What causes sudden chills and heart discomfort at night, and what should be done?

Sudden chills and heart discomfort at night may be caused by excessive anxiety, gastric ulcer, cardiomyopathy, or other reasons. These symptoms can be improved through general treatment or medication. Specific analysis is as follows:

1. Excessive Anxiety

If a person experiences high stress or excessive anxiety regularly, it may lead to dysfunction of the autonomic nervous system, thereby affecting the body's temperature regulation and normal heart function. It is important to get adequate rest, relax the mind, and engage in outdoor activities to relieve stress.

2. Gastric Ulcer

A gastric ulcer may cause gastrointestinal dysfunction, which in turn affects the body's temperature regulation and normal cardiac function. Patients may take medications such as enteric-coated rabeprazole sodium capsules or amoxicillin capsules under medical guidance.

3. Cardiomyopathy

Cardiomyopathy may lead to cardiovascular disease and insufficient blood supply to the heart, thus impairing normal heart function. Patients may take medications such as isosorbide nitrate tablets or amlodipine besylate tablets under a doctor’s supervision.

In addition to the above causes, such symptoms may also result from coronary atherosclerotic heart disease, hypertension, acute myocardial infarction, or other conditions. If physical discomfort occurs, it should be taken seriously; prompt hospital visits are recommended for thorough evaluation and appropriate treatment.
