Background: In this multicenter prospective study, we explored the relationship between pulmonary artery pressure (PAP) at rest and in response to a 6-min walk test (6MWT) in ambulatory patients with heart failure (HF) with an implantable PAP sensor (CardioMEMS, Abbott).
Methods: Between 5/2019 and 2/2021, HF patients with a CardioMEMS sensor were recruited from seven sites. PAP was recorded in the supine and seated position at rest and in the seated position immediately post-exercise.

Heart failure and kidney failure are very common conditions, precipitating and exacerbating each other. Left ventricular assist devices (LVADs) represent a relatively new technology for treatment of advanced heart failure. Kidney dysfunction, if present, makes candidate selection for LVADs challenging and contributes to multiple complications while the patients are on an LVAD support.

Our objective was to study the utility of lactate measured at different points of time and lactate clearance in predicting the two study endpoints: successful ECMO weaning and hospital survival. Among 238 consecutive patients treated with ECMO, lactic acid was collected before initiating ECMO and then on days 1, 3, 5, and 10 while on ECMO.

Methods: The ESCAPE trial was utilized to identify the prognostic value of PAPI at different time points in patients hospitalized with acute systolic HF who received care assisted with central hemodynamic monitoring.
Introduction: Risk stratifying candidates for left ventricular assist device (LVAD) is challenging. While INTERMACS profiles provide some prognostic insights, there is an ongoing search for better tools. We studied pre-LVAD haemodynamic parameters in predicting post-LVAD mortality.

The association between inflammatory markers and the severity of acute pulmonary embolism (APE) has not been explored. We studied the association between two crude markers of inflammation, serum albumin, and red cell distribution width (RDW) and massive versus non-massive APE.

Sarcoidosis shows diverse clinical presentations, which may lead to a delayed diagnosis due to lack of a specific diagnostic test. Biomarkers of sarcoidosis duration have not been previously explored.

Methods: The Evaluation Study of Congestive Heart Failure and Pulmonary Artery Catheterization Effectiveness (ESCAPE) trial dataset was utilised to examine the characteristics and diuretic requirements of patients with ADHF with hyponatraemia or normonatraemia on admission.
Results: Patients with ADHF and admission hyponatraemia (n = 103, average Na 130.
Introduction: Current guidelines recommend at least 3 months of guideline-directed medical therapy (GDMT) for patients with a new onset of non-ischemic cardiomyopathy (NICM) and left bundle branch block (LBBB) prior to cardiac resynchronization therapy (CRT). For patients who do not receive optimal GDMT, response to CRT is unknown.
Methods: Patients with NICM and LBBB with QRS ≥ 120 ms were identified among all patients who underwent CRT.
Introduction: The prognostic effect of the direction of change in sodium (Na) level from admission to subsequent check in patients with acute heart failure (HF) has not been previously explored.
Methods: The ESCAPE trial data was utilized to study whether the rise of 1 follow-up Na (at day 3) relative to admission (among patients with admission hyponatremia) is associated with favorable outcomes. The study endpoints were all-cause rehospitalization and a composite of death, rehospitalization and cardiac transplant, both up to 6-month after discharge.

Ketogenic diet is being increasingly utilized in recent decades because of its success as an effective tool for short and intermediate-term weight loss. Promoting physiological ketosis from a drastically low carbohydrate diet is the fundamental basis for this diet regime. Though debated, these diets have been demonstrated to be effective, at least in the short- to medium terms, to manage excess weight, hyperlipidemia, and other cardiovascular risk factors.

The pathogenesis of pulmonary fibrosis in sarcoidosis is not known. We hypothesized that higher levels of circulatory growth factors are present in early stages of pulmonary sarcoidosis and may be associated with pulmonary fibrosis. Age and sex-matched subjects with sarcoidosis stage 0-1 (n=18), stage 4-5 (n=13) and healthy controls (n=5) had their serum TGF-β1, FGF, and VEGF levels measured as well as their gene expressions determined in peripheral blood mononuclear cells.

Methods: We retrospectively reviewed data of 552 consecutive adults with computed tomography pulmonary angiogram-confirmed APE to determine the correlates and outcome of the occurrence of syncope at the time of presentation.
Results: Among 552 subjects with APE (mean age 54years, 47% men), syncope occurred in 12.
Introduction: While the optimal care of patients with massive pulmonary embolism (PE) is unclear, the general goal of therapy is to rapidly correct the physiologic derangements propagated by obstructive clot. Extracorporeal membrane oxygenation (ECMO) in this setting is promising, however the paucity of data limits its routine use. Our institution expanded the role of ECMO as an advanced therapy option in the initial management of massive PE.

We explored the predictive utility of hyponatremia at the time of hospital discharge among HF patients with normal admission sodium (Na). Characteristics and outcomes of HF patients enrolled in the Evaluation Study of Congestive Heart Failure and Pulmonary Artery Catheterization Effectiveness trial, who had normal Na on admission, were compared between those who were hyponatremic (Na <135 meq/L) or normonatremic on discharge.
