This high incidence of Chlamydia only in coronary arteries diseased by atherosclerosis suggests an etiologic role for Chlamydia infection in the development of coronary atherosclerosis that should be further studied.

Patients with angiographic evidence of CAD or clinical MI do not show an increased frequency of the C677T transition in the MTHFR gene. Our findings do not support this polymorphism as a risk factor for CAD or MI in a predominantly white, well nourished population of unrestricted age.

We describe percutaneous, translumbar placement of a 14-Fr dialysis catheter into an ascending lumbar vein to achieve tip position in an enlarged azygos vein. The patient had thrombosis of all traditional vascular sites, as well as the inferior vena cava. This catheter functioned well for 7 months before fatal catheter-related infection developed.

Consistent with findings in male-dominated populations, a modest association of the ACE DD genotype with MI was found in women. The basis for this association requires further study.
