Hot Phases Cardiomyopathy: Pathophysiology, Diagnostic Challenges, and Emerging Therapies.
Curr Cardiol Rep
January 2025
Center for Diagnosis and Treatment of Cardiomyopathies, Cardiovascular Department, Azienda Sanitaria Universitaria Giuliano Isontina (ASUGI), European Reference Network for Rare, University of Trieste, Via P. Valdoni 7, 34100, Trieste, Italy.
Purpose Of Review: Hot phases are a challenging clinical presentation in arrhythmogenic cardiomyopathy (ACM), marked by acute chest pain and elevated cardiac troponins in the absence of obstructive coronary disease. These episodes manifest as myocarditis and primarily affect young patients, contributing to a heightened risk of life-threatening arrhythmias and potential disease progression. This review aims to synthesize recent research on the pathophysiology, diagnostic challenges, and therapeutic management of hot phases in ACM.

Department of Internal Medicine, Division of Cardiovascular Medicine, University of Michigan, Ann Arbor, MI, USA.
Purpose Of Review: To summarize the available data on the use of immunosuppression therapies for the management of hot phases of disease and recurrent myocarditis in patients with desmoplakin cardiomyopathy (DSP-CMP).
Recent Findings: Occurrence of myocarditis episodes has been associated with worsening of outcomes in DSP-CMP. Multiple case reports and small case series have described potential benefit in using anti-inflammatory and immunosuppressive medications for the treatment of those episodes.
Safety and efficacy of immune checkpoint inhibitors in patients with pre-treatment reduced left ventricular function.

Division of Cardiology, Tel Aviv Sourasky medical Center, Tel Aviv, Israel.
Aims: Immune checkpoint inhibitors (ICIs) have revolutionized cancer treatment outcomes. However, the response varies across different populations, and their use may lead to life-threatening cardiovascular (CV) events. While pre-treatment reduced left ventricular ejection fraction (LVEF) is considered a marker for high-risk cardiotoxicity and a contraindication for anthracycline and HER2-targeted therapies, there is limited evidence on the safety and efficacy of ICIs therapy in patients presenting with pre-treatment reduced LVEF.

Department of Cardiology, University of Health Sciences Bursa Yuksek Ihtisas Training and Research Hospital, Bursa, Türkiye.
Background: Immune checkpoint inhibitors (ICI) are generally associated with rare cardiac side effects, yet instances like myocarditis can be fatal. Therefore, detecting and managing left ventricular dysfunction early in ICI therapy is vital.
Objectives: This study aims to evaluate whether left ventricular global longitudinal strain (LV GLS) is a predictor for early detection of cardiac dysfunction in patients receving ICI.
A retrospective analysis of cardiovascular outcomes of clozapine treated individuals within Hunter New England.
Intern Med J
January 2025
Cardiology Department, John Hunter Hospital Newcastle, Newcastle, New South Wales, Australia.
Background: Clozapine has demonstrated superiority in improving both positive and negative symptoms of treatment-resistant schizophrenia; however, there are associated treatment-limiting side effects, including myocarditis, cardiomyopathy and agranulocytosis.
Aim: This retrospective cohort study describes the prevalence of myocarditis, left ventricular (LV) dysfunction, cardiovascular risk factors and outcomes in a cohort of patients maintained on clozapine therapy.
Methods: Data were retrospectively collated from patients who had a diagnosis of schizophrenia, had been managed with clozapine at any stage during their care and undergone at least one echocardiogram.
