For decades, nurses have monitored and titrated medications based on cardiac output. In the past, this was almost exclusively done through the use of an invasive pulmonary artery catheter. However, there are inherent patient risks to using a pulmonary artery catheter, and trends have shown a decreased use of this method. Advances in technology have brought about various noninvasive and minimally invasive methods to monitor cardiac output including pulse contour analysis, finger cuff technology, thoracic bioimpedance and bioreactance, and endotracheal electrical bioimpedance. A review of current noninvasive and minimally invasive methods to monitor cardiac output, and nursing considerations are discussed.

Sepsis-induced myocardial dysfunction (SIMD) involves reversible myocardial dysfunction. The use of inotropes can restore adequate cardiac output and tissue perfusion, but conventional inotropes, such as dobutamine and adrenaline, have limited efficacy in such situations. Levosimendan is a novel inotrope that acts in a catecholamine-independent manner.

Background: Insulin resistance (IR) plays a pivotal role in the interplay between metabolic disorders and heart failure with preserved ejection fraction (HFpEF). Various non-insulin-based indices emerge as reliable surrogate markers for assessing IR, including the triglyceride-glucose (TyG) index, the TyG index with body mass index (TyG-BMI), atherogenic index of plasma (AIP), and the metabolic score for insulin resistance (METS-IR). However, the ability of different IR indices to predict outcome in HFpEF patients has not been extensively explored.

Mean circulatory filling pressure, venous return curve, and Guyton's graphical analysis are basic concepts in cardiovascular physiology. However, some medical students may not know how to view and interpret or understand them adequately. To deepen students' understanding of the graphical analysis, in place of having to perform live animal experiments, we developed an interactive cardiovascular simulator, as a self-learning tool, as a web application.

Aims: Exercise testing remains underused in patients with aortic stenosis (AS), partly due to concerns about an exercise-induced drop in systolic blood pressure (SBP). We aimed to study the SBP response to exercise in patients with severe symptomatic AS prior to surgery and 1 year postoperatively.
Methods: Patients scheduled for aortic valve replacement due to severe symptomatic AS were enrolled at a single centre in a prospective observational cohort study.

Background: Extracorporeal membrane oxygenation (ECMO) can act as a bridge to recovery in both pre-and postoperative patients with transposition of the great arteries (TGA). However, literature on its use in these patients is scarce.
Methods: Retrospective single-centre cohort study encompassing all TGA patients who received ECMO between January 2009 and March 2024.
