Abstract
We aimed to study the relation of heart rate recovery after
Exercise to the extent of coronary artery disease and left ventricular

In our study, we selected (56) patients with significant coronary
artery disease as proved by coronary angiography with positive
exercise stress testing, in cardiology department Zagazig University,
,~ during the period from 2001 to 2002.
We aimed to study the correlation of heart rate recovery time to
coronary angiography and left ventricular function measured by echo
Cardiography.
For this objective we studied:
(56) patients (48 male and 8 Female), The mean age was 51 ± 8 years, and
(10) healthy subjects as a control group. Patients divided into three groups.
