relative ischemia

What is "relative ischemia" in patients with severe left ventricular hypertrophy?

The distribution of the coronary arteries in the myocardium runs from the epicardium inwards. If hypertrophy is severe, the coronary arteries can no longer ensure a sufficient supply of oxygen to the entire width of the wall. Relative ischemia can occur. In severe hypertrophy, this ischemia can even lead to a connective tissue transformation of the heart muscle, that is to myocardial fibrosis.
