Difference between Beta blocker and Vasodilation

Beta blocker vs. Vasodilation

Beta blockers, also written β-blockers, are a class of medications that are particularly used to manage abnormal heart rhythms, and to protect the heart from a second heart attack (myocardial infarction) after a first heart attack (secondary prevention). Vasodilation is the widening of blood vessels.

Adrenaline

Adrenaline, also known as adrenalin or epinephrine, is a hormone, neurotransmitter, and medication.

Alpha blocker

Alpha-blockers, also known as α-blockers or α-adrenoreceptor antagonists, are a class of pharmacological agents that act as antagonists on α-adrenergic receptors (α-adrenoceptors).

Angina

Angina, also known as angina pectoris, is chest pain or pressure, usually due to not enough blood flow to the heart muscle.

Arteriole

An arteriole is a small-diameter blood vessel in the microcirculation that extends and branches out from an artery and leads to capillaries.

Artery

An artery (plural arteries) is a blood vessel that takes blood away from the heart to all parts of the body (tissues, lungs, etc).

Beta-2 adrenergic receptor

The beta-2 adrenergic receptor (β2 adrenoreceptor), also known as ADRB2, is a cell membrane-spanning beta-adrenergic receptor that interacts with (binds) epinephrine, a hormone and neurotransmitter (ligand synonym, adrenaline) whose signaling, via a downstream L-type calcium channel interaction, mediates physiologic responses such as smooth muscle relaxation and bronchodilation.

Calcium channel blocker

Calcium channel blockers (CCB), calcium channel antagonists or calcium antagonists are several medications that disrupt the movement of calcium through calcium channels.

Cardiac output

Cardiac output (CO, also denoted by the symbols Q and \dot Q_), is a term used in cardiac physiology that describes the volume of blood being pumped by the heart, in particular by the left or right ventricle, per unit time.

Catecholamine

A catecholamine (CA) is a monoamine, an organic compound that has a catechol (benzene with two hydroxyl side groups at carbons 1 and 2) and a side-chain amine.

Heart arrhythmia

Heart arrhythmia (also known as arrhythmia, dysrhythmia, or irregular heartbeat) is a group of conditions in which the heartbeat is irregular, too fast, or too slow.

Heart failure

Heart failure (HF), often referred to as congestive heart failure (CHF), is when the heart is unable to pump sufficiently to maintain blood flow to meet the body's needs.

Hormone

A hormone (from the Greek participle “ὁρμῶ”, "to set in motion, urge on") is any member of a class of signaling molecules produced by glands in multicellular organisms that are transported by the circulatory system to target distant organs to regulate physiology and behaviour.
