South Asian Arrhythmogenic Cardiomyopathy Registry
Arrhythmogenic Right Ventricular CardiomyopathyArrhythmogenic Right Ventricular Dysplasia4 moreArrhythmogenic Cardiomyopathy (ACM) is increasingly identified as an important cause of cardiac morbidity and mortality, especially of SCD, in a younger population. Although there are no epidemiological data available, the investigators' experience is that in the North Indian region, ACM is rare outside our regions. ACM is also an understudied cardiac disorder in the South-Asian region. An ethnic nonmigratory population inhabits the two regions, and consanguineous marriages are common. Based on these observations, the investigators firmly believe that there may be a founder gene in our populations responsible for the increased incidence of ACM. Our project includes a thorough phenotypic analysis ((ECG, Holter, and echocardiography) in the ACM patients and their first-degree relatives; cardiac MRI and high resolution endocardial bipolar and unipolar voltage mapping (using HD grid catheter) in the patients. The patient provided blood for the extraction of DNA will first undergo target panel sequencing for 20 known classic right-dominant ACM and left-dominant ACM. If this is negative for known pathogenic and likely pathogenic variants but identified novel variants of uncertain significance (VUS), then co-segregation analysis in family members will be performed. This technique can provide helpful information to reclassify VUSs. If both these are negative, then whole-exome 'trio' analysis will be performed, whch includes the proband and two family members, to triangulate from all 20,000 genes to a list of candidates for further interrogation. The investigators wish to provide comprehensive answers to the research question by combining the genetic analysis with phenotypic evaluation.
Burden, Mortality and Supply Costs in Intensive Care Unit Patients
BurdenDependency6 moreThis study systematically observes in a pragmatic trail under real world conditions the association between strategies of therapy (maximal therapy, withhold, withdraw) and treatment success in three endpoint related initial risk groups (high, intermediate, low risk) regarding three endpoints (burden, mortality and supply costs).
Descriptive and Risk Factors Analysis of All-cause Postoperative Death in Patients Undergoing Elective...
Postoperative DeathThe investigators are aimed to develop and externally validate a prediction model of clinical risk factors that quantifies postoperative death after elective surgery. We identify all patients treated with elective surgery, between 2000 and 2020, within the Wuhan Union hospital and all collaborators. The surgical patient cohort will be matched with the National Death database to determine the patient's postoperative death data. 60% patients were randomly selected to the development cohort. Logistic regression analysis for prediction of postoperative death adjusted for different covariates. The model was externally validated in the remaining 40% patients.
New Biomarkers of Neurological Outcome After a Sudden Cardiac Death
Cardiac Sudden DeathHypoxia Brain2 moreThe aim of the project is to establish the value of circulating microparticles as a new biomarker for neurological prognosis of patients recovered from sudden cardiac death who remain comatose.
Noninvasive Electrocardiographic Imaging for Individuals at Risk for Apparently Idiopathic Ventricular...
Ventricular FibrillationVentricular Arrythmia8 moreThis study aims to evaluate the electrophysiological properties of the heart conduction system in patients with unexplained polymorphic ventricular tachycardia (VT) and/or ventricular fibrillation (VF), in patients with specific genetic mutations regarding sudden cardiac death or sudden cardiac arrest, in their family members and in a control cohort. The electrophysiological properties will be measured with the relatively new technique ECG-Imaging (ECGI). Also a National Dutch registry for patients with unexplained polymorphic VT and/or VF and their family members will be created. By combining the data from the registry and the results of ECGI, The investigators hope to identity risk markers for patients at higher risk for apparently idiopathic ventricular fibrillation, and use these for an adapted flow chart for the 'general'population of patients at risk for unexplained polymorphic VT and/or VF. The investigators aim to be able to identify patients before the first arrhythmic event, and aim for better treatment strategies in the future.
End of Life Treatment Preferences of Latino Medicare Beneficiaries With Cancer
Advanced CancersObjectives: The primary objective of the research project is to investigate how declining health status influences the end-of-life (EOL) treatment preferences in Latino Medicare beneficiaries with cancer and to examine if and how these preferences are modified by predisposing characteristics (i.e., acculturation, education, medical mistrust, perceived racism) and/or provider-related characteristics (i.e., ethnicity, language used, provision of interpreters, or patient navigators). The specific aims are: To determine if declining functional status influences the end-of-life treatment preferences of older Latino Medicare beneficiaries with cancer. To determine if predisposing characteristics (i.e., acculturation, age, education, medical mistrust, perceived racism) and/or provider-related characteristics (i.e., ethnicity, language used, provision of interpreters, or patient navigators) modify the association between end-of-life treatment preferences and declining health status in older Latino Medicare beneficiaries with cancer. To identify if the end-of-life treatment preferences of Latino Medicare beneficiaries with cancer differ from those of older Medicare beneficiaries without cancer.
Finnish Genetic Study for Arrhythmic Events
Sudden Cardiac DeathAcute Coronary EventFinnish Genetic Study for Arrhythmic Events (FinGesture is a prospective case-control study assessing the characteristics and genetic background of consecutive series of autopsy verified out-of-hospital victims of SCD vs. survivors of an acute coronary event in a specific geographical area in northern Finland.
SCD-HeFT 10 Year Follow-up
Left Ventricular Systolic DysfunctionCongestive Heart Failure2 moreNo clinical trial that has examined the role of implantable cardioverter defibrillator (ICD) therapy in the prevention of Sudden Cardiac Death (SCD) has provided outcome data for longer than a few years. The NHLBI sponsored and placebo-controlled Sudden Cardiac Death in heart Failure Trial (SCD-HeFT) conducted from 1997 to 2003 had the largest number of patients and the longest average follow-up at 45.5 months. This study changed the national reimbursement policy for ICD therapy and remains the reference point for all other ICD evaluations in patients with congestive heart failure from ischemic or non-ischemic systolic dysfunction. Despite the outcome, the role of ICD therapy in the management of patients with heart failure has been questioned because of four principal concerns: numbers needed to treat to save a life, lead integrity over time, the negative consequences of shock therapy, and the cost of therapy. The purpose of this trial is to track down the remaining patients for a one-time follow-up regarding key outcome data.
End-of-Life Fear in Patients With End-Stage Lung Disease (COPD)
Chronic Obstructive Pulmonary DiseaseEnd-of-Life Fear2 moreThe aim of the study is to develop an interview to ask patients with COPD about their fear of death and dying, their needs and wishes at the end-of-life. Afterwards, the patients receive a brief psychological intervention to develop coping strategies for chronic illness. Beside this a general purpose of this intervention is to improve patients' quality of life.
ARrhythmias in MYocarditis
MyocarditisHeart Failure5 moreMyocarditis promotes the occurrence of serious cardiac arrhythmias and conduction disorders which may lead to sudden cardiac death, the need for catheter ablation of arrhythmia or implantation of a cardioverter-defibrillator or pacemaker. The aim of the study is to fill the evidence gap regarding the type and burden of arrhythmias in patients with myocarditis and their correlation with clinical parameters, biomarkers and additional tests. During a multi-center observational study, patients will be subjected to prolonged ECG monitoring. As a result, a risk scale will be created that can facilitate the identification of patients with an increased risk of arrhythmia and further specifying recommendations for therapeutic management.
