Would you most likely have high blood pressure if you have coronary atherosclerosis?

Depends: While high blood pressure, or hypertension is a risk factor for cardiovascular disese like stroke and heart attacks, many people may develop coronary atherosclerosis (blockages) without necessarily having high blood pressures. Other risk factors; LDL cholesterol, family history, smoking and diabetes, among others, are also important contributors.

Yes: It turns out hypertension (HTN) is considered a "modifiable risk factor" for coronary artery disease (cad)- this means that treating HTN will decrease the risk of cad. About 40%-60% who need a heart bypass have htn. Many consider HTN the greatest risk factor cad. So, yes, you are likely to have HTN if you have CAD but there are always exceptions!

No! Only a Trend: Atherosclerosis is hidden within the walls of arteries. As it progresses, the artery wall thickens & the artery typically enlarges, not narrows, for decades, thus no symptoms. In extremely advanced arterial disease (if without heart damage) the pulse pressure widens because the arteries get stiffer. But transient exercise, emotions, aortic valve leak, avms, etc. Also increase pulse pressure.
