چکیده
OBJECTIVE To evaluate insulin resistance and systemic inflammation in older patients with systolic (SHF) or diastolic heart failure (DHF). PATIENTS 52 non-diabetic patients (> 70 and < 90 years old) with chronic heart failure (CHF) and hospitalised within the previous six months for heart failure were studied, together with a control group of older healthy volunteers (n = 26). On the basis of Doppler echocardiographic criteria patients were classed as having SHF (n = 27) or DHF (n = 25). MAIN OUTCOME MEASURES Fasting glucose, insulin, C reactive protein, interleukin 6, and tumour necrosis factor alpha soluble receptor II (TNF-alphaSRII) concentrations were determined. Insulin resistance was estimated by the homeostasis model assessment (HOMA). RESULTS HOMA index (median, interquartile range) was higher in patients with DHF (1.77, 1.06-2.26) than in patients with SHF (0.97, 0.81-1.85) or healthy volunteers (1.04, 0.76-1.44; p = 0.01). After adjustment for body mass index, age, and use of angiotensin converting enzyme inhibitors, both groups of patients with CHF were more insulin resistant than were healthy volunteers (p = 0.02). C reactive protein, interleukin 6, and TNF-alphaSRII were all significantly (p < 0.001) higher in patients with DHF and SHF than in healthy volunteers. All markers of systemic inflammation were independently associated with the presence of clinical CHF. CONCLUSION Insulin resistance and inflammatory activation are present in older patients with SHF and DHF.

متن کاملChanges in the structure of the heart and blood pressure after a period of concurrent endurance-resistance training in patients with chronic heart failure
Background: Exercise improves functional capacity by improving endothelial function and musculoskeletal aerobic metabolism, but its effects on hemodynamic control are not well known. The aim of this study was to investigate the effect of aerobic and resistance trainings on structural changes and blood pressure in patients with heart failure. Materials and methods: 76 patients aged 65 to 79 year...

Abstract Background: Diastolic heart failure comprises 50 percent of cases of heart failure. The implications of increased levels of cardiac troponin I (CTnI) on congestive heart failure with preserved systolic function (AHF PEF) have been poorly evaluated. We hypothesized that its level might be elevated in AHF PEF so this evaluation was done in patients referred to Taleghani hospital with ...
