Silent myocardial ischemia has emerged from a subject of mainly research interest to one with important clinical implications for practicing physicians. Although the pathophysiologic mechanisms responsible for the absence of pain are still not clear, it is apparent that episodes of silent myocardial ischemia are frequent and occur in many patients with coronary artery disease; episodes occur both in asymptomatic and symptomatic patients; episodes are detectable by various noninvasive and invasive techniques; and episodes appear to have important prognostic implications when combined with the extent of anatomic disease and degree of left ventricular dysfunction. It is expected the rapidly accumulating prognostic data, especially in patients after infarctions and patients with unstable angina, will have a profound effect on the way physicians treat their patients with coronary artery disease.

Excerpt To the editor: We describe here a family (husband, wife, and children) with asymmetric septal hypertrophy. To our knowledge, this is the first report of an entire family with this disorder....

To evaluate the association between serum cholesterol and triglyceride levels and angiographically determined coronary artery disease, two selected groups of 100 patients each were compared. The coronary artery disease group had significantly higher serum levels of both cholesterol and triglyceride. However, several types of analyses based on the quartile distribution of serum levels of cholesterol and triglyceride showed that the serum cholesterol level was more significantly associated with coronary artery disease than was the triglyceride level. This was especially true in relation to multivessel disease, the most severe form of coronary artery disease, and most marked in men. Association with coronary artery disease appeared to be continuous, rather than being related to any critical serum level, thus re-emphasizing the need to distinguish between desirable and average levels of serum cholesterol in countries with a high dietary intake of saturated fat.

Excerpt Previous attempts by our laboratory to diagnose coronary artery disease by means of single noninvasive measures have had only limited success. It has been our experience that abnormalities ...

Excerpt Angina Pectoris is a symptom complex originally described by Heberden some 200 years ago. Although his description of the pain has not really been improved on, its precise causation has rem...
