External counterpulsation: Coronary hemodynamics and use in treatment of patients with stable angina pectoris
Why the study?
Does external pressure counterpulsation improve coronary hemodynamics and exercise angina threshold in patients with stable angina pectoris?
Population
10 patients with stable angina pectoris
Comparison
External pressure counterpulsation vs Baseline (prior to ECP treatment)

Implication
No hemodynamic or symptomatic benefit with ECP in this case; challenges prior positive reports but hypothesis-generating only.
Structured PICO
Does external pressure counterpulsation improve coronary hemodynamics and exercise angina threshold in patients with stable angina pectoris?
P
Population
10 patients with stable angina pectoris
I
Intervention
External pressure counterpulsation (ECP) (4 consecutive 2-hour sessions)
C
Comparator
Baseline (prior to ECP treatment)
O
Outcome
Coronary hemodynamics (left ventricular oxygen consumption, lactate metabolism, coronary sinus blood flow, cardiac index) and exercise angina thresholdsurrogate
External pressure counterpulsation does not significantly improve coronary hemodynamics or provide lasting symptomatic relief in patients with stable angina pectoris.
