The Role of the Recovery Room in Improving Adherence During an Enhanced Recovery After Surgery (ERAS) Implementation Program for Colorectal Surgery: A Single-Center Retrospective Analysis.

PURPOSE: The purpose of thisstudy was to evaluate the clinical impact of the Recovery Room (RR) in an Enhanced Recovery After Surgery (ERAS) pathway in colorectal surgery. DESIGN: Single-center retrospective study. METHODS: From November 2019 until September 2021, a total of 149 consecutive patients that underwent to colon-rectal surgery were enrolled. The patients were divided into two study groups: RR Group if admitted to RR after surgery, and no-Recovery Room (NRR) Group if monitored directly on the ward, bypassing the RR. The postoperative ERAS items adherence was assessed in the two study groups. FINDINGS: Final analysis included 119 patients in the RR Group and 30 patients in NRR Group. Patients that started clear liquid oral intake within two hours postoperatively were 118 in the RR group and 19 in the NRR group (99.1% vs 63.3%, P < .001). A total of 98 patients and 18 patients were mobilized on day 0 in the RR group and in NRR group, respectively (84.4% vs 15.5%, P < .05). In the RR group, postoperative adherence to the ERAS protocol components was higher in comparison with the NRR group (P < .003); adherence to the all protocol components was also higher (P < .004). CONCLUSIONS: Among patients undergoing colorectal surgery admitted to RR after surgery, the RR nurse guaranteed effective patient assistance and ensured appropriate compliance to the postoperative ERAS items.

[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.

Speckle tracking echocardiography and right ventricle dysfunction in acute respiratory distress syndrome a pilot study.

PURPOSE: Speckle tracking echocardiography is a novel echocardiographic technique to assess RV myocardial function but no data are so far available in patients with acute respiratory distress syndrome (ARDS), and we aimed at assessing the feasibility of 2 dimensional (2D) speckle tracking echocardiography and the prognostic role of RV free wall speckle tracking strain in 30 consecutive patients with moderate-severe ARDS MATERIALS AND METHODS: In an observational prospective study, 30 consecutive patients with moderate-severe ARDS were enrolled. Echocardiography was performed within 12 hours from ICU admission. RESULTS: Mortality rate was 33% (10/30). Non-survivors showed lower values of pH (7.32 ± 0.09, P = 0.03) and higher troponin I levels (0.32 (0.08-0.46), P = 0.04), NT-pro BNP (3091 (2662-7128), P = 0.009), and SAPS II (60.3 ± 9.6, P < 0.001). At echocardiographic examination, non-survivors showed lower values of TAPSE (18.3 ± 3, P = 0.034) and higher systolic pulmonary arterial pressure (49.6 ± 16, P = 0.05). Two patients (6.6%) did not show valid acoustic windows. Only three patients showed normal values of RV strain free wall (22%, 25%, and 28% absolute values, respectively), among whom one patient died. When compared to survivors, non-survivors showed significantly lower values of RV strain free wall (-10.4 ± 0.10, P < 0.001). CONCLUSIONS: In mechanically ventilated moderate-severe ARDS, 2D speckle tracking is feasible even though difficult acoustic windows are common. Further studies are needed to confirm our findings in a larger cohort of patients.

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.

Clinical impact of recovery room on post-operative walking performance in elderly patients submitted to hip surgery: a real-world analysis.

BACKGROUND: Strategies aimed at favouring functional recovery after surgery for hip fracture may be of clinical importance. AIMS: To test the clinical utility of a recovery room (RR) in terms of postoperative walking performance in an elderly population submitted to hip fracture surgery. METHODS: Postoperative walking performance at rollator was assessed in 242 consecutive orthogeriatric patients able to follow the institutional physiotherapy protocol starting on day 1 after hip surgery. Group 1 (n = 186, age 86.0 ± 9.3 years, 24.7% male) was admitted to the RR for postoperative monitoring, whereas Group 2 (n = 56, age 85.2 ± 5.7 years, 23.2% male) was directly admitted to the ward. The best performance observed during the first three postoperative days was considered. RESULTS: Group 1 showed a better walking performance than Group 2, with a 50% lower probability of walking < 5 m (relative risk 0.51, p = 0.0005) and a two-fold higher probability of walking > 10 m (relative risk 2.10, p = 0.0005). Multivariable analysis confirmed a favourable independent effect of the RR stay on walking performance (ß = 0.205, p = 0.005). DISCUSSION: Admission to the RR in elderly patients submitted to hip fracture surgery could have an independent beneficial effect on postoperative walking functional recovery. This beneficial effect could probably depend on the possibility of ensuring a more rapid management of postoperative issues CONCLUSIONS: These findings support the clinical utility of a RR implementation in facilities where hip surgery in elderly subjects is routinely performed.

