Sirolimus-eluting stents (SESs) recently proved to be superior to bare metal stents (BMSs) in decreasing the need for repeat revascularization in patients with ST-segment elevation myocardial infarction (STEMI) at 1 year. Whether this also holds for paclitaxel-eluting stents (PESs) is currently unclear and the long-term relatively efficacy of the 2 drug-eluting stents is currently unknown. We investigated the 3-year efficacy of SESs and PESs versus BMSs in patients with STEMI. Primary angioplasty was performed in a consecutive group of 505 patients (BMSs in 183, SESs in 186, PESs in 136). At 3 years, the cumulative mortality rate was comparable in the 3 groups: 13.3% in the BMS group, 11.5% in the SES group, and 12.4% in the PES group (nonsignificant for all). The rate of target vessel revascularization (TVR) was 12.0% in the BMS group compared with 8.0% and 7.7% in the SES and PES groups, respectively (p = 0.12 for BMS vs SES, 0.30 for BMS vs PES, 0.62 for SES vs PES). The cumulative incidence of death, MI, or TVR was 25.5% in the BMS group compared with 17.9% and 20.6% in the SES and PES groups, respectively (p = 0.06 for BMS vs SES, 0.32 for BMS vs PES, 0.45 for SES vs PES). Angiographic stent thrombosis occurred in 2.4% of all patients (BMS 1.6%, SES 2.7%, PES 2.9%). In conclusion, in this relatively small consecutive patient cohort, the use of SESs and PESs was no longer associated with significantly lower rates of TVR and major adverse cardiace events in patients with STEMI after 3 years of follow-up. A high frequency of stent thrombosis was observed in the 2 drug-eluting stent groups. [Copyright &y& Elsevier]

REPERFUSION , *BLOOD platelets , *GLYCOPROTEINS , *MYOCARDIAL infarction - Abstract
There is continued debate as to whether a combined reperfusion regimen with platelet glycoprotein IIb/IIIa inhibitors provides additional benefit in optimal myocardial reperfusion of patients with a ST-elevation acute myocardial infarction (AMI). In addition, the best angiographic method to evaluate optimal myocardial reperfusion is still controversial. Patients (n = 144) with a first AMI presenting <6 hours from onset of symptoms were randomized to receive a conjunctive strategy (n = 72) with low-dose alteplase (50 mg) and tirofiban (4 μg/kg/min/30 minute bolus; infusion of 0.1 μg/kg/minute), or tirofiban plus stenting percutaneous coronary intervention (PCI). Control patients (n = 72) received standard strategy with either full-dose alteplase (100 mg) or stenting PCI. All patients were submitted to coronary angiographic study at 90 minutes. The primary end point was Thrombolysis In Myocardial Infarction (TIMI) grade 3 flow at 90 minutes. Secondary end points were TIMI myocardial perfusion (TMP) rates, a composite end point at 30 days (death, reinfarction, refractory ischemia, stroke, heart failure, revascularization procedures, or pulmonary edema), and bleeding or hematologic variables. The rate of TIMI 3 flow at 90 minutes for patients treated with alteplase alone was 42% compared with 64% for those who received low-dose alteplase and tirofiban. Standard stenting PCI achieved 81% of TIMI 3 flow compared with 92% when tirofiban was used. Significantly higher rates of TMP grade 3 were observed when tirofiban was used as the adjunctive treatment in both alteplase (66% vs 47%) and stenting PCI (73% vs 55%). Higher rates of the composite end point were observed in standard regimens compared with conjunctive regimens (hazard ratio 5.8, 95% confidence interval 1.27 to 26.6, p = 0.023). Regardless of reperfusion regimen, better outcomes were observed when a combination of TIMI 3 flow and TMP grade 3 was achieved. Beyond TIMI 3 flow rate, the TMP grade was an important determinant. The rates of major bleeding were similar (2.8%) for standard versus conjunctive regimens with tirofiban. Thus, tirofiban as a conjunctive therapy for lytic and stenting regimens not only improves TIMI 3 flow rates, but also the TMP3 rates, which are related to a better clinical outcome without an increase in the risk of major bleeding. This study supports the hypothesis that platelets play a key role not only in the atherothrombosis process, but also in the disturbances of microcirculation and tissue perfusion.

- Abstract
`To analyze the impact of additional coronary artery disease, quantified by the SYNTAX (SYNergy between PCI with TAXus and cardiac surgery) score, on left ventricular ejection fraction (LVEF) and long-term outcomes in a cohort of ST-elevated myocardial infarction (STEMI) patients with a concomitant chronic total coronary occlusion (CTO). A total of 302 STEMI patients were randomized to percutaneous coronary intervention of a CTO (CTO PCI) (n = 148) or conservative CTO treatment (n = 154). SYNTAX scores were calculated by an independent corelab (Cardialysis BV, Rotterdam) at two time-points: (1) at baseline, and (2) after primary PCI in the conservative CTO arm and after CTO PCI in the invasive arm (named 'discharge SYNTAX score'). The population was divided in two groups (below or equal to the median SYNTAX score preprimary PCI, or above the median). At 4-month follow-up, the LVEF was significantly lower in patients in the group with a SYNTAX score above the group median (42.8% vs 48.5%, p = 0.001), and the SYNTAX score was an independent predictor for LVEF at 4 months (β-0.151 (SE 0.068), p = 0.028). In the group with a SYNTAX score above the group median the mortality rate was higher (10.1% vs 3.9%, p = 0.025), and there was a trend towards a higher MACE rate (15.4% vs 8.5%, p = 0.063). In conclusion, in this sub-analysis of the EXPLORE trial we observed a worse LVEF and a higher mortality rate for patients with a SYNTAX score above the median. We found that the SYNTAX score is an independent negative predictor for LVEF and an independent positive predictor for LVEDV at 4-month follow-up., (Copyright © 2019 The Authors.
