As fewer Americans die from heart attacks, more succumb to chronic heart disease

Image
  From 1970 to 2022, deaths from heart attacks dropped by almost 90%, but more Americans now die from other types of heart disease, Stanford Medicine-led research has found. In 1970, someone over the age of 65 hospitalized for a heart attack in the United States had about a 60% chance of leaving the hospital alive. Today, the survival rate is over 90%, with even better outcomes for younger patients. Those numbers have contributed to a remarkable decrease in the likelihood of dying from any type of heart disease over the last 50 years, according to a new study of heart disease mortality led by Stanford Medicine researchers. In 1970, 41% of all deaths were attributed to ailments of the heart; in 2022, that statistic had dropped to 24% of all deaths.  Most strikingly, the proportion of deaths from acute myocardial infarctions — commonly known as heart attacks — fell nearly 90% during that period. The decrease is a testament to the leaps and bounds made in our ability to manage an...

Impact of Sleep Disorders and Disturbed Sleep on Brain Health: A Scientific Statement From the American Heart Association

Image
  Accumulating evidence supports a link between sleep disorders, disturbed sleep, and adverse brain health, ranging from stroke to subclinical cerebrovascular disease to cognitive outcomes, including the development of Alzheimer disease and Alzheimer disease–related dementias. Sleep disorders such as sleep-disordered breathing (eg, obstructive sleep apnea), and other sleep disturbances, as well, some of which are also considered sleep disorders (eg, insomnia, sleep fragmentation, circadian rhythm disorders, and extreme sleep duration), have been associated with adverse brain health.  Understanding the causal role of sleep disorders and disturbances in the development of adverse brain health is complicated by the common development of sleep disorders among individuals with neurodegenerative disease. In addition to the role of sleep disorders in stroke and cerebrovascular injury, mechanistic hypotheses linking sleep with brain health and biomarker data (blood-based, cerebrospina...

Cycling Boosts Brain Function in Parkinson’s Disease

Image
A novel study conducted at University Hospitals and the VA Northeast Ohio Healthcare System, through its Cleveland Functional Electrical Stimulation (FES) Center, provides clues, as it shows that long-term dynamic exercise programs might have wider restorative effects on the brain signals of Parkinson’s Disease (PD) patients than researchers previously thought. Researchers used recordings from participants’ deep brain stimulation devices to try to assess how long-term exercise programs might be re-activating connections damaged by Parkinson’s Disease. Unlike previous studies, this investigation sought to decode the brain changes linked to motor symptom relief; both with the help of second-generation DBS devices and a long-term dynamic cycling exercise regimen in Parkinson’s patients. Details on the study are published in the June 2025 issue of  Clinical Neurophysiology . The pilot investigation, funded by a VA Merit Award from the Department of Veterans Affairs along with philanthr...
