Temporal Association Between Vaping and Risk of Cardiac Events

Objective: To describe our early observations with sudden cardiac arrest (SCA) and sudden death (SD) in patients using vape products. Patients and Methods: A retrospective analysis of Mayo Clinic's Windland Smith Rice Genetic Heart Rhythm Clinic and Sudden Death Genomics Laboratory was performed on all SCA survivors and decedents who presented between January 1, 2007, and December 31, 2021, to identify patients/decedents with a history of vaping. Data abstraction included patient demographics, clinical characteristics, and documented use of vape products. Results: Among 144 SCA survivors and 360 SD victims, there were six individuals (1%; 3 females) with unexplained SCA (n=4) or SD (n=2) that was temporally associated with vaping use with a mean age at sentinel event of 23 +/- 5 years. The SCA survivors include a 19 -year -old male who was resuscitated from documented ventricular fibrillation 40 minutes after vaping and a 19 -year -old male who was resuscitated from ventricular fibrillation a few hours post vaping. The first SD victim was a 19 -year -old female with exercise-induced asthma who died in her sleep after vaping that evening. Autopsy results showed eosinophilic infiltrates in the lung tissue and death was attributed to bronchial asthma. The second vaping-associated death involved a 26 -year -old male whose autopsy attributed the death to acute respiratory distress syndrome. Conclusion: We have identified six young individuals with a history of vaping who experienced a near fatal episode or a tragic SD. Although larger cohort studies are needed to quantify the actual risk of SD, it seems prudent to sound an early warning about vaping's potential lethality.
