Why beta adrenergic drug should not be advised to a patient with ischemic heart disease?

Beta-blockers, without partial agonist activity, should not be stopped abruptly, particularly in patients with, or at high risk of, co-existant ischaemic disease because of the danger of post-beta-blockade cardiac sympathetic hypersensitivity; alternatively bed rest should be instituted to reduce the risk of …

Why are beta-blockers bad for seniors?

It is argued that the use of beta blockers in older adults may not be justified because of physiologic changes in people over 60 years of age. These include a low cardiac output, bradycardia, high total peripheral resistance, reduced renal blood flow and glomerular filtration rate, and low plasma renin activity [18].

Patients with COPD or asthma who were not on beta-agonist had lower one-year mortality if they were on BBs.

Are there any nonselective alpha-adrenergic blocking agents?
