The mechanism for slow pulmonary O2 uptake (V̇o2) kinetics in patients with chronic heart failure (CHF) is unclear but may be due to limitations in the intramuscular control of O2 utilization or O2 delivery. Recent evidence of a transient overshoot in microvascular deoxygenation supports the latter. Prior (or warm-up) exercise can increase O2 delivery in healthy individuals. We therefore aimed to determine whether prior exercise could increase muscle oxygenation and speed V̇o2 kinetics during exercise in CHF. Fifteen men with CHF (New York Heart Association I–III) due to left ventricular systolic dysfunction performed two 6-min moderate-intensity exercise transitions ( bouts 1 and 2, separated by 6 min of rest) from rest to 90% of lactate threshold on a cycle ergometer. V̇o2 was measured using a turbine and a mass spectrometer, and muscle tissue oxygenation index (TOI) was determined by near-infrared spectroscopy. Prior exercise increased resting TOI by 5.3 ± 2.4% ( P = 0.001), attenuated the deoxygenation overshoot (−3.9 ± 3.6 vs. −2.0 ± 1.4%, P = 0.011), and speeded the V̇o2 time constant (τV̇o2; 49 ± 19 vs. 41 ± 16 s, P = 0.003). Resting TOI was correlated to τV̇o2 before ( R2 = 0.51, P = 0.014) and after ( R2 = 0.36, P = 0.051) warm-up exercise. However, the mean response time of TOI was speeded between bouts in half of the patients (26 ± 8 vs. 20 ± 8 s) and slowed in the remainder (32 ± 11 vs. 44 ± 16 s), the latter group having worse New York Heart Association scores ( P = 0.042) and slower V̇o2 kinetics ( P = 0.001). These data indicate that prior moderate-intensity exercise improves muscle oxygenation and speeds V̇o2 kinetics in CHF. The most severely limited patients, however, appear to have an intramuscular pathology that limits V̇o2 kinetics during moderate exercise.

Medication knowledge and assistance in older chronic heart failure (CHF) patients. Medication adherence is central to the optimal management of CHF. Little is known about older patients’ knowledge of their medications or the factors that contribute to this knowledge. Aim: To describe and identify the predictors of medication knowledge in older CHF patients. Method: Subjects ( n = 62) aged over 55 years with moderate heart failure (New York Heart Association Class II and III) who identified as self-managing were recruited from hospital or rehabilitation. Interviews occurred at home four weeks post-discharge using a medication checklist and the Self-Efficacy in Chronic Illness Scale (Lorig et al, 2001). Multiple regression analysis determined the predictors of medication knowledge. Results: Patients were aged mean 78.4 years (sd 8.54 years), mostly male (57%) and had an average 8 (median, range 3–22) medications to take daily, of which 6 (median, range 3–14) were for CHF. Most managed their own medications (54%) but more than a quarter (28%) were assisted by reminding, dispensing and supervision. Compliance with medications was high (84%), although only half (53%) knew the name, main purpose and side effect of their medications. Patients with better self-efficacy (β = 2.88) and no help with medication (β = -21.05) had better medication knowledge (model F = 13.6, p = .000, R = .61, r 2 = .37). Conclusion: Older CHF patients have poor knowledge of their medications, which may be improved by promoting overall self-efficacy for disease management. Less knowledgeable patients received appropriate assistance with medications, but the consequence may be less knowledge and thus warrants further investigation.

Aim. Еvaluate the influence of combination therapy with fosinopril or zofenopril on the regulatory-adaptive status (RAS) of patients with diastolic chronic heart failure (CHF). Material and methods. The study includes 80 patients with CHF I-II functional class according to the classification of the New York heart Association with left ventricle ejection fraction ≥50% because of hypertensive disease (HD) of III stage, who were randomized into two groups for treatment with fosinopril (14.7±4.2 mg/day, n=40) or zofenopril (22.5±7.5 mg/day, n=40). As part of combination pharmacotherapy, patients were included nebivolol (7.1±2.0 mg/day and 6.8±1.9 mg/day), in the presence of indications, atorvastatin and acetylsalicylic acid in the intestinal shell were prescribed. Initially and after six months, the following was done: a quantitative evaluation of the RAS (by cardio-respiratory synchronism test), echocardiography, tredmil-test, six-minute walking test, determination of the N-terminal precursor of the natriuretic brain peptide level in blood plasma and subjective evaluation of quality of life. Results. Therapy, using fosinopril, in comparison with zofenopril, more improved RAS (by 66.5%, p

