(07.02 hc) a certain type of heart-muscle disease thickens the heart muscle so that the heart chambers shrink in size. how would this disease affect a person over time, as the volume of the heart chambers continues to shrink? (2 points) the person would become more alert and anxious over time because the enlarged heart muscles would pump more blood to the brain than before the disease progressed. the person would develop low blood pressure and feel faint because the heart will be pumping less blood with each heartbeat. the person would become more tired and weak because the volume of oxygenated blood pumped with each heartbeat would decrease over time. the person would develop high blood pressure because the thicker heart muscles and smaller heart chamber volume would cause more pressure in the heart.
