ventricular hypertrophy vs ventricular failure. What's difference?

[Yvainne]

I am confuse with those terms. Can someone explain to me. ?
And also an example or two, so i can imagine how's it?

Thanks !​

Ventricular hypertrophy is the thickening of LV myocytes. This occurs from increased afterload like longstanding hypertension or severe aortic stenosis. It can also be caused by mutations causing myocyte disarray like in hypertrophic cardiomyopathy. A thick ventricle, however does not mean it has failed. There are many people with severe LVH who do not have heart failure. However, with significant thickness, you can have diastolic dysfunction which leads to elevated filling pressures (and so called heart failure which is distinct from ventricular failure).

The term "venticular failure" usually is used to describe systolic failure of the left ventricle. This can be from many reasons including ischemia (MI), longstanding alcohol or cocaine, idiopathic/familial, and many others.

The term 'heart failure' denotes either that the ventricle is unable to pump enough blood to meet the body's demands or that it has to do so at high filling pressures- this can encompass heart failure from systolic dysfunction, diastolic dysfunction or valvular dysfunction.

Thank you so much for the great explanation.
