Article: [Sudden cardiac death in patients with left ventricular dysfunction from ischemic heart disease: role of the implantable defibrillator. Evidence, guidelines and good clinical judgment].
[show abstract] [hide abstract]
ABSTRACT: A number of studies have shown that the implantable cardioverter-defibrillator (ICD) is the most effective therapy for the prevention of sudden cardiac death from ventricular arrhythmias in patients with ischemic heart disease and severe left ventricular dysfunction. However, ejection fraction should not be considered the only parameter for the identification of candidates to ICD; this may lead to a "hyper-simplification" of the choices and to often unnecessary or inappropriate implantations. The purpose of this paper was to review the literature data regarding indications for ICD implantation in primary prevention in patients with severe ischemic left ventricular dysfunction by taking into account different clinical settings, in particular the biological age, the comorbidity profile, the temporal length between the ischemic event and ICD implantation, the possible impact of revascularization in reducing the arrhythmic risk.Giornale italiano di cardiologia (2006) 09/2012; 13(9):592-601. -
Article: How can optimization of medical treatment avoid unnecessary implantable cardioverter-defibrillator implantations in patients with idiopathic dilated cardiomyopathy presenting with "SCD-HeFT criteria?".

ABSTRACT: To assess the proportion and long-term outcomes of patients with idiopathic dilated cardiomyopathy and potential indications for implantable cardioverter-defibrillator before and after optimization of medical treatment, 503 consecutive patients with idiopathic dilated cardiomyopathy were evaluated from 1988 to 2006. A total of 245 patients (49%) satisfied the "Sudden Cardiac Death in Heart Failure Trial (SCD-HeFT) criteria," defined as a left ventricular ejection fraction of ≤0.35 and New York Heart Association (NYHA) class II-III on registration. Among these, 162 (group A) were re-evaluated 5.4 ± 2 months later with concurrent β-blockers and angiotensin-converting enzyme inhibitor use. Of the 162 patients, 50 (31%) still had "SCD-HeFT criteria" (group A1), 109 (67%) had an improved left ventricular ejection fraction and/or New York Heart Association class (group A2), and 3 (2%) were in NYHA class IV. Of the 227 patients without baseline "SCD-HeFT criteria" (left ventricular ejection fraction >0.35 or NYHA class I), 125 were evaluated after 5.5 ± 2 months. Of these 227 patients, 13 (10%) developed "SCD-HeFT criteria" (group B1), 111 (89%) remained without "SCD-HeFT criteria" (group B2), and 1 (1%) had worsened to NYHA class IV. The 10-year mortality/heart transplantation and sudden death/sustained ventricular arrhythmia rate was 57% and 37% in group A1, 23% and 20% in group A2 (p <0.001 for mortality/heart transplantation and p = 0.014 for sudden death/sustained ventricular arrhythmia vs group A1), 45% and 41% in group B1 (p = NS vs group A1), 16% and 14% in group B2 (p = NS vs group A2), respectively. In conclusion, two thirds of patients with idiopathic dilated cardiomyopathy and "SCD-HeFT criteria" at presentation did not maintain implantable cardioverter-defibrillator indications 3 to 9 months later with optimal medical therapy. Their long-term outcome was excellent, similar to that observed for patients who had never met the "SCD-HeFT criteria."The American journal of cardiology 12/2011; 109(5):729-35. · 3.58 Impact Factor
