Insights
Carpal tunnel release surgery increases heart failure risk. Patients undergoing carpal tunnel surgery had a higher incidence of heart failure (HF) compared to those who did not have surgery.
Area of Science:
- Cardiology
- Neurology
- Surgical Outcomes
Background:
- Previous studies suggest a link between carpal tunnel syndrome (CTS) and heart failure (HF).
- Amyloid deposition in CTS may precede amyloid cardiomyopathy.
- A potential prodromal relationship between CTS and HF warrants investigation.
Purpose of the Study:
- To investigate the hypothesis that patients undergoing carpal tunnel release surgery have an increased risk of developing heart failure.
- To compare the incidence of HF in patients who underwent carpal tunnel surgery versus those who did not.
Main Methods:
- Utilized the TriNetX database to identify patients with carpal tunnel syndrome (CTS).
- Included patients who underwent surgical treatment (endoscopic or open carpal tunnel release).
- Propensity score matching adjusted for demographics and comorbidities; primary outcome was heart failure (HF).
Main Results:
- The incidence of HF in patients after carpal tunnel release was 3.49% at 5 years, increasing to 7.102% at 20 years.
- Surgical patients showed a statistically significant increased risk ratio (RR) for HF (1.129) at five years post-surgery (P < .0001).
- The risk difference for HF peaked at 2.007% at 20 years, with an RR of 1.369 compared to nonsurgical controls.
Conclusions:
- Patients undergoing carpal tunnel release surgery have a significantly higher likelihood of developing heart failure compared to matched nonsurgical controls.
- The study highlights an increased association between CTS and HF, exceeding general population rates.
- Hand surgeons play a vital role in early identification of HF risk in CTS patients, prompting cardiovascular assessment.
Purpose:
Previous literature suggests a relationship between carpal tunnel syndrome (CTS) and heart failure (HF), indicating that patients with CTS are more likely to experience cardiomyopathy. Amyloid deposition leading to CTS may be prodromal for the development of amyloid cardiomyopathy. We hypothesized that patients undergoing surgery for CTS would have an increased risk of HF compared to those who did not undergo surgery.
Methods:
The TriNetX database was queried using the primary ICD-10 code for CTS to identify patients. Patients were included if they had surgical treatment for CTS, reported as endoscopic or open carpal tunnel release, or median nerve release. The primary outcome was HF. Propensity scoring adjusted for demographics and comorbidities. Statistical significance was set at P < .05, and odds ratios were calculated at 95% confidence intervals (CI).
Results:
The incidence of HF in patients who underwent carpal tunnel release was 3.49%, 5.98%, 6.947%, and 7.102% at 5, 10, 15, and 20 years after surgery. Compared to nonsurgical patients, the risk difference of 0.399 (95% CI, 0.202-0.596) became statistically significant at five years (P < .0001) with an increased risk ratio (RR) of 1.129 (95% CI, 1.0063-1.198) for surgical patients. The risk difference peaked at 2.007% (95% CI, 1.744-2.27) at the 20-year mark with an RR of 1.369 (95% CI, 1.311-1.456).
Conclusions:
This study demonstrates that patients who underwent carpal tunnel release were more likely to experience HF than nonsurgical matched controls. It also showed an increased association with CTS and HF compared to HF progression in the general population In CTS patients with a higher risk of heart failure, hand surgeons can have a crucial role in early identification and facilitating further cardiovascular assessment.
