Filter by: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.
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.
Neointimal coverage over stent strut is important for preventing the stent thrombosis. But, there is no data for the duration of complete formation of neointima om zotarolimus eluting stent (ZES). Previously the investigational observational data at 9 months showed most of stent strut was covered with neointima. Therefore, the investigators investigated the evaluation of neointimal coverage on 3 months after ZES implantation using novel OCT system, which is powerful intravascular imaging system having the higher resolution power.
Multicenter, case-control study, to collect data regarding incidences of late and very late drug-eluting stent thrombosis with the aim of identifying trends and possible correlates of stent thrombosis.
OBJECTIVES: The primary objective of this study is to assess the safety and efficacy of the Supralimus - Core™ Sirolimus Eluting Stent in de novo native vessel obstructive coronary artery disease. STUDY DESIGN: This is a single centre, prospective study. Approximately 105 patients were enrolled in the study. Patients were followed for twelve months post-procedure. All patients were to have a repeat angiography at 8 months. STUDY POPULATION: The study population consisted of approximately 105 patients with de novo native vessel obstructive coronary artery disease with no specific criteria. Patients from the daily practice were included. Patients had to meet all eligibility criteria for inclusion into the study. ENDPOINTS: The primary safety endpoint of the study is defined as Major Adverse Cardiac Events (MACE) at 30 days. The primary efficacy endpoint is the in-stent binary restenosis rate at 8-month follow-up determined by off-line Quantitative Coronary Angiography. The following secondary efficacy endpoints were assessed - Angiographic success - Procedure success - Quantitative Coronary Angiography derived vessel parameters in-stent and 5 mm proximal and 5 mm distal from the edge of the stent: acute gain, MLD, % DS, late loss, mean diameter. In-stent pre-, post and at 8-month follow-up. - Clinically justified Target Lesion Revascularization (TLR) at 12 months The following secondary safety endpoints were assessed: - MACE until 12 months - Device related SAEs until 12 months - Angiographic stent thrombosis: Subacute (after procedure until 30 days) and Late (after 30 days until 12 months)
Coronary artery disease has a high death toll in the Western world. Changes in lifestyle, particularly in nutrition and physical activity may significantly reduce a severe coronary atherosclerosis within one year without the use of medication. Several dietary studies have shown that not only the progress of coronary artery disease can be slowed down, but it may also increase significantly the survival of these patients. Up until now there is little known about therapeutic effects by complementary medicine. In particular, Traditional Tibetan medicine dietary programs have shown in few case reports that weight could be reduced in patients with obesity. Therefore, the investigators developed a specific dietary program for patients with coronary artery disease, who have an increased cardiovascular risk profile according to the criteria by the International Diabetes Federation (IDF).
