RESUMEN
BACKGROUND: The optimal assessment of systemic and lung decongestion during acute heart failure is not clearly defined. We evaluated whether inferior vena cava (IVC) and pulmonary ultrasound (CAVAL US) guided therapy is superior to standard care in reducing subclinical congestion at discharge in patients with AHF. METHODS: CAVAL US-AHF was an investigator-initiated, single-center, single-blind, randomized controlled trial. A daily quantitative ultrasound protocol using the 8-zone method was used and treatment was adjusted according to an algorithm. The primary endpoint was the presence of more than five B-lines and/or an increase in IVC diameter and collapsibility at discharge. And secondary endpoint exploratory outcome was the composite of readmission for HF, unplanned visit for worsening HF or death at 90 days RESULTS: Sixty patients were randomized to CAVAL US (n=30) or control (n=30). The primary endpoint was achieved in 4 patients (13.3%) in the CAVAL US group and 20 patients (66.6%) in the control group (p<0.001). A significant reduction in HF readmission, unplanned visit for worsening HF or death at 90 days was seen in the CAVAL US group (13.3% vs 36.7%; log rank p=0.038). Other endpoints such as NT-proBNP reduction at discharge showed a non-statistically significant reduction in the CAVAL US group (48% IQR 27-67 vs 37% -3-59;p=0.09). Safety outcomes were similar in both groups. CONCLUSION: IVC and lung ultrasound-guided therapy in AHF patients significantly reduced subclinical congestion at discharge. CAVAL US-AHF provides preliminary evidence for the potential use of a simple technique to guide decongestive therapy during hospitalization for AHF, which may reduce the composite outcome at 90 days.
RESUMEN
BACKGROUND: Nowadays, percutaneous procedures are expanding in use, and this comes with complications associated with the procedure itself. Cardiac tamponade is rare but may be life threatening since it can involve hemodynamic instability. It is known that after pleural effusion during a percutaneous procedure, pericardiocentesis should be used as drainage of the cavity. However, that does not achieve hemostasis in some cases, and in those patients who are hemodynamically unstable, a sealing agent to promote hemostasis might be useful, like thrombin. CASE PRESENTATION: We present a case report of 89-year-old patient with history of melanoma undergoing treatment with pembrolizumab, who attended the emergency department referring chest pain (intensity 5/10) and palpitations that have lasted hours. He had TnTUs 554/566 ng/L and an echocardiogram that showed dilated right chambers, hypertrophy and global hypokinesia of the left ventricle, increased filling pressures of the left ventricle and pulmonary hypertension. Myocarditis associated with pembrolizumab was suspected, so high dose steroids were initiated and endomyocardial biopsy was conducted, resulting in iatrogenic cardiac tamponade. To determine the etiology of the suspected myocarditis, an endomyocardial biopsy was performed. Unfortunately, an intraprocedural complication arose: pleural effusion resulting in iatrogenic cardiac tamponade, leading to hemodynamic instability. It required immediate pericardial drainage via subxiphoid puncture, obtaining a 550 mL hematic debit. Clinical manifestations raised suspicion of tamponade, prompting a bedside echocardiogram for a definitive diagnosis. Despite these efforts, the patient remained hemodynamically unstable, and due to the elevated surgical risk, intrapericardial thrombin was employed to achieve successful hemostasis. CONCLUSIONS: Cardiac tamponade is a life-threatening condition that can sometimes be induced iatrogenically, resulting from percutaneous interventions. Despite limited evidence regarding this therapeutic strategy, in patients experiencing iatrogenic cardiac tamponade with hemodynamic instability and high surgical risk, the administration of intra-pericardial thrombin could be contemplated.
RESUMEN
INTRODUCTION: Transthyretin amyloid cardiomyopathy (ATTR-CM) is an underdiagnosed cause of AHF that benefits from a specific approach. The aim was to determine the prevalence of ATTR-CM among patients hospitalized for AHF. METHODS: A prospective study was conducted on consecutive patients aged 60 or older admitted for acute AHF without cardiogenic shock. RESULTS: The study included 103 patients, a total of 16 patients (15.5 %) were compatible with ATTR-CM. The ATTR-CM group showed a higher septal wall thickness (18.1 mm vs. 11.8 mm; P = 0.001), lower systolic excursion of the tricuspid annular plane (15 mm vs. 18.3 mm, P = 0.014), and S wave of the right ventricle (8 cm/s vs. 9.2 cm/s P=0.032). CONCLUSION: ATTR-CM is an underdiagnosed condition, there are some variables associated with its diagnosis. The coexistence with other comorbidities causing AHF, highlights the importance of considering screening for this cardiomyopathy in adults hospitalized for AHF.

INTRODUCTION: Safety and early clinical benefit make sodium-glucose cotransporter-2 inhibitor (SGLT2-i) therapy suitable for in-hospital initiation in patients with heart failure and reduced ejection fraction (HFrEF). Despite randomized controlled trials and guideline recommendations, they are underused, and clinical inertia may play a role. OBJECTIVES PRIMARY: To assess the impact of initiating SGLT-2i at discharge on 90-day prescription rates in patients with HFrEF during hospitalization for acute heart failure (AHF). Secondary: To evaluate the presence of independent factors associated with prescription, and to explore clinical outcomes at 90 days. METHODS: Retrospective analysis of a consecutive prospective single-center cohort. Adult patients hospitalized between January 2021 and September 2022 with a primary diagnosis of AHF and left ventricular ejection fraction (LVEF) <40% were included. The primary outcome was SGLT2-i prescription rate at 90 days, and the exploratory secondary endpoints was the composite of hospitalization or urgent visit for AHF or all-cause mortality at 90 days. RESULTS: 237 patients were included. Mean age was 76±11 years, and mean LVEF was 29±7%. In patients without contraindications, SGLT2 inhibitors (SGLT2-i) were prescribed during hospitalization in 52.3%. At 90 days, the SGLT2-i prescription rate was 94.2% in those with in-hospital initiation and 14.4% in those without. (p<0.001). Independent factor associated with inpatient prescription was lower LVEF, 0.83 (95% CI: 0.77-0.89) for each point. Patients with in-hospital SGLT2-i initiation showed a lower rate of the combined endpoint of all-cause death, HF rehospitalization, or unplanned HF visit at 90 days (44.4% versus 23.9%, p=0.005). CONCLUSIONS: In-hospital initiation of SGLT-2-i was associated with significantly higher prescription rates and lower prevalence in the secondary combined endpoint at 90 days. This study reflects the presence of medical inertia, particularly in patients with higher LVEF, and highlights the hospitalization period as an optimal time to start SGLT2-i.
