Matching included demographics, comorbidities, medication use, and labs: BMI, INR, hemoglobin A1c, troponin, and B-type natriuretic peptide (BNP). Outcomes included 90-days and 1-year systemic complications and mortality.

Both subtypes demonstrated elevated 90-days mortality (OR 7.48 HFpEF; OR 7.43 HFrEF). HFpEF patients had significantly increased risks of MI (OR 13.96), atrial fibrillation (OR 19.31), stroke (OR 9.93), sepsis (OR 10.36), pulmonary embolism (OR 6.55), and AKI (OR 5.25). HFrEF patients showed similar patterns, including atrial fibrillation (OR 17.01), AKI (OR 9.17), and MI (OR 6.91). Cox regression identified age, male sex, elevated BNP, dialysis, chronic kidney disease, and prior MI or stroke as predictors of mortality. Medication analysis revealed ACE inhibitors, ARBs, SGLT2 inhibitors, GLP-1 agonists, and beta blockers as protective, whereas calcium channel blockers and loop diuretics increased risk.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>HF patients undergoing TKA face increased complications and mortality.
