[Comparative characteristics of the physical, x-ray and hemodynamic data in assessing heart failure in myocardial infarct].
The physical and X-ray findings in 103 patients with acute myocardial infarction were compared with the value of left-ventricular filling pressure (LVFP). The LVFP was determined from the level of end diastolic pressure in the pulmonary artery determined by means of a balloon catheter. On the whole, the congruence was revealed between the X-ray findings and the LVFP. A still more definite picture may be obtained of the LVFP value if the results of physical examination are considered in addition to the X-ray data. At the same time, a disparity arises in some cases between the information obtained by means of catheterization of the pulmonary artery on the one hand and the physical and X-ray methods on the other. This must be borne in mind in applying intensive therapeutic measures, e. g. in cases with acute left-ventricular insufficiency, because erroneous therapeutic tactics may be chosen due to "post-therapeutic delay" of the physical and X-ray symptoms.
