Assessment of E/A ratio helps emergency clinicians in the management of patients with acute dyspnea.

Acute dyspnea (AD) is one of the main reasons for admission to the Emergency Department (ED). In the last years integrated ultrasound examination (IUE) of lung, heart and inferior vena cava (IVC) has become an extension of clinical examination for a fast differential diagnosis. The aim of present study is to assess the feasibility and diagnostic accuracy of E/A ratio for diagnosing acute heart failure (aHF) in patients with acute dyspnea. We included 92 patients presenting to the ED of CTO Hospital in Naples (Italy) for AD. All patients underwent IUE of lung-heart-IVC with a portable ultrasound device. Left ventricle diastolic function was assessed using pulse wave doppler at the tips of the mitral valve and E wave velocity and E/A ratio were recorded. The FINAL diagnosis was determined by two expert reviewers: acute HF or non-acute HF (non-aHF). We used 2 × 2 contingency tables to analyze sensitivity, specificity, positive predictive and negative predictive value of ultrasound parameters for the diagnosis of AD, comparing with the FINAL diagnosis. Lung ultrasound (LUS) showed high sensitivity, good specificity and accuracy in identification of patients with aHF. However, the highest accuracy was obtained by diastolic function parameters. The E/A ratio showed the highest diagnostic performance with an AUC for aHF of 0.93. In patients presenting with AD, E/A ratio is easy to obtain in a fast ultrasound protocol and showed an excellent accuracy for diagnosis of aHF.

Impact of visit-to-visit blood pressure variability on hypertensive-mediated target organ damage and future cardiovascular events: the Campania salute network.

BACKGROUND: Exaggerated variability of blood pressure (BP) poses additional stress on cardiovascular system independent of BP average value, increasing risk of target organ damage (HMOD) and cardiovascular events. We assessed the impact of visit-to-visit variability (VVV) of BP on development of cardiovascular events and HMOD. METHODS: Standard deviation (SD) and coefficient of variability of mean SBP and DBP were calculated in 3555 patients from the Campania Salute Network registry, with available echocardiogram and more than six visits during follow-up. Values from the first visit were excluded. The impact of VVV of BP on cardiovascular events, and mediation of HMOD were assessed at final visit. RESULTS: Mean number of visits was 11 ±â€Š6 with mean interval between visits of 9.1 ±â€Š3.7 months. Mean visit-to-visit SD during follow-up was 13 ±â€Š5 for systolic and 8 ±â€Š3 mmHg for DBP; coefficients of variability were 9.7 ±â€Š3.5 and of 9.6 ±â€Š3.2, respectively. In multivariable analysis, left ventricular mass at follow-up was correlated with systolic VVV of BP independently of significant effect of age, BMI, mean SBP during follow-up and initial left ventricular mass. Follow-up GFR was inversely associated with systolic and diastolic VVV, independently of significant effect of age, mean glucose and SBP during follow-up, and initial GFR. In Cox regression, high VVV of BP was also associated with increased risk of cardiovascular events (hazard ratio 1.49, 95% confidence interval 1.08-2.06, P = 0.015), independently of significant effect of HMOD. CONCLUSION: VVV is associated with prevalent HMOD and development of cardiovascular events, independently of mean BP value during follow-up and HMOD.

Assessment of carotid cross-sectional area in hypertensive patients: phenotyping and prognostic validation in The Campania Salute Network.

Increased intima-media thickness (IMT) of common carotid artery (CA) is considered the hallmark of vascular hypertension-mediated target organ damage, even if vessel remodeling due to mechanical stress may also induce changes in diameter. We developed a method computing both diameter and IMT of CA, to assess correlates and prognostic impact of carotid cross-sectional area (CCSA) in a large registry of treated hypertensive patients. We selected 6300 hypertensive patients of the Campania Salute Network registry free of overt cardiovascular (CV) disease and with available CA ultrasound (54 ± 11 years; 57% male). CCSA was computed as:[Formula: see text]CCSA was considered high if >90th percentile of the sex-specific distribution (>48 mm2 in men and >41 mm2 in women). Patients with high CCSA were male, with older age, higher pulse pressure (PP), more prevalent obese and diabetic, with higher total and LDL cholesterol (p < 0.01 for all). During a median follow-up of 60 months (IQR 19-87), 206 incident composite major and minor CV events occurred. In Cox regression analysis high CCSA was associated with more than 100% increased risk of incident CV events ((HR 2.11, 95%CI 1.46-3.1, p < 0.0001), independently of the effect of older age, male sex, PP > 60 mmHg, presence of left ventricular hypertrophy (LVH), carotid plaque (CP), and less anti-RAS therapy (p < 0.05 for all). In treated hypertensive patients, increased CCSA is associated with worse metabolic and lipid profile and predict incident CV events, independently of high PP, presence of LVH and CP.

