Which diagnosis is associated with chest discomfort related to myocardial ischemia?

• A. Pneumonia
• B. Angina
• C. Cervical and thoracic spine disorders
• D. Pulmonary embolism

Answer: (B)

Angina is the chest discomfort caused by myocardial ischemia. It presents as a substernal pressure or squeezing sensation that may radiate to the left arm, neck, jaw, or back. It’s typically brought on by physical exertion or emotional stress and relieved by rest or nitroglycerin, reflecting a temporary mismatch between the heart’s oxygen supply and demand. This differs from the other conditions: pneumonia usually includes infection signs like fever and cough; cervical or thoracic spine disorders cause musculoskeletal chest wall pain that’s often movement-related; pulmonary embolism causes sudden, sharp, pleuritic pain with shortness of breath. So, the diagnosis tied to chest discomfort from myocardial ischemia is angina.
