Power Walking in Cardiac Patients Who Underwent Post-coronary Angioplasty

Summary

The risk and prevalence of cardiovascular disease in United Arab Emirates (UAE) is high with ischemic heart disease ranks first in terms of major cause of mortality. Large number of patients undergoes coronary angioplasty but very few participate in cardiac rehabilitation because its awareness is not widespread in middle east region.

The objectives was to find the influence of standardized outpatient cardiac rehabilitation program along with power walking on Heart quality of life (Heart QoL), functional exercise capacity, Left Ventricular Ejection Fraction and metabolic equivalent task (MET's) among patients with post coronary angioplasty.

The investigators conducted a randomized clinical trail in out patient physiotherapy department at Thumbay hospitals Dubai, on patients who underwent coronary artery angioplasty. After meeting the inclusion criteria, participants were randomized into standardized outpatient cardiac rehabilitation program along with power walking (intervention group) or standardized outpatient cardiac rehabilitation program (control group).

A 4 weeks of 12 outpatient cardiac rehabilitation sessions consisting of 3 sessions per week was provided to both the groups. Intervention group received standardized outpatient cardiac rehabilitation program along with power walking based on targeted heart rate and weekly steps, whereas control group received only standardized outpatient cardiac rehabilitation program based on American College of Sports Medicine (ACSM) Guidelines.

The investigators measured Quality Of Life (HRQoL) by HeartQoL questionnaire, Exercise Capacity by 6 min walk test (6MWT), Left ventricle Ejection fraction (LVEF) using Echocardiogram, Metabolic Equivalent Task (MET'S) using Symptom-limited exercise stress test and Average number of steps walked daily using step up smartphone Pedometer App.

Interventions

BEHAVIORAL

Power walking

Exercise in the form of Power walking at hospital for 10-20 minutes on treadmill with various exercise intensities. Weekly Steps at home 30 minutes walking with target to reach 1000 steps daily. It is a form of exercise where active upper body movement is performed along with usual walking. It is a fast walking exercise done at a speed of 6 to 8 km/h. During power walking the back is kept straight with the centre of gravity moving from heal, sole, and to hallux. There is active swing back and forth movement of elbow joint with 90 degrees of flexion while walking. Weekly protocol for power walking * Week 1 60-65 % of the target heart rate (THR) 5,000 to 7,499 steps/day * Week 2 65-70 % of the target heart rate (THR) 7,500 to 9,999 steps/day * Week 3 70-75 % of the target heart rate (THR) \>=10,000 steps/day * Week 4 75-80 % of the target heart rate (THR) \>12,500 steps per day
