Suboptimal optimization of atrio-ventricular (AV) and inter-ventricular (VV) timings could affect the clinical response of CRTd in T2DM patients. Thus, authors hypothesize that automatic sensor guided CRTd optimization could ameliorate clinical outcomes in patients with T2DM. However, authors will evaluate the effects of cardiac resynchronization therapy (CRTd) in patients with type 2 diabetes mellitus (T2DM) optimized via automatic vs. echocardiographic guided approach.Authors will conduct a prospective, multicenter study to recruit, from October 2016 to June 2019, patients with T2DM and heart failure (HF) candidate to receive a CRTd. After CRTd the patients will be optimized via automatic vs. echocardiographic guided approach.
Heart transplantation (HTx) is a procedure which is hindered by several complications. The HEARTS registry aims to allow the analysis of risk factors of all post-HTx complications. It consists in an exhaustive data collection at the moment of inclusion, i.e. HTx, knowing that patients underwent a full-fledged evaluation beforehand to evaluate their aptitude to being transplanted. Post-HTx complications include but is not limited to: all-cause mortality, AMR, ACR, CAV, AKI, sepsis, cancer, psychological disorders, metabolic disorders.
A study evaluating the safety and efficacy of the BioFreedom™ Biolimus A9™ coated Cobalt Chromium coronary stent system in patients at high risk of bleeding
The purpose of this study is to evaluate the natural course of coronary spasm patients presenting aborted sudden cardiac death and analyze risk factors.
This is an observational study designed to monitor the course of the fraction of reticulated platelets and the correlation thereof to major adverse cardiac and cerebrovascular events after noncardiac surgery.
The Diagnosis of acute coronary syndrome in patients presenting with acute chest pain is problematic when both, electrocardiogram and serum troponins are normal. Multidetector row computed tomography angiography (CTA) allows direct and rapid non-invasive visualization of coronary artery disease. The investigator's aim is to assess the diagnostic accuracy and safety of a novel diagnostic strategy based on MDCT as compared to a strategy using stress echocardiography in the workup of patient with chest pain, normal electrocardiogram, normal troponins and suspected coronary artery disease. Additionally, the cost associated with both strategies will be compared. Methods. A total of 150 patients with acute chest pain coming to the emergency room with intermediate probability of significant coronary artery disease, normal ECG and troponins will be prospectively randomized to MDCT or stress echocardiography with exercise. Patients showing coronary stenosis >50% at MDCT or abnormal stress echocardiography or inconclusive results will be admitted for further study. The primary endpoint of the study is the detection of an acute coronary syndrome, defined as typical or atypical angina with documented significant coronary artery disease (>50% stenosis) on invasive coronariography, a positive stress test or the occurrence of cardiac death, myocardial infarction or need for revascularization during 6 month follow-up. All MDCT angiograms and echocardiograms will be evaluated by an experienced radiologist and cardiologist.
Implantable cardioverter-defibrillator (ICD) therapy reduces mortality in patients with chronic heart failure and reduced left ventricular ejection fraction (LVEF) <36%. Nevertheless, patient selection for ICD therapy based on LVEF and NYHA functional class alone seems to have a low specificity and sensitivity: In 100 patients treated, the SCD-HeFT study prevented 7 deaths in 5 years. Therefore 93 patients have a risk of adverse effects, such as operation risk, infection, pneumothorax, lead dislocation, and inadequate icd therapy. On the other hand, patients with advanced or end stage heart failure might rather die off progressive heart failure death and thus not benefit from ICD therapy. It therefore seems appropriate and necessary to improve the individualized risk stratification in these patients. The aim of this study is to evaluate multiple cardiac biomarkers in a model predicting ventricular arrhythmias in patients on ICD therapy.
The study investigated 100 subjects, both genders, with chronic Chagas disease, confirmed by at least two distinct serological tests, and classified according to Los Andes classification in a long term follow-up aiming at identifying the predictive value of the signal-averaged electrocardiogram for cardiac death and ventricular tachycardia. All subjects admitted to the study were submitted to clinical history taking, physical examination, and noninvasive assessment, including blood pressure measurement, resting 12-lead surface electrocardiogram, 24h ambulatory electrocardiogram monitoring, M-Mode/two-dimensional echocardiogram, signal-averaged electrocardiogram in both time and frequency domains. Selected subjects were further submitted to treadmill stress test and coronary angiography to rule out coronary heart disease. Subjects were followed by non-investigational primary care assistance at three to six months scheduled clinical visits on an outpatients basis. Both noninvasive and invasive evaluation during follow-up were requested at discretion of primary evaluation. Adverse outcomes were ascertained by review of medical records and active contact to either study subjects or their relatives.
The purpose of this study is to use implantable loop recorder (ILR) in patients under chronic hemodialysis to record arrhythmias and conduction disorders and correlate them with hemodialysis parameters.
