CardioNerds cofounder Dr. Daniel Ambinder, series co-chair Dr. Dinu Balanescu (FIT, Mayo Clinic), and episode lead Dr. Anjali Rao (FIT, UTSW) discuss training in cardio-oncology with Dr. Stephanie Feldman from Rutgers University. In this episode, the group discusses some of the most burning questions about educating the next wave of cardio-oncologists. As Dr. Feldman mentions, the projected number of cancer survivors is predicted to be around 24 million by 2024, underscoring the growing importance of cardio-oncology in our practice. We highlight some of the challenges facing trainees and training programs alike, including how to integrate cardio-oncology education into general cardiology training, the optimal structure for an advanced cardio-oncology fellowship, and the role of cardio-oncology in the inpatient setting. We also talk about the takeaways from the ACC Cardio-Oncology Leadership Council document. Dr. Feldman reflects on the importance of flexibility in education in the current landscape, drawing on her personal experience as a cardio-oncologist during the COVID-19 era. Notes were drafted by Dr. Anjali Rao. Audio editing was performed by student doctor, Shivani Reddy. This episode is supported by a grant from Pfizer Inc. This CardioNerds Cardio-Oncology series is a multi-institutional collaboration made possible by contributions of stellar fellow leads and expert faculty from several programs, led by series co-chairs, Dr. Giselle Suero Abreu, Dr. Dinu Balanescu, and Dr. Teodora Donisan.  Pearls • Notes • References • Production Team CardioNerds Cardio-Oncology PageCardioNerds Episode PageCardioNerds AcademyCardionerds Healy Honor Roll CardioNerds Journal ClubSubscribe to The Heartbeat Newsletter!Check out CardioNerds SWAG!Become a CardioNerds Patron! Pearls and Quotes - Cardio-Oncology: Training and Future Directions It may be possible to achieve “COCATS level 2” cardio-oncology training during general cardiology fellowship. A dedicated cardio-oncology year may appeal to trainees who want to achieve “COCATS level 3”, i.e., dedicate their practice to caring for patients with complex cardio-oncology needs, become involved in clinical trials, and lead cardio-oncology clinical and training programs. Supplemental learning opportunities for general fellows can include: Rotating in a cardio-oncology clinic, ideally attached to a National Cancer Institute-designated cancer center Multi-modality cardiac imaging Participating in cardio-oncology research Some currently available educational opportunities include:The International Cardio-Oncology Society (ICOS) weekly webinarsThe American Society of Echocardiography (ASE) webinars on global longitudinal strainThe American Society of Nuclear Cardiology lecture series on cardiac amyloidosis Cardio-oncology focused conferences, such as the American College of Cardiology’s (ACC) Advancing the Cardiovascular Care of the Oncology Patient and Memorial Sloan Kettering’s Cardio-Oncology Symposium. Each institution may have different inpatient cardio-oncology needs depending on whether there is a stand-alone cancer hospital or another format. Examples of inpatient consults that may benefit from having a cardio-oncologist involved include:Cardiovascular risk assessment prior to bone marrow transplant or cancer related surgery in a patient with known coronary artery diseaseImmune checkpoint inhibitor myocarditisChemotherapy-related cardiac dysfunction Management of systemic anticoagulation in a patient with high CHA2DS2-VASc and chemotherapy related thrombocytopenia. Show notes - Cardio-Oncology: Training and Future Directions The need for cardio-oncology experience is undeniable given the growing population of patients with cancer and cardiovascular disease, particularly given the number of anti-neoplastic therapies with potential cardiovascular side effects. There are several strategies for incorporating cardio-oncolo...

