BACKGROUND: Given the ongoing burden of cardiovascular disease and an ageing population, physical activity in patients with coronary artery disease needs to be emphasized. This study assessed whether sedentary behaviour and physical activity levels differed among older patients (≥75 years) following percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS) consisting of ST-segment elevation myocardial infarction (STEMI) and non STEMI (NSTEMI) versus an elective admission control group of stable angina patients...

OBJECTIVES: Previous studies have shown that smokers presented with ST-segment elevation myocardial infarction (STEMI) a decade earlier than non-smokers. However, no account has been made for population smoking trends, an important deficit addressed by this study. METHODS: The combination of admission data on patients with acute STEMI undergoing percutaneous coronary intervention and demographic data supplied by the Office for National Statistics for the South Yorkshire population between 2009-2012 were analysed to generate incidence rates and rate ratios (RR) to quantify the relative risk of STEMI from smoking, overall and by age group...

OBJECTIVES: To determine the causes of software misinterpretation of ST elevation myocardial infarction (STEMI) compared to clinically identified STEMI to identify opportunities to improve prehospital STEMI identification. METHODS: We compared ECGs acquired from July 2011 through June 2012 using the LIFEPAK 15 on adult patients transported by the Los Angeles Fire Department. Cases included patients ≥18 years who received a prehospital ECG. Software interpretation of the ECG (STEMI or not) was compared with data in the regional EMS registry to classify the interpretation as true positive (TP), true negative (TN), false positive (FP), or false negative (FN)...

BACKGROUND: Massive intracoronary thrombus is associated with adverse procedural results including failed aspiration and unfavourable reperfusion. We aim to evaluate the effect of the intracoronary administration of antithrombotic agents via a perfusion catheter in patients with ST-segment elevation myocardial infarction (STEMI) presenting with a large thrombus burden and failed aspiration. METHODS: We retrospectively analyzed the thrombus burden, the TIMI grade flow, and the myocardial Blush in 25 consecutive STEMI patients with a large thrombus burden and failed manual aspiration, who received intracoronary infusion of glycoprotein IIb/IIIa inhibitors (N=17) or bivalirudine (N=8) via a 6F-infusion catheter (ClearWay™ RX) RESULTS: Mean age was 67±14 years, 16 patients (64 %) presented with anterior STEMI, and 7 (28 %) with cardiogenic shock...

BACKGROUND: Patients with ST-segment elevation myocardial infarction (STEMI) undergoing drug-eluting stent (DES) implantation are at increased risk of late adverse events, partly explained by an exaggerated inflammatory reaction to durable-polymer stent coatings. OBJECTIVES: We sought to investigate whether implantation of polymer-free DES would reduce this risk. METHODS: In the ISAR-TEST 5 (the Intracoronary Stenting and Angiographic Results: Test Efficacy of Sirolimus- and Probucol- and Zotarolimus-Eluting Stents) trial, patients were randomly allocated to receive a polymer-free sirolimus- and probucol-eluting stent or a new generation durable-polymer zotarolimus-eluting stent...

OBJECTIVES: This observational study assessed the 9-month clinical outcomes in patients with coronary bifurcation lesions suitable for drug-coated balloon (DCB) angioplasty. It was the intention to use DCB's without additional stenting (DCB-only strategy) in selected patients for this chosen strategy. Bail-out main branch (MB) and/or side branch (SB) stenting, however, were permissible when flow limiting dissections or excessive recoil occurred. BACKGROUND: A multitude of interventional strategies have been studied to treat bifurcation lesions...
