Percutaneous coronary intervention (PCI) is one of the main components in treatment artery disease (CAD) and especially its acute forms. Nevertheless, restenosis stented arteries, which significantly worsens course CAD, remains a significant clinical problem this technology. Prevention complication requires modern understanding complex pathogenetic mechanisms restenosis. Based on literature dat...
Intracoronary brachytherapy using beta or gamma radiation is currently the most efficient type of therapy for preventing the recurrence of coronary in-stent restenosis. Its implementation depends on the interaction among interventionists, radiotherapists, and physicists to assure the safety and quality of the method. The authors report the pioneering experience in Brazil of the treatment of 2 p...
BACKGROUND The objective of the present study was to assess the major immediate outcomes of eptifibatide therapy during intracoronary stent implantation. MATERIALS AND METHODS In an interventional study, patients undergoing percutaneous coronary intervention (PCI) were randomized into either the eptifibatide (n = 100) or the control (n = 107) group. In each group, demographic and clinical cha...
Dilated cardiomyopathy (DCM) and heart failure is a serious disease with a high morbidity and mortality rate in spite of optimal medical therapy. Although coronary artery disease is the main aetiology for the condition, a large group of patients have non-ischaemic DCM. Regenerative therapy with stem cells has been a focus to improve cardiac function, physical performance, and quality of life, a...
BACKGROUND Although clopidogrel is used to prevent subacute stent thrombosis, its safety and efficacy have not been compared with ticlopidine in a randomized manner in the United States. METHODS AND RESULTS Patients with successful intracoronary stent implantation were randomly assigned to therapy with ticlopidine or clopidogrel. Loading doses were administered immediately after the procedure...
OBJECTIVES We sought to demonstrate that brachytherapy reduces coronary spasm in refractory and highly symptomatic variant angina. BACKGROUND In some patients with variant angina due to extensive vasoconstriction, intensive drug therapy fails to sufficiently relieve symptoms. METHODS In 18 patients with frequent angina episodes despite triple anti-anginal therapy, coronary spasm was induced...
BACKGROUND Recent studies report that intracoronary administration of autologous bone marrow mononucleated cells (BM-MNCs) may improve remodeling of the left ventricle after acute myocardial infarction (AMI). Subgroup analysis suggest that early treatment between days 4 and 7 after AMI is probably most effective; however, the optimal time point of intracoronary cell administration has never bee...
Pump failure, ranging from ventricular dysfunction to acute cardiogenic shock, is now the leading cause of cardiac death. Efforts at temporary mechanical or pharmacologic support of the heart have been largely unsuccessful so that attention is now directed toward prevention of ventricular failure and limitation of myocardial infarct size or even outright prevention of infarction itself. In part...
Since its introduction in 1977, coronary angioplasty has become an established technique for the treatment of atherosclerotic coronary disease. Currently, more than 500 000 procedures are performed each year worldwide. However, two major problems remain unresolved. The first, post-angioplasty acute vessel closure, occurs in about 5% of cases. In this setting, intracoronary stenting has been ver...
