Symptoms of unstable angina are the same as those of stable angina, however the pattern of the symptoms changes. [7] 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 ...
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.
In unstable angina, symptoms may appear on rest or on minimal exertion. [6] The symptoms can last longer than those in stable angina, can be resistant to rest or medicine, and can get worse over time. [8] [10] Though ACS is usually associated with coronary thrombosis, it can also be associated with cocaine use. [11]
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, says Dr. William Zoghbi, chair of ...
In stable angina, symptoms occur with exercise or emotional stress, last less than a few minutes, and improve with rest. [4] Shortness of breath may also occur and sometimes no symptoms are present. [4] In many cases, the first sign is a heart attack. [5] Other complications include heart failure or an abnormal heartbeat. [5]
Unlike cases of atherosclerosis-related stable angina, these symptoms are often unrelated to exertion and occur in night or early morning hours. [4] However, individuals with atherosclerosis-related unstable angina may similarly exhibit night to early morning hour symptoms that are unrelated to exertion. [5]
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. Unstable angina is most often associated with emergent, acute coronary syndromes. [20]
