Upon analysis of the participantsâ urine after smoking the hookah, compared with before smoking the hookah, urine levels of nicotine were increased 73-fold and levels of cotinine (which is a metabolite of nicotine) were increased four-fold.
Angina is caused by reduced blood flow to your heart muscle. Your blood carries oxygen, which your heart muscle needs to survive. When your heart muscle isn't getting enough oxygen, it causes a condition called ischemia. The most common cause of reduced blood flow to your heart muscle is coronary artery disease (CAD). Your heart (coronary) arteries can become narrowed by deposits called plaques. This is called atherosclerosis. This reduced blood flow is a supply problem â your heart is not getting enough oxygen-rich blood. You may wonder why you don't always have angina if your heart arteries are narrowed due to fatty buildup.
This buildup narrows the arteries, making it harder for blood to flow through. If a blood clot forms, it can stop the blood flow. This can cause a heart attack or stroke. A heart attack occurs when the blood flow to a part of the heart is blocked by a blood clot.If this clot cuts off the blood flow completely, the part of the heart muscle supplied by that artery begins to die.his buildup narrows the arteries, making it harder for blood to flow through.
