Confirmed Coronary Heart Disease: How Should Patients Exercise Correctly?
Confirmed coronary artery disease, the doctor recommends exercise. Is it beneficial to exercise?
People with low physical activity and lack of sports are more prone to coronary artery disease. Coronary artery disease patients regularly engage in sports, which can lower blood lipids, reduce obesity, improve cardiac function, and enhance quality of life. How should coronary artery disease patients exercise correctly?
Coronary artery disease patients' exercise precautions:
(1) For coronary artery disease patients who independently engage in exercise, without the supervision of medical personnel, the exercise intensity should be 70-75% of the maximum heart rate. Coronary artery disease patients should learn to count their pulse. After exercise, count the pulse for 10 seconds and then multiply the result by 6, which is the maximum heart rate during exercise. This calculated heart rate may be 5-10 beats less than that obtained from a heart rate monitor.
(2) Avoid exercising within 2 hours after a large meal, drinking strong tea or coffee, or within 1 hour after exercise or consuming strong beverages.
(3) Do not drink alcohol or smoke before exercise.
(4) When engaging in high-intensity exercise, coronary artery disease patients should avoid wearing too thick clothing to prevent heat dissipation and increase heart rate.
(5) Avoid using hot water to wash the body immediately after exercise, at least for 15 minutes, and maintain water temperature below 40°C.
(6) Coronary artery disease patients should not exercise in cold environments, exposing the head and chest to cold air will reflexively constrict the coronary arteries, causing angina.
High temperatures and high humidity are also dangerous because exercise increases body temperature, increases peripheral blood flow, leads to sweating, reduces blood volume, and lowers blood pressure. At the same time, metabolic abnormalities increase, leading to increased heart rate and myocardial oxygen consumption, which can cause coronary artery blood supply insufficiency.
(7) Unstable angina patients should not engage in high-intensity exercise and require necessary monitoring. If the patient's stable angina progresses to unstable angina, exercise should be discontinued.
(8) Coronary artery disease patients with poor mental state, depression, or anxiety find it difficult to exercise fully. Nursing staff should provide appropriate psychological treatment.
