Association of Systemic Thromboxane Generation With Risk of Developing Heart Failure

J Am Coll CardiolPublished

  • Prospective cohort study

Authors' 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)

Main finding

As reported in the abstract

Hazard ratio

1.81

95% CI 1.38–2.64

P < 0.0001

High TXB2-MGFR vs Low TXB2-MGFR
HR 1.81 (95% CI 1.38–2.64); P < 0.0001
HF occurred overall
189 participants (7.2%)

Observational data: associations, not effects.

Further findings

OutcomeHR (95% CI)P value
HF with preserved LVEF · adjusted for age, sex, ASA use, and CVD1.81 (1.17–2.80)P = 0.0081
HF with reduced LVEF · adjusted for age, sex, ASA use, and CVD2.63 (1.48–4.68)P = 0.0010
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
