ABSTRACT

Cognitive impairment often occurs in elderly patients with heart failure.In this paper, we reviewed the possible mechanism of cognitive impairment in elderly patients with heart failure.The possible pathological mechanism of cognitive impairment in elderly patients with heart failure was discussed from the aspects of decreased cardiac output, renal damage, atrial fibrillation, inflammatory reaction, neuroregulation, depression and high homocysteine level, and the effect of cognitive impairment on heart failure was also summarized, so as to improve both the clinicians' awareness of cognitive impairment and the level of diagnosis and treatment in elderly patients with heart failure.
