Atrial Septal Defect of the Ostium Secundum Type in A 101-Year-Old Patient.

The patient was a 101-year-old woman whose chief complaints were difficulty of breathing and high fever. The history of the present illness included paroxysmal atrial flutter which was untreated, but she had not developed heart failure.At admission, auscultation of the chest revealed moist rales and systolic murmur but did not clearly show the presence of fixed splitting of S2.

Red blood cell distribution width as an effective tool for detecting fatal heart failure in super-elderly patients.

Objective: Red blood cell distribution width (RDW) is a numerical measure of erythrocyte size variation. It has been recently reported to be an independent prognostic marker of heart failure (HF). Previous studies on RDW were mostly designed for middle-aged and elderly patients (60-79 years old), therefore, there is no established limit for super-elderly patients (≥ 80 years old).

Deletion of the Fc receptors gamma chain preserves endothelial function affected by hypercholesterolaemia in mice fed on a high-fat diet.

Aims: To clarify the role of Fc receptors (FcR) for immunoglobulin in endothelial dysfunction induced by hypercholesterolaemia, we evaluated the effect of deletion of the FcR gamma chain on endothelium-dependent relaxation and oxidative stress after 10 weeks on a high-fat diet in FcR gamma(-/-) mice compared with that in wild-type mice.

Methods And Results: Plasma cholesterol levels of those on the high-fat diet were significantly increased compared with those on the normal chow diet in both groups of mice. Endothelium-dependent relaxation of the aortic ring with acetylcholine in wild-type mice was significantly reduced by the high-fat diet (ED(50): 0.

Serial angiographic follow-up beyond 10 years after coronary artery bypass grafting.

Background: The long-term prognosis and serial angiographic follow-up beyond 10 years in patients who underwent coronary artery bypass grafting (CABG) have not been fully studied in Japan.

Methods And Results: In the present study data from 71 patients who underwent CABG before 1992 were analyzed. Thirty patients had a saphenous vein graft (SVG) only group, and the remaining 41 had a left internal thoracic artery graft to the left anterior descending coronary artery (LITA) group; 6 patients died from malignancy, which was the most common cause of death after CABG.

R/R genotype of human paraoxonase (PON1) is more protective against lipoprotein oxidation and coronary artery disease in Japanese subjects.

Human paraoxonase (PON1) is an high-density lipoprotein (HDL) -associated enzyme that is proposed to protect against the oxidation of lipoproteins. Recently, the association of coronary artery disease (CAD) and PON1 activity was reported. Furthermore, the R/R genotype of PON1 has been related to the risk for CAD.
