NMR-based plasma metabolic profiling in patients with unstable angina
Objective(s): Unstable angina (UA) is a form of the acute coronary syndrome (ACS) that affects more than a third of the population before age 70. Due to the limitations of diagnostic tests, appropriate identification of UA is difficult. In this study, we proceeded to investigate metabolite profiling in UA patients compared with controls to determine potential candidate...
متن کاملCoronary venous retroperfusion support during high risk angioplasty in patients with unstable angina: preliminary experience.
Synchronized coronary venous retroperfusion was used during coronary balloon angioplasty to support the ischemic myocardium of 20 patients with unstable angina and anatomy at high risk of a coronary event. Hemodynamics and left ventricular function were the major end points of the study. Coronary venous catheterization and retroperfusion were successfully performed in 15 patients. The target ve...
متن کاملCollateral circulation in patients with unstable angina.
Coronary collaterals were evaluated in 218 consecutive catheterized patients with unstable angina (defined as ischemic cardiac pain at rest associated with transient electrocardiographic changes). Collaterals were present in 106 patients (49 percent). The presence of collaterals correlated with the extent and severity of the coronary artery disease but not with age, sex, or risk factors. Among ...
متن کاملmean duration of ekg changes in patients with unstable angina
abstract introduction: chest pain in unstable angina is associated with ekg changes in t-wave and st-segment, which may help diagnose the disease. based on certain references ekg changes prolonged for more than 12 hours may be suggestive of non-q myocardial infarction. this study was conducted to assess the mean duration of ekg changes in patients with unstable angina. methods: this cross-sect...
متن کاملEffects of Nicorandil on the Clinical and Laboratory Outcomes of Unstable Angina Patients after Coronary Angioplasty
Introduction: Ischemic preconditioning mediated by potassium channels is a physiological protective mechanism, . It is hypothesized that Nicorandil, which is a potassium channel activator, could protect the heart via preconditioning. Materials and Methods:This clinical trial was conducted on 162 patients undergoing percutaneous coronary intervention (PCI) in Quem hospital, from Jan2013 to Jan 2...
