- BACKGROUND: Infective endocarditis (IE) is a significant disease characterized by high mortality and complications. The aim of this study was to evaluate the incidence/100 000 inhabitants and the in-hospital mortality/100 000 inhabitants of IE during the last 10 years in the province of Ravenna.METHODS AND RESULTS: We reviewed the public hospitals discharge database from January 2010 to December 2020 using the international classification of disease codification (ICD-9) for IE. We used the Italian national statistical institute (ISTAT) archive to estimate the number of Ravenna inhabitants/year. In 10 years, we identified a total of 407 patients with diagnosis of IE.The incidence of IE increased significantly from 6.29 cases/100 000 inhabitants in 2010 to 19.58 cases/100 000 inhabitants in 2020 ( P < 0.001). Also, the in-hospital mortality from IE increased over the same number of years, from 1.8 deaths/100 000 inhabitants in 2010 to 4.4 deaths/100 000 inhabitants in 2020 ( P < 0.001). The mortality rate (%) of IE over the years did not increase ( P = 0.565). Also, over the years there was no difference in the site of infection ( P = 0.372), irrespective of the valve localization or type, native valve ( P = 0.347) or prosthetic valve ( P = 0.145). On logistic regression analysis, age was the only predictor of in-hospital mortality (odds ratio 1.045, 95% confidence interval: 1.015; 1.075, P = 0.003).CONCLUSIONS: Ravenna-based data on IE showed increased disease incidence but unchanged mortality rate over 10 years of follow-up. Age remains the sole predictor of population-based mortality, irrespective of the nature of the valve, native or substitute, and the organism detected on microbiology.

- The presence of left ventricular (LV) diastolic dysfunction (DD) as characterized by Doppler echocardiography is associated with worse overall mortality both in symptomatic and asymptomatic patients. However, available data on this topic come from referral centers and have been obtained by different, validated algorithms for each single study. Thus, we aimed at determining the feasibility of comprehensive evaluation of LVDD in a primary care outpatient setting and at testing the concordance of different methodological approaches in grading diastolic dysfunction. Eight hundred eighty-five consecutive outpatients, in sinus rhythm, prospectively underwent Doppler echocardiography according to a predetermined protocol. Feasibility of each LV diastolic index and concordance between 3 methods to determine the degree of LVDD, namely the American Society of Echocardiography/European Association of Echocardiography (ASE/EAE) reconunendations, the Olmstead County, and the Canberra Study protocols, were tested. Feasibility of all diastolic indexes was high, ranging from 93% of Valsalva maneuver to 99% for mitral inflow and tissue Doppler parameters. Diastolic function was not classifiable in 6% to 19% of patients. The concordance for LV diastolic dysfunction degree was fair when comparing the classification of the ASE/EAE with those from Olinstead County (kappa = 0.25; reclassification rate 51%) and Canberra Study (kappa = 0.27; reclassffication rate 43.7%), and was good for the comparison betvveen the Olmstead County and Canberra classifications (kappa = 0.68, reclassification rate 27%). In conclusion, feasibility of LV diastolic function measurements is very high and grading diastolic dysfunction is possible in most patients in primary care settings. Substantial differences, however, exist when concordance is tested among 3 documented criteria, resulting in poor concordance of data interpretation and hence patient stratification and clinical management.

- Background: Current guidelines on diastolic function (DF) by the American Society of Echocardiography and the European Association of Cardiovascular Imaging (ASE/EACVI) have been disputed and two alternative algorithms have been proposed by Johansen et al. and Oh et al. We sought (a) to assess the concordance of ASE/EACVI guidelines on DF using these proposed alternative approaches and (b) to evaluate the prevalence of indeterminate diastolic dysfunction (DD) by each method, exploring means for reducing their number. Methods: We retrospectively analyzed the echocardiographic reports of 1158 outpatients including subjects at risk of heart failure without (n = 644) or with (n = 241) structural heart disease, and 273 healthy individuals. Concordance was calculated using the k coefficient and overall proportion of DD reclassification rate. The effectiveness of pulmonary vein flow (PVF), Valsalva maneuver, and left atrial volume index/late diastolic a'-ratio (LAVi/a') over indeterminate grading was assessed. Results: The DD reclassification rate was 30.1% (k = 0.35) for ASE/EACVI and OH, 36.5% (k = 0.27) for ASE/EACVI and JOHANSEN and 31.1% (k = 0.37) for OH and JOHANSEN (p < 0.0001 for all comparisons). DF could not be graded only by ASE/EACVI and OH in 9% and 11% patients, respectively. The majority of patients could be reclassified using PVF or Valsalva maneuver or LAVi/a', with the latter being the single most effective parameter. Conclusion: Inconsistencies between updated guidelines and independent approaches to assess and grade DF impede their interchangeable clinical use. The inconclusive diagnoses can be reconciled by conventional echocardiography in most patients, and LAVi/a' emerges as a simple and effective approach to this aim.
