the invention is in section a - human needs in health; rescue; recreation, section a61 - medical or veterinary science; hygiene in field a61d - veterinary instruments, implements, tools or methods and in part 99/00 - material not covered by the other groups in this subclass. detection of signs of venous congestion and cardiac remodeling in patients with mitral valve myxomatous disease by echocardiographic examination by measuring left atrial to aortic artery, wave measurement, wave ratio and isovolumetric relaxation time and by the relation of the wave and the wave e '. The chest x-ray is a fast-performing exam and can be performed by less experienced professionals. For each echocardiographic measurement that indicates congestion, a formulary that estimates it using the chest radiographic measurements was made. the formula were: ae: ao = 0.03 * (vhs) + 0.014 * (ae) + 0.27 * (ae: vcc), with coefficient of determination (r 2) of 0.97; for the wave measure e = 16.89 * (ae) + 14.88 * (ae: ao), for the ratio e: triv = 0.76 * (ae) and ratio e: e '= 0.60 * ( vhs) + 1.61 * (ae: vcc). r 2 were 0.92, 0.61 and 0.92 respectively. Using these formulas, it is possible to estimate venous congestion and cardiac remodeling in dmvm dogs and to start early, without the need for echocardiographic examination, to treat these patients.
