Characteristics may further be described as being interspecific, intraspecific, and conspecific. Interspecific Interspecificity (literally between/among species), or being interspecific, describes issues between individuals of separate species.
Coronary heart disease (CAD) is the most common of many types of heart disease, not only in men but also in women. It is caused by atherosclerosis, or hardening of the arteries, which occurs when plaque from cholesterol and other substances accumulate in the arteries.
Heart disease may also be caused by problems a person is born with, known as congenital heart defects. Symptoms of heart defects in children can include pale gray or blue skin (cyanosis), swelling in the legs, abdomen or around the eyes, and shortness of breath during feeding in infants (causing poor weight gain), according to the Mayo Clinic.
