Discussion

This essay reveals the phasic nature of coronary blood flow in the microcirculation, highlighting the roles of myocardial compression and recoil.

Main finding: Coronary blood flow is not continuous but phasic, with significant contributions from myocardial dynamics.
Key evidence: During systole, forward flow occurs in coronary veins, while epicardial arteries show no forward flow to the left ventricle.
Approach: The essay critiques conventional models by emphasizing the role of myocardial compression and recoil during diastole.
Significance: Understanding these dynamics may alter the diagnosis of microcirculation disorders in heart failure with preserved ejection fraction.

Sniderman et al. (2025) studied this question.
