Comparative Study
Impact of the body mass index on occurrence and outcome of acute ST-elevation myocardial infarction.
Obesity is a traditional risk factor for the development of cardiovascular disease. However, recent studies have described a better outcome of obese patients in the clinical course of acute coronary syndromes. We investigated the impact of the body mass index (BMI) on occurrence and outcome of acute ST-elevation myocardial infarction (STEMI). ⋯ In conclusion, our data show that obesity is a risk factor of a manifestation of STEMI at a younger age compared to normal weight patients. After STEMI has occurred, obesity is associated with a trend of a lower mortality during the following clinical course. Therefore, the focus of prevention should be the reduction of obesity and metabolic syndrome in young people, to avoid the early occurrence of STEMI by primary prevention.

Catheter-ablation of ventricular tachycardia in patients with coronary artery disease: influence of the endocardial substrate size on clinical outcome.
Ablation of symptomatic ventricular tachycardia (VT) in patients with coronary artery disease is frequently performed using the three dimensional mapping system CARTO. In the amplitude map, bipolar potentials of <1.5 mV are considered abnormal and represent damaged myocardium due to previous infarction. This pathological electrical area can be arrhythmogenic, serving as the substrate for reentrant VT. ⋯ We conclude that in patients with coronary artery disease a small area of low amplitude bipolar potentials (
