Context:
Vascular changes can be a risk factor for recurrent and new events of stroke. However, few information is known regarding the variables related to aortic pulse wave morphology in stroke individuals.
Objective:
To analyze aortic pulse wave morphology (arterial stiffness indices, hemodynamics and vascular variables) and to compare the paretic and non-paretic sides in individuals after chronic stroke.
Design:
In this cross-sectional study stroke individuals had arterial stiffness indices, hemodynamics and vascular variables assessed with brachial artery oscillometry. T-test (CI95%) was used in order to compare the variables between the paretic and non-paretic sides.
Results:
Twenty individuals were included, 65% men (60.3 SD 16.7 years). The following variables: (mean difference [CI95%]): coefficient of reflection (-2.33 [-4.60 to -0.07]), peak of ejection wave, P1 (5.32 [2.75 to 7.90] and peak of ejection wave, P2 (6.17 [2.55 to 9.78]), central diastolic blood pressure (mean difference [IC95%]): (-3.75 [-6.09 to -1.40]), central systolic blood pressure (-6.17 [-9.74 to -2.59]), mean arterial pressure (-4.46 [-7.08 to -1.84]), peripheral diastolic blood pressure (-3.48 [-5.94 to -1.02]) and peripheral systolic blood pressure (-5.53 [-9.54 to -1.52]) were higher in paretic than non-paretic side. Hemodynamics parameters were similar in both sides.
Conclusions:
In this study we demonstrated, for the first time, that many parameters from aortic pulse wave were higher in paretic compared with non-paretic side in individuals after chronic stroke, suggesting that peripheral vascular changes affect heart-vascular coupling in these individuals.

The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...
