Back ground: Regular exercise training program has been shown to reduce mortality, improve functional capacity and control risk factors in myocardial infarcted patients. Wall motion score index (WMSI) is a strong independent mortality predicator in patient with previous MI AIM: The main objective of this study was to investigate the impact of exercise training on regional left ventricular systolic function, in patients post anterior myocardial infarction. using cardiac magnetic resonance imaging Methods: We recruited twenty-six adult patients on optimal medical therapy one month after an anterior myocardial infarction underwent successful percutaneous coronary intervention (PCI) were assigned to a three-month exercise training program group or to a control group, (control group: n=10, training group: n=16). Symptom limited treadmill exercise (Modified Bruce Protocol) test was done to exercise training group before and repeated after finishing the CR program. Cardiac Magnetic Resonance (CMR) was performed for all patients 4 weeks after PCI and was repeated after completion of the study period that was lasted for 12 weeks. Results: A total number of patients, included 26 (100%) males, assigned to control group n:10 without an exercise mean age 50± 8 years, weigh 84 ±17 kg, height 175±7.7cm and EF was 36.62±14.23 and to training group n:16 with 3-months exercise training program, the mean age, weight, height and EF were 50.19±8.68 years, 82.69±16 kg, 172.81±7.74 cm, 36.62±14.32% respectively While there was significant improvement in EF (P<0.0008), WMSI (P<0.00003) without significant change in LVESV and LVEDV in exercise training group, there was no significant change in EF, WMSI, LVESV and LVEDV in control group. Conclusion: CMR revealed that exercise training in post-myocardial infarction patients could have beneficial effects on LV global and regional function without adversely affecting LV remodeling or causing serious cardiac complications with significant improvement in exercise capacity after 3 months of exercise training program.

The article discusses the use of country-level panel data on per capita gross domestic product and measures of health and education in comparing East Asia's progress to increase incomes with its progress to improve health and education results. It is suggested that East Asia shows to be the only region showing evidence of convergence among developing countries.
