IGFBP7 and GDF-15, but not P1NP, are associated with cardiac alterations and 10-year outcome in an elderly community-based study.

BACKGROUND: Little is known about the clinical value of Insulin-like growth factor-binding protein-7 (IGFBP7), a cellular senescence marker, in an elderly general population with multiple co-morbidities and high prevalence of asymptomatic cardiovascular ventricular dysfunction. Inflammation and fibrosis are hallmarks of cardiac aging and remodelling. Therefore, we assessed the clinical performance of IGFBP7 and two other biomarkers reflecting these pathogenic pathways, the growth differentiation factor-15 (GFD-15) and amino-terminal propeptide of type I procollagen (P1NP), for their association with cardiac phenotypes and outcomes in the PREDICTOR study. METHODS: 2001 community-dwelling subjects aged 65-84 years who had undergone centrally-read echocardiography, were selected through administrative registries. Atrial fibrillation (AF) and 4 echocardiographic patterns were assessed: E/e' (> 8), enlarged left atrial area, left ventricular hypertrophy (LVH) and reduced midwall circumference shortening (MFS). All-cause and cardiovascular mortality and hospitalization were recorded over a median follow-up of 10.6 years. RESULTS: IGFBP7 and GDF-15, but not P1NP, were independently associated with prevalent AF and echocardiographic variables after adjusting for age and sex. After adjustment for clinical risk factors and cardiac patterns or NT-proBNP and hsTnT, both IGFBP7 and GDF-15 independently predicted all-cause mortality, hazard ratios 2.13[1.08-4.22] and 2.03[1.62-2.56] per unit increase of Ln-transformed markers, respectively. CONCLUSIONS: In a community-based elderly cohort, IGFBP7 and GDF-15 appear associated to cardiac alterations as well as to 10-year risk of all-cause mortality.

Evaluation of the appropriateness of the preclinical phase (stage A and stage B) of heart failure Management in Outpatient clinics in Italy rationale and design of the 'VASTISSIMO' study.

Early detection of heart failure, when still preclinical, is fundamental. Therefore, it is important to assess whether preclinical heart failure management by cardiologists is adequate. The VASTISSIMO study ('EValuation of the AppropriateneSs of The preclInical phase (Stage A and Stage B) of heart failure Management in Outpatient clinics in Italy') is a prospective nationwide study aimed to evaluate the appropriateness of diagnosis and management of preclinical heart failure (stages A and B) by cardiologists working in outpatient clinics in Italy. Secondary goals are to verify if an online educational course for cardiologists can improve management of preclinical heart failure, and evaluate how well cardiologists are aware of patients' adherence to medications. The study involves 80 outpatient cardiology clinics distributed throughout Italy, affiliated either to the Hospital Cardiologists Association or to the Regional Association of Outpatient Cardiologists, and is designed with two phases of consecutive outpatient enrolment each lasting 1 month. In phase 1, physicians' awareness of the risk of heart failure and their decision-making process are recorded. Subsequently, half of the cardiologists are randomized to undergo an online educational course aimed to improve preclinical heart failure management through implementation of guideline recommendations. At the end of the course, all cardiologists are evaluated (phase 2) to see whether changes in clinical management have occurred in those who underwent the educational program versus those who did not. Patients' adherence to prescribed medications will be assessed through the Morisky Self-report Questionnaire. This study should provide valuable information about cardiologists' awareness of preclinical heart failure and the appropriateness of clinical practice in outpatient cardiology clinics in Italy.

Inappropriately high left-ventricular mass in asymptomatic mild-moderate aortic stenosis.

OBJECTIVE: In some patients with aortic stenosis left-ventricular hypertrophy exceeds what is needed to sustain the hemodynamic load imposed by the aortic stenosis, a condition named inappropriately high left-ventricular mass (iLVM). Although iLVM is associated with increased mortality after aortic valve replacement, prevalence and covariates of iLVM in asymptomatic aortic stenosis are unknown. METHODS: We analyzed baseline data from 1614 patients (67 ±â€Š10 years, 51% hypertensive) recruited in the Simvastatin Ezetimibe in Aortic Stenosis study evaluating placebo-controlled combined simvastatin and ezetimibe treatment in asymptomatic mild-moderate aortic stenosis. iLVM was diagnosed by Doppler echocardiography as LVM greater than 28% of the expected LVM predicted from height, sex and stroke work. RESULTS: iLVM was detected in 268 patients (16.6%), irrespective of concomitant hypertension. Patients with iLVM had higher body weight, LVM and relative wall thickness, higher prevalence of systolic dysfunction (88 vs. 15%) and lower left-ventricular afterload (all P < 0.01) than patients with appropriate LVM in spite of comparable aortic stenosis severity. In multivariate analysis, all these five variables were independently associated with iLVM. The simple coexistence of low stress-corrected midwall shortening and left-ventricular hypertrophy was the best clinical model describing iLVM phenotype (sensitivity 72%, specificity 96%, area under the receiver operating characteristic curve 0.954). CONCLUSION: iLVM is common in asymptomatic mild-moderate aortic stenosis and unrelated to severity of aortic stenosis or presence of hypertension. iLVM was associated with combined concentric geometry and reduced left-ventricular myocardial contractility, suggesting iLVM in asymptomatic aortic stenosis as a marker of more advanced myocardial disease.

An analysis of the management of cardiovascular risk factors in routine clinical practice in Italy: an overview of the main findings of the EFFECTUS study.

Cardiovascular diseases represent the leading cause of morbidity and mortality, worldwide. Early detection and appropriate management of cardiovascular risk factors and disease markers in daily clinical practice may improve preventive strategies and reduce the burden of cardiovascular disease. The EFFECTUS (Evaluation of Final Feasible Effect of Control Training and Ultra Sensitisation) programme was an educational programme aimed at evaluating prevalence of major cardiovascular risk factors among outpatients, and preferences and attitudes for cardiovascular disease management among Italian physicians in their routine clinical practice. This article provides an overview of the main findings of different analyses from the EFFECTUS database, which have demonstrated a high prevalence of cardiovascular risk factors, irrespective of the clinical settings and outpatient clinics in which patients were followed. Also, findings from this database suggest that more intensive clinical data recording was paralleled by better adherence to guidelines, and that use of electronic rather than conventional support for clinical data collection and registration improved accuracy in data recording, which translated into better management of patients at risk in daily clinical practice.
