Brain natriuretic peptide (BNP), also known as B-type natriuretic peptide, is a hormone secreted by cardiomyocytes in the heart ventricles in response to stretching caused by increased ventricular blood volume. [5] BNP is one of the three natriuretic peptides, in addition to atrial natriuretic peptide and C-type natriuretic peptide ( CNP). [6]
The ACE inhibitor enalapril has also been shown to reduce cardiac cachexia in patients with chronic heart failure. [51] Cachexia is a poor prognostic sign in patients with chronic heart failure. [52] ACE inhibitors are under early investigation for the treatment of frailty and muscle wasting (sarcopenia) in elderly patients without heart ...

The action potential passes along the cell membrane causing the cell to contract, therefore the activity of the sinoatrial node results in a resting heart rate of roughly 60–100 beats per minute. All cardiac muscle cells are electrically linked to one another, by intercalated discs which allow the action potential to pass from one cell to the ...
An increase in heart rate is known as positive chronotropy. The parasympathetic nerves supplying the SA node (in particular the Vagus nerves) originate in the brain. These nerves release a neurotransmitter called acetylcholine (ACh). ACh binds to a receptor called an M2 muscarinic receptor, located on the SA node
Cardiac muscle (also called heart muscle or myocardium) is one of three types of vertebrate muscle tissues, the others being skeletal muscle and smooth muscle. It is an involuntary, striated muscle that constitutes the main tissue of the wall of the heart .
The disease is a type of non-ischemic cardiomyopathy that primarily involves the right ventricle, though cases of exclusive left ventricular disease have been reported. It is characterized by hypokinetic areas involving the free wall of the ventricle, with fibrofatty replacement of the myocardium, with associated arrhythmias often originating ...
