Evolocumab reduced total cardiovascular events in high-risk patients

The randomized trial found a 20% relative reduction versus placebo in first and subsequent events combined over a median follow-up of 4.6 years.

In a randomized trial, 12,257 patients with fatty buildup in their arteries or high-risk diabetes received the cholesterol-lowering drug evolocumab or placebo. None had a prior heart attack or stroke. All had low-density lipoprotein (“bad”) cholesterol of at least 90 mg/dL while on optimized cholesterol-lowering therapy.

Over a median 4.6 years, evolocumab reduced the combined rate of first and subsequent cardiovascular events by 20% relative to placebo. The measure counted deaths from disease in the heart’s arteries, heart attacks, strokes caused by blocked blood flow, and procedures to improve inadequate blood flow in arteries. From annualized event-rate differences, the researchers projected 55 fewer total events per 1,000 patients over five years: 31 first events and 24 subsequent events.

Why it matters

Cardiovascular disease becomes more common with age. Counting repeat events helps assess the longer-term benefit of intensive cholesterol lowering.

Caveats

The five-year absolute benefit was projected from event rates. The findings do not address lower-risk people or those with a prior heart attack or stroke; the abstract does not report the dose or adverse events.
