Key result

A coronary index assessing the site, severity, and number of lesions significantly predicted survival over 5 years, with an index of 25% or less identifying a high-risk group.

Why the study?

Does a coronary index based on arteriography predict mortality in medically treated patients with coronary artery disease?

Population

1050 medically treated patients with coronary artery disease who did not undergo surgery, UK residents…

Implication

Supports lesion-based risk stratification in medically managed CAD; hypothesis-generating pending validation in contemporary cohorts.

Key Points

  • This research aims to evaluate the prognostic significance of a coronary index related to coronary artery disease severity and patient survival.
  • Follow-up of 1050 medically treated patients over ten years.
  • Mortality rates were analyzed, observing survival across different quartiles of a coronary index.
  • Survival curves were generated to assess differences among risk groups.
  • Overall mortality rate was 6.3% during the follow-up period.
  • 68% of deaths occurred within the first year, and 97% within the first five years.
  • Patients with a coronary index of 25% or less were identified as a high-risk group, further impacted by left ventricular abnormalities.

Structured PICO

Does a coronary index based on arteriography predict mortality in medically treated patients with coronary artery disease?

Population
1050 medically treated patients with coronary artery disease who did not undergo surgery, UK residents attending a single hospital.

Intervention
Calculation of a coronary index of severity based on the site, severity, and number of all lesions on coronary arteriography.
O
Outcome
Overall mortality at 5 and 10 years follow-up.hard clinical

A comprehensive coronary angiographic index incorporating the site, severity, and number of lesions strongly predicts 5-year survival in medically treated patients with coronary artery disease.

Limitations

  • Ejection fraction was not routinely measured and so has not been included in this analysis.

Cite This Study

R Balcon (1980) conducted a cohort in Coronary artery disease (n=1,050). Coronary index (severity of coronary artery disease) vs. Different quartiles of the coronary index was evaluated on Survival / mortality. A coronary index assessing the site, severity, and number of lesions significantly predicted survival over 5 years, with an index of 25% or less identifying a high-risk group.
