Background:
The relationship between alcohol consumption and vascular structure and arterial stiffness is not clear, especially in people diagnosed with persistent COVID. The aim of this study was to evaluate how alcohol use is related to vascular structure and arterial stiffness in adults with persistent COVID.
Methods:
A descriptive cross-sectional study was conducted involving 305 individuals (97 men and 208 women) diagnosed with persistent COVID according to the WHO criteria. Arterial stiffness was assessed by measuring the cardio-ankle vascular index (CAVI) and the brachial-ankle pulse wave velocity (ba-PWV) with a VaSera VS-1500 device, and the carotid-femoral pulse wave velocity (cf-PWV) with a Sphygmocor device. Vascular structure was assessed by measuring carotid intima-media thickness (c-IMT) with a Sonosite Micromax ultrasound unit. Alcohol intake was calculated using a standardized questionnaire and quantified in g/week.
Results:
Mean alcohol intake was 29 ± 53 g/week (men 60 ± 76 g/w and women 15 ± 27 g/w; p < 0.001). Heavy drinkers showed higher levels of c-IMT, cf-PWV, ba-PWV and CAVI than non-drinkers (p < 0.05). The multinomial regression analysis adjusted for sex and lifestyles showed a positive association between heavy drinking and c-IMT and cf-PWV values (β = 1.08 (95% CI 1.01-1.17); β = 1.37 (95% CI 1.04-1.80); ba-PWV and CAVI figures showed a similar trend, without reaching statistical significance.
Conclusions:
The results of this study indicate that high alcohol use in patients with persistent COVID is linked to higher c-IMT and cf-PWV figures than in non-drinkers.

Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...
