Autor: H. E. Garner, K. S. Rugh, R. D. Sarazan, D. O. Williams, C. R. Ross, R. B. Boatwright, D. M. Griggs

Publikováno v: American Journal of Physiology-Heart and Circulatory Physiology. 270:H1893-H1904

Adult-grade ponies were surgically instrumented with a Doppler flow probe and pneumatic cuff occluder on the left anterior descending coronary artery (LAD), sonomicrometry crystals and intraventricular micromanometer in the left ventricle, and cathet

Autor: C. R. Ross, D. M. Griggs, R. D. Sarazan, H. E. Garner, D. O. Williams, R. B. Boatwright, K. S. Rugh

Publikováno v: American Journal of Physiology-Heart and Circulatory Physiology. 263:H1145-H1153

Coronary collateral growth was stimulated in chronically instrumented conscious ponies by a previously validated intermittent coronary occlusion method. Changes in regional myocardial function (sonomicrometry) and reactive hyperemia (Doppler method)

Disuse inhibition of newly functional coronary collateral circulation in ponies

Autor: C. R. Ross, R. D. Sarazan, H. E. Garner, K. S. Rugh, R. B. Boatwright, D. O. Williams, D. M. Griggs

Publikováno v: American Journal of Physiology-Heart and Circulatory Physiology. 262:H385-H390

We evaluated the loss of coronary collateral function in the absence of stimulation (disuse inhibition) by doubling the interval between successive left anterior descending coronary artery (LAD) occlusions in ponies in which collateral function initi

Effects of coronary occlusion duration on reactive hyperemia in conscious dogs and ponies

Autor: R. D. Sarazan, H. E. Garner, Dean Franklin, D. M. Griggs, G. F. Krause

Publikováno v: American Journal of Physiology-Heart and Circulatory Physiology. 261:H768-H773

Coronary reactive hyperemia duration (RHD) and coronary blood flow debt repayment (BFDR) were compared in conscious dogs and ponies instrumented with coronary artery Doppler flow probes and pneumatic occluders. Additional ponies were instrumented wit

Myocardial blood flow, metabolism, and function with repeated brief coronary occlusions in conscious ponies

Autor: K. S. Rugh, D. M. Griggs, H. E. Garner, D. O. Williams, R. B. Boatwright

Publikováno v: American Journal of Physiology-Heart and Circulatory Physiology. 260:H100-H109

Studies were performed in the conscious pony instrumented with a Doppler flow probe and hydraulic occluder on the left anterior descending coronary artery (LAD), sonomicrometry crystals and intraventricular micromanometer in the left ventricle, and c

Transmural changes in porcine and canine hearts after circumflex artery occlusion

Autor: K. H. McDonough, D. M. Griggs, R. B. Dunn

Publikováno v: American Journal of Physiology-Heart and Circulatory Physiology. 246:H601-H607

The distribution of the coronary collateral circulation is an important determinant of the myocardial response to acute coronary artery occlusion. The dog shows an unequal response across the ventricular wall, whereas the pig seems to have more unifo

Ventricular filling pressure as a determinant of coronary blood flow during ischemia

Autor: D. M. Griggs, R. B. Dunn

Publikováno v: American Journal of Physiology-Heart and Circulatory Physiology. 244:H429-H436

The role of ventricular filling pressure (VFP) as a determinant of coronary blood flow (CBF) in the acutely ischemic ventricle was examined in the open-chest dog under conditions of a reduced, constant coronary artery pressure and an unstable VFP. Bl

High energy phosphate stores and lactate levels in different layers of the canine left ventricle during reactive hyperemia

Autor: D M Griggs, K M McDonough, Robert B. Dunn

Publikováno v: Circulation research. 44(6)

To study postischemic recovery of myocardial energy metabolism in relation to the reactive hyperemic response, the tissue levels of creatine phosphate (CP), adenosine triphosphate (ATP), and lactate were estimated in the outer, middle, and inner laye
