HCM is diagnosed once other secondary causes of
left ventricular wall thickening (hypertrophy), such as hyperthyroidism, systemic hypertension, aortic stenosis and others have been ruled out.
In middle aged and older cats with HCM, secondary systemic causes of
left ventricular wall thickening should be excluded such as systemic hypertension and hyperthyroidism.
Treatment has been shown to increase
left ventricular wall thickness and improve cardiac output, increasing the ability to engage in high intensity exercise (which is beneficial for both heart health and the secretion of growth hormone by the pituitary gland).
It may be an adaptation that is intended to reduce stress on
the left ventricular wall (Storey & Smith, 2012).
Left ventricular wall diameter: 60.1 mm before surgery; 53.7 mm after surgery.)
HCM is typically characterised by thickening of
the left ventricular walls.
The thickened
left ventricular walls become less flexible which prevents the left ventricle from relaxing or stretching sufficiently to fill with blood from the left atrium.

left ventricular twist due to local damage that extends through the heart
wall.
The sound waves pass through the muscle
walls and provide a gauge of
left ventricular mass (LVM).
Although the primary endpoint was not met, a statistically significant 4 percent improvement was seen in a secondary endpoint,
left ventricular ejection fraction — a measure of how much blood is being pumped out of the
left ventricle — in patients whose STEMIs involved the front
wall of the
left ventricle (the heart's main pumping chamber), he said.
A transthoracic echocardiogram demonstrated an inferior
wall motion abnormality and a
left ventricular ejection fraction of 35 - 45 % (see Figures 2 - 6).
The muscle of the heart strengthens when the muscle on the
left ventricular and septum
wall increases.
However, the end - stage of the disease frequently results in
ventricular wall thinning, as well as decreased myocardial contractility and severe
left atrial enlargement.
A
ventricular septal defect (VSD) is a hole or holes in the
