Pre-hospital heparin is not associated with infarct vessel patency and mortality in ST-segment elevation myocardial infarction patients with out-of-hospital cardiac arrest.

Background: Pre-hospital heparin administration has been reported to improve prognosis in patients with out-of-hospital cardiac arrest (OHCA). This beneficial effect may be limited to the subgroup of ST-segment elevation myocardial infarction (STEMI) patients.

Methods: To assess the impact of pre-hospital heparin loading on TIMI (Thrombolysis in Myocardial Infarction) flow grade and mortality in STEMI patients with OHCA, we analyzed data from 2,566 consecutive patients from two hospitals participating in the prospective Feedback Intervention and Treatment Times in ST-segment Elevation Myocardial Infarction (FITT-STEMI) trial.

Accredited cardiac arrest centers facilitate eCPR and improve neurological outcome.

Background: Out-of-hospital cardiac arrest (OHCA) remains a frequent medical emergency with low survival rates even after a return of spontaneous circulation (ROSC). Growing evidence supports formation of dedicated teams in scenarios like cardiogenic shock to improve prognosis. Thus, the European Resuscitation Council (ERC) recommended introduction of Cardiac Arrest Centers (CAC) in their 2015 guidelines.

Infarct-Related Artery as a Donor of Collaterals in ST-Segment-Elevation Myocardial Infarction With Concomitant Chronic Total Occlusion: Challenge of the Double-Jeopardy Thesis.

BACKGROUND In ST-segment-elevation myocardial infarction (STEMI), a concomitant chronic total occlusion (CTO) in a non-infarct-related artery (NIRA) is associated with adverse outcome. In the case of the infarct-related artery (IRA) as a donor vessel for collaterals to the CTO, the IRA occlusion may lead to an acute threat to both the immediate IRA and the collaterally supplied CTO area, which has been described as a double-jeopardy effect. METHODS AND RESULTS We investigated the role of preformed intercoronary collaterals to the CTO originating from either the IRA or NIRA.

Patient delay and benefit of timely reperfusion in ST-segment elevation myocardial infarction.

Background: In patients with ST-segment elevation myocardial infarction (STEMI), it is unknown how patient delay modulates the beneficial effects of timely reperfusion.

Aims: To assess the prognostic significance of a contact-to-balloon time of less than 90 min on in-hospital mortality in different categories of symptom-onset-to-first-medical-contact (S2C) times.

Methods: A total of 20 005 consecutive patients from the Feedback Intervention and Treatment Times in ST-segment Elevation Myocardial Infarction (FITT-STEMI) programme treated with primary percutaneous coronary intervention (PCI) were included.

Long-term effects of a standardized feedback-driven quality improvement program for timely reperfusion therapy in regional STEMI care networks.

Aims: Current European Society of Cardiology guidelines state that repetitive monitoring and feedback should be implemented for ST-elevation myocardial infarction (STEMI) treatment, but no evidence is available supporting this recommendation. We aimed to analyze the long-term effects of a formalized data assessment and systematic feedback on performance and mortality within the prospective, multicenter Feedback Intervention and Treatment Times in STEMI (FITT-STEMI) study.

Methods: Regular interactive feedback sessions with local STEMI management teams were performed at six participating German percutaneous coronary intervention (PCI) centers over a 10-year period starting from October 2007.

Impact of COVID-19 outbreak on regional STEMI care in Germany.

Aims: To assess the impact of the lockdown due to coronavirus disease 2019 (COVID-19) on key quality indicators for the treatment of ST-segment elevation myocardial infarction (STEMI) patients.

Methods: Data were obtained from 41 hospitals participating in the prospective Feedback Intervention and Treatment Times in ST-Elevation Myocardial Infarction (FITT-STEMI) study, including 15,800 patients treated for acute STEMI from January 2017 to the end of March 2020.

Results: There was a 12.

Prognostic significance of emergency department bypass in stable and unstable patients with ST-segment elevation myocardial infarction.

Background: In ST-segment elevation myocardial infarction (STEMI) patients treated with percutaneous coronary intervention, direct transport from the scene to the catheterisation laboratory bypassing the emergency department has been shown to shorten times to reperfusion. The aim of this study was to investigate the effects of emergency department bypass on mortality in both haemodynamically stable and unstable STEMI patients.

Methods: The analysis is based on a large cohort of STEMI patients prospectively included in the German multicentre Feedback Intervention and Treatment Times in ST-Elevation Myocardial Infarction (FITT-STEMI) trial.

Impact of treatment delay on mortality in ST-segment elevation myocardial infarction (STEMI) patients presenting with and without haemodynamic instability: results from the German prospective, multicentre FITT-STEMI trial.

Aims: The aim of this study was to investigate the effect of contact-to-balloon time on mortality in ST-segment elevation myocardial infarction (STEMI) patients with and without haemodynamic instability.

Methods And Results: Using data from the prospective, multicentre Feedback Intervention and Treatment Times in ST-Elevation Myocardial Infarction (FITT-STEMI) trial, we assessed the prognostic relevance of first medical contact-to-balloon time in n = 12 675 STEMI patients who used emergency medical service transportation and were treated with primary percutaneous coronary intervention (PCI). Patients were stratified by cardiogenic shock (CS) and out-of-hospital cardiac arrest (OHCA).

[Optimizing systems of care for patients with acute myocardial infarction. STEMI networks, telemetry ECG, and standardized quality improvement with systematic data feedback].

Rapid revascularization of the infarct-related artery importantly affects prognosis in the treatment of acute ST elevation myocardial infarction (STEMI). Treatment results can be improved significantly when a STEMI-specific structure of care is created and when systematic quality improvement measures are implemented. The necessary structural measures include establishing or participating in myocardial infarction networks.

Contact-to-balloon time and door-to-balloon time after initiation of a formalized data feedback in patients with acute ST-elevation myocardial infarction.

For many patients with ST-segment elevation myocardial infarctions (STEMIs), the time from presentation to percutaneous coronary intervention exceeds established goals. This study was conducted to examine the effects of formalized data assessment and systematic feedback on treatment times. All patients with STEMIs treated with percutaneous coronary intervention in a semi-rural 3-hospital network from January 1, 2006, to December 31, 2006, were prospectively analyzed (n = 114).

[Tako-tsubo cardiomyopathy. Incidence in patients with acute coronary syndrome].

Background And Methods: In 2005, an emergency coronary angiography was performed at the authors' clinic in 215 patients (148 men, 67 women) with troponin-positive acute coronary syndrome.

Results: In five of these patients (exclusively women, mean age [+/- SD] 61 +/- 12 years), tako-tsubo cardiomyopathy was identified. This represents a frequency of 2.

Closure of an iatrogenic aortocoronary arteriovenous fistula: transcatheter balloon embolization following failed coil embolization and salvage of coils that migrated into the coronary venous system.

We report a 50-year-old patient with successful percutaneous closure of a large inadvertent surgical aortocoronary arteriovenous fistula (shunt flow: 1.8 L/min). With initial embolization of multiple coils, no lasting occlusion of the large fistula could be achieved.
