6 characteristics of coronary heart disease

The characteristics of coronary heart disease are as follows

1. Arrhythmia and heart failure type coronary heart disease

Some patients with coronary heart disease do not have chest pain attacks, but only show various arrhythmias or dyspnea as the first symptoms of heart failure. 

Clinically, it is called arrhythmia and heart failure type coronary heart disease.

2. Angina pectoris outside the chest

Angina pectoris occurs outside the chest, and manifests as headache, toothache, sore throat, shoulder pain, and leg pain.

3. Complications of coronary heart disease

If coronary heart disease is combined with other acute diseases, such as diabetic ketoacidosis, acute infection, and surgical emergencies, even if acute myocardial infarction occurs, the symptoms are often misdiagnosed.

4. Myocardial ischemia

Because the elderly often have memory loss, dull senses, and are not good at expressing symptoms.

Therefore, when doing relevant examinations for the elderly, don’t forget to do a routine electrocardiogram. Once evidence of myocardial ischemia is found, drugs such as nitrates should be used for treatment.

5. Cerebrovascular disease

A small number of patients with coronary heart disease, especially those with acute myocardial infarction, only show symptoms of cerebrovascular disease, such as dizziness, limb paralysis, sudden loss of consciousness and convulsions, and other cerebral circulation disorders.

The reason is that during myocardial infarction, cardiac output decreases, resulting in reduced cerebral blood supply, and severe arrhythmia often leads to reduced cerebral blood supply.

6. Gastrointestinal symptoms

Manifested as gastrointestinal symptoms such as upper abdominal distension and discomfort, especially when the pain is severe.

It is often accompanied by nausea and vomiting, which is easily misdiagnosed as acute gastroenteritis, acute cholecystitis, pancreatitis, etc.
