What term describes heart disease?

The term that describes heart disease is "cardiac." This term specifically refers to anything related to the heart. Heart disease encompasses various conditions that affect the heart's function, including coronary artery disease, heart rhythm problems, and others. By using "cardiac," healthcare professionals can effectively communicate about heart-related issues, ensuring that the focus remains on the specific organ and its associated diseases.

In contrast, other choices do not directly relate to heart disease. For instance, "stroke" pertains to a condition that involves a disruption of blood flow to the brain rather than the heart. "Obesity" indicates an excess of body weight, which can be a risk factor for heart disease but is not itself a description of heart disease. "Dementia" refers to a decline in cognitive function and memory, again not related to heart conditions. Thus, the term "cardiac" is the appropriate descriptor for heart disease.
