Diagnosis of Mitral Valve Prolapse: Much More than Simple Prolapse. Multimodality Approach to Risk Stratification and Therapeutic Management.

J Clin Med 2022 Jan 17;11(2). Epub 2022 Jan 17.

Heart Centre, King Faisal Specialist Hospital & Research Centre, Riyadh 11211, Saudi Arabia.

Mitral valve prolapse (MVP) is the most common valvular disease with a prevalence of 2%. It has generally a benign course; however, recent findings suggested an association between MVP and complex arrhythmias and eventually cardiac arrest and for this reason, it is also called arrhythmogenic MVP. Subjects who experience this complication are in general young women, with thickened mitral leaflets or bileaflet prolapse not necessarily associated with severe mitral regurgitation (MR). Read More

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

The utility of SYNTAX score predictability by electrocardiogram parameters in patients with unstable angina.

BMC Cardiovasc Disord 2022 Jan 12;22(1). Epub 2022 Jan 12.

Shiraz University of Medical Sciences, Shiraz, Iran.

Background: SYNTAX score is one of the risk assessment systems to predict cardiac events in acute coronary syndrome patients. Despite the large number of SYNTAX score benefits, invasive methods such as coronary angiography are necessary to perform the scoring. We hypothesized that ECG parameters could predict the SYNTAX score in unstable angina patients. Read More

The Female Athlete's Heart: Overview and Management of Cardiovascular Diseases.

Eur Cardiol 2021 Feb 2;16:e47. Epub 2021 Dec 2.

National Heart and Lung Institute, Imperial College London UK.

The number of female athletes taking part in elite and amateur sport is ever increasing. In contrast with male athletes, few studies have focused on cardiovascular adaptations to exercise in women, the effects of lifelong exercise on heart muscle and electrical tissue, the risk of exerciserelated sudden cardiac death and the management of cardiovascular disease. Women have a lower prevalence of large QRS complexes, repolarisation changes including inferior and lateral T-wave inversion, and cardiac dimensions exceeding predicted limits compared with men.

Catecholamines are key modulators of ventricular repolarization patterns in the ball python (Python regius).

J Gen Physiol 2022 Feb 15;154(2). Epub 2021 Dec 15.

University of Amsterdam, Amsterdam UMC, Department of Medical Biology, Amsterdam Cardiovascular Sciences, Amsterdam, The Netherlands.

Ectothermic vertebrates experience daily changes in body temperature, and anecdotal observations suggest these changes affect ventricular repolarization such that the T-wave in the ECG changes polarity. Mammals, in contrast, can maintain stable body temperatures, and their ventricular repolarization is strongly modulated by changes in heart rate and by sympathetic nervous system activity. The aim of this study was to assess the role of body temperature, heart rate, and circulating catecholamines on local repolarization gradients in the ectothermic ball python (Python regius).

Beware of regression of electrocardiographic abnormalities on detraining - It may not always mean 'athlete's heart'.

Rev Port Cardiol (Engl Ed) 2021 Oct;40(10):801.e1-801.e6

Departamento de Cardiologia, Hospital dos Lusíadas, Nova Medical School, Lisboa, Portugal.

Hypertrophic cardiomyopathy is one of the main causes of sudden cardiac death in young athletes. Differentiating between this pathological condition and 'athlete's heart' can be quite challenging, warranting a thorough clinical and imaging assessment. Clinicians often rely on detraining-induced attenuation of electrocardiographic and echocardiographic findings as a means of distinguishing between pathological and physiological cardiac remodeling.

Case Report: Abnormal ECG and Pantalgia in a Patient With Guillain-Barré Syndrome.

Front Cardiovasc Med 2021 6;8:742740. Epub 2021 Oct 6.

Department of Cardiovascular Surgery, The First Affiliated Hospital of Xi'an Jiaotong University, Xi'an, China.

Guillain-Barré syndrome (GBS) is an acute immune-mediated disorder in the peripheral nervous system (PNS) characterized by symmetrical limb weakness, sensory disturbances, and clinically absent or decreased reflexes. Pantalgia and dysautonomia, including cardiovascular abnormalities, are common findings in the spectrum of GBS. It is usually challenging to distinguish GBS-related electrocardiogram (ECG) abnormities and chest pain from acute coronary syndrome (ACS) in patients with GBS due to the similar clinical symptom and ECG characteristics.

Prehospital ECG with ST-depression and T-wave inversion are associated with new onset heart failure in individuals transported by ambulance for suspected acute coronary syndrome.

J Electrocardiol 2021 Nov-Dec;69S:23-28. Epub 2021 Aug 13.

University of North Carolina at Chapel Hill, Chapel Hill, NC, USA.

Background: Prehospital electrocardiogram(s) (ECG) can improve early detection of acute coronary syndrome (ST-segment elevation myocardial infarction [STEMI], non-STEMI, and unstable angina) and inform prehospital activation of cardiac catheterization lab; thus, reducing total ischemic time and improving patient outcomes. Less is known, however, about the association of prehospital ECG ischemic findings and long term adverse clinical events. With this in mind, this study was designed to examine the: 1) frequency of prehospital ECGs for acute myocardial ischemia (ST-elevation, ST-depression, and/or T-wave inversion); and, 2) whether any of these specific ECG features are associated with adverse clinical events within 30 day of initial presentation to the emergency department (ED).

Arrhythmic mitral valve prolapse: Diagnostic parameters for high-risk patients: A systematic review and meta-analysis.

Pacing Clin Electrophysiol 2021 Oct 24;44(10):1746-1755. Epub 2021 Aug 24.

Ain Shams University Faculty of Medicine, Neurology; California Institute of Behavioral Neurosciences & Psychology, Neurology, Cairo, Egypt.

Background: Although frequently considered a benign condition, new evidence has shown that mitral valve prolapse (MVP) is associated with complex ventricular arrhythmias (VAs) and sudden cardiac death (SCD). Therefore, we conducted a systematic review and meta-analysis of the relevant studies to investigate the parameters that could identify MVP patients at higher risk of experiencing complex VAs.

Method: We performed a systematic literature search of PubMed for potential studies between January 2010 and January 2021. Read More