Question #30 A 65-year-old woman with a history of hypertension, type 2 diabetes mellitus, and coronary artery disease with remote PCI to the RCA presents for follow-up. She has stable angina symptoms that are well controlled with metoprolol tartrate 25 mg BID and are not lifestyle limiting. She takes aspirin 81 mg daily and atorvastatin 40 mg daily. Her LDL-C is 70 mg/dL, hemoglobin A1c is 7.0%, and eGFR is >60. In clinic, her BP is 118/80 mmHg. What is the next step in management?AIncrease atorvastatin for goal LDL-C < 55 mg/dLBNo change in managementCAdd isosorbide mononitrate 30 mg dailyDStop aspirinEStart a sulfonylurea Answer #30 Explanation The correct answer is A – increase atorvastatin for goal LDL-C < 55 mg/dL.In patients with established ASCVD, the ESC guidelines advocate for an LDL goal of < 55 mg/dL with at least a 50% reduction from baseline levels (Class I, LOE A). This patient has stable angina which is not lifestyle limiting; as such, further anti-anginal therapy is not necessary. She has known CAD with prior PCI, so aspirin therapy is appropriate for secondary prevention (Class I, LOE A). There is no indication for a sulfonylurea as her diabetes is well controlled. Notably, in persons with type 2 DM and ASCVD, the use of a GLP-1RA or SGLT2 inhibitor with proven outcome benefits is recommended to reduce CV and/or cardiorenal outcomes (Class I, LOE A).Main TakeawayFor people with established ASCVD, the ESC-recommended LDL-C goal is < 55 mg/dL with a goal reduction of at least 50%.Guideline Loc.Section 6.1 CardioNerds Decipher the Guidelines - 2021 ESC Prevention SeriesCardioNerds Episode PageCardioNerds AcademyCardionerds Healy Honor RollCardioNerds Journal ClubSubscribe to The Heartbeat Newsletter!Check out CardioNerds SWAG!Become a CardioNerds Patron!

The following question refers to Sections 10.2 of the 2022 AHA/ACC/HFSA Guideline for the Management of Heart Failure. The question is asked by Western Michigan University medical student and CardioNerds Intern Shivani Reddy, answered first by Mayo Clinic Cardiology Fellow and CardioNerds Academy House Faculty Leader Dr. Dinu Balanescu, and then by expert faculty Dr. Ileana Pina.

Question #24 Mr. E. Regular is a 61-year-old man with a history of HFrEF due to non-ischemic cardiomyopathy (latest LVEF 40% after >3 months of optimized GDMT) and persistent atrial fibrillation. He has no other medical history. He has been on metoprolol and apixaban and has also undergone multiple electrical cardioversions and catheter ablations for atrial fibrillation but remains symptomatic with poorly controlled rates. His blood pressure is 105/65 mm Hg. HbA1c is 5.4%. Which of the following is a reasonable next step in the management of his atrial fibrillation? A Anti-arrhythmic drug therapy with amiodarone. Stop apixaban. B Repeat catheter ablation for atrial fibrillation. Stop apixaban. C AV nodal ablation and RV pacing. Shared decision-making regarding anticoagulation. D AV nodal ablation and CRT device. Shared decision-making regarding anticoagulation. Answer #24 Explanation The correct answer is D – AV nodal ablation and CRT device along with shared decision-making regarding anticoagulation.” Maintaining sinus rhythm and atrial-ventricular synchrony is helpful in patients with heart failure given the hemodynamic benefits of atrial systole for diastolic filling and having a regularized rhythm. Recent randomized controlled trials suggest that catheter-based rhythm control strategies are superior to rate control and chemical rhythm control strategies with regards to outcomes in atrial fibrillation. For patients with heart failure and symptoms caused by atrial fibrillation, ablation is reasonable to improve symptoms and quality of life (Class 2a, LOE B-R). However, Mr. Regular has already had multiple failed attempts at ablations (option B). For patients with AF and LVEF ≤50%, if a rhythm control strategy fails or is not desired, and ventricular rates remain rapid despite medical therapy, atrioventricular nodal ablation with implantation of a CRT device is reasonable (Class 2a, LOE B-R). The PAVE and BLOCK-HF trials suggested improved outcomes with CRT devices in these patients. RV pacing following AV nodal ablation has also been shown to improve outcomes in patients with atrial fibrillation refractory to other rhythm control strategies. In patients with EF >50%, there is no evidence to suggest that CRT is more beneficial compared to RV-only pacing. However, RV pacing may produce ventricular dyssynchrony and when compared to CRT in those with reduced EF (≤ 50%),

