rome and ST-Elevation-Myocardial-Infarction

On March 9, 2020, the Italian government imposed a national lockdown to tackle the COronaVIrus Disease 19 (COVID-19) pandemic, including stay at home recommendations. The precise impact of COVID-19 scare and lockdown on emergency access for acute myocardial infarction (MI) is still subject to debate.. Data on all patients undergoing invasive coronary angiography at 9 hospitals in the greater area of Rome, Italy, between February 19, 2020 and March 29, 2020 were retrospectively collected. Incidence of ST-elevation MI (STEMI), and non-ST-elevation MI (NSTEMI), as well as corresponding percutaneous coronary intervention (PCI), was compared distinguishing two different 20-day time periods (before vs. on or after March 10, 2020).. During the study period, 1068 patients underwent coronary angiography, 142 (13%) with STEMI and 169 (16%) with NSTEMI. The average daily number of STEMI decreased from 4.3 before the lockdown to 2.9 after the lockdown (P=0.021). Similarly, the average daily number of NSTEMI changed from 5.0 to 3.5 (P=0.028). The average daily number of primary PCI changed from 4.2 to 2.9 (P=0.030), while the average daily number of PCI for NSTEMI changed from 3.5 to 2.5 (P=0.087). For STEMI patients, the time from symptom onset to hospital arrival (onset-to-door time less than three hours) showed a significant increase after the lockdown (P=0.018), whereas door-to-balloon time did not change significantly from before to after the lockdown (P=0.609).. The present study, originally reporting on the trends in STEMI and NSTEMI in the Rome area, highlights that significant decreases in the incidence of both acute coronary syndromes occurred between February 19, 2020 and March 29, 2020, together with increases in time from symptom onset to hospital arrival, luckily without changes in door-to-balloon time.

This study aimed at assessing the performance of a new generation polymer-free biolimus-eluting stent (BES) in real-world patients with ST-segment elevation myocardial infarction (STEMI).. Polymers components of early-generation drug-eluting stents have been implicated in the pathogenesis of delayed arterial healing, vessel remodeling, and delayed stent thrombosis. Recently, a novel polymer-free BES has shown excellent clinical performance in clinical trial setting.. Overall, 175 consecutive patients (64 ± 14 years, 141 men) treated with the BioFreedom (Biosensors Europe, Morges, Switzerland) polymer-free BES because of STEMI were included in this study. The primary endpoint was the rate of major adverse cardiac events (MACE), a composite of cardiac death, recurrent myocardial infarction, and ischemia-driven target vessel revascularization at 1 year follow-up. A subgroup of patients underwent 6-month angiographic follow-up. Dual antiplatelet therapy was prescribed for 12 months after STEMI.. At 1 year, the cumulative rate of MACE was 4.6%. One patient (0.6%) had an arrhythmic cardiac death and five (2.9%) had ischemia-driven target vessel revascularization, although only three (1.7%) had target lesion revascularization. Two (1.1%) patients had acute stent thrombosis yielding nonfatal myocardial infarction. In 70 patients (63 ± 14 years, 61 men), quantitative coronary angiography at 6-month follow-up revealed diameter stenosis of 24.1 ± 13.7% and minimal lumen diameter of 2.29 ± 0.56 mm, yielding a late lumen loss of 0.13 ± 0.14 mm.. In real-world setting, implantation of a new-generation polymer-free BES during STEMI is associated with favorable clinical and angiographic results, pointing toward the overall efficacy and safety of the device in complex clinical scenarios.
