Serum uric acid (SUA) was an independent predictor of mortality in ST-segment elevation myocardial infarction patients with Killip I other than Killip IIIV. We read with much interest in Hajizadeh et al’s article that was recently published in the Journal of Cardiovascular and Thoracic Research.1 Hajizadeh et al enrolled acute STEMI patients undergoing thrombolytic therapies or primary percutan...

We extend the results of Denisov–Rakhmanov, Szegő–Shohat– Nevai, and Killip–Simon from asymptotically constant orthogonal polynomials on the real line (OPRL) and unit circle (OPUC) to asymptotically periodic OPRL and OPUC. The key tool is a characterization of the isospectral torus that is well adapted to the study of perturbations.

Four new species of Pilea (Urticaceae) from the Andes of Venezuela are described and illustrated: Pileamatthewii sp. nov., Pileamiguelii sp. nov., Pileanicholasii sp. nov., and Pileanidiae sp. nov. The affinities of these species and their positions within the informal classifications of Pilea proposed by Weddell and Killip are discussed. Notes on other species of Pilea found in Venezuela also ...

The authors present the Minnesota Heart Failure Criteria (MHFC), derived using latent class analysis from widely available items in the Framingham Criteria. The authors used 1995 and 2000 data on hospitalized Minnesota Heart Survey subjects discharged after myocardial infarction or heart failure (N = 7,379). Selected Framingham Criteria variables (dyspnea, pulmonary rales, cardiomegaly, interst...

This study tested the therapeutic impact of double-loading dose (i.e., 600 mg) versus standard-loading dose (i.e., 300 mg) of clopidogrel on ST-segment-elevation-myocardial-infarction (STEMI) patients undergoing primary-coronary-intervention (PCI).Between January 2005 and December 2013, a total of 1461 STEMI patients undergoing PCI were consecutively enrolled into the study and categorized into...

Background: Diastolic dysfunction may be the earliest marker which leads to progressive cardiac failure. Thus importance of detecting diastolic using tissue doppler echocardiography helps in preventing progression patients symptomatic congestive failure Objectives: 1. To find prevalence post myocardial infarction 2. study association between left ventricular and variables such as smoking, Diabe...

This work is in a stream (see e.g. [4], [8], [10], [11], [7]) initiated by a paper of Killip and Simon [9], an earlier paper [5] also should be mentioned here. Using methods of Functional Analysis and the classical Szegö Theorem we prove sum rule identities in a very general form. Then, we apply the result to obtain new asymptotics for orthonormal polynomials.
