Unstable Angina, Allergic Angina, and Allergic Myocardial Infarction

Unstable angina, allergic angina, and allergic myocardial infarction.

Myocardial Infarction To the Editor: Nonocclusive thrombus on preexisting plaques, dynamic obstruction, progressive obstruction, inflammation and/or infection, and secondary unstable angina seem to be the 5 not mutually exclusive causes of the unstable angina syndrome. These were suggested in the excellent editorial by E. Braunwald.1 In this editorial, it was pointed out that vasospastic angina...

Complement factors in Acute Myocardial Infarction and Unstable Angina

Background: Coronary artery disease (CAD) is one of the most important and lethal diseases in the world. CAD represents a board spectrum of disease from silent ischemia at one end to sudden cardiac death at the other end. The middle of this spectrum consists of acute myocardial infarction (AMI) and unstable angina pectoris (UA). Recent data show that the inflammatory process plays a major r...

Comparison of serum parathyroid hormone level between patients with acute myocardial infarction, unstable angina, and normal coronary function

Background: Nowadays, cardiovascular diseases (CVDs) are among the most common causes of mortalities worldwide. Parathyroid hormone (PTH) has an important role in the pathogenesis of CVDs. The aim of the current study was to compare serum PTH levels between patients with acute myocardial infarction (MI), unstable angina, and normal coronary function. Methods: This descriptive and analytic stud...

Acute coronary thromboembolization in unstable angina without subsequent myocardial infarction.

A 58 year old man underwent coronary arteriography for unstable angina. During the catheterization, distal embolization of a nonoccluding intracoronary thrombus formed at the site of a subtotal atherosclerotic occlusion of the left anterior descending coronary artery and was documented angiographically. This event, which appears unique, was not associated with subsequent myocardial infarction o...
