Prognostic impact of iron deficiency in new-onset chronic heart failure: Danish Heart Failure Registry insights.

Aims: Iron deficiency (ID) is prevalent in chronic heart failure (HF) but lacks a consensus definition. This study evaluates the prevalence and the prognostic impact of ID using different criteria on all-cause and cardiovascular mortality, as well as first hospitalization for HF in patients with new-onset chronic HF.

Methods: In this nationwide registry-based cohort, we explored four definitions of ID: the current European Society of Cardiology (ESC) guidelines [ferritin <100 ng/mL or ferritin 100-299 ng/mL and transferrin saturation (TSAT) <20%], ferritin level <100 ng/mL, TSAT < 20% and serum iron ≤13 μmol/L.

Myocardial infarction with non-obstructive coronary arteries (MINOCA) is characterized by clinical evidence of myocardial infarction with normal or near-normal coronary arteries on angiography (less-than 50% stenosis). MINOCA is a group of heterogeneous diseases with different pathophysiologic mechanism which all can cause ischaemia. MINOCA is considered a "working diagnosis" after angiography until further evaluation regarding its underlying cause is made.

The association between Takotsubo cardiomyopathy and thyrotoxicosis: A systematic review.

Purpose: This study aims to review all published cases on the association between thyrotoxicosis and Takutsubo Syndrome by describing clinical characteristics, diagnostic work-up, treatment, and outcome.

Methods: We searched PubMed and Embase databases from inception to the 17th of February 2022 for case reports or series reporting the above-mentioned association. We extracted data on demographic characteristics, clinical features, diagnostic work-up, treatment, and clinical outcomes.

[Rapid and secure exclusion of myocardial infarctionwithout ST-segment elevation].

Rapid identification of acute myocardial infarction (MI) is important for the early initiation of evidence-based therapy. In the European Society of Cardiology (ESC) 0/1h-algorithm (also called early-rule-out algorithm) high-sentivity cardiac troponin is measured at admission and one hour later. By using assay-specific cut-off levels patients are triaged to three different groups; "rule-out", "observation" or "rule-in" of acute MI.

[Rational dosing of diuretics in the treatment of chronic heart failure with acute deterioration].

For decades, diuretics have been the cornerstone in the treatment of patients with chronic heart failure with reduced ejection fraction (HFrEF) presenting with congestion. However, evidence guiding the use of diuretics is generally lacking. Adequate dosing and evaluation of diuretic effect are important for treatment success.
