Heart TransplantationCoronary Artery Disease

The overall goal of this study is to determine if non-invasive imaging with state of the art CT coronary angiography can be used to screen for transplant coronary artery disease in the setting of heart transplant. Our current protocol at UCSF for heart transplant patients involves screening with stress tests as well as coronary angiograms with intravascular ultrasound to assess the diameter of the lumen of the coronary arteries and to assess wall thickness.

Cerebral Artery Stenosis, Coronary Artery Disease and Arrhythmia

StrokeCoronary Artery Disease1 more

There are many reports about the association of coronary artery disease (CAD) and cerebral artery stenosis (CAS), which had been proved to induce stroke and cognition decline after the revascularization including coronary bypass surgery (CABG) or percutaneous coronary intervention. Perfusion defect on nuclear brain scan is also noted to correlate with these neurological complications. On the other hand, the perioperative arrhythmia and following cerebral embolism was also attributed to be one factor inducing such neurological hazards. In the patients with coexistent CAD and CAS (1st group), and also the patients scheduled for CABG or percutaneous coronary intervention (PCI) (2nd group), we, the researchers at Far Eastern Memorial Hospital, attempted to integrate all the parameters mention above, including angiography of coronary and cerebral system, quantitative analysis of nuclear brain scan, biochemical profile, and signals of a new ambulatory device which could record the electrocardiograph (ECG) and electroencephalograph (EEG) simultaneously, in order to define the correlation between them. A chorological relation between EEG signals and ECG signals is our first target to be worked out. Thereafter, we hope to establish a regression model of all involved parameters according to the relation. Such a model, we believe, is essential not only to explain the post-CABG neurological complications, but to prevent them. Furthermore, for the undetermined ischemic stroke patients who had no obvious culprit artery or embolism source, the paroxysmal arrhythmia had long been regarded as the cause. Whether a paroxysmal atrial fibrillation, which had not been disclosed by routine ECG, could induce most of such a stroke is still not known. With this new ambulatory device which could record the electrocardiograph (ECG) and electroencephalograph (EEG) simultaneously, we want to answer the question.

Alternative Risk Markers in Coronary Artery Disease (ARMCAD)

Coronary Artery Disease

Estimating the risk of future cardiovascular events such as death, stroke and myocardial infarction using traditional risk factors (such as age, gender, smoking, diabetes, hyperlipidaemia and hypertension) is well accepted in patients with and without existing cardiovascular disease. These estimates are based on a number of robust observational studies, including the original Framingham study. While these methods apply reasonably well on a population level their application to the individual patients is not always straightforward. In addition, risk charts, such as those published by the Joint British Societies and American Heart Association, may underestimate risk in certain groups, notably diabetics and patients of Indo-Asian background, whilst overestimating risk in others (by as much as 50% in some studies).

Long-term Outcomes of Patients After Coronary Bifurcation Stenting

Coronary Artery DiseaseDeath1 more

The purpose of this study is to assess the long-term clinical outcomes after stenting bifurcation coronary artery lesions, and to determine whether simple or more complex techniques are associated with a better clinical outcome. We will also assess the risk factors associated with poorer clinical outcomes

Determination of the Prevalence and Prognostic Importance of Unrecognized Non-Q-wave Myocardial...

Coronary ArteriosclerosisMyocardial Infarction

The first aim of this study is to determine how often unrecognized myocardial infarction occur in patients using a magnetic resonance imaging (MRI) technique (known as delayed enhancement MRI), as compared to the electrocardiogram. The second aim of this study is to determine the severity of coronary heart disease of the patients with unrecognized myocardial infarction. The final aim is to determine how the presence of unrecognized myocardial infarction detected by the MRI affects lifespan.

Heart Rate Variability for Prediction of Perioperative Events

AnesthesiaCoronary Heart Disease

Patients with underlying cardiovascular disease are at high risk of perioperative cardiovascular events and death. Hemodynamic variables are controlled by the autonomic nervous system reflected by Heart Rate Variability. To investigate whether differences of HRV parameters predict perioperative cardiovascular events.

Impact of Patient-Prosthesis-Mismatch on Coronary Flow Reserve

Coronary Artery Disease

Complete normalization of CFR following AVR for aortic stenosis was observed only for stentless valves. Besides the superior hemodynamic performance this might explain the excellent long term results of this valve design.
