Ineffective peripheral tissue perfusion: Clinical validation in patients with hypertensive cardiomiopathy.
OBJECTIVE
To validate defining characteristics of ineffective peripheral tissue perfusion using vasomotor function assessment.


METHODS
Twenty-four patients with hypertensive cardiomiopathy were evaluated for 18 defining characteristics of ineffective peripheral tissue perfusion and underwent vasomotor function assessment with induction of reactive hyperemia, intra-arterial infusion of acetylcholine, and pulse wave velocity measurement. The Student's t test and Kruskall-Wallis test were used to assess the significance of relationships between defining characteristics and vasomotor function data.


RESULTS
Diminished lower extremity pulses were associated with diminished forearm blood flow during acetylcholine infusion; left ventricular overload, intermittent claudication, and diminished skin moisture were associated with elevated pulse wave velocity values.


CONCLUSIONS
The defining characteristics of ineffective peripheral tissue perfusion were highly associated with vasomotor function data as "gold standards" for that diagnosis.


CONCLUSIONS
Nurses should be able to accurately assess diminished lower extremity pulses, intermittent claudication, and diminished skin moisture as relevant characteristics of ineffective peripheral tissue perfusion in patients with hypertensive cardiomiopathy.
