Highest mean arterial pressure (MAP).

Explanation:

The mean arterial pressure may be defined as the average blood pressure that exists in the individual during the one cardiac cycle. Mean arterial pressure is the ratio of total peripheral resistance / Cardiac output.

Total peripheral resistance is the resistance experienced during the blood flow by the arteries. The MAP is directly proportional to the total peripheral resistance. So, the individual with high TPR ( as explained in the question) has high MAP.
