Cardiovascular disease is a result of ____________.

Question

BlackTom AI · Accepted Answer

The question asks about the cause of cardiovascular disease in terms of a physiological process.
Option 1: 'artery walls thickening because too much sugar is in the blood' This statement incorrectly attributes arterial thickening directly to high blood sugar levels in such a simplifed way; while high glucose can contribute to vascular damage in diabetes, the phrase implies a direct and sole cause of artery thickening that isn’t standardly framed as the primary mechanism for cardiovascular disease.
Option 2: 'artery walls thickening due to blood thickening' Blood does not literally thicken in a way that causes arterial walls to thickening; this option mixes concepts (blood viscosity and arterial wall changes) in an inaccurate manner and does not reflect the common pathophysiology of cardiovascular disease.
Option 3: 'artery walls weakening from smoking' Smoking damages vessels and increases cardiovascular risk, but the wording here emphasizes weakening as the main mechanism; while smoking contributes to atherogenesis and other pathologies, the description here is a partial and incomplete portrayal of the primary process.
Option 4: 'plaque buildup in arteries' This option describes the buildup of atherosclerotic plaque within arterial walls, which is a central and widely recognized mechanism underlying many forms of cardiovascular disease, including heart attack and stroke. Plaque accumulation narrows and stiffens arteries, promoting reduced blood flow and potential rupture.
Thus, the option that aligns with the established pathophysiology of cardiovascular disease by detailing plaque accumulation is the one describing plaque buildup in arteries.
