What’s angina pectoris?  

Angina pectoris may be the healthcare term for chest discomfort or soreness because of coronary heart disease.  Angina is really a symptom of a situation known as myocardial ischemia.  It happens when the heart muscle (myocardium) does not get as much bloodstream (therefore as a lot oxygen) since it needs. This usually occurs simply because one or more of the heart’s arteries (coronary blood vessels that provide blood to the heart muscle) is narrowed or blocked.  Insufficient bloodstream supply is known as ischemia.
