CardioNerds co-founder Dr. Amit Goyal and episode leads Dr. Jaya Kanduri (FIT Ambassador from Cornell University) and Dr. Jenna Skowronski (FIT Ambassador from UPMC) discuss Complications of acute myocardial infarction with expert faculty Dr. Jeffrey Geske. They discuss various complications of acute MI such as cardiogenic shock, bradyarrythmias, left ventricular outflow tract obstruction, ruptures (papillary muscle rupture, VSD, free wall rupture), and more. Show notes were drafted by Dr. Jaya Kanduri. Audio editing by CardioNerds Academy Intern, student doctor Tina Reddy. The CardioNerds Beyond the Boards Series was inspired by the Mayo Clinic Cardiovascular Board Review Course and designed in collaboration with the course directors Dr. Amy Pollak, Dr. Jeffrey Geske, and Dr. Michael Cullen.

Pearls and Quotes - Complications of Acute Myocardial Infarction Sinus tachycardia is a “harbinger of doom”! The triad for RV infarction includes hypotension, elevated JVP, and clear lungs. These patients are preload dependent and may need fluid resuscitation despite having an elevated JVP. Bradyarrythmias in inferior MIs are frequently vagally mediated. The focus should be on medical management before committing to a temporary transvenous pacemaker, such as reperfusion, maintaining RV preload and inotropy, avoiding hypoxia, and considering RV-specific mechanical circulator support (MCS). Worsening hypotension with inotropic agents (e.g., dobutamine, epinephrine, dopamine, norepinephrine) after a large anterior-apical MI should raise suspicion for dynamic left ventricular outflow tract obstruction due to compensatory hyperdynamic basal segments. The myocardium after a late presentation MI is as “mushy as mashed potatoes”! Need to look out for papillary muscle rupture, VSD, and free wall rupture as potential complications. Papillary muscle rupture can occur with non-transmural infarcts, and often presents with flash pulmonary edema. VSDs will have a harsh systolic murmur and are less likely to present with pulmonary congestion. Free wall rupture can present as a PEA arrest. All of these complications require urgent confirmation on imaging and early involvement of surgical teams. Notes - Complications of Acute Myocardial Infarction How should we approach cardiogenic shock (CS) in acute myocardial infarction (AMI)? Only 10% of AMI patients present with CS, but CS accounts for up to 70-80% of mortality associated with AMI, usually due to extensive LV infarction with ensuing pump failure. Physical examSinus tachycardia is considered a “harbinger of doom”, when the body compensates for low cardiac output by ramping up the heart rateThe presence of sinus tachycardia and low pulse and/or blood pressure in a patient with a large anterior MI should raise suspicion for cardiogenic shockBe wary of giving IV beta blockers in this situation as negative inotropes can precipitate cardiogenic shock (Commit Trial) When interpreting a patient’s blood pressure in the acute setting, it is helpful to know their baseline blood pressure and if they have a significant history of hypertension. Patients <75 years of age with CS have improved survival at 6 months and at 1 year with early revascularization (SHOCK trial) Mechanical circulatory supportIntra-aortic balloon pump (IABP)No mortality benefit with IABP use in CS at 30 days and at 1 year (IABP-SHOCK II trial)ACC/AHA guidelines give IABP a class IIa recommendation for medically refractory AMI-CS in the USA, whereas the ESC guidelines give it a class III recommendation.Percutaneous left ventricular assist device (Impella)No difference in mortality between IABP or Impella use after 30 days or 6 months (IMPRESS trial)Howev...