Arterial blood gas analysis utility in predicting lung injury in blunt chest trauma.

BACKGROUND: thoracic trauma is one of the leading causes of death in all age groups and accounts for 25-50 % of all traumatic injuries. With the term lung injury in blunt chest trauma, we identified a spectrum of conditions: lung contusion, pneumothorax and haemothorax. The aim of this study was to evaluate the utility of arterial blood gas analysis parameters in predicting lung injury in blunt chest trauma. METHODS: we included 51 patients presenting to the Emergency Department of "C.T.O." Hospital in Naples [Italy] for blunt chest trauma. The patients were assigned to the Lung Injury Group or to the Non-Lung Injury Group basing on CT scan findings. For each patient, we calculated the alveolar-arterial oxygen gradient [AaDO2], the AaDO2 augmentation, the arterial partial pressure of oxygen deficit [PaO2 Deficit] and the ratio between arterial partial pressure of oxygen and fraction of inspired oxygen [P/F]. Areas under the curve [AUC] and receiver operating characteristic [ROC] curve were used to compare the performance of each different test in relation to the detection of lung injury in blunt chest trauma. RESULTS: patients with lung injury had lower oxygen saturation, arterial partial pressure of oxygen, P/F and higher PaO2 Deficit, AaDO2, AaDO2 augmentation than patients without lung injury. PaO2 Deficit, AaDO2 and AaDO2 augmentation showed a good accuracy to predict lung injury in blunt chest trauma. CONCLUSION: our study demonstrates that the combination of different arterial blood gas analysis variables may be a fast approach for identifying patients with lung injury in the setting of blunt chest trauma in the Emergency Department.

Prognostic impact of increased pulse pressure/stroke index in a registry of hypertensive patients: the Campania Salute Network.

Objectives: Increased arterial stiffness is associated with advanced arteriosclerosis, abnormal left ventricular (LV) geometry and function. Whether increased arterial stiffness is associated with incident cardiovascular (CV) event (MACE), independent of other markers of target organ damage needs to be clarified. Methods: We selected hypertensive participants of the Campania Salute Network free of prevalent CV disease, with available echocardiogram and carotid ultrasound, ejection fraction ≥50%, and ≤ stage III Chronic Kidney Disease (n = 6907). Median follow-up was 63 months. End-point was incident MACE (fatal and non-fatal stroke and myocardial infarction, sudden cardiac death, carotid stenting and heart failure requiring hospitalization). Arterial stiffness was assessed from ratio of brachial pulse pressure/stroke index (i.e. normalized for body height in meter to 2.04 power) (PP/SVi). High PP/SVi (n = 980) was defined as >95th sex-specific percentile of the normal distribution from a reference normal population (>2.63/>2.82 mmHg/ml in men and women, respectively). Results: Patients with high PP/SVi were more likely to be women, older, diabetic, with higher systolic blood pressure (BP) and heart rate, more LV concentric geometry, left atrial dilatation and more carotid plaque (all p < .01). At given increase in SVi, patients with high PP/SVi exhibited two-fold increase in PP compared to normal PP/SVi. In Cox regression, patients with high PP/SVi had 63% increased hazard of MACE [95% CI (1.02-2.59) p = .04], independently of significant effect of older age, male sex, carotid plaque and less frequent anti-RAS therapy. Conclusions: In treated hypertensive patients, high PP/SVi predicted increased rate of MACE, independent of common confounders.

Target Organ Damage and Target Systolic Blood Pressure in Clinical Practice: The Campania Salute Network.

BACKGROUND: Lowering systolic blood pressure (SBP) below the conventional threshold (140 mm Hg) reduces left ventricular (LV) hypertrophy and incident cardiovascular (CV) events. We assessed whether different thresholds of SBP as the average value during follow-up (FU) have different impact on changes in target organ damage (TOD). METHODS: From the Campania Salute Network registry, we selected 4,148 hypertensive patients with average SBP-FU <140 mm Hg, and without history of prevalent CV or chronic kidney disease (i.e.,
