Sudden death and cocaine abuse

We read with great interest the results of the study by Lucena et al.(1) and present the following comments related to the paper. Lucena et al. presented a series of 21-cocaine-related sudden deaths (SD) showing two main structural abnormalities, cardiac hypertrophy and atherosclerotic coronary disease. Both abnormalities have been previously considered as a consequence of a chronic cocaine abuse, but could also be related to others cardiovascular risk factors, as admitted by Lucena et al.
