CardioNerds (Amit Goyal & Daniel Ambinder) join UCSF cardiology fellows (Emily Cedarbaum, Matt Durstenfeld, and Ben Kelemen) for some fun in San Francisco! They discuss a informative case of ST-segment elevation (STEMI) due to coronary vasospasm. Dr. Binh An Phan provides the E-CPR and program director Dr. Atif Qasim provides a message for applicants. Episode notes were developed by Johns Hopkins internal medicine resident Evelyn Song with mentorship from University of Maryland cardiology fellow Karan Desai.

The CardioNerds Cardiology Case Reports series shines light on the hidden curriculum of medical storytelling. We learn together while discussing fascinating cases in this fun, engaging, and educational format. Each episode ends with an “Expert CardioNerd Perspectives & Review” (E-CPR) for a nuanced teaching from a content expert. We truly believe that hearing about a patient is the singular theme that unifies everyone at every level, from the student to the professor emeritus.
We are teaming up with the ACC FIT Section to use the #CNCR episodes to showcase CV education across the country in the era of virtual recruitment. As part of the recruitment series, each episode features fellows from a given program discussing and teaching about an interesting case as well as sharing what makes their hearts flutter about their fellowship training. The case discussion is followed by both an E-CPR segment and a message from the program director.

Patient Summary
A man in his mid-50s with alcohol use disorder, cirrhosis, atrial fibrillation, and alpha thalassemia complicated by iron overload presented with hematemesis. He was tachycardic and hypotensive. Labs were notable for Hgb 8.1 (baseline of 10.2), INR 1.3, lactate 4.2, and ferritin 4660. He was started on IV PPI and octreotide. Course was complicated initially by Afib with RVR with hypotension. Subsequently, the patient developed unstable VT requiring CPR. Post-code EKG showed inferolateral ST elevations. Troponin-I rose from 19 to 225 and his pressor requirement continued to increase despite resolution of his GIB. TTE showed LVEF 42% with new inferolateral wall motion abnormalities, normal RV systolic function, severe mitral regurgitation, and small pericardial effusion. After treatment of his GIB by IR and GI, he underwent an urgent LHC which showed 30% stenosis in proximal LAD, 70% in LADD2, and 95% in distal RCA. Coronary spasm was noted in all vessels. Intracoronary nitroglycerin and nicardipine were administered with significant improvement in spasm and resolution of STE on EKG. Vasopressors were quickly weaned off after. He was eventually stabilized, extubated, and started on an oral nitrate and calcium channel blocker. Repeat TTE showed normalized systolic function without any wall motion abnormalities.

The CardioNerds 5! – 5 major takeaways from the #CNCR case
What are the cardiac manifestations of hemochromatosis? Cardiac hemochromatosis encompasses cardiac dysfunction from either primary or secondary hemochromatosis. Initially, hemochromatosis leads to diastolic dysfunction and arrhythmias. In later stages, it can lead to dilated cardiomyopathy. Diagnosis of iron overload is established by elevated transferrin saturation (>55%) and elevated serum ferritin (>300 ng/mL). Genetic testing for mutations in the HFE gene should ...
