Aldosterone levels are high early after admission for ST elevation myocardial infarction (STEMI) concomitantly with high risk of sudden death and life-threatening ventricular arrhythmia. ⋯ Early aldosterone blockade in patients presenting for primary PCI for STEMI is associated with significant reductions in rates of life-threatening arrhythmia and cardiac arrest independent of the initial risk profile, heart failure or hemodynamic status. These findings support the concept of aldosterone blockade early after STEMI, warranting further confirmation by ongoing randomized trials.

Atheroprotector role of the spleen based on the teaching of Avicenna (Ibn Sina).
Many studies have proven atherosclerosis is an inflammatory immune disease. The spleen plays an important immune role in the human body. Splenectomy is often used in several clinical disorders; but recent studies have shown that splenectomy may be effective in the development of atheroma lesions. ⋯ Therefore any disruption in the function of the spleen can lead to various diseases such as atherosclerosis. Based on his description, it is clear that Ibn Sina first described the role of spleen in prevention of atherosclerosis. In this review, we discuss the Avicenna (Ibn Sina) aspect of atheroprotector role of the spleen.

The size of the functional right ventricle of patients with Ebstein's anomaly is, according to contemporary opinion, small. However, the in vivo size of the functional right ventricle in patients with Ebstein's anomaly is unknown. Furthermore, it is unknown how the apical displacement and regurgitant fraction of the tricuspid valve in Ebstein's anomaly affects the size of the functional right ventricle. Therefore the primary aim of this study was to determine the volume of the functional right ventricle in patients with Ebstein's anomaly. The secondary aim of this study was to assess correlation of the volume of the functional right ventricle to the apical displacement and regurgitant fraction of the tricuspid valve. ⋯ Patients with untreated Ebstein's anomaly have large functional right ventricles. The size of the enlarged functional right ventricle seems to depend on the degree of tricuspid valve regurgitation and not on the size of the atrialized right ventricle or the age of the patient.

Review Meta Analysis Comparative Study
Right versus left radial artery access for coronary procedures: an international collaborative systematic review and meta-analysis including 5 randomized trials and 3210 patients.
Radial artery access is a mainstay in the diagnosis and treatment of coronary artery disease. However, there is uncertainty on the comparison of right versus left radial access for coronary procedures. We thus undertook a systematic review and meta-analysis comparing right versus left radial access for coronary diagnostic and interventional procedures. ⋯ Right and left radial accesses appear largely similar in their overall procedural and clinical performance during transradial diagnostic or interventional procedures. Nonetheless, left radial access can be recommended especially during the learning curve phase to reduce femoral cross-overs.
