Heart disease is a complex disease that is manifested by abnormal heart function and damage to the heart structure. The treatment depends on the severity of the illness and the patient's physical condition. People with mild heart disease can control their symptoms and alleviate the disease through medication and lifestyle changes. Patients with moderate to severe heart disease needed to undergo surgery such as heart transplant, bypass surgery, heart valve replacement surgery, and so on. These surgeries were all high-risk surgeries, but the risks could be reduced through strict preoperative preparation and postoperative care. Understanding the specific symptoms and treatment of heart disease when writing a novel can provide strong support for the plot. For example, a brave male protagonist overcame his heart disease and realized his dream through treatment and struggle in the face of difficulties.
