What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

4 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

The marked sentences are the ones the graph read a number from.

backgroundIn retrospective studies, statin therapy has been related to decreased incidence of sudden cardiac death (SCD) in heart failure. We sought to prospectively investigate a relation between atorvastatin therapy and SCD in patients with advanced chronic heart failure. METHODS AND

resultsWe enrolled 110 patients with heart failure with a left ventricular ejection fraction less than 30% and cholesterol level greater than 150 mg/dL. Fifty-five patients were randomized to atorvastatin (10 mg/day) (statin group); the remaining 55 patients received no statins (controls). Patients were followed for 1 year. At baseline, the two groups did not differ in age, sex, left ventricular ejection fraction, cholesterol, B-type natriuretic peptide, heart rate variability, or QT variability. During follow-up, 29 patients died (26%) and 2 patients (2%) underwent heart transplantation. Of the 29 deaths, 13 were attributed to pump failure, 15 were attributed to SCD, and 1 was attributed to noncardiac causes. All-cause mortality was lower in the statin group (9/55, 16%) than in controls (20/55, 36%) (P = .017). The same was true of the SCD rate (3/55 [5%] vs. 12/55 [22%], P = .012), but not of the pump failure (5/55 [9%] vs. 8/55 [15%], P = .38). SCD-free survival was 2.3-times higher in the statin group than in controls (P = .01).

conclusionsAtorvastatin therapy seems to be associated with decreased incidence of SCD in patients with advanced chronic heart failure. Larger studies are ongoing to confirm this hypothesis.
