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.
Figure 1: The chemical structure of dichloroisoprenaline or dichloroisoproterenol (), abbreviated DCI — the first β-blocker to be developed. β adrenergic receptor antagonists (also called beta-blockers or β-blockers) were initially developed in the 1960s, for the treatment of angina pectoris but are now also used for hypertension, congestive heart failure and certain arrhythmias.

heart failure. The cardio-selective beta-1 blockers could cause adverse effects including bradycardia, reduced exercise ability, hypotension, atrioventricular nodal blockage and heart failure. [5] Other possible adverse effects include nausea and vomiting, abdominal discomfort, dizziness, weakness, headache, fatigue, and dryness in mouth and ...
Heart failure with recovered ejection fraction (HFrecovEF or HFrecEF): patients previously with HFrEF with complete normalization of left ventricular ejection (≥50%). [64] [65] Heart failure may also be classified as acute or chronic. Chronic heart failure is a long-term condition, usually kept stable by the treatment of symptoms.
It is also used to prevent further heart problems after myocardial infarction and to prevent headaches in those with migraines. [4] It is a beta blocker, specifically a selective β 1 receptor blocker, and is taken by mouth or is given intravenously. [4] Common side effects include trouble sleeping, feeling tired, feeling faint, and abdominal ...
Beta blockers: To block the effects of certain hormones on the heart to slow the heart rate. Calcium Channel Blockers: Help slow the heart rate by blocking the number of electrical impulses that pass through the AV node into the lower heart chambers (ventricles). Digoxin: Helps slow the heart rate by blocking the number of electrical impulses ...
Bisoprolol, sold under the brand name Zebeta among others, is a beta blocker which is selective for the beta-1 receptor [7] and used for cardiovascular diseases, [7] including tachyarrhythmias, high blood pressure, angina, and heart failure.
Antihypertensive therapy seeks to prevent the complications of high blood pressure, such as stroke, heart failure, kidney failure and myocardial infarction. Evidence suggests that a reduction of blood pressure by 5 mmHg can decrease the risk of stroke by 34% and of ischaemic heart disease by 21%.
