Cardiovascular Research: What powers the pumping heart? ♦ More aggressive blood pressure treatment found to reduce heart disease ♦ Aggressive blood pressure treatment found to reduce heart disease,

More aggressive blood pressure treatment found to reduce heart disease, save lives A landmark clinical trial is underway, and has found that a more intensive management of high blood pressure reduces heart disease rates and saves lives.
Low dose beta-blockers as effective as high dose after a heart attack In a surprising finding, heart attack patients treated with a substantially lower dosage of beta-blockers than used in earlier clinical trials showing their effectiveness survived at the same rate, or even better, than patients on the higher doses. Patients receiving one-fourth of the original clinical trial dose had up to a 25 percent decrease in mortality. About 90 percent of patients who have had a heart attack receive beta-blockers, prescribed to prevent future heart attacks.
Early testing can predict stroke patients who will develop upper limb spasticity Many stroke patients suffer from spasticity of the arm that cause pain and impaired sensorimotor function. But there are ways of identifying such patients ahead of time so that they can obtain the earliest possible treatment.

What powers the pumping heart? A treasure trove of proteins has been discovered, which researchers say hold answers about how our heart pumps -- a phenomenon known as contractility. These molecules have not been studied in the heart and little is known about what they do in other tissues.
