Association of Systemic Thromboxane Generation With Risk of Developing Heart Failure
Main finding · Incident HFResult — go to the resultHazard ratio 1.81 95% CI 1.38–2.64Authors' conclusion
Systemic thromboxane A2 generation as measured by urinary TXB2-MGFR was significantly associated with HF risk and remained so after accounting for traditional risk factors.
Study context
- Population
- Framingham Heart Study participants without prior heart failure (HF) and with left ventricular ejection fraction (LVEF) ≥55%, irrespective of ASA use
- Participants
- 2,611 participants
- Exposure
- High vs low urinary TXB2-MGFR
- Outcome
- Incident HF
- Follow-up
- Median 14.8 years (Q1-Q3: 12.6-15.7 years)

- HF with preserved LVEF — First HF events with preserved LVEF
- 104 (55.0%)
- HF with reduced LVEF — First HF events with reduced LVEF
- 56 (29.6%)
ASA use and plasma P-selectin
- Neither ASA use nor platelet activation (plasma P-selectin) independently associated with HF risk
