In unstable angina, symptoms related to decreased blood flow to the heart may appear on rest or on minimal exertion. [4] The symptoms can last longer than those in stable angina, can be resistant to rest or medicine, and can get worse over time. [7] [8] The cardinal symptom of critically decreased blood flow to the heart is chest pain ...
The primary factor differentiating unstable angina from stable angina (other than symptoms) is the underlying pathophysiology of the atherosclerosis. The pathophysiology of unstable angina is the reduction of coronary blood flow due to transient platelet aggregation on apparently normal endothelium, coronary artery spasms, or coronary thrombosis.
[8] [9] Previously, the word "atypical" was used to describe chest pain not typically heart-related, however, this word is not recommended and has been replaced by "noncardiac" to describe chest pain that indicate a low likelihood of heart-related pain. [9] In unstable angina, symptoms may appear on rest or on minimal exertion. [6]
Jaw or neck pain with exertion. Angina—the technical name for chest tightness—can spread to the jaw or neck. It’s typically triggered by exertion, like walking uphill, or emotional stress ...
All right, as a quick recap…. Angina pectoris is chest pain caused by reduced blood flow resulting in a lack of oxygen in the heart muscle. There are three types: stable angina, unstable angina, and vasospastic angina. Rest tends to relieve stable angina, but not the other two types, and all three can be treated with nitroglycerin.
CAD can cause stable angina, unstable angina, myocardial ischemia, [16] and myocardial infarction. [17] A common symptom is angina, which is chest pain or discomfort which may travel into the shoulder, arm, back, neck, or jaw. [4] Occasionally it may feel like heartburn.
A key symptom of coronary ischemia is chest pain or pressure, known as angina pectoris. [4] Angina may present typically with classic symptoms or atypically with symptoms less often associated with heart disease. [19] Atypical presentations are more common in women, diabetics, and elderly individuals. [8] Angina may be stable or unstable.
Typically, chest pain because of ischemia, be it unstable angina or myocardial infarction, ... [30] and these symptoms may also occur without any pain at all. [28]