Left ventricular hypertrophy or storage disease? the incremental value of speckle tracking strain bull's-eye.

Left ventricular hypertrophy (LVH) develops in response to a variety of physical, genetic, and biochemical stimuli and represents the early stage of ventricular remodeling. In patients with LVH, subclinical left ventricular (LV) dysfunction despite normal ejection fraction (EF) may be present before the onset of symptoms, which portends a dismal prognosis. Strain measurement with two-dimensional speckle tracking echocardiography (STE) represents a highly reproducible and accurate alternative to LVEF determination. The present review focuses on current available evidence that supports the incremental value of STE in the diagnostic and prognostic workup of LVH. When assessing the components of LV contraction, STE has an incremental value in differentiating between primary and secondary LVH and in the differential diagnosis with storage diseases. In addition, STE provides unique information for the stratification of patients with LVH, enabling to detect intrinsic myocardial dysfunction before LVEF reduction.

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.

Association of left ventricular longitudinal and circumferential systolic dysfunction with diastolic function in hypertension: a nonlinear analysis focused on the interplay with left ventricular geometry.

BACKGROUND: The relationships of left ventricular (LV) longitudinal and circumferential systolic dysfunction with diastolic performance in hypertensive patients have never been compared. METHODS AND RESULTS: In 532 asymptomatic hypertensive patients, circumferential function was assessed with the use of midwall fractional shortening (mFS) and stress-corrected mFS (SCmFS), whereas longitudinal function was assessed with the use of left atrioventricular plane displacement (AVPD) and systolic mitral annulus velocity (s'). Early diastolic annular velocity (e') and the E/e' ratio were measured. Global longitudinal and circumferential strain were determined in a subset of 210 patients. e' was linearly related to all systolic indexes (AVPD: R = 0.40; s': R = 0.39; mFS: R = 0.16; SCmFS: R = 0.17; all P < .0001), but the correlations were stronger with longitudinal indexes than with circumferential ones (P < .0001). E/e' was nonlinearly related to AVPD (R = -0.49; P < .0001) and s' (R = -0.34; P < .0001) and showed no relationship with mFS and SCmFS. Longitudinal indexes were superior to circumferential ones in predicting e' <8 cm/s, E/e' <8, and E/e' ≥13. The effect of LV geometry on LV diastolic function was evident among patients with preserved systolic longitudinal function, but was blunted among patients with impaired longitudinal function. In multivariable analyses, only longitudinal indexes remained associated with e' and E/e'. Analyses using strains provided similar results. CONCLUSIONS: In asymptomatic hypertensive subjects, LV diastolic performance is independently associated with longitudinal systolic dysfunction, but not with circumferential systolic dysfunction. Subtle longitudinal systolic impairment plays a role in mediating the effect of LV geometry on diastolic performance. These findings may support the need of critically revising the concept of isolated diastolic dysfunction in these patients.

Clinical outcome, valve dysfunction, and progressive aortic dilation in a pediatric population with isolated bicuspid aortic valve.

