- AIMS: The aim of this study was to identify predictors of complete ST-segment resolution (STR) pre-primary percutaneous coronary intervention (PCI) in patients enrolled in the ATLANTIC trial.METHODS AND RESULTS: ECGs recorded at the time of inclusion (pre-hospital [pre-H]-ECG) and in the catheterisation laboratory before angiography (pre-PCI-ECG) were analysed by an independent core laboratory. Complete STR was defined as ≥70%. Complete STR occurred pre-PCI in 12.8% (204/1,598) of patients and predicted lower 30-day composite MACCE (OR=0.10, 95% CI: 0.002-0.57, p=0.001) and total mortality (OR=0.16, 95% CI: 0.004-0.95, p=0.035). Independent predictors of complete STR included the time from index event to pre-H-ECG (OR=0.94, 95% CI: 0.89-1.00, p=0.035), use of heparins before pre-PCI-ECG (OR=1.75, 95% CI: 1.25-2.45, p=0.001) and time from pre-H-ECG to pre-PCI-ECG (OR=1.09, 95% CI: 1.03-1.16, p=0.005). In the pre-H ticagrelor group, patients with complete STR had a significantly longer delay between pre-H-ECG and pre-PCI-ECG compared to patients without complete STR (median 53 [44-73] vs. 49 [38.5-61] mins, p=0.001); however, this was not observed in the control group (in-hospital ticagrelor) (50 [40-67] vs. 49 [39-61] mins, p=0.258).CONCLUSIONS: Short patient delay, early administration of anticoagulant and ticagrelor if a long transfer delay is expected may help to achieve reperfusion prior to PCI. Pre-H treatment may be beneficial in patients with longer transfer delays, allowing the drug to become biologically active.

- It is known that myocardial ischaemia and infarction leads to severe metabolic and electrophysiological changes that induce silent or symptomatic life-threatening arrhythmias. Sudden cardiac death is most often attributed to this pathophysiology, but many patients survive the early stage of an acute coronary syndrome (ACS) reaching a medical facility where the management of ischaemia and infarction must include continuous electrocardiographic (ECG) and hemodynamic monitoring, and a prompt therapeutic response to incident sustained arrhythmias. During the last decade, the hospital locations in which arrhythmias are most relevant have changed to include the cardiac catheterization laboratory, since the preferred management of early acute ACS is generally interventional in nature. However, a large proportion of patients are still managed medically.Both atrial and ventricular arrhythmias may occur in the setting of ACS and sustained ventricular tachyarrhythmias (VAs) may be associated with circulatory collapse and require immediate treatment. Atrial fibrillation (AF) may also warrant urgent treatment when a fast ventricular rate is associated with hemodynamic deterioration. The management of other arrhythmias is also based largely on symptoms rather than to avert progression to more serious arrhythmias. Prophylactic antiarrhythmic management strategies have largely been discouraged.Although the mainstay of antiarrhythmic therapy used to rely on antiarrhythmic drugs (AADs), particularly sodium channel blockers and amiodarone, their use has now declined, since clinical evidence to support such treatment has never been convincing. Therapy for acute coronary syndrome and arrhythmia management are now based increasingly on invasive approaches. The changes in the clinical approach to arrhythmia management in ACS have been so substantial that the European Heart Rhythm Association, the Acute Cardiovascular Care Association and the European Association of Percutaneous Cardiovascular Interventions established a task force to define the current position.

- AIMS: To investigate the safety and efficacy of dabigatran dual therapy (110 or 150 mg twice daily, plus clopidogrel or ticagrelor) vs warfarin triple therapy in patients with atrial fibrillation undergoing PCI for ST elevation myocardial infarction (STEMI).METHODS AND RESULTS: In RE-DUAL PCI, 305 patients with STEMI were randomised to dabigatran 110 mg (n=113 versus 106 warfarin) or 150 mg (n=86 versus 84 warfarin). Primary endpoint was time to first major or clinically relevant non-major bleeding event (MBE/CRNMBE). The thrombotic endpoint was a composite of death, thromboembolic events, or unplanned revascularisation. In STEMI patients, dabigatran 110 mg (HR 0.39, 95% CI 0.20-0.74) and 150 mg (0.43, 0.21-0.89) dual therapy reduced the risk of MBE/CRNMBE versus warfarin triple therapy (p interaction vs all other patients = 0.31 and 0.16). Risk of thrombotic events, for dabigatran 110 mg (HR 1.61, 95% CI: 0.85-3.08) and 150 mg (0.56, 0.20-1.51) had p interactions of 0.20 and 0.33, respectively. For net clinical benefit, HRs were 0.74 (95% CI 0.46-1.17) and 0.49 (0.27-0.91) for dabigatran 110 and 150 mg (p interaction = 0.80 and 0.12).CONCLUSIONS: In patients after PCI for STEMI, dabigatran dual therapy had lower risks of bleeding events versus warfarin triple therapy with similar risks of thromboembolic events, supporting the use of dabigatran dual therapy even in patients with high thrombotic risk.
