Prevention of cardiac ischemia in unstable angina

Prevention of cardiac ischemia in unstable angina refers to the therapeutic mitigation of acute or recurrent myocardial oxygen supply-demand mismatch in patients experiencing unstable angina, an acute coronary syndrome This clinical state primarily impacts the cardiovascular system in individuals with underlying coronary artery disease Pathophysiologically, it is triggered by atherosclerotic plaque disruption, platelet activation, and transient or incomplete thrombotic coronary occlusion, leadin...

Prevention of cardiac ischemia in unstable angina refers to the therapeutic mitigation of acute or recurrent myocardial oxygen supply-demand mismatch in patients experiencing unstable angina, an acute coronary syndrome This clinical state primarily impacts the cardiovascular system in individuals with underlying coronary artery disease

Pathophysiologically, it is triggered by atherosclerotic plaque disruption, platelet activation, and transient or incomplete thrombotic coronary occlusion, leading to critical reductions in myocardial perfusion without overt cell necrosis Clinically, it manifests as prolonged rest pain, new-onset severe angina, or accelerating crescendo angina, characterized by transient ischemic electrocardiographic alterations such as ST-segment depression or T-wave inversion in the absence of elevated serum c...

Preventing ischemia in this setting protects vulnerable myocardium and lowers the risk of progression to acute myocardial infarction or life-threatening arrhythmias
