Peripheral vascular resistance. Most established cases of hypertension are associated with an increase in peripheral vascular resistance [5]. These alterations may be related to a functional constriction, the type observed under the influence of circulating or tissue-generated vasoconstrictors, or may be a result of structural alterations in the blood vessel. Solid line indicates values at start of the study [9];

dashed line indicates results after 10 years; dotted line indicates results after 20 years. BP—blood pressure; CI—cardiac index; DAP—diastolic arterial blood pressure; HR—heart rate; MAP—mean arterial pressure; SAP—systolic arterial blood pressure; SI—stroke index; TPRI—total peripheral resistance index; VO2—oxygen consumption.
