Coffee is one of the most widely consumed beverages globally. A substantial number of observational data suggest an inverse relationship between coffee consumption and the risk for cardiovascular disease. The basis for this association is not clear. In this review, we specifically study the impact of coffee on inflammatory biomarkers as one potential mechanistic basis for this observation. Our objective was to systematically review randomized controlled trials that examined the effects of coffee consumption on selected cardiovascular biomarkers. ⋯ Based on our systematic review of randomized controlled studies, we cannot confidently conclude that an anti-inflammatory effect of coffee is a major contributing factor to the lower all-cause mortality reported in observational studies.

The association between coronavirus disease 2019 (COVID-19) and hypercoagulability has been extensively described, and pulmonary embolism is a recognized complication of COVID-19. Currently, the need for computed tomography pulmonary angiogram (CTPA) relies on the Wells score and serum D-dimer levels. However, because COVID-19 patients have a different thrombotic and inflammatory milieu, the usefulness of the Wells score deserves further exploration for this patient population. We aimed to explore the ability of the Wells score to predict pulmonary embolism in patients with COVID-19. ⋯ Of 459 patients with COVID-19, 64 had a CTPA and 12 (19%) had evidence of pulmonary embolism. Previous or current evidence of deep vein thrombosis, a Wells score above 4 points, and serum D-dimer levels 5 times above age-adjusted upper normal values were associated with pulmonary embolism. However, only 33% of patients with pulmonary embolism had a Wells score of 4 points or higher. The area under the curve of the receiver operating characteristic showed non-discriminating values (0.54) CONCLUSIONS: Although a Wells score of 4 or more points predicted pulmonary embolism in our cohort, the outcome can be present even with lower scores.
