Answer :
The correct answer would be option D, Arnold's risk for coronary heart disease.
The nature of the physician's concern is Arnold's risk for coronary heart disease.
Explanation:
A coronary heart disease is a disease which builds up in a human body when the arteries of the heart become narrow. These are the coronary arteries, which becomes narrow due to this disease.
Coronary arteries are responsible for supplying oxygen and blood to the heart. So when these blood vessels become narrow, there will be problem in supplying oxygen and blood to the heart. The amount of oxygen and blood will decrease while passing through the narrow channel.
The Coronary Heart Disease is caused by high cholesterol levels, which gets stuck on the walls of the arteries and make them narrow. So because Arnold has a history of heart diseases, and also his cholesterol levels are not normal, and also he is over weight, so the physician is more concerned about the coronary heart disease.
