What’s next in prevention of heart failure
Heart failure is one of the most expensive health care problems in the United States, and one of the deadliest. Today an estimated 6.5 million Americans have symptomatic heart failure. But that’s just the tip of the iceberg.
“Countless millions more are likely to manifest heart failure in the future,” Dr. Fonarow warned, noting the vast prevalence of identifiable risk factors.
It’s time for a high-visibility public health campaign designed to foster community education and engagement regarding heart failure prevention, he added.
“We have a lot of action and events around preventing atherosclerotic cardiovascular disease. But can you think of any campaign you’ve seen focusing specifically on heart failure? Heart failure isn’t one of the endpoints in the ACC/AHA Atherosclerotic Cardiovascular Disease Risk Calculator or even the new hypertension risk calculator, so we need to take this a whole lot more seriously,” the cardiologist said.

The 2017 focused update of the ACC/AHA heart failure guidelines endorsed a novel strategy of primary care–centered, biomarker-based screening of patients with cardiovascular risk factors as a means of triggering early intervention to prevent heart failure (J Am Coll Cardiol. 2017 Aug 8;70[6]:776-803). This strategy, which received a Class IIa recommendation, involves screening measurement of a natriuretic peptide biomarker.
The recommendation was based on evidence including the STOP-HF randomized trial (St. Vincent’s Screening to Prevent Heart Failure Study), in which 1,374 asymptomatic Irish patients with cardiovascular risk factors were randomized to routine primary care or primary care plus screening with brain-type natriuretic peptide testing. Patients with a brain-type natriuretic peptide level of 50 pg/mL or more were directed to team-based care involving a collaboration between their primary care physician and a specialist cardiovascular service focused on optimizing guideline-directed medical therapy. During a mean follow-up of 4.2 years, the primary endpoint of new-onset left ventricular dysfunction occurred in 5.3% of the intervention group and 8.7% of controls, for a 45% relative risk reduction (JAMA 2013 Jul 3;310[1]:66-74).
Dr. Fonarow reported receiving research grants from and serving as a consultant to the National Heart, Lung, and Blood Institute and a handful of medical companies.
