Virtual LV Lead Navigation in Patients With Ischemic Cardiomyopathy
CardiomyopathyIschemic CardiomyopathyPresently, the left ventricular lead is placed in a similar position for all patients. It is not known whether placing this lead in different positions in the heart will make the heart pump better. In this study, the investigator will collect measurements of the heart's electrical activity during an Electrophysiology Study (EP study or EPS). The hope is that these measurements will provide the know how to develop an individualized left ventricular lead placement "prescription" for patients referred for left ventricular lead pacing.
UMBRELLA - Incidence of Arrhythmias in Spanish Population With a Medtronic Implantable Cardiac Defibrillator...
CardiomyopathiesCardiac Arrhythmias1 moreThe purpose of the study is to analyze the different patient profiles implanted with an Implantable Cardiac Defibrillator (ICD) in Spain (guidelines adoption) and the patient prognosis as a function of clinical profile, implant indication, arrhythmias incidence, treatments or device programming.
The Genetic Basis for Familial Cardiomyopathy in Patients With Idiopathic Cardiomyopathy
CardiomyopathyIn many of the patients with cardiomyopathy, the etiology is not clear . In about 30% there is a family history of cardiomyopathy .Our aim is to study the genetics basis for these patients with cardiomyopathy with no clear etiology and who have a first degree family relative with cardiomyopathy as well.
Nitrite in Hypertrophic Cardiomyopathy (HCM) Study
CardiomyopathyHypertrophicInorganic nitrate, which is found at high levels in green leafy vegetables, is reduced to nitrite by bacteria in the mouth, swallowed, and absorbed in the stomach into the blood. Studies have shown that increasing the blood levels of nitrite improves the way that muscles use oxygen and energy during exercise, and potentially blood flow. Some people (~1 in 500) suffer from a type of genetic heart condition known as hypertrophic cardiomyopathy (HCM). This condition means that the muscle in the heart does not use energy well and becomes larger than average, meaning that they have to tap into the heart's 'energy reserves'. It is not known if nitrite has the same beneficial effects on heart muscle as on other muscles in the body. Our study will explore the mechanism by which nitrite may improve the function and energy status of the heart in HCM.
Anesthesia for Upper Endoscopy and Colonoscopy in Cardiac Patients With Acute Anemia
AnemiaCardiomyopathies1 moreThe aim of this study was to try to reduce the required dose of etomidate used in anesthesia for upper endoscopy and colonoscopy in critically ill cardiac patients who complain of severe anemia in cardiac intensive care units by using a low dose of ketamine, which helps to reduce the side effects of etomidate, the most important of which is its suppressive effect on the adrenal gland and the secretion of cortisol in such critical cases, while maintaining hemodynamic stability, and the patient's satisfaction.
Mechanisms Responsible for Cardiac and Skeletal Muscle Energetic Impairment in Diabetes
Diabetic CardiomyopathyDiabetes increases the risk of heart failure. This is mainly due to a disease of the blood vessels supplying the heart muscle and/or high blood pressure, but abnormal metabolism may also contribute. We plan to study the mechanisms involved in this abnormal metabolism, whilst also assessing the effects of a drug called Perhexiline which improves the abnormal metabolism that is present in diabetic patients before the development of heart failure.
A Pilot Project Exploring the Impact of Whole Genome Sequencing in Healthcare
Healthy Adults (Full Study and Extension Phase)Hypertrophic Cardiomyopathy or Dilated CardiomyopathyThe MedSeq™ Project seeks to explore the impact of incorporating information from a patient's whole genome sequence into the practice of clinical medicine. In the extension phase of MedSeq we are attempting increase our participant diversity by increasing targeted enrollment of African/African American patient participants.
Combination of Olmesartan Effect on Myocardial Viability of Patients With Dilated Cardiomyopathy...
Dilated CardiomyopathyThe study proceeds with prospective, randomized, open and controlled clinical trials. The subject of the investigator's study was the first patient diagnosed with dilated cardiomyopathy. Subjects who agreed to participate in the study and were determined to meet the selection / exclusion criteria were randomly assigned to each group, and the experimental group was treated with 20 mg of olmesartan and 5 mg of rosuvastatin for 6 months, and the control group is treated with 40 mg of valsartan and 5 mg of rosuvastatin.
Efficacy and Safety of Ivabradine to Reduce Heart Rate Prior to Coronary CT-angiography in Advanced...
Heart FailureCT Angiography8 moreThe aim of this study is to compare the effects of Ivabradine and metoprolol to reduce heart rate prior to coronary CT angiography in patients with advanced heart failure.
"Cardiac Rehabilitation in Patients With Hypertrophic Cardiomyopathy".
Cardiac RehabilitationHypertrophic cardiomyopathy (HCM) is the most common hereditary disease characterized by left ventricular hypertrophy and consequently left ventricular diastolic dysfunction. Its prevalence is estimated at around 0.2% in the general population. HCM is the most common cause of sudden cardiac death due to cardiovascular disease in young athletes, accounting for one third of deaths. HCM patients often have symptoms of heart failure. The ESC recommendations for heart failure (HF) from 2016 recommend exercise training regardless of ejection fraction to improve exercise capacity, quality of life, and reduction in hospitalizations due to HF. Meanwhile, for many years, HCM was equivalent to exercise training limitation. According to the 2014 ESC guidelines, it is recommended for patients with HCM to avoid sports practice. However the results of Edelmann et al. research, suggest that physical training leads to a significant clinical improvement in patients with diastolic dysfunction and thus may be beneficial in patients with HCM. In 2015 results of a first study were published (Klempfner et al.), which showed that the majority of HCM patients with moderate risk undergoing supervised physical training had improved physical performance and no significant adverse events were recorded. The study was limited by the small number of admitted patients (twenty), lack of control group and failure to perform cardio-pulmonary exercise test. The main goal of the study will be to evaluate the effectiveness and safety of comprehensive cardiological rehabilitation and telerehabilitation in patients with hypertrophic cardiomyopathy without left ventricular outflow tract obstruction with preserved systolic function. The study is planned to include 30 patients with HCM subjected to physical training and 30 patients with HCM in the control group treated as standard according to current guidelines, not subjected to physical training.
