Filter by:The purpose of this study is to determine whether preoperative loading dose atorvastatin can prevent perioperative myocardial infarction during angiography and main adverse cardiac events 1 month after operation in stable angina, unstable angina and acute non-ST-segment elevation myocardial infarction patients undergoing elective coronary angiography and PCI, and determine whether its mechanisms are associated with microcirculation resistance.
Myocardial infarction (MI) outcomes strictly depend on the time to reponed the infarct-related coronary artery. Networks have been activated in the last years in many countries to achieve fast track access of patients with ST-elevation MI to hospital with h24 primary PCI availability or directly to Cath Labs. From 2011 a regional STEMI network have been formally activated in Piedmont. The aim of our registry is to monitor the activity of the STEMI network in the large suburban area of Novara (population of about 800.000 subjects).
A 2 by 2 factorial, multicenter, prospective, randomized, open-label, blinded endpoint trial. Patients undergoing primary PCI for STEMI will be eligible. Enrolled patients will be randomly assigned to the ticagrelor group or the clopidogrel group in a 1:1 ratio. After emergent coronary angiography, patients who have thrombolysis in myocardial infarction (TIMI) flow grade <2 in coronary angiogram will be randomized again, to either bolus intracoronary injection of morphine sulfate or saline in a 1:1 ratio. Randomization will be stratified by infarct location (anterior vs. non-anterior), and morphine use for pain control before study enroll (for only intracoronary morphine).
The new assay of troponins T (highly sensitive troponins) detects concentrations much lower than before. Few data are currently available on their kinetics during acute coronary syndrome, especially in regard to the correlation with CK MB. The aim of the present study is to describe the kinetic of highly sensitive troponins in acute coronary syndrome, to correlate it with the concentration of CK MB, and possibly to evaluate their prognostic value with respect to infarct size .
Background: When an acute myocardial infarction occurs, the artery supplying the infarct zone should be opened within twenty four hours of onset of infarction. This has clearly been shown to be beneficial. If the patient presents later than 24 hours of onset, at that stage a large part of the damage to the heart is irreversible. Intervening at this stage (beyond 24 hours is controversial). Some trials suggest that opening the artery even at this stage positively modifies the remodeling process while other trials suggest that such a benefit is not seen. Hypothesis: Opening an infarct related artery after 24 hours (until 6 months) and combining it with intracoronary stem cell therapy may provide incremental benefit.It is possible that the lack of benefit seen with late revascularization (>24 hrs) after MI may be offset by giving intracoronary stem cells after opening the artery.
Obstructive Sleep Apnea Syndrome (OSAS) is associated with stroke as a risk factor but little is known about the consequences of OSAS on the outcome and the survival after stroke. The aim of the investigators study is first to evaluate the outcome and the survival of patients with stroke depending of OSAS (presence and severity of OSAS) and second to compare the outcome and survival of patients with severe OSAS depending on the treatment of the syndrome with nocturnal continuous positive airway pressure. The investigators hypothesis is that OSAS is associated with worst survival and outcome and needs to be treated at the subacute phase of stroke.
Background It is commonly believed that a heart attack is caused by rupture of a plaque in the wall of the coronary artery, resulting in blood clots which impede blood flow. Currently, the investigators do not know whether heart attacks in patients who had a recent surgery are caused by the same disease process as those who did not have any surgery. This study will inform the investigators of very vital information about the cause of surgery-related heart attacks by taking images of coronary arteries using Optical Coherence Tomography (OCT). Images will also be taken from heart attack patients who did not have recent surgery, and the two groups will be compared. OCT imaging OCT is a relatively new imaging technology which is much better at taking images of the inside of the artery. OCT imaging procedure is carried out at the time of scheduled coronary angiogram, where a catheter with a mini-camera at its tip is advanced into the coronary artery, it will record video images of a length of the artery. These images will take approximately 3-4 seconds to obtain. Besides the OCT imaging being performed, the rest of the angiogram procedure is carried out in exactly the same way as it would normally proceed. The OCT study will provide doctors with new information about the cause of surgery-related heart attacks, and will guide doctors in treating and preventing heart attacks in patients who undergo surgery. Hypothesis The investigators hypothesize that features of acute plaque rupture will be more common in patients with non-surgery related heart attacks compared to those which occur following surgery. Design Two groups of patients will be recruited(>20 in each group): 1. non-surgery related heart attack patients 2. patients who suffered from a heart attack following an operation. Outcome measures Using OCT, plaque features in coronary arteries of patients with heart attacks from both the surgical and non-surgical groups at the time of coronary angiogram will be compared.
This is an open-label PET/CT (positron emission tomography/computed tomography) study to investigate the diagnostic performance of 68Ga-BNOTA-PRGD2 in evaluation of myocardial infarction. A single dose of nearly 111 MBq 68Ga-BNOTA-PRGD2 ( ≤ 40 µg BNOTA-PRGD2) will be intravenously injected into myocardial infarction patients. Visual and semiquantitative method will be used to assess the 68Ga-BNOTA-PRGD2 PET/CT cardiac images and compared to the 99mTc-MIBI SPECT myocardial perfusion images and the 18F-FDG metabolism images.
A prospective study of 700 patients with coronary artery disease will undergo non invasive evaluation of their carotid arteries by ultrasound and microwave radiometry. The patients will be followed up for 3 years and their outcome regarding the cardiovascular events (death, cardiac events, cerebrovascular events) will be recorded
The main objective of the GENOCOR project (Genetic mapping for cardiac risk assessment) is the setting up of a joint public/private laboratory (GENOCOR-LAB) dedicated to the development and testing of new cost-effective technologies exploiting the growing knowledge in the genomic correlates of cardiovascular diseases (CVD) and of their evolution; the data obtained by the GENOCOR-Lab should especially orient secondary prevention and specific treatment of ischemic heart diseases (IHD).
