If the patient has a history of mitral valve insufficiency, and if it is not treated timely, the condition will worsen. If the patient develops heart failure, sometimes it is necessary to actively correct the heart failure, because the most serious complication of this disease is heart failure, which is quite severe. Once the patient's heart function changes, especially if the ejection fraction decreases, it can lead to ischemic and hypoxic changes in the patient. In terms of treatment, it is also important to monitor the patient's blood pressure, heart rate, and pulse changes, while actively controlling the heart rate.
