New ACC Guidelines Propose Groundbreaking Framework for Diagnosing and Treating Myocarditis
The American College of Cardiology (ACC) has unveiled a groundbreaking approach to diagnosing and managing acute myocarditis, a condition characterized by inflammation of the heart muscle. The new guidance, published in the Journal of the American College of Cardiology, introduces a four-part staging system and a five-step care pathway, addressing critical gaps in current practices.
Mark Drazner, MD, MSC, clinical chief of cardiology at UT Southwestern medical Center in Dallas and chair of the document’s writing committee, emphasized the significance of this framework. “This is the first time four-step staging has been proposed in myocarditis,” he told Medscape Medical News. “It sets the stage for a new approach to assessing patients with myocarditis.”

The proposed staging system mirrors the latest heart failure guidelines, categorizing patients into four distinct stages:
- Stage A: Individuals at risk for myocarditis.
- Stage B: A novel classification for “asymptomatic” disease with evidence of myocardial inflammation.
- Stage C: Symptomatic myocarditis.
- Stage D: Advanced disease requiring intervention due to hemodynamic or electrical instability.
This framework aims to provide a clearer understanding of disease progression and guide tailored treatment strategies.However, Drazner acknowledged that further research is needed to fully define the implications of each stage and how patients transition between them.
The Five-Step Care Pathway
The ACC’s care pathway offers a structured approach to managing myocarditis, addressing key clinical questions:
- Triage: The guidance provides clear recommendations on when to refer patients to advanced heart failure centers. “We’ve provided very concrete,clinically relevant recommendations,” Drazner said.
- Diagnostic Tests: The pathway highlights two pivotal tests—endomyocardial biopsy, the gold standard but invasive option, and cardiac MRI, a noninvasive alternative. “The importance of cardiac MRI in this role may be somewhat new to some clinicians,” Drazner noted.
- Treatment: The recommendations address the use of immunosuppression, a contentious issue with no consensus among committee members. “We were transparent about where there was no consensus,” Drazner explained. The guidance also tackles the common question of when patients can safely return to sports or strenuous activities.
Controversial aspects and Challenges
The concept of “asymptomatic” myocarditis and the trajectories of disease progression are expected to spark debate. Additionally, the guidance highlights disparities in myocarditis outcomes, notably among racial groups. State-level data included in the report reveal that mortality rates are significantly higher for Black men and women.
Drazner cautioned that the increased surveillance recommended in the guidelines could pose challenges for underinsured or uninsured individuals, people of color, and those with limited access to care.
Key Takeaways

Breaking Down the New ACC Guidelines: A Conversation with Dr. emily Carter on Myocarditis Diagnosis and Treatment
The American College of Cardiology (ACC) recently introduced a groundbreaking framework for diagnosing and managing myocarditis, a condition marked by inflammation of the heart muscle. The new guidelines propose a four-stage classification system and a five-step care pathway, aiming to standardize care and improve patient outcomes. To delve deeper into these developments, we sat down with Dr. Emily Carter, a leading cardiologist and myocarditis expert, to discuss the implications of these guidelines and what they mean for patients and clinicians alike.
The Four-Stage Framework: A new Approach to Myocarditis
Senior Editor: Dr. carter, the new ACC guidelines introduce a four-stage framework for myocarditis. Can you walk us through what each stage entails and why this classification is important?
Dr. Emily Carter: Absolutely. The four-stage framework is a major step forward in understanding and managing myocarditis. Stage A identifies individuals at risk for myocarditis, such as those with viral infections or autoimmune conditions. Stage B is notably novel—it includes patients with asymptomatic disease but evidence of myocardial inflammation,which we’ve historically overlooked. Stage C covers symptomatic myocarditis, where patients experience clear clinical signs like chest pain or heart failure.Stage D represents advanced disease requiring urgent intervention due to complications like hemodynamic instability or arrhythmias.
This staging system helps clinicians better assess disease progression and tailor treatments accordingly. Though, as Dr. Drazner mentioned, we still need more research to fully understand how patients transition between stages and what interventions are most effective at each point.
The Five-Step Care Pathway: Streamlining Myocarditis Management
senior Editor: The guidelines also outline a five-step care pathway. Could you explain how this structured approach improves current practices?
dr. Emily Carter: Certainly. The care pathway provides a clear, step-by-step guide for managing myocarditis, which is especially helpful given the complexity of the condition. The first step, triage, emphasizes when to refer patients to advanced heart failure centers, ensuring they receive specialized care early on. The second step focuses on diagnostic tests, highlighting the importance of both endomyocardial biopsy—the gold standard—and cardiac MRI, which is noninvasive and increasingly valuable.
The third step addresses treatment,including the controversial use of immunosuppression and guidance on when patients can safely return to physical activities. These recommendations are designed to address common clinical dilemmas and provide clarity where consensus has been lacking.
Challenges and Controversies: Addressing Disparities and Asymptomatic Disease
Senior editor: The guidelines also touch on some controversial aspects, like the concept of asymptomatic myocarditis and disparities in outcomes. What are yoru thoughts on these issues?
Dr. Emily Carter: These are critical areas that need attention. The idea of asymptomatic myocarditis is intriguing but also contentious. Identifying inflammation in patients without symptoms could lead to earlier interventions, but it also raises questions about overdiagnosis and overtreatment. Additionally, the guidelines highlight significant disparities in myocarditis outcomes, particularly among Black men and women, who face higher mortality rates. Addressing these inequities requires not only better access to care but also targeted research to understand the underlying causes.
Another challenge is ensuring that the increased surveillance recommended in the guidelines is accessible to all patients, including those who are underinsured or lack access to specialized care. This is a systemic issue that goes beyond these guidelines but must be addressed to achieve equitable outcomes.
Key Takeaways: What Clinicians and Patients Need to know
Senior Editor: what are the key takeaways from these guidelines for clinicians and patients?
Dr. Emily carter: the new ACC guidelines represent a significant advancement in myocarditis care. By introducing a structured staging system and care pathway, they provide a clearer roadmap for diagnosis and treatment. Clinicians should familiarize themselves with the four-stage framework and the five-step care pathway, as these tools can help improve patient outcomes and address longstanding gaps in care.
for patients, the guidelines underscore the importance of early detection and specialized care. If you’re at risk for myocarditis or experiencing symptoms, don’t hesitate to seek medical attention. And for those with asymptomatic disease, these guidelines may lead to earlier interventions that prevent progression to more severe stages.
Ultimately, these recommendations are just the beginning. As Dr. Drazner noted, they open the door to much-needed conversations about how we can better serve patients with myocarditis. Continued research and collaboration will be essential to refine these guidelines and ensure they benefit all patients equitably.
