Can patients with heart disease go to high altitudes?

In general, patients with heart disease are not advised to travel to high-altitude areas. The detailed explanation is as follows:

Heart disease comes in various types, such as coronary atherosclerotic heart disease, valvular heart disease, and congenital heart disease. Patients may suffer from myocardial ischemia or cardiac insufficiency. In high-altitude regions, where oxygen levels are lower, these conditions can worsen due to hypoxia, potentially triggering acute cardiac events. Severe cases may lead to pulmonary edema or sudden cardiac death. Therefore, individuals with heart disease should avoid traveling to high-altitude areas without medical consultation. They should regularly undergo appropriate medical evaluations at hospitals to determine the precise diagnosis and severity of their condition, and receive standardized drug therapy accordingly.

In summary, patients with heart disease should avoid high-altitude environments to prevent exacerbation of their condition or life-threatening complications. It is recommended that these patients maintain a healthy diet and regular作息 (daily routine), and strictly adhere to prescribed medications to better manage their condition.
