What type of angina is characterized by vasospasms of coronary arteries and causes unpredictable chest pain?

A. Deep vein thrombosis: Deep vein thrombosis (DVT) typically presents with swelling, pain, and tenderness in a specific area of the leg. It does not specifically cause pain that resolves with rest after walking, making it less likely in Mr. Jones's case.

B. Valvular regurgitation: Valvular regurgitation refers to the backward flow of blood due to improper closure of heart valves. This condition primarily affects cardiac function and is not associated with pain in the legs that resolves with rest, which does not correlate with Mr. Jones's symptoms.

C. Varicose veins: Varicose veins can cause discomfort, swelling, and aching in the legs but are not typically characterized by pain that is specifically triggered by walking and resolves with rest. The symptoms of varicose veins usually occur with prolonged standing or sitting rather than exertion.

D. Intermittent claudication: Intermittent claudication is a common symptom of peripheral artery disease (PAD), characterized by muscle pain or cramping in the legs during physical activity, such as walking, that resolves with rest. Mr. Jones's description of pain that occurs while walking and subsides upon stopping aligns with this condition, making it the most appropriate explanation for his symptoms.

A. Fever: Fever is a common sign of pericarditis, often indicating inflammation or infection in the pericardial sac. This symptom is typical in patients with this condition.

B. Mild chest pain: Mild chest pain is a typical symptom of pericarditis. Patients often experience sharp, pleuritic chest pain that may worsen with inspiration or coughing.

C. No evidence of fatigue: Fatigue can be a common symptom in patients with pericarditis due to the body's response to inflammation. Therefore, the absence of fatigue is not typical, making this an appropriate choice.

D. Myalgias: Myalgias or muscle aches can occur in pericarditis as part of the systemic inflammatory response. This symptom is not unusual in patients with this condition.

E. Pericardial friction rub: A pericardial friction rub is a characteristic finding in pericarditis, heard during auscultation. It results from the movement of inflamed pericardial layers against each other.

F. Radiating substernal pain felt in the left shoulder: This type of radiating pain is more characteristic of myocardial ischemia or angina rather than pericarditis. While pericarditis can cause chest pain, it does not typically radiate in the same manner as that seen in cardiac conditions, making this an appropriate choice.
