A 65-year-old man is brought to the emergency department due to chest pain that started 12 hours ago while watching television. The patient describes the pain as “heavy pressure” located in the center of the chest that radiates up to the neck and jaw. He states that the pain has waxed and waned, although he has felt some relief from taking sublingual nitroglycerin. Medical history is significant for coronary artery disease, stable angina, hyperlipidemia, and type 2 diabetes mellitus. The patient’s temperature is 36.7°C (98.0°F), pulse is 110/min, respirations are 24/min, and blood pressure is 135/93 mmHg. Pulse oximetry on room air shows an oxygen saturation of 97%. Chest x-ray shows no abnormalities, cardiac enzymes are negative, and ECG shows ST-segment depression in the anterior leads. Which of the following is the most likely diagnosis?

Key Takeaways

Unstable angina is a serious medical condition that requires immediate attention, as it is considered a medical emergency. It occurs when the blood flow to the heart is suddenly blocked or reduced, leading to chest pain or discomfort. Unstable angina is different from stable angina, which usually occurs during physical activity or emotional stress and goes away with rest or medication. Unlike stable angina, unstable angina is unpredictable and can occur at any time, even at rest. Nitroglycerin can provide temporary relief, but it does not address the underlying cause of the condition. Treatment for unstable angina may include medications, lifestyle changes, and medical procedures such as angioplasty or coronary artery bypass surgery.
