Key result
In open vascular surgery patients, asymptomatic systolic left ventricular dysfunction was associated with increased 30-day cardiovascular events (OR 2.3; 95% CI 1.4-3.6) and long-term mortality.
Why the study?
Does asymptomatic left ventricular dysfunction predict 30-day cardiovascular events and long-term cardiovascular mortality in patients undergoing vascular surgery?
Population
1,005 consecutive vascular surgery patients (649 open vascular surgery, 356 endovascular surgery)
Comparison
Presence of asymptomatic left ventricular… vs Normal LV function or symptomatic heart failure
Design
Cohort
Follow-up
30 days and long-term

May refine preoperative risk stratification in vascular surgery; leaves open whether screening alters outcomes.

Does asymptomatic left ventricular dysfunction predict 30-day cardiovascular events and long-term cardiovascular mortality in patients undergoing vascular surgery?
Odds Ratio: 2.3 (95% CI 1.4–3.6)
Flu et al. (2010) conducted a cohort in Vascular surgery (n=1,005). Asymptomatic left ventricular dysfunction vs. Absence of asymptomatic left ventricular dysfunction was evaluated on 30-day cardiovascular events (for asymptomatic systolic LV dysfunction in open vascular surgery) (OR 2.3, 95% CI 1.4-3.6). In open vascular surgery patients, asymptomatic systolic left ventricular dysfunction was associated with increased 30-day cardiovascular events (OR 2.3; 95% CI 1.4-3.6) and long-term mortality.
