Summary

Coronary angiography is invasive and expensive, questioning its role as a first-line diagnostic tool. Its use should be reserved for cases with clear clinical benefit, like severe angina, to avoid unnecessary procedures.

Area of Science:

  • Cardiology
  • Diagnostic Imaging

Background:

  • Coronary angiography is frequently performed but remains invasive and costly.
  • Its role as a first-line diagnostic method requires critical evaluation.

Purpose of the Study:

  • To discuss the appropriate role of coronary angiography in diagnosing coronary atherosclerosis.
  • To evaluate the clinical benefit of routine versus selective use of coronary angiography.

Main Methods:

  • Review of the diagnostic capabilities and limitations of coronary angiography.
  • Analysis of prognostic indicators provided by the procedure.
  • Consideration of functional repercussions of coronary stenosis.

Main Results:

  • Coronary angiography definitively diagnoses coronary atherosclerosis and provides prognostic indicators (vessel disease).
  • It cannot precisely assess disease severity or functional impact of stenosis.
  • First-line use is justified mainly for patients with significant angina symptoms.

Conclusions:

  • Systematic, first-line coronary angiography may not offer obvious clinical benefit in all cases.
  • Decisions for myocardial revascularization should not solely rely on angiography findings.
  • Avoid the "oculostenotic reflex" by considering functional significance over anatomical "mapping" alone.
