Cardiovascular Disease in Acute Cocaine Compared to Acute Fentanyl Intoxication Deaths.

Abstract: Cocaine is the most common stimulant drug that causes death in Connecticut. Unlike opioid intoxication deaths, which largely correlate with dose/concentration, cocaine deaths occur more idiosyncratically, with mechanisms of death often related to underlying cardiovascular disease. We examined 78 sole acute cocaine and 306 sole acute fentanyl intoxication deaths to assess their association with cardiovascular disease. In the cocaine cohort, 87% (68/78) had atherosclerotic and/or hypertensive cardiovascular disease while 40% (122/306) in the fentanyl cohort did. Cocaine was detected in 40% of all accidental drug intoxication deaths, 41% of all accidental drug intoxication deaths involving fentanyl, and 37% of all drug intoxication deaths involving heroin. The relatively low number of sole cocaine deaths compared to the much higher proportion of cocaine/opioid deaths may be explained by the synergistic effects encountered in many mixed drug intoxications, the contributory role of cardiovascular disease in sole cocaine deaths, and/or the increased prevalence and potency of fentanyl. The high number of sole cocaine deaths in which the decedents had co-existing heart disease compared to those from sole fentanyl deaths (P < 0.001) suggests that heart disease plays a mechanistic role in sole cocaine deaths, whereas the potency of fentanyl is the dominant mechanism in fentanyl deaths.
