The molecular mechanisms responsible for electronechanical derangements found in primary left venticular (LV) hypertrophy have not been clearly elucidated Of particular is the interest is the voltage gated L-type Ca curreent (Ica1) which plays crucial role in the EC-coupling. This study aimed to investigate cardiomuocyte Ica(1) in newly developed lime of rats namely HHR (hypertrophy have not be…
