What is included in Acute Coronary Syn- drome (ACS)? What is unstable angina? What are the 2 types of unstable angina? Prizmetal's Angina is also known as? What is the pathophysiology of Prinzmet- al's angina and when does this usually occur? Prinzmetal's Angina is often seen in which population? Most important risk factor for Prinzmet- al's Angina? Symptoms of Prinzmetal's Angina? How long do they last? Received by nitro? EKG characteristics of Prinzmetal's Angina? 1. Unstable Angina 2. NSTEMI 3. STEMI Angina that occurs with diminished ex- ercise (more resting state) - Myocardial oxygen demand > supply **Partial occlusion by thrombi** - MI is total occlusion by thrombi! 1. Unstable 2. Prinzmetal's Variant, Vasospastic, or Atypical Angina Influx of calcium ions into cell leading to vasospasm of the coronary artery **Not exercise induced** Usually happens in early AM and pt. are usually awaken from sleep Younger men (More in Japanese than Caucasion) Cigarette Smoking Sub-sternal chest pain similar to MI that may radiate 5-30 minutes Yes! Relieved by nitro! ST segment elevation over indicative leads only during angina
