Heart disease is the narrowing or blockage of the arteries and vessels that provide oxygen and nutrient-rich blood to the heart. It is caused by atherosclerosis, an accumulation of fatty materials on the inner linings of arteries that restricts blood flow. When the blood flow to the heart is completely cut off, the result is a heart attack because the heart is starved of oxygen.
Study: Stroke becoming more common in young people – Stroke may be affecting people at a younger age, revealed by researchers. “The reasons for this trend could be a rise in risk factors such as diabetes, obesity and high cholesterol,” said study author Brett Kissela, MD, MS, with the University of Cincinnati College of Medicine in Ohio and a Fellow of the American Academy of Neurology.
Pacemaker could help more heart failure patients – A new study from Karolinska Institutet demonstrates that a change in the ECG wave called the QRS prolongation is associated with a higher rate of heart-failure mortality. According to the team that carried out the study suggests that more heart failure cases could be helped by pacemakers.
Popular antidepressant might prevent heart failure – A medication usually used to help treat depression and anxiety disorders has the potential to help prevent heart failure. John Tesmer, research professor at the U-M Life Sciences Institute and professor in the Department of Pharmacology at the U-M Medical School, and his research team at the Tesmer lab found that paroxetine, a selective serotonin reuptake inhibitor (SSRI) sold under the name Paxil, inhibits G protein-coupled receptor kinase 2 (GRK2), a protein kinase that becomes over-expressed when people have heart failure.
Low birth weight may increase risk for cardiovascular disease, kidney disease and diabetes — New research in The FASEB Journal suggests that poor high blood pressure management during pregnancy may have negative long-term health consequences for offspring – Being underweight at birth may have consequences above and beyond the known short-term effects says a research report. The report shows that rats with a low birth weight have an increased long-term risk for developing cardiovascular disease, kidney disease, and diabetes.
Poor sleep in adolescents may increase risk of heart disease – Adolescents who sleep poorly may be at risk of cardiovascular disease in later life. “We found an association between sleep disturbance and cardiovascular risk in adolescents, as determined by high cholesterol levels, increased BMI [body mass index] and hypertension,” writes lead author Dr. Indra Narang, respirologist and director of sleep medicine at The Hospital for Sick Children (SickKids), Toronto, Ontario.
Moderate alcohol consumption may increase risk of atrial fibrillation in people with heart disease – Moderate alcohol consumption increases the risk of atrial fibrillation in older people with heart disease or advanced diabetes, found a study in CMAJ. “Moderate to high alcohol intake was associated with an increased incidence of atrial fibrillation among people aged 55 or older with cardiovascular disease or diabetes,” writes Dr. Koon Teo, McMaster University, Hamilton, Ontario, with coauthors.
Chronic stress linked to high risk of stroke — ‘Type A’ personality and life stressors boost risk independently of lifestyle factors – Chronic stress, prompted by major life stressors and type A personality traits, is linked to a high risk of stroke. Chronic stress, manifested as physical and/or mental symptoms in response to stressors lasting longer than 6 months has been linked to a heightened risk of heart disease. But its impact on the risk of stroke has not been clear.
Lack of sleep found to be a new risk factor for aggressive breast cancers — First-of-its-kind study published in Breast Cancer Research and Treatment – Lack of sleep is linked to more aggressive breast cancers, according to new findings published in the August issue of Breast Cancer Research and Treatment by physician-scientists from University Hospitals Case Medical Center’s Seidman Cancer Center and Case Comprehensive Cancer Center at Case Western Reserve University.
Exercise boosts mental and physical health of heart failure patients — Exercise results in modest reduction in depressive symptoms for patients with chronic heart failure – Moderate exercise helps ease depression in patients with chronic heart failure, and is also associated with a small but significant reduction in deaths and hospitalizations.
Binge drinking increases the risk of cognitive decline in older adults – Researchers from the Peninsula College of Medicine and Dentistry (PCMD), University of Exeter, suggesting a link between binge drinking in older adults and the risk of developing dementia. The work is supported by the National Institute for Health Research Collaboration for Leadership in Applied Health Research and Care in the South West Peninsula (NIHR PenCLAHRC).
