NCT06079008

Brief Summary

The goal of this observational study is to learn about the association between cardiac valve calcification and the 1-year mortality after lower-extremity amputation in diabetic patients. Diabetic patients requiring lower-extremity amputation were retrospectively studied. Preoperative detailed anamnesis was taken. Cardiac valve calcification was assessed using echocardiography at baseline. One-year follow-up was conducted and included clinical visits, hospital record assessment, and telephone reviews to obtain the survival status of patients. Researchers compare the survival group to the mortality group to study the relationship between the cardiac valve calcification and mortality.

Sampling MethodNon-Probability Sample
Study Population

The investigator recruited consecutive patients who were admitted to the Sun Yat-sen Memorial Hospital for diabetic foot ulcers that needed amputation surgery between July 2017 and March 2021 and were followed up for 1 year after amputation surgery

You may qualify if:

  • Had echocardiography at baseline
  • With diabetic foot ulcers that required amputation after orthopedist's assessment

You may not qualify if:

  • Fractures due to traumatic reasons that required extremity amputation
  • Amputation level below the ankle
  • Severe sepsis that required vasoactive agent treatment
  • Rheumatic heart disease
  • Heart valve surgery history
