Evolution of Cardiogenic Shock Management and Development of a Multidisciplinary Team-Based Approach: Ten Years Experience of a Single Center.

Background: The management of cardiogenic shock (CS) after ACS has evolved over time, and the development of a multidisciplinary team-based approach has been shown to improve outcomes, although mortality remains high. Methods: All consecutive patients with ACS-CS admitted at our CICU from March 2012 to July 2021 were included in this single-center retrospective study. In 2019, we established a "shock team" consisting of a cardiac intensivist, an interventional cardiologist, an anesthetist, and a cardiac surgeon. The primary outcome was in-hospital mortality. Results: We included 167 patients [males 67%; age 71 (61-80) years] with ischemic CS. The proportion of SCAI shock stages from A to E were 3.6%, 6.6%, 69.4%, 9.6%, and 10.8%, respectively, with a mean baseline serum lactate of 5.2 (3.1-8.8) mmol/L. Sixty-six percent of patients had severe LV dysfunction, and 76.1% needed ≥ 1 inotropic drug. Mechanical cardiac support (MCS) was pursued in 91.1% [65% IABP, 23% Impella CP, 4% VA-ECMO]. From March 2012 to July 2021, we observed a significative temporal trend in mortality reduction from 57% to 29% (OR = 0.90, p = 0.0015). Over time, CS management has changed, with a significant increase in Impella catheter use (p = 0.0005) and a greater use of dobutamine and levosimendan (p = 0.015 and p = 0.0001) as inotropic support. In-hospital mortality varied across SCAI shock stages, and the SCAI E profile was associated with a poor prognosis regardless of patient age (OR 28.50, p = 0.039). Conclusions: The temporal trend mortality reduction in CS patients is multifactorial, and it could be explained by the multidisciplinary care developed over the years.

Acute heart failure: differential diagnosis and treatment.

Acute heart failure is a heterogeneous clinical syndrome and is the first cause of unplanned hospitalization in people >65 years. Patients with heart failure may have different clinical presentations according to clinical history, pre-existing heart disease, and pattern of intravascular congestion. A comprehensive assessment of clinical, echocardiographic, and laboratory data should aid in clinical decision-making and treatment. In some cases, a more accurate evaluation of patient haemodynamics via a pulmonary artery catheter may be necessary to undertake and guide escalation and de-escalation of therapy, especially when clinical, echo, and laboratory data are inconclusive or in the presence of right ventricular dysfunction. Similarly, a pulmonary artery catheter may be useful in patients with cardiogenic shock undergoing mechanical circulatory support. With the subsequent de-escalation of therapy and haemodynamic stabilization, the implementation of guideline-directed medical therapy should be pursued to reduce the risk of subsequent heart failure hospitalization and death, paying particular attention to the recognition and treatment of residual congestion.

Pre- and in-hospital anticoagulation therapy in coronavirus disease 2019 patients: a propensity-matched analysis of in-hospital outcomes.

AIMS: To estimate if chronic anticoagulant (CAC) treatment is associated with morbidity and mortality outcomes of patients hospitalized for SARS-CoV-2 infection. METHODS: In this European multicentric cohort study, we included 1186 patients of whom 144 were on CAC (12.1%) with positive coronavirus disease 2019 testing between 1 February and 30 July 2020. The average treatment effect (ATE) analysis with a propensity score-matching (PSM) algorithm was used to estimate the impact of CAC on the primary outcomes defined as in-hospital death, major and minor bleeding events, cardiovascular complications (CCI), and acute kidney injury (AKI). We also investigated if different dosages of in-hospital heparin were associated with in-hospital survival. RESULTS: In unadjusted populations, primary outcomes were significantly higher among CAC patients compared with non-CAC patients: all-cause death (35% vs. 18% P < 0.001), major and minor bleeding (14% vs. 8% P = 0.026; 25% vs. 17% P = 0.014), CCI (27% vs. 14% P < 0.001), and AKI (42% vs. 19% P < 0.001). In ATE analysis with PSM, there was no significant association between CAC and primary outcomes except for an increased incidence of AKI (ATE +10.2%, 95% confidence interval 0.3-20.1%, P = 0.044). Conversely, in-hospital heparin, regardless of dose, was associated with a significantly higher survival compared with no anticoagulation. CONCLUSIONS: The use of CAC was not associated with the primary outcomes except for the increase in AKI. However, in the adjusted survival analysis, any dose of in-hospital anticoagulation was associated with significantly higher survival compared with no anticoagulation.

Renal effects of Sacubitril/Valsartan in heart failure with reduced ejection fraction: a real life 1-year follow-up study.

