Biological process

negative regulation of Wnt receptor signaling pathway involved in heart development, negative regulation of Wnt receptor signalling pathway involved in heart development, negative regulation of Wnt-activated signaling pathway involved in heart development

Any process that decreases the rate, frequency, or extent of the series of molecular signals initiated by binding of Wnt protein to a frizzled family receptor on the surface of the target cell, resulting a change in cell state that contributes to the progression of the heart over time.
