LDL-cholesterol target levels achievement in high-risk patients: An (un)expected gender bias.

BACKGROUND AND AIMS: Lowering low-density lipoprotein cholesterol (LDL-C) is the cornerstone of cardiovascular disease prevention. Collection of epidemiological data is crucial for monitoring healthcare appropriateness. This analysis aimed to evaluate the proportion of high-risk patients who achieved guidelines recommended LDL-C goal, and explore the predictors of therapeutic failure, with a focus on the role of gender. METHODS AND RESULTS: Health administrative and laboratory data from seven Local Health Districts in Tuscany were collected for residents aged ≥45 years with a history of major adverse cardiac or cerebrovascular event (MACCE) and/or type 2 diabetes mellitus (T2DM) from January 1, 2019, to January 1, 2021. The study aimed to assess the number of patients with optimal levels of LDL-C (<55 mg/dl for patients with MACCE and <70 mg/dl for patients with T2DM without MACCE). A cohort of 174 200 individuals (55% males) was analyzed and it was found that 11.6% of them achieved the target LDL-C levels. Female gender was identified as an independent predictor of LDL-C target underattainment in patients with MACCE with or without T2DM, after adjusting for age, cardiovascular risk factors, comorbidities, and district area (adjusted-IRR 0.58 ± 0.01; p < 0.001). This result was consistent in subjects without lipid-lowering therapies (adjusted-IRR 0.56 ± 0.01; p < 0.001). CONCLUSION: In an unselected cohort of high-risk individuals, females have a significantly lower probability of reaching LDL-C recommended targets. These results emphasize the need for action to implement education for clinicians and patients and to establish clinical care pathways for high-risk patients, with a special focus on women.

[The graduate school of medicine and palliative care: good news, but it's still not enough.] / La Scuola di specializzazione in medicina e cure palliative: una bella notizia, ma non è ancora abbastanza.

The recent establishment of palliative care and medicine as a medical specialty to be taught in postgraduate courses starting from the 2021/2022 academic year in Italy is certainly good news. Some doubts arise, anyway, if the academic programs will be limited to the postgraduate area instead of involving every university in the undergraduate courses. The risk is to maintain the reductionism of future physicians receiving a kind of education centered on the biomedical paradigm only. Since at least thirty years we know that there should not be a definite time marking a clear break between previous active treatments for the disease and subsequent palliative ones. Mainly in very old people affected by multiple chronic disorders a simultaneous presence of both forms of treatment should be scheduled, with increasing weight of palliation as the disease progresses and the probability of responding to active treatments becomes less and less. Unfortunately the reality of assistance in the last thirty days of life of patients suffering from cancer and/or chronic heart or lung diseases is increasingly centered on hospital settings, while the proportion of patients who are referred for hospice/palliative care in the last month of life is marginal, especially for non-cancer patients. We are going on with a health system that responds to the needs of the chronicities with the structures and pathways that are suitable for acute care: a completely different model would be needed. For over ten years palliative care in Italy has a specific regulatory reference such as that of law 38/2010, reaffirmed by the most recent law 219/2017: yet, although training is expressly provided for in these laws, we are still far from having made it, except for some sporadic cases. Now it seems that we are about to accomplish such provisions, even if starting from the roof instead of the foundations; as palliative care means multiprofessional and multidisciplinary teams a specific training program dedicated also to nurses, psychologists and physiotherapists is mandatory.

[Chronic diseases and risk of symptomatic COVID-19: results of a case-population study on a sample of patients in the Local Health Unit 'Toscana Centro' (Tuscany Region, Central Italy)]. / Malattie croniche e rischio di ammalarsi di COVID-19 sintomatica: risultati di uno studio case-population su un campione di casi in AUSL Toscana Centro.