In this episode, CardioNerds co-founder Amit Goyal joins Dr. Iva Minga, Dr. Kevin Lee, and Dr. Juan Pablo Salazar Adum from the University of Chicago - Northshore in Evanston, IL to discuss a case of primary cardiac diffuse large B-cell lymphoma. The ECPR for this episode is provided by Dr. Amit Pursnani (Advanced Cardiac Imaging, Fellowship program director, NorthShore University HealthSystem). Audio editing by CardioNerds Academy Intern, Dr. Akiva Rosenzveig. Case synopsis: A 77-year-old man with no significant medical history presents to the emergency department with progressive shortness of breath for 1 week. He reports an unintentional 15-pound weight loss in the prior month as well as constipation and abdominal/flank pain. On examination he was found to be tachycardic with a regular rhythm and further evaluation with a chest X-ray and chest CT scan demonstrated a large pericardial effusion. This was further investigated with an urgent echocardiogram that revealed a large pericardial effusion with a large mass attached to the pericardial side of the RV free wall, as well as signs of early cardiac tamponade. A pericardiocentesis was performed and 550mL of bloody fluid was withdrawn. The fluid was sent for laboratory analysis and cytology. A cardiac MRI demonstrated a large invasive mass in the pericardium and RV wall consistent with cardiac lymphoma. Cytology confirmed diffuse large B-cell lymphoma. Subsequent CT and PET scans did not find any other site of malignancy, giving the patient a diagnosis of primary cardiac diffuse large B-cell lymphoma. The patient underwent R-CHOP chemotherapy and was followed closely with repeat cardiac MRI and PET scans which demonstrated resolution of the cardiac mass at his one-year surveillance follow-up. This case was published in US Cardiology Review, the official journal of CardioNerds. To learn more, access the case report article here. CardioNerds is collaborating with Radcliffe Cardiology and US Cardiology Review journal (USC) for a ‘call for cases’, with the intention to co-publish high impact cardiovascular case reports, subject to double-blind peer review.

Pearls - A Mystery Mass in the Heart - Cardiac Lymphoma The most common cause of malignant cardiac masses is metastasis. Primary cardiac tumors are rare. Cardiac tumors are separated into 2 categories: benign and malignant. They are often differentiated based on their location and their degree of tissue invasion. Multimodality imaging is essential in the diagnosis, management, and surveillance of cardiac masses. A multidisciplinary team approach is invaluable for management of patients with cardiac tumors. Show Notes - A Mystery Mass in the Heart - Cardiac Lymphoma 1. What is the clinical presentation of cardiac masses? Cardiac masses can have a variable presentation. They can present with arrhythmias, angina, heart failure symptoms, or pericardial effusion. Patients can also be asymptomatic; the masses can be found incidentally on cardiac or chest imagining. 2. What is the differential diagnosis for cardiac masses? Cardiac masses are separated into benign and malignant. The most common malignant cardiac masses are metastases from a distant source. The location of the mass is important in narrowing the differential. 3. What imaging modalities are used to diagnose cardiac masses? Multimodality imaging is needed to describe the mass in detail and guide diagnosis. An echocardiogram is usually the first imaging modality. Cardiac MRI is a great modality that allows for the...

