Overview
Positron Emission Tomography (PET) may be helpful in the diagnosis of ischemia in patients with hypertrophic cardiomyopathy. PET studies have demonstrated that coronary flow reserve is reduced in patients with HCM. Those patients who subsequently died had a greater reduction in coronary flow reserve at baseline. It has been hypothesized that this ischemia may mediate in part the higher risk in sudden cardiac death.
Other Imaging Findings

| Class I |
| 1. For patients with HCM who are candidates for SRT and for whom there is uncertainty regarding the presence or severity of LVOTO on noninvasive imaging studies, invasive hemodynamic assessment with cardiac catheterization is recommended(Level of Evidence: B-NR)
2. In patients with HCM with symptoms or evidence of myocardial ischemia, coronary angiography (CT or invasive) is recommended.(Level of Evidence: B-NR) 3. In patients with HCM who are at risk of coronary atherosclerosis, coronary angiography (CT or invasive) is recommended before surgical myectomy.(Level of Evidence: B-NR) |

| Class I |
| "1. Coronary arteriography (invasive or computed tomographic imaging) is indicated in patients with HOCM with chest discomfort who have an intermediate to high likelihood of CAD when the identification of concomitant CAD will change management strategies. (Level of Evidence: C) " |
| Class IIa |
| "1. Assessment of ischemia or perfusion abnormalities suggestive of CAD with single photon emission computed tomography (SPECT) or positron emission tomography (PET) myocardial perfusion imaging (MPI; because of excellent negative predictive value) is reasonable in patients with HCM with chest discomfort and a low likelihood of CAD to rule out possible concomitant CAD. (Level of Evidence: C) " |
| Class III (No Benefit) |
| "1. Assessment for the presence of blunted flow reserve (microvascular ischemia) using quantitative myocardial blood flow measurements by PET is not indicated for the assessment of prognosis in patients with HCM. (Level of Evidence: C) " |
