Temple researchers identify novel mechanism underlying efficacy of common heart failure drug
(Temple University Health System) Beta-blocker drugs serve a key role in the treatment of heart failure, preventing bombardment of the heart by catecholamines -- substances like epinephrine and norepinephrine -- which overexcite and stress the heart. But not all HF patients respond to beta-blockers, for reasons that are unclear. Now, researchers at the Lewis Katz School of Medicine at Temple University show that dysfunction of beta-adrenergic receptor 3 (β3AR) and consequent decreases in a critical cardioprotective phospholipid may be to blame.

Popular class of drugs reverse potentially harmful genetic changes from heart disease
(York University) Beta blockers are commonly used world-wide to treat a variety of cardiovascular conditions, such as arrhythmias and heart failure. Scientists have known for decades that the medications work by slowing the heart rate and reducing the force of contraction -- lessening the burden of work carried out by the heart. However, new research out of York University has now shown that these drugs also reverse a number of potentially detrimental genetic changes associated with heart disease.

Optimal Beta-blockers May Avert Post-ICD Shock HF Decompensation Optimal Beta-blockers May Avert Post-ICD Shock HF Decompensation
A spike in sympathetic activation after shocks, whether appropriate or not, may raise the risk of heart-failure decompensation within a few months, but maybe less so if beta-blockers are on board.Medscape Medical News (Source: Medscape Medical News Headlines)

Beta-blockers 'useless' for many heart attack patients, study reports
Conclusion This study aimed to see whether beta blockers reduce mortality in people who've had a heart attack but who don't have heart failure or systolic dysfunction. It found no difference between those who were and those who were not given beta-blockers on discharge from hospital. The authors say this adds to the evidence that routine prescription of beta blockers might not be needed for patients without heart failure following a heart attack. Current UK guidelines recommend all people who have had a heart attack take beta blockers for at least one year to reduce risk of recurrent events. Only people with heart failure ...
