Cardiovascular magnetic resonance-determined left ventricular myocardium impairment is associated with C-reactive protein and ST2 in patients with paroxysmal atrial fibrillation

Table 1 Clinical characteristics of the study population with atrial fibrillation (AF) and healthy controls

Variables	Paroxysmal AF patients (n = 80)	Healthy controls (n = 20)	P-value
Age, years	50 ± 10	50 ± 5	0.807
Male (%)	71 (88.8)	17 (85.0)	0.644
Time from the first diagnosis, months (median, IQR)	23, 6–47	–	–
Systolic BP, mmHg	124 ± 11	119 ± 12	0.117
Diastolic BP, mmHg	80 ± 10	78 ± 9	0.427
AF burden, min/day (median, IQR)^a	35, 15–89	–	–
Smoking (%)	33 (41.3)	8 (40.0)	0.919
BMI, kg/m²	26.8 ± 3.2	26.7 ± 1.6	0.829
Heart rate, beats/min	72 ± 12	63 ± 2	< 0.001

Data are expressed as mean ± SD or number (%) or median, IQR
BP blood pressure, AF atrial fibrillation, BMI body mass index
^aEach patient enrolled in this study had at least one 24-h Holter monitoring. The AF burden was calculated with the recorded episodes of AF for 31 AF patients with reported AF during the Holter monitoring
