    The introduction of the SYNTAX (Synergy Between PCI With Taxus and Cardiac Surgery) score has prompted a renewed interest for angiographic risk stratification in patients undergoing percutaneous coronary intervention. Syntax score is based on qualitative and quantitative characterization of coronary artery disease by including 11 angiographic variables that take into consideration lesion location and characteristics. Thus far, this score has been shown to be an effective tool to risk-stratify patients with complex coronary artery disease undergoing percutaneous coronary intervention in the landmark SYNTAX trial, as well as in other clinical settings. This review provides an overview of its current applications, including its integration with other nonangiographic clinical scores, and explores future applications of the SYNTAX and derived scores.

    Objectives the purpose of this study was to quantify the extent and complexity of residual coronary stenoses following percutaneous coronary intervention (PCI) and to evaluate its impact on adverse ischemic outcomes.Background Incomplete revascularization (IR) after PCI is common, and most studies have suggested that IR is associated with a worse prognosis compared with complete revascularization (CR). However, formal quantification of the extent and complexity of residual atherosclerosis after PCI has not been performed.Methods the baseline Synergy Between PCI With Taxus and Cardiac Surgery (SYNTAX) score (bSS) from 2,686 angiograms from patients with moderate-and high-risk acute coronary syndrome (ACS) undergoing PCI enrolled in the prospective ACUITY (Acute Catheterization and Urgent Intervention Triage Strategy) trial was determined. the SS after PCI was also assessed, generating the residual SS (rSS). Patients with rSS >0 were defined as having IR and were stratified by rSS tertiles, and their outcomes were compared to the CR group.Results the bSS was 12.8 +/- 6.7, and after PCI the rSS was 5.6 +/- 2.2. Following PCI, 1,084 patients (40.4%) had rSS = 0 (CR), 523 (19.5%) had rSS >0 but 2 but 8. Age, insulin-treated diabetes, hypertension, smoking, elevated biomarkers or ST-segment deviation, and lower ejection fraction were more frequent in patients with IR compared with CR. the 30-day and 1-year rates of ischemic events were significantly higher in the IR group compared with the CR group, especially those with high rSS. By multivariable analysis, rSS was a strong independent predictor of all ischemic outcomes at 1 year, including all-cause mortality (hazard ratio: 1.05, 95% confidence interval: 1.02 to 1.09, p = 0.006).Conclusions the rSS is useful to quantify and risk-stratify the degree and complexity of residual stenosis after PCI. Specifically, rSS >8.0 after PCI in patients with moderate-and high-risk ACS is associated with a poor 30-day and 1-year prognosis.

    Get PDF
    Aims: The aim of this study was to evaluate 30-day safety and efficacy outcomes of transcatheter aortic valve implantation (TAVI) performed with the SAPIEN 3 Ultra system. Methods and results: The S3U registry is a physician-led, post-approval, multicentre, observational registry of transfemoral TAVI with the SAPIEN 3 Ultra. New features include an improved sealing skirt, a 14 Fr expandable sheath and a new delivery catheter. Overall, 139 consecutive patients at nine participating centres were enrolled. Mean age was 81.4 +/- 8.3 years, average STS score 3.8 +/- 2.4%. The vast majority (97.2%) underwent TAVI with local anaesthesia (28.8%) or conscious sedation (68.3%). Balloon predilatation was performed in 30 patients (21.6%), post-dilatation in three (2.2%). In-hospital, there were no cases of death, stroke, or conversion to open heart surgery. Major vascular complications occurred in three patients (2.2%), as well as major or life-threatening bleedings in three patients (2.2%). There were two moderate (1.4%) and no moderate/severe paravalvular leaks. Median length of stay after TAVI was three days (IQR 3-5 days). At 30 days, there were no deaths, MI, or strokes, and the incidence of new permanent pacemaker implantation was 4.4%. Conclusions: This first multicentre international experience of transfemoral TAVI with the SAPIEN 3 Ultra transcatheter heart valve shows good in-hospital and 30-day clinical outcomes.Peer reviewe

    Long-term safety of drug-eluting and bare-metal stents: Evidence from a comprehensive network meta-analysis

