We describe a 45-year old man who experienced a potentially fatal arrhythmia after consumption of multiple energy drinks. At 5 years old, he underwent "repair" of tetralogy of Fallot using a patch in the right ventricular outflow tract, and at age 40 had an automatic implantable cardiac defibrillator (AICD) placed. ⋯ The risk of consuming energy drinks in those with underlying structural heart disease and the general population should be determined. Warning labels should be required to inform consumers of the risks posed by these drinks and of appropriate limits for consumption.

Randomized Controlled Trial Multicenter Study
Outcomes of a pharmacoinvasive strategy for successful versus failed fibrinolysis and primary percutaneous intervention in acute myocardial infarction (from the STrategic Reperfusion Early After Myocardial Infarction [STREAM] study).
Although a fibrinolytic pharmacoinvasive strategy is recommended for patients with ST elevation myocardial infarction (STEMI) unable to undergo timely primary percutaneous coronary intervention (PCI), there are limited data addressing outcomes specific to those with successful or unsuccessful pharmacologic reperfusions. Accordingly, we evaluated a contemporary pharmacoinvasive strategy for failed and successful reperfusions within the STrategic Reperfusion Early After Myocardial infarction study. Of 1,823 per-protocol-treated patients with STEMI, we examined clinical outcomes and angiographic and electrocardiographic metrics in 3 groups as follows: fibrinolysis requiring rescue (rescue, n = 348), fibrinolysis with scheduled angiography (scheduled, n = 516), and primary PCI (n = 927). ⋯ Compared with successfully reperfused patients undergoing scheduled angiography, the adjusted relative risk of the primary outcome was 2.92 (95% confidence interval 1.92 to 4.45) in rescue patients. In conclusion, pharmacoinvasive-treated patients requiring rescue angiography had greater baseline risk with more co-morbidities and worse 30-day outcomes compared with successful fibrinolytic-treated patients. Residual ST elevation after reperfusion assists in defining prognosis.

Multicenter Study
Impact of atrial fibrillation and heart failure, independent of each other and in combination, on mortality in community-dwelling older adults.
Atrial fibrillation (AF) and heart failure (HF), common in older adults, are associated with poor outcomes. However, little is known about their impact, independent of each other. We studied 5,673 community-dwelling adults aged ≥ 65 years in the Cardiovascular Health Study. ⋯ Compared with AF alone, aHR (95% CIs) associated with HF alone for all-cause, CV, and non-CV mortalities was 1.69 (1.29 to 2.23), 1.73 (1.20 to 2.51), and 1.64 (1.09 to 2.46), respectively. Compared with HF alone, those with both conditions had greater CV but not all-cause mortality. In conclusion, community-dwelling older adults with AF have greater mortality than those without but lesser than those with HF, and both conditions were associated with greater CV and all-cause mortalities, whereas only those with HF had greater non-CV mortality.

Multicenter Study Comparative Study
Comparison of risk of acute kidney injury after primary percutaneous coronary interventions with the transradial approach versus the transfemoral approach (from the PRIPITENA urban registry).
The risk of acute kidney injury (AKI) is a major issue after percutaneous coronary interventions (PCIs), especially in the setting of ST-elevation myocardial infarction. Preliminary data from large retrospective registries seem to show a reduction of AKI when a transradial (TR) approach for PCI is adopted. Little is known about the relation between vascular access and AKI after emergent PCI. ⋯ Major adverse cardiovascular events and stent thrombosis were not different among study groups, whereas major bleedings were more often seen in the TF group. At multivariate analysis, femoral access was an independent predictor of AKI (odds ratio 1.654, 95% confidence interval 1.084 to 2.524, p = 0.042). In conclusion, in this database of primary PCI, the risk of AKI was lower with a TR approach, and the TF approach was an independent predictor for the occurrence of this complication.
