Timing of invasive coronary angiography, management, and in-hospital outcomes among patients with non-ST-segment elevation myocardial infarction: A comprehensive nationwide analysis.

Background: The impact of timing of invasive coronary angiography (ICA) and management strategies on in-hospital outcomes among unselected all-comers with non-ST-segment elevation myocardial infarction (NSTEMI) presents an equipoise in clinical practice.

Methods: Patients with NSTEMI from the US NIS database during 2016 to 2021 were included in the analysis. In-hospital outcomes were examined according to the timing of ICA - early (<24 h), intermediate (24-72 h), and delayed (>72 h).

Pathophysiology of Congestion in Heart Failure: A Contemporary Review.

Acutely decompensated heart failure is one of the leading causes of hospitalisation worldwide, with a significant majority of these cases attributed to congestion. Although congestion is commonly mistaken for volume overload, evidence suggests that decompensation can occur without significant water accumulation, being attributed to volume redistribution. Yet, the distinction between intravascular and extravascular congestion in heart failure often blurs, as patients frequently exhibit overlapping features of both, and as patients may transition between phenotypes over time.
