Coronary arteriograms and myocardial scintigrams in the electrocardiographic syndrome of septal fibrosis.

Coronary artery disease (CAD) and myocardial perfusion were assessed by arteriograms and scintigrams (Technetium-99 microspheres alone or combined with Iodine-131 albumin macroaggregates) in 178 angina pectoris patients with and without the electrocardiographic (ECG) syndrome of septal fibrosis and with greater than or equal to 70% obstruction in one or more coronary arteries. The ECGs of 96 patients without angiographic evidence of obstructive CAD were also examined for the ECG syndrome of septal fibrosis. Patients with the ECG syndrome of septal fibrosis have significantly higher incidences of positive exercise stress test, of greater than or equal to 70% narrowing of the proximal left anterior descending (LAD) artery, of severe proximal LAD disease, and of more extensive left ventricular hypoperfusion than patients without the ECG syndrome. The fact that only 4% of patients without obstructive CAD have the ECG syndrome of septal fibrosis indicates the usefulness of the syndrome in identifying a subset of angina pectoris patients with advanced CAD of the proximal LAD and diffuse left ventricular hypoperfusion.

The mural left anterior descending coronary artery, strenuous exercise and sudden death.

Postmortem studies of three ostensibly healthy persons whose unheralded death occurred incidental to strenuous exercise revealed an obstructed but mural left anterior descending (LAD) artery, diminished vascularity to the posterior left ventricle and ventricular septum, and morphologic evidence of patchy, ischemic necrosis of the ventricular septum in different stages of healing. Although mural coronary arteries are considered a normal anatomic variant, our observations, coupled with reported clinical studies, strongly suggest that systolic constriction of the LAD artery may precipitate death in selected subjects.

Clinical and pathologic features of obstructive disease in the predominant right and left coronary circulations in man.

The clinical features and the location and severity of obstructive coronary artery disease are contrasted in 98 patients with predominant left and 99 patients with predominant right coronary circulations. A significantly higher incidence of ventricular conduction disturbances and a greater incidence and severity of obstructive coronary artery disease (greater than or equal to 70% cross-sectional narrowing in the proximal left anterior descending, circumflex and right coronary arteries and their major branches) distinguish the predominant left from the predominant right coronary circulation. The results suggest an anatomically disadvantaged status for the predominant left compared with the predominant right coronary circulations with respect to ventricular conduction disturbances and to coronary atherogenesis in man.
