Troponin Release Induced by Procedure - Czech

Myocardial Injury Related to Coronary Angiography in the Era of High-sensitivity Cardiac Troponin I

A prospective study aiming to analyse the relation between different variables and high sensitivity troponin I (hsTnI) elevation within a group of patients undergoing a coronary angiography with or without subsequent percutaneous coronary intervention.

The study tries to seek potential causes and context of subclinical myocardial injury within patients with baseline concentration of hsTnI below the 99th percentile value upper reference limit or with demonstrated fall of hsTnI levels.

Inclusion Criteria:

• stable or unknown coronary artery disease
• acute coronary syndrome without ST-segment elevation meeting the criteria of low risk with demonstrated fall of cTn levels

Exclusion Criteria:

• acute coronary syndrome with persistent ST-segment elevation
• acute coronary syndrome without ST-segment elevation meeting the criteria of high or intermediate risk
