his article describes a nonlinear proportional and derivative T ( N P D ) controller and its use for both non-contact transient force control (NCTFC) (zero velocity when contact occurs) and contact transient force control (CTFC) (non-zero velocity when contact occurs). The key advantages of NPD control are its high disturbance rejection and robustness to time delay. We present a gain design met...

Background—Eptifibatide reduces major adverse cardiac events in patients with acute coronary syndromes undergoing percutaneous coronary intervention (PCI). Intracoronary bolus administration of eptifibatide may result in higher levels of platelet glycoprotein IIb/IIIa receptor occupancy in the local coronary bed, disaggregate thrombus in the epicardial artery and microvasculature, and thereby i...

OBJECTIVES The aim of this study was to evaluate how decreased plaque volume during percutaneous coronary intervention (PCI) affects coronary flow in patients with acute myocardial infarction (AMI). BACKGROUND Coronary flow after reperfusion therapy is a major determinant of clinical outcomes in patients with AMI. However, little is still known about the changes in coronary flow that appear aft...

OBJECTIVES We sought to evaluate and compare recently suggested parameters of reperfusion after angioplasty in acute myocardial infarction (AMI) for risk stratification during long-term follow-up. BACKGROUND Abnormal myocardial perfusion has a detrimental impact on survival. Several parameters of reperfusion have been evaluated in controlled study populations for risk stratification. METHOD...

BACKGROUND There is a paucity of information regarding the impact of the coronary collaterals on prognosis in type 2 diabetic (T2DM) patients. We developed a novel index, which considers not only the degree of collateral circulation but also the stimulus of collateral development, and investigated its prognostic value in T2DM patients with coronary artery disease (CAD). METHODS AND RESULTS On...

AIM To investigate the effect of abciximab on microvascular integrity and left ventricular (LV) functional recovery in patients with acute myocardial infarction (MI) treated by primary coronary angioplasty (PTCA). METHODS AND RESULTS Thirty-one patients (27 males; age 39-76 years) with first, acute MI (<6 h after onset) were randomized to receive either abciximab+primary PTCA (n=17) or primar...

Objective: This study was aimed at investigating the effects of preoperative treatment with a loading dose statins combined PCSK9 inhibitor on coronary blood perfusion and short-term cardiovascular adverse events in patients ST-segment elevation myocardial infarction (STEMI). Method: Sixty-five STEMI who had visited Shanxi Cardiovascular Disease Hospital between May 2018 2021 were enrolled stud...

Introduction: The research aimed to compare the characteristics and outcomes of myocardial infarction with non-obstructive coronary arteries (MINOCA) patients slow flow (CSF) vs. normal (no CSF) in a 5-year follow-up. Material methods: Between 2010–2015 were identified 111 as having final MINOCA diagnosis available calculated corrected TIMI frame count (cTFC). CSF was defined cTFC greater than ...

OBJECTIVES We hypothesized that elevated B-type natriuretic peptide (BNP) levels would be associated with a greater severity of angiographic disease and a greater extent of myocardium at risk. BACKGROUND Elevations of BNP have been associated with increased risk of adverse outcomes in patients with unstable angina and non-ST-segment elevation myocardial infarction (UA/NSTEMI). METHODS Of th...
