Stratification of a coronary artery

Description:

Stratification of a coronary artery (dissection of a coronary artery) — the rare reason of an acute myocardial infarction or a sudden cardiac death. Develops at the artery wall anguish leading to penetration of blood between its covers. The interrelation of a disease with change of levels of female sex hormones, and also the previous cardiovascular pathology is often noted. In addition, dissection can be caused yatrogenno, for example, at catheterization of a coronary artery.

Symptoms of Stratification of a coronary artery:

Clinical manifestations of stratification of a coronary artery vary depending on stenosis degree — from an asymptomatic current to a sudden cardiac death; dissection can be shown by unstable stenocardia, a myocardial infarction, ventricular arrhythmias. On a clinical picture of dissection symptoms of the combined pathology can be imposed.

Reasons of Stratification of a coronary artery:

Spontaneous stratification of a coronary artery. In 80% of cases spontaneous stratification of a coronary artery is observed at women. There are certificates allowing to assume high interrelation of spontaneous dissection with change of levels of female sex hormones as the majority of cases develops at women in the premenopauzalny period though also other releasers are possible (for example, pregnancy). Also as the reason other basic disease, for example, arterial hypertension in certain cases can serve. The stratification of a coronary artery caused by an exercise stress is possible. However in certain cases the reasons are unevident.

Yatrogeniya. Some cases can be caused by intervention intervention, for example, catheterization of a coronary artery.

Treatment of Stratification of a coronary artery:

Treatment varies depending on a cause of illness and degree of a stenosis. In hard cases, coronary shunting for providing a bypass blood-groove is carried out. In less hard cases stenting and thrombolytic therapy is applied.
