The main clinical types of coronary heart disease

Because of the location of coronary artery disease, the different scope and extent of this disease have different clinical characteristics may generally be divided into five types. 1, occult or asymptomatic coronary heart disease, asymptomatic, but there myocardial ischemia electrocardiogram changes. Myocardial unorganized morphological changes. 2, angina attack of a sternum pain for the time cardiomyopathy caused by the insufficiency. Myocardial more unorganized morphological changes. 3, severe symptoms of myocardial infarction, coronary artery obstruction, acute myocardial ischemia caused by necrosis. 4, ischemic cardiomyopathy caused by the long-term myocardial ischemia gradually myocardial fibrosis, in the past known as myocardial fibrosis or myocardial sclerosis. Increased performance for the heart, heart failure and (or) arrhythmia. 5, sudden death and sudden cardiac death Poly stops, mostly in local cardiac electrophysiology disordered or pacing, conduction occurred obstacles caused by the severe arrhythmia. In recent years been raised acute coronary syndrome word that due to acute coronary changes suddenly reduced blood flow, cause unstable angina, acute myocardial infarction or sudden death.
