    Abstract:
    The authors reviewed 1474 consecutive selective coronary arteriograms performed on patients with suspected coronary insufficiency for the diagnosis of obstructive coronary disease and found 281 (19.1%) cases of apparently normal coronary arteries. These patients presented mean age of 47 +/- 10 years; they were 135 (48%) males and 146 (52%) females. The objective of this study was to obtain the hemodynamic profile of these patients for the following parameters: a) aortic and left ventricular pressures; b) volumes, ejection fraction, segmentary contraction, wall thickness and mass of left ventricle; c) morphology, mobility and competence of the mitral valve. Eight groups of patients were selected: 1) without hemodynamic alterations - 18.9%; 2) with systemic arterial hypertension - 48.7%; 3) with abnormal myocardial contraction - 16.7%; 4) with idiopathic left ventricular hypertrophy - 6.4%; 5) with mitral valve prolapse - 2.5%; 7) with myocardial bridge of the left anterior descending coronary artery - 1.8%; 8) with coronary arterial microfistula of the left ventricle - 0.4%. It is desirable to determine before situations of cardiac emergencies, whether provoked ischemia, as detected by noninvasive stress testing, is present before the performing coronary arteriography in patients, specially females, with systemic arterial hypertension, left ventricular hypertrophy, disorders of ventricular contraction or mitral valve prolapse.
