chest pain cardiac arrest vs heart attack

Angina (angina pectoris)

Angina, also known as angina pectoris, is a type of chest pain that occurs when the heart muscle doesn’t receive enough oxygen-rich blood. It is usually caused by narrowed or blocked coronary arteries, which can restrict blood flow to the heart.

Case: A 60-year-old male presents with a history of chest pain, tightness, and discomfort that radiates to the neck and left arm. The pain usually occurs during physical activity or emotional stress and is relieved by rest or medication. He has a medical history of hypertension, hyperlipidemia, and smoking. The patient also reports occasional shortness of breath and fatigue.


Angina is usually caused by atherosclerosis, a buildup of plaque in the coronary arteries that supply blood to the heart. The plaque can cause the arteries to narrow, reducing blood flow to the heart muscle. When the heart muscle doesn’t receive enough oxygen-rich blood, it can lead to chest pain or discomfort.

Signs and Symptoms

The most common symptom of angina is chest pain or discomfort, which is often described as a pressure or tightness in the chest. The pain may also be felt in the neck, jaw, shoulders, back, or arms. Other symptoms may include shortness of breath, sweating, nausea, dizziness, or fatigue.


The diagnosis of angina is usually made based on the patient’s symptoms and medical history. Additional tests may be ordered to confirm the diagnosis or to assess the severity of the condition. These tests may include an electrocardiogram (ECG), a stress test, a chest X-ray, or coronary angiography.


The treatment of angina aims to relieve symptoms, prevent complications, and reduce the risk of heart attack or other cardiovascular events. Treatment options may include lifestyle changes, medications, or invasive procedures such as angioplasty or bypass surgery. Lifestyle changes may include quitting smoking, losing weight, exercising regularly, and eating a healthy diet. Medications may include nitroglycerin, beta-blockers, calcium channel blockers, or antiplatelet agents.
