Single-plane contrast ventriculography was performed on admission and before hospital discharge in more than 200 patients with acute myocardial infarction participating in a series of prospective clinical trials including intracoronary streptokinase, percutaneous transluminal coronary angioplasty (PTCA), intravenous tissue plasminogen activator (rt-PA) and thrombolysis (intravenous rt-PA or str...

OBJECTIVES To evaluate the safety of a low dose of heparin in consecutive stable patients undergoing elective percutaneous transluminal coronary angioplasty (PTCA). DESIGN Open prospective study in a single centre. PATIENTS 1375 consecutive patients had elective PTCA (1952 lesions: type A 11%, B1 34%, B2 36%, and C 19%). There were no angiographic exclusion criteria. INTERVENTIONS A bolus...

Patients with chronic segmental myocardial dysfunction may demonstrate improvement after coronary revascularization. To evaluate the early effects of percutaneous transluminal coronary angioplasty (PTCA) on resting left ventricular segmental function, we obtained serial two-dimensional echocardiograms 1.1 +/- 0.9 days before and 3.1 +/- 2 days after elective PTCA in 40 patients. Echocardiograms...

Restenosis is currently the major limitation of percutaneous transluminal coronary angioplasty (PTCA). Factors such as elastic recoil, migration of vascular smooth muscle cells from media to intima, neointimal proliferation and vascular remodeling underly the restenotic process. Presently there is no effective therapy available for restenosis. The role of platelets in the development of thrombo...

W hen Odysseus attempted to sail unharmed between Scylla and Charybdis, he could not have dreamt to ever be quoted in relation to restenosis after percutaneous transluminal coronary angioplasty (PTCA). To be truly successful, balloon dilatation should change the preexistent stenotic lesion to the extent that sufficient luminal widening is achieved and restenosis does not occur. Nevertheless, ap...

The main interest of this research is to discover clinical implications from a large PTCA (Percutaneous Transluminal Coronary Angioplasty) database. A case-based concept formation model D-UNIMEM, modified from Lebowitz's UNIMEM, is proposed for this purpose. In this model, we integrated two kinds of class membership and the index-conjunction class membership. The former is a polythetic clusteri...

To define the clinical significance of exercise-induced ST-segment elevation, exercise thallium-201 scintigraphy (Ex-Tl), left ventriculography and coronary arteriography were performed in 19 patients with anterior infarction less than 3 months previously. Seven of the 19 patients showed redistribution by Ex-Tl and underwent percutaneous transluminal coronary angioplasty (PTCA). In these 7 pati...

Background. Cilazapril is a novel angiotensin converting enzyme inhibitor with antiproliferative effects in the rat model after balloon injury. Methods and Results. We conducted a randomized, double-blind placebo-controlled trial to assess the effect of cilazapril in angiographic restenosis prevention after percutaneous transluminal coronary angioplasty (PTCA). Patients received cilazapril 2.5 ...
