| description | Background
Previous studies have demonstrated that patients with heart failure have increased myocardial heat production. Coronary sinus (CS) thermography is a new method for the evaluation of left ventricular heat production.
Aims
We investigated whether the CS blood temperature is increased in patients with idiopathic dilated cardiomyopathy (DCM) compared to a control group and whether the CS blood temperature correlates with ejection fraction and systemic inflammatory activation.
Methods and results
We included 25 patients with DCM and 22 healthy subjects. Temperature measurements were performed using a new thermography catheter. Temperature difference (ΔT) was defined as the difference between the CS and RA blood temperature. The CRP levels were also measured.
ΔT was significantly greater in patients with DCM compared to the controls (0.25±0.09 vs 0.14±0.07 °C, p |

Previous studies have demonstrated that patients with heart failure have increased myocardial heat production. Coronary sinus (CS) thermography is a new method for the evaluation of left ventricular heat production.
Aims
We investigated whether the CS blood temperature is increased in patients with idiopathic dilated cardiomyopathy (DCM) compared to a control group and whether the CS blood temperature correlates with ejection fraction and systemic inflammatory activation.
Methods and results
We included 25 patients with DCM and 22 healthy subjects. Temperature measurements were performed using a new thermography catheter. Temperature difference (ΔT) was defined as the difference between the CS and RA blood temperature. The CRP levels were also measured.
ΔT was significantly greater in patients with DCM compared to the controls (0.25±0.09 vs 0.14±0.07 °C, p<0.01). ΔT and EF were inversely correlated in patients with DCM (R=0.43). We categorized patients with DCM into two groups using a CRP cut-off value of ≤1 mg/dL. ΔT in patients with high CRP was less (0.21±0.06 °C) compared to patients with low CRP (0.30±0.08 °C, p=0.01).
Conclusions
In patients with DCM increased heat production from the myocardium, as estimated from the coronary sinus blood temperature, was demonstrated, interestingly there was no correlation with systemic inflammatory activation.</description><identifier>ISSN: 1388-9842</identifier><identifier>EISSN: 1879-0844</identifier><identifier>DOI: 10.1016/j.ejheart.2006.04.002</identifier><identifier>PMID: 16731036</identifier><language>eng</language><publisher>England: Blackwell Publishing Ltd</publisher><subject>Body Temperature ; Cardiomyopathy, Dilated - physiopathology ; Case-Control Studies ; coronary sinus thermography ; Coronary Vessels - physiopathology ; dilated cardiomyopathy ; Female ; Heart Ventricles - physiopathology ; heat production ; Humans ; Inflammation - physiopathology ; Male ; Middle Aged ; Myocardial Contraction - physiology ; Stroke Volume ; Thermography</subject><ispartof>European journal of heart failure, 2007-02, Vol.9 (2), p.168-172</ispartof><rights>2007 European Society of Cardiology 2007</rights><rights>Published on behalf of the European Society of Cardiology.
