Precise risk estimation of mortality in cardiac surgery patients is often difficult. Main objectives of this study is to calculate mortality probability by two different risk score system and to inquire effects of informing anesthesiologist and surgical team; of score of the patient; on length of hospitalization and intensive care and also on actualized mortality.
The objective for this pilot study is to develop an optimized, clinically usable myocardial PET-MR perfusion protocol and to determine which of all data potentially available should be acquired for a clinical myocardial perfusion examination. Hypothesis: The hypothesis is that high resolution, high sensitivity DCE MRI could replace the rest PET myocardial perfusion imaging, significantly decreasing examination time and patient radiation dose while maintaining the comprehensive reference-quality PET myocardial stress perfusion coverage. The primary outcome will be comparison of diagnostic accuracy of each combination of imaging to detect clinically significant coronary artery stenosis (≥70% diameter stenosis).
To identify the high-risk patients who might have in-stent thrombosis after PCI with thromboelastography and to head-to-head compare two intensified antiplatelet therapeutic strategies of double-dosage Clopidogrel and triple antiplatelet therapy with Cilostazol with the standard antiplatelet therapy.
The remarkable improvement in survival of children with congenital disease has led to a continuously growing number of adults with congenital heart disease in the developed world. Many of these patients had had cardiac surgery at early age, the may live for many years with pressure overload, volume overload, systolic or diastolic dysfunction, cyanosis or any combination of the above. These past and ongoing cardiac insults often result in significant cardiac remodeling. A biomarker for fibrosis and remodeling may have enormous clinical and prognostic value for these patients. Serum biomarkers are now integrated in many fields in medicine. In cardiology, a number of biomarkers are used. In the last decade, our group has focused on the natriuretic peptides as markers for heart disease in infants and children. This resulted in many studies and more than 25 publications in the medical literature. We believe that the newly discovered cardiac marker, ST2, will emerge as an important addition to cardiac evaluation in the coming years.The aim of this study is to measure ST2 levels in patients with congenital right heart disease and correlate ST2 levels to clinical status, imaging and prognosis.
Centralized Pan-Algerian Survey on the undertreatment of hypercholesterolemia. The purpose of this study is to establish the proportion of patients on lipid-lowering pharmacological treatment reaching the LDL-C goals according to the Third Joint European Task Force guidelines in the survey population.
The purpose of this 4 group (2x2) pilot randomized controlled trial is to test the feasibility and logistics of incorporating genetic risk information (9p21)into standard Coronary Heart Disease (CHD) risk counseling or health coaching intervention (or both) in primary care at 2 Duke Clinics.
Using the 9 centers (Appendix B) involved with the planned multicenter NIRS comparative effectiveness trial the specific aims of this study are: 1. To demonstrate the feasibility of collecting rScO2 data from patients undergoing cardiac surgery in a multicenter study design. 2. To demonstrate the feasibility of using a standard algorithm for treating rScO2 desaturations during cardiac surgery in a multicenter study design.
Previous studies have examined the usefulness of pulse oximetry or oxygen saturation to screen for left-sided cardiac lesions. These studies have shown that the occurrence of critical congenital cardiac malformations among asymptomatic newborns is high; the technique of pulse oximetry is reliable for detection of ductal dependant left-sided lesions, simple to operate(requires little time and can be done in the newborn nursery) and is cost effective; there is effective follow-up test (heart ultrasound) and available interventions have an effect on outcome for diagnosed newborns. The importance of this research project is to examine the overall helpfulness of measuring oximetry in newborn infants using somatic oximetry, as well ast to prepare for a population based study in the state of Florida.
The purpose of this early feasibility study is to determine how a new transcatheter pulmonary valve will move and perform once implanted in the right ventricular outflow tract.
