Why should patients with coronary heart disease regularly monitor their heart rate?

The incidence of coronary heart disease is increasing year by year, and the risk of complications such as angina pectoris, myocardial infarction and heart failure is higher. Coronary heart disease is caused by myocardial ischemia, hypoxia or necrosis caused by lumen stenosis or occlusion caused by coronary atherosclerosis, and changes in heart rate also affect the severity of myocardial ischemia. Therefore, it is particularly important to control heart rate in patients with coronary heart disease.

Coronary heart disease is mainly coronary artery stenosis, the imbalance of cardiac blood supply and demand caused by insufficient myocardial blood supply, and then angina pectoris and even myocardial infarction. However, the faster the heart rate, the more oxygen is consumed. Angina pectoris, or myocardial infarction, occurs when the heart consumes more oxygen than the blood supply to the blood vessels. Therefore, for patients with coronary heart disease, it is necessary to ensure an appropriately low heart rate. For patients with coronary heart disease, whether receiving coronary stents or conservative drug treatment, it is necessary to pay attention to keeping the heart rate up to standard.

Studies have shown that when the resting heart rate is too high, it is not good for human health, and it will increase the risk of cardiovascular disease and death. In order to reduce the frequency of angina pectoris and myocardial infarction, it is best to control the resting heart rate at 55-60 beats/min. For patients with severe angina pectoris, if no symptoms of bradycardia (such as dizziness, shortness of breath, etc.), the heart rate can also be further reduced to 50 beats/min, but below this value may cause peripheral blood pressure to drop due to insufficient cardiac output, which is prone to ischemic events for the elderly, so the heart rate should not be less than 50 times/min.

The faster the heart rate, the higher the heart rate, the easier it is to aggravate the insufficiency of blood supply. People with coronary heart disease or people with cardiovascular infarction should monitor their heart rate regularly long-term harm. Once the heart rate is too high or too low, you need to seek medical attention immediately.

Plus1Health has a sleep recorder, which can continuously monitor for a long time, monitor heart rate and breathing rate, and automatically generate sleep reports and analysis.
