Coronary heart disease patients can do some relaxing and soothing exercises to strengthen the body, shaking hands is also possible. Coronary heart disease, the full name of coronary atherosclerotic heart disease, refers to the atherosclerosis of the coronary arteries, resulting in coronary artery stenosis or blockage, resulting in ischemia of the heart disease. Strenuous exercise will increase the load on the heart, increase the oxygen consumption of the heart muscle, thus aggravating coronary heart disease, and in severe cases can lead to myocardial infarction. In daily life, small exercise will not increase the heart load, but also can improve collateral circulation, play a role in strengthening the body. Exercises such as tai chi, yoga and stretching activities are also suitable for patients with coronary heart disease. Exercise is only an adjunct to the treatment of coronary heart disease. If coronary heart disease has been diagnosed and exercise does not improve the coronary blood supply, please actively seek medical treatment.
