Cardiovascular Research: Cardiac experts find novel approach to treat heart failure ♦ Blood pressure medication can't undo all damage ♦ Cardiac muscle cells as good as progenitors for heart repair

Blood pressure medication can't undo all damage Patients on antihypertensive medications are still at greater risk of cardiovascular disease, despite controlled numbers. A new study sought to determine whether effective treatment of hypertension could lower the risk of cardiovascular disease to that seen in people who have always had ideal blood pressure levels.
Two lefts make it right: Cardiac experts find novel approach to treat heart failure A teenage girl faced with sudden rapid heart deterioration, a man in the prime years of his life suffering from debilitating heart failure and a former NFL athlete crippled by end-stage heart failure were all successfully treated with a surgical approach recently pioneered in California.
Effect of duration of storage of red blood cells transfused for cardiac surgery Although some studies have suggested that transfusion of stored red blood cell (RBC) concentrates may be harmful, as blood undergoes several physiological changes during storage, an analysis of patients who underwent cardiac surgery in Sweden over a 16-year period found no association between duration of RBC storage and risk of death or serious complications.
Cardiac muscle cells as good as progenitors for heart repair Stem cell therapies for post-heart attack tissue repair have had modest success at best. Clinical trials have primarily used bone marrow cells, which can promote the growth of new blood vessels, but many studies have shown no benefit. A better alternative may be to use human heart muscle cells
