summary

Atrial myocardial infarction has a different clinical process from simple ventricular myocardial infarction, but it is difficult to make a definite diagnosis, and its clinical manifestations are often covered up by concomitant ventricular myocardial infarction, so it has not attracted enough attention. What is atrial myocardial infarction?

What disease is atrial myocardial infarction?

Most of atrial infarction is caused by coronary atherosclerotic heart disease. In addition, chronic obstructive pulmonary disease with pulmonary heart disease, primary pulmonary hypertension, muscular dystrophy, hereditary dyskinesia can also cause atrial infarction. Some patients with normal coronary artery have atrial infarction, which may be caused by hypoxemia and overload of atrial pressure and volume.

Arrhythmia is a common clinical manifestation of atrial infarction, and most of them are supraventricular arrhythmias, the incidence is very high. The incidence of simple ventricular infarction is very low. The arrhythmia of AMI has the characteristics of sudden arrest, including paroxysmal atrial fibrillation, atrial tachycardia, atrial premature contraction, atrial wandering rhythm and so on. Sinus node infarction can lead to sinus quiescence. Early prediction and prevention of these arrhythmias will help to improve the clinical process and prognosis.

1. Patients with simple atrial myocardial infarction should be treated the same as those with ventricular myocardial infarction, no matter whether they have ventricular involvement or not. 2. Because the hemodynamic changes of atrial myocardial infarction are similar to right ventricular infarction, it is beneficial to supplement blood volume under hemodynamic monitoring. 3. For the common supraventricular tachyarrhythmia of atrial myocardial infarction, class Ⅰ a antiarrhythmic drugs should be used for treatment or prevention. Verapamil, digoxin β Receptor blockers can also be used to slow heart rate. 4. Due to the high incidence of embolism, early diagnosis and surgical repair should be made for the serious complications of AMI. 5. It should be noted that pacemaker placement via right subclavian vein is easy to cause atrial rupture, and atrial infarction often occurs on the right side, so catheterization on this side should be considered as a relative contraindication.

matters needing attention

Patients with myocardial infarction should avoid overeating and irritant drinks. Overeating can aggravate myocardial oxygen consumption, aggravate or induce myocardial infarction. Especially after high-fat diet, it is easy to cause the increase of blood lipid, blood viscosity, local blood flow slow, platelet aggregation and coagulation, and induce myocardial infarction. In addition, we should also pay attention to eating foods that are easy to produce flatulence, such as beans, potatoes, green onions, garlic and sweet food, and avoid spicy spicy foods such as strong tea, Baijiu, chili, cocoa powder, coffee and so on.
