ESC heart failure guideline to integrate bounty of new meds


Today there are so many evidence-based drug therapies for heart failure with reduced ejection fraction (HFrEF) that physicians treating HF patients almost don’t know what to do them.

It’s an exciting new age that way, but to many vexingly unclear how best to merge the shiny new options with mainstay regimens based on time-honored renin-angiotensin system (RAS) inhibitors and beta-blockers.

To impart some clarity, the authors of a new HF guideline document recently took center stage at the Heart Failure Association of the European Society of Cardiology (ESC-HFA) annual meeting to preview their updated recommendations, with novel twists based on recent major trials, for the new age of HF pharmacotherapeutics.

The guideline committee considered the evidence base that existed “up until the end of March of this year,” Theresa A. McDonagh, MD, King’s College London, said during the presentation. The document “is now finalized, it’s with the publishers, and it will be presented in full with simultaneous publication at the ESC meeting” that starts August 27.

It describes a game plan, already followed by some clinicians in practice without official guidance, for initiating drugs from each of four classes in virtually all patients with HFrEF.

New indicated drugs, new perspective for HFrEF

Three of the drug categories are old acquaintances. Among them are the RAS inhibitors, which include angiotensin-receptor/neprilysin inhibitors, beta-blockers, and the mineralocorticoid receptor antagonists. The latter drugs are gaining new respect after having been underplayed in HF prescribing despite longstanding evidence of efficacy.

Completing the quartet of first-line HFrEF drug classes is a recent arrival to the HF arena, the sodium-glucose cotransporter 2 inhibitors.

“We now have new data and a simplified treatment algorithm for heart failure with reduced ejection fraction based on the early administration of the four major classes of drugs,” said Marco Metra, MD, University of Brescia (Italy), previewing the medical-therapy portions of the new guideline at the ESC-HFA sessions, which launched virtually and live in Florence, Italy, on July 29.

The new game plan offers a simple answer to a once-common but complex question: How and in what order are the different drug classes initiated in patients with HFrEF? In the new document, the stated goal is to get them all on board expeditiously and safely, by any means possible.

The guideline writers did not specify a sequence, preferring to leave that decision to physicians, said Dr. Metra, who stated only two guiding principles. The first is to consider the patient’s unique circumstances. The order in which the drugs are introduced might vary, depending on, for example, whether the patient has low or high blood pressure or renal dysfunction.

Second, “it is very important that we try to give all four classes of drugs to the patient in the shortest time possible, because this saves lives,” he said.

That there is no recommendation on sequencing the drugs has led some to the wrong interpretation that all should be started at once, observed coauthor Javed Butler, MD, MPH, University of Mississippi, Jackson, as a panelist during the presentation. Far from it, he said. “The doctor with the patient in front of you can make the best decision. The idea here is to get all the therapies on as soon as possible, as safely as possible.”

“The order in which they are introduced is not really important,” agreed Vijay Chopra, MD, Max Super Specialty Hospital Saket, New Delhi, another coauthor on the panel. “The important thing is that at least some dose of all the four drugs needs to be introduced in the first 4-6 weeks, and then up-titrated.”

Other medical therapy can be more tailored, Dr. Metra noted, such as loop diuretics for patients with congestion, iron for those with iron deficiency, and other drugs depending on whether there is, for example, atrial fibrillation or coronary disease.
