Clinical Outcome of First- vs Second-Generation DES According to DAPT Duration: Results of ARCTIC-Generation.

ABSTRACT: There is an apparent benefit with extension of dual antiplatelet therapy (DAPT) beyond 1 year after implantation of drug-eluting stents (DES). Assessment by a Double Randomization of a Conventional Antiplatelet Strategy vs a Monitoring-Guided Strategy for Drug-Eluting Stent Implantation, and of Treatment Interruption vs Continuation One Year After Stenting (ARCTIC)-Generation assessed whether there is a difference of outcome between first- vs second-generation DES and if there is an interaction with DAPT duration in the ARCTIC-Interruption study. ARCTIC-Interruption randomly allocated 1259 patients 1 year after stent implantation to a strategy of interruption of DAPT (n = 624), in which aspirin antiplatelet treatment only was maintained, or DAPT continuation (n = 635) for 6 to 18 additional months. The primary endpoint was the composite of death, myocardial infarction, stent thrombosis, stroke, or urgent revascularization. A total of 520 and 722 patients received a first- and a second-generation DES, respectively. After a median follow-up of 17 months (interquartile range, 15-18 months) after randomization, the primary endpoint occurred in 32 (6.2%) and 19 (2.6%) patients with first- and second-generation DES, respectively (hazard ratio: 2.31, 95% confidence interval: 1.31-4.07, P = 0.004). This was observed irrespective of the strategy of interruption or continuation of DAPT and timing of study recruitment. Major bleeding events occurred in 4 (0.8%) and 3 patients (0.4%) with first- and second-generation DES, respectively (hazard ratio: 1.79, 95% confidence interval: 0.40-8.02, P = 0.44). Results did not change after multiple adjustments for potential confounding variables. ARCTIC-Generation showed worse clinical outcome with first- vs second-generation DES, a difference that appeared to persist even with prolonged DAPT.

Project description:BackgroundThere is a paucity of data regarding the long-term clinical outcomes of first- versus second-generation drug-eluting stent (DES), especially when used to treat complex lesions such as bifurcation lesions.ObjectivesThe current study compares the efficacy and safety of first- versus second-generation DES at the 5-year follow-up in patients who underwent bifurcation percutaneous coronary intervention (PCI).MethodsA total of 5,498 patients with a bifurcation lesion who underwent PCI were pooled at a single patient level from COBIS (Coronary Bifurcation Stenting) registries II and III. Five-year target lesion failure (TLF) (the composite of cardiac death, myocardial infarction [MI], and target lesion revascularization [TLR]) and cardiac death or MI were compared between the use of first-generation DES (n = 2,436) and second-generation DES (n = 3,062) during PCI. Propensity score matching was performed to reduce selection bias.ResultsAfter a 1:1 propensity score matching procedure was conducted, the cohort consisted of 1,702 matched pairs. Patients treated with second-generation DES had a significantly lower risk of TLF at 5 years than those treated with first-generation DES in both overall and propensity-matched populations (matched hazard ratio [HRmatched]: 0.576; 95% confidence interval [CI]: 0.456 to 0.727; p <0.001). There were no significant differences in risk of a composite of cardiac death or MI between the 2 groups (HRmatched: 0.782; 95% CI: 0.539 to 1.133, P = 0.193). However, among patients who required a 2-stent technique, use of the second-generation DES reduced cardiac death or MI (HRmatched:0.422; 95% CI: 0.209 to 0.851, P = 0.016). On the other hand, among patients who required a one-stent technique, the risk of a composite of cardiac death or MI was similar between the 2 groups (HRmatched: 1.046; 95% CI: 0.664 to 1.650, P = 0.845). There was a significant interaction between stent generation and treatment strategy for cardiac death or MI (interaction P = 0.029).ConclusionsIn patients treated with PCI for a bifurcation lesion, the use of second-generation DES was associated with a significantly reduced risk of 5-year TLF than the use of first-generation DES.

Project description:Because early treatment choice is critical in first-episode schizophrenia-spectrum disorders (FES), this meta-analysis compared efficacy and tolerability of individual second-generation antipsychotics (SGAs) with first-generation antipsychotics (FGAs) in FES. We conducted systematic literature search (until 12 December 2010) and meta-analysis of acute, randomized trials with ?1 FGA vs. SGA comparison; patients in their first episode of psychosis and diagnosed with schizophrenia-spectrum disorders; available data for psychopathology change, treatment response, treatment discontinuation, adverse effects, or cognition. Across 13 trials (n = 2509), olanzapine (seven trials) and amisulpride (one trial) outperformed FGAs (haloperidol: 9/13 trials) in 9/13 and 8/13 efficacy outcomes, respectively, risperidone (eight trials) in 4/13, quetiapine (one trial) in 3/13 and clozapine (two trials) and ziprasidone (one trial) in 1/13, each. Compared to FGAs, extrapyramidal symptom (EPS)-related outcomes were less frequent with olanzapine, risperidone and clozapine, but weight gain was greater with clozapine, olanzapine and risperidone. Pooled SGAs were similar to FGAs regarding total psychopathology change, depression, treatment response and metabolic changes. SGAs significantly outperformed FGAs regarding lower treatment discontinuation, irrespective of cause, negative symptoms, global cognition and less EPS and akathisia, while SGAs increased weight more (p < 0.05-0.01). Results were not affected by FGA dose or publication bias, but industry-sponsored studies favoured SGAs more than federally funded studies. To summarize, in FES, olanzapine, amisulpride and, less so, risperidone and quetiapine showed superior efficacy, greater treatment persistence and less EPS than FGAs. However, weight increase with olanzapine, risperidone and clozapine and metabolic changes with olanzapine were greater. Additional FES studies including broader-based SGAs and FGAs are needed.