Real-life data confirming the favourable renal outcome in patients with heart failure (HF) treated with Sacubitril/Valsartan, previously found in several trials (RCTs), are still scant. We evaluated the renal effects of Sacubitril/Valsartan in a real-life sample of HF patients. Observational analysis of 54 consecutive outpatients affected by HF with reduced ejection fraction (HFrEF) and clinical indication for Sacubitril/Valsartan. Patients were evaluated at baseline (T0) and after six (T6) and twelve (T12) months after initiating Sacubitril/Valsartan and compared with a group of 30 historical controls. Mean age: 65.5 ± 11.7 years. Older patients: 29 (53.7%). Mean baseline estimated glomerular filtration rate (eGFR): 59.4 ± 19.2 ml/min/1.73 m2. Patients with chronic kidney disease (CKD), defined by an eGFR < 60 ml/min/1.73 m2, were 29 (53.7%). Sacubitril/Valsartan was less titrated in both older patients and patients with CKD. There were no changes in diuretics during follow-up. Systolic blood pressure (BP) decreased during follow-up (p = 0.014), while left ventricular ejection fraction (LVEF) slighly increased (p < 0.001). Renal function improved after 12 months compared to historical controls (p for interaction < 0.001) and a greater benefit was found in subjects aged < 65 years (p for interaction = 0.002) and patients with CKD (p for interaction = 0.009). A statistically (p = 0.009), but not clinically significant increase in serum potassium was also found, regardless of age and CKD. This is the first study focused on the renal effects of Sacubitril/Valsartan in HFrEF patients followed for 12 months in a real-life clinical context. The improved eGFR, despite lower BP, represents an important confirmation outside the peculiar world of RCTs.

[Primary cardiac lymphoma in an immunocompetent young adult: outcome with chemotherapy]. / Linfoma primitivo cardiaco in un giovane adulto immunocompetente: outcome positivo a medio termine con trattamento chemioterapico.

Primitive cardiac lymphoma (PCL) is a rare disease accounting for only 1-2% of primary cardiac tumors. Diffuse large B cell lymphoma is the most common type and shows a rapid progression with poor prognosis. The clinical presentation of PCL is nonspecific, and echocardiographic study is essential to the initial work-up. Magnetic resonance imaging and computed tomography scan are the methods of choice for the assessment of tumor extension. The definitive diagnosis is histopathology examination. Chemotherapy and radiotherapy represent the best treatment and should be started promptly after PCL diagnosis. We here report a case of PCL in a 59-year-old man complicated by pulmonary microembolism, atrial fibrillation and signs of right outflow tract obstruction.

Safety and efficacy of non-continuous echocardiography-guided pericardiocentesis: a single-center study of 478 patients.

BACKGROUND: There are limited contemporary data on the safety and efficacy of echocardiography-guided pericardiocentesis in Italy. The aim of the study was to evaluate safety and efficacy of pericardiocentesis, performed with non-continuous echocardiography monitoring. All the procedures performed at Department of Cardiovascular Disease, Ospedali Riuniti Ancona, from January 2001 to June 2013, were retrospectively analyzed to determine risks connected to the procedure and its success rate. Epidemiological data, procedure indications and etiology of the effusions were also recorded. METHODS: In the study period, 478 pericardiocentesis were performed for cardiac tamponade (N.=161), to remove large amount of fluid (N.=215) or for diagnostic purposes (N.=102). Echocardiographic evaluation, performed just before the procedure, was used to define the site of entry, to measure the distance from the skin to the fluid, and to establish how to direct the needle. RESULTS: We observed an extremely low rate of complications (<1%), without any death. The procedure was fully successful in 98% of cases and achieved only partial fluid removal in the remained 10 patients. The etiology of the effusion was malignancy or post cardiothoracic surgery in almost 60% of cases. Over the years there was an increase of pericardiocentesis performed after a cardiothoracic surgery (P=0.002); There was a significant reduction of the average amount of drained fluid in the years 2010-2013 vs. the period 2001-2009. CONCLUSIONS: Echocardiography-guided pericardiocentesis is an effective and safe procedure, with a low rate of complications.

The functional HERG variant 897T is associated with Conn's adenoma.

OBJECTIVE: Aldosterone secreting adenomas (aldosteronomas) have an unknown molecular origin. Ion channel currents are involved in signal transduction leading to aldosterone synthesis and secretion. HERG (human-ether-a-go-go-related gene) encodes for a potassium channel responsible for the outward rectifying delayed current and it is mutation prone. When mutated it causes most of the familial forms of both long QT and short QT syndromes. Abnormal repolarization in glomerulosa cells might increase aldosterone secretion or induce a proliferative advantage. The aims of this study were to: (1) evaluate HERG expression in aldosteronomas; (2) search for HERG somatic mutations; and (3) determine whether there is any relationship between the common HERG functional variant (A2690C, leading from lysine 897 to threonine, K897T) and aldosteronoma. DESIGN AND METHODS: Aldosteronoma and blood samples from 17 patients were studied to evaluate HERG expression, full-length HERG complementary DNA sequencing, and genotyping for K897T alleles. The prevalence of HERG 897 alleles was also tested in a control population and a population consisting entirely of hypertensive individuals. RESULTS: HERG was expressed in all aldosteronomas analysed. HERG somatic mutations were not detected. The 897T variant of HERG was significantly more common among patients with aldosteronoma (897T allele 41%) than in patients with moderate-severe essential hypertension (897T allele 20%, P = 0.007) or in the control population (897T allele 12%, P < 0.0001). The 897T/T genotype was present in 24% of the aldosteronoma patients versus 7% (P = 0.040) and 3% (P = 0.001) in essential hypertension and in the control population, respectively. When the chi test was performed considering the three groups together, the significance was similar (for alleles P < 0.0001 and for genotypes P = 0.004). CONCLUSION: The common functional HERG variant 897T may predispose to the development of aldosteronoma.
