Isolated Systolic Hypertension

Hello, there! Our Therapeutics prof told us that "Isolated Systolic Hypertension" or ISH is somehow "more dangerous" than the Isolated Diastolic Hypertension and it is a more reliable predictor of the development of future cardio-vascular diseases. Why's that? Is it because during systole the heart is contracting and therefore it would "get tired" too much and too quickly if the blood pressure's high? Thanks so much in advance!