    Abstract Background Previous meta-analyses have investigated the relative safety and efficacy profiles of different types of drug-eluting stents (DES) and bare-metal stents (BMS); however, most prior trials in these meta-analyses reported follow-up to only 1 year, and as such, the relative long-term safety and efficacy of these devices are unknown. Many recent studies have now reported extended follow-up data. Objectives This study sought to investigate the long-term safety and efficacy of durable polymer-based DES, bioabsorbable polymer-based biolimus-eluting stents (BES), and BMS by means of network meta-analysis. Methods Randomized controlled trials comparing DES to each other or to BMS were searched through MEDLINE, EMBASE, and Cochrane databases and proceedings of international meetings. Information on study design, inclusion and exclusion criteria, sample characteristics, and clinical outcomes was extracted. Results Fifty-one trials that included a total of 52,158 randomized patients with follow-up duration ≥3 years were analyzed. At a median follow-up of 3.8 years, cobalt-chromium everolimus-eluting stents (EES) were associated with lower rates of mortality, definite stent thrombosis (ST), and myocardial infarction than BMS, paclitaxel-eluting stents (PES), and sirolimus-eluting stents (SES) and less ST than BES. Phosphorylcholine-based zotarolimus-eluting stents had lower rates of definite ST than SES and lower rates of myocardial infarction than BMS and PES. The late rates of target-vessel revascularization were reduced with all DES compared with BMS, with cobalt-chromium EES, platinum chromium-EES, SES, and BES also having lower target-vessel revascularization rates than PES. Conclusions After a median follow-up of 3.8 years, all DES demonstrated superior efficacy compared with BMS. Among DES, second-generation devices have substantially improved long-term safety and efficacy outcomes compared with first-generation device

    Background Randomized controlled trials comparing short- (≤6 months) with long-term (≥1 year) dual antiplatelet therapy (DAPT) after drug-eluting stent(s) (DES) placement have been insufficiently powered to detect significant differences in the risk of major adverse cardiac events (MACE). Objectives This study sought to compare clinical outcomes between short- (≤6 months) and long-term (1 year) DAPT and among 3 months, 6 months, and 1 year of DAPT post-DES placement by performing an individual patient data pairwise and network meta-analysis. Methods Randomized controlled trials comparing DAPT durations after DES placement were searched through the MEDLINE, EMBASE, and Cochrane databases and in international meeting proceedings. The primary study outcome was 1-year risk of MACE (cardiac death, myocardial infarction, or definite/probable stent thrombosis). Results Four trials including 8,180 randomized patients were identified. At 1-year follow-up, short-term DAPT was associated with similar rates of MACE (hazard ratio [HR]: 1.11; 95% confidence interval [CI]: 0.86 to 1.43; p = 0.44), but significantly lower rates of bleeding (HR: 0.66; 95% CI: 0.46 to 0.94; p = 0.03) versus prolonged DAPT. Comparable results were apparent in the landmark period between DAPT discontinuation and 1-year follow-up (for MACE: HR: 1.20; 95% CI: 0.77 to 1.89; p = 0.42) (for bleeding: HR: 0.44; 95% CI: 0.21 to 0.91; p = 0.03). There were no significant differences in 1-year rates of MACE among 3-month versus 1-year DAPT, 6-month versus 1-year DAPT, or 3-month versus 6-month DAPT. Conclusions Compared with prolonged DAPT, short-term DAPT is associated with similar rates of MACE but lower rates of bleeding after DES placement

      Background: Accuracy of high sensitive troponin (hs-cTn) to detect coronary artery disease (CAD) in patients with renal insufficiency is not established. The aim of this study was to evaluate the prognostic role of hs-cTn T and I in patients with chronic kidney disease (CKD). Methods: All consecutive patients with chest pain, renal insufficiency (eGFR < 60 mL/min/1.73 m2) and high sensitive troponin level were included. The predictive value of baseline and interval troponin (hs-cTnT and hs-cTnI) for the presence of CAD was assessed. Results: One hundred and thirteen patients with troponin I and 534 with troponin T were included, with 95 (84%) and 463 (87%) diagnosis of CAD respectively. There were no differences in clinical, procedural and outcomes between the two assays. For both, baseline hs-cTn values did not differ be­tween patients with/without CAD showing low area under the curve (AUC). For interval levels, hs-cTnI was significantly higher for patients with CAD (0.2 ± 0.8 vs. 8.9 ± 4.6 ng/mL; p = 0.04) and AUC was more accurate for troponin I than hs-cTnT (AUC 0.85 vs. 0.69). Peak level was greater for hs-cTnI in patients with CAD or thrombus (0.4 ± 0.6 vs. 15 ± 20 ng/mL; p = 0.02; AUC 0.87: 0.79–0.93); no differences were found for troponin T assays (0.8 ± 1.5 vs. 2.2 ± 3.6 ng/mL; p = 1.7), with lower AUC (0.73: 0.69–0.77). Peak troponin levels (both T and I) independently predicted all cause death at 30 days. Conclusions: Patients with CKD presenting with altered troponin are at high risk of coronary disease. Peak level of both troponin assays predicts events at 30 days, with troponin I being more accurate than troponin T. (Cardiol J 2017; 24, 2: 139–150
