Abnormally high values of cardiac troponin i in hypertrophic cardiomyopathy and diastolic heart failure

Abstract

This paper presents a 73-year old woman who was hospitalized in the Intensive care unit because of shortness of breath and atypical chest discomfort two hours ago. Blood pressure on admission was very high (240/130 mmHg), cardiac troponin I was above the reference value (2,1 ng/ml) and initial ECG recording was suggestibile for myocardial infarction without ST elevation. Echocardiographic evaluation and coronary arteriography that followed rule out acute coronary syndrome as a cause of increased cardiac troponin.
