Atherosclerotic Cardiovascular Disease in Inflammatory Bowel Disease: The Role of Chronic Inflammation and Platelet Aggregation.

Background and Objectives: Atherosclerosis is one of inflammatory bowel disease's most significant cardiovascular manifestations. This research aimed to examine the relationship between biochemical, haemostatic, and immune parameters of atherosclerosis and ulcerative colitis patients and its relationship to platelet aggregation. Materials and Methods: A clinical, observational cross-sectional study was performed, during which the tested parameters were compared in the experimental and control groups. The patients were divided into four groups. The first group had 25 patients who had ulcerative colitis and atherosclerosis. The second group included 39 patients with ulcerative colitis without atherosclerosis. The third group comprised 31 patients suffering from atherosclerosis without ulcerative colitis, and the fourth group comprised 25 healthy subjects. Results: In our study, we registered statistically higher levels of inflammatory markers like SE, CRP, Le, fecal calprotectin, TNF-α, and IL-6, as well as the higher value of thrombocytes and thrombocyte aggregation in the group of patients with ulcerative colitis compared to the control group. Lower levels of total cholesterol and LDL were also recorded in patients with ulcerative colitis and atherosclerosis and ulcerative colitis without atherosclerosis compared to healthy control. Triglyceride and remnant cholesterol were higher in patients with ulcerative colitis and atherosclerosis when compared to patients with ulcerative colitis and healthy control but lower than in patients with atherosclerosis only. Conclusions: Several inflammatory markers and platelet aggregation could be good discrimination markers for subjects with ulcerative colitis with the highest risk of atherosclerosis.

Prognostic significance of symptomatic deep vein thrombosis in patients with acute symptomatic pulmonary embolism regarding the European Society of Cardiology mortality risk model.

BACKGROUND: Deep vein thrombosis (DVT) can be symptomatic or asymptomatic in patients with acute pulmonary embolism (PE). The prognostic value of the symptomatic DVT at the presentation regarding the prognosis of PE is unknown. METHODS: Data were extracted from the REgional Pulmonary Embolism Registry (REPER) which enrolled 1604 hospitalized patients after multidetector computed tomography (MDCT) diagnosed symptomatic acute PE. According to the ESC risk model, patients were classified into four subgroups. Patients who had leg edema with or without pain, and patients with leg pain and DVT confirmed by compression ultrasound were considered to have symptomatic DVT. This study aimed to compare all-cause hospital mortality between patients with symptomatic DVT and patients without symptoms or signs of DVT across the PE risk stratums. RESULTS: All-cause mortality in patients with symptomatic DVT compared to those who had no symptoms or signs of DVT were 2/196 (1.0%) vs. 11/316 (3.5%), P=0.145, 4/129 (3.1%) vs. 17/228 (7.5%), P=0.106, 14/196 (7.1%) vs. 54/290 (18.6%), P<0.001 and 16/55 (29.1%) vs. 51/139 (36.7%), P=0.402 in patients with low, intermediate-low, intermediate-high and high-risk PE, respectively. In multivariate analysis symptomatic DVT was associated with decreased in-hospital mortality only in patients with intermediate-high PE (OR 0.320, 95%CI 0.164-0.627; P=0.001). Intermediate-high risk PE patients with symptomatic DVT who were treated with thrombolysis had significantly lower hospital mortality than patients without symptoms or signs of DVT (2.2% vs. 11.4%, P=0.003). CONCLUSIONS: Intermediate-high risk PE patients with symptomatic DVT at presentation may benefit from thrombolysis and have lower hospital all-cause mortality in such circumstances.
