CardioNerds Dr. Rohit Nathani, Dr. Atefeh Ghorbanzadeh, and Dr. Mariam Riad, discuss Obesity-related Heart Failure with Preserved Ejection Fraction (HFpEF) with Dr. John Ostrominski. This episode was produced as part of the CardioNerds Academy curriculum by House Jones under the guidance of House Chief, Dr. Mariam Riad and Academy Program Director, Dr. Gurleen Kaur. A matching review article will be published in US Cardiology Review, the official journal of CardioNerds. This episode highlights the diverse clinical phenotypes and complex, multifaceted pathophysiology of HFpEF. We take a deep dive into the therapeutic advances that represent paradigm shift in metabolic modulation aimed at improving outcomes in patients with HFpEF and metabolic syndrome. Audio editing by CardioNerds intern Pacey Wetstein. Enjoy this Circulation Paths to Discovery article to learn more about the CardioNerds mission and journey.

Pearls HFpEF is a constellation of symptoms often with different underlying pathophenotypes; cardiometabolic type is rising in incidence. Diagnosis is predominantly based on the clinical scenario along with supporting evidence from imaging modalities such as echocardiogram, cardiac MRI, and right heart catheterization. Cardiometabolic HFpEF is a complex syndrome characterized by dysregulated lipid metabolism, systemic inflammation, and hemodynamic abnormalities, all of which contribute to exercise intolerance and frailty. Lifestyle interventions, comorbidities management, and HFpEF therapeutics go hand in hand for comprehensive HFpEF care and offer opportunities for multispecialty collaboration to achieve optimal patient outcomes.
