• W4306317914 abstract "Abstract Introduction The clinical evaluation of symptomatic women is challenging due to their varying clinical presentation. Women patients with intermediate or high pre-test probability for coronary artery disease – even asymptomatic or with non-informative exercise test should be referred for further focused diagnostics. Myocardial perfusion imaging with single photon emission computed tomography (SPECT) is one of the most performed non-invasive cardiac imaging tests to diagnose CAD or coronary microvascular dysfunction (CMVD). Purpose To evaluate the correlation between various CAD symptoms and cardiac SPECT results in women patients undergoing examination due to diagnosis of CAD or CMVD. Methods During the period from 2018 till 2021 we performed cardiac SPECT for women patients with intermediate or high pre-test probability or non-informative exercise test. Patients were divided into 2 groups: normal myocardial perfusion or true myocardial perfusion defect, defined as area of ischemia ≥10% of the left ventricle myocardium mass. According to the clinical symptoms patients were categorized in “asymptomatic”, “atypical symptom” and “patients with chest pain” group. The presence of CMVD and CAD in each group was determined by invasive coronary angiography or computed tomography angiography. Results In 4 years, SPECT was performed in 726 women patients. The most common presented symptoms were: chest pain (n=487, 67.1%), dyspnea (n=323, 44.5%), tachycardia and palpitations (n=117, 16.1%), fatigue (n=129, 17.8%), headache (n=28, 3.86%) and excessive sweating (n=15, 2.1%). 104 (14.3%) patients were asymptomatic, 487 (67.1%) with chest pain and 135 (18.6%) with atypical symptoms. True myocardial perfusion defect was detected in 125 patients (17.2%). The obstructive CAD was found in 32 cases (25.6%; 4.4% of all SPECTs). The CMVD was diagnosed in 68 women (54.4%; 9.4% of all SPECTs). In asymptomatic patient group obstructive CAD was diagnosed in 5 (4.8%) cases, in chest pain group – 11 (2.3%) cases and in atypical symptom group – 16 (11.9%) patients (p&lt;0.001). None of asymptomatic women had CMVD. The CMVD was detected in 53 (42.4%; 7.3% of all) cases in chest pain group and in 14 (11.3%; 1.9% of all) patients in atypical symptom group (p=0.006). Conclusion Women patients with typical chest pain were more likely to have CMVD, but with atypical symptoms – CAD. Since women are in a very high cardiovascular risk group in Latvia, the cardiac SPECT is highly recommended for detection of CAD and CMVD, especially in patients with atypical symptoms.
