Survival rates and prehospital delay during myocardial infarction among black persons
Insights
This study found a 19% 2-week mortality rate in Black patients with coronary artery disease (CAD). Delayed hospital arrival, twice as long as in white populations, was a key factor. Public health campaigns should emphasize prompt care seeking.
Area of Science:
- Cardiology
- Public Health
- Health Disparities
Background:
- Coronary artery disease (CAD) affects diverse populations, but outcomes can vary.
- Understanding specific risk factors and healthcare access challenges in minority populations is crucial for targeted interventions.
Purpose of the Study:
- To investigate the 2-week mortality rate and associated factors in Black patients admitted to a Chicago municipal hospital.
- To compare symptom-to-hospital arrival times in this cohort with predominantly white populations.
Main Methods:
- A 12-month observational study of 111 consecutive Black patients admitted for CAD.
- Analysis of mortality rates, comorbidities (hypertension, diabetes), and time delays from symptom onset to hospital arrival.
Main Results:
- The 2-week mortality rate was 19%, with higher rates in women.
- Systemic hypertension (75%) and diabetes mellitus (33%) were prevalent but not significant mortality predictors.
- Symptom-to-arrival times were significantly prolonged compared to white populations (median twice as long, mean three times as long).
Conclusions:
- Black patients in this Chicago cohort experienced a high short-term mortality rate from CAD.
- Delayed healthcare-seeking behavior, influenced by prolonged symptom-to-arrival times, is a critical issue.
- Public health initiatives must focus on patient education regarding CAD symptoms and improving access to timely medical care for this population.
Abstract:
Over a 12-month period, a consecutive series of 111 black patients admitted to a municipal hospital in Chicago was studied. The 2-week mortality rate for the entire group was 19% (95% confidence intervals, 11.7 to 26.3), and the rate was twice as high for women as for men. A history of systemic hypertension was encountered in 75% of the patients, and diabetes mellitus was present in 33%, although they were not significant predictors of mortality within this group. The delay time from onset of symptoms to arrival at the hospital was markedly prolonged compared with studies of predominantly white populations--twice as long at the median and 3 times as long at the mean. Preventive campaigns aimed at this population should include educating patients on the symptoms of coronary artery disease and encouraging them to seek prompt medical care. Attention must also be given to eliminating obstacles to access to care in this group.