The aim of this study was to explore the medium-term clinical outcome and the risk of progression of aortic valve disease and aortic dilation in pediatric patients with isolated bicuspid aortic valve (BAV). 179 pediatric patients with isolated BAV were prospectively followed from January 1995 to December 2010. Patients with severe valve dysfunction at baseline were excluded. Clinical outcome included cardiac death, infective endocarditis, aortic complications, cardiac surgery and percutaneous valvuloplasty. Echocardiographic endpoints were: progression of aortic stenosis (AS) or regurgitation (AR) and progressive aortic enlargement at different levels of the aortic root, evaluated as z-score. The median age at diagnosis was 7.8 [2.7-12.0] years. After a median followup of 5.4 [2.3-9.2] years, all patients were alive. The clinical endpoint occurred in 4 (2.2 %) patients (0.41 events per 100 patient-years). A progression of AS and AR was observed in 9 (5.0 %) and 29 (16.2 %) patients, respectively. The z-scores at the end of follow-up were not significantly different from baseline at the annulus, Valsalva sinuses and sinotubular junction, whereas a slight increase was observed at the level of the ascending aorta (1.9 vs 1.5, p = 0.046). Significant progressive aortic dilation occurred in a minority of patients (10.6, 5.6, 9.5, and 19.0 % respectively). The clinical outcome in pediatric patients with isolated BAV is favourable and the progression of aortic valve dysfunction and aortic dilation is relatively slow. These findings may be taken into account to better guide risk assessment and clinical follow-up in these patients.

Clinical utility of an undersized nurse-operated recovery room in the postoperative course: results from an Italian community setting.

PURPOSE: In Europe, standardized criteria for recovery room (RR) requirements have not been established. The purpose of this study was to examine the clinical utility of an undersized nurse-operated RR in an Italian community hospital. DESIGN: Single-center observational study. METHODS: A total of 1,945 consecutive surgical patients admitted to the RR at the study institution between September 31, 2009, and August 31, 2011, were included in the study. A control group of surgical patients not admitted to the RR, matched for age, gender, American Society of Anesthesiologists score, and type of surgery were also considered. The prevalence of early adverse events occurring within 3 hours of the end of surgery was compared between the two groups. FINDINGS: Patients admitted to the RR (mean age, 73.6 ± 14.2 years; 42.2% male; and 76.3% having major surgery) showed lower prevalences of hypotension (P < .0001), hypertensive response (P < .0001), new arrhythmias requiring intervention (P = .0036), and oxygen desaturation (P < .0001) in comparison with the control group. No differences in the proportions of patients experiencing postoperative nausea and vomiting, shivering, bleeding, and respiratory events were found. The Numeric Rating Scale for pain was also significantly lower at 2 hours in the study group as compared to the control group (1 [0 to 5] vs 3 [1 to 7]; P < .0001). CONCLUSION: In this Italian community setting, an undersized nurse-operated RR contributed to a reduced prevalence of adverse postoperative events.

Prevalence and long-term predictors of left ventricular hypertrophy, late hypertension, and hypertensive response to exercise after successful aortic coarctation repair.

Controversial data exist about the long-term results of aortic coarctation (AC) repair. This study explored the prevalence and predictors of left ventricular (LV) hypertrophy, late hypertension, and hypertensive response to exercise in 48 subjects (age, 15.1 ± 9.7 years) currently followed in the authors' tertiary care hospital after successful AC repair. Data on medical history, clinical examination, rest and exercise echocardiography, and ambulatory blood pressure monitoring were collected. The time from AC repair to follow-up evaluation was 12.9 ± 9.2 years. The prevalence of LV hypertrophy ranged from 23 to 38 %, based on the criteria used to identify LV hypertrophy, and that of concentric geometry was 17 %. One sixth of the patients without residual hypertension experienced late-onset hypertension. One fourth of those who remained normotensive without medication showed a hypertensive response to exercise. Age at AC repair was the strongest independent predictor of LV hypertrophy, defined using indexation either for body surface area (odds ratio [OR], 1.03; p = 0.0090) or for height(2.7) (OR 1.02; p = 0.029), and it was the only predictor of late hypertension (OR 1.06; p = 0.0023) and hypertensive response to exercise (OR 1.09; p = 0.029). The risk of LV hypertrophy was 25 % for repair at the age of 3.4 years but rose to 50 and 75 % for repair at the ages of 5.9 and 8.4 years, respectively. Similar increases were found for the risk of late-onset hypertension and hypertensive response to exercise. A considerable risk of LV hypertrophy, late hypertension, and hypertensive response to exercise exists after successful AC repair. Older age at intervention is the most important predictor of these complications.

The clinical impact of pectoral nerve block in an 'enhanced recovery after surgery' program in breast surgery.

