Filter by:To compare treatment with aspirin alone versus the combined antiplatelet treatment aspirin and clopidogrel after 12 months of combined antiplatelet treatment following drug-eluting stent (DES) implantation.
The primary aim of the proposed research is to examine the relationship of lifestyle changes to new dietary, biomedical, and cellular parameters among new enrollees entering the "Dr. Dean Ornish Program for Reversing Heart Disease program" at 5 selected sites. Specifically, the investigators will add assessments of emerging cardiac risk factors (e.g., high sensitivity C-reactive protein [hsCRP], fibrinogen, lipoprotein(a) [Lp(a)], small, dense LDL, apolipoprotein B [apoB], apolipoprotein A-I [apo A1], the apoB/apoA1 ratio, homocysteine [Hcy], B-type natriuretic peptide [BNP], oxidized LDL, fasting insulin and waist-to-hip ratio [WHR]), protective and pathogenic dietary markers (e.g., folate, carotenoids, trans fatty acids), and measures of social support and cognitive functioning to the already existing assessment variables in the Multisite Cardiac Lifestyle Intervention Program (MCLIP). Hypothesis 1: Participation in the lifestyle program will not only be associated with favorable changes in standard coronary risk factors and quality of life, but also with improvements in emerging cardiac risk factors [hsCRP, Hcy, BNP, fibrinogen, Lp(a), small, dense LDL, apoB, apoA1, oxidized LDL, fasting insulin, and abdominal obesity] and psychosocial well-being (i.e., social support, and cognitive functioning). Hypothesis 2: High intake of emerging protective dietary factors and low intake of emerging pathogenic dietary factors will be associated with improvements in both standard and emerging cardiac risk factors (e.g. Hcy, oxidized LDL). Hypothesis 3: Degree of adherence to the lifestyle change program will be associated with differential improvement in standard coronary risk factors, emerging risk factors, cellular aging, and psychosocial variables.
Pulmonary hypertension is an important morbidity factor in patients having to undergo cardiac surgery with cardiopulmonary bypass (ECC). Milrinone used in inhalation, shows evidence of being a pulmonary vasodilator able to possibly contribute to the reduction of pressure on the pulmonary artery.
Patients with diabetes have worse outcomes after percutaneous coronary intervention (PCI) procedures, compared to those patients without diabetes. They are at increased risk of death, heart attack, or needing further procedures due to renarrowing of their coronary narrowings after implantation of a coronary stent. Studies have suggested that poor control of diabetes may be partly responsible for these poor outcomes. Thiazolidinedione drugs, such as pioglitazone, can improve the diabetes control and make the patient more sensitive to the effects of insulin. Preliminary studies suggest that pioglitazone may also help prevent renarrowing after PCI. This study was a pilot study designed to determine whether more aggressive treatment of the diabetes with the routine use of the drug pioglitazone (30mg/day for 6 months), in addition to the patient's usual diabetic medications adjusted to optimize their diabetic control (get glycated hemoglobin < 7%), could reduce the amount of tissue buildup within the stent after 6 months, compared to a group less aggressively treated without pioglitazone and their usual medications for diabetes. An intravascular ultrasound probe was used to assess the extent of tissue buildup within the stent and this was performed immediately after the PCI as a baseline and repeated after 6 months of therapy. The investigators hypothesize that the more aggressive diabetic treatment with pioglitazone would reduce the extent of tissue growth within the stent after 6 months of therapy.
Percutaneous coronary intervention (PCI) with bare metal stent (BMS) in patients with renal insufficiency has shown unsatisfactory results. Indeed, drug-eluting stents (DES) might reduce the incidence of restenosis and therefore of target lesion revascularization procedures in these patients. We therefore designed a prospective, randomized, multicenter, not-sponsored study to directly compare the efficacy in the prevention of clinical restenosis of everolimus-eluting stent (Xience V) and bare-metal stent (Vision) (both 2nd-generation DES and BMS, respectively), both implanted in the same patient with multivessel disease and renal insufficiency in order to obviate for the multiple and unpredictable characteristics of this high-risk population.
The investigators aim to assess if a new blood pressure medication, aliskiren, reduces various biomarkers of heart disease found in the blood in patients with a history of both heart disease and type 2 diabetes. The primary hypothesis is that aliskiren will reduce these biomarkers compared to a calcium channel blocker.
Studies show that depression is a risk factor for the development of coronary artery disease (CAD). Furthermore there is an increased occurrence of depression in patients with CAD. Among other mechanisms atherosclerosis is believed to play a central role regarding these notable associations between depression and CAD. Moreover, patients with late onset major depression have an increased number of small lesions found in the white matter of the brain, the so-called white matter lesions. The main goal of this project is to examine if CAD is associated with depression and/or white matter lesions. CAD is evaluated using coronary CT angiography. Depression is evaluated using a semi-structured diagnostic interview. White matter lesions are quantified using cerebral magnetic resonance.
The purpose of this study is to assess the safety of lodenafil carbonate in patients with coronaropathy, evaluating the response of the body facing physical effort, including both heart and respiratory components, with and without use of lodenafil carbonate 80mg.
Collect data on the use of the Angio-Seal Evolution Device in diagnostic and interventional patient populations.
We conduct this clinical trial to determine the effects of Xuefu Zhuyu capsule (based on TCM "Zheng Hou" theory) in helping recovery from coronary heart disease(CHD)after PCI and find out whether this kind of effecacy is much better within patients administered with TCM syndrome-based individualized medication.
