Background Left ventricle diastolic dysfunction is attracting increasing attention of one of the etiologies of chronic heart failure (CHF). Methods and ResultsThe study sample included 560 patients with CHF who were hospitalized during the 5-year period. They were classified into 2 groups according to the left ventricular ejection fraction (LVEF): reduced group (LVEF <50%, n=431); or preserved group (LVEF ≥50%, n=129). The degree of cardiac symptoms did not differ between the 2 groups; however, no difference was found between the 2 groups in the mortality rate (P=0.898), and readmission rates (P=0.674). The results of a multivariate analysis using a Cox proportional hazards model to identify predictors of the prognosis of heart failure revealed no difference in prognosis according to the presence/absence of decreased LVEF, whereas renal dysfunction and anemia were identified as significant prognostic determinants. Also, in the reduced group, the administration of angiotensin-converting enzyme inhibitors (ACE-I) and/or angiotensin II receptor blockers (ARB), β-blockers reduced mortality. In the preserved group, ACE-I and/or ARB administration reduced mortality, whereas β-blockers did not. Conclusion In the present study, the likelihood of LVEF influencing prognosis was considered to be low, with the contribution of non-cardiac factors such as renal function and anemia concluded to be greater.

The lipid-lowering and anti-atherosclerotic effects of atorvastatin (10 mg/day) were investigated by measuring changes in the levels of oxidized low-density lipoprotein (LDL), serum lipids (total cholesterol [TC], LDL-cholesterol [LDL-C] and triglycerides [TG]), and in the protein adiponectin. This was undertaken in 22 patients with ischaemic heart disease and serum LDL-C levels > 100 mg/dl. After 3 months of therapy, atorvastatin significantly decreased serum lipids, oxidized LDL was reduced from 457.0 ± 148.6 to 286.9 ± 88.5 nmol/l, and adiponectin increased from 9.7 ± 7.4 to 13.9 ± 9.98 mg/ml. No significant correlation was observed between adiponectin and LDL-C, TG and high-density lipoprotein cholesterol. Atorvastatin therapy was not associated with side-effects, such as myalgia and gastrointestinal disorders, and did not give abnormal laboratory test results. It is concluded that atorvastatin decreases serum lipid and oxidized LDL levels, and increases adiponectin levels in patients with ischaemic heart disease.

Abstract. In normal New Zealand white rabbits, immunization with rabbit lung ACE (angiotensin converting enzyme) induced atherosclerotic retinal changes, and glomerular changes similar to those seen in diabetic nephropathy. Also, in genetically diabetogenic rats, immunization with the rabbit lung ACE induced diabetic nephropathy and retinopathy.
