The secondary objective is to determine whether 99mTc-NC100692 uptake correlates on a segmental basis with fibrosis visualised by late Gd-enhancement MRI. The tertiary objective is to evaluate the relationship between the extent of fibrosis assessed by 99mTc-NC100692 uptake and mean longitudinal strain as determined by speckle tracking echocardiography.\n\nThe primary hypothesis is that there is an increased uptake of 99mTc-NC100692 in patients with HCM fibrosis detected by MRI. The secondary hypothesis is that the location and extent of increased 99mTc-NC100692 uptake will correlate with localization and extent measurements of fibrosis by Gd-enhanced magnetic resonance imaging. The tertiary hypothesis is that the extent of fibrosis assessed by the number of segments with and the magnitude of 99mTc NC100692 uptake will correlate with mean longitudinal strain as determined by speckle tracking echocardiography.\n\nACS Population:\n\nThe objective is to determine whether 99Technetium-NC100692 uptake in patients with ACS (MI) can serve as a marker for scar formation as detected by contrast-enhanced MRI during the process of myocardial remodelling after the ischemic insult.\n\nThe primary hypothesis is that there is an increased uptake of 99Technetium-NC100692 in patients following an ACS event (MI) and that the location and extent of increased 99Technetium-NC100692 uptake will correlate with the presence and extent of scar as detected by contrast-enhanced magnetic resonance imaging.\n\nNormal Control Population:\n\nPreliminary analysis of images from HCM population showed a diffuse, low grade uptake of 99Technetium-NC100692 in non-hypertrophied myocardial segments. Although not entirely unexpected, comparison with control images will allow for quantification of low grade fibrosis and low grade uptake.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'HCM Population:\n\nInclusion Criteria:\n\n* Diagnosis of HCM as defined as: Interventricular septal thickness greater than 12 mm on a 2D echocardiogram, or septal: posterior wall thickness as measured on parasternal long axis view of \\>1.3 in the absence of secondary causes of cardiac hypertrophy such as aortic stenosis and systemic hypertension.\n\nExclusion Criteria:\n\n* Concomitant diseases that can lead to myocardial hypertrophy including valvular heart disease and uncontrolled hypertension.
