Controlled Clinical TrialAcute effects of using an electronic nicotine-delivery device (electronic cigarette) on myocardial function: comparison with the effects of regular cigarettes.
Electronic cigarettes have been developed and marketed in recent years as smoking substitutes. However, no studies have evaluated their effects on the cardiovascular system. The purpose of this study was to examine the immediate effects of electronic cigarette use on left ventricular (LV) function, compared to the well-documented acute adverse effects of smoking. ⋯ Although acute smoking causes a delay in myocardial relaxation, electronic cigarette use has no immediate effects. Electronic cigarettes' role in tobacco harm reduction should be studied intensively in order to determine whether switching to electronic cigarette use may have long-term beneficial effects on smokers' health.

Routine angiography in survivors of out of hospital cardiac arrest with return of spontaneous circulation: a single site registry.
Coronary revascularization in resuscitated out of hospital cardiac arrest (OOHCA) patients has been associated with improved survival. ⋯ Acute myocardial infarction was the commonest cause of OOHCA and a high rate of survival to discharge was seen with a strategy of routine angiography and revascularization.

Observational StudyRelationships between obesity, glycemic control, and cardiovascular risk factors: a pooled analysis of cross-sectional data from Spanish patients with type 2 diabetes in the preinsulin stage.
Obesity is associated with the onset of type 2 diabetes mellitus (T2D), but reports conflict regarding the association between obesity and macrovascular complications. In this study, we investigated associations between cardiovascular risk factors and body mass index (BMI) and glycemic control in non-insulin-treated patients with T2D. ⋯ As insulin-naïve patients with T2D became more obese, cardiovascular risk factors became more pronounced. Higher BMI was associated with younger age and shorter duration of T2D, consistent with the notion that obesity at an early age may be key to the current T2D epidemic. Glycemic control was independent of BMI but associated with abnormal lipid levels. Further efforts should be done to improve modifiable cardiovascular risk factors.

Case ReportsComprehensive three-dimensional analysis of right-sided aortic arch with multiple vascular anomalies.
Right-sided aortic arch is a rare congenital defect usually diagnosed incidentally in adults; it is often asymptomatic unless aneurismal disease develops. In half the cases, an aberrant left subclavian artery arises from a Kommerell's diverticulum; in these cases, congenital heart anomaly is very rarely present. ⋯ Through comprehensive 3-dimensional reconstruction of the aortic arch and surrounding structures we defined anatomical relationships, which is useful for follow-up and treatment.

Effect of atorvastatin on the expression of gamma-glutamyl transferase in aortic atherosclerotic plaques of apolipoprotein E-knockout mice.
Gamma-glutamyl transpeptidase (GGT) is now considered to be one of the risk factors for cardiovascular disease. However, whether statins can alter GGT levels in arterial atheromatous plaque has not yet been studied. Therefore, the aim of this study is to determine whether statins can effectively decrease the expression of GGT in arterial atheromatous plaques. ⋯ The effect of statins on the expression of GGT in aorta plaque was firstly observed in animal model. The research shows that statins can significantly decrease the expression of GGT in aortic atherosclerotic plaques.
