Heart Failure Patients with Better Fitness Likely to have Less Cognitive Impairment

"The message for the patients with heart failure is to do exercises," said study author Ercole Vellone, Professor at University of Rome Tor Vergata, Italy

Heart patients who exercise regularly and have better fitness are likely to have less cognitive impairment, says a study. Fitter patients have better memory, it adds. “The message for the patients with heart failure is to do exercises,” said study author Ercole Vellone, Professor at University of Rome Tor Vergata, Italy.

The study analysed data from over 600 male patients, aged 67-71 years, with heart failure from six countries. During the research, the “Montreal Cognitive Assessment” test was used to measure cognitive function and exercise capacity was measured with a six-minute walk test. The results showed the younger and better educated heart failure patients with better fitness were significantly less likely to have cognitive impairment.

Two-thirds of the patients with heart failure had cognitive problems, showed the study, presented at the EuroHeartCare 2019, a scientific congress of the European Society of Cardiology (ESC), held in Milan, Italy, from May 2 to May 4.

According to the study, cognitive dysfunction is a common problem in the patients with heart failure with 67 per cent reporting at least mild impairment. “There is a misconception that patients with heart failure should not exercise. That is clearly not the case,” Vellone said.

“Find an activity you enjoy and which you can do regularly. It could be walking, swimming or any other activities. There is good evidence that it will improve your health and memory, and make you feel better,” Vellone said. (IANS)

Senior citizens, please take note. Lower sleep quality and variability in night sleep time may adversely affect your ability to recall past events, says a study.

The study, published in Frontiers in Human Neuroscience journal, underscores the importance of sleep in maintaining good cognitive functioning.

The study divided participants in two categories: younger adults (18-37 years) and older adults (56-76 years). The participants were given wearable accelerometers to measure sleep duration and quality over seven nights.

“The night-to-night variability in older adults had a major impact on their performance in tests aimed at evaluating episodic memory,” said Audrey Duarte, Associate Professor at the Georgia Institute of Technology, the US.

Stating that the association between sleep and memory has been known, Duarte said this study underlined the connection particularly among older adults and black participants.

“We wanted to know how sleep affected memory, how well they remembered things and how well their brains functioned depending on how well they slept,” said Emily Hokett, a Ph.D student at the institute.
