Enhanced external counterpulsation (EECP) is a non-invasive outpatient treatment used for angina pectoris. In patients with intractable angina refractory to aggressive surgical and medical treatment, several novel strategies are considered including EECP, transmural laser revascularisation, and spinal cord stimulation. EECP produces an acute haemodynamic effect that is presumed to be similar to...

Twelve patients with stable angina pectoris received a placebo for 7 days and then oral phentolamine for an additional 7 days. Exercise was performed at the conclusion of the 2 drug periods. All of the patients developed angina with the stress of exercise while taking placebos. The average time to develop angina was 208sec. In comparison, 9 of the 12 patients were able to exercise longer after ...

In a prospective study, enhanced external counterpulsation (EECP) was performed for 1 hour each day for 35 days in 47 patients, mean age 61 +/- 8 years, with prior coronary revascularization who had chronic refractory angina pectoris despite antianginal drugs and who were not candidates for further coronary revascularization. Compared with baseline values, EECP significantly improved anginal sy...

ATYPICAL features of location, quality, time course, radiation, precipitating and ameliorating factors of angina pectoris evoke in the clinician a desire for objective evidence to aid in this sometimes difficult diagnosis. Interest in the electrocardiographic response to exercise of subjects with and without angina pectoris is a manifestation of this difficulty. The "two-step" test, introduced ...

INTRODUCTION AND OBJECTIVES The ability of stress echocardiography to provide prognostic information that supplements that obtainable from clinical data and exercise electrocardiography is still controversial. Our aim was to determine whether dobutamine stress echocardiography provides additional information on long-term prognosis after conventional exercise testing has indicated that a patient...

BACKGROUND Enhanced external counterpulsation (EECP) reduces angina and extends time to exercise-induced ischemia in patients with symptomatic coronary disease. One- and two-center studies and a retrospective case series reported that EECP improves myocardial perfusion in stable angina pectoris. We sought to critically evaluate and quantify the effect of EECP on myocardial perfusion. METHODS ...

A svstem of miultiple-lead exeicise electrocardiography has been applied to the study of 107 normal subjects and 67 patients with angina pectoris. The results of this test are compared to those of coronary cinearteriography in 84 patients. In-exercise ECGs gave useful additional information in 59% of the angina patients but were essential for interpretation in 9%. It added considerably to the s...

AIMS Epidural spinal cord stimulation (SCS) provides symptom relief in refractory angina pectoris, but its mechanism of action remains incompletely understood. We studied effects of short-term SCS therapy on myocardial ischaemia tolerance, myocardial perfusion reserve (MPR), and endothelium-mediated vasodilatation induced by cold pressor test (CPT) in patients with refractory angina pectoris. ...
