Myocardial infarction is death of cardiac myocytes (necrosis) caused by prolonged ischemia. The term acute "usually" refers to the time 6 hours to 7 days following pathologic appearance of the infarct.
The patient may experience ischemic-type chest discomfort with accompanying symptoms of nausea, vomiting, dyspnea, diaphoresis, lightheadedness, dizziness, syncope, fatigue and weakness.
Rapid diagnosis and risk stratification of chest pain in patients are important to identify acute myocardial infarction patients who will benefit from reperfusion therapy.
Early initiation of rhythm-control therapy led to a significantly reduced risk of major adverse cardiovascular (CV) outcomes compared with usual care (typically rate control) in patients with newly diagnosed atrial fibrillation (AF) at risk of stroke, reveals the EAST-AFNET 4* trial presented at ESC 2020.
