UNLABELLED Simvastatin can prevent cardiac remodelling after myocardial infarction, though the exact mechanisms are uncertain. Myocardial no-reflow is associated with progressive cardiac remodelling. However, it remains unknown whether post-infarction treatment with simvastatin can also reduce myocardial no-reflow for which suppression of adenosine triphosphate-sensitive K+ (K(ATP)) channel ope...

Reflow profile has significant impact on solder joint performance because it influences wetting and microstructure of the solder joint. The purpose of this study is to investigate the effects of reflow profile and thermal shock on the shear performance of eutectic SnPb (SnPb) and Sn3.0Ag0.5Cu (SAC305) solder joints. Test boards were assembled with four different sized surface mount chip resisto...

OBJECTIVE The predictive value of five risk score models containing clinical (PAMI-PMS, GRACE-GRS, and modified ACEF-ACEFm-scores), angiographic SYNTAX score (SXS) and combined Clinical SYNTAX score (CSS) variables were evaluated for the incidence of three procedural complications of primary percutaneous coronary intervention (pPCI): iatrogenic coronary artery dissection, angiographically visib...

We examined the consequences of reflow on metabolic recovery following increasing periods of focal ischemia. The middle cerebral artery of 21 Sprague-Dawley rats was occluded with a snare ligature for 1, 2, or 6 hours followed by 5, 4, or 0 hours of reflow, respectively (seven rats in each group). All animals were injected with neutral red for visual confirmation that the affected regions were ...

Objectives: The goal of this study was to evaluate the long-term safety and efficacy of intracoronary epinephrine in reversing refractory no-reflow during primary percutaneous coronary intervention (PCI). Methods: A total of 248 consecutive patients with acute myocardial infarction who had been treated from September 2009 to November 2010 at the Cardiology Department of Turkiye Yuksek Ihtisas H...

INTRODUCTION The determinants of clinical outcomes in patients with acute ST-elevation myocardial infarction (STEMI) are still being debated. The aim of this study was to investigate the prognostic value of the no-reflow phenomenon and epicardial adipose tissue (EAT) thickness for clinical outcomes in patients undergoing primary percutaneous coronary intervention (pPCI) for STEMI. METHODS The...

BACKGROUND The treatment of acute myocardial infarction (AMI) is thought to restore antegrade blood flow in the infarct-related artery (IRA) and minimize ischemic damage to the myocardium as soon as possible. The present study aimed to identify possible clinical predictors for no-reflow in patients with AMI after primary percutaneous coronary intervention (PCI). METHODS A total of 312 consecu...

Abstract Introduction The no-reflow phenomenon is a serious complication of coronary intervention, especially in primary angioplasty and effective preventive measures are unknown. Methods Retrospective study all patients treated by single center through 4 years. We define as the absence flow immediately after stent angioplasty. variables associated with this were analyzed using binary logistic ...

What automated soldering methods can be considered for Mini-Circuits surface-mount components? There are two basic methods: reflow and wave soldering. Generally, reflow soldering can be done when (l) there are only surface mount components, or (2) these are present together with through-hole components and the latter will be soldered in a separate (wave soldering) step. The surface-mount compon...
