Rhythm or rate control in atrial fibrillation--Pharmacological Intervention in Atrial Fibrillation (PIAF): a randomised trial.

BACKGROUND: Atrial fibrillation is the most commonly encountered sustained cardiac arrhythmia. Restoration and maintenance of sinus rhythm is believed by many physicians to be superior to rate control only. However, there are no prospective data that compare both therapeutic strategies. METHODS: The Pharmacological Intervention in Atrial Fibrillation (PIAF) trial was a randomised trial in 252 patients with atrial fibrillation of between 7 days and 360 days duration, which compared rate (group A, 125 patients) with rhythm control (group B, 127 patients). In group A, diltiazem was used as first-line therapy and amiodarone was used in group B. The primary study endpoint was improvement in symptoms related to atrial fibrillation. FINDINGS: Over the entire observation period of 1 year, a similar proportion of patients reported improvement in symptoms in both groups (76 responders at 12 months in group A vs 70 responders in group B, p=0.317). Amiodarone administration resulted in pharmacological restoration of sinus rhythm in 23% of patients. Walking distance in a 6 min walk test was better in group B compared with group A, but assessment of quality of life showed no differences between groups. The incidence of hospital admission was higher in group B (87 [69%] out of 127 vs 30 [24%] out of 125 in group A, p=0.001). Adverse drug effects more frequently led to a change in therapy in group B (31 [25%] patients compared with 17 [14%] in group A, p=0.036). INTERPRETATION: With respect to symptomatic improvement in patients with atrial fibrillation, the therapeutic strategies of rate versus rhythm control yielded similar clinical results overall. However, exercise tolerance is better with rhythm control, although hospital admission is more frequent. These data may serve as a basis to select therapy in individual patients.

Quinapril, hydrochlorothiazide, and combination in patients with moderate to severe hypertension.

This 8-week, double-blind, multicentre study compared the efficacy and safety of the combination of quinapril and hydrochlorothiazide (HCTZ) with each drug as monotherapy. Outpatients with moderate to severe hypertension defined as supine diastolic blood pressure (DBP) > or = 105 mmHg and < or = 120 mmHg at the end of a 2 to 4-week placebo-baseline period were randomly assigned to one of the three treatments: once-daily 10 mg quinapril plus 12.5 mg HCTZ or monotherapy with these doses. After 4 weeks, the doses were to be doubled for the remaining 4 weeks. Three hundred and sixty-eight patients were randomized to double-blind medication; 346 completed the study. Seven patients withdrew due to lack of efficacy. Four patients withdrew due to side effects. In all three treatment groups, clinically significant reductions in DBP were achieved. Combination therapy was statistically more effective than each component taken as monotherapy. Adverse events were infrequent in all treatment groups. No patients experienced symptomatic hypotension or orthostatic hypotension.

Spatial and temporal processing in patients with Turner's syndrome.

Thirteen females with Turner's syndrome were examined for spatial abilitles and serial processing, and their performance was compared with that of normal females matched by age, intellignece, and socioeconomic class. Patients with Turners's syndrome performed significantly poorer on tests of spatial ability than controls, but only on spatial tests requiring the integration of isolated elements as synthetic wholes or the remembering of spatial configurations which could not be verbally mediated. Patients also performed less well than controls on tasks of serial processing when the tasks could not be mediated verbally. 2t was concluded that patients with Turner's syndrome may have a selective deficit in cortical functions that are lateralized to the right cerebral hemisphere.
