Which health condition is often a comorbidity of coronary artery disease?

Coronary artery disease (CAD) often occurs alongside diabetes due to the ways both conditions affect the cardiovascular system. Diabetes leads to higher blood glucose levels, which can damage blood vessels and accelerate the process of atherosclerosis—the buildup of fatty deposits in the arteries. This progression contributes significantly to the development and worsening of CAD. Additionally, individuals with diabetes frequently experience other risk factors for heart disease, such as obesity and hypertension, which further increase their susceptibility to CAD.

While the other listed conditions—skin cancer, chronic obstructive pulmonary disease, and gastroesophageal reflux disease—may have various associations with cardiovascular health, they are not as directly correlated with CAD as diabetes is. This makes diabetes a particularly important comorbidity to consider when assessing an individual's risk for coronary artery disease.
