Could sustained monomorphic ventricular tachycardia in the early phase of a prime acute myocardial infarction affect patient outcome?

Objectives: Sustained monomorphic ventricular tachycardia (SMVT) in the course of a prime acute myocardial infarction is not a common arrhythmia and its prognostic significance has not been specifically elucidated. The aim of the study was to estimate the prognostic implications of the occurrence of sustained monomorphic ventricular tachycardia in the early phase (<72 h) of a prime acute myocardial infarction.

Methods: We studied 690 consecutive patients admitted to the coronary care unit with a diagnosis of a prime myocardial infarction.

Relation of C-reactive protein to the first onset and the recurrence rate in lone atrial fibrillation.

The presence of systemic inflammation determined by elevations in high-sensitivity C-reactive protein (hs-CRP) has been associated with persistence of atrial fibrillation (AF). The influence of inflammation markers, such as hs-CRP, on the recurrences of lone AF, however, has not been clarified. We tested the hypothesis of whether, in patients with a first paroxysmal episode of lone AF, the hs-CRP levels were elevated, and whether elevated hs-CRP could predict the recurrence rate of lone AF in patients without antiarrhythmic drugs.

Clotting state after cardioversion of atrial fibrillation: a haemostasis index could detect the relationship with the arrhythmia duration.

BACKGROUND: Fibrin D-dimer levels have been advocated as an useful clinical marker of thrombogenesis. HYPOTHESIS: We hypothesized that i) there is a hyperclotting state after the return of atrial fibrillation to sinus rhythm, ii) the measurement of plasma D-Dimer levels might be a good screening tool of this clotting status, and iii) the duration of arrhythmia influences the haemostasis measured by plasma D-Dimer levels. METHODS: Forty-two patients with atrial fibrillation undergoing cardioversion were divided into two groups: in Group A (n = 24,14 male, 56 +/- 11 years) the duration of atrial fibrillation was 72 hours or more (142.

Atrial fibrillation and hypercoagulability: dependent on clinical factors or/and on genetic alterations?

Unlabelled: It is well known that atrial fibrillation is associated with high incidence of thromboembolic events, propably due to a prothrombotic or hypercoagulable state. However, it is unclear whether or not there is any difference of this prothrombotic state in the clinical subgroups of atrial fibrillation patients, that is, in those with paroxysmal, persistent or permanent atrial fibrillation. From the other side the role of the arrhythmia duration on the changes of coagulative variables in atrial fibrillation patients is not clearly enough.