Dr. Amit Goyal (CardioNerds co-founder), Dr. Jessie Holtzman (House Faculty in CardioNerds Academy and cardiology fellow at UCSF), and Dr. Megan McLaughlin (CardioNerds Scholar and cardiology fellow at UCSF) discuss stimulant-associated cardiomyopathy with Dr. Jonathan Davis (Associate Professor at UCSF the Director of the Heart Failure Program at Zuckerberg San Francisco General Hospital) and Dr. Soraya Azari (Associate Clinical professor at UCSF, with specialty in hospital medicine, primary care, HIV medicine, and addiction medicine).   Methamphetamine-associated heart failure admissions have steadily increased in the United States over the past decade. Substance use disorders more broadly are thought to complicate at least 15% of all heart failure hospitalizations and amphetamine use has been shown to be an independent predictor of heart failure readmission across the country. At safety net and public hospitals, these numbers may rise even higher. This episode reviews the pathophysiology of stimulant associated cardiomyopathy, highlights treatment options for stimulant use disorder, and discusses novel models of co-management of heart failure and substance use disorder.  Notes were drafted by Dr. Jessie Holtzman.

Pearls - Stimulant-Associated Cardiomyopathy Though there are no pathognomonic traits of stimulant-associated cardiomyopathy, common echocardiographic features include biventricular dilated cardiomyopathy and/or pulmonary hypertension with a dilated, hypokinetic right ventricle and underfilled left ventricle. Enjoy CardioNerds Episode 312. Case Report: Life in the Fast Lane Leads to a Cardiac Conundrum to learn from a case of stimulant associated pulmonary arterial hypertension.   Not all cardiomyopathy in patients who use stimulants is due to stimulant use. Do your due diligence. Patients who use stimulants should undergo a broad work-up to diagnose the etiology of cardiomyopathy.   Tips for taking a substance use history:  Ask permission to discuss the topic.  Normalize the behavior.  Use specific drug names (also, learn the local drug nicknames!).  Ask about any history of prior treatment and periods of abstinence.  Screen for risk of harm or overdose   Try using a phrase like “I’m asking you this because I want to know if the way you are using drugs can impact your health and keep you safe.”  There are no FDA-approved medications to treat stimulant use disorder. Common off-label therapies include mirtazapine and bupropion/naltrexone.   Contingency management programs work off the principle of operant conditioning; they reward patients for maintaining abstinence from substance use.   For clinicians to seek assistance in providing treatment for stimulant use disorder, important resources include:   SAMSA (national help line 1-800-662-HELP or online resource locator)  HarmReduction.Org  Never Use Alone hotline (800-484-3731)  Show notes - Stimulant-Associated Cardiomyopathy 1. What are common clinical presentations of stimulant-associated cardiomyopathy?   Stimulants have multifactorial physiologic impacts, due both to pharmacologic properties (adrenergic stimulation and vasoconstriction) and direct toxic effects. Clinical manifestations may include hypertension, tachyarrhythmias, acute myocardial infarction, cardiomyopathy, pulmonary hypertension, aortic dissection, and sudden cardiac death.   On echocardiogram, stimulant-associated cardiomyopathy may manifest as biventricular dilated cardiomyopathy,

CardioNerds (Drs. Amit Goyal and Dan Ambinder) join Dr. Emily Lee (LAC+USC Internal medicine resident) and Dr. Charlie Lin (LAC+USC Cardiology fellow) as the discuss an important case of stimulant-related (methamphetamine) cardiovascular toxicity that manifested in right ventricular dysfunction due to severe pulmonary hypertension. Dr. Jonathan Davis (Director, Heart Failure Program at Zuckerberg San Francisco General Hospital and Trauma Center) provides the ECPR for this episide. Audio editing by CardioNerds Academy Intern, student doctor Akiva Rosenzveig. With the ongoing methamphetamine epidemic, the incidence of stimulant-related cardiovascular toxicity continues to grow. We discuss the following case: A 36-year-old man was hospitalized for evaluation of dyspnea and volume overload in the setting of previously untreated, provoked deep venous thrombosis. Transthoracic echocardiogram revealed severe right ventricular dysfunction as well as signs of pressure and volume overload. Computed tomography demonstrated a prominent main pulmonary artery and ruled out pulmonary embolism. Right heart catheterization confirmed the presence of pre-capillary pulmonary arterial hypertension without demonstrable vasoreactivity. He was prescribed sildenafil to begin management of methamphetamine-associated cardiomyopathy and right ventricular dysfunction manifesting as severe pre-capillary pulmonary hypertension.

