Enterovirus but not Parvovirus B19 is associated with idiopathic dilated cardiomyopathy and endomyocardial CD3, CD68, or HLA-DR expression.

We assessed Enterovirus (EV) &Parvovirus B19 (PVB19) genomes and CD3, CD68&HLA-DR detection in dilated cardiomyopathies (DCM). EV&PVB19 genomes and CD3, CD68&HLA-DR were detected by PCR and immunohistochemistry assays in 115 endomyocardial biopsies obtained in 13 idiopathic DCM (iDCM) and 10 explained DCM (eDCM) patients. Results were compared with those of 47 atrial surgical samples (47 surgery controls) and 22 autoptic cardiac samples (11 healthy heart controls) (2008-2014, Reims, France). EV was detected in 23.1% of iDCM patients but not in eDCM and controls (P = 0.003) (viral load 803 copies/µg). PVB19 was detected in 76.9%, 80.0%, 63.6% and 78.2% of iDCM, eDCM, healthy heart and surgery controls (P = 0.99) with a mean viral load of 413, 346, 1,428, and 71 copies/µg. CD3, CD68 or HLA-DR were detected in 100 and 50% of EV and PVB19 "mono-infected" iDCM patients. EV was exclusively detected in iDCM cases in association with CD3, CD68, or HLA-DR indicating that EV could be an etiological cause in a subset of iDCM cases. By contrast the equal frequent detection of PVB19 in iDCM cases and controls without association with CD3, CD68, or HLA-DR suggested that PVB19 could be a bystander in many DCM cases. J. Med.

Randomised comparison of femoral versus radial approach for percutaneous coronary intervention using abciximab in acute myocardial infarction: results of the FARMI trial.

OBJECTIVE: To compare bleeding complications and results of percutaneous coronary intervention (PCI) between patients treated by radial and femoral approaches for acute myocardial infarction (AMI,) and using abciximab and 5 French guiding-catheters. PATIENTS: 114 consecutive patients with AMI were prospectively randomised. Exclusion criteria were a history of coronary artery bypass graft, cardiogenic shock, atrioventricular block, and contraindication to abciximab or a negative Allen test. Local haemostasis was achieved by manual compression. RESULTS: Baseline characteristics were similar between the two groups. Peripheral arterial complication rates and delays to patient ambulation were significantly lower in the radial group than in the femoral group, whereas in-hospital stay was similar between the two groups. A cross over was more often necessary in the radial group than in the femoral group. Coronary angiography duration and fluoroscopy time were significantly longer in the radial group than in the femoral group, whereas PCI duration was similar in both groups. CONCLUSIONS: The FARMI trial showed that the radial route lowered peripheral arterial complication rates and allowed earlier ambulation, despite no significant benefit on the duration of hospitalisation.
