    Smart CardioWatch System for Patients with Cardiovascular Diseases Who Live Alone

    Raisa Nazir Ahmed Kazi1,*, Manjur Kolhar2, Faiza Rizwan2

    CMC-Computers, Materials & Continua, Vol.66, No.2, pp. 1237-1250, 2021, DOI:10.32604/cmc.2020.012707 - 26 November 2020

    Abstract The widespread use of smartwatches has increased their specific and complementary activities in the health sector for patient’s prognosis. In this study, we propose a framework referred to as smart forecasting CardioWatch (SCW) to measure the heart-rate variation (HRV) for patients with myocardial infarction (MI) who live alone or are outside their homes. In this study, HRV is used as a vital alarming sign for patients with MI. The performance of the proposed framework is measured using machine learning and deep learning techniques, namely, support vector machine, logistic regression, and decision-tree classification techniques.

    Coralie Katharina Dicks1, Gerhard-Paul Diller1, Kristina Wasmer2, Paul C. Helm3,4, Ulrike M. M. Bauer3,4, Helmut Baumgartner1, Stefan Orwat1,#, Alicia Jeanette Fischer1,#,*

    Congenital Heart Disease, Vol.15, No.2, pp. 117-125, 2020, DOI:10.32604/CHD.2020.011520 - 23 June 2020

    Abstract Background: Sudden cardiac death is a leading cause of death in patients with congenital heart disease (CHD). Risk stratification for implantable cardioverter defibrillators (ICD) remains difficult due to limited data about use and outcome of device therapy in CHD patients in larger community-based cohorts. Methods and results: Out of a dataset with more than 50,000 patients registered at the German National Register for Congenital Heart Defects, 109 patients (median age 35.5; IQR 23.75–46.00), 68 (62%) male) with an ICD were identified and were retrospectively analyzed. Although the number of implantations increased steadily throughout the investigated time interval… More >

    Behavioral Feature and Correlative Detection of Multiple Types of Node in the Internet of Vehicles

    Pengshou Xie1, Guoqiang Ma1, *, Tao Feng1, Yan Yan1, 2, Xueming Han1

    CMC-Computers, Materials & Continua, Vol.64, No.2, pp. 1127-1137, 2020, DOI:10.32604/cmc.2020.09695 - 10 June 2020

    Abstract Undoubtedly, uncooperative or malicious nodes threaten the safety of Internet of Vehicles (IoV) by destroying routing or data. To this end, some researchers have designed some node detection mechanisms and trust calculating algorithms based on some different feature parameters of IoV such as communication, data, energy, etc., to detect and evaluate vehicle nodes. However, it is difficult to effectively assess the trust level of a vehicle node only by message forwarding, data consistency, and energy sufficiency. In order to resolve these problems, a novel mechanism and a new trust calculating model is proposed in this… More >

    Cardiovascular risk factors in adults with coarctation of the aorta

    Maria Fedchenko, Zacharias Mandalenakis, Helena Dellborg, Görel Hultsberg‐Olsson, Anna Björk, Peter Eriksson, Mikael Dellborg

    Congenital Heart Disease, Vol.14, No.4, pp. 549-558, 2019, DOI:10.1111/chd.12785

    Abstract Background: The aging patient with adult congenital heart disease (ACHD) faces the risk of developing atherosclerotic disease. Patients with coarctation of the aorta (CoA) are especially vulnerable because of an inherent high risk of developing hy‐ pertension. However, data on the prevalence of other cardiovascular risk factors are scarce. Therefore, this study aimed to describe the prevalence of traditional cardio‐ vascular risk factors (diabetes, hypertension, hyperlipidemia, smoking, obesity, and sedentary lifestyle) in adult patients with CoA.
    Methods: Patients with CoA who were registered at the ACHD clinic in Gothenburg were asked to participate in a comprehensive cardiovascular… More >

    Congenital Heart Disease, Vol.14, No.4, pp. 525-533, 2019, DOI:10.1111/chd.12767

    Abstract Objective: Sudden cardiac death is common in the adult congenital heart disease (ACHD) population. Knowledge and experience about the use of implantable cardio‐ verter defibrillators (ICD) in ACHD patients is very limited. We aimed to characterize a cohort of patients with ACHD and ICDs.
    Design: Thirty consecutive ACHD patients submitted to an ICD implantation in a single tertiary center were evaluated. Data on baseline clinical features, heart defect, indication for ICD, type of device, appropriate therapies, ICD‐related complication, and mortality during follow‐up were collected.
    Results: Of the 30 patients, 56.7% received appropriate therapies due to ventricular tachycardia (VT)… More >

    Pharmacologic stress cardiovascular magnetic resonance in the pediatric population: A review of the literature, proposed protocol, and two examples in patients with Kawasaki disease

    Munes Fares1, Paul J. Critser2, Maria J. Arruda1, Carolyn M. Wilhelm1, Mantosh S. Rattan3, Sean M. Lang2,4, Tarek Alsaied2,4

    Congenital Heart Disease, Vol.14, No.6, pp. 1166-1175, 2019, DOI:10.1111/chd.12840

    Abstract Pharmacologic stress cardiovascular magnetic resonance (PSCMR) is a wellestablished and reliable diagnostic tool for evaluation of coronary artery disease in the adult population. Stress imaging overall and PSCMR in particular is less utilized in the pediatric population with limited reported data. In this review, we highlight the potential use of PSCMR in specific pediatric cohorts with congenital and acquired heart disease, and we review the reported experience. A suggested protocol is presented in addition to two case examples of patients with Kawasaki disease where PSCMR aided decision making. More >

    Improvement in ventricular function with rhythm control of atrial arrhythmias may delay the need for atrioventricular valve surgery in adults with congenital heart disease

    Benjamin Zielonka1, Yuli Y. Kim2,3, Gregory E. Supple2, Sara L. Partington2,3, Emily S. Ruckdeschel2,3, Francis E. Marchlinski2, David S. Frankel2

    Congenital Heart Disease, Vol.14, No.6, pp. 931-938, 2019, DOI:10.1111/chd.12833

    Abstract Objective: Atrial arrhythmias and atrioventricular valve regurgitation (AVVR) are common causes of morbidity among adults with congenital heart disease (ACHD). The impact of rhythm control on AVVR in this population is unknown. We sought to determine whether a rhythm control strategy is associated with greater freedom from AV valve surgery than a rate control strategy.
    Design: Patients evaluated by both ACHD and electrophysiology specialists at a single academic center were screened for atrial arrhythmias and at least moderate‐severe AVVR. Clinical and electrographic data were abstracted. All echocardiograms were in‐ terpreted by a single echocardiographer blinded to treatment… More >

    Arteriovenous fistula creation for hypoxia after single ventricle palliation: A single‐institution experience and literature review

    Andrew D. Spearman1, Steven J. Kindel1, Ronald K. Woods2, Salil Ginde1,3

    Congenital Heart Disease, Vol.14, No.6, pp. 1199-1206, 2019, DOI:10.1111/chd.12828

    Abstract Background: Hypoxia is a common and sometimes severe morbidity of single ven‐ tricle congenital heart disease (CHD). Creation of an arteriovenous fistula (AVF) is occasionally performed for patients after superior or total cavopulmonary connec‐ tion (SCPC or TCPC) in an attempt to improve oxygen saturations. Despite previ‐ ous reports, AVF creation is a rare palliation with inadequately defined benefits and risks. We sought to determine changes in peripheral oxygen saturation (SpO2) and risk of adverse event after AVF creation in children with single ventricle CHD at our institution.
    Methods: We conducted a retrospective chart review of patients… More >
