CPR Survival Rate: "Dongyangin Have Lower Rates Than Westerners"

Research by University of Missouri Medical School Team
Discharge Survival Rate of East Asians 8% Lower Than Whites
Many Variables Including Sample Data... Difficult to Be Certain

A study has found that the success rate of cardiopulmonary resuscitation (CPR), an emergency procedure to save patients whose hearts have stopped, varies by race.

A research team led by Professor Paul S. Chan from the University of Missouri School of Medicine announced these findings on the 26th (local time) in the international journal Journal of the American Heart Association.

The team analyzed CPR and survival data of 279,000 white and Asian adults residing in the United States to reach their conclusions.

Cardiopulmonary resuscitation.

However, cardiac arrests occurring in nursing homes were excluded from the analysis, and Asians were grouped by regions including Korea, Japan, China, Malaysia, Cambodia, India, and Pakistan, covering Northeast Asia, Southeast Asia, and the Indian subcontinent.

The analysis showed that while the rate of receiving CPR was similar for both Asians and Westerners at about 42%, survival rates differed significantly. Asians had approximately 8% lower discharge survival rates compared to whites, and the probability of having a favorable neurological status was 15% lower.

Black and Hispanic individuals had significantly lower rates of bystander CPR compared to whites.

On the other hand, the notable point in this study is that Asians received CPR at levels comparable to whites, but survival rates still differed.

The research team pointed out that 95% of the data used in the study were from whites and 5% from Asians, indicating a quantitative imbalance in the sample data.

Additionally, variables such as the average age of Asians experiencing cardiac arrest (67 years) being higher than that of Westerners (62 years), a higher proportion of females among Asians (36%) compared to Westerners (34%), and a slightly lower rate of rhythm restoration through automated external defibrillator use (19% for Asians vs. 22% for Westerners) were also noted.

Therefore, the research team could not determine whether these results were due to socioeconomic status differences by race or biological differences. They emphasized the need for follow-up studies by dividing Asians into more precise subgroups for further analysis.
