BACKGROUND: Primary percutaneous transluminal coronary angioplasty (PTCA) is the treatment of choice for acute ST-segment elevation myocardial infarction (STEMI) in high-volume centres with experienced operators, but is often limited by a suboptimal microvascular perfusion due to distal embolization and impaired myocardial perfusion. The present study investigates whether routine use of ...

OBJECTIVE: Despite the success of antiproliferative therapies, restenosis remains a common problem after percutaneous transluminal coronary angioplasty (PTCA). Longer-term clinical results of brachytherapy (intracoronary radiation), the lack of long-term clinical results after implantation of drug eluting stents, and the occurrence of late thrombosis after both procedures leave room for skepticism. ...

We aimed to assess in-hospital outcomes of percutaneous transluminal coronary angioplasty (PTCA) in elderly subjects. A total of 1000 consecutive patients, who had all been admitted for interventional treatment of symptomatic coronary artery disease, were retrospectively analysed. Elderly patients (>/= 70 years of age) were more likely to be diabetic, ...

Previous studies have shown a high incidence of cardiovascular complications when noncardiac surgery (NCS) is performed after coronary stenting. No study has compared the outcomes of NCS after stenting compared with percutaneous transluminal coronary angioplasty (PTCA) alone. The records of all patients who underwent NCS within 3 months of percutaneous ...

Percutaneous transluminal coronary angioplasty (PTCA) has been recognized as a reliable treatment procedure for acute reversible ischemia and reperfusion. Ischemic reperfusion cycle in PTCA leads to the systemic inflammation and extensive tissue injury by the production of reactive oxygen species including nitric oxide (NO) radicals. In patients with coronary artery ...

Accelerated coronary artery disease remains the limiting factor in the long-term survival of heart transplant (HT) recipients and occurs in approximately 50% of patients by 5 years after transplantation. Sequelae of graft arteriosclerosis include congestive heart failure (due to acute or chronic ischemia), graft loss, and death. Unfortunately, as a ...

BACKGROUND: Plasma levels of endothelin-1 (ET-1) increase after coronary angioplasty (PTCA) due to endothelial injury during the procedure. ET-1 has been found in human endocardial and myocardial cells. It is not known whether ET-1 increases after thermal injury induced by radiofrequency catheter ablation (RFA). METHODS: We determined plasma ET-1 levels ...

Thrombolysis and percutaneous transluminal coronary angioplasty (PTCA) are kinds of procedures that can be used to restore the blood flow of previously ischemic myocardium that can be the result of excessive production of reactive oxygen and nitrogen species, such as superoxide and hydroxyl radical, hypochlorous acid and peroxynitrite. Reaction of ...

Versaci F - - 2004
BACKGROUND: Stent implantation for isolated stenosis of the proximal left anterior descending coronary artery (LAD) with preserved left ventricular function has been found to have a better clinical and angiographic outcome at one year than balloon angioplasty (PTCA). OBJECTIVE: To establish whether those results are maintained at five year follow ...
Labinaz Marino - - 2004
BACKGROUND: Potent inhibition of the platelet glycoprotein IIb/IIIa receptor has improved the acute outcome of patients presenting with acute coronary syndromes (ACS). For patients with ACS undergoing percutaneous balloon angioplasty without coronary stenting in the era of platelet glycoprotein IIb/IIIa blockade, the long-term prognosis is less clear. OBJECTIVE: To examine ...

Different protocols exist concerning the method and timing of post-coronary angioplasty arterial puncture site closure. Easy handling and good effectiveness are well-documented for the Femostop femoral artery compression system; however, no hard data exist concerning the relationship between heparin anticoagulation level and femoral artery compression time (FSCT). Thus, we prospectively ...
