Vasodilator stress echocardiography allows semi-simultaneous imaging of left anterior descending (LAD) coronary flow and regional wall function. To assess the relative (and additive?) value of regional flow and function for noninvasive identification of angiographically assessed LAD disease in patients with chest pain syndrome, we studied 230 consecutive(More)
BACKGROUND Distal unprotected left main coronary artery (ULMCA) stenosis represents a technical challenge for interventional cardiologists. In this study, we compared 2-year clinical outcomes of different stenting strategies in patients with distal ULMCA stenosis treated with drug-eluting stents. METHODS AND RESULTS The survey promoted by the Italian(More)
BACKGROUND In-stent restenosis is notoriously difficult to treat by repeat catheter intervention because of its propensity for aggressive recurrent neointimal formation. This study sought to assess the effectiveness and safety of the sirolimus-eluting stent in the treatment of in-stent restenosis. METHODS AND RESULTS The study was designed as a(More)
BACKGROUND Spontaneous coronary artery dissection (SCAD) is an unusual cause of acute myocardial ischemia that in almost 50% of cases is followed by sudden death. The increasing frequency of SCAD diagnosis may reflect the widespread use of coronary angiography and percutaneous coronary interventions in acute coronary syndromes (ACS). The incidence of SCAD(More)
Spinal cord stimulation (SCS) is believed to be effective in treating refractory angina. The need for SCS-related chest paresthesia, however, has hitherto made impossible placebo-controlled trials. Subliminal (non paresthesic) SCS, however, might be also effective on anginal pain. In this trial we compared subliminal SCS with paresthesic SCS and with sham(More)
BACKGROUND Microvascular integrity is an essential determinant of favorable late outcome in reperfused myocardial infarction. Coronary flow reserve (CFR) can be assessed by transthoracic Doppler echocardiography and provides a functional estimate of microvascular integrity downstream from the patent infarct-related vessel. OBJECTIVE We sought to assess(More)
CONTEXT No specifically designed studies have addressed the role of primary percutaneous coronary intervention in patients with acute ST-segment elevation myocardial infarction (STEMI) presenting more than 12 hours after symptom onset. Current guidelines do not recommend reperfusion treatment in these patients. OBJECTIVE To assess whether an immediate(More)
The aim of our present study was to assess the value of nitroglycerin infusion during upright posture as a new provocative test for diagnosis of vasovagal syncope. To this purpose 40 patients with unexplained syncope (17 men and 23 women, mean age 47 years) and 25 asymptomatic control subjects with negative baseline head-up tilt underwent two other tilting(More)
Data are limited about the relative efficacy of drug-eluting stents (DESs) versus bare-metal stents (BMSs) for the treatment of unprotected left main coronary artery (ULMCA) stenosis. The survey promoted by the Italian Society of Invasive Cardiology on ULMCA stenosis was an observational study involving 19 high-volume Italian centers of patients with ULMCA(More)
AIMS To compare long-term clinical outcome following drug-eluting stents (DES) or bare-metal stents (BMS) implantation on lesions located at the ostium or the shaft of the left main in a large real-world population. The advent of DES decreased the risk of unprotected left main coronary artery (ULMCA) restenosis when compared with BMS, but it is unclear if(More)
