摘要:

Variations in serum concentration of the enzyme, glutamic oxalacetic transaminase, in 64 patients with rheumatic fever were studied. Elevations were noted in 17 of 26 patients with carditis of definite or questionable activity and transiently in one rheumatic subject with viral myocarditis. Except for one patient with polyarthritis and equivocal evidence of acute cardiac involvement, serum concentrations were normal during noncardiac rheumatic manifestations and inactive carditis. There was no relationship to temperature, sedimentation rate, white blood count or C-reactive protein. Intermittent necrosis of myocardial fibers probably leads to these increased serum transaminase concentrations.

摘要:

On the thoracic roentgenograms of patients with mitral stenosis, costophrenic septal lines are frequently seen. These lines are a sign of pulmonary venous hypertension. They were not seen in a representative group of patients with pulmonary arterial hypertension but without pulmonary venous hypertension.

摘要:

Two similar cases of unusual congenital anomalies of the heart are presented, in which there existed a direct communication between the left ventricle and the right auricle through a defect involving the membranous portion of the interventricular septum with defective formation of the medial leaflet of the tricuspid valve. Data obtained at catheterization, operative and postmortem findings are presented in each case. The differential diagnosis of this type of lesion is discussed.

摘要:

A case of cardioaortic fistula, due to rupture of an aneurysm of a sinus of Valsalva into the right ventricle, is described. This case was diagnosed in life and treated surgically one year later when the patient was admitted to hospital with bacterial endocarditis. The clinical features are discussed and the role of special methods of investigation in the diagnosis of the condition is defined. The importance of cardiac catheterization is stressed. The operative technique is described briefly. Following the patient's death from the uncontrolled infection an autopsy examination was carried out and the findings in the heart and small pulmonary vessels are given.

摘要:

When primary amyloid infiltrates the myocardium, there is a loss of distensibility and a resistance to contraction similar to that seen in constrictive pericarditis. The clinical similarity between these two entities has been noted previously on only a few occasions and only one previous case of amyloid has had catheterization studies. A case of amyloid of the heart is presented with catheterization studies and the reasons for the clinical and physiologic similarity to constrictive pericarditis are discussed.

摘要:

Phenylbutazone is a potent anti-inflammatory agent. It was effective in modifying or causing the resolution of superficial thrombophlebitis in the extremities of 132 patients in whom this condition had proven refractory or difficult to manage. The short course of treatment which proved necessary to accomplish this end, makes this drug a practical and relatively safe addition to the management of superficial vein inflammation.

摘要:

A method is described for obtaining true orthogonal components of the heart vector by measuring the differences in potential between resistor networks which are connected to the limbs and to the back. The values of the resistors in the networks are determined by solving equations into which the scalar coefficients for the limbs and for the back are inserted.

摘要:

Part I dealt with dynamic arrangements (Dock, Smith, Walter, Nickerson, Burger, v. Wittern) which could be treated approximately as single masses in the lower frequency range. It was shown that in addition to the cardiovascular forces sought, other undesired forces from the support were mixed in, seriously altering the record: especially for components in the important 4 to 8 cycles per second region. Second, emphasis was laid on the several meanings that could be assigned the displacement, velocity and acceleration (DVA) records, according to what dynamic aspect (motion, momentum or force) of the cardiovascular action they werereferred. It was explained that all direct-body and stiff-bed ballistocardiographic records were "compound", as they could not be referred to any one of these dynamical quantities.In part II, we will discuss the platform methods in detail, showing how the platform mass comes into the record. The arguments for and limitations of the various platform methods are considered, including the "shin-platform" and the very light pendular platforms now being tried.

摘要:

Two abnormal waves present in the ballistocardiograms of 100 cases of mitral stenosis are described and the abnormality is classified into five grades. Evidence is presented which indicates that the abnormal waves are a result of ejection from the right ventricle and that the degree of abnormality of the ballistocardiogram bears a close relationship to the mean pulmonary artery pressure in mitral stenosis.

摘要:

The motions of the thorax and of the shins were recorded by a technic which gives approximately the same size waves when a given force is applied to the thorax in each of three planes. Applied to a group of men and women under 30 years of age and another group of normals over 50, the variations in form and size of the ballistocardiographic forces in three planes were recorded. During expiration and as a result of aging, the lateral systolic wave, IJ, increases in size relative to the head-foot IJ. It is concluded that the classic head-foot ballistocardiogram yields inadequate information on the force liberated in systole, particularly in older men.
