Coronary Collateral Blood Flow
Background. Although aspirin exerts beneficial antiplatelet activity in patients with coronary artery disease, cyclooxygenase blockade produced by aspirin causes a potentially deleterious effect by interrupting endothelial production of prostacyclin. Collateral vessels that develop in response to coronary occlusion display prominent endothelial cell proliferation and undergo vasoconstriction in...
متن کاملCollateral flow index to assess myocardial viability: Chugh's hypothesis revisited.
Viability: Chugh’s Hypothesis Revisited To the Editor: The article by Werner et al1 in the December 12, 2000, issue of Circulation provides further evidence that the collateral flow index can be used to quantify collaterals and correlates with the presence of preserved myocardial contractile function. This supports Chugh’s hypothesis, which was first put forward in 1997 and was published in the...
متن کاملCollateral-flow measurements in humans by myocardial contrast echocardiography: validation of coronary pressure-derived collateral-flow assessment.
AIMS Myocardial blood flow (MBF) is the gold standard to assess myocardial blood supply and, as recently shown, can be obtained by myocardial contrast echocardiography (MCE). The aims of this human study are (i) to test whether measurements of collateral-derived MBF by MCE are feasible during elective angioplasty and (ii) to validate the concept of pressure-derived collateral-flow assessment. ...
متن کاملEffect of platelet activation on coronary collateral blood flow.
BACKGROUND The platelet products thromboxane A2 and serotonin have been shown to cause constriction of well-developed coronary collateral vessels. This study was performed to determine whether intravascular platelet activation produced with platelet activating factor (PAF) can cause a decrease in coronary collateral blood flow. METHODS AND RESULTS Collateral vessel growth was induced by embol...
متن کاملEvaluation of procedure designed to enhance coronary collateral blood flow.
• The high incidence of coronary artery disease in man has prompted extensive research efforts in the direction of improving blood flow to the heart muscle. Attempts to achieve this goal have taken many forms and may be summarized as follows: (1) scarifying procedures designed to encourage the growth of new vascular channels into the heart from extracardiac sources; (2) retrograde perfusion of ...