BACKGROUND: the COVID-19 pandemic represents a challenge for health systems around the world, with just under 10,000 cases in Tuscany Region (Central Italy) and about 4,500 in the Local Health Unit (LHU) 'Toscana Centro', updated on 11 May 2020. The risk factors reported are several, including age, being male, and some chronic diseases such as hypertension, diabetes, respiratory and cardiovascular diseases. However, the relative importance of chronic diseases is still to be explored. OBJECTIVES: to evaluate the role of chronic diseases on the risk to develop clinically evident (at least mild symptomatic) forms of SARS-CoV-2 infection in the population of the LHU Toscana Centro. DESIGN: case-population study. SETTING AND PARTICIPANTS: 'case' is a subject with SARS-CoV-2 positive swab with at least mild clinical status, who lives in the LHU Toscana Centro area; 'controls' are all people residing in the LHU Toscana Centro area at 1 January 2020. People aged under 30 and patients living in nursing care homes are excluded from the analysis. MAIN OUTCOME MEASURES: the analysis assesses the effect of gender, age, neoplasm, and the main chronic diseases on the onset of an infection with at least mild symptoms by calculating odds ratios (OR) by multivariate logistic regression models (to produce adjusted OR by potential confounders). RESULTS: among the 1,840 cases, compared to the general population, the presence of males and over-60-year-old people is greater. Almost all the considered chronic diseases are more frequent among the cases, compared to the general population. A chronic patient has a 68% greater risk to be positive with at least mild symptoms. Many of the considered diseases show an effect on the risk of getting COVID-19 in a symptomatic form, which remains even adjusting by other comorbidities. The main ones include heart failure, psychiatric disorders, Parkinson's disease, and rheumatic diseases. CONCLUSIONS: these results confirm evidence already shown in other studies on COVID-19 patients and add information on the chronic diseases attributable risk in the population, referred to the symptomatic forms and adjusted by age, gender or the possible copresence of more diseases. These risk estimates should guide prevention interventions by health services in order to protect the chronic patients affected by the pathologies most at risk.

Chronic Care Model for the Management of Patients with Heart Failure in Primary Care.

We recently investigated the prognostic impact of a Chronic Care Model (CCM)-based healthcare program applied in primary care in Tuscany Region mainly run by multidisciplinary teams composed of general practitioners (GPs) and nurses. The project included proactively planned follow-up visits for each patient, individualized counselling to optimize lifestyle modifications and adherence to appropriate diagnostic and therapeutic pathways. 1761 patients with Chronic heart failure (CHF) directly enrolled by the GPs were matched with 3522 CHF controls not involved in the project. Over a 4-year follow-up in the CCM group a higher CHF hospitalization rate was found (12.1 vs 10.3 events/100 patient-years; incidence rate ratio [IRR] 1.15, p=0.0030), whereas mortality was lower (10.8 vs 12.6 events/100 patient-years; IRR 0.82, p<0.0001). The CCM status was independently associated with a 34% increase in the risk of CHF hospitalization and a 18% reduction in the risk of death (p<0.0001 for both). The CCM status was associated with a 50% increase in the rate of planned Heart failure (HF) hospitalizations whereas the rate of 1-month CHF readmissions showed no differences. Such a divergent trend could be explained by the direct involvement of GPs in the CCM program, leading them to a better awareness of patients' clinical status, and then to a more frequent use of clinical pathways and facilities, including hospitalization. It is reasonable to argue that not all hospitalizations must necessarily be considered as a poor outcome, as they often provide additional opportunities to improve therapies, optimize patient education, or define follow-up strategies. The evidence of a divergent trend between mortality and hospitalization in our population might support the clinical importance of a multidisciplinary approach for the management of patients with HF.

Diagnosis-related differences in the quality of end-of-life care: A comparison between cancer and non-cancer patients.

BACKGROUND: Cancer, chronic heart failure (CHF), and chronic obstructive pulmonary disease (COPD) in the advanced stages have similar symptom burdens and survival rates. Despite these similarities, the majority of the attention directed to improving the quality of end-of-life (EOL) care has focused on cancer. AIM: To assess the extent to which the quality of EOL care received by cancer, CHF, and COPD patients in the last month of life is diagnosis-sensitive. METHODS: This is a retrospective observational study based on administrative data. The study population includes all Tuscany region residents aged 18 years or older who died with a clinical history of cancer, CHF, or COPD. Decedents were categorized into two mutually exclusive diagnosis categories: cancer (CA) and cardiopulmonary failure (CPF). Several EOL care quality outcome measures were adopted. Multivariable generalized linear model for each outcome were performed. RESULTS: The sample included 30,217 decedents. CPF patients were about 1.5 times more likely than cancer patients to die in an acute care hospital (RR 1.59, 95% C.I.: 1.54-1.63). CPF patients were more likely to be hospitalized or admitted to the emergency department (RR 1.09, 95% C.I.: 1.07-1.10; RR 1.15, 95% C.I.: 1.13-1.18, respectively) and less likely to use hospice services (RR 0.08, 95% C.I.: 0.07-0.09) than cancer patients in the last month of life. CPF patients had a four- and two-fold higher risk of intensive care unit admission or of undergoing life-sustaining treatments, respectively, than cancer patients (RR 3.71, 95% C.I.: 3.40-4.04; RR 2.43, 95% C.I.: 2.27-2.60, respectively). CONCLUSION: The study has highlighted the presence of significant differences in the quality of EOL care received in the last month of life by COPD and CHF compared with cancer patients. Further studies are needed to better elucidate the extent and the avoidability of these diagnosis-related differences in the quality of EOL care.

