Electrophysiological effects of 5-hydroxytryptamine on isolated human atrial myocytes, and the influence of chronic beta-adrenoceptor blockade [PDF]

, 2003
<b>1.</b> 5-Hydroxytryptamine (5-HT) has been postulated to play a proarrhythmic role in the human atria via stimulation of 5-HT₄ receptors.

Association of COPD with adverse outcomes in heart failure patients with preserved ejection fraction

ESC Heart Failure, Volume 12, Issue 2, Page 799-808, April 2025.
Abstract We performed a systematic review and meta‐analysis to detect the impact of chronic obstructive pulmonary disease (COPD) on the prognosis of heart failure patients with preserved ejection fraction (HFpEF). We systematically screened eligible literature from three electronic databases, PubMed, EMBASE and Cochrane Library, up to April 2023.

Transthyretin amyloid cardiomyopathy: Literature review and red‐flag symptom clusters for each cardiology specialty

ESC Heart Failure, Volume 12, Issue 2, Page 955-967, April 2025.
Abstract Wild‐type transthyretin amyloid cardiomyopathy (ATTRwt‐CM) is a progressive and infiltrative cardiac disorder that may cause fatal consequences if left untreated. The estimated survival time from diagnosis is approximately 3–6 years. Because of the non‐specificity of initial symptom manifestation and insufficient awareness among treating ...

Prognostic role of high‐sensitivity cardiac troponin T in patients with cardiac sarcoidosis: insights from ILLUMINATE‐CS

ESC Heart Failure, Volume 12, Issue 2, Page 869-878, April 2025.
Abstract Aims The prognostic role of high‐sensitivity cardiac troponin T (hs‐cTnT) as a biomarker in patients with cardiac sarcoidosis (CS) has yet to be fully determined, especially when compared with B‐type natriuretic peptide (BNP). Methods and Results In this post‐hoc analysis of the ILLUMINATE‐CS (ILLUstration of the Management and prognosIs of ...

The G protein-gated potassium current I(K,ACh) is constitutively active in patients with chronic atrial fibrillation [PDF]

, 2005
Background— The molecular mechanism of increased background inward rectifier current (IK1) in atrial fibrillation (AF) is not fully understood. We tested whether constitutively active acetylcholine (ACh)-activated IK,ACh contributes to enhanced basal ...

24. Entrainment of wide complex tachycardia by atrial stimulation is highly accurate and can rapidly elucidate the tachycardia mechanism through analysis of entrainment response

Journal of the Saudi Heart Association, 2015
Although the diagnosis of wide-complex tachycardia (WCT) in the Electrophysiology Laboratory is usually straightforward, occasionally a WCT with 1:1 AV relationship can pose a diagnostic challenge.

The effects of sodium–glucose cotransporter 2 inhibitors on the ‘forgotten’ right ventricle

ESC Heart Failure, Volume 12, Issue 2, Page 1045-1058, April 2025.
Abstract With the progress in diagnosis, treatment and imaging techniques, there is a growing recognition that impaired right ventricular (RV) function profoundly affects the prognosis of patients with heart failure (HF), irrespective of their left ventricular ejection fraction (LVEF).
