The number of hematopoietic stem cell transplants (HSCTs) performed in the United States and worldwide is increasing. Cardiac events have been well described in HSCT, and the incidence and type of cardiac events have not changed over recent decades. This study adds to the body of evidence in describing the incidence and type of cardiac events experienced by an allogeneic and autologous HSCT population at a single institution from 2012 to 2017. Sixty-five (9.8%) patients experienced cardiac events, including atrial arrhythmia (N = 39), acute heart failure (N = 9), acute coronary syndrome (N = 7), and new onset hypertension (N = 9), with a few instances of bradycardia, ventricular arrhythmia, pericardial effusion, and pericarditis. Our multivariable regression analysis identified age (older), creatinine (higher), and history of coronary artery disease to significantly correlate with risk of cardiac event (P = .005, P = .039, and P = .038, respectively). A subgroup analysis of those patients experiencing a cardiac event found pre-transplant atrial dilation by trans-thoracic echocardiogram to correlate with increased risk of atrial arrhythmia (33.8% vs. 9.7%; P = .03). Patients developing a CE had an increased risk of death within 1 year (11% vs. 32%; P < .001). We review our results in context of other important HSCT cardiac studies to illuminate the most relevant factors of medical history, laboratory data, and cardiac measurements that will identify patients at higher risk, allowing for intervention to improve HSCT outcomes.
