BACKGROUND The overall effect of fruit and vegetable intake on urinary stone risk profile is not yet known. METHODS We studied the effect of a two-week period of fruit and vegetable elimination on urinary stone risk profile in 12 normal adults, and of supplementing the diet with a fair quantity of low-oxalate fruits and vegetables in 26 idiopathic calcium(More)
OBJECTIVE To assess the prognostic value of a history of hypertension in patients with acute myocardial infarction (AMI) treated with thrombolysis. DESIGN Retrospective adjusted analysis of outcome data of patients with AMI randomly allocated to treatment in a controlled study of alteplase versus streptokinase and heparin versus no heparin. SETTING A(More)
BACKGROUND The aim of this study was to compare the prognostic efficacy of cardiac troponin T (cTnT) and I (cTnI) in patients with clinical unstable angina. METHODS We studied 74 patients with chest pain at rest, electrocardiographic evidence of myocardial ischemia, and normal (<6.7 ng/mL) values of creatine kinase-MB. cTnT was measured with a commercial(More)
OBJECTIVE To assess the feasibility, safety and efficacy of thrombolysis in the Emergency Room of a Rural Hospital with no Coronary Care Unit, and subsequent transfer to the Coronary Care Unit of a City Hospital. DESIGN Prospective study, controlled with two parallel groups of consecutive patients (Group 1: Rural Hospital, Group 2: CCU Ravenna) and(More)
OBJECTIVE To assess the response of internal mammary artery (IMA) flow of hypertensive hearts to nitroprusside infusion. METHODS Fifteen patients were studied with a high-frequency duplex Doppler probe from the supraclavicolar approach. All the patients had undergone coronary artery bypass surgery with an IMA graft into the left anterior descending(More)
We monitored ST segment continuously for at least 3 h after the beginning of lytic treatment in 103 patients undergoing early coronary thrombolysis for acute myocardial infarction in order to ascertain whether this technique, which has been shown to be useful to assess recanalization of the infarct-related artery, is also able to identify the improvement in(More)
