Unstable angina pectoris

Unstable angina pectoris is an acute coronary syndrome characterized by unexpected, transient myocardial ischemia that occurs without biochemical evidence of myocardial necrosis It affects the cardiovascular system, most frequently in adults with underlying atherosclerotic coronary artery disease Clinically, it presents as ischemic chest discomfort that occurs at rest or with minimal exertion, represents a new severe onset, or exhibits a crescendo pattern of increasing frequency, duration, or in...

It affects the cardiovascular system, most frequently in adults with underlying atherosclerotic coronary artery disease

Pathophysiologically, it typically stems from the disruption of an unstable atherosclerotic plaque followed by non-occlusive thrombus formation or coronary vasospasm, leading to a sudden reduction in myocardial blood flow

Pathophysiologically, it typically stems from the disruption of an unstable atherosclerotic plaque followed by non-occlusive thrombus formation or coronary vasospasm, leading to a sudden reduction in myocardial blood flow Clinically, it presents as ischemic chest discomfort that occurs at rest or with minimal exertion, represents a new severe onset, or exhibits a crescendo pattern of increasing frequency, duration, or intensity, accompanied by normal cardiac troponin levels and possible transien...
