Altered arterial connective tissue in racing greyhound dogs.
Vascular collagen and elastin contents and the ratio of collagen/elastin (C/E) were studied in racing greyhound dogs, a breed which exhibits increased cardiac output. As compared to mongrel dogs, vascular C/E was lower, suggesting a greater distensibility of vessels as an adaptive response to hemodynamic stress.
