OBJECTIVES We sought to assess the prognostic implications of the evolution of restrictive left ventricular filling pattern (RFP) in dilated cardiomyopathy (DCM). BACKGROUND Previous work has demonstrated that a RFP in DCM is associated with a poor prognosis. Few data are available on the prognostic implications of the evolution of this pattern. METHODS The evolution of left ventricular filling was studied by Doppler echocardiography in 110 patients with DCM. According to the left ventricular filling pattern at presentation and after 3 months of treatment, the patients were classified into three groups: Group 1A (n = 24) had persistent restrictive filling; Group 1B (n = 29) had reversible restrictive filling; and Group 2 (n = 57) had nonrestrictive filling. RESULTS During follow-up (41 +/- 20 months), mortality plus heart transplantations was significantly higher in Group 1A than in Groups 1B and 2 (p < 0.0001). On multivariate analysis, the model incorporating E wave deceleration time at 3 months was more powerful at predicting mortality with respect to this variable at baseline (p = 0.0039). Clinical improvement at 1 and 2 years was significantly more frequent in Groups 1B and 2 than in Group 1A (p < 0.0001 at 2 years). CONCLUSIONS In patients with DCM, the persistence of restrictive filling at 3 months is associated with a high mortality and transplantation rate. The patients with reversible restrictive filling have a high probability of improvement and excellent survival. Doppler echocardiographic reevaluation of these patients after 3 months of therapy gives additional prognostic information with respect to the initial study.

Background: Cardiac resynchronization therapy (CRT) has proved to be very effective in improving morbidity and mortality in patients affected with severe congestive heart failure. Its efficacy has been shown to be greater in patients with left bundle branch block (LBBB). The aim of our study was to verify if newly proposed criteria for true LBBB identify patients with a better clinical and instrumental response to CRT.

Background Few data are available in the literature regarding the characteristics and prognosis of asymptomatic patients with idiopathic dilated cardiomyopathy (DCM). Aim To determine the frequency with which patients affected by DCM are diagnosed in the asymptomatic state as well as to evaluate the natural history of such patients and the factors influencing their outcome. Moreover, we sought to compare the outcome of asymptomatic patients with that of patients with signs of overt heart failure at the time of first evaluation. Methods and results We analyzed the data of 747 patients with DCM enlisted in the Heart Muscle Disease Registry of Trieste from 1978 to 2007. We divided our population into four groups; group 1 comprised 118 asymptomatic [New York Heart Association (NYHA) I] patients without a history of congestive symptoms (16%), group 2 comprised 102 asymptomatic (NYHA I) patients (14%) with a positive anamnesis for heart failure stabilized in medical therapy, group 3 comprised 327 patients (44%) with signs of mild heart failure (NYHA II) and group 4 comprised 200 patients (26%) in NYHA III–IV. During the follow-up of 112 ± 63 months, 46 (21%) of 220 asymptomatic patients with DCM died or underwent heart transplantation. By Cox proportional model, left ventricular ejection fraction of 30% or less was a unique independent predictor either for death/heart transplantation (hazard ratio 3.15, 95% confidence interval 1.5–6.7, P = 0.003) or for sudden death/major ventricular arrhythmias (hazard ratio 3.9, 95% confidence interval 1.7–9.3, P = 0.002). Patients from group 1 had a trend for a better outcome with respect to those from group 2 (P = 0.06). In comparison with the asymptomatic patients, those with signs of overt heart failure at baseline had a worse prognosis. Conclusion The proportion of asymptomatic patients with DCM at the moment of first evaluation at our center is significant (30%). Among them, those without a previous history of heart failure had a less advanced disease and a trend for a better long-term outcome on optimal medical treatment. Therefore, early diagnosis may offer better long-term quality of life and even better survival. Further studies on larger populations are indicated.

