Atenolol is a beta blocker medication primarily used to treat high blood pressure and heart-associated chest pain. [7] Although used to treat high blood pressure, it does not seem to improve mortality in those with the condition. [8] [9] Other uses include the prevention of migraines and treatment of certain irregular heart beats.
Beta blockers are known primarily for their reductive effect on heart rate, although this is not the only mechanism of action of importance in congestive heart failure. [17] Beta blockers, in addition to their sympatholytic β 1 activity in the heart, influence the renin–angiotensin system at the kidneys.
Increased heart rate and heart muscle contraction are associated with the β1 receptors; however, β 2 cause vasodilation in the myocardium. [citation needed] β3 receptors are mainly located in adipose tissue. [5] Activation of the β 3 receptors induces the metabolism of lipids. [6]
When it comes to resting heart rate, lower is better, says Dr. Steinbaum. “It usually means your heart muscle is in better condition and doesn’t have to work as hard to maintain a steady beat ...
Evidence suggests that reduction of the blood pressure by 5 mmHg can decrease the risk of stroke by 34% and of ischaemic heart disease by 21%, and can reduce the likelihood of dementia, heart failure, and mortality from cardiovascular disease. [2] There are many classes of antihypertensives, which lower blood pressure by different means.
Bradycardia (slow heart rate) Hypotension (low blood pressure) Beta blockers can also interfere with certain other medications, including medication for heart disease and other conditions.
The combination of beta blockers and antihypertensive drugs will work on different mechanism to lower blood pressure. [17] For example, the co-administration of beta-1 blocker atenolol and ACE inhibitor lisinopril could produce a 50% larger reduction in blood pressure than using either drug alone. [18]
Since they promote a lower heart rate and reduce tremor, beta blockers have been used by some Olympic marksmen to enhance performance, though beta blockers are banned by the International Olympic Committee (IOC). [3]
