Wednesday, August 15, 2018 -- While pigs still cannot fly, researchers have discovered that the hearts of newborn piglets do have one remarkable ability. They can almost completely heal themselves after experimental heart attacks.
Tuesday, August 14, 2018 -- All physical activities (sports, cycling, and gardening) except walking were associated with a significant decreased risk for myocardial infarction.
Monday, August 13, 2018 -- AbstractBackground Macrophages are highly plastic cells that play an important role in the pathogenesis of cardiovascular disease. Objectives This study investigated the role of GATA3-positive macrophages in modulating cardiac function after myocardial infarction (MI) or in response to pressure overload hypertrophy. Methods Myeloid-specific GATA3-deficient (mGATA3KO) mice were generated, MI or pressure overload was induced, and cardiac function was determined by echocardiography. GATA3-sufficient Cre mice were used as a control. Immunohistochemical staining, flow cytometry, MILLIPLEX Mouse Cytokine/Chemokine Assay, cultured macrophages, quantitative real-time polymerase chain reaction, and western blot were used to determine the role of GATA3 in macrophages. Results GATA3-positive macrophages rapidly accumulated in the infarcted region of the myocardium after acute MI. Deficiency of GATA3-positive macrophages led to a

Monday, August 06, 2018 -- In business, time may be money, but in medical emergencies, healthcare time is life and speed is king—especially when dealing with potential cardiac events. Developing improved diagnostics that can quickly discern whether a patient has had a myocardial infarction or heart attack, is imperative for physicians to move forward with the appropriate treatment course for patients that present with heart attack symptoms. Now, investigators at the University of Texas (UT) Southwestern Medical Center have published new data assessing a novel test that can rule out heart attacks three times faster than conventional methods. Findings from the new study were published recently in Circulation through an article titled “ Evaluation of a Novel Rule-Out Myocardial Infarction Protocol Incorporating High-Sensitivity Troponin T
