Multicenter Study Comparative Study
Comparative study on risk factors and early outcome of symptomatic distal versus proximal deep vein thrombosis: results from the OPTIMEV study.
There is a lack of consensus on the value of detecting and treating symptomatic isolated distal deep-vein thrombosis (DVT) of the lower limbs. In our study, we compared the risk factors and outcomes in patients with isolated symptomatic distal DVT with those with proximal symptomatic DVT. We analysed the data of patients with objectively confirmed symptomatic isolated DVT enrolled in the national (France), multicenter, prospective OPTIMEV study. ⋯ However, the mortality rate was significantly higher (p < 0.01) in patients with proximal DVT (8.0%) than in those with isolated distal DVT (4.4%). Symptomatic isolated distal DVT differs from symptomatic proximal DVT both in terms of risk factors and clinical outcome. Whether these differences should influence the clinical management of these two events remains to be determined.

Red cell distribution width (RDW) has been shown to be an independent predictor of mortality in patients with coronary artery disease and in patients with heart failure. The current study evaluated the prognostic utility of RDW in patients undergoing percutaneous coronary intervention (PCI). We evaluated 859 patients who underwent PCI during January 2003 to August 2005. ⋯ For patients with Hgb > or = 10.4 to <12.7, HR for death in patients with high RDW relative to low RDW was 5.2 (95% confidence intervals [CI]: 2.0-13.3). For patients with Hgb > or = 12.7, HR for death in patients with high RDW relative to low RDW was 8.6 (CI:2.8-28.6). Higher RDW was a strong and independent predictor of long-term mortality in patients undergoing PCI who were not anaemic at baseline.
