109 patients), simvastatin 20 mg (109 patients), or simvastatin 10 mg (54 patients). In the main analysis, which tested the equivalence of atorvastatin 10 mg and simvastatin 20 mg, the mean percent change in LDL cholesterol for atorvastatin 10 mg (-37.0%) was greater than and not equivalent to simvastatin 20 mg (-33.8%). In the secondary analysis, which compared the efficacy of atorvastatin 10 mg with that of simvastatin 10 mg, the mean decrease in LDL cholesterol was significantly greater (P < .001) for atorvastatin 10 mg than for simvastatin 10 mg (-37.0% vs. -28.9%). The two drugs were well tolerated, with an incidence of clinical and biochemical side effects similar among the 3 treatment groups. CONCLUSION In primary hypercholesterolemia, atorvastatin 10 mg was more effective and nonequivalent to simvastatin 20 mg and significantly more effective than simvastatin 10 mg for reducing LDL cholesterol levels.

Abstract
The objectives were to evaluate gabapentin add-on therapy in a large population under conditions close to real practice and to determine the therapeutic doses as reached with adaptable dosages. A 6-month multicentre, open-label study, involved addition of gabapentin to pre-existing treatment at the initial dosage of 1200 mg and subsequent adjustment between 900 and 2400 mg/day according to efficacy and tolerability. A study group of 610 adult patients, with partial epilepsy, persistent seizures and a median seizure frequency with a baseline of 7.2 per month were recruited; one-third had less than four seizures per month. Polypharmacy was frequent, with a mean of 2.3 concomitant drugs. After 6 months, 368 patients (62%) continued on gabapentin, at a mean dosage of 1739 mg/day with 44% of responders. On an intention-to-treat basis, median reduction in frequency was 21.2%, and the responder rate was 33.9%. The responder rate increased to 40.7% in the less severe subgroup receiving only one concomitant drug. Seventy-nine patients (13.4%) remained without seizures during the last evaluation period, versus nine (1.5%) during the baseline. Most of them had initially less than four seizures per month. The most frequent adverse effects, somnolence (29.3%), asthenia (14.6%), nausea (7.9%), ataxia (7.7%) and vertigo (7.2%), occurred rapidly after initial titration to 1200 mg/day, and were usually transitory. Weight gain (8.8%) seemed to be related to gabapentin dose. The combination of two recent drugs, vigabatrin and gabapentin, in 190 patients led to similar efficacy levels, with a tendency for more frequent somnolence and asthenia.