Background: Pectoral nerve block (PECS) is increasingly performed in breast surgery. Aim: The study evaluated the clinical impact of these blocks in the postoperative course. Patients & methods: In this case-control study, patients undergoing breast surgery with 'enhanced recovery after surgery' pathways were divided into group 1 (57 patients) in whom PECS was performed before general anesthesia, and group 2 (57 patients) in whom only general anesthesia was effected. Results: Postoperative opioid consumption (p < 0.002), pain at 32 h after surgery (p < 0.005) and the length of stay (p < 0.003) were significantly lower in group 1. Conclusion: Reducing opioid consumption and pain after surgery, PECS could favor a faster recovery with a reduction in length of stay, ensuring a higher turnover of patients undergoing breast surgery.

'Enhanced recovery after surgery' (ERAS) protocols have been recently applied in breast cancer patients in order to improve the postoperative course. However, the incidence of moderate to severe pain after breast surgery is frequent, and a multimodal approach is recommended. In this view, the interfascial plane blocks are advocated as a valid alternative to both paravertebral and epidural blockade. In this study, we evaluated the effects of these blocks on the postoperative course in patients undergoing breast surgery with ERAS protocols. We compared two patient groups: in the first, pectoral blocks were performed before general anesthesia, while in the second no block was carried out. We found that in the patient group receiving the blocks, postoperative opioid consumption (with essentially the same pain after surgery) and length of stay were significantly lower. Therefore, although more robust studies are needed to confirm our findings, these emerging locoregional techniques could favor a faster recovery in the context of ERAS in breast surgery. These results could have important clinical implications in terms of not only reducing healthcare costs but also ensuring a higher turnover of patients undergoing breast surgery.

The multidisciplinary audit in enhanced recovery after surgery (ERAS) colorectal surgery: experience in a single Italian center.

BACKGROUND: Current literature underlines the role of periodical feed-back to improve Enhanced Recovery After Surgery (ERAS) path adherence during implementation program. The aim of this retrospective study was to evaluate the clinical impact of an audit program in an ERAS path. METHODS: All elective patients submitted to elective colorectal surgery from November 2018 to January 2020 in our Institution were considered. The sample was divided into two study groups: group 1, including patients enrolled in the first sixth months of ERAS program until the first audit; group 2, patients enrolled in a time period of a six months after the first audit. RESULTS: The final analysis included 46 patients in group 1 and 64 in group 2. Group 2 showed a higher ASA Score (P<0.03), a higher prevalence of right hemicolectomy, and a lower prevalence of left hemicolectomy and anterior rectum resection (RAR) (P<0.016). Group 2 also had a lower prevalence of anastomotic leakage (AL) (P<0.004). Intraoperative normothermia (T>36 C°) in this group was achieved in a larger number of patients in comparison with group 1 (39% vs. 19.5%) (P<0.01). Group 2 experienced a higher average body temperature at admission in recovery room (RR) when compared to Group 1 (35.8 vs. 35.1 C°, P<0.01). CONCLUSIONS: Audit program may represent a useful tool to promote advantageous changes in clinical practice and to favor a better compliance to ERAS program.

Right ventricular longitudinal strain correlates well with right ventricular stroke work index in patients with advanced heart failure referred for heart transplantation.

