Heart failure is not typically attributed directly to smoking as a primary risk factor, unlike the other listed cardiovascular diseases. While smoking can contribute to a range of cardiovascular problems, including hypertension, stroke, and peripheral vascular disease, its association with heart failure is more indirect and less clear.

Hypertension is strongly linked to smoking due to nicotine's stimulatory effects on the cardiovascular system, leading to increased blood pressure. Stroke is also closely associated with smoking, as it contributes to atherothrombotic processes that can lead to cerebrovascular events. Peripheral vascular disease is caused by atherosclerosis, which is significantly accelerated by smoking, leading to decreased blood flow and increased risk of complications associated with the limbs.

In contrast, heart failure often results from a combination of factors including underlying conditions like coronary artery disease, hypertension, or valvular heart disease, but the direct causal link to smoking is not as prominent as in other cardiovascular conditions. Thus, heart failure stands out as a cardiovascular disease not typically linked to smoking in a direct manner.
