Search for methods to prevent sudden cardiac death due to acute myocardial infarction. First a new, (widely appreciated) model of experimental angina pectoris was developed. With the help of this method a number of antianginal and other cardiac drugs as well as their effect on hemodynamic and cardiac metabolic changes were studied.
Unstable angina (UA) (also "crescendo angina"; this is a form of acute coronary syndrome) is defined as angina pectoris that changes or worsens or begins suddenly at rest. [12] 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]
Isosorbide mononitrate is a nitrate-class drug used for the prevention of angina pectoris. [7] The sublingual patch has an onset of five minutes and a duration of action of one hour. The oral, slow release tablet has an onset of thirty minutes, and a duration of 8 hours.
Microvascular angina is a type of angina pectoris in which chest pain and chest discomfort occur without signs of blockages in the larger coronary arteries of their hearts when an angiogram (coronary angiogram) is being performed. [66] [67] The exact cause of microvascular angina is unknown.
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 ...
Cardiac ischemia may be asymptomatic or may cause chest pain, known as angina pectoris. It occurs when the heart muscle, or myocardium, receives insufficient blood flow. [10] This most frequently results from atherosclerosis, which is the long-term accumulation of cholesterol-rich plaques in the coronary arteries.
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 ...
Consequently, this angina has come to be reported and referred to in the literature as Prinzmetal angina. [3] A subsequent study distinguished this type of angina from classical angina pectoris further by showing normal coronary arteries on cardiac catheterization. This finding is unlike the typical findings in classical angina pectoris, which ...
