Purpose: To analyze the accuracy of defining characteristics of the NANDA International nursing diagnosis, fatigue (00093), in patients with heart failure.
Methods: A cross-sectional study on the diagnostic accuracy of the defining characteristics of the nursing diagnosis. The sample consisted of 96 patients with heart failure in treatment in a public hospital. The latent class analysis method was used to test the accuracy measurements and estimate the prevalence of the diagnosis. The study was approved by the Research Ethics Committee of the Federal University of Rio Grande do Norte.
Results: The prevalence of the fatigue nursing diagnosis was 42.54%. Increased physical symptoms (0.9988) and tiredness (0.9988) were the sensitive defining characteristics. Disinterested in surroundings (0.9999) was the specific defining characteristics.
Conclusions: A set of three defining characteristics of the nursing diagnosis of fatigue was accurate in patients with heart failure. Thus, this set can be used by nurses to confirm nursing diagnosis fatigue in patients with heart failure.
Implications For Nursing Practice: This research contributes by providing accurate defining characteristics of fatigue in patients with heart failure. Thus, nurses should recognize the nursing diagnosis of fatigue in patients with heart failure through accurate defining characteristics and propose rapid and effective nursing interventions that have positive health results.

Department of Cardiology, Ippokrateio University Hospital, Athens, Greece.
Introduction/objective: Emotional, mental, or psychological distress, defined as increased symptoms of depression, anxiety, and/or stress, is common in patients with chronic diseases, such as cardiovascular (CV) disease (CVD).
Methods: Literature was reviewed regarding data from studies and meta-analyses examining the impact of emotional stress on the occurrence and outcome of several CVDs (coronary disease, heart failure, hypertension, arrhythmias, stroke). These influences' pathophysiology and clinical spectrum are detailed, tabulated, and pictorially illustrated.

Aims: This study was to explore the relationship between plasma exosomes and Acute myocardial infarction (AMI).
Background: Acute myocardial infarction (AMI) is one of the most common cardiovascular complications. Recent studies have shown that exosomes play a crucial role in the development and progression of cardiovascular diseases.
Effect of Finerenone in Cardiovascular and Renal Outcomes: A Systematic Review and Meta-analysis.

Department of Cardiovascular Science, Ascension St, Thomas Hospital, University of Tennessee Health Science Center, Nashville, TN, USA.
Purpose: Heart failure (HF) management is well-defined for reduced ejection fraction (HFrEF) but less so for mildly reduced (HFmrEF) or preserved ejection fraction (HFpEF). This meta-analysis evaluates the impact of Finerenone, a nonsteroidal mineralocorticoid receptor antagonist, on cardiovascular and renal outcomes in these patient populations.
Methods: A systematic search in PubMed and Embase identified randomized controlled trials (RCTs) on Finerenone's cardiovascular and renal effects.
Novel Selective Cardiac Myosin-Targeted Inhibitors Alleviate Myocardial Ischaemia-Reperfusion Injury.

The Hatter Cardiovascular Institute, University College London, 67 Chenies Mews, London, WC1E 6HX, UK.
Purpose: Reperfusion of the ischaemic heart is essential to limit myocardial infarction. However, reperfusion can cause cardiomyocyte hypercontracture. Recently, cardiac myosin-targeted inhibitors (CMIs), such as Mavacamten (MYK-461) and Aficamten (CK-274), have been developed to treat patients with cardiac hypercontractility.

There are differing opinions in the literature regarding the cardiovascular safety of long-term methylphenidate use. Studies suggest that the drug may increase the risk of hypertension, myocardial infarction, ventricular arrhythmia, sudden cardiac death, cardiomyopathy, heart failure (HF), pulmonary hypertension, and stroke.
