Patients with both major and minor depression were found to function less well than nondepressed patients, reporting more heart disease symptoms.
A University of Pittsburgh team used electron beam computed tomography and carotid ultrasounds to assess heart disease in living people. They found that pre-menopausal risk factors such as smoking and low-density cholesterol strongly predict the development of coronary artery disease after menopause.
Researchers at the University of Pittsburgh found that HbA1 levels predict mortality from coronary artery disease in women with Type 1 diabetes. However, this association was not seen in men with the same condition. The study analyzed data from over 600 subjects and suggests a gender-specific link between hyperglycemia and CAD risk.
A new UCSF study reveals that women are as likely as men to agree to a doctor's recommendation for an invasive cardiac procedure after testing positive for heart disease. The study also found that men and women reported similar willingness to accept recommendations for coronary angioplasty or coronary artery bypass graft surgery.
Researchers suggest a clear connection between periodontal disease and cardiovascular disease, with bacteria and toxins traveling through the bloodstream. Periodontal bacteria contain lipopolysaccharides that can cause illness and damage blood vessel linings.
A lifetime of poor health can start with conditions in the womb, according to Cornell University researcher Peter W. Nathanielsz. He argues that adults may suffer diseases due to incompletely formed organs during vulnerable periods of development. The book emphasizes the importance of prenatal care and nutrition for future generations.
Researchers found that heart patients with high levels of social support show fewer symptoms of depression, while those with low social support tend to have higher levels of depression. Interventions that decrease hostility and increase social support may also benefit heart disease patients.
