80.366 -> resulting in angina,
83.336 -> myocardial infarction, or death.
87.026 -> For some people the first sign of CAD is a heart attack.
91.916 -> Over time, CAD can weaken the heart muscle and contribute to heart failure or arrhythmias.
99.566 -> Since CAD is a progressive disease, it may not be noticeable in the early stages.

173.486 -> EKG, an
175.376 -> echocardiography, stress test, chest x-ray,
179.306 -> coronary angiogram, or cardiac catheterization.
185.126 -> Non-modifiable risk factors of CAD include gender, age, and family history.

211.886 -> Especially if that family member was diagnosed before the age of 50.
217.166 -> Risk factors include tobacco, which increases inflammation.
222.116 -> High cholesterol, which can increase risk of formation of plaque and atherosclerosis.