BACKGROUND: Right ventricular (RV) systolic function has a critical role in determining the clinical outcome and success of using left ventricular assist devices (LVADs) in patients with refractory heart failure. Tissue Doppler and M-mode measurements of tricuspid systolic motion (tricuspid S' and tricuspid annular plane systolic excursion [TAPSE]) are the most currently used methods for the quantification of RV longitudinal function; RV deformation analysis by speckle-tracking echocardiography (STE) has recently allowed the analysis of global RV longitudinal function. Using cardiac catheterization as the reference standard, this study aimed at exploring the correlation between RV longitudinal function by STE and RV stroke work index (RVSWI) in patients referred for cardiac transplantation. METHODS AND RESULTS: Right-side heart catheterization and transthoracic echo Doppler were simultaneously performed in 41 patients referred for cardiac transplantation evaluation for advanced systolic heart failure. Thermodilution RV stroke volume and invasive pulmonary pressures were used to obtain RVSWI. RV longitudinal strain (RVLS) by STE was assessed averaging all segments in apical 4-chamber view (global RVLS) and by averaging RV free-wall segments (free-wall RVLS). Tricuspid S' and TAPSE were also calculated. No significant correlations were found for TAPSE or tricuspid S' with RVSWI (r = 0.14; r = 0.06; respectively). Close negative correlations between global RVLS and free-wall RVLS with the RVSWI were found (r = -0.75; r = -0.82; respectively; both P < .0001). Furthermore, free-wall RVLS demonstrated the highest diagnostic accuracy (area under the receiver operating characteristic (ROC) curve 0.90) and good sensitivity and specificity of 92% and 86%, respectively, to predict depressed RVSWI using a cutoff value of less than -11.8%. CONCLUSIONS: In a group of patients referred for heart transplantation, TAPSE and tricuspid S' did not correlate with invasively obtained RVSWI. RV longitudinal deformation analysis by STE correlated well with RVSWI, providing a better estimation of RV systolic performance.

Dilated cardiomyopathy and inclusion body myositis.

Inclusion body myositis (IBM) is the most common inflammatory myopathy after 50 years of age. In contrast to polymyositis and dermatomyositis, in which cardiac involvement is relatively common, current evidences indicate that IBM is not associated with cardiac disease. We report the case of a patient with biopsy-proven IBM who developed heart failure and major ventricular arrhythmias secondary to dilated cardiomyopathy few months after the clinical onset of IBM, and in whom no pathophysiologic causes explaining cardiac enlargement and dysfunction were found by laboratory and instrumental investigations. The hypothesis of a pathophysiologic association between the two conditions is discussed.

Prognostic value of pulsed tissue Doppler imaging for the assessment of left ventricular systolic function in patients with nonischemic dilated cardiomyopathy.

There is still some debate regarding the prognostic significance of left ventricular longitudinal systolic dysfunction as assessed by tissue Doppler (TD) imaging in patients with chronic heart failure (HF), since previous studies have included patients with postischemic wall motion abnormalities. Thus, this study was designed to ascertain whether TD-derived longitudinal systolic dysfunction may influence the outcome of patients with nonischemic chronic HF. In 200 consecutive patients with chronic HF secondary to dilated cardiomyopathy and no history of ischemic heart disease, peak systolic mitral annular velocity (S(m) ) was measured by pulsed TD at the septal and lateral annular sites. The end points were cardiac death or hospitalization for worsening HF. Mean follow-up duration was 30 months. In a time independent analysis, averaged S(m) calculated as the average of septal and lateral S(m) , resulted to be a significant predictor of outcome in the study population (area under receiver-operator characteristic curve: cardiovascular death, 0.69, P < 0.0001; cardiovascular events, 0.64, P = 0.0005). In a time-dependent analysis, average S(m) was associated with both cardiovascular death (hazard ratio 0.832, P = 0.0019) and cardiovascular events (hazard ratio 0.904, P = 0.039), independently of other clinical risk factors and echocardiographic parameters of systolic function. Septal S(m) but not lateral S(m) was independently associated with the outcome measures. In conclusion, the assessment of systolic mitral annular velocity by pulsed TD is a useful indicator for prognostic stratification of patients with nonischemic dilated cardiomyopathy and chronic HF.

Two-dimensional speckle tracking echocardiography of acute cardiac transplant rejection following pregnancy.

A 44-year-old woman, who had undergone orthotopic cardiac transplantation in 1999, presented acute allograft rejection 4 months after childbirth. Analysis of myocardial deformation by speckle tracking echocardiography showed, in contrast with traditional markers of systolic function, a strong reduction of left ventricular strain, which recovered, together with rejection, under pharmacological treatment. This case documents the potential advantages of speckle tracking echocardiography in the noninvasive management of transplant recipients.

"In Less than No Time": Feasibility of Rotational Thromboelastometry to Detect Anticoagulant Drugs Activity and to Guide Reversal Therapy.

