Scientists Demonstrate Heart Cell Replication in Mice

...icated by increased ejection fraction and improved ventricular remodeling on echocardiograms, and decreased left-ventricular wall stress on catheterization. The periostin-treated rats also had less scarring of heart tissue, a reduction in infarct size, and a denser network of blood vessels feeding the area. In...

Heart-Assist Device Gives Culver City Man a Good Quality of Life

...ghout my body. I was very close to death. A left ventricular assist device (LVAD), the HeartMate XVE assumes the work of the hearts left ventricle, the main pumping chamber of the heart. The mechanical device can pump up to 10 liters of blood per minute, which is more than adequate for most patients, according...

Low Serum Potassium Levels Linked to Increased Death Risk in Heart Patients

...assium associated deaths were sudden deaths due to ventricular arrhythmias, he added. The findings of the study were published in the June issue of the European Heart Journal....

Understanding and Treating Congenital Diaphragmatic Hernia

...authors state. In addition, they suggest that left ventricular hypoplasia, commonly seen in prenatally diagnosed cases with CDH (in which the enlarged right ventricle compresses the left ventricle) is often reversible, unlike true hypoplasia in which the heart is underdeveloped. Accordingly, the diagnosis of hyp...

Aerobics Turn Enlarged Heart into a Trimmer, More Efficient Organ

...we didn't know the effects of exercise training on ventricular remodelling," Dr. Haykowsky said. The analysis showed that ejection fraction improved significantly in patients who did aerobic training (2.59 percent, on average). Similarly, the patients' enlarged hearts became significantly smaller, with a reduc...

Most Heart Patients Do Not Need Antibiotics Before Dental Procedures

The new recommendations apply to many dental procedures, including teeth cleaning and extractions. The guidelines emphasize that maintaining optimal oral health and practicing...

Pump Design Could Give Heart Patients New Hope

...nts who received a permanent left heart pump (left ventricular assist device) reduced their risk of dying within one year by 47 per cent," Professor Tan said. "Unfortunately 25 per cent of these patients went on to develop right heart failure syndrome, infection and multi-organ failure. We have developed the de...

Transcendental Meditation Can Help

Further validation of the outcomes of this study is planned via a large, multi-center trial with long-term follow-up. According to the study authors...

Strategy to Reduce Blood Pressure in Low-income African American Men

Both strategies did not help resolve the associated risks of high blood pressure - diabetes and obesity. "The findings are encouraging in that we saw improvements in blood pressure in both groups,"...

Both syndromes can declare their presence silently and catastrophically with a sudden death episode as the first symptom. Because they leave no structural or physical clues, the defects can’t be detected with conventional autopsy ...
