Unstable angina is a medical emergency and requires urgent medical treatment from a doctor. [5] It has at least one of these three features: [13] it occurs at rest (or with minimal exertion), usually lasting more than 10 minutes; it is severe and of new-onset (i.e., within the prior 4–6 weeks)
Angina comes from the latin angere, which means to strangle, and pectoris comes from pectus, meaning chest—so angina pectoris loosely translates to “strangling of the chest”, which actually makes a lot of sense, because angina pectoris is caused by reduced blood flow which causes ischemia to the heart muscle, or lack of oxygen to the ...
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.

Subsequent to this is a period of "myocardial stunning," in which reversible ischemic damage is taking place. At approximately 30 minutes after the onset of total ischemia the damage becomes irreversible, [6] thereby ending the phase of myocardial stunning. The generation of oxygen-derived [free radicals] during the initial period of ...
A study led by Mayo Clinic found a “widening gap between lifespan and healthspan" among 183 countries. The lead researcher and another doctor discuss the drivers of poor health late in life.
Previously, unstable angina was assumed to be angina pectoris caused by disruption of an atherosclerotic plaque with partial thrombosis and possibly embolization or vasospasm leading to myocardial ischemia. [9] [10] However, sensitive troponin assays reveal rise of cardiac troponin in the bloodstream with episodes of even mild myocardial ...
The sicko ran off, but then groped another 16-year-old girl in the buttocks about 10 minutes later and six blocks away on Guy R. Brewer Boulevard near 115 Avenue, according to authorities.
