Filter by:The study is testing the hypothesis, that the application of low dose erythropoetin beta (35 I.E./kg BW/week) for 6 months following successful coronary revascularization by PCI improves left ventricular remodeling as assessed by cardiac MRI.
The purpose of the study is to determine the usefulness of microvolt T wave alternans (MTWA) testing of patients that have had a heart attack and have decreased pumping ability of the lower chamber of their heart. MTWA testing is a non-invasive test used to detect the likelihood of developing abnormally fast rhythms in the lower chambers of the heart. The objective of the study is to prove that if a patient has a negative MTWA test, they will be less likely to develop abnormally fast and dangerous rhythms in the lower chambers of the heart. The results of the study will help doctors to determine which patients would benefit the most from having an Implantable Cardioverter Defibrillator (ICD) implanted.

This is a phase 1, single-blind trial to evaluate using autologous bone marrow mononuclear stem cells in ischemic cardiomyopathy patients. The patients must have a Left Ventricular Ejection Fraction (LVEF) of less than or equal to 45%. Once the patient meets all inclusion criteria, and no exclusion criteria are found, the subject is consented for the study, and extensive baseline testing is performed at St Luke's Hospital in Houston. Once all baseline testing criteria is met, the patient has their own bone marrow harvested and later that day the subject is taken to a cardiac catheterization lab where left ventricular electromechanical mapping using NOGA software (NOGA mapping) is performed and the processed stem cells are injected under electromechanical guidance into the affected areas of the left ventricle. The patient is usually discharged home the next day and returns for follow up visits at weeks 1, 2, 4, 6, 8, 12, months 6 and 12 and for phone call follow-up at months 4, 5, 7, 8, 9, 10, 11. Patients undergo extensive testing at most of these follow-up visits, including repeat cardiac catheterization with NOGA mapping at month 6 after stem cell injection.
The ABCD clinical study is designed to determine if a T-Wave Alternans (TWA) test is equivalent to an Electrophysiology Study (EPS) in predicting life-threatening heart rhythms in patients with ischemic heart disease, left ventricular dysfunction, and non-sustained tachycardia. Patients undergo both the TWA test and EP study and receive an Implantable Cardioverter Defibrillator (ICD)if either of the tests show the patient is at risk. The patient is then followed for 2 years. The incidence of a ventricular tachyarrhythmia events and total mortality are to be evaluated over the duration of the study.
