• 434. Heart Failure: Advanced Therapies Evaluation with Dr. Michelle Kittleson

  CardioNerds kicks off its advanced therapies series with Chair of the CardioNerds Heart Failure Council, Dr. Jenna Skowronski, co-chair of the series, Dr. Shazli Khan, and Episode FIT lead, Dr. Jason Feinman. In this first episode, they discuss the process of advanced therapies evaluation with Dr. Michelle Kittleson, Professor of Medicine and Director of Education in Heart Failure and Transplantation at Cedars-Sinai. In this case-based discussion, they cover the signs and symptoms of end-stage heart failure, the initial management strategies, and the diagnostic workup required when considering advanced therapies. Importantly, they discuss the special considerations for pursuing left-ventricular assist device (LVAD) versus heart transplantation as well as the multidisciplinary, team-based approach needed when advanced therapies are indicated.  Notes were drafted by Dr. Shazli Khan.  Audio editing for this episode was performed by CardioNerds Intern, Julia Marques Fernandes.

Pearls Guideline-directed medical therapy (GDMT) is indicated in all heart failure patients and improves survival, but progressive symptoms and intolerance to GDMT can be warning signs of disease progression. The I-NEED-HELP mnemonic is an excellent reference when considering referral for advanced therapies (Figure).   Management of acute decompensation includes diuretics and possible inotropic support. The inotropic agent used should be whichever best suits your specific patient. Milrinone may result in more hypotension, whereas dobutamine may result in more tachycardia. Tachycardic and normotensive patients may do better with milrinone, while hypotensive patients with normal heart rates may do better with dobutamine. Notably, DoReMi found no difference between milrinone and dobutamine for patients with cardiogenic shock.  The initial diagnostic evaluation includes an echocardiogram, right heart catheterization (RHC), and often cardiopulmonary exercise testing (CPET) to objectively assess the status of the heart. Comprehensive labs, imaging and cancer screening are also needed to assess all other organs.   When making the decision to pursue advanced therapies, always ask:   Is the heart sick enough?   Is the rest of the body well enough?   These two questions provide a framework to guide if patients are optimal candidates for transplant versus LVAD.   The advanced therapies evaluation is a team sport! Patients will meet not only with advanced heart failure cardiologists, but also cardiac surgeons, psychiatrists, social workers, nutritionists and pharmacists. All team members are of critical value in the process.   Notes 1.) What are the key features of advanced cardiomyopathy, and when should providers consider referral for advanced therapies?   Advanced cardiomyopathy may present as recurrent hospitalizations for decompensated heart failure, intolerance to GDMT with symptomatic orthostasis and hypotension, and progressive symptoms of heart failure despite medical therapy.   The I-NEED-HELP mnemonic is a helpful tool to identify patients at risk of heart failure and is defined as follows: Need for Inotropic support, New York Heart Association (NYHA) Class IV symptoms, End-Organ Dysfunction, Ejection fraction <20%, Defibrillator shocks for ventricular arrhythmias, Recurrent HF hospitalizations, Escalating diuretic dose, Low blood pressure and Progressive intolerance of GDMT. See the Figure designed by Dr. Gurleen Kaur.  When patients demonstrate any of the above warning signs, they should be referred to advanced heart failure s...

• 432. Journal Club: The TRANSFORM-AF Trial with Dr. Sanjeev Saksena and Dr. Varun Sundaram