Opposite trends in hospitalization and mortality after implementation of a chronic care model-based regional program for the management of patients with heart failure in primary care.

BACKGROUND: The chronic care model (CCM) is an established framework for the management of patients with chronic illness at the individual and population level. Its application has been previously shown to improve clinical outcome in several conditions, but the prognostic impact of CCM-based programs for the management of patients with chronic heart failure (HF) in primary care is still to be elucidated. METHODS: We assessed the prognostic impact of a primary-care, CCM-based project applied in Tuscany, Italy, in 1761 patients with chronic HF enrolled in a retrospective matched cohort study. The project was based on predefined working teams including general practitioners and nurses, proactively scheduled regular follow-up visitations for each patient, counseling for therapy adherence and lifestyle modifications, appropriate diagnostic and therapeutic pathways according to international guidelines, and a key supporting role of the nurses, who were responsible for the practical coordination of the follow-up. A matched group of 3522 HF subjects assisted by general practitioners not involved in the project was considered as control group. The endpoints of this study were HF hospitalization and all-cause mortality. RESULTS: Over a 4-year follow-up period, HF hospitalization rate was higher in the CCM group than the controls (12.1 vs 10.3 events/100 patient-years; incidence rate ratio 1.15[1.05-1.27], p = 0.0030). Mortality was lower in the CCM group than the controls (10.8 vs 12.6 events/100 patient-years; incidence rate ratio 0.82[0.75-0.91], p < 0.0001). In multivariable analysis, the CCM status was associated with a 34% higher risk of HF hospitalization and 18% lower risk of death (p < 0.0001 for both). The effect on HF hospitalization was mostly driven by a 50% higher rate of planned HF hospitalization. CONCLUSIONS: Implementation of a CCM-based program for the management of HF patients in primary care led to reduced mortality and increased HF hospitalization. These findings support the hypothesis that the beneficial effects of CCM on survival might be extended to patients with chronic HF followed in primary care, but also support the need for further strategies aimed at improving the management of these patients in terms of hospitalizations.

Prognostic comparison between creatinine-based glomerular filtration rate formulas for the prediction of 10-year outcome in patients with non-ST elevation acute coronary syndrome treated by percutaneous coronary intervention.

BACKGROUND:: Estimated glomerular filtration rate (eGFR) is a predictor of outcome among patients with non-ST-elevation acute coronary syndrome (NSTE-ACS), but which estimation formula provides the best long-term risk stratification in this setting is still unclear. We compared the prognostic performance of four creatinine-based formulas for the prediction of 10-year outcome in a NSTE-ACS population treated by percutaneous coronary intervention. METHODS:: In 222 NSTE-ACS patients submitted to percutaneous coronary intervention, eGFR was calculated using four formulas: Cockcroft-Gault, re-expressed modification of diet in renal disease (MDRD), chronic kidney disease epidemiology collaboration (CKD-Epi), and Mayo-quadratic. Predefined endpoints were all-cause death and a composite of cardiovascular death, non-fatal reinfarction, clinically driven repeat revascularisation, and heart failure hospitalisation. RESULTS:: The different eGFR values showed poor agreement, with prevalences of renal dysfunction ranging from 14% to 35%. Over a median follow-up of 10.2 years, eGFR calculated by the CKD-Epi and Mayo-quadratic formulas independently predicted outcome, with an increase in the risk of death and events by up to 17% and 11%, respectively, for each decrement of 10 ml/min/1.73 m2. The Cockcroft-Gault and MDRD equations showed a borderline association with mortality and did not predict events. When compared in terms of goodness of fit, discrimination and calibration, the Mayo-quadratic outperformed the other formulas for the prediction of death and the CKD-Epi showed the best performance for the prediction of events (net reclassification improvement values 0.33-0.35). CONCLUSIONS:: eGFR is an independent predictor of long-term outcome in patients with NSTE-ACS treated by percutaneous coronary intervention. The Mayo-quadratic and CKD-Epi equations might be superior to classic eGFR formulas for risk stratification in these patients.

