Dependencies
What this concept builds on and what it makes possible — derived from the atlas’s dependency, causal and structural relations, not from every related edge.
Foundations · builds on
Coronary AtherosclerosiscausesMyocardial IschemiaEstablished
Open Coronary Atherosclerosis →
Coronary Atherosclerosis causes Myocardial Ischemia.
Mechanism: Plaques narrow the coronary lumen and restrict blood flow, so oxygen delivery falls short of myocardial demand.
Enables · leads to
Myocardial IschemiacausesAngina PectorisEstablished
Myocardial Ischemia causes Angina Pectoris.
Mechanism: Reversible oxygen deprivation of the myocardium triggers the chest pain perceived as angina.
Myocardial IschemiacausesMyocardial InfarctionEstablished
Myocardial Ischemia causes Myocardial Infarction.
Mechanism: If ischemia persists, myocytes are irreversibly injured and die, producing an infarct.
Structural role & consequence
Interpreted from the current atlas graph — what the connections mean, not just how many there are.
Directly enables 2 concepts; following enables/causes relations, 3 concepts are downstream across 1 discipline.
structural · Follows only enables/causes dependency edges — not general relatedness.
Currently dark in the atlas: no key date stored · 3 of 3 of its relations lack claim-level evidence.
atlas representation · Describes the current Thinking OS representation, not the state of the world.
Builds on 1 foundation (requires / depends-on / derived-from / emerges-from).
structural · Structural graph analysis — not a claim of importance, causation or history.
All 3 of its relationships stay within its own discipline — a field-specific concept in the current atlas.
structural · Structural graph analysis — not a claim of importance, causation or history.

Strengths & constraints
Constraints
- Evidence coverage currently thin in the atlas — few of its relationships carry claim-level evidence. atlas representation
- No dated history stored — the atlas records no key date for this concept. atlas representation
Conditions
- Its dependency reading rests on 1 foundation relation. structural
- Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural

Seen through each discipline
How this concept sits in each of its fields — derived from its real connections in the graph, not asserted.
Through this lens it connects to Myocardial Infarction, Coronary Atherosclerosis and Angina Pectoris.
