Hypercoagulability and haemodynamic abnormalities in atrial fibrillation.
Non-valvar atrial fibrillation confers a substantial risk for stroke and thromboembolism which is estimated to be between 4-5% and 12% per year depending on associated risk factors.'2 Recent studies have established the value of warfarin as thromboprophylaxis in atrial fibrillation; however, this treatment carries with it the inconvenience of regular monitoring of anticoagulation intensity and ...
متن کاملHaemostatic and haemodynamic abnormalities associated with left atrial thrombosis in non-rheumatic atrial fibrillation.
OBJECTIVE To evaluate the role of haemostatic and haemodynamic variables in left atrial thrombosis in non-rheumatic atrial fibrillation. DESIGN Case-control study. SUBJECTS One hundred and nine patients with non-rheumatic atrial fibrillation. INTERVENTIONS Peak blood velocity measured at three sites in the left atrium. Venous blood sampled for coagulant proteins and markers of haemostatic...
متن کاملIonic Determinants of Atrial Fibrillation and Ca Channel Abnormalities
Over the past several years, there has been increasing interest in understanding the basic mechanisms underlying atrial fibrillation (AF). The rise in interest is partly related to the prevalence of AF, which is presently the most common arrhythmia in clinical practice, and partly to the fact that the treatment of AF remains inadequate, making new insights into basic mechanisms essential for im...
متن کاملElectromechanical Abnormalities in Patients with Paroxysmal Atrial Fibrillation
Background: The loss of effective atrial contraction is associated with an increased thromboembolic risk. Aim: To study the electromechanical coupling of the atria in patients with paroxysmal atrial fibrillation (time of occurrence of the episodes <48 hours) using pulsed-wave tissue Doppler imaging. Materials and methods: The study included 51 patients (26 men, 25 women; mean age 59.84±1.60 yea...
متن کاملNovel Dielectric Coagulometer Identifies Hypercoagulability in Patients with a High CHADS2 Score without Atrial Fibrillation
BACKGROUND Recent reports showed that the CHADS2 score predicted the risk of strokes in patients without atrial fibrillation (AF). Although the hypercoagulability may contribute to the thrombogenesis, it has not been fully investigated due to a lack of a sensitive evaluation modality. Recently a novel dielectric blood coagulometry (DBCM) was invented for evaluating the coagulability by measurin...