Changes in diabetes care introduced by a Chronic Care Model-based programme in Tuscany: a 4-year cohort study.

Background: In 2010, Tuscany (Italy) implemented a Chronic Care Model (CCM)-based programme for the management of chronic diseases. The study's objective was to evaluate its impact on the care of patients with type 2 diabetes. Methods: A population-based cohort study was performed on patients with diabetes, identified by an administrative data algorithm, exposed to a CCM-based programme versus patients not exposed (8486 patients in each group). The groups were matched using a propensity score approach and observed from 2011 to 2014. The outcomes measured were: mortality rate and hazard ratio (HR), hospitalisation incidence rate (IR) (all causes and diabetes-related diseases) and incidence rate ratio (IRR), and Guideline Composite Indicator (GCI) as proxy of adherence to guidelines (IR and IRR). Stratified Cox regression analysis and conditional fixed effect Poisson regression analyses were performed to compute HR and IRR. Results: A significant improvement was observed for GCI (IRR 1.58; 95% CI 1.53­1.62) and for cardiovascular long-term complications (IRR 1.11; 95% CI 1.04­1.18). A protective effect was observed for neurological long-term complications (IRR 0.85; 95% CI 0.76­0.95), acute cardio-cerebrovascular long-term complications­stroke and ST segment elevation myocardial infarction­(IRR 0.81; 95% CI 0.71­0.92) and mortality (HR 0.88; 95% CI 0.81­0.96). Conclusion: The implementation of a CCM-based programme was followed by better management and benefits for the health status of patients. The increase in hospitalisations for cardiovascular long-term complications could engender cost-efficacy issues, but a better integrated care (GPs and specialists) and a more appropriate specialist outpatient services organisation could avoid a part of these, while still maintaining the benefits seen.

Determinants of discrepancies between two-dimensional echocardiographic methods for assessment of maximal left atrial volume.

AIMS: The determinants of discrepancies among two-dimensional echocardiographic (2D-E) methods for left atrial volume (LAV) assessment are poorly investigated. METHODS AND RESULTS: Maximal LAV was measured in 613 individuals (282 healthy subjects,180 athletes, and 151 hypertensives; age 45 ± 20 years, 62% male) using the ellipsoid model (LAVEllips), the area-length method (LAVAL), and the Simpson's rule (LAVSimps). On the basis of a mathematical model, two left atrial (LA) geometry indexes were tested as predictors of discrepancies between methods: the ratio between LA medial-lateral diameter (MLD) and LA anteroposterior diameter (APD); and the ratio between LA area in the four-chamber view and that of an ellipse with the same diameters [deviation from ellipse (DE)-coefficient]. Discrepancies among methods were consistently present in the overall population and across all study groups. MLD/APD and the DE-coefficient together predicted 76 and 68% of differences between biplane LAVAL and LAVEllips, and between biplane LAVSimps and LAVEllips, respectively. The DE-coefficient was the only determinant of LAVAL/LAVSimps difference (ß = 0.167, P < 0.0001). Body mass index was the strongest predictor of discrepancies between single-plane and biplane approaches of LAVAL (ß = 0.427, P < 0.0001) and LAVSimps (ß = 0.424, P < 0.0001). In additional analyses, biplane LAVAL showed the best agreement with LAV obtained by three-dimensional echocardiography and the best reproducibility and repeatability. CONCLUSION: LA geometry is the main determinant of inconsistencies between 2D-E methods for measuring maximal LAV. Body mass index is the strongest determinant of differences between single-plane and biplane approaches. Different 2D-E methods cannot be used interchangeably for diagnosis and follow-up. The biplane area-length method should be preferred, particularly in overweight-obese subjects.

