Question
What does the term **angina pectoris** literally mean in Latin, and what sensation does it describe?
Answer
**Angere** (to strangle/choke) + **pectoris** (chest) — describes a strangling or choking sensation in the chest.
Question
What is the key difference between **stable angina** and **unstable angina** in terms of triggers and relief?
Answer
**Stable angina** is triggered by exertion/excitement and relieved by rest or nitrates; **unstable angina** is caused by thrombi, occurs at rest, and is not relieved by rest or nitrates.
Question
Name two typical symptoms of angina pectoris involving the chest and respiratory system.
Answer
Heaviness on the chest and dyspnea (shortness of breath).
Question
What is **Prinzmetal angina**, and how does its cause differ from stable and unstable angina?
Answer
A variant caused by coronary artery **vasospasm**, not by atherosclerotic plaques or thrombi; it shows an elevated ST segment on ECG.
Question
How do **atherosclerotic plaques** contribute to angina by affecting blood pressure and vessel integrity?
Answer
Plaques narrow the lumen, increasing total peripheral resistance (\uparrowTPR), which raises blood pressure and can rupture the vessel.
