Detaljeret beskrivelse
One hundred and fifty six patients have been enrolled so far. Methods were as described below:
- Muscle sympathetic nerve activity (MSNA) was directly recorded from the peroneal nerve using the microneurography technique ;
- All patients underwent symptom-limited cardiopulmonary exercise test performed on a cycle ergometer, using a ramp protocol with workload increments of 5 or 10 Watts per minute;
- Body composition measurements were performed using dual-energy X-ray absorptiometry (DXA);
- Muscle strength was assessed by handgrip dynamometer using the mean value of three attempts;
- Blood samples were drawn in the morning after 12h overnight fasting. The laboratory tests included B-type natriuretic peptide (BNP; pg/mL) plasma level, serum sodium (mEq/L), serum potassium (mEq/L), creatinine (mg/dL), haemoglobin level (g/dL), high-sensitivity C-reactive protein (CRP; mg/L), lipid profile (triglyceride, total cholesterol, high-density lipoprotein, and low-density lipoprotein; mg/dL), and fasting glucose (mg/dL). Blood sample to assess hormone plasma levels were also drawn at the same time: total testosterone (TT), free testosterone (FT), sex hormone binding globulin (SHBG), dehydroepiandrosterone sulfate (DHEAS), luteinizing hormone (LH), follicle-stimulating hormone (FSH), thyroid stimulating hormone (TSH) and insulin-like growth factor 1 (IGF1).

Low testosterone
Patients with HF and testosterone deficiency.
|
Oxygen consumption (VO2) and carbon dioxide output (VCO2) were measured by means of gas exchange on a breath-by-breath basis.
The patients were initially monitored for 2 minutes at rest when seated on the ergometer, after that they were instructed to pedal at a pace of 60-70 rpm and the completion of the test occurred when, in spite of verbal encouragement, the patient reached maximal volitional fatigue.
Multiunit post-ganglionic muscle sympathetic nerve recordings were made using a tungsten microelectrode placed in the peroneal nerve near the fibular head.
Nerve signals were amplified by a factor of 50,000 to 100,000 and band-pass filtered (700 to 2000 Hz).
For recording and analysis, nerve activity was rectified and integrated (time constant 0.1 seconds) to obtain a mean voltage display of sympathetic nerve activity.
Dual-energy X-ray absorptiometry (DXA) scan was used to measure total lean mass, body fat and bone mineral content.
Venous occlusion plethysmography was used to assess non-invasively blood flow.
Blood samples were drawn in the morning after 12h overnight fasting.
Muscle strength was assessed by handgrip dynamometer using the mean value of three attempts.