Prospective Validation of the Decalogue, a Set of Doctor-Patient Communication Recommendations to Improve Patient Illness Experience and Mood States within a Hospital Cardiologic Ambulatory Setting.

Strategies to improve doctor-patient communication may have a beneficial impact on patient's illness experience and mood, with potential favorable clinical effects. We prospectively tested the psychometric and clinical validity of the Decalogue, a tool utilizing 10 communication recommendations for patients and physicians. The Decalogue was administered to 100 consecutive patients referred for a cardiologic consultation, whereas 49 patients served as controls. The POMS-2 questionnaire was used to measure the total mood disturbance at the end of the consultation. Structural equation modeling showed high internal consistency (Cronbach alpha 0.93), good test-retest reproducibility, and high validity of the psychometric construct (all > 0.80), suggesting a positive effect on patients' illness experience. The total mood disturbance was lower in the patients exposed to the Decalogue as compared to the controls (1.4 ± 12.1 versus 14.8 ± 27.6, p = 0.0010). In an additional questionnaire, patients in the Decalogue group showed a trend towards a better understanding of their state of health (p = 0.07). In a cardiologic ambulatory setting, the Decalogue shows good validity and reliability as a tool to improve patients' illness experience and could have a favorable impact on mood states. These effects might potentially improve patient engagement in care and adherence to therapy, as well as clinical outcome.

A new method to estimate left ventricular circumferential midwall systolic function by standard echocardiography: Concordance between models and validation by speckle tracking.

BACKGROUND: Assessment of left ventricular circumferential (LVcirc) systolic function by standard echocardiography can be performed by estimating midwall fractional shortening (mFS) and stress-corrected mFS (ScmFS). Their determination is based on spherical or cylindrical LV geometric models, which often yield discrepant values. We developed a new model based on a more realistic truncated ellipsoid (TE) LV shape, and explored the concordance between models among hypertensive patients. We also compared the relationships of different mFS and ScmFS estimates with indexes of LVcirc systolic strain. METHODS: In 364 hypertensive subjects, mFS was determined using the spherical (mFSspher), cylindrical (mFScyl), and TE model (mFSTE). Corresponding values of ScmFSspher, ScmFScyl, and ScmFSTE were obtained. Global circumferential strain (GCS) and systolic strain rate (GCSR) were also measured by speckle tracking. RESULTS: The three models showed poor concordance for the estimation of mFS, with average differences ranging between 11% and 30% and wide limits of agreement. Similar results were found for ScmFS, where reclassification rates for the identification of abnormal LVcirc systolic function ranged between 18% and 29%. When tested against strain indexes, mFSTE and ScmFSTE showed the best correlations (R=0.81 and R=0.51, p<0.0001 for both) with GCS and GCSR. Multivariable analysis confirmed that mFSTE and ScmFSTE showed the strongest independent associations with LVcirc strain measures. CONCLUSIONS: Substantial discrepancies in LVcirc midwall systolic indexes exist between different models, supporting the need of model-specific normative data. The use of the TE model might provide indexes that show the best associations with established strain measures of LVcirc systolic function.

Prognostic role of N-terminal pro-brain natriuretic peptide in asymptomatic hypertensive and diabetic patients in primary care: impact of age and gender : Results from the PROBE-HF study.

BACKGROUND: The association between natriuretic peptides and clinical outcome in asymptomatic hypertensive and diabetic patients with no clinical evidence of heart failure (HF) is still unclear. We assessed the prognostic value of NT-pro BNP, and its interactions with age and gender, in a cohort of asymptomatic, stage A/B HF hypertensive and diabetic patients enrolled in primary care. METHODS: NT-proBNP was measured in 1012 asymptomatic subjects with systemic hypertension and/or type-2 diabetes (age 66.6 ± 7.8 years, 48 % males) with no clinical evidence of HF. Patients were prospectively followed over 49.8 ± 6.7 months for the development of cardiac death, HF hospitalization, and nonfatal myocardial infarction. RESULTS: Patients with NT-proBNP above the 80th age- and gender-specific percentile showed a threefold risk of events as compared to those with NT-proBNP under this cut-off [hazard ratio 3.2 (2.6-8.3), p < 0.0001]. In multivariable analysis, NT-proBNP added independent and incremental prognostic information to a predictive model including established risk factors (p < 0.0001). After stratification by age, increased NT-proBNP predicted outcome among patients in the second and third age tertiles, but not among those in the first tertile. Increased NT-proBNP was associated with a 3.6-fold risk in women and a 2.9-fold risk in men. Addition of the gender-NT-proBNP interaction to prognostic models further improved prediction of events (p = 0.014). CONCLUSIONS: NT-proBNP measurement adds independent and incremental information for the prediction of clinical outcome in asymptomatic, stage A-B HF hypertensive and diabetic patients taken from primary care. This prognostic value might be further evident in the elderly and among women.

