Coronary slow flow is not an adverse prognostic factor in MINOCA patients in the 5-year follow-up

Introduction: The research aimed to compare the characteristics and outcomes of myocardial infarction with non-obstructive coronary arteries (MINOCA) patients slow flow (CSF) vs. normal (no CSF) in a 5-year follow-up. Material methods: Between 2010–2015 were identified 111 as having final MINOCA diagnosis available calculated corrected TIMI frame count (cTFC). CSF was defined cTFC greater than 27 frames per second any three arteries. primary endpoint major adverse cardiovascular events rate, cardiac death, infarction, or hospitalization due angina. Results: mean 28.9 ± 6.1 (median: 28, IQR 24–33; min-max: 19–58). 62 (55.9%) had flow, 49 (44.1%) CSF. Patients did not differ sex (females no CSF: 58% 61%, p = 0.7) age (63 15 years 63 13 years, 0.8). characterized higher rates chronic kidney disease (0 8.2%, 0.035). No statistically significant difference observed for analysed points. MACE 9.6% 14.3% (HR 0.80, 95% CI 0.28–2.96, 0.7), respectively. Conclusions: associated risk among at five years.