We investigated the plasma levels of tumour necrosis factor-alpha [TNF-alpha], leptin and insulin, and their relation to body mass index [BMI] in 80 male patients who presented with chronic heart failure [mean age: 47 +/- 4 years] at Tanta University Hospital. Plasma leptin, TNF-alpha and insulin were significantly increased and BMI significantly decreased in New York Heart Association classes III and IV patients. TNF-alpha, leptin and insulin were positively correlated, and TNF-alpha and BMI and leptin and BMI were negatively correlated in stages III and IV of heart failure. We conclude that cytokine neuroendocrine activation may form part of advanced stage heart failure. It may also be responsible for worsening cachexia, and can be used as a marker to determine disease severity.

High levels of inflammation play an important role in chronic heart failure (CHF). Patients with CHF have elevated levels of pro-inflammatory cytokines circulating systemically, mainly TNF and IL-6. However, there are almost no studies that relate these levels to the functional status of patients in CHF, much less to their CMV serostatus. In this study, patients with CHF (n=40; age=54.9 ± 6.3; New York Heart Association functional classification (NYHA, I-III) and healthy controls (n=40; age=53.5 ± 7.1) were analyzed. The serum concentrations of nine pro- and anti-inflammatory cytokines were measured by Luminex® xMap Technology and the basal level of mRNA expression of some immune molecules was quantified by TaqMan™ Array in CD4+ T-lymphocytes. The concentration of these cytokines in culture supernatants in response to anti-CD3 and LPS was also measured. The percentage of CD28null T-cells was determined, as well as the antibody titer against CMV. We found a higher concentration of all cytokines studied in CHF serum compared to healthy controls, as well as a direct correlation between functional status in CHF patients and levels of inflammatory cytokines. Moreover, the highest cytokine concentrations were found in patients with higher concentrations of lymphocytes lacking CD28 molecule. The cytokine production was much higher in CMV+ patients, and the production of these cytokines was found mainly in the T-lymphocytes of CMV+ patients in response to anti-CD3. Anti-CMV antibody levels were positively correlated with cytokine levels. The baseline expression of specific mRNA of the main molecules involved in the Th1 response, as well as molecules related to the CD4+CD28 null subset was higher in CMV+ patients. The cytokine concentrations are higher in CHF CMV+ patients and these concentrations are related to the production of antibodies against CMV. These high levels of cytokines are also associated with the more differentiated CD28null lymphocyte populations. All this, together with the dynamics of the pathology itself, makes CMV+ patients present a worse functional status and possibly a worse evolution of the pathology.

• Background The outpatient costs of medications prescribed for chronic heart failure are high and are often borne by individual patients. Lack of financial resources may force noncompliance with use of medications. • Objective To compare the outpatient costs of medications for patients with different New York Heart Association classifications of chronic heart failure. • Methods The charts of 138 patients with chronic heart failure were reviewed retrospectively. Outpatient costs of medications were obtained from the Web sites of commercial pharmacies. Medications were classified by type according to the system of the American Heart Association. A mean cost for each classification of medication was used for analysis. • Results The overall mean monthly cost of medications for chronic heart failure was $438. Patients with class II and class III chronic heart failure had the highest costs: $541 and $514, respectively. Analysis of variance indicated that the differences in monthly costs of medications between the patients with the 4 stages of chronic heart failure were significant (F = 4.86, P = .003). A post hoc Scheffé test revealed significant differences in costs between patients with class I and patients with class II heart failure (P=.02) and between patients with class I and those with class III heart failure (P=.02). • Conclusions The outpatient costs of medications for chronic heart failure are significant. Ability to pay for prescribed medications must be determined. Healthcare professionals must maintain an awareness of the costs of medications and patients’ ability to pay.
