Objectives: Coronary microvascular dysfunction is present in large percentage of the population, and it has been shown to have a pathological and prognostic role in many conditions. Therefore, early detection of microvascular dysfunction is important, especially in selected populations. The aim of this study was to investigate the association of galanin with coronary flow reserve (CFR) in prehypertensive individuals to determine whether it can be used as a marker to detect microvascular dysfunction. Methods: A total of 100 participants, 50 prehypertensive and 50 normotensive were included in this prospective study. Serum galanin levels were measured and CFR was calculated by detailed transthoracic echocardiography. Results: CFR was significantly lower in the prehypertensive group (p<0.001). Also, galanin values were numerically lower in the prehypertensive group, but the difference between the groups did not reach statistical significance (p=0.062). There was no signifi- cant correlation between CFR and galanin (r=-0.161, p=0.11). Conclusion: Lower CFR values in prehypertensives suggest that microvascular dysfunction starts above normotensive values even if hypertension does not develop. The reason why low galanin levels were not statistically significant in prehypertensives and no correlation was found between galanin and CFR may be due to the small study population. Relationship between galanin, prehypertension and microvascular dysfunction will become clearer if large-scale population studies are carried out. [ABSTRACT FROM AUTHOR] more...