  Dr. Jeanne De Lavallaz and Dr. Ramy Doss discuss the results of the  TRANSFORM-AF Trial with expert faculty Dr. Sanjeev Saksena and Dr. Varun Sundaram.   The TRANSFORM-AF trial enrolled 2,510 patients with atrial fibrillation (AF), type 2 diabetes, and obesity across 170 Veterans Affairs hospitals to evaluate the impact of diabetes-dose GLP-1 receptor agonists on AF-related outcomes. Participants were assigned to receive either a GLP-1 receptor agonist, a DPP-IV inhibitor, or a sulfonylurea. The primary composite outcome included AF-related hospitalizations, cardioversions, ablation procedures, and all-cause mortality. Over a median follow-up of 3.2 years, GLP-1 use was associated with a 13% reduction in major AF-related events compared to other therapies. The study population was predominantly male, with a high prevalence of severe obesity (BMI >40 kg/m²) in whom the benefit appeared most pronounced. Notably, the observed benefit occurred despite only modest additional weight loss, suggesting potential non-weight-mediated effects of GLP-1 therapy  This episode was planned in collaboration with  Heart Rhythm TV with mentorship from Dr. Daniel Alyesh and Dr. Mehak Dhande.  CardioNerds Journal Club PageCardioNerds Episode PageCardioNerds AcademyCardionerds Healy Honor Roll CardioNerds Journal ClubSubscribe to The Heartbeat Newsletter!Check out CardioNerds SWAG!Become a CardioNerds Patron!

• 431. Atrial Fibrillation: Acute Management of Atrial Fibrillation with Dr. Jonathan Chrispin

  Dr. Naima Maqsood, Dr. Kelly Arps, and Dr. Jake Roberts discuss the acute management of atrial fibrillation with guest expert Dr. Jonathan Chrispin. Episode audio was edited by CardioNerds Intern Dr. Bhavya Shah. This episode reviews acute management strategies for atrial fibrillation. Atrial fibrillation is the most common chronic arrhythmia worldwide and is associated with increasingly prevalent comorbidities, including advanced age, obesity, and hypertension. Atrial fibrillation is a frequent indication for hospitalization and a complicating factor during hospital stays for other conditions. Here, we discuss considerations for the acute management of atrial fibrillation, including indications for rate versus rhythm control strategies, treatment targets for these approaches, considerations including pharmacologic versus electrical cardioversion, and management in the post-operative setting. CardioNerds Atrial Fibrillation PageCardioNerds Episode PageCardioNerds AcademyCardionerds Healy Honor Roll CardioNerds Journal ClubSubscribe to The Heartbeat Newsletter!Check out CardioNerds SWAG!Become a CardioNerds Patron! Pearls A key component to the management of acute atrial fibrillation involves addressing the underlying cause of the acute presentation. For example, if a patient presents with rapid atrial fibrillation and signs of infection, treatment of the underlying infection will help improve the elevated heart rate. Selecting a rate control versus rhythm control strategy in the acute setting involves considerations of comorbid conditions such as heart failure and competing risk factors such as critical illness that may favor one strategy over another. Recent data strongly supports the use of rhythm control in heart failure patients. Patients should be initiated on anticoagulation prior to pursuing a rhythm control strategy. There are several strategies for rate control medications with therapies including beta-blockers, non-dihydropyridine calcium channel blockers, and digoxin. The selection of which agent to use depends on additional comorbidities and the overall clinical assessment. For example, a patient with severely decompensated low-output heart failure may not tolerate a beta-blocker or calcium channel blocker in the acute phase due to hypotension risks but may benefit from the use of digoxin to provide rate control and some inotropic support. Thromboembolic prevention remains a cornerstone of atrial fibrillation management, and considerations must always be made in terms of the duration of atrial fibrillation, thromboembolic risk, and risks of anticoagulation. While postoperative atrial fibrillation is more common after cardiac surgeries, there is no major difference in management between patients who undergo cardiac versus non-cardiac procedures. Considerations involve whether the patient has a prior history of atrial fibrillation, surgery-specific bleeding risks related to anticoagulation, and monitoring in the post-operative period to assess for recurrence. Notes 1. Our first patient is a 65-year-old man with obesity, hypertension, obstructive sleep apnea, and pre-diabetes presenting for evaluation of worsening shortness of breath and palpitations. The patient has no known history of heart disease. Telemetry shows atrial fibrillation with ventricular rates elevated to 130-140 bpm. What would be the initial approach to addressing the acute management of atrial fibrillation in this patient? What are some of the primary considerations in the initial history and chart review? An important first step involves taking a careful history to understand the timing of symptom onset and potential underlying causes contributing to a patient’s acute presentation with rapid atrial fibrillation. Understanding the episode trigger determines management by targeting reversible causes of the acute presentation and elucidating whether the episode is triggered by a cardiac or non-c...
