Insights
Acute coronary syndromes (ACS) have a poorly understood epidemiology, especially unstable angina. The 1-month mortality rate for ACS is approximately 50%, rising significantly with age.
Area of Science:
- Cardiology
- Epidemiology
- Public Health
Context:
- Acute coronary syndromes (ACS) present distinct epidemiological profiles compared to myocardial infarction, particularly when considering all cases versus only hospitalized patients.
- A significant number of ACS cases are not captured in hospital data due to pre-hospital mortality.
- Specific epidemiological data for unstable angina, a key component of ACS, remain scarce.
Purpose:
- To highlight the epidemiological differences between overall acute coronary syndromes and hospitalized patients.
- To underscore the lack of comprehensive data on unstable angina epidemiology.
- To present current incidence and lethality rates for ACS in France.
Summary:
- The annual incidence of ACS in France exceeds 280 per 100,000 men and 60 per 100,000 women.
- The overall 1-month lethality rate for ACS is approximately 50%.
- Lethality rates for ACS increase markedly with advancing age.
Impact:
- Emphasizes the critical need for improved data collection on ACS, particularly unstable angina.
- Highlights the substantial public health burden of ACS, indicated by high incidence and mortality rates.
- Informs targeted public health interventions and clinical management strategies for ACS, especially in older populations.
Abstract:
As for myocardial infarction, the epidemiology of acute coronary syndromes is very different according to whether it concerns hospitalized patients only or acute coronary syndromes as a whole: many patients die before any medical intervention. The epidemiology of acute coronary syndromes is not well known since we have almost no specific data regarding unstable angina. The annual incidence of acute coronary syndromes in France is greater than 280 per 100,000 men and 60 per 100,000 women. The 1-month lethality rate is about 50%, increasing sharply with age.
