Flow mediated dilation in patient with Berlin Heart Incor left ventricle assist device.

Endothelial function measured with brachial ultrasound (BU) is a validated prognostic factor in heart failure patients. LVAD (left ventricle assist device) application is a promising surgical technique to treat refractory heart failure patients both as a bridge to heart transplantation or as destination therapy. Clinical recovery in such patients may be associated to normal endothelial function measured by BU but, as recently reported, only in pulsatile flow LVAD patients.

Acute myocardial infarction in young adults: prognostic role of angiotensin-converting enzyme, angiotensin II type I receptor, apolipoprotein E, endothelial constitutive nitric oxide synthase, and glycoprotein IIIa genetic polymorphisms at medium-term follow-up.

Background: A number of reports have investigated the association between various gene polymorphisms and the phenotypic expression of myocardial infarction. No investigations have evaluated the prognostic role of genetic factors in young people with premature coronary disease. The aim of this study was to investigate the influence of genetic factors compared with that of conventional risk factors on follow-up events in a population of Italian young adults with myocardial infarction.

Plasma activity and insertion/deletion polymorphism of angiotensin I-converting enzyme: a major risk factor and a marker of risk for coronary stent restenosis.

Background: Tissue proliferation is almost invariably observed in recurrent lesions within stents, and ACE, a factor of smooth muscle cell proliferation, may play an important role. Plasma ACE level is largely controlled by the insertion/deletion (I/D) polymorphism of the enzyme gene. The association among restenosis within coronary stents, plasma ACE level, and the I/D polymorphism is analyzed in the present prospective study.

[Diet and psychological therapy in a group of severely obese patients].

The authors evaluated the usefulness of the psychological therapy in addition to usual diet treatment. Fifty subjects with severe obesity, have been randomly assigned to two different treatment groups: a) diet; b) diet plus psychotherapy. At the end of the study only the patients treated with diet plus psychotherapy showed any highly significant body weight reduction and a better diet adherence.
