Electrocardiographic features and need for pacemaker in cardiac amyloidosis: Analysis of 58 cases.

Med Clin (Barc) 2022 Jan 21. Epub 2022 Jan 21.

Servicio de Cardiología, Hospital Universitario Reina Sofia, Córdoba, España; Instituto Maimónides de Investigación Biomédica de Córdoba, Universidad de Córdoba, Córdoba, España.

Aim: Amyloidosis is a disease in which amyloid fibrils can be deposited in different cardiac structures, and several electrocardiographic abnormalities can be produced by this phenomenon. The objective of this study was to describe the most common basal electrocardiographic alterations in patients diagnosed with cardiac amyloidosis (CA) and to determine if these abnormalities have an impact on the need of pacemaker.

Methods: This retrospective study included patients who had an established diagnosis of CA [light-chain cardiac amyloidosis (LA-CA) or transthyretin cardiac amyloidosis (TTR-CA)] between January 2013 and March 2021. Read More

Functional classification of left ventricular remodelling: prognostic relevance in myocardial infarction.

ESC Heart Fail 2022 Jan 22. Epub 2022 Jan 22.

Department of Cardiology, Heart and Lung Centre, Leiden University Medical Centre, Albinusdreef 2, Leiden, 2300 RC, The Netherlands.

Aims: The current definition of post ST-segment elevation myocardial infarction (STEMI) left ventricular (LV) remodelling is purely structural (LV dilatation) and does not consider LV function (ejection fraction, EF), even though it is known to be a predictor of long-term post-STEMI outcome. This study aimed to reclassify LV remodelling after STEMI by integrating LV dilatation and function (LVEF) and to investigate the prognostic implications.

Methods And Results: Data from an ongoing registry of STEMI patients who were treated with primary percutaneous coronary intervention (PCI) were retrospectively evaluated. Read More

Diagnostics (Basel) 2021 Dec 22;12(1). Epub 2021 Dec 22.

Unit for Screening Studies in Inherited Cardiovascular Diseases, National Institute of Cardiology, 04-628 Warsaw, Poland.

Titin truncating variants (tv) are known as the leading cause of inherited dilated cardiomyopathy (DCM). Nevertheless, it is unclear whether circulating cardiac biomarkers are helpful in detection and risk assessment. We sought to assess 1) early indicators of cardiotitinopathy including the serum biomarkers high-sensitivity cardiac troponin T (hs-cTnT) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) in clinically stable patients, and 2) predictors of outcome among tv carriers.

Atrial Functional Tricuspid Regurgitation as a Distinct Pathophysiological and Clinical Entity: No Idiopathic Tricuspid Regurgitation Anymore.

J Clin Med 2022 Jan 13;11(2). Epub 2022 Jan 13.

Department of Cardiology, Istituto Auxologico Italiano, IRCCS, 20145 Milan, Italy.

Functional tricuspid regurgitation (FTR) is a strong and independent predictor of patient morbidity and mortality if left untreated. The development of transcatheter procedures to either repair or replace the tricuspid valve (TV) has fueled the interest in the pathophysiology, severity assessment, and clinical consequences of FTR. FTR has been considered to be secondary to tricuspid annulus (TA) dilation and leaflet tethering, associated to right ventricular (RV) dilation and/or dysfunction (the "classical", ventricular form of FTR, V-FTR) for a long time.

The Thromboembolic Predictability of CHADS-VASc Scores Using Different Echocardiographic Criteria for Congestive Heart Failure in Korean Patients with Nonvalvular Atrial Fibrillation.

J Clin Med 2022 Jan 7;11(2). Epub 2022 Jan 7.

Division of Cardiology, Department of Internal Medicine, Gachon University Gil Medical Center, Incheon 21565, Korea.

The association between congestive heart failure (CHF) of the CHADS-VASc scores and thromboembolic (TE) events in patients with atrial fibrillation (AF) is a topic of debate due to conflicting results. As the importance of diastolic impairment in the occurrence of TE events is increasingly recognized, it is crucial to evaluate the predictive power of CHADS-VASc scores with C criterion integrating diastolic parameters. We analyzed 4200 Korean nonvalvular AF patients (71 years of age, 59% men) to compare multiple echocardiographic definitions of CHF. Read More

Plasma potassium concentration and cardiac repolarisation markers, T-T and T-T/QT, during and after exercise in healthy participants and in end-stage renal disease.

Eur J Appl Physiol 2022 Jan 20. Epub 2022 Jan 20.

Institute for Health and Sport, Victoria University, Melbourne, Australia.

Purpose: The cardiac T-wave peak-to-end interval (T) is thought to reflect dispersion in ventricular repolarisation, with abnormalities in T associated with increased risk of arrhythmia. Extracellular K modulates cardiac repolarisation, and since arterial plasma K concentration ([K]) rapidly increases during and declines following exercise, we investigated the relationship between [K] and T with exercise.

Methods: Serial ECGs (T, T/QT ratio) and [K] were obtained from 8 healthy, normokalaemic volunteers and 22 patients with end-stage renal disease (ESRD), at rest, during, and after exhaustive exercise. Read More

Post-ST-Segment-Elevation Myocardial Infarction Platelet Reactivity Is Associated With the Extent of Microvascular Obstruction and Infarct Size as Determined by Cardiac Magnetic Resonance Imaging.

J Am Heart Assoc 2022 Jan 19:e020973. Epub 2022 Jan 19.

Sheba Medical Center Lev Leviev Heart, and Vascular Center Tel Hashomer Israel.

Background Despite optimized medical management and techniques of primary percutaneous coronary intervention, a substantial proportion of patients with ST-segment-elevation myocardial infarction (STEMI) display significant microvascular damage. Thrombotic microvascular obstruction (MVO) has been implicated in the pathogenesis of microvascular and subsequent myocardial damage attributed to distal embolization and microvascular platelet plugging.

Terminal T-wave inversion predicts reperfusion tachyarrhythmias in STEMI.

J Electrocardiol 2022 Jan 5;71:28-31. Epub 2022 Jan 5.

Department of Cardiology, Clinical Sciences, Lund University, Lund, Sweden; Arrhythmia Clinic, Skåne University Hospital, 22185 Lund, Sweden.

Introduction: A reliable electrocardiographic predictor of ventricular fibrillation (VF) in patients with ST elevation myocardial infarction (STEMI) is lacking so far. Previous experimental/simulation study suggested a terminal T-wave inversion (TTWI) in ischemia-related ECG leads corresponding to anterior infarct localization as an independent predictor of reperfusion VF (rVF). This T-wave characteristic has never been tested as a rVF predictor in clinical settings. Read More
