Determinants of Collateral

Determinants of coronary collateral circulation in patients with coronary artery disease.

OBJECTIVE This study aims to identify possible determinants of coronary collaterals in patients with severe coronary artery disease. METHODS The current study has a retrospective cohort design. Seventy four patients with ≥90% stenosis or total occlusion of the left anterior descending artery (LAD) were enrolled; coronary collateral grades, high-sensitive C-reactive protein (hs-CRP), fibrinoge...

Some determinants of coronary collateral blood flow in the open-chest dog.

Determinants of preformed collateral vessels in the human heart without coronary artery disease.

BACKGROUND Coronary collaterals protect myocardium jeopardized by coronary artery disease (CAD). Promotion of collateral circulation is desirable before myocardial damage occurs. Therefore, determinants of collateral preformation in patients without CAD should be elucidated. METHODS In 106 patients undergoing coronary angiography who were free of coronary stenoses, a total of 39 clinical test...

Collateral Crises⇤

Short-term collateralized debt, private money, is efficient if agents are willing to lend without producing costly information about the collateral backing the debt. When the economy relies on such informationally-insensitive debt, firms with low quality collateral can borrow, generating a credit boom and an increase in output. Financial fragility is endogenous; it builds up over time as inform...

Collateral circulation.

BACKGROUND The collateral circulation plays a pivotal role in the pathophysiology of cerebral ischemia. Current knowledge of the collateral circulation remains sparse, largely because of prior limitations in methods for evaluation of these diminutive routes of cerebral blood flow. SUMMARY OF REVIEW Anatomic descriptions of the collateral circulation often focus on more proximal anastomoses at...
