Fibroblasts found in the heart muscleAschoff giant cellsAlveolar macrophages containing hemosiderinEnlarged cardiac muscle fibers

Explanation

Heart failure cells refer to alveolar macrophages that have ingested hemosiderin, a pigment derived from the breakdown of red blood cells. These cells accumulate in the lungs during chronic heart failure due to pulmonary congestion. They are distinct from fibroblasts in the myocardium, Aschoff giant cells, or hypertrophied myocardial fibers.
