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.
Because valvular heart disease can cause the heart to work harder, enlarge, and ultimately lead to congestive heart failure, symptoms like shortness of breath, fatigue, fainting, chest pain, and ankle swelling may appear as the disease progresses.
