Research in recent years has linked a person’s physical or social environment to their well-being. Stress wears down the body and compromises the immune system, leaving a person more vulnerable to illnesses and other conditions. Various stressors, from family adversity to air pollution, can lead to inflammation, diabetes and heart disease.
Scientists at the Peter Munk Cardiac Centre, at the University Health Network, have identified the type of cell key to helping the heart repair and potentially regenerate following a heart attack.
CLEVELAND: In concurrent studies, Cleveland Clinic researchers have uncovered new mechanisms that demonstrate why and how regularly eating red meat can increase the risk of heart disease, and the role gut bacteria play in that process. The research, led by Stanley Hazen, M.D., Ph.D., builds upon previous work showing TMAO (trimethylamine N-oxide) – a gut bacteria byproduct formed during digestion – can lead to the development of cardiovascular disease, including heart attacks and strokes
More and more, through sequencing done for medical reasons or done by direct-to-consumer companies, people learn they have variants of disease genes with uncertain significance to their health. With a new assay, researchers have a way to determine the potential impact of these cardiomyopathy variants on the health of patients and their family members.

Os investigadores da Mayo Clinic constataram que um medicamento oral, apixabana, utilizado para tratar a formação de coágulos de sangue em pacientes submetidos a terapia contra o câncer, é seguro e eficaz. O medicamento foi associado a uma menor quantidade de complicações hemorrágicas e menos formação recorrente de coágulos sanguíneos, em comparação com a heparina de baixo peso molecular. Os resultados foram apresentadas na assembleia anual da Sociedade Americana de Hematologia por Robert McBane II M.D., um cardiologista da Mayo Clinic.

Many of the substances that humans consume on a regular basis as parts of their basic diet actually contain harmful toxins. Rice, barbecued meat and drinking water all pose threats to human health as hosts to potent toxins, carcinogens and opportunistic pathogens. In many cases, the rise in concentrations of these harmful substances is a direct result of human activity, such as the use of harmful pesticides in crops and even advances in green technology.
Conrad Tucker, associate professor of engineering design and industrial engineering, demonstrates how a mobile-based application will use a cellphone camera and computer vision techniques to capture pulse rate. Tucker and his team use a Masimo Rad-97, a compact, portable patient monitoring device which measures pulse rate, respiratory rate, oxygen saturation, perfusion index, total hemoglobin and pleth variability index, as a ground to compare the application's captured data.

The finding may pave the way for new drugs to stop or even reverse the progression of serious kidney disease in humans—and other potentially lethal conditions of the heart, liver, and brain as well.
Black patients with atrial fibrillation are significantly less likely to receive oral anticoagulants--particularly newer, more effective versions-- than white and Hispanic patients.
Some patients with coronary artery disease have inadequate blood flow to the heart muscle during periods of mental/emotional stress. This condition – called "mental stress-induced myocardial ischemia" (MSIMI) – is related to the severity of plaque buildup in the coronary arteries in men but not women, reports a study in Psychosomatic Medicine: Journal of Biobehavioral Medicine, the official journal of the American Psychosomatic Society. The journal is published in the Lippincott Portfolio by Wolters Kluwer.
