Patent ductus arteriosus can lead to enlargement of the anterior heart, as it can cause enlargement of the left atrium, left ventricle, or anterior ventricle, potentially leading to heart failure, especially altering heart function. If a patient has a patent ductus arteriosus, I personally recommend getting an ECG at a hospital early and then determining a treatment plan. Currently, surgical treatment is advised to improve the condition of reduced heart function. During this time, it is still important to actively and regularly monitor changes in the patient’s blood pressure, heart rate, and pulse. If the heart rate is too fast or blood pressure is elevated, regular hospital visits are necessary for management.

Does a patent ductus arteriosus easily lead to bronchitis?

Patent ductus arteriosus can lead to bronchitis, as this condition can cause recurrent respiratory infections, particularly bronchitis and bronchopneumonia. This is a type of congenital heart disease, and it is recommended that patients undergo regular echocardiography, especially cardiac ultrasound. If the closure of the patent ductus arteriosus is delayed, early surgical treatment is required. This condition can sometimes affect the growth and development of children, and it mainly causes repeated respiratory infections, including bronchitis, particularly issues with pulmonary inflammation, which require early management.

Can patent ductus arteriosus be treated with medication?

The ductus arteriosus is a blood vessel connecting the pulmonary artery to the aorta in the fetal heart, primarily used during the embryonic stage to supply blood from the mother to the heart, thus providing sufficient oxygenated blood for fetal development and growth. Generally, the ductus arteriosus should close automatically within three months after birth. If it remains open for over a year, it may indicate a congenital heart defect known as patent ductus arteriosus. Previously, high doses of aspirin were used to treat this condition, but this treatment was not very effective. Patients with patent ductus arteriosus should instead consider minimally invasive interventional treatments to seal the duct, or surgical ligation can be performed. However, surgical ligation may cause significant trauma or scarring to the patient. The majority of cases with patent ductus arteriosus can be treated using minimally invasive methods.

Why does patent ductus arteriosus cause a decrease in diastolic pressure?

In patients with patent ductus arteriosus, since the aortic pressure is significantly higher than the pulmonary artery pressure throughout the cardiac cycle, there is continuous blood flow from the aorta into the pulmonary artery through the open duct, causing a left-to-right shunt. This increases the blood volume in the pulmonary circulation, causing dilatation of the pulmonary artery and its branches. The blood flow returning to the left heart system also increases, thereby increasing the load on the left heart and causing the left heart to enlarge. Due to the diastolic diversion of blood from the aorta to the pulmonary artery, the peripheral arterial diastolic pressure decreases and the pulse pressure increases.

Does patent ductus arteriosus cause easy sweating?

The arterial duct is prone to sweating. During this period, it is best to advise patients to monitor changes in blood pressure, heart rate, and pulse. Sometimes there may be incidences of rapid heart rate, as this is a type of congenital heart disease. If a patient is prone to respiratory infections, especially pneumonia, this condition can lead to a decrease in resistance. For such patients with weak constitution, they are more likely to sweat. In terms of treatment, early surgical intervention is advised to alleviate the sweating, and preparations should be made early on.

Is it easy to get pneumonia if the arterial duct is not closed?

Because patent ductus arteriosus is a type of congenital disease, particularly congenital heart disease, it is recommended that patients visit a hospital for a cardiac ultrasound. This can help clarify the diagnosis and thus determine the treatment plan. A simple patent ductus arteriosus can sometimes close on its own. For those that do not close or are underdeveloped, surgical treatment can be used to alleviate the current condition. This is important because the disease can easily lead to pneumonia, especially recurrent respiratory infections. Sometimes, there may be developmental anomalies, particularly affecting the growth and changes in the child's height and weight. In these cases, early surgical treatment is still recommended.
