New research reveals surprising outcomes in overdose-related cardiac arrests

People whose hearts suddenly stop due to a drug overdose are younger, have fewer health problems and are more likely to survive with fewer neurological problems than those whose out-of-hospital cardiac arrests are due to other causes, 新的研究表明.

的 研究, 周三发表在《沙巴体育平台点击进入》上, found drug-related cardiac arrests also were less likely to be witnessed by someone and less likely to have a shockable heart rhythm that could respond to a shock from a defibrillator.

"Many communities face ongoing challenges with increases in drug overdoses, 哪些倾向于影响年轻人, 健康的人口,该研究的主要作者Aditya C. 谢卡尔说 沙巴足球体育平台发布会上. Shekhar is a medical student at the Icahn School of Medicine at Mount Sinai in New York City. 鉴于最近与药物过量相关的死亡人数有所增加, there is immense public health interest to better understand these types of cardiac arrests and how to treat them."

心脏骤停是指心脏突然停止跳动. 大约350,每年有000例心脏骤停发生在医院外, 根据美国心脏协会. 的 majority of these are due to heart attacks or electrical issues with the heart, but opioid overdose-related cardiac arrests are a major cause of death for adults 25 to 64 years old.

People who survive cardiac arrests may have brain damage, internal organ damage and other problems.

Using data from the national Cardiac Arrest Registry to Enhance Survival, 或关心, 数据库, researchers compared out-of-hospital cardiac arrests from drug overdoses to those from other causes. Among 360,000 cardiac arrests from 2017 to 2021, 8% were caused by drug overdoses. Drug-related cardiac arrests included both intentional and accidental overdoses from medication, 合法和非法的毒品和酒精.

的 majority of people with drug-related cardiac arrests – about 95% – initially had a nonshockable heart rhythm, 也就是说除颤器对他不起作用, 相比之下，79%的心脏因其他原因停止跳动. Yet they were significantly more likely to survive and had better neurological outcomes.

When the first rhythm was shockable, the groups had similar survival rates.

People who had overdose-related cardiac arrests were twice as likely to return to independent living and perform daily living activities without assistance compared to those who had cardiac arrests due to other causes.

People who experienced overdose-related cardiac arrests were younger, with an average age of 39 compared to 64 for people whose hearts stopped for other reasons. 他们的健康状况也更少, 比如2型糖尿病, 高血压, 肾脏疾病, 心脏病, 呼吸道疾病, 高胆固醇或中风.

"We were surprised that survival rates and neurological outcomes were significantly better in patients with nonshockable heart rhythms from drug-related cardiac arrests, 即使在控制了年龄和其他因素之后,该研究的资深作者Dr. 瑞安一. 库特在沙巴足球体育平台稿中说. Coute is an assistant professor of emergency medicine at the University of Alabama-Birmingham Heersink School of Medicine.

"Our 研究 suggests that different causes of cardiac arrest have unique features and, 结果是, 他们的结果有不同的趋势吗. 的re may be a growing need to treat different causes of cardiac arrest with different techniques,他说.

的 analysis also showed only 1 in 5 drug-related cardiac arrests were witnessed by a bystander, 相比之下，近一半的人是由其他原因造成的.

Shekhar noted that receiving bystander 心肺复苏 can play a critical role in a person's chances for survival.

“当有人心脏骤停时, 他们的大脑缺氧, 脑细胞在几分钟内开始死亡,他说. "Performing 心肺复苏 has been shown to dramatically improve outcomes for cardiac arrest by helping get blood to the brain quickly."
