Cardiac Troponin I and Acute Myocardial Infarction

Myocardial infarction is defined pathological perspective as myocardial cell death (necrosis) due to prolonged ischemia. Infarcts are classified temporally according to the pathologic appearance as follows: acute (6 h to 7 days); healing (7 to 28 days), healed (29 days or more). 

The diagnosis of acute myocardial infarction (AMI) is defined by the World Health Organization as the presence of at least two of three criteria: typical symptoms (i.e., chest pain), electrocardiogram (ECG) abnormalities and increased cardiac enzyme levels.

Cardiac troponin I is a sensitive cardiac biomarker which generalized be used in hospitals especially emergency department in patients with chest pain or ECG has ST elevation for the early detection and diagnosis of myocardial infarction.

From empirical studies obtained and selected, the high sensitive troponin I assay has the highest diagnostic accuracy. With the use of the sensitive troponin assay, the early detection of myocardial is infarction increased by 29%.

  1. When I think of necrosis I always think of massive death of host tissue cells, therefore i wonder if necrosis is possible, what is the mortality of the Cardiac Troponin I and Acute Myocardial Infarction. I also wonder does a patient fully recover from the necrosis after being healed?

  2. This is a very great topic! So many individuals have died due to myocardial infarction. Through the early detection of Acute Myocardial Infarction, numerous of lives can be saved. I didn't know cardiac troponins are released into circulation in response to myocardial necrosis. With the accuracy being high,cardiac troponin makes for a great biomarker to be used internationally.