Case Media - stimulant-related (methamphetamine) cardiovascular toxicity Pearls - stimulant-related (methamphetamine) cardiovascular toxicity 1. Methamphetamine, and stimulants in general, can have a multitude of effects on the cardiovascular and pulmonary systems. Effects of methamphetamine are thought to be due to catecholamine toxicity with direct effects on cardiac and vascular tissues. Acutely, methamphetamine can cause vascular constriction and vasospasm, while chronic exposure is associated with endothelial damage. Over time, methamphetamine can cause pulmonary hypertension, atherosclerosis, cardiac arrhythmias, and dilated cardiomyopathy. 2. Methamphetamines are the second most commonly misused substances worldwide after opiates. Patients with methamphetamine-associated pulmonary arterial hypertension (PAH) have more severe pulmonary vascular disease, more dilated and dysfunctional right ventricles, and worse prognoses when compared to patients with idiopathic PAH. Additionally, patients with methamphetamine-associated cardiomyopathy and PAH have significantly worse outcomes and prognoses when compared to those with structurally normal hearts without evidence of PAH. Management includes multidisciplinary support, complete cessation of methamphetamine use, and guideline-directed treatment of PAH. 3. The diagnosis of pulmonary hypertension (PH) begins with the history and physical, followed by confirmatory testing using echocardiography and invasive hemodynamics (right heart catheterization). Initial serological evaluation may include routine biochemical, hematologic, endocrine, hepatic, and infectious testing. Though PH is traditionally diagnosed and confirmed in a two-step, echocardiogram-followed-by-catheterization model, other diagnostics often include electrocardiography, blood gas analysis, spirometry, ventilation/perfusion assessment,

Question #29 What percentage of the European population currently meets the recommended physical activity guidelines (150 minutes moderate-intensity activity weekly or 75 minutes vigorous-intensity activity weekly)?A<10%B10-25%C25-50%D50-75%E>75% Answer #29 ExplanationThe correct answer is A: <10% of the European population currently meets the recommended physical activity guidelines.The American Heart Association, European Society of Cardiology, and World Health Organization all share the recommendation that adults should engage in 150 minutes per week of moderate-intensity physical activity or 75 minutes per week of vigorous-intensity activity. They recognize that additional health benefits may be garnered from incremental increases to 300 minutes per week of moderate intensity activity or 150 minutes per week of vigorous intensity activity, with a recommendation to include both aerobic and muscular strength training activities.According to the WHO, physical inactivity is the 4th leading cause of death in the world. The statistics regarding physical inactivity are staggering. Recent studies have shown that <10% of the European population meets the minimum recommended levels of physical activity. Similarly, ¼ adults and ¾ adolescents (aged 11-17) do not currently meet the global recommendations for physical activity. The World Health Organization has created a Global Action Plan on Physical Activity 2018-2030 with the goal to achieve a 15% relative reduction in the global prevalence of physical inactivity by 2030.Society level interventions to increase physical activity have been proposed including school-based activity programs, improved accessibility of exercise facilities across the socioeconomic spectrum, and governmental consideration of physical activity when designing cities (i.e. including pedestrian and cycling lanes). Other policy suggestions with varying levels of evidence include focused media campaigns, economic incentives, targeting labeling of physical activity opportunities, and work-place wellness programs.Main TakeawayDespite growing awareness of the health consequences of sedentary behavior, fewer than 10% of adults currently meet the minimum recommended quantity of physical activity. Public health leaders may continue to consider novel legislative initiatives to augment physical activity on a societal level with architectural design and financial incentives.Guideline Loc.Section 5.2 CardioNerds Decipher the Guidelines - 2021 ESC Prevention SeriesCardioNerds Episode PageCardioNerds AcademyCardionerds Healy Honor RollCardioNerds Journal ClubSubscribe to The Heartbeat Newsletter!Check out CardioNerds SWAG!Become a CardioNerds Patron!

