ABSTRACT
BACKGROUND: To compare the severity of pulmonary embolism (PE) and the long-term complications between patients with and without COVID-19, and to investigate whether the tools for risk stratification of death are valid in this population. METHODS: We retrospectively included hospitalized patients with PE from 1 January 2016 to 31 December 2022. Comparisons for acute episode characteristics, risk stratification of the PE, outcomes, and long-term complications were made between COVID and non-COVID patients. RESULTS: We analyzed 116 (27.5%) COVID patients and 305 (72.4%) non-COVID patients. In patients with COVID-19, the traditional risk factors for PE were absent, and the incidence of deep vein thrombosis was lower. COVID patients showed significantly higher lymphocyte count, lactate dehydrogenase, lactic acid, and D-dimer levels. COVID patients had PE of smaller size (12.3% vs. 25.5% main pulmonary artery, 29.8% vs. 37.1% lobar, 44.7% vs. 29.5% segmental and 13.2% vs. 7.9% subsegmental, respectively; p < 0.001), less right ventricular dysfunction (7.7% vs. 17.7%; p = 0.007) and higher sPESI score (1.66 vs. 1.11; p < 0.001). The need for mechanical ventilation was significantly higher in COVID patients (8.6% vs. 1.3%; p < 0.001); However, the in-hospital death was less (5.2% vs. 10.8%; p = 0.074). The incidence of long-term complications was lower in COVID cohort (p < 0.001). PE severity assessed by high sPESI and intermediate and high-risk categories were independently associated with in-hospital mortality in COVID patients. CONCLUSION: The risk of in-hospital mortality and the incidence of long-term complications were lower in COVID-19. The usual tools for risk stratification of PE are valid in COVID patients.

BACKGROUND: Elevated pulse wave velocity is a haemodynamic parameter considered to be a risk factor for the development of cardiovascular alterations, while pulse pressure is a predictor of cardiovascular complications and development of acute renal failure after both cardiac and non-cardiac surgery. Our objective was to determine whether baseline pulse pressure and estimated pulse wave velocity are associated with renal failure and 30-day mortality following colorectal surgery. METHODS: Retrospective observational study. A total of 816 adult patients undergoing elective colorectal surgery were evaluated by performing multivariable logistic regression analysis to determine whether baseline pulse pressure and estimated pulse wave velocity were independently associated with complications, specifically renal failure and 30-day postoperative mortality, and whether pulse pressure and estimated pulse wave velocity thresholds correlated with outcomes. RESULTS: Baseline pulse pressure was 56.00â¯mmHg (45.00;68.00) and estimated pulse wave velocity was 13.16â¯m/s (10.76;14.85). Baseline pulse pressure was not associated with acute renal failure or mortality in the univariate model. Baseline estimated pulse wave velocity was not associated with complications, acute renal failure, or mortality. An estimated pulse wave velocity of 13.78â¯m/s significantly predicted acute renal failure (AUC 0.654 [0.588-0.720]) and mortality (AUC 0.698 [0.600-0.796]). CONCLUSIONS: Neither pulse pressure nor preoperative baseline estimated pulse wave velocity were associated with acute renal failure or postoperative mortality. The preoperative estimated pulse wave velocity threshold of 13.78â¯m/s predicted an increased risk of acute renal failure and postoperative mortality.