Gender differences in statin prescription rates, adequacy of dosing, and association of statin therapy with outcome after heart failure hospitalization: a retrospective analysis in a community setting.

PURPOSE: The existence of gender differences in the management of statin therapy among patients with chronic heart failure (HF) is still poorly investigated. We aimed at exploring the effect of gender on statin prescription rates and adequacy of dosing and on the association between statin therapy and all-cause 1-year mortality, after HF hospitalization in a community setting. METHODS: Statin prescription rates, adequacy of dosing (estimated as a PDD/DDD ratio >0.80), and 1-year mortality were retrospectively assessed in 2088 consecutive patients discharged from 5 local community hospitals with a definite diagnosis of HF after a mean length of stay of 7.6 days. The effect of gender was explored using multivariable logistic and Cox analyses adjusting to confounders. RESULTS: Women showed a lower statin prescription rate (25.7 vs 35.3%, P < 0.0001) and a lower prevalence of adequate statin dose (32.6 vs 42.3%, P < 0.0001) than men. Female gender was independently associated with a 24% lower probability of statin prescription and a 48% higher probability of inadequate statin dose. Statin prescription and adequacy of dosing were associated with 35 and 44% decreases in the risk of 1-year mortality, respectively, irrespective of gender. A nested case/control analysis confirmed that adequate statin dose was associated with 48% lower 1-year mortality, again without interaction with gender. CONCLUSIONS: In patients with chronic HF, female gender is independently associated with lower statin prescription rates and higher probability of inadequate dose. Statin therapy in these subjects is associated with improved 1-year survival in both men and women. This prognostic benefit is not affected by gender.

[Trends in occurrence, treatment, and outcomes of acute myocardial infarction in Tuscany Region (Central Italy), 1997-2010]. / Trend temporali di occorrenza, trattamento ed esiti dell'infarto miocardico acuto in Toscana, 1997-2010.

OBJECTIVES: to describe trends in attack rate, treatment, and outcomes of acute myocardial infarction (AMI) in Tuscany Region (Central Italy). DESIGN: population-based epidemiological study using the Tuscany Acute Myocardial Infarction Registry. SETTING AND PARTICIPANTS: cases have been identified by record linkage between the hospital discharge database and the mortality registry, and divided into hospitalised AMI (1997-2012) and out-of-hospital coronary deaths (1997-2010). Details on hospitalised cases based on the presence/absence of ST-segment elevation (STEMI / NSTEMI) can be detected for the period 2001-2012. MAIN OUTCOMEMEASURES: distribution by calendar time, gender, and type of event of absolute frequencies, age-standardised attack rates (per 100,000; standard Tuscany population, 2001) and percentages (standard: total hospitalised cases in 2011) of invasive cardiac procedures and 28-day case fatality in hospitalised cases. RESULTS: a reduction in both out-of-hospital coronary deaths and STEMI hospitalisations (attack rates, respectively, - 2.3% and -3.9% in males, -3.3% and -4.1% in females) and an increase in NSTEMI hospitalisations (+13.1% in males and +13.3% in females) were shown. The use of invasive cardiac procedures (PCI, coronary angiography) in hospitalised cases shows a considerable increase over time both in STEMI and in NSTEMI. The proportion, however, always remains lower in the whole period after the age of 70 and in women. The short term prognosis in hospitalised AMI cases shows an improvement over time, which, however, disappears when stratified by type of AMI. This trend is mainly related to the different weight that STEMI and NSTEMI have on incidence over time (increase in attack rates for NSTEMI and reduction for STEMI, with worst prognosis). CONCLUSIONS: results confirm the important changes in epidemiology, clinical presentation, and treatment of acute coronary disease in Tuscany, previously identified in the international literature. Differences in coronary reperfusion treatment of hospitalised cases still persist by age and gender. Additional efforts are needed to ensure equity in access to the best treatment for AMI.

