Effect of PCI revascularization degree on exercise tolerance in patients with multivessel coronary artery disease / 重庆医学

ABSTRACT

Objective To explore the effect of percutaneous coronary intervention(PCI) revascularization degree on exercise tolerance in the patients with multivessel coronary heart disease(CHD).Methods Ninety-three cases of coronary multivessel disease undergoing PCI revascularization and completing the cardiopulmonary exercise testing(CPET) were selected and divided into the complete revascularization group(CR group) and incomplete revascularization group(ICR group).The patients' general condition,co-existence diseases,medication,CHD and vessel lesion situation,echocardiography and CPET results at revascularization and within 1 week of CPET in the two groups were collected.Then the exercise tolerance was evaluated and compared between the two groups.Results The peak metabolic equivalent in the CR group and ICR group were 6.1(3.0-11.0) Mets and 6.3 (3.0-9.0) Mets;the VO2 at anaerobic threshold were 16.3(4.0-23.0) mL · kg-1 · min-1 and 15.9(4.0-26.0) mL · kg-1 · min-1,respectively;the peak VO2 were 21.1(13.0-35.0) mL · kg-1 · min-1 and 21.9(13.0-31.0) mL · kg-1 · min-1,respectively(P=0.919,0.350,0.991).Conclusion For the patients with multivessel CHD receiving ICR,their exercise tolerance is not inferior to those receiving CR.
