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 ...

Respiratory sinus arrhythmia in Chagas disease [PDF]
Autonomic Neuroscience, 2014 We applied the respiratory sinus arrhythmia (RSA) quantification algorithm to 24-hour ECG recordings of Chagas disease (ChD) patients with (G1, n=148) and without left ventricular dysfunction (LVD) (G2, n=33), and in control subjects (G0, n=28). Both ChD groups displayed a reduced RSA index; G1=299 (144-812); G2=335 (162-667), p=0.011, which was ...

Interventional therapies for chronic heart failure: An overview of recent developments
ESC Heart Failure, Volume 12, Issue 2, Page 1081-1094, April 2025.Abstract Heart failure (HF), the final manifestation of most cardiovascular diseases, has become a major global health concern, affecting millions of individuals. Despite basic drug treatments, patients present with high morbidity and mortality rates. However, recent advancements in interventional therapy have shown promising results in improving the ...

Respiratory sinus arrhythmia: a frequency dependent phenomenon
, 1964 An examination of respiratory sinus arrhythmia is presented. Sinusoidal breathing was varied over a wide frequency range and the amplitude and phase of the accompanying fluctuations of heart rate were observed.

Considerations for drug trials in hypertrophic cardiomyopathy
ESC Heart Failure, Volume 12, Issue 2, Page 1095-1112, April 2025.Abstract Hypertrophic cardiomyopathy (HCM) is a heterogeneous condition with potentially serious manifestations. Management has traditionally comprised therapies to palliate symptoms and implantable cardioverter‐defibrillators to prevent sudden cardiac death. The need for disease‐modifying therapies has been recognized for decades.

Variation of respiratory sinus arrhythmia with age
, 1976 Respiratory sinus arrhythmia was measured on 24 male subjects whose agesranged from 21 to 65 yr, using a technique in which respiration was coupledto heart rate, so that there were 6 heartbeats per inspiration and 6 heartbeats per expiration.

ESC Heart Failure, Volume 12, Issue 2, Page 1316-1325, April 2025.Abstract Objective This study aimed to evaluate the utility of left atrial volume and function in uraemic patients using four‐dimensional automatic left atrial quantification (4D auto LAQ) technology. Methods Thirty‐four undialysed uraemic patients (U‐ND group), 60 dialysed uraemic patients (U‐D group), and 32 healthy volunteers (N group) were enrolled
