Overview

Elevated levels of D-dimer signify activation of the hemostastic and fibrinolytic pathways. D-Dimer has been widely evaluated in its association with adverse outcomes among patients with acute venous thromboembolism (VTE).[1] Elevated D-dimer levels are independently associated with mortality,[2] and this association is particularly strong among patients with a malignancy.[3][4]

D-Dimer in Patients Not Known to Have Either Malignancy or Cardiovascular Disease

Among 17,359 healthy subjects aged more than 35 years who were not known to have either cancer or cardiovascular diseases in the MOLI-SANI cohort and who were followed for an average of 4.2 years, elevated D-dimer was independently associated with increased risk of overall mortality. The incidence of death by quartile of D-dimer were 1.1%, 1.4%, 1.1% and 2.8% for the first, second, third and fourth quartiles respectively. A D-dimer level within the upper quartile (>221 ng/mL) was associated with a higher risk of mortality; in fact, the hazard ratio for death in patients having a D-dimer level within the upper quartile were 2.86%, 1.54% and 1.46% before adjustment for any factors, after adjustment for age and gender and after adjustment for age, gender, smoking, BMI, alcohol intake, hypertension, diabetes or dyslipidemia respectively. Following the stratification of each quartile into tertiles, the hazard ratios for increasing death for the upper three tertiles were 1.06%, 1.45% and 1.97% (p<0.0001) after adjustment for age, gender, smoking, BMI, alcohol intake, hypertension, diabetes and dyslipidemia and 1.01%, 1.38% and 1.86% (p<0.0002) after further adjustment for CRP and WBC.[5]

D-Dimer in Patients Presenting to the Emergency Room

  • Among 366 patients presenting to the emergency department (ED), mortality was higher among patients with a D-dimer > 5500 mg/L (9%) versus that among patients with a D-dimer <1,500 mg/ml (1.1%). The sensitivity and specificity of D-dimer in predicting mortality were 95% and 26% respectively, while the PPV and NPV were 7 % and 99% respectively.[6]
  • Elevated level of D-dimer is an independent predictor of all-cause mortality among patients presenting to the ED following cardiac arrest outside the hospital (odds ratio 5.7, 95% confidence interval 1.22 to 26.69). Among 182 individuals with out-of-hospital cardiac arrest, 79 patients were deceased and were found to have a mean level of D-dimer higher than that of the cardiac arrest survivors.[7]

D-Dimer in Patients with Pulmonary Embolism and Venous Thromboembolism

  • In a meta-analysis of 2,885 pulmonary embolism (PE) patients, elevated D-dimer was associated with short-term mortality (death within 15 to 30 days after VTE) both among all patients (OR:2.76) as well as those with hemodynamic stability (OR: 2.5, post-bias adjustment).[8][9][10][11][12][13] There was no significant between-study heterogeneity (I2=0%).[8]
  • Among 4 studies enrolling 1254 patients, D-dimer was associated with 3-month mortality as well (OR: 4.29); but results were less consistent across studies.[8][6][14][15][13] In one study, D-dimer levels were not associated with mortality after 3 months following VTE. [13]
  • In 2008, high D-dimer levels were incorporated with other markers of PE severity, including location and size of emboli, to evaluate the relationship among various PE prognostic factors. When emboli were centrally located, D-dimer levels were shown to be higher and associated mortality was more significant. In addition, concomitant malignancy, age > 65 years, and diagnosis of in-patient PE were all associated with heightened levels of D-dimer and increased mortality risk. This study suggested that the best cut-off level of D-dimer to predict mortality is more than 3000 ng/mL (OR= 7.29, CI=95%).[11]
  • Data results from RIETE registry also supports the association between high levels of D-dimer and fatality from pulmonary embolism (OR=1.8, CI=95%) as well as higher risk of major bleeding. According to the RIETE registry, a prospective registry of 1707 patients with acute VTE, D-dimer levels ≥ 4200 µg/L were associated with 7% mortality within the first 15 days post-VTE vs. only 2.7% mortality in patients when D-dimer levels were < 1050 µg/L. Patients with elevated D-dimer levels were at more risk of fatal PE and major bleeding than those with D-dimer levels below the described cut-off values in RIETE registry.[12]
  • According to Agterof and colleagues, D-dimer concentration ≥ 3000 µg/ml and pulse rate ≥ 100 bpm were both associated with serious adverse events in the first 10 days among patients with pulmonary embolism. Their findings suggest that it is not recommended to treat patients with PE who have high D-dimer levels or pulse rates as outpatients.[9]
  • In another retrospective study involving 411 patients, elevated D-dimer levels of median = 2947 µg/L was associated with 30-day mortality in normotensive patients vs. patients with D-dimer median value = 1464 µg/L (p=0.02). Nonetheless, neither the importance of D-dimer levels nor that of troponin, which was also studied, nor their combination could outweigh the PE severity index (PESI) score in determining mortality (p<0.0001); but addition of troponin to PESI score was helpful in predicting adequate PESI score for risk stratification.[10]

Optimal Cutpoint D-Dimer Cutpoint for Identifying Increased Risk of Mortality

  • Among 292 hemodynamically stable patients with PE, a D-dimer < 5000 was associated with no in-hospital mortality from PE (0 of 222) while a D-dimer > 5000 ng/mL was associated with a in-hospital mortality from PE of 2.9% (2 of 70)(p = 0.06).[16]
  • Among patients followed for a longer period of time (3 months), there was a 1.1% mortality in patients with median D-dimer levels < 1500 µg/L vs. 9.1% mortality in patients median D-dimer levels > 5500 µg/L (p=0.049).[6]
  • These association between elevated D-Dimer and mortality extends beyond 3 months in the RIETE registry in which a D-dimer ≥ 5000 µg/L was associated with a 2.9 fold increased risk of all cause mortality.[15]

D-Dimer in Patients with Malignancy

Among 300 patients with malignancy, increased D-dimer was as strong or stronger than other biomarkers in its association with higher mortality.[17]

D-Dimer in Patients with Congestive Heart Failure

Among 214 patients with class II to IV congestive heart failure followed for 8.5 months, increased D-dimer was independently associated with increased mortality after adjustment for other heart failure prognostic factors such as age, gender, class of heart failure and renal failure. [18] The correlation between elevated D-dimer more than 1435 ng/ml and mortality in heart failure was also reported in a different study conducted on 174 patients (HR = 3.250, 95% CI 1.647-6.414, P = 0.001).[19]

D-Dimer in Patients with Coronary Artery Disease

  • Among 1057 subjects with known CAD, elevated D-dimer was an independently associated with cardiovascular mortality at 6.6 years of follow-up.[20]
  • Among 6,391 subjects in the Multiethnic Study of Atherosclerosis cohort, elevated D-dimer was found to be associated with cancer mortality and was independently associated with all cause mortality.[21]

D-Dimer in Acute Aortic Dissection

  • High level of D-dimer above 5.67 μg/mL was independently predictive of increased in-hospital mortality among 144 individuals with acute aortic dissection (OR=3.272; 95% CI: 1.638 to 6.535).[22]

D-dimer in Sepsis

  • Increase level of D-dimer is correlated with worsening severity and death. For instance, according to one study higher D-dimer levels were correlated with high risk of 28 day mortality such as the odds ratio are 2.07 (CI=95%) and 3.03 (CI=95%) in patients having a D-dimer level >1180 and >2409 respectively.[23]
  • Higher D-dimer levels were correlated with high risk of 28 day mortality such as the odds ratio are 2.07 (CI=95%) and 3.03 (CI=95%) in patients having a D-dimer level >1180 and >2409 respectively.[23]
