CardioNerds (Amit Goyal, Daniel Ambinder, Carine Hamo, and Karan Desai) are honored to bring to you the Braunwald Chronicles. These are stories of discovery, innovation, accidents, perseverance, and more…truly these are the stories of cardiology, directly from a father of modern cardiology himself, Dr. Eugene Braunwald. Dr. Braunwald’s life and stories together are the saga which have brought us to this day in modern cardiology. So please join us for this wonderful series, as we journey through the history of cardiology, across 6 extraordinary chapters. We continue with Chapter 5 where Dr. Braunwald discusses his discoveries related to carotid sinus stimulation, limitation of infarct size & the open artery hypothesis. The open artery hypothesis has revolutionized the way we take care of patients with myocardial infarction. We thank Dr. Karan Desai, Editorial APD with the CardioNerds Academy, and fellow at University of Maryland, for all the work he put into designing the Braunwald Chronicles. Audio editing by Pace Wetstein.

CardioNerds join Dr. Inbar Raber and Dr. Susan Mcilvaine from the Beth Israel Deaconess Medical Center for a Fenway game. They discuss the following case: A 72-year-old man presents with two weeks of progressive dyspnea, orthopnea, nausea, vomiting, diarrhea, and right upper quadrant pain. He has a history of essential thrombocytosis, Barrett’s esophagus, basal cell skin cancer, and hypertension treated with hydralazine. He is found to have bilateral pleural effusions and a pericardial effusion. He undergoes a work-up, including pericardial cytology, which is negative, and blood tests reveal a positive ANA and positive anti-histone antibody. He is diagnosed with drug-induced lupus due to hydralazine and starts treatment with intravenous steroids, resulting in an improvement in his symptoms. Expert commentary is provided by UT Southwestern internal medicine residency program director Dr. Salahuddin (“Dino”) Kazi.

Pearls - A Drug's Adverse Effect Unleashes the Wolf




* The differential diagnosis for pericardial effusion includes metabolic, malignant, medication-induced, traumatic, rheumatologic, and infectious etiologies.



* While pericardial cytology can aid in securing a diagnosis of cancer in patients with malignant pericardial effusions, the sensitivity of the test is limited at around 50%. 



* Common symptoms of drug-induced lupus include fever, arthralgias, myalgias, rash, and/or serositis.



* Anti-histone antibodies are typically present in drug-induced lupus, while anti-dsDNA antibodies are typically absent (unlike in systemic lupus erythematosus, SLE).



* Hydralazine-induced lupus has a prevalence of 5-10%, with a higher risk for patients on higher doses or longer durations of drug exposure. Onset is usually months to years after drug initiation.




Show Notes - A Drug's Adverse Effect Unleashes the Wolf




* There is a broad differential diagnosis for pericardial effusion which includes metabolic, malignant, medication-induced, traumatic, rheumatologic, and infectious etiologies.

Welcome back to the CardioNerds Cardiovascular Prevention Series, where we are continuing our discussion of Glucagon-like Peptide-1 Receptor Agonists (GLP-1 RAs). This class of medications is becoming a household name, not only for their implications for weight loss but also for their effect on cardiovascular disease. CardioNerds Dr. Ty Sweeney (CardioNerds Academy Faculty Member and incoming Cardiology Fellow at Boston Medical Center), Dr. Rick Ferraro (CardioNerds Academy House Faculty and Cardiology Fellow at Johns Hopkins Hospital), and special guest Dr. Franck Azobou (Cardiology Fellow at UT Southwestern) sat down with Dr. Darren McGuire (Cardiologist at UT Southwestern and Senior Editor of Diabetes and Vascular Disease Research) to discuss important trial data on GLP-1 RAs in patients with heart disease, as well as recent professional society guidelines on their use. Show notes were drafted by Dr. Ty Sweeney. Audio editing was performed by CardioNerds Intern student Dr. Diane Masket.

Pearls and Quotes - GLP-1 Agonists: Diving into the Data




* Patients with diabetes and clinical atherosclerotic cardiovascular disease (ASCVD) or who are at high risk of ASCVD benefit from treatment with a GLP-1 RA.



* For persons with sufficient ASCVD risk and type 2 diabetes, GLP-1 RAs and SGLT2 inhibitors can, and often should, be used in combination. "Just like we don’t consider ‘and/or’ for the four pillars of guideline-directed medical therapy for heart failure with reduced ejection fraction, we shouldn’t parcel out these two therapeutic options...it should be both.”



* Setting expectations with your patients regarding injection practices, side effects, and expected benefits can go a long way toward improving the ...

Pearls - Sore Throat, Fever, and Myocarditis - It’s not always COVID-19




* The post-cardiac arrest ECG provides helpful information for diagnosing the underlying etiology.​



* Be aware of diagnostic biases - availability and anchoring biases are particularly common during respiratory viral (such as COVID-19, RSV) surges.



* Consider a broad differential diagnosis in evaluating myocarditis, including non-viral etiologies.



* Right heart catheterization provides crucial information for diagnosis and management of undifferentiated shock​.



* When assessing the need for mechanical circulatory support, consider the current hemodynamics, type of support needed,

Pearls and Quotes -  Lifestyle & Pharmacologic Management of Obesity




* Identify obese patients not just using BMI, but also using anthropometric measurements such as waist circumference (central adiposity).



* Lifestyle modifications are our first line of defense against obesity! Current recommendations emphasize caloric restriction of at least 500kcal/day, plant-based and Mediterranean diets, and getting at least 150 minutes of moderate-intensity weekly exercise.



* Dive into the root cause of eating and lifestyle behaviors. It is crucial to address adverse social determinants of health with patients to identify the driving behaviors, particularly among those individuals of low socioeconomic status.



* Newer weight loss agents are most effective at achieving and maintaining substantial weight loss, in particular Semaglutide (GLP-1) and Tirzepatide (GLP-1/GIP).
