Review Meta Analysis
Updated evidence on intracoronary abciximab in ST-elevation myocardial infarction: a systematic review and meta-analysis of randomized clinical trials.
Intracoronary (IC) abciximab administration remains a promising approach aimed to increase a drug concentration in the target area and possibly improve clinical outcomes in the setting of ST-segment elevation myocardial infarction (STEMI). The goal of this literature review and meta-analysis is to update available knowledge comparing IC and intravenous (IV) abciximab administration in STEMI patients. ⋯ Our updated meta-analysis shows that the clinical superiority of IC over IV abciximab administration in STEMI patients is no longer clear after the release of the AIDA STEMI trial results. Further research in high-risk STEMI patients is warranted to finally determine clinical advantages of IC vs IV abciximab administration.

Review Case Reports
QT interval prolongation and torsades de pointes in a patient undergoing treatment with vorinostat: a case report and review of the literature.
Vorinostat is a histone deacetylase inhibitor used in the treatment of recurrent or persistent cases of cutaneous T-cell lymphoma (CTCL). A retrospective review of 116 patients from phase I and II clinical trials who had a baseline and at least one subsequent ECG revealed that four patients had Grade 2 and one patient had Grade 3 QTc interval prolongation; however, a MEDLINE search found no reported cases of torsades de pointes (TdP) in patients treated with vorinostat. We describe the case of a 49 year-old male with a history of CTCL actively undergoing treatment with vorinostat. ⋯ Other factors implicated in this case included concurrent sertraline and doxepin therapy (both drugs have been associated with the development of TdP in overdose). The mechanism of development of TdP in this patient is postulated to be related to vorinostat use in combination with hypokalemia and concomitant treatment with medications associated with QTc prolongation. This case highlights the importance of post-market surveillance.

Review Case Reports
Epicardial fat necrosis: an uncommon etiology of chest pain.
Epicardial fat necrosis (EFN) is a rare cause of severe chest pain. We present a case of EFN successfully treated conservatively. With the advent of computed tomography and magnetic resonance imaging, the diagnosis can be made more precisely, avoiding the need for surgical intervention. We review the clinical characteristics, pathogenesis and treatment options of EFN.

In the great majority of cases the ECG pattern of early repolarization (ERP) is a benign phenomenon observed predominantly in teenagers, young adults, male athletes and the black race. The universally accepted criterion for its diagnosis is the presence, in at least two adjoining leads, of ≥ 1 mm or 0.1 mV ST segment elevation. In benign ERP reciprocal ST segment changes are possible only in lead aVR. ⋯ The management of IVF has class I indication for ICD implantation. Ablation therapy is considered additional to ICD implantation in those patients with repetitive ventricular arrhythmia. Quinidine is a highly efficient drug that prevents recurrence.

Arrhythmias play a significant role in the mortality and morbidity as well as hospitalizations of patients who carry a diagnosis of congestive heart failure. With improving survival in a world of novel medications and devices, an understanding of the pathophysiology and management of these arrhythmias is crucial. ⋯ Anti-arrhythmic drugs and implantable cardioverter-defibrillators were also beneficial in selected patients. Innovative electrophysiological techniques need to be considered in special situations.
