Angina can double the incidence of cardiovascular events.

Clinical studies over a nine-year period have shown that angina can increase the incidence of myocardial infarction, death, comorbidities (the proportion of diabetes and kidney disease), and abnormal cardiac function.

So what should I do if I have a stable angina?

Stable angina is characterized by stable angina pectoris also known as exertional angina pectoris.

The main clinical manifestations of pathological chest pain are: 1, local.

Mainly after the sternum, it can affect the anterior region, often radiating to the left shoulder, the left arm has the ring finger and the little finger, or to the neck, pharynx or mandible.

Suddenly often induced by physical labor or emotional agitation, satiety, cold, smoking, tachycardia, shock, etc. may also be induced.

Pain occurs mostly at the time of labor or excitement, not after exhaustion.

Often repeated under similar conditions.

4, duration.

Angina usually lasts from a few minutes to more than ten minutes, mostly 3?
5 minutes, rarely more than half an hour.

What about stable angina?

1, treatment at the time of onset (1) rest immediately after the attack.

(2) drug treatment: can contain a nitrate ester preparation with a faster effect.

1 nitroglycerin 5mg, sublingual, 1?
It started to work in 2 minutes, and the effect disappeared after about half an hour.

2 isosorbide dinitrate 5?
10mg, sublingual, 2?
5 minutes effective, the effect is maintained 2?
3 hours.

2, medication during the rehabilitation period 1 anti-platelet drugs all patients should be taken as long as there is no contraindications for medication.

The optimal dose range for aspirin is 75?
150mg / d.

The main adverse reaction was hypertension or allergic to aspirin, and patients who could not tolerate aspirin could switch to clopidogrel as an alternative treatment.

Long-term use of 2β receptor antagonists can significantly reduce cardiovascular events and mortality.

The dose of the beta receptor antagonist should be individualized, starting with a smaller dose and increasing the dose step by step.
Commonly used drugs include: metoprolol tablets, metoprolol sustained-release tablets and bisoprolol.

Patients with severe bradycardia, convulsions atrioventricular block and acute bronchial episodes, beta receptor replacement agents.

Vascular disease and severe depression in various places are relative contraindications.
