OBJECTIVE: High-degree atrioventricular block (AVB), including complete AVB in acute inferior ST-elevation myocardial infarction (STEMI), is not uncommon. However, there is no study evaluating the clinical differences between patients who have undergone temporary pacing (TP) and patients who have not. The present study was designed to investigate whether TP has any prognostic significance in inferior STEMI complicated by complete AVB. METHODS: From January 2009 to December 2014, 295 consecutive patients diagnosed with inferior wall STEMI in a university hospital were reviewed...

BACKGROUND: Whether ischemic postconditioning (IPOC) immediately after routine thrombus aspiration (TA) reduces infarct size (IS) in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI) has not been established. STUDY DESIGN: The POstconditioning Rotterdam Trial (PORT) is a dual-center, prospective, open-label, randomized trial with blinded endpoint evaluation enrolling 72 subjects with first-time STEMI, and an occluded infarct-related artery (IRA) without collaterals undergoing PPCI...

In 30-60 % of patients presenting with ST-segment elevation myocardial infarction (STEMI), significant stenoses are present in one or more non-infarct-related arteries (IRA). This correlates with an increased risk of major adverse cardiac events (MACE). Current guidelines, do not recommend revascularization of non-culprit lesions unless complicated by cardiogenic shock or persistent ischemia after primary percutaneous coronary intervention (PCI). Prior observational and small randomized controlled trials (RCTs) have demonstrated conflicting results regarding the optimal revascularization strategy in STEMI patients with multivessel disease...

Primary percutaneous coronary intervention (PCI) with the implantation of new-generation drug-eluting stents (DES) is the preferred method of reperfusion in ST-segment elevation myocardial infarction (STEMI). More importantly, new-generation DES are recommended as the default option in all clinical conditions and lesion subsets. On the other hand, the interest in fully bioresorbable scaffolds (BRS) implantation, also in the setting of STEMI is growing. Also, dedicated stents technologies, i.e. mesh-covered stents and self-expanding stents may play role in the treatment of STEMI and thrombus containing lesions...

BACKGROUND: The implementation of regional primary percutaneous coronary intervention (PCI) programs has been critical in achieving timely intervention in patients with ST-segment elevation myocardial infarction (STEMI). However, 1 consequence has been inappropriate and false-positive cardiac catheterization laboratory (CCL) activations where either angiography is cancelled or no culprit lesion is found, respectively. METHODS: We performed a retrospective cohort study of 1,391 patients referred for primary PCI to a single academic center from November 2007 to August 2013...
