SYMPTOMATIC ACUTE MYOCARDIAL INFARCTION IN A PATIENT BEARER OF HEART TRANSPLANTATION FOLLOWING ISCHEMIC HEART DISEASE
In 2005 Syeda et al. reported that the major factor limiting the long term of cardiac transplantation is the development of accelerated arteriosclerosis that occurs in the coronary arteries of the cardiac allograft. Transplant arteriosclerosis is characterized by diffuse, uniform, concentric narrowing of the artery by a fibrous proliferation of sub-intima cells. This atherosclerosis was estimate to occur in approximately 50% of patients by 5 years after transplantation. Unfortunately, as a consequence of cardiac denervation, symptoms are often atypical or completely absent. When these are present, the symptoms are those typical of effort angina. Very uncommon is the acute coronary syndrome.…
Sympathetic tone and ventricular tachycardia
Background The pathogenesis of idiopathic monomorphic ventricular tachycardia is not clear. We suppose that a lack of balance of the sympathetic system could be involved. Frequency domain analyses of the heart rate can be useful to understand autonomic system balance. Therefore we performed this evaluation on a sample of seven children affected by idiopathic monomorphic ventricular tachycardia. Methods and results We performed a Holter recording for palpitations on all the children, with an average age of 12 (range: 7-18 years). In all the patients many episodes of repeated sustained or nonsustained ventricular tachycardia were demonstrated, with an average heart rate of 170 bpm. We exclude…
Neuroprotective effect of erythropoietin and darbepoetin alfa after experimental intracerebral hemorrhage.
OBJECTIVE: Intracerebral hemorrhage (ICH) is a devastating clinical syndrome for which no truly efficacious therapy has yet been identified. In preclinical studies, erythropoietin (EPO) and its long-lasting analog, darbepoetin alfa, have been demonstrated to be neuroprotective in several models of neuronal insult. The objectives of this study were to analyze whether the systemic administration of recombinant human EPO (rHuEPO) and its long-lasting derivative darbepoetin alfa expedited functional recovery and brain damage in a rat model of ICH. METHODS: Experimental ICH was induced in rats by injecting autologous blood into the right striatum under stereotactic guidance. Subsequently, animal…
