ABSTRACT

Stroke prophylaxis in atrial fibrillation is an important consideration in patients with cancer. However, there is little consensus on the choice of anticoagulation, due to the numerous difficulties associated with active cancer. Direct oral anticoagulants (DOACs) have been shown to be a promising option. Here, we conduct a simple cross-sectional analysis of 29 cancer patients receiving DOACs for stroke prophylaxis in atrial fibrillation at a tertiary-care institution in London. Our study demonstrates an encouraging efficacy and safety profile of DOACs used in this setting. We conclude by suggesting that, while DOACs may be useful, anticoagulation in cancer patients should continue to be individualised.

ABSTRACT

BACKGROUND: The combination pharmacotherapy of antiplatelet agents, lipid-modifiers, ACE inhibitors/ARBs and beta-blockers are recommended by international guidelines. However, data on effectiveness of the evidence-based combination pharmacotherapy (EBCP) is limited. OBJECTIVES: To determine the effect of EBCP on mortality and Cardiovascular events in patients with Coronary Heart Disease (CHD) or cerebrovascular disease. METHODS: Publications in EMBASE and Medline up to October 2018 were searched for cohort and case-control studies on EBCP for the secondary prevention of cardiovascular disease. The main outcomes were all-cause mortality and major cardiovascular events. Meta-analyses were performed based on random effects models. RESULTS: 21 studies were included. Comparing EBCP to either monotherapy or no therapy, the pooled risk ratios were 0.60 (95% confidence interval 0.55 to 0.66) for all-cause mortality, 0.70 (0.62 to 0.79) for vascular mortality, 0.73 (0.64 to 0.83) for myocardial infarction and 0.79 (0.68 to 0.91) for cerebrovascular events. Optimal EBCP (all 4 classes of drug prescribed) had a risk ratio for all-cause mortality of 0.50 (0.40 to 0.64). This benefit became more dilute as the number of different classes of drug comprising EBCP was decreased-for 3 classes of drug prescribed the risk ratio was 0.58 (0.49 to 0.69) and for 2 classes, the risk ratio was 0.67 (0.60 to 0.76). CONCLUSIONS: EBCP reduces the risk of all-cause mortality and cardiovascular events in patients with CHD or cerebrovascular disease. The different classes of drugs comprising EBCP work in an additive manner, with optimal EBCP conferring the greatest benefit.
