A study by Johns Hopkins researchers found that nearly one in four heart attack patients suffer from depression, which makes them less likely to modify their diets and exercise more often. The study also showed that depressed patients had greater difficulty following recommended lifestyle and behavior change recommendations.
A team of chemists has created a completely synthetic vaccine by synthesizing the epitope of Neisseria meningiditis. The new vaccine uses a system that mimics conventional vaccines and may offer fewer side effects. Researchers are optimistic about the potential for this technology to improve vaccine development in the future.
Researchers found high levels of proinflammatory cytokine TNF in individuals with congestive heart failure (CHF), which can damage the heart. Inhibiting TNF through treatment improved patients' signs and symptoms of cardiac failure, including exercise tolerance and heart pumping ability.
A University of Georgia study found that blood vessels from African Americans generate more free radicals than those from Caucasians, which may contribute to the higher incidence of cardiovascular disease in African Americans. The increased free radical production could be linked to reduced vasodilation and increased blood pressure.
Studies of over 25,000 Emory angioplasty and coronary bypass patients reveal significant improvements in patient outcomes, including shorter hospital stays and decreased mortality rates. Hospital costs also decreased by 30% between 1988 and 1996, with a notable reduction in the last two years.
Researchers found that frequent vigorous exercise reduces heart attack risk, with the greatest benefit seen in men who exercised five or more times a week. The study of over 22,000 physicians suggests that shorter exercise periods may also be beneficial for heart health.
The study reveals a family of selenium-based compounds that can lower blood pressure without toxic side effects. These compounds could lead to the development of new therapeutic agents, expanding knowledge on selenium's role in human health.
A study found that women, minorities, elderly, and those with severe heart attacks are less likely to receive clot-busting drugs and other medical procedures. Strong regional variations were also observed in the use of these therapies.
Researchers developed a method to detect early abnormal endothelial cells that lead to atherosclerosis using microbubbles and contrast echocardiography. The technique showed a 40-fold increase in adherence of specific microbubbles to activated endothelial cells, enabling earlier intervention.
Researchers found that men with the highest amounts of iron stored in their bodies had almost three-times the number of heart attacks than men with less iron. The American Heart Association states additional research is needed to prove iron's role in heart disease before screening can be recommended.
A study found that individuals with high cholesterol in middle adulthood continue to have a high risk of heart disease despite declining cholesterol levels over time. Men who experienced the largest decreases in cholesterol still had high initial levels, suggesting that early detection and management are crucial.
Research suggests that a stable fish diet can significantly lower lipoprotein (a) levels, a blood fat linked to increased heart attack risk. The study found a 40% median Lp(a) difference between groups, with fish-eaters having lower levels of the 'bad' cholesterol.
A new study surveyed 26 men and 26 women with congestive heart failure, using standardized measurements to assess their quality of life. Women scored higher than men in physical functioning, bodily pain, general health, vitality, social functioning, mental health scores, depression, and feelings of peacefulness.
A new multicenter randomized clinical trial aims to reduce stroke rates in African Americans by comparing the effectiveness of aspirin and ticlopidine. The study is supported by the National Institute of Neurological Disease and Stroke and will provide free medication to participants.
A new Penn State research project assesses the effectiveness of Telehealth technology in supplementing traditional home health visits for people with diabetes. The project aims to improve patient outcomes and reduce healthcare costs, while expanding access to care for underserved populations.
Researchers at Johns Hopkins Medicine found adenovirus in 71.4% of autopsied hearts from patients with viral myocarditis, a condition previously attributed to Coxsackie B enterovirus. The study suggests adenovirus and enteroviruses may work together to cause this condition.