Our goal was to set up a pilot study to explore the possible relation between the expression of p66(ShcA) and PTX3, two emerging regulators of stress response and inflammation processes, respectively, and the circulating levels of LDL-cholesterol (LDL), a factor implicated in the development of inflammation and oxidative-stress associated diseases such as atherosclerosis. p66(ShcA) and PTX3 mRNA contents were determined locally, in subcutaneous adipose specimens of non-diabetic pacemakerimplanted patients, and systemically in the circulating white blood cells (WBC) obtained from the same patients. The mean of the circulating LDL levels (125 mg/dl) was chosen as a threshold to identify two groups here considered to have high (>125 mg/dl) and low (<125 mg/dl) LDL plasma levels. Our data show that PTX3 and p66(ShcA) mRNA levels are significantly more elevated in WBCs and in adipose tissue samples of patients with high levels of LDL compared to those with low levels. Additionally, a multiple regression analysis indicates that among LDL, TG, HDL, total cholesterol, CRP, creatinine and glucose levels, the only variable significantly affecting p66(ShcA) and PTX3 mRNA expressions either in adipose tissue or in WBCs is represented by the circulating amount of LDL. In conclusion, our results suggest a potential link between the level of LDL and the expression of two genes involved in inflammation/oxidative stress pathways, i.e., p66(ShcA) and PTX3, thus contributing to further understand the mechanism through which LDL may mediate the pathogenesis of inflammation and oxidative-stress associated diseases such as atherosclerosis.

AIMS Malfunctions of cardiac implantable electronical devices (CIED) have been described after high-energy radiation therapy even in the absence of direct exposure to ionizing radiation, due to diffusion of neutrons (n) causing soft errors in inner circuits. The purpose of the study was to analyse the effect of scattered radiation on different types and models of CIED and the possible sources of malfunctions. METHODS AND RESULTS Fifty-nine explanted CIED were placed on an anthropomorphous phantom of tissue-equivalent material, and a high-energy photon (15 MV) radiotherapy course (total dose = 70 Gy) for prostate treatment was performed. All devices were interrogated before and after radiation. Radiation dose, the electromagnetic field, and neutron fluence at the CIED site were measured. Thirty-four pacemakers (PM) and 25 implantable cardioverter-defibrillators (ICD) were analysed. No malfunctions were detected before radiation. After radiation a software malfunction was evident in 13 (52%) ICD and 6 (18%) PM; no significant electromagnetic field or photon radiations were detected in the thoracic region. Neutron capture was demonstrated by the presence of the (198)Au((197)Au + n) or (192)Ir((191)Ir + n) isotope activation; it was significantly greater in ICD than in PM and non-significantly greater in damaged devices. A greater effect in St Jude PM (2/2 damaged), Boston (9/11), and St Jude ICD (3/6) and in older ICD models was observed; the year of production was not relevant in PM. CONCLUSION High-energy radiation can cause different malfunctions on CIED, particularly ICD, even without direct exposure to ionizing radiation due to scattered radiation of neutrons produced by the linear accelerator.

AIMS Left bundle branch block (LBBB) is commonly associated with heart failure. We evaluated the prevalence, incidence, and impact of LBBB on long-term outcome in young patients with heart failure affected by idiopathic dilated cardiomyopathy (DCM). METHODS AND RESULTS We included 608 patients with DCM from the Heart Muscle Disease Registry of Trieste in this retrospective analysis. At baseline electrocardiogram (ECG), 189 patients (31.1%) had LBBB. The patients with baseline LBBB had a significantly higher mortality rate than the patients without LBBB (38.6 vs. 27.9%, P = 0.002) at the univariate analysis. After a multiple covariate adjustment, the baseline LBBB was not associated with a significantly increased risk of death [hazard ratio (HR) 1.27, 95% confidence interval (CI): 0.88-1.81, P = 0.2]. Forty-seven (11.2%) patients without LBBB at baseline ECG developed LBBB during follow-up. Among these, the mortality rate was 49 vs. 25% in patients without new-onset LBBB (P = 0.001). New-onset LBBB was a strong and independent predictor of all-cause mortality (HR 3.18, 95% CI: 1.90-5.31, P < 0.001) at multivariate analysis. CONCLUSION After correcting for potential confounders, new-onset LBBB was found to be associated with an increased risk of all-cause mortality. The management of patients with new-onset LBBB may need to be more aggressive, possibly including early cardiac resynchronization therapy/implantable cardioverter-defibrillator therapy.
