The relation between platelet/lymphocyte ratio and the occurrence of no reflow in patients with ST-segment elevation myocardial infarction managed by primary percutaneous coronary intervention

open access: yesInternational Journal of the Cardiovascular Academy, 2021
Introduction: No reflow phenomenon following primary percutaneous coronary intervention (PCI) is a strong predictor of mortality. Platelet/lymphocyte ratio (PLR) is an indicator of long-term outcome in ischemic heart disease patients.

Solder paste reflow modeling

open access: yes, 2002
Solder paste printing and reflow are well established processes for producing solder joints in electronic assemblies. Solder paste consists of a dense suspension of solder particles in a liquid medium (vehicle) that acts as an oxide reducing agent (flux)

The Effect of Multiple Solder Reflows on the Formation of Cu6Sn5 Intermetallics and the Decomposition of SnAg3.0Cu0.5 Solder Joints in the Framework of Rework and Reuse of MLCC Components

open access: yesMetals
A rework of electronic assemblies and the reuse of electronic components are the most effective ways to reduce electronic waste. Since neither components nor substrates were developed with the intention of multiple usage, the question of how the ...

Comparison of RCHA2DS2-VASc score and CHA2DS2-VASc score prediction of no-reflow phenomenon in patients with ST-segment elevation myocardial infarction

open access: yesTürk Kardiyoloji Derneği Arşivi, 2020
Objective: No-reflow is a phenomenon that can arise due to factors such as distal embolization, microvascular occlusion, or prolonged myocardial ischemia and damage.

Effect of chronic pretreatment with beta-blockers on no-reflow phenomenon in diabetic patients with acute ST-elevation myocardial infarction undergoing primary percutaneous coronary intervention

open access: yesThe Egyptian Heart Journal, 2017
Background: No-reflow is an important factor as it predicts a poor outcome in patients undergoing primary angioplasty. In comparison with patients attaining TIMI 3 flow, patients with no-reflow have an increased incidence of ventricular arrhythmias ...

Effect of reflow profile parameters on surface mount chip resistor solder joint shear strength [PDF]

open access: yes, 2014
The focus of this study is on the effect of reflow parameters on the joint shear strength. Eight reflow profiles were developed using four factors at two levels of Taguchi design of experiment for 1206, 0805 and 0603 chip resistors.

Association Between Bifurcation Angle and Coronary No-reflow Following Primary Percutaneous Coronary Intervention in Patients

open access: yesBagcilar Medical Bulletin, 2021
Objective:Percutaneous coronary intervention (PCI) has become the treatment method for patients presenting with ST elevation myocardial infarction (STEMI). One of the well-known complications of PCI is no-reflow.
