Background: In the clinical setting there are conflicting results regarding the role of inflammatory activation in atrial fibrillation (AF). Coronary sinus (CS) thermography assesses myocardial heat production and is correlated with inflammatory states. We investigated in patients with AF whether 1) there is increased CS blood temperature and 2) the correlation of heat production with systemic inflammation. Methods: We included patients with AF and subjects with sinus rhythm. C-reactive protein (CRP) levels were measured in all patients. CS and right atrium (RA) blood temperature measurements were performed by a dedicated 7F thermography catheter. Delta T was calculated by subtracting RA from CS blood temperature. Results: We included 47 patients with AF and 23 subjects with sinus rhythm. We stratified patients with AF into two groups: normotensive (AFN) and hypertensive (AFH). Delta T was lower in the RA compared with the CS in AFH (37.27 +/- 0.52 degrees C vs 37.47 +/- 0.54 degrees C, p |
