Abstract

Background

While earlier studies have indicated that patients with coronary slow flow (CSF) tend to have favorable outcomes, long-term prospective data remain limited.

Aim

This study aimed to assess the long-term clinical significance of CSF and its effect on cardiac function.

Study Design

A 5-year clinical follow-up was conducted to assess cardiac function in patients with CSF using both conventional and speckle-tracking echocardiography.

Methods

Nineteen patients diagnosed with CSF were included. Echocardiographic and strain parameters were recorded at baseline and re-evaluated after five years. Clinical follow-up was maintained throughout the study period.

Results

No significant changes were observed in echocardiographic or longitudinal strain parameters, all of which remained within normal limits. During the follow-up, there were no cases of mortality, cardiac-related hospitalizations, or acute coronary syndromes.

Conclusion

Patients with CSF demonstrated preserved cardiac function and a favorable long-term prognosis. Ongoing medical treatment likely played a role in maintaining these outcomes.
