The SUEC model incorporates early supported discharge and community rehabilitation, resulting in decreased length of stay and increased patient satisfaction.
A new study reveals that approximately 40% of stroke patients would benefit from rehabilitation, but only 16% receive it. The rates vary widely by province and hospital, with some patients not needing or getting the right amount of services. This lack of access has huge implications for their quality of life and healthcare utilization.
Researchers found that oleate, a common dietary fat, restored proper metabolism of fuel in an animal model of heart failure. This improvement enabled the heart muscle to access energy more efficiently and reduced toxic fatty byproducts.

These findings suggest that race and ethnicity should be considered when designing obesity prevention programs to effectively reduce heart disease risk.
Heart failure affects millions worldwide, yet awareness is low among politicians, healthcare professionals, and the public. Many cases are preventable and treatable, improving quality of life and survival.
Researchers at the University of Warwick discovered that methylglyoxal damages 'good' HDL cholesterol, reducing its protective function against heart disease. Low levels of HDL are linked to increased risk of heart disease, and MG levels can be managed through diet and supplements.
Death rates from heart disease and stroke are declining overall in Europe, but at differing rates. Cardiovascular disease remains the leading cause of death among Europeans, accounting for close to half of all deaths. However, cancer is now causing more deaths than heart disease in some countries, particularly among men.

A lack of cardiac rehabilitation programs worldwide is a significant issue, particularly in low-income and middle-income countries. York University Professor Sherry Grace emphasizes the importance of integrating these programs into cardiac care to reduce deaths, re-hospitalization rates, and improve quality of life.
A new multi-center study found that consuming even light amounts of alcohol has no cardiovascular benefits and may even increase risk. The research, published in The BMJ, analyzed data from over 260,000 people and found that reducing alcohol consumption, even for moderate drinkers, can lead to improved heart health.
Severe obesity is associated with considerable excess risk for cardiovascular diseases in young Hispanic adults, according to a new study. Young adults with severe obesity are more likely to develop high blood pressure and diabetes, both risk factors for heart disease.
A new study published in the American Journal of Transplantation found that older kidney donors experience similar longevity and cardiovascular health as healthy individuals. The research, led by Dr. Peter Reese, suggests that donation does not significantly increase the risk of death or heart disease among older adults.
Half of US adults suffer from at least one chronic condition, with a quarter having two or more. The report highlights the need for coordinated action to reduce the chronic disease burden, including promoting health and healthy behaviors, effective prevention services, and stronger links between healthcare and community services.

However, some children with complex heart disease can be exposed to large cumulative doses that increase estimated lif...
Researchers at Duke University Medical Center found that children with heart disease have low lifetime cancer risk from X-rays, but those undergoing repeated complex imaging tests face a slightly increased risk. The study of 337 children aged six and younger showed a 0.07% average increase in lifetime cancer risk.
Researchers found that even modest delays in TAVR can significantly impact its effectiveness in severely ill patients. Modest increases in wait times reduced the treatment's benefits, while prolonged waits made it less effective than surgery for high-risk surgical candidates.
A study found that Hispanics have reduced the gap in taking prescribed heart medicines since the 2006 launch of Medicare's prescription drug benefit. Medication adherence increased most among whites and Hispanics, but only slightly among African-Americans.
A systematic review and meta-analysis of over 850,000 people shows that women with diabetes are nearly three times more likely to develop coronary heart disease than women without diabetes. Men with diabetes are twice as likely to develop CHD. The study suggests that sex-specific interventions could improve the prevention of CHD.
A new low-carb vegan diet, called Eco-Atkins, has been shown to reduce the risk of heart disease and aid in weight loss. The diet combines elements of both vegan and low-carbohydrate diets, resulting in a 10% decrease in cholesterol levels over six months.
A seven-year study of nearly 900 middle-aged overweight women found that physical activity reduced the risk of developing heart disease. Low-to-moderate physical activity was the only lifestyle factor that protected these women from becoming at-risk for heart disease.
A University of Florida study reveals that gum disease bacteria increase risk factors for atherosclerotic heart disease in mice, potentially changing how physicians diagnose and treat heart disease patients. The study's findings support a causal link between oral disease and increased heart disease risk.
Two studies indicate that more intense exercise does not always mean better for heart health. Overdosing on high-intensity exercise may actually increase the risk of death from a heart attack or stroke in those with existing heart disease. Moderate exercise at moderate intensity is key to maximizing cardiovascular benefits.
A new study finds that women who experience early menopause at ages 40-45 are 40% more likely to develop heart failure than those who enter menopause between 50-54. Smoking also significantly increases the risk of heart failure in these women.
