BACKGROUND High-sensitivity C-reactive protein (hs-CRP) inflammatory biomarker is one of the best informative markers of prognosis of coronary artery disease (CAD) that has been studied. Some studies have found that hs-CRP has a direct correlation with CAD. The aim of this study was to determine the relationship between serum levels of hs-CRP and the severity of coronary artery stenosis in pati...
BACKGROUND The goal of this study was to evaluate the role of the fibrinolytic system in patients with unstable angina at rest associated with transient electrocardiographic changes. METHODS AND RESULTS Tissue plasminogen activator activity in plasma was comparable among patients with unstable angina (n = 17), patients with stable exertional angina (n = 10), and control patients with normal c...
441 Abstract: Cardiac troponin T (TnT) is a regulatory contractile protein not normally found in blood. Minor elevations of TnT in patients with unstable angina have been associated with an increased risk of subsequent death or Acute Myocardial Infarction (AMI). We used a neewly developed enzyme immunoassay for TnT to determine whether its presence in the serum of patients with unstable angina ...
We investigated the prognostic significance of new-onset angina in patients in whom coronary anatomic characteristics were known. New onset angina was defined as angina of less than 3 months duration. Consecutive patients (n = 1727) with significant coronary artery disease (diagnosed at cardiac catheterization) and who had not had a prior myocardial infarction or congestive heart failure were s...
The incidence of major complications after percutaneous coronary angioplasty (PTCA) of a totally occluded artery was assessed retrospectively. A total of 1649 PTCA procedures were analyzed. After exclusion of procedures for acute myocardial infarction or total occlusion that resulted from restenosis, 90 patients were selected. Forty-four patients (49%) had stable angina and 46 (51%) had unstabl...
A high proportion of patients with stable angina remains symptomatic despite multiple treatment options. Di'ao Xinxuekang (XXK) capsule and Compound Danshen (CDS) tablet have been approved for treating angina pectoris for more than 20 years in China. We compare the anti-anginal effectiveness of XXK capsule and CDS tablet in patients with symptomatic chronic stable angina. A randomized, multicen...
Right atrial pacing was performed in 21 patients with and 10 patients without coronary artery disease (CAD). The values for the control (C) and maximum paced (P) heart rate were similar in all patients. During pacing cardiac output did not change, and mean arterial pressure remained constant except for a slight increase during pacing-induced angina pectoris in 11 patients with CAD. Left ventric...
The hemodynamic responses of nine patients with severe coronary artery disease were studied during the precipitation of angina by both supine exercise and increasing rates of atrial pacing. Tension-time index and the first derivative of left ventricular pressure pulse (LV dp/dt) at the onset of angina were significantly higher (P < 0.01) in each patient when angina was induced by exercise than ...
Correspondence to: Professor Filippo Crea, Istituto di Cardiologia, Università Cattolica del Sacro Cuore, Largo A. Gemelli, 8, 00168 Roma, Italy; [email protected] _________________________ A mong patients undergoing coronary angiography because of angina typical enough to suggest coronary artery disease, 10–30% are found to have ‘‘normal’’ or ‘‘near normal’’ epicardial coronary arteries at ...
