Acidic urine is associated with poor prognosis in patients with chronic heart failure

Renal dysfunction is reported to be associated with poor outcomes in patients with chronic heart failure (CHF). A recent study showed that acidic urine is related to chronic kidney disease, which is a risk factor for the development of CHF. However, it remains to be determined whether acidic urine is associated with poor outcomes in patients with CHF. We measured urine pH using dipsticks in 537 patients with CHF. Acidic urine was defined as urine pH ≤5.5. Patients were prospectively followed during a median follow-up period of 556 days. There were 145 cardiac events. Prevalence of acidic urine was increased with advancing stage of chronic kidney disease. Patients with acidic urine had a more severe New York Heart Association functional class compared with those with normal urine. In the multivariate Cox proportional hazard analysis, acidic urine was independently associated with poor outcomes in patients with CHF after adjustment of confounding factors. A Kaplan–Meier analysis demonstrated that the rate of cardiac events was higher in patients with acidic urine than in those with normal urine. The presence of acidic urine can reliably identify patients at high risk of future cardiac events in patients with CHF.

Clinical depression is common and significantly associated with reduced survival in patients with non-ischaemic heart failure

Several studies have shown that depression is an important predictor of morbidity and mortality in patients with ischaemic heart failure. We have investigated whether clinically recognised depression is linked to mortality in patients with non-ischaemic heart failure due to dilated cardiomyopathy (DCM) in the Royal Brompton Hospital (RBH), a tertiary cardiac centre located in London, UK. We retrospectively examined a cohort of 396 consecutive adult patients with DCM who satisfied our inclusion and exclusion criteria identified from an echocardiographic database and the hospital medical records. Mean age was 53+/-15 years. In all, 83 patients (21%) were clinically depressed, the majority of which (60%) were taking antidepressant therapy. After a follow-up period of 48 months, 83 (21%) patients died, 15 (4%) underwent cardiac transplantation and 130 (33%) were readmitted; 29 (35%) of the deaths and 40 (31%) of the readmissions were among clinically depressed patients. After 5 years, clinically depressed patients had significantly higher mortality and readmission rates than non-depressed; 36 vs. 16% (hazards ratio for death, 3.0; 95% CI, 1.4-6.4; P=0.004), and 87 vs. 74% (hazards ratio for readmission, 0.25; 95% CI, 0.07-0.90; P=0.03), respectively. The risk of depression was greatly increased in the presence of other recognised adverse clinical variables at baseline. Depression increases the risk of death and readmission in patients with heart failure secondary to non-ischaemic DCM. The risk associated with depression appears to be greatest among patients with milder disease, those with a shorter duration of symptoms and those demonstrating a lower systolic or diastolic blood pressure, renal impairment, or a restrictive left ventricular physiology on echocardiography. Interventions targeted at reducing depression warrant further study as a possible way to improve quality of life and/or outcome in patients with heart failure.     

Apoptosis in skeletal myocytes of patients with chronic heart failure is associated with exercise intolerance

OBJECTIVES: The purpose of the study was to investigate if apoptosis occurs in skeletal muscle myocytes and its relation to exercise intolerance in patients with chronic heart failure (CHF). BACKGROUND: Intrinsic abnormalities of skeletal muscle frequently limit exercise tolerance in CHF patients. Recently, apoptosis has been detected in cardiac myocytes of patients with CHF, suggesting that apoptosis may contribute to the reduced contractile force. The presence and regulation of apoptosis in skeletal myocytes of patients with CHF remains to be defined. METHODS: Skeletal muscle biopsies (m. vastus lateralis) of 34 CHF patients (New York Heart Association functional class II-III) and eight age-matched healthy control subjects were analyzed by terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick end-labeling for the presence of apoptosis, and by immunohistochemistry and videodensitometrical quantification for inducible nitric oxide synthase (iNOS) and Bcl-2 expression. Maximal oxygen consumption (VO2max) was determined by ergospirometry. RESULTS: Apoptosis was detected in 16/34 (47%) patients with CHF and in none of the healthy subjects. Patients with apoptosis-positive skeletal muscle myocytes exhibited a significantly lower VO2max (12.0 +/- 3.7 vs. 18.2 +/- 4.4 ml/kg/min; p = 0.0005), a higher iNOS expression (6.8 +/- 3.6 vs. 3.7 +/- 2.6% iNOS-positive stained tissue area; p = 0.015) and a lower Bcl-2 expression (1.0 +/- 0.3 vs. 1.4 +/- 0.4% Bcl-2-positive tissue area; p = 0.03) as compared with patients with apoptosis-negative biopsies. CONCLUSIONS: These results indicate that apoptosis is frequently found in skeletal muscle obtained from CHF patients, which is associated with significant impairment of functional work capacity. In skeletal muscle of these patients, iNOS and Bcl-2 are possibly involved in the regulation of apoptosis.
