What Should be the Primary Treatment in Atrial Fibrillation: Ventricular Rate Control or Sinus Rhythm Control with Long-term Anticoagulation?

Recent trials have favoured ventricular rate control in atrial fibrillation (AF) management, however the present study investigated whether the restoration and maintenance of sinus rhythm with long-term anticoagulation therapy was superior in terms of embolic events and death in 534 patients with an AF duration > 48 h. Patients were randomized and received sinus rhythm control with either aspirin (group 1) or warfarin (group 2), or they were given ventricular rate control (group 3). Cardioversion to sinus rhythm was attempted in 42S patients and was successful in 387 (91.1%) of them. After 3 years' follow-up there were 12, two and 15 embolic events in groups 1, 2 and 3 respectively (significant difference between groups 1 and 2, and 2 and 3) and overall mortalities were four, two and 12, respectively (significant difference between groups 2 and 3). It is concluded that patients with an AF duration > 48 h might benefit considerably from sinus rhythm restoration and long-term warfarin therapy in terms of embolic events and mortality

Procalcitonin: a Novel Cardiac Marker with Prognostic Value in Acute Coronary Syndrome

Procalcitonin (PCT) is implicated as an inflammatory marker in early atherosclerosis. In order to investigate the clinical consequences of increased PCT levels in acute coronary syndrome (ACS), 77 patients (29 with non-ST-elevation myocardial infarction [MI], 34 with ST-elevation MI and 14 with unstable angina pectoris) were included and followed up for 6 months. The PCT levels were determined at initial presentation and within 48 h of admission. Five patients died during hospitalization and their PCT levels within 48 h of admission were significantly higher than survivors (n = 72) (0.588 +/- 0.56 versus 0.399 +/- 1.33 ng/ml, respectively). The PCT levels within 48 h post-admission in the nine patients who died within 6 months were also significantly higher compared with the survivors (0.451 +/- 0.44 versus 0.406 +/- 1.37 ng/ml, respectively). It is concluded that higher PCT levels within 48 h post-admission may reflect an inflammatory state that is associated with increased early and 6-month mortality
