Study Notes

Impact of Cigarette Smoking on Health

Cigarette smoke contains toxic chemicals, including nicotine, harmful to endothelial cells.
Damage to endothelial cells can initiate the development of atherosclerotic plaques.
Smoking promotes increased blood clotting, raising the risk of cardiovascular events.
Low-density lipoprotein (LDL) cholesterol levels are elevated by smoking, while high-density lipoprotein (HDL) cholesterol levels are decreased.
The imbalance in cholesterol levels accelerates the progression of atherosclerosis.
Vasoconstriction caused by smoking narrows arteries further, heightening the risk of heart attacks and strokes.
Passive smoking also inflicts similar harmful effects on cardiovascular health as active smoking.
