BACKGROUND The purpose of this study was to assess the current care of elderly patients with non-ST-elevation acute coronary syndrome (ACS), with particular regard to the rate of use of antiplatelet drugs and the type of strategy, aggressive or conservative, in a population of consecutive patients admitted to 76 Coronary Care Units in Italy.

OBJECTIVE To test whether very early resumption of ambulation after femoral cardiac catheterisation is feasible and safe in patients with stable symptoms. DESIGN Prospective study in a selected group of men and women undergoing elective cardiac catheterisation, with next day physical inspection. SETTING Inpatient study. SUBJECTS Two hundred(More)
BACKGROUND Rescue coronary angioplasty (PTCA), though recommended by the guidelines, is not regularly performed after failed lysis in patients with ST-elevation acute myocardial infarction (AMI), and data from large contemporary studies are not available. The outcomes of a recent series of consecutive patients in our Center are presented. METHODS Between(More)
BACKGROUND Tissue proliferation is almost invariably observed in recurrent lesions within stents, and ACE, a factor of smooth muscle cell proliferation, may play an important role. Plasma ACE level is largely controlled by the insertion/deletion (I/D) polymorphism of the enzyme gene. The association among restenosis within coronary stents, plasma ACE level,(More)
BACKGROUND One-hundred consecutive procedures of elective coronary angioplasty were attempted in 95 patients, in the absence of any surgical stand-by. All patients had angina and/or signs of inducible ischemia. METHODS All patients and attending physicians were informed that no surgical coverage was available, and gave their consent. The choice was made(More)
Nineteen consecutive procedures of coronary stenting were attempted in 70 consecutive patients (27%) with evolving myocardial infarction due to threatened vessel reocclusion after primary (16 cases) or rescue (3 cases) angioplasty. Two patients were in cardiogenic shock. Stent delivery was successful in 18 patients, with a Thrombolysis in Myocardial(More)
Radiation exposure of cardiac catheterization laboratory staff is a known occupational hazard, and efforts are made to obtain dose levels which are "as low as reasonably achievable". This study assessed the reduction in staff radiation exposure using cine framing at 12.5 f s-1 during coronary cineangiography, instead of 25 f s-1. Thermoluminescent(More)
BACKGROUND The use of drug-eluting stents (DES) in patients at high risk of bleeding or thrombosis has not been prospectively studied; limited data are available in patients who have a low restenosis risk. OBJECTIVES This study sought to compare a hydrophilic polymer-based, second-generation zotarolimus-eluting stent (ZES) with a unique drug fast-release(More)
OBJECTIVES The aim of the study was to compare randomly assigned primary angioplasty and accelerated recombinant tissue plasminogen activator (rt-PA), in patients with "high-risk" inferior acute myocardial infarction (ST-segment elevation in the inferior leads and ST-segment depression in the precordial leads). BACKGROUND The ST-segment depression in the(More)
BACKGROUND In unstable angina early coronary arteriography is frequently performed, often followed by percutaneous revascularization with liberal use of stents. We intended to study the in-hospital outcome of patients receiving this treatment. METHODS From April 1997 to April 1998, patients submitted to coronary arteriography due to unstable angina, and(More)
