Platelet to Lymphocyte Ratio Predicts Contrast-Induced Nephropathy in Patients With ST-Segment Elevation Myocardial Infarction Undergoing Primary Percutaneous Coronary Intervention.

We investigated the relationship between platelet to lymphocyte ratio (PLR) and contrast-induced nephropathy (CIN) in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (pPCI). We enrolled 5719 patients in 3 tertiary hospitals from January 2005 to December 2010. The PLR was calculated as the ratio of platelet to lymphocyte counts on admission.

Impact of Platelet-to-Lymphocyte Ratio on Clinical Outcomes in Patients With ST-Segment Elevation Myocardial Infarction.

We investigated the association between platelet-to-lymphocyte ratio (PLR) and clinical outcomes (including all-cause mortality, recurrent myocardial infarction, heart failure, serious cardiac arrhythmias and ischemic stroke) in patients with ST-segment elevation myocardial infarction (STEMI). Based on PLR quartiles, 5886 patients with STEMI were categorized into 4 groups: <98.8 (n = 1470), 98.

Short- and Long-term Outcomes in Patients with Connective Tissue Diseases Undergoing Percutaneous Coronary Intervention.

Background: Coronary artery disease (CAD) is a leading cause of morbidity and mortality in patients with connective tissue diseases (CTDs). Risk factors and clinical characteristics in these patients are not equivalent to those in traditional CAD patients. The objective of this study was to report short- and long-term clinical outcomes in a consecutive series of patients with CTD who underwent percutaneous coronary intervention (PCI) with stent implantation.

Associations between human aldosterone synthase CYP11B2 (-344T/C) gene polymorphism and antihypertensive response to valsartan in Chinese patients with essential hypertension.

Aldosterone synthase is a mitochondrial enzyme that catalyzes the conversion of 11-deoxycorticosterone to the potent mineralocorticoid aldosterone. The gene encoding aldosterone synthase, CYP11B2, is associated with essential hypertension. But if the genetic variations in aldosterone synthesis could influence the antihypertensive response to Valsartan is not clear.

Impact of red blood cell distribution width on long-term mortality in patients with ST-elevation myocardial infarction.

Objectives: Recent studies have reported increased red blood cell distribution width (RDW) has been associated with adverse outcomes in heart failure and stable coronary disease. We investigated the association between RDW and risk of all-cause mortality in patients with ST-elevation myocardial infarction (STEMI) who were free of heart failure at baseline.

Methods: We enrolled 691 patients with STEMI who were free of heart failure at baseline confirmed by coronary angiography in Beijing Friendship Hospital from January 2007 to December 2008.

Admission glucose level and in-hospital outcomes in diabetic and non-diabetic patients with ST-elevation acute myocardial infarction.

Background: Hyperglycemia on admission is a predictor of an unfavorable prognosis in patients with ST-elevation Acute Myocardial Infarction (AMI). Data concerning associations between an elevated glucose level on admission and other in-hospital complications are still limited.

Methods: A total of 1,137 AMI patients with complete admission blood glucose level (ABGL) analysis were identified and stratified according to ABGL.

1-[5-(Anthracen-9-yl)-3-(4-nitro-phen-yl)-4,5-dihydro-1H-pyrazol-1-yl]ethan-1-one.

In the title compound, C(25)H(19)N(3)O(3), steric repulsion between the methine H atom and one of the anthryl H atoms seems to be concomitant with the considerable distortion of the anthryl fragment from planarity. The side rings of the anthryl subtend an angle of 9.57 (8)°, which is an extreme value among the known reliably determined structures.

Predictors and long-term prognosis of angiographic slow/no-reflow phenomenon during emergency percutaneous coronary intervention for ST-elevated acute myocardial infarction.

Objective: Angiographic slow/no-reflow during emergency percutaneous coronary intervention (PCI) in patients with ST-elevated acute myocardial infarction (AMI) may result in unfavorable outcomes. The aim of our study was to investigate the clinical factors and angiographic findings that predict slow/no-reflow phenomenon and the long-term prognosis of AMI patients with angiographic slow/no-reflow.

Methods: A total of 210 consecutive AMI patients, who underwent primary PCI within 12 hours of symptom onset were divided into a normal flow group (thrombolysis in myocardial infarction [TIMI] flow grade 3, n = 169) and a slow/no-reflow group (≤TIMI flow grade 2, n = 41), based on cineangiograms performed during PCI.

5-(Anthracen-9-yl)-3-(4-nitro-phen-yl)-1-phenyl-4,5-dihydro-1H-pyrazole.

In the title compound, C(29)H(21)N(3)O(2), the five-membered pyrazoline ring is nearly planar, the maximum deviation being 0.037 (3) Å. The anthracene ring system is approximately perpendicular to the central pyrazoline ring, making a dihedral angle of 86.

1-[5-(Anthracen-9-yl)-3-phenyl-4,5-dihydro-1H-pyrazol-1-yl]ethanone.

In the title compound, C(25)H(20)N(2)O, the pyrazoline ring is nearly planar [maximum atomic deviation = 0.0254 (17) Å]; but the anthracene ring system is distorted from a coplanar structure [maximum atomic deviation = 0.181 (3) Å], the dihedral angle between the outer benzene rings being 10.

Association between inflammatory mediators and angiographic morphologic features indicating thrombus formation in patients with acute myocardial infarction.

Background: Inflammatory mechanisms had played an important role in the occurrence and prognosis of acute myocardial infarction, inflammatory mediators was associated with adverse outcomes of acute myocardial infarction. This study tested the hypothesis that in the acute phase of myocardial infarction with ST-segment elevation, neutrophil count and high-sensitivity C-reactive protein are predictive of angiographic morphologic features that indicate thrombus formation in the infarct-related artery.

Methods: This retrospective study included 182 consecutive patients with acute myocardial infarction and ST-segment elevation.

Predictors and short-term prognosis of angiographically detected distal embolization after emergency percutaneous coronary intervention for ST-elevation acute myocardial infarction.

Objective: Distal embolization after percutaneous coronary intervention (PCI) is one of the major mechanisms of no-reflow. The aim of the study was to investigate clinical, angiographic predictors of distal embolization on angiography in patients with ST-elevation acute myocardial infarction (AMI) after PCI, and to assess the short-term prognosis of patients with distal embolization.

Methods: There were 318 consecutive AMI patients, who underwent primary PCI within 12 h of symptom onset, and were divided into distal embolization group (N = 97) and non-distal embolization group (N = 221), based on cineangiograms performed during PCI.
