Aims To examine the efficacy and safety of direct oral anticoagulants (DOAC) versus low molecular weight heparin (LMWH) in patients with cancer-related venous thrombo-embolism (VTE). Methods and Results An electronic search of MEDLINE, SCOPUS and COCHRANE without language restrictions was performed through April 2020 for randomized controlled trials that compared the effects of DOACs versus LMWH on patients with cancer-related VTE. Summary estimates were reported using random effects model. The main efficacy outcome was VTE recurrence while the main safety outcome was major bleeding events. The final analysis included 4 randomized trials with a total of 2,907 patients. The weighted mean follow-up was 6.1 months. Compared with LMWH, DOACs were associated with lower risk of VTE recurrence (5.7% vs. 9.1%, risk ratio [RR] 0.62; 95% confidence interval [CI] 0.44 to 0.87; P = 0.01), driven by lower deep venous thrombosis (P = 0.02). There was no difference between DOACs and LMWH in major bleeding events (4.8% vs. 3.6%, RR 1.33; 95% CI 0.84 to 2.11; P = 0.23). The incidence of all-cause mortality was similar (RR 0.99; 95% CI 0.84 to 1.16; P = 0.91). Subgroup analysis suggested no differences according to the type of DOAC in recurrent VTE or major bleeding (Pinteraction= 0.53 and Pinteraction= 0.11, respectively). Conclusion Among patients with cancer-related VTE, DOACs were associated with lower risk of VTE recurrence and similar risk of major bleeding compared with LMWH. Future studies examining the subset of cancer patients who drive the most benefit are encouraged.

Objective: Acute myocardial infarction (AMI) is the main cause of cardiovascular events worldwide. AMI commonly occurs in elderly patients because of atherosclerotic process related to common risk factors. Consequently, the rupture of atheromatous plaque with deleterious sequela is the common etiology of the disease. However, there are less studied etiological factors in youth compared with the usual population. Therefore, this study aimed to examine the risk profile of Egyptian youth presenting with AMI. Methods: A study was conducted in 106 patients aged ≤45 years admitted with AMI in our university hospital to explore their clinical profile risk factors. Results: In the study, 71 (67%) and 35 (33%) patients presented with ST elevation myocardial infarction (STEMI) and non-STEMI (NSTEMI). Anterior wall MI was predominant in 49 patients (46.2%). Moreover, 93 patients (88%) were smokers, 31 (29.2%) used tramadol, 43 (40.6%) smoked cannabis, 50 (47.2%) had poor sleeping habits, 29 (27.4%) had high stress levels, 37 (34.9%) had hypertension, and 22 (20.8%) had diabetes. Twenty (18.9%) patients had a family history of premature coronary artery disease. High and low high-density lipoprotein (HDL) levels were observed in 20 (18.9%) and 47 (44.3%) patients, respectively. The left anterior descending artery (LAD) was involved in 56% of the studied population associated with tramadol use. A significant association was found between both tramadol use and cannabis smoking and presence of heavy thrombus burden on coronary angiography. Conclusion: AMI in Egyptian youth was predominantly observed in men, with anterior STEMI as the most common presentation. Cannabis and tramadol addiction were high risk factors for AMI in Egyptian youth.

The presence of comorbid cardiovascular disease (CVD) in patients with chronic obstructive pulmonary disease (COPD) can result in unfavorable outcomes, ranging from deterioration in quality of life to increases in all-cause and cardiovascular mortality. Moreover, cardiovascular events are major cause of hospitalization in patients with COPD and contributing significantly to the economic burden of the disease. Despite the acknowledgment of the prognostic significance of CVD comorbidity in COPD patients, CVD remains underrecognized and undertreated in this patient population. In this article, we address the current knowledge about the estimated prevalence, pathophysiologic association, as well as important considerations in the diagnosis and management of CVD in COPD patients.
