[Clinical electrocardiographic and coronary angiographic findings in 200 cases of ischemic cardiopathies].

A correlative analysis of clinical, electro and angiographic data was carried on, in a series of 200 cases of ischemic heart disease. The possible pathophysiological mechanisms of coronary insufficiency in cases with normal arteriograms, are briefly discussed. Based upon the statiscal results, it can be concluded that there is a close relationship between angiographic findings, and the clinical and electrocardiographic data suggestive of coronary insufficiency.

[Hemodynamic consequences of ventriculography in ischemic cardiopathy].

A series of 13 cases of ischemic heart disease, proved by coronary angiography, were submitted to ventriculography in order to study the hemodynamic consequences of the injection of the contrast material. The parameters used to evaluate the ventricular function were the end diastolic pressure, the dp/dt, the VEC and the V. max. A close relationship was observed between the hemodynamic changes secondary to the ventriculography and the degree of coronary involvement. The behaviour of the end diastolic pressure postventriculography can be considered a reliable parameter for evaluating the ventricular functional capacity. Contrariwise, the minimal changes of thee V. max. makes it of doubtful valve.

[Value of the electrocardiogram to predict the pattern of left ventricular contraction in ischemic cardiopathy].

A correlative electrocardiographic and ventriculographic study was performed in a series of 100 patients with clinical and electrocardiographic diagnosis of ischemic heart disease. The analysis was focused on the possibility of predicting ventricular contraction pattern (VCP) disturbances, through electrocardiographic signs of coronary insufficiency. Two main groups were separated on the basis of the presence of necrosis. There were 66 cases with necrosis, and 34 without it. The type of VCP was calssified in accordance with the criterion of Herman et al. in: asyneresis, akinesis and dyskininesis. The degree of coronary narrowing was arbitrarily evalued as less than 50%, between 50 and 75%, and over 75% of the lumen.

[Left ventricular hypertrophy. Correlation of ventriculographic findings in ischemic cardiopathy].

In order to analyze the angiographic characteristics associated with left ventricular hypertrophy in patients with coronary insufficiency, the left ventriculography was used to calculate the ventricular volumes, the ejection fraction (EF) and the ventricular mass (LVM) in 31 patients with clinical diagnosis of ischemic heart disease. Patients were divided into three groups: A) Those with normal coronaries and (EF), B) Those with coronary lesion and EF greater than 50% and C) Those with coronary lesions and EF less than 50%. The following results were obtained for the telediastolic volume (ml/m2), the EF (%) and the LUM (g/m2): Group A = 85 +/- 19, 73 +/- 7 and 41 +/- 13. Group B = 102 +/- 25, 61 +/- 8 and 50 +/- 9. Group C = 154 +/- 27, 39 /+- 7 and 74 +/- 17 respectively. Comparing the FEV with the LVM in the patients studied, a negative correlation was found with an r index of -0.7894 (p less than or equal to 0.001). The correlation index for the diastolic volume and the LVM was r = 0.6806; and -0.6991 for the EF and the telediastolic volume. These findings suggest that hemodinamic changes, especially an increase in the ventricular volume and subsequently in the tension of the ventricular wall, act as a stimulus in initiating a metabolic chain leading to ventricular hypertrophy. This process is compensatory in the initial phases of the disease (groups A and B) but insufficient in the advanced stage (group C).

[Prolapse of the mitral valve].

Intending to find out which is the prevalence of mitral valvular prolapse in cases of ischemic cardiopathy with "normal" coronariography, a review was made of the coronary-ventriculographic studies at the I.N.C. archives, which showed as clinical diagnosis that of ischemic cardiopathy with "normal" coronaries. In the present studies we record 47 cases showing chest angina and/or electrocardiographic changes in rest or effort tests, compatible with myocardic ischemia and coronariography undoubtedly normal. We found 30 cases (63.8%) showing strong evidence of mitral prolapse in the left cineventriculography taken in right-front oblique position.
