Objective-To test whether very early resumption of ambulation after fe
moral cardiac catheterisation is feasible and safe in patients with st
able symptoms. Design-Prospective study in a selected group of men and
women undergoing elective cardiac catheterisation, with next day phys
ical inspection. Setting-Inpatient study. Subjects-Two hundred consecu
tive ambulant patients submitted to diagnostic cardiac catheterisation
through the femoral arterial route using 5F catheters: a femoral righ
t heart study was done at the same time in 40 patients (20%). Results-
No patient had major complications during the study. Early ambulation
was not allowed in two patients (1%) because of haematoma formation im
mediately after sheath removal, and in seven (3%) because of poor haem
ostasis or haematoma on inspection at 3 h. Early ambulation was interr
upted in two patients (1%) because of transient arterial hypotension o
n standing in one, and the patient's preference in the other. Of 189 p
atients who resumed full ambulation at 3 h, one (0.5%) had a groin hae
matoma on discharge the next morning. Overall, haematoma 12 h after ca
rdiac catheterisation was present in seven of the 200 patients initial
ly included in the study (3 5%). None of the 191 patients with attempt
ed early mobilisation had signs or symptoms of vascular complications
one month or later after discharge. Conclusion-Supervised resumption o
f ambulation 3 h after uncomplicated cardiac studies with catheters is
safe ambulant patients undergoing elective cardiac catheterisation.
