Simultaneous Assessment of FFR and SPECT

Patients who are previously scheduled for diagnostic coronary angiography will be approached for consent to be part of the study. If the patient is found to have one or two vessel disease and it is planned by the interventional cardiologist that FFR will be used, then the previously consented patient ...

Phase N/A

Telerehabilitation in Coronary Heart Disease

Cardiovascular diseases are the main cause of death worldwide. Aerobic fitness is related to long-term survival and a reduction in mortality and recurrent nonfatal myocardial infarction in subjects with cardiovascular disease. However, the majority of cardiac patients do not engage in enough physical activity to obtain benefits or in the ...

Cadmium-zinc-telluride (CZT) Imaging of Myocardial Blood Flow (MBF) (SPECT MBF)

Absolute myocardial blood flow (MBF) and myocardial flow reserve (MFR) are calculated measurements that are obtained using positron emission tomography (PET) nuclear imaging, from a myocardial perfusion imaging (MPI) stress test, due to the advanced capabilities of the PET camera technology. These calculations provide more diagnostic and prognostic information for ...

Correlation Between Quantitative Analysis of Coronary MRA and FFR

Coronary MR angiography is performed with a 3.0-T imager with 32-channel coils. Qunatitative analysis of coronary MR angiogram is evaluated on the basis of the signal intensity (SI) profile along the vessel. Quantitative analysis of coronary MR angiogram (QCMRA) is calculated as [1 - (SImin/SIref)] x 100, where SImin is ...

Is Glucagon-like Peptide-1 Insufficiency a Residual Risk in Coronary Artery Disease?

Recently, the investigators found that a significant proportion of subjects in a general population shows attenuated secretion of active GLP-1 in response to oral glucose loading and that the insufficient secretion of GLP-1 was independently associated with elevation of blood pressure (BP) (Yoshihara et al. PLoS One 2013;8:e67578). In that ...

Phase N/A

Quantitative Myocardial Perfusion Reserve by Cardiovascular Magnetic Resonance

Cardiac magnetic resonance (CMR) imaging is a wide available technique for the diagnosis of myocardial ischemia. However, myocardial first-pass perfusion evaluation has been limited due to the moderate accuracy of the currently available qualitative and semiquantitative methods used to assess myocardial perfusion, and due to the lack of efficient absolute ...

Phase N/A

Clinical Study to Evaluate the STENTYS Xposition S for Treatment of Unprotected Left Main Coronary Artery Disease

In the treatment of unprotected left main coronary artery (ULMCA) disease, previous mono-center studies have shown promising results with the previous generation of the self-expandable STENTYS stent (paclitaxel eluting stent, delivered via withdrawal of a sheath). The TRUNC study aims at assessing at large scale the Xposition S in the ...

Phase N/A

IRIS-Synergy Cohort in the IRIS-DES Registry

The purpose of this study is to evaluate the relative effectiveness and safety of Synergy stent compared to other drug eluting stents.

Phase N/A

Role of CYP2C19 Polymorphism in the Drug Interaction Between Clopidogrel and Omeprazole

Clopidogrel, an inhibitor of ADP induced platelet aggregation and activation, is one of the most commonly used drugs in patients with cardiovascular disease; coronary-stenting would not be possible without the robust anti platelet function of this drug. Clopidogrel is a pro-drug that is transformed through a series of hepatic cytochrome ...

Portuguese Registry on Interventional Cardiology

Cardiovascular disease remains the main cause of death in Portugal and approximately one quarter of these are directly to ischemic heart disease. In order to better characterize percutaneous coronary intervention in Portugal, the Portuguese Society of Cardiology has promoted the Portuguese registry on percutaneous coronary intervention. This will include all ...
