Investigating microRNA Biomarkers in Acute Myocardial Infarction

MicroRNAs (miRNAs) are small non-coding RNA molecules which perform a critical regulatory function in gene translation through the degradation or silencing of target mRNAs. They are included in a varied range of biological processes such as proliferation and differentiation, hemostasis, metabolism, inflammation or apoptosis, and also in the pathophysiology of several diseases.

			High muscle volume in middle age tied to lower cardiovascular disease risk Middle-aged adults who have more muscle mass have decreased cardiovascular disease, a new study suggests. Higher levels of lean muscle mass in middle age are tied to a lower 10-year cardiovascular disease (CVD) risk, regardless of conventional risk factors like obesity, diet, income, diabetes, high blood pressure, smoking, and abnormal cholesterol levels.

			Nutritional supplements offer no protection against cardiovascular diseases, say researchers A new study warns that most dietary supplements do nothing to protect against cardiovascular diseases, including heart disease, stroke, and even heart attacks. Based on the research, the team of researchers from West Virginia University concluded that most nutritional supplements do not offer protection against potentially fatal heart conditions.

	Weight gain between 20 and 40 years of age linked to early death People who gain weight in their 20s, 30s, and 40s are at an increased risk of premature death, according to a study of US adults published in The BMJ. Researchers at Huazhong University of Science and Technology found that people who became obese between the ages of 25 and 47 were at a 22% increased risk of premature death from any cause and a 49% increased risk of dying from heart disease.

	Sudden death due to heart disease – it could be in the genes More than 220,000 American adults die suddenly of cardiac causes – a phenomenon called sudden cardiac death. Some sources put it as closer to 400,000. Both inexplicable and distressing, this has been the subject of a new study published in the Journal of the American College of Cardiology and presented at the American Heart Association’s scientific session.

	Women with gestational hypertension have elevated cardiovascular risk later in life Research published online today in Journal of the American College of Cardiology, confirms that women who have gestational hypertension or preeclampsia in at least one pregnancy will have higher cardiovascular risk than women without such a history, and that this elevated risk persists at least into their 60s.

	New study aims to optimize brain development in babies with congenital heart disease An upcoming clinical trial at Children's National Hospital will harness cardiopulmonary bypass as a delivery mechanism for a novel intervention designed to stimulate brain growth and repair in children who undergo cardiac surgery for congenital heart disease.
