ObjectiveTo observe the effect of square physical fitness exercise on the indexes of disease conditions, biology and blood lipids in patients with coronary heart disease (CHD).Methods125 CHD patients were divided into the exercise group (77 cases, taking part in the square physical fitness exercise) and control group (48 cases, not taking part in the square physical fitness exercise). The indexes of biology, disease conditions and blood lipids of all patients in two groups were tested.ResultsAfter exercise, the body mass, body mass index, waist circumference, numbers of ischemia attacks and duration of ischemia attack in patients of the exercise group were obviously lower than those before exercise ( P<0.05～0.01) and also lower than that of the control group ( P<0.05); the average levels of total cholesterol (TC), triglyceride (TG) and low density lipoprotein cholesterol (LDL-C) in serum decreased and high density lipoprotein cholesterol (HDL-C) increased significantly compared with that before exercise ( P<0.05～0.01), TG, LDL-C were also lower than that of the control group ( P<0.05). In the control group, only indexes of numbers of ischemia attacks, duration of ischemia attack and TG were lower than that in the first test ( P<0.05).ConclusionSquare physical fitness exercise can improve the indexes of disease conditions, biology and blood lipids.