Anticoagulant drugs (i.e., unfractionated heparin, low-molecular-weight heparins, vitamin K antagonists, and direct oral anticoagulants) are widely employed in preventing and treating venous thromboembolism (VTE), in preventing arterial thromboembolism in nonvalvular atrial fibrillation (NVAF), and in treating acute coronary diseases early. In certain situations, such as bleeding, urgent invasive procedures, and surgical settings, the evaluation of anticoagulant levels and the monitoring of reversal therapy appear essential. Standard coagulation tests (i.e., activated partial thromboplastin time (aPTT) and prothrombin time (PT)) can be normal, and the turnaround time can be long. While the role of viscoelastic hemostatic assays (VHAs), such as rotational thromboelastometry (ROTEM), has successfully increased over the years in the management of bleeding and thrombotic complications, its usefulness in detecting anticoagulants and their reversal still appears unclear.

Acute effects of low doses of ethanol on left and right ventricular function in young healthy subjects.

BACKGROUND: Moderate-to-high blood concentrations of ethanol acutely impair conventional echocardiographic measures of left ventricular (LV) performance, but the effects of low concentrations are unclear. This study explored the acute effects of low blood concentrations of ethanol on sensitive and load-independent indices of LV and right ventricular (RV) function. METHODS: This is a crossover experimental study conducted in 64 young healthy volunteers. Participants were asked to drink a light dose of Italian red wine equivalent to 0.5 mg/kg of ethanol, and an equal volume of fruit juice in separate experiments. The following measurements were taken at baseline and 60 minutes after the challenges: tissue Doppler mitral annulus systolic velocity (S') and excursion (MAPSE), early diastolic velocity (E'), its ratio to late diastolic velocity (E'/A'), and the ratio of mitral-to-myocardial early diastolic velocities (E/E'); and tricuspid annulus systolic velocity (tricuspid S') and amplitude (TAPSE), early diastolic velocity (tricuspid E'), and its ratio to late diastolic velocity (tricuspid E'/A'). RESULTS: Blood ethanol concentration after wine intake was 0.48 ± 0.06 g/l. Compared with the control challenge, ethanol yielded a decrease in all measures of LV function (S', -9.7%; E', -11.2%; E'/A', -13.4%; MAPSE, -8.8%; p < 0.05 for all). Among indices of RV function, increases in tricuspid E'/A' ratio and TAPSE were observed (+24.5% and +9.0%, respectively; p < 0.05 for both). CONCLUSIONS: Low blood concentrations of ethanol acutely impair LV function and increase some indices of RV function in young healthy individuals.

Determinants of echocardiographic left atrial volume: implications for normalcy.

AIMS: The relative role of multiple determinants of left atrial volume index (LAVi) in athletes and non-athletes is not fully defined. Thus, we decided to prospectively assess the determinants of LAVi in healthy individuals and competitive athletes over a wide age range. METHODS AND RESULTS: Four hundred and eighteen healthy individuals (mean age 41.7 ± 15.6 years, range 16-84, 65% males, 38% competitive athletes) underwent Doppler echocardiography including assessment of LAVi by the biplane area-length method and of left ventricular (LV) diastolic function including the ratio of early diastolic peak LV inflow velocity to peak myocardial early diastolic velocity (E/e'). Mean LAVi was 32.2 ± 9.0 mL/m(2) in the pooled population. LAVi was larger in athletes than in non-athletes (38.9 ± 9.6 mL/m(2) vs. 28.4 ± 5.8 mL/m(2), P < 0.0001). In the pooled population a stepwise multiple linear regression analysis identified LV end-diastolic volume index (LVEDVi) (ß = 0.378, P < 0.0001), LV mass index (LVMi) (ß = 0.260, P < 0.0001), competitive sport activity (ß = 0.258, P < 0.0001), and age (ß = 0.222, P < 0.0001) as independent determinants of LAVi (model R(2) = 0.54, P < 0.0001). By separate analyses, although LVEDVi, age, and LVMi were predictors of LAVi in both groups, body mass index and the E/e' ratio were additional predictors of LAVi only in non-athletes. CONCLUSIONS: In healthy individuals LV size, competitive sport, age, and LV mass are independent determinants of LAVi. Body mass index and the E/e' ratio affect LAVi only in non-athletes. These findings may have practical implications when assessing normalcy of LA size in the clinical setting.
