Background: During sepsis, heart rate (HR) reduction could be a therapeutic target, but identification of responders (non-compensatory tachycardia) and non-responders (compensatory for ‘fixed’ stroke volume [SV]) is challenging. We tested the ability of the difference between systolic and dicrotic pressure (SDPdifference), which reflects the coupling between myocardial contractility and a given afterload, in discriminating the origin of tachycardia.

The differential outcomes across the age spectrum of transcatheter aortic valve implantation (TAVI) recipients are still debated. Aim of the study was to evaluate the clinical outcomes of oldest-old patients undergoing TAVI in the large “Registro Italiano GISE sull'impianto di Valvola Aortica Percutanea (RISPEVA)” registry. A total of 3,507 patients were stratified according to age: 1,381 were ≥85 years, 2,126 were <85 years. Primary endpoints were death at 30-days and complete follow-up (FU) (medium 368 days).

Background: In-hospital course of patients with Takotsubo syndrome (TS) is quite heterogeneous and life-threatening complications are not uncommon in the acute phase. The role of heart rate (HR) as a predictor of prognosis has not been sufficiently investigated in this setting. The study aims to assess the impact of HR at presentation on in-hospital course of patients with TS. Methods: The study population included 221 patients with TS enrolled in a multicentric registry. HR at admission was evaluated on the first electrocardiogram.

We construct classical solutions to the nonlinear Maxwell system
with periodic boundary conditions which blow up in H(curl).
A similar result is shown on the full space. Our construction is based on an analysis of a shock wave in one space dimension.

Cardiogenic shock (CS) is a cardiac emergency often leading to multiple organ failure and death. Assessing organ dysfunction and appropriate risk stratification are central for the optimal management of these patients. The purpose of this study was to assess the prevalence of abnormal liver function tests (LFTs), as well as early changes of LFTs and their impact on outcome in CS. We measured LFTs in 178 patients in CS from serial blood samples taken at 0 hours, 12 hours, and 24 hours.

Introduction: Ischemic colitis (IC) accounts for more of the half of total diagnosis of gastrointestinal ischemia. It is a challenging condition due to non-specificity of the symptoms at onset, inconstant behaviour and a wide range of clinical gravity with a different therapeutic approach. A classification of IC into gangrenous, stricturing and transient forms can be considered.
