Implication

May guide differential vascular phenotyping in hypertension versus hypercholesterolemia; leaves open causal and prognostic implications.

Key Points

To evaluate the specific structural and dynamic impacts of arterial hypertension and hypercholesterolemia on elastic arteries and left ventricular stiffness.
Evaluated 100 adult participants divided into five cohorts of 20: healthy young controls (27 ± 4 years), healthy adults (46 ± 9 years), normotensive hypercholesterolemic adults (45 ± 12 years; cholesterol > 239 mg/dl), hypertensive normocholesterolemic adults (56 ± 13 years), and hypertensive hypercholesterolemic adults (56 ± 9 years).
Calculated vascular stiffness using pressure-to-volume change ratios (delta P/delta V) in the aorta, carotid, and brachial arteries, assessed transmitral A/E flow and peak velocity using Doppler ultrasound, and graded carotid atherosclerosis severity from 0 to 2.
Vascular and left ventricular stiffness were increased in hypertensive patients regardless of whether hypercholesterolemia was present.
Carotid atherosclerotic lesions and severity scores were higher in hypercholesterolemic patients, with the greatest reduction in Doppler blood flow velocity occurring when hypertension and hypercholesterolemia coexisted.

Structured PICO

Population

100 individuals divided into 5 groups of 20: healthy young (mean age 27), healthy adults (mean age 46), normotensive hypercholesterolemic adults (mean age 45, cholesterol > 239 mg/dl), hypertensive normocholesterolemic adults (mean age 56), and hypertensive hypercholesterolemic adults (mean age 56).

Outcome

Vascular dynamics and structure of the elastic arteries (arterial pressure divided by volume change of aorta, carotid, and brachial arteries; A/E index; maximum velocity flow; carotid atherosclerosis score)surrogate

Arterial hypertension is primarily associated with increased vascular and left ventricular stiffness, whereas hypercholesterolemia drives the development and severity of carotid atherosclerosis.
