However, a correct diagnosis of noncompaction has important implications due to the possible association with other cardiac abnormalities and/or muscle disorders, progressive left ventricular dysfunction, risk of thromboembolism, and life-threatening arrhythmias. Furthermore, because of the familial association described with ventricular noncompaction, screening with echocardiography of first relatives is recommended. Since echocardiography is the diagnostic technique of choice, missed diagnoses may be due to nonoptimal imaging of the lateral and apical myocardium, and/or insufficient disease awareness by echocardiographers.

Sudden cardiac death is responsible for about 10% of all deaths in Italy in 2000. It is unpredictable and is related to malignant ventricular arrhythmias that may be interrupted in more than 70% of cases. Survival rates generally do not exceed 5% in out-of-hospital cardiac arrest, but, as previously reported, early defibrillation may increase survival rate by 3 times. The Italian law of April 3, 2001, and its recent amendments authorized healthcare providers and trained lay rescuers to use automated external defibrillators either for in-hospital or out-of-hospital settings. We planned a program for early defibrillation in ASL 3 in four outpatient clinics where a transit of 300,000 patients was expected in 2004. Defibrillators were placed in wall-mounted boxes. Opening of these boxes enable an automatic calling to the 118 emergency service that is able to dispatch an advanced cardiac life support team to the pertinent outpatient clinic. The system of wall-mounted boxes automatically communicates by modem with a programmable rate, the state of repair and efficiency of the single boxes, in order to simplify the control of the whole system of defibrillators. This plan of Turin ASL 3 is innovative in the metropolitan area and emphasizes the central role of the 118 emergency system in the management of out-of-hospital cardiac arrest, even in hospital settings such as outpatient clinics with a high number of old users at higher risk of cardiac events. This plan with the availability of automatic calling of the 118 emergency service will be proposed to remaining local hospital utilities for their outpatient settings as well as to other public utilities such as general stores, drugstores, airports where a significant transit mat be expected.

However, even small increases in creatine kinase (CK)-MB levels are an expression of a true and detectable infarction and may be associated with a higher follow-up mortality. The cause of CK-MB elevation in case of procedural complications is obvious; however, most cases of minor CK-MB elevation occur in patients with uncomplicated procedures with excellent final angiographic results. It has been suggested that the main mechanism explaining the occurrence of myocardial necrosis during otherwise successful coronary intervention may be distal microembolization of plaque components, an enhanced inflammatory state or total plaque burden and/or instability. Different treatments have been proposed to prevent myocardial injury during coronary intervention, including nitrate infusion, intracoronary beta-blockers, adenosine and IIb/IIa inhibitors, but none of these (apart from the use of IIb/IIIa inhibitors) have been routinely introduced into clinical practice. Previous observational studies suggested a beneficial effect of pre-treatment with statins in this setting; the ARMYDA (Atorvastatin for Reduction of Myocardial Damage During Angioplasty) trial is the first prospective, randomized, placebo-controlled study, evaluating the effects of 7-day therapy with 40 mg/day of atorvastatin on post-procedural release of markers of myocardial damage in patients with stable angina undergoing percutaneous intervention. In this study therapy with atorvastatin was associated with an 80% risk reduction in the occurrence of periprocedural myocardial infarction, as well as with a significant reduction in post-intervention peak levels of all markers of myocardial damage. The mechanisms underlying the beneficial effects of atorvastatin may be an inflammatory action reducing myocardial injury necrosis due to microembolization, an improvement in endothelial function on microcirculation, and direct myocardial protection.</p>","PeriodicalId":80290,"journal":{"name":"Italian heart journal.
