It is difficult to define a threshold value for HR because it must be individualized in the context of the patient's overall hemodynamic status and any pre-existing comorbidities.7 Numerous large, epidemiological studies have shown that elevated HR is an independent risk factor for mortality and morbidity in even healthy individuals with or without hypertension and in patients with CAD, myocardial infarction (MI), or congestive heart failure (CHF).8 Several large placebo-controlled trials have demonstrated that drugs which reduce HR, including
beta blockers, can reduce mortality and morbidity in patients with acute MI or CHF.9
Beta blockers bind to these beta receptors, thereby partially blocking the effects of adrenaline, resulting in a slower heart rate and less forceful contraction of the heart
"The study looks at pathology, which is important, but we also need information on how treatment with
beta blockers affects function and everyday activities."
As the name implies,
beta blockers can specifically block beta receptors without interfering with lung function.
The tablets cost pounds 22 for a full-strength monthly course, while

Beta blockers are equally effective for the treatment of congestive heart failure in women and men, according to a new metaanalysis.
It's worth asking whether gender differences exist in the efficacy of
beta blockers for congestive heart failure (CHF), in light of many previously reported gender differences in the natural history, presentation, diagnosis, and treatment outcomes of coronary artery disease.
[USA], Jan 9 (ANI): According to a research, melanoma patients may live longer if they take
beta blockers, a class of drugs used to manage abnormal heart rhythm and prevent heart attacks.
"If you're on a
beta blocker for high blood pressure, talk with your doctor about it and see if you should make a change," Dr.
However, men who had received
beta blockers as their only blood pressure medication had fewer abnormalities in their brains compared to those who had not been treated for their hypertension, or who had received other blood pressure medications.
Side effects tend to be more common in older adults and can be serious--there is evidence
beta blockers may raise the risk of stroke among elderly users by 19 percent.
In cases of uncomplicated hypertension, other medications, such as diuretics, are preferable to
beta blockers at protecting against stroke and heart attack, according to an analysis reported in the August 14 Journal of the American College of Cardiology (JACC).
