Ventricular Fibrillation and Tachycardia Detection Using Features Derived from Topological Data Analysis

2022

A rapid and accurate detection of ventricular arrhythmias is essential to take appropriate therapeutic actions when cardiac arrhythmias occur. Furthermore, the accurate discrimination between arrhythmias is also important, provided that the required shocking therapy would not be the same. In this work, the main novelty is the use of the mathematical method known as Topological Data Analysis (TDA) to generate new types of features which can contribute to the improvement of the detection and classification performance of cardiac arrhythmias such as Ventricular Fibrillation (VF) and Ventricular Tachycardia (VT). The electrocardiographic (ECG) signals used for this evaluation were obtained from…

Late gadolinium enhancement-cardiovascular magnetic resonance identifies coronary artery disease as the aetiology of left ventricular dysfunction in …

2009

Aims We evaluated the ability of late gadolinium enhancement (LGE) using cardiovascular magnetic resonance (CMR) to identify acute new-onset heart failure (HF) with left ventricular systolic dysfunction (LVSD), whether or not in relation to underlying coronary artery disease (CAD), in patients with no clinical evidence of associated ischaemic cardiomyopathy. Methods and results Hundred consecutive patients admitted with acute new-onset decompensated HF and EF ,40%, with no clinical or electrocardiographic data suggestive of CAD. The patients were classified according to the presence or absence of significant CAD (stenosis � 70% in at least one major vessel). Twenty-one patients (21%) had si…

Role of Cardiac Magnetic Resonance Imaging in the Detection of Cardiac Amyloidosis

2010

Objectives Our aim was to evaluate the role and mechanism of late gadolinium enhancement (LGE) cardiac magnetic resonance (CMR) in identifying cardiac amyloidosis (CA) and to investigate associations between LGE and clinical, morphologic, functional, and biochemical features. Background CA can be challenging to diagnose by echocardiography. Recent studies have demonstrated an emerging role for LGE-CMR. Methods LGE-CMR was performed in 120 patients with amyloidosis. Cardiac histology was available in 35 patients. The remaining 85 patients were divided into those with and without echocardiographic evidence of CA. Results Of the 35 patients with histologically verified CA, abnormal LGE was pre…

Physical Activity : Absolute Intensity vs. Relative-to-Fitness-Level Volumes

2017

Purpose: This study aimed to investigate in a real-life setting how moderate- and vigorous-intensity physical activity (PA) volumes differ according to absolute intensity recommendation and relative to individual fitness level by sex, age, and body mass index. Methods: A total of 23,224 Finnish employees (10,201 men and 13,023 women; ages 18–65 yr; body mass index = 18.5–40.0 kg·m−2) participated in heart rate recording for 2+ d. We used heart rate and its variability, respiration rate, and on/off response information from R-R interval data calibrated by participant characteristics to objectively determine daily PA volume, as follows: daily minutes of absolute moderate (3–<6 METs) and vigor…

Clinical Predictors of Immunotolerance in Heart Transplantation

2010

Abstract Background and Aim The drugs routinely administered to prevent rejection often cause lethal side effects. Tolerant patients, therefore, should be identified to minimize these problems. The aim of this analysis was to identify clinical variables that may be associated with tolerance. Methods We recruited 522 heart transplants (HT), excluding combined procedures, retransplantations, pediatric recipients, and subjects who died in the first year to obtain a cohort of 375 patients. Two groups were distinguished by the presence of echocardiographic, clinical, or pathological evidence of rejection in the first year (15 echocardiograms and 10 protocol biopsies per patient); 99 tolerant pat…

Update I. A systematic review on the efficacy and safety of chloroquine/hydroxychloroquine for COVID-19

2020

Purpose To assess efficacy and safety of chloroquine (CQ)/hydroxychloroquine (HCQ) for treatment or prophylaxis of COVID-19 in adult humans. Materials and methods MEDLINE, PubMed, EMBASE and two pre-print repositories (bioRxiv, medRxiv) were searched from inception to 8th June 2020 for RCTs and nonrandomized studies (retrospective and prospective, including single-arm, studies) addressing the use of CQ/HCQ in any dose or combination for COVID-19. Results Thirty-two studies were included (6 RCTs, 26 nonrandomized, 29,192 participants). Two RCTs had high risk, two ‘some concerns’ and two low risk of bias (Rob2). Among nonrandomized studies with comparators, nine had high risk and five moderat…

Korelācija starp ehokardiogrammu un EKG atradni slimniekiem ar kreisā kambara hipertorfiju

2018

KOPSAVILKUMS Pamatojums Kreisā kambara hipertrofijai tiek pievērsta uzmanība globālā līmenī. Kreisā kambara hipertrofijas esamība un tās pakāpes novērtēšana ir neatņemama sastāvdaļa ikdienā veiktiem mērījumiem kardioloģijā. Gan ehokardiogrāfija (EhoKG), gan elektrokardiogrāfija (EKG) ir labi zināmas metodes kreisā kamabara hipertrofijas un ar to saistītā riska novērtēšanai. Kreisā kambara hipertrofija tiek uzskatīta par neatkarīgu kardiovaskulārās mirstības un saslimstības riska faktoru. Mērķis Noteikt kreisā kambara hipertrofijas pazīmes, izmantojot elektrokardiogrāfijas un ehokardiogrāfijas metodes, un noskaidrot korelāciju starp kreisā kambara hipertrofijas pazīmēm EKG un EhoKG, kā arī n…