Question #23 Mrs. Hart is a 63-year-old woman with a history of non-ischemic cardiomyopathy and heart failure with reduced ejection fraction (LVEF 20-25%) presenting with 5 days of worsening dyspnea and orthopnea.   At home, she takes carvedilol 12.5mg BID, sacubitril-valsartan 24-46mg BID, empagliflozin 10mg daily, and furosemide 40mg daily.   On admission, her exam revealed a blood pressure of 111/79 mmHg, HR 80 bpm, and SpO2 94%. Her cardiovascular exam was significant for a regular rate and rhythm with an audible S3, JVD to 13 cm H2O, bilateral lower extremity pitting edema with warm extremities and 2+ pulses throughout.  What initial dose of diuretics would you give her? A Continue home Furosemide 40 mg PO B Start Metolazone 5 mg PO C Start Lasix 100 mg IV D Start Spironolactone Answer #23 Explanation The correct answer is C – start Furosemide 100 mg IV. This is the most appropriate choice because patients with HF admitted with evidence of significant fluid overload should be promptly treated with intravenous loop diuretics to improve symptoms and reduce morbidity (Class 1, LOE B-NR). Intravenous loop diuretic therapy provides the most rapid and effective treatment for signs and symptoms of congestion. Titration of diuretics has been described in multiple recent trials of patients hospitalized with HF, often initiated with at least 2 times the daily home diuretic dose (mg to mg) administered intravenously. Titration to achieve effective diuresis may require doubling of initial doses, adding a thiazide diuretic, or adding an MRA that has diuretic effects in addition to its cardiovascular benefits. Choice A is incorrect as continuing oral loop diuretics is not recommended for acute decongestion. Moreover, Ms. Hart has become congested despite her home, oral diuretic regimen. Choice B and D are incorrect as starting a thiazide diuretic or a mineralocorticoid receptor antagonist are not first-line therapy for acute HF. Rather, in patients hospitalized with HF when diuresis is inadequate to relieve symptoms and signs of congestion, it is reasonable to intensify the diuretic regimen using either: a.

Pearls and Quotes - Atrial Fibrillation: Situational Assessment of Stroke and Bleeding Risk In patients with persistent atrial fibrillation with tachycardia induced cardiomyopathy, timely restoration of normal rhythm is important. In patients not on established oral anticoagulation one option is to wait 3 weeks on oral anticoagulation prior to considering cardioversion. Another option is to pursue TEE prior to cardioversion as TEE is currently the gold standard imaging modality to exclude a LAA thrombus. Following cardioversion (chemical or electrical), anticoagulation must not be interrupted for 4 weeks due to atrial stunning. This is especially true for patients who have been in atrial fibrillation for an extended period of time. Individualizing assessment of stroke and bleeding risk is imperative when determining perioperative anticoagulation (AC) management. ACC has a helpful app (ManageAnticoag App) to make this easier. When considering AC in triggered atrial fibrillation (e.g., pneumonia, sepsis), it is important to consider the substrate that made the patient susceptible to developing atrial fibrillation. AC is favored in patients with high CHA2DS2-VAsC score and many traditional risk factors for atrial fibrillation as they are at high risk for future development of atrial fibrillation. Atrial fibrillation is a marker of poor outcomes in patients who have undergone coronary artery bypass graft (CABG) surgery. It is unclear if patients should be started on long-term AC for new onset atrial fibrillation after CABG regardless of risk factors. This is currently being investigated in the PACES trial. Notes - Atrial Fibrillation: Situational Assessment of Stroke and Bleeding Risk How do we choose an imaging modality for excluding LAA thrombus exclusion prior to cardioversion? TEE is the gold standard. It also provides other information that is important for management of atrial fibrillation (e.g. LA size/volume, presence/degree of mitral regurgitation/stenosis, ejection fraction). Gated cardiac CTA may have a growing role for evaluation of LAA thrombus. What is the data behind the recommendation for uninterrupted AC following cardioversion and what is atrial stunning? All patients should be anticoagulated for four weeks after cardioversion,