Clinical epidemiology in Italian Registry of Infective Endocarditis (RIEI): Focus on age, intravascular devices and enterococci.

INTRODUCTION: The epidemiology of infective endocarditis (IE) is changing due to a number of factors, including aging and health related comorbidities and medical procedures. The aim of this study is to describe the main clinical, epidemiologic and etiologic changes of IE from a large database in Italy. METHODS: We prospectively collected episodes of IE in 17 Italian centers from July 2007 to December 2010. RESULTS: We enrolled 677 patients with definite IE, of which 24% health-care associated. Patients were male (73%) with a median age of 62 years (IQR: 49-74) and 61% had several comorbidities. One hundred and twenty-eight (19%) patients had prosthetic left side IE, 391 (58%) native left side IE, 94 (14%) device-related IE and 54 (8%) right side IE. A predisposing cardiopathy was present in 50%, while odontoiatric and non odontoiatric procedures were reported in 5% and 21% of patients respectively. Symptoms were usually atypical and precocious. The prevalent etiology was represented by Staphylococcus aureus (27%) followed by coagulase-negative staphylococci (CNS, 21%), Streptococcus viridans (15%) and enterococci (14%). CNS and enterococci were relatively more frequent in patients with intravascular devices and prosthesis and S. viridans in left native valve. Diagnosis was made by transthoracic and transesophageal echocardiography in 62% and 94% of cases, respectively. The in-hospital mortality was 14% and 1-year mortality was 21%. CONCLUSION: The epidemiology is changing in Italy, where IE more often affects older patients with comorbidities and intravascular devices, with an acute onset and including a high frequency of enterococci. There were few preceding odontoiatric procedures.

Nightmare-induced atypical midventricular tako-tsubo cardiomyopathy.

Tako-Tsubo cardiomyopathy (TTC) is a reversible cardiomyopathy characterized by acute left ventricular segmental dysfunction, whose clinical presentation resembles that of acute myocardial infarction. The syndrome often follows a psychophysical stressful event and is characterized by echocardiographic evidence of akinesia of the left ventricular mid-apical segments. Atypical echocardiographic patterns of TTC have recently been described, often triggered by emotional stressors, rather than physical. In this report, we describe a case of atypical TTC triggered by an unusual stressor (recurrent nightmare) in a 45-year-old woman, with peculiar clinical presentation and evolution characterized by persistent loss of consciousness, neurological deterioration, absence of typical symptoms of TTC, and features suggestive of a hysterical crisis.

Determinants and Regression Equations for the Calculation of z Scores of Left Ventricular Tissue Doppler Longitudinal Indexes in a Healthy Italian Pediatric Population.

Aim. We investigated the predictors of tissue Doppler left ventricular (LV) longitudinal indexes in a healthy Italian pediatric population and established normative data and regression equations for the calculation of z scores. Methods and Results. A total of 369 healthy subjects aged 1-17 years (age of 6.4 ± 1.1 years, 49.1% female) underwent echocardiography. LV peak longitudinal velocity at systole (s (')), early diastole (e (')), and late diastole (a (')) was determined by tissue Doppler. The ratio of peak early diastolic LV filling velocity to e (') was calculated. Age was the only independent determinant of s (') (ß = 0.491, p < 0.0001) and the strongest determinant of e (') (ß = 0.334, p < 0.0001) and E/e (') (ß = -0.369, p < 0.0001). Heart rate was the main determinant of a (') (ß = 0.265, p < 0.0001). Male gender showed no effects except for a weak association with lateral s ('), suggesting no need of gender-specific reference ranges. Age-specific reference ranges, regression equations, and scatterplots for the calculation of z scores were determined for each index. Conclusion. In a pediatric Italian population, age was the strongest determinant of LV longitudinal dynamics. The availability of age-specific normality data for the calculation of z scores may allow for correctly detecting LV dysfunction in pediatric pathological populations.
