Multiple hormonal and metabolic deficiency syndrome in chronic heart failure: rationale, design, and demographic characteristics of the T.O.S.CA. Registry.

Recent evidence supports the concept that progression of chronic heart failure (CHF) depends upon an imbalance of catabolic forces over the anabolic drive. In this regard, multiple hormonal deficiency syndrome (MHDS) significantly has impacts upon CHF progression, and is associated with a worse clinical status and increased mortality. The T.O.S.CA. (Trattamento Ormonale nello Scompenso CArdiaco; Hormone Therapy in Heart Failure) Registry (clinicaltrial.gov = NCT02335801) tests the hypothesis that anabolic deficiencies reduce survival in a large population of mild-to-moderate CHF patients. The T.O.S.CA. Registry is a prospective multicenter observational study coordinated by "Federico II" University of Naples, and involves 19 centers situated throughout Italy. Thyroid hormones, insulin-like growth factor-1, total testosterone, dehydroepiandrosterone , and insulin are measured at baseline and every year for a patient-average follow-up of 3 years. Subjects with CHF are divided into two groups: patients with one or no anabolic deficiency, and patients with two or more anabolic deficiencies at baseline. The primary endpoint is the composite of all-cause mortality and cardiovascular hospitalization. Secondary endpoints include the composite of all-cause mortality and hospitalization, the composite of cardiovascular mortality and cardiovascular hospitalization, and change of VO2 peak. Patient enrollment started in April 2013, and was completed in July 2017. Demographics and main clinical characteristics of enrolled patients are provided in this article. Detailed cross-sectional results will be available in late 2018. The T.O.S.CA. Registry represents the most robust prospective observational trial on MHDS in the field of CHF. The study findings will advance our knowledge with regard to the intimate mechanisms of CHF progression and hopefully pave the way for future randomized clinical trials of single or multiple hormonal replacement therapies in CHF.

Implementing an ICT-Based Polypharmacy Management Program in Italy.

Although there is evidence of a growing awareness of the problem, no official policy statements or regulatory guidelines on polypharmacy have been released up to date by Italian Health Authorities. Medication review, application of appropriateness criteria and computerized prescription support systems are all possible approaches in order to improve the quality of prescribing in older persons. More focused training courses on multimorbidity and polytherapy management are encouraged. Furthermore a multidisciplinary approach integrating different health care professionals (physicians, pharmacists, and nurses) may positively impact on reducing the sense of fear related to discontinue or substitute drugs prescribed by others; the fragmentation of therapy among different specialists; reducing costs; and improving adverse drug reaction detection and reporting. Aiming at achieving the individualized pharmacotherapy, a multidisciplinary approach starting with identification of patients and risk for drug-related problems, followed by medication review overtime and use of inappropriateness criteria, supported by computerized systems has been proposed.

Assessment of cardiovascular impairment in obese patients: Limitations and troubleshooting of available imaging tools / Evaluación de la insuficiencia cardiovascular en pacientes obesos: limitaciones y resolución de problemas de las técnicas de imagen disponibles

The prevalence and severity of obesity have increased over recent decades, reaching worldwide epidemics. Obesity is associated to coronary artery disease and other risk factors, including hypertension, heart failure and atrial fibrillation, which are all increased in the setting of obesity. Several noninvasive cardiac imaging modalities, such as echocardiography, cardiac computed tomography, magnetic resonance and cardiac gated single-photon emission computed tomography, are available in assessing coronary artery disease and myocardial dysfunction. Yet, in patients with excess adiposity the diagnostic accuracy of these techniques may be limited due to some issues. In this review, we analyze challenges and possibilities to find the optimal cardiac imaging approach to obese population (AU)

La prevalencia y la severidad de la obesidad se han incrementado en las últimas décadas, alcanzando el grado de epidemia a nivel mundial. La obesidad se asocia a enfermedades arteriales coronarias y otros factores de riesgo, incluyendo hipertensión, insuficiencia cardiaca y fibrilación auricular, que se incrementan en los casos de obesidad. Se dispone de diversas técnicas de imagen cardiaca no invasivas, tales como ecocardiografía, tomografía computarizada cardiaca, resonancia magnética y tomografía computarizada de emisión de fotón único cardiaca, para evaluar las enfermedades arteriales coronarias y la disfunción miocárdica. Sin embargo, en pacientes con exceso de adiposidad, la precisión diagnóstica de estas técnicas puede verse limitada debido a diversas cuestiones. En esta revisión analizamos las dificultades y las posibilidades de encontrar la técnica de imagen óptima en la población obesa (AU)

Reclassification of cardiovascular risk by myocardial perfusion imaging in diabetic patients with abnormal resting electrocardiogram.

BACKGROUND AND AIMS: Despite an extensive use of stress myocardial perfusion single-photon emission computed tomography (MPS), no study addressed the role of perfusion imaging in diabetic patients with abnormal resting electrocardiogram (ECG). We compared analytical approaches to assess the added value of stress MPS variables in estimating coronary heart disease outcomes in diabetic patients with abnormal resting ECG. METHODS AND RESULTS: A total of 416 patients with diabetes and abnormal resting ECG who underwent stress MPS were prospectively followed up after the index study. The end point was the occurrence of a major cardiac event, including cardiac death and nonfatal myocardial infarction. At the end of follow-up (median 58 months), 42 patients experienced events. MPS data increased the predictive value of a model including traditional cardiovascular risk factors and left ventricular (LV) ejection fraction (likelihood ratio χ² from 17.54 to 24.15, p < 0.05, with a C statistic of 0.72, 95% confidence interval: 0.65-0.79). The addition of MPS data resulted in reclassification of 25% of the sample with a net reclassification improvement of 0.20 (95% confidence interval: 0.05-0.36). Overall, 63 patients were reclassified to a lower risk category, with a 5-year event rate of 3.5%, and 40 patients were reclassified to a higher risk category, with a 5-year event rate of 20%. CONCLUSION: The addition of MPS findings to a model based on traditional cardiovascular risk factors and LV ejection fraction improves risk classification for incident cardiac events in diabetic patients with abnormal resting ECG.
