Penetrating cardiac injuries: a population-based study

Area of Science:

• Trauma Surgery
• Emergency Medicine
• Public Health

Background:

• Penetrating cardiac injuries have variable reported survival rates due to reliance on hospital-based data.
• Local trauma system variations influence reported outcomes for cardiac trauma.

Purpose of the Study:

• To determine population-based and hospital-based survival rates for penetrating cardiac injuries.
• To provide a more accurate assessment of outcomes for penetrating cardiac injuries.

Main Methods:

• Retrospective cohort analysis of 20,181 trauma admissions and 6,492 medical examiner reports over 7 years.
• Meta-analysis comparing study survival rates with existing population-based reports.
• Inclusion of all penetrating cardiac injuries within the study period.

Main Results:

• Identified 212 penetrating cardiac injuries, with an incidence of 1 per 100,000 man-years.
• Overall population survival rate was 19.3% (41/212); gunshot wounds: 9.7% (12/123), stab wounds: 32.6% (29/89).
• Hospital survival rate was 42.7% (41/96); gunshot wounds: 29.3% (12/41), stab wounds: 52.7% (29/55).

Conclusions:

• Population-based data indicate minimal improvement in survival rates for penetrating cardiac injuries.
• Distinguishing between gunshot and stab wounds is crucial for understanding survival outcomes.
