Background. The study aimed to verify the effect of primary percutaneous coronary intervention (PPCI) with <60 min door-to-balloon time on ST segment elevation myocardial infarction (STEMI) patients' prognoses. Methods. Outcomes of patients receiving PPCI with door-to-balloon time of <60 min were compared with those of patients receiving PPCI with door-to-balloon time 60-90 min. Result. Totally...

Following the Killip-Kiselev-Last method, we prove quantum dynamical upper bounds for discrete one-dimensional Schrödinger operators with Sturmian potentials. These bounds hold for sufficiently large coupling, almost every rotation number, and every phase.

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/ bcr-2016-214744 DESCRIPTION A 78-year-old man presented with progressively increasing dyspnoea, 2 weeks after experiencing ST elevation inferior wall myocardial infarction that was not thrombolysed because of late presentation. He was Killip class 2 with raised jugular venou...

Two hundred twenty-nine hospital survivors of acute myocardial infarction (MI) age 60 years or younger underwent coronary arteriography a median of 2 weeks after infarction and were followed a median of 24 months (range 6-62 months). For 62%, MI was the first presentation of coronary disease and 75% were in clinical Killip class I. Overall outcome was good: 96% survival at 1 year and 95% surviv...

BACKGROUND Primary percutaneous coronary intervention (PCI) is the main treatment for patients with ST-segment elevation myocardial infarction (STEMI). We investigated factors affecting the major complications of this procedure. METHODS This case-control study assessed 200 patients receiving primary PCI for STEMI. Effects of some factors including age, sex, coronary artery risk factors, left ...

Abstract. This note presents some equalities in law for ZN := det(Id− G), where G is an element of a subgroup of the set of unitary matrices of size N , endowed with its unique probability Haar measure. Indeed, under some general conditions, ZN can be decomposed as a product of independent random variables, whose laws are explicitly known. Our results can be obtained in two ways : either by a r...

An important study by van der Horst et al. (1) from the Netherlands reported in this issue of the Journal presents the results of the largest prospectively randomized trial of glucose-insulin-potassium (GIK) treatment for acute myocardial infarction (AMI) ever done (940 patients) and the first to be done in concert with rapid, successful percutaneous transluminal coronary angioplasty (PTCA). Th...

We study the properties of operators (−∆) ± V . We discuss a recent result of Killip, Molchanov, and Safronov [4] which states that if the negative spectra of these operators are discrete, then their positive spectra do not have gaps. Similar statements are also proved for more general operators of the form α(i∇) ± V and operators on the lattice Z. Here, we give a more detailed description of t...
