Comparative StudyClinical impact of selective spasm provocation tests: comparisons between acetylcholine and ergonovine in 1508 examinations.
There are few reports regarding the concordance of coronary arterial response between acetylcholine (ACh) and ergonovine (ER) spasm provocation tests. ⋯ Thus, both selective ACh and ER tests were useful as spasm provocation tests.

Comparative StudyTroponin I as a specific marker of myocardial injury: from theory to clinical practice in the diagnosis of acute coronary syndrome.
To assess the diagnostic accuracy of troponin I (TnI) elevation in patients with acute coronary syndrome (ACS) in the emergency department (ED). ⋯ Abnormal values of TnI were detected in a variety of diseases not related to ACS. Even if troponin release indicates myocardial injury, it is not always synonymous with infarction or ischemia. A misinterpretation of TnI elevation may give rise to a diagnostic dilemma and cause unnecessary morbidity. An integration of biomarkers (TnI and CK-MB), ECG and WMSI will help identify false-positive ACS patients and avoid inappropriate admissions to CCU.
