Do osteopontin and galectin-3 predict the risk of ventricular tachycardia and fibrillation in heart failure patients with implantable defibrillators?
Plasma OPN and Gal-3 predict sustained VT/VF in HF patients at high risk for SCD. Larger prospective studies should outline the role of these biomarkers in predicting SCD on top of conventional risk stratification.
Circulatory impairment to exercise is common in SSc patients with exercise intolerance. Restrictive lung disease, although also common, does not limit exercise tolerance in patients capable of maximal effort.
