Filter by: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.
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.
Stenosis of the coronary arteries may be treated by balloon dilatation followed by the implantation of a metal stent. However, restenosis occurs in 10-20% of patients treated with bare metal stents (BMS). Restenosis and treatment of restenosis is associated with risk of myocardial infarction (MI) and death. Drug eluting stents (DES)release drugs to the vessel wall that delay or inhibit the process of restenosis. Some reports have found that DES are associated with risk of acute stent thrombosis, MI and death. The precise magnitude of this risk is not known. Current evidence is therefore insufficient to balance the long-term risk and benefit of BMS vs DES. The purpose of this trial is to compare the long-term effects on MI and total mortality of BMS vs DES. The trial will recruit 8000 patients from 8 Norwegian hospitals. The patients will be randomized to treatment with BMS or DES. Clinical events will be registered for 5 years after treatment. The study hypothesis is that there is no difference in the risk of death or myocardial infarction after treatment with BMS vs DES. The trial is initiated and run by university researchers and is sponsored by not-for-profit organizations.
