A cold heart ache, may be physiological factors, may also be coronary heart disease and other diseases. 1. Physiological factors: Cold weather will stimulate the sympathetic nerves of the human body, inducing vasoconstriction and accelerated heart rate in the body, thus causing insufficient blood supply to the myocardium and symptoms of heart pain. 2. Coronary heart disease: it is usually related to abnormal body metabolism, environmental factors, dietary factors, genetic factors and other factors. When the patient is stimulated by cold, it induces an increase in the demand for blood supply in the body, resulting in anterior heart area colic or pressure pain. 3. Myocardial ischemia: when patients are stimulated by cold, it will lead to the slowing down of fluid circulation and cause myocardial ischemia, resulting in symptoms of chest tightness, shortness of breath and pain. Patients should avoid cold stimulation to avoid adverse reactions; if the symptoms are not relieved for a long time, they should go to the hospital in time for examination, and after clarifying the specific causes, choose the appropriate method of treatment under the guidance of the doctor.
