Filter by:Cardiac rehabilitation (CR) is strongly recommended for patients with coronary heart disease. However, patient enrollment and completion of cardiac rehabilitation is low. This study will examine if a mobile phone intervention that uses a text messaging program can successfully promote participation in cardiac rehabilitation.
The purpose of this phase 1/2 clinical trial is to evaluate the efficacy and safety of allogeneic human umbilical cordstroma derived multipotent stem cells (hUCS-MSCs) in myocardial infarction (MI). All subjects will be taken into the bypass coronary surgery prior to the cell administration. This 2-year study comprise three independent groups, where the first group (n=20) will take no cells, second group will take autologous BM-MNCs (n=20), and third group (n=39) will be receiving allogeneic hUCS-MSCs. In all transplantations cells will be administered to the approximately 10 peri-infarct areas at one time. The infarct zone will be determined by the MR, SPECT and PET imaging. Only male subjects between 30-80 years of age. The efficiency of the therapy will be evaluated according to the parameters measured by MR, SPECT, and Echocardiography. All subject were taken into those measurements prior and 6, 12, 18 and 24 months after the operation.
Observe the effect of preliminary cyclosporine administration on different markers of cardiac ischaemia led by the aortic cross-clamp during coronary artery bypass surgery with Cardiopulmonary bypass.
When people undergo major surgery, they require intravenous supplementation of fluids for a number of reasons: - to compensate for no oral intake - to support blood pressure and organ function during and after surgery - to replace lost fluid or blood volume There are a variety of fluid choices doctors have to provide to patients, and it is still not definitively known whether some fluids are better than others in specific situations. This is a particularly interesting question in patients undergoing heart surgery because of the significant volume of fluids used over the entire course of hospitalization, including before the operation, during the operation, and after the operation. There has been some scientific evidence that the use of starch-based fluids (synthetic colloids) leads to better oxygen delivery to the organs with a smaller volume of fluid given, providing for better recovery from surgery. However, there has also been some scientific evidence that the use of these fluids can harm kidney function. Importantly, none of these large-scale studies were carried out specifically in patients undergoing heart surgery. The purpose of this study is to answer the question of whether the use of starch-based fluid in the heart surgery patient makes for a safer and faster recovery, causes kidney dysfunction, or makes no discernable difference.
This clinical trial will investigate the safety and effectiveness of IK-1001 (the liquid form of sodium sulfide) when used in Coronary Artery Bypass Graft (CABG) patients to potentially reduce the damage done to the heart during surgery. This study has 2 parts. Part 1 will first test 36 subjects at different doses (amount) of the study drug. There will be 6 different groups of 6 subjects each that will receive the study drug or a placebo. A placebo is a substance that will be prepared to look like the study drug but will contain no active ingredients. In Part 1, five subjects from each group will receive study drug (IK-1001) and one will receive a placebo. This first part of this study is also a dose (amount) escalation. This means that each group will be receiving a different dose of the study drug. The first group will receive the lowest dose, the second group will receive a slightly higher dose, and the third group a slightly higher dose until all six groups has been tested. You can not choose which group you will be in but prior to starting each new dose level, the data (information) from the previous dose level will have been reviewed by a group of qualified individuals to determine if it is safe to proceed to the next highest dose level. Part 2 will expand the study and will treat at least 158 (and up to 632) more subjects at a dose level that has been deemed safe from information collected from Part 1. Subjects in Part 2 of the study will have a 1 in 2 (50%) chance of receiving the study drug or placebo. Whether the subject gets study drug or the placebo will be randomly assigned (like the toss of a coin). The study drug or placebo will be given as an intravenous infusion (into the vein) for six hours while the subject is having their CABG surgery. The subjects will be followed up for 6 months after their CABG surgery.
This trial is a prospective, single-center Phase II randomized study to demonstrate the superior efficacy of Fondaparinux Sodium subcutaneous injections in patients undergoing CABG surgery (isolated and redo isolated) versus treatment with placebo. All consecutive patients scheduled for CABG surgery that meet the general inclusion and none of the exclusion criteria will be considered for enrollment in the study. Consecutive patients will be randomized on the day of admission prior to their CABG surgery into one of two groups. One group will be randomized to the placebo while the second group will receive 2.5 mg Fondaparinux Sodium injections. Both groups will receive routine mechanical prophylaxis as determined by the treating physicians. Group randomized to receive Fondaparinux Sodium will receive a 2.5 mg SQ daily drug dose starting 12 +/- 2 hours post-wound closure or the following day in the morning (at the discretion of the cardiothoracic surgeon). The second dose would be administered 24 hours later and the dosing will then be once a day. The group randomized to placebo will receive subcutaneous equivolume isotonic saline at the same time points described above. Patients randomized will receive a 2.5 mg dose of Fondaparinux Sodium or placebo subcutaneously for a total of 3-9 days post CABG with day 1 being the day of surgery. The drug will be discontinued if the patient is discharged before day 9. If the patient stays for more than 9 days inside hospital, a duplex would be obtained per protocol and further DVT prevention measures would be instituted per the discretion of treating physician. Patients will be assessed daily while hospitalized for any symptoms and adverse reactions and will undergo laboratory testing (CBC, PT/INR, PTT and UA) as specified in the protocol. Post-op day 3-9(no later than 2 days after the last preventive drug dose) patients will undergo the protocol specific lower limb venous duplex scan and earlier if symptomatic. Patients will also be contacted (phone/office visit) for follow-up 25-35 days post CABG to assess for signs or symptoms of deep venous thrombosis or thromboembolism and for any potential complications.
