Prevalence and determinants of elevated D-dimer in patients with hypertrophic cardiomyopathy.

Aim: To evaluate D-dimer levels in patients with hypertrophic cardiomyopathy (HCM). Patients & methods: A total of 346 patients with HCM were recruited. Plasma D-dimer was determined by clinical laboratory of our hospital. Left ventricular mass, stroke volume, cardiac output and cardiac index were assessed with cardiovascular magnetic resonance. Results: A total of 36 (10.4%) patients had elevated D-dimer levels. Age, female patients and statin therapy were independently associated with increasing D-dimer levels, and predictors of elevated D-dimer. Conclusion: Patients with HCM may have higher plasma D-dimer levels than subjects without HCM. D-dimer levels in patients with HCM are influenced by age, sex, atrial fibrillation, statin therapy and diastolic blood pressure.
