A rare case of persistent troponin elevation in a patient with chronic heart failure

Abstract We present the case of a woman diagnosed with hypertrophic cardiomyopathy who suffered a myocardial infarction when she was 28 years old, without coronary artery disease on coronary angiography. Two years later, she presented signs of heart failure and left ventricular systolic dysfunction with persistent troponin I elevation, followed by progressive worsening of ventricular dysfunction.
