    ABSTRACT: The ventricular myocardial performance index (MPI) is a feasible echocardiographic parameter for the evaluation of patients with chronic heart failure (CHF). The long-term prognostic role of right ventricular MPI (RV MPI) has been already assessed in patients with more advanced CHF but data are lacking in moderate CHF. The aim of the study is to evaluate the possible prognostic role of RV MPI in moderate CHF patients compared to others traditional RV parameters. From 2003 to 2004 we enrolled 95 consecutive NYHA class II CHF patients (65 males and 30 females), with the mean age of 66 ± 11 years with left ventricular ejection fraction (LVEF) <40%, on optimal medical treatment. All patients were evaluated clinically and by echocardiography with a follow-up of 5 years (combined end point: cardiovascular mortality and hospitalization for HF). RV MPI was 0.45 ± 0.36, tricuspid annular plane systolic excursion was 21 ± 8 mm, RV fractional area change was 42 ± 12%, systolic pulmonary artery pressure was 33 ± 9 mmHg, and acceleration time of pulmonic flow was 115.5 + 22.62 msec. After the 5 year follow-up the total mortality was 24.2% and HF hospitalization rate was 33%. At Cox multivariate analysis only an RV MPI superior to median value (>0.38) and tricuspid annular plane systolic excursion inferior to median value (<18 mm) had shown a significant prognostic role. The RV MPI in a population of moderate CHF showed to have a more long-term powerful prognostic value than other conventional and traditional echocardiographic right ventricular functional parameters.

    ABSTRACT: Diabetes is associated with increased cardiovascular mortality. The aim of our study was to determine the prognostic factors for mortality in patients with type 2 diabetes (T2DM) and coronary artery disease (CAD) who underwent coronary angiography and percutaneous coronary intervention. Four hundred and forty-five consecutive T2DM patients with significant CAD (≥ 75% stenosis) were included in our analysis. All patients underwent standard clinical examination, laboratory tests and transthoracic echocardiography with measurement of the left ventricular ejection fraction. Severity of CAD at the coronary angiography was evaluated using the Gensini score. Clinical follow-up was completed at 1, 3 and 6 years. During a mean follow-up of 73·3 ± 22·1 months, 109 patients died (24·5%). Significant determinants of an increased risk of death at multivariable analysis were age (p < 0·001), serum creatinine (p = 0·001), peripheral vascular disease (p = 0·002), serum glucose (p = 0·004), serum fibrinogen (p = 0·011) and history of heart failure (HF, p = 0·011). When all the variables were entered as categorical variables, with continuous variables split at their median value, only history of HF, estimated glomerular filtration rate, serum glucose, serum fibrinogen (all p < 0·0001) and beta-blocker therapy at discharge (p = 0·027) were selected. Our study shows a relatively good prognosis of patients with T2DM. Comorbidities, namely HF and renal impairment, are main determinants of survival.
