BACKGROUND Lone atrial fibrillation (LAF) is defined by the presence of atrial fibrillation unassociated with other evidence of organic heart disease. There are conflicting data concerning the prognostic importance, rate of embolic complications, and survival in subjects affected by this arrhythmia. METHODS AND RESULTS One hundred forty-five patients(More)
While coronary reperfusion arrhythmias are well defined in animal models, their prevalence and predisposing factors are still uncertain during pharmacologic coronary reperfusion in patients with acute myocardial infarction. In 80 patients, who underwent this procedure and had a continuous electrocardiographic monitoring (associated with a Holter recording(More)
Eighty-eight patients (84 men and 4 women; mean age 59.3 years) with stable exercise-induced angina pectoris were enrolled in this within-patient, placebo-controlled study aimed at comparing the efficacy of the continuous and intermittent (12 hour on, 12 hour off) application of transdermal nitroglycerin. Eighty-one patients completed the study. After a(More)
BACKGROUND Transient atrial and appendage dysfunction occurs after cardioversion of atrial fibrillation. It has been suggested that one component of early dysfunction is related to the method of restoration of sinus rhythm and it is less severe in patients undergoing pharmacological than electrical cardioversion. The aim of this study was to compare left(More)
Therapy with Vitamin K antagonists (VKA) effectively reduces the thrombosis risk in many clinical conditions. Genetic variants of vitamin K epoxide reductase (VKORC-1) are associated with increased VKA effect and bleeding risk. It is unknown whether these variants could also affect the long-term outcome in patients with high-dosage oral anticoagulation(More)
In a double-blind, within-patient, randomized, placebo-controlled, acute study, the effects at rest and on exercise capacity of two doses of a new transdermal therapeutic system (TTS), releasing respectively 10 and 20 mg of nitroglycerin (NTG) over 24 hours, were assessed in 15 outpatients with stable exercise-induced angina pectoris. A symptom-limited(More)
A patient with primary angina showed intermittent ST elevation (with and without chest pain), during two exercise tests performed on consecutive days; the same ST changes were also seen during the recovery phase. The electrocardiographic changes recorded in this patient may be considered an example of myocardial response to spasm-related ischemia.
BACKGROUND Non-rheumatic atrial fibrillation (NRAF) is a very common arrhythmia but its role in the prognosis and cardiovascular mortality is controversial. In particular, cause and predictors of death are not completely known. METHODS We analyzed the cause of death and the possible predictors of cardiovascular mortality in 664 outpatients (mean age 72(More)
The best anticoagulation level in patients with mechanical heart valve prostheses is still being debated. D-dimer, which detects the presence of cross-linked fibrin degradation products, has been demonstrated to be a useful marker of coagulation activation. This study was designed to verify whether heart valve prostheses in anticoagulated patients are(More)
