A review of the association between congestive heart failure and cognitive impairment.

Heart failure is a growing epidemic with an estimated 5 million Americans suffering from this condition. Several clinical trials have demonstrated a high correlation between congestive heart failure (CHF) and cognitive impairment. The severity of cognitive impairment correlates positively with the degree of CHF. The underlying mechanism for cognitive impairment remains unclear but appears to be related to cerebral hypoperfusion and impaired cerebral reactivity with selective impairment of verbal memory and attention domains. Furthermore, cognitive dysfunction represents one aspect of frailty, a novel concept that encompasses a range of clinical conditions that results in functional impairment in patients with heart failure. In addition, frailty independently predicts mortality in CHF patients. Cognitive impairment is a common and predictable effect of CHF that contributes with social and behavioral problems to decreased compliance to prescribed therapy and increased hospital readmissions. A multidisciplinary approach is necessary to deal with the complexity of this clinical syndrome

Exercise training corrects control of spontaneous calcium waves in hearts from myocardial infarction heart failure rats

Impaired cardiac control of intracellular diastolic Ca<sup>2+</sup> gives rise to arrhythmias. Whereas exercise training corrects abnormal cyclic Ca<sup>2+</sup> handling in heart failure, the effect on diastolic Ca<sup>2+</sup> remains unstudied. Here, we studied the effect of exercise training on the generation and propagation of spontaneous diastolic Ca<sup>2+</sup> waves in failing cardiomyocytes. Post-myocardial infarction heart failure was induced in Sprague–Dawley rats by coronary artery ligation. Echocardiography confirmed left ventricular infarctions of 40 ± 5%, whereas heart failure was indicated by increased left ventricular end-diastolic pressures, decreased contraction-relaxation rates, and pathological hypertrophy. Spontaneous Ca<sup>2+</sup> waves were imaged by laser linescanning confocal microscopy (488 nm excitation/505–530 nm emission) in 2 μM Fluo-3-loaded cardiomyocytes at 37°C and extracellular Ca<sup>2+</sup> of 1.2 and 5.0 mM. These studies showed that spontaneous Ca<sup>2+</sup> wave frequency was higher at 5.0 mM than 1.2 mM extracellular Ca<sup>2+</sup> in all rats, but failing cardiomyocytes generated 50% (P < 0.01) more waves compared to sham-operated controls at Ca<sup>2+</sup> 1.2 and 5.0 mM. Exercise training reduced the frequency of spontaneous waves at both 1.2 and 5.0 mM Ca2+ (P< 0.05), although complete normalization was not achieved. Exercise training also increased the aborted/completed ratio of waves at 1.2 mM Ca<sup>2+</sup> (P < 0.01), but not 5.0 mM. Finally, we repeated these studies after inhibiting the nitric oxide synthase with L-NAME. No differential effects were found; thus, mediation did not involve the nitric oxide synthase. In conclusion, exercise training improved the cardiomyocyte control of diastolic Ca<sup>2+</sup> by reducing the Ca<sup>2+</sup> wave frequency and by improving the ability to abort spontaneous Ca<sup>2+</sup> waves after their generation, but before cell-wide propagation
