Abstract
BACKGROUND Hydroxytyrosol reduces low-density lipoprotein oxidation, contributing to prevention of atherosclerosis progression. METHODS In a prospective, crossover, double-blind, placebo-controlled trial, 30 chronic coronary artery syndrome (CCAS) patients were randomized to 4 capsules/day, containing 412.5 mg olive oil with 2.5 mg hydroxytyrosol (OOHT) each one or placebo for 1 month and then were crossed over to the alternate treatment (placebo or OOHT). We measured (a) perfused boundary region (PBR) of the sublingual arterial microvessels (increased PBR indicates reduced glycocalyx thickness), (b) flow-mediated dilation (FMD), (c) Coronary Flow Reserve (CFR) and markers of LV diastolic function by Doppler echocardiography, (d) pulse wave velocity (PWV), and (e) oxidative stress, inflammatory biomarkers and blood lipids at baseline and after treatment. RESULTS Treatment with OOHT improved PBR, FMD, CFR and PWV compared to baseline (1.8 ± .3 vs. 1.7 ± .4 μm, p = .040, 3.7 ± 2.1 vs. 6.5% ± 2.3%, p < .001, 2.3 ± .4 vs. 2.5 ± .4, p = .030 and 11.1 ± 1.8 vs. 11.8 ± 2.3 m/s, p = .002) while there was no effect after placebo (p = NS). No effect of OOHT treatment was observed on blood pressure. There was a parallel improvement of E' of the mitral annulus and deceleration time of the E wave of mitral inflow after OOHT (p < .05) but not after placebo. Compared to baseline, treatment with OOHT reduced malondialdehyde, a marker of lipid peroxidation, oxidized LDL, triglycerides, PCSK9 and CRP blood levels (p < .05) in contrast to placebo. CONCLUSIONS Hydroxytyrosol-enriched olive oil may have beneficial effects on endothelial, arterial and LV diastolic function likely by reducing oxidative and inflammatory burden in CCAS, though further studies are needed to confirm this mechanism.

Abstract
Introduction COVID-19 patients present impaired subclinical markers of cardiovascular and endothelial function. Subclinical myocardial and vascular dysfunction during COVID-19 disease have been associated with worse outcomes and higher mortality risk. Purpose We investigated the effect of COVID-19 infection on markers of endothelial, vascular and myocardial function at four and twelve months after the infection Methods We recruited 70 patients who were examined in a dedicated post-COVID-19 outpatient clinic during a scheduled follow-up visit at four and twelve months after a confirmed COVID-19 infection and 70 healthy individuals with similar clinical characteristics. At four and twelve months we measured (i) perfused boundary region (PBR) of the sublingual arterial microvessels (increased PBR indicates reduced endothelial glycocalyx thickness), (ii) flow-mediated dilatation (FMD), (iii) coronary flow reserve (CFR) by Doppler echocardiography, (iv) pulse wave velocity (PWV) and central systolic blood pressure (cSBP), (v) global left and right ventricular longitudinal strain (GLS), (vi) myocardial global work index (GWI) global constructive work (GCW), global wasted work (GWW) and the myocardial global work efficiency (GWE) and v) malondialdehyde (MDA), an oxidative stress marker. Results At four months, COVID-19 patients displayed higher values of PBR5–25 compared to control group (p<0.001) which increased at twelve months (p<0.001). FMD, PWV and cSBP values were similar between 4 and 12 months (p>0.05 for all the comparisons) and higher than those in controls (p<0.001, p=0.057, p=0.003 respectively). At four months, COVID-19 patients presented impaired CFR and LVGLS values which were improved at twelve months (p=0.002, p=0.069 respectively), though remained impaired compared to controls (p=0.003 for all the comparisons). At four months, COVID-19 patients had impaired RVGLS values which were significantly improved at twelve months (p=0.001,) and showed no statistically significant difference compared to controls (p>0.05). COVID-19 patients at four months display higher myocardial wasted work and decreased myocardial efficiency compared to controls (p=0.01, p=0.006 respectively). There was a modest improvement in GWW and GWE at twelve months,(p=0.043, p=0.001, respectively); however, these markers remained impaired compared to controls (p>0.05). At four months, MDA was higher in COVID-19 patients compared to control group and significantly decreased at twelve months (p<0.001); however, these values remain higher than in controls (p=0.002) (Table 1). Conclusions SARS-CoV-2 causes endothelial and cardiovascular dysfunction which are partially restored at twelve months after the infection. Funding Acknowledgement Type of funding sources: None.
